("EFRI") currently operates the White Mesa Uranium Mill ("Mill") under the Utah Department of Environmental Quality Radioactive Materials License ("RML") Number UT1900479 Amendment #08. The White Mesa Mill Tailings Management System, Revision 2.5, dated March 2017, (which is section 3.1 of the Mill's Environmental Protection Manual) provides the methodologies for monitoring and evaluating the Tailings Management System. Reference documents are listed in the Reference section at the end of this summary. This Annual Technical Evaluation Report ("ATER") satisfies the requirements in RML Condition 12.3 for preparation of an ATER. This Annual Technical Evaluation was performed on November 11th through November 18th, 2019, in accordance with the White Mesa Mill Environmental Protection Manual and consisted of the following elements: • Review of the Tailings Management System operation and maintenance procedures and interviews with current site personnel and management to ensure there is an adequate understanding of the requirements. • Review of randomly selected daily, weekly, monthly, and quarterly inspection reports to ensure established procedures are followed and that there are no irregularities that have not been properly documented. • Interview responsible personnel to verify that updated training has been given. • Discuss with inspection personnel, as necessary, any non-routine or abnormal occurrences noted during the review of the inspection reports. Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 19, 2019 • Inspection of the tailings embankments and appurtenances for signs of distress or concern that could potentially affect the structural integrity of the Cell dikes and containment. • Inspection of the area surrounding the tailings facility to determine condition of diversion ditches. Review of additional peripheral items, such as prairie dog activity, which could affect the system. • Review of the survey conducted on Movement Monitors along the boundary dikes, and comparison of the data to recent surveys. • Review of the tailings slurry and raffinate piping systems to ensure that their operation does not have the potential to affect the integrity of the tailings dikes or liner system. • Review of maintenance activities in the tailings area that have the potential to affect the integrity of the tailings dikes or liner system. • Photographic documentation of the condition of the Cell dikes and surrounding areas. • Review recommendations provided in previous technical evaluation reports and document the implementation or continued need for action. 2.0 OPERA TIO NS During the period covered by this evaluation, November 2018 through October 2019, the mill processed several alternate feeds as well as recycling pond solutions through the mill for recovery of uranium and vanadium. The mill processed 770 tons of Sequoyah Fuels Corp "Sequoyah" and 8.8 tons of Resin Beads. Roughly 254 million gallons of tailings solution was reprocessed through the Page4 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 19, 2019 mill. During Mill operations various solutions and solids were discharged to the Mill tailings management system. The solids were discharged to Cell 4A. Cell 1-I ( currently referred to as Cell 1) and Cell 4B were maintained as evaporation cells, and only raffinate solution from the solvent extraction circuit and process water were discharged to Cell 1 and Cell 4B. In efforts to maintain freeboard limits, solutions were also transferred between cells. 3.0 SITE MANAGEMENT Mr. Logan Shumway is the current White Mesa Mill Manager. Mr. Shumway has the overall responsibility to ensure that the Tailings Management System is operated and maintained in accordance with State of Utah Radioactive Material License No. UT1900479. Mr. Terry Slade is the Radiation Safety Officer ("RSO"). Among Mr. Slade's responsibilities in his current role is the oversight of day-to-day monitoring and inspecting of the Tailings Management System. Inspections of the Tailings Management System were performed by trained Mill personnel. Under Mr. Slade the trained inspectors are: • Tanner Holliday • Garrin Palmer • Deen Lyman The inspectors are all from the Environmental and Safety Department at the White Mesa Mill. Each inspector has documentation of recent training on the inspection procedures. 4.0RECORDS The mill maintains daily, weekly, monthly, and quarterly inspections for the tailings area. Copies of the daily and weekly inspection reports for the month of February 2019 are included as a part of this evaluation. Also, copies of all the monthly inspections and quarterly reports are included as part of this evaluation. A review of these records was conducted to confirm use of the correct forms, verify completeness, evaluate content, and to evaluate any unusual events. The Environmental department Page 5 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 19, 2019 appears to be keeping an attentive watch over the tailings area. All records reviewed are in order and are consistent with the requirements in the Environmental Protection Manual. 5.0 DIVERSION CHANNELS To the north of the Mill tailings cells there are three diversion channels, which prevent runoff from flowing into the tailings cells and Mill yard area. Conditions at the time of review are dry with no water present. All channels have been maintained during the year and have minimal vegetation. There was no significant erosion on any of the channels. The South side of the #1 Channel is a constructed berm varying in height from O to 4 feet. The berm is in good condition with growing vegetation. There were no significant erosion concerns. Locations of the diversion ditches are shown in the Mill Site Drainage Basins drawing located in the Site Photographs section of this document. Photos of the current status of the diversion ditches are included in the Site Photographs section of this document. At the current time there are no concerns with functionality or structural stability of the berms and channels. 6.0 TAILINGS DISPOSAL CELLS 6.1 CeJJ l(a.k.a, Cell 1-P Cell 1 was the second cell placed into service after being completed in 1981. The Cell was designed as an evaporation cell for solutions only. No solids are placed into Cell 1. The solution discharged to the Cell normally comes from the solvent extraction circuit, but solution is periodically pumped back and forth between Cell 4A, Cell 4B, and Cell 1 to maintain required freeboard limits in the entire system. Solution freeboard limits for all of the tailings cells are established in Section 3.0 to Appendix D of the approved license application and confirmed as License Condition 10.3 of the current license. The established maximum freeboard limit for Cell 1 is 5615.4 feet above mean sea level ("MSL''). Solution levels did not exceed the maximum freeboard limit during the period evaluated. Page 6 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 19, 2019 Cell 1 has a soil cover over the upper portion of the synthetic liner. The soil serves to cover and protect the liner from UV coming from direct sunlight. The soil cover is in good condition. The south side of Cell 1 originally shared a dike with Cell 2. Cell 2 has since been filled and Phase 1 cover activities were started in April 2016 and were completed in May 2017. The roadways around the cell are well maintained. It was found that there is some prairie dog activity on the North side of Cell 1 in proximity to the edge of the cell. Interviews with the Mill Environmental Department found that they actively monitor and control the activity around the tailings ponds. It was also found that there was an area where the soil cover over the pond liner had a couple of erosion channels develop. It is recommended that these channels be repaired. Photos of the current status of Cell 1 are included in the Site Photographs section of this document. 6.2 Cell 2 Cell 2 was the initial tailings cell constructed and was placed into service when the Mill first began processing ore in 1980. It is no longer receiving any discharge from the mill and has been deemed full. The surface of Cell 2 has previously been covered with a random fill (platform fill) over the sands to prevent blowing sands as well as reduce radon emissions. Over the years this has been added to and adjusted to reduce radon emissions. In 2016 a revised final cover design was proposed for the tailings cells. Reference "Cell 2 Reclamation Cover Design, Implementation, and Performance Assessment Plan" by MWH. Starting in April 2016 construction was started to put in place the first phase of the cover design. This work has been completed. In addition, a test section of the full cover design was constructed in the South- East corner of Cell 2. This section has instrumentation and equipment to evaluate the performance of the cover design and will be monitored over the coming years. The test section is officially in a calibration period. Data collection has started and will be evaluated for long-term comparison. In order to monitor the consolidation of the tailings sands contained within Cell 2, elevation readings on settlement monitors are taken monthly. A summary of the settlement monitor elevations is included with this report along with graphs of the settlement data. Section 7 of this ATER provides Page 7 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 19, 2019 an evaluation of the settlement monitoring results. Photos of the current status of Cell 2 are included in the Site Photographs section of this document. 6.3 Cell 3 Cell 3 was constructed and placed into service in 1983. It is currently used only for disposal of l l(e).2 waste materials from in-situ uranium producers and for Mill solid waste and trash. During the evaluation period, no tailings solutions or sands were placed in the cell. Approximately 85% of Cell 3 has been covered with random fill. The exposed sands within the cell have been pushed out and graded. The mill utility crew has continued to place interim cover over the sands as stability has permitted. The center section of Cell 3 is marked with signs showing areas designated for 1 le.2 disposal and mill waste disposal. There is regular activity in these areas. Sparse vegetation growth is established on the East end of the cell where interim cover has been placed. The west end has a portion of the phase 1 soil cover placed. The Cell 3 Spillway is in good condition. It was found that there are some blown sands accumulated in the area around the spillway. It is recommended that the sands be cleaned from the roadway. Section 3 .1 of the Environmental Protection Manual establishes the free board limits for the tailings cells. Cell 2, Cell 3, and Cell 4A do not require freeboard limits as Cell 4B is the final downstream tailings cell. Solution levels were not taken in Cell 3. The south dike of Cell 3 is shared with Cell 4A and Cell 4B. The dike crest and all roadways around the cell are well maintained. Photos of the current status of Cell 3 are included in the Site Photographs section of this document. In order to monitor the consolidation of the tailings sands contained within Cell 3 elevation readings on settlement monitors are taken monthly. The trending of these readings will be used to determine when acceptable consolidation of the tailings sands has occurred. A summary of the settlement monitor elevations is included with this report along with graphs of the settlement data. Section 7 Page 8 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 19, 2019 provides an evaluation of the data collected. 6.4 Cell 4A Cell 4A was originally constructed in 1989 and placed into service in 1990. Cell 4A was never used for disposal of tailings material other than process solutions during the first years of its operation. Cell 4A fell into disrepair and was removed from service in the early 1990' s after a brief period of use. The original 40-mil high-density polyethylene ("HDPE") liner was removed from the Cell as well as all contaminated materials and soil. The Cell was relined with a new HDPE lining system beginning in the fall of 2007 and finishing in the summer of 2008. The Cell was placed into service in October of 2008. The Cell 4A dikes provide containment for current tailings disposal at the White Mesa Mill site. The east and south dike are covered with minor vegetation with no significant erosion. The west dike is shared with Cell 4B. The top surface and roadways on the dikes are all well maintained. Cell 4A is the current cell for disposal of solid tailings from mill processing. Sands have been placed along the northwest side with exposed sands on roughly 30% of the Cell 4A surface. Solutions fill the remaining capacity. The mill has been processing the pond solutions to recover uranium and vanadium contained in the solution. In doing so the solutions from Cell 1, Cell 4A, and Cell 4B have been pumped to the mill as well as transferred between cells. The spillway is in good condition. There are a clutter of pipes in the spillway that are used for transferring solutions between Cell 4A and Cell 4B. It is recommended that the existing piping be reviewed and any unnecessary pipes be removed from the spillway. Photos of the current status of Cell 4A are included in the Site Photographs section of this document. Section 3 .1 of the Environmental Protection Manual establishes the free board limits for the tailings cells. The previous freeboard limit of 5,593.74 for Cell 4A is set out in a letter from the Director dated November 20, 2008. The Director granted a variance from the Cell 4A freeboard limit on January 13, 2011 and approved the removal of the Cell 4A limit and the use of Cell 4B on January Page 9 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 19, 2019 27, 2011. The weekly measurements are no longer required for compliance with freeboard limits, but are required for the calculation of the daily allowable volume of fluids pumped from the Cell 4A LDS. The freeboard elevation data and charts included in the document reflect the changing levels within Cell 4A and 4B. 6.5 Cell 4B Cell 4B was constructed in 2010 and approved for service in 2011. It is currently used only for solution containment. The cell is lined with the same HDPE system as is installed in Cell 4A. This cell currently serves as the final collection point for tailings solutions. Photos of the current status of Cell 4B are included in the Site Photographs section of this document. The southern dike is the final containment for mill tailings. The south slope has been recently maintained and there is very little vegetation and no erosion present. The top surface and roadways on the dikes are all well maintained. Section 3.1 of the Environmental Protection Manual establishes the freeboard limits for the tailings cells. Cell 2, Cell 3, and Cell 4A do not require freeboard limits as Cell 4B is the final downstream tailings cell. Cell 4B is set at 5,594.6 FMSL. A review of the records found that there were no instances of the solution level in Cell 4B exceeding the freeboard limit during the evaluation period. 6.6 Movement Monuments The Movement Monuments are placed along the outside boundary dikes in the mill tailings area. The intent is to survey these monuments yearly and monitor for any movement in the dike. The current boundary consists of the South Cell 4A dike and the South Cell 4B dike. The current year's survey was conducted in August and data has been provided in a report by Cory Smith of Jones & DeMille Engineering Inc, who is a Utah-Certified Land Surveyor. Review of the survey data in comparison to survey from previous years found that there were some inconsistencies in the survey locations of some of the monitors. In October a second survey of the monuments that were out of specification found the previous survey to be inaccurate and all monitors are within specification of Page 10 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 19, 2019 previous surveys. 7 .0 Settlement Monitors Settlement monitors are required to be placed on covered tailings cells. Cell 2 has a series of monitors covering the cell. Cell 3 also has monitors located where cover has been placed over filled areas. The locations of the monitors are shown on the Settlement Monitor Points drawing included with the monitoring data. The tracking of the changing elevations of the monitors shows the settlement or stability of the tailings within the cell. Elevation surveys of all settlement monitors are taken monthly. The trend of the data from these monuments shows the settling or stability of the tailings sands with the exception of monitor Cell 4A Toe. The Cell 4A Toe monitor does not show any movement or instability at the base of the southern dike on Cell 4A. Data from this monitor indicate that it is stable. Due to the work being accomplished on Cell 2 and Cell 3 many of the monitors have had extensions added which can be seen in the chaiis by the sudden shifts in the plot lines. The settlement monitors on Cell 2 have all had extensions added. Cell 2 is continuing to have the slimes drain system pumped and it appears that most of the monitors are continuing to settle. The settlement monitors on Cell 3 appear to show mixed trends. The slimes drain system in Cell 3 is not being pumped as the cell is still active. The east end appears stable. This is where the cover has been in place the longest. The west end is showing a slow settling trend. This is likely attributed to the latest cover placement. The monitors on the west end had extensions added as can be seen in the charts due to the reclamation cover that was added. The requirement to place monitors over 1 le.(2) disposal areas was added in 2012. These monitors are only required to be surveyed once per year. Charts for this data from 2012 to present are included in this report. The data shows the 1 le.(2) settlement monitors to be stable with no significant movement. Page 11 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 19, 2019 8.0 lle.(2) WASTE DISPOSAL There were 808 cubic yards of 1 le.(2) waste material received and disposed of during the evaluation period, all of which was placed in Cell 3. This evaluation included review of documentation and procedures to confirm that each load of 1 le.(2) material was placed and documented in accordance with the Standard Operating Procedures for 1 le.(2) Byproduct Disposal. The review confirmed that only materials approved by the RSO were received and disposed, that each load has been placed, compacted, and covered consistent with the requirements of the SOP, and that Mill personnel have been documenting each load consistent with the requirements of the SOP. 9.0 TAILINGS TRANSPORT SYSTEM The tailings slurries and solutions are transported to the tailings cells via HDPE pipelines. During mill operation these lines are inspected on a daily basis for leaks or other potential problems. The tailings solids produced during this period of evaluation were transported to Cell 4A. The pipelines are run to the interior of the cell such that the discharge does not impact the dikes or cell liner. In Cell 4A and Cell 4B the pipes are run down "splash pads", which are an added layer of liner on top of the standard cell lining. 10.0 CONCLUSIONS AND RECOMMENDATIONS The White Mesa Uranium Mill Tailings Management System is functioning as designed according to the routine inspection reports and the observations from this Annual Technical Evaluation conducted on November 11th through November 18th, 2019. The inspection records were complete and the personnel involved were adequately trained to detect any abnormalities or signs of distress in a timely manner. The general condition is very good with all aspects being maintained attentively. The following items should be monitored or addressed: Page 12 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 19, 2019 • Prairie dog activity should continue to be controlled in areas around tailings cells and diversion channels. • The erosion channels on the north embankment of Cell 1 should be maintained. • Blown sands should be cleaned up around the Cell 3 Spillway area. 11.0 REFERENCES The following documents were used or referenced in the annual technical evaluation of the White Mesa Uranium Mill Tailings Management System: State of Utah Radioactive Materials License No. UT1900479 Amendment #08, dated February 161h 2018 U.S. NRC Materials License SUA-1358 with Amendment No. 13, dated February 10, 2000 "Site Selection and Design Study, Tailings Retention and Mill Facilities" by Dames & Moore, May 15,1978.
