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 in 2014 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 was amended by the Division of Radiation Control ("DRC") on July 10, 2014. License Amendment 7 ("Amendment 7") dated July 10, 2014, among other things, modified and expanded the effluent monitoring programs implemented at the Mill. Amendment 7 required additional monitoring beyond what is regularly required by NRC Regulatory Guide 4.14. DRC requested the additional monitoring be documented in a revision to the Mill's Environmental Protection Manual ("EPM"). As required, EFRI submitted a revised EPM for DRC approval on September 8, 2014. A subsequent DRC Request for Information ("RFI") dated October 14, 2014 and e-mail correspondence dated October 20, 2014 added additional monitoring requirements beyond those specified in Amendment 7. EFRI incorporated the modifications resulting from the RFI and e-mail correspondence into an EPM revision submitted to DRC on November 18, 2014. The November 18, 2014 EPM was approved by DRC in a letter dated December 10, 2014. Specific changes to the individual monitoring programs resulting from Amendment 7, the RFI and the e-mail correspondence are discussed in the subsequent sections of this report. In a letter dated July 23, 2014, DRC 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 Cell2 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 DRC. As a result of the July 23, 2014 letter, Cell 2 radon flux monitoring data are reported herein. Additional details 1 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 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 (BVH-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) Radon flux of the Cell 2 cover as specified by the DRC in correspondence dated July 23, 2014; i) Groundwater (up and down gradient) of the Mill facility; and1 j) Seeps and springs in the vicinity of the Mill. 1 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 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 Amendment 7, 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 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, Amendment 7 expanded the air particulate monitoring program. Amendment 7 included the following expansion of the air particulate monitoring program: • Addition of two air monitoring stations (BHV -7 and BHV -8); • 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 approximately 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. While air sampling was discontinued at this location, gamma 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, BHV-7 and BHV-8. As noted above, BHV-3 was removed from the active air monitoring program in November 1995. BHV-7 and BHV-8 are discussed in detail below. 3 Pursuant to Amendment 7, the associated RFI and e-mail correspondence, EFRI submitted a revised EPM which was approved by DRC letter dated December 10, 2014. Amendment 7 required the implementation of the revised monitoring programs within 90 days of approval of the EPM or March 10, 2015. As a good faith effort, EFRI began procurement of the equipment for the BHV -7 and BHV -8 monitoring stations and began analyzing Th-232 at the existing five stations immediately upon receipt of Amendment 7. Data for Th-232 are presented for the reporting period for the existing five sampling locations (BHV-1, BHV-2, BHV-4, BHV-5 and BHV-6). Installation of the platforms and equipment at BHV -7 and BHV -8 was completed in the fourth quarter prior to the approval for the EPM. Prior to the EPM approval, EFRI tested solar cells as a means of powering BHV -7 and BHV -8. The solar cells were unsuccessful and line power was installed. Due to solar cell power issues, the fourth quarter air particulate data from BHV -7 and BHV -8 is incomplete. The limited amount of usable data for BHV -7 and BHV -8 are included in Attachment B as appropriate. It is important to note that the data collection from BHV-7 and BHV-8 is not required until March 10,2015. 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 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 and is not shown on the Figure. 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. As noted above, data for BHV -7 and BHV -8 are included when available. Graphical presentation of radionuclide and particulate data for BHV -7 and BHV-8 is or will be included when two or more data points are available. The sampling periods beginning December 15, 2014 has been omitted from particulate loading on the graph for BHV -1 in Attachment D. The timer on the airborne particulate monitoring station at BHV -1 malfunctioned, and the data are considered invalid due to 4 the inability to measure the time sampled. The timer was replaced prior to the next sampling period and all other measurements are valid. For graphical illu trati n purp ·e· va lue reported at zero, values reported at less than the prescribed detection limit (< t x 1.0"16 uCi/ml), and missing values were plotted as 1 x 10-16 uCi/ml concentrations. Where otb. ··r "less than" values were indicated (i.e., where detection limits for the data varied from 1 X w-'6 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. It is noteworthy 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 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 5 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/m3f 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 nine of the several thousand total gross radionuclide determinations to date exceeded the Mill's self-imposed 25% ALARA goal). 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 MILDOS code for estimating environmental radiation doses for uranium recovery operations. R313-15-302(2)(a) contemplates demonstrating compliance either through modeling or measurement. 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 6 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. Fourth quarter 2014 data for BHV-7 and BHV-8 are included but graphical presentation of Radon-222 data for BHV-7 and BHV-8 will be included when two or more data points are available. As stated in Section 1.1 above, Amendment 7 expanded the Mill's effluent monitoring programs in 2014. Amendment 7 included expanding the monitoring programs to require the collection of Radon-222 data at all of the BHV stations. For BHV stations 1 through 6, EFRI previously calculated Effluent Concentration Limits ("ECLs") using methodology specified in the Semi-annual Effluent Report for July 2008 through December 2008, submitted to DRC on February 27, 2009. ECLs for BHV-7 and BHV-8 have been calculated using the same methodology. The ECLs for all of the BHV stations are included on the data table included in Attachment J. 3.0 EXTERNAL RADIATION (DIRECT GAMMA) Gamma exposure rate estimates were measured for the reporting 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, Amendment 7 expanded the effluent monitoring programs at the Mill. Amendment 7 included 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). Gamma was monitored at the 2 new air monitoring stations in both the third and fourth quarter of 2014. The third quarter OSLs from BHV-7 and BHV-8 were only deployed for a portion of the third quarter because they were placed upon completion of construction of the monitoring station platforms. The OSLs could not be placed prior to the siting and completion of the monitoring stations. 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 6 in the Tables Tab of this report. 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-1, BHV-2, BHV-4, BHV-5, BHV-6, BHV-7, and BHV-8 are within regulatory limits. 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. 7 4.0 VEGETATION SAMPLES Vegetation samples are collected at three locations around the Mill property. The sampling locations are: 1) northeast, 2) northwest and 3) southwest of the Mill facility. 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. During the 2014 grazing season, samples were collected on April 16, 2014, June 10, 2014, and November 25, 2014. The data from the April and June sampling were included in the January through June 2014 Semi-Annual Effluent Report ("SAER") which was submitted to the DRC on August 29, 2014. Data from the November sampling event are included in this report. 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. The November 2014 samples were collected prior to the approval of the EPM and U-Nat and Th-232 were not added to the suite of analyses for the November 2014 samples. Implementation of the expanded analyte list will begin with the first samples collected in 2015. 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 2014 data results are within the variation of previous sampling episodes. 5.0 STACK SAMPLING Under Section 5.0 of Tab 1.4 of the Mill's Environmental Protection Manual, Revision: EFR-4, 11/14 (the "Environmental Protection Manual") as modified in response to DRC e-mail correspondence dated October 20, 2014 , gas stack samples are collected at the Mill in accordance with the schedule shown below: 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. 8 The analytical results of stack sampling conducted for the third quarter of 2014 were conducted prior to the DRC e-mail correspondence which expanded the stack sampling program as shown above. The third quarter sampling was threfore compliant with the previous requirement to sample U-Nat only during the first and third quarter sampling events. The third quarter data, as well as data for the first and second quarters of 2014, are provided in Table 8 in the Tables Tab of this report. No drying or packaging were conducted during the fourth quarter of 2014 and therefore, no sampling was completed. The actual analytical results reported by the laboratory for the third quarter of 2014 are provided in Attachment G to this report. The south yellowcake dryer and yellowcake baghouse operated during the third quarter of 2014. 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. None of the facilities requiring stack sampling operated during the fourth quarter 2014. It is also important to note that stack effluent concentrations are not comparable to environmental air sampling station ECL's 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. 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 surface water was sampled in the third quarter of 2014. The Mill's Environmental Protection Manual 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 during the third quarter. A fourth quarter sample was not collected from Cottonwood Creek because no water was present during the quarter. Three visits were made to Cottonwood Creek during the fourth quarter. Documentation of the visits and photographs of the conditions are included in Attachment H. The field data sheets for the surface water sampling events, along with graphs showing current and historic results are included as Attachment H. The results of this sampling indicate that surface water concentrations remain low and within the range of typical background levels. 9 7.0 SOIL SAMPLING The previous revision of the Mill's EPM required that surface soils be sampled at the Mill's air monitoring stations (BHV-1, BHV-2, BHV-3, BHV-4, BHV-5 and BHV-6) once per year during August or as soon as possible thereafter, but no later than September 30 of each year. In accordance with the Mill's EPM, surface soils were collected during the third quarter of 2014. As previously noted in Section 1.1 of this report, Amendment 7 and the associated RFI expanded the Mill's soil sampling program. In addition to continued soil sampling at the existing air monitoring locations (BHV -1 through BHV -6), soil samples will be collected at the two new air monitoring stations (BHV -7 and BHV -8) and at additional locations along the boundary of the Mill. Further, the RFI expended the analytical suite for the soil samples to include Th-232 and Pb-210. Pursuant to the approved EPM, 44locations will be sampled on the boundary of the Mill. The 2014 soil samples were collected in August 2014 as required by the EPM that was approved at the time. As previously stated, the revised EPM resulting from Amendment 7 was approved on December 10, 2014, well after the annual soil sampling window specified in the approved EPM. Soil samples are collected annually. The expanded soil sampling at BHV-7 and BHV-8 and the 44 boundary locations with the expanded analyte list will be implemented beginning with the annual sampling event of 2015. In accordance with the Mill's Environmental Protection Manual, surface soils were collected in August 2014. The soil samples were analyzed, on a dry basis, for Ra-226 and U-nat. The results of these samplings indicate that soil activity levels at the air monitoring stations remain low and within the range of typical background levels. A graphical presentation of the historical results for soils at the air monitoring stations, together with analytical sample results for the August 2014 sampling are provided 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 period of July through December 2014. This information is retained at the Mill site for agency review. 9.0 CELL 2 RADON FLUX The radon flux from Cell2 during 2012 was higher than the 20 pCi/(m2 -sec) set out in 40 CFR 61.252(a). Although Cell 2 is no longer in operation, consistent with 40 CFR 61.254b, EFRI chose to perform monthly radon flux monitoring beginning the month immediately following submittal of the report for the year in non-compliance. The result of the 2013 radon-222 flux monitoring for Cell 2 was 20.4 pCi/(m2 -sec) (averaged over 9 monthly sampling events), which slightly exceeds the 20 pCi/(m2 -sec). Monthly sampling for Cell 2 was conducted from April of 2013 through June of 2014. A summary 10 of the events that gave rise to EFRI' s decision to monitor radon flux at Cell 2 monthly consistent with 40 CFR 61.254(b) is set out in Section 4.0 of the June 2014 Monthly Report submitted to DRC July 29, 2014. EFRI submitted monthly reports from May 2013 through July 2014 summarizing the April 2013 through June 2014 monthly sampling at Cell 2. A summary of the monthly Cell 2 radon flux measurements, as well as the date the EFRI monthly reports were submitted to the Utah Division of Air Quality ("UDAQ"), is included in Attachment K of this report. EFRI began interim mitigation of radon flux from Cell 2 in 2013, as a result of the 2012 monitoring results, by applying one foot of additional soil cover to areas of Cell 2 with elevated radon. Details of the interim radon mitigation cover construction activities and interim corrective actions are described in the monthly reports. EFRI completed the first phase of the interim cover installation on 12 test areas in September of 2013. The effectiveness of the additional compacted cover at the 12 test areas was evaluated over several months. The additional cover on the 12 test areas was successful in achieving the desired reduction to 20 pCi/(m2-sec) or lower. As a result, EFRI applied additional random fill at 90% compaction to other areas of Cell 2 to further reduce the radon flux measurements. Based on the monthly results, EFRI submitted a Request to Cease Monthly Sampling on May 30, 2014 with the April 2014 Monthly Report. On July 23, 2014 EFRI received approval from DRC to cease monthly sampling. The July 23, 2014 letter required that Cell 2 radon flux measurements continue as detailed below. The July 23, 2014 letter, DRC 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 DRC 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 DRC will require the licensee to continue to measure the radon flux in accordance with 40 CFR 61, Appendix B, Method 115, "Monitoring for Radon-222 Emissions" (2013). 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." EFRI sampled Cell 2 radon flux in July 2014. The measurement was slightly above the 20 pCi/(m2-sec) standard at 20.4 pCi/(m2-sec). EFRI immediately began radon 11 mitigation cover construction activities and contacted DRC. DRC directed EFRI to complete radon mitigation cover construction activities and sample by the end of the calendar year. EFRI completed the radon mitigation cover construction activities and sampled in September 2014. The September 2014 result was below the standard at 15.8 pCi/(m2-sec). DRC directed EFRI to average the July and September measurements. The average of the July and September measurements is 18.1 which is below the 20 pCi/(m2 -sec) standard. The 2012 through 2014 Cell 2 radon flux data are summarized in Attachment K. At the request of DRC, the 2014 data will be reported to UDAQ in a final report submitted on or before March 30, 2015. 12 10.0 SIGNATURE This report was prepared by Energy Fuels Resources (USA) Inc. on February 26, 2015.

The data presented here is from that additional reporting request. The report has been revised and replaces any previously issued report in its entirety. ORIGINAL SAMPLE SUBMITIAL(S) All original sample submittals have been returned with the data package. SAMPLE TEMPERATURE COMPLIANCE: 4"C (±2"C) 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 Ell reflects the results for seven individual Aroclors. When the results for all seven are NO (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: 02/08/15 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 Ell reflects the results for seven individual Aroclors. When the results for all seven are NO (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 IV INTRODUCTION Test Purpose This test project was conducted to determine the total radionuclide emissions from the South Yell ow Cake Scrubber and the Yell ow Cake Dryer Baghouse exhausts in terms of Curies per dry standard cubic foot (Ci/dscf). These tests were for U-Nat only. Test Location and Type of Process Energy Fuels Resources is located about 5 miles south of Blanding, Utah. Uranium ore is processed into yellow cake, which is shipped to other facilities for additional processing. There are two yellow cake dryers with individual scrubbers. Both dryer enclosures discharge into the Yell ow Cake Dryer Baghouse. The packaging enclosure also discharges into the Yell ow Cake Dryer Baghouse. The South Yell ow Cake (SYC) dryer was the only operating dryer at the time of the test. The North Yell ow Cake dryer is currently not operational. The Grizzly Baghouse serves as the main dust control device for the raw ore unloading and conveying to the processing building. Stack schematics are shown as Figures 1 and 2 in Appendix D. Test Dates The first test run on the SYC Scrubber was completed July 29, 2014 and the second run on July 30,2014. One run was completed on the Yellow Cake Dryer Baghouse July 29, and the second run was completed July 30, 2014. Pollutants Tested and Methods Applied The tests were a determination ofradionuclide emissions in accordance with EPA Method 5/114. Test run filters and front wash residues were sent to Test America located in Richland, Washington for radionuclide analysis.

Uncertainty Estimation TestAmerica Richland has adopted the internationally accepted approach to estimating uncertainties described in "NIST Technical Note 1297, 1994 Edition". The approach, "Law of Propagation of Errors", involves the identification of all variables in an analytical method which are used to derive a result. These variables are related to the analytical result (R) by some functional relationship, R = constants * f(x,y,z, ... ). The components (x,y,z) are evaluated to determine their contribution to the overall method uncertainty. The individual component uncertainties (u;) are then combined using a statistical model that provides the most probable overall uncertainty value. All component uncertainties are categorized as type A, evaluated by statistical methods, or type B, evaluated by other means. Uncertainties not included in the components, such as sample homogeneity, are combined with the component uncertainty as the square root of the sum-of-the-squares of the individual uncertainties. The uncertainty associated with the derived result is the combined uncertainty (uc) multiplied by the coverage factor (1,2, or 3). When three or more sample replicates are used to derive the analytical result, the type A uncertainty is the standard deviation of the mean value (S/? n), where S is the standard deviation of the derived results. The type B uncertainties are all other random or non-random components that are not included in the standard deviation. The derivation of the general "Law of Propagation of Errors" equations and specific example are available on request. 0.

Often the Action Level is related to the Decision Limit. The QC preparation batch number that relates laboratory samples to QC samples that were prepared and analyzed together. Defined by the equation (Result/Expected)-! as defined by ANSI Nl3.30. Chain of Custody Number assigned by the Client or TestAmerica. Poisson counting statistics of the gross sample count and background. The uncertainty is absolute and in the same units as the result. For Liquid Scintillation Counting (LSC) the batch blank count is the background. All known uncertainties associated with the preparation and analysis of the sample are propagated to give a measure of the uncertainty associated with the result, Uc the combined uncertainty. The uncertainty is absolute and in the same units as the result. The coverage factor defines the width of the confidence interval, 1, 2 or 3 standard deviations. Contractual Required Detection Limit as defined in the Client's Statement Of Work or TestAmerica "default" nominal detection limit. Often referred to the reporting level (RL) Decision Level based on instrument background or blank, adjusted by the Efficiency, Chemical Yield, and Volume associated with the sample. The Type I error probability is approximately 5%. Lc=(l .645 * Sqrt(2*(BkgrndCnt/BkgmdCntMin)/SCntMin)) * (ConvFct/(Eff*Yld*Abn*Vol) * IngrFct). For LSC methods the batch blank is used as a measure of the background variability. Lc cannot be calculated when the background count is zero. The number assigned by the LIMS software to track samples received on the same day for a given client. The sample number is a sequential number assigned to each sample in the Lot. Detection Level based on instrument background or blank, adjusted by the Efficiency, Chemical Yield, and Volume with a Type I and II error probability of approximately 5%. MDC = ( 4.65 * Sqrt((BkgrndCnt/BkgmdCntMin)/SCntMin) + 2.71/SCntMin) * (ConvFct/(Eff* Yld * Abn *Vol)* IngrFct). For LSC methods the batch blank is used as a measure of the background variability. The instrument identifier associated with the analysis of the sample aliquot. The U-234 result divided by the U-238 result. The U-234/U-238 ratio for natural uranium in NIST SRM 4321 C is 1.038. Ratio of the Result to the MDC. A value greater than 1 may indicate activity above background at a high level of confidence. Caution should be used when applying this factor and it should be used in concert with the qualifiers associated with the result. Ratio of the Result to the Total Uncertainty. If the uncertainty has a coverage factor of2 a value greater than I may indicate activity above background at approximately the 95% level of confidence assuming a two-sided confidence interval. Caution should be used when applying this factor and it should be used in concert with the qualifiers associated with the result. Sample Identifier used by the report system. The number is based upon the first five digits of the Work Order Number. The equation Replicate Error Ratio= (S-D)/[sqrt(TPUs2 + TPUd2)] as defined by ICPT BOA where S is the original sample result, Dis the result of the duplicate, TPUs is the total uncertainty of the original sample and TPUd is the total uncertainty of the duplicate sample. Sample Delivery Group Number assigned by the Client or assigned by TestAmerica upon sample receipt. The sum of the reported alpha spec results for tests derived from the same sample excluding duplicate result where the results are in the same units. The LIMS software assign test specific identifier. The recovery of the tracer added to the sample such as Pu-242 used to trace a Pu-239/40 method. 5 of 15 Sample Results Summary Date: 27-Aug-14 TestAmerica Inc Ordered by Method, Batch No., Client Sample I D.

SAMPLE TEMPERATURE COMPLIANCE: 4"C (±2"C) 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 Ell 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) 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 Ell reflects the results for seven individual Aroclors. When the results for all seven are NO (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: 4CC (±2CC) 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 Ell reflects the results for seven individual Aroclors. When the results for all seven are NO (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.

INTRODUCTION During July 14-15,2014 Tellco Environmental, LLC (Tellco) of Grand Junction, Colorado, provided support to Energy Fuels Resources (USA) Inc. (Energy Fuels) to conduct radon flux measurements at its White Mesa Mill site regarding the required National Emission Standards for Hazardous Air Pollutants (NESHAPs) Radon Flux Measurements. These measurements are required of Energy Fuels to show compliance with Federal Regulations (further discussed in Section 3 below). The standard is not an average per facility, but is an average per radon source. The standard allows mill owners or operators the option of either making a single set of measurements to represent the year or making multiple measurements over a one year period (e.g., weekly, monthly, or quarterly intervals). Energy Fuels is presently performing radon flux measurements on a monthly basis at Cell 2. Prior to 2012, Energy Fuels had been making a single set of measurements to represent the radon flux each year; however, as the radon flux levels began exceeding the regulatory standard of 20 picoCuries per square meter per second (pCi/m2-s) in 2012, Energy Fuels responded by opting to make the radon flux measurements on a more frequent basis. Also, in response to the increase in the radon flux rates, Energy Fuels has placed approximately 19,432 cubic meters of additional material, varying in depth from approximately 31-61 centimeters, throughout an area of approximately 50,130 square meters (m2). In March 2014, Energy Fuels suspended the placement of additional cover materials at Cell 2 because the average flux rate had been below the regulatory standard for several months. 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. This report presents the radon flux measurements results only for Cell2 for July 2014; no radon flux measurements were performed for Cell3 during July 2014. 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. Processing effluents from the operation are deposited in lined cells, which vary in depth. Celli, Cell4A, and Cell4B did not require radon flux sampling, as explained in Section 3 below. Cell 2, which has a total area of approximately 270,624 m2, has been filled and covered with interim cover. This cell is comprised of one region, an interim soil cover of varying thickness, which requires NESHAPs radon flux monitoring. There were no apparent exposed tailings within Cell 2 during the July 2014 sampling. Cell 3, which has a total area of approximately 288,858 m2, is nearly filled with tailings sand and is undergoing pre-closure activities. This cell is comprised of two source regions that require NESHAPs 1 radon monitoring: a soil cover region of varying thickness and an exposed tailings "beaches" region. The remaining area is covered by standing liquid in lower elevation areas. 3. REGULATORY REQUIREMENTS FOR THE SITE Radon emissions from the uranium mill tailings at this site are regulated by the State of Utah's Division of Radiation Control and administered by the Utah Division of Air Quality under generally applicable standards set by the U.S. Environmental Protection Agency (EPA) for Operating Mills. Applicable regulations are specified in 40 CFR Part 61, Subpart W, National Emission Standards for Radon Emissions from Operating Mill Tailings, with technical procedures in Appendix B. At present, there are no Subpart T uranium mill tailings at this site. These regulations are a subset of the NESHAPs. According to subsection 61.252 Standard, (a) radon-222 emissions to ambient air from an existing uranium mill tailings pile shall not exceed an average of 20 pCi/m2 -s for each pile (or cell). 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." Cell 1 is completely covered with standing liquid and therefore no radon flux measurements are required on Celli. The repaired Cell 4A, and newly constructed Cell 4B, were both constructed after December 15, 1989 and each was constructed with less than 40 acres surface area. Cell 4A and 4B comply with the requirements of 40 CFR 61.252(b ), therefore no radon flux measurements are required on either Cell4A or 4B . 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, 2013). 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 lh inch thick layer of foam and secured with a retaining ring under llh inches of foam (see Figure 1, page 10). 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 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 radon loss and/or further exposure during transport), identified and labeled, and transported to the Tellco laboratory in Grand Junction, Colorado for 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. Tellco personnel maintained custody of the samples from collection through analysis. 2 5. FIELD OPERATIONS 5.1 Equipment Preparation All charcoal was dried at 11 0°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 July 14, 2014, 100 sampling locations were spread out throughout the Cell 2 covered region. The same 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., K01 ... K100). This ID was written on an adhesive label and affixed to the top of the canister. The sample ID, date, and 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 surface 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 July 15, 2014 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 3 transport. Retrieval date and time were recorded on the same data sheets as the sample placement information. The blank samples were similarly processed. All 100 charcoal samples from Cell 2 covered region were successfully retrieved and containerized during the retrieval and unloading process. Tellco personnel maintained custody of the samples from collection through lab analysis. 5.4 Environmental Conditions A rain gauge and thermometer were placed at Cell 2 to monitor rainfall and air temperatures during sampling; additionally, Energy Fuels maintains an onsite rain gauge. In accordance with 40 CFR, Part 61, Appendix B, Method 115: • Canisters were not placed within 24 hours of rainfall at the site. • After the completion of the placement of the canisters, the rain gauge measured approximately 0.08 inches of rainfall that occurred overnight while the canisters were emplaced. • The criteria regarding minimum ambient air temperature and frozen ground do not apply when performing sampling on a monthly basis; however, the minimum air temperature during the sampling period was 63 degrees F, and the ground was not frozen at any of the sample locations. 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. • Lead shielded counting well approximately 40 em deep with 5-cm thick lead walls and a 7- cm thick base and 5 em thick top. • National Institute of Standards and Technology (NIST) traceable aqueous solution radium- 226 absorbed onto 180 grams of activated charcoal. • Ohaus Model C501 balance with 0.1-gram sensitivity. 4 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 verified that the data sheet was complete. All of the 100 sample containers and 5 blank containers received and inspected at the Tellco analytical laboratory were ultimately verified as valid and no damaged or unsealed containers were observed. 6.3 Background and Sample Counting The gamma ray counting system was checked daily, including background and radium-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 the 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 recounting. These containers were recounted on the next day 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, 1 0 percent All sample data were subjected to validation protocols that included assessments of sensitivity, precision, accuracy, and completeness. All method-required data quality objectives (EPA, 2013) were attained. 5 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 approximately 0.00 to 0.01 pCi/m2-s, with an average of approximately 0.01 pCilm2-s. The lower limit of detection (LLD) was approximately 0.03 pCi/m2-s. 7.2 Precision Ten recount measurements, distributed throughout the sample set, were performed 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 all recount measurements, expressed as relative percent difference (RPD), ranged from less than 0.1 percent to 6.9 percent with an overall average precision of approximately 2.5 percent RPD. 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 -3.5 percent to +1.0 percent. The arithmetic average bias of the lab control sample measurements was approximately -1.6 percent (see Appendix A). 7.4 CompJeteness All 100 of the samples from the Cell 2 cover regiOn were verified, representing 100 percent completeness. 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. In practice, radon flux rates were calculated by a database computer program. The algorithms utilized by the data base program were as follows: Equation 8.1: pCi Rn-222/m2sec = [Ts* A *b*~.s<d/91.7s)] 6 where: N =net sample count rate, cpm under 220-662 keY peak Ts = sample duration, seconds b = instrument calibration factor, cpm per pCi; values used: 0.1698, forM-01/D-21 and 0.1703, 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,2a = 2x -'-------------------X Sample Concentration Net,cpm 1 quation 8 : where: 2.71 =constant 4.65 =confidence interval factor sb = standard deviation of the background count rate Ts = sample duration, seconds b =instrument calibration factor, cpm per pCi; values used: 0.1698, for M-01/D-21 and 0.1703, 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.

Any condition or unusual event that occurred during the measurements that could significantly affect the results should be reported." 9.2 Site Results Site Specific Sample Results (reference Appendix C) (a) The mean radon flux for the Cell2 region at the site is as follows: Cell 2 -Cover Region -20.4 pCi/m2 -s (based on 270,624 m2 area) Note: Reference Appendix C of this report for the entire summary of individual measurement results. (b) Using the data presented above, the calculated mean radon flux for Cell2 is as follows: Cell2 = 20.4 pCi/m2-s (20.4)(270,624) = 20.4 270,624 As shown above, the arithmetic mean radon flux of the samples for Cell 2 at Energy Fuels' White Mesa milling facility slightly exceeds the U.S. Nuclear Regulatory Commission and EPA standard of20 pCi/m2-s. The July 2014 sampling results for Cell2 are higher than the June 2014 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. The map was produced by Tellco. 8 References U. S.

INTRODUCTION During September 13-14, 2014 Tellco Environmental, LLC (Tellco) of Grand Junction, Colorado, provided support to Energy Fuels Resources (USA) Inc. (Energy Fuels) to conduct radon flux measurements at its White Mesa Mill site regarding the required National Emission Standards for Hazardous Air Pollutants (NESHAPs) Radon Flux Measurements. These measurements are required of Energy Fuels to show compliance with Federal Regulations (further discussed in Section 3 below). The standard is not an average per facility, but is an average per radon source. The standard allows mill owners or operators the option of either making a single set of measurements to represent the year or making multiple measurements over a one year period (e.g., weekly, monthly, or quarterly intervals). Energy Fuels is presently performing radon flux measurements on a monthly basis at Cell 2. Prior to 2012, Energy Fuels had been making a single set of measurements to represent the radon flux each year; however, as the radon flux levels began exceeding the regulatory standard of 20 picoCuries per square meter per second (pCi/m2 -s) in 2012, Energy Fuels responded by opting to make the radon flux measurements on a more frequent basis. Energy Fuels began placing additional material at selected areas on Cell2 during June 2013. In March 2014, the placement of additional cover materials was suspended because the average flux rate had been below the regulatory standard for several months. However, the average flux rate again exceeded the regulatory standard in July 2014 and Energy Fuels resumed the placement of additional cover materials at Cell2 during August 2014. 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. This report presents the radon flux measurements results only for Cell 2 for September 2014; the results of the radon flux measurements performed for Cell3 during September 2014 are presented in a separate 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. Processing effluents from the operation are deposited in lined cells, which vary in depth. Cell1, Cell4A, and Cell4B did not require radon flux sampling, as explained in Section 3 below. Cell 2, which has a total area of approximately 270,624 m2, has been filled and covered with interim cover. This cell is comprised of one region, an interim soil cover of varying thickness, which requires NESHAPs radon flux monitoring. There were no apparent exposed tailings within Cell 2 during the September 2014 sampling. 1 Cell 3, which has a total area of approximately 288,858 m2, is nearly filled with tailings sand and is undergoing pre-closure activities. This cell is comprised of two source regions that require NESHAPs radon monitoring: a soil cover region of varying thickness and an exposed tailings "beaches" region. The remaining area of Cell 3 is covered by standing liquid in lower elevation areas. 3. REGULATORY REQUIREMENTS FOR THE SITE Radon emissions from the uranium mill tailings at this site are regulated by the State of Utah's Division of Radiation Control and administered by the Utah Division of Air Quality under generally applicable standards set by the U.S. Environmental Protection Agency (EPA) for Operating Mills. Applicable regulations are specified in 40 CFR Part 61, Subpart W, National Emission Standards for Radon Emissions from Operating Mill Tailings, with technical procedures in Appendix B. At present, there are no Subpart T uranium mill tailings at this site. These regulations are a subset of the NESHAPs. According to subsection 61.252 Standard, (a) radon-222 emissions to ambient air from an existing uranium mill tailings pile shall not exceed an average of 20 pCi/m2-s for each pile (or cell). 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." Cell 1 is completely covered with standing liquid and therefore no radon flux measurements are required on Celli. The repaired Cell 4A, and newly constructed Cell 4B, were both constructed after December 15, 1989 and each was constructed with less than 40 acres surface area. Cell 4A and 4B comply with the requirements of 40 CFR 61.252(b ), therefore no radon flux measurements are required on either Cell 4A or 4B. 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, 2014). 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 1 0-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 'li inch thick layer of foam and secured with a retaining ring under 1 'li inches of foam (see Figure 1, page 10). 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 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 radon loss and/or further exposure during transport), identified and labeled, and transported to the Tellco laboratory in Grand Junction, Colorado for 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 2 equipment used was subsequently released for unrestricted use. Tellco personnel maintained custody of the samples from collection through analysis. 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 September 13, 2014, 100 sampling locations were spread out throughout the Cell 2 covered region. The same 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., POl.. .PlOO). This ID was written on an adhesive label and affixed to the top of the canister. The sample ID, date, and 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 surface 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. 3 5.3 Sample Retrieval On September 14, 2014 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 transport. Retrieval date and time were recorded on the same data sheets as the sample placement information. The blank samples were similarly processed. All 100 charcoal samples from Cell 2 covered region were successfully retrieved and containerized during the retrieval and unloading process. Tellco personnel maintained custody of the samples from collection through lab analysis. 5.4 Environmental Conditions A rain gauge and thermometer were placed at Cell 2 to monitor rainfall and air temperatures during sampling; additionally, Energy Fuels maintains an onsite rain gauge. In accordance with 40 CFR, Part 61, Appendix B, Method 115: • Measurements were not initiated within 24 hours of rainfall at the site. • There was no rainfall during the 24-hour sampling period at Cell 2. • None of the canister seals were affected during the 24-hour sampling period. • The criteria regarding minimum ambient air temperature and frozen ground do not apply when performing sampling on a monthly basis; however, the minimum air temperature during the 24-hour sampling period was 53 degrees F, and the ground was not frozen. 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 (Nai(Tl)) detector. • Lead shielded counting well approximately 40 em deep with 5-cm thick lead walls and a 7- cm thick base and 5 em thick top. • National Institute of Standards and Technology (NIST) traceable aqueous solution radium- 226 absorbed onto 180 grams of activated charcoal. • Ohaus Model C501 balance with 0.1-gram sensitivity. 4 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 verified that the data sheet was complete. All of the 100 sample containers and 5 blank containers received and inspected at the Tellco analytical laboratory were ultimately verified as valid and no damaged or unsealed containers were observed. 6.3 Background and Sample Counting The gamma ray counting system was checked daily, including background and radium-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 the 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 1 0 percent of the containers counted were selected for recounting. These containers were recounted on the next day 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 All sample data were subjected to validation protocols that included assessments of sensitivity, precision, accuracy, and completeness. All method-required data quality objectives (EPA, 2014) were attained. 5 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 approximately 0.01 to 0.03 pCi/m2-s, with an average of approximately 0.02 pCilm2-s. The lower limit of detection (LLD) was approximately 0.03 pCi/m2-s. 7.2 Precision Ten recount measurements, distributed throughout the sample set, were performed 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 all recount measurements, expressed as relative percent difference (RPD), ranged from less than 0.1 percent to 3. 7 percent with an overall average precision of approximately 1.3 percent RPD. 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 -0.9 percent to + 1.3 percent. The arithmetic average bias of the lab control sample measurements was approximately +0.2 percent (see Appendix A). 7.4 Completeness All 100 of the samples from the Cell 2 cover regiOn were verified, representing 100 percent completeness. 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. In practice, radon flux rates were calculated by a database computer program. The algorithms utilized by the data base program were as follows: Equation 8.1: pCi Rn-222/m2sec = [Ts* A *b*~.s<dl9us)] 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: 6 0.1698, for M-01 /D-21 and 0.1703, 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 Sampl e , cpm Backg round Sample , cpm , ____ ....;;_ ___ + -- SampleCount,t ,min Bac kground Count,t,min Er ror,2CT = 2 X...!------------=---------x Sample Concentration Equation 8.3: - 2.71 +{4.65)( ,,) LLD-[H:"A'~'b~'O.S'wl':7s)] 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: 0.1698, forM-01/D-21 and 0.1703, 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. RESULTS 9.1 Mean Radon Flux 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 mean radon flux for each region of the pile shall be calculated by summing all individual flux measurements for the region and dividing by the total number of flux measurements for the region. (b) The mean radon flux for the total uranium mill tailings pile shall be calculated as follows: At Where: ls =Mean flux for the total pile (pCi/m2-s) Ji =Mean flux measured in region i (pCilm2-s) Ai =Area of region i (m2) At =Total area of the pile (m2)" 40 CFR 61, Subpart W, Appendix B, Method 115, Subsection 2.1.8, Reporting states "The results of individual flux measurements, the approximate locations on the pile, and the mean radon flux for each 7 region and the mean radon flux for the total stack [pile] shall be included in the emission test report. Any condition or unusual event that occurred during the measurements that could significantly affect the results should be reported." 9.2 Site Results Site Specific Sample Results (reference Appendix C) (a) The mean radon flux for the Cell2 region at the site is as follows: Cell 2 -Cover Region == 15.8 pCi/m2-s (based on 270,624 m2 area) Note: Reference Appendix C of this report for the entire summary of individual measurement results. (b) Using the data presented above, the calculated mean radon flux for Cell2 is as follows: Cell2 == 15.8 pCi/m2-s (15.8)(270,624) 15.8 270,624 As shown above, the arithmetic mean radon flux of the samples for Cell 2 at Energy Fuels' White Mesa milling facility slightly exceeds the U.S. Nuclear Regulatory Commission and EPA standard of20 pCi/m2-s. The September 2014 sampling results for Cell2 are lower than the July 2014 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. The map was produced by Tellco. 8 References U. S.
