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 March 2, 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 half of
2020 at Tailings Impoundment 3 at the White Mesa Mill from April 6 — April 9, 2020.
On March 26, 2020 EFRI submitted a cancellation notice for the Tailings Impoundment 3
sampling scheduled for April 6 — April 9, 2020 due to public health concerns associated with
COVID-19.
The semi-annual sampling event has been rescheduled to April 28, - 30, 2020. Due to scheduling
issues associated with delays caused by COVID-19 EFRI is unable to provide a 30-day notice for
this rescheduled sampling event.
As stated in the previous letters, 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. However, since the first quarter
sampling has been cancelled due to weather conditions beyond our control, EFRI will change the
planned 2019 sampling frequency on Tailings Impoundment 3 to three times in 2019, with one
sampling event in each 4-month period in 2019 (January — April, May through August, and
September through December).
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 truly,
