Re: Transmittal of Source Assessment Report for MW-18 and MW-24, White Mesa Mill
Groundwater Discharge Permit UGW370004
Dear Mr. Anderson:
Enclosed are two copies of Energy Fuels Resource (USA) Inc.’s (“EFRI’s”) Source Assessment Report
(“SAR”) for sulfate in MW-18 and fluoride, field pH, cadmium and thallium in MW-24, at the White Mesa
Mill. Sulfate in MW-18 and field pH and fluoride and field pH in MW-24 exceeded their Groundwater
Compliance Limits (“GWCLs”) in the third and fourth quarter of 2015. On February 11, 2016, EFRI submitted
a notice (“4th Quarter 2015 Exceedance Notice”) to the Director under Part I.G.l (a) of the Groundwater
Discharge Permit (“GWDP”) providing notice that the concentrations of specific constituents in the monitoring
wells at the Mill exceeded their respective GWCLs. As required by Part I.G.4(d) of the GWDP, EFRI submitted
a Plan and Time Schedule (“Q4 2015 Plan and Time Schedule”) for the assessment of MW-18 and MW-24 for
the fourth quarter of 2015, which covers the constituents that were identified as exceeding the GWCLs. EFRI is
voluntarily adding cadmium and thallium in MW-24, which were not included in the Q4 2015 Plan and Time
Schedule. The Q4 2015 Plan and Time Schedule was submitted on March 3, 2016, and was approved by the
DWMRC in correspondence dated March 30, 2016. This transmittal also includes two CDs each containing a
word searchable electronic copy of the report.
If you should have any questions regarding this report please contact me.
Yours very truly.
