Re: State of Utah Ground Water Discharge Permit No. UGW370004
White Mesa Uranium Mill -Removal of Certain Groundwater Monitoring Parameters
from Accelerated Monitoring Status
Dear Mr. Hansen:
A number of groundwater monitoring constituents have been placed on accelerated monitoring status
under Part LG. I of the Energy Fuels Resources (USA) Inc. ("EFRI") Ground Water Discharge Permit No.
UGW3 70004 ("GWDP"). Part I.G. I provides that such accelerated monitoring shall continue until
compliance status of the facility can be determined by the Director.
Based on the accelerated monitoring results to date, EFRI requests the Division of Waste Management
and Radiation Control ("DWMRC") make a determination that accelerated monitoring cease at this time
for Total Dissolved Solids ("TDS") in MW-25 and selenium and uranium in MW-12 for the reasons
stated below:
• MW-25 TDS results have been within the Groundwater Compliance Limit ("GWCL") specified
in the GWDP for eleven consecutive sampling events starting in May 2022. Per the UDEQ,
eight consecutive sample results below the GWCL are needed for the discontinuance of
accelerated monitoring.
• MW-12 selenium results have been within the GWCL specified in the GWDP for nine
consecutive sampling events starting in QI 2021. Per the UDEQ, eight consecutive sample
results below the GWCL are needed for the discontinuance of accelerated monitoring.
• MW-12 uranium results have been within the GWCL specified in the GWDP for eight
consecutive sampling events starting in Q2 2021. Per the UDEQ, eight consecutive sample
results below the GWCL are needed for the discontinuance of accelerated monitoring.
Once removed from accelerated monitoring status, these constituents, like all other constituents, would be
subject to future accelerated monitoring under Part I.G.1 of the GWDP, should circumstances warrant.
To assist in your evaluation of the foregoing, we have included a summary of the accelerated sampling
results since the initial sample result that triggered accelerated monitoring in Table I.

The analytical laboratory reports for the foregoing results up to and including December 2022 are
included in the Quarterly Groundwater Monitoring Reports, all of which have been provided to DWMRC.
Copies of the analytical laboratory reports for the results for January 2023 through March 2023 will be
provided in the upcoming 1st Quarter 2023 Groundwater Monitoring Report and are also included with
this letter for your convenience. It is important to note that the 1st Quarter 2023 monitoring results
included with this letter have been evaluated per the DWMRC approved QAP and the GWDP and all
field and laboratory quality control parameters are acceptable. The evaluations of the 1st Quarter data
will be included in the 1st Quarter 2023 Groundwater Monitoring Report, due June 1, 2023.
If you have any questions or require any further information, please contact the undersigned.
Yours truly,
