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. Anderson:
A number of groundwater monitoring constituents have been placed on accelerated monitoring status
under Part I.G.l of the Energy Fuels Resources (USA) Inc. (“EFRI”) Ground Water Discharge Permit No.
UGW370004 (“GWDP”). Part I.G.l 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 Director make a determination that
accelerated monitoring cease at this time for fluoride in MW-30, sulfate in MW-24, total dissolved solids
(“TDS”) in MW-27, cadmium in MW-25, and uranium in MW-05 for the reasons stated below:
• MW-30 fluoride results have been below the Groundwater Compliance Limit (“GWCL”)
specified in the GWDP for ten consecutive sampling events since the Q4 2015 sampling event.
Per the DWMRC, eight consecutive sample results below the GWCL are needed for the
discontinuance of accelerated monitoring.
• MW-24 sulfate results have been within the GWCL range specified in the GWDP for eight
consecutive sampling events since the Q4 2014 sampling event. Per the DWMRC, eight
consecutive sample results below the GWCL are needed for the discontinuance of accelerated
monitoring.
• MW-27 TDS results have been within the GWCL range specified in the GWDP for eight
consecutive sampling events since the Q4 2014 sampling event. Per the DWMRC, eight
consecutive sample results below the GWCL are needed for the discontinuance of accelerated
monitoring.
• MW-25 cadmium results have been within the GWCL range specified in the GWDP for ten
consecutive sampling events since the Q1 2016 sampling event. Per the DWMRC, eight
consecutive sample results below the GWCL are needed for the discontinuance of accelerated
monitoring.
Letter to Scott Anderson
Removal of Parameters from Accelerated Monitoring
February 10, 2017
Page 2
• MW-5 uranium results have been within the GWCL range specified in the GWDP for eight
consecutive sampling events since the Q4 2014 sampling event. Per the DWMRC, 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 LG. 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 September 2016 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 October 2016 through December 2016 are
provided in the 4th Quarter 2016 Groundwater Monitoring Report and are also included with this letter
for your convenience. It is important to note that the 4th Quarter 2016 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 4th Quarter data are included
in the 4th Quarter 2016 Groundwater Monitoring Report, which will be submitted to DWMRC on or
before March 1, 2017.
If you have any questions or require any further information, please contact the undersigned.
