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 3rd and 4th, 2010, in accordance with the White Mesa Mill Environmental Protection Manual and consisted ofthe following elements: • Review ofthe 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 3 -4, 2010 • 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 dike centerlines, 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 ofthe 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 3 -4, 2010 Operations During the period covered by this evaluation, August 2009 through October 2010, the mill was in operation processing uranium/vanadium ore from the company's mines and UF4 material from Cameco Corporation. The mill processed UF4 throughout the period covered by this evaluation. The mill processed the uranium/vanadium ore starting in March 2010. 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 was maintained as an evaporation cell, and only raffinate solution from the solvent extraction circuit and process water from operational mill clean-up was discharged to it. In efforts to maintain freeboard limits on all three cells solutions were transferred back and forth between cells. Site Management Mr. Rich Bartlett is the current White Mesa Mill Manager. Mr. Bartlett 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. 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 ofthe 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 3 -4, 2010 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 December 2009 are included as a part ofthis 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 runofffrom flowing into the tailings cells and Mill yard area .. Channel #1 and Channel #3 were both recently graded and were clean of any vegetation. It was found that there was minimal prairie dog activity in Channel #1 and zero activity in Channel #3. 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. There was no prairie dog activity observed within Channel #2. The Diversion Berm was in good condition and had minor vegetation covering it. Photograph No.1 through No.1 0 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 3 -4, 2010 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 Ce1l4A, Cell 3, and Cell I-I 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 ofthe 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 I-I is 5615.4 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. 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 fill in and around the Cell 1-I dikes appear to be in fair and stable condition. The attached Photographs No. II through No. 13 shows views around the perimeter of Cell I-I. The east dike showed signs of recent work where liner repairs have been made. 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 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. The surface is Page 5 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 3 -4, 2010 covered with native vegetation. vegetation covering. Photographs No. 15 and No. 16 show the platform fill with 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. There is a spillway which collects all storm runoff from Cell 2 into Cell 3. The spillway is in good working condition and has no obstructions to affect its operation. Photograph No. 14 shows the spillway between Cell 2 and Cell 3. 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. 20 and No. 21 show areas of deposited tailings solids. The south dike of Cell 3 is shared with Ce1l4A and Cell4B which is under construction. Photograph No. 23 shows the top surface of the dike between Cell 3 and Cell4A. Photograph No. 22 shows the top surface ofthe dike between Cell 3 and Cell 4. The dike crest and all roadways around the cell are well maintained. The construction of Cell 4B has changed the remaining portion of exposed Cell 3 dike. In constructing the cell the ground below the dike was blasted and removed. The surface of the dike was re-graded in accordance with the approved Ce1l4B design. Approximately 50% of Cell 3 has been covered with random fill. In order to monitor the Page 6 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 3 -4, 2010 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. The solution freeboard limit for Cell 3 is established in Section 3.0 to Appendix D of the approved license application, and modified by license amendment in October of 1999, and confirmed as License Condition 10.3 of the current License. The established maximum freeboard limit for Cell 3 is 5602.5 feet MSL. Records examined indicate that there have been several instances of the pond level exceeding this level during the evaluation period. The cell is nearing capacity, and it has become increasingly difficult to stay below freeboard limit as the solution capacity is minimal. Ce1l4A Cell4A 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 of2007 and finishing in the summer of2008. The Cell was placed into service in October of2008. The Cell4A 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 through No. 27. The west dike has also been changed by the construction ofCe1l4B. The top surface and roadways on the dikes are all well maintained. The established maximum freeboard limit for Cell 4A is 5595.3 feet MSL. Records examined indicate that there were no instances where this level was exceeded during the evaluation period. Page 7 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 3 -4,2010 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 existing boundary has been along the south Cell4A dike, the west Cell4A dike, and the west half of the south Cell 3 dike. The construction of Cell 4 B removed all the monitors along the west Cell 4A dike and the Cell 3 dike prior to survey this year. Therefore, the data for this evaluation is only from the south Cell4A 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 of any monuments. None of the monuments moved more than 0.1 feet except for Monument 416 and Monument 425. In the case of Monument 416 and Monument 425 the movement appears to be a rebound from some questionable 2009 data. When compared with 2008 data the overall movement falls back under 0.1 feet. Upon completion ofthe south Ce1l4B dike it will become the new boundary and will have movement monuments installed. 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 ofthe 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. Page 8 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 3 -4, 2010 Ile.(2) Waste Disposal There were 2,523 tons of lle.(2) waste material received and disposed of during the evaluation period. 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 3. The pipelines are run to the interior of the cell such that the discharge does not impact the dikes or cell liner. In Ce1l4A the pipes are run down "splash pads", which are an added layer ofliner on top of the standard cell lining, into the cell. Page 9 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 3 -4, 2010 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 3 and 4, 2010. 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 non-existent in Diversion Ditch No.1 and No.3. Growth of vegetation should continue to be monitored during routine inspections and maintenance action taken as necessary. It is unlikely that significant growth will occur during the remaining months of this calendar year. • 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. • As Cell 3 is in the final stages of filling with solid tails, it is not realistic to maintain solution levels below the established freeboard. Ce1l4A is in service with the associated spillway between Cell 3 and Ce1l4A, and Ce1l4B is nearly complete with a spillway between Ce1l4A and Ce1l4B. It is recommended that the freeboard level in Cell 3 be reevaluated. • 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. Page 10 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System November 3 -4.2010 • The discharge of tailings slurry along several points in Cell 3 has eliminated further potential for wind blown tailings. 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. • Surface water erosion on the exterior slopes of Ce1l4A should be monitored and repaired as necessary.
