MEMORANDUM
DRC -2020-0204-
TO: Phil Goble /2 /0/7
FROM: Dean Henderson aPC'i 6 )
DATE: December 30, 2020
SUBJECT: Review of the 2020 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 a review of the 2020 Annual Tailings System Wastewater Monitoring Report dated November
20, 2020 ("Report") for the Energy Fuels Resources (USA), Inc. ("EFR") White Mesa Uranium Mill,
near Blanding, Utah ("Mill"). For the review of the 2020 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
EFR informed the Utah Division of Waste Management and Radiation Control ("Division") in a letter
dated June 10, 2020, that EFR would be sampling the tailings cell wastewater on August 19, 2019. 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 19, 2020 sampling date meets this requirement.
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 November 17, 2020 and it was received by the Division on
November 20, 2020, which meets the Plan requirement.

EFR staff Deen Lyman and Tanner Holliday carried out the monitoring activities. EFR collected
tailings cell wastewater samples from Tailings Cells 1, 4A, and 4B, and Tailings Cell 2 Slimes Drain,
and Tailings Cells 4B and 4B Leak Detection Systems ("LDS") as required in Part I.E.10 of the Permit.
Tailings Cell 3 is now completely covered with soil and there was no wastewater exposed to be sampled.
The LDS for Tailings Cells 1, 2, and 3 were dry and not sampled. Division staff Dean Henderson
collected a split sample of Tailings Cell 4A and also witnessed EFR staff sample all the other
wastewater sample locations. The Division staff observations of EFR staff performing the monitoring
and sampling activities is documented in August 24, 2020 memorandum [2020 Memo] (DRC-2020-
016721) and a August 25, 2020 close out letter (DRC-20-014422). The 2020 Memo stated, "Based on
Division staff observation of EFR staff performing the sampling and monitoring on August 20, 2020, it
appears that EFR appropriately followed the field requirements in the Permit, QAP and Sampling
Plan."
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 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 samples results between two samples from the same laboratory are comparable a relative
percent difference ("RPD") of 20% is acceptable. To determine if samples 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.
EFR Duplicate Sample Comparison
The RPD comparisons between the EFR analytical results for Cell 4A and its duplicate sample "Cell 65"
were below 20% with the exception of thallium. The RER for gross alpha was below the acceptable
RER of 2 (see Table 7 below). Because the remainder analytical results comparisons between the two
Page 3
samples had RPD <20%, DWMRC 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 4B with EFR. 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 4B and its duplicate sample Cell 6 were below 20% with the exception
of chloride, fluoride, and sodium. 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). The RER for gross
alpha was below acceptable RER of 2.
Division Sample Comparison to EFR
The RPD comparison between the analytical results for the Division samples Cell 4B and Cell 6 to EFR
Cell 4B sample are found on Table 7 below. In comparing these samples all RPD were below 30% with
the exception of silver, thallium, acetone, calcium, chloride, and fluoride. The RER for gross alpha
exceeded the acceptable RER of 2.
The purpose for annual monitoring of the tailings cells wastewater is to inventory Mills contaminants
and concentrations. This annual 2020 monitoring event for the tailing cells wastewater has
accomplished this purpose.
Additional Samples for Radiologics, Viscosity, and Specific Gravity
Although not required in the QAP, Permit, or Plan, EFR conducted voluntary analyses on the
wastewater on August 19, 2020 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 are
for informational purposes only.
2020 Mill Operations Impact on the Wastewater in Tailings Cells
The analytical results for the 2020 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 2020 tailing cell wastewater monitoring event appear to have relatively
similar concentrations to historic monitoring events.
Conclusion of Report
Based on Division staff observation of EFR staff performing the sampling and monitoring on August 19,
2020 and after the Division 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. Therefore, a letter
will be drafted for the Division signature, notifying EFR of the review and closing out of for the 2020
Monitoring Report.
