Section 1. Written Comments from Sarah Fields, Uranium Watch, Program Director and
Related Oral Comments
Ms. Fields submitted the following comments in writing to the DRC on May 10, 2010. Other
commenters also provided oral comment on several of these same topics during the May 4, 2010
public meeting. For details, see written comments in Appendix A and the transcript of oral
comments in Appendix B, below.
PC-01; Archaeological Resources
Written comments from Ms. Fields (Comment 1.1, pp. 1-2) stated the following (Appendix
A, pp. 1–2):“1. WHITE MESA ARCHAEOLOGICAL RESOURCES
1.1. The construction of Cell 4B will impact a number of Archaeological Resources at the
Mill site and in the White Mesa Archaeological District. White Mesa is in an area adjacent
to and in the vicinity of extensive tribal holdings and an area rich in archaeological
resources, which have been designated as significant and deserving of preservation. Many
Archaeological Resources on White Mesa have been found eligible for the National
Register, including resources that will be or have been impacted by activities associated
with the proposed license amendment.
The Licensee and the Utah Division of Radiation Control (DRC) have not complied with
the requirements of License Condition 9.7, which states, in pertinent part:
'All disturbances associated with the proposed development will be completed in
compliance with the National Historic Preservation Act (as amended) and its
implementing regulations, and the Archaeological Resources Protection Act (as
amended) and its implementing regulations.'
Compliance with the National Historic Preservation Act includes compliance with
Section 106. The Safety Evaluation Report (SER) fails to discuss how the Applicant
fulfilled its responsibilities under the National Historic Preservation Act (as amended)
and its implementing regulations, and the Archaeological Resources Protection Act (as
amended) and its implementing regulations.
A contractor to the licensee has commenced excavation of the Archaeological Resources
at the Mill, with approval of the DRC. However, excavation has commenced without the
any Section 106 consultation. The excavation of the valuable Archaeological Resource on
White Mesa has taken place without informing and consulting with nearby tribal
governments and tribal Historic Preservation Officers and without an opportunity for
public comment.
Further, the Licensee commenced activities that have impacts on the Archaeological
Resources and are the subject of License Condition 9.7 requirements prior to this
comment period and prior to the issuance of the license amendment and final
environmental evaluation.
All activities that impact Archaeological Resources at the Mill should cease until DRC
initiates and completes a Section 106 consultation process, including consultation with
affected tribal governments or appropriate tribal representatives. The DRC should not
issue the license amendment without consulting with the Ute, Navajo, and other regional
Public Participation Summary

tribal Historic Preservation Officers regarding the destruction of irreplaceable historic
resources.
Further, the SER must include a discussion of how the Applicant has complied with the
provisions of License Condition 9.7.”
In oral comments, Ms. Fields stated that archaeological excavation is currently taking place at
over ten archaeological sites and reported that most of the archaeological sites on White Mesa are
ancient pit houses (see Appendix B, p. 16). Ms. Fields reported that at the initial construction of
the White Mesa mill and facility, ancient artifacts were removed and placed in the University of
Utah or the Edges of the Cedars (museum). Ms. Fields complained, however, that none of these
artifacts have been exhibited, no studies have been conducted, and no results presented, and
asserted that although artifacts have been and will be removed, the sites have been and will be
destroyed by mill construction and expansion.
In oral comments, another person (Toni Turk, Mayor of Blanding) indicated that all of the
artifacts that are recovered and recovered according to archeological procedure are made
available for further research at the Edge of the Cedars Museum (see Appendix B, p. 12). He also
indicated that the [Blanding] Rotary Club recently received a detailed presentation of recovery of
archaeological knowledge that Denison Mines has funded (see Topic PC-09;
Communication/Consultation with White Mesa Ute Tribe, below, for further discussion).
Division Response: Substantive Comment.
The Utah Radiation Control Act contains no requirement that mandates that the DRC address the
evaluation or preservation of archaeological resources. However, the License Condition 9.7 does
address archaeological resources.
The Executive Secretary disagrees with the comment that under License Condition 9.7 the Utah
DRC must undertake Section 106 consultations pursuant to the National Historic Preservation
Act, 16 U.S.C. § 470f 3. By its terms, Section 106 applies to actions by “any Federal agency”
having jurisdiction over a proposed “Federal or federally assisted undertaking”. As the
“undertaking” at issue here is licensing of disposal Cell 4B by a State of Utah agency, Section
106 consultation is inapplicable. Nonetheless, the DRC has required the licensee to take all
necessary and appropriate steps to identify and preserve cultural resources that may be
unavoidably disturbed during the construction of Cell 4B.
Consistent with License Condition 9.7, the licensee arranged for archaeological cultural research
studies of the Cell 4B area. As part of these studies, Abajo Archaeology developed “A Research
Design for Archaeological Data Recovery on Ten Sites in the White Mesa Mill Cell 4B Project
Area, San Juan County, Utah” (hereafter “Abajo Research Design”). The Abajo Research Design
describes archaeological test excavations of ten sites in the Cell 4B project area; provides a
research design for archaeological data recovery at those sites; and commits to the preservation of
artifacts from the site.

3 Condition 9.7 in DUSA’s Utah license is a remnant from its federal U.S. NRC mill license.
When the U.S. NRC delegated licensing of uranium mills to Utah in August 2004, Condition 9.7,
as drafted by the U.S. NRC, was imported into the Denison Mine’s Utah license.
Public Participation Summary
June 14, 2010
Page 8 of 8
The Executive Secretary sent the Abajo Research Design to the Utah State Historic Preservation
Office, who responded: “We concur that the approach outlined in the research design prepared by
Abajo Archaeology will mitigate adverse effects resulting from this project” (see Letter from Lori
Hunsaker, Deputy State Historic Preservation Officer - Archaeology to Dane Finerfrock,
Director, Division of Radiation Control, dated December 17, 2009).
To fulfill the requirements of License Condition 9.7, DUSA:
Is following the Abajo Research Design prior to beginning construction in any affected
cultural resource area identified in that document;
As described in the Abajo Research Design, will require “Abajo Archaeology to submit
all artifacts and associated files from the project to the Edge of the Cedars Museum. All
artifacts will be housed in archival materials, including artifact bags and boxes as
stipulated by the Edge of the Cedars.” Abajo Research Design at p.94.
When excavation and preservation of cultural resources are complete, will submit a final
archaeology report to the Executive Secretary outlining the steps it took to comply with
the Abajo Research Design. It is anticipated that this report will be available by the end
of July 2011.
See Letter from DUSA to the Executive Secretary, dated June 8, 2010 (DUSA 2010).
Various archaeological documents relating to the construction of Cell 4B are accessible to the
public on the DRC website. In addition, the public may request paper copies of these documents
and/or inspect files at the DRC, which contain current and historic archaeological documents
relating to the White Mesa Mill site.
Copies of DUSA, DRC, and SHPO correspondence, plans, and reports documenting the ongoing
archaeological investigations and recovery work are posted on the DRC website at
http://www.radiationcontrol.utah.gov/Uranium_Mills/IUC/cell4b/cultural_resources4b.htm.
PC-02; License Condition 9.7
A written comment from Ms. Fields (Comment 1.2) stated the following (Appendix A, p. 2):
“1.2 LICENSE CONDITION 9.7
The DRC is not proposing any changes to License Condition 9.7, which pertains to the
cultural resources at the Mill. License Condition 9.7 refers to a Memorandum of
Agreement (MOU) between the Utah State Historical Preservation Officer (SHAPO), the
Advisory Council on Historic Preservation (ACHP) the Nuclear Regulatory Commission
(NRC), and Energy Fuels Nuclear, Inc. (a former Mill owner/licensee). The MOU was
ratified on August 20, 1979, and amended on May 3, 1983. The MOU should be amended
or replaced, since it does not reflect the current situation at the Mill.”
In oral comment, Ms. Fields asserted the LC 9.7 should be stricken from the license and later that
the license condition should be reviewed and brought up to date (see Appendix B, p. 18).

Division Response: Non-substantive Comment.
DRC agrees there may be opportunities for improvement to the wording found in LC 9.7. License
Condition 9.7 may be updated as part of the ongoing review of the license renewal application.
PC-03; Licensee Reporting Responsibilities
A written comment from Ms. Fields (Comment 2.1) stated the following (Appendix A, pp. 2–3):
“2. SAFETY EVALUATION REPORT (SER)
2.1 LICENSEE REPORTING RESPONSIBILITIES (SER, PAGE 21)
The DRC should make the effluent monitoring reports, Semi-Annual Effluent Reports and
Quarterly Groundwater Monitoring Reports and any additional effluent monitoring
information submitted by the licensee pursuant to License Condition 11.2 available on the
DRC website in a timely manner.”
Ms. Fields requested in oral comments that the DRC make the effluent monitoring reports and
any additional effluent monitoring information submitted by the licensee pursuant to LC 11.2
available on the DRC’s website (see Appendix B, p. 18).
Division Response: Non-substantive Comment.
The DRC is currently undergoing an initiative to make documents more readily and more rapidly
available to the public on the DRC’s website. In the interim, interested parties can request
information that is not currently available on the DRC’s website through the existing Utah
Government Records Access and Management Act (GRAMA) records request processes in Utah
Code Annotated Title 63G, Chapter 2 or inspect the files at the DRC.
PC-04; Long-Term Impacts
A written comment from Ms. Fields (Comment 2.3)4 stated the following (Appendix A, pp. 3–4):
“2.3 LONG TERM IMPACTS
UCA R313-24-3D: Environmental Analysis - Long Term Impacts, Safety Evaluation,
states that, pursuant to UAC R313-24-3, a major license amendment should include
"consideration of the long-term impacts." The SER discussion addresses long-term
impacts. However, the SER and the UCA section do not define long-term and leave the
issue of long-term containment of the mill tailings and their associated emissions to be
addressed in a future Reclamation Plan. Under current federal regulation (40 C.F.R.
Sec. 192.32(B)(1)(i)5), consideration of the technical requirements for long-term
containment of the tailings is limited to "one thousand years, to the extent reasonably
achievable, and, in any case, for at least 200 years." The SER (page 30) states that Cell
4B has been designed to provide "reasonable assurance that radiological hazards will be
suitably controlled for 1,000 years, to the extent reasonably achievable, and in any case
for at lease 200 years.

4 sic. Ms. Fields May 10, 2010 submittal did not contain any comment numbered 2.2.

“So, we have "reasonable assurance" to the extent that suitable control is "reasonably
achievable." What does this vague language mean over the long-term? The public, the
licensee, and the DRC do not really know.
“The tailings will remain on White Mesa in perpetuity, that is, forever. Therefore impacts
from 200 to 1,000 years are short-term impacts, not long-term impacts, given the time
that the tailings will continue to release radon and will be a radioactive and hazardous
material requiring physical and regulatory control for as long as there are individuals
and entities capable of exercising that control.
“Eventually the liners will break down, eventually the tailings cover will erode, and
eventually the tailings and the associated radioactive and non-radioactive contaminants
will disperse into the air, water, and soils.
“Any evaluation of the long-term impacts of the proposed licensing action must address
the potential impacts of the dispersion of the tailings from natural forces over the
thousands and millions of years that the tailings will remain in place.”
___________________________
1 40 CFR Sec. 192.32(B)(1)(i).
(1) Disposal areas shall each comply with the closure performance standard in Sec. 264.111 of this chapter
with respect to nonradiological hazards and shall be designed to provide reasonable assurance of control of
radiological hazards to (i) Be effective for one thousand years, to the extent reasonably achievable, and, in
any case, for at least 200 years, and, (ii) Limit releases of radon-222 from uranium byproduct materials to
the atmosphere so as to not exceed an average \2\ release rate of 20 picocuries per square meter per second
(pCi/m2s).
\2\ This average shall apply to the entire surface of each disposal area over periods of at least one year, but
short compared to 100 years. Radon will come from both uranium byproduct materials and from covering
materials. Radon emissions from covering materials should be estimated as part of developing a closure plan
for each site. The standard, however, applies only to emissions from uranium byproduct materials to the
atmosphere.”
In oral comments, Ms. Fields asserted that the DRC is required to prepare a Safety Evaluation
Report (SER) for a major license amendment under the Atomic Energy Act (see Appendix B, pp.
21-22). The person also observed that the Atomic Energy Act has specific requirements for
agreement states and that the State of Utah is an agreement state, through which the federal
government has given the State of Utah the responsibility for regulating uranium mills within
Utah. The commenter observed that SER states that Cell 4B has been designed to provide
reasonable assurance that radiological hazards will be suitably controlled for 1,000 years to the
extent reasonably achievable, and in any case, for at least 200 years. The person the expressed the
common belief that although the tailings will remain in perpetuity, the containment features and
system will eventually degrade to allow radioactive and non-radioactive contaminants to be
released into the environment. This person then asserted that DRC should consider the
performance of the tailings impoundments for up to 100,000 years.
Division Response: Substantive Comment.
The DRC reviews license applications for tailings management and tailings reclamation facilities
in accordance with existing established regulations and rules, including UAC R313-24, as
mentioned in the comment. The set of standards established for stabilization of reclaimed tailings
Public Participation Summary

Page 11 of 11
management cells that are applicable to the DUSA White Mesa Mill Facility is prescribed by the
NRC in 10 CFR 40, including Criterion 6(1), of those regulations:
“In disposing of waste byproduct material, licensees shall place an earthen cover (or
approved alternative) over tailings or wastes at the end of milling operations and shall
close the waste disposal area in accordance with a design which provides reasonable
assurance of control of radiological hazards to (i) be effective for 1,000 years, to the
extent reasonably achievable, and, in any case, for at least 200 years, and (ii) limit
releases of radon-222 from uranium byproduct materials, and radon-220 from thorium
byproduct materials, to the atmosphere so as not to exceed an average release rate of 20
picocuries per square meter per second (pCi/m2s) to the extent practicable throughout
the effective design life determined pursuant to (1)(i) of this Criterion. In computing
required tailings cover thicknesses, moisture in soils in excess of amounts found normally
in similar soils in similar circumstances may not be considered. Direct gamma exposure
from the tailings or wastes should be reduced to background levels. The effects of any
thin synthetic layer may not be taken into account in determining the calculated radon
exhalation level. If non-soil materials are proposed as cover materials, it must be
demonstrated that these materials will not crack or degrade by differential settlement,
weathering, or other mechanism, over long-term intervals.”
The regulatory basis for the NRC environmental standards was provided by the Environmental
Protection Agency (EPA) in documents published in 40 CFR Part 192. The NRC adopted these
environmental standards in the Federal Register in 1983. In the Federal Register Notice
describing the NRC basis for adopting these standards under 40 CFR Part 192 (“Environmental
Standards for Uranium and Thorium Mill Tailings at Licensed Commercial Processing Sites,”
Proposed Rule, published in Federal Register 48(84):19584-19603, April 29, 1983), EPA notes
(ibid., p. 19,597) that the selected design alternative (Alternative D – stabilization to be designed
to be effective for 1,000 years, to the extent practicable, or, in any case [designed to be effective]
for at least 200 years) “will provide stability against erosion and casual intrusion for misuse for
much longer than 1,000 years” except for “those few piles that are susceptible to flood damage,”
which “would be protected for at least 200 years, and are unlikely to suffer real damage for much
longer.” EPA also identifies that casual intrusion by man is limited by thick and hard-to-penetrate
covers, and that the main design issue is protection against natural forces (wind and surface water
erosion, and of the possibility of flood damage). They indicate that wind and surface-water
erosion are well-understood and predictable, and are easily inhibited through the use of rock or, in
some cases, vegetative surface stabilization.
When reviewing documents submitted by Licensees that relate to construction, operations, and
reclamation activities that are proposed to be conducted at the White Mesa Mill Facility with
respect to the potential for these activities to cause long-term environmental impacts, the DRC
must consider and has considered requirements contained in the above set of NRC standards.
Interested parties, should they choose to do so, have the option of requesting that changes to
existing rules and statutes be considered and implemented. Such requests would need to be
pursued through established formal rule-making requests to the Utah Radiation Control Board
and/or to the NRC, or by a State or Federal legislative processes.

PC-05; Permanent Isolation without Ongoing Maintenance
A written comment from Ms. Fields (Comment 2.4) stated the following (Appendix A, p.4):
“2.4 PERMANENT ISOLATION WITHOUT ONGOING MAINTENANCE (SER, PAGE
24)
10 CFR Part 40, Appendix A, Criterion 1, states that tailings should be disposed of in a
manner that no active maintenance is required to preserve conditions of the site.
“There is no doubt that over the years, active maintenance will be required to preserve
conditions of the site. The Department of Energy (DOE) has already discovered that
active maintenance is required at some of the uranium mill sites that have been reclaimed
and that DOE have responsibility for, due to erosion. The DOE is actively looking at
different cover and tailings design systems because of the problems they have
encountered at these sites.
“No matter what the design is, eventually the cover, tailings, and White Mesa itself, will
erode, as demonstrated by the geological landscape in the region. Any claim to continued
long-term isolation of the tailings--without active maintenance--via a man-made design is
not supportable.
“The DRC should consult with the DOE and the Nuclear Regulatory Commission and
take into consideration recent studies and data regarding the effectiveness of tailings
system designs and materials to update the final cover design and materials requirements
in order to achieve the maximum long-term isolation of the tailings with minimal
maintenance. The DRC should not mislead the public and licensee into thinking that
isolation of the tailings for 1,000 and for the long-term future can take place without
active maintenance.”
Ms. Fields also expressed doubt in oral comments presented at the Public Hearing that tailings
could be isolated without relying on ongoing maintenance and recommended that DRC should
consult with NRC and Department of Energy to identify realistic long-term maintenance
scenarios and to take advantage of new data and information that is being generated (see
Appendix B, pp.23-24).
Division Response: Substantive Comment.
We agree with the comment that the NRC rules mandate uranium mill tailings facilities be
designed and constructed such that no ongoing maintenance is required (10 CFR 40, Appendix A,
Criterion 1). As mentioned above, the 200 to 1000-year engineering design / stability standard is
found in the NRC rules (10 CFR 40, Appendix A, Criterion 6). Both of these requirements are
adopted in the corresponding Utah regulations (see UAC R313-24-4). Upon closure of the
facility, and completion of certain other requirements, the site will be transferred to the DOE who
will then take control and possession of the tailings site (see 10 CFR 40.28). Under this
ownership, the federal government will provide any long-term maintenance required.
The DUSA reclamation plan is currently under review by the DRC as a part of the license
renewal process. During this review, the DRC will consider available information on the
performance of other completed final cover systems, including covers constructed at DOE
reclamation sites (e.g., U.S. DOE Uranium Mill Tailings Reclamation Act Project sites and other
Public Participation Summary

sites), and published NRC guidance documents relating to the final capping and closure of
uranium mill tailings impoundments, uranium tailings piles, etc…, for long-term stabilization,
including, but not limited to, NUREG-1623 (NRC 2002), and documents referenced therein, and
other published technical documents and reports that contain updated information regarding the
design and expected longer-term performance effectiveness of final closure cover systems.
See also the response regarding established design requirements and standards provided in regard
to the previous comment (Topic PC-04).
PC-06: Impacts of Dewatering of the Tailings Cell
A written comment from Ms. Fields (Comment 2.5) stated the following (Appendix A, pp. 4–5):
“2.5 IMPACTS OF DEWATERING OF THE TAILINGS CELL (SER, PAGES 25–26)
The discussion of the permanent isolation without ongoing maintenance (10 CFR Part
40, Appendix A, Criterion 1) and the Reclamation Plan refer to the dewatering of the
tailings cell after the operational life of the cell. However, there is minimal discussion
about two of the primary problems encountered at uranium mills once operation has
ceased and cell dewatering commences. Once dewatering commences, the result is an
increase in the release of radon from the cell and an increase in windblown tailings. The
SER mentions the possibility of the use of "platform fill," but provides little information
and analysis of the use of fill or other means to minimize the emission of radon,
hazardous and radioactive particulates to the atmosphere and the environment.
“The SER should discuss in more detail the impacts of cell dewatering on the emission of
radon and other gases and hazardous and radioactive particulates and how these
impacts will be mitigated during the estimated 5.5 years between the cessation of cell
operation and the placement of an interim and final cover.”
In addition to written comments dealing with release from the facility during dewater following
cessation of milling operations, one person (Bradley Angel) provided an oral comment expressing
concern for the potential windblown tailings during periods of high winds (see Appendix B, p.
26).
Division Response: Substantive Comment.
The applicant (DUSA) is required, on a yearly basis, to monitor for radon emissions from existing
tailings cells. Applicable EPA regulations are specified in 40 CFR Part 61, Subpart W, National
Emissions Standards for Radon Emissions from Operating Mill Tailings, with technical
procedures in Appendix B. These standards are a subset of the National Emission Standards for
Hazardous Air Pollutants (NESHAPs). According to subsection 61.252, Standard, (a) radon-222
emissions to ambient air from an existing uranium mill tailing pile shall not exceed an average of
20 picoCuries per square meter per second (20 pCi/m2-s) for each pile or region (emphasis
added). The term “existing” tailings pile is defined as a cell that was in existence on or before
December 15, 1989 [see 40 CFR 61.251(d)]. Cell 4B does not meet this requirement.
It is also important to note EPA’s intent in 40 CFR 61 Subpart W, wherein the 20 pCi/m2/sec air
quality standard was applied to “existing” tailings cells, and new design, construction, and
operation standards applied to “new” tailings cells (built after December 15, 1989). For the “new”
Public Participation Summary

tailings cells, the operator was required to design, construct and operate the cells under one of two
practices:
1) conduct phased tailings disposal in a cell area that is less than 40 acres, and have no more
than two tailings impoundments in operation at any one time (including “existing”
impoundments), or
2) continuous disposal of tailings that are dewatered and immediately disposed of with no
more than 10 acres uncovered at any time, in accordance with the requirements of 40
CFR 192.32(a), as determined by the NRC.
In the case of DUSA, the company has elected to operate Cells 4A and 4B under Option 1, above.
With regard to NESHAPs, Subsection 61.253, Determining Compliance, states that, “Compliance
with the emission standard in this subpart shall be determined annually through the use of Method
115 of Appendix B.” This monitoring is performed by DUSA on (ibid., Section 2.1.2): 1) water
saturated tailings (or beaches), and 2) dry top surface areas.
The results of the annual radon measurements are reviewed and facility compliance status is
determined by the Utah Division of Air Quality (DAQ). While informal review of this data is
done by DRC staff, the DRC does not have authority to enforce DAQ / NESHAPs requirements.
However, in the event that DAQ determined there to be non-compliance with NESHAPs
requirements, DUSA could pursue more than one alternative to control radon emissions,
including, but not limited to: construction of a temporary cover soil, or the final radon barrier.
Certainly, any radon barrier construction is subject to the DRC regulations, and to the
requirements found in License Condition 9.11 and the approved Reclamation Plan. During such
construction, DRC staff would be involved in construction inspections, and review of any As-
Built or Closure Report.
Historic DUSA radon emission rate data collected from tailings management Cells 2 and 3 at the
White Mesa Facility could be considered representative of expected future radon emission rates
from proposed Cell 4B. The average radon flux measured for the covered Cell 2 area during 2009
was 13.7 pCi/m2 per second. This assumption is reasonable, given the similarity of tailings
materials and operations. The areas (surface size) measured atop Cell 3 will be variable during
tailings management operations as a result of operations and therefore measured radon emission
rates may vary, depending on the time of measurement. Radon emission rates obtained during
2007, 2008, and 2009, have been reported by DUSA for both exposed (“beach”) and soil-covered
tailings materials in “existing” Cell 2 and 3 (at the top of the interim cover soil layer placed over
the tailings). Reported average radon emission rates for the soil-cover areas measured during the
2007 to 2009 period are 13.9, 5.5, and 4.5 pCi/m2 per second, respectively. Average emission
rates reported for the beach areas measured in 2007, 2008, and 2009, are 6.7, 12.2, and 19.1
pCi/m2 per second. The geometric mean radon emission rate for the 2007-2009 monitoring period
was 9.65 pCi/m2 per second for the “soil cover” areas, and 7.01 pCi/m2 per second for the beach
areas (see the annual NESHAPs Radon Flux Measurement Program reports prepared by Tellco
Environmental. All of these DUSA measured concentrations are compliant with the NESHAPs
standard (20 pCi/m2/sec). An example Annual NESHAPs report is the National Emission
Standards for Hazardous Air Pollutants 2009 Radon Flux Measurement Program White Mesa
Millsite Report, prepared by Tellco Environmental, submitted to DUSA on February 17, 2010
(Tellco Environmental 2010).

On the question of radioactive particulates, the site is monitored on a continuous basis at five (5)
monitoring stations around the site. These monitoring stations monitor all emissions released
from the site including the tailings impoundments.
Radioactive particulate monitoring results can be found in Semi-Annual Effluent Monitoring
Reports and in the annual NESHAPs Radon Flux Measurement Program reports). Radon
monitoring at the restricted area (RA) boundary was discontinued in 1995, after NRC approval
(see August 29, 2009 DUSA report, p. 5). In lieu of actual radon measurements at the RA
boundary, the NRC allowed DUSA to determine radon concentrations in air with a calculation
method (ibid.). This same approach is also allowed under Part 15 of the Utah Radiation Control
Regulations [see UAC R313-15-302(2)(a)].
It is also worth noting that the direct measurement of the radon flux from uranium tailings is not
required by current guidance from the Nuclear Regulatory Commission (NRC). NRC
requirements are presented in Regulatory Guide 4.14, Revision 1, Radiological Effluent and
Environmental Monitoring at Uranium Mills, April 25, 1980 (NRC 1980) and NUREG-1620
Standard Review Plan for the Review of a Reclamation Plan for Mill Tailings Sites Under Title II
of the Uranium Mill Tailings Radiation Control Act (NRC 2000). The regulatory guide calls for
pre-operational radon flux measurements to establish background flux, but does not require
operational flux measurements in this guide. Instead, measurements are required at the end of the
disposal cell’s operational life, as it is prepared for closure, and after the radon barrier is installed.
PC-07; Off Site Measuring Devices
A written comment from Ms. Fields (Comment 2.6) stated the following (Appendix A, p. 5):
“2.6 OFF SITE MEASURING DEVICES
The February 12, 2010, letter to Dave Frydenlund, DUSA, from Senes Consultants Ltd.,
states (page 2): ‘Due to the inaccuracy of the radon measurement devices the mill is not
required to sample for environmental radon under its license.
The Application for Cell 4B and the SER fail to provide supportive documentation
regarding various types of radon measuring devices and their supposed “inaccuracy” to
justify the failure to measure environmental radon from Cell 4 B and other radon sources
at the Mill. This would include on- and off-site monitoring of radon.
The SER should include a full justification, with supporting documentation, of the on-
and off-site radionuclide monitoring programs, including monitoring of radon. If DUSA
is not required to sample for environmental radon and other radioactive releases on- and
off-site, the public must know why and have supporting technical bases.”
Division Response: Substantive Comment.
Radon effluent from the White Mesa Mill Site is calculated and not directly measured. This is in
compliance with R313-15-302(2)(a), and was authorized by the NRC. The explanation is
presented in the Semi-Annual Effluent Monitoring Reports as follows (e.g., see DUSA 2009, p.
5):
“Due to unavailability monitoring equipment to detect the new 10 CFR 20 standard, and
with the approval of the NRC, Radon-222 monitoring at BHV stations was discontinued

in 1995. Instead, Denison demonstrates compliance with these limits and the
requirements of R313-15-301 by calculation, authorized by the NRC and as contemplated
by R313-15-302(2)(a)......This calculation is performed by use of the MILDOS code for
estimating environmental radiation doses for uranium recovery operations (Strenge and
Bender 1981) and more recently in 2003 by use of the updated MILDOS AREA code
(Argonne 1998). The analysis under both the MILDOS and MILDOS AREA codes
assumes the Mill to be processing high grade Arizona Strip ores at full capacity, and
calculates the concentrations of radioactive dust and radon at individual receptor
locations around the Mill.”
The MILDOS and MILDOS AREA codes calculate the combined Total Effective Dose
Equivalent (“TEDE”) from all relevant pathways, including both air particulate and radon, at a
number of locations including the nearest residence (the individual likely to receive the highest
dose from the licensed operation), approximately 1.6 miles north of the Mill. These calculations
reveal projected doses to the individual likely to receive the highest dose from the licensed
operations to be well below the 100 mrem regulatory limit in R313-15-301(1)(a) for all pathways,
including air particulate and radon as set out in R313-15-101(4). MILDOS AREA modeling was
recently conducted in support of the Mill’s 2007 License Renewal Application, utilizing the
MILDOS-AREA code (Version 2.20 ), to estimate the dose commitments at various receptor
locations for processing of Colorado Plateau ore (0.25% U3O8 and 1.5% V205) and Arizona Strip
ore (0.637% U3O8). The process rate was assumed to be at full capacity of 730,000 tons per year
(an average of 2,000 tons per day) with an average uranium recovery yield of 94%. That
modeling showed a TEDE of 2 mrem per year at the nearest resident (3 mrem per year at the
nearest potential residence, being the location of BHV-1 at the northern property boundary of the
Mill site), which included the dose from all radionuclide sources, including radon. The modeled
dose from radon itself was therefore a fraction of TEDE and well within regulatory limits.”
The January 1 through June 30, 2009 results can be found in the DUSA Semi-Annual Effluent
Monitoring Report dated August 29, 2009 (DUSA 2009).
PC-08; Effluent Control During Operations
A written comment from Ms. Fields stated the following (Appendix A, p. 5):
"2.7 EFFLUENT CONTROL DURING OPERATIONS (SER, PAGES 59 - 60)
The SER discusses compliance with 10 C.F.R. 40, Appendix A, Criterion 8, with respect
radioactive effluents from the mill and tailings impoundment. Criterion 8 includes the
requirement:
“‘Milling operations producing or involving thorium byproduct material must be
conducted in such a manner as to provide reasonable assurance that the annual dose
equivalent does not exceed 25 millirems to the whole body, 75 millirems to the thyroid,
and 25 millirems to any other organ of any member of the public as a result of exposures
to the planned discharge of radioactive materials, radon-220 and its daughters excepted,
to the general environment.'
“The SER fails to discuss how compliance with the above requirement for exposures to
the public will be measured and compliance will be assured with respect the release of
the discharge of radioactive materials from Cell 4B and other sources at the mill during
the operation of the tailings cell.
Public Participation Summary
June 14, 2010
Page 17 of 17
“The SER should explain exactly how the Applicant will demonstrate compliance with
Criterion 8 with respect the emission from Cell 4B.”
Division Response: Non-substantive Comment.
The cited requirement on radioactive effluents from the mill and tailings impoundment applies to
facilities that produce thorium metal or beneficiate thorium ores, and as a result dispose of
thorium byproduct materials. Because the White Mesa Uranium Mill Facility does not produce
thorium, the cited requirements do not apply. No comparable requirement exists that applies to
uranium milling or uranium byproduct disposal facilities.
PC-09; Communication/Consultation with White Mesa Ute Tribe
One person (Toni Turk) reported orally that the [Blanding] Rotary Club recently received a
detailed presentation of recovery of archaeological knowledge that Denison Mines has funded.
The presentation reported that the database of understanding of the cultures that have lived here
anciently has been significantly expanded and that those artifacts that are recovered according to
archaeological procedure are made available for further research at the Edge of the Cedars
Museum.
One person (Ms. Fields) orally expressed a belief that the failure of the Division of Radiation
Control and the failure of the Utah Historical Society to consult with the White Mesa Ute and the
Ute Mountain tribal governments and the Navajo tribal historic preservation [under Section 106
of the National Historic Preservation Act] is unacceptable and that the Division of Radiation
Control must consult with these entities before they approve the proposed license amendment
(see Appendix B, pp. 17-18).
In written comments (Appendix A, p. 2), Ms. Fields asserted that excavation of valuable
archaeological resources on White Mesa has taken place without informing and consulting with
nearby tribal governments and tribal Historic Preservation Officers and without an opportunity
for public comment.
One person (Toni Turk) stated in oral comments that one person who has worked very closely
with the White Mesa Utes “is very computer literate and is able to receive and disperse all
communications that pertain to that community and, to [his] knowledge, [she] does that…” (see
Appendix B, pp. 11-12).
Division Response: Substantive Comment.
DUSA, SHPO, and DRC have addressed the issues involving preservation of archaeological
resources as described in DRC’s response to Topic PC-01, above.
PC-10; Compliance with Other Federal and State Regulations
A written comment from Ms. Fields (Comment 2.8) stated the following (Appendix A, pp. 5-6):
“2.8 COMPLIANCE WITH OTHER FEDERAL AND STATE REQUIREMENTS
The SER does not discuss required compliance with other state and federal regulations
prior to the commencement of construction of Cell 4 B. This would include compliance
with the requirements of 40 C.F.R. Part 61, Subpart A. Section 61.07 requires that DUSA
Public Participation Summary
June 14, 2010
Page 18 of 18
submit an application to the Utah Division of Air Quality (DAQ) for Cell 4B as a new 40
C.F.R. Part 61, Subpart W regulated source and receive an approval from the DAQ,
pursuant to Section 61.08. Recently, DUSA was issued a Notice of Violation by the
Environmental Protection Agency for failure to comply with the Subpart A
application/approval process for the Arizona 1 uranium mine. Therefore, the DRC should
remind DUSA of their Part 61 responsibilities. Additionally, DUSA may be required to
amend their air quality permit for the non-radioactive emissions from the uranium mill.
The White Mesa license should contain a condition that states that DUSA must comply
with all applicable federal and state regulations and statutes and a license condition that
states that DUSA cannot commence construction of Cell 4B until DUSA receives the
required approval as a new 40 C.F.R. Subpart W regulated source from the DAQ.”
In oral comments, one person (Bradley Angel) claimed that the State of Utah has an obligation to
comply with Federal requirements related to the preservation of ancient, potentially ceremonial
and/or culturally significant site since it is making consideration under federal rules. He sated that
the State is delegated authority from the federal government to administer this regulatory program
(see Appendix B, pp. 9-10).
Division Response: Non-substantive Comment.
The regulations cited deal with the EPA NESHAPs program. With respect to air quality issues,
the DRC operates within the bounds prescribed by the Utah Radiation Control Act (Utah Code
Annotated [UCA] Title 19 Chapter 3) and rules promulgated thereunder. The DRC is not
authorized to enforce issues that fall into the domain of the Utah Division of Air Quality (DAQ).
Rather DAQ bears this responsibility.
Nonetheless, in a submittal dated April 13, 2010, DUSA made application to DAQ for an
amendment to their existing Air Quality Order for the construction of Cell 4B. For convenience
of the public, a link has been created on the following DRC webpage to direct a reader to this
application: http://www.radiationcontrol.utah.gov/Uranium_Mills/index.htm.

Section 2. Oral Only Comments from Public Hearing Held May 4, 2010 in Blanding, Utah
At the public hearing held in Blanding, Utah on May 4, 2010 several persons made oral
comments. These commenters and the topics of their comments are summarized in Table 1. A
copy of the transcript from the meeting is found in Appendix B, below. Rather than restating each
oral comment verbatim, the DRC has summarized these comments with a concise statement that
draws all similar comments together.
PC-11; Notice of Public Hearing
Three persons (Bradley Angel, Toni Turk, and Joe Lyman) commented about the process by
which DRC provides notification of public hearing.
One person (Bradley Angel) complained that unless affirmatively signing up for the DRCs
ListServ web page, a person does not received notices. He also asserted that many White Basin
Ute community members do not have regular access to the internet and asserted that the people
most affected by the proposed licensing action are not informed (see Appendix B, p. 8).
Another person (Joe Lyman) stated the he “. . . stumbled into finding out this hearing was
happening . . . .” and he had sent out an e-mail to a few people, hoping they would attend (see
Appendix B, p. 19).
As described above (under PC-09, Communication/Consultation with White Mesa Ute Tribe),
Toni Turk offered a different opinion, stating that at least one person has worked very closely
with the White Mesa Utes and is very computer literate, as well as able to receive and disperse all
communications that pertain to that community.
Division Response: Non-substantive Comment.
DRC followed applicable administrative requirements contained in Utah Administrative Code
Rule 313-17-2 providing public notice of the Public Hearing held in Blanding, Utah on May 4,
2010. The Public Notice was published in the Deseret Morning News and the Salt Lake Tribune
(April 7, 2010 Original Notice; April 9, 2010 Addendum Notice), and the Blue Mountain
Panorama, a Blanding paper (April 7, 2010 Original Notice; April 14, 2010 Addendum Notice).
PC-12; Release of Yellowcake from Stacks
One person (Bradley Angel) asked when was the last time DRC assessed the release of
yellowcake (U3O8) from stacks at the White Mesa mill and when were the people of White Mesa
last informed about such releases (see Appendix B, p. 8).
Division Response: Substantive Comment.
DUSA conducts periodic monitoring of stack emissions at the White Mesa Facility in accordance
with guidance provided in NRC Regulatory Guide 4.14, Rev. 1 (NRC 1980). Emissions from air
emission sources (stacks) that involve processes that include effluent control equipment with
subsequent emission (i.e., the north yellowcake dryer and yellow cake dryer baghouse) are the
subject of quarterly and/or semi-annual monitoring by DUSA. Stack air samples are analyzed for
natural uranium, radium 226, thorium 230, and lead 210.
Public Participation Summary
June 14, 2010
Page 20 of 20
Stack monitoring results are reported in the Semi-Annual Effluent Monitoring Reports. These
reports are available to the public upon request under GRAMA. A form for this purpose is
provided on the DRC website at: http://www.radiationcontrol.utah.gov/forms.htm.
PC-13; Social Justice
One person (Bradley Angel) believed that the state is violating the United States Civil Rights Act,
Title VI because “[a]s a recipient of federal funding, you are prohibited from taking any actions
that would have discriminatory or disproportionate impact on low income people of color, like
the White Mesa Ute people…” (see Appendix B, p. 10).
Division Response: Non-substantive Comment.
The Executive Secretary disagrees with the commenter’s opinion that DRC’s actions are
discriminatory.
PC-14; Rules Should Be Changed
One person (Chris Webb) reported his experience during eight years serving as a member of the
Utah State Drinking Water Board (see Appendix B, p. 28-29). He told that people frequently
argue that the rules need to change and need to be tougher because undesirable things (what ifs)
might occur. This commenter stated, however, that the proposal being considered today should be
judged on the rules that are in place today and encouraged the state to judge proposal by today's
rules, not on hopes for future changes in the rules.
Division Response: Non-substantive Comment.
Comment noted. No response required.
PC-15; Economic Benefit and Employment Provided by Mill Operations
Two persons mentioned the large economic effect the White Mesa uranium mill has on the
surrounding area. One person (Toni Turk) stated that the uranium mill is a major employer of the
White Mesa Ute community and works in collaboration with Denison Mines for that employment
(see Appendix B, p. 11). Mr. Turk stated that San Juan County is the most impoverished county in
the state of Utah and somewhere between the 8th and the 15th most impoverished county in the
United States (see Appendix B, p. 13). The person expressed the opinion that not supporting one
of the main economic engines of the local economy that supports a large portion of our
indigenous peoples and provides their livelihoods would be shortsighted. The person asserted
that opposing this proposal would fall short of being concerned for the life, liberty, pursuit of
happiness of the population that reside here.
Another person (Joe Lyman) stated that employment provided by the White Mesa mill is critical
(see Appendix B, p. 20). This person asserted that the mill provides employment to the very
people that some say should be protected from the mill. He added that not having that
employment could be devastating to the entire area.
Division Response: Non-substantive Comments.
Comments noted. No response required.
Public Participation Summary

PC-16; DUSA is Responsible and Professional
One commenter (Toni Turk) noted that there is a place for regulatory oversight, that is, to ensure
that development processes are appropriate and timely and that the necessary adjustments are
made as they are judged to be needed (see Appendix B, pp. 12-13). This person also expressed the
opinion that Denison Mines is good for the local community and area, that White Mesa
management are being good neighbors, and that they are being good contributors to the local
economy.
One person (Chris Webb, Blanding City Manager) stated that he had have been associated with
the mill most of his life (see Appendix B, p. 13). He reported watching the mill propose different
actions to promote viability of the milling operations. He also reported that proposals have
raised questions in the minds not only of Blanding citizens but of other people in the region and
that people get emotionally involved, arguing their love for the area and the surroundings and
expressing concern abut what any proposal might do. The person expressed his belief that
emotion should not be the only factor but that sciences also be considered. Mr. Webb stated his
experience in dealing with the mill over many years, that they are a very good steward, partner,
and community member (see Appendix B, p. 15).
One person (Joe Lyman) reported his impression that by and large White Mesa management has
been responsible with what they've done at the mill site (see Appendix B, p. 19). This person
reported seeing opposition to activity at the mill that has not been well founded This person
expressed his belief that he represented many people who, if they were able to come and speak,
would support the mill (see Appendix B, pp. 19-21).
Division Response: Non-substantive Comment.
Comments noted. No responses required.
PC-17; Balance in Preserving Archaeological Resources
One person (Bradley Angel) expressed concern and opposition to the proposed construction
because, it was argued, with the blessing of the State of Utah, the company is destroying
ceremonial, potential ceremonial, and well-documented culturally significant sites (see Appendix
B, pp. 9-10). It was stated that the desecration and absolute destruction of culturally significant
ancient sites could involve burials (not just some ancient artifact for a museum). These are part
of the living culture of the people here. Agency decisions and actions would help desecrate these
sites, continue to devastate the culture of the native peoples of this area, and we believe violate
the Civil Rights Act.
Division Response: Substantive Comment.
Please refer to the DRC’s response to Topic PC-01 above.
PC-18; Health and Safety Are Important
One person (Chris Webb) commented that, as a community, Blanding had approached the NRC
asking for factual information about health and threats to life and safety threats (see Appendix B,
pp. 14-15). He stated that health and life safety of our citizens is more important than any
economic development, although, economic development is an important part of a community, if
it can be done right. He expressed amazement at learning what was being done and all the

regulations in place to ensure public safety. The person reported that, as the NRC explained the
science and regulations, he became supportive of the [licensing and regulatory] processes and
became confident that those processes can continue if the regulations were followed.
Division Response: Non-substantive Comment.
Comment noted. No response required.
PC-19; Confidence in State and Federal Regulators
One person (Bradley Angel) asserted that DRC and other state agencies consistently fail to
assess the impacts of actual hazards that are documented, as well as potential future hazards to
the health and environment and cultural resources of this area (see Appendix B, p. 8-9).
One commenter (Toni Turk) noted that there is a place for regulatory oversight, that is, to ensure
that development processes are appropriate and timely and that the necessary adjustments are
made as they are judged to be needed (see Appendix B, pp. 12-13).
Division Response: Non-substantive Comment.
DUSA is required to conduct environmental monitoring of air, surface water, groundwater
resources and mill and site-related effluent emissions and submit results of such monitoring
activities to the DRC on an ongoing, regular basis. These reports are available to the public upon
request under GRAMA and are also available at the DRC office in Salt Lake City, Utah. The
DRC conducts public hearings, such as the May 4, 2010 Public Hearing in Blanding, to apprise
affected communities of planned activities at the White Mesa Mill Facility and to acquire public
input and encourage information exchange. Through reviews associated with License and
Groundwater Discharge Permit modifications such as this one, the DRC evaluates the potential
impacts of site activities on human health and the environment, including cultural resources.
Please also refer to DRC’s responses in this Public Participation Summary to other public
comments received.
PC-20; Release of Radioactive Materials to the Environment
One person(Bradley Angel) asked whether the DRC is aware of any time that radioactive
materials associated with this facility ended up not contained, such as by the highway (see
Appendix B, p. 26).
Another person (Chris Webb) assured that the monitoring is happening and that the state ensures
the monitoring takes place (see Appendix B, p. 29).
Division Response: Substantive Comment.
Prior to the DRC becoming an Agreement State in August, 2004, a radiologic survey of the entry
road to the mill and adjoining soils (borrow pit areas) was performed by DRC staff.. These
informal surveys found some soil activity at levels above background concentration. These
findings were communicated to DUSA management, and shortly thereafter, DUSA excavated the
soil in question and placed it on the ore storage pad (inside the restricted area) for processing.
Annual soil sampling and analysis is performed during the third quarter of each year at several
locations both inside and outside the restricted area. The result of this work is provided to DRC in
semi-annual effluent monitoring reports by DUSA.

Section 3. Sundry Changes to Permit and License
Selected, minor changes have been made to the Radioactive Materials License and the
Groundwater Discharge Permit after the Public Comment period ended. These changes are not
related to comments received during the Public Comment period, and are not substantive in
nature, but instead represent a simple wording change to correct a typographical error or slight
changes to reporting or compliance date or deadline to account for changes in the timetables for
documents to be submitted by DUSA for DRC review. These changes include the following:
1. License Condition 9.6 – The abbreviation “SOPs” for “standard operating procedures”
was added to the first sentence of this License Condition as follows: “Standard operating
procedures (SOPs) shall be established and followed for all operational process activities
involving radioactive materials that are handled, processed, or stored.”
2. License Condition 9.11 – The deadline for submittal of the revised Reclamation Plan
(Rev. 3.2) has been changed from June 1, 2010 to June 30, 2010.
3. License Condition 11.7.E(3) – In order to correct a typographical error, wording has been
changed to the following. “Review of the data and an analysis shall be performed and
certified by a Utah Licensed Professional Engineer and submitted ..."
4. License Condition 12.3 – The reporting deadline for the ATER (Annual Technical
Evaluation Report) has been changed from September 1st of each year to November 15th
of each year.
5. Permit Part I.E.10(a) – Minor typographical correction (removal of extra comma).

RE: Comments on White Mesa Uranium Mill: Modification to the Groundwater
Discharge Permit No. UGW37004 and Amendment 4 to Radioactive Materials License
No. UT1900479.

Dear Mr. Finerfrock:

The proposed License Amendment 4 to Radioactive Materials License No. UT1900479 is
for the construction of a new tailings impoundment at the White Mesa Uranium Mill,
owned and operated by Denison Mines (USA) Corporation (DUSA, or Applicant).
Below are comments on the license amendment and the Safety Evaluation Report:
Review of License Amendment Request and Environmental Report for Cell 4B.

1. WHITE MESA ARCHAEOLOGICAL RESOURCES

1.1. The construction of Cell 4B will impact a number of Archeological Resources at the
Mill site and in the White Mesa Archaeological District. White Mesa is in an area
adjacent to and in the vicinity of extensive tribal holdings and an area rich in
archaeological resources, which have been designated as significant and deserving of
preservation. Many Archaeological Resources on White Mesa have been found eligible
for the National Register, including resources that will be or have been impacted by
activities associated with the proposed license amendment.

The Licensee and the Utah Division of Radiation Control (DRC) have not complied with
the requirements of License Condition 9.7, which states, in pertinent part:

All disturbances associated with the proposed development will be
completed in compliance with the National Historic Preservation Act (as
amended) and its implementing regulations, and the Archaeological
Resources Protection Act (as amended) and its implementing regulations.

Utah Division of Radiation Control 2
May 10, 2010
Compliance with the National Historic Preservation Act includes compliance with
Section 106. The Safety Evaluation Report (SER) fails to discuss how the Applicant
fulfilled its responsibilities under the “National Historic Preservation Act (as amended)
and its implementing regulations, and the Archaeological Resources Protection Act (as
amended) and its implementing regulations.”

A contractor to the licensee has commenced excavation of the Archaeological Resources
at the Mill, with approval of the DRC. However, excavation has commenced without the
any Section 106 consultation. The excavation of the valuable Archeological Resource on
White Mesa has taken place without informing and consulting with nearby tribal
governments and tribal Historic Preservation Officers and without an opportunity for
public comment.

Further, the Licensee commenced activities that have impacts on the Archaeological
Resources and are the subject of License Condition 9.7 requirements prior to this
comment period and prior to the issuance of the license amendment and final
environmental evaluation.

All activities that impact Archaeological Resources at the Mill should cease until DRC
initiates and completes a Section 106 consultation process, including consultation with
affected tribal governments or appropriate tribal representatives. The DRC should not
issue the license amendment without consulting with the Ute, Navajo, and other regional
tribal Historic Preservation Officers regarding the destruction of irreplaceable historic
resources.

Further, the SER must include a discussion of how the Applicant has complied with the
provisions of License Condition 9.7.

1.2. LICENSE CONDITION 9.7.

The DRC is not proposing any changes to License Condition 9.7, which pertains to the
cultural resources at the Mill. License Condition 9.7 refers to a Memorandum of
Agreement (MOU) between the Utah State Historical Preservation Officer (SHAPO), the
Advisory Council on Historic Preservation (ACHP) the Nuclear Regulatory Commission
(NRC), and Energy Fuels Nuclear, Inc. (a former Mill owner/licensee). The MOU was
ratified on August 20, 1979, and amended on May 3, 1983. The MOU should be
amended or replaced, since it does not reflect the current situation at the Mill.

2. SAFETY EVALUATION REPORT (SER)

2.1. LICENSEE REPORTING RESPONSIBILITIES (SER, page 21).

The DRC should make the effluent monitoring reports, Semi-Annual Effluent Reports
and Quarterly Groundwater Monitoring Reports and any additional effluent monitoring
information submitted by the licensee pursuant to License Condition 11.2 available on
Utah Division of Radiation Control 3
May 10, 2010
the DRC website in a timely manner.

2.3. LONG TERM IMPACTS

UCA R313-24-3D: Environmental Analysis – Long Term Impacts, Safety Evaluation,
states that, pursuant to UAC R313-24-3, a major license amendment should include
"consideration of the long-term impacts." The SER discussion addresses long-term
impacts. However, the SER and the UCA section do not define long-term and leave the
issue of long-term containment of the mill tailings and their associated emissions to be
addressed in a future Reclamation Plan. Under current federal regulation (40 C.F.R. Sec.
192.32(B)(1)(i)1), consideration of the technical requirements for long-term containment
of the tailings is limited to "one thousand years, to the extent reasonably achievable, and,
in any case, for at least 200 years." The SER (page 30) gives states that Cell 4B has been
designed to provide "reasonable assurance that radiological hazards will be suitably
controlled for 1,000 years, to the extent reasonably achievable, and in any case for at
lease 200 years."

So, we have "reasonable assurance" to the extent that suitable control is "reasonably
achievable." What does this vague language mean over the long-term? The public, the
licensee, and the DRC do not really know.

The tailings will remain on White Mesa in perpetuity, that is, forever. Therefore impacts
from 200 to 1,000 years are short-term impacts, not long-term impacts, given the time
that the tailings will continue to release radon and will be a radioactive and hazardous
material requiring physical and regulatory control for as long as there are individuals and
entities capable of exercising that control.

1 40 CFR Sec. 192.32(B)(1)(i).
(1) Disposal areas shall each comply with the closure performance standard in Sec. 264.111 of
this chapter with respect to nonradiological hazards and shall be designed to provide reasonable
assurance of control of radiological hazards to (i) Be effective for one thousand years, to the
extent reasonably achievable, and, in any case, for at least 200 years, and, (ii) Limit releases of
radon-222 from uranium byproduct materials to the atmosphere so as to not exceed an average \2\
release rate of 20 picocuries per square meter per second (pCi/m2s).

\2\ This average shall apply to the entire surface of each disposal area over periods of at least one
year, but short compared to 100 years. Radon will come from both uranium byproduct materials
and from covering materials. Radon emissions from covering materials should be estimated as
part of developing a closure plan for each site. The standard, however, applies only to emissions
from uranium byproduct materials to the atmosphere.

Utah Division of Radiation Control 4
May 10, 2010
Eventually the liners will break down, eventually the tailings cover will erode, and
eventually the tailings and the associated radioactive and non-radioactive contaminants
will disperse into the air, water, and soils.

Any evaluation of the long-term impacts of the proposed licensing action must address
the potential impacts of the dispersion of the tailings from natural forces over the
thousands and millions of years that the tailings will remain in place.

2.4. PERMANENT ISOLATION WITHOUT ONGOING MAINTENANCE (SER, page
24)

10 CFR Part 40, Appendix A, Criterion 1, states that tailings should be disposed of in a
manner that no active maintenance is required to preserve conditions of the site.

There is no doubt that over the years, active maintenance will be required to preserve
conditions of the site. The Department of Energy (DOE) has already discovered that
active maintenance is required at some of the uranium mill sites that have been reclaimed
and that DOE have responsibility for, due to erosion. The DOE is actively looking at
different cover and tailings design systems because of the problems they have
encountered at these sites.

No matter what the design is, eventually the cover, tailings, and White Mesa itself, will
erode, as demonstrated by the geological landscape in the region. Any claim to continued
long-term isolation of the tailings--without active maintenance--via a man-made design is
not supportable.

The DRC should consult with the DOE and the Nuclear Regulatory Commission and take
into consideration recent studies and data regarding the effectiveness of tailings system
designs and materials to update the final cover design and materials requirements in order
to achieve the maximum long-term isolation of the tailings with minimal maintenance.
The DRC should not mislead the public and licensee into thinking that isolation of the
tailings for 1,000 and for the long-term future can take place without active maintenance.

2.5. IMPACTS OF DEWATERING OF THE TAILINGS CELL (SER, pages 25 – 26)

The discussion of the permanent isolation without ongoing maintenance (10 CFR Part 40,
Appendix A, Criterion 1) and the Reclamation Plan refer to the dewatering of the tailings
cell after the operational life of the cell. However, there is minimal discussion about two
of the primary problems encountered at uranium mills once operation has ceased and cell
dewatering commences. Once dewatering commences, the result is an increase in the
release of radon from the cell and an increase in windblown tailings. The SER mentions
the possibility of the use of "platform fill," but provides little information and analysis of
the use of fill or other means to minimize the emission of radon, hazardous and
radioactive particulates to the atmosphere and the environment.

Utah Division of Radiation Control 5
May 10, 2010
The SER should discuss in more detail the impacts of cell dewatering on the emission of
radon and other gases and hazardous and radioactive particulates and how these impacts
will be mitigated during the estimated 5.5 years between the cessation of cell operation
and the placement of an interim and final cover.

2.6. OFF SITE MEASURING DEVICES

The February 12, 2010, letter to Dave Frydenlund, DUSA, from Senes Consultants Ltd.,
states (page 2): Due to the inaccuracy of the radon measurement devices the mill is not
required to sample for environmental radon under its license."

The Application for Cell 4B and the SER fail to provide supportive documentation
regarding various types of radon measuring devices and their supposed “inaccuracy” to
justify the failure to measure environmental radon from Cell 4 B and other radon sources
at the Mill. This would include on- and off-site monitoring of radon.

The SER should include a full justification, with supporting documentation, of the on-
and off-site radionuclide monitoring programs, including monitoring of radon. If DUSA
is not required to sample for environmental radon and other radioactive releases on- and
off-site, the public must know why and have supporting technical bases.

2.7. EFFLUENT CONTROL DURING OPERATIONS (SER, pages 59 - 60)

The SER discusses compliance with 10 C.F.R. 40, Appendix A, Criterion 8, with respect
radioactive effluents from the mill and tailings impoundment. Criterion 8 includes the
requirement:

Milling operations producing or involving thorium byproduct material
must be conducted in such a manner as to provide reasonable assurance
that the annual dose equivalent does not exceed 25 millirems to the whole
body, 75 millirems to the thyroid, and 25 millirems to any other organ of
any member of the public as a result of exposures to the planned discharge
of radioactive materials, radon-220 and its daughters excepted, to the
general environment.

The SER fails to discuss how compliance with the above requirement for exposures to the
public will be measured and compliance will be assured with respect the release of the
discharge of radioactive materials from Cell 4B and other sources at the mill during the
operation of the tailings cell.

The SER should explain exactly how the Applicant will demonstrate compliance with
Criterion 8 with respect the emission from Cell 4B.

2.8. COMPLIANCE WITH OTHER FEDERAL AND STATE REGULATIONS

Utah Division of Radiation Control 6
May 10, 2010
The SER does not discuss required compliance with other state and federal regulations
prior to the commencement of construction of Cell 4 B. This would include compliance
with the requirements of 40 C.F.R. Part 61, Subpart A. Section 61.07 requires that
DUSA submit an application to the Utah Division of Air Quality (DAQ) for Cell 4B as a
new 40 C.F.R. Part 61, Subpart W regulated source and receive an approval from the
DAQ, pursuant to Section 61.08. Recently, DUSA was issued a Notice of Violation by
the Environmental Protection Agency for failure to comply with the Subpart A
application/approval process for the Arizona 1 uranium mine. Therefore, the DRC
should remind DUSA of their Part 61 responsibilities. Additionally, DUSA may be
required to amend their air quality permit for the non-radioactive emissions from the
uranium mill.

The White Mesa license should contain a condition that states that DUSA must comply
with all applicable federal and state regulations and statutes and a license condition that
states that DUSA cannot commence construction of Cell 4B until DUSA receives the
required approval as a new 40 C.F.R. Subpart W regulated source from the DAQ.

Thank you for the opportunity to comment.

P R O C E E D I N G S
MR. GOBLE: Okay, it's seven o'clock and
I'll go ahead and get started.
My name is Phil Goble. I'm with the
Division of Radiation Control, and today I have
Mr. David Rupp assisting me. We're here to take
public comment regarding the proposed changes for the
White Mesa Mill permit and also license amendment.
The way this will work today is, I'll go
ahead and make a brief statement, then I will open
the time over to you to speak.
The way we've set it up, and you saw our
public notice, is because we have two different
documents we're talking about today, the license and
also the permit. We're going to set it up so we'll
talk about the license first and then we'll talk
about the permit. So from seven to eight we'll talk
about the license, eight to nine we'll talk about the
permit. There may be some people who only want to
make comment on one of them, so we'll give them an
opportunity to let me know now, and if they would
like to leave, they can leave, so they don't have to
stay for the whole time. But if you want to stay for
the whole time, that's fine.

The way this is going to work is, I'll
give each and every person a chance to talk. You'll
have five minutes to speak. Everyone gets an
opportunity to speak. We have seven people to talk
right now. And then at the end of your five minutes,
what we'll do is -- actually, after four minutes
we'll say "one minute" to give you a warning, and
then we'll say "time." And then we'll need you to
stop your public comment, and the next person gets
the opportunity.
At the end of the public comment, after
everyone has had a chance, those who still have more
to say will get the opportunity to speak again. So
we want to hear everyone if they have anything to
say.
Also, the public comment period actually
doesn't close till this next Monday, on May the 10th.
So if you don't say everything you'd like to say and
you forget about it, you still have the opportunity
to make public comment. And you can submit that to
me either by e-mail, which is [e-mail], or you
can also mail that to us. Our address can be found
on our website, which is radiationcontrol.utah.gov.
So what I'd like to do now is, I'm going
to look at the list, and I want to determine who is

going to speak just on the license, who on the
permit, or who's going to speak on both. So it looks
like the first person here -- well, he actually says
he's unsure if he wants to make a comment or not, is
Steve Hancock. Do you want to make a comment?
MR. HANCOCK: I'm still not sure.
MR. GOBLE: Okay, we'll put you at the
end. The next person I have here is Bradley Angel.
MR. ANGEL: I'll just make one comment
addressing both.
MR. GOBLE: Okay. That sounds fine. So
you'll do both.
Okay. Next we have Toni Turk. Do you
want to do just the license or the permit, or both?
Or are you just making a general statement?
MR. TURK: Just a general statement.
MR. GOBLE: Okay. All right. And
Mr. Chris Webb?
MR. WEBB: One comment.
MR. GOBLE: Okay. And Ms. Fields?
MS. FIELDS: On both.
MR. GOBLE: Both. And Mr. Lyman?
MR. LYMAN: Both.
MR. GOBLE: Both.
Okay. Well, what I'll do first is, I'll

just tell you, I guess, what some of the changes are
for the permit and the license, and then we'll go
ahead and open up the public comment. And it looks
like the first person to speak will be Mr. Angel.
I'll let you know when that time has come.
So since we're going to be talking about
the license first, now, the big thing here is Denison
Mines have proposed to make a new tailings cell,
Tailings Cell 4B. That is the reason for having this
public meeting today. Some of the changes or
additions to the license include the submittal of an
updated Reclamation Plan and specifications for
approval to include Tailings Cell 4B, changes in
tailings cell wastewater freeboard requirements, the
submittal for approval for written Standard Operating
Procedures, and improvements for content for the
Annual Technical Evaluation Report.
And then regarding the permit, we have an
addition of a definition for engineering design
standards for the new Tailings Cell 4B, definition of
BAT performance standards for Tailings Cell 4B,
installation of at least three new monitoring wells
hydraulically downgradient of Tailings Cell 4B, the
submittal of an updated BAT monitoring plan for cell
4B, the submittal of an additional hydrogeologic

investigation report of nearby seeps and Ruin Spring,
and the submittal of an engineering as-built report
regarding Cell 4B.
So, do we have anyone else who's making
public comment? We have one more? Can you bring
that to me, please.
MR. RUPP: Sure. Actually, not.
Actually, it's a question. Maybe. It's a maybe.
MR. GOBLE: Okay. Mr. Taylor Lyman, you
have a question mark here. Are you wanting to make
comment?
MR. T. LYMAN: We'll see.
MR. GOBLE: Okay. Well, we can wait until
the end and I can ask you.
All right. Now, like I said, the first
person who will make public comment will be
Mr. Bradley Angel. And like I said, what we'll do is
we'll give you five minutes, you'll hear a one-minute
warning, and then we'll tell you "time." Then you
also have the opportunity to give your comment again.
So let's turn this over to Mr. Angel.
MR. ANGEL: Thanks. Good evening. Again,
my name is Bradley Angel, and my address is P.O. Box

Environmental Justice and on behalf of our
constituents in both Grand and San Juan County
including White Basin Ute community.
A few comments. One is that I've been
coming to hearings on this mill for a number of years
now, and I know it's not how your agency does this,
but it's a problem and it's a flaw that I didn't
receive notice. And unless you affirmatively sign up
on your website on the ListServ, you don't get these
notices.
And that might be something I can do, but
for people who are actually most directly affected by
decisions the state makes and is making around this
facility, it's a big problem. Because, for example,
a lot of folks at the White Basin Ute community are
low income and do not have regular access to
Internet. So the way the rules are set up
systemically makes it a reality that most folks who
are most affected have no idea this meeting is even
happening, and I think that's a real problem. And
one of the reasons it's such a big problem is that
your agency and other state agencies consistently
fail to assess the impacts of actual ones that are
documented as well as potential in the future on the
health and environment and cultural resources of this

area.
So, for example, you know, when was the
last time you all assessed the yellowcake coming out
of the stacks at the uranium mill? When is the last
time the people of White Mesa, the actual tribal
members, were informed about that? I don't know if
that ever happened.
For the discussion and issues before us
today, in particular we are very concerned and
opposed to this new construction that's proposed
because, once again, with the blessing of the State
of Utah, the company is destroying ceremonial,
potential ceremonial but certainly culturally
significant sites that are well documented, that,
just as you at the state, the people in this audience
would not want or churches and temples desecrated,
this once again with the state blessings is what's
happening.
We think not only is that unethical and
immoral, we also think it's illegal. And it doesn't
matter from our perspective if it's happening on
private land, because it's happening courtesy of
state permits.
The State of Utah has an obligation. You
are making consideration under federal rules. You

have delegated authority from the federal government
to run this program. And I would venture to guess
that the Division of Radiation Control receives some
other additional types of benefits, maybe financial
benefits, such as grant program or other support from
the federal government.
If any of that is true, which I think all
of it probably is, then the state once again is
violating the United States Civil Rights Act, Title
VI. And I've raised this before, and it's completely
ignored by the state.
As a recipient of federal funding, you are
prohibited from taking any actions that would have
discriminatory or disproportionate impact on low
income people of color, like the White Mesa Ute
people. It's illegal.
MR. RUPP: One minute.
MR. ANGEL: And the desecration and
absolute destruction of ancient sites that could
involve burials that are certainly culturally
significant, not just some ancient artifact for a
museum; they're part of the living culture of the
people here. And your agency, by the decisions
you've made in the past and by the one I believe
you're planning on approving, which you should not,

would not only help desecrate these sites, continue
to devastate the culture of the native peoples of
this area, and we believe violate the Civil Rights
Act. So we really want you to take a look at that
before any decisions are made. Thank you.
MR. GOBLE: Mr. Angel, did you want to
reserve any time for later?
MR. ANGEL: No. Thank you.
MR. GOBLE: All right. Our next person
will be a Mr. Toni Turk.
MR. TURK: Thank you. I appreciate the
opportunity to address this body. I'd like to
introduce myself. I'm the mayor of Blanding, and I
would like to respond to some of Mr. Angel's
comments. Since he is from Moab, he may not be, you
know, as informed about the communications and the
processes that occur here as someone that is local.
I would point out that White Mesa, Inc. is
a major employer of the White Mesa Ute community and
works in collaboration with Denison Mines for that
employment.
The other part to that is that Cleo
Bradford, who has worked very closely with the White
Mesa Utes, is very computer literate and is able to
receive and disperse all communications that pertain

to that community and, to my knowledge, does that.
In fact, they have a Ute meeting house just close to
this facility.
The other is, at Rotary Club recently we
had a detailed presentation of the archeological
recovery of knowledge that Denison Mines has funded,
and that has added significantly to the database of
understanding of the cultures that have lived here
anciently. And all of those artifacts that are
recovered and recovered according to archeological
procedure are made available for further research at
the Edge of the Cedars Museum.
Now, I would like to address the plans for
this expansion of the new cell and express confidence
in the science that the White Mesa management,
Denison Mines, their oversight that they have
exercised. If there was something that was going to
be going on ten miles from this community that was a
threat to this community, Blanding City would be the
first in line to be concerned. But we do have
confidence that they are professional and that good
science is going forward. And there is a place for
regulatory oversight, and that is to ensure that
those processes are appropriate and timely and that
the necessary adjustments are made as adjustments are

seen to be needed.
I would like to point out that San Juan
County is the most impoverished county in the state
of Utah. By some reckoning, it's somewhere between
the 8th and the 15th most impoverished county in the
United States. And to not support one of the main
economic engines that support this economy and
support a large portion of our indigenous peoples and
their livelihoods I think would be shortsighted. It
certainly would fall short of being concerned for the
life, liberty, pursuit of happiness of our population
that reside here.
And I would express the opinion that
Denison Mines is good for our community, it's good
for our area, and we have every confidence that they
are being good neighbors and that they are being good
contributors to our economy.
Those are my thoughts.
MR. GOBLE: All right. Thank you,
Mr. Turk. Our next person that wanted to speak is
Mr. Chris Webb.
MR. WEBB: Hello. My name is Chris Webb.

was involved in the construction of the mill, though
at that time was not aware at what point I might get
involved or be involved with the mill and their
operations there.
As I started my job as the Blanding City
manager 14 years ago, the mill operations have been
up and down. They've been able to propose different
actions out there again to continue to see the
further viability of the operations there.
As those things have happened, it's raised
questions in the minds not only of Blanding citizens
but of other people around in the region. And a lot
of people get very, very emotionally involved in
these things, saying, listen, we love the area, we
love the surroundings, and we're worried, what's this
going to do to us. And we can't get too caught up
emotionally. We have to rely on the sciences and we
have to get involved.
For those reasons, as a community we
approached the NRC and said, okay, tell us what's
real. We need to know if there is a health and life
safety threat here. We need to know if there is a
problem. Because again, as our mayor has just stated
previously, we'll be the first to step in line.
Because the health and life safety of our citizens is

more important than any economic development,
obviously; although, again, that's an important part
of a community if it can be done right.
So meeting with them and having the
sciences explained to us and what's happening and how
those protections are in place and what needs to
happen, it was amazing. It was absolutely amazing to
find out the things that have to be done and all the
regulations in place to ensure public safety.
The State of Utah, Blanding City, San Juan
County, none of us want to see anybody hurt or
damaged. And what we have found out in our
experience over the many, many years now in dealing
with the mill is that they are a very good steward
and a very good partner and a very good community
member. And if those regulations are followed to the
T, all the way down to what kind of pencil you can
use in making your reports and signing your names and
those kind of things, it's just amazing to me all the
regulations that you have to follow through.
And as those things, the sciences and
stuff were explained to us, we became very supportive
of the processes and became very confident that they
can continue those processes if those regulations
that are set up by the scientists that run our nation

and run our state. We appreciate that. Again,
emotions set aside, we support what's happening there
and want to speak in favor of that.
MR. GOBLE: All right. Thank you,
Mr. Webb. The next person that wanted to speak is
Ms. Fields.
MS. FIELDS: My name is Sarah Fields, and
I represent an organization named Uranium Watch in
Moab, Utah. And I thank you for the opportunity to
speak.
I agree with the previous speakers that
the regulations and the implementation of the
regulations by the licensee are very important. I
will be submitting some written comments, but I also
have a few oral comments.
First regards the archeological resources
at the mill. Currently archeological excavation is
taking place from either -- a few over ten
archeological sites are being excavated. Most of the
archeological sites on White Mesa are ancient pit
houses.
When the site was constructed in the late
1970's and early 1980's, there was extensive
archeological excavation. Artifacts were taken.
Some of those ended up at the University of Utah;

some of those ended up at Edge of the Cedars. And
yet in the past 30 years, none of those artifacts
have been exhibited at Edge of the Cedars, and there
have been no additional studies and there have been
no presentations related to that extensive
archeological excavation.
Although artifacts will be taken,
essentially these historic, to me, incredibly
beautiful and significant sites that could have been
the basis for a national monument here in San Juan
County, which would probably over the years have
brought more economic benefit to this area, these
sites will also be destroyed. They will be destroyed
by the construction of the mill.
So the essence of these sites will be
destruction. And as the mill expands, more sites
will be destroyed, because White Mesa of itself is an
archeological district, and I would think that the
community would have more of an interest in
preserving those sites.
I've talked with the NRC recently about
whether Section 106 consultation was required. I
have not yet gotten a response from them. They're
looking into this. But I think the failure of the
Division of Radiation Control and the failure of the

Utah Historical Society to consult with the White
Mesa Ute and the Ute Mountain tribal governments and
the Navajo tribal historic preservation is
unacceptable, and I feel the Division of Radiation
Control must consult with these entities before they
approve this license amendment.
Also, license condition 9.7 needs to be
stricken from the license. That license condition
pertains to cultural resources at the mill and refers
to a memorandum of agreement between the Utah State
historical preservation officer --
MR. RUPP: One minute.
MS. FIELDS: -- the advisory council in
historic preservation, the NRC and energy is nuclear.
This MOU is totally out of date. It's from 1979,
amended in 1983. It doesn't refer to the current
conditions of the license, so that license condition
should be reviewed and should be brought up to date.
Let's see. I'll just go on what I have
time for. Oh. Also, the Division of Radiation
Control should make the effluent monitoring reports
and any additional effluent monitoring information
submitted by the licensee pursuant to license
condition 11.2 available on the DRC website. You've
done a really good job to make all the documents

relating to this license amendment request, the cell
4A --
MR. RUPP: Time's up.
MS. FIELDS: -- the license available, and
I commend you for that. Thank you.
MR. GOBLE: Thank you, Ms. Fields. Would
you like to reserve some time after everyone else has
had the opportunity to speak?
MS. FIELDS: Yes.
MR. GOBLE: Okay. We'll go ahead and do
that for you. The next who wanted to speak was
Mr. Joe Lyman.
MR. J. LYMAN: I kind of stumbled into
finding out this meeting was happening, and I sent
out an e-mail to a few people, hoping they could get
here. And I'll address a thought to that a little
bit later.
But my impression of what's happened with
the mill over the years that it's been there, I
worked there for a period of time when I was younger,
is that by and large they've been very responsible
with what they've done. I think that Mr. Webb's
comments addressed that point.
I have seen at times, some of the
opposition to activity of the mill have not been well

founded. Maybe some of them have, maybe some of them
haven't; but I know there's been some of the
opposition expressed that turned out to not be
particularly well founded. So I can't address what
anybody is saying today. It's just been historical
observation.
I think the employment that they provide
is critical. As Mayor Turk illustrated, we're in an
extremely depressed economy, and a lot of the
employment that the mill provides is to the very
people that some say we should be protecting from the
mill. And it could be devastating to the entire area
to not have that employment and support that, which I
do.
I'm pretty sure we could probably have a
roomful of people here in support of the mill, but
they, like me, are businessmen who are trying to
provide for themselves and provide opportunities for
others to provide for their families. We're just too
busy. We're trying to make this country run, and
frankly, we're too busy trying to do that to spend a
lot of time and energy coming to these kinds of
meetings.
And on that note, I've still got work to
do tonight, so I've got to go. But I've got to think

I would represent 50 people if they only had the time
and the ability to become aware of these things to
come and speak and support the mill. I think they
would be here. So I support what they're trying to
do. Thank you.
MR. GOBLE: All right. Thank you,
Mr. Lyman.
So the next person, we have a Mr. Steve
Hancock. You had unsure. Would you like to make
a --
MR. HANCOCK: I'm good for now.
MR. GOBLE: All right, Steve. And another
person we have as kind of a maybe was Taylor Lyman.
Would you like to --
MR. T. LYMAN: No.
MR. GOBLE: No. Okay, Ms. Fields. And
presently we don't have anyone else on the list, so
go ahead and speak till you're done, I guess.
MS. FIELDS: I won't take too much time.
MR. GOBLE: Okay.
MS. FIELDS: In going over the safety
evaluation report, and I, too, have other employment
and did not have a lot of time to go over all of
this; but when you talk about long-term impacts of
the mill, it states that the SERs, which is the

Safety Evaluation Report, which is the environmental
analysis that you're required to do for a major
license amendment under the Atomic Energy Act; the
Atomic Energy Act has specific requirements for
agreement states, and the state of Utah is an
agreement state under the NRC's regulation under the
Atomic Energy Act where the federal government has
given the state of Utah the responsibility for
regulating uranium mills in Utah.
But when you talk about long-term impacts,
you don't really define what long-term impact means.
The SER states that Cell 4B has been designed to
provide reasonable assurance that radiological
hazards will be suitably controlled for 1,000 years
to the extent reasonably achievable, and in any case,
for at least 200 years. The federal regulations
limit the technical assessment for -- the technical
requirements for long-term containment of the
tailings to that 200-year to 1,000-year period.
However, we all know that those tailings
are going to be there in perpetuity, forever. So 200
to 1,000 years isn't a very long time period when you
think that they are going to be there forever and
ever.
So eventually the liners will break down,

the tailings cover will erode, and eventually the
tailings and associated radioactive and
nonradioactive contaminants will disperse into the
air, water, and soil. It's not a matter of if, it's
a matter of when. Most -- you, me, the people in
this room are not going to be here then. But there
still will be, hopefully, a population in this area.
And I think when the Division of Radiation
Control looks at the long-term impacts that they
really have to at least honestly assess what's going
to happen to those tailings 10,000 years from now --
you know, 2,000, 10,000, 100,000 years from now.
Also, in your SER you talk about isolation
without ongoing maintenance. And I think the
Division of Radiation Control in conjunction with the
NRC and in conjunction with the Department of Energy,
which now has responsibility, that's Department of
Energy now has the responsibility for long-term
maintenance for all the old type, what they call
Title I uranium mills, and for any uranium mills,
other uranium mills that have closed.
So they're finding out what the issues are
even over the short period of time of 50 years from
the closure of some of these sites. So they've been
discovering what some of the long-term maintenance

issues are, whether it's contamination of the
groundwater. And in the west there are billions of
gallons of groundwater that has been contaminated by
uranium mills.
So they're looking at groundwater
contamination, they're looking at the erosion, and
even now the Department of Energy is looking into
different types of caps for mill tailings, because I
think they're finding that some of the previously
designed caps that have been put in place are really
not as adequate as they had predicted.
So I think the Division of Radiation
Control with the NRC and the DOE should take a harder
look at what really -- what is a realistic long-term
maintenance scenario for White Mesa and for other
uranium mill tailing sites, whether in Utah or in
other states, and take advantage of the new data and
the new information that is being generated so that
when this tailing cell and the other tailing cell at
White Mesa are complete, have gone through operation,
they get covered, the plan, the long-term reclamation
plan is adequate.
Thank you.

to speak now?
MR. TURK: Is it possible for additional
comment?
MR. GOBLE: Absolutely, Mr. Turk. You can
come up, absolutely.
MR. TURK: The point that I would like to
bring forward at this time is, following Katrina,
that disaster on the Gulf Coast, which was
devastating to our country, the Associated Press
conducted a study to determine what city in the
United States would be the safest city from natural
disaster, and they came to the conclusion that
Blanding would be that city. And that was an AP
publication.
I think that really speaks to the
substructure of the land that we're in. We're not in
an earthquake prone area. We don't have significant
natural disturbance in this area. It would seem that
if you're going to have a location to contain the
materials that need to be contained when we're, you
know, talking in terms of many years into the future,
it would seem that this would be a place that would
certainly rise to the top as a location that would
have a long-term, secure dynamic coming from nature
itself.

So with that in mind, I believe that
this -- you know, with science, with nature, we have
the potential to create what we need to create in
order to produce the energy that this nation is going
to require.
There's been a lot of debate about nuclear
energy, and that's not what this meeting's about; but
on the green side of the equation, nuclear energy is
free from a lot of the downsides of other energy
forms. So I just want to add that part.
MR. GOBLE: All right. Thank you,
Mr. Turk.
Let's see. Also, Mr. Angel, do you have
more? And then we'll follow up with Mr. Webb.
MR. ANGEL: Bradley Angel. You know,
science that allows radioactive materials to be
unprotected and unwatched and have no provisions for
it for thousands of years after Denison Mines is gone
and we're all gone is a big problem. And as we all
know, for example, in this area the wind blows pretty
fiercely, and leaving radioactive materials blowing.
I would also ask you if the state agency is aware of
any time, for example, that radioactive materials
associated with this facility ended up not contained,
such as by the highway.

And again, you know, issues of what comes
out in the stack, particularly yellowcake. When was
the last time? I think that's really important,
because we're all in a need for good economy, for
health as well. And I think that is more important
than that. But, you know, people also have a right
in our democracy to know what they're being exposed
to, and I don't think that information's been fully
disclosed; and I know for a fact in talking to a
number of tribal members over the years, they did not
know, for example, that yellowcake was coming out of
that stack. And that's unacceptable.
In terms of an economic boom, I think if
you look at, in one short sentence, there's an
economic boom in Moab right now resulting in the
cleanup of the radioactive pile of tailings from the
old Atlas Mill. But that's not a good situation.
It's costing taxpayers millions and millions and
millions of dollars. So I think we need to be
protective of health.
Also that, whatever your perspective, if
you're for this facility, against it, don't know, I
again want to say that it's not just enough that
Mr. Bradford at White Mesa, Inc. knew about this. We
know a number of tribal members, at least, I can't

speak for all, had no idea this was going on tonight.
And that's why I think the state has to do a better
job and change the rules to ensure that in a
democracy people have the right to exercise their
democrat rights to participate in decisions that
affect their lives, and that includes knowing about
meetings like this. But thank you.
MR. GOBLE: Thank you, Mr. Angel.
Mr. Webb, you wanted to say more?
MR. WEBB: I did. Just a couple points,
hearing these additional comments.
There's a lot of things, being in a city
position and having to go through this process
myself. In addition to a city manager, I'm also the
environmental certifying officer for the city, state
recognized. We've got to go through these processes
all of the time.
And there's a lot of these existing laws
that we'd like to see changed one way or the other.
It's been addressed here tonight. I think the state
ought to change the rules. They ought to do this,
they ought to do that. And some of those rules will
probably go through a process of change.
I also sat on the State Division of
Drinking Water board for eight years, went through

all kinds of processes and public processes in these
rules. And there's people that come in all the time
saying, these rules need to change; we've got to get
tougher, because what if, what if, what if.
Well, some of those "what ifs," as we
discover more and the sciences change and they're
saying that rules need to be changed, great, change
them. But these applications before you today aren't
about those what ifs. And yeah, and this a good
forum to encourage the state to change the rules.
But these applications ought to be judged today on
today's rules and the rules that are today in place.
And if those rules at some point require additional
monitoring, great.
But I can tell you that the monitoring is
happening, that the state ensures the monitoring's
happening, and that the rules are being followed as
they are in place. And so we encourage the state to
make sure that when they judge these applications for
processes that they're judging them based on today's
rules, not on hopes for changes in future rules, but
those rules are changed today.
The other point that I wanted to make is
with regard to archaeology. We understand the
important heritage that comes to the citizens of our

community in these archeological sites. The city of
Blanding is over 40 percent Native American, so we
understand how important those sites are, and we
spend as a city in doing our projects hundreds of
thousands of dollars in collecting data, in analyzing
that data so that we can find out and make sure that
we're not letting some valuable resource go or some
valuable data go.
But as we go to an area like our big
reservoir, when we went out there and put in out Big
Fork Reservoir, there are so many sites in our area
that nothing would happen if we didn't let any site
go. So sometimes sites have to be mitigated. We
collect all the data we can, and then a site is
covered, or could even be lost after that process
happens.
So we understand that process is
happening, that these applications -- through these
applications that that process is happening, that the
mill has spent hundreds of thousands of dollars in
collecting data so that they too could move forward
with their projects. And we would encourage that in
this case, that these applications be approved.
MR. GOBLE: Thank you, Mr. Webb.

to speak, we don't have anyone else that signed up.
We're scheduled until 9 o'clock. So what we'll do
right now is, I'm going to go ahead and call a
recess. We'll call a recess for -- let's see. Right
now the time is -- it's 7:42. Let's call a recess
until 8:15 and see if anyone shows up.
For those that are here, you guys are
welcome to stay. You might have more comment in the
future. And we're going to be here for I guess the
next half hour to see if anyone else wants to show up
and make comments. So I'm going to go ahead and call
a recess right now, and we'll take pretty much a
half-hour break.
(Recess from 7:42 p.m. to 8:15 p.m.)
MR. GOBLE: The time is now 8:15. We'll
go ahead and open back up the meeting. It looks like
no one else has signed up to make public comment. So
do any of you gentlemen who are here want to make
comment? Okay.
I just want to let you guys know that
public comment can be received up to 5 o'clock on
Monday, May 10th. And like I said, you can either
e-mail that to me at [e-mail], or you can go
on our website and you can find our address and mail
it to us. And so long as it has the postmarked date

I forgot to thank Vicky here. The person
who was helping us today is Vicky McDaniel. I forgot
to introduce her earlier today, so I wanted to do
that now.
Since we don't have anyone else to make
public comment, I'm going to go ahead and call this
meeting ended. So this meeting is now adjourned.
Thank you for attending, and when we have one in the
future, we'd like your presence again. So thank you
very much.

[Applicable NRC Amendment: 5][Applicable UDRC Amendment 3]

11.3 The licensee shall implement a monitoring program of the leak detection systems for disposal
Cells 4A and 4B in accordance with requirements of the Ground Water Discharge Permit. The
licensee shall implement a monitoring program of the leak detection systems for disposal Cells
1, 2, and 3 as follows:

A. The licensee shall measure and record the “depth to fluid” in each of the tailings
disposal cell standpipes on a weekly basis. If sufficient fluid is present in the leak
detection system (LDS) of any cell, the licensee shall pump fluid from the LDS, to the
extent reasonably possible, and record the volume of fluid recovered. Any fluid pumped
from an LDS shall be returned to a disposal cell.

If fluid is pumped from an LDS, the licensee shall calculate the flow rate by dividing the
recorded volume of fluid recovered by the elapsed time since fluid was last pumped or
increases in the LDS fluid levels were recorded, whichever is the more recent. The
licensee shall document the results of this calculation.

B. Upon the initial pumping of fluid from an LDS, the licensee shall collect a fluid sample
and analyze the fluid for pH and the parameters listed in paragraph A of this license
condition. The licensee shall determine whether the LDS fluid originated from the
disposal cell by ascertaining if the collected fluid contains elevated levels of the
constituents listed in paragraph A of this license condition or has a pH level less than
5.0. If either elevated constituent levels or a pH less than 5.0 is observed, the licensee
shall assume that the disposal cell is the origin of the fluid.

If the LDS fluid is determined not to have originated from the disposal cell, the licensee
shall continue with weekly measurements of “depth to fluid” in the LDS standpipes. The
licensee shall confirm, on an annual basis, that fluid from the disposal cell has not
entered the LDS by collecting (to the extent possible) and analyzing an LDS fluid
sample for the above stated parameters.

C. Upon indication that the LDS fluids originated from the disposal cell, the licensee shall
determine the flow rate through the liner by the calculation method in paragraph B of
this license condition. If the flow rate is equal to or greater than one gallon per minute,
the licensee shall:

(1) Evaluate the cause of the liner distress and take appropriate and timely actions to
mitigate the leak and any consequent potential impacts;
(2) Continue to measure and record LDS “depth to fluid” measurements weekly;
and
(3) Notify the Executive Secretary by telephone within 48 hours, in accordance with
License Condition 9.2, and submit a written report within 30 calendar days of
notifying the Executive Secretary by telephone, in accordance with License
Condition 9.2. The written report shall include a description of the mitigative
action(s) taken and a discussion of the mitigative action results.

If the calculated flow rate is less than one gallon per minute, the licensee shall continue
with weekly measurements of “depth to fluid” in the LDS standpipes.

D. All sampling, analysis, and evaluation of LDS fluids shall be documented and retained
onsite until license termination for Executive Secretary inspection.
[Applicable NRC Amendment: 8] [Applicable UDRC Amendment 3] [Applicable UDRC
Amendment: 4]

11.4 Annually, the licensee shall collect, during mill operations, a set of air samples covering eight
hours of sampling, at a high collection flow rate (i.e., greater than or equal to 40 liters per
minute), in routinely or frequently occupied areas of the mill. These samples shall be analyzed
for gross alpha. In addition, with each change in mill feed material or at least annually, the
licensee shall analyze the mill feed or production product for U-nat, Th-230, Ra-226, and Pb-
210 and use the analysis results to assess the fundamental constituent composition of air sample
particulates.
[Applicable NRC Amendment: 7]

11.5 Calibration of in-plant air and radiation monitoring equipment shall be performed as specified in
the license renewal application, under Section 3.0 of the “Radiation Protection Procedures
Manual,” with the exception that in-plant air sampling equipment shall be calibrated at least
quarterly and air sampling equipment checks shall be documented.

Footnotes:
1) N = Number of Samples
2) Based on historic total dissolved solids (TDS) data provided by the Permittee for period between October, 1979 and December, 2007. This
data was obtained from the Permittee’s background groundwater quality reports dated October 2007 and April 30, 2008.
3) Background concentrations of uranium in well MW-18 (55.1 µg/L) and thallium in MW-19 (2.1 µg/L) exceed the GWQS, 30 µg/L and 2.0
µg/L, respectively. Therefore these wells have been classified as Class III groundwater rather than Class II groundwater.
4) Wells MW-20 and MW-22 are not point of compliance monitoring wells, but instead are groundwater head monitoring wells as per Part I.E.2.
Average concentrations and standard deviations for wells MW-20 and MW-22 were calculated by DRC staff from data from the DUSA 2nd
and 3rd Quarters of 2008 Routine Groundwater Monitoring Reports.
5) Background concentration of manganese in well MW-25 (1,806 µg/L) exceeds the GWQS, therefore well MW-25 has been classified as Class
III groundwater rather than Class II groundwater.
6) Well MW-26 was originally named TW4-15 and was installed as part of the chloroform contaminant investigation at the facility. Under this
Permit, MW-26 is defined as a Point of Compliance (POC) well for the tailings cells (see Part I.E.1).
7) Background concentrations of uranium in well MW-27 (34 µg/L) and selenium in MW-31 (71 µg/L) exceed the GWQS, therefore these wells
have been classified as Class III groundwater rather than Class II groundwater.
8) Well MW-32 was originally named TW4-17 and was installed as part of the chloroform contaminant investigation at the facility. Under this
Permit it is included as a POC well for the tailings cells in Part I.E.1.
B. BACKGROUND WATER QUALITY - based on groundwater samples collected through June 2007 for

a) Tailings Cell 1 - consisting of the following major design elements:
1) Cross-valley Dike and East Dike - constructed on the south side of the pond of native
granular materials with a 3:1 slope, a 20-foot crest width, and a crest elevation of
about 5,620 ft above mean sea level (amsl). A dike of similar design was constructed
on the east margin of the pond, which forms a continuous earthen structure with the
south dike. The remaining interior slopes are cut-slopes at 3:1 grade.
2) Liner System - including a single 30 mil PVC flexible membrane liner (FML)
constructed of solvent welded seams on a prepared sub-base. Top elevation of the
FML liner was 5,618.5 ft amsl on both the south dike and the north cut-slope. A
protective soil cover layer was constructed immediately over the FML with a
thickness of 12-inches on the cell floor and 18-inches on the interior sideslope.
3) Crushed Sandstone Underlay - immediately below the FML a nominal 6-inch thick
layer of crushed sandstone was prepared and rolled smooth as a FML sub-base layer.
Beneath this underlay, native sandstone and other foundation materials were graded
to drain to a single low point near the upstream toe of the south cross-valley dike.
Inside this layer, an east-west oriented pipe was installed to gather fluids at the
upstream toe of the cross-valley dike.

b) Tailings Cell 2 - which consists of the following major design elements:
1) Cross-valley Dike - constructed at the south margin of Cell 2 of native granular
materials with a 3:1 slope, a 20-foot crest width, and crest elevation of about 5,615 ft
amsl. The east and west interior slopes consist of cut-slopes with a 3:1 grade. The
Cell 1 south dike forms the north margin of Cell 2, with a crest elevation of 5,620 ft
amsl.
2) Liner System - includes a single 30 mil PVC FML liner constructed of solvent
welded seams on a prepared sub-base, and overlain by a slimes drain collection
system. Top elevation of the FML liner in Cell 2 is 5,615.0 ft and 5,613.5 ft amsl on
the north and south dikes, respectively. Said Cell 2 FML liner is independent of all
other disposal cell FML liners. Immediately above the FML, a nominal 12-inch (cell
floor) to 18-inch (inside sideslope) soil protective blanket was constructed of native
sands from on-site excavated soils.
3) Crushed Sandstone Underlay - immediately below the FML a nominal 6-inch thick
layer of crushed sandstone was prepared and rolled smooth as a FML sub-base layer.
Beneath this underlay, native sandstone and other foundation materials were graded
to drain to a single low point near the upstream toe of the south cross-valley dike.
Inside this layer, an east-west oriented pipe was installed to gather fluids at the
upstream toe of the cross-valley dike.
4) Slimes Drain Collection System immediately above the FML a nominal 12-inch thick
protective blanket layer was constructed of native silty-sandy soil. On top of this
protective blanket, a network of 1.5-inch PVC perforated pipe laterals was installed
on a grid spacing interval of about 50-feet. These pipe laterals gravity drain to a 3-
inch diameter perforated PVC collector pipe which also drains toward the south dike
and is accessed from the ground surface via a 24-inch diameter, vertical non-
perforated HDPE access pipe. Each run of lateral drainpipe and collector piping was
covered with a 12 to 18-inch thick berm of native granular filter material. At cell
closure, leachate head inside the pipe network will be removed via a submersible
pump installed inside the 24-inch diameter HDPE access pipe.
c) Tailings Cell 3 - consisting of the following major design elements:
1) Cross-valley Dike - constructed at the south margin of Cell 3 of native granular
materials with a 3:1 slope, a 20-foot crest width, and a crest elevation of 5,610 ft
amsl. The east and west interior slopes consist of cut-slopes with a 3:1 grade. The
Cell 2 south dike forms the north margin of Cell 3, with a crest elevation of 5,615 ft
amsl.
2) Liner System - includes a single 30 mil PVC FML liner constructed of solvent
welded seams on a prepared sub-base, and overlain by a slimes drain collection
system. Top elevation of the FML liner in Cell 3 is 5,613.5 ft and 5,608.5 ft amsl on
the north and south dikes, respectively. Said Cell 3 FML liner is independent of all
other disposal cell FML liners.
3) Crushed Sandstone Underlay - immediately below the FML a nominal 6-inch thick
layer of crushed sandstone was prepared and rolled smooth as a FML sub-base layer.
Beneath this underlay, native sandstone and other foundation materials were graded

to drain to a single low point near the upstream toe of the south cross-valley dike.
Inside this layer, an east-west oriented pipe was installed to gather fluids at the
upstream toe of the cross-valley dike.
4) Slimes Drain Collection Layer and System - immediately above the FML, a nominal
12-inch (cell floor) to 18-inch (inside sideslope) soil protective blanket was
constructed of native sands from on-site excavated soils (70%) and dewatered and
cyclone separated tailings sands from the mill (30%). On top of this protective
blanket, a network of 3-inch PVC perforated pipe laterals was installed on
approximately 50-foot centers. This pipe network gravity drains to a 3-inch
perforated PVC collector pipe which also drains toward the south dike, where it is
accessed from the ground surface by a 12-inch diameter, inclined HDPE access pipe.
Each run of the 3-inch lateral drainpipe and collector pipe was covered with a 12 to
18-inch thick berm of native granular filter media. At cell closure, leachate head
inside the pipe network will be removed via a submersible pump installed inside the
12-inch diameter inclined access pipe.

Tailings Cell 4A Design and Construction - approved by the Executive Secretary will consist
of the following major elements:
a) Dikes - consisting of existing earthen embankments of compacted soil, constructed by the
Permittee between 1989 and1990, and composed of four dikes, each including a 15-foot
wide road at the top (minimum). On the north, east, and south margins these dikes have
slopes of 3H to 1V. The west dike has an interior slope of 2H to 1V. Width of these dikes
varies; each has a minimum crest width of at least 15 feet to support an access road. Base
width also varies from 89-feet on the east dike (with no exterior embankment), to 211-
feet at the west dike.
b) Foundation - including existing subgrade soils over bedrock materials. Foundation
preparation included excavation and removal of contaminated soils, compaction of
imported soils to a maximum dry density of 90%. Floor of Cell 4A has an average slope
of 1% that grades from the northeast to the southwest corners.
c) Tailings Capacity - the floor and inside slopes of Cell 4A encompass about 40 acres and
have a maximum capacity of about 1.6 million cubic yards of tailings material storage (as
measured below the required 3-foot freeboard).
d) Liner and Leak Detection Systems - including the following layers, in descending order:
1) Primary Flexible Membrane Liner (FML) - consisting of impermeable 60 mil high
density polyethylene (HDPE) membrane that extends across both the entire cell floor
and the inside side-slopes, and is anchored in a trench at the top of the dikes on all
four sides. The primary FML will be in direct physical contact with the tailings
material over most of the Cell 4A floor area. In other locations, the primary FML will
be in contact with the slimes drain collection system (discussed below).
2) Leak Detection System - includes a permeable HDPE geonet fabric that extends
across the entire area under the primary FML in Cell 4A, and drains to a leak
detection sump in the southwest corner. Access to the leak detection sump is via an
18-inch inside diameter (ID) PVC pipe placed down the inside slope, located between
the primary and secondary FML liners. At its base this pipe will be surrounded with a
gravel filter set in the leak detection sump, having dimensions of 10 feet by 10 feet by
2 feet deep. In turn, the gravel filter layer will be enclosed in an envelope of
geotextile fabric. The purpose of both the gravel and geotextile fabric is to serve as a
filter.
3) Secondary FML - consisting of an impermeable 60-mil HDPE membrane found
immediately below the leak detection geonet. Said FML also extends across the
entire Cell 4A floor, up the inside side-slopes and is also anchored in a trench at the
top of all four dikes.
4) Geosynthetic Clay Liner - consisting of a manufactured geosynthetic clay liner (GCL)
composed of 0.2-inch of low permeability bentonite clay centered and stitched
between two layers of geotextile. Prior to disposal of any wastewater in Cell 4A, the
Permittee shall demonstrate that the GCL has achieved a moisture content of at least
50% by weight. This item is a revised requirement per DRC letter to DUSA dated
September 28, 2007.
Part I.D
Permit No. UGW370004

e) Slimes Drain Collection System - including a two-part system of strip drains and
perforated collection pipes both installed immediately above the primary FML, as
follows:
1) Horizontal Strip Drain System - is installed in a herringbone pattern across the floor
of Cell 4A that drain to a “backbone” of perforated collection pipes. These strip
drains are made of a prefabricated two-part geo-composite drain material (solid
polymer drainage strip) core surrounded by an envelope of non-woven geotextile
filter fabric. The strip drains are placed immediately over the primary FML on 50-
foot centers, where they conduct fluids downgradient in a southwesterly direction to a
physical and hydraulic connection to the perforated slimes drain collection pipe. A
series of continuous sand bags, filled with filter sand cover the strip drains. The sand
bags are composed of a woven polyester fabric filled with well graded filter sand to
protect the drainage system from plugging.
2) Horizontal Slimes Drain Collection Pipe System - includes a “backbone” piping
system of 4-inch ID Schedule 40 perforated PVC slimes drain collection (SDC) pipe
found at the downgradient end of the strip drain lines. This pipe is in turn overlain by
a berm of gravel that runs the entire diagonal length of the cell, surrounded by a
geotextile fabric cushion in immediate contact with the primary FML. In turn, the
gravel is overlain by a layer of non-woven geotextile to serve as an additional filter
material. This perforated collection pipe serves as the “backbone” to the slimes drain
system and runs from the far northeast corner downhill to the far southwest corner of
Cell 4A where it joins the slimes drain access pipe.
3) Slimes Drain Access Pipe - consisting of an 18-inch ID Schedule 40 PVC pipe placed
down the inside slope of Cell 4A at the southwest corner, above the primary FML.
Said pipe then merges with another horizontal pipe of equivalent diameter and
material, where it is enveloped by gravel and woven geotextile that serves as a
cushion to protect the primary FML. A reducer connects the horizontal 18-inch pipe
with the 4-inch SDC pipe. At some future time, a pump will be set in this 18-inch
pipe and used to remove tailings wastewaters for purposes of de-watering the tailings
cell.
f) Cell 4A North Dike Splash Pads - three 20-foot wide splash pads will be constructed on
the north dike to protect the primary FML from abrasion and scouring by tailings slurry.
These pads will consist of an extra layer of 60 mil HDPE membrane that will be installed
in the anchor trench and placed down the inside slope of Cell 4A, from the top of the
dike, under the inlet pipe, and down the inside slope to a point 5-feet beyond the toe of
the slope.
g) Cell 4A Emergency Spillway - a concrete lined spillway will be constructed near the
western corner of the north dike to allow emergency runoff from Cell 3 into Cell 4A.
This spillway will be limited to a 6-inch reinforced concrete slab set directly over the
primary FML in a 4-foot deep trapezoidal channel. No other spillway or overflow
structure will be constructed at Cell 4A. All stormwater runoff and tailings wastewaters
not retained in Cells 2 and 3, will be managed and contained in Cell 4A, including the
Probable Maximum Precipitation and flood event.

PART IV. GENERAL REQUIREMENTS

possible of any planned physical alterations or additions to the permitted facility. Notice is

in the permitted facility or activity which may result in noncompliance with Permit requirements.
C. PERMIT ACTIONS. This Permit may be modified, revoked and reissued, or terminated for cause.

termination, or a notification of planned changes or anticipated noncompliance, does not stay any

the expiration date of this Permit, the Permittee must apply for and obtain a new permit. The
application should be submitted at least 180 calendar days before the expiration date of this

reasonable time, any information which the Executive Secretary may request to determine
whether cause exists for modifying, revoking and reissuing, or terminating this Permit, or to
determine compliance with this Permit. The Permittee shall also furnish to the Executive
Secretary, upon request, copies of records required to be kept by this Permit.
