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. On March 6, 2019 EFRI rescheduled the sampling event to March 25 — 28, 2019 due to
inclement weather.
On March 21, 2019 EFRI submitted a cancellation notice for the Tailings Impoundment 3
sampling rescheduled for March 25 — 28, 2019. EFRI noted that due to the continuation of
inclement weather and the resultant standing water and mud EFRI could not complete the
sampling event in the first quarter of 2019.
The sampling event has been rescheduled to April 22, - 25, 2019.
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 both the February 12, and March 6, 2019 letters EFRI stated that
Tailings Impoundment 3 would be sampled on a quarterly frequency in 2019. 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, _
