Re: Transmittal of Source Assessment Report for MW-11 and MW-24, White Mesa Mill
Groundwater Discharge Permit UGW370004
Dear Mr. Howard:
Enclosed are two copies of Energy Fuels Resource (USA) Inc.'s ("EFRI's") Source Assessment Report
("SAR") for manganese in MW-11 and fluoride, field pH, cadmium, beryllium, nickel, and thallium in MW-24,
at the White Mesa Mill.
Field pH, cadmium and thallium exceeded the GWCLs in the third quarter 2018 as described in the Q3 2018
Exceedance Notice dated November 14, 2018. As required by Part I.G.4(d) of the GWDP, EFRI submitted a
Plan and Time Schedule ("Q3 2018 Plan and Time Schedule") on December 5, 2018 for the assessment of MW-
24 for the third quarter of 2018, which covers the constituents that were identified as exceeding the GWCLs.
EFRI has included beryllium, fluoride, and nickel for MW-24 as part of this SAR due to increasing trends in
concentrations and out-of-compliance status for these constituents since the time the Plan and Time Schedule
was submitted on December 5, 2018. DWMRC approved the Q3 2018 Plan and Time Schedule on March 5,
2019.
Manganese in MW-11 exceeded the GWCLs in the fourth quarter of 2018 as described in the Q4 2018
Exceedance Notice dated January 24, 2019. As required by Part I.G.4(d) of the GWDP, EFRI submitted a Plan
and Time Schedule ("Q4 2018 Plan and Time Schedule") on February 21, 2019 for the assessment of MW-11
for the fourth quarter of 2018, which covers the constituent that was identified as exceeding the GWCL.
DWMRC approved the Q4 2018 Plan and Time Schedule on March 5, 2019.
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,
