These monitoring programs were developed and implemented at the time of Mill construction, operated with appropriate adaptation over time, and are consistent with the Mill's State of Utah Radioactive Materials License No. UT1900479 (the "License") and guidelines developed by the United States Nuclear Regulatory Commission ("NRC") (NRC Regulatory Guide 4.14, Radiological Effluent and Environmental Monitoring at Uranium Mills-Rev. 1, ML003739941), 1980). 1.1 Modifications to the Monitoring Programs As stated above, the monitoring programs implemented to date are consistent with the Mill's License and guidelines developed by the NRC and described in Regulatory Guide 4.14. The Mill's License modifies and expands the effluent monitoring programs implemented at the Mill beyond what is regularly required by NRC Regulatory Guide 4.14. Specific changes to the individual monitoring programs are discussed in the subsequent sections of this report. In a letter dated July 23, 2014, DWMRC stated that because "Tailings Cell 2 is no longer in operation (receiving tailings), the Division of Air Quality and the Division of Radiation Control agree that Subpart W NESHAPs requirements (40 CFR Part 61) no longer apply; however, at this phase of cell 2 closure activities, the requirements of 10 CFR Part 40, Appendix A, Criterion 6 do apply." The July 23, 2014 letter further requires that radon flux measurements for Cell 2 be collected semi-annually in accordance with methodology specified in 40 CFR Part 61, Appendix B, Method 115 and that the measured results be included in the Semi-Annual Effluent Reports submitted to DWMRC. As a result of the July 23, 2014 letter, Cell 2 radon flux monitoring data are reported herein. Additional details regarding the monitoring and data collection activities for the Cell 2 radon flux are included in Section 9.0. As specified by the License and the documents described above, the Mill monitors the following environmental media and conditions: a) Airborne particulate radionuclide concentrations obtained from the following sampling stations: • North, east and south of the Mill Site: BHV-1, BHV-2, and BHV-8 (north), BHV-5 and BHV-7 (east), and BHV-4 (south). BHV-1 and BHV- 8 serve as surrogates for the nearest resident (BHV-1 and BHV -8 are 1 approximately 1.2 miles north of the Mill, but approximately 0.4 miles closer to the Mill than the nearest resident); • A background location distant to and west of the Mill (BHV-3) that was monitored for airborne particulates up until November, 1995 (at which time background was established), which is no longer monitored for air particulates; and • A station specifically requested by the White Mesa Ute Community south of the Mill Site (BHV-6); b) External ( direct) gamma radiation measured at air monitoring stations BHV-1, BHV-2, BHV-3, BHV-4, BHV-5, BHV-6, BHV-7, and BHV-8; c) Vegetation at three site periphery locations, for uptake of radionuclides; d) Stack release rates from the Mill's air emissions sources; e) Surface water at Cottonwood Creek and, when flowing, Westwater Creek, both located west of the Mill; f) Soil radionuclide activity during the third quarter of each year; g) Radon-222 at the air particulate monitoring stations (BHV-1 through BHV-8); h) Meteorological conditions; i) Radon flux of the Cell 2 cover as specified by the DWMRC in correspondence dated July 23, 2014; j) Groundwater (up and down gradient) of the Mill facility; and 1 k) Seeps and springs in the vicinity of the Mill. 1 This semi-annual effluent report provides the results of the specific monitoring and sampling activities that were undertaken during the subject reporting period. 2.0 ENVIRONMENTAL AIR PARTICULATE SAMPLING 2.1 Program Overview Prior to 2014, the environmental airborne particulate monitoring program at the Mill utilized four air sampling stations. Four high-volume continuous air sampling stations (BHV-1, BHV-2, BHV-4, and BHV-5) were required by the License. In addition to these 1 Groundwater sampling and seeps and springs sampling are reported separately pursuant to the Mill's State of Utah Ground Water Discharge Permit No. UGW370004, and are not included with this report. 2 four environmental air sampling locations, an additional station (BHV-6) was installed at the request of the White Mesa Ute Community. This station began operation in July of 1999 and provides airborne particulate information in the southerly direction between the Mill and the White Mesa Ute Community. As stated in Section 1.1 above, the air pruticulate monitoring program has expanded to include the following: • The addition of two air monitoring stations (BHV-7 and BHV-8); • The addition of thorium-232 ("Th-232") to the list of air particulate analytes; These sampling stations serve as sentinels for airborne particulate which could potentially emanate from the Mill site. In addition to its general site monitoring function, BHV-1 and BHV-8 also serve as conservative surrogates for concentrations at the nearest resident, because they are located approximately 1.2 miles north of the Mill just south of the nearest resident but between the Mill and that resident. With regard to background monitoring, the Mill previously operated a continuous high- volume air sampling station (BHV-3) which was located 3.5 miles west of the Mill site. With the approval of NRC, this station (BHV-3) was removed from the active air monitoring program in November 1995. At that time, NRC determined that a sufficient air monitoring database had been compiled at BHV-3 to establish a representative airborne radionuclide background for the Mill. The NRC approval to remove BHV-3 from the active air monitoring program specified background radionuclide concentrations based on the historic data. These concentrations are shown on the graphs and tables in Tab B3. While air sampling was discontinued at this location, gamma measurements, radon measurements and soil sampling continue at BHV-3. 2.2 Sampling Protocol and Analytical Results Airborne particulate monitors are operated continuously at each of the high-volume air sampling stations except BHV-3. As noted above, BHV-3 was removed from the active air monitoring program in November 1995, but the NRC specified background concentrations are shown in Attachment B. Particulate sample collection filters are gathered by site technicians weekly in accordance with the Mill's environmental air sampling procedures and are composited on a quarterly basis for laboratory analyses. The collected filters are analyzed for Unat activity, Th-230 activity, Ra-226 activity, Th-232 activity and Pb-210 activity. Fugitive dust standards for the facility are limited by the Mill's State of Utah Air Approval Order. The specific locations of the Mill's airborne particulate monitoring stations are depicted on the figure entitled Particulate Monitoring Stations included as Attachment A. Station BHV-3, which is no longer sampled for air particulates, is located approximately 3.5 miles west of the Mill facility. 3 The analytical results of radionuclide particulate sampling for each monitoring station operated during this reporting period are provided in Attachment B under separate sampling station attachment tabs (Tabs 1-8). Each tab contains graphical illustrations of the radionuclide concentrations in log-scale presentation format. The graphs display reported data over time since the 1981 inception of the Mill's environmental air particulate monitoring program or the installation of the locations, whichever is appropriate. The actual analytical results (and associated QA/QC information) reported by the laboratory for the reporting period are provided under Attachment C. In addition to the analyses for radionuclides, particulate loading is determined for each filter and composited as a quarterly mass-loading estimate for review purposes only. Graphs showing particulate loading at each station and the underlying data are included as Attachment D. Analytical data were reviewed against the laboratory established acceptance limits specified in the data packages. The analytical data are usable for their intended purpose. Any deviations noted did not affect the quality or usability of the data. For graphical illustration purposes, values reported at zero, values reported at less than the prescribed detection limit(< 1 x 10-16 uCi/ml), and missing values were plotted as 1 x 10-16 uCi/ml concentrations. Where other "less than" values were indicated (i.e., where detection limits for the data varied from 1 x 10-16 uCi/ml), the detection limit concentration was utilized for plotting the data point. This graphing convention is not utilized to formulate station average information, nor is it intended as a precedent for data treatment. Rather, the intent is to provide a conservative viewable depiction of site airborne radionuclide information. This is considered to be a conservative approach, because the actual concentration below the detection limit cannot be determined and, as a result, the plotted point will be at the same or a higher concentration than the actual activity concentration of the collected sample. 2.3 General Observations The results of environmental air monitoring for this semi-annual period indicate that for all radionuclides at all monitoring stations, airborne radionuclide particulate activity concentrations were well below regulatory Effluent Concentration Limits ("ECL's") and the Mill's ALARA goals, which are set at 25% of the ECLs, except as noted below. It is notewmthy and expected that Pb-210 concentrations are elevated when compared to the other parent radionuclide concentrations (i.e. U-nat, Th-230 and Ra-226). This phenomenon is due to the well-established controlling effect experienced worldwide as a result of the ubiquitous presence of radon in the earth's atmosphere. Accordingly, the elevated Pb-210 presence in disequilibrium with parent radionuclides measured here is not associated with uranium milling operations. Rn-222 emanates as a decay-chain progeny of the Ra-226 contained in the soil of the earth's crust and is dispersed generally throughout the earth's atmosphere. The electrically charged short and long-lived decay products of Rn-222 attach to ambient dust particles found naturally in the atmosphere and 4 are carried with the air. Pb-210 is the longest lived of these decay products and is the decay product of the shorter-lived radon progeny. As such, it accumulates as an electrical attachment on the natural ambient dust in the atmosphere and is generally measured at elevated activity when compared to local decay-chain parent radionuclide activity, regardless of uranium milling activity. At the Mill's BHV air monitoring stations, all dust (ambient natural and mill derived) is collected by the sample filter. Because of the natural elevation of Pb-210 accumulated as an attachment to the naturally occurring ambient dust particles collected by the air sampling equipment, Pb-210 is commonly elevated and in disequilibrium when compared to parent radionuclide activity, regardless of the Mill's presence. By way of illustration, average ground-level concentrations have been reported for selected States (NCRP Report 94, 1992) and are summarized in Table 1 in the Tables Tab of this report, demonstrating that elevated Pb-210 activity is present where no uranium milling operations are located nearby. In April 1977, prior to Mill construction and Mill operations, air particulate Pb-210 was measured at the Mill site to be 1.3E-14 uCi/ml (13.0E-3 pCi/m3)2. 2.4 Site Specific Sampling Data The results of airborne particulate monitoring for the period (without background subtraction) are provided by sampling station and radionuclide in Tables 2 through 6 in the Tables Tab of this report. Along with these data, the tables present comparative ECL' s and the ECL percentage measured at each of the monitoring stations sampled during the period. A review of these data support the conclusion that airborne particulates are well controlled at the Mill. In all cases, the measured activity concentrations were well within the ECL, as well as the Mill's ALARA goal (i.e. 25% of the ECL). Lower Limits of Detection consistent with NRC Regulatory Guide 4.14 were maintained by the Mill's contract analytical laboratory for this reporting period. The data obtained since program inception in 1981 indicates that only one individual quarterly measurement (Th-230 at BHV-5 for the 2nd Quarter of 1996) has ever exceeded the ECL at the Mill. While it is important to consider and evaluate an individual measurement exceeding the ECL, it is the average annual concentration that is of primary significance for public dose estimation purposes. In that instance, the average annual concentration of Th-230 for BHV-5 in 1996 was well below the ECL. Data obtained since program inception in 1981 also indicate that, with very few exceptions, the gross (background inclusive) measurements do not exceed the site's ALARA goal (i.e. only ten of the several thousand total gross radionuclide determinations to date exceeded the Mill's self-imposed 25% ALARA goal). 2 See the Environmental Report, White Mesa Uranium Project, San Juan County, Utah for Energy Fuels Nuclear, Inc. prepared by Dames & Moore, January 30, 1978, Section 2.9.1.1 5 2.5 Radon-222 With the approval of the NRC, Radon-222 monitoring at BHV stations at the Mill was discontinued in 1995 due to the unavailability of monitoring equipment to detect the revised 10 CFR Part 20 standard. Instead, compliance with these limits and the requirements of R313-15-301 was demonstrated by a calculation, authorized by the NRC and as contemplated by R313-15-302(2)(a) which states "A licensee or registrant shall show compliance with the annual dose limit in Section R313-15-301 by: (a) Demonstrating by measurement or calculation that the total effective dose equivalent to the individual likely to receive the highest dose from the licensed or registered operation does not exceed the annual dose limit;". This calculation is performed by use of the Mll...DOS code for estimating environmental radiation doses for uranium recovery operations. R313-15-302(2)(a) contemplates demonstrating compliance either through modeling or measurement. In order to determine whether or not detection equipment has improved since 1995, EFRI voluntarily began ambient Radon-222 monitoring at the BHV stations in 2013. The Radon-222 data collected from 2013 through present are presented in Attachment J. As stated in Section 1.1 above, the Mill's effluent monitoring programs were expanded in 2014. The expanded monitoring programs require the collection of Radon-222 data at all of the BHV stations. For the BHV stations EFRI calculated ECLs using methodology shown in Attachment J. The calculated ECLs for all of the BHV stations are included on the data table included in Attachment J. The radon-222 results are below the calculated ECLs and within the range of historic levels as shown in Attachment J. Radon-222 monitoring is completed using detectors with an effective reporting limit of 0.06 pCi/L. Field blank detectors are collected quarterly and the results (with background included) are included in Attachment J. During the reporting period, one field blank was collected during each quarter. Field blanks are opened at the beginning of the monitoring period and immediately sealed in the manufacturer supplied packaging. The field blanks are stored in the environmental office until the end of the monitoring period, when they are packaged with the field samples and shipped to the laboratory for processing. While relatively low concentrations were reported for the field blanks, the field blank data show detections which are greater than the highest detection reported for any of the samples collected at the high volume stations. The field blank data have been consistently higher than the samples. Despite the detections reported for the field blanks, there is no indication that the results reflect contamination during shipping. If the detections on the field blanks indicated contamination resulting from shipment, then all of the detectors would be affected in the same manner and the sample data are below the field blank levels. It appears that the field blanks have been affected by the storage prior to shipping. EFRI is conducting an investigation into the possible causes of the anomalous field blank detections. 6 3.0 EXTERNAL RADIATION (DIRECT GAMMA) Gamma exposure rate estimates were measured for the repmting period utilizing optically stimulated luminescence dosimeters ("OSLs"). Previously, these dosimeters were located at each of the Mill's high-volume air sampling stations (BHV-1, BHV-2, BHV-4, BHV-5 and BHV-6) and at the designated background monitoring station (BHV-3). As noted in Section 1.1 of this report, the effluent monitoring programs at the Mill were expanded to include expansion of the gamma exposure monitoring program through the addition of gamma monitoring at the two new air monitoring stations (BHV-7 and BHV - 8). Measurements obtained from location BHV-3 have been designated as background due to BHV-3's remoteness from the Mill site (i.e., BHV-3 is located approximately 3.5 miles west of the Mill site). The results of the environmental OSL measurements and semi- annual cumulative above-background data are provided in Table 7 in the Tables Tab of this repmt. In addition, measurement data obtained at these locations are graphically presented in Attachment E to this report. The results for this period indicate that above background measurements for stations BHV-2, BHV-4, BHV-5, BHV-6, BHV-7, and BHV-8 are within historic levels. The BHV-1 fourth quarter rnrem data (with background subtracted) is 9.9 rnrem, which is higher than the majority of the historic levels for that station. BHV-1 and BHV-8 are at the location of the nearest potential residence. The nearest actual residence is approximately 0.4 miles north of BHV-1 and BHV-8. The annual limit for an individual member of the public is 100 mrem/yr for combined internal and external exposure. The BHV -1 2019 results were consistent for the first through third quarters with an above background value of approximately 5 mrem per quarter. The fourth quarter result was higher than the first three quarters of 2019, indicating that the fourth quarter result is likely anomalous. The fourth quarter result is being considered anomalous because Mill activity in 2019 was consistent and similar activities were conducted all year. There were no activities in the fourth quarter that would have contributed to this variance. Further, by comparison to BHV-8, which is due west of BHV-1 and somewhat closer to the Mill facility, BHV-8 had reported values of 0.2 mrem above background for the third quarter and O mrem above background for the fourth quarter. The dose at BHV-8 is significantly lower (approximately 1 %) of the dose at BHV-1. A review of the air particulate data indicates that air particulate for the fourth quarter was higher at BHV-8 than at BHV-1, ruling out air particulate as being the cause of this difference. As noted above, BHV-1 is located at the nearest potential resident. Future results will be reviewed and used to determine if additional activities are necessary. In addition, the OSL results and the laboratory will be investigated to assure results are representative of actual conditions. 7 4.0 VEGETATION SAMPLES The NRC Regulatory Guide 4.14 requires that three samples be collected during the grazing season, without specifying exact months or times during the season. Two samples were collected during the January through June reporting period. The third sample was be collected on November 13, 2019. As noted in Section 1.1, Amendment 7 and the associated RFI expanded the vegetation sampling program through the addition of Th- 232 and U-Nat. During the January through June reporting period, samples were collected on April 25, and June 6, 2019. During the July through December reporting period, a sample was collected on November 13, 2019. The data from the sampling events are included in Attachment F. Graphical log-scale presentation of the vegetation sampling results, together with the analytical results reported by the Mill's contract laboratory (including QA/QC information) for this sampling period, are included as Attachment F of this report. The 2019 data results are within the variation of previous sampling episodes. Analytical data were reviewed against the laboratory established acceptance limits specified in the data packages. The analytical data are usable for their intended purpose. Any deviations noted did not affect the quality or usability of the data. The value in the MDC column in the data package is the sample-specific minimum detectable concentration ("MDC"). The MDC is based on the sample moisture, composition and other sample-specific variables. The lower limit of detection which is a limit representing the detection capability of the measurement system is referred to as the Reporting limit ("RL") in the data package. 5.0 STACKSAMPLING Under Section 5.0 of Tab 1.4 of the Mill's EPM gas stack samples are collected at the Mill in accordance with the schedule shown below: 8 Stack Sampling Requirements Grizzly North and/or Yellowcake Vanadium South Packaging Vanadium Frequency Baghouse Yellowcake Baghouse Dryer Stack Packaging Stack Dryer Stacks Stack Stack Quarterly If operating, If operating, If operating, If operating, If operating, U-nat, Th-U-nat, Th-U-nat, Th-U-nat, Th-U-nat, Th- 230, Ra-226, 230, Ra-226, 230, Ra-226, 230, Ra-226, 230, Ra-226, Pb-210, Th-Pb-210, Th-Pb-210, Th-Pb-210, Th-Pb-210, Th- 232, Ra-228, 232, Ra-228, 232, Ra-228, 232, Ra-228, 232, Ra-228, and Th-228. and Th-228. and Th-228. and Th-228. and Th-228. The south yellowcake dryer and yellowcake baghouse did not operate during the reporting period. The north yellowcake dryer has not been in operation since the third quarter of 2012, and therefore, has not been sampled since it was last in operation. The vanadium dryer and vanadium baghouse operated during the reporting period. Vanadium stack samples were collected from the vanadium dryer and packaging baghouse during third and fourth quarter. The analytical results of stack sampling conducted in the reporting period, as well as for the previous two quarters, are provided in Table 9 in the Tables Tab of this report. The actual analytical results reported by the laboratory for the reporting period (third and fourth quarters 2019) are provided in Attachment G to this report. It is also important to note that uranium stack effluent concentrations are not comparable to environmental air sampling station ECLs for regulatory compliance purposes. The ECL is a limit that applies to the receptor locations and is not applicable to effluents from mill processes on the Mill site. These stack release data are more appropriately utilized for dose modeling purposes, and dose modeling is not computed for semi-annual reporting purposes. Analytical data were reviewed against the laboratory established acceptance limits specified in the data packages. The analytical data are usable for their intended purpose. Any deviations noted did not affect the quality or usability of the data. 6.0 SURFACE WATER MONITORING Under the License, Part 11.2 B surface water samples are required to be obtained annually from Westwater Canyon and semi-annually from Cottonwood Creek. Sediment samples from Westwater Canyon are taken in place of the Westwater Canyon surface water sample where surface water is not available for sampling. Westwater Canyon 9 surface water was sampled in the first quarter of 2019. The Westwater data are included in the SAER for January -June 2019, which was submitted on August 21, 2019. The Mill's EPM requires that samples from Cottonwood Creek be analyzed for TDS and total suspended solids ("TSS") quarterly, and the License, Part 11.2 B requires that samples from Cottonwood Creek be analyzed for dissolved and suspended radionuclides including Gross Alpha, U-nat, Ra-226, and Th-230 semi-annually. In accordance with these requirements, Cottonwood Creek was sampled for TDS and TSS and dissolved and suspended radionuclides during the fourth quarter. No sample was collected during the third quarter because there was no water present during the quarter. The field data sheets for the surface water sampling events, along with graphs showing historic results are included as Attachment H. Analytical data were reviewed against the laboratory established acceptance limits specified in the data packages. No data issues were noted and the data are usable for the intended purpose. 7.0 SOIL SAMPLING As mentioned in Section 1.1 above, specific changes to the individual monitoring programs have been made. In accordance with the Mill's EPM, 52 surface soils were collected in August 2019. The soil samples were analyzed, on a dry basis, for Ra-226, U-nat, Pb-210, and Th-232. The results of these samplings indicate that soil activity levels at the air monitoring stations remain low and within the range of historic levels. A graphical presentation of the soil results, together with analytical sample results for the August 2019 sampling event are provided in Attachment I. Analytical data were reviewed against the laboratory established acceptance limits specified in the data packages. The analytical data are usable for their intended purpose. Any deviations noted did not affect the quality or usability of the data. Field duplicate sample results were assessed as required by the SOP. Duplicate results were within the acceptance limits specified in the SOP except as noted in Table 1-3. Field duplicate results are shown in Attachment I. 8.0 METEOROLOGICAL MONITORING As in prior reporting periods, an independent contractor has prepared the White Mesa Mill Semi-annual Meteorological Monitoring Report for the reporting period. This information is retained at the Mill site for agency review. 10 9.0 CELL 2 RADON FLUX The July 23, 2014 letter, DWMRC stated that because "Tailings Cell 2 is no longer in operation (receiving tailings), the Division of Air Quality and the Division of Radiation Control agree that Subpart W NESHAPs requirements (40 CFR Part 61) no longer apply; however, at this phase of cell 2 closure activities, the requirements of 10 CFR Part 40, Appendix A, Criterion 6 do apply." Further, the DWMRC July 23, 2014 letter states that "since the MILDOS-Area Models that have been run to show compliance with dose limits for releases from the Mill were based on a limit of 20 picocuries per square meter second (pCi/m2-sec ), in order to ensure compliance with previously analyzed conditions, the DWMRC will require the licensee to continue to measure the radon flux in accordance with [the latest revision of] 40 CFR 61, Appendix B, Method 115, "Monitoring for Radon-222 Emissions". The measured radon flux for Cell 2 shall not exceed a value of 20 (pCi/m2-sec) until a new MILDOS- Area Model to analyze a higher radon flux is completed and demonstrates compliance with dose limits based on the releases from the Mill. As required by Method 115, a minimum of 100 measurements are required and shall be performed on a semi-annual basis." Per the requirements detailed above, EFRI sampled Cell 2 radon flux in April 2019 for the January through June 2019 reporting period and in October for the July through December reporting period. The April 2019 measurement was 0.4 pCi/(m2-sec). The October 2019 measurement was 2.3 pCi/(m2-sec). Both of the 2019 measurements were below the 20.0 pCi/(m2-sec) standard. The full data report for the October 2019 Cell 2 radon flux sampling is provided in Attachment K. The full data report for the April 2019 Cell 2 radon flux sampling is provided in Attachment K of the January through June SAER which was submitted on August 21, 2019. The 2019 average radon flux is 1.35 pCi/(m2-sec) which is the arithmetic average of the April 2019 measurement of 0.4 pCi/(m2-sec) and the October measurement of 2.3 pCi/(m2-sec). The arithmetic average is below the 20.0 pCi/(m2-sec) standard. It is important to note that Cell 2 Phase 1 cover placement/construction commenced in April 2016 and was completed in April 2017.

SAMPLE TEMPERATURE COMPLIANCE: 4°C (±2°C) Report Date: 11 /11 /19 CASE NARRATIVE Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand delivered immediately after collection shall be considered acce1ptable if there is evidence that the chilling process has begun. GROSS ALPHA ANALYSIS Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by this method for non potable waters should be viewed as inconsistent. RADON IN AIR ANALYSIS The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to beginning of counting should not exceed 8 days. SOIUSOLID SAMPLES All samples reported on an as received basis unless otherwise indicated. ATRAZINE, SIMAZINE AND PCB ANALYSIS Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven individual Aroclors. When the results for all seven are ND (not detected), the sample meets EPA compliance criteria for PCB monitoring. SUBCONTRACTING ANALYSIS Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the Laboratory Analytical Report.

SAMPLE TEMPERATURE COMPLIANCE: 4°C (±2°C) Report Date: 02/13/20 CASE NARRATIVE Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun. GROSS ALPHA ANALYSIS Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by this method for non potable waters should be viewed as inconsistent. RADON IN AIR ANALYSIS The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to beginning of counting should not exceed 8 days. SOIUSOLID SAMPLES All samples reported on an as received basis unless otherwise indicated. ATRAZINE, SIMAZINE AND PCB ANALYSIS Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven individual Aroclors. When the results for all seven are ND (not detected), the sample meets EPA compliance criteria for PCB monitoring. SUBCONTRACTING ANALYSIS Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize its branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the Laboratory Analytical Report.

Appendix E lV INTRODUCTION Test Purpose This test project was conducted to determine the total radionuclide emissions from the Vanadium Dryer and the Vanadium Packaging exhaust stacks. Emissions are calculated in terms of pico curies per dry standard cubic foot (pCi/dscf) and pico curies per hour (pCi/hr). Test Location and Type of Process Energy Fuels Resources is located about 5 miles south of Blanding, Utah. Vanadium containing material is processed and packed into barrels which are shipped to other facilities for additional processing. A scrubber serves as the main emission control device for the vanadium dryer. A baghouse serves as the control device for the vanadium packaging area. Stack schematics are shown as Figures 1 and 2 in Appendix D. Test Dates Run 1 on the Vanadium Dryer and run 1 on the Vanadium Packaging exhausts were completed August 20, 2019. The second test runs were completed August 21, 2019. Pollutants Tested and Methods Applied These tests were a determination of radionuclide emissions in accordance with EPA Method 5/114. Test run filters and front wash residues were sent to Inter-Mountain Labs in Sheridan, Wyoming. Test Participants Energy Fuels TETCO Logan Shumway Mike McNamara Reed Kitchen 1 Steve Snyder Doug Olsen Deviations from EPA Methods None. Quality Assurance Testing procedures and sample recovery techniques were according to those outlined in the Federal Register and the Quality Assurance Handbook for Air Pollution Measurement Systems. 2 SUMMARY OF RESU LTS Emission Results Table I presents the findings of the test in Curies per dry standard cubic foot.

Two, four-inch diameter sample port were located 9.67 diameters (29 feet) downstream from the last disturbance and 3.33 diameters (10 feet) upstream from the next disturbance. Figure 1 in Appendix Dis a schematic of the stack. The inside diameter of the Vanadium Packaging exhaust stack was 29.5 inches. Two, four-inch diameter sample ports were located 3.29 diameters (9 inches) downstream from the last disturbance and more than 6.78 diameters (200 inches) upstream from the last disturbance. The sample port locations are depicted in Figure 2 in Appendix D. Sampling Point Location Table III shows the distance of each sampling point from the inside wall according to EPA Method 1. Each point was marked and identified with a wrapping of glass tape and numbered. These points were determined by measuring the distance from the inside wall.

The sample consoles used to conduct Methods 1-5/114 were constructed to meet the specifications outlined in the CPR. The temperature sensors were K-type thermocouples. Heater, vacuum, and pitot line connections were designed to be interchangeable with all units used by the tester. A 316 stainless steel probe liner was used for the tests. Figure 3 in Appendix E is a sketch of the Methods 5/114 sampling train. Sample boxes were prepared for testing by following the prescribed procedures outlined in Methods 5/114. Sampling and Analytical Procedures All sampling and analytical test procedures were as specified in 40 CPR 60, Appendix A, Methods 5/114. Quality Assurance All equipment setup, sampling procedures, sample recovery, and equipment calibrations were carried out according to the procedures specified in 40 CFR 60 and the Quality Assurance Handbook for Air Pollution Measurement Systems. 7 APPENDICES A: Complete Res~lts and Sample Calculations B: Raw Field Data C: Laboratory Data and Chain of Custody D: Raw Production Data E: Calibration Procedures and Results F: Related Correspondence 8 APPENDIX A Table IV Complete Results, Vanadium Dyer Table V Complete Results, Vanadium Packaging Nomenclature Sample Equations A TABLE IV COMPLETE RESULTS ENERGY FUELS CORPORATION, BLANDING, UT AH VANADIUM DRYER dryer Symbol DescriEtion Dimensions Run#l Run#2 Date 8/20/19 8/21/19 Filter# 7204 7206 Begin Time Test Began 7:42 7:46 End Time Test Ended 15:45 15:47 Pbm Meter Barometric Pressure In.

Appendix E iv INTRODUCTION Test Purpose This test project was conducted to determine the total radionuclide emissions from the Vanadium Dryer and the Vanadium Packaging exhaust stacks. Emissions are calculated in terms of pico curies per dry standard cubic foot (pCi/dscf) and pico curies per hour (pCi/hr). Test Location and Type of Process Energy Fuels Resources is located about 5 miles south of Blanding, Utah. Vanadium containing material is processed and packed into barrels which are shipped to other facilities for additional processing. A scrubber serves as the main emission control device for the vanadium dryer. A baghouse serves as the control device for the vanadium packaging area. Stack schematics are shown as Figures I and 2 in Appendix D. Test Dates Run I on the V anadiwn Dryer and run I on the Vanadium Packaging exhausts were completed October 28-29, 2019. The second test runs were completed October 29-30, 2019. Pollutants Tested and Methods Applied These tests were a determination of radionuclide emissions in accordance with EPA Method 5/114. Test run filters and front wash residues were sent to Inter-Mountain Labs in Sheridan, Wyoming. Test Participants Energy Fuels TETCO Logan Shumway Mike McNamara Reed Kitchen 1 Steve Snyder Doug Olsen Deviations from EPA Methods None. Quality Assurance Testing procedures and sample recovery techniques were according to those outlined in the Federal Register and the Quality Assurance Handbook for Air Pollution Measurement Systems. 2 SUMMARY OF RESULTS Emission Results Table I presents the findings of the test in Curies per dry standard cubic foot. Tables IV and Vin Appendix A have more detailed information. Table I.

All pertinent process data was available for recording by agency personnel. Production data was retained by Energy Fuels Resources. Description of Collected Samples The test filters for the Vanadium Dryer were heavily covered with a dull, lime green colored particulate. The front washes were clear in appearance. The test filters for the Vanadium Packaging exhaust were moderately covered with Dark Brown colored particulate matter. The front washes were brown in appearance. Discussion of Errors or Irregularities None Percent lsokinetic Sampling Each test run was isokinetic within the ±10% of 100% criterion specified in the Federal Register. Isokinetic values for each test run are presented in Table II. 3 1 98 101 2 97 99 4 SOURCE OPERATION Process Control Devices Operation All process control devices were operated normally. Recorded scrubber pressure drop and water flow rate readings are found in Appendix D. Process Representativeness The facility was operated normally. Production data was retained by Energy Fuels Resources. 5 SAMPLING AND ANALYTICAL PROCEDURES Sampling Port Location The inside diameter of the Vanadium Dryer exhaust stack was 36 inches. Two, four-inch diameter sample port were located 9.67 diameters (29 feet) downstream from the last disturbance and 3.33 diameters (10 feet) upstream from the next disturbance. Figure 1 in Appendix Dis a schematic of the stack. The inside diameter of the Vanadium Packaging exhaust stack was 29.5 inches. Two, four-inch diameter sample ports were located 3.29 diameters (9 inches) downstream from the last disturbance and more than 6.78 diameters (200 inches) upstream from the last disturbance. The sample port locations are depicted in Figure 2 in Appendix D. Sampling Point Location Table III shows the distance of each sampling point from the inside wall according to EPA Method 1. Each point was marked and identified with a wrapping of glass tape and numbered. These points were determined by measuring the distance from the inside wall.

The sample consoles used to conduct Methods 1-5/114 were constructed to meet the specifications outlined in the CFR. The temperature sensors were K-type thermocouples. Heater, vacuum, and pitot line connections were designed to be interchangeable with all units used by the tester. A 316 stainless steel probe liner was used for the tests. Figure 3 in Appendix Eis a sketch of the Methods 5/114 sampling train. Sample boxes were prepared for testing by following the prescribed procedures outlined in Methods 5/114. Sampling and Analytical Procedures All sampling and analytical test procedures were as specified in 40 CFR 60, Appendix A, Methods 5/114. Quality Assurance All equipment setup, sampling procedures, sample recovery, and equipment calibrations were carried out according to the procedures specified in 40 CFR 60 and the Quality Assurance Handbook for Air Pollution Measurement Systems. 7 APPENDICES A: Complete Results and Sample Calculations B: Raw Field Data C: Laboratory Data and Chain of Custody D: Raw Production Data E: Calibration Procedures and Results F: Related Correspondence 8 APPENDIX A Table IV Complete Results, Vanadium Dyer Table V Complete Results, Vanadium Packaging Nomenclature Sample Equations A TABLEN COMPLETE RESULTS ENERGY FUELS CORPORATION, BLANDING, UT AH VANADIUM DRYER dryer Symbol Description Dimensions Rllll #1 Run#2 Date 10/28-29/19 10/29-30/19 Filter# 7270 7223 Begin Time Test Began 16:20 13:53 End Time Test Ended 13:12 12:28 Pbm Meter Barometric Pressure In.

All samples were received and analyzed within the EPA recommended holding times, except those noted below in this case narrative. Samples were analyzed using the methods ouUined in the following references: "Standard Methods For The Examination of Water and Wastewater", approved method versions Test Methods for Evaluating Solid Waste, PhysicaUChemical Methods, SW-846, 3rd Edition 40 CFR Parts 136 and 141 40 CFR Part 50, Appendices B, J, L. and 0 Methods indicated in the Methods Update Rule published in the Federal Register Friday, May 18, 2012 ASTM approved and recognized standards All Quality Control parameters met the acceptance criteria defined by EPA and Pace Analytical (Formerly Inter-Mountain Laboratories) except as indicated in this case narrative. The uranium isotopes U234, U235, and U238 ratios are typical for the analysis of natural uranium. The quality checks for mass balance of both uranium and thorium meet expectations. The Regulatory Required Detection Limit (RRDL) was not met for thorium species due to procedureal, matrix and expected air volumes of 6,000,000 ml.

SAMPLE TEMPERATURE COMPLIANCE: 4°C (±2°C) Report Date: 09/30/19 CASE NARRATIVE Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun. GROSS ALPHA ANALYSIS Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by this method for non potable waters should be viewed as inconsistent. RADON IN AIR ANALYSIS The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to beginning of counting should not exceed 8 days. SOIUSOLID SAMPLES All samples reported on an as received basis unless otherwise indicated. ATRAZINE, SIMAZINE AND PCB ANALYSIS Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by ELI reflects the results for seven individual Aroclors. When the results for all seven are ND (not detected), the sample meets EPA compliance criteria for PCB monitoring.

Calculation of Location-Specific Effluent Concentration Limits for Radon Track Etch Monitoring Stations at White Mesa Mill Calculation Methodology For the purpose of evaluating alpha track data and compliance with the effluent concentration limit for radon, two referenced limits are listed in the regulations (10 CFR Pait 20 Appendix B, Table 2, which are incorporated by reference into R313-15-302(2)(b)(i)). One limit (lx 10-10 uCi/ml or 0.1 pCi/1) is applicable in instances where radon daughters are present with the radon, and are in 100% equilibrium with the parent Rn-222. The other listed concentration limit (1 x 10-8 uCi/ml or 10 pCi/1) is applicable when radon daughters are not present. Both limits represent the concentration at which a member of the public would receive a 50 mrem dose assuming 100% (8760 hours) occupancy. At the White Mesa Mill, the assumption of 100% equilibrium of radon progeny with parent Rn- 222 is unrealistic given the short half-lives of the nuclides considered and the short travel time to the monitoring locations. Radon emanates from the ground ( or mill tailings) without daughters present, and the daughters grow in over time. It is therefore necessary to evaluate radon daughter equilibrium at each air monitoring station utilizing site-specific wind speed and distance information to derive site-specific Effluent Concentration Limits (ECLs) for each station. Such disequilibrium situations and alternative calculations are anticipated by the regulations and, in particular, R313-15-302(3) provides a means by which the licensee may adjust the effluent concentration values in 10 CFR Part 20 Appendix B, Table 2, which are incorporated by reference into R313-15-302(2)(b)(i), to account for disequilibrium. The regulatory purpose of such an adjustment is to appropriately take into account the actual characteristics of the measured effluents, including radioactive decay equilibrium. An established (EPA, 1986) outdoor equilibrium formula to determine the appropriate Equilibrium Factor for use in calculating the ECL for disequilibrium conditions was used. The EPA expression of the outdoor Equilibrium Factor (EF) is derived by the following equation: EF = 1.0-0.0479exp(-,t4·39> _ 2.1963exp<-1138·6> + l.2442exp<-1128A> [Where: tis the travel time in minutes (distance/wind speed)] Once the Equilibrium Factor has been determined, the ECL for each air monitoring station is determined by dividing the 0.1 pCi/1 limit (for situations when daughters are present) by the Equilibrium Factor (EF). Results By utilizing the above formula, the appropriate (equilibrium adjusted) ECLs for the location was calculated. In developing the ECLs, distances and corresponding travel times have been determined by: • assuming a nominal centroid located approximately at the vanadium dryer stack, • calculating average wind speeds appropriate for each direction from the centroid to each monitoring station location, and • using Google Earth to develop the distances. Meteorological data collected at the Mill's Met Station were utilized to compute the average wind speed for different directions. These data are applicable and sufficient for the purpose of these calculations. It should be noted when comparing actual measurement values to the derived ECLs that the derived ECL provides ample protection for members of the public. More specifically, if dose calculations had been performed utilizing current ICRP 65 dose conversion conventions, the ECLs established here would represent approximately 25 mrem for continuous exposure at the monitoring stations. Therefore these values can serve as appropriate ALARA goals, since they yield doses well below the 100 mrem standard for individual members of the public.

INTRODUCTION During October 9-10, 2019 Tellco Environmental, LLC (Tellco) of Grand Junction, Colorado, provided support to Energy Fuels Resources (USA) Inc. (Energy Fuels) to conduct radon flux· measurements on Cell 2 at its White Mesa Mill site. Pursuant to Utah Department of Environmental Quality (UDEQ) requirements, Energy Fuels conducts radon flux measurements on a semiannual basis. This report presents the radon flux measurements results for Cell 2 that represent the second half of the year 2019. Tellco was contracted to provide radon canisters, equipment, and canister-placement personnel as well as lab analysis of samples collected. Energy Fuels personnel provided support for loading and unloading charcoal from the canisters. This report details the procedures employed by Energy Fuels and Tellco to obtain the results presented in Section 9.0 of this report. 2. SITE DESCRIPTION The White Mesa Mill facility is located in San Juan County in southeastern Utah, six miles south of Blanding, Utah. The mill began operations in 1980 for the purpose of extracting uranium and vanadium from feed stocks. Cell 2, which has a total area of approximately 270,624 m2, has been filled and covered. This cell is comprised of one region, a soil cover of varying thickness. There was no standing liquid and were no exposed tailings within Cell 2 during this sampling. 3. REGULATORY REQUIREMENTS FOR CELL 2 Radon emissions from the uranium mill tailings for Cell 2 at this site are regulated by the State of Utah's Division of Waste Management and Radiation Control (DWMRC). In accordance with DWMRC requirements specified in correspondence dated July 23, 2014, Energy Fuels must measure the radon flux on Cell 2 in accordance with 40 CFR 61, Appendix B, Method 115, "Monitoring for Radon-222 Emissions" semiannually. The average annual measured radon flux for Cell 2 shall not exceed a value of20 picoCuries per meter squared per second (pCi/m2-s): 4. SAMPLING METHODOLOGY Radon emissions were measured using Large Area Activated Charcoal Canisters (canisters) in conformance with 40 CFR, Part 61, Appendix B, Method 115, Restrictions to Radon Flux Measurements, (EPA, 2019). These are passive gas adsorption sampling devices used to determine the flux rate of radon-222 gas from a surface. The canisters were constructed using a 10-inch diameter PVC end cap containing a bed of 180 grams of activated, granular charcoal. The prepared charcoal was placed in the canisters on a support grid on top of a Yi inch thick layer of foam and secured with a retaining ring under 1 Yi inches of foam (see Figure 1, page 9). One hundred sampling locations were distributed throughout Cell 2 ( consisting of one region) as depicted on the Sample Locations Map (see Figure 2; Appendix D). Each charged canister was placed 1 directly onto the surface (open face down) and exposed to the surface for 24 hours. Radon gas adsorbed onto the charcoal and the subsequent radioactive decay of the entrained radon resulted in radioactive lead-214 and bismuth-214. These radon ·progeny isotopes emit characteristic gamma photons that can be detected through gamma spectroscopy. The original total activity of the adsorbed radon was calculated from these gamma ray measurements using calibration factors derived from cross-calibration of standard sources containing known total activities of radium-226 with geometry identical to the counted samples and from the principles of radioactive decay. After approximately 24 hours, the exposed charcoal was transferred to a sealed plastic sample container (to prevent sample loss and/or further exposure during transport), identified and labeled, and transported to the Tellco laboratory in Grand Junction, Colorado for analysis. Tellco personnel maintained custody of the samples from collection through lab analysis. Upon completion of on-site activities, the field equipment was alpha and beta-gamma scanned by Energy Fuels Radiation Safety personnel for possible contamination resulting from fieldwork activities. All of the field equipment used was subsequently released for unrestricted use. 5. FIELD OPERATIONS 5.1 Equipment Preparation All charcoal was dried at 110°C before use in the field. Unused charcoal and recycled charcoal were treated the same. 180-gram aliquots of dried charcoal were weighed and placed in sample containers. Proper balance operation was verified daily by checking a standard weight. The balance readout agreed with the known standard weight to within± 0.1 percent. After acceptable balance check, empty containers were individually placed on the balance and the scale was re-zeroed with the container on the balance. Unexposed and dried charcoal was carefully added to the container until the readout registered 180 grams. The lid was immediately placed on the container and sealed with plastic tape. The balance was checked for readout drift between readings. Sealed containers with unexposed charcoal were placed individually in the shielded counting well, with the bottom of the container centered over the detector, and the background count rate was documented. Three five-minute background counts were conducted on ten percent of the containers, selected at random to represent the "batch". If the background counts were too high to achieve an acceptable lower limit of detection (LLD), the entire charcoal batch was labeled non-conforming and recycled through the heating/drying process. 5.2 Sample Locations, Identification, and Placement On October 9, 2019, 100 sampling locations were spread out throughout the Cell 2 covered region. The approximate sampling locations that were established for previous samplings of Cell 2 were used for · the placement of the canisters, although the actual sample identification numbers (IDs) are different. An individual ID was assigned to each sample point, using a sequential alphanumeric system indicating the charcoal batch and physical location within the region ( e.g., FO 1 ... F 100). This ID was written on an adhesive label and affixed to the top of the canister. The sample ID, date, and 2 time of placement were recorded on the radon flux measurements data sheets for the set of one hundred measurements. Prior to placing a canister at each sample location, the retaining ring, screen, and foam pad of each canister were removed to expose the charcoal support grid. A pre-measured charcoal charge was selected from a batch, opened and distributed evenly across the support grid. The canister was then reassembled and placed face down on the surface at each sampling location. Care was exercised not to push the device into the soil surface. The canister rim was "sealed" to the swJace using a berm of local borrow material. Five canisters (blanks) were similarly processed and these canisters were kept inside an airtight plastic bag during the 24-hour testing period. 5.3 Sample Retrieval On October 10, 2019 at the end of the 24-hour testing period, all canisters were retrieved, disassembled and each charcoal sample was individually poured through a funnel into a container. Identification numbers were transferred to the appropriate container, which was sealed and placed in a box for transpo1t. Retrieval date and time were recorded on the same data sheets as the sample placement information. The blank samples were similarly processed. All 100 of the charcoal samples from the Cell 2 covered region were successfully retrieved and containerized during the retrieval and unloading process. Upon completion of on-site activities, the field equipment was alpha and beta-gamma scanned by Energy Fuels Radiation Safety personnel and released for unrestricted use. 5.4 Environmental Conditions A rain gauge was placed at Cell 2 to monitor rainfall during sampling; additionally, Energy Fuels maintains an onsite rain gauge. In accordance with 40 CPR, Part 61, Appendix B, Method 115: • Measurements were not initiated within 24 hours of rainfall at the site. • No rainfall occurred during the 24-hour sampling period after the canisters had been deployed. • All canister seals remained intact during the 24-hour sampling period and none of the canisters were surrounded by water. 6. SAMPLE ANALYSIS 6.1 Apparatus Apparatus used for the analysis: • Single-or multi-channel pulse height analysis system, Ludlum Model 2200 with a Teledyne 3" x 3" sodium iodide, thallium-activated (Nal(Tl)) detector. 3 • Lead shielded counting well approximately 40 cm deep with 5-cm t~ick lead walls and a 7- cm thick base and 5 cm thick top. • National Institute of Standards and Technology (NIST) traceable aqueous solution radium- 226 absorbed onto 180 grams of activated charcoal. • Ohaus Port-0-Gram balance with 0.1-gram sensitivity. 6.2 Sample Inspection and Documentation Once in the laboratory, the integrity of each charcoal container was verified by visual inspection of the plastic container. Laboratory personnel checked for damaged or unsealed containers and also checked that the data sheet was complete. · All 100 of the sample containers and 5 blank containers inspected at the Tellco analytical laboratory were ultimately verified as valid with no damaged or unsealed containers observed. 6.3 Background and Sample Counting The gamma ray counting system was checked daily, including background and radiwn-226 source measurements prior · to and after each counting session. Based on calibration statistics, using two sources with known radium-226 content, background and source control limits were established for each Ludlum/Teledyne system with shielded counting well (see Appendix A). Gamma ray counting of exposed charcoal samples included the following steps: • The length of count time was determined by tbe activity of the sample being analyzed, according to a data quality objective of a minimum of 1,000 accrued counts for any given sample. • The sample container was centered on the Nal gamma detector and the shielded well door was closed. • The sample was counted over a determined count length and then the mid-sample count time, date, and gross counts were documented on the radon flux measurements data sheet and used in the calculations. • The above steps were repeated for each exposed charcoal sample. • Approximately 10 percent of the containers counted were selected for recow1ting. These containers were promptly recounted within a few days following the original count. 7. QUALITY CONTROL (QC) AND DATA VALIDATION Charcoal flux measurement QC samples included the following intra-laboratory analytical frequency objectives: • Blanks, 5 percent, and • Recounts, 10 percent 4 All sample data were subjected to validation protocols that included assessments of sensitivity, precision, accuracy, and completeness. As described below, all Method 115-required data quality objectives (EPA, 2019) were attained. 7.1 Sensitivity A total of five 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 approximately 5 percent of the field measurements. Analysis· of the five blank samples measured radon flux rates ranging from less than 0.03 to 0.09 pCi/m2-s, with an aritlunetic average of approximately 0.05 pCi/m2-s. The lower limit of detection (LLD) for the field blanks was approximately 0.04 pCi/m2-s. 7 .2 Precision Ten recount measurements, distributed throughout the sample set, were perfo1med by replicating analyses of individual field samples (see Appendix B). These recount measurements comprised approximately 10 percent of the total number of samples analyzed. The precision of recount measurements, expressed as relative percent difference (RPD), for sample result values that were above 1 pCi/m2-sec ranged from less than 0.1 percent to approximately 8.7 percent, with an average of approximately 4.5 percent. This complies with the precision objective of+/-10 percent. 7.3 Accuracy Accuracy of field measurements was assessed daily by counting two laboratory control samples with known Ra-226 content. Accuracy of these lab control sample measurements, expressed as percent bias, ranged from approximately -1.3 percent to +0.9 percent. The arithmetic average bias of the lab control sample measurements was approximately -0.1 percent (see Appendix A). This complies with the accuracy objective of+/-10 percent bias. 7.4 Completeness All 100 samples from the Cell 2 cover region were verified as valid, representing 100 percent completeness, which complies with the completeness objective of 85 percent. 8. CALCULATIONS Radon flux rates were calculated for charcoal collection samples using calibration factors derived from cross-calibration to 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. Individual field sample result values presented were not reduced by the results of the field blank analyses. 5 In practice, radon flux rates were calculated by a database computer program. The algorithms utilized by the data base program were ~s follows: Equation 8.1: pCi Rn-222/m2sec = [rs* A *b~.sCll/9l.7S)] where: N = net sample count rate, cpm under 220-662 keV peak Ts = sample duration, seconds b = instrument calibration factor, cpm per pCi; values used: 0.16895, forM-01/D-21 and 0.16975, for M-02/D-20 d = decay time, elapsed hours between sample mid-time and count mid-time A = area of the canister, m2 Equation 8.2: Gross Sample, cpm Background Sample, cpm ,--------+--------- SampleCount,t,min Background Count,t,min Error,2c, = 2X -'-------------------x Sample Concentration Equation 8.3: _ 2.71+(4.65){S~ LLD -[Ts* A *b*O.s<cll9 .1s1 where: 2.71 = constant 4.65 = confidence interval factor Net,cpm Sb = standard deviation of the background count rate Ts = sample duration, seconds b = instrument calibration factor, cpm per pCi; values used: 0.16895, forM-01/D-21 and 0.16975, for M-02/D-20 d = decay time, elapsed hours between sample mid-time and count mid-time A = area of the canister, m2 9.

(b) Using the data presented above, the calculated mean radon flux for Cell 2 is as follows: Cell 2 = 2.3 pCi/m2-s (2.3)(270,624) = 2.3 270,624 As shown above, the arithmetic mean of the radon flux rate measurements representing the second half of the year 2019 for Cell 2 at Energy Fuels' White Mesa milling facility is well below the U.S. Nuclear Regulatory Commission and EPA regulatory standard of 20 pCi/m2-s. No condition or unusual events were observed during the measurements that could significantly affect the results. Appendix C presents the summary of individual measurement results, including blank sample analysis. Sample locations are depicted on Figure 2, which is included in Appendix D.
