Reference documents are listed in the Reference section at the end ofthis summary. This Annual Technical Evaluation was performed on August 18th and 19th,2009,in accordancewith the White Mesa Mill Environmental Protection Manual and consisted of the 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 ofthe requirements. •Review ofrandomly selected daily,weekly,monthly,and quarterly inspectionrepOlis 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 ofthe inspection reports. Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System August 18 -19,2009 •Inspection of the tailings embankments and appurtenances for signs of distress or concern that could potentially affect the stmctural 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 ofthe survey conducted on Movement Monitors along the dike centerlines, and comparison ofthe 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 ofmaintenance activities in the tailings area that have the potential to affect the integrity ofthe tailings dikes or liner system. •Photographic documentation ofthe 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 August 18 -19,2009 Operations During the period covered by this evaluation,August 2008 through July 2009,the Mill was processing conventional ore from the Company's mines,and had recently started up the new alternate feed processing circuit.UF4 material from Cameco Corporation was being processed in the alternate feed circuit.Effluent discharged to the tailings system during the period covered by this evaluation consisted of conventional uranium/vanadium ore slurry and raffinate (barren solution) from the solvent extraction circuit,small quantities of process water from mill clean-up activities, and a small amount ofprocess tailings from the Cameco UF4 material.During the conventional ore processing,solutions were being recycled from Cell 3 and Cell 1 to the CCD circuit to be used as wash water.Throughout the time period covered bythis evaluation,solutions were moved between Cell 3,Cell 4A and Cell 1-1 to maintain freeboard limits and maximize evaporation potential. Tailings solids were discharge to Cell 3 and Cell 4A during this evaluation period. Site Management Mr.Rich Bartlett is the CUlTent White Mesa Mill Manager.Mr.Bartlett has the overall responsibility to ensure that the Tailings Management System is operated and maintained in accordancewith State ofUtah Radioactive Material License No.UT1900479.Mr.David Turk is the site Radiation Safety Officer.He administers the radiation and environmental safety programs and has day-to-day responsibility for regulatory compliance in the operation ofthe Tailings Management System.The Mill shift foremen,and selected radiation and environmental safety technicians,are trained by Mr. David Turk or Ryan Palmer to do the tailings area inspections.The trained inspectors are the Mill shift foreman; •Roy Atcitty •Eric Balch •Thane Holt Page 3 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System August 18 -19,2009 •Gage Sterling. Additional trained inspectors are; •Jerome Benally •Herschel Bennett •Guy Holiday •Tanner Holliday •Sinn Mays •Ryan Palmer •Josh Taylor All ofthe inspectors had documentation ofrecent training on the inspection procedures.Mr.Turk also conducts inspections on days that other individuals are not available because ofother duties or scheduled absence. Records A review was conducted ofall ofthe records kept on a daily,weekly,monthlyand quarterly basis for the period covered by this evaluation.A copy ofthese records for the month ofDecember 2008 is attached to this evaluation.In addition to the review ofall the records,the December 2008 records were examined for technical content and completeness and to evaluate anyunusual events.Monthly summaries for all the Daily Inspections are also prepared by the White Mesa staff to highlight specific events in the tailings area.The Monthly Summaries are reviewed by the Mill Manager to ensure compliance with the inspections and operational procedures.All ofthe Monthly Summaries were reviewed for any unusual events.Copies ofthe Weekly Inspections for December 2008 are also attached to this evaluation with the DailyInspections.Monthlyand Quarterly Inspection reports for the evaluation period are also attached to this evaluation.The record keeping is in excellent order Page 4 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System August 18 -19,2009 and consistent with requirements in the Environmental Protection Manual. Diversion Channels Diversion channels constructed to the north ofthe Mill and tailings area were inspected.Diversion Channels #1, #2,# 3 and the belm located north of the Mill facility were inspected.The visual inspection confilmed that the channels have been well maintained.The vegetation in and around diversion channels # 2 and #3 was consistent with the previous year.There was clearly nothing observedduring this evaluation to indicate that vegetation would have an impact on the effectiveness ofthe channels for the intended purpose.Diversion channel #1 had recently been graded and had no vegetation.The channels exhibited evidence of recent inspection activities.There was some evidence ofprairie dog activity in the vicinity ofthe # 1 channel.The attached Photographs No.1 through No.24 show typical sections ofall the diversion channels and the diversion berm nOlih of the Mill facility.Comments in the inspection reports indicate that the inspectors have a good understanding ofthe function ofthe diversion channels and the necessary maintenance required to keep the channels functional. 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 to hold and evaporate tailings solution 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 Page 5 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System August 18 -19,2009 periodically pumped from Cell 3 to maintain required freeboard limits in the entire system.The daily inspection reports indicated that solution was transferred back and forth between Cell 1-1 and Cell 3 dming 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 10.1 ofthe current License. The established maximum fi'eeboard limit for Cell 1-1 is 5615.4 feet MSL.Records examined indicate that there were no instances exceeding this level during the evaluation period. The engineered fill between Cell 1-1 and Cell 2 shows no signs of instability.The attached Photographs No.25 and No.26 show views around the perimeter ofCell 1-1 and the discharge point for transfer ofsolution fi'om Cell 3.Photograph No.25 shows the area ofrecent liner repair.There were nothing unusual observed on the Cell 1 dike or around the perimeter of Cell 1. Cell 2 Cell 2 was the initial Cell constructed and was placed into service when the Mill first began processing ore in 1980.The Cell is cmTently at capacity.The remaining open area ofthe Cell was covered with platform fill during the prior year.The pump and pump barge had been removed from the area.The Cell is not allowed to receive slurried tailings or liquid effluent from the milling process.The Cell has been completely covered with approximately four (4)feet of random fill (platfOlm fill)to prevent the migration of wind blown tailings,and accomplishes the first stage in completion of Cell reclamation.The area is showing moderate growth of native vegetation. Photographs No.27 and No.28 show areas of Cell 2 recently covered with platform fill. Elevation readings on the existing settlement monitors are taken monthly and will ultimately be used to detelmine when acceptable consolidation ofthe tailings sands has occurred.A summary ofthe settlement monitor elevations is included with this report along with graphs ofthe settlement data. Page 6 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System August 18 -19,2009 The spillway between Cell 2 and Cell 3 was inspected and showed no signs of obstruction or alternation that could affect its function.Photographs No.29 and No.30 show the spillwaybetween Cell 2 and Cell 3. Cell 3 Cell 3,constructed in 1983,is the current active Cell for disposal oftailings sand as well as 11 (e).2 waste matetials fi'om in-situ uranium producers.A small amount ofclean-up material from Cell4A is still present near the east-central part of the Cell.This material has also been used to aid in the prevention of blowing tailings sand on exposed areas ofthe Cell.During the evaluation period, slurry tailings from conventional ore processing was being discharged to the Cell in several locations.Photographs No.31 and No.32 show the regarding of an area of recently deposited tailings solids.Photographs No.33 and No.34 show the top surface ofthe dike between Cell 3 and Cell 4.The dike crest is exceptionally well maintained. The solution freeboard limit for Cell 3 is established in Section 3.0 to Appendix D ofthe approved license application,and modified by license amendment in October of 1999,and confirmed as License Condition 10.3 ofthe CUlTent License.The established maximum freeboard limit for Cell 3 was evaluated in September of2008 and adjusted to 5602.5 from the previous elevation of 5601.6 feet MSL.Records examined indicate that there was one (1)instance ofthe pond level exceeding this level,by 1.4 inches (0.12 foot),during the evaluation period and prior to the installation and approval ofthe spillway from Cell 3 to Cell 4A.This instance is not considered significant or a threat to the overall safety ofthe tailings system and was reported to be the result of mechanical problems with the Cell pumping system and the problem was quickly remedied.The subsequent weekly solution level readings were well below the freeboard limit. The downstream area ofthe Cell 3 dike showed no signs ofinstability or evidence ofany unusual occurrence in the engineered fill.The dike slope supported moderate vegetative growth and showed little or no evidence of surface water erosion.Photographs No.39 through No.50 show various Page 7 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System August 18 -19,2009 sections and views ofthe Cell 3 dike and examples ofvegetative growth on typical areas ofthe Cell 3 dike.As reported during the last evaluation,prairie dog activity was not evident at any point along the dike,or in the areas immediately south ofthe dike fills.Because ofthe installation ofthe new liner on the north side ofCe1l4A it was impossible to view any area ofthe downstream face ofthe Cell 3 dike on the north side ofCell 4A. Approximately 50%ofCell 3 has been covered with random fill.Elevation readings onthe existing settlement monitors are taken monthly and will ultimately be used to determine when acceptable consolidation ofthe tailings sands has occun'ed.A summary ofthe historical settlement monitor elevations is included with this report,along with graphs ofthe settlement data. Cell4A Ce1l4A was originally constructed in 1990 and was neverused for disposal oftailingsmaterial 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 matelials 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 established maximum freeboard limit for Cell 4A is 5595.3 feet MSL.Records examined indicate that there were no instances exceeding this level during the evaluation period. The Cell 4A dikes were inspected and showed no signs of instability or evidence of any unusual occurrence in the engineered fill.The dike slopes supported moderate vegetative growth on the west-facing slope with less vegetative growth on the south-facing slope.Photographs No.51 through No.74 shows the dike slopes and examples oftypical vegetative growth on the Ce1l4A dike slopes. There was some evidence ofminor surface water erosion in several small areas ofthe east-west Cell 4A dike.There was no prairie dog activity along either dike.The top surface ofthe dike was well maintained.Photographs No.75 and No.76 show the top ofboth Cell 4A dikes. Page 8 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System August 18 -19,2009 Movement Monuments The usefulness ofthe Movement Monitor data is in comparing the data from year to year,or over a several-year time period,to determine ifthere is CUlTent and continued horizontal or vertical movement in the dike fills.During the Annual Technical Evaluation,the most recent survey data is compared by the evaluator to the last several years'data in order to detect any abnormal occurrences.The majority ofthe Cell4A points were disturbed during the Cell re-lining activities and were re-set in the fall of2008.For these points there is no meaningful comparison back to previous points. Points are sometimes disturbed by maintenance activities.The disturbance of a single point is not significant because any catastrophic or large-scale movement in the dike fills would be noticeable in several ofthe monitor points,not just a single point.The potential for future disturbance ofmonitor points is always possible,and Mill maintenance personnel are cautioned to avoid the areas ofthe movement monitors during routine maintenance activities. None ofthe points along the Cell 3 dike or the two (2)Cell4A dikes show any abnormal movement.There is no trend in the Cell 3 or Cell 4A movement monitors. Survey data provided by Jones and Demille Engineers ofRichfield,Utah,was reviewed during the evaluation.The current data was compared to the previous two (2)years data.Evaluation of the data indicated only very minor movement may have OCCUlTed along the Cell 3 dike and the north south Cell 4A dike.All the possible movements were within expected and acceptable limits. Page 9 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System August 18 -19,2009 Settlement Monitors Elevation readings on all settlement monitors were reviewed during the evaluation.Several ofthe monitors in Cell 2 have shown significant vertical movement over thepast three (3)years.The cause ofthe apparent movement is not known,but could be related to on going slimes drain dewatering. The data will continue to be monitored by the Mill environmental staff.A summary ofthe data is included with this RepOli along with graphs ofthe settlement data. lle.(2)Waste Disposal There were 581 tons of11 e.(2)waste material,from two different sources,received and disposed of during the evaluation period. Tailings Transport System The tailings slurry and raffinate pipelines were inspected on a daily basis when the mill was operating according to the inspection reports.Tailings slurry from conventional uranium/vanadium ore processing was being discharged into Cell 3 and Cell 4A during this evaluation period.The slurry was discharged well into the interior ofCell 3 and there was no potential for impact to the Cell dikes or lining system fi'om the slurry discharge activities.The slurry was being discharge into Cell 4A along the north interior slope of the Cell,utilizing the protective splash pads constructed specifically for that purpose.There was no evidence that tailings discharge had adversely affected the liner system. Page 10 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System August 18 -19,2009 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 August 18 and 19,2009.The inspection records were complete and the personnel involved were adequately trained to detect any abnormalities or signs ofdistress in a timely manner.The following items should be monitored or addressed: •The vegetative growth is moderate in all portions ofthe Diversion Ditches No.2 and No.3 and non-existent in Diversion Ditch No.1.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 ofthis calendar year. •Vegetative growth along the dike faces is moderate on all areas ofthe dikes.The growth of grasses and weeds on the dikes should be monitored and efforts should be made to remove new growth of taller vegetation from the dike slopes of Cell 3 and Cell 4A in order to facilitate inspection ofthe dikes. •The spillway installed between Cell 2 and Cell 3 and between Cell 3 and Cell 4A,designed to pass the Probable Maximum Flood into the Cell 3and Ce1l4A impoundments,are both in very good condition.The condition ofthe spillways should continue to be monitored. •Annual refreshers on the requirements and operation ofthe Tailings Management System had been given to all personnel that are currently conducting the inspections.Annual refreshers for the inspectors are recommended,patiicularly 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 Cell 4A BAT Operations and Maintenance Plan.Documentation ofthe most recent training ofinspection personnel was well organized and available for review. Page 11 Annual Technical Evaluation White Mesa Uranium Mill Tailings Management System August 18 -19,2009 •The potential for prairie dog activity along the south and west facing slopes ofCell 3 and Cell 4A should be monitored.There is some evidence of any prairie dog activity near Diversion Ditch No.1,but it is not significant at this time.A control program should be implemented is they move nearer to the diversion structures. •The discharge oftailings slurry along several points in Cell 3 has eliminated further potential for wind blown tailings.As the newly fonned beaches begin to dry,potential from blowing tailings should be monitored.There was no evidence ofany 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 ofCell4A should be monitored and repaired as necessary.
