2012 ANNUAL TAILINGS CELLS WASTEWATER SAMPLING REPORT
1.0 INTRODUCTION
This is the 2012 Annual Tailings Cells 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 Tailings Cells Leak Detection Systems and
Slimes Drains, Revision: 2.1, dated July 30,2012 (the "Sampling Plan").
Tailings and slimes drain sampling is required under the Sampling Plan and Part I.E.l 0 of the
Permit to be conducted on an annual basis in August of each year for the solutions in tailings
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 Cell4A and4B 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
State of Utah Division of Radiation Control ("DRC") with the Mill's Third Quarter Groundwater
Monitoring Report due December 1, of each year.
1.1 Sampling Plan Revisions
The Mill's Tailings and Slimes Drain Sampling and Analysis Program, Revision: 0, was revised
during the 2012 reporting period. The revisions were completed to address safety concerns for
sampling personnel and to address inconsistencies between the actual sampling techniques used
and the Revision 0 Sampling Plan. DRC approved Revision 2.1 of the Sampling Plan by letter
dated August 2, 2012, which was received by EFRI on August 6, 2012.
2.0 SAMPLING EVENTS AND SAMPLING METHODOLOGY
2.1 Sampling Events
Samples of solutions from tailings Cells 1, 3, 4A, and 4B, the Cell 2 slimes drain and the Cells
4A and 4B LDSs were collected on August 15, 2012. Upon receipt of the data, review of the
Semivolatile Organic Compounds ("SVOCs") data from Cell 1 indicated that the required
reporting limits ("RLS") were not achievable due to matrix difficulties. The Cell 1 SVOC
sample "solidified" during the extraction process prior to achieving the desired final volume, and
as a result, the reporting limits were raised. The extraction difficulty most likely resulted from
hyper-concentration of the tailings fluids over the summer when solution feed to Cell 1 ceased
temporarily during the repairs to the liner. EFRI notified DRC via telephone on September 5,
2012 of the raised RL and the likely reasons for the difficulty. DRC directed EFRI to collect an
additional SVOC sample from Cell 1 to attempt to address the raised RL. DRC noted that if the
resampling did not address the issue, no further sampling was required. This sampling event did
result in data ·with acceptable RLs, and no further sampling was conducted after October 22,
1
2012. EFRI collected an additional sample and duplicate for SVOC analysis from Cell 1 on
October 22, 2012.
In accordance with the Permit, DRC was notified of the August 15, 2012 sampling event and a
DRC representative was present for a part of the sampling. The DRC representative collected a
split aliquot of the Tailings Cell 4B sample. DRC personnel did not request or require
notification for resampling effort of the Ce111 SVOCs on October 22, 2012.
Maps showing the locations of the tailings and slimes drain and, when applicable, LDS sampling
locations are attached under Tab B. Tailings wastewater sampling required by the Permit is
discussed in the remainder of this section.
2.2.1 Tailings Wastewater Compliance Monitoring
Table 1, included in the Tables Tab, provides an overview of all tailings wastewater monitoring
samples collected during the current period and includes the sarnpling date, laboratory report
date, and the work order/lab set ID associated with the analytical data.
The Permit requires that the tailings wastewater samples be analyzed for the water quality
parameters listed in Table 2 of the Permit and SVOCs.
2 .. 2 Field Data
Attached under Tab A are copies of all of the field data sheets recorded in association with the
annual tailings wastewater monitoring program. Sampling dates are listed in Table 1.
2 .. 3 Sampling Methodology, Equipment and Decontamination Procedures
As noted in the DRC-approved Sampling Plan, Revision 2.1, dated July 30, 2012, 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 by
the analytical laboratory within 24 hours of receipt. 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 the 2011 field data, the tailings, LDS and slimes drain samples were at a
pH of 3.0 or less 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. The VOC sample aliquots were preserved in the field.
2.3.1 Tailings Cells ·
Tailings fluid samples were collected at the tailings cell sampling stations shown on the Figures
in Tab Busing a ladle as noted in the DRC-approved Sampling Plan, Section 3.1.2.
2
Disposable sample ladles were used during this sampling event and as such rinsate samples were
not required.
2.3.2 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
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, the Cells are still active and the slimes drains will not be
pumped (and/or sampled) until dewatering operations have commenced.
The Cell2 slimes drain, shown on the Figures in Tab B, was sampled using a disposable bailer as
noted in the DRC-approved Sampling Plan, Section 3.1.3.
Due to the use of disposable bailer, a rinsate sample was not required.
2.3 .. 3 Cell 4A and Cell 4B Leak Detection Systems
The Cell 4A and 4B LDS samples were collected from the sampling stations shown on the
Figures in Tab B using a stainless steel bucket and disposable ladle as noted in the DRC-
approved Sampling Plan, Section 3.2.1.
2.3.4 Cells 1, 2, and 3 Leak Detection System
The Cells 1, 2, and 3 LDSs were not sampled during the 2012 sampling event because the
systems were dry.
2.4 Field QC Samples
The field Quality Control ("QC") samples generated during this sampling event included one
duplicate for the August 15, 2012 sampling event, one duplicate for the October 22, 2012 Cell 1
resampling event and one trip blank per shipment to each laboratory which received samples for
Volatile Organic Compounds (VOCs). The duplicate samples (Cell 65 and Cell 70) were
submitted blind to the analytical laboratory. As previously stated, no rinsate blanks were
collected during this sampling event as only disposable equipment was used for sample
collection.
2.5 Laboratory Results
All analytical results were provided by one of the Mill's two contract analytical laboratories,
Energy Laboratories ("EL") or America West Analytical Laboratories ("A W AL").
The laboratories utilized during this investigation were certified under the Environmental Lab
Certification Program administered by the UDEQ Bureau of Lab Improvement for the analyses
they completed.
3
The analytical data as well as the laboratory Quality Assurance ("QA")/QC summaries are
included under Tab C.
3.0 QUALITY ASSURANCE AND DATA EVALUATION
The Permit requires that the annual tailings 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 this requirement, the data validation completed for the tailings 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 QA Manager performed a
QAIQC 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 collected and analyzed is provided in Section 3.3.1. Discussion of adherence to the
Sampling Plan is provided in Section 3.1. Analytical completeness review results are provided
in Section 3.2. The steps and tests applied to check laboratory data QA/QC are discussed in
Sections 3.3.1 through 3.3.9 below.
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 and Analytical
Request Record 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 3.3, below.
3el Adherence to Sampling Plan and Permit Requirements
On a review of adherence by Mill personnel to the Permit, the QA Manager observed that
QA/QC requirements established in the Permit, the QAP, and the Sampling Plan were being
adhered to and that the requirements were implemented as required.
3.2 Analyte Completeness Review
All analyses required by the Permit Table 2 were completed. In addition, all tailings wastewater
samples were analyzed for SVOCs as required by the Permit.
3e3 Data Validation
The QAP and the Permit identify the data validation steps and data quality control checks
required for the tailings wastewater monitoring program. Consistent with these requirements, the
Q.A .. 1\1anager performed the following evaluations: a field data QNQC evaluation, a receipt
4
temperature check, a holding time check, an analytical method check, a reporting limit check, a
trip blank 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.
3.3.1 Field Data QA/QC Evaluation
The QA Manager 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.
3.3a2 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 received and analyzed within the
required holding time.
3.3.3 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.
3 .. 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. Analytical method check results are provided in Tab E.
3.3.5 Reporting Limit Evaluation
All analytical method reporting limits reported by both laboratories were checked against the
reporting limits specified in the Permit. Reporting limit evaluations are provided in Tab E. All
anal ytes were measured and reported to or reported below the required reporting limits except
the Cell 1 SVOCs as noted in Section 2. 1. The Cell 1 tailings fluid sample was recollected and
the reanalyzed sample met the RL requirements of the Permit. In addition, several sets of sample
results had the reporting limit raised for at least one analyte due to sample dilution. In all cases
but one, the reported value for the analyte was. higher than the increased detection limit. The one
case in which the reported value for the analyte was not higher than the increased reporting limit
involved the tetrahydrofuran ("THF") results for the Cell 1 tailings fluid. The THF result in Cell
1 tailings fluid had a positive detection reported as 2.90 ug/L due to sample dilutions which were
necessary due to interferences from high concentrations of other analytes (most likely metals) in
the sample. The permit requires a reporting limit less than the Groundwater Quality Standard
("GWQS") of 46.0 ug/L. The RL was 10.0 ug/L which is below the GWQS; however, the
5
positive result was less than 10 ug/L. The laboratory applied a "J" flag to the positive results
indicating that the positive detection is estimated. The RL requirements in the Permit were met
and the THF data in Cell 1 tailings fluid are acceptable and usable. No corrective action is
required as the Permit required RL was met and there are no requirements in the permit that the
data be reported above the RL.
3o3.6 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 reporting
limit for all VOCs.
3.3e 7 QA/QC Evaluation for Sample Duplicates
Section 9.1.4 a) of the QAP states that RPDs will be calculated for the comparison of duplicate
and original field samples. The QAP acceptance limits for RPDs between the ~uplicate 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 a 20% RPD except for mercury and gross alpha in the duplicate
pair Cell 2 slimes drain/Cell 65. These mercury results are not greater than 5 times the required
reporting limit and the RPD is greater than 20 percent (24% ). Both of the mercury sample
results reported for Cell 2 slimes drain/Cell 65 were not five times greater than the reporting
limit of 0.5 ug/L and as such the deviation from the 20% RPD requirement is acceptable.
Results of the RPD test are provided under Tab E. The radiologic duplicates are discussed in
Section 3.3.8 below.
3 .. 3.8 Radiologies Counting Error
Section 9.14 of the QAP requires that all gross alpha analysis reported with an activity equal to
or greater than the GWCL (for the tailings 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 wastewater
radiologic sample results met the counting error requirement.
6
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 duplicate sample did not meet the duplicate comparability check specified in the
QAP. Results of the RPD test are provided under Tab E. Per QAP, Revision 7.2, and in response
to requests from UDEQ, 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 Slimes #2/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. In addition, reanalysis was completed as the samples were within the holding time.
The reanalysis results also exceeded the comparability check specified above.
The lack of comparability of both duplicate sets is indicative of a matrix interference. There is
no affect on the usability of the data due to the gross alpha duplicate results exceeding the
comparability criteria because the nature of the sample solution caused the noncompliance.
3.3.9 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, DUSA's QA Manager 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 A W AL 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 wastewater samples had the reporting limit raised for
multiple analytes due to matrix interference and/or sample dilution. RL evaluations are
discussed in Section 3.3.5.
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 C'MSD''); or the equivalent, where
applicable. It should be noted that:
7
• Laboratory fortified blanks are equivalent to LCSs.
• Laboratory reagent blanks are equivalent to method blanks.
• Post digestion spikes are equivalent to MSs.
• Post digestion spike duplicates are equivalent to MSDs.
• For method E900.1, used to determine gross alpha, a sample duplicate was used instead
ofaMSD.
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 QA Manager.
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 all tailings wastewater samples were within acceptable
laboratory limits for all regulated compounds except as indicated in Tab E. The recoveries and
RPDs which are outside of the laboratory established acceptance limits do not affect the quality
or usability of the data because the recoveries and RPDs outside of the acceptance limits are
indicative of matrix interference. The SVOC and several inorganic analytes were problematic
due to the natural pH of the samples as collected. The recoveries outside of acceptance limits
reported in these analyses were due to a matrix interference caused by high levels of metals and
other inorganic constituents. The QAP requirement to analyze a MS/MSD pair with each
analytical batch was met and as such the data are compliant with the QAP.
Seventeen metals MS/MSD recoveries were not calculated because the analyte level in the
natural sample was 4 times greater than the spike level added by the laboratory. It is not possible
to calculate the MS/MSD recovery when the sample results are significantly higher than the
spike amount added. In effect, the sample results mask the spike results and the calculations are
not possible. There is no effect on the quality or usability of the data.
· 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 all
tailings wastewater samples were within acceptable laboratory limits for all surrogate
compounds except as indicated in Tab E. There were two surrogate compounds in the VOCs
8
that were above the acceptance limit specified by the laboratory. The results were above the
upper limit or had a high recovery, indicating a high bias to the sample results. A high bias
means that the reported result for this analyte will tend to be higher than it actually is. There is
no affect on the quality or usability of the data.
There are six surrogate recoveries outside of acceptance limits for the SVOC analyses. In all
instances the surrogate recoveries outside of acceptance limits were the result of a matrix
interference. A matrix interference resulted in the the surrogate compounds being outside of the
acceptance limits noted in Tab E. There are other surrogate compounds used for SVOC analyses
which were all within acceptance limits. As such there is no effect on the quality or usability of
the data. Since surrogate compounds were added to all of the organic analyses as required by the
QAP, the data are compliant with the QAP requirements.
The QAP Section 8.1.2 requires that each analytical batch shall be accompanied by a reagent
blank. Contamination detected in analysis of reagent blanks (method blank) will be used to
evaluate any analytical laboratory contamination of environmental samples. The QAP criteria
for method blanks states that nonconformance will exist when blanks are within an order of
magnitude of the sample results. Bicarbonate and sulfate were reported in the method blanks
from EL. Method blank results are included in Tab E. In all cases the samples were nondetect
for bicarbonate. The QAP criteria were not met because the method blank was within an order of
magnitude of the sample results; however, since the sample results were all nondetect there is no
effect on the quality and usability of the bicarbonate sample data. In all cases the sample results
for sulfate were more than an order of magnitude greater than the method blanks and the QAP
criteria were met. The QAP requirement to analyze a method blank with each batch and evaluate
the results has been completed as required.
4&0 HISTORIC DATA
The historic analytical data for the tailings wastewater sampling program are included in Tab D.
In addition, the minimum and maximum concentrations compiled in the Utah Division of
Radiation Control Groundwater Quality Discharge Permit, Statement of Basis for a Uranium
Mining Facility at White Mesa, South of Blanding, Utah, dated December 1, 2004 are included
in Tab D.
5.0 SUMMARY AND CONCLUSIONS
5.1 Celll
Cell 1 solutions were acidic in nature with a laboratory pH of 1.9. As expected, the solutions
contained high concentrations of metals and limited VOCs. SVOCs were not detected in the
October 22, 2012 sample. Regarding major ions; chloride, magnesium, ammonia, potassium,
sodium and sulfate were one to three 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, cadmium, chromium, cobalt, copper,
iron, lead, manganese, molybdenum, nickel, selenium, silver, uranium, vanadium and zinc.
9
Regarding VOCs, acetone was detected at approximately 3.25 times less than the 2010 sample
result. Acetone, chloroform, methylethyl ketone ("MEK"), chloromethane, methylene chloride
and naphthalene increased from the 2011 sample result. THF was detected at a concentration
lower than the previously reported RLs. When comparing these data to prior samplings, metals
were present in similar concentration ratios to previous sample results. Overall, the
concentrations reported in the 2012 sample increased from the 2011 sample most likely because
solutions were not added to the cell during the period of the liner repairs which were conducted
as weather permitted from late summer 2010 to June 2012. The liner repairs minimized the
fluids placed in tailings Cell 1, which allowed evaporation and concentration of the inorganic
constituents present in the tailings fluids.
5.2 Cell3
Cell 3 solutions were acidic in nature, with a laboratory pH of 2.4. As expected, the solutions
contained high concentrations of metals and limited VOCs. SVOCs were not detected.
Regarding major ions, chloride, fluoride, magnesium, ammonia, potassium, sodium and sulfate
were generally one to two 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 chromium, cobalt, copper, iron, manganese, nickel, uranium,
vanadium and zinc. With respect to VOCs, acetone, chloroform, and chloromethane, were
detected. All of the VOC concentrations decreased from 2011. When comparing these data to
prior samplings, metals were present in similar concentration ratios to previous sample results.
Overall, the concentrations reported in the 2012 sample increased from the 2011 sample most
likely due to the fact that Cell 3 is no longer used for the disposal of fluids in preparation for
eventual closure. The lack of fluids placed in tailings Cell 3 allowed evaporation and
concentration of the inorganic constituents present in the remaining fluids present.
5 .. 3 Cell4A
Cell 4A solutions were acidic in nature, with a laboratory pH of 1.2. As expected, the solutions
contained high concentrations of metals and limited VOCs. SVOCs were not detected. As was
the case for Cells 1 and 3, Cell 4A fluid exhibited the highest major ion concentrations for
chloride,. magnesium, ammonia, sodium and sulfate. For metals, arsenic, cobalt, copper, iron,
lead, manganese, molybdenum, nickel, uranium, vanadium and zinc were one or more orders of
magnitude greater than the other metals analyzed. Comparison of Cell4A fluids to those of Cells
1 and 3 reveals that Cell 4A is similar in composition and concentration ratios to the fluids in
both Cell 1 and Cell 3. VOC presence was limited, with the only measurable compounds being
acetone and THF. Overall, the concentrations reported in the 2012 sample remained the same as
2011 or decreased from the 2011 sample.
5 .. 4 Cell4B
Cell4B solutions were acidic in nature, with a laboratory pH of 1.5. As expected, the solutions
contained high concentrations of metals, limited VOCs and, with the exception of Bis (2-
ethylhexyl) phthalate, SVOCs were not detected. Bis (2-ethylhexyl) phthalate is a commonly
10
used plasticizer and may be present in sampling equipment (gloves, tubing). As was the case for
Cells 1 and 3, and Cell 4A, Cell 4B fluid exhibited the highest major ion concentrations for
chloride, magnesium, ammonia, potassium, sodium and sulfate. For metals, arsenic, cobalt,
copper, iron, lead, manganese, molybdenum, nickel, uranium, vanadium and zinc were one or
more orders of magnitude greater than the other metals analyzed. Comparison of Cell 4B fluids
to those of Cells 1, 3 and 4A reveals that Cell 4B is similar in composition and concentration
ratios to the fluids in Cells 1, 3 and 4A. VOC presence was limited, with the only measurable
compounds being acetone, chloroform, chloromethane, and THF. Overall, the concentrations
reported in the 2012 sample remained the same as 2011 sample.
5e5 Cell2 Slimes Drain
Cell 2 Slimes drain fluid was acidic in nature, with a laboratory pH of 3.0. As expected, the
solutions contained high concentrations of metals, and limited VOCs. SVOCs were not detected.
Major ions which were highest in concentration by one or more orders of magnitude included
chloride, magnesium, ammonia, sodium and sulfate. For metals, arsenic, cobalt, copper, iron,
manganese, nickel, uranium, vanadium and zinc were at least one order of magnitude greater in
concentration than other metals analyzed. VOCs were limited to low concentrations of acetone,
chloroform, chloromethane, MEK, naphthalene, THF, toluene, and xylenes. Overall, the
concentrations reported in the 2012 sample remained approximately the same as the 2011
sample. Minor concentration changes were noted, which are· within the analytical accuracy of
the methods used for analysis.
5.6 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 is an evaporation pond and does not
have a slimes drain.
5.7 Cell 2 Leak Detection System
The Cell 2 LDS was not sampled during the 2012 sampling event the Cell 2 LDS is now dry and
covered to prevent precipitation inflow.
5.8 Cells 1 and 3 Leak Detection System
The Cells 1 and 3 leak detection systems were not sampled during the 2012 sampling event
because the systems were dry.
5 .. 9 Cell 4A Leak Detection System
Fluids in the Cell 4A leak detection system were acidic in nature with a lab pH of 2.1. As
expected, the solutions contained high concentrations of metals, limited VOCs and, with the
exception of Bis (2-ethylhexyl) phthalate, SVOCs were not detected. Bis (2-ethylhexyl)
phthalate is a commonly used plasticizer and may be present in sampling equipment (gloves,
11
tubing). The major ions which exhibited the greatest concentrations included chloride,
magnesium, ammonia, sodium and sulfate. For metals, arsenic, cobalt, copper, iron, manganese,
molybdenum, nickel, uranium, vanadium and zinc were one or more orders of magnitude greater
in concentration than the other metals analyzed. The VOC's acetone, chloromethane, chloroform,
MEK, naphthalene and THF were measured at low concentration. Overall, the concentrations
reported in the 2012 sample decreased from the 2011 sample. Increases were slight and within
the analytical accuracy of the methods used for analysis.
5.10 Cell 4B Leak Detection System
Fluids in the Cell 4B leak detection system were acidic in nature with a lab pH of 2.4. As
expected, the solutions contained high concentrations of metals, limited VOCs and, with the
exception of Bis (2-ethylhexyl) phthalate, SVOCs were not detected. Bis (2-ethylhexyl)
phthalate is a commonly used plasticizer and may be present in sampling equipment (gloves,
tubing). The major ions which exhibited the greatest concentrations included chloride,
magnesium, ammonia, potassium, sodium and sulfate. For metals, arsenic, cobalt, copper, iron,
manganese, molybdenum, nickel, uranium, vanadium and zinc were one or more orders of
magnitude greater in concentration than the other metals analyzed. The VOC's acetone,
chloromethane, chloroform, MEK, and THF were measured at low concentration. Overall, the
concentrations reported in the 2012 sample stayed the same or increased slightly from the 2011
sample. The increase is most likely due to increased usage during 2012.
Sell Summary and Conclusions of Analytical Results
The metals arsenic, cobalt, copper, iron, manganese, molybdenum, nickel, uranium, vanadium
and zinc were generally present in greatest concentration for all samples. For major ions,
chloride, magnesium, ammonia, potassium, sodium and sulfate were predominant. VOCs with
the greatest concentrations in tailings fluids were acetone, chloroform, MEK, THF and
chloromethane. With the exception of Bis (2-ethylhexyl) phthalate, SVOCs were not detected.
6.0 CORRECTIVE ACTION REPORT
No corrective action reports are required for the 2012 annual sampling event.
6el Assessment of Corrective Actions from Previous Period
No corrective action reports were required for the 2011 annual sampling event and as such there
is no assessment of previous actions necessary.

reporting limits for the semivolatile compounds ("SVOCs"). The sample and a duplicate were recollected and analyzed
for SVOCs only.
**Data package was originally submitted on October 12, 2012. A corrected data package was submitted on October 17,
2012.
***As noted in Section 3.3.8 of this report, the Cell2 Slimes Drain/Cell65 gross alpha sample was reanalyzed due to
poor duplicate comparability. TheEL-C12080790R2 data package listed above contains the results of the gross alpha
reanalysis.

REVISED/SUPPLEMENTAL REPORT
Revised Date: 10/17/12
Report Date: 10/12/12
CASE NARRATIVE
The attached analytical report has been revised from a previously submitted report due to the request by the client on
October 16, 2012 for the addition of dissolved tin on sample -001 through -008. The data presented here is from that
additional analysis.
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±20C)
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 Ell reflects the results for
seven individual Aroclors. When the results for all seven are ND (not detected), the sample meets EPA compliance criteria
for PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize
its branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

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.

REVISED/SUPPLEMENTAL REPORT (R2)
Revised Date: 11/27/12
Report Date: 1 0/12/12
CASE NARRATIVE
The attached analytical report has been revised from a previously submitted report due to the request by Kathy Weinel on
November 13, 2012 for the reanalysis of Gross Alpha on samples -007 and -008. The data presented here is from that
recheck analysis.
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.
SOIUSOLID SAMPLES
All samples reported on an as received basis unless otherwise indicated.
ATRAZINE, SIMAZINE AND PCB ANALYSIS
Data for PCBs, Atrazine and Simazine are reported from EPA 525.2. PCB data reported by Ell reflects the results for
seven individual Aroclors. When the results for all seven are NO (not detected), the sample meets EPA compliance criteria
for PCB monitoring.
SUBCONTRACTING ANALYSIS
Subcontracting of sample analyses to an outside laboratory may be required. If so, ENERGY LABORATORIES will utilize
its branch laboratories or qualified contract laboratories for this service. Any such laboratories will be indicated within the
Laboratory Analytical Report.

RE: Annual Tailings
Dear J o Ann Tischler: Lab Set ID: 1208302
American West Analytical Laboratories received 9 sample(s) on 8/17/2012 for the
analyses presented in the following report.
American West Analytical Laboratories (A WAL) is accredited by The National
Environmental Laboratory Association Conference (NELAC) Institute in Utah and Texas;
and is state accredited in Colorado, Idaho, New Mexico, and Missouri. In addition,
A W AL is also accredited by the American Analytical Laboratory Association (A2LA) on
. ISO IEC 17025:2005, Department of Defense (DOD), UST for the State ofWyoming, and
the National Lead Laboratory Accreditation Program (NLLAP). All analyses were
performed in accordance to The NELAC Institute and/or A2LA protocols unless noted
otherwise. Accreditation documents are available upon request. If you have any
questions or concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction, and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be
reported by the method referenced and the sample matrix. The reporting limit must not be
confused with any regulatory limit. Analytical results are reported to three significant
figures for quality control and calculation purposes.
This is a revision to a report originally issued 8/31/2012. Pages 1, 14-16, and 39-41 have
been revised to evalutate down to the MDL.
Thank You, Ky I e F . Digitally signed by Kyle F. Gross

RE: Annual Tails 2012
Dear Garrin Palmer: Lab Set ID: 1210392
American West Analytical Laboratories received 2 sample( s) on 10/24/20 12 for the
analyses presented in the following report.
American West Analytical Laboratories (AWAL) is accredited by The National
Environmental Laboratory Association Conference (NELAC) Institute in Utah and Texas;
and is state accredited in Colorado, Idaho, New Mexico, and Missouri. In addition,
A W AL is also accredited by the American Analytical Laboratory Association (A2LA) on
ISO IEC 17025:2005, Department of Defense (DOD), UST for the State of Wyoming, and
the National Lead Laboratory Accreditation Program (NLLAP). All analyses were
performed in accordance to The NELAC Institute and/or A2LA protocols unless noted
otherwise. Accreditation documents are available upon request. If you have any
questions or concerns regarding this report please feel free to call.
The abbreviation "Surr" found in organic reports indicates a surrogate compound that is
intentionally added by the laboratory to determine sample injection, extraction,. and/or
purging efficiency. The "Reporting Limit" found on the report is equivalent to the
practical quantitation limit (PQL). This is the minimum concentration that can be
reported by the method referenced and the sample matrix. The reporting limit must not be
confused with any regulatory limit. Analytical results are reported to three significant
figures for quality control and calculation purposes.

Holding Time Requirements: The preparations and analyses of the samples were
performed within respective holding times.
Preparation Requirements: The samples were prepared and analyzed following the
. methods stated on the analytical reports.
Analytical QC Requirements: All instrument calibration and calibration check
requirements were met. Internal standard areas were outside. of the QC limits for samples
1210392-001A and -002A. Reanalysis or MS sample yielded similar results indicating
matrix interference.
Batch QC Requirements: MB, LCS, MS, MSD, RPD, and Surrogates:
Method Blanks: No target analytes were detected above reporting limits,
indicating that the procedure was free from contamination.
Laboratory Control Sample (LCS): All LCS recoveries were within control
limits, indicating that the preparation and analysis were in control.
Matrix Spike I Matrix Spike Duplicate (MS/MSD): Sample 1210392-001A
exhibited multiple percent recoveries outside of established limits indicating matrix
interference and multiple RPDs (Relative Percent Differences) were high due to
suspected sample non-homogeneity or matrix interference.
Surrogates: All surrogate recoveries were within established limits.
Corrective Action: None required.
