HomeMy WebLinkAboutDRC-2018-000968 - 0901a068807aaa42-Z0l8 -0008 Sampling Report This is a review of the 2017 Annual Tailings Cells Wastewater Sampling Report dated November 16, 2017 (“Report”) for the Energy Fuels Resources (USA), Inc. (“EFR”) White Mesa Uranium Mill, near Blanding, Utah (“Mill”). For the review of the 2017 Report the following enforcement documents were 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. • Utah Department of Environmental Quality Division of Radiation Control Guidance for Groundwater Split Sample Collection at Uranium Mill Operations, August 7, 2007. • Tailings and slimes Drain Sampling Program (hereafter “Plan”) Revision 2.1 dated July 30, 2012. Summary of Compliance EFR informed the Utah Division of Waste Management and Radiation Control (“Division”) in a letter dated July 11, 2017, that EFR would be sampling the tailings cell wastewater on August 22 and 23, 2017. Because of Division staff had scheduling conflicts the tailings cell wastewater sampling event occurred on August 29, 2017. The letter from EFR provided notice prior to sampling as required in Part I.E. 10(d)(6) of the Permit. Part LET 0(d) of the Permit requires EFR to sample annually the tailings cells wastewater in August of each year; therefore, the August 29, 2017 sampling date meets this requirement.

The Report was received by DWMRC on November 20, 2017, which meets the Plan requirement. EFR collected tailings cell wastewater samples from Tailings Cells 1, 3, 4A, and 4B, and Tailings Cell 2 Slimes Drain (see photograph in attachment 2), and Tailings Cells 4B and 4B Leak Detection Systems (“EDS”). The EDS for Tailings Cells 1, 2, and 3 were dry and not sampled. DWMRC staff Dean Henderson collected a split sample of Tailings Cell 4B and also witnessed EFR staff sample all the other wastewater sample locations. EFR sampled all available tailing cell wastewater sample locations as required in Part I.E.10 of the Permit. The following meet the requirements in Part I.E.10 of the Permit: • Approved analytical methods. • Parameter holding times. • Laboratory receipt Parameter Temperature. • Certified Laboratory. • Analyzed for parameters required in Part I.E. 10(d)(1) of Permit. • Collected duplicate sample. The Report met all of the following reporting requirements in Section 6 of the Plan: 1) Description of sampling methodology, equipment and decontamination procedures identify all quality assurance samples, e g trip blanks, equipment, blanks, and duplicate samples. 2) Analytical data interpretation for each tailing cell, slimes drain, and leak detection system sample. 3) Written summary and conclusions of analytical results, 4) Table summarizing historic analytical results, 5) QA evaluation. 6) All field data sheets accompanying the sampling event. 7) Copies of the laboratory reports. 8) Tailings and Slime Drains System Sample Locations Map. Duplicate Sample Comparison Comparisons of duplicate samples analytical results are summarized in Table 7 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). For radiologic duplicate sample a relative error ratio is calculated (“RER”). A RER <2 is acceptable (DRC 2007). EFR Duplicate Sample Comparison The RPD comparisons between the EFR analytical results for Tailing Cell 4A and its duplicate sample “Cell 65” were below 20% with the exception of acetone (27%) and Ammonia (41%). The RER for gross alpha was 20.5 exceeding the acceptable RER of 2 (see Table 7 below). Page 3 Because the remainder analytical results comparisons between the two samples had RPD <20%, DWMRC staff feels these RPD exceedances are not a concern and the analytical results between the two samples are comparable. DWMRC Duplicate Sample Comparison The DWMRC collected a duplicate sample of Tailings Cell 4B with EFR. The DWMRC also collected a duplicate of this location and identified it as “Cell 6”. The RPD comparisons between the DWMRC for metals analytical results for Tailing Cell 4B and its duplicate sample Cell 6 were above 20% with the exception of iron and mercury. Because the remainder analytical results comparisons between the two samples had RPD <20% exception of chloromethane (87%), DWMRC staff feels these RPD exceedances are not a concern and the analytical results between the two samples are comparable (see Table 7 below). DWMRC Sample Comparison to EFR The RPD comparison between the analytical results found on Table 7 for the DWMRC Cell 4B and Cell 6 sample to EFR Cell 4B sample. In comparing the DWMRC Cell 4B sample to EFR Cell 4B sample all analytical results were below 30% with the exception of ammonia (145%), acetone (33%), chloromethane (35%), and chloride (30.3%). In comparing the DWMRC Cell 6 sample to EFR Cell 4B sample 11 out of the 19 metals analyzed had RPD greater than 30%. The remainder analytical results comparisons between the two samples had RPD <20% exception of ammonia (136%) and chloromethane (114%). It appears that the DWMRC Cell 4B sample is the most comparable to the EFR Cell 4B sample. The purpose for annual monitoring of the tailings cells wastewater at the Mill is to inventory their contaminants and concentrations. This annual 2017 monitoring event for the tailing cells wastewater has accomplished this purpose. Additional Samples for Radiologies, Viscosity, and Specific Gravity Although not required in the QAP, Permit, or Plan EFR conducted voluntary analyses on the wastewater on August 29, 2017 and provided this information in the Report. Samples were analyzed for radium-226, thorium-228, thorium-230, thorium-232, uranium 233/234, uranium 235/236, uranium-238, and specific gravity (data summarized in Table 9 below). This analytical data of the wastewater are for informational purposes only. 2017 Mill Operations Impact on the Wastewater in Tailings Cells The analytical results for the 2017 Tailings Cells Wastewater Monitoring Event are summarized in tables 1 through 8 in Attachment 1 below. Figure showing a photograph of sampling event are shown in Attachment 2. Based on the tailings cells wastewater sampling analytical results all concentrations for the 2017 tailing cell wastewater monitoring event appear to have relatively similar concentrations to historic monitoring events with the exception of tailing Cell 3. EFR staff commented that a few months prior to sampling Cell 3 that it was almost dry and because of recent rain storms at the Mill storm water had appeared have collected in the cell. The 2017 Cell 3 analytical results show that concentrations are in many cases are orders of magnitude lower than its historic concentrations. Therefore, it appears that the recent storm water may have collected and influenced the analytical results in Cell 3. Page 4 Other than Cell 3, the addition of wastewater to the tailings cells in 2017 appears not have impacted historic wastewater concentrations in the tailing cells. Conclusion on Report Based on D WMRC staff observation of EFR staff performing the sampling and monitoring on August 29, 2017 and after the DWMRC review of the Report, it appears that EFR appropriately followed the requirements in the Permit, QAP and Plan and no further action is required of EFR.
