The purpose of the review was to determine compliance with the requirements of License Condition 9.4 of your facility's Radioactive Material License Ln 1900479. The following deficiencies were identified: o Members of the SERP, as defined in License Condition 9.4.C., were not documented in the report; ando Changes to existing and new procedures that were reviewed by the SERP were not attached to two of the annual SERP reports as required in License Condition 9.4.D. These deficiencies are considered minor in nature and are not a safety or environmental concern. However, the Division expects the required information to be included in future SERP reports. Please find enclosed copies of the report reviews. Ifyou have any questions, please call Ryan Johnson at (801) 536-4255. Sincerely, Scott T.

Subject l: Review and approve modifications to the Uranirm Solvent Extraction ("SX') circuit configrration and rcvisions to the Sandard Operating Procedure for the Uranium SX circuit (the Uranium SX SOP"). SOP Book 4 Sections 2 and 3. Subject 2: Review and approve revisions (the "Calcined Change') to the Calcined altemate feed material ('Calcined Material') Standard Operating Procedure (the I'SOP" or "Calcined Material SOP") for processing of Calcined Material from Cameco Corporation's Blind River Facility. PBL-I3, Nodes I through 3 (the "Procedure') Subject 3: Review and approve modifications to the Calcined alternate feed material ("Calcined Material") drum urloading area/feed addition area for feeding of Calcined material from Cameco Corporation's Blind River Facility (the'Drum Unloading Change"). Subject 4: Review and approve revisions (the "KF Change") to the KF alternate feed materid ('KF Materialn or nKF") Standard Operating Procedure (the 'SOP' or "KF SOP') for proccssing of KF Material from Cameco Corpora{on's Port Hope Facility. 2) Did the subject(s) meet the criteria found in License Condition 9.4.A? Yes X No Exolain: Subject l: The SERP reviewed the proposed revision and determined that: o Since the Change was limited to r€-arrangement of piping, it involved no new feeds, reagents or other materials, or changes to rates of addition. o The Change does not generate any new radiation or occupational safety issues. o The Chanee has no impact on environmental emissions or on thqtai[lqgryyge4q Subject 2: The SERP reviewed the Procedure described above and concluded that: o The Calcined Change will eliminate the use of two reagents (ammonia and caustic) for this feed, and will reduce the concentation of sulfuric acid requircd for this fbed. o The prrocess will use the sarne solvent extaction and drying and packaging nodes as used for ores and previously used for this alternate feed. . o Asa result, no new Personnel Protective Equipment ("PPE") would be required, no changes to derived air concentration ("DACs") would be required, and no new radiation or safety issues would be produced by the Calcined Change. o There would be no increase in environmental emissions and no change in nature or volume of tailings due to the Calcined Change \\EeVMMFS03SFcbrod\StHWRADEOMlvlONlJrroiun milb\ltTl90Ol?9 Eocr6rFuclr Rcr - Wbil,e ldc..

Therefore, there are no anticipated new environmental emissions or emission sources, no additional impacts on existing worker safety and no effects on the process or the tailings system. The Drum Unloading Change will allow the tansfer truck to pull closer to the emptying statioq and will provide a mqpr.ts to Prevent antconlact belveen residual wash water in the drums with the ground surface subject 4: The SERP evaluated the proposed KF change and determined that:o Based on a radiological characterization of a composite from a number of drums, the KF material is comparable to previous KF material received and processed at the Mill.. The proposed KF Change to the SOP will provid,e improved management of fluoride ion from the KF. The KF Change will remove the fluoride ion in a water environment, leach the uranium in a carbonate environmenf and eliminate any oppodunity for fluoride exposure to sulfuric acid.o The processing will not require the use of any additional chemicals beyond those alr,eady in storage and use at the Mill, and due to the eliminatiron of sulfuric acid from the processing will use fewer chemicals and fewer process steps. Therefore, there will be no new emissions or emissions sources, no new sources of exposure to workers or the public, and no changes in DACs or PPE DWMRC Staff Review: Each of the four subjects reviewed by the SERP were changes in procedures and processes. Therefore, the subjects reviewed by the SERII meet the criteria in License Condition 9,4.A. 3) Did the subject(s) meet the criteria found in License ition 9.4.8?Yes X_No Subject 1: The SERP concluded that:o The Change, does not conflict with any requi such as yellowcake production, specifically stated in the license. Because it has no effect on operations in any aspect addressed by any ofthe feeds or emissions, it does not affect Mill permits or any regulations.o The Change will not produce any degradation in lhe essential safety or environmental commitments in the License application, its is within the envelope of environmental conditions assumed in the EA, and it has no effedt on reclamation commitments. The Change will not modify t)?es or rates of feed, will not produce any new environmental emissions, and has no effect on tailings.o The Change does not involve any new feeds, wastes, process material or operating conditions, and would therefore produce nd environmental impact beyond those assessed in the EA dated February t997. Subject 2: The SERP concluded that:o The Procedure, as amended by the Calcined Change, does not conflict with any requirements specifically stated in the license, or impair EFRI's ability to meet all applicable regulations. The material is already covered by an existing license amendment. The Mill has remained in compliance with the License and other regulatorl, requirements while running this and other feeds requiring more prccessing stages and reagents tlurn the revised Procedure.o The Calcined Change will not produce any degradation in the essential safety or environmental commitnents in the License applicatioq or provided by the approved reclamation plan. The Calcined Change involves a feed already processed previously at the Mill, and involves no new reagents, chemical or radiological hazards or environmental emissions. Ii would have no effect on the volume or nature of tailings.o The Calcined Change is not expected to produce Ery environmental impacts beyond those assessed \\EQVMMFS03Sfuhatcd\SHW\RAD€OMMOMUraniun mills\UTl9dll?9 ErcrgFulb Rcs - Whitc M6r UMillUlP tmpoctioo modulcsUOl5\RADMODSERP-0l 2012- pg.docr P4e2of1 in the EA dated Febnrary 1997, and is consistent with the conclusions regarding actions analped in the EA. The Calcined Changd would use fewer and/or lower concentration of reagents than assumed in the EA, and produce no new environmental emissions. The volumes of solutions and solid tailings that would be ransferred to the tailings cells will remain the same. There would be no new pathways of exposure to workers or the public. Subject 3: The SERP concluded that:o The Drum Unloading Change does not conflict with any requirements specifically stated in the license, or impair EFRI's ability to meet all applicable regulations. It will improve EFRI's ability to comply with Part I.D.I l.d of the Mill's Growrdwater Discharge Permit.r The Drum Unloading Change will not prduo€ any degndation in the essential safety or environmental commitnents in the License application, or provided by the approved reclamation plan, and thenefore this criterion is met. The reclamation surety estimate alrcady addresses removal and disposal of surface concrpte and the additional volume of concrete resulting from the Drum Unloading Change is too small to affect the estimate.o The Drurn Unloading Change has no effect on any assumption or condition aszumed in the EA dated February 1997. Therefore, the Drum Unloading Change is not expected to produce any environmental impacts beyond those assessed in the EA, and is consistent with the conclusions regarding actions analyzed in the EA. Subiect 4: The SERP concluded that:o The KF Change does not conllict with any requirements specifically stated in the License, or impair EFRI's ability to meet all applicable rcgulations. Processing of the feed is already covered by an existing license condition. The Mill has remained in compliance with the License and other regulatory requirements while rururing a comparable process as will be rcquired under the KF Change. The yellowcake recovered from the KF material will not cause the Mill to exceed the yellowcake production limit under the License.o The KF Change (increase in volume) will not produce any degradation in the essential safety or environmental commitnents in the License application, or provided by the approved reclamation plan, and therefore this criterion is met. The KF Change will not affect the volume of tailings, which would be the same whether tbe forrrer or proposed process is used.o The KF Change is not expected to producc any environmental impacts beyond those assessed in the EA dated February 1997, and is consistent with the conclusions regarding actions analyzed in. the EA. All r€agents proposed in the change are within the envelope of materials considered in the EA.

WHITE MESA URANIUM MILL RADIOACTTVE MATERIAL LICENSE UT 1 900479 References: Utah Administrative Code RML UT 1900479 License Condition 9.4 l) Describe what subject(s) were reviewed by the Mill's SERP, Subject 1: Energy Fuels Resources Inc. (EFRD is in the process of evaluating uranium recovery approaches and design for a proposed heap leaching facility to process natural uranium ores at EFRI's Sheep Mountain Wyoming site. The proposed heap leach design required the collection of performance data from a two-column pilot test, referred to as the "Test", to approximate conditions in a heap leach pile at the Sheep Mounuin Wyoming site. The proposed Test was to be conducted at White Mesa Mill (the 'Mill"). Any collected liquors frsm the test which were not shipped off-site for analysis would be processed in the Mill's uranium recovery circuit. Residuals (tailings) from &e column test would be disposed in the Mill's tailings system. Subject2: The"Mill has an existing License amendmentto process KF altemarc feed material from Camecn Corporation, and proposes to modi& the rccovery process as reflected in revisions to KF Node Worksheets 3, 5, and 6. The Mill has previouslyprocessed KF alternate feed material in the main Mill circuit by acid leaching prior to 2012, and by alkaline leaching following the process revision apprwed in the Jrure 2012 SERP evaluation (SERP 2012-04r. The previous process pcrformed caustic digestion under conditions selected to digest urudum, and perfonned the solid/liquid separation before caustic precipitation. The proposed revised process involves washing the solids for removal of fluoride, alkaline./carbonate leaching, and steam addition for temperature adjusbment and removal of any fluoride values. Following fluoride removal, the produced solids will undergo an additional sulfuric acid leaching step for recovery of uranium values. These proposed modific*ions to the alkaline/carbonate leach process as evaluated in this SERP are expected to _pqqCWJ higbg! qlaqlllql recoveries and require use of a smaller quantity of reagents. Subiect 3; EFRI planned to puriS. and concentrate hardened uranium ("ycllowcake") attached to drum shreds, which have been shipped in 85 gallon overpack drums, from the Honeywell Metropolis, Illinois conversion facility. The proposed process is a modification of processes in p,ractice at the Mill as described in the Mill's 2007 license renewal application and existing EA documents. The proposed system will redissolve yellowcake by attaching I processing lid to the overpack drum, placing it on a drum roller, adding sulfuric acid and sodiucr shlorate, mixing and draining of solution to a holding tank for reintroduction into the Mill's solvent extraction circuit 2) Didthe zubject(s) meet the criteria fomd in License Condition 9.4.X1 Explain: Subject l: Thc SERP reviewed the Test protoeols, and the Fcbruary 25,2Al3 Technical Memorandum by Jo Ann Tischler describing the test process and materials, and determined that:r If the recovered solumn solutions from the Test are to be processed in the Mill, the yellowcake \\EQVMMFSmSn$sedSHlV\RAD\COMlttOftnUisniuo nill3'iuTl900{?9 Fnlflyfuch Rcr - Wtitc Mc|r UMillutP lltrccrion f|odulGlUol'RADMODSERP-0| 20lf- Pg'do:rP{l I of4 Yes X No Year Reported Date of Report Date of Review 2013 March 31,2014 Julv 21. 2015 r The test will not involve any new chemicals ar aFry new or increased emissions. o Procedures for personnel training, monitoring ar{d personnel protective equipment are already in forMill em and conftactors who be involved in the Test. Subject 2: The SERP reviewed the Procedure above and the July 1,2013 Jo Ann Tischler Technical Memorandum evaluating the KF Process , and determined that: o The process will use the same carbonate,,and acid reagen* already used at the Mill for processing conventional ores and other alternate feed materials. The process will use a variation on the flocculant from the sarne farnily of anionic flocculants already used at the Mill. Although the potential for generation of HF ftorp exposure of fluoride minerals to sul$ric acid would be minimized as a result of the KFProsess Change, Mill safety personnel will continue to monitorfor HF in the process area- There are no changes proposed to the storage, unloading/dumping, or washing steps of KF processing. The leached and washed process liquids containing uranium win be transfened to the existing SX, precipitation, drying and packaging, areas with no modifications required, As a result, no new Personnel Protective Equipnrent ("PPE') would be required, no changes to derived air concentration ("DACs") would be reluiredn and no new radiation or safety issues would be produced by the KF Process Change. There would be no insrease in environmental endssions and no change in the nature or volume of tailings due to the Change. The volumes of solutions and solid tailings that would be transferred to the tailings cells will remain the same. There would be no new pathways of exposure to workers or the public. Subjint 3: The SERP reviewed the proposed Node rW'or:ksheets, engineering drawings, conlainmeut pad photographs, and November 13, 2013 Jo Ann Tischler Technical Memorandum describing the proposed Drum Shred Process and detennined that:r The material could be received as a licensee-to-licensee transfer of source material and could be purified and concentrated at the Mill.r The SERP assessed that there would b no du$ or vapor emissions of any significance from the process, and no wastes other than those typically produced by the Mill's existing solvent extraction and drying processe$, r The re-digested yellowcake will producethe ssme quantity of emissions as any other yellowcake in the Mill circuit. Because ttre process does not,involve storage of ores ot bulk feed materials, it will produce fewer fugitive esrissions/dusts thaq would be generated by producing the same quantily of yellowcake from conventional ores o[ other alternate feed materials o The Drum Shred Process does not require the rnpdifioation of the Mill's Air Approval Order or any other approved management plans. Approved prpcedures are already in place for the disposal of crushed drums in the Mill's tailings cells. l r Although the yellowcake encrusted on drum shrods is not an alternate feed material or other ore, the volume of tailings that will be generated during re-processing of the yellowcake wiil b significantly less than the tailings that would be generated by pro&rcing the same amount of vellowcake from ore DWMRC Staff Review: Subject I was a test or experirpent not presented in the application, Subject 2 was a change in an existing procedure and Subject 3 \*at a change in a process. Therefore, the subjects reviewed by the SERP meet the cdteria in License I I recovered will be minimal. tIr The qustrty of leached ore from the Test to {e disposed in the Mill's tailings will be immeasurably small compared to the capacitSiof the Mills tailings system. lEQvMMfs03Sllshar<[sHw\RAD{OMMON\lJrrnium rnilb\Ullgoo4?9 Emrplf{.fr n* - Wfti.

Explain: Yes X No Subject 1: The SERP coneluded that:o Tbe Test does not conflict with any requirements, such as yellowcake production, specifically stated in the license. Because it has no effect on Mill feeds or emissions, it does not affect Mill operations in any aspect addressed by any of the Mill's permits or any regulations.r Because the Test does not involve any ncw feeds, wastes, process materials or operating conditions, it will not produce any degradation in the essential safety or environmental commitments in the License application and will not produce any environmental impacts beyond those assessed in the EA dated February 1997.. The test will have no effect on reclamation commitments, and will not cause the Mill to exceed its approved tailings capacity. Subject 2r The SERP soncluded that:o The KF SOP, as amended by the KF Process Change, does not conflict with any requirements specifically stated in the license, or impair EFRI's ability to meet all applicable regulations. The material to h processed is already covered by an existing license amendment and has previously beerr processed according to the conditions of the license amendment and Licerse Condition l0.l L The Mill has remained in compliance with the License and other regulatory requirements while running a comparable process, and fully expects to rernain in compliance with the same requirements when running the revised process.o The KF Process Change will not produce any degradation in the essential safety or Environmental commiments in the License application, or provided by the approved reclamation plan. The KF hocess Change involves a feed already processed previously at the Mill, and involves no new . reagents, chemical or radiological hazards or environmental emissions.o The KF Process Change will have no effect on the Reclamuion Plan. The volumes of solutions and solid tailings that would be transfened to tailings would be the same whether the KF Material were processed by the existing SOP or the proposed Change to the SOP. It would have no effeet on the volume or nature of tailings.o The Yellowcake recovered from the KF altemate feed materid will not cause thc Mill to exceed the yellowcake production limit under the Mill's license.o The KF alternate feed material processing is addressed by an existing approved license amendment and its scope is within the envelope of environmental conditions assumed in the EA. Subject 3: The SERP concluded that:o The Drum Shred Process is consistent with the plans and SOPs referenced in the approved License and its renewal application. The Mill is already approved to process, puriry, and concentrate yellowcake and to dispose of cnrshed empty drums in the tailings system, which the Mill has followed on a routine basis. The drum handling and drum rolling area was designed consistent with requirements of the Discharge Minimization Technology plan and Stormwater Best Management Practices Plan. The Drum Shred Process will have no effect on the Reclamation Plan. The yolumes of solutions and solid tailings that would be transferred to tailings will be significantly less than those that would be generated by producing the sa$le amount of yellowcake from eonventional ore or alternate feed materials" The Drum Shred Process is nol expected to produce any environmental impacts beyond those assessed in the EA dated February 1997, and is consistent with the conclusions regarding actions analvzed in the EA. t\EQVI\lMF$03SPslwcSSHW\RAD\COMMOI.I\Urmiurn mills\UTlgfiX7g EoerglFu.l!

Subject l: The Mill has an existing License amendment to process KOH alternate feed materials from Honeywell, (formerly known as Allied Signal Corporation, Metropolis lllinois), and proposes to modi$ the recovery process. The Mill has previously processed KOH alternate feed materialsth,rough the addition of water to the drums manually, by Mill personnel, prior to dumping. The previous leach process used this water leach pnocess to remove sodium and potassium salts followed by acid leaching and an ammonium sulfate precipitation step. The revised process does not add water to the drum prior to dumping, but uses an automated dumping system that submerges the drums in water prior to dumping. The revised proc€ss eliminates the water leach process and ammonium sulfate precipitation step because neither the water leach nor the ammonium sulfate precipitation appreciably increase the uranium recovery. The proposed modifications to the process are expected to reduce the potential for worker exposure tbrough the submerged dumping station and to produce higher wanium recoveries and require the use of less water and fewer reagents, specifically the ammonium sulfate reagent. than the process approved in the previous SOP. 2) Did the subject(s) meet the criteria found in Lisense Condition 9.4.A? Explain: Subject 1:. The SERP reviewed the Procedure described above and deterrrined that: r The Change will not require the use of any new chemicals, but will eliminate the use of additional water and ammonium sulfate, thus reducing the amount of chemicals used in the production pI€cesses.o The Change will not produce any additional respiratory hazards beyond those already managed at the Mill in connection with other leach processes. There will be no new ehemical reactions or oft gasses associated with processing KOH under the SOP, as amended by the Change, that haven't been experienced and handled safety by the Mill in connection with processing other alternate feed materials.
