SUBJECT: Review of the 2022 Annual Tailings System Wastewater Monitoring Report
Groundwater Discharge Permit No. UGW370004
for the Energy Fuels Resources (USA), Inc
White Mesa Uranium Mill, near Blanding, Utah
This is the Utah Division of Waste Management and Radiation Control ("Division") review of the 2022
Annual Tailings System Wastewater Monitoring Report dated October 17, 2022 ("Report") for the
Energy Fuels Resources (USA), Inc. ("EFRI") White Mesa Uranium Mill, near Blanding, Utah ("Mill").
For the review of the 2021 Report the following enforcement documents were used:
• The EFR Quality Assurance Plan ("QAP") June 5, 2019 (Revision. 7 .5)
• EFR issued Ground Water Quality Discharge Permit No. UGW370004 ("Permit"). Permit
version that was signed on March 19, 2019.
• Tailings and slimes Drain Sampling Program ("Plan") Revision 3.0 dated July 8, 2016.
Summary of Compliance
Section 6 of the Plan requires the Report to be submitted to the Division on or before December 1, of
each year. The date of the Report is October 17, 2022, and it was received by the Division on October
19, 2022, which meets the Plan requirement.
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. I 0( d)( 1) of Permit.
• Collected duplicate sample.
The following meet the 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 sample results between two samples from the same laboratory are comparable a relative
percent difference ("RPD ") of 20% is acceptable. To determine if sample results between two samples
from two different laboratories are comparable a RPD of 30% is acceptable. For radiologic duplicate
sample a relative error ratio is calculated ("RER"). A RER <2 is acceptable.
EFRI Duplicate Sample Comparison
The RPD comparisons between the EFRI analytical results for Cell 4A LDS and its duplicate sample
"Cell 65" were below 20% except for acetone. The RER for gross alpha was above the acceptable RER
of2 (see Table 7 below). A reasonable cause to the duplicate result for acetone exceeding the RPD of
20% and RER of 2, maybe due to matrix interference and/or sample dilution caused by the high
concentrations in the wastewater samples. Because the remainder analytical results comparisons
between the two samples had RPD <20%, Division staff feels these RPD exceedances are not a concern
and the analytical results between the two samples are comparable.
Division Duplicate Sample Comparison
The Division collected a duplicate sample of Tailings Cell I with EFRI. The Division also collected a
duplicate of this location and identified it as "Cell 6". The RPD comparisons between the Division
analytical results for Tailing Cell 1 and its duplicate sample Cell 6 were below 20% except for nitrate
and beryllium and the RER for gross alpha was above 2. A reasonable cause to the two duplicate results
exceeding the RPD of20% and RER of2 may be due to matrix interference and/or sample dilution
caused by the high concentrations in the wastewater samples. Because the remainder analytical results
comparisons between the two samples had RPD <20%, the Division staff feels these RPD exceedances
are not a concern and the analytical results between the two samples are comparable (see Table 7
below).
Division Sample Comparison to EFRI
The RPD comparison between the analytical results for the Division samples Cell 1 and Cell 6 to EFRI
Cell 1 sample are found on Table 7 below. In comparing these samples all RPD were below 30% except
for TDS and chloride and the RER for gross alpha was above 2. A reasonable cause to the two duplicate
results exceeding the RPD of 30% and the RER above 2 may be due to matrix interference and/or
Page 3
sample dilution caused by the high concentrations in the wastewater samples. Because the remainder
analytical results comparisons between the two samples had RPD <30%, the Division staff feels these
RPD exceedances are not a concern and the analytical results between the two samples are comparable
(see Table 7 below).
The analytical results for the 2022 Tailings Cells Wastewater Monitoring Event are summarized in
tables 1 through 8 in Attachment 1 below. Based on the tailings cells wastewater sampling analytical
results all concentrations for the 2022 tailing cell wastewater monitoring event appear to have relatively
similar concentrations to historic monitoring events.
The purpose for annual monitoring of the tailings cells wastewater is to inventory Mills contaminants
and concentrations. This annual 2022 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, EFRI conducted voluntary analyses on the
wastewater on August 24, 2022, 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, and specific gravity (data summarized in Table 8 below). This analytical data of the wastewater is
for informational purposes only.
Conclusion of Report
Based on Division staff observation of EFRI staff performing the sampling and monitoring on August
24, 2022, and after the Division review of the Report, it appears that EFRI appropriately followed the
requirements in the Permit, QAP and Plan and no further action is required ofEFRI. Therefore, a letter
will be drafted for the Division signature, notifying EFRI of the review and closing out of for the 2022
Annual Tailings System Wastewater Monitoring Report Monitoring Report.
