The Division requests that EFR include the additional costs for removing the identified ACM in the estimate
of costs to decontaminate and decommission the mill. The Division will review the revised reclamation cost
estimates, when available, to verify that these costs have been included in the reclamation cost estimates.

Response:
Energy Fuels Resources (USA) Inc. (EFRI) submitted asbestos inspection reports as
Attachment A to EFRI (2012) for the following facilities:
 Administration Building
 Mill Building, Boiler Plant, Scale House, and the Sample Plant
 Maintenance-Warehouse Facility
 SX Building
The asbestos inspection report for the Mill Building, Boiler Plant, Scale House, and the
Sample Plant erroneously included inspection information for the Maintenance-
Warehouse Facility. The asbestos inspection report for the Mill Building, Boiler Plant,
Scale House, and Sample Plant has been revised and the report is provided as
Attachment A to this response document.
Costs for removing asbestos containing material (ACM) identified in the asbestos
inspection reports are currently incorporated in the annual surety estimates. These
costs will also be included in the reclamation cost estimate in the next version of the
Reclamation Plan.

ENGINEERING DRAWINGS
Based on review of the above Response, the Division finds that although EFR provided narrative descriptions
of the changes it intends to make to engineering drawings, revised drawings were not submitted with
interrogatory responses. Rather, EFR committed to provide revised engineering drawings with the “next
revision of the Reclamation Plan”. The Division will review the revised engineering drawings, when
available, to verify that these changes to the drawings have been made. Because EFR submitted neither
revised engineering drawings nor the revised Reclamation Plan in its interrogatory response, this
interrogatory will remain open.

Response:

Revised engineering design drawings are provided as Attachment B and incorporate (1)
the applicable proposed changes listed in EFRI (2012) for this interrogatory, (2) the
revised cover design based on technical analyses presented in EFRI (2012) and
included as attachments to this response document, and (3) recent topography provided
by EFRI.

CQA/CQC PLAN, COVER CONSTRUCTABILITY, AND FILTER AND ROCK RIPRAP
LAYER CRITERIA AND PLACEMENT

The Division finds EFRs’ Response to the first item of this interrogatory pertaining to materials to be
placed into Cell 1 – i.e., EFR’s commitment to revise all sections of the CQA/CQC Plan, Technical
Specifications, and the text of the Reclamation Plan itself to preclude placement of tailings into the Cell
1 Disposal Area, and to identify the Cell 1 area as the “Cell 1 Disposal Area” in all documents – to be
acceptable. These revised documents will need to be reviewed, when available, to verify that these
changes have been made. Because these revised documents were not submitted in its interrogatory
response, this interrogatory will remain open.
Based on its review of the section of EFR’s response pertaining to the constructability of the currently
proposed cover system having such extremely flat topslope inclinations, the Division is unable to concur
with EFR’s contention that such flat inclinations can be constructed uniformly and reliably over the
entire required topslope area, as insufficient supporting information and justification have been
submitted to satisfactorily support the contention. This issue needs to be addressed before appropriate
conclusions can be reached.
In addition to the Division’s uncertainties related to the constructability of the currently proposed cover,
insufficient information has been provided in Attachment A (Technical Specifications, Section 8) and
Attachment B (CQA/CQC Plan, Section 6) to the Rev 5.0 Reclamation Plan or in EFR’s response
regarding the means and procedures that would be implemented for controlling, verifying, and
documenting layer thicknesses and final grades across the top portions of the cover. Examples of
information missing that should be provided are discussions regarding the need for use of Global
Positioning System (GPS) and computer terrain modeling technology and how these might be combined
to provide for a Computer Aided Earthmoving System (CAES) for verification of soil compaction and
thicknesses of layers as they are being installed and undergoing compacted during each pass of the
compaction equipment over placed loose lifts (e.g., Caterpillar 2003). The advantage of this
methodology is that it provides a continuous record in a continuous manner across the entire cover area
footprint, rather than acquiring data at a series of isolated points. Discussions of soil density tests and
independent land surveys for demonstrating the effectiveness of the CAES method, and procedures that
may be used for visual monitoring of the CAES-verified compaction process and review of CAES-
generated computer records for each layer of soil placed by on-site QC personnel, should also be
provided. A more detailed discussion should also be provided of companion sand cone tests and
moisture tests to be performed along with nuclear tests until a sufficient number of have been performed
to demonstrate a clear correlation between results obtained using these test methods. Similar procedures
to those described here have been accepted and are in use at the Crescent Junction, Utah uranium
tailings repository (e.g., see U.S. DOE-EM/GJ1547 [DOE 2012]).
The Division finds the filter layer gradation and permeability criteria and proposed construction quality
assurance testing procedures and frequencies to be acceptable. The revised CQA/CQC Plan will need to
be reviewed, when available, to verify that these changes have been made. Because the revised
CQA/CQC document was not submitted in its interrogatory response, this interrogatory will remain
open.
The Division also finds EFR’s commitment to revise Section 5.7.1 of the CQA/CQC Plan and Section
8.2.4 of the Technical Specifications to include a required minimum thickness of the rock riprap layer
equal to 1.5 times the D50 rock riprap diameter of 7.4 inches, or the D100 of the rock riprap materials,
whichever is greater, to be acceptable. The revised CQA/CQC Plan and revised Technical Specifications

and Filter and Rock Riprap Layer Criteria and Placement Page 4 of 60
will need to be reviewed, when available, to verify that these commitments will be faithfully
implemented. Because these revised documents were not submitted in its interrogatory response, this
interrogatory will remain open.
Based on review of the information provided in the Response with respect to rock riprap placement and
construction quality assurance testing, the Division notes that EFR did not address certain additional
specific recommendations included in Appendix F (Rock Placement Procedures for Erosion Protection)
of NUREG-1623 (NRC 2002) in their response to this interrogatory, but which should be addressed.
Additional NUREG-1623 recommendations that should also be addressed/ implemented include the
following:
 Initial testing should be conducted to determine the gradation and the rock weight/unit volume
that will be achieved in future rock placement activities.
 No individual rock piece should exceed 90% of the riprap layer thickness
 Dumped riprap should be placed to its full course thickness in one operation and in such a
manner as to avoid displacing any underlying bedding material
 It should be declared that rearranging of individual stones by mechanical equipment or by hand
may be required to the extent necessary to obtain a well-keyed and reasonably well-graded
distribution of stone sizes and that larger pieces of riprap may require individual placement by
equipment.
 Any stones that are not firmly wedged should be adjusted and additional selected stones inserted
or existing stones replaced, so as to achieve a solid interlock.
Based on its review of the section of EFR’s response pertaining to settlement and of the referenced
revised settlement analyses, the Division is unable to assess the correctness of EFR’s conclusion
regarding cover performance with respect to settlement due to errors, omissions, discrepancies, and
insufficient information in the materials submitted. These issues need to be addressed before appropriate
and reliable conclusions can be reached. These issues are more fully discussed in Sections 7.0 and 9.0
below relative to the response to Interrogatory 07/01, Technical Analysis - Settlement and Potential for
Cover Slope Reversal and/or Cover Layer Cracking and 09/01, Technical Analysis - Liquefaction.
Evidence should also be provided that the eight UMTRCA repository sites (which EFR claims have slopes
similar to the 0.5 to 1% slopes proposed for the subject site) have performed adequately and that
demonstrates that future differential settlement of those repositories during the 200- 1,000 –year
performance period of those facilities will not occur to a degree that flattening/slope reversal of the
topslope portions of those covers would result. Such information should include currently observed
differential settlements and predictions of future settlements calibrated to the observed performance.

Response:

The Division states that they accept EFRI’s commitment to revise all sections of the
CQA/CQC Plan, Technical Specifications, and the text of the Reclamation Plan to
denote the Cell 1 area as the “Cell 1 Disposal Area” and to note that this area will not
include disposal of tailings. This information has been added to the revised Technical
Specifications and CQA/CQC Plan provided as Attachments C.1 and C.2, respectively to
this response document, for Division review. The designation of “Cell 1 Tailings Area”
to “Cell 1 Disposal Area” will be revised in Section 3.2 of the main text in the next version
of the Reclamation Plan.

R313-24-4; 10CFR40 Appendix A, Criterion 4; INT 03/1; CQA/CQC Plan, Cover Constructability,
and Filter and Rock Riprap Layer Criteria and Placement Page 5 of 60
The Division expressed concern regarding constructability of the proposed cover slopes
ranging from 0.5 to 1 percent. Cover with similar slopes have been permitted and
constructed for Uranium Mill Tailings Radiation Control Act (UMTRCA) Title I and II sites
including:
 Falls City Title I site in Texas (less than 1% cover slopes)
 Bluewater Title II site in New Mexico (0.5 – 4% cover slopes)
 Conquista Title II site in Texas (0.5 – 1% cover slopes)
 Highland Title II site in Wyoming (0.5 – 2% cover slopes)
 Panna Maria Title II site in Texas (0.5% cover slopes)
 Ray Point Title II site in Texas (0.5 – 1% cover slopes)
 Sherwood Title II site in Washington (0.25% cover slopes)
 L-Bar Title II site in New Mexico (0.1% cover slopes)
EFRI proposes to place the final cover in two phases for each cell. The first phase
would consist of placement of the majority of the cover, without the erosion protection
layer and possibly a portion of the water storage/frost protection/radon protection layer.
For Cell 2, this first phase of cover placement would take place after approval of the
Reclamation Plan and completion of the License renewal. The second phase of final
cover placement would occur after sufficient settlement has occurred from dewatering of
tailings and placement of the first phase of final cover. Between the first and second
phase of cover placement, additional interim cover would be placed in any low areas to
maintain positive drainage of the interim cover surface. Results of settlement analyses
(see Attachment E) indicate that potential differential settlement after active maintenance
will be sufficiently low that ponding and slope reversal is not expected to occur on a
cover slope of 0.5 to 1.0 percent. Work completed on the final reclamation cover, as
described above, will be credited against the annual reclamation cost update submitted
to the State of Utah on March 4th of each year.
Settlement monuments, as well as water levels within the tailings, will be monitored on a
regular basis. Settlement monuments are currently surveyed monthly with a quality
control check done annually by a certified Surveyor. A detailed standard operating
procedure (SOP) is used for the settlement monitoring. Results are reported to the
Division annually in the Annual Technical Evaluation Report (ATER). Mini-piezometers
will be installed across the each cell prior to the first phase of cover placement. This
data will provide information on settlement and dewatering of the cells to confirm the
final phase of cover can be placed and when active maintenance is no longer required.
Grading control for construction of the reclamation cover shall be achieved with Global
Positioning System (GPS) guided equipment. This requirement has been added to the
Technical Specifications as requested by the Division. The Computer Aided
Earthmoving System (CAES) is a type of GPS-guided grading control method.
Text has been added to Sections 5.2, 5.3.6, 5.4.5, and 5.6.3 of the CQA/CQC Plan to
note that a sufficient number of sand cone and moisture content tests will be performed
to provide a correlation between the sand cone and nuclear density tests.
The Division states that they accept the filter layer gradation and proposed construction
quality assurance testing procedures and frequencies. Sections 8.2.5 and 8.4.7 of the
Technical Specifications (Attachment C.1) and Section 5.7.1.2 of the CQA/CQC Plan
(Attachment C.2) have been revised to include the updated testing frequency and filter
material gradation requirements.

The Division states that they accept the proposed revisions to Section 5.7.1 of the
CQA/CQC Plan and Section 8.2.4 of the Technical Specifications to include a required
minimum thickness of the rock riprap layer equal to 1.5 times the D50 rock riprap
diameter, or the D100 of the rock riprap materials, whichever is greater. This information
has been added to the Technical Specifications (Attachment C.1) and CQA/CQC Plan
(Attachment C.2).

The Division requests additional information be added to the CQA/CQC Plan for riprap
placement based on recommendations in NUREG-1623 (NRC, 2002). The following text
has been added to Section 5.7.2 of the CQA/CQC Plan (Attachment C.2).

 Initial testing should be conducted to determine the gradation and the rock
weight/unit volume that will be achieved in future rock placement activities.
 Individual stones shall not be greater than 90 percent of the riprap layer
thickness.
 Dumped riprap shall be placed to its full course thickness in one operation and in
such a manner as to avoid displacing bedding material.
 Hand placement or rearrangement of individual stones will be required only to the
extent necessary to secure the results specified above. Larger stones may
require individual placement by equipment.
 Any stones that are not firmly wedged shall be adjusted and additional selected
stones inserted or existing stones replaced, so as to achieve a solid interlock.

The Division did not comment on EFRI’s proposed revisions to Sections 5.7.1.1, 5.7.2
and 5.7.4 of the CQA/CQC Plan for riprap placement provided in EFRI’s Response 5 to
Interrogatory 03/1 (EFRI, 2012). It is assumed that the Division is in agreement with
these proposed revisions and EFRI has included the revisions in the revised CQA/CQC
Plan (Attachment C.2).

The settlement analysis and liquefaction analyses have been revised to incorporate the
site-specific tailings data collected in October 2013 (MWH, 2015) and address the
Division’s comments provided in DRC (2013). The responses to the Divisions review
comments on these analyses and a summary of the revised results are provided in the
responses to Interrogatories 07/1 and 09/1.

SPACE CRITERIA FOR DEBRIS, RUBBLE PLACEMENT, AND SOIL/BACKFILL
REQUIREMENTS

The Division’s assessments of these responses are summarized below.
a. Maximum Void Space Percentage: EFR does not state a maximum allowable void space due to
the lack of practical means of quantifying residual void space following placement and
backfilling. In lieu of stating a void space limit, EFR incorporates practices and requirements
that were developed for the UMTRAP/UMTRCA and FUSRAP projects and that have been
demonstrated effective in limiting settlement. EFR has developed and will implement method
specifications that reflect best management practices, as documented in Attachment A “Plans and
Technical Specifications for Reclamation of White Mesa Mill Facility; Blanding, Utah”.

The practices call for compressible materials to be crushed or covered with soils (thus reducing
residual void space), while voids in and around incompressible materials will be filled with soils
or, if needed, grout.
The Division judges these specifications to be acceptable.
b. Construction Practices: Processing, placement, backfilling, and compacting of debris and
organic material are discussed in Sections 7.3 and 7.4 of Attachment A “Plans and Technical
Specifications for Reclamation of White Mesa Mill Facility; Blanding, Utah”. According to these
specifications:
 Some larger items and items with internal voids will be size reduced to expose voids so they
can be filled.
 Debris items will be placed to minimize nesting that could lead to residual voids after
backfilling.
 Compressible debris will be flattened or crushed.
 Voids will be backfilled with soil, sand, or grout as judged appropriate by CQA Manager.
These specifications constitute current best management practices and we judge them to be acceptable
given current state of knowledge.
c. Controlling Residual Voids: EFR’s QA staff will observe construction practices to ensure that
specifications for reducing void space within debris are met. The interrogatory response includes
a statement that “The QA staff will make a recommendation to the Contractor for the
implementation of a grouting program in instances when voids, either within a debris mass, or
within a vessel, cannot be properly filled with soil using conventional equipment”.
No reference to a “grouting program” exists in Attachment A “Plans and Technical Specifications for
Reclamation of White Mesa Mill Facility; Blanding, Utah”. Attachment A should be revised to formalize
this commitment.
d. Effects of Void Space on Settlement Analyses: EFR’s response is given in its response to
INT 07/1. EFR’s response notes that the cover system will not be constructed “. . . until
settlement monitoring of the subsurface shows the anticipated settlement has taken
place.”

R313-24-4; 10CFR40, APPENDIX A, Criterion 4; INT 04/1; Void Space Criteria for Debris,
Rubble Placement, and Soil/Backfill Requirements Page 8 of 60
An additional criterion should be added requiring that observed settlement has stabilized according to
some reasonable criterion.
e. Percentage of Organic Materials: EFR’s response makes several statements that, as far
as we are able to determine, are not supported or documented:
 “The percentage of organic materials to be disposed of is anticipated to be a small
percentage of the total material being disposed.”
 “. . . the biodegradation of these materials is not anticipated to compromise the integrity of
the cover system.”
EFR should provide additional information to support these statements and provide confidence that the
integrity of the cover system will not be compromised.

1. Segmenting and Placing Metallic Waste Materials: Section 7.3 of Attachment A “Plans and
Technical Specifications for Reclamation of White Mesa Mill Facility; Blanding, Utah” requires
that larger debris items be size reduced, that larger pieces are not stacked on top of each other,
that large structural shape either be placed edge to edge or spaced far enough that voids can be
filled and equipment can operate between them, that the maximum dimension be 20 feet, that the
maximum volume of any piece of debris be 30 cubic feet, and that long structural members be
placed horizontally, and that any piece not satisfying these requirements be reworked.
These provisions are considered acceptable.
1. Types of Materials and Placement Practices: Section 7.3 of Attachment A “Plans and Technical
Specifications for Reclamation of White Mesa Mill Facility; Blanding, Utah” places limits of 20
feet in length and 30 cubic feet in volume.
Although the interrogatory response mentions a maximum pipe length of 10 feet, this limit is not stated in
the Attachment A. EFR should revise Attachment A to state the maximum pipe length if it is less than 20
feet.
f. Relative Quantities of Debris, Rubble, and Contaminated Soil: EFR should revise Attachment A
to address the possibilities mentioned in the interrogatory response, should relative quantities of
debris, rubble, and contaminated soil not allow Cell 1 to be closed as planned.
g. Backfilling Voids Inside Debris Objects: EFR proposes to revise Attachment A to incorporate the
statement “The voids on the inside of the item shall be filled with contaminated soil, clean fill
soil, or grout (controlled low-strength material, flowable fill, etc...). Contaminated soil (Section
7.3.3) or clean fill will be placed outside of the items and compacted with standard compaction
equipment (where possible) or hand-operated equipment to the compaction requirements in
Specification Section 7.4.” EFR also describes measures that could be taken to ensure that voids
inside debris items are filled. These include:
 Filling the voids with soil through an existing opening
 Filling the voids with soil by cutting the item open
 Crushing the item flat (so no voids remain within
 Cutting pipes short, standing them on end, and filling them with soil
 Pumping controlled low-strength material (CLSM or grout) into a region to form a
monolithic grouted mass

R313-24-4; 10CFR40, APPENDIX A, Criterion 4; INT 04/1; Void Space Criteria for Debris,
Rubble Placement, and Soil/Backfill Requirements Page 9 of 60
These proposed revisions are acceptable and should be incorporated into Attachment A as proposed and
other documents as appropriate.
h. CLSM Compressive Strength Requirements: EFR states that grout, if required, will be formulated
to “mimic, as closely as possible, the strength and hydraulic properties of the contaminated soil
that will also be used for filling voids within the debris.”
EFR should state more specifically how these properties will be achieved and what formulation is likely
to produce the desired outcome.

Response:

The following text has been added to Section 7.4.1 of the Technical Specifications
(Attachment C.1) to reference recommendation of a grouting program, where needed. In
addition, discussion of a grouting program has been added to Section 7.3.6.

“The CQA technicians will make a recommendation to the Contractor for the
implementation of a grouting program in instances when voids, either within a
debris mass, or within a vessel, cannot be properly filled with soil using
conventional equipment.”

Organic debris will be size-reduced by crushing, chipping or shredding prior to
placement. As described in the Technical Specifications, organic material will only be
placed in lifts less than 12 inches thick and mixed with the soil and other incompressible
debris during placement to prevent pockets of organic material from being created.
Organics mixed with soil for spreading will be limited to 30 percent by volume of the
mixture. This limit has been added to the Technical Specifications (Attachment C.2).

Additional interim cover will be placed during active maintenance in any low areas on the
cover to maintain positive drainage of the cover surface due settlement including due to
debris void spaces and/or organics.

The Division requests that a maximum pipe length of 10 feet be added in the Technical
Specifications. A limit of 10 feet or less is already listed for cut pipe pieces from
demolition debris in Section 7.3.7 of the Technical
Specifications, therefore this text addition is not required.

Section 3.3 of the Technical Specifications (Attachment C.2) has been revised to include
the following text.

“If sufficient debris, rubble and contaminated soil are not available to fill Cell 1 as
designed, the footprint of Cell 1 can be reduced in size so that the horizontal
dimension extending out from Cell 2 is reduced and the lateral extent of the
disposed materials is reduced to be closer to the base of the Cell 2
impoundment. If a design modification is required for Cell 1, it will be submitted
to the Division for review and approval and these Technical Specifications will be
revised accordingly.”

Section 7.3.6 of the Technical Specifications (Attachment C.2) has been modified to as
proposed in EFRI (2012) to provide revised and additional information on backfilling of

MESA RECPLAN 5.0 R313-24-4; 10CFR40, APPENDIX A; INT 05/1; SEISMIC HAZARD
EVALUATION

Results of the Division’s review of EFR’s Response to each individual interrogatory statement in this
Round 1 interrogatory are summarized below.
As stated in the Basis for the Interrogatory and Round 1 Interrogatory statement #5, “The USGS National
Hazard Maps should not be used for developing site-specific seismic design parameters (personal
communication between Dr. Mark Petersen, Chief, National Seismic Hazard Mapping Project and Ivan
Wong of URS Corporation, 2010) for critical and important facilities. For such types of facilities, a site-
specific probabilistic seismic hazard analysis (PSHA) is recommended.” However, contrary to this
recommendation, Denison’s consultant MWH in response used the USGS National Hazard Maps
(specifically the interactive deaggregation tool) to recommend design ground motions for the facility.
EFR did not perform a site-specific PSHA as requested. Use of the National Hazard Maps does not
constitute a site-specific PSHA. The maps are four years old and are in the process of being updated.
PSHA computer software such as EZFRISK® are readily available to perform a site-specific PSHA.
Below are specific comments on EFR’s responses to the interrogatory statements:
1. Please further clarify the rationale for selecting the annual probability of exceedance of hazard
for the facility.
EFR has adequately responded to this statement.
2. Adjust the cited USGS National Hazard Map PGA value of 0.15 g for the site Vs30 as
appropriate.
EFR states that the site-specific Vs30 (time-averaged shear-wave velocity in the top 30 m) as determined
by Tetra Tech (2010) was 586 m/sec corresponding to a NEHRP site class E or soft soil. This is an
erroneous statement. A Vs30 of 586 m/sec actually corresponds to a NEHRP site class C, very dense soil
or soft rock. MWH also estimated the Vs30 for the site and concluded that the Vs30 ranged from 620 to
700 m/sec corresponding to a NEHRP site class D or stiff soil. This is also incorrect. This range in Vs30
also corresponds to a NEHRP site class C. Aside from these errors, the shear-wave velocity (Vs) estimate
for the 10 m of soil appears reasonable although SPT does not measure Vs directly and so the
uncertainties in the inferred Vs can be significant. However the technical basis for the Vs for the
remaining 20 m of interbedded sandstone needs to be provided.
As stated above and in Statement 5, a request had been made not to use the National Hazard Maps but to
perform a site-specific seismic hazard evaluation. The assumption that a site Vs30 of 760 m/sec is
appropriate for the site allowing use of the maps is problematic.
More importantly, the characterization of the site as a thin soil site where there is 10 m of soil over firm
(?) rock (Tetra Tech, 2010) indicates that a site response analysis is now required to address site effects
on ground motions. The sharp Vs contrast between the lower velocity soil and the higher velocity rock
will amplify short-period ground motions like PGA by as much as a factor of 2 for low rock ground
motion inputs. The use of Vs30 in a site-specific hazard analysis will not capture these site amplification
effects (Abrahamson, 2011). A site response analysis with a Vs profile into the rock should be performed.
Using an equivalent-linear or fully non-linear computer code would be acceptable. It is recommended
that direct measurements of Vs be made for input into the site response analysis.
3. Explain why the calculated hazard for the background earthquake PGA of 0.24 g was estimated
but ignored in the recommendation provided in Appendix E.
August 31, 2015
Division’s Assessment of EFR Responses to Rd 1 Interrogatory White Mesa Rec Plan 5.0;
R313-24-4; 10CFR40, Appendix A; INT 05/1; Seismic Hazard Evaluation Page 12 of 60
EFR did not respond to this statement. However that question is now irrelevant because of the following
actions. As recommended and agreed to by Denison in Response 3, a site-specific PSHA is the best
approach for quantifying the hazard at the site particularly from background earthquakes. Denison states
that was done as in discussed in Response 5 and as contained in Attachment A. A site-specific PSHA was
in fact not performed but the National Hazard Maps were used as stated above and below.
4. Provide information to justify the use of 15 km distance for a background earthquake Mw 6.3
event.
EFR’s response referred back to Response 3. EFR stated that the 15 km distance was selected because it
would provide a conservative PGA at the site. This response fails to answer the question. A distance of 10
km would also provide a “conservative PGA at the site”. However, this is now an irrelevant question
because a deterministic seismic hazard analysis is to be replaced by a site-specific PSHA although such
an analysis has yet to be performed.
5. Perform and report results of a site-specific PSHA in lieu of using the USGS National Hazard
Maps for developing site-specific seismic design parameters.
As commented above, a site-specific PSHA was not done and the 2008 USGS National Hazard Maps were
used. The USGS National Hazard Maps consider the Colorado Plateau in which the site is located as
part of the central and eastern U.S. with respect to ground motion prediction models. Denison’s
Attachment 5 shows those ground motion models. Recent research by the USGS (McNamara et al. 2012)
and studies for the proposed Blue Castle nuclear power plant site near Green River (Jennie Watson,
personal communication, Dec 2012) indicate that is an erroneous assumption and that the use of western
U.S. ground motion prediction models is more appropriate. Early site-specific PSHAs including an
analysis for the NRC-regulated Atlas Moab tailings site (Wong et al. 1996) and the U.S. Bureau of
Reclamation’s Glen Canyon Dam (URS 1999) used western U.S. ground motion models. This is another
reason why the National Hazard Maps should not be used for developing site-specific design parameters.
It is strongly recommended that the Next Generation of Attenuation (NGA) ground motion prediction
models be used in the site-specific PSHA for White Mesa. It is expected that the USGS will use the NGA
models for the Colorado Plateau in the 2013 National Hazard Maps.

Response:

EFRI conducted a site-specific probabilistic seismic hazard analysis (PSHA) for the
White Mesa Mill site to address the Division’s comments for this interrogatory. Three
versions of the report were submitted to the Division, with the final version submitted in
April 2015 (MWH, 2015). The Division provided a final technical review of the report on
May 28, 2015 (DRC, 2015) which stated the remaining review items were adequately
addressed. The results from this report were used to update technical analyses for the
Reclamation Plan. The updated analyses are discussed in other responses and will be
included in the next version of the Reclamation Plan.

SLOPE STABILITY

The Division finds that the revised slope stability analysis provided in the revised Attachment D to the
EFR response did not adequately address several considerations and criteria that may be important to
the analysis of the stability of the closed tailings embankment, including the following:
 No details were provided regarding shear strength data for the liner and LCRS components in
Cells 4A and 4B
 No information was provided as how the bottom liner component(s) was (were) simulated in the
global stability analysis completed for cross Section A through Cell 4B
 No details were provided regarding shear strength data for the liner and LCRS components in
Cell 2
 No information was provided as how the bottom liner component(s) was (were) simulated in the
global stability analysis completed for cross Section B through Cells 2 and 1
 Insufficient information was provided regarding:
1) the estimated in-place dry density, in-place most density, and in-place saturated density (unit
weight values) of the tailings;
2) rationale for selecting the tailings condition and tailings properties assumed in the analysis
(e.g., drained vs. undrained conditions and for selection of in-place moist tailings density vs.
in-place saturated tailings density for long-term static conditions or long-term seismic
conditions); and
3) the location of the assumed water table, e.g., if drained condition assumed;
 The discussion and Table E.1 in Attachment D of table of the material properties used in the
model did not distinguish between different material strength parameters assumed for long-term
static conditions vs. long-term seismic conditions, e.g., no discussion of percentage reduction in
strength properties for the seismic (pseudostatic) stability analysis was provided;
 No discussion of or rationale was provided for whether it may be appropriate and reasonably
conservative to assume that the tailings dewatering system might be clogged, possibly leading to
ineffective drainage at the base of the tailings cell in area including the lowest point in the
tailings bottom surface and therefore possibly result in an undrained condition within the
tailings. For such a case, undrained tailings strength relationships might suggest strength values
for the tailings that may be different than those assumed by EFR; and
 No discussion or rationale was provided for whether it may be appropriate and reasonably
conservative to assume that the strength parameters for the clay liner in the Cell 1 area might be
estimated based on the PI that would lead to the weakest strength, or estimated using some other
method that would generate the weakest estimated shear strength value for the clay liner.
The Division requests that EFR, in Attachment D, further define how the tailings total unit weight value
stated in Table E.1 (90 pcf) and used in the revised slope stability analysis was derived (or how
representative a value that value is of the tailings). For example, tailings sample results (see Appendix F,
Settlement and Liquefaction Analyses of Updated Tailings Cover Design Report, Denison 2011) indicate
that the tailings have an average specific gravity of 2.73; if a dry unit weight of 90 pcf were assumed
(Section E.3 of Attachment D of this Response,) an average tailings void ratio of about 0.89 would result.
August 31, 2015

R313-24-4; 10CFR40, Appendix A, Criterion 1; INT 06/1; Slope Stability Page 15 of 60
Based on this void ratio, the tailings bulk density would be approximately 119.4 pcf, compared to the
total unit weight of the tailings listed in Table E.1 of Attachment D of this Response of 95 pcf.
Alternatively, if an average tailings dry unit weight of 86.3 pcf were assumed (as was done in Appendix F,
Settlement and Liquefaction Analyses of the Updated Tailings Cover Design Report, Denison 2011), then
an average tailings void ratio of about 0.97 would result. Based on this void ratio, the tailings bulk
density would be approximately 117.2 pcf. EFR should reevaluate and verify that their assumed tailings
properties, calculation methodologies, and assumptions are representative, reasonably conservative, and
bounding.

Response:

The slope stability analysis has been updated to incorporate the revised cover grading
and additional site-specific tailings data collected in October 2013 (MWH, 2015). The
revised analysis is provided in Attachment D as part of the revised Appendix E, Slope
Stability Analysis, which will be included in the next version of the Updated Tailings
Cover Design Report (Appendix D to the Reclamation Plan).

The liner and LCRS components of Cells 2, 4A and 4B were not included in the slope
stability analysis because the strength parameters of these components do not affect the
reclaimed stability analysis. Failure surfaces representing the lowest calculated factors
of safety do not intersect the liner and LCRS components, even for conservatively low
shear strength conditions within the cells.

Tailings density values used in the slope stability analysis have been updated to
incorporate the results of tailings testing conducted in October 2013 (MWH, 2015). The
rationale for selecting the tailings condition and properties are provided in Attachment D.

A liquefaction analysis was conducted for the tailings and is presented in Attachment G.
The results indicate the tailings are not susceptible to earthquake-induced liquefaction
for reclaimed conditions. For materials that do not liquefy or lose shear strength with
seismic shaking, seismic slope stability is analyzed by a pseudo-static approach. The
unsaturated parameters used for the pseudo-static slope stability analyses are
conservative representations of constant volume shear strength, and no further
reduction is warranted.

The tailings are planned to be dewatered prior to placement of the final portion of cover.
The phreatic surface was estimated to be five feet above the liner system for the
analyses. Sensitivity analyses indicated that increasing the phreatic surface does not
impact the location of the critical failure surface for the slope stability analyses.

The shear strength parameters for the clay liner for Cell 1 were estimated using the
average measured PI (60) for samples meeting the placement specifications for
minimum PI and percent passing the No. 200 sieve, and the generalized relationship
between PI and effective angle of internal friction presented in Holtz and Kovacs (1981).
The relationship in Holtz and Kovacs (1981) was based on normally consolidated clays.
The stability analyses did not include cohesion, and the clay liner material will be
compacted. Therefore the shear strength parameters used in the stability analyses are
conservative values.

TECHNICAL ANALYSIS - SETTLEMENT AND POTENTIAL FOR COVER SLOPE
REVERSAL AND/OR COVER LAYER CRACKING

As discussed in the Response to Interrogatory No. 3 in Section 3.0 above, EFR did not provide settlement
performance data or settlement prediction analyses for any of the other facilities referenced by EFR as
having been constructed with a similar range of topslope inclinations. Similarly, EFR did not provide any
information demonstrating a correlation between observed settlement at these repositories and the future
settlement predictions developed for those facilities that might allow the performance of these facilities to
be evaluated with respect to their observed or predicted post-construction behavior.
The revised settlement analysis included one-dimensional analyses of both primary consolidation and
estimates of settlement due to creep associated with secondary consolidation occurring during (i) interim
soil cover placement/loading; (ii) tailings dewatering; and (iii) final cover loading. EFR also provided
estimates of seismically-induced settlement due to earthquake loading.
In its settlement analyses, EFR relies of data from settlement monuments in Cell 2 to estimate settlement
parameters (e.g., compression indices and coefficients of consolidation) for the tailings. Each monument
or monitoring point is treated independently, and the range of data and corresponding analytical results
are reported in terms of maximum, minimum and average values. Examination of the data indicates that
the 5 westernmost monuments or monitoring locations (2W12W2, 2W3, 2W3-S, and 2W4) behave very
differently than the others, with an average observed settlement of about 0.77 feet from July 1991 (on
average) to the start of dewatering in 2009, whereas the other data set only averages about 0.1 feet
during a period most typically from July 2005 to January 2009. Given the grossly different amounts of
settlement between the two sets of settlement data (and the issue not simply being a matter of greater
tailings thickness), the use of a simple average across the two sets of data seems inappropriate. More
importantly, given the relatively short time of settlement observation for the eastern monuments and the
flat shape of the settlement curves, it seems likely that significant settlement occurred prior to monitoring,
thus making this approach to settlement estimation problematic as was discussed in the first
Interrogatory. If significant portions of the settlement time histories were not captured in the eastern
monitoring data, the use of “average” values derived from the data (as apparently is the case currently)
will not represent the behavior a majority of tailings under newly added load. On the other hand, if the
range of settlement data as measured is representative of true settlement behavior, then a significant
range of possible behavior should be expected (reflective of directive in the first round of interrogatories
to consider a range of tailings ranging from fine grained slimes to coarse sands and their spatial
distribution within the impoundment cells).
EFR has attempted estimate both compression indices and coefficients of consolidation for the tailing by
curve fitting settlement data from five of the monitoring points (those possessing enough curvature to
which a curve can be fit) with theoretical settlement curves. From the plots provided in Attachment E, it
appears that something is amiss in the curve-fitting analyses since primary and secondary consolidation
appears to be happening at the same time, rather than secondary occurring after completion of primary.
Such an error would make the “back-calculated” indices and coefficients incorrect. This issue should be
examined further. Again, as stated in the first round of Interrogatories, this back-calculation or curve-
fitting approach is problematic at since the start of the settlement time history prior to monitoring is
missing and a third variable (the effective drainage length) is not precisely known. Because of this,
variance from calculated values should be expected and must be considered when evaluating subsequent
cover performance. To better address the shortcomings inherent in using this curve-fitting/back-
calculation approach, it was stated in the previous Interrogatory to “use consolidation parameters
August 31, 2015
Division’s Assessment of EFR Responses to Rd 1 Interrogatory White Mesa Rec Plan 5.0;

Potential for Cover Slope Reversal and/or Cover Layer Cracking Page 18 of 60
obtained from site-specific testing of the tailings materials, reflecting both spatial and temporal
variations in the tailings.”
The settlement analyses performed by EFR focused on evaluating settlement in the Cell 2 area only. No
discussion or analyses were provided regarding any tailings management/disposal process-related
differences such as different tailings placement methods/modes that may have occurred/might exist with
regard to the various tailings disposal cells or of the effects that such differences might have on tailings
consolidation and settlement behavior in each disposal cell area. Additionally, no discussion or analyses
were provided for differences in dewatering system designs, differences in the expected dewatering
efficiencies likely to occur between different cells (with resulting differences in statured tailings
thicknesses at the different stages in time evaluated in the settlement analyses), or differences in
thicknesses of tailings in the different cells (e.g., tailings thickness in Cell 4A varies from about 26 to 42
ft, with an average thickness of about 34 ft, vs. tailings thickness ranging from about 14.5 ft to 28.50 ft in
Cell 2).
In the Response to Item 2. of this Rd 1 interrogatory, EFR indicated that a final water level in the tailings
in Cell 2 at the end of dewatering was estimated based on dewatering analyses presented in the Revised
ICTM Report. However, the Reclamation does not contain a schedule for, a detailed description of,
measures that EFR will undertake to ensure that dewatering of Cells 2 and 3 will be completed within the
7-year time period specified in the latest Financial Surety submitted to the Division by EFR, or a shorter
time period. This is important since recent data suggests that the current rate of dewatering in Cell 2
may be on the order of 1 inch per year. As part of the additional settlement analyses that are needed to
further address differential settlement and evaluate impacts of differential settlement on cover slope
integrity/slope reversal, EFR needs to address additional requirements related to dewatering analyses,
measures, costs, and schedule for dewatering of Cells 2 and 3 as described in Section 15.3 below.
In calculating the settlement of the tailings in Cell 2, it appears that tailings above elevation 5604.95 (a
datum which seems to correspond to the average 2009 first quarter water levels plus an assumed 3-foot
perched zone thickness) have been omitted from consideration during future dewatering and placement of
the final cover (from time t1 to t2, and from t2 to t3). Even above the water table, these materials will
respond to the added stresses from cover construction and their contribution to total settlement should be
included.
Neither the response nor Attachment E presents a rationale for selecting tailings properties (e.g., specific
gravity of tailings of 2.75, moist unit weight of 100.29 pcf above the capillary fringe, long-term moisture
content of 16.2%, void ratio of 0.99 assumed for the Phase 1 analysis) to be used in the revised settlement
analyses. Further, while unit weights for the various components of the cover system have been provided,
their thickness have not all be provided, thus preventing a check of the stresses resulting from cover
placement. The thickness of each component of the cover system needs to be indicated in the calculation
spreadsheet.
Without a narrative and sample calculations for all of the spreadsheet results presented in Attachment E,
it is difficult to assess the adequacy of the analysis presented. For example, it is unclear how the bottom
elevation of the “upper zone” was determined, and then how the thicknesses of the upper and lower zones
correspond to the drainage path used to determine the time for 90% consolidation. Such clarification
need to be provided in order to assess the adequacy of the settlement calculations. General references to
calculation methodology such as “Terzaghi et al. 1996, pages 223-240” are too general to satisfy this
need for additional information.
It is unclear what time for primary consolidation was used in calculating the secondary settlement, and
the reviewer is otherwise unable to assess the results calculated by EFR. Again, a narrative and/or
sample calculations (or at least illustrative equations and a description of how specific values were
determined) should be provided for all spreadsheet calculations in order to assess their correctness.

Potential for Cover Slope Reversal and/or Cover Layer Cracking Page 19 of 60
With respect to the calculated seismically induced settlement, there appears to be errors in the
calculation process (for example, the vertical strain should be twice the resultant of the vertical strain for
15 cycles of shaking multiplied by the variable Cn [doubling is to account for the multi-directional
application of strain as described in the referenced Stewart and Whang (2003) paper]). Also, the
calculations incorrectly treat the tailings as a single layer subject to a constant amount of cyclic strain.
The tailings should be discretized into smaller, discrete layers and the stress and strain calculations
redone. Another apparent inaccuracy in EFR’s calculation is an apparent capping of shear strain
amplitude to 1.0%. In Stewart and Whang’s cyclic strain charts (Fig 3 in their paper), cyclic shear strain
values are shown up to 1%, which is a reasonable limit for compacted soils (noting that “compacted
soils” is part of the title of Stewart and Whang’s paper). However, the soils in question are uncompacted
tailings in which cyclic strains could exceed 1%. Hence, extrapolation or another calculation
methodology should be used to determine seismically induced settlement. Also, the Stewart and Whang
procedure is not well established (vetted) within the geotechnical earthquake engineering community.
Consequently, EFR should compare the results obtained using this procedure with those of a more-well
established procedure such as Tokimatsu and Seed (1987) or Ishihara and Yoshimine (1992).
In reviewing Table 2 ‘Summary of Settlement Results’, it is unclear how the values shown for “Total
Settlement five years after placement of Final Cover due to Final Cover Placement, Creep, and a Seismic
Event” in row 5 (minimum and maximum values of 0.52 to 0.83) were determined. While calculations
supporting the preceding four rows of settlement results in the table are readily identified within the
spreadsheet calculations presented in Attachment E, no explicit calculations justifying the fifth row of
values are presented. Additional information is needed.
In its assessment of differential settlement and cover cracking analysis, ERF estimates that the “maximum
potential differential settlement that could be expected between adjacent movement monitoring locations
would be on the order of 0.3 feet.” With typical spacings between monitoring locations of about 250 feet
(scaled from the figure by the reviewer, and an explicit statement of such should be provided by EFR),
this equates to an average deflection ratio (differential settlement) of about 0.12%, which is less than the
proposed minimum cover slope of 0.5%, and hence on this basis, ponding is not expected. However, the
value of 0.3 feet needs to be reassessed due to the issues just previously presented.
In assessing the potential cracking of the cover, EFR has relied upon the most critical combination of
projected settlement of a monitoring point (0.9 ft at 2W4-S) and it associated distance away from the edge
of the tailings cell (being for this monument 100 ft) to determine the greatest strain demand on the cover
based on the approach of Lee and Shen (1969). This value is then compared to the cracking resistance
based on an empirical relationship using soil index properties (Claire et al. of Morrison-Knudsen, 1993).
While this approach is reasonable, the input for Lee and Shen’s horizontal movement formula has been
incorrectly selected. In the analysis, EFR has used the average slope of the settlement profile (0.9/100)
rather than a local maximum which would include the effects of bending. This point is illustrated in the
test data and illustrative example provided in Lee and Shen’s paper: the vertical displacement between
the two ends of their 93-inch long soil beam is 1 inch, yielding an average slope of about 1%; however,
the maximum slope in their beam which includes bending is 2%, located near the middle of the beam. In
Lee and Shen’s paper, the maximum reported tensile horizontal strain is about 0.6%, derived from the 2%
maximum (not 1% average overall) slope. To be consistent with Lee and Shen, EFR should use the
expected peak slope between points, not the average between the two points. Assuming that the peak is
twice the average as in Lee and Shen’s test case (although ERF will need to provide a reasoned and
defensible value specific to this project; representative published relationships depicting cover
deformation shapes and tensile strain/distortion relationships include those included in Gourc et al.
(2010) and Rajesh and Viswanadham (2010), the maximum horizontal strain appears to be twice that of
the 0.028% previously reported, exceeding the reported maximum allowable strain of 0.05%, meaning
that the layer is expected crack. The analysis must be redone to include the effects of localized bending as

Potential for Cover Slope Reversal and/or Cover Layer Cracking Page 20 of 60
was indicated in the first round of Interrogatories, and the performance of the cover reassessed
accordingly.
Also relating to the cracking analysis, a thickness of 4.7 ft is used for the soil layer. However, the actual
thickness of the sandy clayey silt soils in the tailings cover design, which collectively serve for radon
attenuation is 8.8 ft per Figure 2-2 of the Revised ICTM Report (Denison Mines 2010). The analysis
should either be revised to reflect this value or a justification provided for the value used.
As part of the previous Interrogatory, EFR was asked to “demonstrate that the results of settlement
analyses are consistent with results of drainage/dewatering analyses, and ensure that
drainage/dewatering analyses reflect the tailings and drainage conditions (including slime drain system)
existing in each cell. In EFR’s Response, the following statement is made:
“It should be noted the assumptions made in the one-dimensional consolidation analyses of Phase 2 (i.e.
complete coverage of the tailings impoundment by an infinitely-permeable underdrain system, and
instantaneous drawdown to final water level) do not exist within the impoundment, and will result in an
underestimation of the time required to achieve 90% consolidation. The results of the tailings dewatering
analysis, which includes the 3-dimensional aspects of flow toward the underdrain strips, and a finite
underdrain permeability, are considered to provide a more reliable estimate of the duration Phase 2
consolidation.”
Unfortunately, no further reference or discussion is presented regarding the dewatering analyses, and
hence the question of time needed to reach 90% consolidation remains unresolved. Based on its
consolidation settlement analysis, EFR reports that the time to reach 90 percent of primary consolidation
due to dewatering of the tailings in Cell 2 ranges from 0.14 to 0.63 years. However, in the dewatering
analysis (see Appendix J of Revised Infiltration and Contaminant Transport Modeling Report, White
Mesa Mill Site, Blanding, Utah, by MWA 2010)), EFR reports that “the MODFLOW dewatering model
predicts that the tailings would drain down nonlinearly through time reaching an average saturated
thickness of 3.5 feet (1.07 m) after 10 years of dewatering.” These two conclusions are not compatible. As
part of this Response to Interrogatory, the results of the dewatering analyses need to be considered in
conjunction with the settlement analyses and the subsequent assessment of cover settlement.
As stated previously, no explicit discussion or analyses were provided regarding any tailings
management/disposal process-related differences such as different tailings placement methods/modes that
may have occurred/might exist with regard to the various tailings disposal cells or of the effects that such
differences might have on tailings consolidation and settlement behavior in each disposal cell area.
Additionally, no discussion or analyses were provided for differences in dewatering system designs,
differences in the expected dewatering efficiencies likely to occur between different cells (with resulting
differences in statured tailings thicknesses at the different stages in time evaluated in the settlement
analyses), or differences in thicknesses of tailings in the different cells.
In summary, based on review of all of the above, the Division concludes that the analyses provided by
EFR are, in general, overly simplistic and do not adequately account for the full range of different
conditions that may occur with the tailings management cells area. Extrapolating assumed tailings
parameters and properties from published data on tailings at other facilities creates additional
uncertainties in the consolidation, settlement, stability, and liquefaction analyses. Assumed data must be
supplemented by site-specific data; alternatively, the most reasonably conservative values might be used
if adequate assessment and justification is provided. Justifications for some parameter values are lacking
in EFR’s response. EFR should provide additional analyses that specifically address the different factors
and conditions and their effects referenced in the preceding paragraphs. Also, there appears to be several
errors, omissions, discrepancies, and insufficient information in the analyses conducted and provided by
EFR which need to be to be addressed before appropriate and reliable conclusions can be reached.

Response:

EFRI conducted a tailings investigation of Cells 2 and 3 at the White Mesa Mill site in
October 2013 to address the Division’s comment for this interrogatory and Interrogatory
09/1 requesting collection of site-specific tailings data to supplement existing tailings
data used settlement analyses. Results are presented in MWH (2015b). Settlement
analyses have been updated to incorporate the additional site-specific tailings data, as
well as the revised cover grading design, results of the recent site-specific probabilistic
hazard analysis (presented in MWH, 2015a), and revised procedures for the seismic
settlement analysis. The revised analyses are provided in Attachment E, Settlement
and Liquefaction Analyses, and will be included in the next version of the Updated
Tailing Cover Design Report (Appendix D to the Reclamation Plan).

These revisions address the Division’s comments which include requests for (1)
collection of site-specific tailings data to supplement exiting tailings data, (2) use of site-
specific tailings data to evaluate settlement, (3) inclusion of all layers into the settlement
analyses, (4) revisions to seismic settlement calculations, and (5) revisions to differential
settlement calculations. To evaluate changes in settlement and water levels due to
dewatering and placement of final cover prior to and after final cover placement, EFRI
will conduct settlement monitoring and install mini-piezometers across the cells prior to
the first phase of cover placement. This data will provide information on the rate and
extent of dewatering of the cells and settlement to confirm when the final phase of cover
can be placed and when active maintenance is no longer required.

Evaluation of total settlement due to final cover placement and dewatering indicates
potential future settlement during active maintenance of approximately 0.9 to 1.6 feet for
Cells 2 and 3. During this time, additional fill can be placed in any low areas in order to
maintain positive drainage of the cover surface. The total estimated settlement that
could occur (due to creep and seismic settlement) after the maintenance time period is
estimated to range from 0.3 to 0.7 feet. This estimated differential settlement is
sufficiently low that ponding or slope reversal is not expected to occur on a cover slope
of 0.5 to 1.0 percent. The results of the settlement analyses also indicate that cover
cracking of the highly compacted radon barrier is not expected.

Similar results are expected for Cells 4A and 4B. Although Cells 4A and 4B have higher
tailings thicknesses, these cells have a more effective dewatering systems and a low
water level requirement for dewatering. These cells also have a slightly steeper average
cover slope (approximately 0.8 percent) than Cells 2 and 3.

TECHNICAL ANALYSIS – EROSION STABILITY ANALYSIS

The revised calculated 1-hr and 6-hr duration PMP values are equal to or smaller in magnitude than the
respective PMP values previously determined (8.3 inches and 10.0 inches, respectively) using the method
of Hansen et al. 1984. The existing design is, thus, oversized relative to precipitation projected to occur at
the site. Therefore, the previous analyses are considered acceptable and bounding.
Review of the topslope erosional stability calculations indicates that these analyses are not complete and
that the validity of certain assumptions used in these calculations has not been adequately demonstrated.
Missing from these analyses, for example, are a sensitivity analysis case of bare soil conditions occurring
on soil-only topslope surfaces (e.g., “uniform weathered earth” or bare soil condition) to simulate a lack
of vegetation on these topslope areas, and a full analysis and justification for the estimated Manning’s
“n” values appropriate for the soil-only surfaces, and gravel/soil admixture surfaces. For example, the
response did not distinguish between an appropriate “n” value for uniform weathered earth conditions
and “n” values for vegetated conditions; e.g., n = ( nR2 + nS2 + nΨ2 – [0.0156] )½ (Temple et al. 1987, p.
5).
Additionally, in the erosion analyses, EFR assumed a default flow concentration factor of 3, in
accordance with recommendations in NUREG-1623 (NRC 2002). However, this assumption is valid only
if uniform grading will be done during construction and differential settlement has been shown to be
insignificant. As discussed in Section 3.3 above regarding the Response to Rd 1 Interrogatory 03/1 and in
Section 7.0 regarding the Response to Rd 1 Interrogatory 07/1, neither the ability to construct the
proposed flat topslope areas to a uniform slope nor the potential for differential settlement to occur in the
tailings management area embankment after closure have been adequately demonstrated.
The EFR response and calculations and methodologies relating to sizing of angular and rounded riprap
on the different sideslopes of the tailings cells area are considered acceptable.
The EFR response, calculations, and methodologies relating to evaluation of the filter gradation criteria
are considered acceptable.
EFR committed to, but did not provide revised Drawings, revised CQA/CQC Plan, and revised Technical
Specifications showing the filter and rock riprap layers. These revised documents will need to be
reviewed, when available, to verify that these changes have been made. Because these revised documents
were not submitted in its interrogatory response, this interrogatory will remain open.

Based on the results of the plant survey conducted by EFRI in 2012 and evaluation of
the plant cover performance at the Monticello site (which has similar environmental
conditions), a plant cover estimate of 30 percent was determined to be a reasonable
value for reduced performance (drought) conditions, rather than bare soil conditions.
See Attachment G for further discussion. This value was used for the erosional stability
analyses to represent long-term, lower-bound vegetation conditions.

NRC (2002) states that a concentration factor is used in the erosional stability
calculations to account for imperfections in the slope (NRC, 2002). As noted in NRC
(2002), the addition of a concentration factor is based on studies performed by Abt and
Johnson (1991) which recommend a factor of 2 to 3. NRC (2002) recommends a default
value of 3 for the concentration factor. Review of the Abt and Johnson (1991) study and
follow up discussion with Steve Abt (Abt, 2012) confirm that the concentration factor
included in the erosional stability calculations in NRC (2002) is intended to account for
imperfections in the slope, and concentration and channelization of flow on the surface.
Steve Abt (2012) also confirmed the recommendation of a concentration factor of 2 to 3
for cover slopes on uranium disposal facilities based on the Abt and Johnson (1991)
study. The concentration factor of 3 presented in NRC (2002) was used in the analyses,
and is applicable to the planned sequence of tailings settlement, monitoring, and cover
placement.

The revised Drawings, Technical Specifications, and CQA/CQC Plan incorporated the
results of the revised erosional stability analysis and the documents are provided in
Attachments B, C.1, and C.2, respectively, for Division review.

LIQUEFACTION

In the Rd 1 interrogatory, EFR was requested to “provide revised liquefaction analyses that rely upon
actual site-specific data for the tailings materials, rather than assumed parameters." EFR’s response to
this Interrogatory states that "a constant Standard Penetration Test (SPT) blow count (n-value) of 2
blows in 12 inches (uncorrected) is assumed for the tailings zones that will remain saturated under long-
term steady state conditions." While this assumption of 2 blows in 12 inches (uncorrected) is a
conservative reinterpretation of the previously assumed value of 4 blows in 12 inches, it is still only an
assumption; it is not based on data. It is again requested that site-specific data for the materials be used
in analyses, not assumed data. Alternatively, EFR should use, and provide adequate justification for
demonstrating that the most reasonably conservative parameter values possible (are used) in all
calculations.
The assumed SPT blowcounts are subsequently corrected using a fines content of 30, said to be based on
an average of laboratory test values. Sands with this large of fines content are typically quite resistant to
liquefaction (hence the much greater blow counts after the fines correction). Since the fines content value
used to characterize the tailings is based on an average value (and given that the effect of fines content on
liquefaction resistance is not linear), it is more appropriate to use a lower bound estimate of fines content
rather than average value; otherwise, a false factor of safety may result for some of the coarser-grained
materials. Again, as stated in the previous interrogatory, consideration should be given to the potential
variation of properties of the tailings.
The liquefaction analyses presented in Attachment F use a peak ground acceleration of 0.15 g and a
moment magnitude of 6.0. These values are consistent with those of revised probabilistic seismic hazard
analyses. However, as part of the earlier deterministic analysis, Tetra Tech (2010) estimated a magnitude
6.3 for a random background event, said to be consistent with that used in previous seismic evaluations
performed for sites in the Colorado plateau. Please clearly identify and justify the more appropriate
value to use in the analyses, and revise analyses as needed.
The liquefaction analyses presented in Attachment F uses a dry unit weight of tailings of 90 pcf. Page C-4
of the REC plan (Denison Mines 2011) indicates that the dry unit weight of the tailings is 91.4 pcf, rather
than 90 pcf. The dry unit weight of tailings used in the settlement analyses in Attachment E appears be
86.3 pcf. In the previous Interrogatory, it was stated that “consistent characterization of the tailings
throughout the report seems to be needed.” This issue remains unaddressed.
In the simplified liquefaction analysis procedure, the parameter Kσ which accounts for effects of confining
stress is not used. At the base of the tailings, the currently computed effective vertical overburden stress is
nearly two tons per square foot. At this value, Figure 14 of Youd et al. (2001) shows the value of Kσ for
sands to be about 0.81, which would tend to reduce the as-calculated factor of safety. The factors of
safety should be recalculated including the correction factor Kσ, or alternatively exclusion of this factor
from analysis should be justified.
In the liquefaction analysis presented in the revised Attachment F, there appears to be multiple
inconsistencies regarding the thicknesses of the various components of the cover system for each of the
cells (and hence the stresses used in the analysis may be incorrect). Normal stresses calculated in the
liquefaction analysis sheet are associated with assumed cover-system soil thicknesses, which appear in
some instances to be too high, as well as with assumed relative compactions, some of which are too high.
For example, the thickness of random fill material at 95% of Standard Proctor dry density in the cover is
stated in the liquefaction analysis to be 4.7 feet for Cell 2. This appears to be too thick. Therefore, the
August 31, 2015
Division’s Assessment of EFR Responses to Rd 1 Interrogatory White Mesa Rec Plan 5.0;
R313-24-4; 10CFR40, Appendix A, Criterion 1; INT 09/1; Liquefaction Page 25 of 60
results of the liquefaction analysis itself, which depend on the "compacted cover" thickness, apparently
are in error. The entire design cover system in the liquefaction analysis, from top to bottom, is claimed in
the liquefaction sheet to be as follows:
Topsoil rock mulch: 0.5 feet thick.
Random fill at 85% of Standard Proctor dry density: 3.5 feet
Random fill at 95% of Standard Proctor dry density: 4.7 feet
Grading fill at 80% of Standard Proctor dry density: 2.5 feet
The assertion that the value of 4.7 feet appears to be too high for the random fill at 95% of Standard
Proctor dry density can be demonstrated from a number of sources. Figure 2.2 in the Revised ICTM
Report (Denison Mines 2010) provides a "generalized" cross-sectional view of the cover system for the
site and gives the purported general cover design is as follows:
Topsoil rock mulch: 0.5 feet thick.
Random fill at 85% of Standard Proctor dry density: 3.5 feet
Random fill at 95% of Standard Proctor dry density: 2.8 feet
Grading fill at 80% of Standard Proctor dry density: 2.5 feet
The random fill at 95% of Standard Proctor dry density has a thickness listed above of only 2.8 feet, not
4.7 feet. The REC plan (Denison Mines 2011) offers similar information, but with the thickness of random
fill at 95% of Standard Proctor dry density being said to be only 2.5 feet. However, this generalized
cross-sectional view of the cover system also is considerably different compared to plans for actual
constructed thicknesses in Cells 2 and 3. To obtain a more accurate value for planned thickness of
random fill at 95% of Standard Proctor dry density, it is necessary to turn to the engineering drawings. A
check can be made of the value used in the liquefaction analysis by comparing it against "compacted
cover" values shown for Cell 2 in Sheet TRC-7 of the REC Plan, Revision 5.0 (Denison Mines 2011).
Sheet TRC-7 is titled, "Cover over Cell 2 Cross Sections." These cross sections of the planned Cell 2
cover system show a maximum thickness for the "compacted cover", representing the random fill at 95%
of Standard Proctor dry density, of about two feet. However, that exists only in a few places. Cross
Section A shows only about 40% of the cell along that cross-sectional line having any "compacted cover"
whatsoever, with an average thickness of only about one foot where that "compacted cover" does exist.
About 60% of the cell along Cross Section A has no cover of 95% of Standard Proctor dry density at all.
Cross Section B shows only about 25% of the cell along that cross-sectional line having any "compacted
cover" of 95% of Standard Proctor dry density whatsoever, with an average thickness of about one foot
where the compacted soil does exist. 75% of the cell along that cross section has no "compacted cover" of
95% of Standard Proctor dry density at all. Cross Section C shows only about 25% of the cell along that
cross-sectional line having any "compacted cover" of 95% of Standard Proctor dry density whatsoever,
with an average thickness of one foot or less where the "compacted cover" exists. Sheet TRC-2 also
confirms this, but in plan view. Cross Section C shows about 75% of the cell along that cross-sectional
line with no cover having 95% of Standard Proctor dry density at all.
Assuming that the cross-sections provide a representative cross-sectional view of the cover system in Cell
2, it appears that, on average, to a rough approximation (assuming that each cross-section represents
one-third of the cover), coverage of the cell by any 95%-of-Standard-Proctor "compacted cover" at all
exists on only a little more than [(0.333)(0.40) + (0.333)(0.25) + (0.333)(0.25)] = 0.3, or three-tenths
(3/10), of the cell. The average thickness of "compacted cover" at the cell, averaged over the cell's entire
area, is thus only about (0.3)(1 ft) = 0.3 ft.
The liquefaction analysis sheet uses a value for the thickness of "compacted cover" having 95% of
Standard Proctor dry density that happens to be [(4.7 – 0.3)/0.3] x 100% = 1470% in excess of the actual
August 31, 2015

R313-24-4; 10CFR40, Appendix A, Criterion 1; INT 09/1; Liquefaction Page 26 of 60
value. In other words, the thickness of the random fill at 95% of Standard Proctor dry density assumed in
liquefaction analysis is 15.7 times that value. Please address these inconsistencies in the liquefaction
analysis spreadsheet calculations and provide correct values for the thickness of the random fill at 95%
of Standard Proctor dry density.
Apart from issues associated with characterization of the cover system components, the liquefaction
analysis spreadsheet calculations presented in Attachment F indicated a tailings surface elevation for
Cell 2 of 5613.5 feet. 5613.5 feet is the approximate surface elevation for much of the tailings in Cell 2.
However, tailings in the vicinity of Cross Section C in Cell 2 have much higher elevations in the northern
half of the cell. There, the elevations reach to 5623 feet. Also, the liquefaction analysis spreadsheet
calculation shows that the water surface elevation for Cell 2 is 5593.03 ft amsl. For of the second quarter
of 2012, on May 29th, the reported depth to water in the tailings slimes in Cell 2 was measured as 21.10
ft (EFR 2012). The top of slimes drain pipe is at an elevation of 5618.73 ft amsl (personal communication
with Russ Topham of the Division on October 5, 2012, who reported receiving it from Garrin Palmer of
EFR on October 5, 2012). So, the calculated head of water in the tailings is estimated to be 5618.73 ft
amsl minus 21.10 ft, or 5597.63 ft amsl. This is 4.6 feet higher than what is shown in the liquefaction
analysis sheet. These values should be corrected.
As is the case for Cell 2, so it is for Cell 3 that actual planned thicknesses of various layers at different
percentages of Standard Proctor dry densities, or at different compactions, greatly vary from what the
liquefaction sheet shows. Sheet TRC-6 in the REC Plan (Denison Mines 2011) demonstrates this. Please
fix the stated thickness values. Also, since the errors in thicknesses translate to errors in calculated
normal stresses induced by cover systems in the various cells, and other calculations on the liquefaction
analysis sheet, please be sure that these are fixed as well.
The liquefaction analysis spreadsheet calculations identify the tailings thickness for Cell 2 as 32.5 feet,
that for Cell 3 as 38.5 feet, and that for Cells 4A/B as 40.5 feet. Table F.1 of Denison Mines 2011 is cited.
Table F.1 and the Attachment F-2, Settlement Analysis spreadsheets in Denison Mines 2011 likewise
provide figures of 32.5, 38.5 and 40.5 feet for the tailings thicknesses for Cells 2, 3, and 4A/B,
respectively. These figures, however, appear to conflict with the tailings thickness for Cells 2 and 3 given
on Page C-2 of the Response text of "approximately 30 feet" and "the tailings thickness for Cells 4A/B of
approximately 42 feet" (Denison Mines, 2011). These inconsistencies should be fixed.
It can be seen, based on 1980 as-built drawing information from Energy Fuels Nuclear, Inc., as shown on
Sheet TRC-7 of Denison Mines (2011) that, for most of the Cell 2, the elevation of the tailings surface is
5613 ft amsl. This knowledge, coupled with some additional information, can lead to a better
understanding of maximum saturated thickness in the tailings of Cell 2. Assuming for the moment that the
Denison Mines (2011) Table F.1 32.5 feet value is correct, this means that the nominal base of the
tailings must be, on average, at about 5613 ft amsl minus 32.5 feet, or 5580.5 ft amsl. Since, as calculated
above, the head of water in the tailings is 5597.63 ft amsl, it follows that the average saturated thickness
of the tailings in Cell 2 is 5597.63 ft amsl minus 5580.5 ft amsl, or 17.1 feet. This compares with a value
of 12.03 feet claimed for maximum saturated thickness in the liquefaction sheet. The latter number
appears to be off by 5.07 feet, which would be a 30% error. This may substantively change a number of
liquefaction calculations. Please correct the saturated thickness in the liquefaction sheet.
From the previous calculations for Cell 2, it is observed that the saturated thickness is about 30%
greater than claimed in the liquefaction analysis. This has effects on calculations for effective overburden
stress and other consequent calculations. These effects can be accounted for to some extent. The
saturated zone starts about 4.5 feet higher than shown on the liquefaction analysis sheet, at
approximately 5597.63 ft amsl, not at 5593.03 ft amsl. This means that 4.6 feet of tailings must be
accounted for with a 120.3 pcf saturated specific weight compared to old approach of (if that 4.6 feet of
tailings is assumed to have a moist specific weight of 95.40 pcf). Secondly, it changes the values of
effective stress at each deeper depth analyzed, since it also shifts the elevation vs. water pressure curve

up. The Division request that EFR please make appropriate changes to the effective overburden stress
calculations, or justify not doing so, not only for Cell 2, but for other cells, as needed.
In summary, based on a review of the information provided and in consideration of the issues previously
discussed, the Division finds that several of the issues identified in the Interrogatory remain unaddressed,
and consequently, the Division is unable to assess the correctness of EFR’s conclusions regarding
performance of the tailings impoundment cells relative to liquefaction. In particular, no explicit
discussion relating the results of the tailings dewatering analysis to the water levels used in the
liquefaction analyses was presented. Also, parameters regarding the tailings characterization continue to
be assumed (although now some are more conservatively selected) rather than being based on site-
specific data. If assumed data are used, it should reflect the most reasonably conservative values
possible. While adverse performance seems unlikely based on the relatively high factors of safety with
respect to liquefaction potential currently calculated, there are enough inconsistencies in the analyses
that further evaluation is merited.

Response:

EFRI conducted a tailings investigation of Cells 2 and 3 in October 2013 at the White
Mesa Mill site to address the Division’s comment for this interrogatory and Interrogatory
07/1 requesting collection of site-specific tailings data to supplement existing tailings
data used settlement analyses. The results are presented in MWH (2015b).
Liquefaction analyses have been revised to incorporate the additional site-specific
tailings data, as well as the revised cover grading design, results of the recent site-
specific probabilistic hazard analysis (presented in MWH, 2015a), and revised
procedures for the liquefaction analysis. The revised analyses are provided in
Attachment E, Settlement and Liquefaction Analyses, and will be included in the next
version of the Updated Tailing Cover Design Report (Appendix D to the Reclamation
Plan).

These revisions address the Divisions comments which include requests for (1)
collection of site-specific tailings data to supplement exiting tailings data, (2) use of site-
specific tailings data to evaluate liquefaction, (3) include use of results for most recent
PSHA completed for the site (MWH, 2015a), and (4) revisions to liquefaction
calculations and assumptions.

The results of the liquefaction analyses indicate the tailings are not susceptible to
earthquake-induced liquefaction for reclaimed conditions.

TECHNICAL ANALYSES – FROST PENETRATION ANALYSIS

The May 31, 2012 EFR response and calculations and methodologies used for completing the revised
frost depth analysis are considered acceptable, with the one exception described in the following
paragraph.
The Division notes that in the revised infiltration and revised radon emanation modeling most recently
completed by EFR, use of NRC-recommended adjusted porosity and bulk density values was not
considered. The Division requests that EFR conduct a revised radon emanation modeling sensitivity
analysis (as well as conduct a revised infiltration sensitivity analysis) for the approved final cover for a
scenario that incorporates adjusted bulk density and porosity values (or adjusted appropriate other soil
parameters in the infiltration analysis) for soils in the upper zone of the cover system potentially impacted
by the predicted maximum frost penetration. Adjusted soil property values used in the simulations should
either consist of adjusted values derived in a manner consistent with NRC recommendations for adjusting
such properties in frost-impacted soils for radon flux emanation calculations (NRC 2003a, Section 5.1.3),
or adjusted values derived/assigned in manner consistent with recommendations provided in Benson et
al. 2011, whichever is more conservative for the respective simulations. (See also discussion in Section
1.3 of the Technical Memorandum, White Mesa Mill Site – Revised ICTM Report Review addressing
EFR’s Response to Rd 1 Interrogatory 01/1 on the Revised Infiltration and Contaminant Transport
Modeling Report).
The final revised Appendix B to Appendix D will need to be reviewed, when available, to verify that the
revised frost depth information has been incorporated. The final revised frost depth analysis completed
once the final cover design has been approved Drawings will need to be reviewed, when available, to
verify that the revised frost depth calculation has addressed elements included in this request and has
appropriately addressed any changes in the cover design, as applicable. Because these revised documents
were not submitted with the response, this interrogatory will remain open.

Response:

A workshop on April 30, 2013 with representatives from the DRC, DRC’s contractor
(URS), EFRI, MWH, and Dr. Craig Benson facilitated discussion on DRC’s February
2013 review comments on the Reclamation Plan, Revision 5.0 (DRC, 2013b) and the
revised Infiltration and Contaminant Transport (ICTM) Report (DRC, 2013a). During this
meeting, Dr. Benson presented material properties for the proposed cover materials for
White Mesa and compared this data to the range of design recommendations provided
in NUREG/CR-7028 (Benson et al., 2011) and the database of pedogenic-altered values
at the Alternative Cover Assessment Program (ACAP) sites. Discussion from this
meeting is provided in the August 2015 EFRI response document to DRC’s 2013 review
comments on the ICTM (see response to Interrogatory 01/1 - Inconsistencies Between
Revised ICTM Report and Reclamation Plan Rev 5.0). The hydraulic test results for the
soils stockpiled at White Mesa are within the range of parameter values anticipated to
occur long-term as noted by Benson et al. (2011). Based on this comparison, adjusting
soil characteristics due to frost penetration or other potential pedogenic processes are
not warranted. The physical and hydraulic properties of the relatively permeable cover
soils at the emplaced conditions are close to long-term properties from pedogenic
processes, are such that post-construction changes should be minimal.

The frost penetration analysis will be updated after approval of the conceptual final cover
design is obtained from the Division. The frost penetration analysis requires revision to
incorporate additional data collected from a site investigation conducted on April 19,
2012 to further evaluate cover borrow materials. It is anticipated that the results of the
updated analyses will be similar to the analyses presented in Denison (2012), with a
frost penetration depth on the order of 81 cm (32 in).

MESA RECPLAN REV. 5.0; R313-24-4; 10CFR40, APPENDIX A; INT 11/1; VEGETATION AND
BIOINTRUSION EVALUATION AND REVEGETATION PLAN

The Division finds that EFR has addressed, in part, the items included in the interrogatory and
considerable useful new information has been provided. However, some additional information is still
needed to complete the responses, as described in the following paragraphs.
EFR presented results of the vegetation survey in summary fashion and provided few details. Are there
survey reports describing methods and results in greater detail? Is there data available for each transect
location? Is there information on other plant species observed but that did not have cover recorded at the
transect points? The vegetation survey results did not include an updated vegetation map or information
on the current vegetation in the reclamation cells. The map in the September 2011 Reclamation Plan
(Revision 5.0) is clearly inconsistent with the results of the vegetation sampling reported in the August 15,
2012 Responses to Interrogatories, in that 19.1% big sagebrush cover was found at sample sites that are
located in areas shown in Figure 17-1 as reseeded grassland and controlled big sagebrush. Information
should have been provided on the current vegetation of the reclamation cells. The information provided
does not provide an adequate account of current vegetation or an explanation of the successional
processes that have occurred following previous disturbances and reclamation efforts.
Attachment G provides an updated seed mix, which now includes galleta. The total seeding rate in Table
D.1 needs to be corrected to be 22.5 lbs PLS/acre. A column of PLS/square foot should be added to this
table (this information was previously provided for most species in the September 2011 Appendix J
Reclamation Plan). This mix is now correctly characterized as containing both native and introduced
species.
Information was provided on the ecological characteristics of each of the species in the seed mix.
However, no information was provided regarding past success or failure with these species at the site
during interim reclamation. Previous revegetation experience at the site and changes in composition and
cover over time, if available, need to be presented in order to support the predicted cover percentages.
Table D.4. Please provide more explanation as to how the values in this table were derived.
Table D.9 provides levels of soil properties for stockpiled soils compared to sustainable levels reported in
the literature. These “sustainable levels” may or may not be achievable or sustainable over a long term
within the study area, depending on its environment. To help determine realistic long-term expectations,
soil properties should also be measured at reference areas. To what extent will establishment of
grassland vegetation contribute to developing soil properties supporting sustainable vegetation?
The description of organic matter and nutrient amendments lacks sufficient detail. Provide more
information regarding quantities, potential sources, and suitability for sustained growth?
How will institutional control be used to exclude grazing by livestock for the performance period?
Weeds and weed management should be addressed. It is noted that a significant portion of the vegetation
over in the sagebrush areas surrounding the White Mesa Mill Site comes from cheatgrass and Russian
thistle, and that cheatgrass and jointed goat grass initially dominated revegetation areas at Monticello..
What other weeds occur in the area or may occur in the future? Use of a mix of hay and manure to
provide soil organic matter could introduce weeds.
Section D.4.5. of Attachment G , Supporting Documentation for (Rd 1) Interrogatory 11/1 (Revised
Appendix D to the Updated Tailings Cover Design Report ), first sentence indicates that “monitoring of
an alternative cover at the Monticello Mill Tailings Disposal Site showed that the plant cover performed
well over a seven year period.” The last phrase “plant cover performed well over a seven year period”
August 31, 2015

should be reworded because although cover goals for grasses were met later in the 7-year period, cover
goals established for the Monticello cover for shrubs species were not achieved despite significant shrub
planting efforts in in 2000 and in 2007 (e.g., see Sheader and Kastens [undated] circa 2007). Please
provide a reference for the statement that eight species provided 70% of the plant cover at Monticello.
The text in Revised Appendix D does not provide an indication of the percentage vegetative cover
comprised by weedy species including weedy cheatgrass and Russian Thistle over that time period at
Monticello and does not discuss how these species may affect cover revegetation goals
(evapotranspiration capabilities) established for the Monticello or White Mesa cover systems.
Section D.7.2 addresses succession, including increase in sagebrush cover. The discussion should
acknowledge the establishment of big sagebrush and other shrubs on former seeded grassland and
controlled sagebrush areas north of the Mill Site in the 35 years since the original vegetation study, and
discuss its relevance to the revegetation plan. The discussion indicates that warm season grasses are
expected to increase over time. Is there an existing vegetation community in the region similar to that
which is expected to develop? The discussion also mentions pulse-dominated precipitation – are there
expected changes in seasonality of precipitation? An explanation should be provided as to why shrub
species that occur just south of, and at lower elevations than the tailings management areas location, ,
such as four-wing saltbush, shadscale, blackbrush, and Mormon tea, would not increase under potentially
warmer and dryer future climate conditions at the site.
The Reclamation Plan (or revised Infiltration and Contaminant Transport Report) needs to provide: (1)
definition of clear, concise, and measurable revegetation acceptance goals/criteria for the vegetation
establishment on the tailings cell cover system, (2) a description of how EFR will conduct periodic post-
closure monitoring and reporting to the Division of the vegetation community health, viability, success,
and sustainability, (3) a description of proposed action plans, schedules and deadlines for remedial
actions if/when needed to effectuate plant community success, and (4) similar follow-up monitoring of the
plant community/cover system to ensure successful performance before release of the facility’s surety
bond and/or transfer of title to DOE. EFR should describe specific, quantitative goals for shrub
establishment (including rooting depths and minimum acceptable shrub cover percentages) that consider
the need for deeper rooted plants to remove water that may accumulate lower in the cover profile in
response to an exceptionally wet year or successive wet years, especially given the lack of a capillary
break layer in the currently proposed cover design. In developing these descriptions, plans, and goals,
EFR should consider and address lessons learned from the post-closure monitoring and maintenance
activities and/or corrective revegetation measures required at the Monticello, Utah tailings repository
and other similar facilities in this regard (e.g., Waugh 2008; Sheader and Kastens undated, circa 2007;
U.S. DOE 2007; Sheader and Kastens [undated, circa 2007). EFR should assess the potential
applicability and benefits of using vegetation health monitoring tools/metrics such as the Cover
Vegetation Index recently implemented at the Monticello Repository (U.S. DOE 2009).
The Reclamation Plan should describe corrective measures that may be needed to address/correct issues
related to: (1) establishment of undesirable species, e.g., colonization by certain undesired grass/weedy
species that may have more limited water stress tolerance than initially seeded grass species and/or that
may outcompete planted grass species unless controlled (e.g., Smesrud et al. 2012; Sheader and Kastens
[undated, circa 2007]); (2) Seed predation following seeding/reseeding efforts; (3)Possible low success
rates resulting from for shrub establishment efforts, etc…. Estimated costs for conducting these post-
closure activities, corrective actions, and reporting, once approved by the Division, will need to be
incorporated in the financial surety estimate.
The Revised Attachment G provided by EFR as part of its Response presents the results of a June 1012
burrowing animal survey (Section D.5.3). However, as described above, the results are presented in
summary fashion and few of the necessary details are provided. Are there survey reports describing
methods and results in greater detail? Is there data available for each transect location? Does badger

burrow density include feeding areas (dug-out prey burrows)? The reported burrow density for badger
appears very low. Additional information about potential burrow densities should be provided based on a
review of the literature. The analysis should consider both burrows dug by badgers for their own use and
digging while hunting.
Little information is presented on burrow densities, other than Gunnison prairie dog. Results for
Gunnison prairie dog are based on the June 2012 survey and do not consider literature values.
Information on burrow densities for Gunnison prairie dog should be summarized by transect and the
locations of prairie dog towns marked on a map. The results need to be put in context by reference to
literature, for example Lupis et al. 2007, considering both regional densities, predicted range and habitat
suitability. The statement in Attachment D that prairie dogs are unlikely to occur because they prefer low
plant cover and short vegetation is not consistent with the description of habitats where they occur in
southeastern Utah in Lupis et al. 2007. Most of the grass species included in the seed mix are reported to
occur in grassland habitat occupied by this species in southeastern Utah. They also occupy desert shrub
habitats.
Table D.8. Ranges of depths for burrowing mammals mostly not provided, just maximum depth, and
based on a single citation per species. The “maximum” depth for Gunnison’s prairie dog of 122 cm from
Verdolin et al 2008 should be correctly characterized as an average depth reported from several studies.
The actual maximum (mean plus 1 SD) reported by Verdolin et al. 2008 appears to be 1.85 m. All of the
numbers in this table should be revisited to provide a range of maximum values reported in the literature
and to determine whether the maximum has been accurately stated.
Table D.6 and discussion. There is literature indicating that big sagebrush can root to depths
considerably below 180 cm. Please address and further explain this finding/statement. Rooting depths of
other shrubs that may occur should also be considered.
Additional information needs to be presented to justify that the highly compacted zone will minimize
biointrusion by plant roots. Consider moisture conditions, potential degradation when dry, behavior of
roots related to soil moisture and gas exchange, and other factors. Cite previous studies or observations
of root growth relative to compacted soils.

Response:

Vegetation on previously revegetated areas at the Mill site has not been evaluated. This
information would have limited value in evaluating the proposed reclamation plan or in
determining if future reclamation will produce a sustainable plant community on the
tailings cells. The proposed reclamation plan is substantially different than previous
reclamation efforts in terms of soil cover, soil amendments and species to be planted,
such that any comparisons would not provide any predictive value. The only reclamation
that has occurred at the Mill site was seeding of Cell 2 in 2011. Seeding only included
crested wheatgrass (Agropyron desertorum) and no evaluations have been conducted
since seeding occurred.

Further details of the 2012 vegetation survey are provided in a revision of Appendix D
(Vegetation and Biointrusion Evaluation) to the Updated Tailings Cover Design Report
(Appendix D of the Reclamation Plan, Revision 5.0). The revised Vegetation and
Bionintrusion Evaluation appendix is provided as Attachment G.1 to this response
document.

A map of current vegetation at the Mill site does not exist. The most recent mapping of
vegetation at the Mill site was conducted by Dames and Moore in 1977 (Dames and

Moore, 1978) as part of the Environmental Report for the White Mesa Uranium Project.
Further discussion of mapping units from 1977 and the 2012 survey is presented in
Attachment G.1.

An updated seed mixture that includes number of seeds/square foot and the addition of
shrub species is presented in Attachment C.1, Attachment G.1, and Attachment G.2.
Attachment C.1 is revised Technical Specifications to the Reclamation Plan, Revision
5.0. Attachment G.1 is as described previously. Attachment G.2 is a revised Appendix J
(Revegetation Plan) to the Updated Cover Design Report (Appendix D of the
Reclamation Plan, Revision 5.0).

The species in the proposed seed mixture have not been used on site, so there is no
information available regarding success or failure with these species at the site during
interim reclamation efforts. However, there are decades of revegetation research using
these species in semiarid regions of the western U.S. along with tens of thousands of
acres that have been successfully reclaimed with these species. The plethora of
information that exist on the use of these species for disturbed land reclamation provides
ample evidence that these species are adapted to the environmental conditions of the
Mill site and are highly likely to lead to successful reclamation. As stated above, the only
reclamation that has occurred at the Mill site was seeding of Cell 2 in 2011 with crested
wheatgrass, and no evaluations have been conducted since seeding occurred.
Further explanation of LAI values and how numbers were derived are presented in
Attachment G.1.
No reference areas have been previously established to provide information on soil
properties to document that sustainable levels are achievable. However, soil that will be
used as cover material on the tailings cells has been evaluated, and was included in
Attachment G of EFRI (2012) as Table D.9 (EFRI, 2012). An update of this table is
included as Table D.38 in Attachment G.1 to this response document. This table
includes physical and chemical properties of the soil and also levels reported in the
literature that would be considered sustainable. Soil properties that appear deficient and
would need improvement to achieve sustainability include: percent organic matter, total
nitrogen, and extractable potassium. Amendments would be applied during reclamation
to address these deficiencies and this application is discussed Attachment G.1. Over
time, the soil-forming process of pedogenesis will continue as climate and on-site
organisms (primarily plants and the soil microbial community) modify the soil over time.
This process would include the addition of organic matter in the form of composted
biosolids which will improve soil structure, water holding capacity, cation exchange
capacity, buffering capacity, and overall soil fertility. All of the benefits will lead to a
more productive soil and greater sustainability.

Further details on the use of an organic amendment including type, rates of application,
source of material, and potential benefits are presented in Attachment G.1. Revised
specifications for soil amendments are provided in Attachment C.1.

Existing restricted fencing of the site will be used as an institutional control to exclude
grazing by livestock for the performance period.

A weed management plan is presented in Attachment C.1 and Attachment G.1.

Cover goals for shrub species have not been met at the Monticello Mill Tailings Disposal
site because of establishment issues related to big sagebrush and seedling damage
caused by montane voles (Microtus montanus) (DOE, 2007). Attachment G.1 reflects
this finding.

The statement that eight of the seeded species at the Monticello Mill Tailings Disposal
site provided 70 percent of the plant cover was based on a progress report from Stoller.
This finding has been modified and discussed further in Attachment G.1 using results
from the 2007 vegetation monitoring report (DOE, 2008).
In the 2007 revegetation monitoring report at Monticello (DOE, 2008) the following was
reported:
“Seed germination requirements for sagebrush and rabbitbrush are potentially
pertinent in determining why these species did not establish well on the
repository cover. Although the seeds of many species (e.g., most grasses)
persist for years in the soil, rabbitbrush and sagebrush seeds persist for only one
season. In addition, sagebrush seed may require cold stratification to germinate.
It is unlikely that the seed was stratified by the supplier prior to shipment, and
seeding was done in April 2000, after natural stratification would have occurred.”
In addition: “In 2000, the 3-month period immediately following seeding was
exceptionally dry, and this may be the major cause of poor sagebrush and rabbitbrush
seed germination. Grass and forb seeds, which persist longer in the soil, would have
emerged later, when conditions were more favorable, and the presence of these seeded
species indicates that this occurred.”
Low precipitation during a critical time of the year following seeding, competition from
more mature vegetation, and damage caused by vole herbivory have been presented as
reasons for low shrub density at Monticello (DOE, 2008; DOE, 2007).
Changes in the relative cover of common weed species at the Monticello site are
summarized from previous monitoring reports (DOE, 2003, DOE, 2004, DOE, 2005a,
DOE, 2005b, , and DOE, 2008) and presented in Table 1. These results demonstrate
that weed species at the site remain well controlled.

The following is taken from DOE (2008): “In Utah, weed law has recently been revised
to reflect categories of weeds targeted for control. The main management goal for
Category C weeds is not to eradicate the weed but to prevent its spread. Small
quantities of Convolvulus arvensis (field bindweed), a Category C noxious weed, have
been observed on the site since 2002, but this species has not spread. One San Juan
County listed noxious weed, Aegilops cylindrica (jointed goatgrass) has been observed
on the site since 2003 in small quantities and also has not spread. Another Category C
noxious weed species, Cirsium arvense (Canada thistle), was observed and treated in
2006, and it has subsequently not been observed. One Category A noxious species,
Centaurea stoebe ssp. micranthos (spotted knapweed) was discovered near the site’s
entrance gate and treated in 2008. Populations of Acroptilon repens (Russian
knapweed), a Category B species, were treated near the office building in 2008. Neither
of these noxious species has spread into the revegetated areas, and they will continue
to be monitored and treated for eradication from the site. DOE will continue to monitor
and manage the entire site, including portions of the site where vegetative success
criteria have been met, for all noxious weed species.”
Based on the success achieved at Monticello in controlling weeds, it is unlikely that the
presence of weeds at the Mill site will negatively affect revegetation goals, and the
proposed weed management plan will help ensure revegetation success.
Attachment G.1 includes modifications to acknowledge the establishment of big
sagebrush and other shrubs on previously seeded grassland and controlled sagebrush
areas north of the Mill site over the last 35 or more years, and a discussion has been
included as to the relevance of this shrub response to the revegetation plan.

There are grassland steppe communities south of Bluff, Utah which is directly south the
Mill site (CARTOKO, 2010). These semiarid grasslands are dominated by a variety of
grama grasses, galleta, three awn (Aristida spp.), ring muhly (Muhlenbergia torreyi), and
pungent muhly (Muhlenbergia pungens) (Banner 1992); all warm-season species.

The discussion of a potential climate shift to a pulse-dominated hydrology has been
deleted (see Attachment G.1). However, in response to the question if there are
expected changes in seasonality of precipitation with a shift to a pulse-dominated
hydrology, we believe there may be a decrease in winter precipitation. Additional
discussion is provided in Attachment G.1.

Regionally common shrub species from areas that are characterized by lower elevation
and having climatic conditions that are warmer and drier than the Mill site would include
fourwing saltbush (Atriplex canescens), shadscale saltbush (Atriplex confertifolia),
blackbrush (Coleogyne ramosissima), and Morman tea (Ephedra viridis).

Fourwing saltbush is one of the most widely distributed and important native shrubs on
rangelands in the western United States including the Intermountain, Great Basin, and
Great Plains regions (Welsh et al., 2003). Fourwing saltbush occurs most commonly in
salt-desert scrub communities in the Great Basin, Mojave and Sonora Desert areas of
western North America (Kearney et al., 1960; Welsh et al., 2003). In the Great Basin
region it is often associated with black greasewood (Sarcobatus vermiculatus), black
brush (Coleogyne ramosissima), big sagebrush (Artemisia tridentata), creosote bush
(Larrea tridentata), rabbitbrush (Chrysothamnus spp.) and shadscale (Atriplex
confertifolia) (Welsh et al., 2003).

Fourwing saltbush is adapted to most soils but is best suited to deep, well-drained;
loamy to sandy to gravely soils. It is very tolerant of saline soil conditions and somewhat
tolerant of sodic soil conditions (Ogle and St. John, 2008).

Shadscale saltbush occurs throughout western North America from California and
Oregon east to North Dakota and south to Arizona and Texas. The greatest
concentrations of shadscale saltbush are found in the Great Basin and Colorado Plateau
(Simonin, 2001). Shadscale saltbush can be found in warm desert shrub-steppe
environments. Populations occur in low valleys, foothills and mesas from 2,500 to 7,500
feet elevation (Simonin, 2001). It often grows in association with other halophytes
including mat-atriplex, and greasewood, but can also be found in sagebrush and pinyon-
juniper communities (McArthur and Monsen, 2004; Welsh et al., 2003). Shadscale
saltbush is highly drought tolerant and is adapted to sites receiving 6 to 12 inches of
annual precipitation. This species is tolerant of high saline conditions (pH 7.5-9.0) and is
classified as a facultative halophyte (Branson et al., 1976). It prefers well-drained soils
but may inhabit a wide range of soil textures from fine to gravelly.

Blackbrush occurs primarily in the transition zones in Great Basin deserts. It is found at
elevations from 2,500 to 7,000 feet in areas where the annual temperature fluctuation
can range from -11 degrees to 116 degrees Fahrenheit. It is drought-deciduous,
meaning that it avoids water stress by becoming temporarily dormant and then shedding
its older leaves as stress intensifies during the dry season. Spiny stems, coupled with
chemical compounds in current year’s growth, protect blackbrush from heavy browsing.
It is adapted to dry and well-drained soils and is most abundant in sandy, gravelly, and
rocky soils.

Green ephedra occurs on rocky or sandy slopes and plains in such plant communities as
the juniper-pinyon woodland, the sagebrush desert, creosotebush deserts, and the
desert grassland from 3,000 to 7,000 feet elevation (Benson and Darrow, 1981).
Common associates include creosotebush (Larrea tridentata), shadscale saltbush,
fourwing saltbush, big sagebrush, galleta, and sand dropseed (Sporobolus cryptandrus).
Green ephedra is tolerant of calcareous, weakly saline, and slightly saline-alkaline
(sodic) sites. It thrives in dry, well-drained sites and it is intolerant of wet sites and poor
drainage. The plant is drought-resistant.

Based on this discussion of ecological characteristics of common shrub species from
sites of lower elevation than the Mill site it is certainly possible that any one of these
shrubs could occur at the Mill site if the future climate was warmer and drier than the
present.

Attachment C.1 and Attachment G.1 include information on revegetation acceptance
goals/criteria that include shrub establishment goals. Lessons learned from post-closure
monitoring at Monticello have been incorporated (see Attachment G.1).

A post-closure monitoring plan has been added and is included in Attachments C.1 and
G.1.

Quantitative goals for sustained shrub establishment are described in Attachment C.1
and Attachment G.1 and include the establishment of a minimum of 500 stems per acre.
Two shrub species, fourwing saltbush and rubber rabbitbrush (Ericameria nauseosa),
have been added to the proposed seed mixture. Both species have the potential for
deep root penetration (e.g. six meters) when soil conditions allow (Kearney et al., 1960)
but are not expected to root into the compacted radon attenuation layer because the
targeted bulk density of the compacted zone of 1.8 g/cm2 will inhibit root penetration
(Mimore et al. 1969; Heilmen, 1981; and Zisa et al., 1980).

There is no further detail on the burrow animal survey that was conducted at the Mill Site
in 2012. Estimates of burrow densities for both badgers and prairie dogs have been
placed in context of literature values in Attachment G.1.
Burrowing depths have been revised and are presented in Attachment G.1.
Rooting depths have been revised and include shrub species and are presented in
Attachment G.1.
Further discussion is presented in Attachment G.1 on soil compaction and root growth.

REPORT RADON BARRIER EFFECTIVENESS

The Division’s assessment of the Response follows below:
As with a number other responses, EFR has deferred final resolution of issues to its submission of the
next revision of the Reclamation Plan. The Division requests that EFR please submit the next revision of
the Reclamation Plan that incorporates all changes proposed in the license amendment request.
EFR’s responses leave unresolved the following issues regarding radon flux modeling:
1. The dependence of Radon emanation and diffusion coefficient on long-term moisture content
(raised in Item d of INT 12/1) is not but should be addressed. Please address this dependence.
[Note: The Division notes that the radon diffusion coefficient used in the revised radon
emanation analysis for the tailings is higher (by about a factor of 3) than the diffusion coefficient
value assumed in radon emanation analyses competed for a similar tailings disposal facility
(Monticello Tailings Repository) in Utah (e.g., NRC 2008). The value used in the Monticello
analysis was derived using a different procedure (Rogers and Nielson 1991) than was used by
EFR. Using a higher radon diffusion coefficient in the radon emanation analysis represents a
more conservative assumption.]
2. The summary of values used for long-term moisture content does not adequately explain the work
presented in Attachment H, Attachment C.2. This lack of supporting interpretation basis leaves
unresolved the conclusion that the values used in Radon modeling are conservative. Please
complete the discussion of values of long-term moisture content used in Radon modeling.
3. Values summarized in Table C-4 for diffusion coefficients are inconsistent with those appearing
in Attachment H, Attachment C.3. Please resolve this inconsistency
4. All calculated Radon fluxes from the surface of the cover system (Layer 5) exceed 20 pCi/cm2-s,
albeit by very slight amounts. Please address the apparent failure of the proposed cover system
design to satisfy the regulatory constraint for Radon flux.

Response:

The radon emanation modeling has been revised to incorporate updated radon diffusion
coefficients and additional site-specific tailings data collected in October 2013 (MWH,
2015). The revised analysis is provided in Attachment H as part of the revised Appendix
C, Radon Emanation Modeling, which will be included in the next version of the Updated
Tailings Cover Design Report (Appendix D to the Reclamation Plan).

The radon emanation coefficients used in the radon emanation analysis were selected
using procedures recommended in NUREG-1620 (NRC, 2003). The radon emanation
coefficient was selected as 0.20 for the tailings based on recommendations in NUREG-
1620 (NRC, 2003) that states a “value of 0.20 may be estimated for the tailings based on
the literature, if supported by limited site-specific measurements.” The radon emanation
coefficient for the cover layers was selected as the conservative default value used in
the RADON model of 0.35.

The diffusion coefficients for the tailings and cover layers for the radon emanation
modeling results provided in EFRI (2012) were calculated based on the empirical
relationship by Rogers and Nielson presented in NRC (1989). This relationship is
dependent upon porosity and the degree of saturation and was based on approximately
100 radon diffusion coefficient measurements. The diffusion coefficients for the tailings
and cover layers have been revised to be calculated using the empirical relationship
presented in Rogers and Nielson (1991). This relationship is an update to the one
presented in NRC (1989) and was developed from over 1,000 radon diffusion coefficient
measurements. The porosity and degree of saturation were calculated based on the
long-term densities and long-term moisture contents presented in Attachment D.

MWH collected representative samples from the on-site random fill and topsoil stockpiles
for use in estimating the long-term moisture contents for the cover layers. The
laboratory results for the 15 bar water contents for these samples were used to estimate
long-term water contents for the random fill and erosion protection layers. NRC (2003)
recommends use of 15 bar water contents to estimate long-term water contents for use
in radon emanation modeling.

The long-term water content of the topsoil was estimated as 5.2 percent based on the
measured 15 bar gravimetric water content for a topsoil sample (E1-A) which represents
the average index properties for the topsoil stockpiles (UWM, 2012). The long-term
water content of the rock mulch was estimated as 4 percent based on the addition of 25
percent gravel by weight to the topsoil.

Based on the cover material gradations, the cover soils were bracketed into three
groups, finer grained soils, uniform graded soils, and broadly graded soils. A weighted
average procedure that accounted for the relative volumes of each soil type (based on
the stockpile volumes) was incorporated to determine the average long-term gravimetric
water content for the random fill using the measured 15 bar water contents. Data used
for estimation of the long-term water content value for the cover material is provided in
Attachment D.

All calculated rates of radon emanation from the surface of the cover system are below
the limit of 20 pCi/m2-sec.

CONCENTRATIONS OF RADIONUCLIDES OTHER THAN RADIUM

To further resolve remaining issues pertaining to concentrations of radionuclides other than radium in
soil, the Division requests that EFR please do the following:
1) Provide justification (either data or references to data) to support EFR’s determination of U-nat
and Th-230 background concentrations.
2) Incorporate a description of how EFR’s site-specific sampling program will be used to determine
background concentrations for radionuclides other than Ra-226 into EFR’s documentation of
how MARSSIM will be implemented and submit for the Division’s review.
3) Incorporate a description of how EFR will use the “sum rules” for surface and subsurface soils
into EFR’s documentation of how MARSSIM will be implemented and submit for the Division’s
review.
4) Incorporate a description of EFR’s plan for using radiation measurement instrumentation for soil
background analyses, radium-gamma correlations, verification data, and sensitivity analyses into
EFR’s documentation of how MARSSIM will be implemented and submit for the Division’s
review.
5) As suggested in Item 4 of INT 13/1, please incorporate into documentation relating to how
MARSSIM will be implemented, descriptions of the following:
 Calibration procedures
 Instrument testing
 Detection limits of sample analyses
 Extent of expected contamination
 Limits of gamma survey
 Verification of the soil-radium gamma correlation

Response:

1) The U-nat and Th-230 background concentrations submitted in earlier
interrogatories (EFRI Round 1 response to 13.2) are solely interim background values,
and will not be used to guide the remediation process.
The mean background data over 24 years of annual sampling from the mill background
sampling station, BHV-3, is 0.78 pCi/g for U-238 and 0.93 pCi/g for Ra-226. These
results are comparable to other background sampling locations off site. Ra-226
concentrations have been reported as 1.1 pCi/g near the airport entrance south of
Blanding, and 0.83 pCi/g southeast of Crescent Junction (Myrick et al., 1981). U-238
values have been reported as 0.94 pCi/g near the airport entrance south of Blanding,
and 0.78 pCi/g U-238 southeast of Crescent Junction (Myrick et al, 1981). These values
are shown in Table 1 below. No comparable Th-230 background data has been found
from the mill’s data or from reference documents.

Background values provided in the earlier interrogatories (1.9 pCi/g U-nat and 0.93 pCi/g
Th-230 based on equilibrium with the Ra-226 value of 0.93 pCi/g) are interim values. No
further investigation is necessary for remediation purposes until background reference
areas are established during the remediation process. A systematic soil sampling
program will be conducted in an area within 3 miles of the site, similar to the areas to be
remediated, to determine the average background radionuclide concentrations to
ultimately be used for the cleanup. Similarity or representativeness will be determined
based on geology, geomorphology, soil type and soil chemistry. The background will be
determined at the beginning of reclamation.
According to MARSSIM 4.5 (NRC, 2000), a site background reference area should have
similar physical, chemical, geological, radiological, and biological characteristics as the
survey unit being evaluated. Background reference areas are normally selected from
non-impacted areas, but are not limited to natural areas undisturbed by human activities.
In some situations, a reference area may be associated with the survey unit being
evaluated, but cannot be potentially contaminated by site activities. For example,
background measurements may be taken from core samples of a building or structure
surface, pavement, or asphalt. The Division will be consulted during selection of
proposed background sample locations.
2) A description of how EFRI’s site-specific sampling program will determine
background concentrations for radionuclides other than Ra-226 has been incorporated
into revised sections of the Reclamation Plan which discuss the implementation of
MARSSIM guidance. Please refer to Section 6.3, and Section 6.3.2 of the revised
Technical Specifications (provided as Attachment C.1 to this document).
3) A description of how EFRI will use the “sum rules” for surface and subsurface
soils has been incorporated into revised sections in the Reclamation Plan which discuss
the implementation of MARSSIM guidance. Please refer to Section 6.6.3.3 of the
revised Technical Specifications (provided as Attachment C.1 to this document).
4) A description of EFRI’s plan for using radiation measurement instruments for soil
background analyses, radium gamma correlations, verification data and sensitivity
analyses has been incorporated into revised sections in the Reclamation Plan which
discuss the implementation of MARSSIM guidance. Please refer to Section 6.3.2 of the
revised Technical Specifications (provided as Attachment C.1 to this document).
5) The Technical Specifications in Attachment A of the Reclamation Plan have been
revised to incorporate how MARSSIM guidance will be implemented during reclamation.
The revised Technical Specifications are provided as Attachment C.1. Specific
subsections of the Technical Specifications, Section 6 have been modified as follows:
 Calibration procedures
o See Section 6.5.1 of the revised Technical Specifications.
 Instrument testing

(MDC) for the 2-inch x 2-inch sodium iodide (NaI) scintillometer, which is approximately
104 Bq/Kg (2.8 pCi/gram) for Ra-226, according to MARSSIM Table 6.7. This MDC
depends on the background, which may raise or lower the MDC. Remediation will be
primarily driven by Ra-226, which is the contaminant with the most restrictive cleanup
standard as determined in the SENES Consultants, Inc. letter to EFRI dated August 15,
2012. This letter was provided as Attachment I to EFRI’s Supporting Documentation for

SECTION AND TEST PAD MONITORING PROGRAMS

The Division has a concern that comparing the performance of the proposed ET cover at the White Mesa
Mill Site to the performance of the Monticello tailings repository cover system is inappropriate, for
several reasons. For example, the cover system at Monticello is a composite system (having several types
of highly-specialized layers designed to accomplish various physical objectives). More specifically, the
cover system at Monticello differs significantly in design and operation from the currently selected
monolithic cover system proposed for White Mesa in that (1) the Monticello cover system includes an
animal intrusion barrier (consisting of cobbles at about 1 m (~ 3 feet) of depth), and (2) a capillary
barrier (at ~ 1.6 to 2 m, located below the animal intrusion barrier, below another layer of soil, and just
above the radon barrier). Each of these cover system components provide important functions not
accomplished in the currently-proposed monolithic soil ET cover design for White Mesa.
In addition to differences in design between the Monticello repository cover and the proposed ET cover
for the White Mesa Site, there are fundamental differences in the properties of the soils used to construct
the Monticello cover compared to the soils currently proposed for use in constructing the ET cover at
White Mesa. For instance, soils proposed by EFR for use in constructing the ET cover are extremely low
in natural organic matter (OM) content, e.g., compared to soils that were used for constructing the
Monticello Tailings Repository cover system e.g., zero to about 0.4 % according to Table D-5 in
Appendix D of the Revised ICTM Report, compared to a recommended minimum OM content of from
approximately 1.5 to 3.0%). These factors indicate that, given the natural climate conditions at the site
(which could include possible prolonged (e.g., decadal to multi-decadal) future drought periods likely to
create conditions unfavorable for sustaining plant growth in the cover), and without substantial and
extensive OM enhancements incorporated into the soils prior to cover construction and possible periodic
active post-closure intervention/maintenance measures such as reseeding, possible irrigation of the
cover, etc…, the on-site soils tested to date appear to be unfavorable for use in constructing the ET cover
(see also discussion in Section 2.3.1 of the Technical Memorandum, White Mesa Mill Site – Revised
ICTM Report Review addressing EFR’s Response to Rd 1 Interrogatory 02/1 on the Revised Infiltration
and Contaminant Transport Modeling Report).
The Division also notes the following statements made by EFR in in the Revised ICTM Report (Denison
Mines 2010):
 On Page 4-2 in the Revised ICTM Report (Denison 2010), EFR states "Furthermore, results from
nearby uranium mill tailings lysimeter at Monticello (Waugh et al., 2008) also agree with model
predictions for the proposed cover system at White Mesa." The Revised ICTM Report proceeds to
compare modeled infiltration rates at the proposed cover at White Mesa with measured
infiltration rates associated with the Monticello cover.
 On Page 4-2 in the Revised ICTM Report (Denison 2010), EFR also states “ The model-predicted
infiltration rates for monolithic ET cover are consistent with data reported from lysimeter and
infiltration modeling studies of other vegetated ET covers (e.g., Albright et al. 2004; Bolen et al.
2001; Fayer and Gee 2006; Gee et al., 1994; Scanlon et al. 2005).
After referring to studies by Bolen et al. (2001), Albright et al. (2004), and others mentioned, the Revised
ICTM Report states, "In summary, a monolithic ET cover is the preferred design to minimize infiltration
necessary to meet the Permit (Part I.D.8) and meet the radon attenuation standard." However, the cover
systems described in several of these cited references contain different design components, such as a
capillary break, that are not included in the currently proposed ET cover. For example, Bolen et al. 2001
August 31, 2015
Division’s Assessment of EFR Responses to Rd 1 Interrogatory White Mesa Rec Plan 5.0;
R313-24-4; 10CFR40, Appendix A; INT 14/1; Cover Test Section and Test Pad Monitoring Programs Page 47 of 60
review ET cover systems at 12 sites. Unlike the proposed White Mesa cover system, a number of the 12
cover systems reviewed by Bolen et al. (2001) are reported to contain either a sand layer or a gravel
layer of appreciable thickness, which may act as a capillary barrier/ capillary break. Albright et al. 2004,
who discuss the same 12 sites, state that six of them have a capillary barrier/break layer. Also unlike the
proposed cover system at White Mesa, however, nearly all (i.e., 10 of 12) of these sites have geosynthetic
root barriers consisting of nonwoven geotextile containing lumps of slow-release trifluralin (herbicide-
like plant root inhibitor) (see also Albright et al., 2004). Each barrier is installed between interim cover
and the overlying final cover system. Trifluralin acts to prevent plant biointrusion into waste by
interfering with root mitosis so that its use at a site can modify impacts of rooting, biointrusion and
drainage through a cover system.
The other studies mentioned by EFR also refer to sites with cover systems having substantial differences
from the proposed White Mesa site cover system. Fayer and Gee (2006), for example, describe
performance of four types ET cover systems at the Hanford Lysimeter Test Facility at a semi-arid site in
Hanford, Washington for periods of up to 17 years. Of interest here is that each type of cover system
described incorporates a capillary barrier/break layer, as part of the “Hanford Barrier”, in some form.
The cover design for the Crescent Junction, Utah tailings repository (relocation repository facility for the
Moab tailings) also contains a combination “Infiltration and Biointrusion” Barrier” underlying the frost
protection component of the cover and overlying the radon barrier layer in the cover (see, e.g., DOE
2012, Addendum E, p. 14).
Several published studies demonstrate that incorporating a capillary barrier (with an adjacent granular
filter layer) can substantially reduce cover infiltration rates. For example, a comparison of two otherwise
similar cover systems (one monolithic with a thick soil cover, and one non-monolithic, with a capillary
barrier) in terms of their ability to restrict drainage shows that the cover system with a thick soil cover
was outperformed by the cover system having a capillary barrier by up to a ten-to-one ratio or greater
(Porro 2001). Similar results were obtained in forced irrigation testing of alternative cover systems by
Martian et al. 2001. Infiltration reduction depends on cover-system materials and environmental
conditions. Hydraulic performance is evaluated as the probability that ET from the water-storage soil
layer overlying the capillary break layer is sufficient to prevent water accumulation in the soil sponge
layer from exceeding its storage capacity in any given year. The potential benefits in cover system
infiltration performance with a capillary barrier are well documented.
For reasons described above, the Division also finds that the technical adequacy of a monolithic ET
cover at the White Mesa site is not adequately supported by the comparisons EFR provides to other cover
systems as described in technical references cited by EFR.
With respect to a Test Pad/Test Section, the Division believes that there is value in, and a need for,
constructing and monitoring a pilot test pad or pilot test section prior to full-scale cover construction,
and in a location off of the tailings. Information and benefits that can be gained from such pilot testing
include:
 Helps establish/verify a performance standard for the cover;
 Validates the cover design and construction;
 Could result in suggestions for improved design features and construction methods when
implementing the full-scale cover construction; and
 Helps to identify and resolve problems that may be encountered during full-scale cover
construction, e.g., allow engineers to evaluate, plan for, and/or mitigate factors such as
vegetation establishment (in)effectiveness and address issues such as loss of one or more planted
species following seeding/vegetation placement, desiccation cracking during or following cover
layer placement and compaction; etc…, and

R313-24-4; 10CFR40, Appendix A; INT 14/1; Cover Test Section and Test Pad Monitoring Programs Page 48 of 60
 Provides monitoring data (e.g., from field-scale pan lysimeters) to help evaluate the future
infiltration performance of a full-scale cover constructed to a similar set of standards and using
the same construction equipment and construction methods, as well as reduces risks associated
with potential failure of, or disruption of in-situ cover conditions resulting from emplacement of,
one or more monitoring devices installed within the full-scale cover system.
Advance construction and testing of such a Test Pad or Cover Test Section would allow engineers to
obtain data on key characteristics of the constructed cover soils that are important for vegetation
establishment such as soil nutrients, propagules, and microorganisms (e.g., mycorrhizae) needed to
establish a sustainable plant community. Data collected on concentrations of soil macronutrients (e.g.,
nitrogen, phosphorus, and potassium) and micronutrients (e.g., sulfate, zinc, iron, manganese, copper,
calcium, magnesium, sodium, and boron) in the constructed test cover could be used to assess whether
they are similar to and within typical ranges for soils around the site which have been selected for use as
a natural analog or analogs for predicting the final cover vegetation characteristics and performance.
The sustainability of the ET cover may rely, in part, on the establishment and resilience of a diverse plant
community; however, the dynamics of such a plant community are complicated and effects are difficult to
predict (e.g., Waugh et al. 2008). Link et al. 1994 indicate that, even in the absence of large-scale
disturbances, seasonal and yearly variability in precipitation and temperature will cause changes in
species abundance, diversity, biomass production, and soil water extraction rates on covers. Poor shrub
establishment, for example, could result in poor water extraction, causing water accumulation in the
lower portions of the cover profile during exceptionally wet precipitation periods (percolation exceeding
the total storage capacity or drained upper limit of the soils). Data on soil structure development
observed to occur over time within a constructed test cover profile following its construction could also
be acquired and compared to that observed in natural soils at the selected analog site(s) to assess
conditions that could be expected to develop in the future full-scale cover with respect to whether they
may be suitable for promoting future development and sustainability of such shrubs, if desired based on
the cover infiltration modeling results.
On the basis of the considerations discussed above, the Division requests the following:
 EFR will need to provide a detailed Technical Work Plan for Division review and approval, no
later than 90 days after approval of the revised Infiltration and Contaminant Transport Modeling
(ICTM) Report by the Division, for constructing, monitoring and testing a Cover Test Pad//Test
Section representative of the intended full-scale cover system. The Work Plan shall: (1) provide a
construction schedule; (2) provide details of the proposed Test Pad/Section’s design and
construction; (3) describe the proposed monitoring/testing program duration; (4) define
parameters to be monitored/tested in the Test Pad/Test Section; (5) provide a schedule and
details regarding reporting of monitoring and testing results; (6) describe objectives of the Test
Pad/Test Section construction, monitoring, and testing program; and (7) propose and justify
criteria for demonstrating that those objectives have been achieved.
 The Test Pad/Test Section Work Plan will need to address acquisition of data for parameters
(e.g., percolation data, weather data, fertilization and nutrient content data and other soil testing,
botanical data,...) to validate assumptions and predictions made by EFR with regard to the
projected site-specific and cover-specific performance of the full-scale cover, including future
emergence rates and characteristics of vegetation on the cover.
 The Reclamation Plan should be revised to incorporate the information and requirements
described herein with regard to this Test Pad/Test Section.
EFR’s proposal to maintain a rough surface on all but the uppermost lift in the cover is acceptable and
EFR should incorporate this commitment into Attachment A of the next revision of the Reclamation Plan.

Response:

The response to the suitability of the White Mesa cover soils relative to vegetative
growth and sustainability is addressed in the response to Interrogatory 11/1.

EFRI has added the requirements to maintain a rough surface on all but the uppermost
lift of the cover system in the Technical Specifications. The revised Technical
Specifications are provided in Attachment C.1.

A workshop was conducted on April 30, 2013 with representatives from the Division, the
Division’s contractor (URS), EFRI, MWH, and Dr. Craig Benson to discuss Division’s
February 2013 review comments on the Reclamation Plan, Revision 5.0 (DRC, 2013b)
and the revised ICTM Report (DRC, 2013a). During this workshop, Dr. Benson
presented a comparison of the White Mesa cover design to the Monticello cover design,
as well as information on construction of of cover test pads and test monitoring sections.
Discussion from this workshop on these topics is summarized in the paragraphs below
for this response and was prepared by Dr. Benson. Dr. Benson is the lead author for
NUREG/CR-7028 (Benson et al., 2011) and was a lead inspector for the US EPA’s
Alternative Cover Assessment Program (ACAP), as described in Benson et al. (1999,
2001) and Malusis and Benson (2006). EFRI has engaged Dr. Benson in the cover
design for the White Mesa tailings cells with regards to selection of and evaluation of
laboratory testing of the cover materials, comparison of the EFRI cover design with the
Monticello cover system, development of a plan for the cover test section, and with
evaluation of the long-term properties for the cover soils.

EFRI acknowledges that soil layering in the cover profile at the Monticello Uranium Mill
Tailings Disposal Facility differs from layering in the monolithic cover proposed for the
White Mesa facility. The Monticello cover includes an animal intrusion layer as well as a
sand layer at the base, the latter intended to create a capillary break (Figure 1). The
cover at Monticello also includes a geomembrane overlying a clay radon barrier at the
base. However, the hydrological monitoring conducted at Monticello pertains only to that
portion of the cover above the geomembrane, i.e., that portion of the cover functioning
as a water balance cover (aka an evapotranspirative cover).

Although the Monticello cover has different elements than the monolithic cover proposed
for White Mesa, the cover at Monticello functions as a monolithic cover, as illustrated by
the water content record shown in Figure 2.

In all but the wettest years, nearly all of the infiltrating water is managed in the upper
900-mm-thick storage layer, making the impact of the underlying layers unimportant.
During those years the cover functions like at 1100-mm thick monolithic cover (surface
layer + upper storage layer) (Figure 2). In very wet years, variations in water content
occur more deeply, including in the intrusion layer, the underlying 300-mm-thick storage
layer, and the sand layer at the base. The variations in water content follow the same
pattern as water contents in the upper storage layer, exhibiting the continuity and
smooth variation in water content with time and depth that occurs in a monolithic cover.

For example, water contents in each layer are shown in Figure 3 for winter 2004 - 2005,
the wettest and snowiest on record. The water content in each layer varies steadily and
continuously over months rather than exhibiting an abrupt and sudden change that
August 31, 2015
Division’s Assessment of EFR Responses to Rd 1 Interrogatory White Mesa Rec Plan 5.0;
R313-24-4; 10CFR40, Appendix A; INT 14/1; Cover Test Section and Test Pad Monitoring Programs Page 50 of 60
would occur if a capillary break existed at the intrusion layer or at the sand layer. In fact,
the water content of the sand layer increases appreciably before the overlying lower
storage layer approaches saturation, indicating that a capillary break effect is not
occurring at the interface between the lower storage layer and the sand layer.

Another example is shown in Figure 4, which depicts the water content in each layer
from mid-winter to late summer 2010, which included an exceptionally wet spring during
which water penetrated the entire cover profile (Figure 2). The water content records in
Figure 4 show a steady downward movement of the wetting front in the profile. There is
no “hold up” of the wetting front at the intrusion layer or the sand layer. Moreover, water
migrates into the animal intrusion layer and the sand layer without the overlying layers
(upper storage layer and lower storage layer, respectively) approaching saturation,
indicating that a capillary break was not forming at either interface.

There are reasons why the Monticello cover functions like a monolithic cover, even
though the layering may suggest that different behavior should occur in response to
contrasts in soil texture. First, the intrusion layer consists of cobble particles embedded
in a fine-textured soil matrix. This matrix is comprised of the same fine-textured soil
used for the upper and lower storage layers, and provides capillary connectivity between
the upper and lower storage layers. Cobble in the intrusion layer does reduce the pore
space available for soil water storage, but does not alter the hydrologic dynamics or
inhibit the flow of water up or down in the profile. The reason for the absence of a
capillary break at the interface between the lower storage layer and the sand is not
clear, but the deep location of this interface is a likely cause. The interface may also
have been invaded by fines from the overlying lower storage layer during construction,
which would provide a capillary conduit between the lower storage layer and the sand
layer. Regardless of the mechanism, however, the water content data do indicate that
the interface between the lower storage layer and the sand does not create a capillary
break.

Thus, while the layering in the cover at Monticello may differ from that at White Mesa,
both covers function as monolithic covers, and both are in similar climates (Monticello
being slightly wetter and snowier than White Mesa) and are comprised of similar
materials. For these reasons, Monticello is an appropriate analog for White Mesa, and
probably is the most suitable analog available. Over the past 15 years (2000-2015), the
annual percolation rate for Monticello has ranged from 0.0 to 3.8 mm/yr, and has
averaged 0.5 mm/yr. During this period, annual precipitation has ranged from 232 to 535
mm and averaged 351 mm, including the wettest and snowiest winter on record (2004-
2005). Given these similarities, the cover proposed for White Mesa should provide
similar or better hydrologic isolation.

EFRI understands the Division’s position regarding construction of a test section
adjacent to the disposal facility that might lead to lessons learned that could be used to
improve on, or optimize the cover design. EFRI will be placing the majority of the final
cover on Cell 2 after approval of the Reclamation Plan and License Renewal, and will
construct a test section within the actual cover (for the full cover profile). This test
section, which will be constructed over actual tailings using the same full-scale methods
employed for the actual cover, will provide a more realistic representation of cover
performance than a test section adjacent to the facility. Moreover, because only a
portion of the cover will have been constructed at this point, less learned from the test
section can be applied to other areas of the facility as additional final cover is
constructed.

EFRI is proposing that the test section be designed, constructed, and monitored using
principles developed during US EPA’s Alternative Cover Assessment Program (ACAP),
as described in Benson et al. (1999, 2001) and Malusis and Benson (2006). The ACAP
methodology has been employed to evaluate nearly 50 final cover designs, and has
been adopted as the de facto standard for final cover monitoring in the US and abroad.
The ACAP methodology is currently being used to monitor the final cover at DOE’s
Monticello Uranium Mill Tailings Disposal Facility and to evaluate the performance of the
cover design employed at DOE’s Grand Junction Disposal Facility near Cheney,
Colorado. The US Nuclear Regulatory Commission also recommends the ACAP
methodology for monitoring the performance of final covers in NUREG/CR-7028
(Benson et al. 2011).

EFRI will engage ACAP investigators (i.e. Dr. Craig Benson) when developing,
constructing, and monitoring the test section, and defining the program details
mentioned in the interrogatory. The monitoring system will include instruments to
measure all components of the water balance, including percolation from the base of the
cover, and on-site meteorological conditions. A complementary surveillance program will
also be developed to monitor the vegetative community, edaphic properties of the cover
soils, and pedogenic evolution of the cover profile, as suggested in NUREG/CR-7028.
Comparisons will be made between the monitoring data and predictions and
assumptions made when developing the proposed cover design.

FINANCIAL SURETY ARRANGEMENTS

EFR must submit and receive approval of its revised cost estimates before the Division will approve
EFR’s proposed and revised cover system design.
EFR has inadequately addressed the time required to dewater Cell 2 and Cell 3 prior to final cover
construction, EFR should submit technically supported quantitative projections of the times required to
achieve moisture contents for these cells upon which the final covers can be constructed with expectation
that the dewatered tailings will not likely contribute to instabilities in the covers. These quantitative
analyses should consider all mechanisms that affect water content of the tailings, including (but not
limited to) precipitation, runoff, infiltration, lateral drainage, transpiration, evaporation, percolation,
groundwater migration, and active removal. Quantitative analyses should also include uncertainty and
sensitivity analyses to account for known and likely uncertainties in input parameter values and their
effects on dewatering. The Reclamation Plan must include a detailed description of dewatering measures
that EFR will use to accomplish dewatering of Cells 2 and 3 within the 7 year-time period specified in the
latest Financial Surety submitted to the Division by EFR (See also Section 7.3 above). The current
Surety submittal of March 14, 2012 (including the revised submittal dated September 14, 2012) does not
list the time to dewater Cell 2. However, all other cells show a 62,400 hour dewatering time). Costs of
the specific dewatering measures need to be included in the Financial Surety. Because this revised
evaluation and the revised reclamation cost estimates described above were not submitted with EFR’s
response to the Rd 1 interrogatories, this issue will remain open.

Response:

EFRI conducted a tailings investigation of Cells 2 and 3 in October 2013 at the White
Mesa Mill site to address the Division’s comment for Interrogatories 07/1 and 09/1
requesting collection of site-specific tailings data to supplement existing tailings data
used for settlement analyses. The results are presented in MWH (2015). Results of the
investigation indicated migration of water towards the sump in Cell 2. This is expected
since water has been pumped from the Cell 2 sump since 2008. Quantatative
projections of time to achieve acceptable tailings moisture contents for cover placement
cannot be made without additional information on the rate of drainage from the tailings
due to Cell 2 dewatering. To further evaluate the change in water levels due to
dewatering in Cell 2 prior to and after final cover placement, EFRI plans to install mini-
piezometers across the cells prior to the first phase of cover placement. This data will
provide information on the rate and extent of dewatering of the cells to confirm when the
final phase of cover can be placed and when active maintenance is no longer required.

Costs associated with dewatering were provided in the most recent surety submitted to
the Division in 2014. These costs will also be included in the surety to be provided in the
next version of the Reclamation Plan.

The Division requests that EFR revise the RPM to specify how the program will be modified to address
the unique decommissioning requirements, or the process through which the manual and program will be
revised in the future. EFR should also include procedures for gamma radiation surveys in the revised
RPM that are discussed in the response document. Because this revised information was not submitted
with the response, this interrogatory will remain open.

Response:

The Radiation Protection Manual (RPM) will be modified during the decommissioning
process as needed. During the decommissioning process if it is determined that the
current RPM does not take into account specific items, then the SERP process will be
utilized to amend the RPM in order to address those situations. The SERP summary
report will continue to be submitted to the State of Utah, Division of Waste Management
and Radiation Control (DWMRC) on an annual basis and will be available upon request
at the White Mesa Mill.
Section 2.7 of the RPM now states that the gamma survey for the decommissioning of
the site will be conducted in accordance with the most current approved Reclamation
Plan, Section 6 of the Technical Specifications. The updated RPM is provided as
Attachment I.

EFR should yet either (1) cite previously submitted documents where these topics were addressed or (2)
develop and submit for the Division’s review and approval the following:
 Decontamination procedures for buildings and equipment.
 Disposal of building components and equipment either on-site or off-site, depending on results of
release surveys.

Response:

The Reclamation Plan states that buildings and equipment will be disposed of on-site. If
it is determined that some materials are not contaminated and may be free released
from the site, then the existing procedure and free release criteria will be used as stated
in the RPM Section 2.6 and in accordance with the NRC guidance for “Decontamination
of Facilities and Equipment Prior to Release for Unrestricted Use” (dated April 1993)
Additional guidance documents referenced in the Technical Specifications, Section 6,
will be used as appropriate and applicable to the items being released for unrestricted
use.
Decontamination procedures for items to be released for unrestricted use will be
developed during reclamation and will be based on the type of equipment and the
construction of the equipment (i.e. what the item is constructed of such as metal, glass,
plastic etc.). Current Mill procedures will be the basis for the decontamination
procedures used at the time of reclamation. If decontamination to the unrestricted
release criteria specified in the RPM Section 2.6 is not attainable, the item will be
disposed of on site.

EFR has inadequately defined the responsibilities and duties of the Radiation Safety Officer in its
revision of the Radiation Protection Manual for Reclamation.
EFR has committed to, but must yet revise Section 1.8b of the Technical Specifications to indicate that
the Division must review and approve all reclamation plan design modifications.

Response:

Section 1 of the RPM, which delineates the RSO responsibilities and duties, has been
modified to include the following “The RSO will have the responsibility of overseeing all
aspects of this procedure and all total releases of any materials from the facility.” The
updated RPM is provided as Attachment I.
Section 1.8b of the Technical Specifications has been revised to indicate that the
Division must review and approve all design modifications to the Reclamation Plan. The
revised Technical Specifications are provided in Attachment C.

must yet actually revise the document and submit it for the Division’s review and approval.

Response:

The Technical Specifications in Attachment A of the Reclamation Plan have been
revised to incorporate and reference NUREG-1575 (NRC, 2000), NUREG-1575
Supplement 1 (NRC, 2009) and NUREG-1757 (NRC, 2006) guidance. The revised
Technical Specifications are provided as Attachment C.1.

EFR reasonably addresses the nine topics contained in Items 1 through 9 of the interrogatory. The
response provides procedures for how gamma surveys may be conducted and indicate instruments that
may be used. These procedures and instruments are not included in the RPM. Additionally, a discrepancy
exists between the RPM and the response document regarding the frequency of instrument calibrations.
Section 3.1.4.2 of the RPM state “All beta-gamma survey instruments are sent out annually for
calibration” whereas the response states “As indicated in the Mill’s Radiation Protection Reclamation
Manual each existing instrument (Ludlum 19) used will be calibrated by an offsite –third party every 6
months.
The Division requests that EFR incorporate the substance of these responses into the further revised
Technical Specifications or other documentation pertinent to the Reclamation Plan. EFR must also
resolve the discrepancy stated above. Because this revised information was not submitted with the
response, this interrogatory will remain open.

Response:

Section 2.7 of the RPM now states that the gamma survey for the decommissioning of
the site will be conducted in accordance with the most current approved Reclamation
Plan, Section 6 of the Technical Specifications.
The calibration frequency for beta-gamma survey instruments is every 6 months. The
RPM has been corrected. The updated RPM is provided as Attachment I.

3.0 INSPECTION PROCEDURES
3.1 Asbestos-Containing Material (ACM)
IHI visually inspected all accessible areas of the building to identify suspect ACM. To assess
the condition and determine friability of the suspect materials, IHI visually examined and
touched all accessible surfaces, structures, and mechanical systems within the building.
Suspect ACM was identified and assessed by homogeneous areas. A homogeneous area is
defined as a single material, uniform in texture and appearance, installed at one time, and
unlikely to consist of more than one type, or formulation, of material. In cases where joint
compound and/or tape has been applied to wallboard (gypsum board) and cannot be visually
distinguished from the wallboard, it is considered an integral part of the wallboard and in
effect becomes one material forming a wall or ceiling "system."
Mill-Boiler-Scale House-White Mesa Mill
Denison Mines Asbestos Inspection
2 IHI Environmental
Project No. 12U-Al 081
Each homogeneous area was given a unique material identification (ID) number. Each ID
number begins with a letter: "S" for surfacing materials, "T" for thermal system insulation, or
"M" for miscellaneous materials. This letter is followed by a three-digit number, assigned in
consecutive order. This number is used to identify that specific homogeneous area
throughout the inspection report.
3.2 Bulk Sampling
To determine the asbestos content of materials, IHI collected bulk samples from all
accessible homogeneous areas of suspect ACM and submitted the samples to an accredited
laboratory for analysis.
The number of samples collected from each homogeneous area generally followed the U.S.
Environmental Protection Agency (EPA) Asbestos Hazard Emergency Response Act
(AHERA) regulations ( 40 CFR §763.86). Friable surfacing materials were sampled using the
random sampling scheme given in the EPA publication 560/5-85-030a, titled "Asbestos in
Buildings: Simplified Sampling Scheme for Friable Surfacing Materials." Bulk sample IDs
collected during the inspection were entered on chain-of-custody forms for submittal to the
analytical laboratory.
3.3 Bulk Sample Analysis
Bulk samples were analyzed using polarized light microscopy (PLM) and visual estimation
according to the EPA Interim Method for the Determination of Asbestos in Bulk Insulation
Samples, EPA-600/M4-82-020. Samples were analyzed by Dixon Information Inc. in Salt
Lake City, Utah. Dixon Information is accredited under the National Institute of Standards
and Technology, National Voluntary Laboratory Accreditation Program (NIST-NVLAP) for
bulk asbestos sample analysis, and is also accredited by the American Industrial Hygiene
Association (AIHA).
EPA's National Emissions Standards for Hazardous Air Pollutants (NESHAP) and AHERA
regulations define ACM as material containing greater than I% asbestos by weight; materials
containing 1 % or less asbestos are not considered regulated ACM by the EPA. Further, the
NESHAP regulations state that any sample found to contain less than 10% asbestos but
greater than "none detected," by the visual estimation method used during PLM analysis,
Mill-Boiler-Scale House-White Mesa Mill
Denison Mines Asbestos Inspection
3 IHI Environmental
Project No. 12U-A108 l
must be assumed to contain greater than I% asbestos unless confirmed by NESHAP point
counting analysis.1
Despite EPA (and Utah Division of Air Quality) rules exempting building materials
containing I% or less asbestos from stringent regulation, Occupational Safety and Health
Administration (OSHA) regulations outline specific precautionary work practices when
employees work with materials containing even trace amounts of asbestos.2
The laboratory reports can be found in Appendix D of this report.
4.0 INSPECTION RESULTS
4.1 Asbestos-Containing Materials
The Executive Summary and Table 1 in Appendix A list all homogeneous areas that contain
asbestos. Each material is described by type of material, friability and visual appearance.
Friability is defined in accordance with EPA's NESHAP regulations.
• "Friable ACM" is any material containing more than I% asbestos (as determined by
PLM) that, when dry, may be crumbled, pulverized, or reduced to powder by hand
pressure and also includes non-friable ACM that may become friable during building
demolition.
• "Non-friable ACM" is any material containing more than I% asbestos (as determined
by PLM) that, when dry, cannot be crumbled, pulverized, or reduced to powder by
hand pressure.
• "Category I non-friable ACM" are asbestos-containing resilient floor coverings
(commonly known as vinyl asbestos tile (VAT)), asphalt roofing products, packings,
and gaskets.
• "Category II non-friable ACM" encompasses all other non-friable ACM.
1 NESHAP point counting includes examining materials under a polarizing microscope using an eyepiece
reticule that superimposes a grid of points over the field of view. 400 points are examined.
2 OSHA regulations pertaining to asbestos in buildings include 29 CFR 1926.1101 and 29 CFR 1910.1001.
OSHA has also issued interpretive letters that provide clarification about how materials containing less than 1 %
asbestos should be handled. (see www.osha.gov)

Project No. 12U-Al08 l
• "Non-friable RACM" is used to denote thermal system insulation that is in good
condition but would become friable during renovation or demolition and therefore is
"regulated asbestos containing material" (RACM).
4.2 Non-Asbestos-Containing Materials
Homogeneous areas of suspect ACM are identified as non-ACM if material contains no
detectable asbestos. Table 2, located in Appendix A of this report, lists all homogeneous
areas that were found to be non-ACM.
4.3 Bulk Sample Analytical Results
Table 3, located in Appendix A of this report, lists all the bulk samples (chronologically by
sample number) collected from homogeneous areas of suspect ACM, and the laboratory
analytical results. Each sample was given a unique sample number. There may be more than
one sample number for the same homogeneous area of suspect ACM indicating multiple
samples were collected from that homogeneous material. The homogeneous areas of suspect
ACM are identified on this table by their material identification numbers. The sample
location listed on this table provides a brief, but specific, description of the location where
the sample was collected. This is different from the homogeneous area location provided on
Tables 1 and 2. Table 4 is the same as Table 3, except that the entries have been sorted by
homogeneous area number.
4.4 Damage and Hazard Assessment
Each homogeneous area of ACM was assessed for existing damage, accessibility, and
potential for future damage, this information is presented in Table 5, located in Appendix A
of this report. This table also lists the substrate beneath each homogeneous area of ACM.
Damage and hazard assessment categories are included in the tables in Appendix A.
4.5 Materials Requiring Special Considerations
The inside of the metal boiler and metal boiler flue could not be accessed during the
inspection.

Project No. 12U-Al081
4.6 Assumed Asbestos-Containing Materials
None
4.7 Inaccessible Areas
Suspect materials that were hidden or inaccessible may not have been characterized by this
inspection. Therefore, any material not identified in this report as having been tested should
be treated as suspect ACM until it has been sampled by a Utah-certified inspector and
analyzed by an accredited laboratory applying EPA methods.
In addition, some building structures may have been constructed after the application of
ACM, and therefore may have obscured these materials from visual examination during this
inspection. Typical scenarios include thermal system insulation inside hardened mechanical
chases, floor tile and mastic under walls, and sprayed-on texturing and fireproofing behind
structural supports or architectural features.
4.8 Materials Assumed >1 % Asbestos (no NESHAP point count)
None
5.0 RESPONSE ACTIONS
5.1 Applicable Rules and Regulations
In Utah, EPA asbestos regulations are administered by the Utah Division of Air Quality
(DAQ).3 The Utah Occupational Safety and Health Administration (UOSH) has adopted the
Federal OSHA regulations.4 In addition, the Salt Lake Valley Health Department (SLVHD)
regulates demolition activities in Salt Lake County. 5 The SLVHD regulations for pre-
demolition building inspections require an asbestos inspection, but also require building
owners to inspect the building for other hazardous materials such as universal wastes,
hazardous and toxic wastes, and lead-based paint. Like asbestos, these wastes, if present,
must be removed prior to building demolition.

Regulatory factors relevant to asbestos abatement decision-making are included in Appendix E.
5.2 Renovation and Demolition (EPA and OSHA)
A listing of ACM found during this inspection is presented in the Executive Summary at the
front of this report, and in Appendix A, Table I.
NESHAP regulations require the removal of friable ACM and non-friable ACM that could
become friable during demolition or renovation activities. Therefore, we recommend that all
of the ACM in this building be removed and properly disposed of by a licensed asbestos
abatement contractor if total demolition of the facility is planned, or those materials that will
be impacted by renovation plans be removed prior to the commencement of renovation work.
Despite EPA (and Utah Division of Air Quality) rules exempting building materials
containing I% or less asbestos from stringent regulation, Occupational Safety and Health
Administration (OSHA) regulations outline specific precautionary work practices when
employees work with materials containing even trace amounts of asbestos.6 Strict
compliance by building owners with the OSHA asbestos regulations may result in response
actions not required by the EPA and Utah DAQ for certain unregulated materials.
6.0 COST ESTIMATES
Details of the estimated removal costs by homogeneous area can be found in Table 6,
Appendix A, and in the Executive Summary table. These estimates are provided for
budgeting and planning only, and do not have a level of accuracy sufficient to be used as a
construction design cost estimate. The actual cost of asbestos removal is dependent on
factors such as the size of the job, the required time frame for removal, the time of year the
job is conducted, and economic factors. These estimates do not include replacement costs, or
the cost for asbestos abatement design and management consulting services.
6 OSHA regulations pertaining to asbestos in buildings include 29 CFR 1926.1101and29 CFR 1910.1001.
OSHA has also issued interpretive letters that provide clarification about how materials containing less than 1 %
asbestos should be handled. (see www.osha.gov)

Appendix "A"
''This repo1t relates only to the items tested. This report must not be used to claim
product endorsement by NVLAP or AIHA."
NVLAP and AIHA requires laboratories to state the condition of samples received for
testing: These samples are in acceptable condition for analysis unless there is a statement
in the report of analysis that a test item has some characteristics or condition that
precludes analysis or requires a modification of standard analytical methodology. If a test
item is not acceptable) the reasons for non-acceptability will be given under the
laboratory number for that particular test item. The reported percentages of each material
type are based on the sample received by the laboratory and may not be representative of
the parent material. Orientation of top and bottom may not be specified due to uncertainty
of orientation.
Methods of Analysis and Limit of Detection
In air count analysis, the results may be biased when interferences are noted.
The accuracy of asbestos analysis in bulk samples increases with increasing
concentration of asbestos. Pigments, binders, small sample size, and multiple layers may
affect the analysis sensitivity.
There are two methods for analysis of asbestos in a bulk test sample. Visual
estimation is the most sensitive method. If an analyst makes a patient search, 0.1 % or less
asbestos can be detected in a bulk sample.
The second method of analysis is a statistical approach called point counting. EPA
will not accept visual estimations if a laboratory detects a trace of asbestos in a sample
i.e. anything less than l % asbestos. Government agencies regulate asbestos containing
materials (ACM) whenever the ACM is more than 1 %. OSHA requirements apply on
samples containing any amount of asbestos.
Due to the higher charge for a point count analysis, Dixon Information Inc. does not
perform a point count unless authorized to do so by the client. If a sample is point
counted, when possible, various chemical and/or physical means may be used to
concentrate the asbestos in the sample. This is permitted by the EPA method and it
increases the accuracy of the analysis.
AppendixE
Regulatory Factors
Several factors determine how asbestos in a building must be treated if it has the potential of
being disturbed during a renovation or demolition. These factors include the following:
EPA Regulations for OSHA Regulations for
Factor Asbestos Removal Asbestos Removal
Definition of asbestos Defines ACM as a material Defines an ACM as one containing
in a building material containing 1 % or greater asbestos. > 1 % asbestos.
Regulation of asbestos Regulates only ACM. If the asbestos Regulates not only ACM but all
in building materials concentration in a material is shown materials containing any amount of
to be "none detected" by initial asbestos. Regulations are not as
analysis or 1 % or less by point count stringent for materials containing
analysis, EP A/DAQ does not regulate equal-to or less-than 1 % asbestos but
it. greater than a "none detected"
concentration.
Determination of Allows compositing of all layers Requires that each layer of the wall

in a gypsum board gypsum board) into one sample, independently, which increases the
wall system which decreases the possibility that possibility of a sample containing

Project Limitations
PROJECT LIMITATIONS
This Project was performed using, as a minimum, practices consistent with standards
acceptable within the industry at this time, and a level of diligence typically exercised by
EH&S consultants performing similar services.
The procedures used attempt to establish a balance between the competing goals of limiting
investigative and reporting costs and time, and reducing the uncertainty about unknown
conditions. Therefore, because the findings of this report were derived from the scope, costs,
time and other limitations, the conclusions should not be construed as a guarantee that all
universal, toxic and/or hazardous wastes have been identified and fully evaluated.
Furthermore, IHI assumes no responsibility for omissions or errors resulting from inaccurate
information, or data, provided by sources outside of IHI or from omissions or errors in public
records.
It is emphasized that the final decision on how much risk to accept always remains with the
client since IHI is not in a position to fully understand all of the client's needs. Clients with a
greater aversion to risk may want to take additional actions while others, with less aversion to
risk, may want to take no further action.

Manager, and RSO each have the authority to stop Contractor work if unsafe conditions or
deviations from Technical Specifications are observed.
1.13 Personnel Monitoring
Programs currently in place for monitoring of exposures to employees will remain in effect
throughout the time period during which tailings cell reclamation, mill decommissioning and
clean up of windblown contamination are conducted. These programs will include personnel
monitoring and the ongoing bioassay program. Access control will be maintained at the
Restricted Area boundary to ensure employees and equipment are released from the site in
accordance with the current License conditions. In general, no changes to the existing programs
are expected and reclamation activities are not expected to increase exposure potential beyond
the current levels. The Owner will assign an employee to act as RSO responsible for assuring
site workers comply with the Owner’s Radiation Protection Manual for Reclamation and the
requirements set forth in the Owner’s radioactive materials license.
1.14 Environmental Monitoring
Existing environmental monitoring programs will continue during the time period in which
reclamation and decommissioning is conducted. This includes monitoring of surface and
groundwater, airborne particulates, radon, soils and vegetation, according to the existing License
conditions. In general, no changes to the existing programs are expected and reclamation
activities are not expected to increase exposure potential beyond the current levels.

2.0 SITE CONDITIONS
2.1 Site Location
The White Mesa mill site is located about 6 miles south of Blanding, Utah in San Juan County,
along County Road 191.
2.2 Climate and Geology
The climate of southeastern Utah is classified as dry to arid continental. Although varying
somewhat with elevation and terrain, the climate in the vicinity of the mill can be considered as
semi-arid with normal annual precipitation of about 13.3 inches. The mean annual relative
humidity is about 44 percent and is normally highest in January and lowest in July. The average
annual Class A pan evaporation rate is 68 inches (National Oceanic and Atmospheric
Administration and U.S. Department of Commerce, 1977), with the largest evaporation rate
typically occurring in July. (Denison, 2009)
The mill is located within the Blanding Basin of the Colorado Plateau physiographic province.
The average elevation of the site is approximately 5,600 ft (1,707 m) above mean sea level
(amsl). Typical of large portions of the Colorado Plateau province, the rocks underlying the site
are relatively undeformed. The site is underlain by unconsolidated alluvium and indurated
sedimentary rocks consisting primarily of sandstone and shale. The alluvial materials consist
mostly of aeolian silts and fine-grained aeolian sands with a thickness varying from a few feet to
as much as 25 to 30 ft (7.6 to 9.1 m) across the site. The alluvium is underlain by the Dakota
Sandstone and Burro Canyon Formation, which are sandstones having total thicknesses ranging
from approximately 100 to 140 ft (31 to 43 m). (Denison, 2009)
2.3 Past Operations
The mill is a uranium/vanadium mill that was developed in the late 1970's by Energy Fuels
Nuclear, Inc. (“EFN”) as an outlet for the many small mines located in the Colorado Plateau and
for the possibility of milling Arizona strip ores. Construction on the tailings area began on
August 1, 1978. The mill was operated by EFN from the initial start-up date of May 6, 1980 until

3.0 WORK AREA PREPARATION
3.1 General
This Section describes the preparation of site areas for reclamation. This work will be conducted
according to applicable sections of the Owner’s Radiation Protection Manual for Reclamation.
3.2 Water Management
Preparation for work in the site area will include water management tasks outlined below.
a. Removal of raffinate crystals from Cell 1.
b. Breaching of the Cell 1 dike for construction the cell as a sedimentation basin. Re-route
runoff from the mill area and areas immediately north of the cell into the sedimentation
basin for discharge onto the natural ground via the channel to be located at the southwest
corner of the basin.
c. Diversion of clean area storm water runoff from work areas (where facilities demolition
and material excavation will take place) and from the disposal cell footprint area.
d. Collection of storm water runoff from within the work areas and the disposal cell
footprint for treatment and permitted discharge, or for disposed material compaction or
dust control. The planned storage location for this affected storm water is the
sedimentation pond.
e. Isolation of water used for processing operations associated with reclamation from storm
water runoff. Water from processing operations or other contaminated water will not be
used for disposal cell construction.
3.3 Cell Construction
A clay lined disposal area will be constructed adjacent to and parallel with the existing Cell 1
dike for permanent disposal of contaminated material and debris from the mill site

decommissioning and the Cell 1 Disposal Area. The area will be lined with a 12-inch thick layer
of compacted clay prior to placement of contaminated materials and installation of the final
reclamation cap. If there is not sufficient debris, rubble and contaminated soil to fill Cell 1 as
designed, the footprint of Cell 1 can be reduced to decrease the horizontal dimension extending
out from Cell 2 and the lateral extent of the disposed materials, to be closer to the base of the
Cell 2 dike. If a design modification is required for Cell 1, it will be submitted to DWMRC for
review and approval and these Technical Specifications will be revised accordingly.
3.4 Soil Borrow Areas
Disposal cell fill and liner materials will be excavated from among the identified borrow areas on
site. Cover and liner soil will be from suitable materials stockpiled on site during cell
construction.
Specific soil borrow areas will be selected based on haul distance to the disposal cell, ease of
excavation of cover material, geotechnical characteristics, uniformity of the borrow material, and
acceptable radiological and geochemical characteristics.
Borrow area preparation will consist of setup for storm water management (Section 3.2) and
clearing and stripping (Section 3.5).
3.5 Clearing and Stripping
For work areas that are vegetated, preparation work will include tasks outlined below.
3.5.1 Clearing
Clearing of vegetation and grubbing of roots will be in identified work areas. Clearing and
grubbing shall not extend beyond 20 feet from the edge of the work area, unless as shown on the
Drawings or as approved by the Reclamation Project Manager.
Vegetation from clearing and grubbing may be shredded or chipped to form mulch. Alternative
methods of on-site or off-site disposal or burning of stripped vegetation shall be conducted only
as approved by the Reclamation Project Manager.

4.0 CELL 1 DISPOSAL AREA BASE CONSTRUCTION
4.1 General
This section outlines work associated with construction of the disposal cell base for receipt of
materials (as described in Section 7.0) within Cell 1. The base of the disposal cell will be lined
with a compacted clay liner. The cell base will be constructed as shown on the Drawings and
outlined in these Technical Specifications.
4.2 Materials Description
4.2.1 Subgrade Fill
The disposal cell footprint is likely to have an irregular surface from areas that have been
excavated. Low areas of the excavated surface should be filled to form a smooth, competent
foundation for clay liner construction. Subgrade fill will be used in excavated areas of the
disposal cell footprint to meet desired grades and elevations for the disposal cell foundation
(shown on the Drawings).
Subgrade fill may consist of off-site granular materials, or soils and weathered sedimentary rock
from approved on-site excavation areas. Subgrade fill shall be minus 6-inch size, and shall be
free from roots, branches, rubbish, and process area debris.
4.2.2 Clay Liner Material
Clay liner material shall be minus 1-inch size, and shall be free from roots, branches, rubbish,
and process area debris. Clay liner material shall have a minimum of 40 percent passing the No.
200 sieve and a minimum plasticity index (PI) of 15 percent. Suitable materials will classify as
CL, CH, or SC materials under the Unified Soil Classification System.

August 2015
4.3 Work Description
4.3.1 Foundation Preparation
The footprint of the disposal cell shall form a competent foundation for clay liner and cover
construction. The surface of the disposal cell footprint shall be filled (where required) in low
areas to form a smooth, competent foundation for clay liner and cover construction. Subgrade
fill (Section 4.2.1) shall be placed in lifts and compacted in excavated areas of the disposal cell
footprint to meet desired grades and elevations for the disposal cell foundation (shown on the
Drawings). The final filled surface shall be compacted with approved construction equipment to
provide a foundation surface with uniform density for clay liner placement.
4.3.2 Disposal Cell Foundation Area
The footprint of the disposal cell is established along the north side of the tailings dike along the
south edge of Cell 1 (shown on the Drawings).
4.3.3 Subgrade Fill Placement
Subgrade fill (Section 4.2.1) shall be placed in lifts and compacted in excavated areas of the
disposal cell footprint to meet desired grades and elevations for the disposal cell foundation.
Subgrade fill may be (1) granular material from off-site commercial sources, or (2) soils and
weathered sedimentary rock from approved on-site excavation areas.
4.3.4 Clay Liner Material Placement
Clay liner material (Section 4.2.2) shall be placed in lifts with a maximum compacted thickness
of 6 inches to form a continuous layer with a total minimum compacted layer thickness of 12
inches. Clay liner material shall be placed over the prepared subgrade surface of the disposal
cell (Section 4.3.1).
Compaction of the clay liner material shall be done with a sheepsfoot or tamping-foot roller of
sufficient weight to achieve the required compaction specifications. Rubber-tired equipment
shall not be used solely to compact the clay liner material.
Page A-19
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
If the moisture content of any layer of clay liner is outside of the allowable placement moisture
content range specified, the material shall be moistened and/or reworked with a harrow, scarifier,
or other suitable equipment to a sufficient depth to provide relatively uniform moisture content
and a satisfactory bonding surface before the next layer of clay material is placed. If the
compacted surface of any layer of clay liner material is too wet (due to precipitation) for proper
compaction of the fill material to be placed thereon, it will be reworked with a harrow, scarifier
or other suitable equipment to dry out the layer and reduce the moisture content to within the
required limits. The layer would then be re-compacted.
The layers of the placed clay liner will be such that the liner will, as far as practicable, be free of
lenses, pockets, streaks or layers of material differing substantially in texture, gradation or
moisture content from the surrounding material. Oversized material will be controlled through
selective excavation of stockpiled material, observation of placement by a qualified individual
with authority to stop work and reject material being placed and by culling oversized material
from the fill.
No clay liner material will be placed when either the materials, or the underlying material, is
frozen or when ambient temperatures do not permit the placement or compaction of the materials
to the specified density without developing frost lenses in the fill.
Any holes in the clay liner material resulting from testing should be repaired by hand by filling
with clay fill, or by filling with bentonite powder which is hydrated to fully seal the hole.
4.4 Performance Standards and Testing
Test results indicating dry densities less than the specified values will be rejected. Such rejected
material shall be reworked by the contractor as necessary and rerolled until a dry density equal to
or greater than the specified percent of standard Proctor maximum density is attained. Material
that is too dry or too wet to permit bonding of layers during compaction will be rejected and shall
be reworked by the contractor until the moisture content is within the specified limits.
Reworking may include removal, re-harrowing, reconditioning, rerolling, or combinations of
these procedures.

4.4.1 Subgrade Testing
Where required, checking of compaction of compacted subgrade fill and the final subgrade
surface shall consist of a minimum of one field density test per 1,000 cubic yards of material
compacted. A minimum of two tests will be taken for each day that an applicable amount of fill
is placed in excess of 150 cubic yards. A minimum of one test per lift and at least one test for
every full shift of compaction operations will be taken.
Field density tests shall be compared with standard Proctor tests (ASTM D698 Method A or C).
Where required, standard Proctor or Maximum Index Density tests shall be conducted at a
frequency of at least one test per 5,000 cubic yards of material compacted, or when material
characteristics show significant variation.
Field density testing may be conducted with the sand cone test (ASTM D1556) or a nuclear
density gauge (ASTM D6938, or as modified by the QA Manager). Correlation of nuclear
density gauge results shall be by comparison with results from sand cone test(s) and laboratory
testing for water content(s) using the oven drying method (ASTM D2216) on similar material.
Subgrade fill will be placed in lifts not exceeding 8 inches in loose thickness. Each lift shall be
compacted to a minimum of 90 percent of standard Proctor (ASTM D698) density and within
three percent of the optimum moisture content for the material.
4.4.2 Clay Liner Testing
Material specifications for the clay liner material shall be confirmed by gradation testing
conducted by approved personnel. Testing shall consist of No. 200 sieve wash and maximum
particle size testing (ASTM D422), and Atterberg limits testing (ASTM D4318) on samples of
clay liner materials, at a frequency of at least one test per 2,500 cubic yards of fill placed, or
when material characteristics show a significant variation.
Checking of compaction of the clay liner material shall consist of a minimum of one field density
test per 500 cubic yards of material compacted. A minimum of two tests will be taken for each

White Mesa Mill Reclamation Plan

August 2015
day that an applicable amount of fill is placed in excess of 150 cubic yards. A minimum of one
test per lift and at least one test for every full shift of compaction operations will be taken.
Field density tests shall be compared with standard Proctor tests (ASTM D698 Method A or C)
on the same material. Standard Proctor tests shall be conducted at a frequency of at least one test
per 2,500 cubic yards of material compacted, or when material characteristics show significant
variation.
Field density testing may be conducted with the sand cone test (ASTM D1556) or a nuclear
density gauge (ASTM D6938, or as modified by the QA Manager). Correlation of nuclear
density gauge results shall be by comparison with results from sand cone test(s) and laboratory
testing for water content(s) using the oven drying method (ASTM D2216) on similar material.
Each lift of clay liner material shall be compacted to at least 95 percent of the maximum dry
density for the material, as determined by the standard Proctor test (ASTM D698). During
compaction, the material shall be within 2 percent above to 2 percent below optimum moisture
content for the material, as determined by the standard Proctor test. If water addition is required
to achieve this range of moisture contents, the added water shall be thoroughly mixed into the
material prior to compaction.
4.4.3 Grading Tolerances
The completed grading for the clay liner shall be within 1.0 foot (horizontally) of the lines as
designed, and within 0.1 foot (vertically) of the elevations as designed. The final surfaces shall
be smoothed to avoid abrupt changes in surface grade or areas of runoff concentration. The layer
thicknesses shall meet the required minimum thicknesses.

5.0 DISCHARGE CHANNEL GRADING
5.1 General
This section outlines specifications for the work associated with excavating the discharge
channel into competent bedrock. Portions of the grading for the sedimentation basin may be in
soil, while other areas may require rock excavation. In general, the rock is believed to be
rippable, however the Contractor should account for the possibility that harder rock may be
encountered in the excavation areas.
5.2 Work Description
5.2.1 Discharge Channel Excavation
The discharge channel shall be excavated to the slopes and grades shown on the Drawings. The
channel width(s) shall be constructed to the dimensions shown on the Drawings. The side slopes
of the channel shall be 3:1 (horizontal to vertical).
Discharge channel excavation will include breaching of the Cell 1 dike on the east side. Riprap
will not be required to armor the discharge channel when the channel excavation is into
competent sedimentary rock. The competency of the sedimentary rock must be verified in the
field by the CQA Manager.
5.2.2 Grading Tolerances
Completed grading for the sedimentation basin, in soil, shall be within 1.0 foot (horizontally) of
the lines as designed, and within 0.1 foot (vertically) of the elevations as designed. Final surfaces
shall be smoothed to avoid abrupt changes in surface grade or areas of runoff concentration.
The completed grading for the discharge channel (and portions of the sedimentation basin) in
rock shall be within 2.0 foot (horizontally) of the lines as designed, and within 0.5 foot
(vertically) of the elevations as designed. The final rock surfaces will be rough and should not be
filled to make grade. The bedrock channel should be constructed at or below the design grades
in order to meet the intent of the design.

6.0 MILL DECOMMISSIONING
The following subsections describe decommissioning plans for the mill buildings and equipment,
the mill site, and associated windblown contamination.
6.1 Mill Buildings and Equipment
The uranium and vanadium processing areas of the Mill, including all equipment, structures and
support facilities, will be decommissioned by demolition and disposed of in tailings or buried on
site as appropriate. All equipment, including tankage and piping, agitation equipment, process
control instrumentation and switchgear, and contaminated structures will be cut up, removed and
buried in tailings prior to final cover placement. Concrete structures and foundations will be
broken up and removed. Concrete foundations may be left in place and covered with soil as
appropriate.
Decommissioned areas will include, but not be limited to the following:
 Coarse ore bin and associated equipment, conveyors and structures
 Grind circuit including semi-autogeneous grind (SAG) mill, screens, pumps and cyclones
 Three pulp storage leach tanks to the east of the mill building, including all tankage,
agitation equipment, pumps and piping
 Seven leach tanks inside the main mill building, including all agitation equipment, pumps
and piping
 The counter-current decantation (CCD) circuit including all thickeners and equipment,
pumps and piping
 Uranium precipitation circuit, including all thickeners, pumps and piping
 Two yellow cake dryers and all mechanical and electrical support equipment, including
uranium packaging equipment
Page A-24
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
 Clarifiers to the west of the mill building including the preleach thickener (PLT)
 The boiler and all ancillary equipment and buildings
 The entire vanadium precipitation, drying and fusion circuit
 All external tankage not included in the previous list including reagent tanks for the
storage of acid, ammonia, kerosene, water, dry chemicals, etc. and the vanadium
oxidation circuit
 The uranium and vanadium solvent extraction (SX) circuit including all SX and reagent
tankage, mixers and settlers, pumps and piping
 The SX building
 The mill building
 The alternate feed processing circuit
 The decontamination pads
 The office building
 The shop and warehouse building
 The sample plant building
 The reagent storage building
The sequence of demolition will proceed so as to allow the maximum use of support areas of the
facility such as the office and shop areas. It is anticipated that all major structures and large
equipment will be demolished using hydraulic shears. This equipment will expedite the process,
provide proper sizing of the materials for transport and placement, and reduce exposure to
radiation and other safety hazards during the demolition. Any uncontaminated or
Page A-25
Revision 5.0
Energy Fuels Resources (USA) Inc.

August 2015
decontaminated equipment to be considered for salvage and remediation equipment will be
released in accordance with the terms of License Condition 9.10 and NUREG 1575 Supplement
1, Multi-Agency Radiation Survey and Assessment of Materials and Equipment Manual
(MARSAME) (NRC, 2009) as appropriate and applicable. Contaminated soils from the mill
area will be disposed of in the tailings cells in accordance with Section 7.0 of the Technical
Specifications.
6.2 Mill Site and Windblown Contamination
Areas with contamination around the mill site are expected to be primarily surficial and include the
ore storage area and surface contamination of some roads. All ore and alternate feed materials will
have been previously removed from the ore stockpile area. All contaminated materials will be
excavated and be disposed in one of the tailings cells in accordance with Section 7.0 of these
Technical Specifications. The depth of excavation will vary depending on the extent of
contamination and will be based on the criteria in Section 7.2.3 of these Technical Specifications.
All other 11e.(2) byproduct materials will be disposed of in the tailings cells.
As discussed in Section 6.1, as well as above, EFRI proposes to reclaim the mill and surrounding
land areas within the property boundary by excavating and placing wastes, demolition debris and
contaminated soils into a fenced and controlled permanent tailings disposal area. The permanent
tailings disposal area, the current restricted area, and the property boundary, are delineated in
Figure REC-1. EFRI proposes to survey and release all areas within the property boundary,
excluding the proposed tailings disposal area, for unrestricted use. Contaminants of concern are
Ra-226, Th-230 and natural uranium (U-nat). The evaluation and remediation will be by Ra-226,
which is the contaminant with the most restrictive cleanup standard based on the SENES
Consultants, Inc. letter to EFRI dated August 15, 2012. This letter was provided as Attachment I
to EFRI’s Supporting Documentation for Response to Utah DWMRC Interrogatory 13/1 (SENES
2012). The relationship between Ra-226 and the remaining two contaminants will be developed as
discussed in subsequent sections of this Specification. Verification of the remediation will be
established through a Wilcoxon Rank Sum (WRS) test between the study areas and local
background areas. The procedure for verification will follow guidance from NUREG 1575 Multi-
Page A-26
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
Agency Radiation Survey and Site Investigation Manual (MARSSIM) (NRC, 2000). The
procedure will include:
 Scoping and characterization surveys: soil samples will be collected to develop a
correlation between gamma radiation levels and the unity rule.
 Classification of land areas: to (MARSSIM) Class 1 through Class 3.
 Remediation of land areas driven by correlation-based prediction equation between gamma
radiation and the unity rule for multiple radionuclides.
 Final Status Survey using the Wilcoxon Rank Sum (WRS) test with local background
areas.
The procedure also follows the Data Quality Objective (DQO) process defined in the MARSSIM
Guidance, as discussed in Section 6.6, below and NUREG-1757 Volume 2 Consolidated
Decommissioning Guidance, Characterization, Survey, and Determination of Radiological Criteria
(NRC, 2006).
6.3 Scoping and Characterization Surveys
Areas contaminated through process activities or windblown contamination from the tailings
areas will be remediated to meet applicable cleanup criteria for Ra-226, Th-230, and U-nat.
Contaminated areas will be remediated such that the residual radionuclides remaining on the site,
which are distinguishable from background, will not result in a dose that is greater than that
which would result from the Ra-226 soil standard, that is, 5 pCi/g above background for the
surface 15 cm soil layer and 15 pCi/g for the subsurface 15 cm soil layer, respectively as
discussed in Section 6.6.3.3 and hereafter referred to as “5/15”.
An initial scoping survey for windblown contamination will be conducted based on analysis of
pertinent past radiometric and land use information. Operational surveys of the areas surrounding
the mill and tailings area have indicated potential windblown contamination only to the north and
east of the ore storage area, and to the southwest of Cell 3. The initial scoping survey will be
conducted using calibrated gamma radiation instruments on 15 meter (15 m) transects.
Additional surveys will be conducted in a halo, or buffer zone, around the projected impact area.
Page A-27
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
The survey in the halo will be conducted using 25 m transects. Areas where no readings exceed
75 percent of the gamma radiation guideline value, as developed per Section 6.3.2, will be
classified as unaffected, and will not require remediation. Areas where one or more readings
exceed the gamma radiation guideline value will be further investigated to determine whether or
not remediation is required.
Prior to initiating cleanup of windblown contamination, a statistically-based soil sampling
program will be conducted in an area within or outside the property boundary that is similar to
the areas to be remediated, to determine the average background Ra-226 concentration, or
concentrations, to be ultimately used for the cleanup. Similarity, or representativeness, will be
determined based on geology, soil type and soil chemistry.
Soil cleanup verification will be accomplished by use of calibrated gamma radiation instruments.
Multiple instruments will be maintained and calibrated to ensure availability and consistency
during remediation efforts (Section 6.3.4).
6.3.1 Scoping and Characterization Survey for the Subsurface
The subsurface will only be investigated in areas where the historical site assessment (HSA)
demonstrates the possibility of contamination below the surface 15 cm. This does not include
areas of windblown contamination, or the ore storage area (unless also affected by an event
demonstrated by the HSA). The method for the subsurface investigation will include boreholes
where soil sampling and downhole gamma radiation investigations may occur. This method will
be developed based on the HSA.
6.3.2 Gamma Radiation to Unity Rule Correlation
EFRI plans to use radiation measurement instrumentation for soil background analyses, unity
rule – gamma radiation correlations, verification data, and sensitivity analyses. Soil background
analyses will be completed using MARSSIM methodology for background reference areas.

Soil samples taken during characterization for correlation will be analyzed by a certified
laboratory to determine the on-site correlation between the gamma radiation readings and the
concentration of Ra-226, Th-230 and U-nat, in the samples. Samples will be taken from:
 Areas known to be contaminated with only processed uranium materials (i.e. tailings sand
and windblown contamination)
 Areas in which it is suspected that unprocessed uranium materials (i.e. ore pad and
windblown areas downwind of the ore pad) are present
The actual number of samples used will depend on the correlation of the results between gamma
radiation readings and the unity rule as discussed below. Windblown contamination to the
northeast of the mill area is primarily associated with the unprocessed ore from the ore storage
pad. The slightly larger windblown contamination area to the southwest of the mill area is
primarily associated with the processed tailings. A minimum of 35 samples of windblown
tailings (to the southwest), and 15 samples of windblown unprocessed ore materials (to the
northeast) will be collected.
Sufficient samples will be taken to ensure that prediction equations can be developed to
adequately calculate the linear regression lines and the corresponding upper and lower 95 percent
confidence levels for each of the instruments. The upper one-sided 95 percent confidence limit
will be used for the guideline value for correlation between gamma radiation readings and Ra-
226 concentration. Because the unprocessed materials are expected to have proportionally
higher values of uranium in relation to the Ra-226 and Th-230 content, the correlation to the
gamma radiation readings are expected to be slightly different than readings from areas known
to be contaminated with only processed materials. Areas expected to have contamination from
both processed and unprocessed materials will be evaluated on the more conservative
correlation, or will be excavated to the Ra-226 standard which should ensure that the uranium is
removed.
The samples will be judgmentally selected with Ra-226 concentration at three different intervals:
 Twenty-five percent of the guideline value (5 pCi/g above background)
Page A-29
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
 Approximately the guideline level (5 pCi/g)
 Approximately twice the guideline level for the area of interest
This selection will maximise the precision of the correlation relationship at 5.0 pCi/g above
background. Background Ra-226 concentrations have been gathered over a 16-year period at
sample station BHV-3 located upwind and 5 miles west of the mill. The Ra-226 background
concentration from this sampling location is 0.93 pCi/g. This value and the concentrations of U-
nat and Th-230 assumed in equilibrium with the Ra-226 will be used as an interim value for the
background concentration used only in the initial planning for this project (e.g. use of historical
knowledge for preliminary setting of verification sample sizes). Background locations for the
verification test will have the three contaminants measured at multiple locations.
Because Ra-226 has short-lived radioactive decay products that are strong gamma radiation
emitters (namely Pb-214 and Bi-214), gamma radiation surveys can be effective for
characterizing soil Ra-226 distributions across large areas, including on relatively small spatial
scales. The well-established, effective, and widely-used analytical approach for spatially
comprehensive characterization of Ra-226 concentrations in surface soils involves spatially
intensive gamma radiation surveys combined with the use of gamma radiation and soil Ra-226
concentration correlations.
If a gamma radiation and Ra-226 concentration correlation is statistically significant, Ra-226
concentrations in surface soils can be predicted with reasonable accuracy based on gamma
radiation readings collected at a high density of measurements across large areas. The same is
true for other radionuclides, though correlative relationships tend to be less statistically
significant and estimation uncertainty can be higher. The advantage of gamma radiation surveys
is that a much higher density of measurements of terrestrial sources of gamma radiation is
possible and when combined with gamma radiation/soil radionuclide correlation analysis, the
approach produces a more comprehensive spatial characterization for comparisons against
baseline conditions and evaluation of potential radiological contamination.

Fifteen soil samples will be collected in the restricted area to establish a correlation between the
soil sampling analysis and the gamma radiation count. Additional measurement locations will be
added, if necessary, to reach suitable precision, as defined in Section 6.6.3.7. The method that
will be used in an effort to develop statistically significant gamma radiation/soil radionuclide
correlations is as follows:
1. At each correlation plot, a 100 m2 (10 m x 10 m) plot for correlation measurements
and soil sampling will be established with pin flags. A gamma radiation scan will be
performed across each correlation plot (5 m transects at a detector height of 18
inches). The average gamma radiation reading (e.g. cpm) from scan data across each
correlation plot will be calculated and recorded in the field logbook, or developed
using data collected from the gamma radiation scan. See Figure A-1 for the scan path.
2. Within each 10 m x 10 m, correlation plot nine sub samples of surface soils, one in
the center, and eight against the edges of the plot, will be collected across the plot (at
a depth of 15 cm) and composited into a single sample to represent average soil
radionuclide characteristics across the correlation plot. Composite surface soil
samples from each correlation plot will be submitted to a qualified commercial
laboratory for analysis of U-nat, Ra-226, Th-230, Th-232 (by Ra-228), and K-40.
The correlation plot scanning and sampling design for each location is illustrated in
Figure A-1.
3. The laboratory chain of custody/analysis request form to be submitted with composite
correlation plot soil samples will specify the following requirements:
a. Thorough homogenization of each sample at the laboratory.
b. Ra-226 analysis by EPA Method 901.1, modified for soil samples, with
sample counting to be performed at least 21 days after sealing in the counting
tin to ensure full ingrowth of Rn-222 and its decay products. Analysis of K-
40 will also be conducted with EPA method 901.1, as will analysis of Ra-228
(to determine Th-232 concentrations under the assumption of radiological
equilibrium).

c. U-nat analysis by EPA Method 200.8 (ICP-MS) or equivalent, preferably with
soil matrix digestion using EPA Method 3052 (microwave assisted acid
digestion). EPA Method 3050B or equivalent digestive methods may
alternatively be used, however digestion will not be as complete.
d. Th-230 analysis by EPA Method 200.8 (ICP-MS) or equivalent, preferably
with soil matrix digestion using EPA Method 3052 (microwave assisted acid
digestion). Ten percent of the correlation plot samples will also be analyzed
for Th-230 by alpha spectroscopy.
4. Upon receiving soil analysis results from the laboratory, regression analysis will be
performed to determine, based on paired data from all correlation plots, if significant
statistical correlations exists between average gamma radiation readings and soil Ra-
226, U-nat, Th-230, Th-232 by Ra-228 and K-40 concentrations.

6.3.3 Area Classification
The characterization and scoping surveys will be used to classify areas as either non-impacted or
impacted areas. The impacted areas will be further classified into Classes 1-3 (NUREG 1575).
The classification of the areas will determine the rigor required to survey and release the areas.
 Class 1 areas are areas which have, or had prior to remediation, a potential for radioactive
contamination based on mill operating history, or known contamination based on
previous radiological surveys. Areas containing contamination in excess of the release
criterion, specifically the Derived Concentration Guideline Level (DCGL) associated
with the Wilcoxon Rank Sum Test (DCGLW), established by the radium benchmark dose
(RBD) approach in Section 6.6.3.3 prior to remediation should be classified as Class 1
areas. The concentration terms “DCGLW”, “release criterion”, and “unity rule”, have
been used interchangeably throughout the remainder of this Specification. However,
where a gamma radiation-based level is meant, the term “gamma guideline level” is used
specifically.
 Class 2 areas are areas which have, or had prior to remediation, a potential for radioactive
contamination or known radioactive contamination, but are not expected to exceed the
DCGLW.
 Class 3 areas are any impacted areas not expected to contain any residual radioactivity, or
are expected to contain levels of residual radioactivity at a small fraction of the DCGLW,
based on mill operating history and previous radiological surveys

6.3.4 Remediation
Remediation will only occur in survey units that cannot pass the release criterion (DCGLW).
Remediation will consist of excavation of soils and placement in the tailing cells, as stated in
Section 7.2.3, below. Remedial action support surveys will be conducted to guide the
remediation. Remedial action support surveys will be conducted in a manner similar to the Final
Status Surveys (FSSs), described in Sections 6.4 and 6.6, to ensure that the remedial action
achieves the DCGLW. Excavation will continue until the gamma radiation guideline value is
achieved for surface soils
Upon completion of remediation, gamma radiation surveys will be conducted on the excavated
area and areas surrounding the excavation.
6.4 Final Status Surveys
Areas of the site will be released through the final status survey (FSS) process (see Section 6.6).
Survey units will be released through FSS reports provided to DWMRC for each survey unit.
Survey units that require remediation will undergo the FSS process after remediation. Survey
units must meet the release criterion set forth in this section. Each survey unit that meets the
release criterion will be released, pending DWMRC approval.
6.4.1 Release Criterion
Release criteria have been established and are discussed in more detail in Section 6.6.

6.4.2 Statistical Test
The WRS test will be performed using the background reference data set and the systematic
sample data set from the survey unit under investigation. The background reference data set will
be added to the unity rule (1) prior to the statistical test being completed. The two data sets will
be derived using the weighted sum for multiple radionuclides set forth in MARSSIM:
For surface soils:

142 ሺ݌ܥ݅/݃ሻ ൅1
For instance, if the background reference area surface soil data set showed that one sample
contained 2.2 pCi/g Ra-226, 2.2 pCi/g U-nat, and 2.0 pCi/g Th-230, the sample would be
represented in the WRS data set as the following:
2.2 ሺ݌ܥ݅/݃ ܴܽ226ሻ
5 ሺ݌ܥ݅/݃ሻ ൅ 2.2 ሺ݌ܥ݅/݃ ܷ݊ܽݐሻ

46 ሺ݌ܥ݅/݃ሻ ൅1ൌ1.49
Thus, 1.49 (unitless) for this particular background sample would be used in the WRS
comparison data set for the background reference area to be compared to the survey unit data. If
this sample were from the survey unit, the value would be 0.49 (unitless).
The WRS test will be performed on the survey unit and background reference area using the
method in MARSSIM. For Class 1 to Class 3 survey units, the null hypothesis is that the survey
unit exceeds the release criterion. If the null hypothesis is rejected, the mean for the survey unit
does not exceed the DCGLW, and no area exceeds the DCGL Elevated Measurement
Comparison (DCGLEMC) then the survey unit is presumed to meet the release criterion and,
pending DWMRC approval, released.

If an area in a survey unit exceeds the DCGLW, the area of the contamination will be determined
using a mixture of soil sampling and gamma radiation surveying.
A comparison will be made to the EMC will be made to determine if the area presents a dose
equal to, or lower than, the DCGLW scenario. This determination will be completed through the
derivation of area factors based on the size of hypothetical areas of contamination. The area
factor for a contaminated area will be multiplied by the DCGLW to determine the allowable
contaminant concentration for that size of area, which still meets the unity rule. Area factors will
be determined prior to FSS’s and will be approved by DWMRC.
Areas of elevated activity that do not meet the DCGLEMC will be remediated.
6.5 Instrument Quality Assurance/Quality Control (QA/QC)
Field gamma radiation survey instrumentation will be sodium iodide (NaI) detectors. To the
extent possible, the same instruments will be use throughout the characterization, remediation
and final status survey. These instruments will be cross calibrated to allow other identical
instruments or similar instruments to be used. Individuals will be appropriately trained to use the
selected instrumentation and the instrumentation will be suitable for its intended use.
Instrumentation shall be operated in accordance with written procedures and manufacturer’s
manuals which will provide guidance to field personnel on the proper use and limitations of the
instruments.
6.5.1 Calibration
The manufacturer’s current calibration/maintenance records will be kept on site for review and
inspection for all instruments used during the survey. Past calibration records will be retained
for inclusion in the FSS report.
The records will include, at a minimum, the following:
 Equipment identification (name, model, and serial number)
 Manufacturer
 Date of calibration
Page A-37
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
 Calibration due date
Instrumentation must be maintained and calibrated to manufacturer’s specifications to ensure
that required traceability, sensitivity, accuracy, and precision of the equipment/instruments are
maintained. Instruments will be maintained and calibrated in accordance with American
National Standards Institute N323A (ANSI, 1997).
6.5.2 Source and Background Checks
Prior to and after daily use, instruments will be QC-checked by comparing the instrument’s
response to a designated gamma radiation source and to ambient background. Prior to
commencement of field operations, a site reference location will be selected for the performance
of these checks. Acceptable ranges (count rate) for each instrument will be established by
performing a series of counts. The acceptable range will be + 2 sigma of the mean of the series of
counts. QC source checks will consist of one-minute integrated counts with the designated
source position in a reproducible geometry, performed at the designated location. Background
checks will be performed in an identical fashion with the source removed. Results of the
background and QC checks will be recorded in a field logbook.
Instrument response to the designated QC check source will be plotted on control charts or in
tabular form (spreadsheets) and evaluated against the average source and background readings
established at the start of the field activities. A performance criterion of +/– 2 sigma of this
average will be used as an investigation action level, and a repeat of the measurement will be
performed. A performance criterion of +/– 3 sigma of this average will be used as a failure level
requiring corrective action. Results exceeding this criterion will be investigated and appropriate
corrections to instrument readings will be made if the response is affected by factors beyond
personnel control, such as large humidity or temperature changes. The instrument(s) in question
will be removed from service while investigations and corrective actions are in progress.
Instrument response to ambient background will be used to establish a mean background
response for each instrument, to monitor gross fluctuations in background activity (e.g., from
changes in barometric pressure and other, non-contaminant related causes), and to evaluate
Page A-38
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
detector response. The background measurements are performed for the purpose of checking for
detector contamination and electronic stability (especially cabling).
Instrument response to source checks are used to prove detector efficiency and electronics
stability.
During QC checks, instruments shall be inspected for physical damage, current calibration and
erroneous readings. The individual performing these tasks shall document the results in
accordance with the instrument protocol within MARSSIM, as provided in Exhibit A-1.
Instrumentation that does not meet the specified requirements of calibration, inspection, or
response check will be removed from operation. If the instrument fails the QC response check,
any data obtained to that point, but after the last successful QC check will be considered invalid
due to potentially faulty instrumentation.
6.6 Data Quality Objectives
This plan was developed using guidance from MARSSIM was developed to ensure surveys are
conducted with the proper rigor, quality assurance, and statistical analysis to make proper decisions.
A key step in the MARSSIM process is the development of DQOs. DQOs ensure collection of data
of the right type, quality, and quantity to support decisions, the decommissioning process, and the
achievement of the desired end state. The DQOs are outlined below, and include systematic
processes to:
1) State the problem
2) Identify the goal of the characterization
3) Identify inputs to the decision
4) Define the study boundaries
5) Develop the decision rules/analytical approach
6) Define acceptable decision errors
Page A-39
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
7) Optimize the design
6.6.1 State the Problem
Ultimately, the mill will be decommissioned, the demolition and decommissioning waste disposed
in the tailings cells, and the tailings system reclaimed as approved by Utah DWMRC. The
reclamation objective is to release the mill’s land areas other than the tailings area, for unrestricted
use. Land areas may have radiological contamination from milling operations. The scanning
procedure needs to identify and distinguish areas that can be released, from areas that must be
remediated prior to being released. The data collected following excavation in remediation areas
must also be suitable for use in the final status survey (FSS) to demonstrate that the clean-up
criteria have been met.
6.6.2 Identify the Decisions
The decision process will be based on data from scoping and characterization surveys, gamma
radiation correlation, remediation and final status surveys.
Survey and sampling data will be used to:
1) Assist in classification of survey units
2) Determine areas requiring remediation
3) Develop Final Status Surveys to verify that clean-up criterion has been met
6.6.3 Identify Inputs to the Decision
6.6.3.1 Characterization and Scoping
HSAs, scoping surveys, and characterization surveys will be used to determine the extent of the
contamination as well as the presence of useable relationships/ratios between the radionuclides
of background reference areas. The presence of useable relationships will be established in
accordance with Section 4.5 of MARSSIM. Soil sampling will be conducted in the survey areas
and samples will be analyzed for U-nat, Th-230 and Ra-226.
Page A-40
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
The background must be correctly characterized and a proper background reference area chosen to
represent the background for the mill soils. This will ensure that the soil will be cleaned up to the
appropriate level. Goals of the characterization include selecting an appropriate background
reference area(s) and appropriate background(s), and correctly comparing selected background(s)
with the survey units. Multiple backgrounds may be selected for different survey units depending
on the characterization and scoping surveys in conjunction with the HSA.
From MARSSIM Section 4.5, a site background reference area should have similar physical,
chemical, geological, radiological, and biological characteristics as the survey unit being
evaluated. Background reference areas are normally selected from non-impacted areas, but are
not limited to natural areas undisturbed by human activities. In some situations, a reference area
may be associated with the survey unit being evaluated, but cannot be potentially contaminated
by site activities. For example, background measurements may be taken from core samples of a
building or structure surface, pavement, or asphalt. The selected reference areas will be
reviewed with Utah DWMRC.
Systematic soil sampling will occur prior to the FSS, and samples will be analyzed for Ra-226,
Th-230, and U-nat to determine background concentrations to be used for the cleanup. The soil
sampling to determine the average background radionuclide concentrations to ultimately be used
for the cleanup will be conducted prior to remediation. Background sampling will be conducted
in a reference area within or outside of the property boundary that is similar to the area to be
remediated.
Background reference areas will be chosen such that they are representative of the survey unit
locations but are non-impacted from site operations. Representativeness shall be determined on
the basis of geomorphology, geological, geochemical, and radiological, considerations.
6.6.3.2 Correlation
A correlation of the unity rule in the soil to the gamma radiation will be developed. This
correlation will guide remediation and excavation. This correlation is explained in Section 6.3.2.
Page A-41
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
Remediation of the soil to meet the unity rule is described in Section 6.3.4. The final status survey
reports will be the definitive source of information to describe the final impacts on the soil left by
the mill. The reports will detail how the cleanup met the Site Cleanup Criteria and show that each
survey unit meets the cleanup criteria. The FSS reports will verify that the remediation has
achieved the cleanup criteria.
6.6.3.3 Site Cleanup Criteria
The DCGLs for Ra-226 are set at 5 pCi/g for the surface 15 cm soil layer and 15 pCi/g for the
subsurface 15 cm soil layer, respectively (hereafter referred to as “5/15”) (See Attachment I for
further discussion).
The DCGLs for radionuclides other than Ra-226 are derived from doses calculated for Ra-226 at
5/15 using the same exposure scenarios as were used to estimate the dose from Ra-226 at 5/15.
This is referred to as the radium benchmark dose (RBD).
Generally, elevation of U-nat and Th-230 concentrations relative to Ra-226 is unexpected since
the contaminated materials will either be ore (which are at or near secular equilibrium) or tailings
where U-nat is reduced relative to the other uranium decay series radionuclides of interest.
Possible exceptions are:
 Areas with raffinate crystals which may have higher Th-230 concentrations compared to
Ra-226 concentrations
 Areas of spilled yellowcake product near the mill where U-nat may be elevated relative to
Ra-226
The RBD approach was applied as described in Attachment I Supporting Documentation for
Interrogatory 13/1: The Radium Benchmark Dose Approach. The RESRAD (Version 6.5) code
(Yu et al. 2001) was used to implement the RBD approach. As described in NUREG-1569 as
Appendix E (NRC 2003, a Guidance document for NRC Commission Staff on the Radium
Benchmark Dose Approach), NRC considers the RESRAD code as an acceptable code for
application of the Ra-226 benchmark dose approach. In brief, radionuclides at their respective
DCGLs result in the same benchmark dose as the Ra-226 DCGL.

The DCGLs for the radionuclides of interest for the surface and subsurface layers were
calculated and are provided in Table 6.2. The scenario is for a rancher with the doses determined
using the RESRAD Version 6.5 model. The default RESRAD dietary and inhalation data which
apply for the adult are carefully selected from literature and are already considered to represent
conservative parameter values. Details on the calculation of DCGL’s are provided in Attachment
I.

Since there is more than one radionuclide of concern, the criteria for unrestricted use is applied
using the unity rule such that the RBD is never exceeded.
In the equations below, the numerator is determined by subtracting the local background from
the sample analysis following remediation. It is possible that the background may vary between
survey units due to variation in soil types.
The unity rules are:

MARSSIM requires that the median concentration in a survey unit be demonstrably lower than
the DCGLW following remediation. This is accomplished with a WRS test between soil
concentrations in the survey unit and appropriate background reference locations. For the WRS
test, the actual concentrations are used for the survey unit rather than using the incremental
concentrations, discussed previously in Section 6.4.2.
6.6.3.4 Gamma Radiation Surveys
Gamma radiation surveys will be conducted with a GPS-integrated system using 2-inch by 2-
inch sodium iodide (NaI) detectors or the equivalent. Statistical correlations will be developed
between the radiological soil sample analysis and the gamma radiation count rate. See Section
6.4.2 for the method for development and use of the gamma radiation correlation.
With the GPS-integrated method, high density gamma radiation scanning surveys will be done
using the Ludlum 44-10 detectors at a height of 18 inches above the ground. The surveyor speed
will be approximately 0.5 m/s.
For Class 1 survey units, transects will be 5 m apart and gamma radiation scanning surveys will
continue up to 20 m outside the excavation with averages calculated on each 10-m by 10-m
block. Class 1 survey units will scanned at a density to ensure that 95 percent of the 10-m by 10-
m blocks have at least 20 gamma radiation measurements for blocks in and adjacent to the
excavation areas with measurements in at least three of the four quadrants of the 10-m by 10-m
block
The remainder of the survey area outside the remediation area will be classified as Class 2 and
will be surveyed at 10 m transects. The requirement for the remainder of the survey area, Class 2,
will be that 95 percent of the blocks have at least 10 gamma radiation measurements.
The Class 3 area will include the buffer areas outside the area of contamination, and this area
will be surveyed with planned transects of 50 m. Twenty percent or more of the 10 m by 10 m
blocks will have at least 10 gamma radiation measurements.
Page A-44
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
The mean, median, and standard deviation of the 10-m by 10-m averages will be calculated by
survey unit for data logged during the scanning surveys.
6.6.3.5 Gamma Radiation Guideline Level
The average gamma radiation count rate will be established over the 10-m by 10-m blocks. A
correlation will be established between the gamma radiation level and the unity rule using co-
located gamma radiation and soil concentration measurements. The gamma radiation guideline
value will be the gamma radiation counts that equate to 0.8 (80 percent of unity rule) from the
correlation equation. Locations where the gamma radiation guideline is exceeded will have
additional gamma radiation surveys and potentially additional excavation before verification
sampling.
6.6.3.6 Selection of Verification Samples
Following completion of excavation, if necessary, verification sampling will be carried out for
each survey unit to allow a WRS test with background samples to confirm that the compliance
criteria has been met. Ten sampling blocks will be determined from a random sampling approach
for each survey unit. Following the final status gamma radiation survey, a minimum of 15 blocks
in the survey unit will be measured to confirm the gamma radiation guideline level. For these 15
samples, the five 10- by 10-m blocks with the highest average gamma radiation will be sampled
along with another 10 sample blocks randomly selected from the area.
The soil samples from the 10 randomly selected locations will be assessed to determine if the
mean concentration in the survey unit is statistically below the unity rule with an alpha error of
0.05 using the MARSSIM WRS test.
The number of samples may be increased per Section 6.6.8.
6.6.3.7 Revision of Correlation
The verification sample measurements (soil analysis and mean gamma radiation counts) will be
compared to the correlation to determine if the correlation is statistically valid. The correlation
will be updated with the verification measurements if there is less than a 95 percent probability
Page A-45
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
(p-value of 0.05) that the random verification data is less than DCGLW. Verification
measurements (soil sample and mean gamma radiation counts) will be taken with the same
method as the correlation measurements.
6.6.3.7.1 Reporting
For each survey unit, the following will be reported:
1. Number of blocks remediated during remediation phase.
2. Number of blocks with subsequent remediation initiated by gamma radiation
measurement.
3. Gamma radiation coverage compliance (i.e. percentage of blocks meeting number of
measurement criteria).
4. Mean gamma radiation level averaged over the 10-meter by 10-meter blocks.
5. Mean and range of predicted unity rules based on gamma radiation survey.
6. Mean and range of measured unity rules based on verification sampling.
6.6.3.8 Field Data
The objectives of the survey and sampling activities are to identify the concentrations of residual
radioactive material in the survey units so that the unity rule can be evaluated. This information
will allow a determination of whether a survey unit is likely to be suitable for release. The
average soil concentrations will be evaluated to verify that each radiological DCGLW is met.
6.6.4 Define the Study Boundaries
The soil in the restricted area will be surveyed for radiological contamination of U-nat, Th-230,
and Ra-226. This does not include the tailings cells, and unrestricted areas. Survey units will be
established in the unrestricted area if, during the survey of the restricted area, contamination is
found at the boundary of the restricted area or if there is reason to believe contamination is
present in the unrestricted area.

6.6.5 Develop the Decision Rules/Analytical Approach
If soils exhibit widespread contamination above the DCGLW, then removal of the soil will be
necessary or the EMC process will need to be followed to ensure that areas of contamination will
not exceed the DCGLW following excavation.
6.6.6 Define Acceptable Decision Errors
6.6.6.1 Statistical Tests
The WRS test will be used to compare background reference areas to survey units in the
MARSSIM framework for the FSS reporting. The WRS test is a nonparametric test used to test
for a difference in values between two populations; that is, one data population is hypothesized
to consist of higher average values than the other data population.
MARSSIM suggests using the WRS test in cases where the contaminant is present in background
at a significant fraction of the DCGLW. Since the DCGL is 5 pCi/g for Ra-226 and the
background is in the order of 1 pCi/g or more for Ra-226, the WRS test is the preferred test.
The soil concentrations from the 10 randomly selected locations as defined in Section 6.6.3.6
will be assessed with the WRS test to determine if the median concentration in the survey unit is
statistically below the unity rule with an alpha error of 0.05 using the MARSSIM WRS test.
6.6.6.2 Hypothesis
The decisions necessary to determine compliance with the soil cleanup criteria are based on
precise statistical statements called hypotheses, which are tested using the data from the survey
unit
Null Hypotheses - The situation that is presumed to exist is expressed as the null hypothesis (H0),
which states “the median concentration in the survey unit exceeds the median concentration in
the background reference area by more than the DCGL.”
Alternative Hypotheses - For a given H0, there is a specified alternative hypothesis (Ha), which is
an expression of what is believed to be the situation if the null hypothesis is not true. The Ha
Page A-47
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
states “the median concentration in the survey unit does not exceed the median concentration in
the background reference area by more than the DCGL.”
These hypotheses were chosen for the following two reasons: (1) the burden of proof is placed
on the HA and, (2) the survey unit will not be released until proven to meet the cleanup criterion.
In order to pass the WRS using the above H0, the median concentration of the systematic samples
in the survey unit must be less than the DCGLW above background.
6.6.6.3 Error Types
Decision errors help to determine the number of samples required. Generally, more samples are
required to generate lower decision errors (i.e., the fewer samples, the larger the uncertainty).
The statistical acceptability decisions are designed to avoid two kinds of errors:
 Releasing a survey unit which requires additional remediation
 Remediating a survey unit which is already below the DCGLW
Two possible error types are associated with such decisions, Type I and Type II, which are
described below.
Type I – which is also referred to as a false positive, occurs when H0 is rejected when it is
actually true. The probability of a Type I error is usually denoted by . This error could result
in higher potential doses to future site occupants than prescribed by the dose-based criterion. The
maximum Type I error rate has been set at  = 0.05 (there is less than 5 percent chance of error).
Type II - which is referred to as a false negative, occurs when H0 is not rejected when it is
actually false. The probability of a Type II error is usually denoted by . Consequences of Type
II errors include unnecessary remediation expense and project delays. The Type II error rate has
been set at =0.10 (there is less than 10 percent chance of error).
Statistical correlations will be developed between the unity rule and the gamma radiation
measurements. The unity rule will be determined from measurement data for incremental
concentrations at each sample location. The correlation between the unity rule and the gamma
Page A-48
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
radiation measurement at the sample location will produce a prediction equation. MARSSIM
requires that the mean concentration in a survey unit be demonstrably lower than criteria
following remediation but does not require all sampling units, in this case the 10-m by 10-m
areas, to be lower than the criteria. The precision goal for the relationship will be that the mean
prediction uncertainty for the survey unit will be +/- 0.2 when the predicted unity rule is equal to
“1”.
Protocols will be in place to ensure decision errors are kept to a minimum. For example,
instrument quality assurance checks will be required and minimum detectable concentrations
(MDCs) will be met.
The gamma radiation survey will be limited by the minimum detectable concentration (MDC)
for the 2-inch x 2-inch sodium iodide (NaI) detector which is approximately 104 Bq/Kg (2.8
pCi/gram) for Ra-226, MARSSIM Table 6.7. This MDC is dependent on the background which
may raise or lower the MDC (NRC, 2000).

(with decay products in equilibrium)
104 2.8

6.6.7 Relative Shift and Number of Samples
The target decision errors are 0.05 and 0.10 for  and , respectively. The major contributor to
the unity rule is Ra-226 since the criterion is much lower for Ra-226 compared to U-nat and Th-
230. The lower bound of the gray region (LBGR) has been set to 0.8 as Ra-226 has a typically
concentration that is only about 25 percent of the LBGR and the uncertainty will likely be of this
order.
Page A-49
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
The preliminary estimate is that a relative shift of 2.0 based on the LBGR of 0.8 and an
uncertainty of twice the background concentration. Using Table 5.3 of MARSSIM, the required
number of samples is 8.
Should any area exceed the DCGLEMC or large areas exceed the DCGLW, remediation of the
affected areas would be completed prior to resampling.
6.6.8 Optimize the Design
Initially, gamma radiation scans will be conducted in the restricted areas of the mill site. The data
from these scans will be reviewed to determine the location of any hotspots. These hotspot
locations will be sampled to determine the activity concentrations of U-nat, Th-230, and Ra-226.
A prediction equation of the unity rule will provide the basis for scanning large areas effectively
to direct focused remediation and to ensure that the cleanup criterion is met.
The statistical test (WRS test) could fail to show that the mean is below the criterion due to the
initial number of verification samples, since there may be insufficient samples to achieve the
desired decision error rates given the characteristics of the survey unit. In cases where data
suggest that the concentration is below the criterion (e.g., the mean bases), additional samples
would reduce the decision error and potentially allow the survey unit to pass. In this case, the
mean and variability of the 10 randomly selected measurements will be used to determine
MARSSIM’s relative shift with the lower bound of the gray region equal to 0.8 of the unity rule.
The  error will be set to 5 percent and the  error set to 10 percent to determine the required
total number of samples. These samples would be collected and the WRS repeated on the larger
data set.
6.7 Soil Sampling
6.7.1 Laboratory Approval
All samples will be analyzed for radionuclide concentration (pCi/g). All analyses will be
performed by a Utah DWMRC-approved/certified laboratory and a DOE-certified, or National
Environmental Laboratory Accreditation Program (NELAP)-certified laboratory. The laboratory
Page A-50
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
shall analyze method blanks, matrix spike samples, laboratory control samples and replicates.
Typical required detection levels will be less than or equal to one tenth of the DCGL for each
radionuclide.
6.7.2 Data Validation
Laboratory analytical results from the final status survey will be validated and will be reviewed
by the data validator for the following:
 Data completeness/sample integrity
 Holding times
 Calibration
 Alpha spectroscopy tracer analysis
 Laboratory and field blanks
 Laboratory control samples
 Laboratory and field duplicates
 Alpha spectroscopy matrix spikes
 Quantitation and detection limits
 Alpha spectroscopy chemical separation specificity
 Gamma radiation spectroscopy target radionuclide list identification
 Secular equilibrium verification, and result verification
Review of these parameters serves to ensure the quality of the data with respect to:
 Precision – which is a measure of the reproducibility of an analysis under a given set of
conditions. Precision was evaluated through a review of field duplicate and laboratory
duplicate samples.
 Accuracy – which is a measure of the bias that exists in a measurement system.
Accuracy was evaluated through a review of laboratory control samples, matrix spike
samples, method blanks, and tracer recoveries.

August 2015
 Representativeness – which is a measure of the degree to which the sampling data
accurately and precisely represent site conditions. Representativeness was evaluated
through a review of raw data and through a comparison of whether the proposed scoping
survey was implemented.
 Comparability – which is a measure of the degree of confidence with which two data sets
can be compared to each other. Comparability was evaluated through an assessment of
whether appropriate and acceptable analytical methods were used.
 Completeness – which is a measure of the amount of valid data obtained.

6.8 Employee Health and Safety
Programs currently in place for monitoring of exposures to employees will remain in effect
throughout the time period during which tailings cell reclamation, mill decommissioning and
clean up of windblown contamination are conducted. This will include personal monitoring and
the ongoing bioassay program. Access control will be maintained at the Restricted Area
boundary to ensure employees and equipment are released from the site in accordance with the
current License conditions. In general, no changes to the existing programs are expected and
reclamation activities are not expected to increase exposure potential beyond current levels.
6.9 Environment Monitoring
Existing environmental monitoring programs will continue during the time period in which
reclamation and decommissioning is conducted. This includes monitoring of surface and
groundwater, airborne particulates, radon, soils and vegetation according to the existing License
conditions. In general, no changes to the existing programs are expected and reclamation
activities are not expected to increase exposure potential beyond current levels.

7.0 MATERIAL DISPOSAL
7.1 General
This section outlines work associated with placement of materials in the disposal cell and tailings
cells.
7.2 Materials Description
The types of materials to be disposed of are outlined below.
7.2.1 Raffinate Crystals
After the residual liquid in Cell 1 has been evaporated, the Contractor will remove the raffinate
crystals from Cell 1 and move them to the tailings disposal cells. The crystals are likely to have
the consistency of a granular material and have larger crystal masses that require breaking down
for loading and transport (using the loading equipment).
7.2.2 Synthetic Liner
The existing PVC liner shall be removed from Cell 1 and disposed of in the tailings disposal
area.
7.2.3 Contaminated Soils
During remediation, soils located in and around the mill site exceeding the gamma radiation
guideline value will be placed in the tailings disposal cells. Soils excavated from Cell 1 shall be
placed in the tailings disposal cells.
7.2.4 Mill Debris
The mill debris will include all equipment, including tankage and piping, agitation equipment,
process control instrumentation and switchgear, and contaminated structures; including concrete
structures and foundations, will be placed in the disposal cell.
Page A-54
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
7.3 Work Description
Materials described will be spread over the working surface as much as possible to provide
relatively uniform settlement and consolidation characteristics of the cleanup materials.
7.3.1 Raffinate Crystals
Raffinate crystals will be removed from Cell 1 and transported to the tailings cells. Placement of
the crystals will be performed as a granular fill, with care being taken to avoid nesting of large
sized material. Voids around large material will be filled with finer material or the crystal mass
will be broken down by the equipment. Actual placement procedures will be evaluated by the
QC officer during construction as crystal materials are placed in the cells and modified with the
agreement of the DWMRC.
7.3.2 Synthetic Liner
The PVC liner will be cut, folded (when necessary), removed from Cell 1, and transported to the
tailings cells. The liner material will be spread as flat as practical over the designated area.
After placement, the liner will be covered as soon as possible with at least one foot of soil,
crystals or other materials for protection against wind uplift, as approved by the CQA Manager.
7.3.3 Contaminated Soils
The extent of contamination of the mill site will be determined by gamma radiation survey as
described in Section 6. A correlation between gamma survey readings and the unity rule
concentrations will be developed. Gamma survey readings can then be used to define cleanup
areas and to monitor the cleanup. Soil sampling will be conducted to confirm that the cleanup
results in levels that meet criteria described in 7.2.3.
Where surveys indicate the above criteria have not been achieved, the soil will be removed to
meet the criteria. Soil removed from Cell 1 will be excavated and transported to the tailings
cells.

7.3.4 Mill Debris
Placed debris will be spread across the bottom of the disposal cell to avoid nesting and to reduce
the volume of voids present in the disposed mass. Stockpiled soils and/or other approved
materials will be placed over and into the scrap in sufficient amount to fill the voids between the
large pieces and the volume within the hollow pieces to form a coherent mass. It is recognized
that some voids will remain because of the scrap volume reduction specified, and because of
practical limitations of these procedures. Reasonable effort will be made to fill the voids. The
approval of the CQA Manager or a designated representative will be required for the use of
materials other than stockpiled soils for the purpose of filling voids.
7.3.5 Material Sizing and Preparation
Demolition debris to be placed in the disposal cell will consist of equipment and structural
material from facilities demolition. Demolition procedures are outlined in the Preliminary Mill
Decommissioning Plan. Because of the wide variety in shape and size of demolition debris,
material of odd shapes will be cut or dismantled, to the extent practical, prior to disposal, to
facilitate handling and placement and minimize void spaces in the disposal cell. The maximum
size of dismantled or cut materials shall not exceed 20 feet in the longest dimension and a
maximum volume of 30 cubic feet for placement in the cells. Smaller dimensions may be
necessary for loading, handling, hauling, and placement of material in the disposal cell.
The debris, after having been reduced in dimension and volume if required, will be placed in the
tailings cells as directed by the CQA Manager.
7.3.6 Incompressible Debris
Material that is not compressible (steel columns and beams, concrete, and other solid material)
shall be reduced in size for loading, hauling, and placement in the disposal cell. Incompressible
debris shall be placed, oriented, or spread in a manner that minimizes void spaces below,
between, and above these materials. Incompressible debris shall be placed on and covered with
soils or similar materials (Specification Section 7.3.3). Incompressible debris such as steel
members shall be placed in the disposal cell with the longest dimension oriented horizontally.
Page A-56
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
Thick-walled pipe, conduit, tanks, vats, pressure vessels, and other hollow materials that cannot
be crushed or dismantled shall be transported to the planned location within the disposal cell and
oriented for filling and burial. The voids on the inside of the item shall be filled with
contaminated soil, clean fill soil, or grout (controlled low-strength material, flowable fill, etc.).
Contaminated soil (Section 7.3.3) or clean fill will be placed outside of the items and compacted
with standard compaction equipment (where possible) or hand-operated equipment to the
compaction requirements in Specification Section 7.4. Several lifts of compacted contaminated
soil or clean fill may be necessary to fill around and cover these items.
For debris where internal voids cannot practically be filled with soil, a grouting program would
be initiated to pump controlled low strength material (CLSM, flowable fill) into the voids. Debris
would be grouped together and characterized as materials that would require grouting, so that a
significant volume of debris can be grouted in a single action, rather than grouting individual
lengths of pipe. Pipe sections could be stacked horizontally, or cut short enough to stand
vertically in a safe manner. Grout would then likely be batched offsite and delivered to the site
and a pump truck would likely be required to place the material within the debris, within the cell.
A soil berm would be used to contain the grout laterally around the perimeter of the selected
debris. The debris voids would be grouted, and grout would also be placed around the debris to
develop a monolithic grouted mass.
If CLSM is required for the grouting of voids that cannot be filled mechanically with soil, the
mix design for the grout should mimic, as closely as possible, the strength and hydraulic
properties of the contaminated soil that will also be used for filling voids within the debris. This
will minimize any effects of differential settlement that would result from the grout having a
higher strength and being less compressible than the surrounding soil.
The unconfined compressive strength of the CLSM should be between 30 psi (minimum) and
150 psi (maximum), and unit weights should be approximately 100 to 120 pcf.

August 2015
7.3.7 Compressible Debris
Materials that are compressible (such as thin-walled piping and thin-walled tanks) shall be
flattened or crushed in the disposal cell, prior to final placement. Flattening or crushing shall be
done with hydraulic excavator attachments, or with a dozer or other steel-tracked equipment.
These materials shall be placed in the disposal cell and spread to form a lift with a maximum
thickness of two feet. Spreading shall be done in a manner resulting in materials lying flat and
minimizing void spaces. All pipe that shall be cut into lengths of approximately 10 feet or less
for disposal. Pipe larger than 12 inches in diameter shall be longitudinally split or cut.
7.3.8 Organic Debris
The volume of organic materials (such as wood and paper) that may be prone to long-term
biodegradation within the cell is anticipated to be a small percentage of the material being
disposed. However, to limit the potential for settlement due to consolidation of organics, the
contractor shall not dispose of organic materials in any lift thicker than 12 inches. The material
shall be spread with a dozer in lifts, or thoroughly mixed with soil that will be placed around
incompressible debris, and compacted. Organics mixed with soil for spreading shall be limited
to 30 percent by volume of the mixture.
7.3.9 Soils and Similar Materials
Soils and soil-like materials to be placed in the disposal cell will be from on-site areas identified
by EFRI for excavation. Soil or soil-like material shall be placed and compacted over each lift of
debris (Section 7.2.4) or other materials in lifts not to exceed two feet in loose thickness and
compacted prior to placement of additional lifts. Soils will also be used for interim soil cover to
minimize exposure of demolition materials and other materials to air and meteoric water.
7.4 Performance Standards and Testing
7.4.1 Material Compaction – Debris Lifts
During construction, the compaction requirements for the crystals will be evaluated based on
field conditions and material quantities. The compaction requirements will be determined by the
Page A-58
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
CQA Manager and the Reclamation Project Manager or a designated representative, with the
agreement of the Owner.
The debris, contaminated soils and other materials for the first lift will be placed to a depth of up
to four feet thick, in a bridging lift, to allow access for placing and compacting equipment. The
first lift will be compacted by the tracking of heavy equipment, such as a Caterpillar D6 Dozer
(or equivalent), using at least four passes, prior to the placement of the next lift. Subsequent lifts
will not exceed 12 inches and will be compacted using a minimum of four passes with the
tracked equipment.
Soil or similar material shall be compacted with a minimum of 6 passes with self-propelled,
towed, or hand-held vibratory compaction equipment. The number of passes shall be confirmed
with actual compaction equipment on site with a field test section of soil to establish a
correlation between the field compaction method and 80 percent of maximum dry density for the
soil, as determined by the standard Proctor test (ASTM D698). During compaction, the material
shall be within 1 percent above to 4 percent below optimum moisture content for the material, as
determined by the standard Proctor test. If water addition is required to achieve this range of
moisture contents, the added water shall be thoroughly mixed into the material prior to
compaction.
The CQA technicians will monitor and approve of the final debris placement. In areas where
voids are observed during placement, the contractor shall re-excavate the area, fill any voids
encountered with soil and recompact the materials, or grout the voids. The CQA technicians will
make a recommendation to the Contractor for the implementation of a grouting program where
voids, either within a debris mass, or within a vessel, cannot be properly filled with soil using
conventional equipment.
7.4.2 Material Compaction - Disposed Materials
The upper 12 inches of the final disposed material surface shall be compacted to 90 percent of
the maximum dry density for the material, as determined by the Standard Proctor test. During
compaction, the material shall be within 1 percent above to 4 percent below optimum moisture
Page A-59
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
content for the material, as determined by the standard Proctor test. If water addition is required
to achieve this range of moisture contents, the added water shall be thoroughly mixed into the
material prior to compaction.
7.4.3 Testing Frequency
Field density tests shall be compared with standard Proctor tests (ASTM D698 Method A or C)
on the same material. Standard Proctor tests shall be conducted at a frequency of at least one test
per 5,000 cubic yards of material compacted, or when material characteristics show significant
variation.
Field density testing may be conducted with the sand cone test (ASTM D1556) or a nuclear
density gauge (ASTM D6938, or as modified by the QA Manager). Correlation of nuclear
density gauge results shall be by comparison with results from sand cone test(s) and laboratory
testing for water content(s) using the oven drying method (ASTM D2216) on similar material.
The frequency of the field density and moisture tests will be not less than one test per 1,000
cubic yards of compacted fill. A minimum of two tests will be taken for each day that an
applicable amount of fill is placed in excess of 150 cubic yards. A minimum of one test per lift
and at least one test for every full shift of compaction operations will be taken.
7.4.4 Final Slope and Grades
The final disposed material surface shall have maximum side slopes of 5:1 and a top surface
sloping in the directions and grades shown on the Drawings. The side slopes and top surface
shall be free from abrupt changes in grade or areas of runoff concentration. The final disposed
material surface shall be compacted with approved construction equipment to form a smooth
surface with uniform density for subsequent cover placement.

8.0 COVER CONSTRUCTION
8.1 General
This section outlines work associated with construction of the earthen cell cover. A multi-
layered earthen cover will be placed over tailings Cells 2, 3 and 4A and a portion of Cell 1 used
for disposal of contaminated materials (the Cell 1 Disposal Area).
8.2 Materials Description
8.2.1 Cover Random Fill
The random fill for the radon attenuation layers, and the water storage/frost protection layer will
consist of a mixture of sands and silts with varying amounts of clay.
In the initial bridging (platform) lift of the tailings, rock sizes of up to 2/3 of the thickness of the
lift will be allowed. On all other fill lifts, rock sizes will be limited to 2/3 of the lift thickness,
with at least 30 percent of the material finer than the No. 40 sieve. The portion passing the No.
40 sieve, will classify as CL, SC, ML or SM materials under the Unified Soil Classification
System. Oversized material will be controlled through selective excavation at the stockpiles and
through the utilization of a grader, bulldozer or backhoe to cull oversize materials from the fill.
The source of these materials will be on-site stockpiles from previous cell construction activities.
8.2.2 Organic Matter Amendment
Composted biosolids will be used to amend the physical and chemical properties of the water
storage/frost barrier material for plant growth (Section 8.3.7). Composted biosolids will be
added to the upper six inches of the water storage fill material at a rate of 10 tons/acre.
8.2.3 Rock Mulch
Gravel will be mixed with topsoil and placed on portions of the cover on Cells 2, 3, 4A, and 4B
top surfaces (as shown on the Drawings) for erosion protection. Rock mulch material shall be
shall be free from roots, branches, rubbish, and debris.

The rock portion of the rock mulch will consist of granular materials from approved off-site
areas. The mixture shall be 25 percent gravel by weight. The rock (gravel) portion of the rock
mulch shall be a screened product and have a D100 particle size of less than 1-inch (100 percent
passing the 1-inch sieve).
The soil portion of the rock mulch will consist of select material from the on-site topsoil borrow
area (Section 3.5).
8.2.4 Erosion Protection and Perimeter Apron Rock
Material for the perimeter apron erosion protection will consist of granular materials from
approved off-site sources. The perimeter apron rock will be placed along the toe of the disposal
cell and the tailings cells in the erosion protection areas (as shown on the Drawings). Perimeter
apron rock shall meet NRC long-term durability requirements (a rock quality designation of 65
or more).
Perimeter apron rock shall be shall be a screened product, free from roots, branches, rubbish, and
debris. The specifications as given below are for rock quality designations of 70 or higher. If
actual rock quality designation is between 65 and 69, oversizing will be required. Rock quality
designations below 65 will not be acceptable.
Designated gradations for the apron rock will be as specified on the Drawings. Apron rock will
be imported from off-site.
 Side Slope riprap shall have a minimum D50 as listed below and a minimum layer
thickness of 1.5 times the D50 or the D100 of the riprap, whichever is greater:
o 1.7 in. for non-accumulating flow side slopes

8.2.6 Topsoil
Topsoil will consist of select material from the designated, on-site topsoil borrow area (Section
3.5). The topsoil shall have a plasticity index (PI) less than 10 (%), as determined by Atterberg
limits testing.
8.3 Work Description
The contractor will place cover materials based on a schedule determined by the Owner and the
Owner’s analysis of settlement data, piezometer data and equipment mobility considerations.
The DWMRC must approve fill grades and elevations prior to placement of final cover
materials. Settlement monitoring points (both temporary and permanent) will be established and
Page A-63
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
monitored in accordance with Sections 8.3.1 to 8.3.3 of the Technical Specifications and the
Settlement Monitoring Plan approved by DWMRC for the site.
In each layer of the cover, the distribution and gradation of the materials throughout each fill
layer will be such that the fill will, as far as practicable, be free of lenses, pockets, or layers of
material differing substantially in texture, gradation or moisture content from the surrounding
material. Nesting of oversized material will be controlled through selective excavation of
stockpiled material, observation of placement by a qualified individual with authority to stop
work and reject material being placed and by culling oversized material from the fill utilizing a
grader. Successive loads of material will be placed on the fill so as to produce the best practical
distribution of material.
If the compacted surface of any layer of fill is too dry or smooth to bond properly with the layer
of material to be placed thereon, it will be moistened and/or reworked with a harrow, scarifier, or
other suitable equipment to a sufficient depth to provide relatively uniform moisture content and
a satisfactory bonding surface before the next succeeding layer of fill is placed. If the compacted
surface of any layer of fill in-place is too wet, due to precipitation, for proper compaction of the
fill material to be placed thereon, the contractor will rework the material with a harrow, scarifier
or other suitable equipment to reduce the moisture content to the specified range. The contractor
will then recompact the fill.
No material will be placed when either the material being compacted, or the underlying material,
is frozen or when ambient temperatures do not permit the placement or compaction of the
materials to the specified density, without developing frost lenses in the fill.
8.3.1 Monitoring Interim Cover Settlement
The contractor will maintain the existing settlement monitoring points located within tailings
disposal cells by extending them through additional fill placement. For areas without settlement
monitoring points, the contractor will install temporary settlement points to monitor settlements
of the interim cover surface. The temporary settlement points will consist of wooden stakes,
rebar, or an approved equivalent; set a minimum of 12 inches into the interim cover surface.

Settlement data will be collected and analyzed; and the reclamation techniques and schedule will
be adjusted accordingly.
8.3.2 Monitoring Final Cover Settlement
After placement of final cover material, the contractor will install permanent settlement plates to
monitor settlement of the final cover surface. The settlement plates will consist of a corrosion
resistant steel plate (1/4-inch thick; two-foot square to which a one-inch diameter corrosion
resistant monitor pipe has been welded. The one-inch diameter monitor pipe will be surrounded
by a three-inch diameter guard pipe which will not be attached to the base plate.
The installation will consist of leveling an area on the surface and placing the base plate directly
on the cover soil. A minimum of two feet of initial soil will be placed on the base plate for a
minimum radial distance of five feet from the center pipe.
8.3.3 Monitoring Settlement Points
Settlement monument placement and data collection will be made in accordance with the
DWMRC approved Settlement Monitoring Plan.
8.3.4 Platform Layer Fill
A layer of 2.5 feet of platform fill will be placed over the tailings surface to form a stable
working platform for subsequent controlled fill placement. This platform fill will be placed by
pushing random fill material across the tailings in increments such that the underlying tailings
are displaced as little as possible. The fill soils shall be placed in lifts of 12-inch maximum loose
thickness to form a uniform subsoil layer for the cover system. A rough surface will be
maintained on the surface of each lift.
8.3.5 Highly Compacted Layer
The highly compacted layer shall be placed in lifts with maximum compacted thickness of 6
inches to form a continuous layer with a total minimum compacted layer thickness of 30 inches.

Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
achieve the required range of moisture contents, the added water shall be thoroughly mixed into
the material prior to compaction.
8.3.6 Water Storage Layer Fill Placement
Random fill will be placed to a minimum of 42 inches thick, above the highly compacted layer in
18-inch lifts. If oversized material is observed during the excavation of fill material, it will be
removed, as far as practicable, before it is placed in the fill. A rough surface will be maintained
on the surface of all but the uppermost lift. If water addition is required to achieve the required
range of moisture contents, the added water shall be thoroughly mixed into the material prior to
placement.
8.3.7 Organic Matter Amendment
Composted biosolids will be applied prior to the placement of topsoil or the topsoil-gravel
mixture. Composted biosolids will be uniformly spread over the surface of the water storage
layer (frost barrier) and mixed to a depth of 6 in. (15 cm). The soil amendment will be applied
prior to placement of the topsoil and topsoil-rock mixture.
8.3.8 Rock Mulch Placement
The contractor shall provide a method of thoroughly mixing the topsoil and the gravel mixture to
provide the 25 percent gravel- 75 percent topsoil mixture (by weight). The mixture shall be
prepared prior to transport to the placement areas. Gradation samples will be collected at the
point of placement (on the topdeck) to verify the mixture’s content. The CQA manager will
approve the contractor’s proposed method of mixing based on the gradation results during initial
placement.
The mixture shall be placed in one loose lift to form a uniform layer with a final thickness of 6
inches on the slope surfaces of the disposal cell (shown on the Drawings). The gravel-topsoil
mixture shall be spread with tracked equipment and compacted using two passes with rubber-
tracked equipment. Low-ground pressure equipment may be necessary to prevent over-
compaction of the mixture. Field density tests will be conducted to monitor and prevent
overcompaction of the material.

9.0 REVEGETATION
9.1 General
Following topsoil placement, the cover surface and other areas disturbed during reclamation
work will be revegetated. This section outlines the requirements for vegetation establishment
where required. This section may be revised as necessary based on field requirements and soil
nutrient analyses at the time of revegetation.
9.2 Materials Description
The soil amendments, seed mixture, and erosion control materials for revegetation are outlined
below. Submittals for each of the following products shall be provided to the Owner for approval
prior to use of such products.
9.2.1 Soil Amendments
The proposed application rate may be adjusted up or down based on soil chemical analysis that is
conducted prior to placement of the water storage layer.
Composted biosolids shall be added at a rate of 10 tons/acre and uniformly spread over the
surface of the water storage layer and mixed to a depth of 15 cm. This treatment will be applied
after the water storage layer is in-place and before placement of the topsoil-gravel erosion
protection layer.
9.2.2 Seed Mix
Species selection for the seed mixture was based on native vegetation found in the area as well as
soil and climatic conditions of the mill site. Changes to the seed mixture will be as approved by
EFRI. The following seed mixture shall be used on all seeded areas.

9.2.3 Erosion Control Materials
Wood fiber mulch will consist of specially prepared wood fibers and will not be produced from
recycled material such as sawdust, paper, cardboard, or residue from pulp and paper plants. The
fibers will be dyed an appropriate color, with non-toxic, water-soluble dye to facilitate visual
metering during application. Wood-fiber mulch will be supplied in packages and each package
will be marked by the manufacturer to show the air-dry weight.
A tackifier will be used with the wood-fiber mulch to improve adhesion. The tackifier will be a
biodegradable organic formulation processed specifically for the adhesive binding of mulch. In
addition, the tackifier will uniformly disperse when mixed with water and will not be detrimental
to the homogeneous properties of the mulch slurry.
9.3 Work Description
Revegetation efforts shall be directed at all reclaimed and disturbed areas. The goal of the
revegetation plan is to ensure that a self-sustaining vegetative community is established.
9.4 Soil Amendment Application
Following final placement and grading of the frost barrier layer, amendments will be applied as
discussed in Section 9.2.1. Inorganic sources of nitrogen, phosphorus, and potassium will not be
applied to the soil because composted biosolids will provide all the macronutrients required for
long-term sustainability.
9.5 Growth Zone Preparation
A favorable seedbed shall be prepared on the topsoil layer or topsoil-rock mixture, prior to
seeding operations. The soil should be loose and friable so as to maximize contact with the seed.
The soil will be tilled, following site contours with a disc or harrow (or similar approved
equipment) to a maximum depth of 6 inches. The depth of valleys and the height of ridges
caused by the final tillage operations are not to exceed 3 inches.
Page A-77
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
9.6 Seed Application
Seeding will follow the application of soil amendments and seedbed preparation, by broadcast
spreading method. This procedure will use a centrifugal type broadcaster (or similar implement),
also called an end gate seeder. The broadcasters will have a minimum effective spreading width
of 20 feet. Seed will be applied in two separate passes. One-half of the seed will be spread in
one direction and the other half of seed will be spread in a perpendicular direction. This will
ensure that seed distribution across the site is highly uniform and also provide the opportunity to
adjust the seeding rate if the specified rate is not being achieved. Seeding will not occur if wind
speeds exceed 10 mph.
Immediately following seeding, the area will be lightly harrowed to provide seed coverage and to
maximize seed-soil contact. Broadcast seed shall be harrowed into the soil to a depth of 0.25 to
0.75 inches.
Seeding will take place as soon as practical after the cover system is in place. Successful seeding
in southeastern Utah can occur either in late fall (e.g. October) as a dormant seeding, with
germination and establishment occurring the following spring or can be conducted in June, prior
to the summer monsoon season. Timing for seeding will depend upon the construction schedule
for the cover system.
9.7 Erosion Control Material Application
Mulch will be applied immediately following seeding. A weed-free, wood-fiber mulch shall be
applied to the seeded area at a minimum rate of 1.5 tons/acre. The wood-fiber mulch will be
applied by means of hydraulic equipment that utilizes water as the carrying agent. A continuous
agitator action, that keeps the mulching material and approved additives in uniform suspension,
will be maintained throughout the distribution cycle.
The pump pressure will be capable of maintaining a continuous non-fluctuating stream of slurry.
The slurry distribution lines will be large enough to prevent stoppage and the discharge line will
be equipped with a set of hydraulic spray nozzles that will provide even distribution of the mulch

slurry to the seedbed. Mulching will not be done in the presence of free surface water resulting
from rains, melting snow, or other causes. Tackifier may be added either during the
manufacturing of the mulch or incorporated during mulch application.
9.8 Performance Standard and Testing
The following section describes performance-based criteria for successful revegetation.
9.8.1 Seeding Rates
Prior to seeding, a known area will be covered with a tarp and seed will be distributed using the
broadcaster and simulating conditions that would exist under actual seeding conditions. Seed
will then be collected and weighed to determine actual seeding rate in terms of pounds per acre.
This process will be repeated until the specified seeding rate is obtained.
During the seeding process, the seeding rate will be verified at least once by comparing pounds
of seed applied to the size of the area seeded.
9.8.2 Erosion Control
The cover shall be inspected two times per year for eroded areas. Any area that has experienced
erosion shall be backfilled and reseeded. Erosion control materials shall also be reapplied over
reseeded areas.
9.8.3 Weed Control
Weed management would be conducted on the Mill site by identifying the presence of any
noxious weeds during annual vegetation surveys and developing a weed control plan that is
specific to the species that are present (Table 9.2). Noxious weed control is species-dependent
and both method and timing will vary from species to species.

Each survey will identify noxious weed populations and locate these populations on a map using
a set of symbols to identify species, size of the infestation, and density of the population. The
effectiveness of control methods will be documented in each annual survey. In addition,
immediately adjacent off-site properties will be visually surveyed to a distance of 100 feet.
Inspections will be conducted by personnel familiar with the identification of noxious weeds in
the area and based on Utah’s Noxious Weed List.

Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015

The selected control methods will be based on the type, size, and location of the mapped noxious
weeds. The treated area(s) will be monitored and re-inspected annually for new weed
introductions and to evaluate the success of the control methods. Prevention is the highest
priority weed management practice on non-infested lands; therefore protecting weed-free plant
communities is the most economical and efficient land management practice. Prevention is best
accomplished by ensuring that new weed species seed or vegetative reproductive plant parts of
weeds are not introduced into new areas, and by early detection of any new weed species before
they begin to spread.

Control methods may include chemical or mechanical approaches. The optimum method or
methods for weed management vary depending on a number of site-specific variables such as
associated vegetation, weed type, stage of growth, and severity of the weed infestation.

Chemical Control
Chemical control consists mostly of selective and non-selective herbicides. Considerations for
chemical controls include: herbicide selection, timing of application, target weed, desirable plant
species being grown or that will be planted, number of applications per year and number of years
a particular species will need to be treated for desired control. Also important are the health and
safety factors involved, and the need to consider undesirable impacts. The use of herbicides will
be in compliance with all Federal and State laws on proper use, storage, and disposal. The
chemical application will be done by a licensed contractor in accordance with all applicable laws
and regulations and all label instructions will be strictly followed. Applications of herbicides

Mechanical Control
Mechanical control is the physical removal of weeds from the soil and includes tilling, mowing,
and pulling undesirable plant species. Tillage is most effective prior to seeding and establishment
of desirable vegetation. The tillage method of weed control can be effective in eliminating
noxious perennial weeds when repeated at short intervals (every 1-2 weeks) throughout the
growing season. Tillage has the drawback of indiscriminately impacting all vegetation
interspersed with weeds in established areas and can eliminate competitive, desirable vegetation
leaving behind a prime seedbed for weeds to reinvade. Mowing can be an effective method for
controlling the spread of an infestation and preventing the formation and dispersal of seeds.
Mowing is most effective on weeds which spread solely or primarily by seed. In order to achieve
this, it must be repeated at least twice during the growing season prior to, or shortly after bloom.
Also, even the most intense mowing treatment will not kill hardy perennial weeds. Additional
considerations will be made when selecting control treatments when specific situations arise
regarding type, size, and location of weed infestations. Examples of this are perennial versus
biennial, broadleaf versus grasses, noxious weeds interspersed with desirable vegetation, large
monoculture patches, or small patches requiring spot treatment.

Treatment windows schedules, based on the control methods chosen and the noxious weeds
present, will be established for each treatment area. The best time to treat perennial noxious
weeds is in the spring or fall during their active growth phase. Different species will have
different optimum treatment times even with the same type of control. Perennial weeds usually
grow vegetatively in the spring, flower and seed in late spring and early summer, enter dormancy
during the summer and actively grow again in the fall. The treatment windows selected will
depend on the species present and control methods selected.

The final preparatory step is to determine the priority for areas to be treated. Prioritization
ensures that the most important areas are dealt with at the most effective times. Important areas
of concern include areas that may transport weed seeds. These areas include ditches, roadsides,

and land equipment storage sites. Large monoculture patches are of concern wherever they occur
and would always be high priority. Also, small patches of weeds would be treated to prevent
expansion of weed populations.

Once the treatment plan is implemented, detailed records will be kept, and success or failure of
treatment will be recorded so as to eliminate unsuccessful treatments.
9.8.4 Vegetation Establishment Performance
The following Revegetation Acceptance Goals/Criteria have been adapted from the Monticello
Site and would be used at the Mill Site to determine reclamation success.
Revegetation Acceptance Goal/Criteria:
Criterion 1 Species Composition
a. The vegetative cover (the percentage of ground surface covered by live plants) shall
be composed of a minimum of five perennial grass species (at least four listed as
native), and one perennial forb species, and two shrub species listed in Table 9.1
Criterion 2 Vegetative Cover
a. Attain a minimum vegetative cover percentage of 40 percent.
b. Individual grass and forb species listed in Table 9.1 that are used to achieve the cover
criteria shall have a minimum relative cover (the cover of a plant species expressed as
a percentage of total vegetative cover) of 4 percent and a maximum relative cover of
40 percent.
c. Individual species not listed in Table 9.1 may be accepted as part of the cover criteria
if it is demonstrated that the species is native or adapted to the area and is a desirable
component of the reclaimed project site.
d. Species not listed in Table 9.1, including annual weeds or other undesirable species
such as those listed in Table 9.2, shall not count toward the minimum vegetative
cover requirement. Every attempt should be made to minimize establishment of all
non-noxious weeds.
Page A-83
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
e. Reclaimed areas shall be free of state- and county-listed noxious weeds (Table 9.2).

f. The vegetative cover shall be self-regenerating and permanent. Self-regeneration shall
be demonstrated by evidence of reproduction, such as tillers and seed production.

Criterion 3 Shrub Density
a. A minimum shrub density of 500 stems per acre.

b. Shrubs shall be healthy and have survived at least two complete growing seasons
before being evaluated against success criteria

Plant cover would be measured annually on the tailing cells for a minimum of ten years or until
the revegetation goals stated above are achieved. Cover would be measured by the point
method, using a vegetation sighting scope mounted on an adjustable tripod with a level. Cover
would be measured for each species encountered, as well as litter, rock, and bareground. Cover
measurements would be made along a minimum of ten randomly placed transects on each tailing
cell that are 100 feet long. A total of 100 points would be sited at one-foot intervals along each
transect to collect cover data in the categories of live vegetation, litter, rock, and bareground.
Sample adequacy would be determined for each tailing cell using the following formula that
identifies the minimum number of samples that are necessary to estimate the population mean at
a 90 percent level of confidence. Total live vegetation cover would be used to calculate sample
adequacy.

n = t2s2
(.10x)2

Where: n = minimum number of samples required to meet sample
adequacy requirements

Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
s2 = variance
t2 = 1.64 for 90% confidence
x = sample mean

Shrub density would be measured in belt transects placed on either side of the cover transects.
All shrubs would be counted within a three-foot wide strip or belt transect along each side of the
transect used for point cover measurements, resulting in a belt transect that is six-feet wide and
100 feet long.

In addition to the above cover sampling, annual observations would be made of overall plant
community health and sustainability. Overall health would be based on plant vigor, presence of
annual weeds, and signs of plant deficiencies or toxicities. Plant community sustainability would
be based on observations of reproduction, including both vegetative reproduction, such as
tillering, and seed production.

If revegetated areas are not making satisfactory progress in meeting revegetation goals outlined
above, then remedial actions will be implemented as needed. These actions may include
fertilization/soil amendments, reseeding, weed control, and/or erosion control depending upon
the cause of the problem that may exist and the best remediation approach to ensure plant
community success.

Daily QA/QC Checks

August 2015
1.0 INTRODUCTION
A background count rate and reliability check using a check source shall be performed daily,
prior to use, when the detector/scaler is used for counting. Background count rates and source
checks shall be input on a control chart after developing of the mean and standard deviation
(sigma) as discussed below.
2.0 QC CONTROL CHARTING
Select a background location such as an office or other location where background gamma
radiation gamma values are not expected to vary. Take ten 30-second count readings and record
them on Form 1. Using the ten readings, calculate the mean, sigma, and 2 sigma). These results
should also be recorded on Form 1.
Daily, prior to use, and at the end of surveys, perform a 30-second background and source count
at the same location and in the same configuration as the acceptable ranges were developed. If
the background or source check result exceeds a difference of two standard deviations, (2s or 2
sigma) from the mean, as shown on Figure 2, the Instrument Control Chart, re-count the
background or source, log the results, and enter the new data on the Instrument Control Chart.
Two successive background or source check counts outside the 2s Instrument Control Chart
range indicates possible problems with the detector/electronics.
Values between ± 2s of the mean net counts generally indicate normal operation of the
instrument. Values outside the mean ± 2s will occur with a frequency of less than 5 percent.
Values greater than 3s from the mean will occur with a frequency of less than one percent and
should be investigated. Two consecutive measurements outside 3s indicate problems with
equipment and require adjustments and/or repairs as necessary. The scaler shall be removed
from service and immediate notification shall be made to the RSO or designee prior to counting
any samples.
Calibrations shall be checked whenever a significant change or repair is made to the
measurement system, or when changes are detected as a result of check source measurements.

August 2015
Control charts shall be maintained to indicate instrument operability and/or malfunction
problems on a daily basis when instruments are in use. Use the attached control chart. Control
charts should be kept for both background counts and counts with a check source, such as a 5
µCi Cs-137 source.

5 CQA/CQC PROCEDURES
This section describes the CQA/CQC monitoring and testing procedures to be used during the
Reclamation Project to ensure that construction takes place in accordance with the Drawings and
Technical Specifications. Specific requirements for construction procedures and materials are
presented in the Drawings and Technical Specifications, along with criteria for site cleanup
activities.
5.1 Contractor Evaluation
Prior to construction, each Contractor will submit a summary of proposed construction methods,
equipment and testing protocols. The Construction Manager, CQA Officer, and Engineer will
review the submittal and provide approval, in writing, of the Contractor’s plans. The Contractor
may be required to modify proposed methods, equipment, or testing protocols prior to approval.
5.2 Testing Methods
Throughout the Reclamation Project, various field and laboratory testing will be conducted to
ensure that materials meet the Technical Specifications. Where applicable, testing will be
conducted in accordance with the current versions of the corresponding ASTM test procedures.
Any revisions to the testing methods will be reviewed and approved by the Engineer and the
CQA Officer prior to usage. Testing methods to be used are summarized in Table 1. The
required frequency of testing is described in the applicable Sections that follow.

White Mesa Mill Reclamation Plan

August 2015
TEST METHOD TEST STANDARD
LA Abrasion – Fine ASTM C131
Specific Gravity – Aggregate ASTM C127
Absorption – Aggregate ASTM C127
Sodium Soundness – Aggregate ASTM C88

During earthwork operations and fill placement, testing will be conducted to verify that the
materials meet the gradation and classification specifications. Testing will include gradation
testing (ASTM D422) and Atterberg Limit testing (ASTM D4318).
Moisture-density curves will be developed using the standard Proctor test (ASTM D698). Rock
corrections (ASTM D4718) for the Proctor tests may be required depending on the material
being tested. Field density testing may be conducted with the sand cone test (ASTM D1556) or a
nuclear density gauge (ASTM D6938, or as modified by the QA Manager). Correlation of
nuclear density gauge results shall be by comparison with results from sand cone test(s) and
laboratory testing for water content(s) using the oven drying method (ASTM D2216) on similar
material. A sufficient number of sand cone tests and moisture content tests will be performed to
provide a correlation between the sand cone and nuclear density tests.
Rock protection aggregate will be tested using the LA Abrasion test for coarse or fine material
(ASTM C535 or C131), the sodium soundness test (ASTM C88), and the specific gravity and
absorption test (ASTM C127).
Other field or laboratory testing may be required throughout the Reclamation Project. Any
testing shall be performed in accordance with the applicable ASTM or other industry standard.
5.3 Cell 1 Reclamation
Reclamation of Cell 1 will include the removal of contaminated materials including raffinate
crystals, PVC liner, and contaminated site soils and the construction of a clay-lined area for
permanent disposal of contaminated site materials. This disposal area (the Cell 1 Disposal Area)
Page B-19
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
will be constructed adjacent to and parallel with the existing Cell 1 dike. A sedimentation basin
will then be constructed and a drainage channel provided.
5.3.1 Removal of Contaminated Materials
QC staff will monitor of the removal of raffinate crystals, liner, and contaminated soils from Cell
1 and placement in the designated area. QC procedures for the placement of these materials are
described in Section 5.4.
5.3.2 Subgrade Preparation
Subgrade for the clay liner may be leveled and filled as needed to provide a stable base for the
placement of the clay liner. The QC staff will monitor placement and compaction of any
subgrade fill.
5.3.3 Clay-Lined Cell 1 Disposal Area
A clay lined area will be constructed adjacent to and parallel with the existing Cell 1 dike for
permanent disposal of contaminated material and debris. Tailings will not be placed in the Cell 1
Disposal Area. The area will be lined with a 12-inch thick clay layer prior to placement of
contaminated materials and installation of the final reclamation cap. Placement of clay liner
materials will be based on a schedule determined by the availability of contaminated materials
removed from the Mill decommissioning area in order to maintain optimum moisture content of
the clay liner prior to placing of contaminated materials.
5.3.4 Clay Fill Conformance Monitoring and Testing
The CQA Contractor will perform monitoring and frequent verification testing to verify that the
clay fill meets the gradation and classification specifications. The CQA Contractor will monitor
earthmoving operations to ensure that fill material is taken from the proper borrow sources.
Clay liner material shall be minus 1-inch size, and shall be free from roots, branches, rubbish,
and process area debris. Liner material shall have a minimum of 40 percent passing the No. 200
sieve and a minimum plasticity index (PI) of 15. Suitable soils will classify as CL, CH, or SC
materials under the Unified Soil Classification System.
Page B-20
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
Gradation and classification testing will be performed at a minimum of one test per 1,000 cubic
yards of clay liner material or when the material shows significant variation. Samples should be
randomly selected for testing.
Laboratory test results for the clay liner shall be verified for compliance and approved by the
CQA site manager prior to placement of disposed materials in the cell.
5.3.5 Clay Liner and Subgrade Material Placement
QC Technicians will observe the surface condition prior to fill placement. If the compacted
surface of any layer of fill is too dry or smooth to bond properly with the layer of material to be
placed thereon, it will be moistened and/or reworked with a harrow, scarifier, or other suitable
equipment to a sufficient depth to provide relatively uniform moisture content and a satisfactory
bonding surface before the next succeeding layer of earthfill is placed. If the compacted surface
of any layer of earthfill in-place is too wet (due to precipitation) for proper compaction, it will be
reworked with harrow, scarifier or other suitable equipment to dry out the layer and reduce the
moisture content to within the required limits. It will then be recompacted to the earthfill
requirements.
QC Technicians will monitor the weather and temperature conditions. No material will be
placed when fill material or the underlying material is frozen or when ambient temperatures do
not permit the placement or compaction of the materials to the specified density without
developing frost lenses in the fill.
The QC Technicians will monitor lift thicknesses frequently to verify the specifications are being
met. The required layer and lift thicknesses for the clay liner and subgrade fill are listed in Table
2.
Table 2 - Summary of Liner Component Layers and Lift Thicknesses
Liner Component Material Type (USCS) Layer Thickness Lift Thickness

Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
5.3.6 Moisture and Density Control
The QC Technicians will monitor placement, moisture conditioning, and compaction of the fill
as it is placed. Prior to the start of field compaction operations, appropriate laboratory
compaction curves will be obtained for the range of materials to be placed. Laboratory
compaction curves based on complete Proctor tests will be obtained at the frequencies outlined in
Table 3, depending on the variability of materials being placed.
Each layer of the fill will be conditioned so that the moisture content is uniform throughout the
layer prior to and during compaction. As far as practicable, materials will be brought to the
proper moisture content before placement. If necessary, water will be added after lift placement
to the material by sprinkling on the layer. Each lift will be compacted by a sufficient number of
roller passes or other compaction equipment to achieve the required dry density. Material that is
too dry or too wet or does not meet the required dry density will be rejected and reworked until
the moisture content and dry density are within the specified limits. Reworking may include
removal, re-harrowing, reconditioning, rerolling, or combinations of these procedures.
The required density testing frequencies are included in Table 3. For all materials, a minimum of
two tests will be taken for each day that an applicable amount of fill is placed in excess of 150
cubic yards. A minimum of one test per lift and at least one test for every full shift of
compaction operations will be taken.
Field density testing may be conducted with the sand cone test (ASTM D1556) or a nuclear
density gauge (ASTM D6938, or as modified by the QA Manager). Correlation of nuclear
density gauge results shall be by comparison with results from sand cone test(s) and laboratory
testing for water content(s) using the oven drying method (ASTM D2216) on similar material. A
sufficient number of sand cone tests and moisture content tests will be performed to provide a
correlation between the sand cone and nuclear density tests. Field density tests shall be
compared with standard Proctor tests (ASTM D698 Method A or C) on the same material.
Testing frequency may be increased by the CQA Site Manager if variability of materials is noted
at the site, during adverse conditions, or to isolate failing areas of the construction.
Page B-22
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
Field density testing should not jeopardize the integrity of the clay liner. Holes in the clay
material resulting from testing should be repaired by hand by filling with clay fill, or by filling
with bentonite powder which is hydrated to fully seal the hole.

5.3.7 Sedimentation Basin and Discharge Channel
After contaminated material is removed from Cell 1 and the Cell 1 Disposal Area clay liner has
been constructed, Cell 1 will be breached and constructed as a sedimentation basin. A discharge
channel out of the sedimentation basin will be constructed. Details of these features are provided
in the Drawings and Technical Specifications. The QC staff will monitor the excavation and
construction of these features to ensure conformance with the Technical Specifications.
The channel excavation will be located within competent bedrock. The CQA team must
document and verify the competency of the sedimentary bedrock along the channel for the
Engineer and the Owner’s approval.
5.3.8 Riprap Conformance Monitoring and Testing
A rock apron will be constructed at the transition from soil to bedrock within the sedimentation
basin. Rock apron riprap material of the specified size shall have a minimum rock quality
designation or durability score of 70 or higher. If actual rock quality designation is between 65
and 69, oversizing will be required. Rock quality designations below 65 will not be acceptable.
The rock size specifications for the riprap shall be confirmed by particle-size distribution testing
prior to placement, using ASTM D422, ASTM D5519, or an approved equivalent method for
Page B-23
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
large-sized material. Testing shall be at a frequency of at least one test per 10,000 cubic yards of
riprap placed, per select size, or when riprap characteristics show significant variation.
Test series for rock durability will include specific gravity, absorption, sodium soundness and
LA abrasion. During construction additional test series and gradations will be performed for
each type of riprap when approximately one-third (1/3) and two-thirds (2/3) of the total volume
of each type have been produced or delivered. For any type of rock where the volume is greater
than 30,000 cubic yards, a test series and gradations will be performed for each additional 10,000
cubic yards of rock produced or delivered.
5.3.9 Material Placement
In subgrade areas requiring fill placement to achieve final grades, after liner removal, the upper
12 inches should be scarified, moisture conditioned and compacted prior to fill placement.
Riprap shall be placed in one or more lifts to form a continuous, uniform layer on top for the
filter material layers with a minimum thickness of 12 inches (2 times the specified D50). The top
surface of the riprap shall be track-rolled or tamped with the bucket of a track-hoe to provide a
uniform riprap surface and minimize void spaces within the riprap.
5.3.10 Tolerances
Completed grading for the sedimentation basin, in soil, shall be within 1.0 foot (horizontally) of
the lines as designed, and within 0.1 foot (vertically) of the elevations as designed. Final surfaces
shall be smoothed to avoid abrupt changes in surface grade or areas of runoff concentration.
The completed grading for the discharge channel (and portions of the sedimentation basin) in
rock shall be within 2.0 foot (horizontally) of the lines as designed, and within 0.5 foot
(vertically) of the elevations as designed. The final rock surfaces will be rough and should not be
filled to make grade. The bedrock channel should be constructed at or below the design grades
in order to meet the intent of the design.
5.3.11 Nonconformance, Corrective Action and Stop Work
The CQA staff, including the CQA Site Manager and QC Technicians, will have the authority to
reject material brought to the site or material that has been placed. For a failed field
Page B-24

moisture/density test, the QC Technician will determine the extent and depth of the affected area
and require the Contractor to re-work the material as described above. If persistent failed tests
occur (indicating inadequate compaction methods), the CQA Site Manager will have the
authority to stop the work until the underlying cause is determined and the Contractor can
demonstrate that moisture/density specifications can be met.
Laboratory test results for the clay liner shall be verified for compliance and approved by the
CQA site manager prior to placement of disposed materials in the cell.
5.3.12 Documentation
Field and laboratory test results, observations of fill placement, and field compaction test results
will be recorded using the appropriate field forms and reports, as described in Section 4. Table 4

according to the specifications and that voids are filled with stockpiled soils, contaminated soils,
tailings and/or other approved materials. The approval of the Construction Manager and CQA
Officer will be required for the use of other materials to fill voids.
A minimum of one foot of compacted soil will be required above the clay liner prior to placing
any scrap or debris.
When liner or other lightweight material is placed, the QC staff will ensure that at least one foot
of soil, crystals or other materials is placed above for protection against wind.
To the extent practicable, the various materials will not be concentrated in thick deposits on top
of the tailings, but will be spread over the working surface as much as possible to provide
relatively uniform settlement and consolidation characteristics of the cleanup materials.
It is anticipated that raffinate crystals will have a consistency similar to a granular material when
brought to the cells, with large crystal masses being broken down for transport. Placement of the
crystals will be performed as a granular fill, with care being taken to avoid nesting of large sized
material. Actual placement procedures will be evaluated by the QC staff during construction as
crystal materials are brought and placed in the cells.
Soil or soil-like material shall be placed and compacted over each lift of debris or other materials
in lifts not to exceed two feet in loose thickness and compacted prior to placement of additional
lifts.

5.4.5 Material Compaction
CQA staff will monitor material compaction to verify compliance with the specifications. The
first lift (bridging lift) will be compacted by the tracking of heavy equipment, such as a
Caterpillar D6 Dozer (or equivalent), using at least 4 passes, prior to the placement of a
subsequent lift. Contaminated soils and other cleanup materials after the bridging lift will be
compacted to the density requirement provided in the Technical Specifications. During
construction, compaction requirements for the raffinate crystals will be re-evaluated based on
field conditions and modified by the Construction Manager and CQA Officer, with the
agreement of the DWMRC personnel.
Soil or similar material shall be compacted with a minimum of six passes with self-propelled,
towed, or hand-held vibratory compaction equipment. The number of passes shall be confirmed
with actual compaction equipment on site with a field test section of soil to establish a
correlation between the field compaction method and 80 percent of maximum dry density for the
soil, as determined by the standard Proctor test (ASTM D698). During compaction, the material
shall be within 1 percent above to 4 percent below optimum moisture content for the material, as
determined by the standard Proctor test.
The upper 12 inches of the final disposed material surface shall be compacted to 90 percent of
the maximum dry density for the material, as determined by the standard Proctor test. During
compaction, the material shall be within 1 percent above to 4 percent below optimum moisture
content for the material, as determined by the standard Proctor test. If water addition is required
to achieve this range of moisture contents, the added water shall be thoroughly mixed into the
material prior to compaction.
Field density tests shall be compared with standard Proctor tests (ASTM D698 Method A or C)
on the same material. Standard Proctor tests shall be conducted at a frequency of at least one test
per 5,000 cubic yards of material compacted, or when material characteristics show significant
variation.
Page B-28
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
Field density testing may be conducted with the sand cone test (ASTM D1556) or a nuclear
density gauge (ASTM D6938, or as modified by the QA Manager). Correlation of nuclear
density gauge results shall be by comparison with results from sand cone test(s) and laboratory
testing for water content(s) using the oven drying method (ASTM D2216) on similar material. A
sufficient number of sand cone tests and moisture content tests will be performed to provide a
correlation between the sand cone and nuclear density tests.
The frequency of the field density and moisture tests will be not less than one test per 1,000
cubic yards of compacted fill. A minimum of two tests will be taken for each day that an
applicable amount of fill is placed in excess of 150 cubic yards. A minimum of one test per lift
and at least one test for every full shift of compaction operations will be taken. Tables 5 and 6
summarize the placement and testing criteria for the disposed materials.

5.4.6 Final Slope and Grades
The final disposed material surface shall have maximum side slopes of 5:1 and a top surface
sloping in the directions and grades shown on the Drawings. The side slopes and top surface
shall be free from abrupt changes in grade or areas of runoff concentration. The final disposed
material surface shall be compacted with approved construction equipment to form a smooth
surface with uniform density for subsequent cover placement.
5.4.7 Tolerances
The final surface of the disposed material shall be smoothed to avoid abrupt changes in surface
grade. The layer thicknesses shall meet the required minimum thicknesses.
5.4.8 Nonconformance, Corrective Action and Stop Work
The CQA Site Manager and QC Technicians will have the authority to reject scrap and debris
that is not properly prepared for placement. The Contractor may be required to reduce the size of
large pieces of material or pierce drums or other containers. CQ staff may also require site soils
to be re-worked if a failed test indicates the compaction requirements were not met. If persistent
inadequacies occur during the placement of contaminated materials, the CQA Site Manager will
Page B-30
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
have the authority to stop the work until the underlying cause is determined and the Contractor
can demonstrate that the specifications can be met.
5.4.9 Documentation
All observations and monitoring of contaminated material placement and all field compaction
test results will be recorded using the appropriate field forms and reports, as described in
Section 4.
5.5 Settlement Plates
The CQA team will need to verify proper construction and placement of the settlement points.
The Surveyor will conduct the settlement plate measurements based on the DWMRC approved
monitoring plan.
5.6 Cover System
A multi-layered earthen cover will be placed over tailings Cells 2, 3, 4A, and 4B and the portion
of Cell 1 used for disposal of contaminated materials (the Cell 1 Disposal Area). The cover
layers, from bottom to top, will include: 1) platform fill, 2) high compacted layer 3) water
storage layer, and 4) erosion protection layer. Layers 1 through 3 will consist of the same
material type and are all identified as “random fill”. The material specifications, layer
configurations, layer thicknesses, borrow sources, placement methods, and compaction
requirements are described in the Technical Specifications. The CQA Contractor will provide
full-time monitoring and testing during material placement.
5.6.1 Material Conformance Monitoring and Testing
The CQA Contractor will perform monitoring and frequent verification testing to ensure that the
fill materials meet the gradation and classifications specifications. The CQA Consultant will
monitor earthmoving operations to ensure that the fill material is taken from the proper borrow
sources.
Prior to the placement of the next layer of the cover, the CQA Site Manager or the QC
Technicians under the supervision of the CQA Site Manager shall inspect the completed layer
and document any of the following:
Page B-31
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
 Erosion of the layer surface
 Cracking or desiccation of the surface
 Fill areas that may contain excessive organics or other debris
 Depressions, or settlement of the layer
 Irregularities in the layer surface (e.g. grading errors)
Any documented items that constitute non-conformance with the Drawings and Technical
Specifications should be corrected prior to placement of the subsequent layer of the cover.
5.6.1.1 Random Fill
Random fill will be used for each of the lower three layers of the cover system. The fill will
consist of mixtures of sands and silts with varying amounts of clay and random amounts of
gravel and rock-size material. In the initial bridging lift of the platform fill, rock sizes of up to
2/3 of the thickness of the lift will be allowed. On all other random fill lifts, rock sizes will be
limited to 2/3 of the lift thickness, with at least 30 percent of the material finer than the No. 40
sieve. The portion passing the No. 40 sieve, will classify as CL, SC, ML or SM materials under
the Unified Soil Classification System. Oversized material will be controlled through selective
excavation at the stockpiles and through the utilization of a grader, bulldozer or backhoe to cull
oversize materials from the fill. The source of these materials will be site stockpiles from
previous cell construction activities.
Testing for all layers except the lower layer of platform fill shall consist of No. 200 sieve wash
and particle-size distribution testing (ASTM D422), and Atterberg limits (ASTM D4318) at a
frequency of at least one test per 2,000 cubic yards of fill placed, or when material characteristics
show a significant variation.
5.6.1.2 Rock Mulch
Rock mulch material shall be free from roots, branches, rubbish, and debris. The rock portion of
the rock mulch will consist of granular materials from approved off-site sources.
The mixture will be 25 percent gravel (with a D100 less than 1-inch) by weight. Rock will be
purchased from nearby commercial sources of alluvial gravel and cobbles. The rock portion of
Page B-32
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
the rock mulch shall be a screened product and have a maximum particle size of less than 1-inch.
The soil portion of the rock mulch will consist of select material from the on-site topsoil borrow
area.
Gradation specifications for the rock used for rock mulch material shall be confirmed by
gradation testing prior to mixing with the topsoil, to determine the maximum particle size.
Testing shall consist of particle-size distribution testing (ASTM D422) at a frequency of at least
one test per 2,000 cubic yards of rock delivered to the site, or when rock characteristics show a
significant variation.
Gradation specifications for rock mulch material (topsoil-gravel mixture) shall be confirmed by
gradation testing, on samples collected from the point of placement (on the topdeck). Testing
shall consist of particle-size distribution testing (ASTM D422) at a frequency of at least one test
per 2,000 cubic yards of mixture placed, or when the characteristics of the mixture show a
significant variation.
Rock mulch thickness will be controlled through establishment of grade stakes placed on a 200 x
200 foot grid on the top of the cells and by a 100 x 100 foot grid on the cell slopes. Physical
checks of rock mulch depth will be accomplished through the use of hand dug test pits at the
center of each grid in addition to monitoring the depth indicated on the grade stakes.
5.6.1.3 Topsoil
Topsoil will consist of select material from the on-site topsoil borrow area. The topsoil shall have
a plasticity index (PI) less than 10 (%), as determined by Atterberg limits testing.
Material specifications for the topsoil material shall be confirmed by Atterberg limits testing
(ASTM D4318) on samples of the topsoil, once for each 1,000 cubic yards of total topsoil
material placed (including the quantity of topsoil added to the rock mulch mixture).
5.6.2 Material Placement
QC Technicians will observe the surface condition prior to fill placement. If the compacted
surface of any layer of fill is too dry or smooth to bond properly with the layer of material to be
Page B-33
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
placed thereon, it will be moistened and/or reworked with a harrow, scarifier, or other suitable
equipment to a sufficient depth to provide relatively uniform moisture content and a satisfactory
bonding surface before the next succeeding layer of earthfill is placed. If the compacted surface
of any layer of earthfill in-place is too wet (due to precipitation) for proper compaction of the
earthfill material to be placed thereon, it will be reworked with harrow, scarifier or other suitable
equipment to reduce the moisture content to the required level. It will then be recompacted to
the earthfill requirements.
Nesting of oversized material will be controlled through selective excavation of stockpiled
material, observation of placement by QC Technicians with authority to stop work and reject
material being placed and by culling oversized material from the fill utilizing a grader.
Successive loads of material will be placed on the fill so as to produce the best practical
distribution of material.
QC Technicians will monitor the weather and temperature conditions. No material will be
placed when the fill material or the underlying material is frozen or when ambient temperatures
do not permit the placement or compaction of the materials to the specified density without
developing frost lenses in the fill.
QC Technicians will monitor and document lift thicknesses frequently to ensure the
specifications are being met. The required layer and lift thicknesses are listed in Table 7.

5.6.3 Moisture and Density Control
The QC Technicians will monitor placement, moisture conditioning, and compaction of the fill
as it is placed. Prior to the start of field compaction operations, appropriate laboratory
compaction curves will be obtained for the range of materials to be placed. Laboratory
compaction curves based on complete Proctor tests will be conducted at the frequencies outlined
in Table 8, depending on the variability of materials being placed.
Each layer of the fill will be conditioned so that the moisture content is uniform throughout the
layer prior to and during compaction. As far as practicable, materials will be brought to the
proper moisture content before placement. If necessary, water will be added after lift placement
to the material by sprinkling on the layer. Each lift will be compacted by a sufficient number of
roller passes or other compaction equipment to achieve the required dry density. Material that is
too dry or too wet or does not meet the required dry density will be rejected and will be reworked
until the moisture content and dry density are within the specified limits. Reworking may
include removal, re-harrowing, reconditioning, re-rolling, or combinations of these procedures.
The required testing frequencies are included in Table 8. For all materials (except lower layer of
platform fill at 80 percent compaction), a minimum of two tests will be taken for each day that
an applicable amount of fill is placed in excess of 150 cubic yards. A minimum of one test per
lift and at least one test for every full shift of compaction operations will be taken.

Field density testing may be conducted with the sand cone test (ASTM D1556) or a nuclear
density gauge (ASTM D6938, or as modified by the QA Manager). Correlation of nuclear
density gauge results shall be by comparison with results from sand cone test(s) and laboratory
testing for water content(s) using the oven drying method (ASTM D2216) on similar material. A
sufficient number of sand cone tests and moisture content tests will be performed to provide a
correlation between the sand cone and nuclear density tests. Field density tests shall be
compared with standard Proctor tests (ASTM D698 Method A or C) on the same material. Rock
corrections (ASTM D4718) for oversize particles may be required for the rock mulch mixture (or
other materials) depending on the gradation of the gravel material selected.
The actual frequency of testing may be increased by the CQA Site Manager if variability of
materials is noted at the site, during adverse conditions, or to isolate failing areas of the
construction.
5.6.4 Surface Slopes and Grades
The final cover surface shall have maximum side slopes of 5:1 and a top surface sloping in the
direction and grade shown on the Drawings. The side slopes and top surface shall be free from
abrupt changes in grade or areas of runoff concentration. The perimeter apron at the toe of the
side slopes shall have a minimum width of 20 feet from the toe of the side slopes and slope away
from the toe of the side slopes (as shown on the Drawings).
5.6.5 Tolerances
The completed cover surface shall be constructed to within 1.0 foot (horizontally) of the lines as
designed, and within 0.1 foot (vertically) of the elevations as designed. The final surface of the
subsoil zone shall be smoothed to avoid abrupt changes in surface grade. The layer thicknesses
shall meet the required minimum thicknesses.
5.6.6 Nonconformance, Corrective Action and Stop Work
The CQA Site Manager and QC Technicians will have the authority to reject material that is
brought to the site or material that has been placed. For a failed field moisture/density test, the
Page B-36

QC Technician will determine the extent and depth of the affected area and require the
Contractor to re-work the material as described above. If persistent failed tests occur (indicating
inadequate compaction methods), the CQA Site Manager will have the authority to stop the work
until the underlying cause is determined and the Contractor can demonstrate that the
moisture/density specifications can be met.
5.6.7 Documentation
All field and laboratory test results, observations of fill placement, and field compaction test
results will be recorded using the appropriate field forms and reports, as described in Section 4.

5.7 Rock Protection and Erosion Control
The top and side slopes of the reclaimed cover will be protected by rock surfacing. The size,
thickness and gradation requirements for the rock protection are provided in the Drawings and
Technical Specifications.
5.7.1 Material Conformance Monitoring and Testing
Riprap will be a screened product transported from gravel sources north of the project site. The
CQA Contractor will perform monitoring and frequent verification testing to confirm that the
riprap meets the gradation and durability specifications.
Page B-37
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
During active riprap placement, each load of material will be visually checked against standard
piles for gradation prior to transport to the tailings cells.
5.7.1.1 Erosion Protection and Apron Rock
Material for the perimeter aprons and slope erosion protection will consist of granular materials
from approved off-site areas. Perimeter apron rock shall meet NRC long-term durability
requirements (rock quality designation of 65 or more).
Perimeter apron rock shall be a screened product, free from roots, branches, rubbish, and debris.
The specifications as given below are for rock quality designations of 70 or higher. If actual
rock quality designation is between 65 and 69, additional oversizing will be required. Rock
quality designations below 65 will not be acceptable.
Designated gradations for the apron rock will be specified on the final drawings for construction.
Apron rock will be imported from off-site.
 Side slope riprap shall have a minimum D50 as listed below and a minimum layer
thickness of 1.5 times the D50 or the D100 of the riprap, whichever is greater:
o 1.7 in. for non-accumulating flow side slopes
o 5.3 in. for Cell 4A and Cell 4B southern side slopes
o 4.5 in. for Cell 1 Disposal Area side slope
 Rock aprons shall have a minimum D50 as listed below and a minimum layer thickness of
1.5 times the D50 or the D100 of the riprap, whichever is greater:
o 3.4 in. for Rock Apron A
o 10.5 in. for Rock Apron B
o 9.0 in. for Rock Apron C
Page B-38
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
Rock Apron C shall have a minimum D50 of 9.0. Material specifications for the perimeter apron
rock shall be confirmed by gradation testing conducted by the CQA Laboratory. Testing shall
consist of particle-size distribution testing (ASTM D422) at a frequency of at least one test per
10,000 cubic yards of rock delivered to the site, or when rock characteristics show a significant
variation.
Rock layer thickness will be controlled through establishment of grade stakes placed on a 200 x
200 foot grid on the top of the cells and by a 100 x 100 foot grid on the cell slopes. Physical
checks of riprap depth will be accomplished through the use of hand dug test pits at the center of
each grid in addition to monitoring the depth indicated on the grade stakes.
Test series for rock durability will include specific gravity, absorption, sodium soundness and
LA abrasion. During construction additional test series and gradations will be performed for
each type of riprap when approximately one-third (1/3) and two-thirds (2/3) of the total volume
of each type have been produced or delivered. For any type of rock where the volume is greater
than 30,000 cubic yards, a test series and gradations will be performed for each additional 10,000
cubic yards of rock produced or delivered. Gradations will also be performed at the direction of
the QC Technician for any locations considered inadequate based on visual inspection by the QC
Technician, or if difficulties are experienced by the Contractor during rock placement.
5.7.1.2 Erosion Protection Filter
Erosion protection filter material shall be free from roots, branches, rubbish, and debris. Filter
material will generally be classified as sand containing gravel and fines and shall meet the
following gradation specifications.

Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
Material specifications for the perimeter apron rock shall be confirmed by gradation testing
conducted by the CQA Laboratory. Testing shall consist of particle-size distribution testing
(ASTM D422) at a frequency of at least one test per 10,000 cubic yards of rock delivered to the
site, or when rock characteristics show a significant variation.
Filter layer thickness will be established during construction with grade stakes placed on a grid
or centerline and offset pattern and layer thickness marks on each grade stake. The minimum
thickness of the layer will be verified by spot checking of layer thickness by hand excavation in
selected locations.
5.7.2 Material Placement
QC Technicians will monitor riprap placement. An initial section of each type of riprap
constructed shall be visually examined and used to evaluate future placement. The initial section
will be constructed with material meeting gradation and riprap thickness requirements. Initial
testing should be conducted to determine the gradation and the rock weight/unit volume that will
be achieved in future rock placement activities. Riprap material will be hauled to the reclaimed
surfaces and placed on the surfaces using belly dump highway trucks and road graders. Riprap
will be dumped in windrows and the grader will spread the riprap in a manner to minimize
segregation of the material. Depth of placement will be controlled through the establishment of
grade stakes. Minimum required thicknesses for riprap layers are provided in Section 5.7.1.
Physical checks of riprap depth will be accomplished through the use of hand dug test pits at the
center of each grid in addition to monitoring the depth indicated on the grade stakes. The
Contractor will excavate the test pits, and QC Technicians will observe and document the
excavation. Placement of riprap will avoid accumulation of riprap sizes less than the minimum
D50 size and nesting of the larger sized rock. Additional riprap placement requirements include:
 Individual stones shall not be greater than 90 percent of the riprap layer thickness.
 Dumped riprap shall be placed to its full course thickness in one operation and in such a
manner as to avoid displacing bedding material.
Page B-40
Revision 5.0
Energy Fuels Resources (USA) Inc.
White Mesa Mill Reclamation Plan

August 2015
 Hand placement or rearrangement of individual stones will be required only to the extent
necessary to secure the results specified above. Larger stones may require individual
placement by equipment.
 Any stones that are not firmly wedged shall be adjusted and additional selected stones
inserted or existing stones replaced, so as to achieve a solid interlock.
5.7.3 Compaction
QC staff will monitor riprap placement. The riprap layer will be compacted by at least two
passes by a D7 Dozer, tamping with the bucket of a trackhoe, or equivalent methods in order to
key the rock for stability.
5.7.4 Tolerances
The completed riprap shall be placed to within 5.0 foot (horizontally) of the layout as designed,
and within 0.5 foot (vertically) of the elevations as designed. The rock layer thicknesses shall
meet the minimum requirements. Minimum required thicknesses for riprap layers are provided
in Section 5.7.1. Riprap layer thickness will be directly measured as outlined in Section 5.7.2. A
measurement device (i.e. tape measure) may be used to determine the distance from the top of
the bedding or filter layer to the top of the riprap layer.
5.7.5 Nonconformance, Corrective Action and Stop Work
The CQA Site Manager and QC Technicians will have the authority to reject riprap that is
brought to the site or riprap that has been placed. For rejected riprap, QC Technicians will
identify the extent of inadequate riprap and will require the Contractor to excavate the material
and place additional riprap. If persistent failed tests occur (indicating inadequate placement
methods), the CQA Site Manager will have the authority to stop the work until the underlying
cause is determined and the Contractor can demonstrate that the riprap can be placed according
to the specifications.
5.7.6 Documentation
All field and laboratory test results, observations of riprap placement, and field compaction test
results will be recorded using the appropriate field forms and reports, as described in Section 4.

E.1 INTRODUCTION
This appendix presents the methods, input and results of slope stability analyses of the tailings
cells at the Energy Fuels Resources (USA) Inc. (EFRI) White Mesa Uranium Mill (Mill). The Mill
is located approximately 6.0 miles south of Blanding, Utah. These analyses were conducted
according to applicable stability criteria under static and seismic conditions, including
geotechnical stability criteria in NRC (2003). These analyses are an update to the slope stability
analyses presented in MWH (2011) to incorporate revisions to the analyses to address State of
Utah, Division of Waste Management and Radiation Control (DWMRC) (formerly Utah Division
of Radiation Control, DRC) interrogatories (DRC, 2012) and review comments on EFRI
responses to 2012 interrogatories (DRC, 2013). These analyses also incorporate the revised
cover grading design, results of cover material testing conducted in 2010 and 2012
(summarized in Attachment B of EFRI, 2012), and the results of tailings testing conducted in
2013 (presented in MWH, 2015b).

Slope stability analyses were performed using limit equilibrium methods with the aid of the
computer program SLOPE/W (GEO-SLOPE, 2007). The SLOPE/W program calculates factors
of safety by any of the following methods: (1) Ordinary Fellenius, (2) Bishop’s Simplified, (3)
Janbu’s Simplified, (4) Spencer, (5) Morgenstern-Price, (6) U.S. Army Corps of Engineers, (7)
Lowe-Karafiath, and (8) Generalized Limit Equilibrium. The Morgenstern-Price method
(Morgenstern and Price, 1965) with a half-sine function for inter-slice forces was selected for
performing the computations in SLOPE/W. The method uses both circular and non-circular
shear surfaces and satisfies both moment and force equilibrium.

E.2 CRITICAL CONDITIONS AND GEOMETRY
Slope stability analyses are typically conducted for scenarios that represent the critical
conditions for post-reclamation. For the White Mesa Mill tailings cells, critical conditions for post-
reclamation were evaluated and included: (1) reclaimed outside surfaces of the embankment
with a 5H:1V slope, (2) existing inside surfaces of the embankments with a 2H:1V slope, and (3)
conservative shear strength parameters based on previous reports.

A critical cross section, cross section A, was selected through the southern dike of Cell 4A near
the southeast corner of the impoundment. The cross section location was selected based on
overall impoundment height as well as base topography and is similar to the location used for
the slope stability analyses presented in Titan (1996). The location of cross section A is shown
in Figure E.1. The tailings are planned to be dewatered prior to placement of the final portion of
cover. The phreatic surface was estimated to be five feet above the liner system for the
analyses.

A second cross section, cross section B, was selected through the northern embankment of the
Cell 1 Disposal Area. This location was chosen to address DRC interrogatories (DRC, 2012).
The location of cross section B is shown in Figure E.2. The material placed in the Cell 1
Disposal Area will include mill debris and contaminated soils. The embankment cross section
was assumed to be fully drained and therefore a phreatic surface was not included in the
analyses.

Slope stability analyses were performed by calculating factors of safety along circular and non-
circular failure surfaces for both static and pseudo-static conditions. Circular failure surface
analyses were conducted by targeting both shallow and deep failure surfaces. Block failure

surfaces through the clay liner system were evaluated for cross section B. A number of failure
surfaces were analyzed in order to calculate the factor of safety for the critical failure.

E.3 MATERIAL PROPERTIES
Material strength parameters used for the slope stability analysis are based on parameters
presented in Denison (2009) for the Cell 4B slope stability analyses conducted by Geosyntec,
historical laboratory testing on tailings and clay materials (Advanced Terra Testing, 1996; Chen
and Associates, 1987; D’Appolonia, 1982; and Western Colorado Testing, 1999), laboratory
testing conducted in 2010 and 2012 on potential cover borrow materials (see Attachment B of
EFRI, 2012), laboratory testing conducted in 2013 on tailings (MWH, 2015b) and typical
published values. The parameters for each material are discussed below and summarized in
Table E.1.

Erosion Protection: The erosion protection materials include riprap and filter material on the
embankment slopes, and rock mulch on the top surface of the cover system. Typical density
values for sand and gravel were used for the riprap and filter materials. The riprap and filter
material strength parameters were estimated based on the lower bound typical values from
Lambe (1969) for loose to medium dense sand and gravel. The rock mulch consists of topsoil
material mixed with 25 percent gravel by weight. The density of the rock mulch was based on
the 2012 laboratory testing results for topsoil (see Attachment B of EFRI, 2012) and applying a
rock correction based on 25 percent gravel by weight. The total unit weight of the rock mulch
was calculated using the estimated dry density and the long-term water content presented in the
radon analyses. Effective strength parameters of the rock mulch were estimated as an angle of
internal friction of 33 degrees and no cohesion, based on a maximum plasticity index (PI) of the
topsoil of 10 percent (listed in the specifications), and using the generalized relationship
between PI and effective angle of internal friction presented in Holtz and Kovacs (1981).

Cover System: The cover system material properties were estimated based on the updated
geotechnical site investigation in April 2012. The total unit weight values used in the model for
the random fill layers were estimated using 2010 and 2012 laboratory tests conducted on
potential cover borrow materials (see Appendix A.2) and based on the compaction effort for
each layer. The total unit weights for the cover layers were calculated using the long-term water
contents for the cover layers used in the radon analyses. Effective strength parameters for the
cover materials were estimated based on the maximum measured PI (30) from the 2010 and
2012 laboratory test results and using the generalized relationship between PI and effective
angle of internal friction presented in Holtz and Kovacs (1981), resulting in an angle of internal
friction of 29 degrees and no cohesion.

Tailings Material: The dry density of the tailings was estimated as 96 pcf, based on laboratory
tests (Chen and Associates, 1987 and Western Colorado Testing, 1999) and assuming the
upper bound long-term density of the tailings should be no greater than 90 percent of the
average laboratory measured maximum dry density for tailings. This is the same density used
for the radon analyses. The total unit weight of the tailings was calculated using the long-term
water content assumed for the tailings in the radon analyses. Based on existing operations at
the site, the tailings deposits are primarily fine sands with silt and some clay. The strength
parameters of the tailings were conservatively estimated using the Naval Design Manual for Soil
Mechanics DM7-01 (NAVFAC, 1986) as zero percent relative density silty sand. The strength
parameters used for the tailings (no cohesion and an effective angle internal friction of 25
degrees) are consistent with the values presented in Denison (2009) for the Cell 4B design
stability analyses.

Contaminated Soils/Mill Debris: The materials to be placed in the Cell 1 Disposal Area
include contaminated soils and mill debris. The contaminated soils will be from on-site and
have similar properties as the cover soils. The material properties for the contaminated soils
and mill debris were conservatively assumed to be the same as the cover soils (compacted to
85 percent standard Proctor compaction).

Clay Liner: Cell 1 will be lined with a clay liner. The dry density of the clay was estimated
based on laboratory tests performed on Section 16 clay (D’Appolonia, 1982; Advanced Terra
Testing, 1996) and assuming the clay will be compacted to 95 percent of standard Proctor
compaction. The total unit weight for the clay was calculated using the estimated dry density
and a long-term water content of 14 percent. The long-term water content was estimated based
on 15 bar water contents measured for Section 16 clay samples by Chen and Associates (1987)
presented in Titan (1996). The strength parameters for the clay were estimated using the
average measured PI (60) of samples meeting the placement specifications for minimum PI and
percent passing the No. 200 sieve, and the generalized relationship between PI and effective
angle of internal friction presented in Holtz and Kovacs (1981), resulting in an angle of internal
friction of 24 degrees and no cohesion.

Dike and Foundation: Density and strength parameters for the existing foundation and dike
material were estimated as the values presented in stability analyses performed for the design
of Cell 4B by Geosyntec (Denison, 2009). The strength parameters used in the model were
based on laboratory testing results from samples obtained from the existing berm between Cell
4A and 4B (Denison, 2009).

Bedrock: Failures are not anticipated to occur within the bedrock underlying the embankment,
due to the relatively high strength of the underlying sedimentary rock. Therefore, the material
properties for the bedrock were modelled as those consistent with sedimentary rock.

E.4 SEISMIC ANALYSIS AND SEISMICITY
Stability analyses under seismic conditions were conducted as pseudo-static analyses, where a
horizontal acceleration or seismic coefficient is applied to both cross-sections. This seismic
coefficient represents the horizontal accelerations applied on the structure by an earthquake. A
coefficient of 0.1 g was used for the analyses based on the site-specific probabilistic seismic
hazard analysis (MWH, 2015a). This seismic coefficient represents the seismic loading for the
Maximum Credible Earthquake (MCE) calculated to occur during the long-term life of the
embankment. A summary of the site seismicity is provided in the MWH (2015a).

A liquefaction analysis was conducted for the tailings and is presented in Appendix F (revised
version provided as Attachment G to this submittal). The results indicate the tailings are not
susceptible to earthquake-induced liquefaction. For materials that do not liquefy or lose shear
strength with seismic shaking, seismic slope stability is analyzed by a pseudo-static approach.
This consists of application of an equivalent horizontal acceleration or seismic coefficient to the
structure being analyzed. The seismic coefficient represents an inertial force due to strong
ground motions during the design earthquake, and is represented as a fraction of the peak
ground acceleration (PGA) at the site (typically at the base of the structure). The strategy of
representing the seismic coefficient as a fraction of the PGA has been adopted in review of
uranium tailings facility design and documented in DOE (1989). A seismic coefficient of 2/3 of
the PGA typically represents the post-reclamation conditions. MWH (2015a) estimated the
mean PGA for reclaimed conditions to be 0.15g. The seismic coefficient used for the pseudo-
static stability analysis is 0.10g (equal to 2/3 of the PGA).

E.5 DISCUSSION OF STABILITY ANALYSIS RESULTS
The results of stability analyses for Cross-section A and B are presented in Table E.2. These
values represent the lowest calculated factor of safety from a number of individual failure
surfaces for a Morgenstern-Price Analysis.

SETTLEMENT AND LIQUEFACTION ANALYSES

Updated Tailings Cover Design Report

Energy Fuels Resources (USA) Inc. MWH Americas, Inc.
F-1 August 2015
F.1 BACKGROUND

This appendix presents results of settlement analyses and evaluation of liquefaction potential of
tailings for the Energy Fuels Resources (USA) Inc. (EFRI) White Mesa Uranium Mill tailings
disposal cells. These analyses are an update to the settlement and liquefaction analyses
presented in MWH (2011) to address State of Utah, Division of Waste Management and
Radiation Control (DWMRC) (formerly Utah Division of Radiation Control, DRC) interrogatories
(DRC, 2012) and review comments on EFRI responses to 2012 interrogatories (DRC, 2013).
These analyses also incorporate (1) the revised cover grading design, (2) results of cover
material testing conducted in 2010 and 2012 (summarized in Attachment B of EFRI, 2012), (3)
results of the recent site-specific probabilistic hazard analysis (presented in MWH, 2015a), (4)
results of tailings testing conducted in 2013 (presented in MWH, 2015b), and (5) updated
calculation methods for the seismic settlement and liquefaction potential.

Settlement analyses were conducted to evaluate settlement due to placement of final cover,
dewatering of the tailings cells, long-term static (creep) settlement, and seismically induced
(seismic) settlement. The results of these analyses were used to evaluate differential
settlement and the potential for cover cracking. The settlement analyses are discussed in
Section F.2. The tailings cells were also evaluated for liquefaction potential and discussion is
provided in Section F.3.

The monolithic ET cover system evaluated in this appendix consists of the following layers from
top to bottom:

 0.5 ft (15 cm) Erosion Protection Layer (gravel-admixture)

 3.5 ft (107 cm) Water Storage/Biointrusion/Frost Protection/Radon Attenuation Layer
(loam to sandy clay)

 3.0 to 4.0 ft (91 to 122 cm) Radon Attenuation Layer (highly compacted loam to sandy
clay)

 2.5 ft (75 cm) Radon Attenuation and Grading Layer (loam to sandy clay)

F.2 SETTLEMENT ANALYSES

F.2.1 Method of Analyses

General. One-dimensional (1-D) settlement analyses were conducted for the tailings in Cells 2
and 3 to estimate total potential future settlement of the tailings after placement of the final
cover. The cone penetration testing (CPT) locations from the October 2013 tailings
investigation (MWH, 2015b) were selected as the locations for the settlement analyses. The
CPT locations are shown on Figure F.1, along with the settlement monument locations. All CPT
locations were adjacent to settlement monuments.

The settlement analyses were conducted for two time periods as described below.

1. Settlement during active maintenance. This settlement was calculated as the
settlement due to placement of the final cover and dewatering. Water levels during

active maintenance were assumed to be drawn down from water level elevations
presented in MWH (2015b) for the October 2013 tailings elevation to five feet above
the liner. EFRI proposes to dewater the tailings during active maintenance and
draw down the water levels with in Cells 2 and 3 such that there are not issues with
cover stability. This water level has been assumed as 5 feet for these analyses.
Once dewatering to this water level has been completed, remaining primary
consolidation due to placement of the cover will be very small.

2. Settlement after active maintenance. This settlement was calculated as the sum of
settlement due to creep and seismic settlement. The water level within the tailings
was assumed to be located five feet above the liner after active maintenance based
EFRI’s plan for dewatering during active maintenance for Cells 2 and 3.

1-D Column Geometry. Vertical soil profiles presented in MWH (2015b) for each CPT location
were used in the 1-D consolidation analyses, with the water levels presented in that report being
used for initial pore pressure conditions. This assumption is considered conservative since
water levels will continue to decrease due to dewatering prior to final cover placement. Cover
thicknesses are based on the cover design as listed above, with total cover thicknesses of 10.5
and 10 feet for Cells 2 and 3, respectively. The stress state for the layers within each column is
calculated at the midpoint of each tailings layer. Additional vertical column geometry details are
provided in Attachment F.1.

Total Settlement During Active Maintenance. Settlement during active maintenance is
assumed to be due to primary consolidation caused by cover loading and dewatering (i.e. creep
and initial compression are neglected). Settlement is calculated using the following equation:

Sൌ େిୌ
ଵାୣబ log ߪ’f
ߪ’i

Where:
S = settlement
Cc = compression index
H = thickness of tailings layer (ft)
ei = initial void ratio of tailings
’i = initial average effective overburden pressure (psf)
’f = final effective vertical pressure (psf)

Total Settlement After Active Maintenance. Settlement after active maintenance is
completed is assumed to be due to creep and seismic settlement.

Creep Settlement. Creep settlement was calculated using the method presented in Holtz and
Kovacs (1981) and assuming a typical value for the ratio of the secondary compression index to
the compression index (C/Cc) of 0.02 based on the upper bound average C estimated from
laboratory testing on sand-slime and slime tailings (MWH, 2015b). The secondary settlements
are based on a time period of 1,000 years.

Seismic Settlement. Seismic settlement was estimated using methods presented in Stewart et
al. (2004), and seismic parameters presented in the site-specific probabilistic seismic hazard
analysis for the site (MWH, 2015a). The mean peak ground acceleration (PGA) for reclaimed

F.2.2. Material Properties

EFRI conducted a tailings investigation of Cells 2 and 3 in October 2013 at the White Mesa Mill
site to collect site-specific tailings data to supplement existing tailings data used for the
settlement analyses. The results are presented in MWH (2015b). The tailings profiles and
properties used for the settlement analyses are based on the results presented in MWH
(2015b). Parameters used for the cover materials are based on cover material testing
conducted in 2010 and 2012 (summarized in Attachment B of EFRI, 2012). Parameters used for
the settlement analyses are summarized in Table F.1 and discussed in the following paragraph.
Additional detail on soil properties and consolidation parameters used in the analyses are
provided in Attachments F.1 through F.3.

Additional assumptions for soil parameters used in the analyses are provided below.

 For the consolidation, dewatering, and creep settlement analyses, the moist unit weight
for all tailings layers (saturated and unsaturated) was estimated as the saturated unit
weight which results in a conservative estimate of loading.
 For the consolidation, dewatering, and creep settlement analyses, properties of the
layers of tailings between the liner and the bottom of the CPT depth were estimated as
sand-slime tailings. The sand-slime tailings comprise approximately 65 percent of the
total tailings in Cells 2 and 3.
 For calculating loading conditions for seismic settlement and evaluation of liquefaction,
the moist unit weight for unsaturated tailings layers were estimated based on the long-
term moisture content of the tailings as presented in the radon emanation modeling.
 Initial stress conditions for liquefaction analyses were estimated using CPT data from
MWH (2015b) assuming the initial conditions in the future will be the same as in October
2013. This is conservative as it does not account for the effects of consolidation and
aging that will occur in the tailings during the active maintenance period. For the seismic
settlement analyses of Cell 3, the average shear wave velocities with depth measured
for Cell 2 tailings were used in the analyses to partially account for consolidation and
aging that will occur during this period. These values range from 460 to 600 feet per
second. Tailings in Cell 2 were placed earlier than Cell 3 and have been actively
dewatered since 2009. This use of the shear wave velocities measured in October 2013
is conservative for these analyses for both tailings cells since further densification of the
tailings will occur during the active maintenance period.

F.2.3 Results

As discussed previously, settlement analyses were conducted for two time periods to estimate
future settlement (1) settlement during active maintenance due to final cover placement and
dewatering, and (2) settlement after active maintenance due to creep and seismic settlement.
The results are summarized in Tables F.2 and F.3 and Figures F.2 and F.3. The spreadsheet
calculations of are provided in Attachments F.1 (settlement due to dewatering of tailings and
placement of final cover), F.2 (creep settlement), and F.3 (seismic settlement). Total settlement
during active maintenance is conservatively estimated to range from 0.9 to 1.6 feet. Total
remaining settlement due to dewatering from 5 feet above the liner to the liner is approximately
0.01 feet. Total potential future settlement due to creep is estimated to range from 0.05 to 0.09
feet, and due to seismic settlement is estimated to range from 0.23 to 0.62 feet. The total
potential future long-term settlement due to creep and seismic settlement of the tailings is
estimated to range from 0.29 to 0.71 feet. The estimates of total long term settlement were
calculated by summing the static creep settlement estimate and the seismic settlement
estimates. As such, these estimates are considered to be somewhat conservative as they are
not independent (i.e. as long-term static creep progresses, void ratio reduction will occur and
the potential for seismic settlement will reduce over time as a result).

F.2.4 Differential Settlement and Cover Cracking Potential

Differential Settlement. After placement of the final cover and during active maintenance,
additional fill may be placed in any low areas to maintain positive drainage of the cover surface.
Therefore, the critical time period where differential settlement is a concern for the cover grading
(i.e. potential for slope reversal) is after active maintenance is complete. Potential maximum
future settlement after active maintenance is estimated as 0.29 to 0.71 feet. Based on the
settlement analyses results as shown on Figure F.2, the critical location for the ratio of
maximum differential settlement over distance is estimated to occur between the CPT location
3-3S and the dike between Cells 3 and 4A (conservatively assuming no settlement of the dike
fill). Although the differential settlement is higher between CPT location 3-4N and 3-6N and the
dike between Cells 2 and 3, differential settlement at these location would result in an increase
in cover slope, therefore the former location is more critical for slope reversal. Locations on Cell
2 with higher settlement (2W4-C, 2W5-C, 2W6-S) than the 3-3S location are located within the
center of Cell 2, however the highest differential settlement associated with these points is lower
than the selected critical case.

The total potential differential settlement between 3-3S and the dike between Cells 3 and 4A is
0.50 feet over a distance of approximately 175 feet. The estimated differential settlement is
sufficiently low such that ponding and slope reversal is not expected to occur. These
calculations are based on conservative assumptions for seismic settlement with little to no credit
taken for densification of tailings prior to placement of final cover and during active maintenance
of the tailings cells. In addition, as mentioned above, creep and seismic settlement are not
independent, however they have been treated as such in the calculations. Actual differential
settlement for long-term (after active maintenance) conditions is expected to be lower.

Cover Cracking. Cover cracking analyses were performed for the highly-compacted radon
barrier. The critical location for the cover cracking analyses for maximum differential settlement
due to final cover placement, dewatering of tailings, creep, and a seismic event is 2.27 feet
between the settlement monument 3-4N and dike between Cells 2 and 3 as shown on Figure
F.3. This location has the maximum differential settlement over the shortest horizontal distance.
The maximum differential settlement, assuming there is no settlement of the dike, is 2.27 feet.
The horizontal distance between the two locations is approximately 150 feet.

Morrison-Knudsen Environmental Corporation (1993) presents a method for determining the
tensile strain required to cause cracking of the radon barrier as a function of the plasticity index
(PI) of the soil. The tensile strain at cracking is calculated by the equation below:

εf (%) = 0.05 +0.003 x (PI)

where: εf(%) = tensile strain to cause cracking of the radon barrier
PI = plasticity index of radon barrier

The PI value for the highly compacted radon attenuation layer was estimated as the weighted
average (based on soil volumes) of the measured PIs (11) for composite samples collected
during the 2010 and 2012 borrow investigations (see Attachment B of EFRI, 2012). Using this
value for PI, the minimum tensile strain that will induce cracking is 0.08 percent. The maximum
settlement-induced horizontal tensile strain on the radon attenuation layer must be less than
0.08 percent so that cover cracking will not occur.

The horizontal movement at the top of the radon barrier can be calculated based on the
following equation (Lee and Shen, 1969), which is referenced in NUREG 1620 (NRC, 2003) for
cover cracking analysis:
Hm3
2

where: m = horizontal movement in feet
H = thickness of relatively incompressible material (in this analysis H is the
thickness of the highly compacted radon barrier)
α = local slope of the settlement profile (expressed as decimal fraction)

Horizontal movement at the maximum tailing thickness is calculated to be 0.035 feet using a
maximum thickness of relatively incompressible material of 3.5 feet, and a total differential
settlement of 2.27 feet over 150 feet. The thickness of relatively incompressible material was
estimated assuming a maximum 3.5-ft highly compacted radon barrier for Cell 3. The peak
horizontal movement is assumed to be twice the average horizontal movement based on
relationships presented in Gourc et al. (2010) and Rajesh and Viswanadham (2010). The peak
horizontal movement is then calculated as 0.07.

The horizontal strain between any two settlement monitoring locations is the maximum
horizontal movement divided by the horizontal distance (0.07 ft/150 ft). Using these values, the
maximum horizontal strain is calculated as 0.05 percent. This value is lower than the maximum
allowable strain of 0.08 percent and indicates that cracking of the radon attenuation layer due to
settlement is not expected.

F.3 LIQUEFACTION ANALYSIS

F.3.1 Method of Analysis

Two procedures were used to evaluate the potential for liquefaction of the tailings based on the
results of the CPT soundings. These methods (Idriss and Boulanger, 2008; Youd et al., 2001)
are described below. The average factor of safety calculated from the two methods was used
as the factor of safety for evaluating the liquefaction potential of the tailings.

Idriss and Boulanger (2008). The Idriss and Boulanger (2008) liquefaction triggering method
estimates the cyclic stress ratio (CSR) based on the seismic design criteria and estimates the
cyclic resistance ratio (CRR) based on the CPT readings and site conditions. CSR is
calculated using a simplified procedure to estimate earthquake induced stresses, calculated
using the following relationship:

Pa: atmospheric pressure (calculated for an average elevation of 5,600 feet for the site)
M: design earthquake magnitude

The tailings pile was evaluated assuming essentially flat ground, and ignored the effects of the
slope at the edge of the tailings pile. Thus, a static shear stress correction factor of Kα=1 was
used for all calculations.

The relationship for CRR is based on liquefaction case histories and is expressed as:
Where:
qc1Ncs: equivalent clean-sand corrected normalized tip resistance

FC = Fines Content in %

The factor of safety against liquefaction was computed as:

The correlation between CSR, CRR, and qc1N is shown in Figure 67 of Idriss and Boulanger
(2008).

Youd et al. (2001). The Youd et al. (2001) liquefaction triggering method estimates the CSR
based on the seismic design criteria and estimates the CRR based on the CPT readings and
site conditions. CSR is calculated using a simplified procedure to estimate earthquake induced
stresses, calculated using the following relationship:

The correlation between CSR, CRR, and qc1N is shown in Figure 4 of Youd et al. (2001).

F.3.2. Material Properties

Liquefaction evaluation was performed for all CPT locations from the October 2013 tailings
investigation (MWH, 2015b). The liquefaction evaluation used the same assumptions for soil
profile, water table elevation, and density of the tailings material as described above for the
long-term settlement analyses. Other parameters used for the evaluation were based on CPT
data as presented in Attachment F.4 and as outlined in Idriss and Boulanger (2008) and Youd et
al. (2001). It is assumed that the compacted cover materials are not susceptible to liquefaction
and therefore were not included in the analyses.

F.3.3. Site Seismicity

Results of the site-specific probabilistic seismic hazard analysis presented in MWH (2015a)
were used in the analysis of liquefaction potential. The mean peak ground acceleration for
reclaimed (long-term) conditions is 0.15 g for an average return period of 10,000 years. The
mean seismic source is from a magnitude 5.5 event occurring 20 km from the site.

F.3.4 Results

Table F.4 presents a summary of the results of the liquefaction analysis. Further details of the
calculation can be found in Attachment F.4.

Based on the factors of safety presented in Table F.4, the tailings are judged not to be
susceptible to earthquake-induced liquefaction. The computed factors of safety against
liquefaction range from 2.0 to 2.6.

F.4 CONCLUSIONS

Evaluation total settlement due to final cover placement and dewatering indicates potential
future settlement during the active maintenance to range from approximately 0.9 to 1.6 feet.
During this time, additional fill can be placed in any low areas in order to maintain positive
drainage of the cover surface. The total predicted future long-term settlement that could occur
(due to creep and seismic settlement) after the maintenance time period is complete is
estimated to range from approximately 0.3 to 0.7 feet. The estimates of total long-term
settlement were calculated by summing the static creep settlement estimate and the seismic
settlement estimates. As such, these estimates are considered to be somewhat conservative as
they are not independent (i.e. as long-term static creep progresses, void ratio reduction will
occur and the potential for seismic settlement will reduce over time as a result). The estimated
differential settlement after completion of active maintenance is sufficiently low that slope
reversal and ponding is not expected to occur on a cover slope of 0.5 to 1.0 percent. In
addition, the results indicate that cracking of the highly-compacted radon barrier due to
settlement-induced strains is not expected. The results of the liquefaction analyses indicate the
tailings are not susceptible to earthquake-induced liquefaction.

Similar results are expected for Cells 4A and 4B. Although Cells 4A and 4B have higher tailings
thicknesses, these cells have a more effective dewatering systems and a low water level
requirement for dewatering. These cells also have a slightly steeper average cover slope
(approximately 0.8 percent) than Cells 2 and 3.

G.1 INTRODUCTION
This appendix presents the hydrologic analysis and evaluation of erosion protection for the
cover surface of the White Mesa Mill tailings disposal cells, and for the discharge channel and
sedimentation basin. These analyses are an update to the analyses presented in MWH (2011)
to incorporate revisions to the analyses to address State of Utah, Division of Waste
Management and Radiation Control (DWMRC) (formerly Utah Division of Radiation Control,
DRC) interrogatories (DRC, 2012) and review comments on EFRI responses to 2012
interrogatories (DRC, 2013). These analyses also incorporate the revised cover grading design
and results of cover material testing conducted in 2010 and 2012 (summarized in Attachment B
of EFRI, 2012). These analyses have been conducted in a manner consistent with Nuclear
Regulatory Commission (NRC) guidelines documented in NRC (1990) and Johnson (2002).
The analyses include the tasks listed below.

1. Selection of the Probable Maximum Precipitation (PMP) as the design event for the
site.
2. Calculation of the peak discharge (due to the PMP) from the surfaces of Cells 1, 2, 3,
4A and 4B for the cover surface, and for the drainage basin for the discharge
channel.
3. Evaluation of reclaimed tailings disposal cell surfaces for erosional stability (the top
surfaces and the reclaimed embankment slopes) and evaluation of the discharge
channel and sedimentation basin for erosional stability.
4. Evaluation of the need for filter material between erosional protection riprap and
underlying soil layers on the transition slopes on the top surface, the reclaimed
embankment slopes, and the rock aprons.
5. Evaluation of the need for a rock apron at the toe of the reclaimed embankment
slopes to accommodate flow transitioning from embankment slopes to native ground.
6. Evaluation of surface sheet erosion of top surface of cells due to action of surface
water and wind.

These tasks are presented in the following sections of this appendix.

G.2 CONCEPTUAL EROSIONAL PROTECTION DESIGN
Erosional protection was evaluated for the proposed monolithic ET cover design based on the
following proposed cover surface of the tailings disposal cells, as well as for the sedimentation
basin and diversion channel:

 Cells 2 and 3 top surfaces graded to 0.5 percent slope: Erosional protection is provided
by 6 inches of topsoil vegetated with a grass mixture providing poor or better vegetated
conditions with a minimum of 30 percent plant coverage (representing drought
conditions).
 Portions of Cell 1 and 2 with top surfaces graded at 1 percent slope and Cells 4A and 4B
with top surfaces at 0.8 percent slope: Erosional protection is provided by 6 inches of
topsoil mixed with 25 percent (by weight) of 1-inch minus (D100 = 1 inch) gravel,
vegetated with a grass mixture providing poor or better vegetated conditions with a
minimum of 30 percent plant coverage (representing drought conditions).

Energy Fuels Resources (USA) Inc. MWH Americas, Inc.
G-2 August 2015
 External side slopes graded to 5 horizontal to 1 vertical (5H:1V): Erosional protection is
provided by various sized angular and rounded riprap with thicknesses ranging from 6 to
8 inches and minimum D50’s ranging from 1.5 to 5.3 inches. Filter material will be placed
between the erosional protection and the underlying soil layer.
 Cover transition slopes graded to 10H:1V: Erosional protection is provided by 7 inches
of angular riprap with a minimum D50 of 4.5 inches. Filter material will be placed
between the erosional protection and the underlying soil layer.
 A rock apron at the toe of 5H:1V slopes: Erosional protection and scour protection on
the west and east sides of the cells is provided by a rock apron measuring 10.2 inches
deep and 4.25 feet in width, with a D50 of 3.4 inches. On the south side of cells 4A and
4B, and east side of Cell 4A, the rock apron measures 2.7 feet in depth, 13.2 feet in
width, and has a D50 of 10.6 inches. On the north side slope of the Cell 1 disposal area,
the rock apron measures 2.3 feet deep, 11.3 feet wide, and contains a minimum D50 of
9.0 inches.
 Sedimentation Basin area graded to 0.1 percent slope: Erosional protection is provided
by 6 inches of topsoil vegetated with a grass mixture providing poor or better vegetated
conditions with a minimum of 30 percent plant coverage (representing drought
conditions).
 Diversion Channel: The diversion channel will be excavated into bedrock.

G.3 PROBABLE MAXIMUM PRECIPITATION EVENT
As outlined in NRC (1990) and Johnson (2002), the design event for evaluation of long-term
erosional stability of the reclaimed tailings disposal cells is the PMP. The selected PMP events
used to calculate the peak discharges for evaluation of erosional stability were the six-hour
duration PMP (with a precipitation total of 9.6 inches) and the one-hour duration PMP (with a
precipitation total of 8.3 inches). These events were determined for the site area using
“Hydrometeorological Report (HMR) No. 49: Probable Maximum Precipitation Estimates,
Colorado River and Great Basin Drainages (Hansen et al. 1984) , as well as Jensen (1995).
Rainfall depth versus duration for short-term events (less than 1 hour) was developed using
procedures in HMR 49 and NUREG/CR-4620 (Nelson et al., 1986). PMP calculations were
provided in Denison (2009) and updated in Denison (2012). The calculations are provided in
Attachment G.1.

G.4 CALCULATION OF PEAK DISCHARGE
The peak discharge calculations were made using the Rational Method as described in Johnson
(2002) and Nelson et al. (1986). The time of concentration was calculated for the longest flow
path (see Figure G.1) across the tailings disposal cells using procedures by Kirpich, Soil
Conservation Service (SCS) and Brant and Oberman as presented in Nelson et al. (1986) and
DOE (1989). Equal weight was given to each of the three methods. A runoff coefficient of 1.0
was used to represent PMP conditions (DOE, 1989). These characteristics represent high
runoff quantities and peak flow velocities.

The PMP discharge results across the tailings disposal cells are presented in Table G.1. These
discharges represent flow across a unit-width across the slope.

The unit discharge values in Table G.1 above were used to evaluate the erosional stability of
the reclaimed surfaces and size erosion protection materials where necessary. These
evaluations are presented in Sections G.5 and G.6.

G.5 EROSIONAL STABILITY OF VEGETATED SLOPES
The surface of the reclaimed tailings disposal cells was evaluated for erosional stability using
the methods recommended in NRC (1990) and Johnson (2002).

Temple Method. Temple et al. (1987) outlines procedures for grass-lined channel design.
These procedures are recommended in Johnson (2002) for areas of vegetated cover and
include methods for estimating stresses on channel vegetation as well as the channel surface
soils. The evaluation for the tailings disposal cells used the peak discharge values from the
PMP (summarized in Table G.1) to conservatively represent the effective stresses from runoff
on the cover surface. The stresses on both the vegetation and the soil were evaluated.

The erosional stability of the cover surface for the tailings disposal cells was evaluated by
calculating a factor of safety against erosion due to the peak runoff from the PMP. Factor-of-
safety values were calculated as the ratio of the allowable stresses (the resisting strength of the
cover vegetation or soils) to the effective stresses (the stresses impacted by the runoff flowing
over the cover). Two factors of safety were calculated for each analysis to evaluate both the
resistance of the vegetation, and the resistance of the silty topsoil layer. The peak unit
discharge flow for the tailings disposal cells (from Table G.1) was conservatively multiplied by a
concentration factor of 3 to account for channelization of flow.

AlIowable stresses. Allowable stresses for the cover soils were calculated using the equations
in Temple et al. (1987). Material planned for the upper layer of the cover system is the on-site
stockpiled topsoil. Laboratory testing of the topsoil conducted in 2010 (see Appendix A)
indicates the topsoil classifies as either a silty clay with sand or a sandy silty clay. The D75
(diameter of which 75 percent of the material is finer) is approximately 0.08 mm to 0.1 mm (.003
in to .004 in) with a plasticity index (PI) of approximately 4 to 7. The resistance of a silty soil
with a PI less than 10 is estimated to be approximately 0.02 psf (Temple et al., 1987). For
noncohesive soils with a D75 greater than 0.05 in., the resistance is calculated as follows:

߬௔ ൌ 0.4ܦ଻ହ , for soils with D75>0.05 in,
߬௔ ൌ 0.02, for noncohesive soils with D75≤0.05 in.

Where
a = allowable shear strength (psf), and
D75 = particle diameter in which 75 percent of the soil is finer (inch).

For areas where 1-inch gravel is added to the topsoil (25 percent by weight), the D75 of the
topsoil mixture will increase to approximately 0.2 inches.

As discussed in Appendix J of this report, the cover will be vegetated with a mixture of perennial
grasses (primarily wheatgrass, ricegrass, squirreltail, and fescue) and forbs (yarrow and sage).
The allowable vegetation shear strength is calculated as:

߬௩௔ ൌ0.75ܥூ

Where
va = allowable vegetation shear strength (in psf),
CI =cover index = 2.5 [h(M)1/2]1/3,
h = stem length (ft), and
M = stem density factor (stems per square ft).

Conservatively using poor vegetation conditions, h=1.0, M=67, and CI=5.03, the resulting
vegetation shear strength value is 3.78 psf.

Effective stresses. The effective shear stress on soil due to peak runoff from the PMP was
calculated as:

߬௘ ൌߛ݀ܵ൫1െܥ௙൯ሺ݊௦/݊ሻଶ

Where
e = effective shear stress (psf),
 = unit weight of water = 62.4 pcf,
d = depth of flow (ft), from Table G.2,
S = slope of cover surface (ft/ft), from Table G.1,
Cf = cover factor (0.375 for poor vegetation),
ns = soil roughness factor (0.0156 for soils with D75≤0.05 in., or 0.0256(D75)1/6 for D75 >
0.05 in), and
n = Manning's roughness coefficient for vegetated surface.

The calculated factors of safety above show that for poor vegetation conditions, the allowable
shear strengths are equal to or higher than the effective shear stresses on both the vegetation
and the soil during peak discharge from the PMP. When vegetation conditions are good or
better, the soil factor of safety improves significantly, while the vegetation factor of safety
decreases slightly, but remains well above 1.0. Further details of calculations can be found in
Attachment G.2.

These analyses indicate that the cover on the top surface of the tailings disposal cells can be
constructed as a vegetated slope. Top slopes at 0.5 percent slopes are adequately stable
without the addition of gravel, while the 1 percent slope in Cell 2, and the 0.8 percent slope in
Cells 4A and 4B will require the addition of approximately 25 percent of 1-inch-minus gravel.

G.6 EROSIONAL STABILITY OF ROCK-PROTECTED SIDE-SLOPES
Because of the difficulty in maintaining vegetation on side slopes, the 5:1 side slopes have been
designed for erosional protection assuming vegetation is minimal. The maximum unit discharge
value from Table G.1 was used to size riprap for the embankment slopes. The Johnson and Abt

method referenced in Johnson (2002) was used for the side slopes. The required angular rock
size is calculated as follows:

ܦହ଴ ൌ5.23ܵ଴.ସଷݍௗ௘௦௜௚௡଴.ହ଺

Where
D50 = median particle diameter of which 50 percent of the soil is finer (inch),
S = slope (ft/ft), and
qdesign = design flow (cfs/ft).

Flow Characteristics. The peak unit discharge values from Table G.1 were used to represent
flow conditions across the cover surface and down the embankment side slopes south of Cells
4A and 4B. Concentration factors of 3 were used to account for channelization of flow.

Rock Characteristics. A specific gravity of 2.65 was assumed for the riprap. The overall
erosion protection design uses rounded and angular rock for the embankment side slopes.
Angular rock was selected for slopes where the required minimum D50 for rounded rock was too
large to produce. For areas where rounded rock was selected, the minimum D50 was increased
by 40 percent in the design to account for rounded rock characteristics (Abt and Johnson,
1991). The results of the riprap sizing for the embankment slopes are summarized in Table G.3
below.

Filter Requirements. NUREG-1623 (Johnson, 2002) recommends a filter or bedding layer be
placed under the erosion protection if interstitial velocities are greater than 1 ft/s, in order to
prevent erosion of the underlying soils. Bedding is not required if interstitial velocities are less
than 0.5 ft/s, and are recommended depending on the characteristics of the underlying soil if
velocities are between 0.5 and 1.0 ft/s.

Interstitial velocities are calculated by procedures presented by Abt et al. (1991) as given in the
following equation:
ܸ௜ ൌ0.23ሺ݃ൈܦଵ଴ ൈܵሻ଴.ହ

Where
Vi = interstitial velocities (ft/s),
G = acceleration due to gravity (ft/s2),
D10 = stone diameter at which 10 percent is finer (inches), and
S = gradient in decimal form.

The maximum D10 of the erosion protection is estimated based on the D50 required for erosion
protection, assuming the erosion protection will have a coefficient of uniformity (CU) of 6 and a

band width of 5. Band width refers to the ratio of the minimum and maximum allowed particle
sizes acceptable for any given percent finer designation. USDA (1994) recommends CU to be a
maximum of 6 in order to prevent gap-grading of filters. Table G.4 summarizes the results for
the side slopes.

Filter Requirement No Recommended Recommended

Based on the results in Table G.4 and the fine-grained nature of the top soil, it is recommended
that a filter be placed between the soil and the rock protection for the side slope areas that
require angular riprap. These areas include the southern side slopes of Cells 4A and 4B as well
as the northern side slope of the Cell 1 disposal area as shown in Figure G.1. The interstitial
velocity results confirm that a filter is not necessary for the non-accumulating side slopes where
rounded rock is proposed on the west and east sides of Cells 2, 3 and 4.

Gradation for proposed Filter. The procedure from USDA (1994) for determining the
gradation limits for a sand or gravel filter was used to evaluate the type of material needed to
satisfy filter requirements between the soil and rock protection for the side slopes. The method
details twelve steps to determine an appropriate gradation range for the filter layer. The steps
can be found in Chapter 26 of the USDA Handbook and are shown in the Attachment G.2 for
supporting calculations. In addition, Equation 5.3 from Cedegren (1989) and Equation 4.36 from
Nelson et al. (1986) were used to determine the filter gradation requirements. Table G.5
presents the recommended gradation.

Based on the results of Table G.5, the filter material should be a medium sand that will be
placed between the erosion protection and the base layer on the side slopes.

Sheet Erosion. The Modified Universal Soil Loss Equation (MUSLE) as presented in
NUREG/CR4620 (Nelson et al., 1986) was used to evaluate the potential for soil loss due to
sheet flows across the gravel/topsoil surface layer of the cover.

The MUSLE is defined as: ܣൌܴ∗ܭ∗ܮܵ∗ܸܯ

Where:
A = soil loss, in tons per acre per year,
R = rainfall factor,
K = soil erodibility factor,
LS = topographic factor, and
VM = dimensionless erosion factor relating to vegetative and mechanical factors

The rainfall factor, R, is 30, as given in NUREG/CR-4620 for the eastern third of Utah. The soil
erodibility factor, K, was estimated to be 0.28 for the topsoil and 0.16 for the gravel and topsoil
mixture, based on the nomograph (Fig. 5.1) in NUREG/CR-4620.

The topographic factor, LS, is calculated based on the following equation:

ଶ ∗ ൬ ܮ

௠

Where:
s = slope steepness, in percent (%),
L = slope length in feet,
m = slope steepness dependent exponent

The topographic factor was calculated using a slope of 0.82 percent and a slope length of 1,300
feet. From the Table 5.2 in NUREG/CR-4620, the slope steepness exponent, m, is 0.2 for
slopes less than or equal to 1.0 percent.

The erosion factor, VM, used was 0.4, from Table 5.3 of NUREG/CR-4620, to represent
seedlings of 0 to 60 days, to mimic light vegetation on the cover. Table G.5 summarizes the
MUSLE results for the proposed topsoil and the proposed topsoil mixed with 25 percent gravel,
by weight.

The soil loss equation shows the potential for erosion will be reduced by almost one half, by
using 25 percent gravel in the topsoil mixture. The topsoil loss of 1.5 to 3.0 inches over the life
of the cover (1,000 years) is less than the minimum design thickness of 6 inches.
G.7 ROCK SIZING FOR APRON
Additional erosion protection will be provided for runoff from the south side slopes of the
reclaimed surfaces of Cells 4A and 4B, the east side of Cell 4A, and the north side of Cell 1 with
a rock apron. The perimeter apron will: (1) serve as an impact basin and provide for energy
dissipation of runoff, (2) provide erosion protection, and (3) transition flow from side slopes to
natural ground. The median rock size required in the perimeter apron was calculated using the
equations derived by Abt et al. (1998) as outlined in NUREG 1623 (Johnson, 2002) as follows:

ܦହ଴ ௘௡௘௥௚௬ ௗ௜௦௦௜௣௔௧௜௢௡ ൌ10.46ܵ଴.ସଷݍ଴.ହ଺

Flow Characteristics. The peak unit discharge values from Table G.1 were used to represent
flow conditions down the embankment side slopes south of Cells 4A and 4B. Concentration
factors of 3 were used to account for channelization of flow.

Rock Characteristics. A specific gravity of 2.65 was assumed for the riprap. Both rounded and
angular rock was used in the apron design.

Based on the above equation, the rock apron (Apron A) along the toe of the non-accumulating
slopes covered with rounded riprap (west and east side slopes of Cells 2 and 3) should be
constructed using rounded rock with a median rock diameter of 3.4 inches. The width of the
apron should be a minimum of 15 times the median rock size (4.25 ft) and the apron thickness
should be a minimum of three times the median rock size (10.2 inches). Rock Apron B should
be placed on the toes of the south slope of Cells 4A and 4B and along the east of Cell 4A.
Apron B should have a median angular rock size of 10.6 inches, with a minimum width of 13.2
feet and a minimum thickness of 2.7 feet. Rock Apron C should be placed on the toes of the
remaining slope (Cell 1 disposal area side slope). Apron C should have a median rock size of
9.0 inches, a minimum width of 11.3 feet, and a minimum thickness of 2.3 feet.

Filter Requirements. NUREG-1623 (Johnson, 2002), as detailed in section G.6, was used to
determine if a bedding layer was required for the rock aprons. The results are presented in
Table G.7 below.

Based on the results in Table G.7, it is not required to place a bedding layer between the soil
and rock protection for the rock aprons.

G.8 DISCHARGE CHANNEL AND SEDIMENTATION BASIN
The PMP event described in Section G.3 was used to determine the peak discharge to the
channel to be located at the west end of the sedimentation basin. The peak discharge
calculations were made using the Rational Method and the time of concentration was calculated
for the longest flow path (see Figure G.1) across the mill site and sedimentation basin using the
procedures described in section G.4. A runoff coefficient of 1.0 was used to represent PMP
conditions (DOE, 1989). These characteristics represent high runoff quantities and peak flow
velocities.

The PMP peak discharge calculated across the mill site and sedimentation basin is presented in
Table G.8. This discharge represents the peak flow into the channel. Further details of the
calculations can be found in Attachment G.1

The peak discharge value in Table G.8 above, was used to evaluate the peak flow velocities
through the discharge channel excavated into bedrock. The channel dimensions are shown on
Drawing REC-3 and include a 150-foot bottom width and 3:1 (H:V) side slopes. The Manning’s
n-value was estimated and adjusted based on the anticipated type of bedrock and the
presumed roughness, along the channel, after excavation. Table G.9 includes peak flow
velocities for Manning’s n-values of 0.02 and 0.03.

Based on the available bedrock information near the channel location, the rock is expected to
consist of a fine to medium-grained sandstone with varying degrees of cementation and
weathering, or a claystone (Dames and Moore, 1978). The shear wave velocities from seismic
refraction surveys indicate the bedrock will range from rippable to hard rock, requiring blasting
(D’Appolonia, 1979). Because of this variability, an initial Manning’s n-value of 0.015 was
selected, for a channel in rock and then modifications of 0.005 and 0.015 were added for
increasing irregularities in the final excavated rock surface. (USBR, 1987). Maximum suggested

permissible peak channel velocities are 10 feet per second for channels excavated in “poor
rock” (USACE, 1994).

PROBABLE MAXIMUM PRECIPITATION (PMP) EVENT COMPUTATION
WHITE MESA MILL – CELL 4B
BLANDING, UTAH
OBJECTIVE
The purpose of this calculation is to evaluate the local-storm Probable Maximum
Precipitation (PMP) event for the White Mesa Mill Facility site located in Blanding,
Utah. This calculation demonstrates that the probable maximum precipitation (PMP)
event that the site will experience is 10 inches (0.83 ft) in 6 hours.
PMP COMPUTATION PROCEDURE
The Probable Maximum Precipitation (PMP) for the site was evaluated using
“Hydrometeorological Report No. 49: Probable Maximum Precipitation Estimates,
Colorado River and Great Basin Drainages” (Hansen, et. al., 1984). The use of this
method is cited in a hydrology report that was prepared as part of an agreement between
UMETCO and the Nuclear Regulatory Commission (NRC) during the permitting of
Cell 4A (UMETCO, 1990).
PROBABLE MAXIMUM PRECIPITATION EVENT CALCULATIONS
Step 1: Calculate the Average 1-hr 1-mi2 PMP for drainage using Figure 4.5

The average 1-hr 1-mi2 PMP is 8.6-in (Attachment A, 1/7)

Step 2a: Reduce the 1-hr 1-mi2 PMP event for elevation

If the lowest elevation within the drainage is above 5,000 feet (ft) above Mean Seal
Level (MSL), decrease the PMP value from Step 1 by 5% for each 1,000 ft or
proportionate fraction thereof above 5,000 ft to obtain the elevation adjusted drainage
average 1-hr 1-mi2 PMP.

The elevation of Cell 4B is 5,598 ft above MSL, which is conservatively the lowest
elevation for the completed cells 2 through 4B; therefore, it is required to interpolate

ft 598
%

%5 =; x = 3% reduction

100 % - 3 % = 97 %

Therefore, reduce the value obtained in Step 1 by 97%.

Step 2b: Multiply the number calculated in Step 1 by the number calculated in Step 2a.

8.6 inches x 0.97 = 8.3 inches

Step 3: Determine the average 6/1-hr ratio for drainage using Figure 4.7

The average 6/1-hr ratio for drainage is approximately 1.2. (Attachment A, 2/7)

Step 4: Calculate the durational variation for 6/1-hr ratio of Step 3 using Table 4.4

The durational value is determined using Table 4.4 is as follows: (Attachment A, 3/7)

Duration (hr)
¼ ½ ¾ 1 2 3 4 5 6
74 89 95 100 110 115 118 119 120 %

Step 5: Multiply step 2b by Step 4 to calculate the 1-mi2 PMP for indicated durations

For example, for the ¼ hour duration: 8.3 x 0.74 = 6.1

The following numbers are calculated as follows:

Duration (hr)

6.1 7.4 7.9 8.3 9.1 9.5 9.8 9.9 10.0 in.

Step 6: Determine the areal reduction using Figure 4.9 for the site:

First, determine the total watershed contributing to Cell 4B, including Cell 4B. The
watershed areas of the upstream Cells 2, 3, and 4A are 87 acres (ac), 83 ac, and 40 ac,
respectively and the proposed Cell 4B is 42 ac. Areas outside of these cells do not drain
to Cell 4B and are therefore not part of the watershed area.

Total acreage is 87 ac + 83 ac + 42 ac + 42 ac = 254 acres.

Using Figure 4.9, the depth ratio of ≤1 mi2 is 100 percent for each of the durations
(Attachment A, 4/7).

Step 7: Multiply the duration values in Step 5 by the areal reduction in Step 6 to
calculate the areal reduced PMP.

This step is neglected because the depth ratio is 100 percent; therefore, the values
obtained in Step 5 are not reduced.

Step 8: Calculate the incremental PMP using successive subtraction of the values in
Step 7 for the hourly durations (1 hr through 6 hr) and 15-minute incremental durations
(1/4 hr through 1 hr).

The incremental PMP is calculated in two separate steps; the incremental PMP is
calculated on the first line for the hourly increments (hours 1 through 6) and then
calculated on the second line for the 15-minute increments during the first hour of the
storm. To determine the incremental PMP, the following formula is used:
ttttotPMPPMPPMP−=++11 , where t = time
In this example, the PMP between the first interval and second interval is determined by
subtracting the PMP for interval 1 from the PMP for the second interval, as calculated
in Step 5. The following equation illustrates the calculation of the incremental PMP
between hours 0 and 1:

=−01PMPPMP 8.3 in – 0 in. = 8.3 in.
The next equation illustrates the calculation of the incremental PMP between hours 1
and 2:

=−12PMPPMP 9.1 in – 8.3 in. = 0.8 in.

This calculation is continued until the following table is completed as shown for each
PMP interval.

Duration (hr)
¼ ½ ¾ 1 2 3 4 5 6
8.3 0.8 0.4 0.2 0.1 0.1 in.
6.1 1.2 0.5 0.4 in.

Step 9: Order the incremental PMP in a sequence dictated by hourly and 15-minute
increments using Table 4.7 (Attachment 5/7) and Table 4.8 (Attachment 6/7),
respectively.

The incremental PMP calculated in Step 8 must now be arranged in a specific order to
model the runoff generated by the storm event. This order is dictated by Table 4.7 for
the hourly PMP intervals and Table 4.8 for the 15-minute PMP intervals.

The final arrangement of the numbers determined in Step 8 is as follows:

Hourly increments: 0.1 0.4 8.3 0.8 0.2 0.1 in.
15-minute increments: 6.1 1.2 0.5 0.4 in.

The storm’s 6 hour PMP runoff event is calculated by summing the incremental PMP
for each hour of the storm.
0.1 in. + 0.4 in. + 8.3 in. + 0.8 in. + 0.2 in. + 0.1 in. = 9.9 inches (10 inches).

This step is repeated to calculate the runoff generated during the first hour of the storm.
6.1 in. + 1.3 in. + 0.5 in. + 0.4 in. = 8.3 inches

Because 9.9 > 8.3, the runoff generated from the 6 hour storm (9.9 inches) is used.
CONCLUSIONS AND RECOMMENDATIONS
Our calculations are summarized in a worksheet modeled after Table 6.3A in the
Hydrometerological Report No. 49 and is provided as Attachment A, 7/7. Our analysis
determined the Probable Maximum Precipitation (PMP) event generates 10 inches (0.83
ft) over 6 hours.

D.1 INTRODUCTION
This appendix provides an evaluation of vegetation that would be used as an integral part of an
evapotranspiration (ET) cover proposed for reclamation of tailings cells at the White Mesa Mill
(Mill) site. A critical component of an ET cover is the plant community that will be established on
the cover and will function over the long term to provide protection from wind and water erosion
and assist in removing water through the process of transpiration. In this appendix, issues related
to the short-term establishment and long-term sustainability of vegetation proposed as part of the
ET cover are addressed. These issues include: plant species selection, ecological characteristics
of species (i.e., longevity, sustainability, compatibility, competition, rooting depth and root
distribution), characteristics of the established plant community (i.e., percent plant cover and leaf
area index [LAI]), and soil requirements for sustained plant growth. Information is also presented
on weed control, vegetation performance goals and criteria, and post-closure vegetation
monitoring. In addition, biointrusion from both plants and animals is addressed using information
from an on-site survey conducted in June 2012 and literature applicable to site conditions. Finally
there is discussion on climate change projections for the performance period and possible
changes that may occur with plant community composition over time.
D.2 PROPOSED SPECIES FOR ET COVER RECLAMATION
The following 15 species (11 grasses, 2 forbs, and 2 shrubs) are proposed for the ET cover
system at the Mill site. These species were selected for their adaptability to site conditions,
compatibility, and long-term sustainability. Species were also selected based on the assumption
that institutional controls will exclude grazing by domestic livestock. The proposed species are:
 Western wheatgrass, variety Arriba (Pascopyrum smithii)
 Bluebunch wheatgrass, variety Goldar (Pseudoroegneria spicata)
 Slender wheatgrass, variety San Luis (Elymus trachycaulus)
 Streambank wheatgrass, variety Sodar (Elymus lanceolatus ssp. psammophilus)
 Pubescent wheatgrass, variety Luna (Thinopyrum intermedium ssp. barbulatum)
 Indian ricegrass, variety Paloma (Achnatherum hymenoides)
 Sandberg bluegrass, variety Canbar (Poa secunda)
 Sheep fescue, variety Covar (Festuca ovina)
 Squirreltail, variety Toe Jam Creek (Elymus elymoides)
 Blue grama, variety Hachita (Bouteloua gracilis)
 Galleta, variety Viva (Hilaria jamesii)
 Common yarrow, no variety (Achillea millefolium)
 White sage, variety Summit (Artemisia ludoviciana)
 Fourwing saltbush, variety Wytana (Atriplex canescens)
 Rubber rabbitbrush, no variety (Ericameria nauseosus).
These species are described in more detail later in this appendix.

D.3 PROPOSED SEEDING RATES
Given a mixture of the species listed above, Table D.1 presents broadcast seeding rates for each
species. Seeding rates were developed based on the objective of establishing a permanent cover
of grasses, forbs, and shrubs in a mixture that would promote compatibility among species and
minimize competitive exclusion or loss of species over time. The proposed seeding rate is based
on number of seeds/ft2 and then converted to pounds of pure live seed per acre (lbs PLS/acre),
with further discussion presented below.
The number of seeds placed in a unit area of soil is called the seeding rate. The total seeding
rate is the sum of the individual species seeding rates. Seeding rates are normally expressed as
the number of seeds per square foot or pounds per acre. Many different seeding rates for the
same species can be found in the literature. The primary reason for these differences is that
some rates are for monocultures and other rates are for diverse mixtures. In addition, seeding
rates vary depending on the method of seeding and site conditions related to edpaphic factors,
topography and climate.
Seeding rates are developed on the basis of number of seeds per unit area (e.g. number of seeds
per square foot). Once this number is determined, then it can be converted to weight per unit
area (e.g. pounds per acre). Since each species produces seed that weighs a different amount,
the development of seeding rates based purely on weight per unit area will produce erroneous
rates that will tend to over emphasize small seeded species and under-emphasize large seeded
species. For example, blue grama has approximately 700,000 seeds per pound, while Indian
ricegrass has approximately 175,000 seeds per pound. If seeding rates were calculated simply
on the basis of weight per unit area, without recognizing the fact that a pound of blue grama seed
has four times the number of seeds per pound as Indian ricegrass, it would be very easy to over
plant blue grama and under plant Indian ricegrass.

†Seeding rate is for broadcast seed and presented as pounds of pure live seed per acre (lbs PLS/acre).
‡Introduced refers to species that have been ‘introduced’ from another geographic region, typically
outside of North America. Also referred to as ‘exotic’ species. *VNS=Variety Not Specified but seed
source would be designated from sites similar to the Mill site.

Seeding rate may be calculated from an expected field emergence for each species and the
desired number of plants per unit area. For purposes of calculation, field emergence for small
seeded grasses and forbs is assumed to be around 50 percent if germination is greater than 80
percent. Field emergence is assumed to be around 30 percent if germination is between 60 and
80 percent. The Natural Resource Conservation Service recommends a seeding rate of 20 to 30
pure live seeds per square foot as a minimum number of seeds when drill seeding single species
in areas with an annual precipitation between 6 and 18 inches. Twenty pure live seeds per square
foot, with an expected field emergence of 50 percent should produce an adequate number of
plants on the seeded area to control erosion and suppress annual invasion. This seeding rate is
primarily for favorable growing conditions, soils that are not extreme in texture, gentle slopes,
north or east facing aspect, good moisture, adequate soil nutrients and single species vs. multiple
species in a mixture. When conditions are less favorable when the seed is broadcast, or when
multiple species are in a mixture the seeding rates are increased.
A Quality Assurance/Quality Control Plan for application rates and procedures for confirming that
specified application rates are achieved is as follows. The first step begins with a seed order.
Seed would be purchased as pounds of pure live seed. Each State has a seed certifying agency
and certification programs may be adopted by seed growers. Certification of a container of seed
assures the customer that the seed is correctly identified and genetically pure. The State agency
responsible for seed certification sets minimum standards for mechanical purity and germination
for each species of seed. When certified, a container of seed must be labeled as to origin,
germination percentage, date of the germination test, percentage of pure seed (by weight), other
crop and weed seeds, and inert material. The certification is the consumer’s best guarantee that
the seed being purchased meets minimum standards and the quality specified.
Once the seed is obtained, seed labels would be checked to determine the percent PLS and the
date that the seed was tested for percent purity and percent germination. If the test date is greater
than 6 months old, the seed would be tested again before being accepted. Seed will be applied
using a broadcasting method. This procedure would use a centrifugal type broadcaster (or similar
implement)), also called an end-gate seeder. These broadcasters operate with an electric motor
and are usually mounted on the back of a small tractor and generally have an effective spreading
width of about 20 feet or more. Prior to seeding, a known area will be covered with a tarp and
seed will be distributed using the broadcaster and simulating conditions that would exist under
actual seeding conditions. Seed will then be collected and weighed to determine actual seeding
rate in terms of pounds per acre. This process will be repeated until the specified seeding rate is

obtained. During the seeding process, the seeding rate will be verified at least once by comparing
pounds of seed applied to the size of the area seeded. In addition, seed will be applied in two
separate passes. One-half of the seed will be spread in one direction and the other half of seed
will be spread in a perpendicular direction. This will ensure that seed distribution across the site
is highly uniform and also provide the opportunity to adjust the seeding rate if the specified rate
is not being achieved.
D.4 ECOLOGICAL CHARACTERISTICS OF PROPOSED SPECIES AND ESTABLISHED
PLANT COMMUNITY
D.4.1 Ecological Characteristics of Plant Species of Tailings Cover System
Important ecological characteristics for each species proposed for reclamation are provided in the
paragraphs that follow. Species information was obtained from a number of references that are
cited below. The proposed species are adapted to the elevation (5,600 feet), precipitation (13
inches per year on average), and soil textural ranges (loam to sandy clay) that are well within the
environmental conditions of the Mill site. Table D.2 presents a summary of the ecological
characteristics discussed in the following paragraphs.
Western wheatgrass, variety Arriba (Pascopyrum smithii) – Western wheatgrass is a native,
rhizomatous, long-lived perennial cool season grass. It grows well in a 10- to 14-inch mean
annual precipitation zone and is adapted to a wide range of soil textural classes at elevation
ranges up to 9,000 feet. Western wheatgrass has been an important species for restoring mining
related disturbances, for erosion control and for critical area stabilization in semi-arid regions
because of its ease of establishment and ability to grow successfully in pure or mixed stands of
both warm and cool season species. Western wheatgrass is fire tolerant and regenerates readily
following burning. The variety of Arriba is known for rapidly establishing seedlings and high seed
production. The combination of its ability to spread vegetatively and reproduce by seed ensures
long-term sustainability of this species.
Bluebunch wheatgrass, variety Goldar (Pseudoroegneria spicata) – Bluebunch wheatgrass
is a native, cool season perennial bunch grass. Bluebunch wheatgrass grows on soils that vary
in texture, depth and parent material. It is one of the most important and productive grasses found
in sagebrush communities in the intermountain west. Bluebunch wheatgrass is fire tolerant and
regenerates vegetatively following burning. This species is well adapted to a 12- to 14-inch mean
annual precipitation range and is considered to be highly drought resistant. Bluebunch
wheatgrass performs well in mixtures with other species and grows at elevations up to 10,000
feet.
Slender wheatgrass, variety San Luis (Elymus trachycaulus) – Slender wheatgrass is a
native, cool season, perennial bunch grass that occasional produces rhizomes. It is a short-lived
species (5 to 10 years) but it reseeds and spreads well by natural seeding, exceeding most other
wheatgrasses in this characteristic. Slender wheatgrass can serve as an important pioneer
species; its seedlings are vigorous and capable of establishing on harsh sites. In addition, it is
able to establish and compete with weedy species. Slender wheatgrass is commonly seeded in
mixtures with other grasses and forbs to restore disturbances and rehabilitate native communities.
It is adapted to a wide variety of sites and is moderately drought tolerant. It performs best at sites
with an annual precipitation of 15 inches or more, but can grow on sites with precipitation levels
as low as 13 inches.

D-6 August 2015
Streambank wheatgrass, variety Sodar (Elymus lanceolatus ssp. psammophilus) –
Streambank wheatgrass is considered to be part of the thickspike wheatgrass (Elymus
lanceolatus ssp. lanceolatus) taxa. Variety Sodar is a native, perennial sod grass that is highly
rhizomatous and adapted to the western intermountain area. It is highly drought tolerant and
performs well in mean annual precipitation ranges between 11 and 18 inches. It grows on a wide
range of soil textures, from sandy to clayey. Streambank wheatgrass is commonly used in mine
land reclamation and is best known for its ability to control erosion and compete with annual
weeds. Its highly rhizomatous nature ensures long-term sustainability of this species.
Pubescent wheatgrass, variety Luna (Thinopyrum intermedium ssp. barbulatum) –
Pubescent wheatgrass is a long-lived sod forming perennial introduced from Eurasia. It is highly
drought tolerant and grows where the mean annual precipitation is 12 inches or more. It is
adapted to a wide range of soil textures, from sand to clay. Pubescent wheatgrass is a highly
persistent species, should be seeded at low densities to avoid competition with native species.
Indian ricegrass, variety Paloma (Achnatherum hymenoides) – Indian ricegrass is a native,
cool season, perennial bunchgrass with a highly fibrous root system. Indian ricegrass is one of
the most common grasses on semi-arid lands in the west and is one of the most drought tolerant
species used in mine land reclamation. It generally occurs on sandy soils, but is found on soils
ranging from sandy to heavy clays. It grows from 2,000 to 10,000 feet in areas where the mean
annual precipitation is 6 to 16 inches. Indian ricegrass is slow to establish, but highly persistent
once it becomes established.
Sandberg bluegrass, variety Canbar (Poa secunda) – Sandberg bluegrass is a native, cool
season perennial bunchgrass that is adapted to all soil textures and is highly resistant to fire
damage. Sandberg bluegrass is one of the more common early-season bunchgrasses in the
Intermountain area. It grows at elevations from 1,000 to 12,000 feet and can be successfully
established in areas with a mean annual precipitation of 12 inches or more. Established plants
are not overly competitive, and therefore highly compatible with other native species.
Sheep fescue, variety Covar (Festuca ovina) – Sheep fescue is a short, mat-forming introduced
perennial that grows well on infertile soils in areas with a mean annual precipitation of 10 to 14
inches. It is long-lived and highly drought tolerant. Sheep fescue is a cool season species that
greens up early in the spring. The proposed variety, Covar, was introduced from Turkey and is
commonly used in mine land reclamation for long-term stabilization and erosion control. This
variety was selected because plants are persistent, winter hardy, and drought tolerant.
Squirreltail, variety Toe Jam Creek (Elymus elymoides) – Squirreltail is a short-lived perennial
that is selected for its ability to establish quickly and to effectively compete with undesirable annual
grasses. It grows along an elevation range from 2,000 to 11,000 feet and on all soil textures in
mean annual precipitations zones of 8 to 15 inches. Squirreltail is fairly tolerant of fire because
of its small size.
Blue grama, variety Hachita (Bouteloua gracilis) – Blue grama is a low-growing perennial
warm season bunchgrass. Blue grama produces an efficient, widely spreading root system that
is mostly concentrated near the soil surface. Blue grama is adapted to a variety of soil types, but
does best on well-drained soils and once established, is highly drought tolerant. This species is
commonly found with cool-season species and is highly compatible with other native perennials.

Energy Fuels Resources (USA) Inc. MWH Americas, Inc.
D-7 August 2015
Galleta, variety Viva (Hilaria jamesii) – Galleta is a strongly rhizomatous perennial warm season
grass with a dense, fibrous root system. Galleta grows on sits receiving 6 to 18 inches of annual
precipitation with soils ranging from coarse to fine. Plants have a low requirement for soil fertility
and are drought and fire tolerant.
Common yarrow (Achillea millefolium, var. occidentalis) – Yarrow is a common native forb
species that is rhizomatous and found growing from valley bottoms to timberline. It is commonly
used in mine land reclamation, establishes easily from seed and is highly persistent. It grows on
a variety of soil textures and found in a mean annual precipitation range between 13 and 18
inches. If seed is not available for Achillea millefolium var. occidentalis, then the introduced
Achillea millefolium would be used, which has the same growth characteristics as the native form.
White sage, variety Summit (Artemisia ludoviciana) – White sage is considered to be a
pioneer rhizomatous forb species that establishes quickly on disturbed sites and is highly
compatible with perennial grasses. It does best on well-drained soils, but can be found growing
on a wide range of soil textures. It is adapted to sites above 5,000 feet in elevation and to sites
with a mean annual precipitation above 12 inches.
Fourwing saltbush, variety Wytana (Atriplex canescens) – Fourwing saltbush can be
deciduous or evergreen, depending on climate. Its much-branched stems are stout and mature
plants range from 1 to 8 feet in height, depending on ecotype, the soil, and climate. Fourwing
saltbush is one of the most widely distributed and important native shrubs on rangelands in the
western United States. Fourwing saltbush is highly palatable browse and is utilized primarily in
the winter at which time it is high in carotene and digestible protein. Fourwing saltbush provides
excellent season long browse for deer. It is a good browse plant for antelope and elk in fall and
winter. It is also a food source and excellent cover for upland birds. Fourwing saltbush has
excellent drought tolerance. Fourwing saltbush is adapted to most soils but is best suited to loamy
to sandy to gravely soils. It is not especially tolerant of fire, but may re-sprout to some degree if
fire intensity is not too severe. Fourwing saltbush occurs most commonly in salt-desert scrub
communities in the desert areas of western North America in areas that receive 8 to 14 inches of
annual precipitation. It can be found from sea level in Texas to over 8,000 feet in Wyoming.

Rubber rabbitbrush (Ericameria nauseosus) – Rubber rabbitbrush is a native, perennial,
warm-season shrub that grows to 1 to 8 feet tall. Rubber rabbitbrush is an important browse
species for wildlife during the winter months. Rubber rabbitbrush occurs as a dominant to minor
component in many plant communities, ranging from arid rangelands to montane openings. It
thrives in poor conditions, and can tolerate coarse, alkaline soils. Dense stands are often found
on degraded rangelands, along roadsides, and in abandoned agricultural fields. The species is
useful in soil stabilization and restoration of disturbed sites. The root system establishes quickly
and plants produce large quantities of leaf litter. Rubber rabbitbrush is adapted to cold, dry
environments receiving 7 to 18 inches of annual precipitation at elevations ranging from 450 to
8,000 feet. Depending on the ecotype, rubber rabbitbrush can be found on loamy, sandy, gravelly
or heavy clay soils that are slightly acidic, slight to strongly basic, or saline.

D.4.2 Longevity and Sustainability
All of the species proposed for reclamation of the tailings cells are long-lived, except for slender
wheatgrass (Elymus trachycaulus) and squirreltail (Elymus elymoides). Slender wheatgrass is a
perennial bunchgrass that is short-lived (5 to 10 years) but has the ability to reseed and spread
vegetatively with rhizomes. Squirreltail is also a short-lived perennial but has the ability to
establish quickly and is highly effective in competing with undesirable annual grasses. Both of
these species are included in the proposed seed mixture because of their ability to provide quick
cover for erosion protection and to effectively compete with annual and biennial species that
cannot be relied upon to provide consistent and sustainable plant cover. The use of these species
will facilitate the establishment of the remaining long-lived perennials that have been documented
to be highly adapted to the elevation, climate, and soil conditions found at the Mill site (Monsen
et al., 2004; Alderson and Sharp, 1994; Wasser, 1982; Thornburg, 1982).
The perennial grasses, forbs, and shrubs in the proposed seed mixture include species that
develop individual plants that are long lived (30 years or more) and are able to reproduce either
by seed or vegetative plant parts like rhizomes and tillers. The use of these species in reclamation
of the tailings cells will ensure a permanent or sustainable plant cover because of the highly
adapted nature of these species to site conditions, their tolerance to environmental stresses such
as drought, fire, and herbivory, and their ability to effectively reproduce over time.
The use of a mixture of species for the ET cover also contributes to longevity and sustainability.
The establishment of a diverse community has many advantages over a monoculture for
sustained plant growth. The use of a variety of species ensures that diverse microsites that may
exist over a seeded site are properly matched with species that are adapted to those specific
environmental conditions. In addition, a mixture of species reverses the loss of plant diversity
and enhances natural recovery processes following impacts from insects, disease organisms,
and adverse or changes in climatic conditions. Finally, mixtures provide improved ground cover
and surface stability, along with reducing weed invasion by fully utilizing plant resources such as
water, nutrients, sunlight and space. Weeds in this context are typically annual or biennial plants
considered to be undesirable, especially growing where they are not wanted.
D.4.3 Compatibility
Reclamation research and its application have been ongoing in the U.S. since the early 1900s.
First with the reseeding of millions of acres following the dust bowl of the 1930s. Then,
improvements of large tracts of arid and semi-arid rangelands between the 1960s and 1980s
following more than a half a century of rangeland exploitation through overgrazing. In 1985 the
U.S. Department of Agriculture Conservation Reserve Program was implemented which resulted
in the conversion of more than 40 million acres of marginal farm land to permanent grasslands
through an extensive seeding program. Finally, there have been tens of thousands of acres of
mined lands reclaimed across the U.S. with the implementation of federal and state rules and
regulations governing mine land reclamation. Over this time period, there have been thousands
of reclamation publications in the form of books, scientific journal articles, symposium
proceedings, and government publications. Many publications have reported on the performance
of individual species and mixtures of species under semi-arid conditions similar to southeastern
Utah (e.g., Plummer et al., 1968; Monsen et al., 2004). All of this work has led to a knowledge
base about species compatibility. Species that are seeded together in mixtures must be
compatible as young, developing plants or certain individuals will succeed and others will fail. The
species proposed for the ET cover at the Mill site are all compatible with each other and seeding
rates will be used to prevent overseeding species that may be aggressive [e.g., pubescent
wheatgrass (Thinopyrum intermedium)] and could potentially dominate the site (Monsen et al.,

Updated Tailings Cover Design Report

Energy Fuels Resources (USA) Inc. MWH Americas, Inc.
D-9 August 2015
2004). These species are commonly seeded together and many studies have shown excellent
interspecies compatibility (e.g., DePuit et al., 1978; DePuit, 1982; Redente et al., 1984; Sydnor
and Redente, 2000; Newman and Redente, 2001). Finally, to increase compatibility and to reduce
competition among seeded species, sites would be broadcast seeded as opposed to drill seeded.
According to Monsen et al. (2004), drill seeding causes species in a mixture to be placed in
potentially competitive situations, while broadcasted seeds are not placed in as close contact with
each other as with drilling and therefore are less likely to be negatively impacted from competition.
D.4.4 Competition
There are two ways to view competition. In the context of establishing an ET cover on the tailings
cells, the use of seeded species to compete with weeds is a desirable attribute. However,
competition among seeded species with the potential loss of any of these species is undesirable.
Therefore, as stated earlier, the proposed seed mixtures is comprised of species that can coexist
and also fully utilize plant resources to minimize weed species establishment and excluding
seeded species. The establishment of weeds, especially invasives (i.e., non-native species
whose introduction causes economic and environmental harm) is unacceptable because of the
potential loss of seeded perennial species and the subsequent reduction in species diversity,
plant cover, and overall sustainability. Once established, the proposed seed mixture will produce
a grass-forb-shrub community of highly adapted and productive species that will effectively
compete with undesirable species.
D.4.5 Plant Cover
Monitoring of an alternative cover at the Monticello, Utah, Uranium Mill Tailings Disposal Site
showed that the plant cover performed well over a seven year period. Plant cover ranged from
5.5 percent during the first growing season to nearly 46 percent in the seventh growing season
(Waugh et al., 2008). Using results from the 2007 vegetation monitoring report (DOE, 2008) the
following contributions to relative cover were reported showing that 6 of the 16 species seeded
provided 70 percent or more of the cover when cover differences between reclamation zones is
averaged: big sagebrush—5 percent to 10 percent; rubber rabbitbrush—5.3 percent to 17
percent; western wheatgrass—38.6 percent; cicer milkvetch—11 percent; thickspike
wheatgrass—7.2 percent; and globemallow—0.1 to 0.2 percent.
Approximately 40 percent of the species proposed for the Mill site were seeded at Monticello and
of the six best-performing species, three of these species are in the White Mesa mixture (i.e.
Pascopyrum smithii, Elymus lanceolatus, and Ericameria nauseosus ). Highly competitive
species used at Monticello that are not proposed for White Mesa include three introduced species
(i.e. smooth brome, crested wheatgrass, and alfalfa) that were not considered acceptable for the
Mill site. Based on these results and the similarity in environmental conditions between Monticello
and White Mesa, a plant cover estimate of 40 percent was determined to be a reasonable estimate
for a long-term average, while a percent plant cover of 30 percent was assigned as a reduced
performance scenario. The percent vegetative cover at White Mesa is expected to be slightly
less than what would be found at Monticello because the average annual precipitation at White
Mesa is approximately 13 inches compared to 15 inches at Monticello and the average annual
maximum/minimum air temperatures are 64/37oF for White Mesa and 59/33oF for Monticello. The
slightly greater precipitation and lower temperatures at Monticello are due to its slightly higher
elevation of 7,000 feet compared to 5,600 feet at White Mesa.
A map of current vegetation at the Mill site does not exist. The most recent mapping of vegetation
at the Mill site was conducted by Dames and Moore in 1977 (Dames and Moore 1978) as part of
the Environmental Report for the White Mesa Uranium Project. In 1977, the major mapping units

for the project site were: big sagebrush (232 acres), controlled big sagebrush (567 acres), and
reseeded grassland (369 acres). In June 2012 the area surrounding the Mill site was surveyed
for plant community composition and cover in response to Interrogatory 11/1: Vegetation and
Biointrusion Evaluation and Revegetation Plan of DRC (2012). There are two principal plant
community types in the vicinity of the Mill site. These plant communities are Big Sagebrush
shrubland and Juniper woodland. The Dames and Moore Environmental Report (1978) classified
the Juniper woodland as a Pinyon-Juniper community type, but the primary tree species is Utah
juniper (Juniperus osteosperma) and the presence of pinyon pine (Pinus edulis) is so infrequent
that the community may be more appropriately classified as a Juniper woodland. In addition to
these two principal plant community types, there are a number of disturbed areas that are in
different stages of successional development and reflect past disturbances such as sagebrush
removal (chaining and plowing) and seeding and intense grazing as evidenced by a complete
lack of any understory species in some areas. The vegetation survey conducted in 2012 provides
information of species that exist on the Mill site and their relative importance in terms of plant
cover. All areas surveyed in 2012 show that big sagebrush (Artemisia tridentata) is the dominant
species and subdominants are either broom snakeweed (Gutierrezia sarothroae) or galleta
(Hilaria jamesii). If the area were re-mapped, most of the site would map as Big Sagebrush
association. It appears that areas that were reseeded to crested wheatgrass and areas where
controlled measures were applied to remove big sagebrush have returned to big sagebrush
following seeding and/or control measures implemented sometime prior to 1978.
The Big Sagebrush shrubland is dominated by big sagebrush (Artemisia tridentata) with
interspersed shrubs of broom snakeweed (Gutierrezia sarothroae) pale desert-thorn (Lycium
pallidum var. pallidum), and rubber rabbitbrush (Ericameria nauseosa). The understory is mostly
grasses with an infrequent occurrence of forbs. The grasses include galleta (Hilaria jamesii),
squirreltail (Elymus elymoides), Indian ricegrass (Achnatherum hymenoides), and cheatgrass
(Bromus tectorum). Forb species include scarlet globemallow (Sphaeralcea coccinea), lesser
rushy milkvetch (Astragalus convallarius), and Russian thistle (Salsola kali).
The Juniper woodland occurs on shallow soils along the canyon rim to the east and west of the
site. It is highly unlikely that this community type would expand its range into the deep, very fine
sandy loam soil that occurs on the Mill site, which is the primary soil type supporting the Big
Sagebrush shrubland. The vegetation sampling that was conducted in 2012 focused on the Big
Sagebrush community and did not include the Juniper woodland because of the unlikely
probability that this community type would ever establish on the Mill site or tailings cell cover
system. A reconnaissance level survey was conducted in the Juniper community to observe both
plant and animal species that occupy these areas.
D.4.6 2012 Plant Survey
The big sagebrush community type within the White Mesa Control Area to the north, south, and
west of the restricted area of the mill and tailings facilities was surveyed using randomly placed
transects and estimating cover by species using a point intercept sampling method (see Figure
D.1). Along each 100 m long transect, live plant cover by species was determined by lowering a
pin at 1 meter intervals and recording the plant species or ground cover (litter and bareground)
that intersected the point. A total of 10 transects were sampled in each of the areas to the north,
south and west of the mill and tailings cells. Table D.3 presents a summary of the vegetation
survey conducted in the areas surrounding the mill and tailings cells. Tables D.4 through D.33
present plant cover data by transect for each of the three areas sampled in 2012.

Results from the 2012 sampling of the Big Sagebrush community surrounding the Mill site showed
a mean live plant cover of 37.8 percent after averaging live plant cover estimated in areas north,
south and west of the Mill site (Table D.3). This plant cover included an average of 23.1 percent

cover for shrubs, 13.7 percent cover for grasses, and 1.0 percent cover for forbs. In addition, the
average percent litter was 13.1 percent and bareground averaged 49.1 percent. These cover
estimates are somewhat greater than the cover values reported in Dames and Moore
Environmental Report (1978). In the Environmental Report, the average live plant cover in the
Big Sagebrush community was 33.3 percent. This cover included an average of 19.4 percent for
shrubs and 13.8 percent for grasses. Litter was estimated at 16.9 percent and bareground was
49.9 percent. Annual precipitation in 1977 was 23.6 cm compared to a long-term average of 29.7
cm (Dames and Moore 1978). In addition, monthly precipitation during the period May-September
1978 totaled 3.8 cm compared to a long-term average of 12.5 cm for the same period.
Considering the fact that the areas sampled are currently grazed, it is highly likely that a cover of
40 percent can be achieved and maintained on the tailings cell cover system for conditions that
exclude grazing by livestock. The formation of desert pavement and potential impact on plant
cover has been raised as an issue for discussion. Desert pavements are armored surfaces
composed of angular or rounded rock fragments, usually 2 to 3 cm thick, set on or in a matrix of
finer material (Cooke and Warren, 1973). These surfaces form on arid soils through deflation of
fine material by wind or water erosion due to a lack of protection by surface vegetation (Cooke
and Warren, 1973). Desert pavements are not common in semi-arid regions and do not occur
where either wind or water erosion are controlled by plant cover (Hendricks, 1991), as would be
the case for the White Mesa cover system. In addition, there is no evidence of desert pavement
formation either on the Mill site or areas surrounding the site (which was confirmed during the
2012 plant survey). Even with the use of a topsoil layer amended with gravel, there is no
supporting evidence to indicate a potential for desert pavement formation or an associated
decrease in plant cover over the long term.

D.4.7 Leaf Area Index
Monthly leaf area index (LAI) values were estimated for the proposed ET cover at the Mill site.
Three primary publications were used to estimate monthly LAI for the ET cover, including:
Groeneveld (1997), Scurlock et al. (2001), and Fang et al. (2008). Table D.34 presents a
compilation of LAI values based on North American data sets that were focused on semi-arid
herbaceous plant communities. Scurlock et al. (2001) presented mean LAI values for 15
biomes/land cover classes that included desert, grassland, and shrubland. Leaf Area Index data
was a compilation of data from the literature and represented various data collection methods.
Mean LAI values reported were 1.3 (S.D. 0.85) for desert, 2.6 (S.D. 3.0) for grassland, and 2.1
(S.D. 1.6) for shrubland. Fang et al. (2008) presented LAI data for various biomes using MODIS
(Moderate Resolution Imaging Spectroradiometer). These authors reported monthly LAIs for
grasslands and shrublands with peak values for shrubland reported at 1.5 and 1.0 for grasslands.
Finally, Groeneveld (1997) conducted field measurements of LAI in Owens Valley, CA in 1983.
He reported LAI values for individual grass and shrub species and reported the following values
in November for big sagebrush and in July for the remaining species: big sagebrush LAI’s ranged
from 0.65 to 1.8; fourwing saltbush (Atriplex canescens) LAI’s ranged from 1.2 to 4.7; shadscale
saltbush (Atriplex confertifolia) LAI’s ranged from 1.6 to 2.6; greasewood (Sarcobatus
vermiculatus) LAI’s ranged from 1.0 to 3.3; alkali sacaton (Sporobolus airoides) LAI’s ranged from
0.38 to 4.0; and saltgrass (Distichlis spicata) LAI’s ranged from 0.67 to 3.9. All of the data
presented in these three papers was used to estimate an average monthly LAI for the revegetated
cover system assuming a well-established plant community. A maximum LAI of 2.6 was selected
for peak biomass in the month of September which matches the mean grassland LAI reported by
Scurlock al. (2001) and well below values reported by Groeneveld (1997). Leaf Area Index values
for the remaining months was then extrapolated from the peak month using monthly values
presented by Fang et al. (2008). It is important to note that the proposed species for the ET cover
include both cool- and warm-season species. This combination of species will maximize the
length of the growing season and transpiration from early spring to late fall. Cool-season species
are more productive and use more water during the cooler times of the growing season, while
warm-season species are more productive and use more water during the warmest period of the
year.

D.4.8 Project Root Biomass for Infiltration Modeling
We have chosen to use root biomass data from a seeded site in Cheyenne, Wyoming that was
seeded in the 1950s with root biomass data collected about 35 years after seeding (Redente et
al. 1989). Data were collected as g/m2 and will not be converted (Table D.35). Infiltration model
uses a normalized root density function, so root measurement units are irrelevant. The climatic
conditions between Blanding, Utah and Cheyenne, Wyoming are similar with Blanding receiving
34 cm of precipitation and Cheyenne receiving 36 cm. Potential evapotranspiration (PET) at
Blanding is 122 cm and 115 cm in Cheyenne. Finally, the precipitation to PET ratio is 0.28 for
Blanding and 0.31 for Cheyenne. Table D.35 presents both anticipated root biomass and reduced
biomass that is calculated based on a 75 percent reduction in biomass that has been reported in
long-term drought studies (Weaver and Albertson 1936).

use in infiltration modelling

†Based on an increasing percent reduction from 60% to 80% with depth, as extended drought or reduced
precipitation with potential climate change would result in less deep infiltration and therefore greater
negative effect on deeper roots compared to shallower roots. ‡Maximum rooting depth under the reduced
performance scenario would be 68 cm.

D.5 BIOINTRUSION
D.5.1 Plant Intrusion
Table D.36 presents percent of root mass by depth for grass and shrub species that exist or may
occur on the Mill site during the performance period. It is extremely important to recognize that
the rooting depths for the shrubs do not reflect the rooting depths that are expected in the cover
system but represent rooting depths reported in the literature with an effort to identify the
maximum rooting depths reported. Detailed rooting depth studies are rare and the majority of
studies do not report root mass by depth. The shrub values reported in Table D.36 represent
extrapolations from the literature using the maximum rooting depths reported and following the
general findings in the literature that the majority of root growth typically is in the upper 30 cm for
grasses and the upper 60 cm for shrubs growing in semiarid regions. The final note of importance
that relates to the cover system is that root growth is strongly influenced by the soil which the root
is growing and therefore root data from the literature must be carefully scrutinized as it is applied
to specific site conditions (Munshower 1995). The shrub root data shown in Table D.36 should
therefore not be interpreted to represent the expected rooting depths in the cover system since

rooting depth will be controlled by the highly compacted radon attenuation layer within the cover
system.
Soil texture appears to be the most important soil property determining the growth-limiting bulk
density of a soil because of the effect of texture on soil pore size and mechanical resistance. A
soil with a large amount of fine particles (silt and clay) will have smaller pore diameters and a
higher penetration resistance at a lower bulk density than a soil with a large amount of coarse
particles (sand size). Zisa et al. (1980) reported a silt loam soil had 19 percent macropore space
and a measured penetration resistance of 2.5 bars at a bulk density of 1.4 g/cm3. A coarser sandy
loam soil had 28.9 percent macropore space and a penetration resistance of 1.2 bars at the same
bulk density.
Roots grow in soil through large soil pores and by moving soil particles aside when the roots
penetrate pores that are smaller than the root tips. When a soil is compacted to a growth-limiting
level, most soil pore diameters are substantially smaller than the diameters of growing roots. In
this situation, root growth is essentially halted because the roots cannot exert enough pressure
to overcome the mechanical resistance and move soil particles. Other pertinent studies that relate
root growth and bulk density include articles by Siegel Issem et al. 2005, Mimore and Woollard
1969, and Heilman 1981.
Most, if not all, of the root growth studies cited above that relate root growth to soil compaction
and soil bulk density are field studies in native soils that have been in place for centuries or longer.
These soils have therefore gone through countless wetting and drying cycles and freeze-thaw
cycles and still maintain certain bulk densities that impede root growth.

D.5.2 Animal Intrusion
The Dames and Moore Environmental Report (1978) included animal surveys for sites
surrounding the Mill site. The Environmental Report recorded the presence or possible presence
of a number of burrowing species in the Big Sagebrush community, including burrowing owl (Bubo
virginianus), pocket mouse (Perognathus sp.), kangaroo mouse (Microdipodops sp.), vole
(Microtus sp.), desert cottontail (Sylvilagus audubonii), coyote (Canis latrans), red fox (Vulpes
vulpes), striped skunk (Mephitis mephitis), badger (Taxidea taxus), longtail weasel (Mustela
frenata), and Gunnison prairie dog (Cynomys gunnisoni). Additional burrowing animals reported
to occur in the Juniper community included pinyon mouse (Peromyscus truei) and deer mouse
(Peromyscus maniculatus). The northern pocket gopher (Thomomys talpoides) was not observed
in either community type and no mention of the species is made in the 1978 report.
D.5.3 2012 Burrowing Animal Survey
In June 2012 the area surrounding the Mill site was surveyed for burrowing animals in response
to Interrogatory 11/1. A total of 100 km of transects were walked in Big Sagebrush and Juniper
communities surrounding the Mill Site to determine either the presence of burrowing animals or
future colonization based on existing habitat characteristics (see Figure D.2).
Transects were arranged in a systematic manner (at each location in Figure D.2) with a 50 m
spacing between transects and transect lengths running between 100 and 400 m, depending
upon physiographic features on the landscape. The primary focus of the survey was on three
species that would potentially represent the deepest potential for burrows on the tailings cells
during the performance period. These species included the badger, Gunnison prairie dog, and
northern pocket gopher. Observations were made along each transect for animal sightings,
animal presence in the form of tracks, scat or active burrows, burrow densities, and habitat
characteristics.
During the animal survey one badger sighting was made and multiple active prairie dog colonies
were observed to the north of the mill complex. There appears to be suitable habitat for the
northern pocket gopher in the sagebrush communities surrounding the Mill site, but there is no
indication that a population of northern pocket gophers occurs in the vicinity of the Mill site. There
were no evidence of pocket gophers during surveys associated with the Environmental Report
(Dames and Moore, 1978) and no evidence of pocket gophers 34 years later.
An attempt was made to estimate burrow densities for badgers but it was not always possible to
confirm a badger burrow. No badger feeding areas (i.e. dug-out prey burrows) were observed
along transects that were traversed. The reported burrow density for badgers may or may not be
low, depending upon how active badgers are in the area. One of the seminal studies on badger
ecology was conducted by Messick and Hornocker (1981) in southwestern Idaho. The authors
reported badger densities of 159/50 km2. This converts to approximately three per 100 hectares.
Our survey reported the highest burrow densities at one per 80 to 100 hectares. If each burrow
represented more than one individual badger, the densities potentially would be greater.
Regardless, the reported burrow densities from the 2012 survey are believed to be a realistic
estimate of badger presence at the Mill site.

Within the prairie dog colonies that were located in the area of the Mill site, the greatest burrow
density was estimated at 148 burrows per hectare. Over the entire Mill site the prairie dog burrow
density ranges from 0 to 148 burrows per hectare. Lupis et al. (2007) reported densities of active
burrows in southeastern Utah in the range of 41 to 131/hectare or an average of 75 active burrows

per hectare. The burrow densities reported from out 2012 survey are well within the range of a
much larger study conducted by Lupis et al. (2007).

Lupis et al. (2007) provide a list of species in grasslands and shrublands in Utah considered
primary and secondary habitat for the Gunnison’s prairie dog as follows:

“Perennial and annual Grasslands; or herbaceous dry meadows, including mostly forbs
and grasses occurring at 640-2,740 m (2,200-9,000 ft) elevation. Principal perennial grass
species include: bluebunch wheatgrass, sandburg bluegrass (Poa secunda), crested
wheatgrass (Agropyron cristatum), basin wildrye (Elymus cinereus), galleta (Pleuraphis
jamesii), needlegrass (Achnatherum hymenoides), sand dropseed (Sporobolus
cryptandrus), blue grama (Bouteloua gracilis), Thurbers needlegrass (Achnatherum
thurberianum), western wheatgrass (Pascopyum smithii), squirreltail (Sitanion hystrix),
timothy (Phleum spp.), poa (Poa spp.), spike (Trisetum spicatum), Indian ricegrass
(Oryzopsis hymenoides), and some sedges (Cyperaceae spp.). Principle annual grass
species is cheatgrass (Bromus tectorum). Principal forb species include: yarrow (Achillea
millefolium), dandelion (Taraxacum officinale), Richardson's geranium (Geranium
richardsonii), penstemon (Penstemon spp.), mulesears (Wyethia amplexicaulis), golden
aster (Chrysopsis villosa), arrowleaf balsamroot (Balsamorhiza sagittata), hawkbit
(Agoseris pumila), larkspur (Delphinium spp.), and scarlet gilia (Gilia pulchella). Primary
associated shrub species include: sagebrush (Artemesia spp.), shadscale (Atriplex
confertifolia), greasewood (Sarcobatus spp.), creosote (Larrea tridentate), rabbit brush
(Crysothamnus spp.), cinquefoil (Potentilla simplex), snowberry (Symphoricarpos albus),
and elderberry (Sambucus spp.). Primary associated tree species is juniper (Juniperus
spp.).”

“Shrublands at 670-3,150 m (2,200-10,300 ft) elevation principally dominated by
greasewood (Sarcobatus vermiculatus), shadscale, graymolly (Kochia vestita), mat-
atriplex (Atriplex corrugata), Castle Valley clover (Atriplex cuneata), winterfat, budsage
(Artemisia spinescens), four-wing saltbush (Atriplex canescens), halogeton (Halogeton
glomeratus), Mormon tea (Ephedra spp.), horsebrush (Tetradymia canescens),
snakeweed and rabbitbrush; or low elevation perennial grassland co-dominate with
shrubland. Principal grassland species include: galleta, Indian ricegrass, three-awn grass
(Aristida glauca) and sand dropseed. Primary associated forb species include: desert
trumpet (Eriogonum inflatum). Primary associated shrub species include: sagebrush, and
black brush (Coleogyne ramosissima); other associated species include seepweed
(Suaeda torreyana).”

Based on the report by Lupis et al. (2007) we agree that the habitat that will be created at the Mill
site following revegetation will include species consistent with prairie dog occupation.

Table D.37 presents an updated assessment of maximum burrow depths for animal species that
may occur on the Mill site. Based on a review of literature for burrow depths, the species that
have the potential for the deepest burrows are badger (228 cm), northern pocket gopher (150
cm), and Gunnison prairie dog (427 cm). As discussed above, both the badger and Gunnison
prairie dog were observed during the 2012 animal survey, while there is no evidence that the
northern pocket gopher occurs in the vicinity of the Mill site from both the 1978 and 2012 surveys.

The proposed cover system is a monolithic evapotranspiration (ET) cover that consists of the
following layers from top to bottom: 15 cm of a topsoil-gravel erosion protection layer over 107

cm of a water storage, biointrusion and radon attenuation layer over 75 cm of a highly compacted
radon attenuation layer over 75 cm of a grading and radon attenuation layer. The proposed cover
system does not contain a biobarrier (e.g. cobble layer) to minimize potential intrusion by
burrowing animals. The proposed cover system is designed to minimize burrowing animal
intrusion through the use of thick layers of soil cover in combination with a highly compacted layer
placed at a depth that is below the expected burrowing depths among species that may inhabit
the site. The thickness of the cover (total of 272 cm), the use of a highly compacted radon
attenuation layer located at a depth between 122 and 197 cm, and a final 75 cm layer below the
compacted zone will all contribute to minimizing any biointrusion through the cover. Considering
the animal species that may inhabit the tailings cells and the thickness and physical nature of the
cover, it is not anticipated that burrowing will extend below 122 cm or into the very top portion of
the highly compacted zone. Burrowing into the highly compacted radon attenuation layer that
begins at a depth of 122 cm will be restricted because of the high density of this material (95
percent Standard Proctor).

D.6 SOIL REQUIREMENTS FOR SUSTAINABLE PLANT GROWTH
There are two key components to establishing an ET cover with a sustainable plant community.
The first is to select long-lived species that are adapted to the environmental conditions of the
site. The second is to provide a cover soil that will function as an effective plant growth medium
over the long term by supplying plants with adequate amounts of water, nutrients and rooting
volume.

Updated Tailings Cover Design Report

Energy Fuels Resources (USA) Inc. MWH Americas, Inc.
D-26 August 2015
There are a number of soil characteristics that are particularly important to achieve long-term
sustainability in semi-arid environments and include the following: pH, electrical conductivity
(EC), sodium levels, percent organic matter, texture, bulk density, cation exchange capacity,
macronutrient concentrations, available water holding capacity, and soil microorganisms. Table
D.38 presents levels for most of these soil properties that are considered necessary for long-term
sustained plant growth. In addition, the table includes soil property levels from soil samples of
potential cover soil collected from stock piles at the Mill site in May 2009.
The soil properties of the potential cover soil that are acceptable for sustaining long-term plant
growth include: pH, EC, sodium adsorption ratio (SAR), percent clay content, and extractable
phosphorus. Those soil properties that appear to be deficient and would need improvement
include: percent organic matter, total nitrogen, and extractable potassium.
Cation exchange capacity was not measured in the potential cover soil, but it is believed that the
cover soil will have an acceptable level for sustained plant growth based on the percent clay
content and a recommendation that an organic matter amendment be added to the soil during the
reclamation process. Bulk density of the emplaced cover material will be specified in the cover
design and will be controlled during the construction process to be within the sustainability range
shown in Table D.38.

†Calculated values
In order for the potential cover soil to function as a normal soil and provide long-term sustainable
support for the vegetation component of the ET cover, it will be amended to improve organic
matter content, nitrogen and potassium levels. An organic matter amendment will also improve
available water holding capacity and cation exchange capacity. The proposed organic
amendment is composted biosolids. Composted biosolids have been successfully used in mined
land reclamation over the past 40 years. This amendment would also provide a source of soil
microorganisms that will function to cycle nutrients over time and ensure sustainable plant growth.
Composted biosolids would be applied at a rate of 10 tons/acre and incorporated into the upper
six inches of the water storage layer of the cover system. Composted biosolids are also a source

Updated Tailings Cover Design Report

D-27 August 2015
of nitrogen, phosphorous and potassium and will serve to improve organic matter content and soil
fertility. The following discussion provides the rationale for selecting composted biosolids as the
amendment of choice for the cover soil.
Type of Amendment, Application Rates, and Costs – There are three possible soil amendments
that would be a source of organic matter and nutrients for sustained plant growth. These
amendments include composted biosolids, a combination of manure and hay, or a commercial
organic fertilizer such as Biosol®. Biosol® is a highly effective organic amendment but would be
cost prohibitive if the objective is to achieve 1 percent organic matter content in the soil. It would
require the addition of at least 10 tons/acre to meet this organic matter target and the cost would
be approximately $12,300/acre, which includes a product cost of $12,000/acre, transportation
cost of $100/acre, and an application cost of $200/acre. Composted biosolids would be equally
effective as Biosol®, but much less expensive. Composting of biosolids is a proven method for
pathogen reduction and results in a product that is easy to handle, store, and use. The end product
is usually a Class A, humus-like material without detectable levels of pathogens that can be
applied as a soil amendment. Composted biosolids provide large quantities of organic matter and
nutrients (such as nitrogen and phosphorus) to the soil, improves soil texture, and elevates soil
exchange capacity. If composted biosolids were obtained from Farmington, NM (which appears
at this time to be the closest source), the cost for a 10 ton/acre application rate would be
$1,530/acre, which includes $260/acre for product cost, $1,070/acre for transportation, and
$200/acre for application. The use of manure and hay would be the least effective amendment
because both products have the potential of adding unwanted weed seed to the cover vegetation
and manure is relatively high in nitrogen and if not properly off set with hay, there is a potential of
having excessive nitrogen introduced into the cover system that would also lead to a proliferation
of unwanted weeds.

Method of Application – Composted biosolids are produced by mixing biosolids (treated sewage
sludge) and wood waste material. Composted biosolids are easy to apply and would be broadcast
over the soil surface using a commercial manure spreader and the amendment would then be
incorporated with a chisel plow or disc plow.

Limitations of Soil Amendments – Composted biosolids have few limitations as a soil amendment.
Composted biosolids are often low in readily available nitrogen, but have high organic nitrogen
levels that can be slowly released for plant use over time. The EPA has established rules for the
land application of biosolids that address concerns about possible pathogen transmittal, nitrate
pollution, and trace metal contamination (EPA, 1993 and 1995). In order to be land applied, a
particular biosolid must have undergone a pathogen reduction process, must contain less than a
specified amount of bacterial pathogens, and must meet limits for heavy metal concentration.

Considerable research has been conducted over the past 40 years on the interactions between
biosolids, soil properties, plant growth and environmental quality. Amendment of disturbed soils
with composted biosolids has been shown to increase soil organic matter, cation exchange
capacity, soil nutrient levels, microbial biomass and activity, water holding capacity, and
aggregate stability, and also to reduce soil bulk density and metal availability for plant uptake.
The potential for successful reclamation with composted biosolids is tremendous and most of the
highly beneficial properties of composted biosolids as a soil amendment come from its high
organic matter content (Sopper, 1993). The use of composted biosolids is extremely important
where topsoil is inadequate in amount or quality (Sopper, 1993; Munshower, 1994).

Updated Tailings Cover Design Report

Energy Fuels Resources (USA) Inc. MWH Americas, Inc.
D-28 August 2015
The application of composted biosolids on disturbed land generally has had a very beneficial
effect on the establishment and growth of grasses and forbs (Sopper, 1993; Haering et al., 2000).
It facilitates rapid establishment and vigorous growth of herbaceous plants. Sites treated with
composted biosolids generally have a greater percent cover, greater aboveground production,
and better developed root systems compared to non-amended sites or sites treated with just
inorganic fertilizers (Sopper, 1993; Haering et al., 2000). The use of composted biosolids also
aids in the establishment and growth of shrubs. Annual height and diameter growth is improved
with composted biosolids and overall woody plant survival is increased if competition from
herbaceous plants is not an issue (Sopper, 1993; Haering et al., 2000).

Field studies at the Climax Molybdenum Mine near Leadville, Colorado conducted by Carlson et
al. (2006) examined the effect of composted biosolids on tailings reclamation over a seven-year
period. The findings of this study were that composted biosolids are an effective means of
establishing soil microbe and vegetation communities on tailings. The authors concluded that:
over seven years and in extreme growing conditions, biosolid amendments reduced soil toxicity
[by immobilizing heavy metals], neutralized acidity, and introduced constituents [e.g. nutrients and
soil microbes] necessary to sustain vegetation communities on tailings capped with overburden
material.

In a very long-term study conducted by Paschke et al. (2005) the effect of biosolids amendments
were assessed on disturbances in a sagebrush community in northwestern Colorado. The
authors reported that 24 years after biosolids were applied on fertile and infertile soil material that:
“… biosolids amendments have long-lasting effects on soil fertility and plant community
composition…”

The greatest limitation for the use of composted biosolids at the Mill site will be availability of the
product. Availability varies over time depending upon supply and demand. Since the Mill site is
in a remote location, sources of composted biosolids in the quantities needed for tailing cell
reclamation are limited and advanced planning will be required to secure the quantities needed
when the cover system is being constructed.

D.7 WEED MANAGEMENT
Weed management would be conducted on the Mill site by identifying the presence of any noxious
weeds during annual vegetation surveys and developing a weed control plan that is specific to
the species that are present (Table D.39). Noxious weed control is species dependent and both
method and timing will vary from species to species.
Each survey will identify noxious weed populations and locate these populations on a map using
a set of symbols to identify species, size of the infestation, and density of the population. The
effectiveness of control methods will also be documented in each annual survey. In addition,
immediately adjacent off-site properties will be visually surveyed to a distance of 100 feet.
Inspections will be conducted by personnel familiar with the identification of noxious weeds in the
area and based on Utah’s Noxious Weed List.
The selected control methods will be based on the type, size, and location of the mapped noxious
weeds. The treated area(s) will be monitored and re-inspected annually for new weed
introductions and to evaluate the success of the control methods. Prevention is the highest priority
weed management practice on non-infested lands; therefore protecting weed-free plant
communities is the most economical and efficient land management practice. Prevention is best
accomplished by ensuring that new weed species seed or vegetative reproductive plant parts of

weeds are not introduced into new areas, and by early detection of any new weed species before
they begin to spread.
Control methods may include chemical or mechanical approaches. The optimum method or
methods for weed management will vary depending on a number of site-specific variables such
as associated vegetation, weed type, stage of growth, and severity of the weed infestation.

Chemical Control
Chemical control consists mostly of selective and non-selective herbicides. Considerations for
chemical controls include: herbicide selection, timing of application, target weed, desirable plant
species being grown or that will be planted, number of applications per year and number of years
a particular species will need to be treated for desired control. Also important are the health and
safety factors involved, and the need to consider undesirable impacts. The use of herbicides will
be in compliance with all Federal and State laws on proper use, storage, and disposal. The
chemical application will be done by a licensed contractor in accordance with all applicable laws
and regulations and all label instructions will be strictly followed. Applications of herbicides would

not be permitted when the instructions on the herbicide label indicate conditions that are not
optimal.

Mechanical Control
Mechanical control is the physical removal of weeds from the soil and includes tilling, mowing,
and pulling undesirable plant species. Tillage is most effective prior to seeding and establishment
of desirable vegetation. The tillage method of weed control can be effective in eliminating noxious
perennial weeds when repeated at short intervals (every 1-2 weeks) throughout the growing
season. Tillage has the drawback of indiscriminately impacting all vegetation interspersed with
weeds in established areas and can eliminate competitive, desirable vegetation leaving behind a
prime seedbed for weeds to reinvade. Mowing can be an effective method for controlling the
spread of an infestation and preventing the formation and dispersal of seeds. Mowing is most
effective on weeds which spread solely or primarily by seed. In order to achieve this, it must be
repeated at least twice during the growing season prior to, or shortly after bloom. Also, even the
most intense mowing treatment will not kill hardy perennial weeds. Additional considerations will
be made when selecting control treatments when specific situations arise regarding type, size,
and location of weed infestations. Examples of this are perennial versus biennial, broadleaf versus
grasses, noxious weeds interspersed with desirable vegetation, large monoculture patches, or
small patches requiring spot treatment.

Treatment windows schedules, based on the control methods chosen and the noxious weeds
present, will be established for each treatment area. The best time to treat perennial noxious
weeds is in the spring or fall during their active growth phase. Different species will have different
optimum treatment times even with the same type of control. Perennial weeds usually grow
vegetatively in the spring, flower and seed in late spring and early summer, enter dormancy during
the summer and actively grow again in the fall. The treatment windows selected will depend on
the species present and control methods selected.

The final preparatory step is to determine the priority for areas to be treated. Prioritization ensures
that the most important areas are dealt with at the most effective times. Important areas of concern
include areas that may transport weed seeds. These areas include ditches, roadsides, and land
equipment storage sites. Large monoculture patches are of concern wherever they occur and
would always be high priority. Also, small patches of weeds would be treated to prevent expansion
of weed populations.

Once the treatment plan is implemented, detailed records will be kept, and success or failure of
treatment will be recorded so as to eliminate unsuccessful treatments.

D.8 REVEGETATION ACCEPTANCE GOALS/CRITERIA AND MONITORING

The following Revegetation Acceptance Goals/Criteria have been adapted from the Monticello
Site and would be used at the Mill site to determine reclamation success.

Criterion 1 Species Composition
a. The vegetative cover (the percentage of ground surface covered by live plants) shall be
composed of a minimum of five perennial grass species (at least four listed as native),
one perennial forb and two shrub species listed in Table D.1.

Updated Tailings Cover Design Report

Energy Fuels Resources (USA) Inc. MWH Americas, Inc.
D-31 August 2015
Criterion 2 Vegetative Cover
a. Attain a minimum vegetative cover percentages of 40 percent.

b. Individual grass and forb species listed in Table D.1 that are used to achieve the cover
criteria shall have a minimum relative cover (the cover of a plant species expressed as a
percentage of total vegetative cover) of 4 percent and a maximum relative cover of 40
percent.

c. Individual species not listed in Table D.1 may be accepted as part of the cover criteria if
it is demonstrated that the species is native or adapted to the area and is a desirable
component of the reclaimed project site.

d. Species not listed in Table D.1, including annual weeds or other undesirable species
shall not count toward the minimum vegetative cover requirement. Every attempt should
be made to minimize establishment of all non-noxious weeds.

e. Reclaimed areas shall be free of state- and county-listed noxious weeds (Table D.40).

f. The vegetative cover shall be self-regenerating and permanent. Self-regeneration shall
be demonstrated by evidence of reproduction, such as tillers and seed production.

Criterion 3 Shrub Density
a. A minimum shrub density of 500 stems per acre

b. Shrubs shall be healthy and have survived at least two complete growing seasons
before being evaluated against success criteria

Monitoring

Plant cover would be measured annually on the tailing cells for a minimum of ten years or until
the revegetation goals stated above are achieved. Cover would be measured by the point
method, using a vegetation sighting scope mounted on an adjustable tripod with a level (or similar
instrument). Cover would be measured for each species encountered, as well as litter, rock, and
bareground. Cover measurements would be made along a minimum of ten randomly placed
transects on each tailing cell that are 100 feet long. A total of 100 points would be sited at one-
foot intervals along each transect to collect cover data in the categories of live vegetation, litter,
rock, and bareground. Sample adequacy would be determined for each tailing cell using the
following formula that identifies the minimum number of samples that are necessary to estimate
the population mean at a 90 percent level of confidence. Total live vegetation cover would be
used to calculate sample adequacy.

n = t2s2

Where: n = minimum number of samples required to meet sample

adequacy requirements
s2 = variance
t2 = 1.64 for 90% confidence
x = sample mean

Shrub density would be measured in belt transects placed on either side of the cover transects.
All shrubs would be counted within a three-foot wide strip or belt transect along each side of the
transect used for point cover measurements, resulting in a belt transect that is six-feet wide and
100 feet long.
In addition to the above cover sampling, annual observations would be made of overall plant
community health and sustainability. Overall health would be based on plant vigor, presence of
annual weeds, and signs of plant deficiencies or toxicities. Plant community sustainability would
be based on observations of reproduction, including both vegetative reproduction, such as
tillering, and seed production.
If revegetated areas are not making satisfactory progress in meeting revegetation goals outlined
above, then remedial actions will be implemented as needed. These actions may include
fertilization/soil amendments, reseeding, weed control, and/or erosion control depending upon the
cause of the problem that may exist and the best remediation approach to ensure plant community
success. Potential revegetation problems that are most likely to occur based on typical
revegetation projects in the semiarid west and on experiences at the Monticello Site fall into two
categories. The first is poor initial plant establishment following revegetation practices and the
second is poor plant growth during post-revegetation management. Poor initial plant
establishment can be caused by a number of factors including unfavorable soil conditions related
to texture or soil chemistry, improper seedbed preparation, improper seeding techniques,
improper species selection, poor seed quality, planting in the wrong season, seed predation, and
inadequate precipitation. If revegetation at the Mill site results in unacceptable initial plant
establishment, the cause of this response will be investigated, the identified cause will be
corrected, and the necessary revegetation practices will be applied until successful plant
establishment has occurred. The most likely cause of poor initial plant establishment at the Mill
site would be low precipitation and additional seedings would be required in a subsequent year(s)
until precipitation improves and an adequate stand of vegetation is achieved. Additional mulching
to control erosion and improve soil moisture conditions for seed germination and initial seedling
growth would be part of the remedial process. Poor plant growth during post-revegetation
management has been an issue at the Monticello Site as it relates to shrub establishment. The
primary species that has been an issue is big sagebrush and the cause of the problem has been
seedling damage associated with vole herbivory.

D.9 SUSTAINABILITY OF THE COVER DESIGN
D.9.1 CLIMATE CHANGE
Climate, more than any other factor, controls the broadscale distributions of plant species and
vegetation. At finer scales, other factors such as local environmental conditions including soil
nutrient status, pH, water-holding capacity and the physical elements of aspect or slope influence
the potential presence or absence of a species. However, intra- and inter-specific interactions,
such as competition for resources (light, water, nutrients), ultimately determine whether an
individual plant is actually found at any particular location (Sykes 2009). Rapid climate change

D-33 August 2015
associated with increasing greenhouse gas emissions (IPCC 2007) influences current and future
vegetation patterns. Other human-influenced factors are, however, also involved. Sala et al.
(1997) identified five different drivers of change that can be expected to affect global biodiversity
over the next 100 years. Globally, land use change was considered the most important driver of
change, followed by climate change, airborne nitrogen deposition, biotic interactions (invasive
species) and direct CO2 fertilizing or water use efficiency effects.
Predicted changes in climate that may occur in the southwestern U.S. include increased
atmospheric concentrations of CO2, increased surface temperatures, changes in the amount,
seasonality, and distribution of precipitation, more frequent climatic extremes, and a greater
variability in climate patterns. Recent temperature increases have made the current drought in
the region more severe than the natural droughts of the last several centuries. This drought has
caused substantial die-off of pinyon pine trees in approximately 4,600 square miles of pinyon-
juniper woodland in the Four Corners region (Breshears et al. 2005). Williams et al. (2010)
examined correlations between climate and the radial growth of trees across North America. They
show that conifer trees in the southwest are particularly sensitive to temperature and aridity
relative to other regions. They used climate-tree growth relations calculated for the past 100
years, combined with Intergovernmental Panel on Climate Change (IPCC) climate model
estimates for the 21st century to predict the likely fate of important southwest tree species such
as pinyon pine. They concluded that woodlands and forests will experience substantially reduced
growth rates and increase mortality at many southwest sites as the century progresses.
The specific physiological effects of increasing GHG emissions (particularly CO2) on vegetation
include increased net photosynthesis, reduced photorespiration, changes in dark respiration, and
reduced stomatal conductance which decreases transpiration and increases water use efficiency
(Patterson and Flint 1990). Ambient temperature affects plants directly and indirectly at each
stage of their life cycle (Morison and Lawlor 1999). Water (i.e. soil moisture) is usually the abiotic
factor most limiting to vegetation, especially in arid and semi-arid regions. Carbon dioxide,
temperature, and soil moisture effects on plant physiology are exhibited at the whole-plant level
in terms of growth and resource acquisition. In addition to the individual effects of increasing
temperatures, CO2 is the additional interactive effect on photosynthetic productivity and
ecosystem-level process (Long and Hutchin 1991).
Plants are finely tuned to the seasonality of their environment, and shifts in the timing of plant
activity (i.e. phenology) provide some of the most compelling evidence that species and
ecosystems are being influenced by global environmental change (Cleland et al. 2007). Changes
in the phenology of plants have been noted in recent decades in regions around the world (Bradley
et al. 1999; Fitter and Fitter 2002; Walther et al. 2002; Parmesan and Yohe 2003). Phenology of
plant species is important both at the individual and population levels. Specific timing is crucial to
optimal seed set for individuals and populations; and variation among species in their phenology
is an important mechanism for maintaining species coexistence in diverse plant communities by
reducing competition for pollinators and other resources. Global climate change could
significantly alter plant phenology because temperature influences the timing of development,
both alone and through interactions with other cues, such as photoperiod.
Shifts in the relative competitive ability of plants that experience changes in CO2, surface
temperatures, or soil moisture may result in changes to their spatial distribution (Long and Hutchin
1991; Neilson and Marks 1994). Increases in temperature may enhance the competitive ability
of C4 plants (such as grasses) relative to C3 plants (shrubs and trees) (Owensby et al. 1999),
especially where soil moisture (Neilson 1993) or temperature (Esser 1992) is limiting.

There are numerous uncertainties and complexities associated with the use of all regional climate
models with regard to their ability to reliably forecast longer-term future climate conditions in the
North American South West (NASW) and at the Mill site. Therefore, attempts to extend the results
from climate model predictions forecasting climate conditions through the end of the 21st century
to timeframes of 200 to 1,000 years will likely result in further compounding of these uncertainties
and result in unreliable predictions. We identified this concern in earlier discussions presented
on the topic of climate change.
We have reviewed references cited in the Division’s Rd 1 Interrogatories for White Mesa Revised
ICTM Report on estimating the range of future climates (CNRWA 2005; NRC 2003; NRC 1997).
The Center for Nuclear Waste Regulatory Analyses (CNRWA 2005) conducted an analysis of
factors contributing to uncertainty in estimating future climates at Yucca Mountain. Their report
concludes the following:

“In summary, research performed within the last five years suggests that the timing of
climate changes over the next 100,000 years may be difficult to infer from the patterns of
climate change over the last 500,000 years due to the unusually low eccentricity of Earth’s
orbit and, possibly, the influence of anthropogenic greenhouses gases. After 100,000
years, the Earth’s orbital climate forcing will be stronger, and the influence of greenhouse
gases may have diminished so that the Pleistocene climate history may offer a better
analog in terms of timing of climate changes. In terms of the characteristics of future
climates (i.e., mean annual precipitation and temperature, seasonal weather patterns, and
storm intensities), the characteristics inferred from paleoclimate reconstructions and
present day analog records may represent the range of climate conditions that will occur
in the future, even if the timing of these climates cannot be reliably estimated. The greatest
uncertainty in future climate conditions relates to anthropogenic effects that may result in
climates in southern Nevada that do not have analogs with present or Pleistocene
climates, such as prolonged El Niño conditions. The nature, likelihood, and duration of
such nonrepresentative climate conditions cannot be reliably assessed based on current
research. Over longer time periods, the range of conditions inferred from the Pleistocene
paleoclimate record reasonably bounds future climate during the period of geologic
stability.”

We agree with NRC’s preferred approach of using paleoclimate data to estimate the likely range
of future conditions. In fact, in our previous discussion of climate change in Attachment G (EFRI,
2012), we discussed the paleoclimate approach presented by Waugh and Petersen (1994) for
the Monticello site.

Waugh and Petersen (1994) summarize future climate change as follows:

“Global mean temperature may increase by 1.8 to 5.2oC in the next century, in response
to an industrial age buildup of carbon dioxide (CO2), methane, and other gases (Houghton
et al. 1992). Model projections of the magnitude of warming vary, depending on whether
factors such as CO2 fertilization, feedback from stratospheric ozone depletion, and the
radiative effects of sulfate aerosols are taken into account. Model projections of
precipitation responses to greenhouse warming also are inconsistent (Houghton et al.
1990; Crowley and North 1991; Washington and Meehl 1984; Wilson and Mitchell 1987;
Schlesinger and Mitchell 1987). Some regions may be effectively wetter and others drier,
depending on the balance of the greater potential evaporation and the greater water-
holding capacity of a warmer atmosphere. Greenhouse warming may eventually be
overwhelmed as the earth plunges into another ice age. Models of cyclic astronomical

forcing of climate agree that, without anthropogenic disturbances, a long-term cooling
trend that started about 6,000 years ago will continue, climaxing with a major glaciation in
about 60,000 years (Imbrie and Imbrie 1980; Berger et al. 1991). In contrast, aperiodicity
in the timing of past ice ages is evident in oxygen isotope records (Winograd et al. 1992).
Other paleorecords suggest that certain feedback mechanisms have caused rapid and
unpredictable transitions into ice ages (Berger and Labeyrie 1987; Phillips et al. 1990).”

Waugh and Petersen (1994) concluded from their investigation that despite uncertainty about
drivers of future climate change, climate extremes in the next 1,000 years likely will not exceed
those associated with the last glacial and interglacial periods. Therefore, paleo-records of full
glacial and Altithermal climates in the Four Corners region provide reasonable ranges of possible
future climate and should be incorporated in assessments of the long-term performance of tailings
disposal facilities. For Monticello, Utah, full glacial and Altithermal climate reconstructions provide
working levels of 2 to 10o C mean annual temperature and 38 to 80 cm mean annual precipitation.
If we assume that a similar range of temperature and precipitation could also occur at the Mill site,
then during the next glacial phase anticipated to occur approximately 60,000 years into the future
the climate would be a colder and wetter compared to current conditions, and if conditions post-
glaciation result in a warm period the climate would be warmer and wetter than current conditions.
Table D.41 presents a list of possible climate scenarios for the Mill site, their likelihood of
occurrence and the resulting plant community type that would develop during the required
performance period. From the review of climate change literature applicable to the southwest
U.S. and an analysis of the impact of various climate change scenarios, it is our conclusion that
the most likely plant community type that will be maintained throughout the 200- to 1,000-year
performance period is a community dominated initially by cool season grasses, with a long-term
transition to dominance by warm season grasses and shrubs as atmospheric CO2 and
temperature continues to increase and precipitation ether increases or decreases.
D.7.2 Plant Community Succession and Potential for Species Colonization
Plant succession is the ecological process of directional vegetation change over time, usually
beginning with relatively-short lived herbaceous plants and culminating in plant communities
dominated by long-lived, generally woody species. Succession occurs on all sites. The rate of
succession can be relatively rapid, especially in regions of higher rainfall, or it can be very slow,
as in some desert and arctic regions, but this process of vegetation change is constantly taking
place.
Two common aspects of succession are 1) an increase in vegetation structure and 2) an increase
in the relative amounts of woody plants. Both of these aspects have profound implications to the
function of cover systems. Vegetation structure refers to the shape of the vegetation, e.g., height,
coverage, and stratification. Structure increases as succession proceeds, both above- and
belowground. Aboveground, the height of the vegetation increases (e.g., grasses may be
replaced by shrubs), coverage of the soil surface increases, and layering (strata) of vegetation
occurs, with different species occupying different vertical layers. Similar processes occur
belowground. Root systems become deeper as shallow-rooted species are replaced by deeper-
rooted species, root biomass increases in lower soil depths as the number and types of species
increase, and the density of the root system increases in the various layers.

Seager and Vecchi 2010, with a focus on the southwest U.S.
As the vegetation shifts from dominance by herbaceous plants (e.g., grasses), which have
relatively shallow root systems but with very dense root mass in the upper profile, to dominance
by woody species (e.g., shrubs), which have deeper roots systems with proportionately more
roots in deeper layers, the hydrological dynamics of the system change. Early successional plant
communities tend to extract most of the water they transpire from the upper soil profile. Late
successional communities have greater ability to extract water from depth. This can be both a
positive and a negative in the functional efficiency of covers. Because of successional changes
in the vegetation, the plant-soil-water characteristics of a cover are likely to become very different
over time. Conditions 200 years or more after construction are not likely to be similar to those
soon after construction was completed. In some ways, conditions will be more favorable, e.g.,

Updated Tailings Cover Design Report

D-37 August 2015
evapotranspiration will likely be higher thus reducing the amount of deep infiltration and stability
of the vegetation may be greater. In other ways, conditions will be less favorable, e.g., deeper
root systems increase the concern for biointrusion. Because succession is a process that is near-
universal ecologically, these changes have been accounted for in the cover design.
As stated earlier, the proposed cover system is a monolithic ET cover that consists of the following
layers from top to bottom: 15 cm of a topsoil-gravel erosion protection layer over 107 cm of a
water storage, biointrusion and radon attenuation layer over up to 110 to 136 cm of a highly
compacted radon attenuation layer over 76 cm of a grading and radon attenuation layer. The
proposed cover system does not contain a biobarrier (e.g. cobble layer) to minimize potential
intrusion by plant roots during the required performance period. The proposed cover system is
designed to minimize plant root intrusion through the use of thick layers of soil cover in
combination with a highly compacted layer placed deep within the cover. The climax community
for the Mill site is believed to be Big Sagebrush based on the current community type at the site
and the relatively deep fine loamy soils that are present. If climate trends towards a warmer and
dryer climate for the White Mesa area over the next 200 to 1,000 years, it is unlikely that
sagebrush will remain on site and a community dominated by warm season species and more
arid shrub species (e.g. shadscale saltbush, blackbrush and Mormon tea) may occur.
As discussed above, the process of succession and the effect of climate change will bring about
changes in species composition in the tailings cover system. Our best forecast for the percentage
of potential species colonization would be for a small percent of non-seeded species establishing
during the first 50 years. The seeded community will be highly sustainable and big sagebrush
would be the primary invader into the cover system. It is estimated that the established community
will consist of 60 to 70 percent seeded species and 30 to 40 percent non-seeded species at end
of the first 100 years. These non-seeded species will include big sagebrush and broom
snakeweed, and a few grass and forb species common in the area. During the next 100 years
the plant community will begin to transition to warm season species and big sagebrush will begin
to diminish. By the end of the second 100 years it is estimated that the plant community will
consist of 30 to 40 percent seeded and 60 to 70 percent non-seeded species and many of the
non-seeded species will be warm season grasses and more arid shrub species. This trend will
most likely continue through the remainder of the performance period with only 10 to 20 percent
of the original seeded species still present and these would include blue grama and galleta. The
remainder of the community would consist of more warm season grasses and shrubs that will
have migrated north and higher in elevation with the warming climate.

J.1 INTRODUCTION
Revegetation of the tailing cells at the White Mesa Mill Site will be completed following
construction of the cover system. The revegetation process will establish a grass-forb-shrub
community consisting primarily of native, long-lived perennial grasses, forbs, and shrubs that
are highly adapted to the climatic and edaphic conditions of the site. Revegetation methods will
follow state-of-the-art techniques for soil amendments, seedbed preparation, seeding and
mulching. In addition, quality assurance and quality control procedures will be followed to
ensure that revegetation methods are implemented correctly and the results of the process
meet expectations.

J.2 PLANT SPECIES AND SEEDING RATES
The following 15 species (11 grasses, 2 forbs, and 2 shrubs) are proposed for the ET cover
system at the White Mesa Mill site. These species were selected for their adaptability to site
conditions, compatibility, and long-term sustainability. Species were also selected based on the
assumption that institutional controls will exclude grazing by domestic livestock. The proposed
species are:
 Western wheatgrass, variety Arriba (Pascopyrum smithii)
 Bluebunch wheatgrass, variety Goldar (Pseudoroegneria spicata)
 Slender wheatgrass, variety San Luis (Elymus trachycaulus)
 Streambank wheatgrass, variety Sodar (Elymus lanceolatus ssp. psammophilus)
 Pubescent wheatgrass, variety Luna (Thinopyrum intermedium ssp. barbulatum)
 Indian ricegrass, variety Paloma (Achnatherum hymenoides)
 Sandberg bluegrass, variety Canbar (Poa secunda)
 Sheep fescue, variety Covar (Festuca ovina)
 Squirreltail, variety Toe Jam Creek (Elymus elymoides)
 Blue grama, variety Hachita (Bouteloua gracilis)
 Galleta, variety Viva (Hilaria jamesii)
 Common yarrow, no variety (Achillea millefolium)
 White sage, variety Summit (Artemisia ludoviciana)
 Fourwing saltbush, variety Wytana (Atriplex canescens)
 Rubber rabbitbrush (Ericameria nauseosus).

The ecological characteristics of these species are described in detail in Appendix D.

Table J.1 presents broadcast seeding rates for each species. Seeding rates were developed
based on the objective of establishing a permanent cover of grasses, forbs, and shrubs in a
mixture that would promote compatibility among species and minimize competitive exclusion or
loss of species over time. Seeding rates were developed on the basis of number of seeds per
unit area (e.g. number of seeds per square foot) and then converted to weight per unit area (e.g.
pounds per acre).

†Seeding rate is for broadcast seed and presented as pounds of pure live seed per acre (lbs PLS/acre).
‡Introduced refers to species that have been ‘introduced’ from another geographic region, typically
outside of North America. Also referred to as ‘exotic’ species. * VNS=Variety Not Specified but seed
source would be designated from sites similar to the Mill Site.

Seeding rates are calculated from an expected field emergence for each species and the
desired number of plants per unit area. For purposes of calculation, field emergence for small
seeded grasses and forbs is assumed to be around 50 percent if germination is greater than 80
percent. Field emergence is assumed to be around 30 percent if germination is between 60 and
80 percent. The Natural Resource Conservation Service recommends a seeding rate of 20 to
30 pure live seeds per square foot as a minimum number of seeds when drill seeding single
species in areas with an annual precipitation between 6 and 18 inches. Twenty pure live seeds
per square foot, with an expected field emergence of 50 percent should produce an adequate
number of plants on the seeded area to control erosion and suppress annual invasion. This
seeding rate is primarily for favorable growing conditions, soils that are not extreme in texture,
gentle slopes, north or east facing aspect, good moisture, adequate soil nutrients and single
species vs. multiple species in a mixture. When conditions are less favorable when the seed is
broadcast, or when multiple species are in a mixture the seeding rates are increased.

A Quality Assurance/Quality Control Plan for application rates and procedures for confirming
that specified application rates are achieved is as follows. The first step begins with a seed
order. Seed would be purchased as pounds of pure live seed. Each State has a seed certifying
agency and certification programs may be adopted by seed growers. Certification of a container

of seed assures the customer that the seed is correctly identified and genetically pure. The
State agency responsible for seed certification sets minimum standards for mechanical purity
and germination for each species of seed. When certified, a container of seed must be labeled
as to origin, germination percentage, date of the germination test, percentage of pure seed (by
weight), other crop and weed seeds, and inert material. The certification is the consumer’s best
guarantee that the seed being purchased meets minimum standards and the quality specified.

Once the seed is obtained, seed labels would be checked to determine the percent PLS and the
date that the seed was tested for percent purity and percent germination. If the test date is
greater than 6 months old, the seed would be tested again before being accepted. Seed will be
applied using a broadcasting method as described below.

J.3 SOIL FERTILIZATION AND ORGANIC MATTER AMENDMENT
The physical and chemical characteristics of the soil that will be used for the cover system are
presented in Appendix D. Based on this analysis, there are three soil properties that appear to
be deficient for sustained plant growth and will need to be treated prior to seeding and to ensure
that the soil provides adequate carbon and plant essential nutrients for initial plant
establishment and long-term sustainability. The soil properties that will need treatment include
percent organic matter, total nitrogen, and plant available potassium (Appendix D). The upper
15 cm of the water storage layer will be treated with an organic matter amendment to alleviate
the existing deficiencies. This treatment will be applied after the water storage layer is in place
and before placement of the topsoil-gravel erosion protection layer. Further chemical analysis
will be conducted prior to placement of the water storage layer to verify the chemical properties
of this material and to finalize the proposed treatment. In order for the potential cover soil to
function as a normal soil and provide long-term sustainable support for the vegetation
component of the ET cover, it will be amended to improve organic matter content, nitrogen and
potassium levels. An organic matter amendment will also improve available water holding
capacity and cation exchange capacity. The proposed organic amendment is composted
biosolids. Composted biosolids have been successfully used in mined land reclamation over
the past 40 years. This amendment would also provide a source of soil microorganisms that will
function to cycle nutrients over time and ensure sustainable plant growth. Composted biosolids
would be applied at a rate of 10 tons/acre and incorporated into the upper six inches of the
water storage layer of the cover system. Composted biosolids are also a source of nitrogen,
phosphorous and potassium and will serve to improve organic matter content and soil fertility.  

The topsoil-gravel erosion control layer will not be amended for organic matter or nutrients to
avoid the stimulation of undesirable weedy species. The addition of nutrients, especially
nitrogen, during revegetation is known to stimulate the growth of annual weeds at the potential
detriment of seeded perennial species. Withholding nutrient additions from the topsoil-gravel
cover will allow the seeded species to establish without the unwanted competition from
undesirable weedy species.

J.4 SEEDBED PREPARATION
Following placement of the topsoil-gravel erosion protection layer, the area will be harrowed to
reduce any compaction that may have occurred during placement of the cover and to create an
uneven surface for optimum seedbed conditions. Since seeding will be conducted with a
broadcast method it is critical for the soil surface to be loose and uneven, but also have a

firmness below the soil surface to allow proper seeding depth and to promote optimum seed-soil
contact for germination and initial plant establishment.

J.5 SEEDING
Seed will be applied using a broadcasting method as soon as practicable following seedbed
preparation. This procedure will use a centrifugal type broadcaster (or similar implement), also
called an end-gate seeder. These broadcasters operate with an electric motor and are usually
mounted on the back of a small tractor and generally have an effective spreading width of about
20 feet or more. Prior to seeding, a known area will be covered with a tarp and seed will be
distributed using the broadcaster and simulating conditions that would exist under actual
seeding conditions. Seed will then be collected and weighed to determine actual seeding rate in
terms of pounds per acre. This process will be repeated until the specified seeding rate is
obtained. During the seeding process, the seeding rate will be verified at least once by
comparing pounds of seed applied to the size of the area seeded. In addition, seed will be
applied in two separate passes. One-half of the seed will be spread in one direction and the
other half of seed will be spread in a perpendicular direction. This will ensure that seed
distribution across the site is highly uniform and also provide the opportunity to adjust the
seeding rate if the specified rate is not being achieved. Seeding will not occur if wind speeds
exceed 10 mph.

Immediately following seeding, the area will be lightly harrowed to provide seed coverage and to
maximize seed-soil contact. This step in the revegetation process will ensure that the seed is
placed at an optimum seeding depth and in good soil contact for proper germination conditions.

Seeding will take place as soon as practical after the cover system is in place. Successful
seeding in southeastern Utah can occur either in late fall (e.g. October) as a dormant seeding,
with germination and establishment occurring the following spring or can be conducted in June,
prior to the summer monsoon season. The timing for seeding will be dependent upon the
construction schedule for the cover system.

J.6 MULCHING
A mulch will be applied immediately following seeding to conserve soil moisture for seed
germination and initial plant establishment. Mulching will also provide additional soil erosion
protection from both wind and water until a plant cover is established. A weed-free, wood-fiber
mulch will be applied to the seeded area at a rate of 1.5 tons/acre. Wood fiber mulch will
consist of specially prepared wood fibers and will not be produced from recycled material such
as sawdust, paper, cardboard, or residue from pulp and paper plants. The fibers will be dyed an
appropriate color, non-toxic, water-soluble dye to facilitate visual metering during application.
Wood fiber mulch will be supplied in packages and each package will be marked by the
manufacturer to show the air-dry weight.

The wood fiber mulch will be applied by means of hydraulic equipment that utilizes water as the
carrying agent. The mulch will be applied in a uniform manner at a minimum rate of 1.0
ton/acre. A continuous agitator action, that keeps the mulching material and approved additives
in uniform suspension, will be maintained throughout the distribution cycle. The pump pressure
will be capable of maintaining a continuous non-fluctuating stream of slurry. The slurry
distribution lines will be large enough to prevent stoppage and the discharge line will be
equipped with a set of hydraulic spray nozzles that will provide an even distribution of the mulch

slurry to the seedbed. Mulching will not be done in the presence of free surface water resulting
from rains, melting snow, or other causes.

A tackifier will be used with the wood fiber mulch to improve adhesion. The tackifier will be a
biodegradable organic formulation processed specifically for the adhesive binding of mulch. In
addition, the tackifier will uniformly disperse when mixed with water and will not be detrimental
to the homogeneous properties of the mulch slurry. Tackifier may be added either during the
manufacturing of the mulch or incorporated during mulch application. Tackifier will have
characteristics of hydrating and dispersing in circulating water to form a homogeneous slurry
and remain in such a state in the hydraulic mulching unit when mixed with the wood fiber mulch.
When applied, the tackifier will form a loose chain-like protective film, but not a plant inhibiting
membrane, which will allow moisture to percolate into the underlying soil, while helping bind
seeds to the soil surface during germination and initial seedling growth, after which the tackifier
will break down through natural processes.

PLAN, REVISION 5.0)

Updated Tailings Cover Design Report

APPENDIX C

RADON EMANATION MODELING

Energy Fuels Resources (USA), Inc. MWH Americas, Inc.
C-1 August 2015
C.1 BACKGROUND

This appendix presents the results of modeling the emanation of radon-222 from the top surface
of the proposed cover over the White Mesa tailing impoundments to achieve the State of Utah’s
long-term radon emanation standard for uranium mill tailings (Utah Administrative Code, Rule
313-24). These results comprise an update of radon emanation modeling presented in
Attachment F of the 2009 Reclamation Plan (Denison, 2009) and Appendix H of the Infiltration
and Contaminant Transport Modeling Report (Denison, 2010), as well as an update to Appendix
C of the 2011 Updated Tailings Cover Design report (MWH, 2011). This appendix provides a
summary of additional analyses of radon attenuation through the proposed evapotranspiration
(ET) cover, and incorporates the revised cover grading design, results of cover material testing
conducted in 2010 and 2012 (summarized in Attachment B of EFRI, 2012), and results of
tailings testing conducted in 2013 (presented in MWH, 2015).

The final version of this appendix will be provided as Appendix C to the next version of the
Updated Tailings Cover Design report. The Updated Tailings Cover Design report will be
submitted as an attachment to the next version of the Reclamation Plan.

The monolithic ET cover system evaluated in this appendix consists of the following layers from
top to bottom:

 0.5 ft (15 cm) Erosion Protection Layer (gravel-admixture or topsoil)
 3.5 ft (107 cm) Water Storage/Biointrusion/Frost Protection/Radon Attenuation Layer
(loam to sandy clay)
 3.0 to 4.0 ft (91 to 122 cm) Radon Attenuation Layer (highly compacted loam to sandy
clay)
 2.5 ft (76 cm) Radon Attenuation and Grading Layer (loam to sandy clay)

The loam to sandy clay soil used to construct the ET cover, referred to in previous reports (Titan
1996, Knight Piesold 1999) as random/platform fill, is stockpiled at the site.
C.2 DESCRIPTION OF MODEL AND INPUT VALUES

The thickness of the reclamation cover necessary to limit radon emanation from the disposal
areas was analyzed using the NRC RADON model (NRC, 1989). The model utilizes the one-
dimensional radon diffusion equation, which uses the physical and radiological characteristics of
the tailings and overlying materials to calculate the rate of radon emanation from the tailings
through the cover. The model was used to calculate the cover thickness required to limit the
radon emanation rate through the top of the cover to 20 picocuries per square meter per second
(pCi/m2-s), following the guidance presented in U.S. Nuclear Regulatory Commission (NRC)
publications NUREG/CR-3533 and Regulatory Guide 3.64 (NRC 1984, 1989). The rate of
emanation standard is applied to the average emanation over the entire surface of the disposal
area.

The input parameters used in the model are based on engineering experience with similar
projects, recent laboratory testing results for samples of random fill (summarized in Attachment
B of EFRI, 2012) and tailings (MWH, 2015), in addition to available data from previous work by
others, including Chen and Associates (1978, 1979, 1987), Rogers and Associates Engineering
Corporation (1988), Western Colorado Testing (1999a, 1999b), IUC (2000), and Titan (1996).

The available data from testing performed by others was summarized in Appendix A of the
Updated Tailings Cover Design report (MWH, 2011). Appendix A will be revised for the next
version of the Updated Tailings Cover Design report to include data from recent random fill and
tailings testing. The input parameters and values used in the model are outlined below.

C.2.1 Thickness of Tailings

The thickness of tailings currently deposited in Cells 2 and 3 is approximately 30 ft (914 cm),
while the anticipated tailings thickness deposited in Cells 4A and 4B will be approximately 42 ft
(1,280 cm). As documented in NRC Regulatory Guide 3.64, a tailings thickness greater than
100 to 200 cm is effectively equivalent to an infinitely thick radon source. Therefore, a thickness
of 500 cm may be used in RADON to represent an equivalent infinitely thick tailings source of
radon.

C.2.2 Radium Activity Concentration

The radium-226 activity concentration values for the tailings in the impoundments are estimated
based on material inventory data provided by Energy Fuels Resources (USA), Inc. (EFRI). A
summary of the material inventories for Cells 2 and 3 and the projected inventory for Cells 4A
and 4B is provided in Attachment C.1. The radium-226 and thorium-230 activity concentrations
are listed for each material in the inventories. These values were used to calculate a weighted
average for radium-226 and thorium-230 activity concentrations for the tailings using the volume
of material placed in Cells 2 and 3. In addition, these values were used to project radium-226
and thorium-230 activity concentrations for the materials to be placed in Cells 4A and 4B.
Calculations for radium-226 from decay of thorium-230 were also made. These calculations are
also provided in Attachment C.1. The results for Cell 3 and Cells 4A and 4B indicate the highest
radium-226 values are a result of original radium-226 and radium-226 from thorium-230 decay
at approximately 1000 years. The results are summarized below and in Table C.1.

Random Fill and Erosion Protection. The radium activity of the random fill and erosion
protection layer is assumed to be zero, based on guidance in Regulatory Guide 3.64 (NRC,
1989) which states that radium activity in the cover soils may be neglected for cover design
purposes provided the cover soils are obtained from background materials that are not
associated with ore formations or other radium-enriched materials.

Energy Fuels Resources (USA), Inc. MWH Americas, Inc.
C-3 August 2015
C.2.3 Radon Emanation Coefficient

The radon emanation coefficient used in the model for the tailings is 0.20 based on laboratory
data (Rogers & Associates, 1988) and the recommendation in NUREG-1620 (NRC, 2003) to
use a value of 0.20 for tailings if there is limited site-specific data.

The radon emanation coefficient used in the model for the cover layers is 0.35. This is the
conservative default value used in the RADON model.

C.2.4 Specific Gravity, Density and Porosity

The densities and porosities of the tailings and cover materials used in the model are based on
laboratory testing results. The values are summarized in Table C.2 and discussed in more
detail below.

Tailings 2.80 --- 96 1.5 0.45
SP = standard proctor compaction
* Estimated by applying a 25% rock correction to the topsoil

The specific gravity of the tailings was estimated as 2.80 based as the weighted average
specific gravity from laboratory tests using estimated percentages of sand, sand-slime, and
slime tailings of 10, 65, and 25 percent, respectively (MWH, 2015). The dry density of the
tailings was estimated as 96 pcf, based on laboratory tests (Chen and Associates, 1987 and
Western Colorado Testing, 1999b) and assuming the upper bound long-term density of the
tailings should be no greater than 90 percent of the average laboratory measured maximum dry
density for the tailings. The referenced reports are provided as part of Appendix A.1 of MWH
(2011). The porosity of the tailings was calculated using the estimated specific gravity and dry
density based on the following equation:

݊ൌ1െቀ ఊ೏
ீೞఊೢቁ (Eq. C.1)
where
n = porosity,
d = dry density of soil,
Gs = specific gravity of soil, and
w = unit weight of water.

The specific gravity and dry density values used in the model for the random fill layers were
estimated by laboratory tests (ATT, 2010 and UWM, 2012). The referenced reports will be

Energy Fuels Resources (USA), Inc. MWH Americas, Inc.

provided as part of Appendix A.2 of the next version of the of the Updated Tailings Cover
Design report. These reports were presented in Attachment B of EFRI (2012). The estimation
for the values used in the model is provided in Attachment C.2. The porosity values for the
layers were calculated using equation C.1. The proposed cover system has three layers of
random fill placed at different levels of compaction. The lower layer of random fill consists of a
minimum thickness of 2.5 feet of random fill that is assumed to be dumped and minimally
compacted by construction equipment to approximately 80 percent standard Proctor. The
middle layer (3.0 – 4.0 feet) of random fill will be compacted to 95 percent of standard Proctor.
In Cell 2 and parts of Cell 3, the lower layer of random fill is already placed and is approximately
3 feet. It is assumed the upper 6 inches of this fill will be part of the middle random fill layer and
can be compacted by additional passes of compactors to reach 95 percent of standard Proctor
compaction. The uppermost 3.5 feet of random fill will be placed at 85 percent of standard
Proctor compaction in order to optimize water storage and rooting characteristics for plant
growth.

The 0.5 foot erosion protection layer is assumed to be topsoil or rock mulch consisting of topsoil
material mixed with 25 percent gravel by weight. The specific gravity and density of the topsoil
was estimated to be 2.61 and 100 pcf, respectively, based on laboratory testing results for
topsoil (UWM, 2012) The specific gravity and density of the rock mulch was estimated to be
2.62 and 106 pcf, respectively, based on laboratory testing results for topsoil (UWM, 2012) and
applying a rock correction based on 25 percent gravel by weight.

C.2.5 Long-term Moisture Content

The long-term moisture content value for the tailings is assumed to be 6 percent. This is a
conservative assumption, per NRC Regulatory Guide 3.64 (NRC, 1989), which represents the
lower bound for moisture in western soils and is typically used as a default value for the long-
term water content of tailings. Use of 15 bar water contents to estimate a long-term water
content is one of the methods recommended in NRC (2003) for radon emanation modeling.

MWH collected representative samples from the on-site random fill and topsoil stockpiles for
use in estimating the long-term moisture contents for the random fill and erosion protection
cover layers. The laboratory results for the 15 bar water contents for these samples were used
to estimate long-term water contents for the random fill and erosion protection layers.

The long-term water content of the topsoil was estimated as 5.2 percent based on the measured
15 bar gravimetric water content for a topsoil sample (E1-A) which represents the average index
properties for the topsoil stockpiles (UWM, 2012). The long-term water content of the rock
mulch was estimated as 4 percent based on the addition of 25 percent gravel by weight to the
topsoil.

Based on the cover material gradations, the cover soils were bracketed into three groups, finer
grained soils, uniform graded soils, and broadly graded soils. A weighted average procedure
that accounts for the size of soil type based on the stockpile volumes was incorporated to
determine the average long-term gravimetric water content for the random fill using the
measured 15 bar water contents. The estimation of the long-term water content value for the
cover material is provided in Attachment C.2.

The average long-term moisture contents are summarized in Table C.3.

Erosion Protection (topsoil) 5.2

Tailings 6.0

C.2.6 Diffusion Coefficient

The radon diffusion coefficient used in the RADON model can either be calculated based on an
empirical relationship dependent upon porosity and the degree of saturation or input directly in
the model using values measured from laboratory testing. Although laboratory test data was
available for the tailings and the cover material (Rogers & Associates 1988), tests were
performed at porosities and water contents different than those estimated to represent long-term
conditions. Therefore, the empirical relationship presented in Rogers and Nielson (1991) was
used, resulting in the calculated values summarized in Table C.4 below.

Table C.4. Estimated Radon Diffusion Coefficients

Material
Diffusion Coefficient
(cm2/s)
Erosion Protection (rock mulch) 0.0254
Random Fill (low compaction water
storage, rooting zone) 0.0225
Random Fill (high compaction) 0.0160
Random Fill (in place, low
compaction, platform fill) 0.0260
Tailings 0.0288

C.3 MODEL RESULTS

The radon emanation modeling results show that the designed cover systems presented in
Table C.5 will reduce the rate of radon emanation to values below the limit of 20 picocuries per
square meter per second (pCi/m2-s) averaged over the entire area of the tailings impoundments,
which is the regulatory criterion (Utah Administrative Code, Rule 313-24). The RADON model
output is provided in Attachment C.3.

Total Cover Thickness 10.5 10.0 9.5

C.4 IMPACTS OF INCREASED THICKNESS OF RANDOM FILL

Radon modeling as discussed above assumed that the lower layer of random fill was placed at
80 percent of standard Proctor compaction, and had a thickness of 2.5 feet (assuming top 6
inches can be compacted to 95 percent of standard Proctor density prior to placement of
additional fill). However, there are some areas within Cells 2 and 3 which show thicknesses of
existing random fill greater than 3.0 feet. Additional modeling was performed to determine the
minimum thickness of highly compacted random fill required in order to meet regulatory criterion
to limit the radon emanation rate through the top of the cover to 20 pCi/m2-s. This modeling
indicates that for every extra foot of low-compaction random fill (80 percent standard Proctor
compaction), the highly compacted random fill layer (95 percent standard Proctor compaction)
can be reduced in thickness by approximately 0.75 feet. This trend is shown in Figure C.1. The
RADON model output is provided in Attachment C.4.

Calculation of Ra-226 Concentrations Due to Future Decay of Th-230
The RA-226 concentration at various times in the future depends on both the decay of the Ra-226 currently
present and the ingrowth from Th-230. The Ra-226 decays with a half-life of 1602 years. The ingrowth is also
a function of the Ra-226 half-life (1602 years) and the Th-230 half-life (77,000 years).

Calculation of Ra-226 Concentrations Due to Future Decay of Th-230
The RA-226 concentration at various times in the future depends on both the decay of the Ra-226 currently
present and the ingrowth from Th-230. The Ra-226 decays with a half-life of 1602 years. The ingrowth is also
a function of the Ra-226 half-life (1602 years) and the Th-230 half-life (77,000 years).
A (Ra-226) at a time t (years) = [A (Ra-226) at t=0][exp(-0.693t/1602 years)]
A (Ra-226 from decay of Th-230 at time t (years)) = [A (Th-230)][1-exp(-0.693t/1602 years)][exp(-0.693t/77,000 years)]
