Re: Energy Fuels Resources (USA) Inc. Sampling Notice for the Radon Flux Measurements for
Tailings Impoundment 2 at the White Mesa Mill
Dear Mr. Hansen:
Pursuant to the letter from the Utah Division of Waste Management and Radiation Control ("DWMRC")
dated, July 23 , 2014, Energy Fuels Resources (USA) Inc. ("EFRl") is required to measure radon flux at
Tailings Impoundment 2 ("Cell 2") at the White Mesa Mill (the "Mill") semi-annually in accordance with
40 CFR 61 , Appendix B, Method 115. EFRI is providing 30-day notice to DWMRC that the semi-annual
sampling event for the second half of 2023 for Cell 2 will be conducted at the Mill from September 26 -
28, 2023. The measured results will be included in the July through December 2023 Semi-Annual
Effluent Report, due March 1, 2024.
Tellco Environmental of Grand Junction, Colorado will perform approximately 100 measurements on the
cover area of Cell 2 during the sampling event. Provided that there are no rainouts or events that require
remobilization or a delay in measurement, the sampling event is expected to conclude on September 28,
2023.
EFRI will provide safety and radiological orientation for any DWMRC 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.
Yours very truly,
