HERBERT Governor SPENCER J COX Lieutenant Governor September 15, 2014 Department of Environmental Quality Amanda Smith Executive Director DIVISION OF RADIATION CONTROL Rusty Lundberg Director DRC-2014-005383 Kathy Weinel, Quality Assurance Manager Energy Fuels Resources (USA) Inc. 225 Union Blvd. Suite 600 Lakewood, CO 80228 Subject: Energy Fuels Resources (USA) Inc. 2n Quarter 2014 Groundwater Monitoring Report, Groundwater Quality Discharge Permit No. UGW3 70004 Dear Ms. Weinel: The Utah Division of Radiation Control (DRC) has reviewed: 1. The Energy Fuels Resources (USA) Inc. ("EFR") August 15, 2014 Td Quarter 2014(April through June) Groundwater Monitoring Report Groundwater Quality Discharge Permit UGW370004 White Mesa Uranium Mill; 2. The EFR August 11, 2014 State of Utah Ground Water Discharge Permit No. UGW370004 White Mesa Uranium Mill ("GWDP") - Notice Pursuant to Part I.G.I (a); and, 3. The EFR August 11, 2014 State of Utah Ground Water Discharge Permit No. UGW370004 White Mesa Uranium Mill - Removal of Certain Groundwater Monitoring Parameters from Accelerated Monitoring Status. A summary of findings is below: EFR August 11, 2014 Request to Return Monitoring Well MW-28 Manganese, MW-29 Manganese, and MW-25 Fluoride to Baseline Monitoring Frequency: Per the EFR August 11, 2014 Request, EFR provides information regarding compliance monitoring at wells MW-28 for manganese, MW-29 for manganese, and well MW-25 for fluoride. These wells/parameters are currently required to be sampled on an accelerated basis due to out-of-compliance status. MW-28 Manganese The August 11, 2014 request for monitoring frequency reduction for manganese in MW-28 states that monitoring results "have been below the Groundwater Compliance Limit ("GWCL ") specified in the GWDP for eight consecutive sampling events since Q2 2012." Per DRC review of the request and past sampling result it appears that the last eight consecutive accelerated samples for manganese in monitoring well MW-28 have been below the GWCL. Based on past approvals of return to baseline monitoring, this request is consistent and return to baseline monitoring is appropriate. MW-29 Manganese The EFR August 11, 2014 request for monitoring frequency reduction for manganese in MW-29 is based on the eight most recent consecutive monitoring results showing concentrations below the GWCL.

MW-25 Fluoride The EFR August 11,2014 request for monitoring frequency reduction for fluoride in MW-25 is based on the eight most recent consecutive monitoring results showing concentrations below the GWCL. Per DRC review of the monitoring results it appears that return to baseline monitoring frequency is appropriate. Therefore, the wells/parameters listed on the table below are approved to be returned to the baseline monitoring frequency: MW-28 Manganese Semi-Annual MW-29 Manganese Semi-Annual MW-25 1 Fluoride | Quarterly EFR 2nd Quarter 2014 Groundwater Monitoring Report: DRC reviewed the following items regarding the EFR 2nd Quarter 2014 Groundwater Monitoring Report: 1. Accelerated Monitoring (wells and parameters), 2. Field Sample Collection Sheets (well purging and field parameter collection), 3. Blind Duplicate Analysis (Relative Percentage Difference), 4. Analytical Laboratory Certification, 5. Laboratory Report Turn Around Times, 6. Sample Holding Times, 7. Sample Preservation, 8. Analytic Reporting Limits, 9. Laboratory Quality Assurance and Quality Control Reports and Flags, 10. Time Concentration Plots of Data, 11. Depth to Groundwater Measurements, 12. Water Table Contour Maps (Burro Canyon Aquifer), 13. Relative dewatering of the groundwater mound around the wildlife ponds, 14. Laboratory data and comparison with the Permit Ground Water Compliance Limits. The review was conducted with consideration of a May 25, 2012 EFR Permit modification request which was made in order to document accelerated reporting and monitoring agreements made during a teleconference with the Utah Division of Radiation Control (DRC). Per DRC staff discussions with EFR the May 25, 2012 request will be included with the White Mesa Mill Ground Water Permit Renewal. DRC review of the 2nd Quarter 2014 Report recognizes the telephone agreement regarding the timeline for EFR to submit updated compliance notice and initiate accelerated monitoring. DRC notes that monitoring well MW-28 was damaged prior to groundwater sampling, and that exceedances of cadmium, uranium and vanadium GWCL's in that well during the 2" quarter 2014 may be the result of contamination after the damage. Based on the findings above it appears that the 2nd Quarter 2014 Groundwater Report complies with the Permit requirements; therefore, the review is hereby closed out.
