Re: Energy Fuels Resources (USA) Inc. Notification for the Fourth Quarter of 2014 -
Schedule for the NESHAPs Radon Flux Measurements for Tailings Impoundment 3 at
the White Mesa Mill
Dear Mr. Bird:
Energy Fuels Resources (USA) Inc. ("EFRI") plans to perform a fourth quarter sampling event
for NESHAPs Radon Flux measurements for Tailings Impoundment 3 at the White Mesa Mill.
As indicated in letters dated December 4, 2013, March 6, 2014, and August 7, 2014 the first
quarter measurements were taken March 24-27, 2014, the second quarter measurements were
taken June 2-5, 2014, and the third quarter measurements were taken September 8-11, 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 fourth quarter sampling event for Tailings Impoundment 3 in 2014.
Sampling Dates Tailings Impoundment 3
October 13-16, 2014 Fourth Quarter Sampling Event
Tellco Environmental of Grand Junction, Colorado ("Tellco") will perform approximately 100
measurements on the beach and cover area of Tailings Impoundment 3 during the fourth quarter
sampling event. These measurements will be performed in accordance with methods and
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 fourth quarter
sampling event for Tailings Impoundment 3 is expected to conclude on October 16, 2014.
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
lietfer to B. Bird
