225 Union Blvd., Suite 600 Lakewood, CO 80228 RE: The 2020 Annual Tailings System Wastewater Monitoring Event, Closeout Letter, Ground Water Quality Discharge Permit Number UGW370004
Dear Ms. Weinel: On August 19, 2020, the Utah Division of Waste Management and Radiation Control (“Division”)
completed the field inspection of the 2020 Annual Tailings System Wastewater Monitoring Event by
Energy Fuels Resources (USA) Inc. (“EFR”). This inspection also included the collection of a split- sample by the Division of tailings wastewater in the Tailings Cell 4B. The inspection was based on compliance with the following:
1. White Mesa Uranium Mill Ground Water Quality Assurance Plan (“QAP”) Revision 7.4, dated July 23, 2018. 2. Groundwater Discharge Permit No. UGW370004 (“Permit”), dated March 19, 2019. 3. Tailings and slimes Drain Sampling Program (“Sampling Plan”) Revision 3.0 dated July 8, 2016.

The findings of this inspection and results of the analytical analysis for the Division split sample of the wastewater in Cell 4B will also be included as part of the review to complete the inspection for the Annual Tailings System Wastewater Monitoring Report due December 1, 2020. (Over)

Based on Division staff observation of EFR staff performing the sampling and monitoring on
August 19, 2020, it appears that EFR staff is in compliance with field sampling requirements in the
Permit, QAP and Sampling Plan. This letter constitutes a closeout of the August 19, 2020, Annual Tailings System Wastewater Monitoring Event If you have any questions, please contact Dean Henderson at [phone].
