Box 144880 Salt Lake City, UT 84114-4880 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. 1 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 uranium in MW-30, vanadium in MW-28, and gross alpha minus Rn and U (“gross alpha”) in MW-32 for the reasons stated below: • MW-30 uranium results have been below the Groundwater Compliance Limit (“GWCL”) specified in the GWDP for eight consecutive sampling events since January 2016. Per the DWMRC, eight consecutive sample results below the GWCL are needed for the discontinuance of accelerated monitoring. • MW-28 vanadium results have been within the GWCL range specified in the GWDP for nine consecutive sampling events since the Q2 2014 sampling event. Per the DWMRC, eight consecutive sample results below the GWCL are needed for the discontinuance of accelerated monitoring. • MW-32 gross alpha results have been within the GWCL range specified in the GWDP for eight consecutive sampling events since the Q3 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 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.
