SUBJECT: Review of the 2016 Annual Tailings Cells Wastewater Sampling Report
This is a review of the 2016 Annual Tailings Cells Wastewater Sampling Report dated October
31, 2016 (“Report”) for the Energy Fuels Resources (USA), Inc. (“EFR”) White Mesa Uranium
Mill, near Blanding, Utah (“Mill”). For the review of the 2016 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 9, 2016, that EFR would be sampling the tailings cell wastewater on August 24,
2016. 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 24, 2016 sampling date meets this
requirement. Because of DWMRC staff had scheduling conflicts the tailings cell wastewater
sampling event occurred on August 30, 2016.

Section 6 of the Plan requires the Report to be submitted to DWMRC on or before December 1, of
each year. The Report was received by DWMRC on November 2, 2016, 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 (see photograph in attachment 2),'and Tailings Cells 4A and 4B Leak
Detection Systems (“LDS”). The EDS for Tailings Cells 1, 2, and 3 were dry and not sampled.
DWMRC staff Dean Henderson collected a split sample of Tailings Cell 4A 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).
EFR Duplicate Sample Comparison
The RPD comparisons between the EFR analytical results for Tailing Cell 3 and its duplicate
sample “Cell 65” were below 20% with the exception of chromium (23%), cobalt (36%), lead
(44%) nickel (56%), bis(2-etyhexyl) phthalate (56%), TDS (45%) and calcium (182%). The RER
Page 3
for gross alpha was 209 exceeding the acceptable RER of 2. Because the remainder analytical
results comparisons between the two samples had RPD <20%, DWMRC staff feels these RPD
exceedances are not a concern and the analytical results between the two samples are comparable.
DWMRC Duplicate Sample Comparison
The DWMRC collected a duplicate sample of Tailings Cell 4A with EFR. The DWMRC also
collected a duplicate of this location and identified it as “Cell 6”. The RPD comparisons between
the DWMRC analytical results for Tailing Cell 4A and its duplicate sample Cell 6 were below
20% with the exception of iron (50%), mercury (24%), Benzoic acid (42%) calcium (51%),
magnesium (21%), potassium (177%) and sodium (43%). Because the remainder analytical
results comparisons between the two samples had RPD <20%, DWMRC staff feels these RPD
exceedances are not a concern and the analytical results between the two samples are comparable.
DWMRC Sample Comparison To EFR
The RPD comparison between the analytical results found on Table 7 for the DWMRC Cell 4A
and Cell 6 sample and EFR Cell 4A sample were below 30% with the exception of the analytical
results for calcium (199%) and potassium (173 %). Because the remainder analytical results
comparisons between DWMRC and EFR samples had RPD <30%, DWMRC staff feels these
RPD exceedances are not a concern and the analytical results between the two samples are
comparable.
The purpose for annual monitoring of the tailings cells wastewater at the Mill is to inventory their
contaminants and concentrations. This annual 2016 monitoring event for the tailing cells
wastewater has accomplished this purpose.
Additional Samples for Radiologies, Viscosity, and Specific Gravity
Although not required in the QAP, Permit, or Plan EFR conducted voluntary analyses on the
wastewater on August 30, 2016 and provided this information in the Report. Samples were
analyzed for radium-226, thorium-228, thorium-230, thorium-232, uranium 233/234, uranium
235/236, uranium-238, kinematic viscosity, and specific gravity (data summarized in Table 9
below). This analytical data of the wastewater are for informational purposes only.
2016 Mill Operations Impact on the Wastewater in Tailings Cells
The analytical results for the 2016 Tailings Cells Wastewater Monitoring Event are summarized
in tables 1 through 8 in Attachment 1 below. Figure showing a photograph of sampling event are
shown in Attachment 2. Based on the tailings cells wastewater sampling analytical results all
concentrations for the 2016 tailing cell wastewater monitoring event appear to have relatively
similar concentrations to historic monitoring events. Therefore, the addition of wastewater to the
tailings cells in 2016 appears not have impacted historic wastewater concentrations in the tailing
cells.
Conclusion on Report
Based on DWMRC staff observation of EFR staff performing the sampling and monitoring on
August 30, 2016 and after the DWMRC review of the Report, it appears that EFR appropriately
followed the requirements in the Permit, QAP and Plan and no further action is required of EFR.
