Re: Energy Fuels Resources (USA) Inc. Notification of Rescheduling for the Radon Flux
Measurements for Tailings Impoundment 2 at the White Mesa Mill
Dear Mr. Goble:
On March 2, 2020 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 2 at the White Mesa Mill from April 6 — April 9, 2020.
On March 26, 2020 EFRI submitted a cancellation notice for the Tailings Impoundment 2 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 noted in the previous letters, pursuant to the letter from the Utah Division of Waste Management and
Radiation Control ("DWMRC") dated, July 23, 2014, EFRI is required to measure radon flux at Tailings
Impoundment 2 ("Cell 2") at the White Mesa Mill (the "Mill") semi-annually in accordance with 40 CFR
61, Appendix B, Method 115. The measured results are included in the Semi-Annual Effluent Reports for
that reporting period.
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,
ENERGY FUELS RESOURCES (USA) INC.
