Review of the 2012 Annual Tailings Cells Wastewater Sampling Reports
for the Energy Fuels Resources (USA), Inc
White Mesa Uranium Mill, near Blanding, Utah
This IS a review of the 2012 Annual Tailings Cells Wastewater Sampling Report dated November
30, 2012 ("Report") for the Energy Fuels Resources (USA), Inc ("EFR") White Mesa Uranium
Mill, near Blanding, Utah ("Mill") For the review of the 2012 Report the following enforcement
documents will be use
White Mesa Uramum 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
• Utah Department of Environmental Quality Division of Radiation Control Guidance for
Groundwater Split Sample Collection at Uranium Mill Operations, August 7, 2007
• Tailings and slimes Drain Sampling Program (hereafter "Plan") Revision 2 1 dated July
,30, 2012
Summary of Compliance
EFR informed DRC m a letter dated July 12, 2012, that EFR would be sampling the tailings cell
wastewater on August 14, 2012 Although the samples were collected on August 15, 2012 the
letter from EFR provided a 30 day notice pnor to sampling as required in Part IE 10(d)(6) of the
Permit In Part IE 10(d) of the Permit requires EFR to annually sample the tailings cell waste
water in August each year therefore the August 15,2012 sampling date meets this requirement
In Section 6 of 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

EFR collected tailing cell wastewater samples from Tailings Cells 1,3,4A, and 4B, and Tailings
Cell 2 Shmes Drain, and Tailings Cells 4A and 4B Leak Detection Systems ("LDS") The LDS
for Tailings Cells 1, 2, and 3 were dry and not sampled DRC staff Dean Henderson collected a
split sample of Tailing Cell 4B and also witnessed EFR staff sample all the other wastewater
sample locations EFR has sampled all available tailing cell wastewater sample locations as
required in Part IE 10 of the Permit
The following meet the requirements in Part IE 10 of the Permit
• Approved analytical methods
• Parameter holding times.
• Laboratory receipt Parameter Temperature
• Certified Laboratory
• Analyzed for parameters required in Part IE 10(d)(1) of Permit
• Collected duplicate sample
The Report met all of the following reporting requirements m Section 6 of the Plan
1) Descnption of sampling methodology, equipment and decontamination procedures
identify all quality assurance samples, e g tnp blanks, equipment, blanks, duplicate
samples
2) Analytical data interpretation for each tailing cell, slimes drain, and leak detection system
sample
3) Wntten summary and conclusions of analytical results,
4) Table summanzing histonc analytical results,
5) QA evaluation
6) All field data sheets accompanying the sampling event
7) Copies of the laboratory reports
8) Tailings and Slime Drains System Sample Locations Map
Duplicate Sample Companson
Compansons of duplicate samples analytical results are summanzed in 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 Tailings Cell 4B with EFR. The DRC collected a
duplicate of this location and identified it as "Cell 6" The RPD compansons between the
analytical results were below 20% with the exception of Acetone (21.05%), Tetrahydrofiiran
["THF"](25.78%) and Calcium (27 06%) Because the remainder analytical results compansons
between the two samples had RPD <20% DRC staff feels these RPD exceedances is not a concem
and the analytical results between the two samples are comparable. EFR collected a duplicate of
Tailing Cell 2 Slimes Drain and identified it as "Cell 65" The RPD compansons between the
analytical results were below 20% with the exception of Mercury (23 53 %) Because the
Page 3
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 Tailing Cell 4B sample and EFR
Tailing Cell 4B were below 30% with the exception of Ammonia (107 02%), Mercury (60 65%),
Thallium (81 45%), Acetone (56 49%), Chlorofomi (55 20%), THF (37 36%), Fluonde (190 21%)
TDS (39 79) and Calcium (72 24%) The purpose for annual momtonng of the tailings cells
wastewater at the Mill is to inventory the contaminants and their concentrations Therefore, even
though duplicate sample shows that the above 9 parameters exceeded the RPD of 30% the purpose
for annual monitonng the tailing cells wastewater was accomplished and no action is
recommended
2012 Mill Operations Impact on the Wastewater in Tailings Cells
The analytical results for the 2012 Tailings Cells Wastewater Momtonng Event are summanzed
in tables 1 through 5 in Attachment 1 below Based on the tailings cells wastewater sampling
analytical results all concentrations for the 2012 tailing cell wastewater momtonng event appear
to have relatively similar concentrations to histonc monitonng events Therefore, added
wastewater to the tailings cells in 2012 appears not had impacted histonc wastewater
concentrations in the tailing cells
Conclusion on Report
Based on DRC staff observation of EFR staff performing the sampling and monitonng on August
15,2012 and after the DRC review of the Report, it appears that EFR appropnately followed the
requirements m the Permit, QAP and Plan and no fiirther action is required of EFR
