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 July 30, 2018, 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 quarter of 2018 at Tailings Impoundment 3 at the White Mesa Mill from September 1 - 4,
2018. However, due to the holiday schedule at the Mill, EFRI is rescheduling the sampling event.
This letter serves as notification that the third quarter 2018 NESHAPs Radon Flux sampling
event for Tailings Impoundment 3 is being rescheduled from September 1 - 4, 2018 to September
10 - 13, 2018.
As stated in the July 30, 2018 letter, per 40 CFR 61.253, EFRI is permitted to monitor Radon
Flux one or more times per year. EFRI will sample Tailings Impoundment 3 on a quarterly
frequency in 2018. 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 September 13, 2018.
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 at 435-678-4128.
Yours very truly,
