Re: Energy Fuels Resources (USA) Inc. Postponement of NESHAPs Radon Flux
Measurements for Tailings Impoundment 3 at the White Mesa Mill
Dear Mr. Bird:
On March 2, 2020, Energy Fuels Resources (USA) Inc. ("EFRI") submitted a 30-day notice
regarding a radon flux sampling event for Tailings Impoundment 3 ("Cell 3") at the White Mesa
Mill (the "Mill") that was scheduled to be conducted from April 6 - 9, 2020. However, due to the
public health concerns associated with COVID-19 and social distancing suggestions, EFRI is
postponing the sampling event until further notice. The sampling event will be scheduled as
soon as possible, when it is safe to do so.
Per 40 CFR 61.253, EFRI is permitted to monitor Radon Flux one or more times per year. In the
March 2, 2020 letter, EFRI stated that Tailings Impoundment 3 would be sampled on a semi-
annual frequency in 2020. EFRI will strive to meet this schedule, and will monitor the health
recommendations and reschedule the event based on those recommendations.
EFRI will provide notice upon rescheduling of the Tailings Impoundment 3 event.
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 truly,
cff
