During the Quarter, the following DMT monitoring was performed or addressed, as required
under Part I.D.3, I.E.7, and I.F.11 of the GWDP:
• Weekly tailings wastewater pool elevations for tailings Cells 1 and 3 (Part
I.E.7(a));
• Quarterly slimes drain water levels in Cell 2 (Part I.D.3(b)(1) and (2));
• Annual Slimes Drain Compliance (Part I.D.3 (b) and I.F.11);
• Weekly wastewater level measurements in Roberts Pond (Part I.D.3(e) and Part
I.E.7(c));
• Weekly feedstock storage area inspections and inspections of feedstock materials
stored outside of the feedstock storage area (Part I.D.3(t) and Parts I.E.7(d); and
(e));
• Any tailings cell and pond liner system repairs (Part I.E.7 (t) and Part I.E.(8)(c));
• Weekly New Decontamination Pad Inspection (Part I.E.7 (g)) and
• Annual Decontamination Pad Concrete Inspection (Part I.F .11) (not required this
reporting period)
Also during the Quarter, the following Cell 4A and 4B BAT performance standards monitoring
was performed, or addressed, as applicable and as required by Parts I.E.8 and I.E.12 of the
GWDP:
• Leak detection system ("LDS") monitoring for Cell 4A (Part I.E.8.(a)), and Cell
4B (Part I.E.12 (a)); and
• Weekly tailings wastewater pool elevations for tailings Cell 4A (Part I.E.8 (a))
and Cell4B (Part I.E.12 (a)).
1
3.0 WEEKLY TAILINGS WASTEWATER POOL ELEVATION MONITORING
Mill personnel monitored and recorded weekly the elevation of wastewater in the Mill's tailings
cells during the second quarter 2012, to ensure compliance with the maximum wastewater
elevation criteria mandated by Parts I.E.7(a), I.E.8(a) and I.E. 12(a) of the GWDP. The results of
such monitoring, reported as feet above mean sea level ("fmsl"), are included in Attachment A.
Part I.D.2 of the GWDP provides that under no circumstances shall the freeboard of any tailings
cell be less than three feet, as measured from the top of the flexible membrane liner ("FML").
The top of the FML in Cell 1 is at 5,618.5 fmsl, and the top of the FML in Cell 4B is 5600.4
fms!. This means that the maximum wastewater pool elevations in Cells 1 and 4B permitted
under Part I.D.2 of the GWDP are 5,615.5, and 5597.4 fmsl, respectively.
The maximum wastewater pool elevations in Cells 1 and 4B, as measured during the Quarter, are
summarized in the following Table 1. The requirement to meet freeboard elevation limits in Cell
3 and Cell 4A was eliminated as documented on March 14 and 15, 2011 respectively. As
indicated in Table 1, the applicable freeboard limits were not exceeded during the Quarter for
any cell.
All cells also met the maximum wastewater criteria of the Mill's State of Utah Radioactive
Materials License No. UT 1900479 (the "License") throughout the period. However, the
requirements to maintain a minimum freeboard in Cell 3 and Cell 4A were removed by the
Director of the Utah Division of Radiation Control (the "Director") during the first quarter of
2011 as detailed below.
Condition 10.3 of the License provides that the freeboard limit for Cell 1 shall be set in
accordance with procedures that have been approved by the U.S. Nuclear Regulatory
Commission ("NRC"). Under those procedures the freeboard limit for Cell 1 is set as per the
January 10, 1990 Drainage Report for CellI at a liquid maximum elevation of 5,615.4 fms!.
Condition 10.3 of the License also provides that the freeboard limit for Cells 3, 4A and 4B shall
be recalculated annually in accordance with the procedures approved by the Director. A letter
from the Director dated January 27, 2011 which approved the use of Cell 4B and a subsequent
letter dated March 14, 2011, stated that authorization of the use of Cell 4B and approval of the
DMT and Cell 4A Operations and Maintenance ("O&M") Plans effectively eliminated the
former freeboard elevation requirements for tailings Cell 3. The approvals of the DMT and Cell
4A O&M Plans also resolved previous freeboard exceedance issues and further stated that
former issues regarding the freeboard exceedances for Cell 3 are closed-out. Pursuant to the
receipt of the March 14, 2011 letter, freeboard elevation survey measurements in Cell 3 were no
longer required or conducted.
A letter from the Director dated January 27, 2011 which approved the use of Cell 4B and a
subsequent letter dated March 15, 2011, stated approval of the DMT and Cell 4A and Cell 4B
Operations and Maintenance ("O&M") Plans effectively eliminated the former freeboard
elevation requirements for tailings Cell 4A. The approvals of the DMT and Cell 4A and 4B
O&M Plans also resolved previous freeboard exceedance issues and further stated that former
2
issues regarding the freeboard exceedances for Cell4A are closed out. Pursuant to the receipt of
the March 15, 2011 letter, freeboard limits in Cell 4A were no longer required. The solution
elevation measurements in Cell4A are not required for compliance with freeboard limits but are
required for the calculation of the daily allowable volume of fluids pumped from the Cell 4A
LDS, are collected for this purpose.

* The Director approved the removal of the Cell 3 freeboard limit and authorized the use of Cell 4 B on January 27,
2011. Cell 3 is nearly full of solids, and is undergoing pre-closure steps.
** The Director granted a variance from the Cell4A freeboard limit on January 13,2011, and approved the removal
of the Cell 4A limit and authorized the use of Cell 4B on January 27, 2011. The previous freeboard limit noted
above for Cell4A was not set out in the License. The freeboard limit of 5,593.74 for Ce1l4A was set out in a letter
from the Director dated November 20,2008. The approved DMT Plan, Revision11.1 dated January 2011, included
the removal of the freeboard limit for Ce1l4A to be replaced by a freeboard limit for Ce1l4B that will accommodate
the freeboard requirements of Cells 1, 4A, and 4B.
4.0 QUARTERL Y SLIMES DRAIN WATER LEVEL MONITORING
4.1 General
Part I.D.3(b)(l) of the GWDP provides that the Permittee shall at all times maintain the average
wastewater recovery head in the slimes drain access pipes of each of Cells 2 and 3 to be as low
as is reasonably achievable, in accordance with the DMT Plan. Part I.D.3(b )(3) of the GWDP
provides that for Cell 3, this requirement shall apply after initiation of dewatering operations.
Part I.D.6(c) of the GWDP provides that, after the Permittee initiates pumping conditions in the
slimes drain layer in Cell 4A, the Permittee will provide: 1) continuous declining fluid heads in
the slimes drain layer, in a manner equivalent to the requirements found in Part I.D.3(b), and 2) a
maximum head of 1.0 feet in the tailings (as measured from the lowest point of the upper FML)
in 6.4 years or less. Similarly, Part I.D.13(c) of the GWDP provides that, after the Permittee
initiates pumping conditions in the slimes drain layer in Cell 4B, the Permittee will provide: 1)
continuous declining fluid heads in the slimes drain layer in a manner equivalent to the
requirements found in Part I.D.3(b), and 2) a maximum head of 1.0 feet in the tailings (as
measured from the lowest point of the upper FML) in 5.5 years or less.
3
The GWDP, dated July 14, 2011, Part I.D.3 (b)(2) states "effective July 11, 2011, the Permittee
shall conduct a quarterly slimes drain recovery test. .. ". Monthly testing was conducted through
the second quarter of 2011. The frequency change dictated by the GWDP was implemented in
the third quarter 2011. The test ensures that each tailings cell meets the following minimum
requirements: 1) includes a duration of at least 90-hours, as measured from the time that
pumping ceases, and 2) achieves a stable water level at the end of the test, as measured by three
consecutive hourly water level depth measurements with no change in water level, as measured
to the nearest 0.01 foot.
At this time, dewatering operations have not commenced in Cell 3, Cell 4A, or Cell 4B. As a
result, the requirements in Part I.E.7(b) to monitor and record monthly the depth to wastewater in
the slimes drain access pipes as described in Part I.D.3 of the GWDP apply only to Cell 2 at this
time. Accordingly, this Report is limited to slimes drain recovery head information relating to
Cell 2 only.
Pursuant to Parts I.E.7(b) and I.F.2 of the GWDP, Section 8.2 of the DMT Plan and
correspondence from DRC, dated February 7, 2008, the results of quarterly recovery monitoring
of the slimes drain for Cell 2 are to be recorded and included with the results of quarterly
monitoring in the quarterly White Mesa Mill DMT Performance Standards Monitoring Report
and Cell 4A and Cell 4B BAT Performance Standards Monitoring Reports (the "DMT Reports").
Further, beginning in 2008, quarterly DMT Reports must include both the current year values
and a graphic comparison to the previous year. The annual slimes drain recovery head report for
2012, which addresses the requirements of Part I.F.11 of the GWDP and Section 8.2 of the DMT
Plan, will be included in the 4th quarter 2012 DMT Report.
The requirement in Section 3.1(b)(v) of the DMT Plan to monitor the depth to wastewater in the
Cell 2 slimes drain access pipe weekly to determine maximum and minimum fluid head is a
requirement of the License, is not a DMT performance monitoring standard required by Parts
I.D.3 or I.E.7 of the GWDP, and hence is not required to be included in the routine DMT
Performance Standards Monitoring Report under Part I.F.2 of the GWDP. EFR has included, in
Attachment C, the information requested by DRC for completeness, as noted in the EFR letter
dated November 14, 2011. However, as stated in the November 14, 2011 letter, EFR revised the
DMT Plan by preparing two separate plans for the GWDP and the License requirements and
submitted the revised plans on July 25, 2012. EFR received DRC approval of the plans on
August 6, 2012. EFR will provide quarterly DMT reports addressing the GWDP DMT
requirements beginning with the third quarter 2012.
4.2 Results for the Quarter
In accordance with these requirements, the quarterly slimes drain recovery head monitoring data
for the Quarter, which includes the date and time for the start and end of the recovery test, the
initial water level, and the final depth to stable water level, as well as a weekly summary data
table for the slimes drain head measurements for the Quarter required under the License, are
included as Attachment C to this Report.
4
4.3 Quality Assurance Evaluation and Data Validation
EFR management has evaluated all slimes drain data collected, data collection methods, and all
related calculations required by the GWDP, and have verified the accuracy and reliability of both
the data and calculations reported.
As a result of its quality assurance evaluation and data validation review, EFR has concluded that
all of the 2009, and 2010 monthly slimes drain tailings fluid elevation measurements and the
2011 monthly (through June) and quarterly (July forward) slimes drain tailings fluid elevation
measurements to date meet the test performance standards found in Part I.D.3(b )(2) of the
GWDP and can be used for purposes of determining compliance with the requirements of Part
I.D.3(b)(2) of the GWDP.
4.4 Graphic Comparison to Previous Year
A graph showing the final depth to stable water level readings for each month in 2009 through
first quarter 2012 (quarterly beginning in July 2011), for which validated data is available (see
Section 4.3 above), is included as Attachment D, which shows a graphic comparison of this
Quarter's data to data for 2009,2010, 2011 and 2012.
5.0 WEEKL Y WASTEWATER LEVEL MONITORING: ROBERTS POND
During the Quarter, Mill personnel monitored and recorded weekly the wastewater levels at
Roberts Pond to determine compliance with the DMT operations standards in Part I.D.3( e) of the
GWDP. Part I.D.3(e) of the GWDP provides that the water level in Roberts Pond shall not
exceed an elevation of 5,624 fmsl.
The maximum wastewater elevation measured in Robert's Pond during the quarter was 5,619.94
fmsl, which did not exceed the maximum permitted elevation of 5,624 fmsl. The results of such
monitoring are included in Attachment A.
6.0 WEEKL Y FEEDSTOCK STORAGE AREA INSPECTIONS AND INSPECTIONS
OF FEEDSTOCK MATERIAL STORED OUTSIDE THE FEEDSTOCK STORAGE
AREA
Weekly feedstock storage area inspections were performed by the Mill's Radiation Safety
Department, to confirm that the bulk feedstock materials are stored and maintained within the
defined area described in the GWDP and that all alternate feedstock located outside the defined
feedstock area is maintained within containers that comply with the requirements of Part I.D.11
of the GWDP. The results of these inspections are recorded on the Weekly Mill Inspection
forms, which are available at the Mill for inspection. No issues were noted during the weekly
inspections.
5
7.0 TAILINGS CELLS AND POND LINER SYSTEM REPAIRS
The liner systems at Cells 1, 2, 3, 4A, and 4B were inspected on a daily basis pursuant to the
requirements of Sections 2.1 and 2.2 of the Mill's DMT Plan. The results of those inspections
are recorded on the Mill's Daily Inspection Data sheets, which are available at the Mill for
review. A visual inspection of Roberts Pond was performed on a weekly basis. The results of
those inspections are recorded on the Weekly Mill Inspection forms, which are available at the
Mill for review.
In accordance with Part LE.7(f) of the GWDP, in the event that any liner defect or damage is
identified during a liner system inspection, the Mill shall immediately implement the currently
approved Liner Maintenance Provisions. Further, Part LF. 2 of the GWDP provides that when a
liner repair is performed at any tailings cell or at Roberts Pond, a Repair Report shall be prepared
and included with the next quarterly DMT report.
Mill personnel detected an accumulation of fluid in the LDS standpipe of Cell 1 on Wednesday,
June 2, 2010. Transfer of fluids from Cell 1 to Cell 4A to lower the Cell 1 level sufficiently to
detect and repair any damage began on June 2,2010. Maintenance identified some FML damage
and performed repairs during the period when the level was lowest. Following the repairs, the
level was allowed to gradually return to its June 3 level of 5614.57 feet and the LDS remained
dry until, after a period of heavy rains in late July and early August (and an increase in the
solution in level in Cell 1), a recurrence of the LDS liquid level was identified on August 7,
2010. At that time, the Mill resumed pumping Cell 1 to Cell4A to lower the solution level.
During discussions on August 12, 2010, DRC personnel agreed with EFR that both the June and
August identifications of LDS solutions were part of one event. The temporary cessation of flow
into the LDS between June and August detections may have resulted from lowering the solution
level to a point below some tears or damage that were not identified during the July repair
efforts. EFR submitted to DRC a plan and schedule for inspection and repair, if necessary, of the
inside slope areas of the Cell 1 FML above the 5613 foot level, on August 18, 2010, and an
updated plan on August 30, 2010. DRC conditionally approved the updated plan in a letter
dated September 22, 2010. The updated plan committed to completion of the repairs by July 31,
2012.
The September 22, 2010 DRC letter and Part l.F.2 of the GWDP require that the repairs be
documented in a liner repair report which shall be included with the next quarterly DMT report,
that is, in the DMT Report following completion of the repairs to be reported. Repairs were
completed in June 2012. Consistent with Part I.F.2 of the GWDP EFR has included the required
repair report as Tab E of this DMT report.
Consistent with the approved repair plan and schedule, repairs to the Cell 1 FML were conducted
during the months of September and October 2010, and ceased during the months of November
and December 2010. Repairs to the Cell 1 liner resumed in April 2011 and stopped in October
2011 for the winter. Repairs to the Cell 1 liner resumed again in April 2012 and were completed
in June 2012.

8.0 DECONTAMINATION PADS
8.1 Summary of Weekly Inspections
Part I.F.7 (g) of the GWDP and Section 3.1 of the DMT Plan require that a weekly inspection of
the New Decontamination Pad be performed, and that the vertical inspection portals on the New
Decontamination Pad which are located between the primary and secondary containments be
visually observed on a weekly basis as a means of detecting any leakage from the primary
containment into the void between the primary and secondary containments. The BAT
performance standards for the New Decontamination Pad are set out in Part I.D .14 of the
GWDP. The New Decontamination Pad was placed into service on March 22, 2010. Use of the
New Decontamination Pad was temporarily suspended during the second quarter 2010 as a result
of a cease and desist order from DRC dated May 18, 2010. Because the New Decontamination
Pad was not in use after the second quarter 2010, the weekly inspections of the containments
were stopped for the remainder of 2010. The Executive Secretary provided authorization for use
of the New Decontamination Pad in a letter dated February 1, 2011. Use of the New
Decontamination Pad resumed in February 2011 and the weekly inspections were resumed as
required.
Table 2 below indicates the water level measurements in each portal measured during the second
quarter 2012.

As can be seen from the foregoing table, no fluids were observed to be present in any of the
portals during the quarter.
Any soil and debris identified during the weekly inspections was removed from the wash pad of
the New Decontamination Pad, in accordance with part I.D.14 (a) of the GWDP and Section 3.1
(e)(i)(F) of the DMT Plan. No cracks greater than 1/8" were observed during any weekly
inspections.
8.2 Annual Inspection of Existing Decontamination Pad
The Existing Decontamination Pad was taken out of service and inspected during the second
quarter on April 6, 2012, to ensure the integrity of the steel tank, as required by Part I.H.5(c) of
the Permit and Section 6.5 of the DMT Plan. No significant cracks (greater than 1/8 inch),
deterioration or damage were identified. A few minor cracks (less than 1/8 inch) were observed.
Repairs and maintenance, including caulking and sealing of cracks, were completed on April 7,
2012 to prevent additional deterioration. The decontamination pad was placed back into service
after the completion of the repair and maintenance activities.
The inspection report and photos taken during the inspection are provided in Attachment G-1.
8.3 Annual Inspection of New Decontamination Pad
As previously stated, the New Decontamination Pad was placed into service on March 22, 2010.
Use of the New Decontamination Pad was temporarily suspended as a result of a cease and desist
order from DRC dated May 18,2010. DRC's approval for use of the New Decontamination Pad
was granted on February 1, 2011, following submittal of revisions to the DMT Plan and DRC
observation of hydrostatic testing of the in-ground water holding tanks. Revisions to the DMT
Plan were submitted by Denison on November 12, 2010 and reviewed by DRC. Hydrostatic
testing was re-performed from November 24 to 26, 2010 following a 10-day advanced notice to
DRC on November 12, 2010. The Executive Secretary provided an authorization for use of the
New Decontamination Pad in a letter dated February 1,2011. Use of the New Decontamination
Pad resumed in February 2011.
The New Decontamination Pad was taken out of service and inspected on April 6, 2012 to ensure
integrity of the wash pad's exposed concrete surface, as required by Part I.F.12 of the GWDP
and Section 6.5 of the DMT Plan. No abnormalities were identified. No significant cracks
(greater than 1/8 inch), deterioration or damage were identified. A few minor cracks (less than
1/8 inch) and small areas of surface abrasions were observed. These minor cracks and the
surface abrasions were repaired on April 7, 2012 to prevent additional deterioration, even though
the repairs are not required by the GWDP.
The inspection report and photos taken during the inspection are provided in Attachment G-2.

This Section constitutes the routine Cell 4A and Cell 4B BAT Performance Standards
Monitoring Report for the Quarter, as required under Part I.F.3 of the GWDP.
9.1 LDS Monitoring
9.1.1 Operational Status of LDS Pumping and Monitoring Equipment
The LDS pumping and monitoring equipment for each of Cell 4A and Cell 4B, including, but not
limited to, the submersible pump, pump controller, head monitoring, and flow meter equipment,
operated continuously during the Quarter.
Ce1l4A
During the Quarter, there were no failures of any pumping or monitoring equipment not repaired
and made fully operational within 24-hours of discovery, as contemplated by Part I.E.8(a)(l) for
CeIl4A.
Ce1l4B
During the Quarter, there were no failures of any pumping or monitoring equipment not repaired
and made fully operational within 24-hours of discovery, as contemplated by Part I.E.I2(a)(l)
for CeIl4B.
9.1.2 Measurement of Weekly Fluid Head at the Lowest Point in the Secondary FML
The readings pertaining to the fluid head above the lowest point in the secondary FML for Cells
4A and 4B are provided in Attachment F.
As can be seen from a review of Attachment F, at no point in the Quarter did the fluid head in the
Cell 4A LDS sump exceed a I-foot level above the lowest point in the lower FML on the Cell
floor (where for purposes of compliance monitoring this I-foot distance equates to 2.28 feet
[27.36 inches] above the LDS system transducer), as stipulated by Part I.E.8(a)(2) of the GWDP.
During the Quarter, the fluid head in the Cell 4A LDS sump did not exceed 12.2 inches above
the LDS transducer.
As can be seen from a review of Attachment F, at no point in the Quarter did the fluid head in the
Cell 4B LDS sump exceed a I-foot level above the lowest point in the lower FML on the Cell
floor, as stipulated by Part I.E.I2(a)(2) of the GWDP. For the purposes of compliance
monitoring this I-foot distance equates to 2.25 feet (27 inches) above the LDS system. During
the quarter the fluid head in Cell4B sump did not exceed 2.13 inches above the LDS transducer.
9.1.3 Measurement of the Volume of Fluids Pumpedfrom the LDS
9
The readings pertaining to the volume of fluids pumped are provided in Attachment F.
Cell4A
As can be seen from a review of Attachment F, 5,529 gallons of fluid were pumped from the Cell
4A LDS for the second quarter of 2012. Based on this, the average daily LDS flow volume in
Cell4A did not exceed 24,160 gallons/day, as stipulated by Part I.E.8(a)(3) of the GWDP.
Daily allowable volume of fluids pumped from the Cell 4A LDS have also been calculated based
on weekly tailings cell fluid measurements using the calculations provided in the Cell 4A BAT
Operations and Maintenance Plan. A letter from the Director dated January 27, 2011 which
approved the use of Cell4B, and a subsequent letter dated March 15, 2011, stated approval of the
DMT and Cell 4A Operations and Maintenance ("O&M") Plans and effectively eliminated the
former freeboard elevation requirements for tailings Cell 4A. Pursuant to the receipt of the
March 15, 2011 letter, freeboard limits in Cell 4A were no longer required. However, the
weekly wastewater elevations were completed in order to calculate the maximum daily allowable
flow volume, based on in the Cell 4A BAT Operations and Maintenance Plan. Based on the
wastewater pool elevation surveys conducted during the quarter, and the maximum head
recorded on the FML during the Quarter of approximately 37 feet, the allowable flow rate would
be approximately 604.0 gallons/acre/day, as determined under the Mill's Cell 4B BAT
Operations and Maintenance Plan, Table 1A (also included in Attachment F of this report), and
assuming a liner elevation of 5555.55 feet and approximately 40 acres of liquid area. The
average daily flow volume in Cell 4A did not exceed the calculated flow volume of 24,160
gallons/day. As mentioned above, during second quarter of 2012, 5,529 gallons of fluid were
pumped from Cell 4A LDS during the period and did not exceed the calculated flow volume.
The second quarter allowable flow rate calculation for Cell 4A is included in Attachment F of
this report.
Cell4B
As can be seen from a review of Attachment F, no fluids were pumped from the Cell4B LDS for
the second quarter of 2012 and the flowrate is therefore below the 26,145 gallons/day limit, as
stipulated by Part I.E. 12(a)(3) of the GWDP.
Based on the wastewater pool elevation surveys conducted during the quarter, the maximum
head recorded on the FML during the Quarter was approximately 24 feet. The allowable flow
rate would therefore be approximately 475.6 gallons/acre/day, as determined under the Mill's
Cell4B BAT Operations and Maintenance Plan, Table 1B (also included in Attachment F of this
report), and assuming a liner elevation of 5557.5 feet and approximately 36.17 acres of liquid
area. The average daily flow volume in Cell 4B did not exceed the calculated flow volume of
17,202 gallons/day. During second quarter 2012, no fluids were pumped from Cell4B LDS and
therefore did not exceed the calculated flow volume. The second quarter allowable flow rate
calculation for Cell 4 B is included in Attachment F of this report.
10
9.2 Measurement of Weekly Wastewater Fluids in Cells 4A and 4B
Weekly fluid elevations for Cells 4A and 4B for the quarter are provided in Attachment A along
with elevations for Cell 1 and Roberts Pond.
9.3 Slimes Drain Recovery Head Monitoring
As the Mill has not initiated pumping conditions in the Cell4A or Cell4B slimes drain system at
this time, monthly recovery head tests and fluid level measurements are not required to be made
at this time pursuant to Part I.E.8(b) of the GWDP.
10.0 CELL 1 AND CELL 3 LDS MONITORING FOR THE QUARTER
The requirement in Section 3.1(a) of the DMT Plan to monitor the LDS for Cells 1 and 3 is a
requirement of the License, is not a DMT performance monitoring standard required by Parts
I.D.3 or LE.7 of the GWDP, and hence is not required to be included in the routine DMT
Performance Standards Monitoring Report under Part LF.2 of the GWDP. EFR has included in
Attachment F the information requested by DRC for completeness, as noted in the EFR letter
dated November 14, 2011. However, as stated in the November 14, 2011 letter, EFR revised the
DMT Plan by preparing two separate plans for the GWDP and the License requirements and
submitted the revised plans on July 25, 2012. Approval of the plans was received by EFR on
August 6, 2012. EFR will provide quarterly DMT reports addressing the GWDP DMT
requirements only beginning with the third quarter 2012.
10.1 Operational Status of LDS Pumping and Monitoring Equipment
The LDS pumping and monitoring equipment for each of Cells 1, and 3, including, but not
limited to, the submersible pump, pump controller, head monitoring, and flow meter equipment,
operated continuously during the Quarter.
For Cell 1, during the Quarter, there were no failures of any pumping or monitoring equipment
not repaired and made fully operational within 24-hours of discovery.
For Cell 3, during the Quarter, there were no failures of any pumping or monitoring equipment
not repaired and made fully operational within 24-hours of discovery.
10.2 Measurement of the Volume of Fluids Pumped from the LDS
No fluids were pumped from the Cell 1 or 3 LDSs during the quarter because no fluids were
detected in either the Cell 1 or Cell 3 LDS.
11
10.3 Measurement of Weekly Wastewater Fluids in Cells 1, and 3
A summary of the fluid elevations for the Cell 1 and 3 LDSs for the quarter are provided in
Attachment F. The LDS for Cells 1 and 3 were dry during the quarter.
10.4 Slimes Drain Recovery Head Monitoring
As the Mill has not initiated pumping conditions in the Cell 1 or Cell 3 slimes drain system at
this time, monthly recovery head tests and fluid level measurements are not required to be made
at this time.
11.0 ANNUAL SLIMES DRAIN RECOVERY HEAD REPORT FOR THE
CALENDAR YEAR 2012
The annual slimes drain recovery head report for Cell 2 for calendar year 2012 (the "Period"), as
required under Parts I.D.3 (b) and I.F.11 of the GWDP and Section 8.2 of the DMT Plan will be
included with the 4th quarter DMT report which will be submitted on or before March 1, 2013.

1 The freeboard limit as permitted under License condition 10.3 is no longer applicable to Cell 3 or CeIl4A.
2Cell 3 is nearly full of solids, and is undergoing pre-closure steps. The freeboard limit specified here is no longer
required and the weekly measurements are no longer required per the January 27 and March 14, 2011 letters from
DRC.
3 The freeboard limit for Cell4A is not set out in the License. The freeboard limit of 5,593.74 for Cell4A is set out
in a letter from the Executive Secretary dated November 20,2008. Denison proposed in the DMT Plan revision
dated November 12,2010 the removal of the freeboard limit for Cell4A to be replaced by a freeboard limit for new
Cell4B that will accommodate the freeboard requirements of Cells 2,3, 4A, and 4B. The Executive Secretary
granted a variance from the Ce1l4A freeboard limit on January 13,2011 and approved the removal of the Ce1l4A
limit and the use of Cell 4B on January 27, 2011. The weekly measurements are no longer required for compliance
with freeboard limts, but are required to calculate the daily permissable leakage rate for CeIl4A.
4 The freeboard limit listed is the value specified in the DMT plan when the pool surface area is 40 acres. A pool
surface area of 40 acres is used because there are no beaches present in Ce1l4B at this time.

1. INTRODUCTION
Energy Fuels Resources (USA) Inc. ("EFR"), formerly named Denison Mines (USA) Corp., operates
White Mesa Mill (the "Mill") Tailings Cell 1 as the Mill's primary liquid evaporation basin.
Performance standards, monitoring and maintenance requirements for Tailings CellI are specified in
the Discharge Minimization Technology requirements in the Mill's Groundwater Discharge Permit
(the "Permit").
Per Part I.F.3 of the Mill's Permit, if EFR identifies any damage to the liners of any tailings cell or
Roberts Pond, EFR is required to repair the damage in accordance with the Mill's Liner Maintenance
Provisions, and provide a tailings cell liner Repair Report to the Director of the Division of
Radiation Control.
EFR performed repairs to the Cell 1 Flexible Membrane Liner ("FML") during the period from June
2010 to June 4,2012, as discussed below. As a result of those repairs, this Tailings Cell 1 Liner
Repair Report (the "Report") is being submitted to comply with the Mill's Liner Maintenance
Provisions, Revision 1, dated October 18, 2009 and with Part I.F.2 of the Mill's Radioactive
Materials License (RML"). The Liner Maintenance Provisions require that the Repair Report be
signed by a Utah licensed professional engineer and contain the following information:
• Repair narrative describing the nature of the damage and the repair work completed to repair
the damage.
• Repair material type used to complete the repair
• Repair material description
• Post repairs test specIfications
• Test Methods (ASTM D5641)
• Daily reports during the repair work
• Repair test results
• Quality Assurance/Quality Control Information
Accordingly, the sections of this Repair Report, below, are organized consistent with the items
above.
Part I.F.2 of the RML requires that following the repairs, the
"Repair Report shall be included with the next quarterly DMT Report".
Repairs resulting from the event above were completed during the third quarter of20 12. This Repair
Report has been included with the second quarter 2012 DMT Report, being submitted on September
1,2012.

Due to Senate Bill 21 of the 2012 Utah Legislative Session, references to the Executive Secretary of
the Utah Radiation Control Board in the Utah Radiation Control Act have been modified to refer to
the Director of Radiation Control. This Report and the correspondence in its appendices utilize both
titles interchangeably.
2. INCIDENT HISTORY AND CHRONOLOGY
EFR detected solutions in the Cell 1 LDS on June 7, 2010. EFR provided verbal notice to the
Director on June 3, 2010 and written notice on June 7, 2010 (provided in Appendix 1). EFR then
lowered the solution level in Cell 1 to allow inspection and initial repairs, which were conducted
during June and July 2010. After raising the solution level following the repairs, EFR detected
solutions in the LDS on August 7,2010. During a telephone conference call on August 12,2010, the
Director and EFR concurred that both occurrences of solution in the LDS were part of one event,
specifically, that the inspection and repairs conducted in June and July 2010 had not identified all the
damaged areas requiring repair.
EFR submitted a Plan and Schedule for Cell 1 Inspection and Repairs to the Director on August 18,
2010 (Appendix 1). EFR's plan proposed to:
• reduce the solution level to approximately 5613 feet amsl
• identify, inspect, and repair the areas of Cell 1 with the highest likelihood of damage,
• allow the solution level to recover to pre-June 2010 levels (above 5613 feet amsl) and
confirm that solutions do not reappear in the LDS.
DRC and EFR discussed three additional DRC concerns in a conference call on August 23,2010. In
response to these concerns, DRC's September 22, 2010 Conditional Approval and Confirmatory
Action letter (Appendix 1) required that EFR:
• Submit written findings regarding the root cause of the Cell 1 leakage by September 30,
2012,
• Video log the Cell 1 standpipe, determine the total downslope distance, remove debris, and
repeat the videolog if necessary, and
• Inspect and repair the Cell 1 liner across all inside slope areas above 5,613 feet amsl before
July 31, 2012.
EFR submitted a revised repair plan on August 30,2010 (Appendix 1), addressing DRC's additional
concerns. Videolog results for both CellI and Cell 3 were submitted under separate cover and are
not addressed in this Repair Report. The root cause analysis is reiterated below.
3. ROOT CAUSE ANALYSIS
EFR's June 7, 2010 and August 18,2010 letters to the Director committed that the repair report
N:\Celll Plan and Repairs 201O\Cell 1 Repair Reports\Celll Liner report for DMT Q2 2012\Cell 1 Repair Report to Drctr 09.01.12.doc
White Mesa Mill -Repair Report, Tailings Cell I Page 5 of 16
would document the root cause analysis performed during July and August 2010. The root cause
analysis is provided below, following a description of Cell l' s design elements.
Description of Cell 1
Cell 1 consists of the following major design elements:
• Cross-valley Dike and East Dike -constructed on the south side of the pond of native
granular materials with a 3: 1 slope, a 20-foot crest width, and a crest elevation of about 5,620
ft above mean sea level (amsl). A dike of similar design was constructed on the east margin
of the pond, which forms a continuous earthen structure with the south dike. The remaining
interior slopes are cut-slopes at 3: 1 grade.
• Liner System -including a single 30 mil PVC flexible membrane liner (FML) constructed of
solvent welded seams on a prepared sub-base. The top elevation of the FML liner was
5,618.5 ft amsl on both the south dike and the north cut-slope. A protective soil cover layer
was constructed immediately over the FML with a thickness of 12-inches on the cell floor
and 18-inches on the interior sideslope.
• Crushed Sandstone Underlay -immediately below the FML a nominal 6-inch thick layer of
crushed sandstone was prepared and rolled smooth as an FML sub-base layer. Beneath this
underlay, native sandstone and other foundation materials were graded to drain to a single
low point near the upstream toe of the south cross-valley dike. Inside this layer, an east-west
oriented pipe was installed to gather fluids at the upstream toe of the cross-valley dike.
As a result of the protective soil layer overlying CellI's FML, any tears or damage to seams or liner
surfaces, are not readily visible.
Root Cause Analysis
As discussed in the August 18,2010 letter, the root cause of the Cell 1 leakage was the defects and
damage (tears) identified in the Cell 1 FML material along the inside slope of the cell at elevations
above 5613 feet amsl. The defects and damage to the liner may have resulted from age, exposure, or
normal wear and tear over the 30-year life of the cell's FML. Tears and damage are less likely to
occur at location on the FML below 5613 feet amsl because the area above this elevation is exposed
to
• more traffic (for sampling, monitoring, and other activities),
• more effects of discharge hoses and solution transfer, and
• more weathering (including wet/dry conditions),
than areas lower down along the sidewalls of the cell's FML.
N:\Celi 1 Plan and Repairs 201O\Celi 1 Repair Reports\Cell 1 Liner report for DMT Q2 20 12\Cell 1 Repair Report to Drctr 09.01. 12.doc
White Mesa Mill-Repair Report, Tailings Cell 1 Page 6 of 16
At the time the LDS level was first noted on June 3, the Cell 1 solution level was approximately
5614.57 feet amsl. The Mill lowered the CellI solution level to 5613.4 feet amsl during the month
of June to allow inspection and repair of damage to the CellI FML. Maintenance performed repairs
during the period when the level was lowest and the Cell 1 liquid level was subsequently allowed to
return to its June 3 level.
/
The Mill experienced periodic heavy rains in late July and early August. During the August 7, 2010
tailings inspection, the Cell liquid level had reached 5614.22 feet amsl. At that time, the
Environmental Technician identified that the LDS again had an observable liquid level. The second
identification of leakage solutions in the Cell 1 LDS, indicated that the inspection and repairs
performed on the CellI FML in June and July were apparently not successful in identifying all of the
tears or damage.
The temporary cessation of flow into the LDS between the June and August Cell 1 LDS fluid
detections may have resulted from the lowering of the solution level to a point below the remaining
tears or damage to the FML. However, as the solution level in CellI rose, it reached the elevation of
one or more remaining defects in the liner, resulting in the recurrence of solutions in the LDS system.
4. SOLUTION ACCUMULATION RATE ESTIMATES
Condition 11.3 A of the Mill's RML requires that
"If fluid is pumped form an LDS, the licensee shall calculate the flow rate by
dividing the recorded volume of fluid recovered by the elapsed time since fluid was
last pumped or increases in the LDS fluid levels were recorded, whichever is the
more recent. The licensee shall document the results of this calculation."
EFR's August 18,2010 plan and schedule letter to the Director committed that the Report
would provide data used in estimation of solution accumulation rate. The data was initially
provided in EFR's letter to DRC dated September 30, 2010 and clarified and corrected in
EFR's letter to DRC of November 11 , 2010. Flow rate calculations from EFR's letter of
November 11,2010 are provided in the tables in Appendix 2.
5. SOLUTION CHARACTERIZATION DATA
Condition 11.3 B of the Mill's Radioactive Materials License requires that:
"Upon the initial pumping of fluid from an LDS, the licensee shall collect a fluid
sample and analyze the fluid for pH and the parameters listed in paragraph A of this
license conditions. The licensee shall determine whether the LDS fluid originated
from the constituents listed in paragraph A of this license condition or has a pH level
N:\Cell 1 Plan and Repairs 201O\Cell 1 Repair Reports\Celll Liner report for DMT Q2 2012\Cell 1 Repair Report to Drctr 09.01.12.doc
White Mesa Mill-Repair Report, Tailings Cell 1 Page 7 of 16
less than 5.0. If either elevated constituent levels or a pH less than 5.0 is observed,
the licensee shall assume that the disposal cell is the origin of the fluid."
EFR concluded, from pH paper tests indicating pH less than 5 on June 2 and August 7,2010, that the
solutions in the CellI LDS on both occasions were tailings fluids. The Mill collected samples from
the LDS solutions on June 3 and August 8, 2010.
EFR's August 18, 2010 plan and schedule letter to the Director committed that EFR would provide
any laboratory analyses/ characterization data used to supplement the initial conclusion, based on the
pH paper tests, that the solutions discovered in the Cell 1 were tailings solution. Analytical data
from Energy Laboratories and America West Analytical Laboratories is provided in Appendix 3.
6. REPAIR NARRATIVE
As discussed above, CellI contains a single 30 mil PVC FML constructed of solvent welded seams,
overlain by a protective soil cover layer of 12-inches on the cell floor and 18-inches on the interior
side slope.
Repairs to the CellI FML occurred during the period from June 2010 to June 4, 2012, as indicated
on the daily repair reports in Appendix 4. Inspection and repair of Cell 1 proceeded in a counter-
clockwise direction around the interior slope. Repairs required hiring and on-the-job training of
additional personnel for seven man labor crews (including one supervisor) to perform the following
steps:
• Removal of the soil cover in sections around the perimeter,
• Visual inspection of each uncovered section of the FML,
• Installation of repair patches over each damaged location,
• Vacuum testing of each installed repair patch, and
• Replacement and/or regluing and retesting of repaired areas if necessary.
The liner was patched with sections cut from 30 mil PVC roll stock supplied by Colorado Lining,
Inc. Prior to placement of the new lining material repair patch, the soil surface was compacted and
swept clean of any protruding rocks that might damage the lining material. Prior to seaming, the
lining material was cleaned with methyl ethyl ketone (MEK). The liner was then seamed using an
adhesive supplied by Colorado Lining, Inc. The repaired seams were then 100% vacuum box tested
according to the procedures in the attached report. Testing results are included in the attached daily
reports of the repair activities. The final repair activities involved the replacement of the soil cover in
order to protect the lining material from exposure to UV degradation.
DRC's September 24,2010 Conditional Approval and Confirmatory Action letter required
that:
"The Cell 1 liner would be checked and repaired fully and completely across all

inside side slope areas above 5,613 feet amsl on or before July 31,2012."
In compliance with that requirement, EFR completed the inspection and all repairs to the liner inside
slope areas above 5,613 feet amsl on June 4, 2012.
7. REPAIR MATERIAL TYPE AND DESCRIPTION
Vacuum testing used the following equipment:
• soapy water solution
• vacuum check sheets
• vacuum testing equipment (vacuum box) consistent with ASTM Standard D5461.
Liner repairs used the following equipment:
• Personnel protective equipment appropriate for protection from cell solutions and safety
along banked sidewalls of the cell
• Various sized sections of 30 mil black PVC liner material
• PVC to PVC adhesive glue
• methyl ethyl ketone (,2-butanone" or "MEK") as a surface and glue cleaner
• sandbags
• wire brushes
• paint brushes and paint rollers to apply PVC glue
• TSP/Manu-Tech Service Projects vacuum testing device (referred to as the "vacuum box")
• Liner Daily Repair Forms
8. POST-REPAIR TEST SPECIFICATIONS AND TEST METHODS
As mentioned above, each repaired location was tested using a "vacuum box" and soapy water to
identify any remaining leaks by observation of air bubbles through the repair seam.
Tests were conducted in accordance with ASTM Standard D5461 utilizing the Manu-tech Service
Projects vacuum box referred to above. Per this standard, tests were conducted such that test areas
overlapped by at least 10% of the minimum vacuum chamber length or at least 2 inches, whichever
is greater, until the entire seam was tested. Per D5461, 4 to 8 psi vacuum was applied and the seam
was observed for air bubbles. If any air bubbles were observed during vacuum testing of the seam,
the test was considered to indicate a seam failure, and the repair and vacuum test repeated.
Specifically, the regulated pressure to the vacuum box was maintained at 15 psig during the test
process and vacuum pressure within the box was recorded in inches of mercury. Test results are
provided with the Liner Repair Daily Reports in Appendix 4.

Liner Repair Daily Reports have been provided in Appendix 4. Photo documentation is provided in
Appendix 5.
10. REPAIR TEST RESULTS/ QUALITY ASSURANCE/QUALITY CONTROL
,Results from vacuum testing of patch seams was recorded on the Liner repair Daily Reports.
As discussed above, the quality control standard applied to testing assumed that any single
appearance of a bubble in any part of a tested patch would be considered to be a failure of the patch,
requiring replacement and reattachment of the entire patch.
Following the testing, each day's test results were listed by date and test number on the last Liner
Repair Daily Report of the period in which the repairs and tests for that segment were completed.
Vacuum tests results are provided in Appendix A.
11. CONCLUSIONS
During the period from June 2010 to June 4, 2012, CellI liner repair activities were observed by
Utah Registered Professional Engineer Harold R. Roberts, and Mill Facility Engineer Steve Snyder.
EFR believes that the Cell 1 liner repairs have been performed consistent with:
• the Liner Maintenance Provisions,
• EFR's Plan and Schedule submitted on August 18 and revised on August 30, 2010, and
• the July 31,2012 timeframe identified in DRC's September 24,2010 Conditional
Approval and Confirmatory Action letter to EFR.

Re: State of Utah Ground Water Discharge Permit No. UGW370004 White Mesa
Uranium Mill-Notice Pursuant to Part I.G.3 of the Permit, Utah Radioactive Materials
License No. UT1900479, and Utah Administrative Code ("UAC") R317-6-6.16(C)(1)
Please take notice pursuant to.-the Part -1.0.3 of-the White Mesa MH1.'s ~the "Mill's") State of
Utah Groundwater Discharge Permit No. UGW370004 (the "Permit"), Utah Radioactive
Materials License No. UT1900479 (the "License"), and Utah Administrative Code (HUAC")
R317-6-6.l6(C)(1) that Denison Mines (USA) Corp., as operator of the Mill and holder of the
Permit and License, failed to meet the standards in Condition 11.3 of the License, by
accumulation of "sufficient fluid in the leak detection system" ("LDS") of Cell 1, as described in
more detail below.
The accumulation of fluid in the LDS was discovered at 2:50 PM on Wednesday, June 2,2010.
Sufficient fluid had accumulated by 8 :25am Thursday, June 3 to permit collection of samples
and initial pH testing to ascertain whether the fluid originated from the disposal cell. The initial
pH testing in at 8:45am on June 3 indicated that the liquid originated from the disposal cell.
Initial notice of this accumulation of liquid in the LOS was given by telephone to the Utah
Departtnent of Environmental Quality Executive Secretary at 2:48pm on Thursday June 3, 2010
(within 24 hours of the discovery and within 7 hours of determination of the origin of the fluid).
1. Facts and Background Information
a) Condition 11.3 of the Mill's State of Utah Radioactive Materials License No.
UT1900479 (the "License") requires that licensee implement a leak detection
monitoring system for each of the tailings cells. According to condition 11.3:
(i) The licensee shall measure and record the ·'depth to fluid" in each of the tailings
disposal cell standpipes on a weekly basis. If sufficient fluid is present in the leak
detection system (LDS) of any cell, the licensee shall pump fluid from the LDS,
to the extent reasonably possible, and record the volume of fluid recovered. Any
fluid pumped from an LDS shall be returned to a disposal cell.
(ii) If fluid is pumped form an LDS, the licensee shall calculate the flow rate by
dividing the recorded volume of fluid recovered by the, elapsed time since fluid
was last pumped or increases in the LDS fluid levels were recorded, whichever is
the more recent. The licensee shall document the results of this calculation.
(iii) Upon the initial pumping of fluid from an LDS, the licensee shall collect a fluid
sample and analyze the fluid for pH and the parameters listed in paragraph A of
this license conditions. The licensee shall determine' whether the LDS fluid
originated form the constituents listed in paragraph A of this license condition or
has a pH level less than 5.0. If either elevated constituent levels or a pH less than
5.0 is observed, the licensee shall assume that the disposal cell is the origin of the
fluid.
The above requirements have been incorporated into the Discharge Minimization
Technology Plan in Section 3.1 of the Mill's Environmental Protection Manual.
b) Condition 11.3 further requires the ongoing weekly Ineasurement of depth to fluid if the
calculated leakage flow rate is less than 1 gpm, and additional notification and
mitigation requirements if the leakage rate is greater than 1 gpm.
c) The Liner Maintenance Provisions appendix of the Mill's DMT Plan describe the types
of repairs that will be implemented following identification of a leakage source, as well
as requirements for a repair report describing the nature of the damage and the repairs.
d) Section 1.G.3 of the Mill's groundwater Discharge Permit (the "Permit") requires thatin
the event that the Permittee fails to maintain DMT or BAT or otherwise fails to meet
DMT or BAT standards as required by the Permit, the Permittee shall submit to the
Executive Secretary a notification and description of the failure according to R317 -6-
6. 16(C)(l ). Notification shall be given orally within 24-hours of the Permittee's
discovery of the failure of DMT or BAT, and shall be followed up by written
notification, including the information necessary to make a determination under R317-

6-6.16(C)(2), within five calendar days of the Permittee's discovery of the failure of
best available technology.
e) During the routine tailings inspection performed at approximately 2:50pm on June 2,
2010, the Cell 1 LOS standpipe was observed to have accumulated approximately 7
feet 6 inches of liquid compared to the previous day. The preceding day's recorded
observation indicated that the LOS standpipe was "dry" (a measured level of 63 feet 4
inches).

g) The result recorded from an initial pH paper check on a sample of LDS standpipe fluid
was a pH of approximately 2.0 to 3.0.
2. Actions Taken
Upon receipt of the initial inspection result, the Mill's Environmental Coordinator notified the
Mill Manager at 3:00pm that day. The following plan of action was immediately put into place
in accordance with the Liner Maintenance Provisions and Section 3.1 of the Mill's
Environmental Protection Manual:
a) In accordance with License condition 11.3, pumping of the LDS to dryness, and
monitoring of level change with time to estimate leakage rate, began at 8:25am on June
3;
b) In accordance with License condition 11.3, the calculated leakage rates estimated since
the initial identification of the leakage have not exceeded 1 gpm
c) In accordance with License condition 11.3, an initial pH paper test to detelmine the
origin of the liquids was performed at 8:45am on June3. The pH paper indicated an
approximate pH of 2.0 to 3.0. Based on this result, it was determined at 8:45am that
the LDS liquids' originated from the Cell 1 liquids;
d) In accordance with License condition 11.3, upon the initial pumping of the LDS,
samples and duplicates were collected and shipped to Energy Laboratories and
America West Laboratories on June 3 for analysis for the full suite of groundwater
point of compliance analytes and parameters;
e) Consistent with Section 1.G.3 of the Permit, verbal notification was given to the
Executive Secretary at 4:48pm on June 3, 2010, within 24 hours of discovery of the
liquid level and within 9 hours of initial determination that the liquids Oliginated from
the cell solutions. The verbal notification was followed by this written notification
within five days of discovery;
f) Solutions continue to be pumped from Cell 1 to Cell 4A at the time of this notice.
3. Actions That Will be Taken to Prevent a Reoccurrence of this Incident
The following actions will be taken to prevent a reoccurrence of this incident:
a) The Mill will continue to monitor the rate of leakage into the LDS;
4
OENISOn
MINES
b) The Mill will continue efforts to identify the location of any tear(s) or other source(s)
of leakage;
c) Once the Mill has identified the location of the tear( s) or source( s) of leakage, any leak,
hole or other damage will be repaired by installation of a PVC repair patch, in
accordance with the Liner Maintenance provisions appendix of the Mill's DMT Plan;
d) A repair report containing a root cause analysis and further recommendations will be
submitted to the Executive Secretary within 30 days of the initial telephone
notification.
4. Required Reporting

Re: State of Utah Ground Water Discharge Permit ("GWDP") No. UGW370004 White Mesa Uranium Mill -
Plan and Schedule for Cell 1 Inspection and Repairs
Dear Mr. Lundberg:
Reference is made to Denison Mines (USA) Corp's ("Denison's") notice letter of June 7, 2010 and telephone
conference with Utah Department of Environmental Quality ("UDEQ") personnel on August 12, 2010. Denison's
June 7, 2010 letter provided a notice to the Executive Secretary regarding the discovery of fluid in the Leak
Detection System ("LDS") of the White Mesa Mill's (the "Mill's") Cell 1. This letter responds to Denison's
commitment in the June 7, 2010 letter and the August 12, 2010 phone call in which Denison agreed to provide
UDEQ a written plan and schedule for:
• determ ination of the root cause,
• identification of the extent of damage, and
• execution and reporting of repairs to the Cell 1 liner system.
Background and Design of Cell 1
Tailings Cell 1 serves as the Mill's primary liquid evaporation basin. Cell 1 consists of the following major
design elements:
1) Cross-valley Dike and East Dike -constructed on the south side of the pond of native granular materials
with a 3:1 slope, a 20-foot crest width, and a crest elevation of about 5,620 ft above mean sea level (amsl).
A dike of similar design was constructed on the east margin of the pond, which forms a continuous earthen
structure with the south dike. The remaining interior slopes are cut-slopes at 3:1 grade.
2) Liner System -including a single 30 mil PVC flexible membrane liner (FML) constructed of solvent welded
seams on a prepared sub-base. The top elevation of the FML liner was 5,618.5 ft amsl on both the south
dike and the north cut-slope. A protective soil cover layer was constructed immediately over the FML with a
thickness of 12-inches on the cell floor and 18-inches on the interior sideslope.
Letter to Rusty Lundberg on Cell 1 Repair Plan
August18,2010
Page 3
Section 1.G.3 of the GWDP requires that in the event that the Permittee fails to maintain DMT or BAT or
otherwise fails to meet DMT or BAT standards as required by the Permit, the Permittee shall submit to the
Executive Secretary a notification and description of the failure according to R317 -6-6.16(C)(1). Notification
shall be given orally within 24-hours of the Permittee's discovery of the failure of DMT or BAT, and shall be
followed up by written notification, including the information necessary to make a determination under R317-6-
6.16(C)(2), within five calendar days of the Permittee's discovery of the failure of best available technology.
UDEQ has not considered the Cell 1 liner system to meet BAT requirements and has excluded it from BAT and
DMT requirements in the Mill's GWDP. Hence, DMT reporting requirements do not specifically apply to the Cell
1 LDS. However, Denison chose to notify the Executive Secretary within 24 hours of the initial onset, by
telephone call on June 3, 2010, because the fluids in the Cell 1 LDS were assumed to represent a potential liner
defect that requires notice under Part I.E.7(f) of the GWDP. The Executive Secretary received written
notification within 5 days of the initial incident on June 7, 2010. Denison also provided a follow-up verbal
notification within 24 hours of the recurrence by phone call on August 8, 2010.
Initial Identification of Need for Repairs and Response Actions to Date
During the routine tailings inspection performed at approximately 2:50pm on June 2, 2010, the Cell 1 LOS
standpipe was observed to have accumulated approximately 7 feet 6 inche$ of liquid compared to the previous
day. The preceding day's recorded observation indicated that the LOS standpipe was "dry" (a measured level
of 63 feet 4 inches). Sufficient fluid had accumulated by 8:25am Thursday, June 3 to permit collection of
samples and initial pH testing to ascertain whether the fluid originated from the cell. The initial pH testing in at
8:45am on June 3, showed a pH of 2 to 3, indicating that the liquid originated from the cell. Initial notice of this
accumulation of liquid in the LOS was given by telephone to the Utah Department of Environmental Quality
Executive Secretary at 2:48pm on Thursday June 3, 2010 (within 24 hours of the discovery and within 7 hours
of determination of the origin of the fluid).
Upon receipt of the initial inspection result, the Mill's Environmental Coordinator notified the Mill Manager at
3:00pm that day. The Mill took the following steps, in accordance with License condition 11.3, the Mill's Liner
Maintenance Provisions, and Section 3.1 of the Mill's Environmental Protection Manual.
The Mill collected samples and duplicates on June 3 for analysis at Energy Laboratories and America West
Analytical Laboratories for the full suite of groundwater point of compliance analytes and parameters.
Characterization results confirmed that the source of the fluids in the LOS is tailings solutions.
Following the sampling on June 3, the Mill pumped the LDS to dryness, and began monitoring the level change
with time to estimate solution accumulation rate. The calculated rates estimated from this process indicated
that the solution accumulation rate did not exceed 1 gpm, and ranged from approximately 0.05 to 0.5 gpm.
At the time the LDS level was noted on June 3, the Cell 1 solution level was approximately 5614.57 feet amsl.
The Mill lowered the Cell 1 solution level during the month of June in order to reduce or eliminate the flow into
the LDS, and to allow inspection and repair of damage to the Cell 1 FML. The Cell 1 level was dropped to a low
of 5613.40 feet amsl during this period. Maintenance identified some FML damage and performed repairs
during the period when the level was lowest. Following the repairs, the Cell 1 liquid level was allowed to
gradually return to its June 3 level, and the LDS remained dry until a recurrence of the LDS liquid level was
identified on August 7.
The Mill experienced periodic heavy rains in late July and early August. During the August 7, 2010 tailings
inspection, the Cell liquid level had reached 5614.22 feet amsl. At that time, the Environmental Technician
OENISOJ)JJ
MINES
3
Letter to Rusty Lundberg on Cell 1 Repair Plan
August18,2010
Page 4
identified that the LOS had an observable liquid level. Liquid samples and duplicates were once again collected
and shipped for analysis, and pumping and estimation of the LOS fill rate was resumed.
At this time, Mill management took a more aggressive approach to lowering the Cell 1 solution level. Cell 1 was
pumped at maximum transfer pump rate into Cell 4A, beginning approximately August 8. At the time of this
writing, Cell 1 's solution level has been reduced to 5613.91 feet amsl and the Mill continues to pump and
monitor the recovery level in the LOS.
The Mill also continues to estimate the flow rate into the LOS between pumping. Since the August 8 detection,
the flow rate into the LOS has not exceeded 1 gpm, and has ranged from 0.01 to 0.02 gpm, or approximately
one tenth to one twentieth of the rate during the June detection.
During phone discussions with UDEQ personnel on August 12, 2010, UDEQ agreed with Denison that both the
June and August identifications of LOS solutions were all part of one event. At this time, Denison has
concluded that:
• The inspection and repairs performed on the Cell1 FML in June and July were apparently not
successful in identifying all of the damage which required repair.
• The temporary cessation of flow into the LOS between the June and August Cell 1 LOS fluid detections
may have resulted from the lowering of the solution level to a point below the remaining tears or
damage to the FML. However, as the solution level in Cell 1 rose, it reached the elevation of one or
more remaining defects in the liner. Additional systematic inspection and repair of the FML will
therefore be required.
Plan
Denison proposes the following plan of action to:
• Identify and confirm the root cause of the observed solutions in the Cell 1 LOS.
• Locate the specific areas of the FML requiring repair.
• Conduct a systematic and orderly repair process that does not generate further damage to the FML
• Confirm that the repairs have reduced or eliminated the flow into the LOS
• Document the findings, root cause, and response actions.
This plan provides a phased approach to identification and repair of the defects in the Cell 1 liner. It is based on
the need for a stepwise schedule to systematically uncover and inspect all potentially damaged areas,
beginning with those areas with the highest potential for wear and resulting damage, and to perform the repairs
without incurring further damage to the FML during the removal of the protective soil cover. Denison does not
want to disturb any more of the soil cover, and expose more of the FML to the environment, than is necessary
in order to minimize the risk of further damage to the FML. In addition, the location of the repairs near the
tailings solution will require special safety precautions which add to the time required for repairs. Further, the
ability to perform any repairs during the winter months will be limited due to snow coverage and slippery
conditions. The key steps in the inspection and repair process will be as follows.

Phase I Plan and Schedule
1. Reduce the Cell 1 solution level approximately to the level it reached during the June repairs. Solutions
from Cell 1 are currently being pumped from Cell 1 to either Cell 3 or Cell 4A. The solution level should
be down to the June elevation by approximately August 31 st.
2. Identify areas in Cell 1 with highest potential for damage (where pipes enter and exit the cell, etc.). The
most obvious sections are in the southeast corner of Cell 1 and in the south central area of Cell 1 where
the pump barge is located. These areas are estimated to be approximately 200 feet of the Cell 1 bank.
3. Systematically inspect and repair the FML areas with the highest likelihood of damage first. The 200
feet of the highest risk areas will be uncovered and repaired as necessary. It is estimated that these
repairs will take approximately 10 weeks, until October 31, 2010.
4. Allow the level in the cell to recover and confirm that solutions do not reappear in the LOS. Solution
from the Mill process or from Cell 3 or Cell 4A will be pumped into the cell and the LOS sump will be
monitored. It is estimated that this step will take approximately 4 weeks, until November 30, 2010.
Phase II Plan and Schedule
5. If, after the process in steps 1 through 4 has been completed, solutions reappear in the LOS , the
solution level in Cell 1 will again be reduced in order to achieve dryness in the LOS. It is expected that
it will take some time for the Cell 1 pond solution to be reduced to the level necessary to achieve
dryness in the LOS, and for the LOS to be verified to be dry. However, this procedure is expected to be
accomplished by December 31,2010.
6. After the solution level in Cell 1 is lowered, the next highest area of concern (likeliest area for damage)
will be uncovered, inspected, and repaired. Following the repairs, the Cell 1 solution level will be
allowed to gradually recover. The schedule for completion of this step will depend on winter conditions
and will be developed with the concurrence of the Executive Secretary.
7. If, after the process in steps 5 and 6 has been completed, solutions reappear in the LOS, the solution
level in Cell 1 will again be reduced in order to achieve dryness in the LOS. The cycle of steps 1 and 2
will be repeated, as necessary, until all the necessary repairs have been made to achieve dryness in
the LOS. The schedule of subsequent cycles of steps 5 and 6 will be developed with the concurrence
of the Executive Secretary.
Reporting
The Liner Maintenance Provisions appendix of the Mill's OMT Plan describes the types of repairs that will be
implemented following identification of solutions in the LOS, as well as requirements for a repair report
describing the nature of the damage and the repairs. As required by the Liner Maintenance Provisions, a repair
report will be submitted to the Executive Secretary following completion of repairs to the Cell 1 liner. The repair
report will contain, in addition to a root cause analysis, the following elements:
• Repair narrative describing the nature of the damage and the repair work completed to repair the
damage.
• Repair material type used to complete the repair

Re: State of Utah Ground Water Discharge Permit ("GWDP") No. UGW370004 White Mesa Uranium
Mill -Plan and Schedule for Cell 1 Inspection and Repairs, Update
Reference is made to Denison Mines (USA) Corp's ("Denison's") notice letter of June 7, 2010 and telephone
conferences with Utah Department of Environmental Quality ("UDEQ") on August 12, and August 23, 2010.
Denison's June 7, 2010 letter provided a notice to the Executive secretary regarding liner repair work needed to
address the discovery of fluid level in the Leak Detection System ("LOS") of the White Mesa Mill's (the "Mill's")
Cell 1. In response to a phone conference on August 12, 2010, Denison provided a status update letter to
UDEQ on August 18, 2010 containing a proposed plan and schedule for inspection and repairs to Cell 1.
UDEQ and Denison reviewed the proposed plan during a conference call on August 23, 2010. This letter
responds to UDEQ's request during the August 23 conference call that Denison provide a written submittal that:
• includes an update of the estimated fluid inflow rate during the August LDS monitoring, and
• modifies and clarifies the repair schedule.
Current Status
Since the time of the August 7 detection of fluid in the LOS, the Mill has continued to:
• circulate and transfer fluids to reduce the solution level in Cell 1,
• pump and monitor the observable LOS liquid level, and
• estimate the rate of inflow of fluids into the Cell 1 LOS from the pumped LOS fluid volumes.
Preliminary analytical data received to date has confirmed Denison's assumption that the observed fluid in the
LOS consists of Cell 1 solutions.
The Cell 1 LOS system was determined to be dry, that is, no fluid was observable in the standpipe, on August
18, 2010 and remains dry at the time of this writing. Denison has concluded that at the current liquid pool level
of 5613 feet amsl, the liqUid level is lower than any tears or damaged areas in the liner that produced the
observable LOS liquid level in August 7, 2010.
'.
Letter to Rusty Lundberg on Cell 1 Repair Schedule
August 30, 2010
Page 2
As requested by UOEQ, Denison has provided in Table 1, below, estimates of inflow of solution into the Cell 1
LOS from the time of the LOS liquid detection on August 7, 2010 until the LOS system became dry on August
18, 2010, stated in gallons per minute ("gpm").
Update to Repair Schedule
Cell 1 has a perimeter above the 5613 foot amsl level of approximately 6,500 linear feet, of which approximately
6,000 feet have not been recently inspected and/or repaired. A full inspection and repair of all areas of the liner
surface above the 5613 foot level would require the systematic removal of the protective soil cover, inspection
of the exposed, uncovered flexible membrane liner ("FML") material, and repair of any identified damaged areas
at or above this level. Denison has explained in our plan letter of August 18, 2010 and phone conversation of
August 23, 2010, that Denison does not wish to expose significant areas of the FML at anyone time or to
disturb any more of the FML than is necessary, but plans to inspect and repair the FML in sections in a
stepwise fashion to minimize the risk of creating any new damage. Further, Denison plans to uncover and
inspect first the areas of the FML that are most likely to exhibit tears or damage, such as areas near or affected
by discharge piping vibration or other stress factors. Denison plans to raise the solution level in Cell 1 above
5613 fmsl periodically in order to test the success of certain steps in the repair process.
Denison has provided, in Table 2, below, an updated estimate of the time required to perform repairs to the Cell
1 liner as described in the August 18, 2010 update letter and discussed in the August 23 phone conference with
UDEQ.
Denison has already mobilized, from among available personnel, one four-man crew including one supervisor,
and has repaired 200 linear feet of liner surface since June 2010.
Denison will need to expand the liner maintenance force to three (3) three-man crews. Although this process is
underway, development of a full complement of repair personnel will require a minimum of several weeks due to
the time needed to identify, recruit, and train qualified personnel. Denison does not plan to expand the repair
team to include larger crews because the maintenance of safe working conditions is of paramount priority.
Specifically, the ability of supervisors to enforce adherence to safety requirements is most effective at smaller
crew sizes. Denison does not plan to expand the number of repair crews (that is, total repair personnel beyond
three crews) due to practical aspects of personnel retention. It is Denison's intention to be able to utilize each
cprew member for other operational tasks throughout the Mill during periods when weather conditions preclude
liner repair work. Having sufficient alternate work activity for crew members during down periods is critical for
minimizing attrition and maintaining a sufficient number of qualified, trained personnel on hand during repair
periods.
Three (3), three-man crews can theoretically uncover, inspect, and repair the FML at a peak rate of
approximately 160 linear feet per week, or 640 linear feet per month, under optimum conditions. The theoretical
peak productivity is tabulated in the column in Table 2 labeled "Maximum Feet Repaired under Optimum
Conditions." The theoretical peak productivity would require:
• a full complement of trained staff available every day of the month with no attrition,
• safe access conditions suitable for liner repair every day of the month (no snow cover, no muddy or
slippery footing), and
• weather conditions suitable for liner repair work every day of the month (above 50°F, no high winds,
no snow or rain).

MINES
Letter to Rusty Lundberg on Cell 1 Repair Schedule
August 30, 2010
Page 3
Several factors need to be considered to adjust the theoretical peak productivity to real productivity for the
purposes of this schedule.
Pre-training. Denison requires all repair crew members to be appropriately trained in the technical and health
and safety aspects of the liner repair task before being assigned to a crew.
Safe and effective access. Denison will not require crews to access the FML under slippery, muddy
conditions, high winds, or other weather conditions that create hazardous footing. The FML soil cover cannot
be effectively removed or the FML inspected under snow cover.
Other weather factors. The ability to manipulate and repair damaged sections of the FML and the effectiveness
of the repair sealants depend on moderate temperatures, generally above 50°F.
Denison has incorporated key assumptions to address the factors above and adjust the theoretical peak
productivity to a more realistic monthly productivity in Table 2. The realistic monthly and total productivity is
listed in the column labeled "Actual Feet Repaired Based on Assumed Conditions." The value in the "Actual
Feet Repaired" column is based on the following assumptions:
1. S~ffjcient numbers of trained personnel are not in place at th~ time of this writing. Recruiting and
training to reach a full complement of three (3) three-man crews is underway. Hence, the maximum
feet repaired will increase from the first to second month (September to October) of the repair schedule
as the full complement of repair personnel are recruited or transferred and trained. However, the
indicated linear footage to be repaired by the end of September 2010 is higher than the 200 linear feet
proposed in our plan letter of August 23,2010.
2. No repairs will be performed during the months of November through March of each working year due
to snow or muddy conditions, temperatures too low for proper setting of repair materials, or both.
3, The percentage of working days available in the remaining months (April through October) in Table 2
have been adjusted based on typical weather conditions anticipated in each of those months.
As mentioned above the projected linear feet per month, and total months to address the entire perimeter of
Cell 1 are based on these specific assumptions. If weather conditions vary from the assumed conditions,
productivity may be higher or lower than tabulated, which would affect the schedule set out .in Table 2. Also, if
repairs are determined to be successful at any point in time, based on no inflow of fluids into the Cell 1 LOS
after raising the solution level in Cell 1 , then Denison may discontinue any further repair work at that time.
Please contact the undersigned if you have any questions or require any further information.

Denver, Colorado, 80265
Subject: August 30,2010 Denison Mines (USA) [DUSA] White Mesa Uranium Mill -Plan and
Schedule for Cell 1 Inspection and Repairs, Update -Conditional Approval and
Confirmatory Action Letter
Dear Mr. Frydenlund:
On June 3, 2010 DUSA notified the Utah Division of Radiation Control (DRC) by telephone that
on June 2, 2010 an accumulation of fluid was discovered within the Tailings Cell 1 leak detection
systern (LOS). An initial pH paper test showed that the fluid in the LDS indicated a pH of 2.0 to
3.0; therefore, the fluid found in the LOS originated frOln Cell 1. Written notification of the
Tailings Cell 1 leak was made in a June 7, 2010 DUSA letter. In the letter, DUSA states" ... a
repair report will be submitted to the Executive Secretary with 30 days of the initial telephone
notification ... " This repair report was not sublnitted by July 5,2010 as committed to by OUSA.
To repair the liner, DUSA lowered the solution level in Cell 1 to 5613.10 feet amsl. This
appeared to eliminate the tl ow of wastewater to the LDS. OUSA maintenance identified some
FML damage and perfonned repairs during the period when the water level was lowest.
Following the repairs, the Cell 1 liquid level was allowed to return to the June 3, 2010 level. The
Cell 1 LDS remained dry until fluid was observed again in the LOS on August 7,2010. The DRC
was Inade aware of the August 7,2010 Cell 1 leak in an August 8, 2010 telephone call. During an
August 12, 2010, telephone call, the DRC agreed with DUSA that both the June and August 2010
identi'fications of fluid in the Cell 1 LOS were part of one event. Apparently, the repairs made to
the Cell 1 liner prior to August 7, 2010 were not successful in identifying all the dan1age which
required repair.
During the August 12, 2010 phone call, DUSA agreed to provide the DRC with a written plan and
schedule for: 1) determination of the root cause, 2) identification of the extent of damage, and

3) execution and reporting of repairs to the Cell 1 liner systenl.
In an August 18, 2010 DUSA letter, DUSA provided a plan and schedule for Cell 1 Inspection
and Repair. DUSA's proposed plan and schedule was to be conducted in phases, as summarized
below:
Phase 1
1. Reduce the solution level contained in Cell 1 down to the same level it reached during the
June 2010 repairs. This was to be accomplished by approximately August 31, 2010.
2. Identify areas in Cell 1 with the highest potential of damage. These areas are estimated to
be approximately 200 feet of the Cell 1 inside slope.
3. Systematically inspect and repair the FML areas with the highest likelihood of damage
first. This should be accomplished by approximately October 31, 2010.
4. Allow the solution level within Cell 1 to recover to the pre-June 2010 levels and confinn
that solutions do not reappear in the LDS. It is estimated that this step will take
approximately 4 weeks, or until November 30,2010.
Phase II
5. If after steps 1 -4 have been completed and solutions reappear in the LDS, the solution
level in Cell 1 will again be lowered to about 5613 feet ams!. This should be
accomplished by approximately December 31 , 2010.
6. After the solutions level in Cell 1 is lowered, the next highest area of concern on the inside
slope will be uncovered and repaired. Following the repair, the Cell 1 solution level will
be allowed to recover to pre-June 2010 levels.
7. If after steps 5 & 6 have been completed and if solutions reappear in the LDS, the solution
level contained in Cell 1 will again be lowered to 5613 feet amsl. The cycle steps will be
repeated as Inany times as necessary, until DUSA is able to achieve dryness in the Cell 1
LDS.
After review of the August 18, 2010 Cell 1 repair plan and schedule, the DRC identified three
concerns, as follows:
• The proposed repair plan schedule was open ended and there was no specific date where
DUSA committed it would have the Cell 1 leak fully repaired and the LDS dry.
• The phased approach as proposed Inay take several years before the Cell 1 leak repaired.
This is not appropriate, nor is it tilnely. DUSA needed to set a date when the entire liner
will be checked and repaired above 5,613 feet amsl.
• The August 18, 2010 repair plan failed to include a table for the estimated Cell 1 leakage
rate for the leak identified on August 7, 2010.
On August 23,2010 the DRC shared these concerns with DUSA in a conference call. In the
Ineeting, DUSA agreed to submit a revised repair plan by August 30, 2010. This repair plan
would include a CellI leakage rate fOl:, the leak identified on August 7, 2010 and a date when the
entire Cell 1 liner will be checked and repaired fully and completely across all inside slope areas
above 5,613 feet amsl, if necessary.
Page 3
Conditional Approval
DUSA provided a revised Cell 1 Repair Plan in a letter dated August 30, 2010. In the letter,
DUSA committed that the entire Cell 1 liner area above 5,613 feet amsl would be repaired by July
31, 2012. This schedule is hereby conditionally approved, contingent on compliance with the
additional confirmatory actions discussed below.
In the August 30, 2010 letter, DUSA also provided a Table 1 that included the estimated leakage
rate at Cell 1 for the leak identified on August 7, 2010. After reviewing the information contained
in Table 1, the DRC identified several discrepancies. The table showed the standpipe was
considered dry at different depths (i.e. 60 feet 2 inches, 63 feet 9 inches, 65 feet, and 66 feet 4
inches) for the August 7,2010 leak, while the standpipe was considered dry at 63 feet 4 inches for
the June 2, 2010 leak.
On September 13, 201 ° the DRC notified Ms. Jo Ann Tischler of DUSA of these discrepancies.
Ms. Tischler said she would find out the cause of these problems and sublnit an updated table with
an explanation for these discrepancies. Ms. Tischler provided an updated table bye-mail on
September 14, 2010 and explained that the discrepancies were caused by a 6 foot extension added
to the standpipe on August 10, 2010, as requested by the ORC. However, the 6 foot extension
added to the standpipe doesn't explain why the depth considered dry was inconsistent fTom one
Ineasurelnent to another (i.e. 63 feet 9 inches, 65 feet, and 66 feet 4 inches) after August 10, 2010.
A conference call was held with DUSA on September 15,2010 to discuss this issue. During the
meeting, the DRC voiced a concern that perhaps debris had fallen down into the standpipe and
could be preventing DUSA from obtaining true reading within the Cell 1 LDS .
Confirmatory Action
During the September 15, 2010 conference call, DUSA cOlnmitted to resolve these issues by
doing the following:
1. Determine the root cause of the apparent discrepancies of the Estimation of Cell 1 Leakage
Rate, (Table 1) and SUbluit written findings by September 30, 2010 for Executive
Secretary review and approval.
2. Perform a video log of the Cell 1 LDS standpipe down to the T -joint with the slotted
collection pipe and detennine the total downslope distance to the nearest 0.1 foot. If any
debris is observed within the standpipe, this debris will be ren10ved. If debris is observed,
another video log will need to be performed after the debris is reluoved to document that
the standpipe is free of deblis. Both video logs will be performed and submitted for DRC
review and approval by November 1, 2010
3. If after review of both the above DUSA submittals, the DRC determines that additional
cOlTective action is required, DUSA will meet with the DRC to discuss and negotiate a
plan of action and schedule to resolve the Cell 1 LDS problems identified.
4 . The Cell 1 liner will be checked and repaired fully and completely across all inside
sideslope areas above 5,613 feet amsl on or before July 31,2012.
Page 4
5. Prepare and submit a Cell 1 Repair Report for Executive Secretary review and approval.
This Repair Report shall be included with the next quarterly DMT Report, as required by
Part I.F.2 of the Permit.
Please respond in writing within seven calendar days of receipt of this letter if you disagree with
the above agreed upon resolution or compliance schedule.
Thank you for your continued cooperation.

Re: State of Utah Ground Water Discharge Permit ("GWDP") No. UGW370004 White Mesa Uranium
Mill-Update on Findings on Cell 1 Leak Detection system (ULDS")
This letter report responds to the Utah Division of Radiation Control's September 22,2010 Conditional Approval
and Confirmatory Action Letter regarding the White Mesa Mill (the "Mill") Cell 1 leak detection system ("LOS")
and Denison Mines (USA) Corp's ("Denison's") telephone conversations with DRC on August 23, September
15, and September 21, 2010.
Description of the LOS Standpipe and Blow Pipe System.
The Cell 1 design and LOS has been described in the GWDP and the June 1979 D'Appolonia Engineering
Report Appendix A drawings. The above-ground monitoring portion of the LOS consists of a 14-inch covered
Drisco pipe (the "standpipe") containing a movable calibrated interior %-inch PVC tube (the "blow tube"). The
standpipe lies along the sideslope of the Celli dike beneath the flexible liner, and exits through an opening in
the flexible liner at the top of the south dike. The blow tube can be moved (slid) up or down within the standpipe
cover opening. Prior to August 2010, the top of the standpipe was nearly flush with the ground (dike) surface.
At that time, the length to the bottom of the standpipe and blow tube was 63 feet 4 inches (63.33 feet) along the
slope of the dike.
liquid level measurements are performed by use of the calibrated blow tube within the standpipe. To perform a
liquid depth measurement, the environmental technician blows into the blow tube and listens for a bubbling
response indicating the bottom end of the tube is in contact with liquid. He withdraws the tube in increments
and repeats the blowing process until the response sound indicates that the tube is no longer in contact with
liquid. He then records the measurement from the graduated blow tube, which indicates the depth of empty
tube/pipe, that is, how far down the standpipe/blow tube column does the liquid level begin. The height of liquid
in the sloped column is calculated by subtracting the empty blow tube depth from the full length of the
standpipe. All measurements made within the standpipe and blow tube are measurements along the sloped
incline and do not represent vertical head, per se.
Letter to Rusty Lundberg -Cell 1 LOS Update Report
September 30, 2010
Page 2
The volume of liquid accumulated in the system (infiltration volume) is estimated by pumping the entfre column
to dryness, collecting the pumped fluid into a series of four calibrated 5-gallon buckets, and recording a
collected volume measurement. As indicated in the Discharge Minimization Technology ("0MT") Plan, the
measured volume is divided by the elapsed time since the standpipe was last pumped dry to determine the rate
of influent flow (infiltration rate or accumulation rate) into the LOS system.
As mentioned above, prior to the modifications discussed in the next section, the length of the LOS standpipe
was 63 feet 4 inches (63.33 feet).
History of Extensions to the Pipe System
Prior to the August 2010 LOS liquid detection, at the request of David Rupp and Dean Henderson of ORC, Mill
personnel added a 2-inch collar and cover to the end of the standpipe and drilled a close-fitted opening in the
standpipe cover. The blow tube was extended by the same amount and was fitted through the opening in the
cover. Following this modification, the blow tube could still be moved up or down for measurement, and no
change to the measurement process was required. At this point, the length of the standpipe and blow tube
reached 63 feet 6 inches (63.5 feet). This change was indicated in the revisions to Table 1 provided to ORC on
August 30, 2010.
On August 10, 2010 at the request of David Rupp and Dean Henderson of ORC, Mill personnel again extended
the exposed (and now covered) end of the LOS standpipe and blow pipe. The blow pipe and standpipe were
both extended to a new length of 69 feet 6 inches (69.5 feet). This change was indicated in the revisions to
Table 1 provided to ORC on August 30, 2010.
Investigation of the System and Measurement Process
As committed in the phone conversation of September 15, 2010 I visited the Mill and inspected the Cell 1 L.OS
measurement system equipment on Friday September 24, 2010 and observed a demonstration of the use of
the blow tube and measurement process. During that visit, I also reviewed with the environmental technician
the methods of collecting and recording LOS data, and the meaning of each of the field notes taken during the
measurement processes in June and August 2010. The environmental technician also provided supplementary
measurement data collected during the June 2010 period, when the Cell 1 level was lowered to keep the LOS
system dry and allow for repairs. During the period that the Cell 1 level was lowered, the Cell 1 LOS level was
monitored daily except on weekends. That data has been .included in Attachment 1 to this letter report.
I performed a quality check and standardization of the data previously reported to DRC and revised the data in
Table 1 for both events to use the same format and presentation. Any changes to reported data resulting from
the quality check are hjghlighted in bold and yellow in the standardized table in Attachment 1 to this report.
Findings and Reason for Confusion in ORC Interpretation of Table 1
The versions of Table 1 provided to ORe for the two different detection events were presented in two different
formats. The differences resulted from two different, but accurate, recording styles used by field personnel to
record and report the data to Denver Corporate personnel. The table attached to the August 18, 2010 letter
summarizing the June 2010 detection showed both the blow pipe and total pipe measurements in the same
column. In this table, the word "dry/' included from the field notes, indicated that the second depth was the "dry
depth reached at bottom of the pipe". The August 30, 2010 letter added a second table with the level data from
the August 7, 2010 detection. The second table was in a format that showed only the blow pipe measurements
with the word "dry" included from the field notes, which indicated that the tube was "pumped dry after this

measurement". In this table, the dry depth at the bottom of the pipe was not indicated, but was reached in
every pum ping event.
The revised tables provided to ORC on August 30 and September 14, 2010 did not explain this difference in
presentation of the field data. The updated tables in Attachment 1 to this letter report for the two occurrences
have been rectified so that both tables report the dry depth at the bottom of the tube each time dryness was
achieved. The attachments also clarify what "dry" indicated. The data has been reformatted so that all data for
both detection events is presented on the same basis.
One minor subtraction error by the Mill personnel affected one liquid level value on August 7, 2010. The liquid
height reported as 1.70 feet has been corrected to 1.83 feet in the updated attachment to this letter report as a
result of the recalculation.
One minor error resulted from conversion of data for presentation in the Table 1 attachments. The error
affected only one influent rate to the second decimal point on August 11, 2010. The rate of 0.01 gpm has been
corrected to 0.02 gpm in the attachment to this letter report as a result of the recalculation. The corrected
influent rates remain well below the leakage rate of 1 gpm as required by the Mill's License Condition 11.3. The
errors had no effect on confirming that the LOS was pumped dry after each pumping effort, or on determination
of when influent into the LOS ceased.
In every case of pumping, the pipe was pumped dry to the bottom of the LOS pipe. During the August
detection, prior to August 10, 2010, this bottom depth was consistently 63 feet 6 inches (63.5 feet). After
August 10, this bottom depth was consistently 69 feet 6 inches (69.5 feet).
On August 18, 2010 , one inch of solution was measured at the bottom of the LOS . One inch is not a sufficient
fluid level to allow priming and operation of the downhole pump; hence the inch of solution was not pumped.
The inch of solution had evaporated to dryness (69.5 feet) by the time of the next day's monitoring on August
19, 2010 and has remained dry since that date.
The environmental technician performing the measurements is consistently able to reach the same depth at the
bottom of the standpipe with the blow tube. That is, there is no apparent object or deposition creating any
obstruction in measurement. Sedimentation, if any eXists, may lie along the side of the sloped standpipe or the
bottom, but does not interfere with the ability to take measurements of liquid to the same depth in the standpipe
each time.
Conclusions
1. Based on my review of the LOS measurement process and reported data, there were no apparent
errors in liquid level measurement.
2. Based on my review of the LOS measurement process and reported data, there were no apparent
errors in liquid volume measurement or time measurement -the two factors entering into the estimation
of LOS infiltration rate.
3. One minor subtraction error by the Mill personnel affected one liquid height value on August 7, 2010.
The error did not affect estimation of pumped volume or ability to monitor when influent into the LOS
ceased.

4. One minor error resulted from Denver Corporate conversion of data for presentation in the Table 1
attachments. The error affected only one reported influent rate to the second decimal point on August
11, 2010. The rate of 0.01 gpm has been corrected to 0.02 gpm in the attachment to this letter report
as a result of the recalculation. The corrected influent rate remains well below the leakage rate of 1
gpm as required by the Mill's License Condition 11.3. The errors had no effect on confirming that the
LOS was pumped dry after each pumping effort, or on determination of when influent into the LOS
ceased.
5. Based on the ability to read a liquid level to the bottom of the liquid standpipe, there does not appear to
be any obstruction or significant deposition in the bottom of the standpipe sufficient to affect monitoring,
In any event. the actual depth to the bottom of the standpipe is not significant as long as it is a constant
point of reference for liquid depth, as it appears to be.
6. The measurement system approved in the license is being appropriately implemented.
7, The variations noted by ORC were due to the difference in presentation of data in the two notices to
ORe. Data reporting has been standardized, and the attached revisions to Table 1 from both the June
and August 2010 detection notices have been modified in format and presentation to address the
sources of confusion.

Re: State of Utah Ground Water Discharge Permit ("GWDP") No. UGW370004 White Mesa Uranium
MiII-Update on Findings on Cell 1 Leak Detection system ("LOS")
This letter report responds, in part, to the Utah Division of Radiation Control's September 22, 2010 Conditional
Approval and Confirmatory Action Letter regarding the White Mesa Mill (the "Mill") Cell 1 leak detection system
("LOS") and Denison Mines (USA) Corp's C'Denison's") telephone conversations with DRC on August 23,
September 15, and September 21, 2010. A separate letter which summarized Denison's inspection of the LDS
level measurement process and resolved apparent inconsistencies in Cell 1 LOS depth and liquid level
measurements, as requested in ORC's September 22, 2010 letter, was submitted to DRC on September 30,
2010.
Status of Required Actions in ORe's September 22, 2010 Letter
Item 1. Determine the root cause of the apparent discrepancies of the Estimation of Cell 1 Leakage
Rate. (Table 1) and submit written findings by September 30.2010 for Executive Secretary review and
approval.
As mentioned above, the requirements in Item 1 were addressed in a letter submitted under separate cover.
Item 2. Perform a video fag of the Cell 1 LOS standpipe down to the T -joint with the slotted coUection pipe and
determine the total downslope distance to the nearest O.1foot.d If anydebrls is observed within the standpipe.
this debris will be removed, If debris is observed. another video log will need to be performed after the debris is
removed to document that the standpipe is free of debris. Both video logs will be performed and submitted for
ORC review and approval by November 1! 2010.
As required by Item 2, Denison identified a camera inspection contractor and completed the initial video log of
the Cell 1 LDS pipe prior to November 1, 2010. Identification of a contractor that was willing to perform the
scope of work took well into October, since those initially contacted were unwilling to expose their equipment to
the aggressive conditions of the Cell 1 system. The one contractor willing to perform the scope of work, RNR

Enterprises ("RNR"), was not available until late October. They completed the video logging on October 22,
2010, and video images were printed and available to Denison's corporate office after that date.
Enclosed with this letter, Denison has provided a copy in CD-ROM format of the continuous video images from
RNR's camera inspection of the Cell 1 LOS. Review of the video images provided the following information:
1. RNR's camera scan extended from the pipe entrance at the top of the cell dike to a depth along the
pipe length of 57.5 feet. The camera eye could not be extended past that depth due to the presence of
material buildup blocking part, but not all, of the pipe. By comparison, the blow tube used in LOS depth
measurements, which is narrower than the camera's probe or snaking device, can be inserted
conSistently to a depth of 69.5 feet along the pipe length.
2. Several segments of older, broken blow tube are visible in the images. The topmost end of the first one
is visible at approximately 33 feet.
3. The intermittent presence of sediment or soil that does not reduce the diameter of the pipe or obstruct
the passage of the camera or the blow tube is visible beginning at 40 feet.
4. A rock or other consolidated mass that can still be bypassed by both the camera and the blow tube is
visible at approximately 52 feet.
5. Buildup of sediment or soil along the bottom half of the pipe which reduces the diameter of the pipe, but
apparently has not obstructed the camera or LOS tube, is visible from approximately 54 feet depth to
57.5 feet depth at which point the camera probe is obstructed and cannot be extended any further.
Path Forward
Based on the images, and consistent with Item 2 of DRC's September 22 letter, Denison has determined that
the LDS pipe does require maintenance to remove the tube debris, and the accumulated sediments,
precipitates, or soil material. Denison's maintenance and engineering staff are currently evaluating different
approaches for clearing the pipe; however, we are concerned about the potential effects from each of the
options under consideration.
We would like the opportunity to discuss the pros and cons of the potential approaches with ORe and receive
ORe's concurrence on a plan and schedule before implementing the selected maintenance action(s).
Therefore, we are in the process but have yet not completed the final steps under Item 2, which require that if
debris is observed, maintenance and a confirmatory video of the cleared pipe are to be submitted by November
1,2010.
We request that ORC review the enclosed CD-ROM images and propose one or more dates when ORe
personnel are available for this discussion.
Please contact the undersigned if you have any questions or require any further information.

Mill -Status Report on Cell 1 Leak Detection system ("LDS") and Transmittal of Confirmatory Video
Docu mentation
This letter report responds to the Utah Division of Radiation Control's September 22, 2010 Conditional Approval
and Confirmatory Action Letter regarding the White Mesa Mill (the "Mill") Cell 1 leak detection system ("LOS")
and Denison Mines (USA) Corp's ("Denison's") telephone conversations with ORC on August 23, September
15, and September 21, 2010. A separate letter which summarized Denison's inspection of the LOS level
measurement process and resolved apparent inconsistencies in Cell 1 LDS depth and liquid level
measurements, as requested in DRC's September 22, 2010 letter, was submitted to DRC on September 30,
2010.
Status of Required Actions in DRC's September 22, 2010 Letter
Item 1. Determine the root cause of the apparent discrepancies of the Estimation of Cell 1 Leakage
Rate, (Table 1) and submit written findings by September 30, 2010 for Executive Secretary review and
approval.
As mentioned above, the requirements in Item 1 were addressed in a letter submitted under separate cover.
Item 2. Perform a video log of the Cell 1 LOS standpipe down to the T -joint with the slotted collection pipe and
determine the total downslope distance to the nearest 0.1 foot. If any debris is observed within the standpipe,
this debris will be removed. If debris is observed, another video log will need to be performed after the debris is
removed to document that the standpipe is free of debris. Both video logs will be performed and submitted for
DRC review and approval by November 1, 2010.
As required by Item 2, the initial video logging was completed on October 22, 2010 by Denison's contractor
RNR Enterprises ("RNR"). A status update report was transmitted to DRC on November 11, 2010 accompanied
by a CD Rom copy of the initial video images of the Cell 1 LOS pipe. Based on the images, and consistent with

Letter to Rusty Lundberg -Cell 1 LOS Update Report
December 27, 2010
Page 2
Item 2 of DRC's September 22 letter, Denison determined that the LOS pipe did require maintenance to remove
the debris, accumulated sediments, precipitates, and soil material. Denison discussed and agreed upon
approached with Mr. Philip Goble of DRC on November 18, 2010. Mr. Goble's email requested that clean out be
completed and video images be submitted to DRC by year-end 2010.
Denison's contractor, RNR, performed the cleanout on December 1 and 2, 2010 using a vacuum truck and ,
while on site, did comparable maintenance in the Cell 3 LOS pipe system. Denison provided DRC a seven-day
notice of the cleanout date and Mr. Goble of DRC was present during most of the cleanout and video work.
Mill environmental personnel also removed from the Cell 1 LOS pipe all broken tubing, to the extent practicable,
leaving one segment of unreachable tubing that does not obstruct operation of the Cell 1 LOS blow pipe
system.
Following the cleanout, Denison's contractor, RNR, performed confirmatory camera scans of both the Cell
LOS and Cell 3 LOS pipes on December 2, 2010.
Enclosed with this letter, Denison is providing a copy in CD-ROM format of the continuous video images from
the pre-cleanout and post-cleanout camera inspection of both the Cell 1 and Cell 3 LOS's. Review of the video
images indicates that the work was successful in removing almost all of the dirt and debris from both LOS's.
Denison respectfully submits that all requirements regarding maintenance of the Cell 1 LOS system have been
completed.
Please contact the undersigned if you have any questions or require any further information.

Sample Delivery Group: C10060176 CASE NARRATIVE
BRANCH LABORATORY SUBCONTRACT ANALYSIS
Tests Associated with Analyst identified as ELI-B were subcontracted to Energy Laboratories Billings Branch, EPA Number
MT00005.
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4°C (±2OC)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand
delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4"C (±2"C)
Report Date: 09/09/10
CASE NARRATIVE
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand
delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven
individual Aroclors. When the results for all seven are ND (not detected), the sample meets EPA compliance criteria for
PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required . If so, ENERGY LABORATORIES will utilize its
branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

RE: LDS
Dear Jo Ann Tischler: Lab Set ID: 1008226
American West Analytical Laboratories received 2 samp lee s) on 8112/2010 for the analyses
presented in the following report.
All analyses were performed in accordance to The NELAC Institute protocols unless
noted otherwise. American West Analytical Laboratories is certified by The NELAC
Institute in Utah and Texas; and is state certified in Colorado and Idaho. Certification
document is available upon request. If you have any questions or concerns regarding this
report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitaion limit (PQL). This is the minimum concentration that can be reported
by the method referenced and the sample matrix. The reporting limit must not be confused
with any regulatory limit. Analytical results are reported to three significant figures for
quality contro I and calculation purposes.
Thank You,
Approved by:
Laboratory Director or designee

Liner Maintenance Provisions-Cells 1, 2, 3 and Roberts Pond Rev. 1 (10-18-09)
Inspections
Tailings cells 1, 2, and 3 are the subject of comprehensive daily inspections which are
conducted by either the Environmental Technician or the Radiation Technician, as well
as once per shift Daily Operations Inspections which are conducted by the Mill Shift
Foreman or other trained personnel designated by the Shift Foreman. The details of these
daily inspections are outlined in Sections 2.1 and 2.2 of the White Mesa Mill Tailings
Management System and Discharge Minimization Technology (DMT) Monitoring Plan.
In each case, these inspections are recorded on inspection forms (Daily Inspection Data
Form and Operating Foreman's Daily Inspection Form, respectively). In addition, non-
recorded Daily Operations Patrols are conducted twice per shift by operations personnel.
With regard to Roberts Pond, this facility is observed on a weekly basis when the
Environmental or Radiation Technician visits the facility for the recording of water levels
at that location.
Training
All individuals performing inspections described in Sections 2.1 and 2.2 of the DMT
Monitoring Plan must have Tailings Management System Training as described in
Appendix C to the DMT Monitoring Plan (Tailings Inspection Training). As and element
of the "Operational Systems" inspection, inspectors are trained and required to observe
the conditions of the PVC liner. Because the PVC liners in Tailings Cells 1, 2 and 3 are
sensitive to sunlight and can degrade as a result of prolonged exposure, inspectors are
cautioned to observe any situation where the liner is exposed. These exposure situations
are considered serious and require immediate attention. Inspectors are trained to cover
small areas of exposure immediately, whereas, larger areas are reported to the radiation
Safety Officer to prompt the issuance of a work order to the Maintenance Department. In
keeping with this inspection requirement, inspectors are trained to observe any
degradation of exposed liners. Such degradation can be that caused by exposure to
sunlight, abrasion due to erosive wave action andlor any rips or tears in the liner material.
Given the fact that the liner material is provided with an earthen cover, erosive damage
andlor rips and tears are unlikely. Inspectors are trained to record all observations of
liner exposure or disrepair on the inspection report, as well as the date and nature of any
repair activity.
Roberts Pond is lined with Hi Density Polyethylene (HDPE) material which is not
sensitive to sun damage and, as such, is not covered with earthen material. In this case
the inspector observes the conditions of the liner to the extent that visual observation is
possible (i.e. above the water level and any visually observable near surface condition).
As is the case for the tailing cell inspections, the liner will be observed for any abrasion
due to erosive wave action andlor any rips or tears in the liner material.
\
Repairs
Repairs to PVC liners in Cells 1, 2 and 3 and to the HDPE liner in Roberts Pond are made
on a case by case basis and usually involves the installation of a repair patch over the
damaged location. PVC patches require the use of glues or adhesive solvents to fuse the
patch to the repair location. HDPE repairs are accomplished by use of an extrusion
welder. Subsequent to any repair of a liner, the repair location will be tested using a
"vacuum box" and soapy water to assure that the repair is acceptable. Tests are
conducted such that test areas overlap by at least 10% of the minimum vacuum chamber
length or at least 2 inches, whichever is greater until the entire seam has been tested.
The observation of bubbles through the repair seam while vacuum (4-8 psi per ASTM
D5641) is being applied to the seam constitutes seam failure and the repair must be
redone until all seams are acceptable. In the case of Cells 1, 2, and 3, after a patch has
been applied, the repair location must be covered with earthen material, again to avoid
exposure to sunlight.! Adequate supplies of PVC and HDPE liner material, repair
material and vacuum test equipment are maintained either in the Mill warehouse or the
maintenance department. The continued availability of these supplies will be verified as
an element of the Quarterly Tailings Inspection conducted by the Radiation Safety
Officer or his designee.
Any leak, hole or other damage to the liners in Cells 1, 2, 3 and the Roberts Pond will be
reported orally to the Executive Secretary within 24 hours of the discovery and in writing
within 5 days of the discovery. The oral and written notifications will include a
notification and description of the failure in accordance with Part I.G.3.(a) of the GWDP
and be in accordance with R317 -6-6.16.C(l) of the regulations. In addition to the
descriptive information about the failure, a plan and schedule for the FML repair will be
included with the notification to the Executive Secretary (in accordance with Part
I.G.3.(c) of the Permit).
Repair Report
Each report will be signed by a Utah licensed professional engineer and will address the
following elements as they apply to the case-by-case repairs which are implemented:
• Repair narrative describing the nature of the damage and the repair work
completed to repair the damage.
• Repair material type used to complete the repair
• Repair material description
• Post repairs test specifications
• Test Methods (ASTM D5641)
• Daily reports during the repair work
• Repair test results
• Quality Assurance/Quality Control Information

as follows:
Step 1)
Where:
Step 2)
Step 3)
Step 4)
Elevation I-Elevation 2 = Head (ft.)
Elevation 1 is the maximum elevation in feet measured during the reporting
period.
Elevation 2 is the FML elevation in feet.
Determine Calculated Action Leakage Rate from Table IA (for CeIl4A) or Table
IB (for Cell 4B) using the head calculated in Step 1 above. If the head calculated
in step 1 above falls between two values in the Head Above Liner System (feet)
column, then the closer of these two values will be used to determine the
Calculated Action Leakage Rate.
Calculate the acres of tailings cell fluids based on the area of the base of the cell,
the head, and the angle of the sideslopes of the cell.
