Review of the February 20, 2023, Annual Seeps and Springs Sampling Report for Energy Fuels
Resources (USA), Inc. White Mesa Uranium Mill, near Blanding, Utah
On February 20, 2023 , the Division of Waste Management and Radiation Control ("Division") received the
February 23, 2022 Annual Seep and Springs Sampling Report ("Report") [eDocs: DRC-2023-001738] for the
Energy Fuels Resources (USA), Inc. ("EFRI") White Mesa Uranium Mill ("Mill"), near Blanding, Utah. For the
review of this Report the following regulatory enforcement documents will be used:
• White Mesa Uranium Mill Ground Water Quality Assurance Plan ("QAP").
Revision 7.5 dated June 6, 2019.
• Groundwater Discharge Permit No. UGW370004 ("Permit"). Permit version that was signed on March
19, 2019.
• Sampling Plan for Seeps and Springs in the Vicinity of the White Mesa Uranium Mill. Revision 2. July 8,
2016 ("Sampling Plan").
• Utah Department of Environmental Quality Division of Radiation Control Guidance for Groundwater
Split Sample Collection at Uranium Mill Operations, August 7, 2007 (2007 Guidance).
Report Riverview
The Report met all the following reporting requirements in Section 6 of the Sampling Plan:
1) Documented the sampling event by means of providing the field sheets recorded at the time of sampling.
2) Provided copies of all field measurements and laboratory results.
3) Provided a water table contour map that includes a water table elevation of all groundwater monitoring
wells at the facility (3rd quarter 2021 water level measurements) and the elevations of the phreatic surface
observed at each of the seep and springs sampled.
4) Provided an evaluation and interpretation of the groundwater quality data collected.

Duplicate Sample Comparison
Comparisons of duplicate samples analytical results are summarized in Tables 6 in 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 (2007 Guidance). To determine if sample results between two samples
from two different laboratories are comparable a RPD of 30% is acceptable (2007 Guidance). For radiologies, to
determine if sample results between two samples or two laboratories are comparable, a replicate error ratio
("RER") of:::; 2 is acceptable (2007 Guidance).
EFRl Duplicate Sample Comparison
EFRl collected a duplicate of Cottonwood Spring and identified it as "Back Spring". The RER comparisons for
gross alpha were below 2. The RPD comparisons between the analytical results were all below 20%. (see Table
6).
Division Duplicate Sample Comparison
The Division collected a water sample from Cottonwood Spring and a duplicate sample identified it as "Spring
6". The RER comparisons for gross alpha were below 2. The RPD comparisons between the analytical results
were all below 20%. (see Table 6 below).
Division Sample Comparison to EFRl
The RER and RPD comparisons were made between the analytical results for the Division Cottonwood Spring
and Spring 6 samples with EFRl sample of Cottonwood Spring. The RER comparisons for gross alpha were all
below 2. The RPD comparisons between the analytical results were all below 30% (see Table 6 below).
The analytical results for the 2022 seeps and springs monitoring event are summarized in Tables 1 through 6 in
Attachment 1 below.
Cottonwood Spring
Nutrients ammonia and nitrate concentrations were found to be non-detect, which is typical of historic
concentrations. The only metals detected was uranium below its GWQS and typical of historic concentrations.
No VOCs were detected. A comparison of the historic data since 2009 data shows that the concentrations of most
detected analytes remained approximately the same with no concentrations exceeding GWQS. Gross alpha was
found below the GWQS. Overall, the data reported Cottonwood Spring sample results appear to show no
indication of Mill impact (see tables 1 and 2 below).
Entrance Spring
Nutrients ammonia and nitrate showed non-detectable and 0.2 mg/I respectively which is well below GWQS and
typical of historic concentrations. The only metals detected were arsenic, chromium, cobalt, iron, manganese,
molybdenum, nickel, selenium, uranium and vanadium and all below GWQS. All metals were typical of historic
concentrations except for cobalt, chromium, nickel, and vanadium were detected for the first time. This is due to
historic lower RLs resulting in detections being reported in 2022 that have never been reported before. Therefore,
these detections may not be result of increasing concentrations but are the result in historic lower RLs. No VOCs
concentrations were detected. Gross alpha was below GWQS. With the exception of the first-time detection of
metals reported above, historic data since 2009 data shows that the concentrations of most detected analytes
remained approximately the same with no concentrations exceeding GWQS. Overall, the data reported for
Entrance Spring sample results appear to show no indication of Mill impact (see tables 1 and 3 below).
Ruin Spring and Its Duplicate Sample Back Spring
Ammonia and nitrate had a non-detectable and detectable concentration well below GWQS and typical of historic
concentrations. The only metals detected was chromium, molybdenum, nickel, selenium, silver, uranium and
vanadium and all below GWQS. All metals were typical of historic concentrations except for chromium, nickel,
and vanadium were detected for the first time. This is due to historic lower RLs resulting in detections being
reported in 2022 that have never been reported before. Therefore, these detections may not be the result of
increasing concentrations but are the result in historic lower RLs. No VOCs concentrations detected. Gross alpha

was below GWQS. With the exception of the first-time detection of metals reported above a comparison of the
historic data since 2009 shows that the concentrations of most detected analytes remained approximately the same
with no concentrations exceeding GWQS. Overall, the data reported for Ruin Spring sample results appear to
show no indication of Mill impact (see tables 1 and 4 below).
Westwater Spring
Ammonia and nitrate had non-detectable concentrations. The only metals detected were arsenic, chromium,
cobalt, iron, manganese, molybdenum, nickel, selenium, vanadium, and uranium and all below GWQS. All
metals were typical of historic concentrations except for arsenic, chromium, and nickel were detected for the first
time. This is due to historic lower RLs resulting in detections being reported in 2022 that have never been
reported before. Therefore, these detections may not be the result of increasing concentrations but are the result in
historic lower RLs. No VOC was detected, and gross alpha was below GWQS. Overall, the data reported for
Ruin Spring sample results appear to show no indication of Mill impact (see tables 1 and 5 below).
Conclusions on Compliance with the Permit and QAP
Per the Division review it appears that the Report complies with Permit, QAP, and Plan. Therefore, a letter will
be drafted notifying EFRI of the review and closing out of for the Seeps and Springs 2022 Monitoring Report ..
