Re: Energy Fuels Resources (USA) Inc. Notification for the Third Quarter of 2014 -

the White Mesa Mill
Dear Mr. Bird:
Energy Fuels Resources (USA) Inc. ("EFRI") plans to perform a third sampling event for
NESHAPs Radon Flux measurements for Tailings Impoundment 3 at the White Mesa Mill. As
indicated in letters dated December 4, 2013 and March 6, 2014, the first measurements were
taken March 24-27, 2014 and the second measurements were taken June 2-5, 2014. Per 40 CFR
61.253, EFRI is permitted to monitor Radon Flux one or more times per year. EFRI is choosing
to sample Tailings Impoundment 3 quarterly in 2014 to capture a wider range of climatic
conditions.
Consistent with 40 CFR 61.253, EFRI is permitted to submit a schedule for additional sampling
periods either prior to or after the first measurement period. Therefore, EFRI is providing this
schedule for the third sampling event for Tailings Impoundment 3 in 2014.

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 third sampling
event for Tailings Impoundment 3 is expected to conclude on September 11, 2014.
EFRI will provide safety and radiological orientation for any Utah Department of Air Quality
