WHITE MESA URANIUM MILL
SEMI-ANNUAL EFFLUENT REPORT, JANUARY THROUGH JUNE 2023
1.0 INTRODUCTION
The White Mesa Mill (the "Mill") has established monitoring programs to evaluate compliance
with effluent limitations and to assess the potential for release of radioactive material into the
local environment. 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. UTl 900479 (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. I, 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, the Division of Waste Management and Radiation Control
("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 approximately 1.2 miles north of
the Mill, but approximately 0.4 miles closer to the Mill than the nearest resident);
1
• 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 at 52 locations 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; and1
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 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

Ground Water Discharge Permit No. UGW370004, and are not included with this report.
2
information in the southerly direction between the Mill and the White Mesa Ute Community.
In 2014 the air particulate 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.
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
3
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.
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.
4
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 ECLs 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).
2.5 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.

Inc. prepared by Dames & Moore, January 30, 1978, Section 2.9 .1.1
5
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. The Mill's effluent
monitoring programs were expanded in 2014 and 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 found 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.
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). In 2014 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 report. In addition,
measurement data obtained at these locations are graphically presented in Attachment E to this
report.
6
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 and are
consistent with historical data. 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.
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 will be collected during the
July through December reporting period. In 2014 the vegetation sampling program was
expanded through the addition of Th-232 and U-Nat.
During the January through June reporting period, samples were collected on April 25, 2023, and
June 7, 2023. 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 these
sampling periods, are included as Attachment F of this report. The 2023 data results are within
the variation of previous sampling episodes and are comparable to historic results.
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 STACK SAMPLING
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:

and Th-228. and Th-228. and Th-228. and Th-228. and Th-228.
No stack sampling was conducted in the reporting period because none of the stacks were
operated during the reporting period. The uranium dryers (south yellowcake dryer and
yellowcake baghouse) last operated fourth quarter 2022, as previously reported. The north
yellowcake dryer has not been in operation since the third quarter 2012 and therefore, has not
been sampled since was last in operation.
The vanadium dryer and vanadium baghouse did not operate during the reporting period. The
vanadium dryers last operated first quarter 2020.
The analytical results of stack sampling conducted in the reporting period, as well as for the
previous two quarters, are provided in Table 8 of the Tables Tab in this report. The analytical
results reported by the laboratory for the reporting period 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.
When analytical data are collected they are reviewed against the laboratory established
acceptance limits specified in the data packages.
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 for radionuclide analyses when
water is present. During the reporting period, no surface water was present in Westwater
Canyon and therefore no surface water samples were collected. Sediment samples from
Westwater Canyon are taken in place of the Westwater Canyon surface water sample when
surface water is not available for sampling. If surface water samples are not collected from
8
Westwater Canyon a sediment sample will be collected in the third or fourth quarter of 2023.
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. During the reporting period, surface water was
present in the first and second quarters at Cottonwood Creek and samples were collected on
January 18, 2023, and April 27, 2023, respectively.
Graphical presentation of the water 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 H of this report. The 2023 data results are within the variation of
previous sampling episodes and are comparable to historic results. For graphical illustration
purposes, values reported at less than the prescribed detection limit were plotted as 0.0 pCi/g
concentrations. 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
viewable depiction of location radionuclide information because the actual concentration below
the detection limit cannot be determined.
7.0 SOIL SAMPLING
In accordance with the Mill's EPM and License, surface soils will be collected during the third
quarter of 2023. The sampling results will be discussed in the July through December Semi-
Annual Effluent Report submitted to DWMRC on or before March 1, 2024.
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.
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
9
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 2023 for the
January through June 2023 reporting period. The April 2023 measurement was 0.6 pCi/(m2-sec ).
The full data report for the April 2023 Cell 2 radon flux sampling is provided in Attachment K.
It is important to note that Cell 2 Phase 1 cover placement/construction commenced in April

Air filters were collected from 1/03/2023 to 4/03/2023.
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4°C (±2°C)
Report Date: 05/15/23
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.

=====-------·
Lab measurement of analytes considered field parameters that require analysis within 15 minutes of sampling such as
pH, Dissolved Oxygen and Residual Chlorine, are qualified as being analyzed outside of recommended holding time.
Solid/soil samples are reported on a wet weight basis (as received) unless specifically indicated. If moisture corrected,
data units are typically noted as -dry. For agricultural and mining soil parameters/characteristics, all samples are dried
and ground prior to sample analysis.
The reference date for Radon analysis is the sample collection date. The reference date for all other Radiochemical
analyses is the analysis date. Radiochemical precision results represent a 2-sigma Total Measurement Uncertainty.

Energy Fuels Resources (USA) Inc
2nd Quarterly Air Analysis 2023
C23070164
Air filters were collected from 4/03/2023 to 7/03/2023.
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4°C (±2°C)
Report Date: 08/11/23
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.
SOIL/SOLID 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.

Lab measurement of analytes considered field parameters that require analysis within 15 minutes of sampling such as
pH, Dissolved Oxygen and Residual Chlorine, are qualified as being analyzed outside of recommended holding time.
Solid/soil samples are reported on a wet weight basis (as received) unless specifically indicated. If moisture corrected,
data units are typically noted as -dry. For agricultural and mining soil parameters/characteristics, all samples are dried
and ground prior to sample analysis.
The reference date for Radon analysis is the sample collection date. The reference date for all other Radiochemical
analyses is the analysis date. Radiochemical precision results represent a 2-sigma Total Measurement Uncertainty.

¥ The value in the MDC column is the sample-specific minimum detectable concentration. The MDC is based on the sample moisture, composition and other sample-specific variables The value in
parantheses is the method-specific lower limit of detection (LLD), which is a limit representing the detection capability of the measurement system. The LLDs in the data package are referred to as
the Reporting limit (RL),

five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control limit of +I-the
RL is used to evaluate the DUP result.
* Indicates that a Quality Control parameter was not within specifications.
For PS, PSD, and SDIL T results, the values listed are the measured amounts, not final concentrations.
Where the analytical method has been performed under NELAP certification, the analysis has met all of the
requirements of the NELAC standard unless qualified on the QC Summary.

RADON MONITORING GRAPHS AND DATA
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 Part 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
1 o-s 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 umealistic 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<-11439l -2.1963exp<-iJ38_6J + 1.2442exp<-1128Al
[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.

The radon measurement was performed with a closed alpha-track detector following the quality assurance guidance given in the ANSI/AARST protocols. The detector
container is manufactured from electrically conducting plastic. Through a small slit (filter), radon gas enters the detector. The track-detecting material (film) inside the
detector is hit by alpha particles generated by the radon entering the container and the decay products formed from it. On the film, the alpha particles make small tracks
which are enlarged through chemical etching and later counted in a microscope in order to determine the radon exposure.
Transit detectors are used for the return delivery of the high-sensitivity detectors in order to make a more accurate background subtraction.
Radonova Laboratories (P.O. Box 6522, SE-751 38 Uppsala, Sweden) is accredited (no. 1489) by SWEDAC to conduct radon-gas measurements using the closed
alpha-track detector method. The analysis equipment is checked daily and the detectors are calibrated at regular intervals. NRPP Licenses: 107831 AL, 107830 RT
Measured radon concentrations
For each detector, the measured value of the radon concentration is provided. For each value an uncertainty associated with the measurement to a 95% confidence level
is also provided. For example a measurement result of 4.0 ± 0.5 pCi/L means that the radon concentration is most likely contained in the range 3.5 -4.5 pCi/L. If the start
or end date of the measurement has not been provided, the radon concentration cannot be calculated. In such cases, the total exposure in pCi*days/L will be reported.
The reported measured values are related to the detectors as received by Radonova Laboratories. Detector deployment is not performed by Radonova Laboratories.
Measurement information such as monitoring period (dates) and placement location is provided to Radonova Laboratories by the end user. The presented results apply
only to the samples tested.
The average transit exposure has been subtracted in the reported radon concentrations.

The radon measurement was performed with a closed alpha-track detector following the quality assurance guidance given in the ANSI/AARST protocols. The detector
container is manufactured from electrically conducting plastic. Through a small slit (filter), radon gas enters the detector. The track-detecting material (film) inside the
detector is hit by alpha particles generated by the radon entering the container and the decay products formed from it. On the film, the alpha particles make small tracks
which are enlarged through chemical etching and later counted in a microscope in order to determine the radon exposure.
Transit detectors are used for the return delivery of the high-sensitivity detectors in order to make a more accurate background subtraction.
Radonova Laboratories (P.O. Box 6522, SE-751 38 Uppsala, Sweden) is accredited (no. 1489) by SWEDAC to conduct radon-gas measurements using the closed
alpha-track detector method. The analysis equipment is checked daily and the detectors are calibrated at regular intervals. NRPP Licenses: 107831 AL, 107830 RT
Measured radon concentrations
For each detector, the measured value of the radon concentration is provided. For each value an uncertainty associated with the measurement to a 9S% confidence level
is also provided. For example a measurement result of 4.0 ± 0.5 pCi/L means that the radon concentration is most likely contained in the range 3.5 -4.5 pCi/L. If the start
or end date of the measurement has not been provided, the radon concentration cannot be calculated. In such cases, the total exposure in pci•days/L will be reported.
The reported measured values are related to the detectors as received by Radonova Laboratories. Detector deployment is not performed by Radonova Laboratories.
Measurement information such as monitoring period (dates) and placement location is provided to Radonova Laboratories by the end user. The presented results apply
only to the samples tested.
The average transit exposure has been subtracted in the reported radon concentrations.

1. INTRODUCTION
During April 4-5, 2023 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 for Cell 2 on a semiannual basis. This report presents the radon flux
measurements results for Cell 2 that represent the first half of the year 2023.
Tellco was contracted to provide canisters and charcoal, laboratory sample analysis, report preparation,
and field work oversight. Energy Fuels personnel performed the canister placement and retrieval and
support 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 consisting of 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 from 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 of 20 picoCuries per meter squared per second (pCi/m2-s). A representative from the
Utah Department of Environmental Quality was present on April 5, 2023 during the performance of the
Cell 2 radon flux measurements.
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, 2022). 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 ½ inch thick layer of foam and secured with a
retaining ring under 1 ½ inches of foam (see Figure I, page 9).
1
One hundred sampling locations were distributed throughout the Cell 2, 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 approximately 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 April 4, 2023 one hundred 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 with similar sample identification numbers (IDs). 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., H0l...Hl00). This ID was written on an adhesive
2
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 subsequently 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 oflocal 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 April 5, 2023 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 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
Energy Fuels maintains an onsite rain gauge to monitor rainfall at the White Mesa mill site.
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.
• None of the canister seals were washed away by rainfall, 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 thick 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-O-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 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 NaI 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 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, 2022) 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 had an arithmetic average of approximately 0.03 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 performed by replicating
analyses of individual field samples (see Appendix B). These recount measurements comprised
approximately IO percent of the total number of samples analyzed. The precision of recount
measurements, expressed as relative percent difference (RPD), for sample results values that were
above I pCi/m2-sec ranged from approximately 3.5 percent to 5.6 percent, with an average of
approximately 4.5 percent. This complies with the precision objective of+/-IO 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 -1.5 percent to + 1.1 percent. The arithmetic average bias of the lab control
sample measurements was approximately -0.2 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 as follows:
Equation 8.1:
pCi Rn-222/m2sec = [Ts* A *b*O.stdl91 ,3))
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:
0.1702, for M-01/0-21 and
0.1706, for M-02/0-20
d = decay time, elapsed hours between sample mid-time and count mid-time
A = area of the canister, m2
Equation 8.2:

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.
6
(b) The mean radon flux for the total uranium mill tailings pile shall be calculated as follows:
A1
Where: J5 = Mean flux for the total pile (pCi/m2-s)
Ji = Mean flux measured in region i (pCi/m2 -s)
Ai = Area ofregion 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
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 Cell 2 region at the site is as follows:
Cell 2 -Cover Region = 0.6 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 Cell 2 is as follows:
Cell 2 = 0.6 pCi/m2-s
(0.6)(270,624) = 0.6
270,624
As shown above, the arithmetic mean of the radon flux rate measurements for Cell 2 representing the
first half of the year 2023 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. The map was produced
by Tellco.
