Re: Energy Fuels Resources (USA) Inc. Notification of NESHAPs Radon Flux Measurements for Tailings lmpoundment 3 at the White Mesa Mill
Dear Mr. Bird:
Energy Fuels Resources (USA) Inc. ("EFRI") plans to perform a sampling event for NESHAPs Radon
Flux measurements for the second half of 2022 at Tailings Impoundment 3 at the White Mesa Mill from
October 4, 2022 through October 6, 2022. Per 40 CFR 61.253, EFRI is permitted to monitor Radon Flux one or more times per year. EFRI is sampling Tailings Impoundment 3 on a semi-annual frequency in 2022.
Tellco Environmental of Grand Junction, Colorado ("Tellco") will perform approximately 100
measurements on the beach and cover area of Tailings Impoundment 3 during the sampling event. These
measurements will be performed in accordance with methods and procedures set forth in 40 CFR Part 61, Appendix B, Method 115. Provided that there are no rainouts or events that require remobilization or a delay in measurement, the sampling event for Tailings Impoundment 3 is expected to conclude on October 6, 2022.
EFRI will provide safety and radiological orientation for any Utah Department of Air Quality personnel
observing this event. This orientation will be required before any individual enters the Mill Restricted
Area. Individuals monitoring this event should bring their own mandatory Personnel Protective
Equipment as required at the Mill, specifically, safety glasses, hardhats, and steel-toed shoes.
If you have any questions or require assistance, please contact me at 303-389-4134; or Mr. Garrin Palmer, at 435-678-4114.
