Energy Fuels Resources (USA) Inc. 225 Union Blvd. Suite 600 Lakewood, CO, US, 80228 303 974 2140 DRC-2014-006782 www.energyfuels.com VIA EMAIL AND OVERNIGHT DELIVERY November 18, 2014 Mr. Rusty Lundberg Division of Radiation Control Utah Department of Environmental Quality 195 North 1950 West P.O. Box 144850 Salt Lake City, UT 84114-4820 Re: Energy Fuels Resources (USA) Inc. Response to Division of Radiation Control ("DRC") Request for Information letter dated October 14, 2014 and e-mail Request for Revision dated October 20, 2014 for the Environmental Protection Manual ("EPM"),White Mesa Uranium Mill - RML UT1900479 Dear Mr. Lundberg: This letter responds to the Division of Radiation Control's ("DRC's") Request for Information ("RFI") dated October 14, 2014 and the DRC's Request for Revision dated October 20, 2014, regarding Energy Fuels Resources (USA) Inc.'s. ("EFRI's") September 8, 2014 Environmental Protection Manual revisions submitted as required by License Condition 11.9. This letter addresses the comments from the RFI and Request for Revision. For ease of review, each of DRC's comments is provided verbatim below in italics, followed by EFRI's response. The White Mesa Mill EPM is comprised of fifteen separate Standard Operating Procedures ("SOPs") or Plans, housed in one binder. Only those SOPs which require revision are attached to this response letter in Attachment A. It is important to note that additional changes to correct typographical errors or to update procedures are also included for completeness purposes only, and were not made to respond to the RFI and Request for Revision. The redline strikeout changes from the September 8, 2014 submission have been accepted for incorporation. The changes resulting from the October 14, 2014 RFI and from the October 20, 2014 Request for Revision are shown in redline text for your convenience. Implementation of the changes described in these SOPs will commence on the next routine sample period after the receipt of DRC approval of the EPM, that is, on the next routinely scheduled quarterly or annual sampling event unless DRC specifies otherwise. Letter to Rusty Lundberg November 18,2014 Page 2 of 7 Comments from DRC RFI dated October 14, 2014 DRC Comment: EFRI Standard Operating Procedure (SOP): Air Monitoring-P articulate Radionuclides Part II Standard Operating Procedures 1.0 Equipment It states; "Particulates are trapped on an 8 X 10-inch glass micro fiber filter... " RFI Question # I: What is the micron size of the filters used for air particulate monitoring? EFRI Response: EFRI is currently using the Whatman EPM 2000, with a pore size of the filters is 2.5 iim ("microns") and with a >99.95% efficiency for 0.3um-size particles. The EPM 2000 has been selected by U.S. EPA as standard filter used in nationwide high-volume air sampler network. EPA requires a "Collection efficiency: 99 percent minimum as measured by the DOP test (ASTM-2986) for particles of 0.3 urn diameter. These specifications have not been added to the SOP as it is not necessary for the completion of field activities. The SOP has been modified to remove the EPM 1000 filter because it is no longer manufactured and has been replaced with the EPM 2000. DRC Comment: EFRI Standard Operating Procedure (SOP): Air Monitoring-P articulate Radionuclides Part 11 Standard Operating Procedures 3.1 Orifice Plate It states; "The orifice plates shall be calibrated every year as recommended by the EPA. A certified calibration laboratory that will use the EPA or an EPA-approved method..." RFI Question #2: What is the EPA or approved EPA method used to calibrate the orifice plate? EFRI Response: The EPA methods used for orifice calibrations are as specified in 40CFR Part 50, Appendix B, Section 9.2.17. Specifically, the methods delineated in EPA-600/4-77-027a, The Quality Assurance Handbook for Air Pollution Measurement Systems, Volume II - Ambient Air Specific Methods. Copies of the pertinent pages have been included as Attachment B to this response. Letter to Rusty Lundberg November 18, 2014 Page 3 of 7 The SOP has been modified to include the appropriate reference to the EPA method. DRC Comment: EFRI SOP: Surface Soil Monitoring 1.0 Soil Monitoring lt states; "Soil samples from the northern Mill boundary and the north half of the eastern boundary (adjacent to section 22, 27 and 34) are collected approximately every 1000 feet. The remainder of the perimeter boundary soil samples are collected every 2500 feet." However, on page 2 EFRI Response: states: The additional samples will be collected at a frequency of every 500feet along the northern mill boundary. Please correct the inconsistency. EFRI Response: The soil samples from the northern Mill boundary and the north half of the eastern boundary (adjacent to section 22, 27 and 34) will be collected approximately every 1000 feet. The EFRI response referenced in the comment was incorrect. Since the SOP is correct, no changes to the SOP are required. DRC Comment: EFRI SOP: Surface Soil Monitoring 1.0 Soil Monitoring RFI Question #3: How will the soil sample locations be marked? EFRI Response: Each soil sampling location will be marked with an aluminum tag with the sample location identification etched or painted on the tag. The tags will be attached to a metal stake driven approximately 18 inches into the ground. The marking procedure noted above has been added to the SOP. DRC Comment: EFRI SOP: Surface Soil Monitoring 1.0 Soil Monitoring RFI Question #4: Please describe how the soil sampling locations will be protected to keep the sampling area undisturbed? Letter to Rusty Lundberg November 18, 2014 Page 4 of 7 EFRI Response: The sampling locations will be placed on the inside of the Mill's perimeter fence to reduce the chances of tampering and vandalism. The locations will be sited approximately one foot from the inside of the perimeter fence to prevent inadvertent disturbance by truck or vehicle traffic. The location markers will be designed and installed with as low a profile as possible, while still maintaining visibility for ease of location during the annual sampling program. It is important to note that the Mill's perimeter fence was recently replaced and there are no immediate plans for construction or maintenance activities of the fence thus limiting the potential for disturbance from Mill Staff. DRC Comment: 3.0 Analytical Requirements RFI Question #5 Please add Th-232 and Pb-210 to the analytical requirements for soil samples based on receipt and processing of alternate feeds. EFRI Response. While not required by NRC Regulatory Guideline 4.14, Th-232 and Pb-210 have been added to the analytical suite for the annual soil sampling program. The SOP has been modified as requested. DRC Comment: Vegetation Sampling RFI Questions RFI Question #6 Explain the rational of only having three areas for vegetation sampling? EFRI Response: The current program is appropriate for assessing impacts from Mill activities because the locations currently sampled are on the property boundaries or just outside of the property boundaries which represent the areas of potential impact from Mill activities. Because the current sample locations are on or within the Mill boundaries, they will indicate whether any contamination has left the property boundary. The three locations for vegetation sampling represent the areas most likely to be impacted by Mill activities based on prevailing wind directions. The predominant wind direction during the 2004 - 2013 period were from the north-northwest through north-northeast approximately 35% of the time. The southwest vegetation sampling location was placed to assess impacts in this area. The secondary wind Letter to Rusty Lundberg November 18, 2014 Page 5 of 7 direction pattern from the south through the south-southwest occurred 18.2% of the time. The northwest and northeast vegetation sampling locations were placed to assess impacts in this direction. The three vegetation sampling areas are sited such that impacts from Mill activities would be detected in these locations and would indicate if any contamination has left the property. The vegetation sampling locations are close to the Mill process areas by design to assess Mill impacts. It is important to note that all three locations are sampled three times per year resulting in nine data points annually. In addition, a large volume of vegetation is required to complete the analyses specified; approximately 20 kilograms of vegetation is collected for each sample at each location. The vegetation volume for each location fills a large 39-gallon trash bag. Vegetation in the area is sparse due to the dessert-like ecosystem and recent drought conditions have worsened the vegetation conditions. Collecting more locations on the same schedule would have an adverse impact on the ecosystem and overall environment in the area. DRC Comment: Vegetation Sampling RFI Questions RFI Question #7 Explain what type of vegetation is sampled? EFRI Response: As previously stated, vegetation in the area is sparse due to the dessert-like ecosystem. Primarily, vegetation samples are composed of sage brush, rabbit brush, native grasses and cactus. Some variability in the sample composition is based on the time of year the sampling is conducted. The three sampling events are conducted in early spring, late spring and late fall. The time of year impacts what plants are available for collection with less grass available during the fall sampling event. DRC Comment: Vegetation Sampling RFI Questions RFI Question #8 Please add U-Nat and Th-232, to the analytical requirements [for vegetation] based on receipt and processing of alternate feeds. EFRI Response: While not required by NRC Regulatory Guideline 4.14, Th-232 and U-Nat have been added to the analytical suite for the vegetation sampling program. The SOP has been modified as requested. Letter to Rusty Lundberg November 18, 2014 Page 6 of 7 DRC Comment: Air Monitoring - Radon Monitoring Plan Please add at the end of section 1.1 that all detector results will be provided in the Semi-annual Environmental [Effluent] report. EFRI Response: The SOP has been modified as requested.

Turk Scott Bakken Attachments ATTACHMENT A REDLINE White Mesa Mill - Standard Operating Procedures I Book #11, Environmental Protection Manual, Section 1.2 Date: G4JL1/14 Revision: EFR-32- l Page 1 of 3 AIR MONITORING ~ RADON 1. RADON MONITORING PLAN 1.1 Locations and Frequency of Samples Radon samples are taken at the following locations: BHV-1 BHV-2 BHV-2A (Duplicate of BHV-2) BHV-3 (Background location for use in assessment of background concentrations) BHV-4 BHV-5 BHV-6 BHV-7 BHV-8 BHV-70 (Blank sample for use in assessment of effects due to sample shipment. Previously numbered as BHV-7) See Attachment A to Section 1.1 of this Environmental Protection Manual for the locations of these monitoring stations. Samples are collected on a quarterly basis using Radtrak® (Trac-Etch) Outdoor Air | Radon Detector, (Landauer Part Number DRNM) or equivalent. One or more than 4one Radtrak® (Trac-Etch) Outdoor Air Radon Detector will be placed at each of the locations noted above (except BHV-70). The number of detectors to be placed at each location | shall be as determined by the Radiation ASafety Officer ("RSO"). If multiple Radtrak® detectors are placed at one location, the numeric average of the results for that location will be calculated and reported as the radon value for the quarter. Radtrak® (Trac-Etch) detector results will be reported in the Semi-Annual Effluent Report. 1.2 Quality Assurance Quality assurance of the samples is met by collecting samples in accordance with the conditions and guidelines set forth in Section 2 of this procedure. In addition, the following steps will be followed: a) One duplicate sample or set of duplicate samples will be collected each quarter by placing samples at the same location as the routine sample(s), at the same height as the routine sample(s), and as close to the routine sample(s) as reasonably achievable; I White Mesa Mill - Standard Operating Procedures Date: 0411/14 Revision: EFR-32- Book #11, Environmental Protection Manual, Section 1.2 Page 2 of 3 b) A field blank sample will be collected each quarter to assess any concentrations resulting from shipment of the detectors; c) Detector locations will be monitored periodically to ensure the detectors have not been lost; d) Detector shipments will be inspected to ensure that all detectors are present when receiving or shipping detectors; and e) Monitoring data will be reviewed for consistency and data transportation issues/detections. 1.3 Analytical Requirements Each quarterly sample will be analyzed for Radon-222. Results will be expressed in pCi/L. 2. STANDARD OPERATING PROCEDURES 2.1 Equipment Samples will be collected using the Radtrak® (Trac-Etch) Outdoor Air Radon Detector (Landauer Part Number DRNM) or equivalent. The detectors will be returned to the supplier/manufacturer for processing and analysis. Detectors are analyzed using the "high sensitivity" methodology, which provides a lower limit of detection of 6.0 pCi/L- days. 2.2 Monitoring Methodology The following monitoring procedures will be followed: a) Remove detector from package - The Radtrak® radon detectors are supplied in aluminum bags which prevent radon exposure. Open the aluminum bag and remove the clear plastic cup which has a Radtrak® detector fastened to the bottom. Detectors, before, during or after exposure should not be in locations which exceed a temperature of 160°F (70°C). There is no low temperature. b) Fill in the enclosed Detector Log Sheet with the serial number on the detector label. Also fill in the date installed and the location information in the location/comments area. c) Attach a field canister to a post or other location using the metal bracket with the open mouth of the canister facing down. The canister may be placed at any desired height (typically 3-6 feet) and preferably in a location minimizing animal damage or tampering. Remove the clear acrylic retaining ring from the canister by removing the wing nuts. Install the assembled cup inside the canister and replace the retaining ring and wing nuts in order to hold the cup in place. I White Mesa Mill - Standard Operating Procedures Date: 04U./14 Revision: EFR-32- Book #11, Environmental Protection Manual, Section 1.2 Page 3 of 3 d) Leave the detectors undisturbed for the duration of the three month monitoring period. e) At the end of the monitoring period, remove the Radtrak® detector from the plastic cup. Peel off the gold seal provided with the shipment and cover all the holes on the top of the detector. This stops the monitoring period. Record the ending date on the Detector Log Sheet. f) After all of the detectors have been collected and sealed, but prior to final packaging and shipment, open a new detector and immediately cover all the holes on the top of the detector with one of the gold seals provided with the shipment. Label this detector as BHV-70 on the Detector Log Sheet. Use the same exposure time/days for BHV-70 as the eight sample detectors when listing BHV-70 on the Detector Log Sheet. g) Return the detectors along with a copy of the Detector Log Sheet using the laboratory provided label for shipment back to the supplying organization. 3. RECORD KEEPING Data maintained in record form for environmental radon is: a) Sample period; b) Sample location; and c) Radon levels. White Mesa Mill - Standard Operating Procedures Book #11: Environmental Protection Manual, Section 1.4 Date: 43/43-1 l/14Revision: EFR-43 Page 1 of 6 STACK EMISSION MONITORING PROCEDURES WHITE MESA GAS STACK EMISSIONS 1.0 INTRODUCTION White Mesa, or it's contracted service providers, uses scientifically approved reference methods to determine gas stack emissions release concentration for radionuclide particulates. These methods conform to principles that apply to obtaining valid samples of airborne radioactive materials, using prescribed acceptable methods and materials for gas and particulate sampling. See American Standard Guide to Sampling Airborne Radioactive Materials in Nuclear Facilities ANSI N13.1-1969. These sampling methods are also consistent with guidance contained in the U.S. Nuclear Regulatory Commission's Regulatory Guide 4.14, "Radiological Effluent and Environmental Monitoring at Uranium Mills." 2.0 SAMPLING METHODOLOGIES The sampling methods for airborne radionuclide particulates, from the yellowcake dryer and other mill effluent control stacks, are identical to methods published in the EPA's manual, Gas Stream Sampling Reference Methods for New Source Performance Standards; they are found in the EPA Manual in Appendix No. 5. "Determination of Particulate Emissions from Stationary Sources" ("EPA Method #5") and Appendix No. 17, "Determination of Particulate Emissions from Stationary Sources (In-Stack Filtration Method)" ("EPA Method #17). Copies of EPA Method #5 and #17 are attached to this SOP. Sampling is performed as per the methods, to ensure that the sampling and results are: (1) isokinetic; (2) representative; and (3) adequate for determination of the release rates and concentrations of U-Nat, Th-230, Ra-226 and Pb-210. 2.1 Sampling Equipment Sampling equipment used to collect airborne radionuclide particulates from point source emission stacks at the Mill consists of equipment manufactured by Research Appliance Company (RAC), (or other equivalent apparatuses), as follows: 1. RAC Model 201009 Model 2414 stack sampler. 2. Two each, RAC Model 201044 modular sample cases. One heater box and one glassware box. 3. One each, RAC Model 201019 umbilical cord.

Three each, RAC Model 201013 - 100mm diameter filter holders. 5. One each, RAC Model 201005 standard pilot tube, three feet length, stainless steel/S-type probe. 6. Barometer. 7. Psychrometer. 8. Satorius Model 2432 balance or equivalent. 9. Triple beam balance. Equipment instruction and operating manual(s) provided by the manufacturer(s) are retained at the Mill and used for specific guidance and reference. 2.2 Sample Collection Gas stack samples are collected from emission control systems used in Uranium Recovery Operations at the Mill. These samples are collected from process stacks when the emission control systems are operating. They are sampled for radionuclide particulate concentrations at a frequency in accordance with Table 5- 1. Sample collection methods are described in detail in EPA Method #5 and EPA Method #17, Determination of Particulate Matter Emissions From Stationary Sources. It is necessary to read and understand all procedures described in the methods and in the equipment manual. The operation of the equipment requires "hands-on" instruction from the Environment Departmental Staff from individuals who are experienced in using sample collection equipment and applying sample collection methods. The following steps are described for stack sample collection. 1. Check equipment listed in Section 2.1 of this SOP. Consult the manufacturers equipment operations manual for details. 2. Assemble equipment as described in the operations manual for sample collection EPA Method #17. 3. Follow the calibration procedure listed in the manual. If the calibration measurements are not obtained, consult the trouble shooting section of the manual for corrective instruction. Once the collection apparatus is calibrated, proceed to the next step. 4. Weigh a new glass fiber filter, record the weight, and place in the filter holder assembly. 5. Check the sample collection system for leaks. 6. Cap ends of sample probes to prevent contamination and transport sample unit to the sample location. 7. Uncap sample end and insert 3/8-diameter sample probe into the stack in the midsection of the exhaust stream. 8. Turn sample apparatus on and observe unit operation to insure a sample is being collected and the apparatus is functioning properly.

Collect the stack sample for at least one hour during periods of routine process operation. Note the collection time. 10. Record the information described in the manufacture's operations manual. This information is also described in the EPA Methods #5 and #17 for point source particulate emissions. 11. After sample collection is complete, turn off unit. Obtain sample filter from filter housing and place in a new plastic petri dish. Send to outside laboratory for radionuclide analysis in accordance with Table 5-1. 2.3 Sample Handling and Shipping 1. During preparation and assembly on the sampling train, keep all openings where contamination can occur covered until just prior to assembly or until sampling is about to begin. 2. Using a tweezer or clean disposable surgical gloves, place a labeled (identified) and weighed filter in the filter holder. Be sure that the filter is properly centered and the gasket properly placed so as to prevent the sample gas stream from circumventing the filter. Check the filter for tears after assembly is completed. 3. Before moving the sampling train to the cleanup site, remove the probe from the sample train, wipe off the silicone grease, and cap the open outlet of the probe. Be careful not to lose any condensate that might be present. Wipe off the silicone grease from the filter inlet where the probe was fastened, and cap it. Remove the umbilical cord from the last impinger, and cap the impinger. If a flexible line is used between the first impinger or condenser and the filter holder, disconnect the line at the filter holder, and let any condensed water or liquid drain into the impingers or condenser. After wiping off the silicone grease, cap off the filter holder outlet and impinger inlet. Either ground-glass stoppers, plastic caps, or serum caps may be used to close these openings. 4. Transfer the probe and filter-impinger assembly to the cleanup area. This area should be clean and protected from the wind so that the chances of contaminating or losing the sample will be minimized. 5. Save a portion of the acetone used for cleanup as a blank. Take 200 ml of this acetone directly from the wash bottle being used, and place it in a glass sample container labeled "acetone blank." 6. Carefully remove the filter from the filter holder, and place it in its identified petri dish container. Use a pair of tweezers and/or clean disposable surgical gloves to handle the filter. If it is necessary to fold the filter, do so such that the PM cake is inside the fold. Using a dry Nylon bristle brush and/or a sharp-edged blade, carefully transfer to N:\WMM\SOPs and ProceduresVEPM - November 2014 RevisionVSection 1.4 Stack MonitoringVAppendix E-Section 1.4 Stack Emission 4 - Nov 2014.docF:\Mill SOP Maoter Copv\Book 11 Environmental Procedure5\07 License RcncwalVEFRVAppendix E Section 1.1 StQckEmission3.doc White Mesa Mill - Standard Operating Procedures Book #11: Environmental Protection Manual, Section 1.4 Date: 43/43-1 l/14Revision: EFR-43 Page 4 of 6 the petri dish and PM and/or filter fibers that adhere to the filter holder gasket. Seal the container. 7. Send to the laboratory for radionuclide analysis. 3.0 RECORD KEEPING Records of gas stack effluent sampling events and results of analysis are retained at the Mill. The following information is recorded: 1. Stack and Run ID 2. Date and Sampler 3. Sampled Air Volume at standard conditions 4. Sampled Water Volume at standard conditions 5. Moisture Content (volume basis) 6. Stack Gas Molecular Weight (wet basis) 7. Stack Gas Velocity 8. Stack Gas Volumetric Flow Rate (dry basis, at standard conditions) 9. Particulate Concentration 10. Percent Isokinetics 11. Emission Rates for Particulates U-Nat, Th-230, Ra-226, and Pb-210. The data are used to calculate emission rates in pounds and pico curies per hour for radionuclide particulate concentrations. 4.0 MONITORING LOCATION AND FREQUENCY Stack sampling must be performed during any quarter or semi-annual period that the stacks operate in accordance with the schedule in Table 5-1. During non- operational periods, stack sampling is not performed. 4.1 Yellowcake Stacks The exhaust stack for the drying and packaging equipment associated with the yellowcake calciner is sampled on a quarterly basis during operations. The sample ports are located on the roof of the main Mill building. 4.2 Feed Stacks The grizzly feed stack is located on the north end of the grizzly structure. This stack is accessible from a stack platform and is sampled on a semi annualquarterly basis if this system is operating.

Calibration of equipment is checked on a periodic basis. Probe tips are protected by a protective cap while not in use to protect accuracy determinations. During transport of equipment, all openings are sealed to prevent contamination. Calculations utilized during runs to maintain isokinetic conditions are reviewed and dry run tested prior to the actual run. All containers and probes are washed prior to each usage. Malfunction of sampling equipment, excessive malfunctions of normal operations being monitored, or percent isokinetic sampling rates greater than ± 10% error, indicate mandatory voiding of the run or data involved. 6.2 Operations If samples are collected from the operation of any unit which appears, in the judgment of the sampler, to be functioning in a manner not consistent with normal operations, then the sample will be voided and the system will be resampled. 6.3 Chemical Sample Control Analyses on each period's sample shall include blanks for the filters, impinger solutions, and the rinse solutions. A field logbook shall be maintained listing data generated, determinations of volumes measured, and net gain weights of filters to provide a back up to summary data records. Filters are transmitted within plastic enclosed petri dishes. Handling of filters is only done using tweezers. 6.4 Calculations All calculations will be retained at the Mill in both a hard copy and computer files. The gas stack effluent concentrations (C) are calculated as follows: Lab Result uCi (A) / Volume Sampled (V) = Effluent Concentration (C) where Volume Sampled (V) = Flow rate (Q) * Time of sample collection in minutes (t) and Lab Result uCi (A) = Radioisotopic activity, in uCi on air filter N:\WMM\SOPs and Procedures\EPM - November 2014 Revision\Section 1.4 Stack MonitoringVAppendix E-Section 1.4 Stack Emission 4 - Nov 2014.docF:\Mill SOP Master CopyVBook 11 Environmental Procodurcs\07 License Renewal\EFR\Appendix E Section 1.4 Stack Emission 3.doc I White Mesa Mill - Standard Operating Procedures Book #11: Environmental Protection Manual, Section 1.4 i Date: 43/43-JJ/14Revision: EFR-43 Page 7 of 6 N:\WMM\SOPs and Procedures\EPM - November 2014 RevisiorASection 1.4 Stack MonitorineVAppendix E-Section 1.4 Stack Emission 4 - Nov 2014.docF:\Mill SOP Master CopyVBook 11 Environmental Procedures\07 License Rencwal\EFR\Appendix E Section 1.4 Stack Emission 3.doc BHV-2 * V I J v?

RADON MONITORING PLAN 1.1 Locations and Frequency of Samples Radon samples are taken at the following locations: BHV-1 BHV-2 BHV-2A (Duplicate of BHV-2) BHV-3 (Background location for use in assessment of background concentrations) BHV-4 BHV-5 BHV-6 BHV-7 BHV-8 BHV-70 (Blank sample for use in assessment of effects due to sample shipment. Previously numbered as BHV-7) See Attachment A to Section 1.1 of this Environmental Protection Manual for the locations of these monitoring stations. Samples are collected on a quarterly basis using Radtrak® (Trac-Etch) Outdoor Air | Radon Detector, (Landauer Part Number DRNM) or equivalent. One or more than 4one Radtrak® (Trac-Etch) Outdoor Air Radon Detector will be placed at each of the locations noted above (except BHV-70). The number of detectors to be placed at each location | shall be as determined by the Radiation ASafety Officer ("RSO"). If multiple Radtrak® detectors are placed at one location, the numeric average of the results for that location will be calculated and reported as the radon value for the quarter. Radtrak® (Trac-Etch) detector results will be reported in the Semi-Annual Effluent Report. 1.2 Quality Assurance Quality assurance of the samples is met by collecting samples in accordance with the conditions and guidelines set forth in Section 2 of this procedure. In addition, the following steps will be followed: a) One duplicate sample or set of duplicate samples will be collected each quarter by placing samples at the same location as the routine sample(s), at the same height as the routine sample(s), and as close to the routine sample(s) as reasonably achievable; White Mesa Mill - Standard Operating Procedures Date: 0411714 Revision: EFR-32 Book #11, Environmental Protection Manual, Section 1.2 Page 2 of 3 b) A field blank sample will be collected each quarter to assess any concentrations resulting from shipment of the detectors; c) Detector locations will be monitored periodically to ensure the detectors have not been lost; d) Detector shipments will be inspected to ensure that all detectors are present when receiving or shipping detectors; and e) Monitoring data will be reviewed for consistency and data transportation issues/detections. 1.3 Analytical Requirements Each quarterly sample will be analyzed for Radon-222. Results will be expressed in pCi/L. 2. STANDARD OPERATING PROCEDURES 2.1 Equipment Samples will be collected using the Radtrak® (Trac-Etch) Outdoor Air Radon Detector (Landauer Part Number DRNM) or equivalent. The detectors will be returned to the supplier/manufacturer for processing and analysis. Detectors are analyzed using the "high sensitivity" methodology, which provides a lower limit of detection of 6.0 pCi/L- days. 2.2 Monitoring Methodology The following monitoring procedures will be followed: a) Remove detector from package - The Radtrak® radon detectors are supplied in aluminum bags which prevent radon exposure. Open the aluminum bag and remove the clear plastic cup which has a Radtrak® detector fastened to the bottom. Detectors, before, during or after exposure should not be in locations which exceed a temperature of 160°F (70°C). There is no low temperature. b) Fill in the enclosed Detector Log Sheet with the serial number on the detector label. Also fill in the date installed and the location information in the location/comments area. c) Attach a field canister to a post or other location using the metal bracket with the open mouth of the canister facing down. The canister may be placed at any desired height (typically 3-6 feet) and preferably in a location minimizing animal damage or tampering. Remove the clear acrylic retaining ring from the canister by removing the wing nuts. Install the assembled cup inside the canister and replace the retaining ring and wing nuts in order to hold the cup in place. I White Mesa Mill - Standard Operating Procedures I Book #11, Environmental Protection Manual, Section 1.2 Date: 04JJ./14 Revision: EFR-32- > Page 3 of 3 d) Leave the detectors undisturbed for the duration of the three month monitoring period. e) At the end of the monitoring period, remove the Radtrak® detector from the plastic cup. Peel off the gold seal provided with the shipment and cover all the holes on the top of the detector. This stops the monitoring period. Record the ending date on the Detector Log Sheet. f) After all of the detectors have been collected and sealed, but prior to final packaging and shipment, open a new detector and immediately cover all the holes on the top of the detector with one of the gold seals provided with the shipment. Label this detector as BHV-70 on the Detector Log Sheet. Use the same exposure time/days for BHV-70 as the eight sample detectors when listing BHV-70 on the Detector Log Sheet. g) Return the detectors along with a copy of the Detector Log Sheet using the laboratory provided label for shipment back to the supplying organization. 3. RECORD KEEPING Data maintained in record form for environmental radon is: a) Sample period; b) Sample location; and c) Radon levels.

These methods conform to principles that apply to obtaining valid samples of airborne radioactive materials, using prescribed acceptable methods and materials for gas and particulate sampling. See American Standard Guide to Sampling Airborne Radioactive Materials in Nuclear Facilities ANSI N13.1-1969. These sampling methods are also consistent with guidance contained in the U.S. Nuclear Regulatory Commission's Regulatory Guide 4.14, "Radiological Effluent and Environmental Monitoring at Uranium Mills." 2.0 SAMPLING METHODOLOGIES The sampling methods for airborne radionuclide particulates, from the yellowcake dryer and other mill effluent control stacks, are identical to methods published in the EPA's manual, Gas Stream Sampling Reference Methods for New Source Performance Standards; they are found in the EPA Manual in Appendix No. 5, "Determination of Particulate Emissions from Stationary Sources" ("EPA Method #5") and Appendix No. 17, "Determination of Particulate Emissions from Stationary Sources (In-Stack Filtration Method)" ("EPA Method #17). Copies of EPA Method #5 and #17 are attached to this SOP. Sampling is performed as per the methods, to ensure that the sampling and results are: (1) isokinetic; (2) representative; and (3) adequate for determination of the release rates and concentrations of U-Nat, Th-230, Ra-226 and Pb-210. 2.1 Sampling Equipment Sampling equipment used to collect airborne radionuclide particulates from point source emission stacks at the Mill consists of equipment manufactured by Research Appliance Company (RAC), (or other equivalent apparatuses), as follows: 1. RAC Model 201009 Model 2414 stack sampler. 2. Two each, RAC Model 201044 modular sample cases. One heater box and one glassware box. 3. One each, RAC Model 201019 umbilical cord.

Three each, RAC Model 201013 - 100mm diameter filter holders. 5. One each, RAC Model 201005 standard pilot tube, three feet length, stainless steel/S-type probe. 6. Barometer. 7. Psychrometer. 8. Satorius Model 2432 balance or equivalent. 9. Triple beam balance. Equipment instruction and operating manual(s) provided by the manufacturer(s) are retained at the Mill and used for specific guidance and reference. 2.2 Sample Collection Gas stack samples are collected from emission control systems used in Uranium Recovery Operations at the Mill. These samples are collected from process stacks when the emission control systems are operating. They are sampled for radionuclide particulate concentrations at a frequency in accordance with Table 5- 1. Sample collection methods are described in detail in EPA Method #5 and EPA Method #17, Determination of Particulate Matter Emissions From Stationary Sources. It is necessary to read and understand all procedures described in the methods and in the equipment manual. The operation of the equipment requires "hands-on" instruction from the Environment Departmental Staff from individuals who are experienced in using sample collection equipment and applying sample collection methods. The following steps are described for stack sample collection. 1. Check equipment listed in Section 2.1 of this SOP. Consult the manufacturers equipment operations manual for details. 2. Assemble equipment as described in the operations manual for sample collection EPA Method #17. 3. Follow the calibration procedure listed in the manual. If the calibration measurements are not obtained, consult the trouble shooting section of the manual for corrective instruction. Once the collection apparatus is calibrated, proceed to the next step. 4. Weigh a new glass fiber filter, record the weight, and place in the filter holder assembly. 5. Check the sample collection system for leaks. 6. Cap ends of sample probes to prevent contamination and transport sample unit to the sample location. 7. Uncap sample end and insert 3/8-diameter sample probe into the stack in the midsection of the exhaust stream. 8. Turn sample apparatus on and observe unit operation to insure a sample is being collected and the apparatus is functioning properly.

Collect the stack sample for at least one hour during periods of routine process operation. Note the collection time. 10. Record the information described in the manufacture's operations manual. This information is also described in the EPA Methods #5 and #17 for point source particulate emissions. 11. After sample collection is complete, turn off unit. Obtain sample filter from filter housing and place in a new plastic petri dish. Send to outside laboratory for radionuclide analysis in accordance with Table 5-1. 2.3 Sample Handling and Shipping 1. During preparation and assembly on the sampling train, keep all openings where contamination can occur covered until just prior to assembly or until sampling is about to begin. 2. Using a tweezer or clean disposable surgical gloves, place a labeled (identified) and weighed filter in the filter holder. Be sure that the filter is properly centered and the gasket properly placed so as to prevent the sample gas stream from circumventing the filter. Check the filter for tears after assembly is completed. 3. Before moving the sampling train to the cleanup site, remove the probe from the sample train, wipe off the silicone grease, and cap the open outlet of the probe. Be careful not to lose any condensate that might be present. Wipe off the silicone grease from the filter inlet where the probe was fastened, and cap it. Remove the umbilical cord from the last impinger, and cap the impinger. If a flexible line is used between the first impinger or condenser and the filter holder, disconnect the line at the filter holder, and let any condensed water or liquid drain into the impingers or condenser. After wiping off the silicone grease, cap off the filter holder outlet and impinger inlet. Either ground-glass stoppers, plastic caps, or serum caps may be used to close these openings. 4. Transfer the probe and filter-impinger assembly to the cleanup area. This area should be clean and protected from the wind so that the chances of contaminating or losing the sample will be minimized. 5. Save a portion of the acetone used for cleanup as a blank. Take 200 ml of this acetone directly from the wash bottle being used, and place it in a glass sample container labeled "acetone blank." 6. Carefully remove the filter from the filter holder, and place it in its identified petri dish container. Use a pair of tweezers and/or clean disposable surgical gloves to handle the filter. If it is necessary to fold the filter, do so such that the PM cake is inside the fold. Using a dry Nylon bristle brush and/or a sharp-edged blade, carefully transfer to N:\WMM\SOPs and Procedures\EPM - November 2014 RevisionYSection 1.4 Stack MonitoringVAppendix E-Section 1.4 Stack Emission 4 - Nov 2014.docF:VMill SOP Master Copv\Book 11 Environmental Procedurcs\07 License RenewalVEFRVAppendix E Section 1.-1 Stack Emission 3.doc White Mesa Mill - Standard Operating Procedures Book #11: Environmental Protection Manual, Section 1.4 Date: 43/43-11/14Revision: EFR-44 Page 4 of 6 the petri dish and PM and/or filter fibers that adhere to the filter holder gasket. Seal the container. 7. Send to the laboratory for radionuclide analysis. 3.0 RECORD KEEPING Records of gas stack effluent sampling events and results of analysis are retained at the Mill. The following information is recorded: 1. Stack and Run ID 2. Date and Sampler 3. Sampled Air Volume at standard conditions 4. Sampled Water Volume at standard conditions 5. Moisture Content (volume basis) 6. Stack Gas Molecular Weight (wet basis) 7. Stack Gas Velocity 8. Stack Gas Volumetric Flow Rate (dry basis, at standard conditions) 9. Particulate Concentration 10. Percent Isokinetics 11. Emission Rates for Particulates U-Nat, Th-230, Ra-226, and Pb-210. The data are used to calculate emission rates in pounds and pico curies per hour for radionuclide particulate concentrations. 4.0 MONITORING LOCATION AND FREQUENCY Stack sampling must be performed during any quarter or semi-annual period that the stacks operate in accordance with the schedule in Table 5-1. During non- operational periods, stack sampling is not performed. 4.1 Yellowcake Stacks The exhaust stack for the drying and packaging equipment associated with the yellowcake calciner is sampled on a quarterly basis during operations.

Calibration of equipment is checked on a periodic basis. Probe tips are protected by a protective cap while not in use to protect accuracy determinations. During transport of equipment, all openings are sealed to prevent contamination. Calculations utilized during runs to maintain isokinetic conditions are reviewed and dry run tested prior to the actual run. All containers and probes are washed prior to each usage. Malfunction of sampling equipment, excessive malfunctions of normal operations being monitored, or percent isokinetic sampling rates greater than ± 10% error, indicate mandatory voiding of the run or data involved. 6.2 Operations If samples are collected from the operation of any unit which appears, in the judgment of the sampler, to be functioning in a manner not consistent with normal operations, then the sample will be voided and the system will be resampled. 6.3 Chemical Sample Control Analyses on each period's sample shall include blanks for the filters, impinger solutions, and the rinse solutions. A field logbook shall be maintained listing data generated, determinations of volumes measured, and net gain weights of filters to provide a back up to summary data records. Filters are transmitted within plastic enclosed petri dishes. Handling of filters is only done using tweezers. 6.4 Calculations All calculations will be retained at the Mill in both a hard copy and computer files.

The sampling locations are shown in Figure 1. Soil samples from the northern Mill boundary and the north half of the eastern boundary (adjacent to Sections 22,27 and 34) are collected approximately every 1000 feet. The remainder of the perimeter boundary soil samples are collected every 2500 feet. Soil samples are taken once per year during August or as soon as possible thereafter, but no later than September 30 of the year. Each soil sampling location will be marked with an aluminum tag with the sample location identification etched or painted on the tag. The tags will be attached to a metal stake driven approximately 18 inches into the ground. The sampling locations will be placed on the inside of the Mill's perimeter fence to prevent tampering and vandalism. The locations will be sited approximately one foot from the inside of the perimeter fence to prevent inadvertent disturbance by truck or vehicle traffic. The location markers will be designed and installed with as low a profile as possible, while still maintaining visibility for ease of location during the annual sampling program. In addition, a soil sample could be taken from Westwater Creek, in the place of a water sample. However, a sediment (soil) sample would only be taken at Westwater Creek if water was not available. In the event that a soil sample is collected in place of a water sample for Westwater Creek, the sample should be analyzed for the same parameters as those called for in this SOP (Radium-226 and U-nat). Refer to SOP No. PBL-EP-3 for details regarding collection of a water sample from Westwater Creek. 2.0 SAMPLING AND ANALYTICAL QUALITY ASSURANCE The sample bags are marked for location identification and are submitted to the analytical laboratory accompanied by Chain-of-Custody forms. (Attachment A) Analytical quality assurance for soil monitoring is based on the contract laboratory's quality controls such as blanks, duplicates, and standard percentage recovery. The laboratory is committed to meet the LLD values for radionuclides contained in U.S. NRC Regulatory Guides 4.14 and 4.15 and will perform re-runs on all samples not meeting these limits. Appropriate laboratory control and quality assurance data will be provided by the contract laboratory, or equivalent, including LLD information. 3.0 ANALYTICAL REQUIREMENTS All soil samples will be analyzed, on a dry basis for the following radionuclides: Ra-226 Th- 232, Pb-210, and U-Nat. Analytical results will be reported in appropriate radiological units such as pico curies per gram or micro curies per kilogram.

BHV-2 Approximately 2.5 miles north of the Mill. BHV-4 Approximately 400 yards south of Cell No. 4. BHV-5 Approximately 100 yards south of the intersection of Highway 191 and the Mill access road. BHV-6 Approximately 0.5 miles south of BHV-5 along Highway 191. BHV-7 Approximately 0.8 miles south of BHV-1 along Highway 191. BHV-8 Approximately 0.6 miles west of BHV-1. Air samples are collected on a weekly basis. A composite of 13 weekly samples from each of the above locations is prepared to form a quarterly sample for each location. 2.0 QUALITY ASSURANCE Quality assurance of the samples is met by collecting samples in accordance with the conditions and guidelines set forth in this SOP (Section 6.0). Quality assurance of the analytical results is based on the contract laboratory's quality controls such as blanks, duplicates, and standard percent recovery. The laboratory will also follow U.S. EPA Guide SW-846 and U.S. NRC Regulatory Guides 4.14 and 4.15 when analyzing the air filter samples. The laboratory is cornmitted to meet the LLD values for radionuclides listed in these guidance documents, and will perform re-runs on all samples not meeting these limits. 3.0 ANALYTICAL REQUIREMENTS Each quarterly sample will be analyzed for U-Nat, Ra-226, Th-230, Pb-210 and Th-232. Results will be expressed in picocuries per milliliter (pCi/mL). White Mesa Mill - Standard Operating Procedures Book #11, Environmental Protection Manual, Section 1.1 Date: 11/14 Revision: EFR-5 Page 2 of 7 PART II STANDARD OPERATING PROCEDURES 1.0 EQUIPMENT The equipment used in monitoring levels of particulate radionuclides consists of high volume air samplers equipped with mass flow controllers and vacuum switch controlled timers. The samplers are capable of collecting air through the sample filter at a volumetric flow rate of approximately 40 standard cubic feet per minute (scfm). The mass flow controller varies the actual air flow rate as dictated by changing temperature, filter loading, and barometric pressure to maintain a constant standard air flow rate. The actual rate is read directly from the analog gauge located on the front panel. The timer is turned off when no vacuum exists in the system, i.e., when the motor/blower assembly is disconnected or otherwise malfunctions. Particulates are trapped on an 8 x 10-inch glass microfiber filter such as one of the following, or equivalent: 1. Whatman EPM 2000 2. Schliecher & Schuell #1 HV. 2.0 MONITORING METHODOLOGY The air samplers are mounted on towers approximately 2 meters above ground plane. The samplers run continuously except for calibration, mechanical or electrical failure, and maintenance down time. Target flow rate will be 36 scfm. Air filters are replaced weekly due to particulate loadings. Maximum filter use duration will be weekly unless weather conditions prohibit safe access to one or more of the air monitoring station locations. Each filter is stamped by the manufacturer with a unique number. The blank filters are weighed to the nearest 0.0001 gram using a Sartorius Model 2432 analytical balance or equivalent. The filters are kept in manila folders inside resealable plastic bags for support during transportation to the site. The tare weight is then recorded on each filter folder along with the location, filter number, start date, and start time. This information is then input into an analytical data file on the computer. When the sampled filters are collected in the field, the stop dates and times are entered on the folder. On return from the field, the filters are again weighed and the gross weights are recorded on the folders. The weights, stop dates, and stop times are then recorded into the analytical data file that is printed off and sent to the contract laboratory. Samples are collected continuously for approximately one week. The "loaded" filters are removed from the shut down samplers, folded, and placed in the folders in the plastic bags. If any part of the filter remains on the seal gasket, it is removed and added to the folder. The new filters are removed from their folders and placed on the vacuum head White Mesa Mill - Standard Operating Procedures Book#l 1, Environmental Protection Manual, Section 1.1 Date: 11/14 Revision: EFR-5 Page 3 of 7 with the filter holder frame tightened enough to seal, but not tight enough to rupture the filters. The samplers are then turned on. Each station's filters are composited on a quarterly basis (13 weeks) by the environmental staff. The samples are forwarded, along with an analytical sheet and Chain of Custody (COC) form (provided by the contract laboratory), to the contract laboratory in sealed plastic bags. 3.0 CALIBRATION 3.1 Orifice Plate The orifice plates shall be calibrated every year as recommended by the EPA. A certified calibration laboratory that will use the EPA or an EPA-approved method will do the calibration. Calibrations will be completed in accordance with EPA-600/4-77-027a, The Quality Assurance Handbook for Air Pollution Measurement Systems, Volume II - Ambient Air Specific Methods. Calibration records are kept in the environmental files. 3.2 Sampler Calibration of the equipment occurs during the first Monday of each month. If a non- scheduled motor replacement is necessary, the sampler is re-calibrated. An orifice plate assembly and U-tube manometer are used for monthly calibrations. The sampler flow rate is regulated to a standard air volume that is recorded on the field calibration sheet using 20°C. (298 K) and 29.2 inches (760 mm) of mercury as standard conditions. The top portion of the Monthly Calibration and Weekly Flow Check Worksheet (Attachment C) is completed for each air sampling station and retained in the files. The monthly calibration task involves the following: 1. Before visiting each monitoring location, the air temperature and barometric pressure are recorded. 2. The motors are replaced as required. The replacement motors are prepared at the Mill office. 3. A filter is placed within the orifice plate, and the orifice plate is secured on top of the vacuum head. 4. The orifice plate is connected to the U-tube manometer and the initial inches H20 is recorded and a flow rate calculated using the current field temperature and pressure. 5. The control screw is adjusted as necessary to advance or slow the vacuum motor to reach the desired flow rate. The final flow rate must be at least 32 scfm on the analog meter and reach 75% onstream time for the quarter to meet the required LLD for the radionuclide parameters. White Mesa Mill - Standard Operating Procedures Book #11, Environmental Protection Manual, Section 1.1 Date: 11/14 Revision: EFR-5 Page 4 of 7 4.0 CALCULATIONS Using inches of water from the U-tube, refer to the following subsections to perform the calculation of flow rate. Section 4.1 provides the equation used to compute the flow rate at field conditions, and (the "actual" flow rate [Qa]), in cubic meters per minute. Actual flow rate must be corrected to standard flow rate (Qs) using the flow rate equation in Section 4.2. The standard flow rate is then converted to standard cubic feet with the conversion equation in Section 4.3. 4.1 Orifice Equation Using the inches of water measurement, determined from the U-tube, the following equation is used to calculate the flow rate at field conditions: Where: Qa = Actual flow rate at field conditions (mVmin) m = Slope value from Qa portion of orifice calibration AH = Manometer reading (in. H20) Ta = Actual temperature (273 + °C = K) [from the meteorological station data (temperature readings) that are downloaded weekly] Pa = Actual atmospheric pressure (mmHg) [from the meteorological station data (barometric pressure readings) that are downloaded weekly] b = Intercept value from Qa portion of orifice calibration The constants m and b in the above equation are provided by the calibration laboratory for each specific calibrated orifice (Attachment D). Each orifice will have unique performance properties that relate to design; those measured performance properties are incorporated into the flow equation as specific constants. The flow equation demonstrates the relationship between measured vacuum pressure in inches of water to actual flow rate utilizing this device. White Mesa Mill - Standard Operating Procedures Book#l 1, Environmental Protection Manual, Section 1.1 Date: 11/14 Revision: EFR-5 Page 5 of 7 4.2 Standard Conditions Flow Rate Equation The flow rate at standard conditions is calculated by adjusting the field condition flow rate, calculated above, by the following equation: f r> ^ Qs = Qa T Where: Qs = Standard flow rate at standard conditions (mVmin) Qa = Actual flow rate at field conditions (mVmin) Ta = Actual temperature (273 + °C = K) Pa = Actual atmospheric pressure (mmHg) Ts = Standard temperature = 298 K Ps = Standard atmospheric pressure = 760 mmHg 4.3 Correction Equation To convert the standard flowrate, from cubic meters per minute to standard cubic feet per minute, use the following equation: a(*%J=35.315x0>;/J 5.0 RECORD KEEPING The records are kept on the filter folders and the field worksheets, which are retained in the environmental files in the environmental office and are also entered into the analytical data file on the computer after the data have been reviewed. The following information will be entered into the computer data file (see Attachment E): • Filter number • Start date • Stop date • Start time • Stop time • Starting manometer reading (AH) (in. H2O) • Stopping manometer reading (AH) (in. H20) • Weekly average temperature (Ta) (°C) • Weekly average pressure (Pa) (mmHg) • Tare filter weight (g) • Gross filter weight (g) White Mesa Mill - Standard Operating Procedures Book #11, Environmental Protection Manual, Section 1.1 Date 11/14 Revision: EFR-5 Page 6 of 7 The following information will be calculated by the computer file (see Attachment E): • Total time (min) • Average manometer reading (AH) (in. H^O) • Weekly average temperature (K) • Actual flow rate (Qa) (m3/min) • Standard flow rate (Qs) (m3/min) • Standard flow rate (Qs) (ft3/min) • Total standard volume (m3) • Net weight (mg) • Loading (mg/m3) • Percent onstream 6.0 QUALITY ASSURANCE 6.1 Installation and Removal of Filters Field methods to assure quality of air sample collection include the following: 1. Inspection of all new filters for aberrations and discarding damaged ones. 2. Maintaining seals on equipment connections. 3. Careful installation and removal of filters, retaining all abraded filter media. 4. Proper sequential handling of all filters. 5. Filters are inspected for fingerprint contamination by visual observation. 6.2 Sample Duration Maintenance of sample duration is assured by: 1. Installation of a vacuum-actuated timer which operates the timer only when the motor is running and pulling the minimum allowable vacuum. 2. Weekly monitoring of stations and inspecting wear on the motors and proper change-out at appropriate intervals (monthly). 6.3 Sample Flow Rate Quality assurance of each sampler's flow rate is accomplished by weekly readings of the sampler's flow characteristics using a manometer. Sampler pressure drop readings are measured on a weekly basis using a manometer and going through the monthly calibration steps. This value, along with average weekly temperature and pressure values from the site meteorological station, are used to determine weekly flow rate values. Monthly checks of flow controller operation and documentation thereof also provide quality assurance. Samplers are calibrated and checked at motor rotation intervals (monthly). White Mesa Mill - Standard Operating Procedures Book #11, Environmental Protection Manual, Section 1.1 Date: 11/14 Revision: EFR-5 Page 7 of 7 6.4 Calculations Calculations are checked on a random basis for inconsistencies, and such checks are documented. Upon retrieval of the data analytical sheet from the contract laboratory, the date of receipt is noted, along with the date of transcription is noted on the sample station log sheet with the transcriber's initials. The transcription of data is reviewed by another person in the Environmental Department to minimize transposition of numerical values. Calculation and data storage is by computer program. 6.5 Sampler Performance A record of sampler operation time versus total possible duration time is maintained as a flag against excessive equipment downtime. Sampler performance is reviewed monthly. 6.6 Quality Control Methodology Blanks are weighed each week and submitted alongside the actual filters.

RADON MONITORING PLAN 1.1 Locations and Frequency of Samples Radon samples are taken at the following locations: BHV-1 BHV-2 BHV-2A (Duplicate of BHV-2) BHV-3 (Background location for use in assessment of background concentrations) BHV-4 BHV-5 BHV-6 BHV-7 BHV-8 BHV-70 (Blank sample for use in assessment of effects due to sample shipment. Previously numbered as BHV-7) See Attachment A to Section 1.1 of this Environmental Protection Manual for the locations of these monitoring stations. Samples are collected on a quarterly basis using Radtrak® (Trac-Etch) Outdoor Air Radon Detector, (Landauer Part Number DRNM) or equivalent. One or more than one Radtrak® (Trac-Etch) Outdoor Air Radon Detector will be placed at each of the locations noted above (except BHV-70). The number of detectors to be placed at each location shall be as determined by the Radiation Safety Officer ("RSO"). If multiple Radtrak® detectors are placed at one location, the numeric average of the results for that location will be calculated and reported as the radon value for the quarter. Radtrak® (Trac-Etch) detector results will be reported in the Semi-Annual Effluent Report. 1.2 Quality Assurance Quality assurance of the samples is met by collecting samples in accordance with the conditions and guidelines set forth in Section 2 of this procedure. In addition, the following steps will be followed: a) One duplicate sample or set of duplicate samples will be collected each quarter by placing samples at the same location as the routine sample(s), at the same height as the routine sample(s), and as close to the routine sample(s) as reasonably achievable; White Mesa Mill - Standard Operating Procedures Book #11, Environmental Protection Manual, Section 1.2 Date: 11/14 Revision: EFR-3 Page 2 of 3 b) A field blank sample will be collected each quarter to assess any concentrations resulting from shipment of the detectors; c) Detector locations will be monitored periodically to ensure the detectors have not been lost; d) Detector shipments will be inspected to ensure that all detectors are present when receiving or shipping detectors; and e) Monitoring data will be reviewed for consistency and data transportation issues/detections. 1.3 Analytical Requirements Each quarterly sample will be analyzed for Radon-222. Results will be expressed in Samples will be collected using the Radtrak® (Trac-Etch) Outdoor Air Radon Detector (Landauer Part Number DRNM) or equivalent. The detectors will be returned to the supplier/manufacturer for processing and analysis. Detectors are analyzed using the "high sensitivity" methodology, which provides a lower limit of detection of 6.0 pCi/L- days. 2.2 Monitoring Methodology The following monitoring procedures will be followed: a) Remove detector from package - The Radtrak® radon detectors are supplied in aluminum bags which prevent radon exposure. Open the aluminum bag and remove the clear plastic cup which has a Radtrak® detector fastened to the bottom. Detectors, before, during or after exposure should not be in locations which exceed a temperature of 160°F (70°C). There is no low temperature. b) Fill in the enclosed Detector Log Sheet with the serial number on the detector label. Also fill in the date installed and the location information in the location/comments area. c) Attach a field canister to a post or other location using the metal bracket with the open mouth of the canister facing down. The canister may be placed at any desired height (typically 3-6 feet) and preferably in a location minimizing animal damage or tampering. Remove the clear acrylic retaining ring from the canister by removing the wing nuts. Install the assembled cup inside the canister and replace the retaining ring and wing nuts in order to hold the cup in place. pCi/L. 2.

White Mesa Mill - Standard Operating Procedures Book #11: Environmental Protection Manual, Section 1.4 Date: 1 l/14Revision: EFR-4 Page 1 of 6 STACK EMISSION MONITORING PROCEDURES WHITE MESA GAS STACK EMISSIONS 1.0 INTRODUCTION White Mesa, or it's contracted service providers, uses scientifically approved reference methods to determine gas stack emissions release concentration for radionuclide particulates. These methods conform to principles that apply to obtaining valid samples of airborne radioactive materials, using prescribed acceptable methods and materials for gas and particulate sampling. See American Standard Guide to Sampling Airborne Radioactive Materials in Nuclear Facilities ANSI N13.1-1969. These sampling methods are also consistent with guidance contained in the U.S. Nuclear Regulatory Commission's Regulatory Guide 4.14, "Radiological Effluent and Environmental Monitoring at Uranium Mills." 2.0 SAMPLING METHODOLOGIES The sampling methods for airborne radionuclide particulates, from the yellowcake dryer and other mill effluent control stacks, are identical to methods published in the EPA's manual, Gas Stream Sampling Reference Methods for New Source Performance Standards; they are found in the EPA Manual in Appendix No. 5, "Determination of Particulate Emissions from Stationary Sources" ("EPA Method #5") and Appendix No. 17, "Determination of Particulate Emissions from Stationary Sources (In-Stack Filtration Method)" ("EPA Method #17). Copies of EPA Method #5 and #17 are attached to this SOP. Sampling is performed as per the methods, to ensure that the sampling and results are: (1) isokinetic; (2) representative; and (3) adequate for determination of the release rates and concentrations of U-Nat, Th-230, Ra-226 and Pb-210. 2.1 Sampling Equipment Sampling equipment used to collect airborne radionuclide particulates from point source emission stacks at the Mill consists of equipment manufactured by Research Appliance Company (RAC), (or other equivalent apparatuses), as follows: 1. RAC Model 201009 Model 2414 stack sampler. 2. Two each, RAC Model 201044 modular sample cases. One heater box and one glassware box. 3. One each, RAC Model 201019 umbilical cord.

Three each, RAC Model 201013 - 100mm diameter filter holders. 5. One each, RAC Model 201005 standard pilot tube, three feet length, stainless steel/S-type probe. 6. Barometer. 7. Psychrometer. 8. Satorius Model 2432 balance or equivalent. 9. Triple beam balance. Equipment instruction and operating manual(s) provided by the manufacturer(s) are retained at the Mill and used for specific guidance and reference. 2.2 Sample Collection Gas stack samples are collected from emission control systems used in Recovery Operations at the Mill. These samples are collected from process stacks when the emission control systems are operating. They are sampled for radionuclide particulate concentrations at a frequency in accordance with Table 5-1. Sample collection methods are described in detail in EPA Method #5 and EPA Method #17, Determination of Particulate Matter Emissions From Stationary Sources. It is necessary to read and understand all procedures described in the methods and in the equipment manual. The operation of the equipment requires "hands-on" instruction from the Environment Departmental Staff from individuals who are experienced in using sample collection equipment and applying sample collection methods. The following steps are described for stack sample collection. 1. Check equipment listed in Section 2.1 of this SOP. Consult the manufacturers equipment operations manual for details. 2. Assemble equipment as described in the operations manual for sample collection EPA Method #17. 3. Follow the calibration procedure listed in the manual. If the calibration measurements are not obtained, consult the trouble shooting section of the manual for corrective instruction. Once the collection apparatus is calibrated, proceed to the next step. 4. Weigh a new glass fiber filter, record the weight, and place in the filter holder assembly. 5. Check the sample collection system for leaks. 6. Cap ends of sample probes to prevent contamination and transport sample unit to the sample location. 7. Uncap sample end and insert 3/8-diameter sample probe into the stack in the midsection of the exhaust stream. 8. Turn sample apparatus on and observe unit operation to insure a sample is being collected and the apparatus is functioning properly. 9. Collect the stack sample for at least one hour during periods of routine process operation. Note the collection time. N:\WMM\SOPs and ProceduresVEPM - November 2014 Revision\Section 1.4 Stack MonitoringVAppendix E-Section 1.4 Stack Emission 4 - Nov 2014 - clean.doc White Mesa Mill - Standard Operating Procedures Book #11: Environmental Protection Manual, Section 1.4 Date: 1 l/14Revision: EFR-4 Page 3 of 6 10. Record the information described in the manufacture's operations manual. This information is also described in the EPA Methods #5 and #17 for point source particulate emissions. 11. After sample collection is complete, turn off unit. Obtain sample filter from filter housing and place in a new plastic petri dish. Send to outside laboratory for radionuclide analysis in accordance with Table 5-1. 2.3 Sample Handling and Shipping 1. During preparation and assembly on the sampling train, keep all openings where contamination can occur covered until just prior to assembly or until sampling is about to begin. 2. Using a tweezer or clean disposable surgical gloves, place a labeled (identified) and weighed filter in the filter holder. Be sure that the filter is properly centered and the gasket properly placed so as to prevent the sample gas stream from circumventing the filter. Check the filter for tears after assembly is completed. 3. Before moving the sampling train to the cleanup site, remove the probe from the sample train, wipe off the silicone grease, and cap the open outlet of the probe. Be careful not to lose any condensate that might be present. Wipe off the silicone grease from the filter inlet where the probe was fastened, and cap it. Remove the umbilical cord from the last impinger, and cap the impinger. If a flexible line is used between the first impinger or condenser and the filter holder, disconnect the line at the filter holder, and let any condensed water or liquid drain into the impingers or condenser. After wiping off the silicone grease, cap off the filter holder outlet and impinger inlet. Either ground-glass stoppers, plastic caps, or serum caps may be used to close these openings. 4. Transfer the probe and filter-impinger assembly to the cleanup area. This area should be clean and protected from the wind so that the chances of contaminating or losing the sample will be minimized. 5. Save a portion of the acetone used for cleanup as a blank. Take 200 ml of this acetone directly from the wash bottle being used, and place it in a glass sample container labeled "acetone blank." 6. Carefully remove the filter from the filter holder, and place it in its identified petri dish container. Use a pair of tweezers and/or clean disposable surgical gloves to handle the filter. If it is necessary to fold the filter, do so such that the PM cake is inside the fold. Using a dry Nylon bristle brush and/or a sharp-edged blade, carefully transfer to the petri dish and PM and/or filter fibers that adhere to the filter holder gasket. Seal the container. 7. Send to the laboratory for radionuclide analysis.

Calibration of equipment is checked on a periodic basis. Probe tips are protected by a protective cap while not in use to protect accuracy determinations. During transport of equipment, all openings are sealed to prevent contamination. Calculations utilized during runs to maintain isokinetic conditions are reviewed and dry run tested prior to the actual run. All containers and probes are washed prior to each usage.

A field logbook shall be maintained listing data generated, determinations of volumes measured, and net gain weights of filters to provide a back up to summary data records. Filters are transmitted within plastic enclosed petri dishes. Handling of filters is only done using tweezers. 6.4 Calculations All calculations will be retained at the Mill in both a hard copy and computer files. The gas stack effluent concentrations (C) are calculated as follows: Lab Result uCi (A) / Volume Sampled (V) = Effluent Concentration (C) where Volume Sampled (V) = Flow rate (Q) * Time of sample collection in minutes (t) and Lab Result uCi (A) = Radioisotopic activity, in pCi on air filter N:\WMM\SOPs and ProceduresVEPM - November 2014 RevisionVSection 1.4 Stack MonitoringVAppendix E-Section 1.4 Stack Emission 4 - Nov 2014 - clean.doc White Mesa Mill - Standard Operating Procedures Book#l 1, Environmental Protection Manual, Section 4.1 SURFACE SOIL MONITORING PART I SOIL MONITORING PLAN 1.0 SOIL MONITORING Surface soils are sampled at the eight air monitoring sites and at spaced intervals around the perimeter boundary of the Mill property. The sampling locations are shown in Figure 1. Soil samples from the northern Mill boundary and the north half of the eastern boundary (adjacent to Sections 22,27 and 34) are collected approximately every 1000 feet. The remainder of the perimeter boundary soil samples are collected every 2500 feet. Soil samples are taken once per year during August or as soon as possible thereafter, but no later than September 30 of the year. Each soil sampling location will be marked with an aluminum tag with the sample location identification etched or painted on the tag. The tags will be attached to a metal stake driven approximately 18 inches into the ground. The sampling locations will be placed on the inside of the Mill's perimeter fence to prevent tampering and vandalism. The locations will be sited approximately one foot from the inside of the perimeter fence to prevent inadvertent disturbance by truck or vehicle traffic. The location markers will be designed and installed with as low a profile as possible, while still maintaining visibility for ease of location during the annual sampling program. In addition, a soil sample could be taken from Westwater Creek, in the place of a water sample. However, a sediment (soil) sample would only be taken at Westwater Creek if water was not available. In the event that a soil sample is collected in place of a water sample for Westwater Creek, the sample should be analyzed for the same parameters as those called for in this SOP (Radium-226 and U-nat). Refer to SOP No. PBL-EP-3 for details regarding collection of a water sample from Westwater Creek. 2.0 SAMPLING AND ANALYTICAL QUALITY ASSURANCE The sample bags are marked for location identification and are submitted to the analytical laboratory accompanied by Chain-of-Custody forms. (Attachment A) Analytical quality assurance for soil monitoring is based on the contract laboratory's quality controls such as blanks, duplicates, and standard percentage recovery. The laboratory is committed to meet the LLD values for radionuclides contained in U.S. NRC Regulatory Guides 4.14 and 4.15 and will perform re-runs on all samples not meeting these limits. Appropriate laboratory control and quality assurance data will be provided by the contract laboratory, or equivalent, including LLD information. 3.0 ANALYTICAL REQUIREMENTS All soil samples will be analyzed, on a dry basis for the following radionuclides: Ra-226 Th- 232, Pb-210, and U-Nat. Analytical results will be reported in appropriate radiological units such as pico curies per gram or micro curies per kilogram.

Tape measure or measuring stick calibrated to 1 foot and to one centimeter. 2. Clean trowel or shovel. 3. Clean sample containers. 1.2 Soil Sampling Procedure Soil samples are collected using a clean trowel or shovel to excavate a soil sample evenly across a one square foot area at a depth of one centimeter. The one centimeter excavation depth is maintained by using the tape measure or other suitable calibrated measuring stick. As the soil is being collected, it is placed directly into the sample container. The sample container is then identified with a label (see Section 2.1 below). 2.0 SAMPLING QUALITY ASSURANCE 2.1 Sample Duplicates Soil sample duplicates will be collected at a frequency of 1 duplicate per 20 samples. The duplicates will be submitted blind to the laboratory and will be named as follows: N1D where: N = Northern boundary 1 = Sequential number of the northern boundary sample D = Duplicate of sample N1 Duplicate precision will be discussed in the Semi-Annual Effluent Report. Duplicate precision will be assessed as follows: a) Relative Percent Difference. RPDs will be calculated in comparisons of duplicate and original field sample results. Section 3.3 will apply when the RPD >_35%, unless the measured concentrations are less than 5 times the required detection limit (Standard Methods, 1998) (EPA Contract Laboratory Program National Functional Guidelines for Inorganic Data Review, February 1994, 9240.1-05-01, p. 25).

Record the initial meter reading (V,) in column 1 of Figure 4. 9.2.11 Maintain this constant flow rate until at least 3 m3 of air have passed through the standard volume meter. Record the standard volume meter inlet pressure ma- nometer reading as AP (column 5 in Figure 4), and the orifice manometer reading as AH (column 7 in Figure 4). Be sure to indicate the correct units of measurement. 9.2.12 After at least 3 m3 of air have passed through the system, observe the standard volume meter reading while simultaneously stopping the stopwatch. Record the final meter reading (Vf) in column 2 and the elapsed time (t) in column 3 of Figure 4. 9.2.13 Calculate the volume measured by the standard volume meter at meter condi- tions of temperature and pressures as Vm=Vf-Vi. Record in column 4 of Figure 4. 9.2.14 Correct this volume to standard vol- ume (std m3) as follows: V . =V std m P, - AP T sid P T std M where: v«d = standard volume, std m3; Vm - actual volume measured by the stand- ard volume meter; Pj = barometric pressure during calibration, mm Hg or kPa; AP = differential pressure at inlet to volume meter, mm Hg or kPa; P.ui = 760 mm Hg or 101 kPa; TIld = 298 K; Ti = ambient temperature during calibra- tion, K. Calculate the standard flow rate (std m3/min) as follows: Qstd = _Vs.d t where: QUui = standard volumetric flow rate, std m3/ min t = elapsed time, minutes. Record Qstd to the nearest 0.01 std m3/min in column 6 of Figure 4. 9.2.15 Repeat steps 9.2.9 through 9.2.14 for at least four additional constant flow rates, evenly spaced over the approximate range of 1.0 to 1.8 std m-Vmin (35-64 ft3/min). 9.2.16 For each flow, compute •AAH (Pi/P8td)(298/T1) (column 7a of Figure 4) and plot these value against Q.W as shown in Figure 3a. Be sure to use consistent units (mm Hg or kPa) for bar- ometric pressure. Draw the orifice transfer standard certification curve or calculate the linear least squares slope (m) and intercept (b) of the certification curve: •AAH (P1/P8td)(298/T1) =mQ«d+b.

NOTE: For samplers equipped with a flow controlling device, the flow controller must be disabled to allow flow changes during calibration of the sampler's flow indicator, or the alternate calibration of the flow con- troller given in 9.4 may be used. For sam- plers using an orifice-type flow indicator downstream of the motor, do not vary the flow rate by adjusting the voltage or power supplied to the sampler. 9.3.1 A form similar to the one illustrated in Figure 5 should be used to record the cali- bration data. 9.3.2 Connect the transfer standard to the inlet of the sampler. Connect the orifice ma- nometer to the orifice pressure tap, as illus- trated in Figure 3b. Make sure there are no leaks between the orifice unit and the sam- pler. 9.3.3 Operate the sampler for at. least 5 minutes to establish thermal equilibrium prior to the calibration. 9.3.4 Measure and record the ambient tem- perature, T2. and the barometric pressure, P2. during calibration. 9.3.5 Adjust the variable resistance or, if applicable, insert the appropriate resistance plate (or no plate) to achieve the desired flow rate. 9.3.6 Let the sampler run for. at least 2 min to re-establish the run-temperature condi- tions. Read and record the pressure drop across the orifice (AH) and the sampler flow rate indication (I) in the appropriate col- umns of Figure 5. 9.3.7 Calculate •AAH(P2rJ?«d)(298/T2) and de- termine the flow rate at standard conditions (Q»td) either graphically from the certifi- cation curve or by calculating Q»t<i from the least square slope and intercept of the trans- fer standard's transposed certification curve: Q8td=l/m •AH(P3/PBtd)(298/T2)-b.
