WHITE MESA URANIUM MILL
SEMI-ANNUAL EFFLUENT REPORT, JULY THROUGH DECEMBER 2020
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.
UT1900479 (the "License") and guidelines developed by the United States Nuclear
Regulatory Commission ("NRC") (NRC Regulatory Guide 4.14, Radiological Effluent
and Environmental Monitoring at Uranium Mills-Rev. 1, ML003739941), 1980).
1.1 Modifications to the Monitoring Programs
As stated above, the monitoring programs implemented to date are consistent with the
Mill's License and guidelines developed by the NRC and described in Regulatory Guide
4.14. The Mill's License modifies and expands the effluent monitoring programs
implemented at the Mill beyond what is regularly required by NRC Regulatory Guide
4.14. Specific changes to the individual monitoring programs are discussed in the
subsequent sections of this report.
In a letter dated July 23, 2014, DWMRC stated that because "Tailings Cell 2 is no longer
in operation (receiving tailings), the Division of Air Quality and the Division of
Radiation Control agree that Subpart W NESHAPs requirements (40 CFR Part 61) no
longer apply; however, at this phase of cell 2 closure activities, the requirements of 10
CFR Part 40, Appendix A, Criterion 6 do apply." The July 23, 2014 letter further
requires that radon flux measurements for Cell 2 be collected semi-annually in
accordance with methodology specified in 40 CFR Part 61, Appendix B, Method 115 and
that the measured results be included in the Semi-Annual Effluent Reports submitted to
DWMRC. As a result of the July 23, 2014 letter, Cell 2 radon flux monitoring data are
reported herein. Additional details regarding the monitoring and data collection activities
for the Cell 2 radon flux are included in Section 9.0.
As specified by the License and the documents described above, the Mill monitors the
following environmental media and conditions:
a) Airborne particulate radionuclide concentrations obtained from the following
sampling stations:
• North, east and south of the Mill Site: BHV-1, BHV-2, and BHV-8
(north), BHV-5 and BHV-7 (east), and BHV-4 (south). BHV-1 and BHV-
8 serve as surrogates for the nearest resident (BHV-1 and BHV-8 are
1
approximately 1.2 miles north of the Mill, but approximately 0.4 miles
closer to the Mill than the nearest resident);
• A background location distant to and west of the Mill (BHV-3) that was
monitored for airborne particulates up until November, 1995 (at which
time background was established), which is no longer monitored for air
paiticulates; and
• A station specifically requested by the White Mesa Ute Community south
of the Mill Site (BHV-6);
b) External ( direct) gamma radiation measured at air monitoring stations BHV-1,
BHV-2, BHV-3, BHV-4, BHV-5, BHV-6, BHV-7, and BHV-8;
c) Vegetation at three site periphery locations, for uptake of radionuclides;
d) Stack release rates from the Mill's air emissions sources;
e) Surface water at Cottonwood Creek and, when flowing, Westwater Creek, both
located west of the Mill;
f) Soil radionuclide activity during the third quarter of each year;
g) Radon-222 at the air particulate monitoring stations (BHV-1 through BHV-8);
h) Meteorological conditions;
i) Radon flux of the Cell 2 cover as specified by the DWMRC in coITespondence
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
1 Groundwater sampling and seeps and springs sampling are reported separately pursuant to the Mill's State
of Utah Ground Water Discharge Permit No. UGW370004, and are not included with this report.
2
four environmental air sampling locations, an additional station (BHV-6) was installed at
the request of the White Mesa Ute Community. This station began operation in July of
1999 and provides airborne particulate information in the southerly direction between the
Mill and the White Mesa Ute Community.
As stated in Section 1.1 above, the air 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.
3
The analytical results of radionuclide particulate sampling for each monitoring station
operated during this reporting period are provided in Attachment B under separate
sampling station attachment tabs (Tabs 1-8). Each tab contains graphical illustrations of
the radionuclide concentrations in log-scale presentation format. The graphs display
reported data over time since the 1981 inception of the Mill's environmental air
particulate monitoring program or the installation of the locations, whichever is
appropriate. The actual analytical results (and associated QA/QC information) reported
by the laboratory for the reporting period are provided under Attachment C. In addition to
the analyses for radionuclides, particulate loading is determined for each filter and
composited as a quarterly mass-loading estimate for review purposes only. Graphs
showing particulate loading at each station and the underlying data are included as
Attachment D.
Analytical data were reviewed against the laboratory established acceptance limits
specified in the data packages. The analytical data are usable for their intended purpose.
Any deviations noted did not affect the quality or usability of the data.
For graphical illustration purposes, values reported at zero, values reported at less than
the prescribed detection limit ( < 1 x 10·16 uCi/ml), and missing values were plotted as 1 x
10·16 uCi/ml concentrations. Where other "less than" values were indicated (i.e., where
detection limits for the data varied from 1 x 10·16 uCi/ml), the detection limit
concentration was utilized for plotting the data point. This graphing convention is not
utilized to formulate station average information, nor is it intended as a precedent for data
treatment. Rather, the intent is to provide a conservative viewable depiction of site
airborne radionuclide information. This is considered to be a conservative approach,
because the actual concentration below the detection limit cannot be determined and, as a
result, the plotted point will be at the same or a higher concentration than the actual
activity concentration of the collected sample.
2.3 General Observations
The results of environmental air monitoring for this semi-annual period indicate that for
all radionuclides at all monitoring stations, airborne radionuclide particulate activity
concentrations were well below regulatory Effluent Concentration Limits ("ECL's") and
the Mill's ALARA goals, which are set at 25% of the ECLs, except as noted below.
It is 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
4
are carried with the air. Pb-210 is the longest lived of these decay products and is the
decay product of the shorter-lived radon progeny. As such, it accumulates as an electrical
attachment on the natural ambient dust in the atmosphere and is generally measured at
elevated activity when compared to local decay-chain parent radionuclide activity,
regardless of uranium milling activity. At the Mill's BHV air monitoring stations, all
dust (ambient natural and mill derived) is collected by the sample filter. Because of the
natural elevation of Pb-210 accumulated as an attachment to the naturally occurring
ambient dust particles collected by the air sampling equipment, Pb-210 is commonly
elevated and in disequilibrium when compared to parent radionuclide activity, regardless
of the Mill's presence. By way of illustration, average ground-level concentrations have
been reported for selected States (NCRP Report 94, 1992) and are summarized in Table 1
in the Tables Tab of this report, demonstrating that elevated Pb-210 activity is present
where no uranium milling operations are located nearby. In April 1977, prior to Mill
construction and Mill operations, air particulate Pb-210 was measured at the Mill site to
be l.3E-14 uCi/rnl (13.0E-3 pCi/m3)2.
2.4 Site Specific Sampling Data
The results of airborne particulate monitoring for the period (without background
subtraction) are provided by sampling station and radionuclide in Tables 2 through 6 in
the Tables Tab of this report. Along with these data, the tables present comparative
ECL' s and the ECL percentage measured at each of the monitoring stations sampled
during the period. A review of these data support the conclusion that airborne particulates
are well controlled at the Mill. In all cases, the measured activity concentrations were
well within the ECL, as well as the Mill's ALARA goal (i.e. 25% of the ECL). Lower
Limits of Detection consistent with NRC Regulatory Guide 4.14 were maintained by the
Mill's contract analytical laboratory for this reporting period.
The data obtained since program inception in 1981 indicates that only one individual
quarterly measurement (Th-230 at BHV-5 for the 2nd Quarter of 1996) has ever exceeded
the ECL at the Mill. While it is important to consider and evaluate an individual
measurement exceeding the ECL, it is the average annual concentration that is of primary
significance for public dose estimation purposes. In that instance, the average annual
concentration of Th-230 for BHV-5 in 1996 was well below the ECL. Data obtained
since program inception in 1981 also indicate that, with very few exceptions, the gross
(background inclusive) measurements do not exceed the site's ALARA goal (i.e. only ten
of the several thousand total gross radionuclide determinations to date exceeded the
Mill's self-imposed 25% ALARA goal).

2.5 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 CPR 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.
In order to determine whether or not detection equipment has improved since 1995, EFRI
voluntarily began ambient Radon-222 monitoring at the BHV stations in 2013. The
Radon-222 data collected from 2013 through present are presented in Attachment J. As
stated in Section 1.1 above, the Mill's effluent monitoring programs were expanded in
2014. The expanded monitoring programs require the collection of Radon-222 data at all
of the BHV stations. For the BHV stations EFRI calculated ECLs using methodology
shown in Attachment J. The calculated ECLs for all of the BHV stations are included on
the data table included in Attachment J. The radon-222 results are below the calculated
ECLs and within the range of historic levels as shown in Attachment J.
Radon-222 monitoring is completed using detectors with an effective reporting limit of
0.06 pCi/L. Field blank detectors are collected quarterly and the results (with
background included) are included in Attachment J.
During the reporting period, one field blank was collected during each quarter. Field
blanks are opened at the beginning of the monitoring period and immediately sealed in
the manufacturer supplied packaging. The field blanks are stored in the environmental
office until the end of the monitoring period, when they are packaged with the field
samples and shipped to the laboratory for processing. While relatively low concentrations
were reported for the field blanks, the field blank data show detections which are greater
than the highest detection reported for any of the samples collected at the high volume
stations. The field blank data have been consistently higher than the samples. Despite
the detections reported for the field blanks, there is no indication that the results reflect
contamination during shipping. If the detections on the field blanks indicated
contamination resulting from shipment, then all of the detectors would be affected in the
same manner and the sample data are below the field blank levels. It appears that the
field blanks have been affected by the storage prior to shipping. EFRI is conducting an
investigation into the possible causes of the anomalous field blank detections.
6
3.0 EXTERNAL RADIATION (DIRECT GAMMA)
Gamma exposure rate estimates were measured for the 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, 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.
The results for this period indicate that above background measurements for stations
BHV-2, BHV-4, BHV-5, BHV-6, BHV-7, and BHV-8 are within historic levels.
4.0 VEGETATION SAMPLES
The NRC Regulatory Guide 4.14 requires that three samples be collected during the
grazing season, without specifying exact months or times during the season. Two samples
were collected during the January through June reporting period. The third sample was
be collected on October 7, 2020. As noted in Section 1.1, Amendment 7 and the
associated RFI expanded the vegetation sampling program through the addition of Th-
232 and U-Nat.
During the January through June reporting period, samples were collected on April 22,
and May 12, 2020. During the July through December reporting period, a sample was
collected on October 7, 2020. The data from the sampling events are included in
Attachment F.
Graphical log-scale presentation of the vegetation sampling results, together with the
analytical results reported by the Mill's contract laboratory (including QA/QC
information) for this sampling period, are included as Attachment F of this report. The
2020 data results are within the variation of previous sampling episodes.
Analytical data were reviewed against the laboratory established acceptance limits
specified in the data packages. The analytical data are usable for their intended purpose.
Any deviations noted did not affect the quality or usability of the data.
7
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:
Stack Sampling Requirements
Grizzly North and/or Yellowcake Vanadium South Packaging Vanadium Frequency Baghouse Packaging
Stack Yellowcake Baghouse Dryer Stack Stack Dryer Stacks 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,

and Th-228. and Th-228. and Th-228. and Th-228. and Th-228.
The south yellowcake dryer and yellowcake baghouse operated during the third and
fourth quarters. The north yellowcake dryer has not been in operation since the third
quarter of 2012, and therefore, has not been sampled since it was last in operation.
The vanadium dryer and vanadium baghouse did not operate during the reporting period.
The analytical results of stack sampling conducted in the reporting period, as well as for
the previous two quarters, are provided in Table 8 in the Tables Tab of this report. The
actual analytical results reported by the laboratory for the reporting period (third and
fourth quarters 2020) are provided in Attachment G to this report.
It is also important to note that uranium stack effluent concentrations are not comparable
to environmental air sampling station ECLs for regulatory compliance purposes. The
ECL is a limit that applies to the receptor locations and is not applicable to effluents from
mill processes on the Mill site. These stack release data are more appropriately utilized
for dose modeling purposes, and dose modeling is not computed for semi-annual
reporting purposes.
Analytical data were reviewed against the laboratory established acceptance limits
specified in the data packages. The analytical data are usable for their intended purpose
8
and within historic ranges. Any deviations noted did not affect the quality or usability of
the data.
6.0 SURFACE WATER MONITORING
Under the License, Part 11.2.B surface water samples are required to be obtained
annually from Westwater Canyon and semi-annually from Cottonwood Creek. Sediment
samples from Westwater Canyon are taken in place of the Westwater Canyon surface
water sample where surface water is not available for sampling. Westwater Canyon was
dry throughout 2020 and a sediment sample was collected August 31, 2020. The data for
Westwater sediment are included in Attachment H.
The Mill's EPM requires that samples from Cottonwood Creek be analyzed for TDS and
total suspended solids ("TSS") quarterly, and the License, Part 11.2.B requires that
samples from Cottonwood Creek be analyzed for dissolved and suspended radionuclides
including Gross Alpha, U-nat, Ra-226, and Th-230 semi-annually. In accordance with
these requirements, Cottonwood Creek was sampled for TDS and TSS during the third
quarter. No sample was collected during the fourth quarter because there was no water
present during the quarter.
The field data sheets for the surface water sampling events, along with graphs showing
historic results are included as Attachment H.
Analytical data were reviewed against the laboratory established acceptance limits
specified in the data packages. No data issues were noted and the data are usable for the
intended purpose.
7.0 SOIL SAMPLING
As mentioned in Section 1.1 above, specific changes to the individual monitoring
programs have been made.
In accordance with the Mill's EPM, 52 surface soils were collected in August 2020. The
soil samples were analyzed, on a dry basis, for Ra-226, U-nat, Pb-210, and Th-232. The
results of these samplings indicate that soil activity levels at the air monitoring stations
remain low and within the range of historic levels. A graphical presentation of the soil
results, together with analytical sample results for the August 2020 sampling event are
provided in Attachment I.
Analytical data were reviewed against the laboratory established acceptance limits
specified in the data packages. The analytical data are usable for their intended purpose
and are within historic ranges. Any analytical deviations noted did not affect the quality
or usability of the data.
9
Field duplicate sample results were assessed as required by the SOP. Duplicate results
were within the acceptance limits specified in the SOP except as noted in Table 1-3.
Field duplicate results are shown in Attachment I.
8.0 METEOROLOGICAL MONITORING
As in prior reporting periods, an independent contractor has prepared the White Mesa
Mill Semi-annual Meteorological Monitoring Report for the reporting period. This
information is retained at the Mill site for agency review.
9.0 CELL 2 RADON FLUX
The July 23, 2014 letter, DWMRC stated that because "Tailings Cell 2 is no longer in
operation (receiving tailings), the Division of Air Quality and the Division of Radiation
Control agree that Subpart W NESHAPs requirements (40 CFR Part 61) no longer apply;
however, at this phase of cell 2 closure activities, the requirements of 10 CFR Part 40,
Appendix A, Criterion 6 do apply."
Further, the DWMRC July 23, 2014 letter states that "since the MILDOS-Area Models
that have been run to show compliance with dose limits for releases from the Mill were
based on a limit of 20 picocuries per square meter second (pCi/m2-sec), in order to ensure
compliance with previously analyzed conditions, the DWMRC will require the licensee
to continue to measure the radon flux in accordance with [the latest revision of] 40 CFR
61, Appendix B, Method 115, "Monitoring for Radon-222 Emissions". The measured
radon flux for Cell 2 shall not exceed a value of 20 (pCi/m2-sec) until a new MILDOS-
Area Model to analyze a higher radon flux is completed and demonstrates compliance
with dose limits based on the releases from the Mill. As required by Method 115, a
minimum of 100 measurements are required and shall be performed on a semi-annual
basis."
Per the requirements detailed above, EFRI sampled Cell 2 radon flux in April 2020 for
the January through June 2020 reporting period and in October for the July through
December rep01ting period. The April 2020 measurement was 0.9 pCi/(m2-sec). The
October 2020 measurement was 3.9 pCi/(m2-sec). Both of the 2020 measurements were
below the 20.0 pCi/(m2-sec) standard. The full data report for the October 2020 Cell 2
radon flux sampling is provided in Attachment K. The full data report for the April 2020
Cell 2 radon flux sampling is provided in Attachment K of the January through June
SAER which was submitted on August 25, 2020.
The 2020 average radon flux is 2.4 pCi/(m2-sec) which is the arithmetic average of the
April 2020 measurement of 0.9 pCi/(m2-sec) and the October measurement of 3.9
pCi/(m2-sec). The arithmetic average is below the 20.0 pCi/(m2-sec) standard.

It is important to note that Cell 2 Phase 1 cover placement/construction commenced in
April 2016 and was completed in April 2017. The Phase 1 cover activities include the
placement and compaction of approximately 4.5 feet of soil materials.

ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4°C (±2°C)
Report Date: 11 /16/20
CASE NARRATIVE
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand
delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun .
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
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.

ORIGINAL SAMPLE SUBMITIAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4°C (±2°C)
Report Date: 02/10/21
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, Alrazine 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 s1~rvice. 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.
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).

¥ 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).

INTRODUCTION
Test Purpose
This test project was conducted to determine the total radionuclide emissions from the South
Yellow Cake Scrubber and the Yellow Cake Dryer Baghouse exhausts in te1ms of Curies per dry
standard cubic foot (Ci/dscf).
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
Yellow Cake Dryer Baghouse. The packaging enclosure also discharges into the Yellow Cake
Dryer Baghouse. The South Yellow Cake (SYC) dryer was the only operating dryer at the time
of the test. The North Yellow Cake dryer is currently not operational.
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 13-14, 2020 and the second run on
July 14-15, 2020.
One run was completed on the Yellow Cake Dryer Baghouse July 14, 2020.
Pollutants Tested and Methods Applied
The tests were a determination of radionuclide emissions in accordance with EPA Method 5/114.
The tests for the SYC and the Yellowcake Dryer Baghouse were for the following radionuclides:
Th-228, Th-230, Th-232, U-234, U-235, U-238, Pb-210, Ra-226 and Ra-228.
Test run filters and front wash residues were sent to Inter-Mountains Labs located in Sheridan,
Wyoming for radionuclide analysis.

SAMPLING AND ANALYTICAL PROCEDURES
Sampling Port Location
The inside diameter of the South Yellow Cake Scrubber stack was 12.75 inches. The two, four-
inch diameter sample po1t were located 28.24 diameters (30 feet) downstream from the last
disturbance and 6.59 diameters (7 feet) upstream from the next disturbance. Figure 1 in Appendix
D is a schematic of the stack.
The inside diameter of the Yellow Cake Dryer Baghouse stack was 16.0 inches. The two, four-
inch diameter sample ports were located 28.38 diameters (454 inches) downstream from the last
disturbance and 3.56 diameters (57 inches) upstream from the next disturbance. The sample port
locations are depicted in Figure 2 in Appendix D.
Sampling Point Location
Table Ill shows the distance of each sampling point from the inside wall according to EPA
Method 1. Each point was marked with a wrapping of glass tape and numbered. These points
were determined by measuring the distance from the inside wall.

To determine the actual emission rates for this stack, 40 CFR 60, Appendix A, Methods 1-5/114
were followed.
All sampling trains were made of inert materials (Teflon, stainless steel and glass) to prevent
interference of the sampled gas and particulate. The stack analyzers used to conduct Methods 1-
5/114 are constructed to meet the specifications outlined in the CFR. The temperature sensors
6
were K-type thermocouples. Heater, vacuum, and Pitot line connections were designed to be
interchangeable with all units used by the tester. A 3 I 6 stainless steel probe liner was used for the
tests. Figure 4 in Appendix Eis a sketch of the Methods 5/114 sampling train.
Sample boxes were prepared for testing by following the prescribed procedures outlined in
Methods 5/ 114.
Sampling and Analytical Procedures
All sampling and analytical test procedures were as specified in 40 CFR 60, Appendix A,
Methods 5/114.
Quality Assurance
All equipment setup, sampling procedures, sample recovery, and equipment calibrations were
carried out according to the procedures specified in 40 CFR 60 and the Quality Assurance
Handbook/or Air Pollulion Measurement Systems.

CASE NARRATIVE
Report ID: S2007281001
Samples SYC scrubber R1 Filter & Beaker 23.25. SVC scrubber R2 Filter & Beaker 26,27 and YC Dryer Baghouse Filter &
Beaker 24 were received on July 20, 2020.
All samples were received and analyzed within the EPA recommended holding times. except those noted below in this case
narrative. Samples were analyzed using the methods outlined in the following references:
"Standard Methods For The Examination of Water and Wastewater". approved method versions
Test Methods for Evaluating Solid Waste. Physical/Chemical Methods. SW-846, 3rd Edition
40 CFR Parts 136 and 141
40 CFR Part 50. Appendices B, J, L. and 0
Methods indicated in the Methods Update Rule published in the Federal Register Friday, May 18. 2012
ASTM approved and recognized standards
All Quality Control parameters met the acceptance criteria defined by EPA and Pace Analytical (Formerly Inter-Mountain
Laboratories) except as indicated in this case narrative.
Qualifiers by sample
MS-2178 -Radium 226 Air Filter Analysis/Radium 226 -Spike Recovery outside accepted recovery limits
MSD-2178 -Radium 226 Air Filter Analysis/Radium 226 -Spike Recovery outside accepted recovery limits
The uranium isotopes U234, U235, and U238 ratios are typical for the analysis of natural uranium. The quality checks for
mass balance of both uranium and thorium meet expectations.
The Regulatory Required Detection Limit (RRDL) was not met for thorium species due to procedureal, matrix and expected
air volumes of 6.000.000 ml.

INTRODUCTION
Test Purpose
This test project was conducted to determine the total radionuclide emissions from the South
Yellow Cake Scrubber and the Yellow Cake Dryer Baghouse exhausts in tei'nls of Curies per dry
standard cubic foot (Ci/dscf).
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 a
common hopper located in the packing area. The packing area discharges through the yellow
cake dryer baghouse. The South Yellow Cake (SYC) dryer was the only operating dryer at the
time of the test. The North Yellow Cake dryer is currently not operational.
Stack schematics are shown as Figures I and 2 in Appendix D.
Test Dates
The first test run on the SYC Scrubber was completed December 28-29, 2020 and the second run
on December 29-30, 2020.
One run was completed on the Yellow Cake Dryer Baghouse December 28, 2020.
Pollutants Tested and Methods Applied
The tests were a determination of radionuclide emissions in accordance with EPA Method 5/114.
The tests for the SYC and the Yellowcake Dryer Baghouse were for the following radionuclides:
Th-228, Th-230, Th-232, U-234, U-235, U-238, Pb-210, Ra-226 and Ra-228.
Test run filters and front wash residues were sent to Pace Analytical located in Sheridan,
Wyoming for radionuclide analysis.

SAMPLING AND ANA LYTICAL PROCEDURES
Sampling Port Location
The inside diameter of the South Yellow Cake Scrubber stack was 12.75 inches. The two, four-
inch diameter sample port were located 28.24 diameters (30 feet) downstream from the last
disturbance and 6.59 diameters (7 feet) upstream from the next disturbance. Figure l in Appendix
D is a schematic of the stack.
The inside diameter of the Yellow Cake Dryer Baghouse stack was 16.0 inches. The two, four-
inch diameter sample ports were located 28.38 diameters (454 inches) downstream from the last
disturbance and 3.56 diameters (57 inches) upstream from the next disturbance. The sample port
locations are depicted in Figure 2 in Appendix D.
Sampling Point Location
Table III shows the distance of each sampling point from the inside wall according to EPA
Method 1. Each point was marked with a wrapping of glass tape and numbered. These points
were detennined by measuring the distance from the inside wall.

To determine the actual emission rates for this stack, 40 CFR 60, Appendix A, Methods 1-5/ 114
were followed.
All sampling trains were made of inert materials (Teflon, stainless steel and glass) to prevent
interference of the sampled gas and particulate. The stack analyzers used to conduct Methods 1-
5/114 are constructed to meet the specifications outlined in the CFR. The temperature sensors
6
were K-type thermocouples. Heater, vacuum, and Pitot line connections were designed to be
interchangeable with all units used by the tester. A 3 I 6 stainless steel probe liner was used for the
tests. Figure 4 in Appendix Eis a sketch of the Methods 5/114 sampling train.
Sample boxes were prepared for testing by following the prescribed procedures outlined in
Methods 5/114.
Sampling and Analytical Procedures
All sampling and analytical test procedures were as specified in 40 CFR 60, Appendix A,
Methods 5/114.
Quality Assurance
All equipment setup, sampling procedures, sample recovery, and equipment calibrations were
carried out according to the procedures specified in 40 CFR 60 and the Quality Assurance
Handbook for Air Pollution Measurement Systems.

CASE NARRATIVE
Report JD: S2101051001
Samples SYC scrubber R1 Filter & Beaker #28, SVC scrubber R2 Filter & Beaker #29 & 31 and Yellow Cake BH Filter #30 &
Beakeer were received on January 7, 2021.
All samples were received and analyzed within the EPA recommended holding times, except those noted below in this case
narrative. Samples were analyzed using the methods outlined in the following references:
"Standard Methods For The Examination of Water and Wastewater", approved method versions
Test Methods for Evaluating Solid Waste, Physical/Chemical Methods, SW-846, 3rd Edition
40 CFR Parts 136 and 141
40 CFR Part 50, Appendices B, J, L, and 0
Methods indicated in the Methods Update Rule published in the Federal Register Friday, May 18, 2012
ASTM approved and recognized standards
All Quality Control parameters met the acceptance criteria defined by EPA and Pace Analytical (Formerly Inter-Mountain
Laboratories) except as indicated in this case narrative.
The uranium isotopes U234, U235, and U238 ratios are typical for the analysis of natural uranium. The quality checks for
mass balance of both uranium and thorium meet expectations.
The Regulatory Required Detection Limit (RRDL) was not met for thorium species due to procedureal, matrix and expected
air volumes of 6,000,000 ml.

ORIGINAL SAMPLE SUBMITIAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4°C (±2°C)
Report Date: 10/13/20
CASE NARRATIVE
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand
delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maicimum 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.
Radiochemical precision results represent a 2-sigrna Total Measurement Uncertainty.

* -Measurements obtained from BHV-3 have been designated as background due to BHV-3's remoteness from the Mill site. The
results in the table above are the above-background results with background (BHV-3) subtracted. Any negative values are
reported as zero for graphical purposes.
NA -Not Available -the canister was damaged. No data reported.
NS -Not Sampled -EFRI installed and began radon sampling at BHV-7 and BHV-8 in the fourth quarter of 2014.

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
10-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 unrealistic given the short half-lives of the nuclides considered and the short travel time to
the monitoring locations. Radon emanates from the ground ( or mill tailings) without daughters
present, and the daughters grow in over time. It is therefore necessary to evaluate radon daughter
equilibrium at each air monitoring station utilizing site-specific wind speed and distance
information to derive site-specific Effluent Concentration Limits (ECLs) for each station.
Such disequilibrium situations and alternative calculations are anticipated by the regulations and,
in particular, R313-15-302(3) provides a means by which the licensee may adjust the effluent
concentration values in 10 CFR Part 20 Appendix B, Table 2, which are incorporated by
reference into R313-15-302(2)(b)(i), to account for disequilibrium. The regulatory purpose of
such an adjustment is to appropriately take into account the actual characteristics of the measured
effluents, including radioactive decay equilibrium.
An established (EPA, 1986) outdoor equilibrium formula to determine the appropriate
Equilibrium Factor for use in calculating the ECL for disequilibrium conditions was used. The
EPA expression of the outdoor Equilibrium Factor (EF) is derived by the following equation:
EF = l.0-0.0479expC-ri4·39l _ 2.1963expc-,t3s.6) + l.2442expc-,t2S.4)
[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.

1. INTRODUCTION
During October 6-7, 2020 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 second half of the year 2020.
Tellco was contracted to provide radon canisters, equipment, and canister-placement personnel as well
as lab analysis of samples collected. Energy Fuels personnel provided support for loading and
unloading charcoal from the canisters. This report details the procedures employed by Energy Fuels
and Tellco to obtain the results presented in Section 9.0 of this report.
2. SITE DESCRIPTION
The White Mesa Mill facility is located in San Juan County in southeastern Utah, six miles south of
Blanding, Utah. The mill began operations in 1980 for the purpose of extracting uranium and
vanadium from feed stocks.
Cell 2, which has a total area of approximately 270,624 m2, has been filled and covered. This cell is
comprised of one region, a soil cover of varying thickness. There was no standing liquid and were no
exposed tailings within Cell 2 during this sampling.
3. REGULATORY REQUIREMENTS FOR CELL 2
Radon emissions from the uranium mill tailings 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 ).
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, 2020). 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 1h inch thick layer of foam and
secured with a retaining ring under 11/i inches of foam (see Figure 1, page 9).
One hundred sampling locations were distributed throughout Cell 2 (consisting of one region) as
depicted on the Sample Locations Map (see Figure 2, Appendix D). Each charged canister was placed
1
directly onto the surface ( open face down) and exposed to the surface for 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 ofradioactive decay.
After approximately 24 hours, the exposed charcoal was transferred to a sealed plastic sample
container (to prevent sample loss and/or further exposure during transport), identified and labeled, and
transported to the Tellco laboratory in Grand Junction, Colorado for analysis. Tellco personnel
maintained custody of the samples from collection through lab analysis.
Upon completion of on-site activities, the field equipment was alpha and beta-gamma scanned by
Energy Fuels Radiation Safety personnel for possible contamination resulting from fieldwork
activities. All of the field equipment used was subsequently released for unrestricted use.
5. FIELD OPERATIONS
5.1 Equipment Preparation
All charcoal was dried at 110°C before use in the field. Unused charcoal and recycled charcoal were
treated the same. 180-gram aliquots of dried charcoal were weighed and placed in sample containers.
Proper balance operation was verified daily by checking a standard weight. The balance readout
agreed with the known standard weight to within± 0.1 percent.
After acceptable balance check, empty containers were individually placed on the balance and the
scale was re-zeroed with the container on the balance. Unexposed and dried charcoal was carefully
added to the container until the readout registered 180 grams. The lid was immediately placed on the
container and sealed with plastic tape. The balance was checked for readout drift between readings.
Sealed containers with unexposed charcoal were placed individually in the shielded counting well,
with the bottom of the container centered over the detector, and the background count rate was
documented. Three five-minute background counts were conducted on ten percent of the containers,
selected at random to represent the "batch". If the background counts were too high to achieve an
acceptable lower limit of detection (LLD), the entire charcoal batch was labeled non-conforming and
recycled through the heating/drying process.
5.2 Sample Locations, Identification, and Placement
On October 6, 2020, 100 sampling locations were spread out throughout the Cell 2 covered region.
The approximate sampling locations that were established for previous samplings of Cell 2 were used
for the placement of the canisters, although the actual sample identification numbers (IDs) are
different. An individual ID was assigned to each sample point, using a sequential alphanumeric
system indicating the charcoal batch and physical location within the region (e.g., DOI. .. DlOO). This
ID was written on an adhesive label and affixed to the top of the canister. The sample ID, date, and
2
time of placement were recorded on the radon flux measurements data sheets for the set of one
hundred measurements.
Prior to placing a canister at each sample location, the retaining ring, screen, and foam pad of each
canister were removed to expose the charcoal support grid. A pre-measured charcoal charge was
selected from a batch, opened and distributed evenly across the support grid. The canister was then
reassembled and 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 of local borrow material.
Five canisters (blanks) were similarly processed and these canisters were kept inside an airtight plastic
bag during the 24-hour testing period.
5.3 Sample Retrieval
On October 7, 2020 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
A rain gauge was placed at Cell 2 to monitor rainfall during sampling; additionally, Energy Fuels
maintains an onsite rain gauge.
In accordance with 40 CFR, Part 61, Appendix B, Method 115:
• Measurements were not initiated within 24 hours of rainfall at the site.
• No rainfall occurred during the 24-hour sampling period after the canisters had been
deployed.
• All canister seals remained intact during the 24-hour sampling period and none of the
canisters were surrounded by water.
6. SAMPLE ANALYSIS
6.1 Apparatus
Apparatus used for the analysis:
• Single-or multi-channel pulse height analysis system, Ludlum Model 2200 with a
Teledyne 3" x 3" sodium iodide, thallium-activated (NaI(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-0-Gram balance with 0.1-gram sensitivity.
6.2 Sample Inspection and Documentation
Once in the laboratory, the integrity of each charcoal container was verified by visual inspection of the
plastic container. Laboratory personnel checked for damaged or unsealed containers and also checked
that the data sheet was complete.
All 100 of the sample containers and 5 blank containers inspected at the Tellco analytical laboratory
were ultimately verified as valid with no damaged or unsealed containers observed.
6.3 Background and Sample Counting
The gamma ray counting system was checked daily, including background and 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, 2020) were attained.
7.1 Sensitivity
A total of five blanks were analyzed by measuring the radon progeny activity in samples subjected to
all aspects of the measurement process, excepting exposure to the source region. These blank sample
measurements comprised approximately 5 percent of the field measurements. Analysis of the five
blank samples measured radon flux rates ranging from 0.07 to 0.09 pCi/m2-s, with an arithmetic
average of approximately 0.08 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 10 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 1 pCi/m2-sec ranged from approximately 0.0 percent to 8.6 percent, with an average of
approximately 3.7 percent. This complies with the precision objective of+/-10 percent.
7.3 Accuracy
Accuracy of field measurements was assessed daily by counting two laboratory control samples with
known Ra-226 content. Accuracy of these lab control sample measurements, expressed as percent
bias, ranged from approximately -0.8 percent to +0.9 percent. The arithmetic average bias of the lab
control sample measurements was approximately -0.1 percent (see Appendix A). This complies with
the accuracy objective of +/-10 percent bias.
7.4 Completeness
All 100 samples from the Cell 2 cover region were verified as valid, representing 100 percent
completeness, which complies with the completeness objective of 85 percent.
8. CALCULATIONS
Radon flux rates were calculated for charcoal collection samples using calibration factors derived
from cross-calibration to sources with known total activity with identical geometry as the charcoal
containers. A yield efficiency factor was used to calculate the total activity of the sample charcoal
containers. Individual field sample result values presented were not reduced by the results of the field
blank analyses.
5
In practice, radon flux rates were calculated by a database computer program. The algorithms utilized
by the data base program were as follows:
Equation 8.1:
pCi Rn-222/m2sec = [Ts* A *b*~_5cJl!JLi5J
where: N = net sample count rate, cpm under 220-662 ke V peak
Ts = sample duration, seconds
b = instrument calibration factor, cpm per pCi; values used:
0.1693, for M-01/D-21 and
0.1689, 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,20' = 2X -'--------------------x Sample Concentration
Equation 8.3:
LLD = 2.7 1 +(4.65)(S1.)
[Ts* A *b*Q,5(dl'J'i'.'"75l]
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:
0.1693, for M-01/D-21 and
0.1689, 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 fylean 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:
Ai
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)
A1 = 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 = 3.9 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 = 3.9 pCi/m2-s
(3.9)(270,624) = 3.9
270,624
As shown above, the arithmetic mean of the radon flux rate measurements representing the second
half of the year 2020 for Cell 2 at Energy Fuels' White Mesa milling facility is 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.
