2021 ANNUAL TAILINGS SYSTEM WASTEWATER SAMPLING REPORT
1.0 INTRODUCTION
This is the 2021 Annual Tailings System Wastewater Sampling Report for the Energy Fuels
Resources (USA) Inc. ("EFRI") White Mesa Mill (the "Mill"), as required under Part I.F.9 of the
Mill's State of Utah Groundwater Discharge Permit No. UGW370004 (the "Permit") and Section
6.0 of the Mill's Sampling and Analysis Plan for The Tailings Management System, Leak Detection
Systems and Slimes Drains, Revision: 3.0, dated July 8, 2016 (the "Sampling Plan") and approved
by the State of Utah Division of Waste Management and Radiation Control ("DWMRC") on
August 8, 2016.
Cell solution and slimes drain sampling is required under the Sampling Plan and Part I.E.10 of the
Permit to be conducted on an annual basis in August of each year for the solutions in Cells 1, 3,
4A, and 4B, the solutions in the slimes drains in Cells 2, 3, 4A, and 4B (for Cells 3, 4A and 4B
after the commencement of dewatering), the solutions in the leak detection system ("LDS") in Cell
4A and 4B and any detected solutions in the LDS in Cells 1, 2, and 3 at the time of the August
Sampling event. The results of the sampling event are required to be reported to the DWMRC
with the Mill's Third Quarter Groundwater Monitoring Report due December 1, of each year.
The 2021 sampling event was conducted September 1, 2021 at DWMRC's request to
accommodate their schedule.
2.0 SUMMARY OF MILL TAILINGS SYSTEM ACTIVITIES IN 2021
This section provides a brief description of the Mill's tailings management system, and any
changes that were made as a result of Mill activities during the reporting year. A description of
which systems were sampled is provided in Section 3.0.
The Mill is designed not to discharge to groundwater or surface waters. Instead, the Mill tailings
system utilizes tailings and evaporation cells for disposal, evaporation, and management of Mill
tailings, effluents, and other wastes as indicated below:
• Cell 1: dedicated to evaporation of Mill waste solutions;
• Cell 2: contains Mill tailings and has been closed to tailings disposal since 1995 and
1 le.(2) byproduct materials since 2000. Cell 2 Phase 1 cover placement commenced in
April 2016;
• Cell 3: contains Mill tailings and is in the final stages of filling. It also accepts other Mill
wastes and 1 le.(2) material from in-situ recovery ("ISR") operations;
• Cell 4A: receives Mill tailings and is used for evaporation of Mill solutions; and
• Cell 4B: is used for evaporation of Mill solutions.
1
2.1 Cell 1
Cell 1 is a 55-acre impoundment built in June of 1981. It operates as an evaporation pond which
receives solutions only. Cell 1 is equipped with a LDS. In 2021, Cell 1 received fluid from the
Mill process, storm water run-off, and Mill laboratory waste. The LDS in Cell 1 was dry in 2021.
2.2 Cell 2
Cell 2 is a 67-acre impoundment built in May of 1980. Cell 2 contains Mill tailings and has been
closed to tailings disposal since 1995 and lle.(2) byproduct materials since 2000. Cell 2 Phase 1
cover placement commenced in April 2016. Cell 2 is equipped with a LDS and a slimes drain. The
LDS was dry in 2021. As part of closure activities, EFRI began monitoring the slimes drain system
in 2008. The fluid from the slimes drain is pumped to Cell 4A. Cell 2 no longer receives any
solutions or solids.
2.3 Cell 3
Cell 3 is a 71-acre impoundment built in September 1982. Cell 3 is nearly full of solids. This cell
is equipped with a LDS and a slimes drain. The LDS was dry in 2021 and the slimes drain system
will be monitored once dewatering begins. In 2021, Cell 3 received solid Mill waste, some process
solutions, and solid 1 le.2 byproduct material from in situ recovery ("ISR") facilities.
2.4 Cell 4A
Cell 4A is a 40-acre impoundment built in 2008. This cell is equipped with a LDS and a slimes
drain. The slimes drain system will be monitored once dewatering begins. The LDS in Cell 4A
was sampled in 2021, as described below. In 2021, Cell 4A received solutions from the Mill
process, and some solid tailings sands.
2.5 Cell 4B
Cell 4B is a 40-acre impoundment built in 2011. It operates as an evaporation pond which receives
solutions only. No process fluids were sent to Cell 4B from the Mill in 2021.The LOS in Cell 4B
was sampled in 2021, as described below.
3.0 SAMPLING EVENTS AND SAMPLING METHODOLOGY
3.1 Sampling Events
Samples of solutions from Cells 1, 3, 4A, and 4B, the Cell 2 slimes drain and the Cell 4A and Cell
4B LDSs were collected on September 1, 2021.
In accordance with the Permit, DWMRC was notified of the sampling event, and a DWMRC
representative was present for a part of the sampling. The DWMRC representative collected split
sample aliquots at Cell 2 slimes drain.
2
Maps showing the locations of the solution and slimes drain and, when applicable, LDS sampling
locations are attached under Tab B. Table 1, included in the Tables Tab, provides an overview of
all solution monitoring samples collected during the current period and includes the sampling date,
laboratory report date, and the work order/lab set ID associated with the analytical data.
The Permit requires that the samples be analyzed for the water quality parameters listed in Table
2 of the Permit and SVOCs.
Additionally, in order to further characterize the radiological constituents and physical properties
of the solution, EFRI conducted voluntary analyses on the September 1, 2021 samples for radium-
226, thorium-228, thorium-230, thorium-232, uranium-233/234, uranium-235/236, uranium-238,
and specific gravity. The additional data from the September 1, 2021 sampling event are included
in separate data tables in Tab D. The gross alpha results have been evaluated and are included as
required. These additional data are included in this report for informational purposes only. EFRI
may or may not choose to continue these analyses in future sampling events.
3.2 Field Data
Attached under Tab A are copies of all of the field data sheets recorded in association with the
annual tailings system monitoring program. Sampling dates are listed in Table 1.
3.3 Sampling Methodology, Equipment and Decontamination Procedures
As noted in the DWMRC-approved Sampling Plan, Revision 3.0, dated July 8, 2016, field filtering
and preservation of metals and gross alpha sample aliquots was not completed due to safety
concerns associated with the filtering apparatus and the backpressure created by the increased
viscosity of these samples. The gross alpha and metals aliquots were filtered and preserved as
necessary by the analytical laboratory. It is important to note that field preservation of the samples
is to preclude biological growth and prevent the inorganic analytes from precipitating. Based on
past field data, the cell solutions (except Cell 3) and LDS and slimes drain samples are at a low
pH at the time of collection without additional preservative. The addition of acidic preservatives
in the field would add minimal if any protection from biological growth or precipitation.
3.3.1 Cells
Cell solution samples were collected as noted above, at the cell sampling stations shown on the
Figures in Tab B, using approved procedures described in the DWMRC-approved Sampling Plan,
Section 3.1.2.
Disposable or dedicated sampling equipment was used during this sampling event and, as such,
rinsate samples were not required.
3.3.2 Cell 2 Slimes Drain
Once a tailings cell has started the dewatering procedures, a sample will be collected from the
slimes drain system. At this time, Cell 2 is the only slimes drain that requires sampling. The
3
location of the slimes drain for Cell 2 is shown in Tab B. While Cells 3, 4A and 4B are equipped
with slimes drain sample locations, Cells 3 and 4A are still active and Cell 4B is being used as an
evaporation pond, and the slimes drains will not be pumped (and/or sampled) until dewatering
operations have commenced.
The Cell 2 slimes drain, shown on the Figures in Tab B, was sampled using a disposable bailer as
noted in the DWMRC-approved Sampling Plan, Section 3.1.3.
Due to the use of a disposable bailer, a rinsate sample was not required.
3.3.3 Cell 4A Leak Detection Systems
The Cell 4A LDS sample was collected from the sampling station shown on the Figures in Tab B
using a dedicated stainless steel bucket and ladle as noted in the DWMRC-approved Sampling
Plan, Section 3.2.2.
3.3.4 Cell 4B Leak Detection Systems
The Cell 4B LDS sample was collected from the sampling station shown on the Figures in Tab B
using a dedicated stainless steel bucket and ladle as noted in the DWMRC-approved Sampling
Plan, Section 3.2.2.
3.3.5 Cells 1, 2, 3,
The Cells 1, 2, and 3 LDSs were not sampled during the 2021 sampling event because the
systems were dry.
3.4 Field QC Samples
The field Quality Control ("QC") samples generated during this sampling event included one
duplicate and one trip blank per shipment to each laboratory which received samples for Volatile
Organic Compounds ("VOCs"). The duplicate sample (Cell 65) was submitted blind to the
analytical laboratory. As previously stated, no rinsate blanks were collected during this sampling
event as only dedicated or disposable equipment was used for sample collection.
3.5 Laboratory Results
All analytical results were provided by one of the Mill's two contract analytical laboratories, GEL
Laboratories ("GEL") or Energy Laboratories ("EL").
The analytical data as well as the laboratory Quality Assurance ("QA")/QC summanes are
included under Tab C.

4.0 QUALITY ASSURANCE AND DATA EVALUATION
The Permit requires that the annual tailings system wastewater sampling program be conducted in
compliance with the requirements specified in the Mill's approved White Mesa Uranium Mill
Groundwater Monitoring Quality Assurance Plan ("QAP"), the approved Sampling Plan and the
Permit itself. To meet these requirements, the data validation completed for the tailings system
wastewater sampling program and discussed in this Section utilized the requirements outlined in
the QAP, the Permit and the approved Sampling Plan as necessary. The Mill Quality Assurance
Manager ("QAM") performed a QA/QC review to confirm compliance of the monitoring program
with the requirements of the Permit, the QAP, and the Sampling Plan. As required, data QA
includes preparation and analysis of QC samples in the field, review of field procedures, an analyte
completeness review, and quality control review of laboratory data methods and data.
Identification of field QC samples that were collected and analyzed is provided in Section 3.4 and
4.3.1. Discussion of adherence to the Sampling Plan is provided in Section 4.1. Analytical
completeness review results are provided in Section 4.2. The steps and tests applied to check
laboratory data QA/QC are discussed in Section 4.3.
The analytical laboratories have provided summary reports of the analytical QA/QC measurements
necessary to maintain conformance with National Environmental Laboratory Accreditation
Conference ("NELAC") certification and reporting protocol. The analytical laboratory QA/QC
Summary Reports, including copies of the Chain of Custody forms for each set of Analytical
Results, follow the analytical results under Tab C. Results of review of the laboratory QA/QC
information are provided under Tab E and discussed in Section 4.3, below.
4.1 Adherence to Sampling Plan and Permit Requirements
On a review of adherence by Mill personnel to the QA/QC requirements, the QAM observed that
QA/QC requirements established in the Permit, the QAP, and the Sampling Plan were met, as
discussed below.
4.2 Analyte Completeness Review
All analyses required by the Permit Table 2 were completed. In addition, all cell solution samples
were analyzed for SVOCs as required by the Permit.
It is important to note that the SVOC analyses include Tentatively Identified Compounds ("TICs").
The SVOC compound 4-chlorophenol would be reported in the TIC data list if detected. 4-
chlorophenol was not detected.
4.3 Data Validation
The QAP and the Permit identify the data validation steps and data quality control checks required
for the tailings system wastewater monitoring program. Consistent with these requirements, the
QAM performed the following evaluations: a field data QA/QC evaluation, a receipt temperature
check, a holding time check, an analytical method check, a reporting limit check, a trip blank
5
check, a QA/QC evaluation of sample duplicates, a gross alpha counting error evaluation and a
review of each laboratory's reported QA/QC information. Each evaluation is discussed in the
following sections. Data check tables indicating the results of each test are provided under Tab E.
4.3.1 Field Data QA/QC Evaluation
The QAM performs a review of all field recorded data to assess adherence with QAP, Permit, and
Sampling Plan requirements. The assessment involved review of the Field Data sheets. Review of
the Field Data Sheets noted that all requirements for field data collection were met.
4.3.2 Holding Time Evaluation
QAP Table 1 identifies the method holding times for each suite of parameters. Sample holding
time checks are provided under Tab E. All samples were analyzed within the required holding
time.
EL reported two results for Total Dissolved Solids ("TDS") for Cell 1, Cell 4B and Cell 65
(duplicate sample of Cell 1). One analysis was completed within holding time and one was
completed beyond the holding time. The laboratory noted that there were potential issues with the
analyses completed within the holding time due to the sample matrix interferences. The results of
both analyses appeared to be comparable and within analytical laboratory error. Comparison of
the two TDS results indicates a 2% or less difference between the in holding time sample and the
out of holding time sample and therefore the initial results are acceptable for use.
It is important to note that pH is analyzed by the laboratory and is not measured in the field because
the acidic nature of the samples requires a more robust meter than what is available for field use.
In most circumstances pH is measured at the time of sample collection and a holding time is not
assessed. If pH is not measured at the time of collection, a 15-minute time limit is set. EL flagged
the pH results with an "H" flag because the pH was measured beyond the 15-minute limit. This
does not affect the usability of the data, as the sample matrices are stable and pH is collected for
informational purposes only and there are no compliance criteria for pH measurements.
4.3.3 Laboratory Receipt Temperature Check
Chain of Custody sheets were reviewed to confirm compliance with the Permit. Sample receipt
temperature checks are provided under Tab E. All samples were received within the required
temperature limit.
4.3.4 Analytical Method Check
All analytical methods reported by both laboratories were checked against the required methods
specified in Table 1 of the QAP. It is important to note that neither the QAP nor the Permit specify
a method for laboratory pH or conductivity. The QAM verified that the laboratory pH and
conductivity methods used by the laboratory were appropriate and provided accurate data.
6
Table 1 of the QAP does not specify a method for SVOCs because SVOCs are not routinely
collected in the Mill groundwater samples. The GWDP requires that tailings and slimes drain
samples shall include the SVOCs identified in EPA Method 8270D. The GWDP does not specify
that EPA Method 8270D be used for analysis, only that the compounds specified in that method
be included in the analytical list. All of the SVOCs in the GWDP-specified list were included in
the analytical data The analytical data are included in Tab C.
Analytical method check results are provided in Tab E.
4.3.5 Reporting Limit Evaluation
All analytical method reporting limits reported by both laboratories were checked against the
reporting limits specified in the Permit. Section I.E.4 of the Permit requires the following
Reporting Limits:
"all water quality analyses reported shall have a minimum detection limit or reporting limit
that is less than or equal to the respective:
i. Ground Water Quality Standards ("GWQS") concentrations defined in Table 2 of
this Permit,
ii. For TDS, Sulfate, and Chloride, the Minimum Detection Limit for those constituents
for Cell solution monitoring will be as follows: 1,000 mg/L, 1,000 mg/L, and 1 mg/L,
respectively, and
iii. Lower limits of quantitation for groundwater for semi-volatile organic compounds
listed in Table 2 of EPA Method 8270D, Revision 4, dated February, 2007."
Reporting limits are provided in Tab E. There are several constituents that do not have specified
reporting limits in either the Permit or EPA Method 8270D. The reporting limits established by
the laboratory are reported in the data packages. The reporting limits are comparable to other
analytes in the same method based on the same matrix. The reporting limits used by the laboratory
are considered acceptable based on the matrix and known difficulties caused by the sample matrix.
The VOCs and all of the SVOCs had reporting limits that exceeded the reporting limits listed in
the permit or the method respectively.
The VOCs that had reporting limits that exceeded the reporting limits are:
• Methylene chloride in Cell 1, Cell 2 Slimes, Cell 3, Cell 4A, Cell 4A LDS, Cell 4B, Cell
4B LDS -2021 reporting limit= 25 ug/L
All samples had methylene chloride RLs above the permit required RL of 5 ug/L. These
exceedances were likely the result of dilutions necessary to address the matrix interferences
inherent in these samples. The exceedances do not affect the quality or usability of the data
7
because the results of this sampling provide an "inventory" of cell composition and are not used
for comparison to regulatory limits.
The reporting limits for the SVOCs exceeded the recommended RLs in Method 8270D. GEL
provided both a method detection limit ("DL") and RL. The DL is based on the sample
composition and other sample-specific variables such as TDS and pH. Method 8270D provides
"recommended" quantitation limits for water samples. The tailings solution matrix is not
comparable to routine groundwater samples and require dilutions to address these matrix
interferences. The laboratory will report detections to the DL and therefore that is the lowest limit
for reporting (i.e. the RL). These RL exceedances were likely the result of dilutions necessary to
address the matrix interferences inherent in these samples. The exceedances do not affect the
quality or usability of the data because the results of this sampling provide an "inventory" of cell
composition and are not used for comparison to regulatory limits.
In addition, several sets of sample results had the reporting limit raised for at least one analyte due
to sample dilution. In all cases the reported value for the analyte was higher than the increased
detection limit. In the case of Cell 1/Cell 65, thallium and lead results, EL reported results at too
high a dilution, therefore EFRI requested EL reanalyze those two analytes at a lower dilution.
Thallium was also reanalyzed for Cell 3, Cell 4A, Cell 4A LDS, and Cell 4B LDS.
4.3.6 Trip Blank Evaluation
All trip blank results were reviewed to identify any blank contamination. Trip blank evaluations
are provided in Tab E. All trip blank results associated with the samples were less than the
reporting limit for the VOCs.
4.3. 7 QA/QC Evaluation for Sample Duplicates
Section 9.1.4 a) of the QAP states that the relative percent difference (the "RPD") will be
calculated for the comparison of duplicate and original field samples. The QAP acceptance limits
for RPDs between the duplicate and original field sample is less than or equal to 20% unless the
measured results are less than 5 times the required detection limit. This standard is based on the
EPA Contract Laboratory Program National Functional Guidelines for Inorganic Data Review,
February 1994, 9240.1-05-01 as cited in the QAP. The RPDs are calculated for all duplicate pairs
for all analytes regardless of whether or not the reported concentrations are greater than 5 times
the required detection limits; however, data will be considered noncompliant only when the results
are greater than 5 times the required detection limit and the RPD is greater than 20%. RPDs are
also only calculated when both the sample and the duplicate report a detection for any given
analyte. If only one of the pair reports a detection the RPD cannot be calculated. The additional
duplicate information is provided for information purposes.
All duplicate results were within 20% RPD except for pH, arsenic, beryllium, cobalt, copper,
manganese, molybdenum, selenium, uranium, and vanadium in the duplicate pair Cell 1/Cell 65.
The pH results were greater than 20% RPD, however, the sample and duplicate results were not
greater than 5 times the RL and as such are acceptable. Per the approved QAP, and in response to
requests from DWMRC, a separate corrective action for duplicate RPDs outside of acceptance
8
limits has been developed. The revised procedure for duplicate results outside of acceptance limits
was implemented. The corrective actions that were taken in accordance with the revised procedure
are as follows: the QAM contacted the Analytical Laboratory and requested a review of the raw
data to assure that there were no transcription errors and the data were accurately reported. The
laboratory noted that the data were accurate and reported correctly. Reanalysis was not completed
as the RPDs above the limit are likely due to interferences caused by the matrix, as discussed
below. There is no effect on the usability of the data due to the duplicate results exceeding the
comparability criteria because the matrix of the sample solution caused the noncompliance.
Results of the RPD test are provided under Tab E. The radiologic duplicates are discussed in
Section 4.3.8 below.
4.3.8 Radiologic Counting Error
Section 9.14 of the QAP requires that all gross alpha analysis reported with an activity equal to or
greater than the Groundwater Compliance Limit (the "GWCL") (for the tailings system wastewater
samples the GWQS will be used), shall have a counting variance that is equal to or less than 20%
of the reported activity concentration. An error term may be greater than 20% of the reported
activity concentration when the sum of the activity concentration and error term is less than or
equal to the GWQS.
Results of routine radiologic sample QC are provided under Tab E. All tailings system wastewater
radiologic sample results, except for Cell 3, met the counting error requirement. The error term in
Cell 3 was greater than 20% caused by matrix interference due to the nature of the tailings solution.
Section 9.1.4 of the QAP also requires a comparability check between the sample and field
duplicate sample results utilizing the formula provided below:
The original and duplicate sample did not meet the duplicate comparability check specified in the
QAP for gross alpha. Results of the RPD test are provided under Tab E. Per the approved QAP,
and in response to requests from DWMRC, a separate corrective action for duplicate RPDs outside
of acceptance limits has been developed and is documented in the revised QAP. The revised
procedure for duplicate results outside of acceptance limits was implemented for the gross alpha
results in duplicate pair Cell 1/Cell 65. The corrective actions that were taken in accordance with
the revised procedure are as follows: the QA Manager contacted the Analytical Laboratory and
requested a review of the raw data to assure that there were no transcription errors and the data
were accurately reported. The laboratory noted that the data were accurate and reported correctly.
Reanalysis was not completed as the RPDs above the limit are likely due to interferences caused
by the matrix as discussed below.
The lack of comparability of the gross alpha results is indicative of a matrix interference and does
not affect the usability of the data. Matrix interference is most likely caused by high concentrations
of TDS and other constituents in the sample.

4.3.9 Laboratory Matrix QC Evaluation
Section 9.2 of the QAP requires that the laboratory's QA/QC Manager check the following items
in developing data reports: (1) sample preparation information is correct and complete, (2)
analysis information is correct and complete, (3) appropriate analytical laboratory procedures are
followed, (4) analytical results are correct and complete, (5) QC samples are within established
control limits, (6) blanks are within QC limits, (7) special sample preparation and analytical
requirements have been met, and (8) documentation is complete. In addition to other laboratory
checks described above, EFRI's QAM rechecks QC samples and blanks (items (5) and (6)) to
confirm that the percent recovery for spikes and the relative percent difference for spike duplicates
are within the method-specific required limits, or that the case narrative sufficiently explains any
deviation from these limits. Results of this quantitative check are provided under Tab E. All lab
QA/QC results from both EL and GEL met these requirements. There were QC results which did
not meet laboratory established acceptance limits, as identified in Tab E and described below.
A significant number of the tailings system wastewater samples had the RL raised for multiple
analytes due to matrix interference and/or sample dilution. RL evaluations are discussed in Section
4.3.5.
The check samples included at least the following: a method blank, a laboratory control spike
("LCS"), a matrix spike ("MS") and a matrix spike duplicate ("MSD"), or the equivalent, where
applicable.
All qualifiers, and the corresponding explanations reported in the QA/QC Summary Reports for
any of the check samples for any of the analytical methods were reviewed by the QAM.
The QAP Section 8.1.2 requires that a MS/MSD pair be analyzed with each analytical batch,
depending upon the analytical method requirements and/or method limitations. The QAP does not
specify acceptance limits for the MS/MSD pair, and the QAP does not specify that the MS/MSD
pair be prepared on EFRI samples only. Acceptance limits for MS/MSDs are set by the
laboratories. The review of the information provided by the laboratories in the data packages
verified that the QAP requirement to analyze a MS/MSD pair with each analytical batch was met.
While the QAP does not require it, the recoveries were reviewed for compliance with the
laboratory established acceptance limits. The QAP does not require this level of review, and the
results of this review are provided for information only.
The information from the Laboratory QA/QC Summary Reports indicates that the MS/MSDs
recoveries and the associated RPDs for the samples were within acceptable laboratory limits except
as indicated in Tab E. The data recoveries and RPDs which are outside the laboratory established
acceptance limits do not affect the quality or usability of the data because the recoveries and RPDs
above or below the acceptance limits are indicative of matrix interference most likely caused by
other constituents in the samples. Matrix interferences are applicable to the individual sample
results only. The requirement in the QAP to analyze a MS/MSD pair with each analytical batch
was met and as such the data are compliant with the QAP.
10
The QAP specifies that surrogate compounds shall be employed for all organic analyses, but the
QAP does not specify acceptance limits for surrogate recoveries. The analytical data associated
with the routine quarterly sampling met the requirement specified in the QAP. The information
from the Laboratory QA/QC Summary Reports indicates that the surrogate recoveries for the
samples were within acceptable laboratory limits for the surrogate compounds. The requirement
in the QAP to analyze surrogate compounds was met and the data are compliant with the QAP.
Furthermore, there are no QAP requirements for surrogate recoveries.
The information from the Laboratory QA/QC Summary Reports indicates that the LCS/LCSD
recoveries for the samples were within acceptable laboratory limits for all LCS/LCSD compounds
except as noted in Tab E. The compounds noted with LCS/LCSD recoveries outside of acceptance
limits are noted for low recovery and the surrogate recoveries associated with the LCS/LCSD
indicate that the analytical system was operating within acceptable limits and the data are
acceptable as reported and there is no effect on the usability of the data.
The QAP, Section 8.1.2 requires that each analytical batch shall be accompanied by a method
blank. The analytical batches routinely contain a blank, which is a blank sample made and carried
through all analytical steps. For the Mill samples, a method blank was prepared for the analytical
methods. Per the approved QAP, contamination detected in analysis of method blanks will be
used to evaluate any analytical laboratory contamination of environmental samples. The QAP
states that non-conformance conditions will exist when contaminant levels in the samples(s) are
not an order of magnitude greater than the blank result. Molybdenum, tin, uranium, and copper
were reported the method blank from EL. The QAP criteria were not met for tin in the Cell 2
slimes, Cell 4A LDS, and Cell 3 samples because the method blank detections were not less than
an order of magnitude of the sample results. The method blank detection indicates false positive
results or high biased for tin in the samples, however, since the Cell 2 slimes, Cell 4A LDS, and
Cell 3 were all nondetect there is no effect on the sample results. No specific corrective actions
are specified in the QAP. The QAP requirement to analyze a method blank with each batch and
evaluate the results has been completed as required. Method blank results are included in Tab E.
The EL data packages noted low recoveries in the initial calibration verification ("ICV") samples
for manganese, cobalt and thallium. Low recoveries in the ICV sample could indicate a low bias
to the sample results. The low ICV recoveries do not affect the quality or usability of the data
because the results of this sampling provide an "inventory" of cell composition and are not used
for comparison to regulatory limits.
5.0 HISTORIC DATA
The historic analytical data for the tailings system wastewater sampling program are included in
Tab D. In addition, the average concentrations for Cell 3, compiled in the DWMRC GWDP,
Statement of Basis for a Uranium Mining Facility at White Mesa, South of Blanding, Utah, dated
December 1, 2004 are included in Tab D.

6.0 SUMMARY AND CONCLUSIONS
6.1 Cell 1
Cell 1 solutions were acidic in nature with a laboratory pH of 0.4. As expected, the solutions
contained gross alpha, major ions, metals, and VOCs. SVOCs, except pyridine, were not detected.
Regarding major ions, chloride, fluoride, magnesium, ammonia, potassium, sodium and sulfate
were one or more orders of magnitude greater in concentration than the other major ions. Metals
exhibiting the greatest concentration by at least one order of magnitude higher than the other metals
analyzed included arsenic, beryllium, cadmium, chromium, cobalt, copper, iron, lead, manganese,
molybdenum, nickel, selenium, silver, thallium, tin, uranium, vanadium and zinc. A decrease was
noted in the gross alpha concentration in the September 2021 sample. The variable gross alpha
results are being caused by matrix interference due to the nature of the tailings solution and are not
representative of gross alpha from radium concentrations in the solution. This is evidenced by the
results of the voluntary additional analyses. The results of the voluntary analyses are shown in Tab
D.
The majority of the concentrations reported in the 2021 sample remained within historic ranges.
Nitrate, pH mercury, fluoride, sodium, sulfate, TDS, arsenic, beryllium, lead, manganese,
selenium, thallium and vanadium had reported concentration outside of the historic ranges. Both
increases and decreases were noted. The concentrations which fall outside of the historic ranges
are due to effects from the severe local drought, routine sampling and analytical error, and matrix
interferences during the analyses caused by the inherent composition of the fluids. It is important
to note that not all constituents present in the tailings fluids will exhibit the same behavior as a
result of concentration of the tailings fluids and any increases or decreases in constituent results
will not be linear. The individual constituent results are greatly affected by the matrix of the
tailings fluids and each constituent will behave differently based on the matrix interactions and the
differing solubility properties of the constituent.
Comparison of Cell 1 fluids to those of Cells 4A, and 4B reveals that Cell 1 1s similar in
concentration ratios to the fluids in Cells 4A and 4B.
6.2 Cell 3
Cell 3 solutions were basic in nature, with a laboratory pH of 10. As expected, the solutions
contained major ions, metals, and VOCs (acetone only). SVOCs were not detected. Regarding
major ions, carbonate and bicarbonate, chloride, ammonia, sodium and sulfate were generally one
or more orders of magnitude greater in concentration than the other major ions. Metals exhibiting
the greatest concentration by at least one order of magnitude greater than the other metals analyzed
included arsenic, copper, iron, molybdenum, selenium, uranium, vanadium and zinc. A decrease
in the gross alpha and many metals and ions concentrations was noted in the September 2021
sample while an increase was noted in pH, carbonate, bicarbonate and molybdenum. The reason
for the changes in many constituent concentrations was due to nature of the process solutions that
flowed into Cell 3.
12
The analyte concentrations reported in the 2021 sample decreased overall relative to the 2019
results. The changes in concentrations are likely due to the pH change noted in 2021. The pH
change is the result of the process solutions that were added in 2021. It is important to note that
not all constituents present in the tailings fluids will exhibit the same behavior as a result of
concentration of the tailings fluids and any increases or decreases in constituent results will not be
linear. The individual constituent results are greatly affected by the matrix of the tailings fluids
and each constituent will behave differently based on the matrix interactions and the differing
solubility properties of the constituent.
6.3 Cell 4A
Cell 4A solutions were acidic in nature, with a laboratory pH of 2.2. As expected, the solutions
contained gross alpha, major ions, metals. VOCs and SVOCs were not detected. Cell 4A fluid
exhibited the highest major ion concentrations for chloride, fluoride, magnesium, ammonia,
potassium, sodium and sulfate. The metals arsenic, cadmium, chromium, cobalt, copper, iron, lead,
manganese, molybdenum, nickel, selenium, uranium, vanadium and zinc were one or more orders
of magnitude greater than the other metals analyzed. An increase in the gross alpha concentration
of the 2021 sample was noted. The variable gross alpha results are being caused by matrix
interference due to the nature of the tailings solution and are not representative of gross alpha from
radium concentrations in the solution. This is evidenced by the results of the voluntary additional
analyses which are shown in Tab D.
Overall, the concentrations reported in the 2021 sample remained approximately the same as the
2020 sample. Chloride, fluoride nitrate, sodium, and TDS reported concentration slightly above
the historic ranges. Concentration changes noted are within the analytical accuracy of the methods
used for analysis. It is important to note that not all constituents present in the tailings fluids will
exhibit the same behavior as a result of concentration of the tailings fluids and the increases in
constituent results will not be linear. The individual constituent results are greatly affected by the
matrix of the tailings fluids and each constituent will behave differently based on the matrix
interactions and the differing solubility properties of the constituent.
Comparison of Cell 4A fluids to those of Cells 1 and 4B reveals that Cell 4A is similar in
concentration ratios to the fluids in Cells 1 and 4B.
6.4 Cell 4B
Cell 4B solutions were acidic in nature, with a laboratory pH of 1.2. As expected, the solutions
contained gross alpha, major ions, metals, and VOCs. SVOCs, except pyridine were not detected.
Cell 4B fluid exhibited the highest major ion concentrations for chloride, fluoride, magnesium,
ammonia, potassium, sodium and sulfate. The metals arsenic, beryllium, cadmium, chromium,
cobalt, copper, iron, lead, manganese, molybdenum, nickel, selenium, thallium, uranium,
vanadium and zinc were one or more orders of magnitude greater than the other metals analyzed.
An increase in the gross alpha concentration of the 2021 sample was noted. The variable gross
alpha results are being caused by matrix interference due to the nature of the tailings solution and
are not representative of gross alpha from radium concentrations in the solution. This is evidenced
by the results of the voluntary additional analyses which are shown in Tab D.
13
The concentrations reported in the 2021 sample are above previous results due to the cell liquid
pool shrinking due to reprocessing and severe drought conditions which concentrated the
constituents. It is important to note that not all constituents present in the tailings fluids will exhibit
the same behavior as a result of concentration of the tailings fluids and the increases in constituent
results will not be linear. The individual constituent results are greatly affected by the matrix of
the tailings fluids and each constituent will behave differently based on the matrix interactions and
the differing solubility properties of the constituent.
Comparison of Cell 4B fluids to those of Cells 1 and 4A reveals that Cell 4B is similar in
concentration ratios to the fluids in Cells 1 and 4A.
6.5 Cell 2 Slimes Drain
Cell 2 Slimes drain fluid was acidic in nature, with a laboratory pH of 3.0. As expected, the
solutions contained gross alpha, major ions, metals, and VOCs. Two SVOCs were detected. Major
ions that were highest in concentration by one or more orders of magnitude included chloride,
magnesium, ammonia, sodium and sulfate. For metals, arsenic, cadmium, chromium, cobalt,
copper, iron, manganese, molybdenum, nickel, thallium, uranium, vanadium and zinc were at least
one order of magnitude greater in concentration than other metals analyzed. The 2021 gross alpha
concentration remained similar to the 2020 sample result. The gross alpha result remains in the
same order of magnitude of the historic data. It is important to note that gross alpha results affected
by matrix interference due to the nature of the tailings solution and are not representative of gross
alpha from radium concentrations in the solution. This is evidenced by the results of the voluntary
additional analyses which are shown in Tab D.
The concentrations reported in the 2021 sample remained within historic ranges. Concentration
changes noted are within the analytical accuracy of the methods used for analysis.
6.6 Cells 3, 4A and 4B Slimes Drain
In accordance with the Permit, the slimes drains for Cell 3, 4A and 4B are not required to be
sampled until dewatering operations have begun. Cell 1 was designed to be used solely as an
evaporation pond and does not have a slimes drain.
6.7 Cells 1, 2, and 3 Leak Detection Systems
Consistent with the Permit, the Cells 1, 2, and 3 LDSs were not sampled during the 2021 sampling
event. The Cells 1, 2, and 3 LDSs were dry.
6.8 Cell 4A Leak Detection System
Cell 4A LDS solutions were acidic in nature, with a laboratory pH of 2.4. As expected, the
solutions contained gross alpha, major ions, metals and VOCs. No SVOCs were detected. Cell
4A LDS fluid exhibited the highest major ion concentrations for chloride, fluoride, magnesium,
ammonia, sodium, and sulfate. The metals arsenic, cadmium, chromium, cobalt, copper, iron, lead,
14
manganese, molybdenum, nickel, selenium, uranium, vanadium, and zinc were one or more orders
of magnitude greater than the other metals analyzed. A slight increase in the gross alpha
concentration, compared to the 2020 sample was noted. The variable gross alpha results are being
caused by matrix interference due to the nature of the tailings solution and are not representative
of gross alpha from radium concentrations in the solution. This is evidenced by the results of the
voluntary additional analyses which are shown in Tab D.
The majority of the concentrations reported in the 2021 sample remained within historic ranges.
Fluoride, cobalt, acetone and methyl ethyl ketone had reported concentration above the historic
ranges. The concentrations which fall outside of the historic ranges are due to effects from the
severe local drought, routine sampling and analytical error, and matrix interferences during the
analyses caused by the inherent composition of the fluids.
6.9 Cell 4B Leak Detection System
Cell 4B LDS solutions were acidic in nature, with a laboratory pH of 2.0. As expected, the
solutions contained gross alpha, major ions, and metals. No VOCs were detected. Two SVOCs
was detected. Cell 4B LDS fluid exhibited the highest major ion concentrations for chloride,
fluoride, magnesium, ammonia, potassium, sodium, and sulfate. The metals arsenic, beryllium,
cadmium, chromium, cobalt, copper, iron, lead, manganese, molybdenum, nickel, selenium,
uranium, vanadium and zinc were one or more orders of magnitude greater than the other metals
analyzed. An increase in the gross alpha concentration was noted in the 2021 sample. The variable
gross alpha results are being caused by matrix interference due to the nature of the tailings solution
and are not representative of gross alpha from radium concentrations in the solution. This is
evidenced by the results of the voluntary additional analyses which are shown in Tab D.
The majority of the concentrations reported in the 2021 sample remained within historic ranges.
Fluoride, nitrate, cobalt, lead, molybdenum and uranium had reported concentration outside of the
historic ranges. Both increases and decreases were noted. The concentrations which fall outside
of the historic ranges are due to changes in the Cell 4B solutions caused by effects from the severe
local drought, routine sampling and analytical error, and matrix interferences during the analyses
caused by the inherent composition of the fluids.
6.10 Summary and Conclusions of Analytical Results
The metals arsenic, cadmium, chromium, cobalt, copper, iron, manganese, molybdenum, nickel,
selenium, uranium, vanadium and zinc were generally present in greatest concentration for all
samples. For major ions, chloride, fluoride, magnesium, ammonia, sodium, and sulfate were
predominant. Both increases and decreases were noted for several metals and major anions.
Concentrations are variable and are driven by Mill operations. EFRI conducted additional
voluntary analyses (not required by the GWDP) in order to further characterize the radiological
and physical properties of the tailings solution, as discussed Section 3.1 above. The results of the
additional voluntary analyses for radium-226, thorium-228, thorium-230, thorium-232, uranium-
233/234, uranium-235/236, uranium-238, and specific gravity show that the variability in gross
alpha results are being caused by matrix interference due to the nature of the tailings solution and
are not representative of gross alpha from radium concentrations in the solution. EFRI may or may
15
not choose to continue these additional analyses in the future. The changes in concentrations of
metals and major ions are reflective of Mill operations and are driven by the addition/movement
of fluids during periods of operation. The individual constituent results are greatly affected by the
matrix of the tailings fluids and each constituent will behave differently based on the matrix
interactions and the differing solubility properties of the constituent. Overall, the results of the
2021 tailings solutions are within historic, expected ranges except as noted above.

CASE NARRATIVE
This report has been revised to include lower reporting limits for lead and thallium for sample Cell 1 (C21090172-001),
thallium for sample Cell 4A (C21090172-003), thallium for sample Cell 4A LOS (C21090172-004), thallium for sample Cell 8
(C21090172-008).
This revised report replaces any previously issued report on 10/29/2021 in its entirety.
Revised 10/29/2021
This report has been revised to include Total Dissolved Solids for samples Cell 1 (C21090172-001), Cell 4B (C21090172-
005), and Cell 65 (C21090172-007) as per telephone request from Kathy Weinel on 10/29/2021. Please see results pages
for more information.
Tests associated with analyst identified as "etad" were subcontracted to Eurofins Test America, 4955 Yarrow St, Arvada, CO
80002, TEL [phone]. Please see attached data packet for details.
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4°C (±2°C)
Temperature of samples received may not be considered properly preserved by accepted standards. Samples that are hand
delivered immediately after collection shall be considered acceptable if there is evidence that the chilling process has begun.
GROSS ALPHA ANALYSIS
Method 900.0 for gross alpha and gross beta is intended as a drinking water method for low TDS waters. Data provided by
this method for non potable waters should be viewed as inconsistent.
RADON IN AIR ANALYSIS
The desired exposure time is 48 hours (2 days). The time delay in returning the canister to the laboratory for processing
should be as short as possible to avoid excessive decay. Maximum recommended delay between end of exposure to
beginning of counting should not exceed 8 days.
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.

Standard Reporting Procedures:
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.
Contact and Corrective Action Comments:
Dissolved Metals/Hardness were filtered and preserved to pH <2 with 2 ml of nitric acid per 250 ml in the laboratory.
According to 40CFR 136, samples for Dissolved Metals should be filtered and preserved within 15 minutes of collection.

Data Summary:
All sample data provided in this report met the acceptance criteria specified in the analytical methods and
procedures for initial calibration, continuing calibration, instrument controls and process controls where
applicable, with the following exceptions.
Quality Control (OC) Information
Laboratory Control Sample Duplicate (LCSD)
An LCSD was used in place of matrix QC due to limited sample volume.
LCS/LCSD Relative Percent Difference (RPD) Statement
The RPD values between the LCS and LCSD (See Below) did not meet the acceptance limits for one or more
analytes. Since the individual LCS and LCSD recoveries for these analytes were within the established
acceptance criteria, the failures did not adversely impact the reported data.

Technical Information
Sample Re-extraction/Re-analysis
Samples 554861001 (Cell I), 554861005 (Cell 4B) and 554861007 (Cell 65) contained detects of Pyridine just
above the LOQ. The daily CCV passed acceptance criteria for Pyridine; however, the ICY was biased high for
this analyte. The samples were re-extracted out of holding and analyzed on an instrument with passing ICY and
CCV. The Pyridine results were confirmed. The initial data results were reported.
Miscellaneous Information
Additional Comments
Diphenylamine Statement
Diphenylamine has now superseded N-Nitroso-diphenylamine as a CCC in EPA Method 8270C. Previous
versions of EPA Method 8270 (prior to 8270C) listed N-Nitroso-diphenylamine as a CCC. However, as stated in
EPA Method 8270C, Revision 3, December, 1996, Section 1.4.5, "N-Nitroso-diphenylamine decomposes in the
gas chromatographic inlet and cannot be separated from Diphenylamine." Studies of these two compounds at
GEL, both independent of each other and together, show that they not only coelute, but also have similar mass
spectra. The GEL Mobile Lab will report N-Nitroso-diphenylamine and Diphenylamine as
N-Nitroso-diphenylamine on all reports and forms.
Certification Statement
Where the analytical method has been performed under NELAP certification, the analysis has met all of the
requirements of the NELAC standard unless otherwise noted in the analytical case narrative.
