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 February 12, 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
first quarter of 2019 at Tailings Impoundment 3 at the White Mesa Mill from March 18 - 21, 2019.
However, due to inclement weather, EFRI is rescheduling the sampling event. This letter serves
as notification that the first quarter 2019 NESHAPs Radon Flux sampling event for Tailings
Impoundment 3 is being rescheduled from March 18 - 21, 2019 to March 25 — 28, 2019.
As stated in the February 12, 2019 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 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 March 28, 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. David
Turk, Environmental Health and Safety Manager, at 435-678-4113.
