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. ("EFRJ") Ground Water Discharge Permit No.
UGW370004 ("GWDP"). Part LG. 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, EFRJ 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-I I for the reasons stated below:
• MW-I 1 TDS results have been within the Groundwater Compliance Limit ("GWCL") specified
in the GWDP for eight consecutive sampling events starting in November 2022. Per the UDEQ,
eight consecutive sample results below the GWCL are needed for the discontinuance of
accelerated monitoring.
Once removed from accelerated monitoring status, this constituent, 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 1.
The analytical laboratory reports for the foregoing results up to and including March 2023 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 April 2023 through June 2023 will be provided in the
upcoming 2nd Quarter 2023 Groundwater Monitoring Report and are also included with this letter for
your convenience. It is important to note that the 2nd 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 2nd Quarter data will be included in the
2nd Quarter 2023 Groundwater Monitoring Report, due September 1, 2023.
