INTRODUCTION This report is being submitted by Energy Fuels Resources (USA) Inc. ("EFRI"), licensee of the White Mesa Uranium Mill (the "Mill") to the Utah Division of Radiation Control ("DRC") in compliance with condition 9.4D of State of Utah Radioactive Materials License No. UT 1900479 (the "License"). There was one Safety and Environmental Review Panel ("SERP") evaluation conducted for the period of January 1, 2014 through December 31, 2014. The SERP evaluation and review was conducted in accordance with SERP procedures set forth in the Mill's Standard Operating Procedure PBL-1, Rev. No. R-6 (the "SERP SOP"). The evaluation is summarized below in Section 2. 2. SUMMARY OF EVALUATIONS This section describes the change, test, or experiment evaluated by the SERP pursuant to License condition 9.4, and summarizes the evaluations performed and actions taken by the SERP relative to each. In each case, the SERP consisted of those individuals specified in License condition 9.4 C, with additional members included as appropriate, to address specific technical issues. The SERP followed the SERP SOP as it performed its evaluations, to ensure that the actions taken satisfy the following three conditions specified in License condition 9.4 B: a) The change, test or experiment does not conflict with any requirement specifically stated in the License, or impair the licensee's ability to meet all applicable regulations. b) There is no degradation in the essential safety or environmental commitments in the License application or provided by the approved reclamation plan. c) The change, test or experiment is consistent with the conclusions of actions analyzed and selected in the Environmental Assessment dated February 1997 (the "1997 Environmental Assessment). 2.1. SERP Report No. 2014-01 December 18, 2014 KOH Process SOP 2.1.1. Proposed Action Review and approve revisions (the "KOH Process Change") to the existing Standard Operating Procedure ("SOP" or "Procedure") for processing Honeywell, (formerly known as Allied Signal Corporation, Metropolis Illinois) alternate feed materials. 2.1.2. Descriptions of Change. Tests or Experiments 2 The Mill has an existing License amendment to process KOH alternate feed materials from Honeywell, (formerly known as Allied Signal Corporation, Metropolis Illinois), and proposes to modify the recovery process. The Mill has previously processed KOH alternate feed materials through the addition of water to the drums manually, by Mill personnel, prior to dumping. The previous leach process used this water leach process 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 process 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 through the submerged dumping station and to produce higher uranium recoveries and require the use of less water and fewer reagents, specifically the ammonium sulfate reagent, than the process approved in the previous SOP. 2.1.3 Safety and Environmental Evaluation of this SERP Action The SERP reviewed the Procedure described above and determined that: a) 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 processes. b) 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 chemical reactions or off-gasses associated with processing KOH under the SOP, as amended by the Change, that haven't been experienced and handled safely by the Mill in connection with processing other alternate feed materials. Specifically, the KOH SOP has been modified to introduce the material while submerged, eliminating any dust. c) There are no changes proposed to the storage, or washing steps of KOH processing. The leached and washed process liquids containing uranium will be transferred to the existing SX, precipitation, drying and packaging areas with no modifications required. d) 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 KOH Process Change. e) There would be no increase in environmental emissions 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. 2.1.4 SERP Action The SERP concluded that: a) The KOH SOP, as amended by the KOH Process Change, does not conflict with any requirements specifically stated in the license, or impair EFRTs ability to meet all applicable regulations. The material to be processed is already covered by an existing license amendment and has previously been processed according to the conditions of the license amendment. The Mill has remained in compliance with the License and other regulatory requirements while running a comparable process, and fully expects to remain in compliance with the same requirements when running the revised process. b) The KOH Process Change will not produce any degradation in the essential safety or environmental commitments in the License application, or provided by the approved reclamation plan. The KOH Process Change involves a feed already processed previously at the Mill, and involves no new reagents, chemical or radiological hazards or environmental emissions. c) The KOH Process Change will have no effect on the Reclamation Plan. The volumes of solutions and solid tailings that would be transferred to tailings would be the same whether the KOH Material were processed by the existing SOP or the proposed Change to the SOP. It would have no effect on the volume or nature of tailings. d) The Yellowcake recovered from the KOH alternate feed material will not cause the Mill to exceed the yellowcake production limit under the Mills license. e) The KOH 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 The SERP concluded that the Procedure meets the criteria set forth in the SERP SOP for approval, and approved the revised KOH Procedure. 4
