225 Union Blvd., Suite 600 Lakewood, CO 80228 RE: Energy Fuels Resources (USA) Inc. February 21, 2019, Transmittal of Plan and Time Schedule
Groundwater Discharge Permit No. UGW370004 (Permit)
Dear Ms. Weinel: The Division of Waste Management and Radiation Control (DWMRC) has reviewed the Energy Fuels
Resources (EFR) February 21, 2019 Transmittal of Plan and Time Schedule under Utah Ground Water
Discharge Permit UGW370004 Part I.G.4(c) White Mesa Mill (EFR Plan). The EFR Plan addresses exceedances of the Ground Water Compliance Limit (GWCL) for manganese in monitoring well MW-11. Monitoring Well MW-11 is in out-of-compliance status for manganese per the Permit Part I.G.2. Manganese is therefore required to undergo corrective action per the Permit Part I.G.4.

A Source Assessment Report which will include a more specific source investigation and statistical analysis, as discussed in the EFR Plan Section 4, will be submitted to the Director within 90 days after approval of the EFR Plan.
Based on review of the EFR Plan it appears that the planned activities are appropriate, therefore, the
EFR Plan is hereby approved. If you have any questions, please call Tom Rushing at [phone]. Sincerely,
Rusty Lundberg, Acting Director Division of Waste Management and Radiation Control
