Review of the 2012 Annual Seep and Spnngs Sampling Report
for Energy Fuels Resources (USA), Inc
White Mesa Uranium Mill, near Blanding, Utah
On November 21, 2012 the Division of Radiation Control ("DRC") received the 2012 Annual Seep and
Spnngs Sampling Report ("Report") for the Energy Fuels Resources (USA), Inc ("EFR") White Mesa
Uranium Mill ("Mill"), near Blanding, Utah For the review of this Report the following regulatory
enforcement documents will be used
• White Mesa Uranium Mill Ground Water Quality Assurance Plan ("QAP")
Revision 7 1, dated May 25, 2012
• Groundwater Discharge Permit No UGW370004 ("Permit") Permit version that was signed on
July 14,2011
• Sampling Plan for Seeps and Spnngs In the Vicinity of the White Mesa Uranium Mill Revision 0
("Plan")
• Utah Department of Environmental Quality Division of Radiation Control Guidance for
Groundwater Split Sample Collection at Uranium Mill Operations August 7,2007
Summary of Compliance
EFR informed DRC m a letter dated May 24,2012, that EFR would be sampling the seeps and spnngs on
June 20,2012 Therefore EFR provided a 15 day notice pnor to sampling as required in Section 3 of the
Plan
The Plan requires the Report to be submitted to DRC on or before December 1, 2012 The Report was
received by DRC on November 21,2012, which met the Plan requirement
The Report met all of the following reporting requirements in Section 6 of the Plan
1) Document the sampling event by means of providing the field sheets recorded at the time of
sampling

2) Copies of all field measurements and laboratory results.
3) Provide a water table contour map that includes water table elevation of all groundwater
monitonng wells at the facility (3"^^ quarter water level measurements) and the elevations of the
phreatic surface observed at each of the seep and spnngs sampled
4) Provide an evaluation and interpretation of the groundwater quality data collected
The DRC staff also observed the EFR staff sample Cottonwood, Entrance and Rum Spnngs Westwater
Seep had a seepage face, but had no standing water so therefore no sample could be collected Coral
Canyon and Corral seeps were found to be dry and therefore no sample could be collected Additional
visits were made to these locations by EFR on June 27,2012 and July 9,2012 to determine if development
attempts with hand tool excavation would yield enough water for sampling The additional two visits did
not mdicate any changes In addition, DRC staff made visits to Westwater Seep in August and October
2012 and there was not enough moisture m the seepage face to collect a water sample Also visited. Coral
Canyon and Corral seeps and they were found to be still dry
DRC staff observed the EFR staff perform the sampling and monitonng on June 20,2012 and after the
DRC review of the Report, it appears that EFR appropnately followed the QAP and Plan
Duplicate Sample Companson
Compansons of duplicate samples analytical results are summanzed m Table 6 in Attachment 1 below To
determine if samples results between two samples from the same laboratory are comparable a relative
percent difference ("RPD") of 20% is acceptable (DRC 2007) To determine if samples results between
two samples from two different laboratones are comparable a RPD of 30% is acceptable (DRC 2007)
The DRC collected a duplicate sample of Cottonwood Spnng with EFR The DRC collected a duplicate of
this spnng and identified it as "Spnng 1" The RPD compansons between the analytical results were
below 20% and therefore comparable EFR collected a duplicate of Cottonwood Spnng and identified it
as "Back Spnng" The RPD compansons between the analytical results were below 20% with the
exception of Chlonde (20 74 %) Because the remainder analytical results compansons between the two
samples had RPD <20% DRC staff feels this one RPD exceedance is not a concem and the analytical
results between the two samples are comparable
The RPD companson between the analytical results for DRC Cottonwood Spnng sample and EFR
Cottonwood Spnng sample were below 30% with the exception of uranium (43 41%) Nether sample
(DRC sample = 14 9 |ig/l, EFR sample = 8 17 |ig/l) exceeded the GWCL for uranium (30 ug/l) Because
the remainder analytical results compansons between the two samples had RPD <30% DRC staff feels this
one RPD exceedance is not a concem and the analytical results between the two samples are comparable
Conclusion on Report
Based on the review of the Report requirements appear to satisfied the Permit, QAP, and Plan requirements
and no further action is required of EFR
Mill Operations Impact on the Seeps and Springs.
The analytical results for the 2011 Seeps and Spnngs Monitonng Event are summanzed in tables 1 through
5 in Attachment 1 below As stated above Westwater Seep, Coral Canyon and Corral seeps were found to
ether dry or not enough moisture to collect a water sample

Cottonwood Spnng
No VOCs or radiologics were detected The only metals detected was uranium that did not exceeded its
GWCL Major ions were detected A companson of the 2009,2010, and 2011 data to the 2012 data shows
that the concentrations of most detected analytes remained approximately the same Overall, the data
reported for Cottonwood Spring appear to indicate no indication of Mill mfluence
Entrance Spnng
No VOCs were detected Gross alpha was detected but did not exceed its GWCL The only metals
detected were iron, selenium, and uranium None exceeded GWCL Major ions were detected A
companson of the 2009,2010, and 2011 data to the 2012 data shows that the concentrations of most
detected analytes remained approximately the same Overall, the data reported for Entrance Spnngs appear
to indicate no indication of Mill mfluence
Ruin Spnng
No VOCs or radiologics were detected The only metals detected were molybdenum, selenium and
uranium None exceeded GWCL Major ions were detected A companson of the 2009,2010, and 2011
data to the 2012 data shows that the concentrations of most detected analytes remained approximately the
same Overall, the data reported for Rum Spnng appear to indicate no indication of Mill influence
Currently, based on the analytical results for the 2012 and all other previous seeps and spnngs sampling
events, it appears that the Mill at this time has not adversely impacted Cottonwood Spnng, Entrance
Spnng, and Ruin Spnng
