Box 144880 Salt Lake City, UT 84114-4820 Energy Fuels Resources (USA) Inc. 225 Union Blvd. Suite 600 Lakewood, CO, US, 80228 303 974 2140 www.energyfuels.com C -ZO 1,8 -00 73&5 Div of Waste Management and Radiation Control JUL 2 6 2018 Re: State of Utah Groundwater Discharge Permit ("GWDP") No. UGW370004 Request to Revise Groundwater Quality Assurance Plan ("QAP") Dear Mr. Anderson: Energy Fuels Resources (USA) Inc. ("EFRI") is requesting the addition of an analytical method to Groundwater Quality Assurance Plan ("QAP"), Revision 7.3 dated August 15, 2017. EFRI is requesting the addition of Environmental Protection Agency ("EPA") Method 903.0 Alpha-Emitting Radium Isotopes in Drinking Water as an option for the analysis of Gross Alpha in groundwater samples collected at the White Mesa Mill (the "Mill"). EFRI believes the addition of this Method will have minimum impacts on the Mill data for the following reasons. Method 903.0 will provide data comparable to EPA Method 900.1 currently in use as both report alpha emitting radium isotopes. Both of these EPA methods are published in Prescribed Procedures for Measurement of Radioactivity in Drinking Water EPA Document 600/4-80-032 and are therefore both EPA-approved and accepted methodologies. This method change is being requested to provide the analytical laboratory more flexibility due to updated technology and method improvements. In addition, Method 903.0 may assist in addressing issues due to the dissolved solids content in the Mill groundwater samples. Lastly, the Method change will not have any change on the Reporting Limits specified in the QAP. For ease of review we have provided both redline and clean versions of the QAP page affected by this change. If you should have any questions regarding this plan please contact me.
