V ww.energyfuels.corn Div of Waste Management and Radiation Control VIA PDF AND FEDERAL EXPRESS Ty L. Howard Director Division of Waste Management and Radiation Control State of Utah Department of Environmental Quality 195 North 1950 West P.O. Box 144880 Salt Lake City, UT 84116 FEB - 4 2020 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. Howard: 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.1 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 field pH in MW-30 and MW-36, cadmium in MW-25, and ammonia in MW-26 for the reasons stated below: • MW-30 field pH results have been within the Groundwater Compliance Limit ("GWCL") specified in the GWDP for ten consecutive sampling events since February 2019. Per the UDEQ, eight consecutive sample results below the GWCL are needed for the discontinuance of accelerated monitoring. • MW-36 field pH results have been within the GWCL range specified in the GWDP for nine consecutive sampling events since the Q1 2019 sampling event. Per the UDEQ, eight consecutive sample results below the GWCL are needed for the discontinuance of accelerated monitoring. • MW-25 cadmium results have been below the GWCL specified in the GWDP for nine consecutive sampling events since Q1 2019. Per the UDEQ, eight consecutive sample results below the GWCL are needed for the discontinuance of accelerated monitoring. • MW-26 ammonia results have been below the GWCL specified in the GWDP for nine consecutive sampling events since Q1 2019. Per the UDEQ, eight consecutive sample results below the GWCL are needed for the discontinuance of accelerated monitoring. Letter to Ty L. Howard Removal of Parameters from Accelerated Monitoring January 31, 2020 Page 2 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. Field pH measurements will continue to be recorded for all samples collected, including any accelerated monitoring completed for other constituents as required. Upon DWMRC approval of this request, field pH measurements will no longer be tracked and reported as part of the quarterly Exceedance Notice, but will return to the routine reporting in the Quarterly Groundwater Monitoring Reports. 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 December 2019 are included in the Quarterly Groundwater Monitoring Reports, all of which have been provided to DWMRC. Copies of the analytical laboratory reports and the field sheets for the results for October 2019 through December 2019 will be provided in the upcoming 4th Quarter 2019 Groundwater Monitoring Report and are also included with this letter for your convenience. It is important to note that the 4th Quarter 2019 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 will be included in the 4th Quarter 2019 Groundwater Monitoring Report, due March 1, 2020. If you have any questions or require any further information, please contact the undersigned.
