White Mesa Uranium Mill, near Blanding, Utah On November 20, 2013 the Division of Radiation Control ("DRC") received the 2013 Annual Seep and Springs Sampling Report ("Report") [eDocs: DRC-2013-003540] for the Energy Fuels Resources (USA), Inc. ("EFR") White Mesa Uranium Mill ("Mill"), near Blanding, Utah. For the review of this Report the following regulatory enforcement documents will be used: • White Mesa Uranium Mill Ground Water Quality Assurance Plan ("QAP"). Revision 7.2, dated June 6, 2012. • Groundwater Discharge Permit No. UGW370004 ("Permit"). Permit version that was signed on August 24,2012. • Sampling Plan for Seeps and Springs In the Vicinity of the White Mesa Uranium Mill. Revision 0. ("Plan"). • Utah Department of Environmental Quality Division of Radiation Control Guidance for Groundwater Split Sample Collection at Uranium Mill Operations. August 7, 2007. Summary of Compliance EFR informed the DRC in a letter dated June 10, 2013, that EFR would be sampling the seeps and springs on July 16, 2013 (eDocs: DRC-2013-002721). Therefore EFR provided a 15 day notice prior to sampling as required in Section 3 of the Plan. The Plan requires the Report to be submitted to the DRC on or before December 1 of each year. The Report was received by the DRC on November 20, 2013, which met the Plan requirement. 195 North 1950 West • Salt Lake City, UT Mailing Address P O Box 144850 • Salt Lake City, UT 84114-4850 Telephone (801) 536-4250 • Fax (801-533-4097 • T D D (801) 536^414 www deq utah gov Printed on 100% recycled paper Page 2 The Report met all of the following reporting requirements in Section 6 of the Plan: 1) Document the sampling event by means of providing the field sheets recorded at the time of sampling. 2) Copies of all field measurements and laboratory results. 3) Provide a water table contour map that includes a water table elevation of all groundwater monitoring wells at the facility (3rd quarter 2013 water level measurements) and the elevations of the phreatic surface observed at each of the seep and springs sampled. 4) Provide an evaluation and interpretation of the groundwater quality data collected. The DRC staff also observed the EFR staff sample Cottonwood, Entrance and Ruin Springs (see photographs in Figures 1-3). Westwater Seep had a seepage face, but had no standing water so therefore no sample could be collected. Coral Canyon and Corral seeps were found to be dry and therefore no sample could be collected. DRC staff observed the EFR staff perform the sampling and monitoring on July 16, 2013 and after the DRC review of the Report, it appears that EFR appropriately followed the QAP and Plan. Duplicate Sample Comparison Comparisons of duplicate samples analytical results are summarized in Table 6 in Attachment 1 below. To determine if samples results between two samples from the same laboratory are comparable a relative percent difference ("RPD") of 20% is acceptable (DRC 2007). To determine if samples results between two samples from two different laboratories are comparable a RPD of 30% is acceptable (DRC 2007). The DRC collected a duplicate sample of Ruin Spring with EFR. The DRC collected a duplicate of this spring and identified it as "Spring 1". The RPD comparisons between the analytical results were below 20% and therefore comparable. EFR collected a duplicate of Ruin Spring and identified it as "Back Spring". The RPD comparisons between the analytical results were below 20% and therefore comparable. The RPD comparison between the analytical results found on Table 6 for the DRC Ruin Spring sample and EFR Ruin Spring sample were below 30% and therefore comparable. Mill Operations Impact on the Seeps and Springs. The analytical results for the 2013 seeps and springs monitoring event are summarized in tables 1 through 5 in Attachment 1 below. As stated above Westwater Seep, Coral Canyon and Corral seeps were found to ether dry or not enough moisture to collect a water sample. Cottonwood Spring No VOCs or radiologics were detected. The only metal detected was uranium and it did not exceed its GWCL. Major ions were detected. A comparison of the 2009, 2010, 2011, and 2012 data to the 2013 data shows that the concentrations of most detected analytes remained approximately the same. Overall, the data reported for Cottonwood Spring appear to show no indication of Mill influence. Page 3 Entrance Spring No VOCs were detected. Major ions were detected. Gross alpha was detected but did not exceed its GWCL. The only metals detected were iron, manganese, selenium, and uranium. Only uranium (38.8ug/L) exceeded the site used GWCL (30ug/L). In addition, pH (6.41) exceeded the GWCL pH Standard (6.5-8.5). This is the first time that both uranium and pH or any other contaminants have exceeded a GWCL at Entrance Spring since EFR was required to annually sample the seeps and springs starting in 2009. In addition, of the 17 contaminants that had detectible concentrations 13 (including uranium and pH) were historic high concentrations. These historic high concentrations and uranium and pH exceedance may be due to: 1) The Blanding area received heavy precipitation within 24 hours of the sampling event which caused surface water to briefly flow throw the drainage area for Entrance Spring. This surface water may have contributed to the historic high concentrations and; 2) Because of recent drought conditions in the Blanding area over the last few years the sampling location for the first 3 sampling events (2009, 2010, and 2011) that had standing spring water was now dry. Therefore the 2012 and 2013 spring sample locations were moved approximately 30 feet down gradient of the spring drainage to a marsh area saturated with the spring water. This area had very little standing water therefore it was necessary to excavated a hole with a hand shovel to allow the spring water to accumulate in the hole with enough water for samples to be collected (see Figure 1). These marsh conditions may have also have contributed to the historic high concentrations. To determine if Entrance Spring is showing indications of being impacted by the Mill, DRC will collect a split sample with EFR in the 2014 annual seeps and springs sampling event at that location. Should the data show that uranium and/or pH concentrations continue to exceed GWCL DRC may require an increase in sampling frequency or other actions required by the DRC Director to determine possible impact the Mill may have on Entrance Spring. Ruin Spring No VOCs or radiologics were detected. The only metals detected were selenium, silver and uranium. None exceeded GWCL. Major ions were detected. A comparison of the 2009, 2010, 2011, and 2012 data to the 2013 data shows that the concentrations of most detected analytes remained approximately the same. Overall, the data reported for Ruin Spring appear to indicate no indication of Mill influence. Conclusion on Report Based on the review of the Report requirements appear to satisfied the Permit, QAP, and Plan requirements and no further action is required of EFR.
