RE:Close out Letter Regarding the November5, 2024,Utah Division of Waste Management and Radiation Control, Ground Water Module 65, Storm Water Inspection at the White Mesa Uranium MillUtah
Groundwater Discharge Permit No. UGW370004.Radioactive Material License Number UT1900479
Dear Ms. Weinel:
The Utah Division of Waste Management and Radiation Control conducted a storm water inspection at the Energy Fuels Resources (USA) Inc. (EFR)White Mesa Uranium Mill (Mill)on November5,
2024.
Based on review of onsite storm water related documents and forms and a site walk-through inspection of storm water management at the Mill, it appears that all requirements of the Mill
Groundwater Discharge Permit (including the currently approved EFR Spill Prevention, Control and Countermeasures Plan, and Storm Water Best Management Practices Plan) are being adequately
addressed. No violations were identified during the inspection. The Division does maintain a concern about the condition of the secondary containmentfor the HCl tanks. These concerns
were expressed in response to Energy Fuels’ second quarter 2024 DMT performance report, dated July 31, 2024 (DRC-2024-006458). The Division recommends continued monitoring and evaluationof
the HCl secondary containment to ensure that it is providing an impervious barrier.
Note that a close out conference with EFR representatives Garrin Palmer andTanner Holliday was conducted after the inspection. Based on the inspection, the 2024 Storm Water Inspection
(Groundwater Inspection Module 65) is hereby closed out.
If you have any questions, please call Chris Leahy at [phone].
Sincerely,
Adam Wingate, Uranium Recovery Section Manager
Division of Waste Management and Radiation Control
