Re: Energy Fuels Resources (USA) Inc. Notification of Rescheduling of NESHAPs Radon Flux
Measurements for Tailings Impoundment 3 at the White Mesa Mill
Dear. Mr. Bird:
On September 4, 2019, Energy Fuels Resources (USA) Inc. ("EFRI") submitted a 30-day notice regarding plans
to perform a sampling event for NESHAPs Radon Flux measurements for the third event of 2019 at Tailings
Impoundment 3 at the White Mesa Mill from October 7 - 9, 2019. However, due to a scheduling issue, EFRI is
rescheduling the sampling event. This letter serves as notification that the third 2019 NESHAPs Radon Flux
sampling event for Tailings Impoundment 3 is being rescheduled from October 7 - 9, 2019 to October 8 - 11,
2019.
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 11, 2019.
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. Terry Slade,
Radiation Safety Officer, at 435-678-4128.
Yours very t ly,
