RE: The 2019 Annual Tailings System Wastewater Monitoring Event, Closeout Letter, Ground
Water Quality Discharge Permit Number UGW370004 Dear Ms. Weinel:
On August 21, 2018, the Utah Division of Waste Management and Radiation Control (“Division”)
completed the field inspection of the 2019 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 Cell 4B leak detection system.
The inspection was based on compliance with the:
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 LDS will also be included as part of the review to complete the inspection for the Annual Tailings System Wastewater Monitoring Report due December 1, 2019.
Based on Division staff observation of EFR staff performing the sampling and monitoring on August 21, 2019, 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 21, 2019, Annual Tailings System Wastewater Monitoring Event

Sincerely,

Phil Goble, Uranium Mills and Radioactive Materials Manager Division of Waste Management and Radiation Control PRG/DCH/kb
