SUBJECT: Review of the 2015 Annual Tailings Cells Wastewater Sampling Report
for the Energy Fuels Resources (USA), Inc
White Mesa Uranium Mill, near Blanding, Utah
This is a review of the 2015 Annual Tailings Cells Wastewater Sampling Report dated November
24,2015 (“Report”) for the Energy Fuels Resources (USA), Inc. (“EFR”) White Mesa Uranium
Mill, near Blanding, Utah (“Mill”). For the review of the 2015 Report the following enforcement
documents were used:
• White Mesa Uranium Mill Ground Water Quality Assurance Plan (“QAP”).
Revision 7.2, dated June 6,2012.
• Groundwater Discharge Permit No. UGW370004 (“Permit”). Permit version that was
signed on August 24,2012.
• 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 the Utah Division of Waste Management and Radiation Control (“DWMRC”) in a
letter dated July 27,2015, that EFR would be sampling the tailings cell wastewater on August 4,
2015. The letter from EFR provided notice prior to sampling as required in Part I.E. 10(d)(6) of
the Permit. Part I.E. 10(d) of the Permit requires EFR to sample annually the tailings cells
wastewater in August of each year therefore the August 4,2015 sampling date meets this
requirement.
Section 6 of the Plan requires the Report to be submitted to DWMRC on or before December 1, of
195 North 1950 West • Salt Lake City, UT
Mailing Address: P.O. Box 144850 • Salt Lake City, UT 84114-4850

each year. The Report was received by DWMRC on November 30,2015, which meets the Plan
requirement.
EFR collected tailing cell wastewater samples from Tailings Cells 1, 3,4A, and 4B, and Tailings
Cell 2 Slimes 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. DWMRC staff Dean Henderson collected
a split sample of Tailings Cell 1 and also witnessed EFR staff sample all the other wastewater
sample locations. EFR sampled all available tailing cell wastewater sample locations as required
in Part I.E.10 of the Permit.
The following meet the requirements in Part I.E.10 of the Permit:
• Approved analytical methods.
• Parameter holding times.
• Laboratory receipt Parameter Temperature.
• Certified Laboratory.
• Analyzed for parameters required in Part I.E. 10(d)(1) of Permit.
• Collected duplicate sample.
The Report met all of the following reporting requirements in Section 6 of the Plan:
1) Description of sampling methodology, equipment and decontamination procedures
identify all quality assurance samples, e g trip blanks, equipment, blanks, and
duplicate samples.
2) Analytical data interpretation for each tailing cell, slimes drain, and leak detection
system sample.
3) Written summary and conclusions of analytical results,
4) Table summarizing historic 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 Comparison
Comparisons of duplicate samples analytical results are summarized in Table 7 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 laboratories are comparable
a RPD of 30% is acceptable (DRC 2007). For radiologic duplicate sample a relative error ratio is
calculated (“RER”). A RER <2 is acceptable (DRC 2007).
The RPD comparisons between the EFR analytical results for Tailing Cell 4B LDS and its
duplicate sample “Cell 65” were below 20% with the exception of ammonia (118%) and nitrate
(40%). The RER for gross alpha was 6.9 exceeding the acceptable RER of 2. Because the
remainder analytical results comparisons between the two samples had RPD <20%, DWMRC
