O. Box 669 Blanding, Utah 84511 1.0 INTRODUCTION During September 1990, ARIX Corporation provided support to UMetco Minerals Corporation (Umetco) regarding their required National Emission Standards for Hazardous Air Pollutants (NESHAPs) Radon Flux Measurement effort on Tailings Cells 2 and 3 at the White Mesa Mill in Blanding, Utah uranium processing facility. These measurements are required of Umetco to show compliance with 40 Code of Federal Regulations, Part 61, Subpart W, National Emission Standards for Radon Emissions from Operating Mi11 Tailings. At present, there are no Subpart T uranium mill tailings at this site. According to the regulations, the NESHAP for existing mill tailings piles is a flux standard that limits the emission of radon from piles. The Standard limits the amount of radon that can be emitted per unit area (m2) per unit of time (s). This standard is not an average per facility, but is an average per radon source. According to subsection 61.252 Standard, (a) radon-222 emissions to ambient air from an existing uranium mill tailings pile shall not exceed 20 pCi/m2-s of radon-222. Subsection 61.253 Determining Compliance. states that: "Compliance with the emission standard in this Subpart shall be determined annually through the use of Method. 115 of Appendix B." ARIX Corporation (Grand Junction) was contracted to provide radon collectors, field placement/retrieval of said collectors, and lab analysis for calendar year 1990. This report addresses the procedures employed by ARIX to obtain the results presented in Section 6.0 of this report. 1 DEQ_NRC000520 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 7 of 156 2.0 SITE DESCRIPTION The White Mesa Mill is located south of Blanding, Utah on Highway 191. The mill began operations in 1980 for the purpose of extracting uranium and vanadium from feed stocks. Processing effluents from the operation are deposited in four "lined" cells. which vary in depth (reference Figure 6-1). Cells 1-I and 4A are used solely for "liquor" storage, and Cells 2 and.3 are used for sand tailings/liquor deposition. Cell 2 has a total area of 66.2 acres. This cell was comprised of three source regions that required NESHAPs radon monitoring: approximately 20.9 acres of the cell had a soil cover of varying thickness; exposed dry tailings "beaches" over approximately 18.1 acres; approximately 25.8 acres were considered to be wet tailings "beaches." The remaining 1.4 acres were covered by standing liquid in "low" elevation areas. At the time of the monitoring effort, Cell 2 was not actively receiving tailings deposition. Cell 3 has a total area of 68.9 acres. This cell was comprised of two source regions that required NESHAPs monitoring: approximately 6.9 acres had exposed dry tailings "beaches" and approximately 24.4 acres were considered to be wet tailings "beaches." The remaining 37.6 acres of the cell had free-standing liquids and required no radon monitoring. Cell 3 was actively receiving tailings/liquor effluents during the radon measurement period and in some areas was very dynamic. Due to worker health and personnel safety concerns expressed by both Umetco site and ARIX .monitoring staff, large areas of the wet beaches of Cell 3 were not investigated due to the extreme instability of the recently placed wet tailings beaches. 2 DEQ_NRC000521 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 8 of 156 3.0 SAMPLER DESCRIPTION ARIX fabricated Large Area Activated Charcoal Canisters (LAACC) for use by ARIX personnel to perform the required radon measurements. The LAACC were fabricated in conformance with "Radon Flux Measurements on Gardinier and Royster Phosphogypsum Piles near Tampa and Mulberry, Florida" (NTIS Document #PB86-161874) as referenced in 40 CFR, Part 61, Method 115, Appendix B. This method of performing radon flux measurements involves the absorption of radon on activated charcoal in a large-area collector. The charged collector is placed directly on the material surface to be measured and is allowed to collect radon for a given time period (24 hours). The radon collected on the activated charcoal is then measured by means of gamma spectroscopy. Each LAACC was constructed using a 10-inch diameter PVC end cap, spacer pads, charcoal distribution grid, retainer screens, pads, and a steel retainer ring (see Figure 1). Prior to deployment, each collector was charged with 180 grams of baked charcoal from sealed individual sample containers (reference Section 5.0 below for laboratory procedures). After the 24 hour measurement period, the exposed charcoal was transferred to the plastic sample containers, sealed air-tight (with tape), labeled as. to sample identification along with exposure times/dates, and transferred to the ARIX laboratory (Grand Junction, Colorado) facility for analysis. 3 DEQ_NRC000522 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 9 of 156 Figure 1 Large Area Radon Collector (LAACC) Handle 1 /4.in.

DEQ_NRC000523 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 10 of 156 4.0 FIELD OPERATIONS 4.1 General Site Specific Information Prior to commencement of field work operations, the Client provided ARIX with base maps detailing Cells 2 and 3., A grid coordinate location system was developed for each cell to accommodate locating the samplers in the field. East/west and north/south (0 lines) were established for each cell and then a 100-foot traverse grid was developed off of each baseline. In order to perform the required 500 NESHAPS radon measurements, two field trips were scheduled to obtain the measurements. The first sampling effort (September 5 through September 11) dealt with the three source regions on Cell 2 (wet and dry beaches and the cover area). The second sampling effort (September 24 through September 27) dealt with the two source regions on Cell 3 (wet and dry beaches). The first sampling effort commenced on September 5, 1990. After site specific health and safety training provided by Umetco Health and Safety personnel, ARIX field technicians laid out the baselines and traverse grid system on Cell 2 utilizing measuring tape, transit and line-of-sight. The grid coordinates were identified both on the field maps and grid lath stakes in the field. Boundary distinctions between the three source regions were established .by visual inspection and so noted on the field maps. ARIX personnel also activated a weather station, located along the north edge of Cell 2 (grid coordinates W 2200, 0 S), to provide a continual record of ambient air temperatures to assure compliance with the 35*F measurement criterion. (See Section 4.5 for site atmospheric conditions and Appendix A for complete temperature support data.) The second sampling effort was originally scheduled to commence on September 17, 1990. After arrival at the site, excessive measurable rainfall (greater than 0.01") required a re-schedule as measurement rainfall sampling criterion was exceeded. This effort was re-scheduled and commenced on September 24, 5 DEQ_NRC000524 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 11 of 156 1990. This effort was concentrated on the two source regions of Cell 3. Prior to placement of samplers on Cell 3, the wet beach region, precipitation was 0.01" within the preceding 24-hour period. Since projected weather conditions called for clearing weather and the sample area was to be wet beaches, it was agreed by the Client Representative and ARIX Field Supervisor to commence sampling efforts. 4.2 Sampler Placement Radon measurements were made in conformance with methods described in NTIS Document OPB86-161874 for each 100 sample measurement set for each source region. In addition to the 100 samples, each sample set consisted of 5% field blanks. The spacing distribution for each set of 100 measurements was determined by visual means and a "best fit" distribution pattern for each source region. Field personnel safety was paramount in the distribution of samplers over "wet beach" regions due to the loose, unconsolidated condition of the saturated tailings, which are similar in consistency to "quicksand." Placement of collectors was accomplished from a vehicle where possible and by foot travel where required, due to access. A collector was chosen and the retaining ring, screen and foam pad removed to expose the charcoal support grid. A pre-measured charcoal charge was selected from a batch, opened and distributed evenly across the area of the support grid. The collector was then re-assembled and gently placed face down on the surface to be measured. Care was exercised not to "push" the device into the soil surface. collector rim was "sealed" to the surface using ,a berm 'of local The borrow material (either tailings or soil) to reduce dilution due to air or wind currents within the collector. A sample identification number was then assigned to the collector. Sample numbers utilized an alpha-numeric system composed of the charcoal batch letter (i.e., A, B, C . . .) followed by a sequential number indicating the placement (i.e., 001, 002, . . .). This sample identification number was recorded on an adhesive label and placed on the top of the collector. The grid location, 6 DEQ_NRC000525 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 12 of 156 sample ID, date and time of placement were recorded on a master data sheet for each set of measurements. The charge container was retained for sample retrieval upon completion of the measurement time period (24 hours). During placement of charcoal collected. flux collectors, five field blanks were The procedure for field blanks was to charge a collector with charcoal, and place it inside an air-tight container. The blank remained in the sealed collector for the 24-hour sample time period. Upon retrieval of the collectors, the field blanks were retrieved and the charcoal charge returned to a container, sealed, and labeled as such, and returned for analysis along with the measurement set. 4.3 Sampler Retrieval Retrieval of the collectors followed the same pattern as placement. The collectors were disassembled and the charcoal charges remove by pouring from the collector into a large funnel suspended above a sample charge container. The sample ID number was transferred to the charge container which was sealed and placed in a box for transport. The date and time of, retrieval were recorded on the same data sheet as the sample placement information. Sample data sheets accompanied the shipment to the laboratory. ARIX personnel assured timely delivery of the samples to the ARIX Grand Junction laboratory for prompt analysis of the charcoal samples. Collectors were periodically scanned with a GM-tube for alpha/beta radiation to prevent measurement bias due to equipment contamination. Replacement of contaminated components (e.g., screens, foam spacers) was performed as needed to prevent such bias. 4.4 Site Exit ARIX field personnel and equipment were alpha scanned for possible contamination resulting from field work activities. All equipment was surveyed and 7 DEQ_NRC000526 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 13 of 156 released for unrestricted use by Umetco Health and Safety Personnel. field personnel surveyed were found to A11 have no detectable radioactive contamination and were released from the site. 4.5 Environmental Conditions during Measurement Periods Referencing 40 CFR, Part 61, Subpart W, Appendix B, Method 115 - Monitoring for Radon-222 Emissions, Subsection 2.1.4 - Restrictions to Radon Flux Measurements, "the following restrictions are placed on making radon flux measurements: (a) Measurements shall not be initiated within 24 hours of a rainfall. (b) If a rainfall occurs during the 24 hours measurement period, the measurement is invalid if the seal around the lip of the collector has washed away or if the collector is surrounded by water. (c) Measurements shall not be performed if the ambient temperature is below 35°F or if the ground is frozen." Site Specific Discussion (a) For this measurement sampling program, rainfall did not affect measurement initiation except on September 17 which required a site rescheduling. Prior to commencement of any sampler placement, rainfall amounts (if any) were confirmed at the Umetco weather station rain gauge. (b) Rainfall did occur during placement of samplers on September 6, 1990 (dry beach region, Cell 2). Sampler placement was terminated as rainfall increased. Total number of samplers placed was 94 of the 100 measurement sample set. Recovery was 100% of the placed detectors; no wash of seals was noted. (c) During all 24-hour sample set placements, the minimum ambient air temperature recorded was 51°F. In addition to continuous ambient air temperature monitoring, ARIX field personnel performed high/low soil surface temperature measurements for each 24-hour sampling period at selected sample locations. Of all sample periods the maximum soil temperature observed was 124°F, while the observed minimum was 39°F. (Environmental conditions are presented on Table 1 and complete copies of weather station data are presented in Appendix A - Support Documents.) 8 DEQ_NRC000527 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 14 of 156 Table I NESHAPS Radon Monitoring Environmental Conditions at White Mesa Mill, Utah September 1990 Date Sample Subject Ambient Temperature ('F) minimum/maximum 9/6 - 9/7 Cell 2 - Dry Tailings 60/83 S0150 S0200 S0200 S0400 S0450 W1250 W2800 W3200 W0800 W1850 50/115 61/ 97 59/ 95 46/109 55/113 9/8 - 9/9 Cell 2 - Cover 61/94 S0010 S0300 S0700 S0900 W0010 W0300 W0700 W0300 55/124 57/115 59/111 61/117 9/10 - 9/11 Cell 2 - Wet Tailings 63/91 S0125 S0200 S0300 S0830 W1100 W3250 W2400 W1570 73/ 73 64/102 64/100 63/ 90 9/24 - 9/25 Cell 3 - Wet Tailings 51/80 S0100 W2250 S0450 .

Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 15 of 156 5.0 LABORATORY OPERATIONS 5.i Introduction Activated charcoal gas absorption collectors are passive sampling devices used to determine the flux rate of radon-222 gas from a surface area. The charcoal canister used consists of a 10-inch PVC cap containing a bed of 180 grams of activated, granular charcoal placed in a distribution grid on top of a 1i inch thick layer of foam and secured under a inch foam layer and a galvanized steel screen by a retaining ring. Sample collection is initiated by placing 180 grams of unexposed charcoal from a sealed container into the above described canister and, after securing the retaining ring, placing the canister (open face down) onto the surface to be tested. Radon gas is adsorbed on the contained charcoal and subsequent radioactive decay of the entrained radon results in the occurrence of radioactive lead-214 and bismuth-214 in the canister. These radon progeny isotopes emit characteristic gamma photons which can be detected. The original total activity of the adsorbed radon can be calculated from these gamma ray measurements using empirical calibration factors derived from crosscalibration of source standards containing a known total activity of radium226 in a geometry identical to the samples to be counted. 5.2 Apparatus Single- or multi-channel pulse height analysis system, Ludlum Model .2200 with a Teledyne 3" x 3" NaI(T1) detector. Lead shielded counting well approximately 40 cm deep with 5 cm thick lead walls and a 7 cm thick base and 5 cm thick top. NBS traceable aqueous solution radium-226 absorbed onto 180 grams of activated charcoal check source and Eberline Model CS-7A cesium-137 check source. Ohaus Model C501 balance with 0.1 gram sensitivity. 10 DEQ_NRC000529 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 16 of 156 5.3 Analysis Procedure Inspection of the Charcoal Container Charcoal was received at the analytical containers. laboratory in the sealed sample Upon receipt, the integrity of the container was verified by inspection of the plastic container per se, as well as the sealing tape. Sample Identification Numbers Each sample container had a unique sample identification number which was determined in the field, and written onto a label attached to the sample container. Drying and Recycling A11 charcoal was dried before use in the field for radon flux measurements. Procedures were the same for newly prepared charcoal and for charcoal recycled after field use. Charcoal was dried at 110*C. Drying procedures were as follows: • Oven temperature set to 110*C. Charcoal placed in the oven in a metal baking tray. Dried for 24 hours. • Immediately after the tray was removed, exactly 180 grams of charcoal were transferred into clean sample containers and sealed with plastic tape. 5.4 Weighing and Background Counting Proper balance operation was verified daily by checking with a standard weight. The balance readout should agree with the known standard weight to within ± 0.1%. If a discrepant readout was obtained, the balance was re- zeroed, the check weight wiped with a soft, lint-free cloth, and re-weighed. If the discrepancy persisted, the balance would have been removed from service and tagged "Out of Service." (For this project, the scale conformed for each day of use.) 11 DEQ_NRC000530 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 17 of 156 After acceptable balance checkout, each empty container was individually placed on the balance and the tare weight of the container was documented to the nearest 0.1 grams on the label. The scale was re-zeroed with the container on the balance. Charcoal was carefully added to the container until the readout registered exactly 180 grams. The lid was immediately placed on the container and sealed with plastic tape. The tape was stretched slightly The end of the tape was folded to form while wrapping around the container. a tab for easy tape removal. The balance was checked for readout drift between each container weighing step. Gamma ray counting system checkout was performed as described in Section 5.6. A five-minute background count was acquired for five containers selected at random to represent the "batch." Each sealed container was placed indi- vidually in the shielded counting well, with the bottom of the container centered on the detector. Observed container background counts must fall within the range of 190 ± 30 corn using the existing Ludlum/Teledyne counting system, shielded well, and 4-inch high by 3-inch diameter containers. The background count rate was documented for the five containers on the respective "Radon Flux Field Data Sheet" for that batch. If the background counts were higher than the count range above, the entire batch was labeled non-conforming and recycled through the drying process. 5.5 Receipt and Weighing of Exposed Charcoal Containers of exposed charcoal were delivered to the laboratory for analysis by common carrier. The laboratory staff was responsible for receipt, log-in, weighing and inspection of the exposed canisters; inspection of the documentation forms; and entry of the required documentation to data base spreadsheets. When the containers were received, the following items were inspected: Container was closed and sealed with tape. Container was not damaged. Data sheet was complete. • Discrepancies found during the receipt inspection were documented on the data sheet. 12 DEQ_NRC000531 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 18 of 156 Containers received open or damaged resulting in seal failure were considered void and were not analyzed. (A11 containers received during this analysis effort were of sound integrity.) After receipt inspections, sealing tape was removed from conforming containers and were then weighed on a balance to the nearest 0.1 gram and the gross weight was logged on the "Radon Flux Field Data Sheet" under the appropriate column. 5.6 Gamma Ray Counting Source/Background Checks The charcoal gamma ray counting system was subjected to performance checks daily when used. These checks included background cesium-137 and radium-226 check source measurements. (Appendix A contains daily counting system performance check records.) Sample Analysis • The length of count time was determined by the activity of the sample being analyzed. A minimum of 1000 counts above background had to be accrued for any given sample. The sample container was placed in the counting well with the lid side up and the center on the NaI detector and the shielded well door was moved into place. • One sample count was accrued and the mid-sample count time and date was documented on the field data sheet. The sample counts were documented on the field data sheet filed for data reduction. • The above steps were repeated for each exposed sample collector. 10% of the containers counted on a given date were selected for recounting. These containers were recounted no sooner than 1 day and no longer than 10 days following the original count. 13 DEQ_NRC000532 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 19 of 156 5.7 Quality Control Samples Charcoal flux measurement QC samples included the following intra-laboratory analytical objectives as required in 40 CFR, Part 61, Subpart W, Appendix B, Method 115, 4.0 - Quality Assurance Procedures for Measuring Ra-222 Flux, D.: • recounts, 10%, and • equipment blanks, 5%. In addition to the above described required quality control samples, ARIX performed side-by-side measurements at 10% of the locations measured within each region for comparative analysis. These samples were statistically evaluated for completeness, precision and accuracy. (Note: Reference Appendix B for entire summary analysis of recount, equipment blank, and siceby-side measurement results.) 5.8 Data Validation - Recounts/Blanks All sample canister data were subjected to validation protocols. The following presents data validation results by specific source regions by cell: Cell 2 - Dry Beaches Twelve recount measurements were performed by conducting replicate analyses of individual field samples. These recount measurements comprised 13% of the field measurements. The precision of the recount measurements ranged from less than 1% to 5% with a mean precision of 2%. This recount precision is well within the expected variability of the analytical method. Five equipment blanks were analyzed by measuring the radon progeny activity in samples subjected to all aspects of the measurement process, excepting exposure to the source region. These blank sample measurements comprised 5% of the field measurements. The results of the blank sample analyses ranged from less than 0.1 to 0.3 pCi/m2-s. This mean blank value corresponds to 1% of the regulatory limit of 20 pCi/m2-s. 14 DEQ_NRC000533 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 20 of 156 Cell 2 - Wet Beaches Ten recount measurements were performed by conducting replicate analyses of individual field samples.

These blank sample measurements comprised 5% of the field measurements. The results of the blank sample analyses This mean blank value ranged from less than 0.1 to 0.2 pCi/m2-s. corresponds to 1% of the regulatory limit of 20 pCi/m2-s. Cell 3 - Dry Beaches Fourteen recount measurements were performed by conducting replicate analyses of individual field samples. These recount measurements comprised 14% of the field measurements. The precision of the recount measurements ranged from 1% to 7% with a mean precision of 3%. This recount precision is well within the expected variability of the analytical method. Seven equipment blanks were analyzed by measuring the radon progeny activity in samples subjected to all aspects of the measurement process, excepting exposure to the source region. These blank sample measurements comprised 7% of the field measurements. The results of the blank sample analyses ranged from less than 0.1 to 0.6 pCi/m2-s. This mean blank value corresponds to 3% of the regulatory limit of 20 pCi/m2-s. 15 DEQ_NRC000534 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 21 of 156 Cell 3 - Wet Beaches Sixteen recount measurements were performed by conducting replicate analyses of individual field samples. These recount measurements comprised 16% of the field measurements. The precision of the recount measurements ranged from less than 1% to 8% with a mean precision of 4%. This recount precision is well within the expected variability of the analytical method. Five equipment blanks were analyzed by measuring the radon progeny activity in samples subjected to all aspects of the measurement process, excepting exposure to the source region. These blank sample measurements comprised 5% of the field measurements. The results of the blank sample analyses ranged from less than 0.1 to 1.1 pCi/m2-s. This mean blank value corresponds to 1% of the regulatory limit of 20 pCi/m2-s. As presented above,. actual QC validation met the objective parameter requirements. 5.9 Data Validation - Side-by-Side Measurements Side-by-side measurements were performed at 10% of all sample measurement locations. These side-by-side measurements were performed within inches of the respective field sample location. As the below data results indicate, an overall average a precision of 43% was observed. While this overall average precision falls outside of a typically accepted objective of 20%, we feel the data are valid. Validation exercises included confirming daily equipment source checks, equipment calibrations, raw data computer entry, and computer data base formula reviews. 5.10 Calculations Radon flux rates were calculated for charcoal collection samples using empirical calibration factors derived from cross-calibration of sources with known total activity with identical geometry as the charcoal containers. A yield efficiency factor was used to calculate the total activity of the sample charcoal containers. In practice, radon flux rates were calculated by a data base computer program. The algorithms utilized by the data base program were as follows: 16 DEQ_NRC000535 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 22 of 156 Equation 5.1: N Uncorrected pCi Rn-222/m2sec - [Ts*A*b*o.5(d/91.75) where: N = net sample count rate, cpm under 220-662 keV peak Ts = sample duration, seconds b = instrument calibration factor, cpm per pCi; current value: 0.1827 d = decay time, elapsed hours between sample mid-time and count mid-time A = area of the collector, m2 Equation 5.2: Wf = (Cg where: Ct)*x Wf Cg Ct x = = = = empirical water vapor adsorption correction factor canister gross weight, g canister tare weight, g slope, moisture gain versus radon adsorption interference Equation 5.3: Corrected pCi Rn-222/m2sec =Wf(uncorrected pCi/m2s) + (uncorrected pCi/m2s) where: Wf = water vapor adsorption correction factor from Equation 5.2 Uncorrected pCi/1 = uncorrected radon-222 concentration from Equation 5.1 Equation 5.4: Gross sample, cpm Bkqd, cpm Bkqd count t, min Sample count, t, min Net cpm 2a error = 2 I (sample concentration) Equation 5.5: (CF)(s LLD - [Ts*A*b*0.547P7M] where: confidence factor of the background standard deviation standard deviation of the background count rate sample duration, seconds instrument calibration factor, cpm per pCi; current value: 0.1827 d = decay time, elapsed hours between sample mid-time and count mid-time A = area of the collector, m2 CF Sb Ts b = = = = 17 DEQ_NRC000536 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 23 of 156 6.0 SAMPLE RESULTS/CALCULATIONS Referencing 40 CFR, Part 61, Subpart W, Appendix B, Method 115 - Monitoring for Radon-222 Emissions, Subsection 2.1.7 - Calculations, "the mean radon flux for each region of the pile and for the total pile shall be calculated and reported as follows: (a) The individual radon flux calculations shall be made as provided in Appendix A EPA 86(1).

The submission of this compliance report is an annual requirement for operating uranium mills undet 40 CFR Part 61, Subpart W, National Emission Standards for Radon Emissions From Operating Mill Tailings. As documented in the compliance report, the operation of the uranium mill tailings impoundments is not in compliance with the radon emissions standard of Section 61.252(a); that is an average radon flux not greater than 20 pCi/m2-s. Cell 3 is shown to be in compliance with a mean radon flux of 15.3 pCi/m2-s. However-, Cell 2 is not in compliance with a mean radOn flux of 49.0 pCi/m2-s. In addition to compliance with the radon emission standard, Section 61.252(c) requires compliance with the groundwater quality protection provisions of 40 CFR 192.32(a). EPA Region VIII is requiring Umetco Minerals Corporation to submit groundwater quality monitoring data demonstrating compliance or certification from the U.S. Nuclear Regulatory Commission (NRC) that compliance with such standard is being achieved under the provisions of the NRC license for the White Mesa Mill. The charcoal canister analysis performance of your contractor, ARIX Corporation of Grand Junction, met the calibration and quality assurance requirements of Method 115 of Appendix B with one exception. Section 4.0 C. of Method 115 requires the preparation of two radium-226 spiked charcoal standards to determine the gamma counting system efficiency. Instead of the required two standards, ARIX used only one such standard. Although this deviation is not Considered 7:b be of the DEQ000061 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 94 of 156 severity to reject, the radon data, EPA is requiring adherence to the use of two radium-spiked charcoal standards for all future measurements. Based on the determination of non-compliance, EPA is requiring Umetco to continue monthly reporting, which includes documentation of the remedial action plan for achieving Cell 2 compliance with the radon-222 emissions standard. Please submit the requested information within fifteen (15) working days of receipt of this letter. If there are any questions concerning this matter, pleats contact Monica Moralet at (303) 294-7613 or Dr. Milton Lammering at (303) 293-1713. Sincerely, Irwin L.

Environmental Protection Agency 401 M South West Washington, D. C.20460 NESHAPs Subpart W Compliance Report Dear Mr. Reilly: This report is in accordance with 40 CFR 61 Subpart W, and is for the White Mesa Mill, located five miles south of Blanding, Utah, on Highway 191. The White Mesa Mill is owned by a partnership of Umetco Minerals Corporation (70%) and Energy Fuels, Limited (30%). Mr. Richard A. Van Horn of Umetco is the person responsible for the operation of the mill. Mr. Van Horn and Mr. John S. Hamrick of Umetco have prepared this report. Figure 1 shows the mill and tailings area. As related in previous reports, Cell 3 is in compliance with the NESHAPs standard, while Cell 2 is not. No further NESHAPs testing has been carried out for compliance purposes. 1991 compliance testing will be carried out this year, as per the regulations, and will be done post-construction. The testing will be conducted in the period of August/September/October. U.S. Nuclear Regulatory Commission mandated dust minimization activities at the mill include spraying large quantities of solutions interior to Cell 3 and Cell 2 from April through September. The solutions are basically sprayed 24 hours per day, except during windy conditions. The intention of the spraying is to wet the areas which may be subject to sand movement (which happen to be the dry, sandy beaches). The impact of the spraying on radon emissions has not been measured. Reductions in emission rates are expected and may be substantial. Approximately 35% of the driest sand surfaces in Cell 2 are now wetted. The results of measurements by ARIX contained in the January 24, 1991 report have been used to determine the following proposed method to bring Cell 3 at the White Mesa Mill into compliance with the NESHAPs standard of 20 pCi/m /sec. As shown by the ARIX report, areas of Cell 2 that have the first layer of final cover (four feet thick) are below the standard except for the northeast corner of the cell, which has probably been contaminated by windblown material. This east end of Cell 2 is shown in Figure 2. Umetco will remove a six inch layer from this corner of OFFICIAL DOCKEr DEQ NRC000604 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 96 of 156 the cell (as shown by the shaded area), and will place one foot of random fill material in this area. Umetco will also place more final cover(random fill four feet thick) on the dry beaches in Cell 2, completely covering the dry beaches and bringing down the overall emission rate below the standard. The basis for this action is as follows. The following statistics from Cell 2 will be used to calculate the compliance emission rate: Location Area, m2 Rate, pCi/m2/sec Wet Beaches 104,359 27.5 Dry Beaches 73,216 117.6 5,678 0.0 Standing Liquids Reclamation Cover 84,602 19.5 (6.9 less the NE corner) (See Table 1 for the data used to calculate rates for Cell 2 cover.) Using the grid supplied by ARIX in their report, the area contained in the coordinates 0 south to 300 south by 0 west to 700 west, and in the area 300 south to 400 south by 0 west to 300 west will be removed to a depth of six inches (shown by the shaded area in Figure 2). One foot of random fill material will be replaced in this aria. This will bring the average emission rate of the cover area to 6.9 pCi/m/sec. Umetco will place a four foot lift of random fill over the dry beaches. The calculated emission rate is then: Cell 2 = 14.8 pCi/m2/sec (27.5)(104,359)+ (6.9)(84,602 + 73,216) + (0)(5,678) 267,854 Umetco has prepared Specifications for the Project and has held a pre-bid meeting on May 23, 1991 at the White Mesa mill with interested contractors. Bids will be received until June 5, 1991, with the final contract awarded on June 18, 1991. Umetco, in accordance with the regulations, will continue to report monthly the progress made in achieving this plan.

Notification of Pending EPA Enforcement Action Against Umetco Minerals Corporation Dear Burnell: Pursuant to the provisions of the Utah/EPA Enforcement Protocol, I am notifying you of pending EPA enforcement action against a Utah source, Umetco Minerals Corporation. Umetco has been found in violation of National Emission Standards for Hazardous Air Pollutants (NESHAP), at 40 CFR Part 61, Subpart W. The nature of the violation is exceedance of the NESHAP emission limit for Radon-222, which is 20 picoCuries per square meter per second (pCi/m2-sec). The Mean measured value at Umetco's White Mesa Mill, in Blanding, Utah, during 1990, was 49 pCi/m2-sec. This is not an overfile action and is not intended to reflect upon the adequacy of the State's enforcement program. The action must be taken by our office, rather than the State, because NESHAP Subpart W has not yet been delegated to the State. We have been advised by Headquarters that the radionuclides NESHAPs cannot be delegated to States via the incorporation-byreference mechanism, which Utah employs. If any State wishes to assume delegation of these particular NESHAPs, a special written request must be submitted to EPA. If you have any questions, please contact the assigned EPA attorney, Terry Lukas, at (303) 294-7195, or our technical staff expert on the radionuclides NESHAPs, Monica Morales, at (303) 294-7613. In accordance with the Enforcement Protocol, a copy of the EPA enforcement action will be sent to you upon issuance.

Section 7413(a)(3), the United States Environmental ProteCtion Agency, Region VIII (EPA), by authority duly delegated to the Director of the Air and Toxics Division, and upon the basis of available information, hereby states the following Findings of Fact, Conclusions of Law, and Order. FINDINGS OF FACT 1. Umetco Minerals Corporation ("the Company") owns and operates a uranium processing facility, the White Mesa Mill, near Blanding, Utah. The facility has two operating mill tailings piles, designated Cell 2 and Cell 3. DEQ000238 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 108 of 156 2. As operating mill tailings piles, Cells 2 and.3 are subject to Title 40 of the Code of Federal Regulations ("CFR"), at 40 CFR Part 61, Subpart W, National Emission Standards for Radon Emissions From Operating Mill Tailings (40 CFR 61.250 through 61.256), promulgated December 15, 1989, under the Clean Air Act. The emission limit under 40 CFR 61.252(a) for radon-222 is 20 picoCuries per square meter per second (pCi/m2-sec). 3. 40 CFR 61.253 requires that compliance with the emission limit be determined annually through the use of 40 CFR Part 61, Appendix B, Method 115. 4. Method 115 specifies that certain categories of land areas ("regions") of the tailings pile be monitored with largearea activated charcoal collectors. MeasureMentS shall not be made within 24 hours of rainfall or when the temperature is below 35 degrees Fahrenheit. 5. To comply with 40 CFR 61.253, the Company submitted a "NESHAP Radon Flux Measurement Program" report to the EPA on March 18, 1991. The report contains calendar year 1990 radon- 222 monitoring data. The Company selected a monitoring period covering September 5, 1990 through September 11, 1990, to constitute the annual compliance testing for 1990. EPA has reviewed the report and has determined that the monitoring was ir accordance with Method 115. Results are shown below. 2 DEQ000239 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 109 of 156 UMETOO WRITE MESA MILL ANNUAL COMPLIANCE TESTING FOR 1990 FUKRADON-222 WNITORIM PERIOD: 9/5/90 TOMB 9/11190 Region Designation (NESHAP) Corresponding Cell 2 Region Designation (Cannany) Argatm?)

This exceeds the radon-222 emissions standard of 20 pCi/m2-sec. 7. Under 40 CFR 61.254(b), if the radon-222 emission limit is exceeded, the Company must begin submitting monthly corrective action progress reports ("Compliance Reports") to the EPA. The first such Compliance Report submitted to EPA was dated April 24, 1991, and addressed Cell 2. EPA has reviewed this report and has found that it lacks deadlines for corrective action and retesting at Cell 2. CONCLUSIONS OF LAW The Company is violating the radon-222 emissions standard of 40 CFR 61.252(a) at Cell 2. 3 DEQ000240 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 110 of 156 ORDER 1.

Environmental Protection Agency Region VIII 999 18th Street - Suite 500 Denver, Colorado 80202-2405 Attention Mr. Michael Owens Re: Compliance Order Docket No. CAA-113-91-05 Dear Mr. Dickstein: The following is the Compliance Report for the month of July, 1991 pursuant to the above referenced order. The following table shows complianc4 steps with completion dates, to bring Cell 2 at the White Mesa Mill to below 20 pCi/re/sec. Completion Date Activity 1. Contractor Mobilization July 6, 1991 2. Construction August 16, 1991 3. Measure Radon August 30, 1991 4. Prepare/Review Report September 30, 1991 The contractor began construction Monday July 15. The contractor's schedule submitted to Umetco shows completion on August 16 (six total weeks including mobilization) for the placement of 120,000 cubic yards of random fill over 18.1 surface acres. As you know, safety is of prime concern on this job as we are working on unconsolidated tailings and slimes. Due to the soft nature of the tailings sands, one of the contractor's trucks broke through the cover during the first week of construction. To ensure that this would not happen again the thickness of the cover was increased to support the construction equipment. Repeated attempts to reduce the thickness back down to design have not been successful. As of Monday, August 12, SEM Construction had placed 90 M cubic yards but had only covered 43 M square yards of area. This equates to an average thickness in place of 6.25 feet versus a design of 4.0 feet. OFFICIAL [CCKE COPY pp DEQ_NRC000613 Case 2:14-cv-00243-CW-BCW Document 63-5 Filed 04/27/16 Page 114 of 156 Since the start of construction on July 15th, we have lost two work days due to rain-induced wet conditions on the cover. Nevertheless, SEM is meeting their schedule for fill placement rates. In order to make up for the unexpected additional volume of cover, Umetco has mobilized its own fleet of 35 ton rock trucks which will work in areas of the tailing where their weight can be supported. Current estimates are that these units will place an additional 30 M cubic yards over what the contractor can place before the end of the construction phase. As shown on the attached Gantt chart, fill placement is scheduled to continue through the end of August and will terminate on September 7. At completion of the construction phase, approximately 200 M cubic yards of fill will have been placed over an area of approximately 24 acres. The main reason for the increase in cover area is the addition of the NRC permitted dump along the north dike. This area had numerous radon "spikes" within its perimeter and we have since determined that any attempt to control radon would have to include this area. Umetco is in the process of permitting a new dump area with the USNRC. The radon measurement contract has been awarded to Scientific Analysis. They are currently scheduled to begin on September 4, 1991 with completion of Cell 2 and Cell 3 radon measurements by September 9, 1991. It therefore appears that Umetco will still be able to meet the deadline of October 31, 1991 as required by the Compliance order. We will continue to keep your staff appraised of significant changes in our schedule as they become known to us.

The following table shows the compliance activities to date. Activity Completion Date 1. Contractor Mobilization COMPLE ED 2. Construction COMPLETED 3. Measure Radon COMPLETED 4. Prepare/Review Report September 30, 1991 As stated in the previous monthly reports, the contractor was unable to maintain the four-foot lift of random fill due to the soft nature of the tailings. The thickness of the lift necessary to support the placement equipment was above six feet. This resulted in many more cubic yards being placed to cover a given surface area. Since surface area acres covered is the primary radon reduction method for this project, Umetco dedicated more resources to the project, both men and equipment. Two Cat 769 trucks, two bottom-dump tractor-trailer trucks, a Cat D-7 crawler, a Cat D-6 crawler, and two Cat 980 loaders worked on cover placement. The original project scope called for the placement of 120,000 cubic yards. By the end of construction, the contractor had moved approximately 175,000 cubic yards with Umetco moving an additional 50,000 cubic yards. As witnessed by Dr. Milton Lammering and Mr. Robert Tauer, radon measurements commenced September 5, 1991. Due to rainfall, measurements were delayed and not completed until September 9, 1991. Preliminary results are expected by September 20, 1991, and will be communicated to Dr. Lammering and Mr. Michael Owens of your staff. Ihnetco expects that the actions taken to date will result in compliance with the 20 pCi/m /sec in both Cells 2 and 3.
