Re: Response to Utah Division of Radiation Control ("DRC")
Information, Notice of Enforcement Discretion and Confirmatory
Storm Water Inspection at White Mesa Uranium Mill
August 8, 2012 Request for
Action regarding June 21,2012
Dear Mr. Lundberg:
This letter responds to DRC's above-named letter dated August 8,2012, which Energy Fuels Resources
(USA) Inc. ("EFR") received on August 10,2012, regarding the June 21,2012 storm water inspection
at White Mesa Mill.
For ease of review, this letter provides each of DRC's comments verbatim in italics, below, followed by
EFR's response.

DRC Comment
1. Standing water was observed in the area of the clean water tank, from an overflow or line break
at a shed (prmp house?) south of the tank. Please provide an explanation of the cause of the
standing water and verification that the issue is resolved and that the standing water is
eliminatedfrom that location within 30 calendar daysfrom your receipt of this letter.
EFR Response:
The standing water which DRC observed outside a shed in the area near the clean water (service water)
tank resulted from drainage from the potable water treatment shed. Overflow water from vessels in the
potable water building is channeled outside the building through a floor drain pipe which discharges at the
bottom of the west wall of the building. The small volume of standing water was removed (evaporated)
within 24 hours of DRC's June 2012 inspection. EFR proposes to construct an extension to the drain pipe
to gravity drain any overflow water to the concrete channel adjacent to the service water tank, which
flows to the tailings area.
The pipe extension will be completed on
DRC's inspection letter).

DRC Comment
2. The DUSA Spill Prevention, Control, and Countermeasures Plan, Part 1.6.1 requires the
documentation of a daily inspection of the propane tanks. Please include the inspection findings
with the daily inspection form used for storm water inspection documentation within 30 days
/rom your receipt of this letter.
EFR Response:
Section 1.5 through 1.6.1 of EFR's Spill Prevention Control and Counterrneasures ("SPCC") Plan was
intended to identiff liquid reagent chemicals and solutions which contents would require management or
cleanup of liquids if spilled or leaked from the storage vessel. Per the Handbook of Thermodynamic
Tables and Charts (K. Raznjevic,lgT6), the boiling temperature of propane at760 mm of Hg is -42.6"C
(-45"F), that is, propane is a gas at ambient conditions and would be immediately vaporized under all
foreseeable leakage conditions at the Mill. Moreover, no spill reportable quantity ("RQ") has been
identified for propane.
Since it is not meaningful to inspect the propane storage area for signs of liquid spills, EFR proposes as
agreed to in EFR's August 2,2012 telephone conversation with DRC, to remove the requirement from the
Spill Prevention Control and Countermeasures Plan.
The propane storage area will continue to be inspected each shift, as are other process equipment and
process areas, and any observations will continue to be recorded in the shifter's inspection report.
A revised version of the SPCC Plan in redline/strikeout format along with a clean copy are provided as
Attachment 1. The revisions include:
o the removal of propane from the SPCC Plan,o minor grammatical changes to the SPCC Plan for clarity, and
. update of the plan to reflect the current operator of the Mill, Energy Fuels Resources (USA) Inc.,
along with current names and titles of responsible personnel.
Following DRC approval of the proposed revisions, EFR will provide a signed copy certified by a Utah
Registered Professional Engineer.
EFR has also identified an inconsistency in the Storm Water Best Management Practice Plan
(*SWBMPP"). As discussed in Section 2 of the SWBMPP, the SWBMPP identifies practices to
prevent spills of chemicals and hazardous materials and minimize spread of particulates from
stockpiles and tailings management areas; and the requirements and methods for management,
recordkeeping, and documentation of hazardous material spills are not part of the SWBMPP and
are addressed separately in other documents, specifically, the Spill Prevention Control and
Countermeasures ("SPCC") Plan, the Emergency Response Plan ("ERP"), and the housekeeping
procedures within Mill SOPs. Previous versions of the SWBMPP incorrectly included the SPCC
Plan and ERP as appendices. For clarity and consistency, EFR proposes removing those
documents from the SWBMPP appendices and maintaining them as stand-alone documents. This
also eliminates the need to revise the SWBMPP when revisions are made to the SPCC or ERP.

Notice of Enforcement Discretion
DRC Comment
1. The Utah Ground Water Permit, Permit No. UGW370004, Part I.D.l0 requires that "the Permittee
will manage all contact and non-contact stormwater and control contaminant spills at the facility in
accordance with the currently approved Stormwqter Best Management Practices Plan." The approved
Best Management Practices Plan, Appendix l, Part 1.11 Personnel Training and Spill Prevention
Procedures requires that "all new employees are instructed on spills at the time they are employed and
trained. They are briefed on chemical and petroleum spill prevention and control. They are informed that
leal<s in piping, valves, and sudden discharges from tanks should be reported immediately. Abnormal
flows from ditches or impoundments are of immediate concern. In addition, a safety meeting is presented
annually by the Environmental Health and Safety Manager to review the SPCC plan." Additionally, Part
l.1l.l Training Records requires that "Employee training records on chemical and petroleum spill
prevention are maintained in the general safety trainingfiles."
During the June 21, 2012 Wite Mesa Mill stormwater inspection, the DRC inspectors requested copies
of the training records required by the S\IrPPP as well as a course outline for the material presentations,
in response they received;
A. Copies of certificationformsfrom the Environmental Protection Manual, Section 3.1, Appendix C
regarding certification thst the undersigned received instruction of the tailings system including
documentation of daily tailings inspections, analysis of potential problems and notification
procedures and safety (3 forms total), and,
B. A Copy of Appendix B of the Environmental Protection Manual, Section 3.1 "Tailings Inspector
Training" which includes an outline of the training program.
Per review of the provided documents DRC noted that the training did not provide instruction for items
required by the Permit Part 1.D.10 or any other topics related to spill prevention, control or storm water
pollution prevention. Additionally, it was noted that no records for new employees were provided, only
three forms were providedfor the following employees: David Turk, Tanner Holliday and Garuin Palmer.
DUSA is in violation of the Permit Part LD. l0 for failing to provide employee training as required by the
SWPPP.
DRC is extending enforcement discretion regarding this violation based on:
A. This was theJirst time that DRC has reviewed the training syllabus, and,
B. DUSA will comply with the Confirmatory Action section, item 2 below which requires the
development of a training program in compliance with the Permit within the specified time-line.

2. Storm Water Inspector Training - DUSA will implement a training progrom in compliance with
the SWBMPP Appendix l, Part l.l I and will provide DRC a copy of the course syllabus, training
calendar, and commitment to maintain training logs/certificates at the Mill within 60 calendar
days of receipt of this leuer.
DRC also notes that per a letter submitted to the Director by DUSA (dated October 17, 2011) in
response to a DRC RFI (dated September l,20ll), page 2 ltem 3. DUSA provides information
regarding the newly implemented internal notification process for small quantity spills and
commits that "all Mill employees will be trained to advise Mill environmental personnel of any
spills that they observe during the day, and these will also be noted in the daily inspection form. "
Although the DUSA letter does not specify how the information will be provided to the Mill
employees, DUSA has agreed that this information will be provided during the newly
implemented SWB MP P training.

EFR Response
EFR has implemented a training program in compliance with the SWBMPP Appendix l, Part l.l I (Spill
Reporting Requirements), as discussed below.
General Employee SWBMPP training will be provided to all employees as one of the topics addressed
each year during one of the quarterly employee refresher training sessions. All employees, other than
Mill Environmental Personnel, will be instructed regarding the Mill's requirement to comply with the
SWBMPP, and that their reporting responsibilities require them to alert Mill Environmental Personnel
immediately regarding any spills, leaks, failures of storage or process equipment, or abnormal flows from
ditches or impoundments. A copy of the outline for SWBMPP General Employee Training is provided in
Attachment 3. Documentation of training topics and attendance is maintained with existing quarterly
refresher training records. SWBMPP training will be conducted during the second quarter refresher
training each year, except 2012, when it will be conducted during the third quarter refresher training
session.
Mill Environmental Personnel will receive an additional level of SWBMPP training as well as the general
Employee SWBMPP Training. Mill Environmental Personnel will be trained to meet the requirements of
Part I.D.l0 of the Permit, and to perform the reporting required for reportable quantity ("RQ") spills, as
well as the internal documentation of non-RQ spills. A copy of the course outline and training calendar
for Environmental Staff Training has been provided in Attachment 4. EFR will maintain training records
for the Mill Environmental Personnel at the Mill. Environmental Staff SWBMPP Training will be
conducted in January ofeach year.
DRC Comment
3. Solvent Extraction (SX) Building Roof Drainage Improvements - Comments regarding needed
improvements to the SX building roof drain system have been ongoing since 2009. Per the 2012
inspection, issues related to the roofdrainage and discharges into the alternate feed circuit have
not been addressed. DUSA agrees to upgrade the SX building roof drainage to prevent potential
standing water on the ground within 60 calendar days of receipt of this letter. Specifically, DUSA
will provide appropriate drainage control for roof areas depicted in photograph 30 of the Memo
(north-west section of the building) and will provide documentation to DRC regardingfollow-up
actions undertaken.
EFR Response
As requested, EFR agrees to construct modifications to the SX building roof drainage within 60 days of
receipt of DRC's letter. EFR plans to install a concrete trench system to collect the water runoff from the
SX building roof and transfer it to the tailings cell area.
The roof edges of the Mill buildings in the SX area are subject to high winds. EFR expects that any
rainwater collection system built on the roof (such as a gutter and downspout) would be subject to the
same recurrent wind damage as currently affects other roof materials. Therefore EFR has chosen to
minimize construction of rooftop elements, in lieu of the proposed trench at ground level.
The trench will be designed large enough to ensure ease of access for sediment removal, and will be
constructed by October 9,2012 (within 60 days of EFR's receipt of DRC's inspection letter).

4. Based on DRC review of the DUSA May 4, 2012 letter "Response to Claricone Solution Spill" it
was noted that confirmation soil sampling was not conducted to ensure that all contaminated soil
had been removed. Excavation of contaminated material was based on visual examination and
gamma surveying (microR meter) only. DUSA will submit to DRC either:
A. A work plctn for the collection of confirmation soil samples to be collected ond analyzed
for appropriate radiological parameters and total uranium within 45 days from DUSA
receipt of this letter. The work plan will detail the techniques to be used for sample
collection, number and locations of samples to be collected, methods to be used for soils
analysis, and will propose confirmation sample concentration thresholds to be used for
the evaluation. DUSA will propose applicable concentration standards to be used for
radiological parameters (per applicable guidance/regulations); and will propose a study
evaluation to determine an appropriate background concentration for total uranium
within the restricted area of the Mill. The total uranium soil concentration threshold to
be used for confirmation samples will be based on 2 times the average measured
background concentrationsfor total uranium as determined through the work plan study,
or;
B. A conservative basis for a larger three dimensional area of potentially contaminated soil
due to the clmicone solution spill, in lieu of confirmation soil sampling, which will
include a calculated soil excavation volume (beyond the previous excavated soil volume).
DUSA will provide a Report which describes the justification for the calculated soil
volume and includes a surface map of the Mill and cross sections clearly depicting the
ultimate area of soil for excavation, removal and disposal (at site closure). DUSA will
provide a surety estimate, for Director review and approval, which includes line items forall work associated with excavation, removal and disposal of the proposed soil volume.
The Report and Surety Estimate will be submitted within 45 days from DUSA receipt oJ
this letter.
EFR Response
EFR proposes to produce a conservative estimate of potentially contaminated soil resulting from the
Claricone spill, and calculation of additional soil excavation volume to be removed at reclamation,
consistent with Item B, above. EFR will provide a Report which describes the justification for the
calculated soil volume and includes a surface map of the Mill and cross sections clearly depicting the
ultimate area of soil for excavation, removal and disposal (at site closure). EFR will provide a suretSr
estimate, for review and approval by the Director of the Division of Radiation Control, which includes
line items for all work associated with excavation, removal and disposal of the proposed soil volume. As
agreed to in our telephone conversation of August 28,2012, and confirmed by DRC's letter of August 30,
2012, EFR will provide the required report by October 26,2012.

PLAN FOR CHEMICALS AND PETROLEUM PRODUCIS
1O OBJECTIVE:
The objective of the Spill Prevention, Control, and Countermeasures (SPCC)
Plan is to serve as a site-specific guideline for the prevention of and
response to chemical and petroleum spills. The plan outlines spill potentials,
containment areas, and drainage characteristics of the White Mesa Mill site.
The plan addresses chemicalspill prevention, spill potentials, spill discovery,
and spill notification procedures. Spills are reportable if the spill leaves the
site. Ammonia is the only chemical (as vapor) that has the potentialto leave
the site. ln addition, chemical and petroleum spills will be reported in
accordance with applicable laws and regulations.
Figure 1.0, Mill Site Layout,shows a map of the mill site including the
locations of the chemical tanks on-site. Figure 2 shows the basins and
drainage ditch areas for the mill site. Table 1.0 is an organization chart for
Mill operations. Table 2.0 lists the reagent tanks and their respective
capacities. Table 3.0 lists the laboratory chemicals, their amounts, and their
reportable quantities. Table 4.0 lists the operations chemicals. Table 5.0
lists the chemicals in the reagent yard, their amounts, and their reportable
quantities. Table 6.0 lists the petroleum products and solvents on site.

Refer to Secfion 1.9 Spill lncident Notification for a list of personnel to be
notified in case of a spill. ln addition, an organizational chart is provided in
Figure 3.0.
DRAINAGE BASINS, PATHWAYS, AND DIVERSIONS:
4.0
The main drainage pathways are illustrated in Figure 2. The map shows
drainage basin boundaries, flow paths, constructed diversion ditches, tailing
cells, the spillway between Cell 2 and 3, dikes, berms, and other relevant
features. The white Mesa Mill is a"zero" discharge facility for process liquid
wastes. The mill area has been designed to ensure that all spills or leaks
from tanks will drain toward the lined tailing cells.
The tailings cells, in turn, are operated with sufficient freeboard (minimum of
three feet) to withstand 100% of the PMP (Probable Maximum Precipitation).
This allows for a maximum of 10 inches of rain at any given time.
DESCRIPTION OF BASINS:
4.2
.4.1
4.3
Precipitation and unexpected spills from the mill site are contained within
their prospective drainage basins. Overflow ultimately drains into one of the
four lined tailings cells.
Basin Al
Basin A1 is north of Cell 1-l and Diversion Ditch No. 1. The basin
contains 23 tributary acres, all of which drain into Westwater Creek.
Basin A2
Basin A2 contains all of Cell 1-l including an area south of the Diversion
Ditch No. 1. The basin covers 84 acres. Any overflow from this basin
would be contained within Cell 1-1.
Basin Bl
Basin B1 is north of the mill area. The basin contains 45.4 tributary
acres.
Overflow from this basin drains into a flood retention area by flowing
through Diversion Ditch No. 2. Diversion Ditch No. 2 drains into
Westwater Creek.
Basin 82
Basin 82 is northeast of the mill area and contains only 2.6 tributary
acres. Overflow from this basin would drain into Diversion Ditch No. 3.
Diversion Ditch No. 3 ultimately drains into Diversion Ditch No. 2.
4.4
4.5
4.6
4.7
4.8
4.9
5.0
Basin 83
Basin 83 contains most of the mill area, buildings, ore stockpiles, process
storage tanks, retention ponds, spill containment structures, pipelines,
and roadways. The normal direction of flow in this basin is from the
northwest to the southwest. Any overflow from this basin would drain into
Cell 1-1. The basin contains 64 acres. This basin has sufficient
freeboard to withstand 100% of the PMP (Probable Maximum
Precipitation). This allows 10 inches of rain for any given storm event.
Basin C
Basin C contains all of Cell 2. The basin consists of 80.7 acres. Areas in
this basin include earth stockpiles and the heavy equipment shop. The
direction of flow in this basin is to the southwest. All overflows in this
basin is channeled along the southern edge of the basin. Overflow then
flows into Cell 3 via the spillway from Cell 2 to Cell 3.
Basin D
Basin D contains all of Cell 3. This basin consists of 78.3 acres including
a portion of the slopes of the topsoil stockpile and random stockpile. The
basin contains all flows, including those caused by the PMF.
Basin E
Basin E contains Cell 4A and consists of 40 acres. All anticipated flows
including those caused by the PMF will be contained within the basin and
will flow directly into Cell 4,A.
Basin F
Basin F will contain Cell 48, if and when constructed. The area consists
of 44 acres at a relatively low elevation. Direction of flow in this basin is
towards the southwest.
POTENTIAL CHEMICAL SPILL SOURCES AND SPILL
CONTAINMENT
5.1 Reagent Tanks (Tank list included in Table 2.0)
Ammonia
The ammonia storage tanks consist of two tanks with a capacity of
31,409 gallons each. The tanks are located southeast of the Mill building.
Daily monitoring of the tanks for leaks and routine integrity inspections will be
conducted to minimize the hazard associated with ammonia. The reportable
quantity for an ammonia spill is 7 gallons.
5.2
5.3
Ammonia spills should be treated as gaseous. Ammonia vapors will be
monitored closely to minimize the hazard associated with inhalation. lf
vapors are detected, efforts will be made to stop or repair the leak
expeditiously. Ammonia is the only chemical (as vapor) that has the potential
to leave the site.
Ammonia Meta-Vanadate
Ammonia meta-vanadate is present in the SX building as the process
solutions move through the circuit to produce the vanadium end product.
Spills would be contained in the process sump within the SX building. The
reportable spill quantity for ammonia meta-vanadate is 1,000 pounds.
5.4 Caustic Storage (Sodium Hydroxide)
5.5
The caustic storage tank is located on a splash pad on the northwest corner
of the SX building. The tank has a capacity of 19,904 gallons. The tank
supports are mounted on a concrete curbed catchment pad which directs
spills into the sand filter sump in the northwest corner of the SX building.
The reportable spill quantity for sodium hydroxide is 85 gallons.
Sodium Carbonate (Soda Ash)
The soda ash solution tank has a capacity of 16,921gallons and is located in
the northeast corner of the SX building. The smaller soda ash shift tank has
a capacity of 8,530 gallons and is located in the SX building. Spills will be
diverted into the boiler area, and would ultimately drain into Cell 1-1. There is
no reportable spill quantity associated with sodium carbonate.
Sodium Chlorate
Sodium chlorate tanks consist of two fiberglass tanks located within a dike
east of the SX building. The larger tank is used for dilution purposes and has
a maximum capacity of 17 ,700 gallons. The smaller tank serves as a
storage tank and has a capacity of 10,500 gallons. Daily monitoring of the
tanks for leaks and integrity inspections will be conducted to minimize the
hazard associated with sodium chlorate.
Sodium chlorate that has dried and solidified becomes even more of a safety
hazard due to its extremely flammable nature. The reportable spill quantity
for sodium chlorate is 400 gallons.
Sulfuric Acid
The sulfuric acid storage tanks consist of one large tank with the capacity of
1,600,000 gallons and two smaller tanks with capacities of 269,160 gallons
each.
The large tank is located in the northwest corner of mill area basin 83 and is
primarily used for acid storage and unloading. The tank support for the large
tank is on a mound above a depression which would contain a significant
spill. All flows resulting would be channeled to Cell 1-1. The tank is equipped
5.6
5.7
with a high level audible alarm which sounds prior to tank overflows. A
concrete spill catchment with a sump in the back provides added
containment around the base of the tank. However, the catchment basin
would not be able to handle a major tank failure such as a tank rupture. The
resulting overflow would flow towards Cell 1-1.
The two smaller storage tanks are located within an equalvolume spill
containment dike east of the mill building. The tanks are not presently in
use, but are equipped with high level audible alarms.
The reportable spill quantity for sulfuric acid is 65 gallons.
5.8 Vanadium Pentoxide
Vanadium pentoxide is produced when vanadium is processed through the
drying and fusing circuits and is not present in the vanadium circuit until after
the deammoniator. Efforts will be made to minimize leaks or line breaks that
may occur in processes in the circuit that contain vanadium pentoxide.
Special care will be taken in the transportation of this chemical. The
reportable spill quantity for vanadium pentoxide is 1000 pounds.
5.9 Kerosene (Organic)
The kerosene storage area is located in the central mill yard and has a
combined capacity ol 10,152 gallons in three tanks. Any overflow from these
three tanks would flow around the south side of the SX building and then into
Cell 1-1. These tanks have drain valves which remain locked unless
personnel are supervising draining operations. The reportable spill quantity
for kerosene is 100 gallons.
5.{0 Used/ Waste Oil
Used/ Waste oil for parts washing is located north of the maintenance shop
in a tank and has a capacity of 5,000 gallons. The tank is contained within a
concrete containment system. Ultimate disposal of the used oil is to an EPA
permitted oil recycler. Any oil escaping the concrete containment system will
be cleaned up. Soil contaminated with used oilwill be excavated and
disposed of in Cell 2.
6.0 POTENTIAL PETROLEUM SPILL SOURCES AND
CONTAINMENT
6.1 Petroleum Tanks
6.1.1 Diesel
There are two diesel storage tanks located north of the mill building. The
tanks have capacities of 250 gallons each. One of the diesel tanks is for the
emergency generator. The other tank is located in the pumphouse on an
6.2
6.2.1
6.2.2
6.2.3
6.2.4
elevated stand. Spillage from either tank would ultimately flow into Cell 1-1.
The reportable spill quantity for diesel is 100 gallons. The spill is also
reportable if the spill has the potential for reaching any nearby surface waters
or ground waters.
Aboveground Fuel Pump Tanks
Diesel
The diesel tank is located on the east boundary of Basin 83 and has a
capacity of 6,000 gallons. The tank is contained within a concrete catchment
pad. The reportable spill quantity for diesel is 100 gallons. A diesel spill is
also reportable if the spill has the potential for reaching any surface waters or
ground waters.
Unleaded Gasoline
The unleaded gasoline tank is located next to the diesel tank. The unleaded
gasoline tank has a capacity of 3,000 gallons and is contained within the
same containment system as the diesel tank. Spills having the potential for
reaching any surface waters or ground waters will need to be reported. The
reportable spill quantity for unleaded gasoline is 100 gallons.
Pump Station
Both the diesel and the unleaded gasoline tanks will be used for refueling
company vehicles used around the mill site. The pump station is equipped
with an emergency shut-off device in case of overflow during fueling. ln
addition, the station is also equipped with a piston leak detector and
emergency vent. Check valves are present along with a tank monitor
console with a leak detection system. The catchment is able to handle a
complete failure of one tank. However, if both tanks failed the concrete
catchment pad would not be able to contain the spill. ln this case, a
temporary berm would need to be constructed. Absorbent diapers or floor
sweep would be used in an effort to limit and contain the spill. The soil would
have to be cleaned up and placed in the authorized dump in Cell 2.
Truck Unloading
ln the event of a truck accident resulting in an overturned vehicle in the mill
area, proper reporting and containment procedures will be followed when
warranted, such as when oil or diesel fuel is spilled. Proper clean-up
procedures will be followed to minimize or limit the spill. The spill may be
temporarily bermed or localized with absorbent compounds. Any soils
contaminated with dieselfuel or oilwill be cleaned up and placed in Cell 2.
7.0 SPILL DISCOVERY AND REMEDIAL ACTION
Once a chemical or petroleum spill has been detected, it is important to take
measures to limit additional spillage and contain the spill that has already
occurred. Chemical or petroleum spills will be handled as follows:
The Shift Foreman will direct efforts to shut down systems, if
possible, to limit further release.
The Shift Foreman will also secure help if operators are requiring
additional assistance to contain the spill.
The Shift Foreman is also obligated to initiate reporting procedures.
Once control measures have begun and personal danger is
minimized, the Shift Foreman will notify the Production
Superintendent, Maintenance Superintendent, or Mill Manager.
The Production or Maintenance Superintendent will notify the Mill
Manager, who in turn will notify the Department Head of EA/HS
and/or the Environmental Coordinator.
The Mill Manager will assess the spill and related damage and direct
remedial actions. The corrective actions may include repairs, clean-
up, disposal, and company notifications. Government notifications
may be necessary in some cases.
lf a major spill continues uncontrolled, these alternatives will be considered:
1. Construct soil dikes or a pit using heavy equipment.
2. Construct a diversion channel into an existing pond.
3. Start pumping the spill into an existing tank or pond.
4. Plan further clean-up and decontamination measures.
8.0 SPILL INCIDENT NOTIFICATION
8.1 External Notification
For chemical and petroleum spills that leave the site, the following agencies
should be notified:
1. EPA National Response Center 1-800-424-8802
2. US Nuclear Regulatory Commission 301/816-5100
3. State of Utah 801/538-7200
ln case of a tailings dam failure, contact the following agencies:

PLAN FOR CHEMICALS AND PETROLEUM PRODUCIS
1+O OBJECTIVE:
The objective of the Spill Prevention, Control, and Countermeasures (SPCC)
Plan is to serve as a site-specific guideline for the prevention of and
response to chemical and petroleum spills. The plan outlines spill potentials,
containment areas, and drainage characteristics of the White Mesa Mill site.
The plan addresses chemicalspill prevention, spill potentials, spilldiscovery,
and spill notification procedures. Spills are reportable if the spill leaves the
site. Ammonia is the only chemical (as vapor) that has the potential to leave
the site. ln addition, chemical and petroleum spills will be reported in
accordance with applicable laws and regulations.
Figure 1.0, Mill Site Layout -l/lapshows a map of the mill site including the
locations of the chemical tanks on-site. Figure 2 shows the basins and
drainage ditch areas for the mill site. Table 1.0 is an organization chart for
Mill operations. Table 2.0 lists the reagent tanks and their respective
capacities. Table 3.0 lists the laboratory chemicals, their amounts, and their
reportable quantities. Table 4.0 lists the operations chemicals. Table 5.0
lists the chemicals in the reagent yard, their amounts, and their reportable
quantities. Table 6.0 lists the petroleum products and solvents on site.

DRAINAGE BASINS, PATHWAYS, AND DIVERSIONS:
u.0
The main drainage pathways are illustrated in Plat+Eig-ure {$2. The map
shows drainage basin boundaries, flow paths, constructed diversion ditches,
tailing cells, the spillway between Cell2 and 3, dikes, berms, and other
relevant features. The White Mesa Mill is a"zero" discharge facility for
process liquid wastes. The mill area has been designed to ensure that all
spills or leaks from tanks will drain toward the lined tailing cells.
The tailings cells, in turn, are operated with sufficient freeboard (minimum of
three feet) to withstand 100% of the PMP (Probable Maximum Precipitation).
This allows for a maximum of 10 inches of rain at any given time.
DESCRIPTION OF BASINS:
+.4.1
4.2
M.3
Precipitation and unexpected spills from the mill site are contained within
their prospective drainage basins. Overflow ultimately drains into one of the
four lined tailings cells.
Basin A1
Basin A1 is north of Cell 1-l and Diversion Ditch No. 1. The basin
contains 23 tributary acres, all of which drain into Westwater Creek.
Basin A2
Basin ,A2 contains all of Cell 1-l including an area south of the Diversion
Ditch No. 1. The basin covers 84 acres. Any overflow from this basin
would be contained within Cell 1-1.
Basin Bl
Basin B1 is north of the mill area. The basin contains 45.4 tributary
acres.
Overflow from this basin drains into a flood retention area by flowing
through Diversion Ditch No. 2. Diversion Ditch No. 2 drains into
Westwater Creek.
Basin 82
Basin 82 is northeast of the mill area and contains only 2.6 tributary
acres. Overflow from this basin would drain into Diversion Ditch No. 3.
Diversion Ditch No. 3 ultimately drains into Diversion Ditch No. 2.
u.4
M.5 Basin 83
#.6
Basin 83 contains most of the mill area, buildings, ore stockpiles, process
storage tanks, retention ponds, spill containment structures, pipelines,
and roadways. The normal direction of flow in this basin is from the
northwest to the southwest. Any overflow from this basin would drain into
Cell 1-1. The basin contains 64 acres. This basin has sufficient
freeboard to withstand 100% of the PMP (Probable Maximum
Precipitation). This allows 10 inches of rain for any given storm event.
Basin G
Basin C contains all of Cell 2. The basin consists of 80.7 acres. Areas in
this basin include earth stockpiles and the heavy equipment shop. The
direction of flow in this basin is to the southwest. All overflows in this
basin is channeled along the southern edge of the basin. Overflow then
flows into Cell 3 via the spillway from Cell 2 to Cell 3.
Basin D
Basin D contains all of Cell 3. This basin consists of 78.3 acres including
a portion of the slopes of the topsoil stockpile and random stockpile. The
basin contains all flows, including those caused by the PMF.
Basin E
Basin E contains Cell 4A and consists of 40 acres. All anticipated flows
including those caused by the PMF will be contained within the basin and
will flow directly into Cell4A.
Basin F
Basin F will contain Cell 48, if and when constructed. The area consists
of 44 acres at a relatively low elevation. Direction of flow in this basin is
towards the southwest.

Reagent Tanks (Tank list included in Table 2.0)
Ammonia
The ammonia storage tanks consist of two tanks with a capacity of
31,409 gallons each. The tanks are located southeast of the Mill building.
Daily monitoring of the tanks for leaks and routine integrity inspections will be
conducted to minimize the hazard associated with ammonia. The reportable
quantity for an ammonia spill is 7 gallons.
+5.3
+5.4
+5.5
+5.6
+5.7
Ammonia spills should be treated as gaseous. Ammonia vapors will be
monitored closely to minimize the hazard associated with inhalation. !f
vapors are detected, etforts will be made to stop or repair the leak
expeditiously. Ammonia is the only chemical (as vapor) that has the potential
to leave the site.
Ammonia Meta-Vanadate
Ammonia meta-vanadate is present in the SX building as the process
solutions move through the circuit to produce the vanadium end product.
But; the primary feeue will be en the transpertation ef this ehemiealspills
would be contained in the process sump within the SX buildino. The
reportable spill quantity for ammonia meta-vanadate is 1,000 pounds.
Caustic Storage (Sodium Hydroxide)
The caustic storage tank is located on a splash pad on the northwest corner
of the SX building. The tank has a capacity of 19,904 gallons. The tank
supports are mounted on a concrete curbed catchment pad which directs
spills into the sand filter sump in the northwest corner of the SX building.
The reportable spill quantity for sodium hydroxide is 85 gallons.
Sodium Carbonate (Soda Ash)
The soda ash solution tank has a capacity of 16,921 gallons and is located in
the northeast corner of the SX building. The smaller soda ash shift tank has
a capacity of 8,530 gallons and is located in the SX building. Spills will be
diverted into the boiler area, and would ultimately drain into Cell 1-1. There is
no reportable spill quantity associated with sodium carbonate.
Sodium Chlorate
Sodium chlorate tanks consist of two fiberglass tanks located within a dike
east of the SX building. The larger tank is used for dilution purposes and has
a maximum capacity of 17,700 gallons. The smaller tank serves as a
storage tank and has a capacity of 10,500 gallons. Daily monitoring of the
tanks for leaks and integrity inspections will be conducted to minimize the
hazard associated with sodium chlorate.
Sodium chlorate that has dried and solidified becomes even more of a safety
hazard due to its extremely flammable nature. The reportable spill quantity
for sodium chlorate is 400 gallons.
Sulfuric Acid
The sulfuric acid storage tanks consist of one large tank with the capacity of
1,600,000 gallons and two smaller tanks with capacities of 269,160 gallons
each.
The large tank is located in the northwest corner of mill area basin 83 and is
primarily used for acid storage and unloading. The tank support for the large
tank is on a mound above a depression which would contain a significant
+5.8
spill. Allflows resulting would be channeled to Cell 1-1. The tank is equipped
with a high level audible alarm which sounds prior to tank overflows. A
concrete spill catchment with a sump in the back provides added
containment around the base of the tank. However, the catchment basin
would not be able to handle a major tank failure such as a tank rupture. The
resulting overflow would flow towards Cell 1-1.
The two smaller storage tanks are located within an equal volume spill
containment dike east of the mill building. The tanks are not presently in
use, but are equipped with high level audible alarms.
The reportable spill quantity for sulfuric acid is 65 gallons.
Vanadium Pentoxide
Vanadium pentoxide is produced when vanadium is processed through the
drying and fusing circuits and is not present in the vanadium circuit until after
the deammoniator. Efforts will be made to minimize leaks or line breaks that
may occur in processes in the circuit that contain vanadium pentoxide.
Special care will be taken in the transportation of this chemical. The
reportable spill quantity for vanadium pentoxide is 1000 pounds.
+5.9 Kerosene (Organic)
The kerosene storage area is located in the central mill yard and has a
combined capacity of 10,152 gallons in three tanks. Any overflow from these
three tanks would flow around the south side of the SX building and then into
Cell 1-1. These tanks have drain valves which remain locked unless
personnel are supervising draining operations. The reportable spillquantity
for kerosene is 100 gallons.
+5..1qs Used/ Waste Oil
Used/ Waste oil for parts washing is located north of the maintenance shop
in a tank and has a capacity of 5,000 gallons. The tank is contained within a
concrete containment system. Ultimate disposal of the used oil is to an EPA
permitted oil recycler. Any oil escaping the concrete containment system will
be cleaned up. Soil contaminated with used oilwill be excavated and
disposed of in Cell 2.

+97.1.t Diesel
There are two diesel storage tanks located north of the mill building. The
tanks have capacities of 250 gallons each. One of the diesel tanks is for the
emergency generator. The other tank is located in the pumphouse on an
elevated stand. Spillage from either tank would ultimately flow into Cell 1-1.
The reportable spill quantity for diesel is 100 gallons. The spill is also
reportable if the spill has the potential for reaching any nearby surface waters
or ground waters.
1,87.2 Aboveground Fuel Pump Tanks
1&7.2.1
+.97.2.2
Diesel
The dieseltank is located on the east boundary of Basin 83 and has a
capacity of 6,000 gallons. The tank is contained within a concrete catchment
pad. The reportable spill quantity for diesel is 100 gallons. A diesel spill is
also reportable if the spill has the potential for reaching any surface waters or
ground waters.
Unleaded Gasoline
The unleaded gasoline tank is located next to the dieseltank. The unleaded
gasoline tank has a capacity of 3,000 gallons and is contained within the
same containment system as the dieseltank. Spills having the potential for
reaching any surface waters or ground waters will need to be reported. The
reportable spill quantity for unleaded gasoline is 100 gallons.
+.91.2.3 Pump Station
Both the diesel and the unleaded gasoline tanks will be used for refueling
company vehicles used around the mill site. The pump station is equipped
with an emergency shut-off device in case of overflow during fueling. ln
addition, the station is also equipped with a piston leak detector and
emergency vent. Check valves are present along with a tank monitor
console with a leak detection system. The catchment is able to handle a
complete failure of one tank. However, if both tanks failed the concrete
catchment pad would not be able to contain the spill. ln this case, a
temporary berm would need to be constructed. Absorbent diapers or floor
sweep would be used in an effort to limit and contain the spill. The soilwould
have to be cleaned up and placed in the authorized dump in Cell 2.
+.07. 2.4T ruck Un loadin g
ln the event of a truck accident resulting in an overturned vehicle in the mill
area, proper reporting and containment procedures will be followed when
warranted, such as when oil or diesel fuel is spilled. Proper clean-up
procedures will be followed to minimize or limit the spill. The spill may be
temporarily bermed or localized with absorbent compounds. Any soils
contaminated with diesel fuel or oil will be cleaned up and placed in Cell 2.
+.7.08 SPILL DISCOVERY AND REMEDIAL ACTION
Once a chemical or petroleum spill has been detected, it is important to take
measures to limit additional spillage and contain the spill that has already
occurred. Chemical or petroleum spills will be handled as follows:
The Shift Foreman will direct efforts to shut down systems, if
possible, to limit further release.
The Shift Foreman will also secure help if operators are requiring
additional assistance to contain the spill.
The Shift Foreman is also obligated to initiate reporting procedures.
Once control measures have begun and personal danger is
minimized, the Shift Foreman will notify the Production
Superintendent, Maintenance Superintendent, or Mill Manager.
The Production or Maintenance Superintendent will notify the Mill
Manager, who in turn will notify the Department Head of EA/HS
and/or the Environmental Coordinator.
The Mill Manager will assess the spill and related damage and direct
remedial actions. The corrective actions may include repairs, clean-
up, disposal, and company notifications. Government notifications
may be necessary in some cases.
lf a major spill continues uncontrolled, these alternatives will be considered:
1. Construct soil dikes or a pit using heavy equipment.
2. Construct a diversion channel into an existing pond.
3. Start pumping the spill into an existing tank or pond.
4. Plan further clean-up and decontamination measures.
+8.09 SPILL INCIDENT NOTIFICATION

Revision 1.5: September 2012
1.0 INTRODUCTION/PI]RPOSE
Energy Fuels Resources (USA) Inc. ("EFR") operates the White Mesa Uranium Mill ("the Mill)
in Blanding, Utah. The Mill is a net water consumer, and is a zero-discharge facility with respect
to water effluents. That is, no water leaves the Mill site because the Mill has:. no outfalls to public stormwater systems,. no surface runoff to public stormwater systems,. no discharges to publicly owned treatment works ("POTWs"), and. no discharges to surface water bodies.
The State of Utah issued Groundwater Discharge Permit No. UGW370004 to EFR on March 8,
2005. As a part of compliance with the Permit, EFR is required to submit a Stormwater Best
Management Practices Plan ("BMPP") to the Executive Secretary of the Division of Radiation
Control, Utah Department of Environmental Quality. This BMPP presents operational and
management practices to minimize or prevent spills of chemicals or hazardous materials, which
could result in contaminated surface water effluents potentially impacting surface waters or
ground waters through runoff or discharge connections to stormwater or surface water drainage
routes. Although the Mill, by design, cannot directly impact stormwater, surface water, or
groundwater, the Mill implements these practices in a good faith effort to minimize all sources of
pollution at the site.
Page 2
Best Management Practices Plan
Revision 1.5: September 2012
2.0 SCOPE
This BMPP identifies practices to prevent spills of chemicals and hazardous materials used in
process operations, laboratory operations, and maintenance activities, and minimize spread of
particulates from stockpiles and tailings management areas at the Mill. Storage of ores and
alternate feeds on the ore pad, and containment of tailings in the Mill tailings impoundment
system are not considered "spills" for the purposes of this BMPP.
The Mill site was constructed with an overall grade and diversion ditch system designed to
channel all surface runoff, including precipitation equivalent to a Probable Maximum
Precipitation/Probable Maximum Flood ("PMP/PMF") storm event, to the tailings management
system. In addition, Mill tailings, all other process effluents, all solid waste and debris (except
used oil and recyclable materials), and spilled materials that cannot be recovered for reuse are
transferred to one or more of the tailings cells in accordance with the Mill's NRC license
conditions. All of the process and laboratory building sinks, sumps, and floor drains are tied to
the transfer lines to the tailings impoundments. A site map of the Mill is provided in Figure 1. A
sketch of the site drainage basins is provided in Figure 2.
As a result, unlike other industrial facilities, whose spill management programs focus on
minimizing the introduction of chemical and solid waste and wastewater into the process sewers
and storm drains, the Mill is permitted by NRC license to manage some spills via draining or
wash down to the process sewers, and ultimately the tailings system. However, as good
environmental management practice, the Mill attempts to minimize:
1. the number and size of material spills, and2. the amount of unrecovered spilled material and wash water that enters the process sewers
after a spill cleanup.
Section 4.0 itemizes the practices in place at the Mill to meet these objectives.
This BMPP addresses the management of stormwater, and the prevention of spills of chemicals
and hazardous materials, at the Mill site. Detailed requirements and methods for management,
recordkeeping, and documentation of hazardous material spills are addressed separately in the
EFR White Mesa Mill Spill Prevention, Control and Counterrneasures ("SPCC") Plan, the
Emergency Response Plan ("ERP") , and the housekeeping procedures incorporated in the White
Mesa Mill Standard Operating Procedures ("SOPs").

Revision 1.5: September 2012
4.0 BEST MAIIAGEMENT PRACTICES
A summary list and inventory of all liquid and solid materials managed at the Mill is provided in
Tables 2 through 5.
4.1 General Management Practices Applicable to All Areas
4.1.1 Keep Potential Pollutants from Contact with Soil, and Surface Water:
o Store hazardous materials and other potential pollutants in appropriate containers.o Label the containers.o Keep the containers covered when not in use.
4.1.2 Keep Potential Pollutants from Contact with Precipitation
o Store bulk materials in covered tanks or drums.
o Store jars, bottle, or similar small containers in buildings or under covered areas.. Replace or repair broken dumpsters and bins.
o Keep dumpster lids and large container covers closed when not in use (to keep
precipitation out).
4.1.3 Keep Paved Areas from Becoming Pollutant Sources
o Sweep paved areas regularly, and dispose of debris in the solid waste dumpsters or
tailings area as appropriate.
4.1.4 Inspection and Maintenance of Diversion Ditches and Drainage Channels within the
Process and Reagent Storage Area
o Diversion ditches, drainage channels and surface water control structures in and around
the Mill area will be inspected at least monthly in accordance with the regularly
scheduled inspections required by Groundwater Discharge Permit No. UGW370004, and
by product Materials License #UT1900479. Areas requiring maintenance or repair, such
as excessive vegetative growth, channel erosion or pooling of surface water runoff, will
be reported to site management and maintenance departments for necessary action to
repair damage or perform reconstruction in order for the control feature to perform as
intended. Status of maintenance or repairs will be documented during follow up
inspections and additional action taken ifnecessary.
4.1.5 Recycle Fluids Whenever Possible:
. When possible, select automotive fluids, solvents, and cleaners that can be recycled or
reclaimed
o When possible, select consumable materials from suppliers who will reclaim empty
containers.o Keep spent fluids in properly labeled, covered containers until they are picked up for
recycle or transferred to the tailings area for disposal.
Page 5
Best Management Practices Plan
Revision 1.5: September 2012
4.2 Management Practices for Process and Laboratory Areas
4.2.1 Clean Up Spitls Properly
. Clean up spills with dry cleanup methods (absorbents, sweeping, collection drums) instead of
water whenever possible.
. Clean spills of stored reagents or other chemicals immediately after discovery.
o (Groundwater Discharge Permit No. UGW370004, Section I.D.l0.c.)o Recover and re-use spilled material whenever possible.
o Keep supplies of rags, sorbent materials (such as cat liffer), spill collection drums, and personnel
protective equipment ("PPE") near the areas where they may be needed for spill response.
. If spills must be washed down, use the minimum amount of water needed for effective cleanup.
4.2.2 Protect Materials Stored Outdoors
o If drummed feeds or products must be stored outdoors, store them in covered or diked areas when
possible.
o If drummed chemicals must be stored outdoors, store them in covered or diked areas when
possible.
o Make sure drums and containers stored outdoors are in good condition and secured against wind
or leakage. Place any damaged containers into an overpack drum or second container.
4.2.3 Management
. When possible, recycle and reuse water from flushing and pressure testing equipment. When
possible, wipe down the outsides of containers instead of rinsing them off in the sink.. When possible, wipe down counters and work surfaces instead of hosing or rinsing them off to
sinks and drain
4.2.4 MaterialsManagement
o Purchase and inventory the smallest amount of laboratory reagent necessary.o Do not stock more of a reagent than will be used up before its expiration date.
o All new construction of reagent storage facilities will include secondary containment which shall
control and prevent any contact ofspilled reagents, or otherwise released
. reagent or product, with the ground surface. (Groundwater Discharge Permit No.o UGW370004, Section I.D.3.g.)

Revision 1.5: September 2012
4.3 Management Practices for Maintenance Activities
4.3.1 Keep a Clean Dry Shop
o Sweep or vacuum shop floors regularly.
o Designate specific areas indoors for parts cleaning, and use cleaners and solvents only in those
areas.o Clean up spills promptly. Don't let minor spills spread.
o Keep supplies of rags, collection containers, and sorbent material near each work area where they
are needed.
o Store bulk fluids, waste fluids, and batteries in an area with secondary containment (double drum,
drip pan) to capture leakage and contain spills.
4.3.2 Manage Vehicle Fluids
o Drain fluids from leaking or wrecked/damaged vehicles and equipment as soon as possible. Use
drip pans or plastic tarps to prevent spillage and spread of fluids.o Promptly contain and transfer drained fluids to appropriate storage area for reuse, recycle, or
disposal.
o Recycle automotive fluids, if possible, when their useful life is finished.
4.3.3 Use Controls During Paint Removal
o Use drop cloths and sheeting to prevent windborne contamination from paint chips and
sandblasting dust.o Collect, contain, and transfer, as soon as possible, accumulated dusts and paint chips to a disposal
location in the tailings area authorized to accept waste materials from maintenance or
construction activities.
4.3.4 Use Controls During Paint Application and Cleanup
o Mix and use the right amount of paint for the job. Use up one container before opening a second
one.o Recycle or reuse leftover paint whenever possible.
o Never clean brushes or rinse or drain paint containers on the ground (paved or unpaved).o Clean brushes and containers only at sinks and stations that drain to the process sewer to the
tailings system.o Paint out brushes to the extent possible before water washing (water-based paint) or solvent
rinsing (oil-based paint).o Filter and reuse thinners and solvent whenever possible). Contain solids and unusable excess
liquids for transfer to the tailings area

Revision 1.5: September 2012
4.4 Management Practices for Ore Pad, Tailings Area, and Heavy Equipment
Detailed instructions for ore unloading, dust suppression, and tailings management are provided
in the Mill SOPs.
4.4.1 Wash Down Vehicles and Equipment in Proper Areas
4.4.2
Wash down trucks, trailers, and other heavy equipment only in areas designated for this purpose
(such as wash down pad areas and tile truck wash station).
At the truck wash station, make sure the water collection and recycling system is working before
turning on water sprays.
Manage Stockpiles to Prevent Windborne Contamination
Water spray the ore pad and unpaved areas at appropriate frequency in accordance with Mill
SOPs.
Water spray stockpiles as required by opacity standards or weather conditions.
Don't over-water. Keep surfaces moist but minimize runoff water.
Keep Earthmoving Activities from Becoming Pollutant Sources
Schedule excavation, grading, and other earthmoving activities when extreme dryness and high
winds will not be a factor (to prevent the need for excessive dust suppression).
Remove existing vegetation only when absolutely necessary.
Seed or plant temporary vegetation for erosion control on slopes.

1.0 INTRODUCTION/PIIRPOSE
(USA) €orpl[g. ("D[IS+EFR") operates the White Mesa
Uranium Mill ("the Mill) in Blanding, Utah. The Mill is a net water consumer, and is azero-
discharge facility with respect to water effluents. That is, no water leaves the Mill site because the
Mill has:o no outfalls to public stormwater systems,. no surface runoffto public stormwater systems,. no discharges to publicly owned treatment works ("POTWs"), and. no discharges to surface water bodies.
The State of Utah issued Groundwater Discharge Permit No. UGW370004 to DEIS,IEE& on
March 8, 2005. As a part of compliance with the Permit, DUS+EER is required to submit a
Stormwater Best Management Practices Plan ("BMPP") to the Executive Secretary of the
Division of Radiation Control, Utah Department of Environmental Quality. This BMPP presents
operational and management practices to minimize or prevent spills of chemicals or hazardous
materials, which could result in contaminated surface water effluents potentially impacting
surface waters or ground waters through runoffor discharge connections to stormwater or surface
water drainage routes. Although the Mill, by design, cannot directly impact stormwater, surface
water, or groundwater, the Mill implements these practices in a good faith effort to minimize all
sources of pollution at the site.

Best Management Practices Plan
Revision l.5a: eetebe+SggLg4bsl 20 12+
2.0 SCOPE
This BMPP identifies practices to prevent spills of chemicals and hazardous materials used in
process operations, laboratory operations, and maintenance activities, and minimize spread of
particulates from stockpiles and tailings management areas at the Mill. Storage of ores and
alternate feeds on the ore pad, and containment of tailings in the Mill tailings impoundment
system are not considered "spills" for the purposes of this BMPP.
The Mill site was constructed with an overall grade and diversion ditch system designed to
channel all surface runoff, including precipitation equivalent to a Probable Maximum
Precipitation/Probable Maximum Flood ('PMP/PMF") storm event, to the tailings management
system. In addition, Mill tailings, all other process effluents, all solid waste and debris (except
used oil and recyclable materials), and spilled materials that cannot be recovered for reuse are
transferred to one or more of the tailings cells in accordance with the Mill's NRC license
conditions. All of the process and laboratory building sinks, sumps, and floor drains are tied to
the transfer lines to the tailings impoundments. A site map of the Mill is provided in Figure l. A
sketch of the site drainage basins is provided in Figure 2.
As a result, unlike other industrial facilities, whose spill management programs focus on
minimizing the introduction of chemical and solid waste and wastewater into the process sewers
and storm drains, the Mill is permitted by NRC license to manage some spills via draining or
wash down to the process sewers, and ultimately the tailings system. However, as good
environmental management practice, the Mill attempts to minimize:
1. the number and size of material spills, and2. the amount of unrecovered spilled material and wash water that enters the process sewers
after a spill cleanup.
Section 4.0 itemizes the practices in place at the Mill to meet these objectives.
This BMPP addresses the management of stormwater. and the prevention of spills of chemicals
and hazardous materials. at the Mill site. Detailed rRequirements and methods for management,
recordkeeping, and documentation of hazardous material spills are addressed separately in the
DUS+EEB White Mesa Mill Spill Prevention, Control and Counterneasures ("SPCC") Plan, the
Emergency Response Plan ("ERp")q , and the housekeeping procedures incorporated in the White
MesaMillStandardoperatingProcedures(''SoPs'').

4.0 BEST MANAGEMENT PRACTICES
A summary list and inventory of all liquid and solid materials managed at the Mill is provided in
Tables 2 through 5.
4.1 General Management Practices Applicable to All Areas
4.1.1 Keep Potential Pollutants from Contact with Soil, and Surface Water:
o Store hazardous materials and other potential pollutants in appropriate containers.o Label the containers.o Keep the containers covered when not in use.
4.1.2 Keep Potential Pollutants from Contact with Precipitation
o Store bulk materials in covered tanks or drums.o Store jars, bottle, or similar small containers in buildings or under covered areas.. Replace or repair broken dumpsters and bins.o Keep dumpster lids and large container covers closed when not in use (to keep
precipitation out).
4.1.3 Keep Paved Areas from Becoming Pollutant Sources
o Sweep paved areas regularly, and dispose of debris in the solid waste dumpsters or
tailings area as appropriate.
4.1.4 Inspection and Maintenance of Diversion Ditches and Drainage Channels within the
Process and Reagent Storage Area
o Diversion ditches, drainage channels and surface water control stnrctures in and around
the Mill area will be inspected at least monthly in accordance with the regularly
scheduled inspections required by Groundwater Discharge Permit No. UGW370004, and
by product Materials License #UT1900479. Areas requiring maintenance or repair, such
as excessive vegetative growth, channel erosion or pooling of surface water runoff, will
be reported to site management and maintenance departments for necessary action to
repair damage or perform reconstruction in order for the control feature to perform as
intended. Status of maintenance or repairs will be documented during follow up
inspections and additional action taken if necessary.
4.1.5 Recycle Fluids Whenever Possible:
o When possible, select automotive fluids, solvents, and cleaners that can be recycled or
reclaimed
o When possible, select consumable materials from suppliers who will reclaim empty
containers.o Keep spent fluids in properly labeled, covered containers until they are picked up for
recycle or transferred to the tailings area for disposal.

4.2 Management Practices for Process and Laboratory Areas
4.2.1 Clean Up Spills Properly
o Clean up spills with dry cleanup methods (absorbents, sweeping, collection drums) instead of
water whenever possible.o Clean spills of stored reagents or other chemicals immediately after discovery.o (Groundwater Discharge Permit No. UGW370004, Section I.D.l0.c.)o Recover and re-use spilled material whenever possible.o Keep supplies of rags, sorbent materials (such as cat litter), spill collection drums, and personnel
protective equipment ('PPE") near the areas where they may be needed for spill response.. If spills must be washed down, use the minimum amount of water needed for effective cleanup.
4.2.2 Protect Materials Stored Outdoors
o If drummed feeds or products must be stored outdoors, store them in covered or diked areas when
possible.
o If drummed chemicals must be stored outdoors, store them in covered or diked areas when
possible.
o Make sure drums and containers stored outdoors are in good condition and secured against wind
or leakage. Place any damaged containers into an overpack drum or second container.
4.2.3 Management
o When possible, recycle and reuse water from flushing and pressure testing equipment. When
possible, wipe down the outsides of containers instead of rinsing them off in the sink.o When possible, wipe down counters and work surfaces instead of hosing or rinsing them off to
sinks and drain
4.2.4 MaterialsManagement
o Purchase and inventory the smallest amount of laboratory reagent necessary.o Do not stock more of a reagent than will be used up before its expiration date.o All new construction of reagent storage facilities will include secondary containment which shall
control and prevent any contact ofspilled reagents, or otherwise releasedo reaBont or product, with the ground surface. (Groundwater Discharge Permit No.o UGW370004, Section I.D.3.g.)

Revision I .5a: eeteberSgglglqbgl20 I 2+
4.3 Management Practices for Maintenance Activities
4.3.1 Keep a Clean Dry Shop
o Sweep or vacuum shop floors regularly.o Designate specific areas indoors for parts cleaning, and use cleaners and solvents only in those
areas.o Clean up spills promptly. Don't let minor spills spread.
o Keep supplies of rags, collection containers, and sorbent material near each work area where they
are needed.
o Store bulk fluids, waste fluids, and batteries in an area with secondary containment (double drum,
drip pan) to capture leakage and contain spills.
4.3.2 Manage Vehicle Fluids
o Drain fluids from leaking or wrecked/damaged vehicles and equipment as soon as possible. Use
drip pans or plastic tarps to prevent spillage and spread of fluids.
r Promptly contain and transfer drained fluids to appropriate storage area for reuse, recycle, or
disposal.o Recycle automotive fluids, if possible, when their useful life is finished.
4.3.3 Use Controls During Paint Removal
o Use drop cloths and sheeting to prevent windborne contamination from paint chips and
sandblasting dust.o Collect, contain, and transfer, as soon as possible, accumulated dusts and paint chips to a disposal
location in the tailings area authorized to accept waste materials from maintenance or
construction activities.
4.3.4 Use Controls During Paint Application and Cleanup
o Mix and use the right amount of paint for the job. Use up one container before opening a second
one.
o Recycle or reuse leftover paint whenever possible.
o Never clean brushes or rinse or drain paint containers on the ground (paved or unpaved).o Clean brushes and containers only at sinks and stations that drain to the process sewer to the
tailings system.o Paint out brushes to the extent possible before water washing (water-based paint) or solvent
rinsing (oil-based paint).o Filter and reuse thinners and solvent whenever possible). Contain solids and unusable excess
liquids for transfer to the tailings area

4.4 Management Practices for Ore Pad, Tailings Area, and Heavy Equipment
Detailed instructions for ore unloading, dust suppression, and tailings management are provided
in the Mill SOPs.
4.4.1 Wash Down Vehicles and Equipment in Proper Areas
o Wash down trucks, trailers, and other heavy equipment only in areas designated for this purpose
(such as wash down pad areas and tile truck wash station).o At the truck wash station, make sure the water collection and recycling system is working before
turning on water sprays.
4.4.2 Manage Stockpiles to Prevent Windborne Contamination
o Water spray the ore pad and unpaved areas at appropriate frequency in accordance with Mill
SOPs.o Water spray stockpiles as required by opacity standards or weather conditions.o Don't over-water. Keep surfaces moist but minimize runoffwater.
4.4.3 Keep Earthmoving Activities from Becoming Pollutant Sources
o Schedule excavation, grading, and other earthmoving activities when extreme dryness and high
winds will not be a factor (to prevent the need for excessive dust suppression).o Remove existing vegetation only when absolutely necessary.r Seed or plant temporary vegetation for erosion control on slopes.

Re: State of Utah Ground Water Discharge Permit No. UGW370004 White Mesa Uranium Mill-
Notice Pursuant to Section 1.11(1) of the Spil! Prevention, Control, and Countermeasures Plan
and UAC 19-5-114: Response to Claricone Solution Spill
Dear Mr. Lundberg:
Please take notice pursuant to Section 1.1 1(1) of the White Mesa Mill's (the "Mill's") Spill Prevention, Control,
and Countermeasures ('SPCC') Plan and Utah Administrative Code ("UAC") 19-5-114 that Denison Mines
(USA) Corp. ("Denison"), as operator of the Mill and holder of the Permit, incurred a spill of process fluids
resulting from failure of the Claricone tank as described below.
The Claricone breakdown and spill was identified at approximately 12:50 pm on Thursday April 12,2012.
lnitial notice of this spill incident was given by voice mail and email to the Executive Secretary of the Utah
Department of Environmental Quality at 3:45 pm on Thursday April 12, 2012 a|801-536-4025 (within 24
hours of the discovery). During a subsequent phone call from DRC to Denison at approximately 4:30 pm on
April 12, 2012, Denison provided details of the incident to Mr. PhilGoble.
1. Notification of the Spill
a) The Claricone is a 29 112 foot diameter fiberglass conical separator cone which was located (both
physically and process-wise) between the uranium leach circuit and the solvent extraction circuit.
The Claricone contained approximately 28,000 gallons of solution containing water, sulfuric acid and
uranium salts. At the time of the incident described below, the Claricone was estimated to contain
approximately 420 gallons or 6,460 lbs. of sulfuric acid, and approximately 190 lbs. of uranium in an
aqueous solution at ambient temperature.
b) The Claricone was installed on a concrete pedestal which, along with the bottom third of the vessel,
was below ground and stabilized with soil backfill. The bottom valves and piping, consisting of high
density polyethyene ('HDPE') and polyvinyl chloride ('PVC") pipes, were accessible though a
horizontal conduit. The 4{oot diameter horizontal conduit referred to as the "Claricone Underflow
Tunnel", installed below grade, served as an access to the concrete pedestal and bottom piping. The

horizontal conduit joined a vertical conduit section which exited to the ground surface. The Claricone
Underflow Tunnel was accessed through a ladder in the vertical section. Access to the Claricone
Underflow Tunnel required procedures for confined space entry. Access to the top of the vessel was
via a steel walkway.
At 1:50 pm on April 12, 2012, the Claricone leaked its contents into the Claricone Underflow Tunnel
beneath the ground surface. Some portion of the contents in the horizontal portion of the Claricone
Underflow Tunnel leaked out through breaks into the surrounding soils. The Mill superintendent, near
the vessel at the time of the failure, observed solution rising to the ground surface, and a collapse of
surface soils into an apparent sink hole, above the horizontal section of the Claricone Underflow
Tunnel.
Section 1 .1 1(1) of the SPCC Plan requires that Denison:
i. Report spills to applicable government agencies as required by applicable laws and
regulations, and
ii. Perform cleanup in accordance with Section 1.8 of the SPCC Plan.
Corporate environmental management determined on April '11, 2012 that notification to DRC of the
failure and the resulting spill was required under Section 1.11(1)of the SPCC Plan and UAC 19-5-
114.
Denison provided email and voice mail notice to the Executive Secretary at 3:45 pm April 12,2012
and detailed information to Phil Goble of DRC at 4:30 pm on April 12, 2012, within 24 hours of
discovery. This verbal notification was followed by this written notification submitted within the time
frame committed to in phone conversations and email correspondence with DRC on April 19,2012,
and April 23,2012.
For conservatism, Denison estimated the volume of the entire contents of the Claricone spill, and the
sulfuric acid content of the entire Claricone volume, in order to assess whether a Reportable Quantity,
of sulfuric acid, as defined in the Mill's Storm Water Best Management Practices Plan, and SPCC
Plan, had been spilled. Denison's conservative estimate was that 420 gallons, or 6,460 lbs, of
sulfuric acid were spilled. Denison reported this quantity to DRC in the phone call of 4:30 pm April
12, 2012, along with the additional information that potentially approximately half of the spilled
material had not entered the environment and remained within the Claricone Underflow Tunnel. This
estimate has since been modified based on additional data collected during the response and
cleanup. lt is currently estimated that approximately 219 gallons of sulfuric acid were spilled to the
environment.
Denison also reported that maintenance was in the process of attempting to remove the solutions
from the Claricone Underflow Tunnel via portable pump, and the recoverable volume of solution was
as yet unknown. DRC instructed Denison to proceed with the spill response and removal action,
attempt to confirm the volume of process material pumped to Roberts Pond or removed by other
means, and to prepare a plan for the Executive Secretary addressing actions to date, and planned
cleanup actions.

3. Estimation of Spill Volume
The first observation of the Claricone from above the vesselfollowing the incident indicated that no more than
15 gallons remained in the bottom of the cone after the spill.
On Friday, April 13, 20'12, maintenance attempted to transfer the remaining free liquid solutions from the
Claricone Underflow Tunnel to Roberts Pond. The pumping attempt identified that only a small volume of
material remained as free liquid, with the majority bound in saturated mud in the tunnel and affected soil area.
The transfer pump operated at 70 gpm for approximately 30 minutes, transferring an estimated 2100 gallons
of solutions to Roberts Pond. The water-saturated mud could not be moved by the liquid pump.
The Claricone Underflow Tunnel was completely filled with mud when it was removed by crane and
transferred to Cell 3 for disposal. The volume of mud contained in the tunnel was approximately 11,28O
gallons.

Attachment 1 provides an estimate of the volume of solutions, and mass of sulfuric acid, from the spill that
may have reached the surrounding soil. Attachment 2 provides photographs depicting the conditions at the
time of and following the spill.
4. Procedure for Cleanup and Disposal
The Mill has performed cleanup and disposalof contaminated media from the spill as follows.
a) The Claricone, and the horizontal and vertical sections of the Claricone Underflow Tunnel, have been
taken out of service, excavated and lifted from their in-ground locations, cut up for transport, and
disposed in Cell3.
b) Contaminated solutions were pumped to the extent possible from the Claricone and the Claricone
Underflow Tunnel. Pumped solutions were transferred to Roberts Pond.
c) Contaminated soil was removed and disposed in Cell 3. The extent of soil removal addressed both
chemical and radiological contamination.
a. All soils visibly wet, stained or discolored were excavated until uncontaminated dry
background soils remained.
b. The bottom and sides of the excavation were scanned by microR meter (measuring residual
gamma contamination). When the bottom or sides of the excavation indicate gamma levels
greater than background levels, the excavation was resumed, additional contaminated soil
was removed, and the bottom and sides of the excavation were re-scanned until all surfaces
result in gamma levels less than or equalto cleanup background. (Cleanup background was
defined as two times the average of four measured background readings taken as described
in Attachment 3. This approach accounted for the contribution to background of gamma
radiation from other nearby process equipment such as the clarifier, thickener, and CCD
impounds.) When the bottom and sides of the excavation indicated gamma levels of less than
cleanup background as defined above, the excavation was considered complete, and the
area was prepared for backfilland re-grading.
A gamma survey was considered to be suitable because the spilled Claricone solutions contained appreciable
concentrations of gamma-emitting radionuclides.
Based on the above method, a total estimated volume of 1,134 cubic yards was removed and disposed in
Cell 3, along with the Claricone vessel, tunnel, and associated piping.
Attachment 3 provides a summary report of radiological measurements used to assess measured background
and confirm completion of the excavation.
5. Root Cause Analysis
On April 13, 2012, after it was determined the mud deposited in the Claricone Underflow Tunnel could not be
removed by pumping, Mill maintenance personnel removed the Claricone Underflow Tunnel in order to
access the bottom of the cone. lnspection of the bottom of the cone, and subsequent activities on April 16
and 17, 2012 lo remove the cone from its setting by lifting with a crane, identified that the Claricone had

experienced a fracture of the cone bottom which released the vessel contents into the Claricone Underflow
Tunnel. The velocity of the sudden release of fluids into the Claricone Underflow Tunnel resulted in fractures
of the Claricone and underflow piping, the tunnel at the horizontal/vertical conduit connection, and the
horizontal portion of the tunnel at several locations.
There appeared to be three points of material release to the environment, as follows.
1. A portion of the material was released from breakage at the buried base of the Claricone bottom,
approximately 9 feet below ground surface ("bgs").
2. The sudden discharge of Claricone contents into the Claricone Underflow Tunnel appears to have
ruptured the tunnel at several points, discharging material to the subsoil from 5 feet bgs to 9 feet bgs.
3. Some of the material which entered the Claricone Underflow Tunnel flooded the vertical shaft, exited
the top of the shaft, and entered into the drain pan to Roberts Pond. A portion of this material
overflowed the drain pan to the ground surface.
Material discharged through paths 1 and 2 seeped upwards towards the ground surface, saturating surface
soils, and resulting in the collapse noted by the Mill Superintendent.
6. Actions That Will be Taken to Prevent a Reoccurrence of this lncident
The following actions will be taken to prevent a reoccurrence of this incident:
The Claricone has been removed from service. The process piping between the leach circuit and solvent
extraction circuit will be modified to eliminate the need for this process step or piece of equipment in the short
term. Replacement options will be evaluated by Mill Management if this process step is required in the longer
term.
7. Compliance with SPCC Plan
ln satisfaction of Part 1D.10 of the Mill's Groundwater Discharge Permit, the spill was controlled in
accordance with the currently-approved SPCC Plan. The Mill's SPCC Plan, in Section 1.8, "Spill Discovery
and Remedial Action" requires the following steps be completed in response to a spill. Each step is listed in
italics followed by confirmation of how the step was implemented during the Claricone spill response.
"Chemicalor petroleum spills willbe handled as follows:
The Shift Foreman will direct efforts to shut down systems, is possible, to limit further releases."
o The Claricone fill valves and influent flows were shut off immediately after the failure was identified.
'The Shift Foreman willalso secure help if operators are requiring additionalassistance to contain the spill."
o The Shift Foreman and Mill Superintendent mobilized a multiple operator crew for response when the
failure was identified. Additional crew were mobilized for the ongoing cleanup effort beginning the day
after the incident.

'"The Shift Foreman is also obligated to initiate reporting procedures. Once control measures have begun and
personal danger is minimized, the Shift Foreman will notify the Production Superintendent, Maintenance
Superintendent, or Mill Manager."
o lnternal reporting to the Superintendents and Mill Manager occurred immediately. The Production
Superintendent was present near the equipment at the time of the incident and participated in the
notifications.
"The Production or Maintenance Superintendent will notify the Mill Manager, who in turn will notify the
Department Head of ENHS and/or the Environmental Coordinator."
. The Mill Manager designated the RSO to contact Corporate Environmental management. Notification
to the Corporate Director, Compliance and Permitting occurred within one hour of the incident.
"The Mill Manager w// assess the spill and related damage and direct remedial actions. The corrective
actions may include repairs, cleanup, disposal, and company notifications. Government notification may be
necessary in some cases."
o Corrective actions were implemented as described in Sections 2 and 4, above. Notification of the
Executive Secretary occurred as described in Section 1, above.
Please contact the undersigned if you have any questions or require any further information.

The soil removal in and around the old Claricone Area has been completed. Soils were removed that contained
visual contamination and also anything that had gamma radiological measurements that exceeded twice
background.
The background was determined from four locations to the west of the Claricone/Hobert's Pond area.
Background #1 was collected at approximately 100leet north ol ?{fiN27 and the reading was 18 pR/hr.
Background *2 was collec{ed approxirnately 1/10 of a mile west of MW27 and the reading was 16 gR/hr.
Background #3 was collected at approximately 100 feet west olifrrilZ7 and the reading was 18 pFUhr.
Background #4 was collected at approximately 25 leat north ol WW3 and lhe reading was 20 pR/hr. The
average background reading was determined to be 18 pF/hr.
A grid system uras created starting at the concrete walkway along Robert's Pond eastom embankment. The
grid was set at ten leet increments south and east from that point. The actual excavation area was
approximately 55 leet wide and 25 feet deap. Below are the readings gathered at the assigned locations:

APPENDIX B
TAILINGS INSPECTOR TRAINING
This document provides the training necessary for qualifying management-designated individuals for
conducting daily tailings inspections. Training information is presented by the Radiation Safety
Officer or designee from the Environmental Department. Daitytailings inspections are conducted in
accordance with the White Mesa Mill Tailings Management System and Discharge Minimization
Technology (DMT) Monitoring Plan. The Radiation Safety Officer or designee from the Radiation
Safety Department is responsible for performing monthly and quarterly tailings inspections. Tailings
inspection forms will be included in the monthly tailings inspection reports, which summarize the
conditions, activities, and areas of concern regarding the tailings areas.
Notifications:
The inspector is required to record whether all inspection items are normal (satisfactory, requiring no
action) or that conditions of potential concem exist (requiring action). A "check" mark indicates no
action required. ff conditions of potential concern exist the inspector should mark an "X" in the atea
the condition pertains to, note the condition, and specify the corrective action to be taken. If an
observable concern is made, it should be noted on the tailings report until the corrective action is
taken and the concem is remedied. The dates of all corrective actions should be noted on the reports
as well.
Any major catastrophic events or conditions pertaining to the tailings area should be reported
immediately to the Mill Manager or the Radiation Safety Officer, one of whomwill notify Corporate
Management. If dam failure occrrs, notify your supervisor and the Mill Manager immediately. The
Mill Manager will then notify Corporate Management, MSHA (303-231-5465), and the State of
Utah, Division of Dam Safety (801-538-7200).
Inspections:
All areas of the tailings disposal system are routinely patrolled and visible observations are to be
noted on a daily tailings inspection form. Refer to Appendix A for an example of the daily tailings
inspection form. The inspection form consists of three pages and is summarized as follows:
1. Tailings Slurry Transport System:
The slurry pipeline is to be inspected for leaks, damage, and sharp bends. The pipeline joints
are to be monitored for leaks, and loose connections. The pipeline supports are to be
White Mesa Mill - Standard Operating Procedures
Book 1 1: Environmental Protection Manual, Section 3.1
3/10 Revision: Denison-9
Page 38 of46
Flow Rates:
Presence of all flows in and out of the cells should be noted. Flow rates are to be estimated
in gallons per minute (GPM). Rates need to be determined for sluny lines, pond return, SX-
tails, and the spray system. During non-operational modes, the flow rate colurnn should be
marked as "0". The same holds true when the spray system is not utilized.
Physical Inspection of Slurry Line(s):
A physical inspection of all slurry lines has to be made every 4 hours during operation of the
mill. If possible, the inspection should include observation of the entire discharge line and
discharge spill point into the cell. If "fill to elevation" flags are in place, the tailings and
build-up is to be monitored and controlled so as to not cover the flags.
Dust Control:
Dusting and wind movement of tailings should be noted for Cells 2,3, ard 4A. Other
observations to be noted include a brief description of present weather conditions, and a
record of any precipitation received. Any dusting or wind movement of tailings should be
documented. tn addition, an estimate should be made for wind speed at the time of the
observed dusting or wind movement of tailings.
The Radiation Safety Department measures precipitation on a daily basis. Daily
measurements should be made as near to 8:00 a.m. as possible every day. Weekend
measurements will be taken by the Shifter as close to 8:00 a.m. as possible. All snow or ice
should be melted before a reading is taken.
Observations of Potential Concern:
All observations of concern during the inspection should be noted in this section. Corrective
action should follow each area of concern noted. All work orders issued, contacts, or
notifications made should be noted in this section as well. It is important to document all
these items in order to assure that the tailings management systemrecords are complete and
accurate.
Map of Tailings Cells:
The last section of the inspection involves drawing, as accurately as possible, the following
items where applicable.
1. Cover area
2. Beach/tailing sands area

Subject:Utah Division of Radiation Control June 21,2012 Storm Water Inspection at the
White Mesa Uranium Mill (Ground Water Module 65): DRC Close-out
Dear Ms. Tischler:
As you recall, the Utah Division of Radiation Control (DRC) issued a"Requestfor Information,
Notice of Enforcement Discretion and Confirmatory Actions" letter (Letter) to Energy Fuels
Resources (USA) Inc. (EFR), dated August 8,2012 regarding the DRC findings observed by DRC
staff during a June'2l ,2072 storm water inspection at the White Mesa Uranium Mill.
Per DRC review of the EFR responses and actions taken regarding the August 8,zl7zletter
required actions it appears that EFR has addressed the listed requirements. DRC does note that
follow up regarding several of the addressed items (e.g. onsite storm water inspector training and
improvements to the solvent extraction building roof drainage) will be assessed during future
inspections.
Based on the EFR responses the 2012 DRC storm water inspection is hereby closed-out.
If you have questions regarding this letter please contact Tom Rushing at [phone].

Notice of Enforcement I)iscretion and Conlirmatory Actions
Dear Ms. Tischler:
This is to transmit the findings of the Utatr Division of Radiation Control (DRC) 2012 storm water
inspection which took place on June 21,2012 at the White Mesa Uranium Mill (MilD. A copy of
the DRC modular inspection memo (Memo) is attached for your information. Based on the
findings during the inspection, DRC has the following Requests for Information, Notice of
Enforcement Discretion and Conlirmatory Actions as discussed during a close-out call between
DRC and Denison Mines USA Corp. (DUSA) on August 2,2012.
Additionally, DRC reviewed the DUSA INday 4,20l2letter regarding the actions taken in response
to the claricone solution spill which occurred at the Mill on April 12,2012. Specifically, DRC
reviewed the DUSA actions to insure that follow up was in conformance with the Spill
Prevention, Control and Countermeasures Plan.
Requestfor fnformafion
1. Standing water was observed in the area of the clean water tank, from an overflow or line
break at a shed (pump house?) south of the tank. Please provide an explanation of the
cause of the standing water and verification that the issue is resolved and that the standing

A work plan for the collection of confirmation soil samples to be collected and
atalyzedfor appropriate radiological parameters and total uranium within 45 days
from DUSA receipt of this letter. The work plan will detail the techniques to be
used for sample collection, number and locations of sarnples to be collected,
methods to be used for soils analysis, and will propose confirmation sample
concentration thresholds to be used for the evaluation. DUSA will propose
applicable concentration standards to be used for radiological parameters (per
applicable guidance/regulations); and will propose a study evaluation to determine
an appropriate background concentration for total uranium within the restricted
area of the Mill. The total uranium soil concentration threshold to be used for
confirmation samples will be based on 2 times the average measured background
concentrations for total uranium as determined through the work plan study, or;
A conservative basis for a larger three dimensional area of potentially
contaminated soil due to the claricone solution spill, in lieu of confirmation soil
sampling, which will include a calculated soil excavation volume (beyond the
p."riour excavated soil volume). DUSA will provide a Report which describes the
justifrcation for the calculated soil volume and includes a surface map of the Mill
and cross sections clearly depicting the ultimate area of soil for excavation,
removal and disposal (at site closure). DUSA will provide a surety estimate, for
Director review and approval, which includes line items for all work associated
with excavation, removal and disposal of the proposed soil volume. The Report
and Surety Estimate will be submitted within 45 days from DUSA receipt of this
letter.

2. The DUSA Spill Prevention, Control, and Countermeasures Plan, Part 1.6.1 requires the
documentation of a daily inspection of the propane tanks. Please include the inspection
findings with the daily inspection form used for storm water inspection documentation
within 30 days from your receipt of this letter.
Notice of Enforcement Discretion
1. The Utah Ground Water Permit, Permit No. UGW3 TOOO4,Part I.D.10 requires that"the
Permittee will manage all contact and non-contact stormwater and control contaminant
spills at thefocility in accordance with the currently approved Stormwater Best
Management Practices Plan." The approved Best Management Practices Plan, Appendix
l, Part l.lt Personnel Training and Spill Prevention Procedures requires that "all new
employees are instructed on spills at the time they are employed and trained. They are
briefed on chemical and petroleum spill prevention and control. They are informed that
lealcs in piping, valves, and sudden discharges from tanl<s should be reported immediately.
Abnormalflowsfrom ditches or impoundments are of immediate concern. In addition, a
safety meeting is presented annually by the Environmental Health and Safety Manager to
review the SPCC plan." Additionally, Part 1.11.I Training Records requires that
"Employee training records on chemical and petroleum spill prevention are maintained in
the general safety trainingfiles."
During the June 21,2012 White Mesa Mill stormwater inspection, the DRC inspectors
requested copies of the training records required by the SWPPP as well as a course outline
for the material presentations, in response they received;
A. Copies of certification forms from the Environmental Protection Manual, Section
3.1, Appendix C regarding certification that the undersigned received instruction of
the tailings system including documentation of daily tailings inspections, analysis
of potential problems and notification procedures and safety (3 forms total), and,B. A Copy of Appendix B of the Environmental Protection Manual, Section 3.1
"Tailings Inspector Training!'which includes an outline of the kaining program.
Per review of the provided documents DRC noted that the haining did not provide
instruction for items required by the Permit Part I.D.10 or any other topics related to spill
prevention, control or storm water pollution prevention. Additionally, it was noted that no
records for new employees were provided, only three forms were provided for the
following employees: David Turk, Tanner Holliday and Garrin Palmer. DUSA is in
violation of the Permit Part I.D.10 for failing to provide employee training as required by
the SWPPP.
DRC is extending enforcement discretion regarding this violation based on:
This was the first time that DRC has reviewed the haining syllabus, and,
DUSA will comply with the Confirmatory Action section, item2 below which
requires the development of a haining program in compliance with the Permit
within the specified timeline.

Conftrmatory Actions:
Per an August 2,2012 telephone close-out conference call, the following confirmatory actions and
timelines were agreed to:
1. Storm Water Best Management Practices Plan (SWBMPP) -- DRC notes that a complete
copy of the October, 2011 Revised SWBMPP (including all appendices) in both hard copy
and text searchable electronic format (PDF) has not been received. This was requested per
a DRC March 7 , 2012 Request for Information Letter, which also provided approval of the
October,20l I SWBMPP. A full copy was requested since the affachments were not
included; DRC noted that the Spill Prevention, Control and Countermeasure Plan
(Appendix I of the SWBMPP) was under review; and that the Emergency Response Plan
was not submitted due to there being no changes. DUSA will submit a complete revised
SWBMPP for DRC Files within 30 days of receipt of this letter.
2. Storm Water Inspector Training - DUSA will implement a training progmm in compliance
with the SWBMPP Appendix 1, Part 1.11 and will provide DRC a copy of the course
syllabus, training calendar, and commitment to maintain training logs/certificates at the
Mill within 60 calendar days of receipt of this letter.
DRC also notes that per a letter submitted to the Director by DUSA (dated October 17,
20ll) in response to a DRC RFI (dated September 1,2011), page Zltem 3. DUSA
provides information regarding the newly implemented internal notification process for
small quantity spills and commits that "all Mill employees will be trained to advise Mill
environmental personnel of any spills that they observe during the day, and these will also
be noted in the daily inspectionforz." Although the DUSA letter does not specify how the
information will be provided to the Mill employees, DUSA has agreed that this
information will be provided during the newly implemented SWBMPP training.
3. Solvent Extraction (SX) Building Roof Drainage Improvements - Comments regarding
needed improvements to the SX building roof drain system have been ongoing since 2009.
Per the 2012 inspection, issues related to the roof drainage and discharges into the
alternate feed circuit have not been addressed. DUSA agrees to upgrade the SX building
roof drainage to prevent potential standing water on the ground within 60 calendar days of
receipt of this leffer. Specifically, DUSA will provide appropriate drainage control for
roof areas depicted in photograph 30 of the Memo (north-west section of the building) and
will provide documentation to DRC regarding follow-up actions undertaken.
4. Based on DRC review of the DUSA May 4,2Ol2letter"Response to Claricone Solution
Spill'it was noted that confirmation soil sampling was not conducted to ensure that all
contaminated soil had been removed. Excavation of contaminated material was based on
visual examination and gamma surveying (microR meter) only. DUSA will submit to
DRC either:

Currently Approved Storm Water Best Management Practices Plan (SWBMPP) for the
White Mesa Uranium MiIl:
Date: October, 2011
RevisionNo. 1.4
Section I - Docament Review
SWBMPP (Documentatian Requirementil :
Part 4.1.4.- Diversion ditches, drainage channels and surface water control structures
in and around the MilI area wiII be inspected at least weekly. Areas requiring
maintenance or repair, such as excessive vegetative growth channel erosion or pooling
of surface water runoff, will be reported to appropriate departments and all follow up
actions are to be documented.
Findings:
The DRC conducted an inspection of upland Diversion Ditches and Berms as shown on the
DUSA Storm Water Best Management Practices Plan, Figure 1. DRC found the ditches and
benns to be adequately maintained. Photos of the ditches, taken during the day of the
inspection are inlhded the memo attachment, photo numbers 36,37,38 and 39.
DUSA inspects the diversion ditches and berms monthly and inspection "findings" fields are
included on the monthly inspection data form. DRC reviewed the April 30,2012 monthly
form and noted that the DUSA Inspector (GaITin Palmer) noted that the Diversion Ditches 1,
Z and.3 showed no sloughing, erosion, undesirable vegetation or obstructions of flow, and
tlrat"diversion ditches were checked dnd appear to be in good condition." It was noted that
the Diversion Berms showed no"stability issues or signs of distress."
Spiil Prentention, Control, and Count?rmeasures Plan (SPCCT (Docuruentation
Requirementsl:
1.6.1. - Daily monitoring of propane tanks required.
Findings: DRC notes that the propane tank inspection is not recorded on the daily inspection
forrn. This will be included as a request for information item.
1.9.1. - External Noffication of 66reportable quantity" spills.
Findings: A reportable quantity spill occurred of Claricone Solution (Frocess Fluids) on
Thursday April 12, 2012.
Follow up actions by Denison Mines were:
1. Spill identified at approximat e\y 12:5OP.M. on Thursday April 12,2oI2
2. E-mail notification of spill to DRC on April 12,2012 at 3:45 P.M.
3. Phone cal.l with DRC (Phil Goble) at 4:30 P.M. on April 12,20L2
4. Written notification and description of follow up actions dated May 4,2012 as
follows:a. The claricone leaked its contents into the underflow tunnel beneath ground
. surfac e (420 gallons of sutfuric acid and approximately 190 lbs of uranium in
an aqueous solution at ambient temperafure). Some portion ofthe contents in
the horizontal portion of the claricone underflow tunnel leaked out through
breaks into the surrounding soils. An observation of the collapse of surface
soils near the claricone and rising solution were noted by the Mill
superintende'lrt.b. Containment actions take,n by DUSA per the May 4,2012 DUSA letter:

transferred to cell3 for disposal. The volume of mud in the tunnel was
re,ported to be approximately 11,280 gallons.
The bottom and sides of the excavation were scanned by microR meter to
measure residual gamma contamination. The cleanup confirmation samples
were taken until readings were less than or equal to "cleanup backgrotrnd"
which was defined as two times the average of four measured backgrotrnd
reading taken by DUSA. Per attachment 3 of the letter the four background
readings \{rere taken "to the west of the Claricone/Roberts Pond area.
Background #1 was collected at approxirnately 100feet north of MW27 and
the readingwas 18 ltR/hr,
Background #2 was collected approximately 1/10 of a milewest of MW-27
and the reading was I 6 ltR./hr,
Background #3 was collected approximately 100feet west of MW-25 and the
readingwas I8 ltR/hr,
Background ll4 was collected approximately 25 feet north of WWj and the
readingwas 20 ttNhr
71te average background readingwas determined to be I8 pR./hr"
Therefore, DUSA used a clean-up background corcentation of 36 pR/hr, and
justifies the clean up above background since "this approach accountedfor
the contribution to background of gamma radiationfrom other nearby process
equipment such as the clarifier, thickener, and CCD impounds. DRC notes
that no soil samples were taken to veriff concentrations, DUSA used the
meter only.
3
DUSA notes that the horizontal portion of the claricone tunnel was full of
mud and was not able to be pumped and was therefore removed by crane. and
To ensure that the excavated soils area was broad enough to remove all
contamination, DUSA will be required through confirmatory action letter
(CAL) to prepare either:
i) A workplan for the collection of confirrnation soil samples to be
collected and analyzed for appropriate radiological pararneters and
total uranium within 45 days from DUSA receipt of the cAL. The
work plan will detail the techniques to be used for sample collection,
number and locations of samples to be collected, methods to be used
for soils analysis, and will propose confirmation sample concentration
thresholds,to be used for the evaluation. DUSA will propose
applicable concentration standards to be used for radiological
parameters (per applicable guidance/regulations); and will propose a
study evaluation to detennine an appropriate background
concentration for total uranium within the reshicted area of the Mill.
The total uranium soil concentration threshold to be used for
confirmation samples will be based on 2 times the average measured
background concentrations for total uranium as determined through the
work plan sfudy, or;
ii) A consewative basis for a larger three dimensional area of potentially
contarninated soil due to the claricone solution spill, in lieu of
confirmation soil sampling, which will include a calculated soil
excavation volume (beyond the previous excavated soil volume).
DUSA will provide a Report whilh describes the justification for the
calculated soil volume and includes a surface map of the Mitl and
cross sections clearly depicting the ultimat" ,rea of soil for excavation,
removal and disposal (at site closure). DUSA will provide a surety
estimate, for Director review and approval, which includes line items
for all work associated with excavation, removal and disposal of the
proposed soil volume. The Report and Surety Estimate will be
required to be submitted within 45 days from DUSA receipt of the
CAI.
l:g.2. Internal Notification of incidents, spills, and siguificant spills.
Performance Standards (list):
In response to a DRC Request for Information item by letter dated September l,2}ll,
r"g*diog the findings of the DRC 2010 storm water inspection, DUSA provided a change to
the small quantity spills protocols in the October 17,2011 response letter, as follows:
*DUSA has implanted an internal notification processfor small quantity spills (ess than
reportable quantities), with the following steps :
1) Milt environmental personnet willfitl out on the daily inspectionform observations of
spills of reagent chemicals of .any size. Theform will be amended to add spaces for this item.
4
o
2) In addition, all Mill employees will be trained to advise Mill environmental personnel of
iny spilts that thqt observe during the day, and these will also be noted in the daily
';i;:f::i?;# of a reportabte quantity, environmentat personne'tt witt fottow the proced.ures
in the Mill's SWMPP Plan.
4) For spills smaller thin reportable quantities, the environmental inspector will record
io\or*itton regarding the spill, and the nature and type of cleanup, on theform'
sj rne informition oi the iispectionform will be added to a database maintained at the Mill,
,ine datibase will be updatei and maintaine(. on site indefinitely. lards are maintainedfor
no longer than one year."
These corrective actions were reviewed during the DRC June 21, 2012 storm water
inspection. per review DRC noted that a process for intemal reporting of spills less than
reportable quantities has been instituted-
The White Mesa Mill employees are using an orange card to report the spills, the card is title
,,Non-Reportable neportibli Spillage-. DRC requested copies of all reports (filled in cards)
since the implementation of thi reporting process and received 9 reports as listed on the table

DRC sees the new spill reporting process as effective. DRC notes that the spill reporting
training program required under the requirements of the Spill Prevention, Control, and
Countenneasures Plan for Chernicals and Petroleum Product, Section 1.11., and also outlined
in the DUSA response as a corrective action, has not been implemented. This is in violation
of the Permit us dir"rrss"d in Section 1.11 below, DRC will use enforcement discretionbased
on DUSA agreement to prepare a training module and program as specified in a confirmatory
action letter.

No. of On-site Records Found: All Records/Reports Onsite
No ofRecords Examined: l0o/o @ercent of Total)
How Selected: DRC Inspected a full month of daily, weekly and monthly forms
Daily failings fnspection Data:
Findings:
DUSA inspection of: 1. Tailings slurry transport system; 2. Operational systems (water level,
beach, liner and cover); 3. Dikes and embankrnents; 4. Physical inspection of the slurry lines,
and; 5. Dust control and leak detection, are conducted daily and documented on a daily
inspection form. DRC randomly selected and reiriewed all of the daily foims for the month
of ipril, 2012. DRC noted ttraithe Claricone Solution Spill which occurred on April 12,
2Ol1wasnot recorded on the daily inspection form & only briefly noted on the weeHy forrn
(without inclusion of spill volume or clean up actions)
Per discussion of internal identification of small quantrty spills, DRC notes that DUSA has
implemented a separated process for staff to report those occrurences as discussed above.
Weekly Tailings Inspections and Survey:
Findings: A weekly tailings inspection was done and documented on a weekly tailings
inspection form. The form includes sections to document pond elevations (solution
elevation, FML bottom elevation, and depth of water above FML) for Cells 1,3,4A,4B and
Roberts Pond, as well as slimes drain liquid levels in Cell 2. The forrr also includes
information regarding the leak detection systems for Cells 1,2,3,4A and 48 as well as the
potential blowing of tailings. The form, as part of the Standard Operating Procedures, also
6
includes sections for reporting parameters about the Leak Detection Systems (part of the
DMT plan requirements, not storm water related).
Per the 2012 DRC storm water inspection, there are no comments regarding the forms.
Monthly lailin gs Inspection, Pipeline Thickness :
Findings:
The monthly inspection report includes; 1. A summary of the slurry pipeline condition and
measnrement of pipe tlickness, which is applicable only when the Mill is operational;2.
Inspection protocols and observations related to the diversion ditches, benns, sedimentation
pond, dust control, settlement monitors, and slimes drain static head measurements for Cells
2 and3.
DRC reviewed the monthly inspection report dated April 3L,z()lz.Note that the monthly
inspection reports include comments related to the upland diversion ditches. DRC has no
additional comments related to the reviewed monthly inspection report.
Tank to soil potential measurements:
Findings:
This item was included as part of the September L,2011 RFI, RFI # 2. DRC had concerns
regarding on-grade tanks (tanks where the bottom is in contact with soil. Per DRC
communication with DUSA it was clarified that tanks which sit on the ground must have
cathodic protection installed if they are in oontact with soil or must be placed on a concrste
foundation (no steeUsoil contact).
The DUSA October 17,z0Ll.response states:
" .. .The following results of the tank inspection were noted:
o There are three kerosene tanks. The east tank is on a concrete pedestal. The two
west tanks are place on-grade, on the ground surface.o The ammonia tanks are on concrete pedestals.o The sulfuric acid tank is on a concrete pedestalo The acterior VPL and water tank by the Old Decontamination Pad are on concrete
pedestals. Dirt hadfilled in the area around the pedestals and, at the time of the
2010 inspection, gave the mistaken irnpression that the tanks wer on grade.
DUSA had discussed with the DRC the installatfon of cathodic protection on reagent orfuel
tanla that were not on pedestals, saddles or dikes, specifically the kerosene tanks. DUSA has
since decided that it would be more prudent to construct comparable concrete bases
(pedestals) for the remaining kerosene tanks, as are in place on the otherflat bottom
tanks..-"
The DRC communication that concrete pedestals were appropriate (in lieu of cathodic
protection) was sent to DUSA via e-mail on September 26,2011. Therefore, the DUSA
action is appropriate and is consistent with State and Federal regulations.
Per DRC inspection of the tank foundations during the20l2 storm water inspectioq it was
verified that all pertinent tank concrete foundations, including the kerosene tanks, have been
completed and appeared in good condition.
Annual bulk oil and fuel tank visual inspections:
rmomgs:
In response to a DRC request for information, DUSA is currently reviewing the current Spill
Prevention Countenneasure and Control Plan for the mill to ensure that all inspection
processes and oil containers are in conformance with those Federal (40CFR112) regulations.
Tank and pipeline thickness tests:
Findings: Per DRC review, the only thickness test noted was the slurry pipeline thickness
and this is onlytaken during times when the Mill is operating.
Quarterly and annual PCB transformer inspections (currently PCB only):
Findings:
The Mill currently does not currently inspect the transformers based on all transformers
containing non-PCB based oil. Follow up regarding this issue will be tracked with the
DUSA review of the SPCC Plan and Protoiols as discussed above.
Spill Incident Reports :
Findings:
This item is discussed above in the section related to reportable and small quantity spills.
Latest revision of SPCC plan (onsite and available?):
Findings: The current SPCC plan was onsite and available during the inspection.
1.11 Personnel training and Spill Prevention Procedures (records of training required
to be maintained in the general safety training files):
The Utah Ground Water Permit, Permit No. UGW3 7OO})4,Part I.D.10 requires that"the Permittee
will manage all contact and non-contact stormwater and control contaminant spills at thefacility in
accordancewith the carrently approved Stormwater Best Managernent Practices Plan." Tl;re
approved Best Management Practices Plan, Appendix 1, Part l.ll Personnel Training and Spill
Prevention Procedures requires that"all new employees are instructed on spills at the time thqt are
employed and trained. They are briefed on chemical and petroleum spill phevention and control.
They are informed that leaks in piping, valves, and sudden dischargesfrom tanks should be reported
8
immediately. Abnormalflowsfrom ditches or impoundments are ofimmediate concern. In addition,
a safety meeting is presented annually by the Environmental Health and Safety Manager to review the
SPCC plan." Additionally, Part 1.11.1 Training Records requkesthat"Employee training records on
chemical and petrolanm spill preverztion are maintained in the general safety trainingfiles."
During the June 2l,2}lzWhite Mesa Milt stormwater inspection, the DRC inspectors requested
copies of the training records required by the SWPPP as well as a course outline for the material
presentation and were grven,
A. Copies of certification forms from the Environmental Protection Manual, Section
3.1, Appendix C regarding certification that the undersigned received instruction of
the tailings system including documentation of daily tailings inspections, analysis of
potential problerns and notification procedures and safety, and,B. A Copy of Appendix B of the Environmental Protection Manual, Section 3.1
"Tailings Inspector Training!'which includes an outline of the trainingprogram.
Per review of the provided documents DRC noted that the training did not provide instruction for
items required by the Permit Part I.D.10. Additionally, it was noted that no records for new
employees were provided, only three forms were provided for the following employees: David Turlq
Tanner Holliday and Garrin Palmer. These are the ernployees most directly involved with inspection
of the tailings management system. Additionally, it was noted that the taining form for Tanner
Holliday was authorized by David Turh and that the form for David Turk was authorized by Tanner
Holliday. DUSA is in violation of the Permit Part I.D.10 for failing to provide employee taining as
required by the SWPPP. This issue will be tansmitted to DUSA as a Notice of Enforceme,nt
Discretion based on DUSA confirmatory action to prepare and institute a storm water/spills training
program.
Seclion II - Site Walk through fnspec.tion
Areas and Observations:
Ore Storage:
Observations: The berm and collection drain on the southern boundary of the tailings storage
area was maintained, although DRC did note one area where soil was located such that storm
water would be diverted directly into the berm and may cause a breach of the berm and
offsite discharge. @hotos 5,6 andT)
DRC also noted that the offsite drainage noted on the northern part of the ore storage pad,
north of the new decontamination facility (drainage ditch and sump) has been
improved/repaired per DUSA corrective actions included in response to a DRC RFI @hotos
8 and 9).
Reagent Yard:
Observations:
Per DRC inspection of the reagent yard and storage building, it appeared that drum storage
was appropriate. No degraded or tapped drums were noted in those areas.
Shop/Y'ehicle Maintenan ce Area :
Observations:
Oil Drum Storage Rack:
Per DRC inspection it was noted that the storage rack has been removed and replaced with
pallets (with secondarycontainm66). This actionwas undertaken in response to aDRC
Notice of Violation. The corrective actions appear appropriate. @hotos 18 and 19)
Shop Building Dmin to Baffle Box:
Per DRC inspection of the shop baffle box, no comments were noted
Used Oil/Kerosene TankNorrh of Shop Building:
Per DRC inspection of the used oil tank and kerosene tank containment, it appeared that
previous violations concerning spills outside of the containments were addressed, no
additional issues/comments were noted. @hoto 17)
MilI Processing Areas:
SX Building Roof Drainage:
Comments regarding needed improvements to the SX building roof drain system are ongoing
since 2009. Per tbe2012 inspection, issues related to the roof drainage and discharges into
the alternate feed circuit have not been addressed. This item willbe included as a
confirmatory action item. @hotos 30, 31)
Alternate Feed Circuit South of SX Building:
Observations:
DRC noted that a new section of concrete pad was constructed to address issues of temporary
storage of alternate feed drums @hoto 29). Additionally other areas of altemate feed drum
storage outside of the feedstock management area were placed on the newly constructed
concrete pad (Photo 28). DRC has no additional comment/observations regarding the
alternate feed area.
OId Decontamination Pad:
DRC noted that the discharge vault was being drained at the time of the inspection
@hoto 21). DRC has no additional comments regarding the old decontaminationpad.
New Decontamination Pad:
10
Observations:
Irr response to a DRC Notice of Violation conceming the leaking pump-back system
(recirculation system), noted during 2011, DUSA expanded the concrete pad area undemeath
the pump, no additional comments were noted.
Reagent Tanks:
Sodium Chloride Tanks - Per past agreements between DRC and DUSA (Agreements
made in 2005) the secondary containment for these tanks is earthen. Per the agreement, all
reagent tanks that pre-existed the Ground Water Permit (3105) would be acceptable as is -
and that as upgrades or replacements were installed, DUSA would work to meet BAT
requirements. More detail regarding this agreement is in the December 2004 Statement of
Basis, and in Part I.D.3(g). @hoto 1)
Kerosene Tanks (West of Shop) - DUSA has provided concrete foundations for the tanks as
per the 2011 DRC RFI #2 (See Above) and the DUSA l0/L712011 Response. @hotos 2)
Secondary containment is earthen under the same agreement as the sodium chloride tanks.
Ammonia Tanks - DRC noted that the tank was undergoing maintenance/refurbishing at the
time of the inspection (sandblasting and re-painting). Secondary containment is earthen per
the same agreement as the sodium chloride tanks. @hoto 4)
Used Oil Tank (shop) - See Shop/Vehicle Maintenance Areas comments above.
Kerosene Tank (shop) - See Shop/Vehicle Maintenance Areas comments above.
FueI Tanks -Above ground tanks and containment appeared maintained, no additional
comments.
Uranium Liquor Tanks - DRC had no comments regarding tanks or secondary
containment.
Yanadium Pregnant Liquor CVPL) Tanks - The \IPL tank steam condensate containment
area, tanks and foundations appeared to be in good condition. @hoto 20)
Clean Water Tank - The construction of an underground pipeline has eliminated the
vegetated ditch and standing water concerns per the 2011 DRC inspection @hoto 24). DRC
did note that water was pooling on the west side of a pumphouse (south of the water tank).
DRC will include repair of the leak as a request for information (Photo 25).
Sulfuric Acid Tank - The tank appeared in good condition @hoto 26).
Propane Tank - Tanks were not inspected during this inspection, note that leaks would be
likely be in gas form.
11
Caustic Soda Tank - Per the20l2 inspection it was noted that, in response to Confirmatory
Actions, the caustic acid secondary containment area has been re-poured and that anew tank
is in the process ofbeing installed @hotos 32 and33).
Soda Ash Tanks - The Soda Ash Tanks and Secondary Containment appeared to be in good
condition/repair. DRC has no comments regarding this area. (Photo 34)
Taitings Cells Areas (Note that upland drainage was included in comments above) -
DRC toured the tailings cell areas (Cells 4A and 4B and observed the condition of the outer
toe areas of the dikes to ensure that excessive erosion or damage (e.g. burrowing animal
intrusion or rooting damage) was not present. Although DRC did note some minor burrowing
activities, the dikes appeared to be in overall good condition and sections where rilling was
evident had been re-graded. @hoto 35)

Currently Approved Storm Water Best Management Practices Plan (SWBMPP) for the
White Mesa Uranium Mill:
Date: October,20ll
Revision No. 1.4
Section I - Document Review
SWBMPP (Documentation Requirements) :
Pzrt 4.1.4. - Diversion ditches, drainage channels and surface water control structures
in and around the Mill area will be inspected at least weekly. Areas requiring
maintenance or repair, such as excessive vegetative growth channel erosion or pooling
of surface water runoff, will be reported to appropriate departments and all follow up
actions are to be documented.
Findings:
The DRC conducted an inspection of upland Diversion Ditches and Berms as shown on the
DUSA Storm Water Best Management Practices Plan, Figure 1. DRC found the ditches and
berms to be adequately maintained. Photos of the ditches, taken during the day of the
inspection are included the memo attachment, photo numbers 36,37,38 and 39.
DUSA inspects the diversion ditches and berms monthly and inspection "findings" fields are
included on the monthly inspection data form. DRC reviewed the April 30, 2012monthly
form and noted that the DUSA Inspector (Ga:rin Palmer) noted that the Diversion Ditches 1,
2 and 3 showed no sloughing, erosion, undesirable vegetation or obstructions of flow, and
that"diversion ditches were checked and appear to be in good condition." It was noted that
the Diversion Berms showed rro"stability issues or signs of distress."
Soill Prevention. Control, and Countermeasures Plan (SPCC) (Documentation
Requirementsl:
1.6.1. - Daily monitoring of propane tanks required.
Findings: DRC notes that the propane tank inspection is not recorded on the daily inspection
form. This will be included as a request for information item.
1.9.1. * External Notification of "reportable quantity" spills.
Findings: A reportable quantity spill occurred of Claricone Solution (Process Fluids) on
Thursday Apil 12,20t2.
Follow up actions by Denison Mines were:
1. Spill identified at approximately 12:50 P.M. on Thursday Apil12,20122. E-mail notification of spill to DRC on April 12,2012 at 3:45 P.M.
3. Phone call with DRC (Phil Goble) at4:30 P.M. on April12,2012
4. Written notification and description of follow up actions dated May 4,2012 as
follows:
a. The claricone leaked its contents into the underflow tunnel beneath ground
surface (420 gallons of sulfuric acid and approximately 190 lbs of uranium in
an aqueous solution at ambient temperature). Some portion of the contents in
the horizontal portion of the claricone underflow tunnel leaked out through
breaks into the surrounding soils. An observation of the collapse of surface
soils near the claricone and rising solution were noted by the Mill
superintendent.
b. Containment actions taken by DUSA per the May 4,2012 DUSA letter:

DUSA notes that the horizontal portion of the claricone tururel was full of
mud and was not able to be pumped and was therefore removed by crane and
transferred to cell 3 for disposal. The volume of mud in the tunnel was
reported to be approximately 11,280 gallons.
The bottom and sides of the excavation were scanned by microR meter to
measure residual gamma contamination. The cleanup confirmation samples
were taken until readings were less than or equal to "cleanup background"
which was defined as two times the average of four measured background
reading taken by DUSA. Per attachment 3 of the letter the four background
readings were taken "to tlte west of the Claricone/Roberts Pond area.
Background #l was collected at approximately 100feet north of MW27 and
the readingwas l8 1tR/hr,
Background #2 was collected approximately l/10 of a mile west of MW-27
and the reading was l6 NUhr,
Background #3 was collected approximately l00feet west of MW-25 and the
reading was 18 t-R/hr,
Background ll4 was collected approximately 25 feet north of WW3 and the
reading was 20 NUh,
The average background reading was determined to be l8 1tR/hr"
Therefore, DUSA used a clean-up background concentration of 36 pRftr, and
justifies the clean up above background since"this approach accountedfor
the contribution to background of gamma radiationfrom other nearby process
equipment such as the clarifier, thickener, and CCD impounds. DRC notes
that no soil samples were taken to verify concentrations, DUSA used the
meter only.
e. To ensure that the excavated soils area was broad enough to remove all
contamination, DUSA will be required through confirmatory action letter
(CAL) to prepare either:
D A work plan for the collection of confirmation soil samples to be
collected and analyzed for appropriate radiological parameters and
total uranium within 45 days from DUSA receipt of the CAL. The
work plan will detail the techniques to be used for sample collection,
number and locations of samples to be collected, methods to be used
for soils analysis, and will propose confirmation sample concentration
thresholds to be used for the evaluation. DUSA will propose
applicable concentration standards to be used for radiological
parameters (per applicable guidance/regulations); and will propose a
study evaluation to determine an appropriate background
concentration for total uranium within the restricted area of the Mill.
The total uranium soil concentration threshold to be used for
confirmation samples will be based on 2 times the average measured
background concentrations for total uranium as determined through the
work plan study, or;
iD A conservative basis for a larger three dimensional area of potentially
contaminated soil due to the claricone solution spill, in lieu of
confirmation soil sampling, which will include a calculated soil
excavation volume (beyond the previous excavated soil volume).
DUSA will provide a Report whi6h describes the justification for the
calculated soil volume and includes a surface map of the Mill and
cross sections clearly depicting the ultimate areaof soil for excavation,
removal and disposal (at site closure). DUSA will provide a surety
estimate, for Director review and approval, which includes line items
for all work associated with excavation, removal and disposal of the
proposed soil volume. The Report and Surety Estimate will be
required to be submitted within 45 days from DUSA receipt of the
CAL.
1.9.2. Internal Notification of incidents, spills, and significant spills.
Performance Standards (list):
In response to a DRC Request for Information item by letter dated September l,20ll,
regarding the findings of the DRC 2010 storm water inspection, DUSA provided a change to
the small quantity spills protocols in the October 17,2011 response letter, as follows:
*DUSA has implanted an internal notification process for small quantity spills (ess than
reportable quantities), with the following steps :
I) Mill environmental personnel willfill out on the daily inspectionform observations of
spills of reagent chemicals of any size. The form will be amended to add spaces for this item.
2) In addition, all Mill employees will be trained to advise Mill environmental personnel of
any spills that they observe during the day, and these will also be noted in the daily
inspectionform.
3) If the spill is of a reportable quantity, environmental personnel will follow the procedures
in the Mill's SWMPP plan.
4) For spills smaller than reportable quantities, the enyironmental inspector will record
information regarding the spill, ond the nature and type of cleanup, on theform.
5) The information on the inspectionform will be added to a database maintained at the Mill.
The database will be updated and maintained on site indefinitely. Cards are maintainedfor
no longer than one year."
These corrective actions were reviewed during the DRC June 21, 2012 storm water
inspection. Per review DRC noted that aprocess for internal reporting of spills less than
reportable quantities has been instituted.
The White Mesa Mill employees are using an orange card to report the spills, the card is title
"Non-Reportable Reportable Spillage". DRC requested copies of all reports (filled in cards)
since the implementation of the reporting process and received 9 reports as listed on the table
below:

DRC sees the new spill reporting process as effective. DRC notes that the spill reporting
training program required under the requirements of the Spill Prevention, Control, and
Countermeasures Plan for Chemicals and Petroleum Product, Section 1.11., and also outlined
in the DUSA response as a corrective action, has not been implemented. This is in violation
of the Permit as discussed in Section 1.1 I below, DRC will use enforcement discretion based
on DUSA agreement to prepare a training module and program as specified in a confirmatory
action letter.
1.10 Records and Reports.
Period of Records Examined During Inspection:
Begin/Ending: 4/ 112012 through 413012012
No. of On-site Records Required: Daily, Weekly and Monthly Forms
No. of On-site Records Found: All Records/Reports Onsite
No of Records Examined: l0%o (Percent of Total)
How Selected: DRC Inspected a full month of daily, weekly and monthly forms
Daily Tailings Inspection Data:
Findings:
DUSA inspection of: l. Tailings slurry transport system; 2.Operational systems (water level,
beach, liner and cover); 3. Dikes and embankments; 4. Physical inspection of the slurry lines,
and; 5. Dust control and leak detection, are conducted daily and documented on a daily
inspection form. DRC randomly selected and reviewed all of the daily forms for the month
of April, 2012. DRC noted that the Claricone Solution Spill which occurred on April 12,
2012 was not recorded on the daily inspection form & only briefly noted on the weekly form
(without inclusion of spill volume or clean up actions).
Per discussion of intemal identification of small quantity spills, DRC notes that DUSA has
implemented a separated process for staff to report those occurrences as discussed above.
Weekly Tailings Inspections and Survey:
Findings: A weekly tailings inspection was done and documented on a weekly tailings
inspection form. The form includes sections to document pond elevations (solution
elevation, FML bottom elevation, and depth of water above FML) for Cells 1,3,4A,4B and
Roberts Pond, as well as slimes drain liquid levels in Cell 2. The form also includes
information regarding the leak detection systems for Cells 1,2,3,4A and 4B as well as the
potential blowing of tailings. The form, as part of the Standard Operating Procedures, also
6
includes sections for reporting parameters about the Leak Detection Systems (part of the
DMT plan requirements, not storm water related).
Per the 2012 DRC storm water inspection, there are no comments regarding the forms.
Monthly Tailings Inspection, Pipeline Thickness:
Findings:
The monthly inspection report includes; 1. A summary of the slurry pipeline condition and
measurement of pipe thickness, which is applicable only when the Mill is operational; 2.
Inspection protocols and observations related to the diversion ditches, berms, sedimentation
pond, dust control, settlement monitors, and slimes drain static head measurements for Cells
2 and3.
DRC reviewed the monthly inspection report dated April 30, 20l2.Note that the monthly
inspection reports include comments related to the upland diversion ditches. DRC has no
additional comments related to the reviewed monthly inspection report.
Tank to soil potential measurements:
Findings:
This item was included as part of the September 1,2011 RFI, RFI # 2. DRC had concerns
regarding on-grade tanks (tanks where the bottom is in contact with soil. Per DRC
communication with DUSA it was clarified that tanks which sit on the ground must have
cathodic protection installed if they are in contact with soil or must be placed on a concrete
foundation (no steeUsoil contact).
The DUSA October 17,2011 response states:
" . . .The following results of the tank inspection were noted:
c Tltere are three kerosene tanlrs. The east tank is on a concrete pedestal. The two
west tanl<s are place on-grade, on the ground surface.
. The ammonia tanl<s are on concrete pedestals.
o The sulfuric acid tank is on a concrete pedestalo The exterior YPL and water tank by the Old Decontamination Pad are on concrete
pedestals. Dirt hadfilled in the area around the pedestals and, at the time of the
2010 inspection, gave the mistaken impression that the tanl<s wer on grade.
DUSA had discussedwith the DRC the installation of cathodic protection on reagent orfuel
tanlrs that were not on pedestals, saddles or dikes, specifically the kerosene tanks. DUSA has
since decided that it would be more prudent to construct comparable concrete bases
(pedestals) for the remaining kerosene tanks, as are in place on the other/lat bottom
tanl<s..."
The DRC communication that concrete pedestals were appropriate (in lieu of cathodic
protection) was sent to DUSA via e-mail on September 26,2011. Therefore, the DUSA
action is appropriate and is consistent with State and Federal regulations.
Per DRC inspection of the tank foundations during the2012 storm water inspection, it was
verified that all pertinent tank concrete foundations, including the kerosene tanks, have been
completed and appeared in good condition.
Annual bulk oil and fuel tank visual inspections:
Findings:
In response to a DRC request for information, DUSA is currently reviewing the current Spill
Prevention Countermeasure and Control Plan for the mill to ensure that all inspection
processes and oil containers are in conformance with those Federal (40CFR112) regulations.
Tank and pipeline thickness tests:
Findings: Per DRC review, the only thickness test noted was the slurry pipeline thickness
and this is only taken during times when the Mill is operating.
Quarterly and annual PCB transformer inspections (currentty PCB only):
Findings:
The Mill currently does not currently inspect the transformers based on all transformers
containing non-PCB based oil. Follow up regarding this issue will be tracked with the
DUSA review of the SPCC Plan and Protocols as discussed above.
Spill Incident Reports:
Findings:
This item is discussed above in the section related to reportable and small quantity spills.
Latest revision of SPCC plan (onsite and available?):
Findings: The current SPCC plan was onsite and available during the inspection.
1.11 Personnel training and Spill Prevention Procedures (records of training required
to be maintained in the general safety training files):
The Utah Ground Water Permit, Permit No. UGW370004, Part I.D.10 requires ttwt"the Permittee
will manage all contact and non-contact stormwater and control contaminant spills at thefacility in
accordance with the currently approved Stormwater Best Management Practices Plan." Tlte
approved Best Management Pracfices Plan, Appendix 1, Part l.ll Personnel Training and Spill
Prevention Procedures requires that"all new employees are instructed on spills at the time they are
employed and trained. Thqt are briefed on chemical and petroleum spill prevention and control.
They are informed that leaks in piping, valves, and sudden dischargesfrom tanks should be reported
8
immediately. Abnormalflowsfrom ditches or impoundments are of immediate concern. In addition,
a safety meeting is presented annually by the Environmental Health and Safety Manager to review the
SPCC plan." Additionally, Part l.ll.l Training Records requires that*Employee training records on
chemical and petroleum spill prevention are maintained in the general safety trainingfiles."
During the June 2L,2012 White Mesa Mill stormwater inspection, the DRC inspectors requested
copies of the training records required by the SWPPP as well as a course outline for the material
presentation and were given,
A. Copies of certification forms from the Environmental Protection Manual, Section
3.1 , Appendix C regarding certification that the undersigned received instruction of
the tailings system including documentation of daily tailings inspections, analysis of
potential problems and notification procedures and safety, and,B. A Copy of Appendix B of the Environmental Protection Manual, Section 3.1
"Tailings Inspector Training" which includes an outline of the training program.
Per review of the provided documents DRC noted that the training did not provide instruction for
items required by the Permit Part I.D.10. Additionally, it was noted that no records for new
employees were provided, only three forms were provided for the following employees: David Turk,
Tanner Holliday and Garrin Palmer. These are the employees most directly involved with inspection
of the tailings management system. Additionally, it was noted that the faining form for Tanner
Holliday was authorizedby David Turk, and that the form for David Turk was authorized by Tanner
Holliday. DUSA is in violation of the Permit Part I.D.10 for failing to provide employee training as
required by the SWPPP. This issue will be transmitted to DUSA as a Notice of Enforcement
Discretion based on DUSA confirmatory action to prepare and institute a storm water/spills training
program.
Section II - Site Walk through Inspection
Areas and Observations:
Ore Storage:
Observations: The berm and collection drain on the southern boundary of the tailings storage
area was maintained, although DRC did note one area where soil was located such that storm
water would be diverted directly into the berm and may cause a breach of the berm and
offsite discharge. (Photos 5,6 andT)
DRC also noted that the offsite drainage noted on the northem part of the ore storage pad,
north of the new decontamination facility (drainage ditch and sump) has been
improved/repaired per DUSA corrective actions included in response to a DRC RFI (Photos
8 and 9).
Reagent Yard:
Observations:
Per DRC inspection of the reagent yard and storage building, it appeared that drum storage
was appropriate. No degraded or tapped drums were noted in those areas.
9
Shop/Yehicle Maintenance Area:
Observations:
Oil Drum Storage Rack:
Per DRC inspection it was noted that the storage rack has been removed and replaced with
pallets (with secondary containment). This action was undertaken in response to a DRC
Notice of Violation. The corrective actions appear appropriate. (Photos 18 and 19)
Shop Building Drain to Baffle Box:
Per DRC inspection of the shop baffle box, no comments were noted.
Used Oil/Kerosene Tank North of Shop Building:
Per DRC inspection of the used oil tank and kerosene tank containment, it appeared that
previous violations concerning spills outside of the containments were addressed, no
additional issues/comments were noted. (Photo l7)
MiIl Processing Areas:
SX Building Roof Drainage:
Comments regarding needed improvements to the SX building roof drain system are ongoing
since 2009. Per the2012 inspection, issues related to the roof drainage and discharges into
the alternate feed circuit have not been addressed. This item will be included as a
confirmatory action item. @hotos 30,31)
Alternate Feed Circuit South of SX Building:
Observations:
DRC noted that a new section of concrete pad was constructed to address issues of temporary
storage of alternate feed drums (Photo 29). Additionally other areas of altemate feed drum
storage outside of the feedstock management area were placed on the newly constructed
concrete pad (Photo 28). DRC has no additional comment/observations regarding the
alternate feed area.
Old Decontamination Pad:
DRC noted that the discharge vault was being drained at the time of the inspection
(Photo 21). DRC has no additional comments regarding the old decontamination pad.
New Decontamination Pad:
10
Observations:
In response to a DRC Notice of Violation concerning the leaking pump-back system
(recirculation system), noted during 2011, DUSA expanded the concrete pad area underneath
the pump, no additional comments were noted.
Reagent Tanks:
Sodium Chloride Tanks - Per past agreements between DRC and DUSA (Agreements
made in 2005) the secondary containment for these tanks is earthen. Per the agreement, all
reagent tanks that pre-existed the Ground Water Permit (3/05) would be acceptable as is -
and that as upgrades or replacements were installed, DUSA would work to meet BAT
requirements. More detail regarding this agreement is in the December 2004 Statement of
Basis, and in Part I.D.3(g). (Photo 1)
Kerosene Tanks (West of Shop) - DUSA has provided concrete foundations for the tanks as
per the 2011 DRC RFI #2 (See Above) and the DUSA l0ll7l20ll Response. (Photos 2)
Secondary containment is earthen under the same agreement as the sodium chloride tanks.
Ammonia Tanks - DRC noted that the tank was undergoing maintenance/refurbishing at the
time of the inspection (sandblasting and re-painting). Secondary containment is earthen per
the same agreement as the sodium chloride tanks. (Photo 4)
Used Oil Tank (shop) - See ShopA/ehicle Maintenance Areas comments above.
Kerosene Tank (shop) - See ShopA/ehicle Maintenance Areas comments above.
Fuel Tanks - Above ground tanks and containment appeared maintained, no additional
comments.
Uranium Liquor Tanks - DRC had no comments regarding tanks or secondary
containment.
Vanadium Pregnant Liquor (VPL) Tanks - The VPL tank steam condensate containment
area, tanks and foundations appeared to be in good condition. (Photo 20)
Clean Water Tank - The construction of an underground pipeline has eliminated the
vegetated ditch and standing water concerns per the 2011 DRC inspection (Photo 24). DRC
did note that water was pooling on the west side of a pumphouse (south of the water tank).
DRC will include repair of the leak as a request for information (Photo 25).
Sulfuric Acid Tank - The tank appeared in good condition (Photo 26).
Propane Tank - Tanks were not inspected during this inspection, note that leaks would be
likely be in gas form.
11
Caustic Soda Tank - Per the2012 inspection it was noted that, in response to Confirmatory
Actions, the caustic acid secondary containment area has been re-poured and that a new tank
is in the process of being installed (Photos 32 and33).
Soda Ash Tanks - The Soda Ash Tanks and Secondary Containment appeared to be in good
condition/repair. DRC has no comments regarding this area. (Photo 34)
Tailings Cells Areas (Note that upland drainage was included in comments above) -
DRC toured the tailings cell areas (Cells 4A and 48 and observed the condition of the outer
toe areas of the dikes to ensure that excessive erosion or damage (e.g. burrowing animal
intrusion or rooting damage) was not present. Although DRC did note some minor burrowing
activities, the dikes appeared to be in overall good condition and sections where rilling was
evident had been re-graded. (Photo 35)

SUBJECT: Observation of conditions following sulfuric acid spill, Denison Mines (USA) Corp.
(DUSA) White Mesa Mill, Blanding, Utah, April 14,2012.
On April 12,2012,I traveled to the DUSA White Mesa mill on behalf of the DRC. While there, I observed
conditions surrounding a sulfi.ric acid release at the Claricone component of the leachate clarification
system.
The Claricone is an upflow sludge blanket clarifier used in various water treatment and chemical processes
to remove precipitated solids from the fluid stream. Fluids enter the Claricone at its base, which in this case
was buried several feet in the ground. Piping introduces the fluid tangential to the cone circumference.
Fluid then travels up the inverted conical shape of the unit, in constantly widening spirals. Near the top of
the cone, the upward component of velocity of the fluid matches the downward velocity of settling
precipitates. Clarified fluid passes over the launder and is directed one way, while solids collect in the
cone, concentrate into a dense sludge blanket, and are drawn off for further treatment.
The influent pipe transporting leachate to the Claricone failed, releasing a large quantity of leachate
solution to the ground at the base of the Claricone. A service tunnel was flooded, and soil at the base of the
Claricone subsided, nearly filling the tunnel with mud. Most of the leachate was recovered and pumped to
Roberts Pond pending final disposal. Some fluid was collected on the ground surface, where most of that
fraction followed a drainage waterway to Roberts Pond. Sulfuric acid content of the release was estimated
to exceed 1000 lbs, and was reportable under RCRA. Calculations were proceeding while I was onsite to
determine the quantity of uranium released in the event.
ln the case of uranium processing, several plants built roughly concurently with the White Mesa mill
incorporated the Claricone in their process trains. Prior to being mothballed or decommissioned, the other
plants had eliminated the Claricone from the process train, inasmuch as the acidic nature of the leachate
prevented precipitation of solids ahead of the Claricone. DUSA plans to bypass and decommission the
Claricone.
DUSA commenced removal of contaminated soil prior to my leaving the site on April 13,2012. Soils were
being placed in Cell4,A..

described in this Proposed Plan based
on the information available at this
time. The final decision on the remedy
to be implemented will be documented
in a Record of Decision (ROD) only after
consideration clf all comments received
and any new information presented.
FOR FURTHER INFORMATION CONTACT:
Questions regarding the SLDS FS/PP
may be directed to Mr. Chris Haskell.

SUPPLEMENTARY INFORMATION:
1, Proposed Action
The U.S. Army Corps of Engineers, St.
Louis District. issued the SLDS
Feasibility Study/Proposed Plan (FS/PP)
for public comment on April 8, 1998.
The site became contaminated as a
result of activities in support ol the
nation's early atomic energy program in
the 1940s. The sites are being addressed
under the Formerly Utilized Sites
Remedial Action Program (FUSRAP).
Cleanup ol these sites is now managed
by the U.S. Army Corps of Engineers.
The alternatives evaluated in the
Feasibility Study are summarized in the
Proposed Plan. Inaccessible soils are not
included as part of the operable unit.
2. Project Alternatives
a. Alternative 1-No Action.
Mandated by the Comprehensive
Environmental Response,
Compensation, and Liabilities
(CERCLA), periodic environmental
r"nonitoring would be conducted, but no
remedial action would be conducted.
b. Altelnative 2-Institutional
Controls and Site Maintenance.
Institutional controls and sitc
maintenance would be implemented to
prevent unacceptable exposures to site
contamination.
c. Alternative 3-Containment.
Alternative 3 incorporates containment,
institutional controls, and
environmcntal monitoring to reduce
further spread ol contaminants and
reduce the potential for direct exposure.
Under this alternative, accessible soils
from SLDS and vicinity properties
would be excavated and consolidated
and capped at a downtown location
such as thc City Property or Plant 2 area.
d. Alternative 4-Partial Excavation
and Disposal. This alternative includes
excavation of accessible soils in the
upper 2 feet to the composite criteria of
5 pCi/g in surface soil (top 6 inches) and
l5 pCi/g in shallow subsurface soil (top
2 feeO (for Ra-226.Ra-228, Th-230, and
Thi-232) and 50 pCi/g for U-238. Site-
specific dose and risk-based target
removal levels ol 50 pCi/g Ra-226, 100
pCi/g Th-230 and 150 pCi/g U-238
would be used for excavation ol soils
bel<lw 2 feet lor most site areas.
e. Alternative 5-Complete
Excavation and Disposal. This
alternative involves excavating soil
contaminated above the composite
criteria regardless of depth.
l. Alternative 6-Selective Excavation
and Dlsposal. This alternative focuses
on reducing the need for future studies,
designs, and remedial actions, in
addition to protection of human health
and the environmental relative to
Alternative 4. It is anticipated that
excavation to the composite criteria
would proceed to a depth ol 6 feet of the
St. Louis Terminal Railroad Association
tracks and the former locations of
Buildings 1 16, I 17, 704-707. Excavation
fbr thc composite critcria would stop at
4 f'cet at all other areas at SLDS
including the vicinity properties and
under the roads.
The Corps of Engineers has identified
alternative 4 as preferred.
3. Scoping Process
Federal, state and local agencies, and
interested individuals are invited to
participate in the scoping process to
determine the range of issues and
alternatives to be addressed. The U.S.
Army Corps of Engineers will hold a
public nreeting to receive oral and
written comments at the Henry Clay
Elementary School Gymnasium, 3820
North 141th Street, St. Louis, Missouri
63107 on April 21, 1998 trom 7:00 p.m.
