The License incorporates the White Mesa Mill's Standard Operating Procedures contained in the 1987 U.S. Nuclear Regulatory Commission renewal application. These documents reference the White Mesa Environmental Protection Manual, Section 3.1, Appendix E, Revision 1, dated December 1998, and provide 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 was performed on November 7rd through the 9th, 2011, 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 7 -9,2011 • 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 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. Page 2 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 7 -9,2011 Operations During the period covered by this evaluation, November 2010 through October 2011, the mill was in operation processing uranium/vanadium ore from the company's mines, UF4 material from Cameco Corporation, and CaF2 material from Honeywell. The mill processed UF4 and then CaF2 throughout the period covered by this evaluation. The mill processed the uranium/vanadium ore through June 2011 and then resumed in September 2011. During mill operations various solutions and solids were discharged to the mill tailings cells. The solids were discharged to Cell 3 and Cell 4A. Cell 1 and Cell 4B were maintained as evaporation cells, and only raffinate solution from the solvent extraction circuit and process water from operational mill clean-up was discharged to them. In efforts to maintain freeboard limits solutions were transferred between cells. Site Management Mr. Rich Bartlett who was the White Mesa Mill Manager retired during the evaluation period. Mr. Dan Hillsten is the current White Mesa Mill Manager. Mr. Hillsten 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. UT 1900479. Mr. David Turk is the Radiation Safety Officer at the mill. His responsibilities include administering the required radiation and environmental safety programs and 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. Turk the trained inspectors are: • Ryan Palmer • Tanner Holliday • Garren Palmer 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. Page 3 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 7 -9, 2011 Records 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 July 2011 are included as a part of this evaluation. Also copies of all the monthly inspection summaries and quarterly reports are included as part of this evaluation. A review of these records was conducted to verify completeness, evaluate content, and to evaluate any unusual events. The record keeping is in excellent order and is consistent with the requirements in the Environmental Protection Manual. Diversion Channels To the north of the mill tailings cells there are three diversion channels and a berm which prevent runoff from flowing into the tailings cells and Mill yard area. Channel #1 was recently graded and was clean of any vegetation. The general condition is excellent. There was no noticeable prairie dog or other activity that would be detrimental to the function of this channel. It was found that there was some significant prairie dog activity in the general area and it is recommended that this be monitored and controlled to ensure it does not expand. Channel #2 had not been graded and had minor vegetation covering it. Impact of this vegetation would be minimal and would not impact the function of channel. The general condition was good with the exception of the Southern end where it appeared that some equipment had been stuck and left some ruts around the channel. It is recommended that this area be graded. Channel #3 had not been graded and also had minor vegetation covering it. This vegetation would not be detrimental to the intended function either. The general condition is good and there are no recommendations at this time. There was not found to be and prairie dog or other activity observed within Channels #2 or #3. The Diversion Berm was in good condition and had minor vegetation covering it. Photograph No.1 through No.8 in the photo section of this evaluation show typical sections of all the diversion channels and the diversion berm north of the Mill facility. Page 4 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 7 -9, 2011 Tailings Disposal Cells Cell 1-1 Cell I-I was the second cell placed into service after being completed in 1981. The Cell was designed as an evaporation cell for tailings solutions only. No solids are to be placed into the Cell. The solution discharged to the Cell normally comes from the solvent extraction circuit, but solution is periodically pumped back and forth between CeIl4A, Cell 3, and Ce111-1 to maintain required freeboard limits in the entire system. The daily inspection reports indicated that solution was transferred between the cells during this evaluation period. 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-I is 5615.4 feet MSL. A review of the records found that there were no instances of the solution level in Cell 1-I exceeding the freeboard limit during the evaluation period. The south side of Cell I-I originally shared a dike with Cell 2. Cell 2 has since been filled and covered with the initial layer of engineered fill. The cover around the interior perimeter of the tailings cell has been disturbed as a result of maintenance that has been accomplished on the Cell 1 liner. The soil serves to cover and protect the liner from UV coming from direct sunlight. Though the liner was covered it is recommended that the soil be smoothed and dressed to prevent pooling and erosion due to precipitation. The attached Photographs No.9 through No. 12 shows views around the perimeter of Cell 1-1. The roadways around the cell are well maintained. 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 Page 5 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 7 -9, 2011 full. The first stage of reclamation has been completed by covering the cell with approximately four feet of random fill (platform fill) which prevents the migration of windblown tailings. In July of 2011 the surface of the cell was covered with additional fill and re-graded to prevent the collection of surface water. The disturbed surface has grass planted which is in its initial stages of growth. The Eastern end of the cell was left undisturbed and had established vegetation. Photographs No. 13 through No. 16 show the cell surface. In order to monitor the consolidation of the tailings sands contained within Cell 2 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. The south dike of Cell 2 is the north dike of Cell 3. As a part of the work on the Cell2 surface the spillway between Cell 2 and Cell 3 was covered as it no longer serves the intended purpose. The roadways around the cell are well maintained. Cell 3 Cell 3 was constructed and placed into service in 1983. It is currently an active cell for disposal of tailings sand as well as 11(e).2 waste materials from in-situ uranium producers. During the evaluation period, slurry tailings from conventional ore processing was being discharged to the Cell in several locations. Photograph No. 18 shows areas of deposited tailings solids. Cell 3 is in its final stages of being filled with tailings. In August and September of 2011 soil fill was brought in to cover tailings sands and also to tighten the boundaries of the tailings deposit area. This will help in controlling the solution level in the cell. Photographs No. 19 and 20 show the interim cover on Cell 3. The solution freeboard limit for Cell 3 was removed as it was no longer necessary with Cells 4A and 4B in service. The prior established maximum freeboard limit for Cell 3 was 5602.5 feet MSL. Page 6 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 7 -9, 2011 Records examined indicated that before the removal of the freeboard limit the level was continuously over this limit. The south dike of Cell 3 is shared with Cell 4A and Cell 4B. Photograph No. 21 shows the top surface of the dike between Cell 3 and Ce1l4A. Photograph No. 32 shows the top surface ofthe dike between Cell 3 and Cell 4B. The dike crest and all roadways around the cell are well maintained. Approximately 70% of Cell 3 has been covered with random fill. 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. Cell4A Ce1l4A was originally constructed in 1990 and was never used for disposal of tailings material other than process solutions during the first years of its operation. 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 Ce1l4A dikes are currently the final containment of tailings at the White Mesa Mill site. The east and south dike slopes were covered with moderate vegetative growth. There is no indication of any significant erosion other than the minor rivulets that typically occur from surface water. These slopes are shown in photographs No. 25 ,27, and 27. The west dike is shared with Ce1l4B. The top surface and roadways on the dikes are all well maintained. The established maximum freeboard limit for Ce1l4A also has been removed. The prior established freeboard limit was 5595.3 feet MSL. Records examined indicate that the level was above this limit Page 7 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 7 -9, 2011 in January 2011. This is directly before the approval of the use of Cell 4B and the subsequent removal ofthe freeboard limit on CeIl4A. Cell4B Cell4B 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 CeIl4A. This cell currently serves as the final collection point for tailings solutions. The South dike is shown in photograph No. 38. There is minor vegetation beginning to cover the dike. There is no indication of significant erosion other than the typical rivulets that occur from surface water. The top surface and roadways on the dikes are all well maintained. 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 ofthe current license. The established maximum freeboard limit for Cell4B is 5624.0 feet MSL. A review of the records found that there were no instances of the solution level in Cell I-I exceeding the freeboard limit during the evaluation period. 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 South Cell4A dike and the South Cell4B dike. The survey data was provided by Jones and Demille Engineers of Richfield, Utah, along with the previous two years points. It does not appear that there is any significant movement ofthe boundary dikes. None of the monuments moved more than 0.1 feet except for Monument 403 which dropped 0.12 feet. None of the adjacent monuments reflected significant movement that would indicate settling or movement of the dike. Page 8 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 7 -9, 2011 Settlement Monitors Elevation survey of all settlement monitors are taken monthly. The trend of the data from these monuments shows the settling or stability of the tailings sands. Cell 2 has continued to show a settling trend on most monuments. The monuments on Cell 3 appear to be fairly stable. On the western monuments on Cell 2 the final survey point is dropping off an average of 0.64 feet. This is consistent for all the western monuments which are referenced off of one point. It is assumed that this is due to either a disturbance of the reference point or inspector error. Follow up measurements will identify which. The collected data and charts for each settlement monument are included with this evaluation. lle.(2) Waste Disposal There were 3,088 tons of lle.(2) waste material received and disposed of during the evaluation period. All of which was placed in Cell 3. 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 majority of tailings 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 Cell4A the pipes are run down "splash pads", which are an added layer of liner on top of the standard cell lining, into the cell. Page 9 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 7 -9, 2011 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 7,8, and 9, 2011. 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 following items should be monitored or addressed: • The vegetative growth is moderate in all portions of Diversion Ditch No.2 and Diversion Ditch No.3. Growth of vegetation should continue to be monitored during routine inspections and maintenance action taken as necessary. • Vegetative growth along the Ce1l4A dike faces is moderate on all areas of the dikes. The continued growth of vegetation should be monitored to ensure that it does not grow heavy or dense such that inspection cannot be accomplished. • Annual refreshers on the requirements and operation of the Tailings Management System had been given to all personnel that are currently conducting the inspections. Annual refreshers for the inspectors are recommended, particularly with the additional requirements that are included in the Ce1l4A BAT Operations and Maintenance Plan. Trainers should ensure that all the inspectors have read and understand the Ce1l4A BAT Operations and Maintenance Plan. Documentation of the most recent training of inspection personnel was well organized and available for review. • Cell 3 is very near capacity and is expected to be closed to solids deposit by the next evaluation. As the newly formed beaches begin to dry, potential from blowing tailings should be monitored. There was no evidence of any recent blowing tailings sand. Conditions should continue to be monitored after the tailings sands are graded to final contour. Page 10 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 7 -9, 2011 • Surface water erosion on the exterior slopes of Ce1l4A and Cell4B should be monitored and repaired as necessary. • Prairie dog activity was found in the vicinity of Cell I and Diversion Ditch 1. The activity was not detrimental, however it should be monitored and control to prevent expansion. Page 11 Respectively submitted, J?&=,re. $'~ Steve R. Snyder Mill Engineer Denison Mines (USA) Corp.
