~-------------------
1.0 INTRODUCTION
The presence of chloroform was initially identified in groundwater at the White Mesa
Mill (the "Mill") as a result of split sampling performed in May 1999. The discovery
resulted in the issuance of State of Utah Notice of Violation ("NOV") and Groundwater
Corrective Action Order ("CAO") State of Utah Department of Environmental Quality
("UDEQ") Docket No. UGW-20-01, which required that Energy Fuels Resources (USA)
Inc. ("EFRI") submit a Contamination Investigation Plan and Report pursuant to the
provisions of UAC R317-6-6.15(D).
The frequency of chloroform sampling, which was initially performed on a monthly
basis, was modified on November 8, 2003. Since that time all chloroform contaminant
investigation wells have been sampled on a quarterly basis.
This is the Quarterly Chloroform Monitoring Report for the fourth quarter of 2012 as
required under the NOV and CAO. This Report also includes the Operations Report for
the Long Term Pump Test at MW-4, TW4-19, MW-26 (previously referred to as TW4-
15), TW4-20, and TW4-4 for the quarter.
2.0 CHLOROFORM MONITORING
2.1 Samples and Measurements Taken During the Quarter
A map showing the location of all groundwater monitoring wells, piezometers, existing
wells, temporary chloroform contaminant investigation wells and temporary nitrate
investigation wells is attached under Tab A. Chloroform samples and measurements
taken during this reporting period are discussed in the remainder of this section.
2.1.1 TW 4-27
Installation of the new perched groundwater monitoring well, TW 4-27, was completed on
November 8, 2011, as required by the May 26, 2011 DRC Request for Additional
Information ("RFI"), and as delineated in the Final EFRI Work Plan and Schedule to
Drill and Install Well TW4-27 (the "Plan"), submitted to DRC on October 3,2011.
Per section 1.2 of the Plan, water level and chloroform concentration data will be
collected from existing wells, as well as TW4-27, to determine if TW4-27 satisfies the
stipulated criteria. TW4-27 will satisfy the stipulated criteria if the 70 ug/L chloroform
isoconcentration line remains hydraulically up gradient of TW4-27, and groundwater
contour lines show that TW4-27 is hydraulically downgradient of TW4-4 and TW4-6.
In addition to the criteria in section 1.2, section 1.3 of the Plan states that if water level
data from TW 4-27 indicates that the water level at TW 4-14 is anomalous, TW 4-14 will
be abandoned, with the approval of the Director of the Division of Radiation Control. The
water level at TW 4-14 will be considered anomalous if the water level at TW 4-27 is
comparable to the water level at TW4-6.

N:\WMM\Required Reports\Chloroform Quarterly Monitoring Report\2012 Q4\2012_Q4Chloroform_Report_text.doc
First, second, third and fourth quarter 2012 water level and analytical data collected from
TW4-27 indicate that the 70 ug/L chloroform isoconcentration line remains hydraulically
upgradient of TW4-27, and that TW4-27 is hydraulically down gradient of TW4-4 and
TW 4-6, satisfying the criteria described above. Furthermore, because the water level at
TW4-27 is similar to the water level at TW4-14, but is approximately 14 feet lower than
the water level at TW 4-6, the water level at TW 4-14 is not considered anomalous, and
the section 1.3 abandonment criteria are not met.

Table 1 provides an overview of all wells sampled during the quarter, along with the date
samples were collected from each well, and the date(s) which analytical data were
received from the contract laboratory. Table 1 also identifies equipment rinsate samples
collected, as well as sample numbers associated with the deionized field blank ("DIFB")
and any required duplicates.
As indicated in Table 1, chloroform monitoring was performed in all of the required
chloroform monitoring wells.
2.1.3 Parameters Analyzed
Wells sampled during this reporting period were analyzed for the following constituents:
• Chloroform
• Chloromethane
• Carbon tetrachloride
• Methylene chloride
• Chloride
• Nitrate plus Nitrite as Nitrogen
Use of analytical methods is consistent with the requirements of the Chloroform
Investigation Monitoring Quality Assurance Program (the "Chloroform QAP") attached
as Appendix A to the White Mesa Uranium Mill Groundwater Monitoring QAP Revision
7.2, dated June 6, 2012.

N:\WMM\Required Reports\Chloroform Quarterly Monitoring Report\2012 Q4\2012_Q4Chloroform_Report_text.doc
2.1.4 Groundwater Head Monitoring
Depth to groundwater was measured in the following wells and/or piezometers, pursuant
to Part LE.3 of the Groundwater Discharge Permit (the "GWDP"):
• The quarterly groundwater compliance monitoring wells.
• Existing monitoring well MW -4 and all of the temporary chloroform investigation
wells.
• Piezometers -P-1, P-2, P-3, P-4 and P-5.
• MW-20andMW-22.
• Nitrate monitoring wells.
• The DR piezometers which were installed during the Southwest Hydrologic
Investigation.
• In addition to the above, depth to water measurements are routinely observed in
conjunction with sampling events for all wells sampled during quarterly and
accelerated efforts, regardless of the sampling purpose.
In addition, weekly and monthly depth to groundwater measurements were taken in MW-
4, MW-26, TW4-19, TW4-20, and TW4-4.
2.2 Sampling Methodology and Equipment and Decontamination Procedures
EFRI completed, and transmitted to UDEQ on May 25, 2006, a revised QAP for
sampling under the Mill's Groundwater Discharge Permit ("GWDP"). While the water
sampling conducted for chloroform investigation purposes has conformed to the general
principles set out in the QAP, some of the requirements in the QAP were not fully
implemented prior to UDEQ's approval, for reasons set out in correspondence to UDEQ
dated December 8, 2006. Subsequent to the delivery of the December 8, 2006 letter,
EFRI discussed the issues brought forward in the letter with UDEQ and has received
correspondence from UDEQ about those issues. In response to UDEQ's letter and
subsequent discussions with UDEQ, EFRI has incorporated changes in chloroform
Quality Assurance ("QA") procedures in the form of the Chloroform QAP. The
Chloroform QAP describes the needs of the chloroform investigation program where they
differ from the Groundwater QAP. On June 20, 2009 the Chloroform QAP was modified
to require that the quarterly chloroform reports include additional items specific to
EFRI's ongoing pump testing and chloroform capture efforts. The Groundwater QAP as
well as the Chloroform QAP were revised again on June 7, 2012. The revised
Groundwater QAP and Chloroform QAP, Revision 7.2 were approved by DRC on June
7,2012.
The sampling methodology, equipment and decontamination procedures that were used
for the chloroform contaminant investigation, as summarized below, are consistent with
the approved QAP Revision 7.2 and the Chloroform QAP.

N:\WMM\Required Reports\Chloroform Quarterly Monitoring Report\2012 Q4\2012_Q4Chloroform_Report_texLdoc
2.2.1 Well Purging and Depth to Groundwater
A list of the wells in order of increasing chloroform contamination is generated quarterly.
The order for purging is thus established. The list is included with the Field Data
Worksheets under Tab B. Mill personnel start purging with all of the non-detect wells
and then move to the more contaminated wells in order of chloroform contamination.
Samples are collected by means of disposable bailer(s) the day following the purging.
The disposable bailer is used only for the collection of a sample from an individual well
and disposed subsequent to the sampling. The wells are purged prior to sampling by
means of a portable pump. Each quarterly purging event begins at the location least
affected by chloroform (based on the previous quarter's sampling event) and proceeds by
affected concentration to the most affected location. As noted in the approved QAP,
Revision 7.2, purging will generally follow this order, and the sampling order may
deviate slightly from the generated list. This practice does not affect the samples for
these reasons: any wells sampled in slightly different order have either dedicated pumps
or are sampled via a disposable bailer. This practice does not affect the quality or
usability of the data as there will be no cross-contamination resulting from sampling
order.
Before leaving the Mill office, the portable pump and hose are rinsed with deionized
("DI") water. Where portable (non-dedicated) sampling equipment is used, a rinsate
sample will be collected at a frequency of one rinsate sample per 20 field samples. Well
depth measurements are taken and the one casing volume is calculated for those wells
which do not have a dedicated pump as described in Attachment 2-3 of the QAP. Purging
is completed to remove stagnant water from the casing and to assure that representative
samples of formation water are collected for analysis. There are three purging .strategies
that will be used to remove stagnant water from the casing during groundwater sampling
at the Mill. The three strategies are as follows:
1. Purging three well casing volumes with a single measurement of field parameters
specific conductivity, turbidity, pH, redox potential, and water temperature
2. Purging two casing volumes with stable field parameters for specific conductivity,
turbidity, pH, redox potential, and water temperature (within 10% RPD)
3. Purging a well to dryness and stability (within 10%) of field parameters for pH,
specific conductivity, and water temperature only after recovery
If the well has a dedicated pump, it is pumped on a set schedule per the remediation plan
and is considered sufficiently evacuated to immediately collect a sample; however, if a
pumping well has been out of service for 48 hours or more, EFRI will follow the purging
requirements outlined in Attachment 2-3 of the QAP. The dedicated pump is used to
collect parameters and to collect the samples as described below. If the well does not
have a dedicated pump, a Grundfos pump (9 -10 gpm pump) is then lowered to the
screened interval in the well and purging is started. The purge rate is measured for the
well by using a calibrated 5 gallon bucket. This purging process is repeated at each well
location moving from least contaminated to the most contaminated well. All wells are
capped and secured prior to leaving the sampling location.
4
N:\WMM\Required Reports\Chloroform Quarterly Monitoring Report\20l2 Q4\20l2_Q4Chloroform_Reporuext.doc
Wells with dedicated pumps are sampled when the pump is in the pumping mode. If the
pump is not pumping at the time of sampling, it is manually switched on by the Mill
Personnel. The well is pumped for approximately 5 to 10 minutes prior to the collection
of the field parameters. Per the approved QAP, one set of parameters is collected.
Samples are collected following the measurement of one set of field parameters. The
pump is turned off and allowed to resume its timed schedule.
2.2.2 Sample Collection
Samples are collected as described above. In all cases, on days when samples will be
collected, a cooler with ice is prepared. The trip blank is also gathered at that time (the
trip blank for these events is provided by the Analytical Laboratory). Once Mill
Personnel arrive at the well sites, labels are filled out for the various samples to be
collected. All personnel involved with the collection of water and samples are then
outfitted with rubber gloves. Chloroform investigation samples are collected by means of
disposable bailers.
Mill personnel use a disposable bailer to sample each well that does not have a dedicated
pump. The bailer is attached to a reel of approximately 150 feet of nylon rope and then
lowered into the well. After coming into contact with the water, the bailer is allowed to
sink into the water in order to fill. Once full, the bailer is reeled up out of the well and
the sample bottles are filled as follows:
• Volatile Organic Compound ("VOC") samples are collected first. This sample
consists of three 40 ml vials provided by the Analytical Laboratory. The VOC
sample is not filtered and is preserved with HCI;
• A sample for nitrate/nitrite is then collected. This sample consists of one 250 ml.
bottle which is provided by the Analytical Laboratory. The nitrate/nitrite sample
is also not filtered and is preserved with H2S04;
• A sample for chloride is then collected. This sample consists of one 500 ml.
bottle which is provided by the Analytical Laboratory. The chloride sample is
also not filtered and is not chemically preserved.
After the samples have been collected for a particular well, the bailer is disposed of and
the samples are placed into the cooler that contains ice. The well is then recapped and
Mill personnel proceed to the next well.
2.3 Field Data

All analytical results were provided by Energy Laboratories ("EL"). Table 1 lists the
dates when analytical results were reported to the QA Manager for each sample.
Results from analysis of samples collected for this quarter's chloroform contaminant
investigation are provided under Tab H of this Report. Also included under Tab Hare
the results of analyses for duplicate samples, the DIFB, and rinsate samples for this
sampling effort, as identified in Table 1, as well as results for trip blank analyses required
by the Chloroform QAP.
2.5.2 Regulatory Framework
As discussed in Section 1.0, above, the NOV and requirements of the CAO triggered a
series of actions on EFRI's part. In addition to the monitoring program, EFRI has
equipped five wells with pumps to recover impacted groundwater, and has initiated
recovery of chloroform from the perched zone.
Sections 4 and 5, below, interpret the groundwater level and flow information,
contaminant analytical results, and pump test data to assess effectiveness of EFRI's
chloroform capture program.
3.0 QUALITY ASSURANCE AND DATA VALIDATION
The QA Manager performed a QAlQuality Control ("QC") review to confirm compliance
of the monitoring program with requirements of the QAP. As required in the QAP, data
QA includes preparation and analysis of QC samples in the field, review of field
procedures, an analyte completeness review, and QC review of laboratory methods and
data. Identification of field QC samples collected and analyzed is provided in Section
3.1. Discussion of adherence to Mill sampling Standard Operating Procedures ("SOPs")
is provided in Section 3.2. Analytical completeness review results are provided in
Section 3.3. The steps and tests applied to check laboratory data QAlQC are discussed in
Sections 3.4.4 through 3.4.9 below.
6
N:\ WMM\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q4\20 12_ Q4Chloroform_Reporuext.doc
The analytical laboratory has provided summary reports of the analytical QAlQC
measurements necessary to maintain conformance with National Environmental
Laboratory Accreditation Conference ("NELAC") certification and reporting protocol.
The Analytical Laboratory QAlQC Summary Reports, including copies of the Mill's
Chain of Custody and Analytical Request Record forms for each set of Analytical
Results, follow the analytical results under Tab H. Results of review of the laboratory
QAlQC information are provided under Tab I and are discussed in Section 3.4, below.
3.1 Field QC Samples
The following QC samples were generated by Mill personnel and submitted to the
analytical laboratory in order to assess the quality of data resulting from the field
sampling program.
Field QC samples for the chloroform investigation program consist of one field duplicate
sample for each 20 samples, a trip blank for each shipped cooler which contains VOCs,
one DIFB and rinsate samples.
During this quarter, two duplicate samples were collected as indicated in Table 1. The
duplicates were sent blind to the analytical laboratory and analyzed for the same
parameters as the chloroform wells.
Two trip blanks were provided by Energy Laboratories and returned with the quarterly
chloroform monitoring samples.
Two rinsate blank samples were collected at a frequency of one rinsate per twenty
samples per QAP Section 4.3.2 and as indicated on Table 1. Rinsate samples were
labeled with the name of the subsequently purged well with a terminal letter "R" added
(e.g. TW4-7R). The results of these analyses are included with the routine analyses under
TabH.
In addition, one DIFB, while not required by the Chloroform QAP, was collected and
analyzed for the same constituents as the well samples and rinsate blank samples.
3.2 Adherence to Mill Sampling SOPs
On a review of adherence by Mill personnel to the existing sampling SOPs, the QA
Manager observed that QAlQC requirements established in the QAP and Chloroform
QAP were being adhered to.
3.3 Analyte Completeness Review
All analyses required by the CAO for chloroform monitoring for the period were
performed.
7
N:\WMM\Required Reports\Chlorofonn Quarterly Monitoring Report\2012 Q4\2012_Q4Chloroform_Report_text.doc
3.4 Data Validation
The QAP and GWDP identify the data validation steps and data QC checks required for
the chloroform monitoring program. Consistent with these requirements, the QA
Manager performed the following evaluations: a field data QAlQC evaluation, a holding
time check, a receipt temperature check, an analytical method check, a reporting limit
evaluation, a trip blank check, a QAlQC evaluation of sample duplicates, a QC Control
Limit check for analyses and blanks/ including the DIFB and a rinsate sample check.
Each evaluation is discussed in the following sections. Data check tables indicating the
results of each test are provided under Tab I.
3.4.1 Field Data QAlQC Evaluation
The QA Manager performs a review of all field recorded parameters to assess their
adherence with QAP requirements. The assessment involved review of two sources of
information: the Field Data Sheets and the Quarterly Depth to Water summary sheet.
Review of the Field Data Sheets addresses well purging volumes and measurement of
field parameters based on the requirements discussed in section 2.2.1 above. The purging
technique employed determines the requirements for field parameter measurement and
whether stability criteria are applied. Review of the Depth to Water data confirms that all
depth measurements used for development of groundwater contour maps were conducted
within a five-day period as indicated by the measurement dates in the summary sheet
under Tab D. The results of this quarter's review of field data are provided under Tab I.
Based upon the review of the field data sheets, all wells conformed to the QAP purging
and field measurement requirements. A summary of the purging techniques employed
and field measurements taken is described below:
Purging Two Casing Volumes with Stable Field Parameters (within 10% RPD)
Wells TW4-01, TW4-05, TW4-08, TW4-09, TW4-11, TW4-12, TW4-16, MW-32, TW4-
18, TW4-21, TW4-23 , TW4-24, and TW4-25 were sampled after two casing volumes
were removed. Field parameters pH, specific conductivity, turbidity, water temperature,
and redox potential were measured during purging. All field parameters for this
requirement were stable within 10% RPD.
Purging a Well to Dryness and Stability of a Limited List of Field Parameters
Wells TW4-2, TW4-3, TW4-6, TW4-7, TW4-10, TW4-13, TW4-14, TW4-22, TW4-26,
and TW 4-27 were pumped to dryness before two casing volumes were evacuated. After
well recovery, one set of measurements were taken, the samples were collected, and
another set of measurements were taken. Stabilization of pH, conductivity and
temperature are required within 10% RPD under the QAP, Revision 7.2. It is important
to note that redox potential and turbidity were measured as well during purging and
sampling. Turbidity measurements were not within 10% RPD; however, these turbiduty
and redox potential are not required to be measured or to be within 10% RPD per the
approved QAP, Revision 7.2. Data from measurement of these parameters has been
provided for information purposes only.
During review of the field data sheets, it was observed that sampling personnel
8
N:\WMM\Required Reports\Chlorofonn Quarterly Monitoring Report\2012 Q4\2012_Q4Chloroform_Report_texLdoc
consistently recorded depth to water to the nearest 0.01 foot.
The review of the field sheets for compliance with QAP, Revision 7.2 requirements
resulted in the observations noted below. The QAP requirements in Attachment 2-3
specifically state that field parameters must be stabilized to within 10% over at least 2
consecutive measurements for wells purged to 2 casing volumes or purged to dryness.
The QAP Attachment 2-3 states that turbidity should be less than 5 NTU prior to
sampling unless the well is characterized by water that has a higher turbidity. The QAP
Attachment 2-3 does not require that turbidity measurements be less than 5 NTU prior to
sampling. As such the noted observations regarding turbidity measurements greater than
5 NTU below are included for information purposes only.
Wells TW4-01, TW4-03, TW4-04, TW4-05, TW4-06, TW4-07, TW4-08, TW4-09,
TW4-10, TW4-11, TW4-12, TW4-14, TW4-16, TW4-18, TW4-21, TW4-22, TW4-23,
TW4-24, TW4-25, TW4-26, and TW4-27 exceeded the QAP's 5 NTU goal. The QAP
does not require that turbidity measurements be less than 5 NTU prior to sampling. Of the
twenty-one samples, ten samples (TW4-2, TW4-3, TW4-6, TW4-7, TW4-10, TW4-13,
TW4-14, TW4-22, TW4-26, and TW4-27) were taken after the well had been pumped to
dryness. In wells that are purged to dryness, turbidity is not required per the QAP,
Revision 7.2. As such, the noted observations regarding turbidity measurements less than
5 NTU are included for information purposes only.
EFRI's letter to DRC of March 26, 2010 discusses further why turbidity does not appear
to be an appropriate parameter for assessing well stabilization. In response to DRC's
subsequent correspondence dated June 1, 2010 and June 24, 2010, EFRI has completed a
monitoring well redevelopment program. The redevelopment report was submitted to
DRC on September 30, 2011. DRC responded to the redevelopment report via letter on
November 15, 2012. Per the DRC letter dated November 15, 2012, the field data
generated this quarter are compliant with the turbidity requirements of the approved
QAP.
3.4.2 Holding Time Evaluation
QAP Table 1 identifies the method holding times for each suite of parameters. Sample
holding time checks are provided in Tab I. All samples were received and analyzed
within the required holding times.
3.4.3 Receipt Temperature Evaluation
Chain of Custody sheets were reviewed to confirm compliance with the QAP requirement
which specifies that samples be received at 6°C or lower. Sample temperatures checks
are provided in Tab I. All samples were received within the required temperature limit.
3.4.4 Analytical Method Checklist
All analytical methods reported by the laboratory were checked against the required
methods enumerated in the Chloroform QAP. Analytical method checks are provided in
Tab I. All methods were consistent with the requirements of the Chloroform QAP.

3.4.5 Reporting Limit Evaluation
All analytical method reporting limits reported by the laboratory were checked against
the reporting limits enumerated in the Chloroform QAP. Reporting Limit Checks are
provided under Tab I. All analytes were measured and reported to the required reporting
limits, except 30 sets (28 samples and 2 duplicates) of sample results had the reporting
limit raised for at least one analyte due to matrix interference and/or sample dilution. In
all cases the reported value for the analyte was higher than the increased detection limit.
3.4.6 Receipt pH Evaluation
Appendix A of the QAP states that all volatile samples are required to be preserved and
arrive at the laboratory with a pH less than 2. A review of the laboratory data revealed
that all volatile samples were received at the laboratory with a pH less than 2.
3.4.7 Trip Blank Evaluation
All trip blank results were reviewed to identify any VOC contamination resulting from
transport of the samples. Trip blank checks are provided in Tab I. All trip blank results
were less than the reporting limit for all VOCs.
3.4.8 QAlQC 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
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
EP A 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 reported detection limit
and the RPD is greater than 20%. The additional duplicate information is provided for
information purposes.
All analytical results for the sample/duplicate pairs were within the 20% acceptance
limits. All results of the RPD test are provided in Tab I.
3.4.9 Rinsate Sample Check
Rinsate blank sample checks are provided in Tab I. A comparison of the rinsate blank
sample concentration levels to the QAP requirements -that rinsate sample concentrations
be one order of magnitude lower than that of the actual well -indicated that one of the
two rinsate blank analytes met this criterion. Rinsate sample TW4-21R reported
chloroform at 16.0 ug/L and sample TW4-21 reported a chloroform concentration of 390
ug/L. The rinsate sample TW4-21R is therefore compliant with the QAP requirements.
Rinsate sample TW 4-3R had a reported detection of chloroform of 2.0 ug/L while
10
N:\WMM\Required Reports\Chloroform Quarterly Monitoring Report\2012 Q4\2012_Q4Chloroform_ReporuexLdoc
chloroform was not detected in sample TW4-3. The rinsate sample TW4-3R is not
compliant with the QAP requirements that the rinsate concentration be one order of
magnitude lower than that of the actual well. The results of an investigation into the
rinsate blank contamination are described below and a corrective action is described in
Section 6.0.
While not required by the Chloroform QAP, DlFB samples are collected to analyze the
quality of the DI water system at the Mill, which is also used to collect rinsate samples. A
review of the analytical results reported for the DlFB sample indicated the sample
contained chloroform at 2.0 ug/L. Further review of the data package showed that the
DlFB sample as well as the rinsate sample TW4-21R were analyzed by the lab
immediately after samples with the high levels of chloroform. TW4-21R was analyzed
after a sample with a chloroform concentration of 708 ug/L, and TW4-60 was analyzed
after a sample with a chloroform concentration of 1200 ug/L. The detections in TW 4-60
and TW4-21R are carry-over resulting from the samples analyzed previously. TW4-3R
was the first EFRI sample reported in the data package; however, it was not the first
sample analyzed on that instrument on that day and was most likely analyzed after a
sample with high concentrations of chloroform. The detection in TW 4-3R is carry-over
resulting from the samples analyzed previously. As analytical data from other clients is
confidential, EFRI cannot request the analytical data for the sample preceding TW4-3R.
The rinsate samples are analyzed at the end of the analytical run after the highest level
samples. Due to continued issues with Energy Laboratories, EFRI has changed
laboratories for the first Quarter 2013 sampling event.
3.4.10 Other Laboratory QAlQC
Section 9.2 of the QAP requires that the laboratory's QAlQC 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 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-specified acceptance limits, or that the case narrative sufficiently
explains any deviation from these limits. Results of this quantitative check are provided
in Tab I.
All lab QAlQC results met these specified acceptance limits except as noted below.
The QAP Section 8.1.2 requires that a Matrix SpikelMatrix Spike Duplicate
("MSIMSD") pair be analyzed with each analytical batch. The QAP does not specify
acceptance limits for the MSIMSD pair, and the QAP does not specify that the MSIMSD
pair be prepared on EFRI samples only. Acceptance limits for MSIMSDs 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 an MSIMSD pair with each
analytical batch was met. While the QAP does not require it, the recoveries were
11
N:\WMM\Required Reports\Chloroform Quarterly Monitoring Report\20l2 Q4\2012_Q4Chloroform_Report_text.doc
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 QAlQC Summary Reports indicates that the
MSIMSDs recoveries and the associated RPDs for all quarterly chloroform samples are
within acceptable laboratory limits for all regulated compounds except as indicated in
Tab I. One MSIMSD recovery RPD was outside the laboratory established acceptance
limits. This result does not affect the quality or usability of the data because the recovery
above the acceptance limits is indicative of matrix interference. The MSIMSD recovery
was above the laboratory established acceptance limits, indicating a high bias to the
individual sample results. A high bias means that reported results may be higher than the
actual results. The recovery does not affect the quality or usability of the data because
the recovery outside of the acceptance limits is indicative of matrix interference. The
QAP requirement to analyze a MSIMSD pair with each analytical batch was met and as
such the data are compliant with the QAP.
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 QAlQC Summary Reports indicates that the
surrogate recoveries for all quarterly chloroform samples were within acceptable
laboratory limits for all surrogate compounds except as indicated in Tab I. One surrogate
recovery was above the laboratory established acceptance limits, indicating a high bias to
the individual sample results. A high bias means that reported results may be higher than
the actual results. Furthermore, there are no QAP requirements for surrogate recoveries.
The information from the Laboratory QAlQC Summary Reports indicates that all LCS
recoveries were within acceptable laboratory limits for all LCS compounds as indicated
in Tab I.
4.0 INTERPRETATION OF DATA
4.1 Interpretation of Groundwater Levels, Gradients and Flow Directions.
4.1.1 Current Site Groundwater Contour Map
The water level contour maps indicate that perched water flow ranges from generally
southwesterly beneath the Mill site and tailings cells to generally southerly along the
eastern and western margins of White Mesa. Perched water mounding associated with the
wildlife ponds locally changes the flow patterns. For example, northeast of the Mill site,
mounding associated with wildlife ponds results in locally northerly flow near MW-19.
The impact of the water level mound associated with the northern ponds, to which water
is no longer delivered, is diminishing and is expected to continue to diminish as the water
level mound decays due to reduced recharge. Flow directions are also locally influenced
by pumping at MW-4, MW-26, TW4-4, TW4-19, and TW4-20. Significant cones of
depression have formed in the vicinity of all pumping wells except TW 4-4, which began
pumping in the first quarter of 2010.
12
N:\ WMM\Required Reports\Chloroform Quarterly Monitoring Report\20 12 Q4\20 12_ Q4Chloroform_Reporuext.doc
Although pumping at TW 4-4 has depressed the water table in the vicinity of TW 4-4, a
well-defined cone of depression is not evident. The lack of a well-defined cone of
depression likely results from 1) variable permeability conditions in the vicinity of TW4-
4, and 2) persistent relatively low water levels at adjacent well TW4-14.
Changes in water levels at wells immediately south of TW4-4 resulting from TW4-4
pumping are expected to be muted because TW 4-4 is located at a transition from
relatively high to relatively low permeability conditions south (downgradient) of TW 4-4.
The permeability of the perched zone at TW 4-6 and TW 4-26 is approximately two orders
of magnitude lower than at TW4-4. Any drawdown of water levels at wells immediately
south of TW 4-4 resulting from TW 4-4 pumping is also difficult to determine because of a
general, long-term increase in water levels in this area. Water levels at TW 4-4 and TW 4-
6 increased by nearly 2.7 and 2.9 feet, respectively, between the fourth quarter of 2007
and the fourth quarter of 2009 Gust prior to TW 4-4 pumping) at rates of approximately
1.2 feet/year and 1.3 feet/year, respectively. However, the increase in water level at TW4-
6 has been reduced since the start of pumping at TW4-4 (first quarter of 2010) to less
than 0.5 feet/year suggesting that TW 4-6 is within the hydraulic influence of TW 4-4.
The lack of a well-defined cone of depression at TW4-4 is also influenced by the
persistent, relatively low water level at non-pumping well TW4-14, located east of TW4-
4 and TW4-6. For the current quarter, the water level at TW4-14 (approximately 5525.91
feet above mean sea level [ft amsl]) is approximately 13 feet lower than the water level
at TW4-6 (approximately 5538.74 ft amsl) and nearly 18 feet lower than at TW4-4
(approximately 5543.51 ft amsl) even though TW4-4 is pumping.
Well TW4-27 (installed south of TW4-14 in the fourth quarter of2011) has a static water
level of approximately 5525 ft amsl, similar to TW4-14. TW4-27 was positioned at a
location considered likely to detect any chloroform present and/or to bound the
chloroform plume to the southeast and east of TW 4-4 and TW 4-6. As will be discussed
below, groundwater data collected since installation indicates that TW4-27 does indeed
bound the chloroform plume to the southeast and east of TW 4-4 and TW 4-6.
Prior to the installation of TW4-27, the persistently low water level at TW4-14 was
considered anomalous because it appeared to be downgradient of all three wells TW 4-4,
TW4-6, and TW4-26, yet chloroform was not detected at TW4-14. Chloroform had
apparently migrated from TW4-4 to TW4-6 and from TW4-6 to TW4-26 which
suggested that TW4-26 was actually downgradient of TW4-6, and TW4-6 was actually
downgradient of TW 4-4, regardless of the flow direction implied by the low water level
at TW4-14. The water level at TW4-26 (5538.2 feet amsl) is, however, lower than water
levels at adjacent wells TW4-6 (5538.7 feet amsl), and TW4-23 (5542.6 feet amsl)
Hydraulic tests conducted in November, 2011 indicate that the permeability at TW4-27 is
an order of magnitude lower than at TW 4-6 and three orders of magnitude lower than at
TW4-4. The similar water levels at TW4-14 and TW4-27, and the low permeability
estimate at TW 4-27 suggest that both wells are completed in materials having lower
permeability than nearby wells. The low permeability condition likely reduces the rate of
long-term water level increase at TW4-14 and TW4-27 compared to nearby wells,
13
N:\WMM\Required Reports\Chloroform Quarterly Monitoring Report\2012 Q4\2012_Q4Chloroform_Report_text.doc
yielding water levels that appear anomalously low. The low permeability condition is
expected to retard the transport of chloroform to TW 4-14 and TW 4-27 (compared to
nearby wells). As will be discussed in Section 4.2.3, fourth quarter, 2012 chloroform
concentrations at TW4-26 and TW4-27 are 5.9 ug/L and non-detect, respectively and
both wells are outside the chloroform plume.
4.1.2 Comparison of Current Groundwater Contour Maps to Groundwater
Contour Maps for Previous Quarter
The groundwater contour maps for the Mill site for the third quarter of 2012, as submitted
with the Chloroform Monitoring Report for the third quarter of 2012, are attached under
TabE.
A comparison of the water table contour maps for the current (fourth) quarter of 2012 to
the water table contour maps for the previous quarter (third quarter of 2012) indicates
similar patterns of draw down related to pumping of MW-4, MW-26, TW4-4, TW4-19
and TW4-20. Water levels and water level contours for the site have not changed
significantly since the last quarter, except for a few locations. As discussed in Section
4.1.1, pumping at TW4-4, which began in the first quarter of 2010, has depressed the
water table near TW4-4, but a well-defined cone of depression is not yet evident, likely
due to variable permeability conditions near TW4-4 and the persistently low water level
at adjacent well TW4-14.
Reported increases in water levels (decreases in drawdown) of approximately 6 feet and
of approximately 3 feet occurred in pumping wells MW-26 and TW4-20, respectively,
and a decrease in water level (increase in drawdown) of approximately 3 feet occurred in
pumping well TW 4-19. Changes in water levels at other pumping wells (MW -4 and
TW4-4) were less than 1 foot. Water level fluctuations at pumping wells MW-4, MW-26,
TW4-4, TW4-19, and TW4-20 typically occur in part because of fluctuations in pumping
conditions just prior to and at the time the measurements are taken.
The increases in water levels (decreases in draw down) at MW-26 and TW4-20 have
slightly decreased the apparent capture of these wells relative to other pumping wells and
the decrease in water level (increase in draw down) at TW4-19 has increased its apparent
capture relative to other pumping wells. Overall, the combined capture of MW -4, MW-
26, TW4-4, TW4-19, and TW4-20 has changed only slightly since the last quarter.
Decreases in water levels of approximately 4 feet, of approximately 3 feet, and of
approximately 6 feet occurred in non-pumping wells MW-20, MW-37, and TW4-12,
respectively. The reported water level at PIEZ-2, located between the northern wildlife
ponds, increased by nearly 7 feet, and water level increases of approximately 3 feet and
of approximately 2 feet occurred at wells TWN-2 and TWN-4. Water level changes at
other non-pumping wells were less than 2 feet. The water level change at PIEZ-2
suggests increased natural recharge in the vicinity of the northern wildlife ponds since
last quarter and represents a partial reversal in the general decrease in water level at
PIEZ-2 since the cessation of water delivery to the northern wildlife ponds.

chloroform contaminant investigation monitor well over time.
4.1.4 Depth to Groundwater Measured and Groundwater Elevation
Attached under Tab G are tables showing depth to groundwater measured and
groundwater elevation over time for each of the wells listed in Section 2.1.1 above.
4.1.5 Evaluation of the Effectiveness of Hydraulic Capture
Perched water containing chloroform has been removed from the subsurface by pumping
MW-4, MW-26, TW4-4, TW4-19, and TW4-20. The primary purpose of the pumping is
to reduce total chloroform mass in the perched zone as rapidly as is practical. Pumping
wells up gradient of TW 4-4 were chosen for pumping because 1) they are located in areas
of the perched zone having relatively high permeability and saturated thickness, and 2)
high concentrations of chloroform were detected at these locations. The relatively high
transmissivity of the perched zone in the vicinity of these pumping wells results in the
wells having a relatively high productivity. The combination of relatively high
productivity and high chloroform concentrations allows a high rate of chloroform mass
removal. TW 4-4 is located in a downgradient area having relatively high chloroform
concentrations but relatively small saturated thickness, and at a transition from relatively
high to relatively low permeability conditions downgradient of TW 4-4. As with the other
pumping wells, pumping TW 4-4 helps to reduce the rate of chloroform migration in
downgradient portions of the plume.
The impact of pumping is indicated by the water level contour maps attached under Tabs
D and E. Cones of depression have developed in the vicinity of MW -4, MW -26, TW 4-
19, and TW 4-20 which continue to remove significant quantities of chloroform from the
perched zone. The water level contour maps indicate effective capture of water
containing high chloroform concentrations in the vicinities of these pumping wells.
Overall, the combined capture ofMW-4, MW-26, TW4-19, and TW4-20 has not changed
significantly since the last quarter. As discussed in Section 4.1.1, the drawdown
associated with TW 4-4 is likely less apparent due to variable permeability conditions
near TW4-4 and the persistently low water level at adjacent well TW4-14.
Chloroform concentrations exceeding 70 IlglL have occurred in the past at some
locations down gradient of pumping wells (for example, at TW4-6, located immediately
south of TW4-4), where the lower permeability and relatively small saturated thickness
of the perched zone significantly limits the rate at which chloroform mass can be
removed by pumping. By removing mass and reducing hydraulic gradients, thereby
reducing the rate of down gradient chloroform migration, and allowing natural attenuation
to be more effective, pumping at the productive, up gradient locations has a beneficial
effect on this down gradient chloroform. Pumping at TW 4-4 was implemented during the
first quarter of 2010 to improve capture in this downgradient area to the extent allowable
by the lower productivity conditions presumed to exist in this area. The beneficial effect
of pumping TW 4-4 is demonstrated by the decrease in chloroform concentrations at
15
N:\WMM\Required Reports\Chloroform Quarterly Monitoring Report\2012 Q4\2012_Q4Chloroform_Report_texLdoc
TW4-6 from 1,000 ~glL to 8.5 ~glL, and at TW4-26 from 13 ~glL to 5.9 ~glL since
pumping began at TW 4-4. Concentrations at these wells have decreased substantially
even though they do not unambiguously appear to be within the hydraulic capture of
TW4-4. As discussed in Section 4.1.1, however, the decrease in the long-term rate of
water level rise at TW 4-6 since pumping began at TW 4-4 does suggest that TW 4-6 is
within the hydraulic influence of TW 4-4. Regardless of whether TW 4-6 can be
demonstrated to be within hydraulic capture of TW 4-4, pumping TW 4-4 reduces
chloroform migration to TW 4-6 and TW 4-26 by the mechanisms discussed above.
4.2 Review of Analytical Results
4.2.1 Current Chloroform Isoconcentration Map
Included under Tab J of this Report is a current chloroform isoconcentration map for the
Mill site.
4.2.2 Chloroform Concentration Trend Data and Graphs
Attached under Tab K are tables summarizing values for all required parameters,
chloride, nitrate/nitrite, carbon tetrachloride, chloroform, chloromethane, and methylene
chloride, for each well over time.
Attached under Tab L are graphs showing chloroform concentration trends in each
monitor well over time.
4.2.3 Interpretation of Analytical Data
Comparing the analytical results to those of the previous quarter, as summarized in the
table included under Tab K, the following observations can be made:
a) Chloroform concentrations have increased by more than 20% in the following
wells compared to last quarter: TW4-6, TW4-19, TW4-20, and TW4-26;
b) Chloroform concentrations have decreased by more than 20% in the following
wells compared to last quarter: MW-26, TW4-5, TW4-18, and TW4-22;
c) Chloroform concentrations have remained within 20% in the following wells
compared to last quarter: MW-4, TW4-1, TW4-2, TW4-4, TW4-7, TW4-10,
TW4-11, TW4-21, and TW4-24;
d) MW-32, TW4-3, TW4-8, TW4-9, TW4-12, TW4-13, TW4-14, TW4-16, TW4-
23, TW4-25 and TW4-27 remained non-detect; and
e) Chloroform concentrations at TW 4-24 remained at 1.1 ~ gIL.
As indicated, chloroform concentrations at many of the wells with detected chloroform
were within 20% of the values reported for the wells during the previous quarter,
suggesting that variations are within the range typical for sampling and analytical error.
16
N:\WMM\Required Reports\Chloroforrn Quarterly Monitoring Report\2012 Q4\2012_Q4Chloroform_Report_texLdoc
Wells MW-26, TW4-5, TW4-6, TW4-18, TW4-19, TW4-20, TW4-22 and TW4-26 had
changes in concentration greater than 20%. Of the latter, MW-26, TW4-19, and TW4-20
are pumping wells. TW4-5 and TW4-22 are located adjacent to pumping well TW4-20;
TW4-18 is located adjacent to pumping well TW4-19; and TW4-6 is located adjacent to
pumping well TW 4-4. Fluctuations in concentrations at pumping wells and wells
adjacent to pumping wells likely result in part from changes in pumping. TW4-26 is
located outside of the chloroform plume near the downgradient edge of the plume. Slight
expansion and contraction of the chloroform plume boundaries in response to changes in
upgradient pumping are expected to impact the concentrations at TW4-26.
Pumping well TW 4-20 had the highest detected chloroform concentration. Since the last
quarter, the chloroform concentration in TW4-20 increased from 13,000 ~glL to 19,000
~glL, the concentration in adjacent pumping well TW4-19 increased from 950 ~glL to
1,500 ~glL, the concentration in nearby well TW4-21 decreased slightly from 410 to 390
~glL, and the concentration in nearby well TW4-22 decreased from 940 ~glL to 330
~glL. Wells TW4-23 and TW4-25 remained non-detect for chloroform. The
concentration in well TW4-24 remained at 1.1 ~glL. TW4-24, located west of TW4-22,
and TW 4-25, located north of TW 4-21, bound the chloroform plume to the west and
north. In addition, the southernmost boundary of the plume remains between TW 4-4 and
TW 4-6 (located just north of southernmost temporary well TW 4-26).
The chloroform concentration in TW4-6 increased from 6.9 ~glL to 8.5 ~glL, and
remains outside the chloroform plume boundary. Concentrations at TW 4-6 have, since
initiation of pumping of TW4-4 in the first quarter of 2010, decreased from 1,000 ~glL to
8.5 ~glL. TW4-6, installed in the second quarter of 2000, was the most downgradient
temporary perched well prior to installation of temporary well TW 4-23 in 2007 and
temporary well TW4-26 in the second quarter of 2010. TW4-6 remained outside the
chloroform plume between the second quarter of 2000 and the fourth quarter of 2008.
TW 4-6 likely remained outside the chloroform plume during this time due to a
combination of 1) slow rates of downgradient chloroform migration in this area due to
low permeability conditions and the effects of upgradient chloroform removal by
pumping, and 2) natural attenuation. Because TW 4-6 is again outside the plume
boundary, TW4-6and TW4-23 bound the chloroform plume to the south. TW4-8, TW4-
12, TW4-13, TW4-14, and TW4-27 bound the chloroform plume to the east.
The slow rate of chloroform migration in the vicinity of TW 4-6 is demonstrated by
comparing the rate of increase in chloroform at this well to the rate of increase in the
nearest up gradient well TW 4-4. Concentrations at TW 4-4 increased from non-detect to
more than 2,200 ~glL within only 2 quarters whereas 16 quarters were required for
concentrations in TW4-6 to increase from non-detect to only 81 ~glL. This behavior is
consistent with hydraulic tests performed at TW4-4, TW4-6, and TW4-26 during the
third quarter of 2010 that indicate a nearly two order of magnitude decrease in
permeability down gradient of TW 4-4. Chloroform migration rates in the vicinity of
wells TW4-26 and TW4-27 are also expected to be relatively low due to up gradient
pumping and low permeability conditions.

5.0 LONG TERM PUMP TEST AT MW-4, MW-26, TW4-19, TW4-20, AND
TW4-4 OPERATIONS REPORT
5.1 Introduction
As a part of the investigation of chloroform contamination at the Mill site, EFRI has been
conducting a Long Term Pump Test on MW-4, TW4-19, MW-26, and TW4-20, and,
since January 31, 2010, TW4-4. The purpose of the test is to serve as an interim action
that will remove a significant amount of chloroform-contaminated water while gathering
additional data on hydraulic properties in the area of investigation. The following
information documents the operational activities during the quarter.
5.2 Pump Test Data Collection
The long term pump test for MW-4 was started on April 14,2003, followed by the start
of pumping from TW4-19 on April 30, 2003, from MW-26 on August 8, 2003, from
TW4-20 on August 4, 2005, and from TW4-4 on January 31, 2010. Personnel from
Hydro Geo Chern, Inc. were on site to conduct the first phase of the pump test and collect
the initial two days of monitoring data for MW -4. EFRI personnel have gathered
subsequent water level and pumping data.
Analyses of hydraulic parameters and discussions of perched zone hydrogeology near
MW-4 has been provided by Hydro Geo Chern in a separate report, dated November 12,
2001, and in the May 26,2004 Final Report on the Long Term Pumping Test.
Data collected during the quarter included the following:
• Measurement of water levels at MW-4, TW4-19, MW-26, and TW4-20
and, commencing regularly on March 1,2010, TW4-4, on a weekly basis,
and at selected temporary wells and permanent monitoring wells on a
monthly basis.
• Measurement of pumping history, including:
pumping rates
total pumped volume
operational and non-operational periods.
• Periodic sampling of pumped water for chloroform and nitrate/nitrite
analysis and other constituents
5.3 Water Level Measurements
Beginning August 16, 2003, the frequency of water level measurements from MW-4,
MW-26, and TW4-19 was reduced to weekly. From commencement of pumping TW4-
20, and regularly after March 1, 2010 for TW4-4, water levels in these wells have been
measured weekly. Depth to groundwater in all other chloroform contaminant
investigation wells is monitored monthly. Copies of the weekly Depth to Water
monitoring sheets for MW-4, MW-26, TW4-19, TW4-20 and TW4-4 and the monthly

wells are included under Tab C. Monthly depth to water measurements for the quarter
are recorded in the Field Data Worksheets included under Tab D.
5.4 Pumping Rates and Volumes
Table 2 summarizes the recovered mass of chloroform by well per quarter and
historically since the inception of the chloroform recovery program for the five currently-
active pumping wells.
All of the pumping wells do not pump continuously, but are on a delay device. The wells
purge for a set amount of time and then shut off to allow the well to recharge. Water
from the pumping wells is transferred to the Cell 1 evaporation pond through a pipeline
installed specifically for that purpose. The pumping rates and volumes for each of the
pumping wells are shown in Table 3. Unless specifically noted below, no operational
problems observed with the well or pumping equipment during the quarter.
Due to extremely cold weather conditions during December 2012, multiple freeze related
power issues were noted at the Mill. The power issues affected the pumping systems as
noted below.
5.4.1 TW4-4
Several power related issues were noted during December 2012. As noted above,
extremely cold temperatures caused widespread power issues across the Mill.
On December 11, 2012, a power line which services a large section of the Mill was hit by
a vehicle and power was lost to TW 4-4 and MW -4. The line was fixed and power was
restored to TW 4-4 and MW -4 within a few hours. The outage lasted less than 24 hours
and did not require any notifications to DRC.
On December 24, 2012, the Mill Field Personnel noted that the pump in TW4-4 was
operating properly, but the heat lamp was not operating. The Ground Fault Circuit
Interupter ("GFCI") was noted by Mill Field Personnel as being faulty. The GFCI was
replaced by the Mill Maintenance Staff within 24 hours, hence no notofocation to DRC
was required. During the weekly check on December 31,2012, it was noted that the heat
lamp had melted the flow totalizer at the well. The pump was not affected and pumping
continued uninterrupted; however, the totalizer was not recording the volume pumped.
The flow totalizer was replaced within 24 hours of the discovery, and no notification to
DRC was required.
The Mill's Operations and Maintenance Plan, Chloroform Pumping System, White Mesa
Mill, Blanding, Utah, Revision 2.1 ("O&M Plan") states that:
"When a system failure occurs and is not repaired and made fully operational within 24
hours of discovery, EFRI shall call the Director to verbally report the system failure and
will report to the Director in a written report within 5 days of the failure.
19
N:\WMM\Required Reports\Chlorofonn Quarterly Monitoring Report\2012 Q4\2012_Q4Chloroform_Reporuext.doc
EFRI notified DRC Personnel via telephone on December 31,2012, that the pumping
"system" did not fail and chloroform capture was not affected. However, some volume
has been pumped, and some chloroform capture has occurred, which is not counted by
the totalizer in the short period it was out of service.
Per DRC instructions during the December 31,2012 phone call, EFRI completed the
following actions:
1. EFRI will estimate the typical or average flow from a period when the totalizer
functioned properly, and apply that estimated rate for the short period when the
totalizer was not functioning. That flow estimate will be included in calculating
the total pumped flow reported in this chloroform quarterly report.
2. EFRI is documenting the meter damage and replacement in this chloroform
quarterly report.
Per the telephone conversations with DRC Personnel on December 31,2012, a 5-day
written report was not required.
The estimated volume added to the quarterly total for TW4-4 was calculated as follows:
• The average pump rate recorded during the 4th quarter 2012 (as shown in Table 3)
is 13.6 gallons per minute ("GPM").
• The average gallons pumped per week is calculated as the total pumped for the
quarter (66,089) divided by 12 weeks (total number of weeks in the quarter that
the flow meter recorded). The average gallons pumped per week is 66,089/12 =
5 ,507 gallons per week.
• The concentration of chloroform in TW 4-4 used for calculation of pounds
removed is 1400 ug/L.
• Based on the average flow rates, concentration and average gallons pumped, an
additional 0.1 pounds of chloroform were removed during the week that the flow
totalizer was not recording (December 24,2012 through December 31,2012)
5.4.2 MW-4
On December 11, 2012, a power line which services a large section of the Mill was hit
and power was lost to TW 4-4 and MW -4. The line was fixed and power was restored to
TW4-4 and MW-4 within a few hours. However, during the power outage the heat lamp
in MW -4 was not operating and the flow meter froze and broke. The power was restored
and the flow meter was replaced in less than 24 hours, hence no notifications to DRC
were required.
5.2.3 MW-26 and TW4-20
On Wednesday, December 19, 2012 a transformer failure had occurred which required
more than 24 hours to be repaired. The failure shut down electrical power to MW -26
and TW4-20. These chloroform continuous pumping wells were off (not pumping) until
an interim source of power was provided. Initial notice of this outage was given by
20
N:\WMM\Required Reports\Chlorofonn Quarterly Monitoring Report\2012 Q4\2012_Q4Chloroform_Report_texLdoc
telephone to Mr. Dean Henderson of DRC at approximately 3:40 pm on Wednesday
December 19, 2012 (within 24 hours of the discovery).
The Mill's Chloroform O&M Plan, submitted on October 25,2010 and under review by
UDEQ at the time of this incident, states that EFRI will notify UDEQ of system failures
that cannot be "repaired and fully made operational within 24 hours of discovery."
During the morning of December 20, 2012, Mill management determined that a
replacement for the damaged transformer would require up to 2 weeks or longer for
delivery to the Mill site. On December 20, 2012, Mill management began moving
gasoline driven generators to supply the area and reactivate the well pumps until the
replacement transformer arrived and was installed. Installation of the generators was
completed during the night shift on December 20, 2012. The well heat lamps were
turned on to thaw any frozen well water.
Immediately following confirmation that no frozen areas remained in the pumping
system, the well pumps were turned back on at approximately 3:00 pm on December 21,
2012.
As required by the O&M Plan, 24-hour verbal notification and a 5-day written
notification were provided to DRC. The 5-day written notification is included in Tab N.
5.5 Mass Removed
Chloroform removal was estimated as of the first quarter 2007. Since that estimation the
mass removed by well for each quarter has been compiled in Table 2, which shows the
pounds of chloroform that have been removed to date.
5.6 Inspections
EFRI has submitted an O&M Plan which includes a proposed weekly inspection form to
UDEQ for approval on October 25, 2010. Approval of that the O&M Plan was received
January 2, 2013. The inspection forms specified in the O&M Plan were implemented
during the first inspection conducted following the receipt of the DRC approval.
5.7 Conditions That May Affect Water Levels in Piezometers
There no water was added to the any of the wildlife ponds during the quarter.
6.0 CORRECTIVE ACTION REPORT
Necessary corrective actions identified during the current monitoring period are described
below.
Identification and Definition of the Problem
Chloroform is present in the rinsate blanks (TW4-21R and TW4-3R) and in the DIFB
(TW 4-60) for this quarter. A comparison of the rinsate blank sample concentration levels
21
N:\WMM\Required Reports\Chloroform Quarterly Monitoring Report\2012 Q4\2012_Q4Chloroform_Reporuext.doc
to the QAP requirements -that rinsate sample concentrations be one order of magnitude
lower than that of the actual well -indicated that one of the two rinsate blank analytes
met this criterion. Rinsate sample TW4-21R reported chloroform at 16.0 ug/L and
sample TW4-21 reported a chloroform concentration of 390 ug/L. The rinsate sample
TW4-21R is therefore compliant with the QAP requirements. Rinsate sample TW4-3R
had a reported detection of chloroform of 2.0 ug/L while chloroform was not detected in
sample TW4-3. The rinsate sample TW4-3R is not compliant with the QAP requirements
that the rinsate concentration be one order of magnitude lower than that of the actual
well.
While not required by the Chloroform QAP, DIFB samples are collected to analyze the
quality of the DI water system at the Mill, which is used to collect rinsate samples.
Because there is no requirement in the Chloroform QAP to collect a DIFB; there is no
requirement in the chloroform QAP for assessment of the DIFB. The DIFB is neither
compliant nor non-compliant with the Chloroform QAP requirements. The DIFB data
are collected and provided for information purposes only. The DIFB results are further
indicative of laboratory issues and these· results provide additional support for EFRI's
conclusion that Energy Laboratories are not providing the level of data review required
byEFRI.
Assignment of Responsibility for Investigation of the Problem
This problem has been investigated by the QA Manager.
Investigation and Determination of Cause of the Problem
A review of the analytical results reported for the DIFB sample indicated the sample
reported chloroform at 2.0 ug/L. Further review of the data package showed that the
DIFB sample as well as the rinsate sample TW4-21R were analyzed by the lab
immediately after samples with the high levels of chloroform. TW4-21R was analyzed
after a sample with a chloroform concentration of 708 ug/L, and TW4-60 was analyzed
after a sample with a chloroform concentration of 1200 ug/L. The detections in TW4-60
and TW4-21R are carry-over resulting from the samples analyzed previously. TW4-3R
was the first EFRI sample reported in the data package; however, it was not the first
sample analyzed on that instrument on that day and was most likely analyzed after a
sample with high concentrations of chloroform. The detection in TW 4-3R is carry-over
resulting from the samples analyzed previously. As analytical data from other clients is
confidential, EFRI cannot request the analytical data for the sample preceding TW 4-3R,
but based on the results from TW4-21R and TW4-60 carry-over is most likely the cause
of the detection of chloroform in TW 4-3.
Determination of a Corrective Action to Eliminate the Problem
Due to continued quality issues with Energy Laboratories, EFRI has changed laboratories
commencing with the first Quarter 2013 sampling event.
22
N:\WMM\Required Reports\Chloroform Quarterly Monitoring Report\2012 Q4\2012_Q4Chloroform_Report_text.doc
Assigning and Accepting Responsibility for Implementing the Corrective Action
It will be the responsibility of the QA Manager to review future rinsate blank and DIFB
data to assess results and determine if detections are present and investigate causes as
needed.
Implementing the Corrective Action and Evaluating Effectiveness
EFRI has contracted with another Utah-certified analytical laboratory that will provide
anal ytical services beginning with the first quarter 2013. The data will be reviewed for
compliance with the Chloroform QAP. If detections are compliant with the QAP
requirements, the corrective actions will be considered successful.
Verifying That the Corrective Action Has Eliminated the Problem
Verification that carryover is not causing erroneous detections will be completed upon
review of the analytical data from the first quarter of 2013.
6.1 Assessment of Previous Quarter's Corrective Actions
The third quarter 2012 report noted two corrective actions. Assessment of those
corrective actions is discussed below.
The issues which required corrective action from the third quarter 2012 are as follows:
TW4-24 receipt pH
Appendix A of the QAP states that all VOC samples are required to be preserved and
arrive at the laboratory with a pH less than 2. A review of the laboratory data for the third
quarter 2012 revealed that all VOC samples were received at the laboratory with a pH
less than 2 except for one, TW4-24.
Trip Blank Holding Times
One of the three trip blanks analyzed during the third quarter of 2012 was outside of the
required holding time. All other samples received with the trip blank were analyzed
within the required holding time and as such the data are not rejected. The samples
arrived at the laboratory with more than sufficient time to analyze all of the samples
within the required holding time, and therefore EFRI believes this to be a laboratory
error.
EFRI proposed specific corrective actions to address the above noted issues. However,
due to continued quality problems with Energy Laboratories, EFRI has contracted with
another Utah-certified laboratory. The corrective actions specified in the third quarter
2012 Chloroform report are no longer valid as those corrective actions were designed to
address issues which were caused by Laboratory error. EFRI believes that by contracting
with a new laboratory, the quality issues will be eliminated.

7.0 CONCLUSIONS AND RECOMMENDATIONS
The water level contour maps for the fourth quarter, 2012 indicate effective capture of
water containing high chloroform concentrations in the vicinity of pumping wells MW -4,
MW-26, TW4-19, and TW4-20. A well-defined capture zone is not evident at TW4-4.
The capture zone associated with TW4-4 is likely obscured by the low water level at
adjacent well TW 4-14 and the two orders of magnitude decrease in permeability south of
TW 4-4. However, the decrease in chloroform concentrations at TW 4-6 (located
down gradient of TW4-4) since the fourth quarter of 2009 is likely related to TW4-4
pumping.
Fourth quarter, 2012 chloroform concentrations at many of the wells with detected
chloroform were within 20% of the values reported during the previous quarter,
suggesting that variations are within the range typical for sampling and analytical error.
Changes in concentration greater than 20% occurred in wells MW-26, TW4-5, TW4-6,
TW4-18, TW4-19, TW4-20, TW4-22, and TW4-26; the concentration in well TW4-27
remained non-detect.
Of the wells showing changes in concentration greater than 20%, MW-26, TW4-19, and
TW4-20 are pumping wells. TW4-5 and TW4-22 are located adjacent to pumping well
TW4-20; TW4-18 is located adjacent to pumping well TW4-19; and TW4-6 is located
adjacent to pumping well TW 4-4. Fluctuations in concentrations at pumping wells and
wells adjacent to pumping wells likely result in part from changes in pumping. TW4-26
is located outside . of the chloroform plume near the down gradient edge of the plume.
Slight expansion and contraction of the chloroform plume boundaries in response to
changes in up gradient pumping are expected to impact the concentrations at TW4-26.
Between the current and previous quarters, the concentration in TW4-26, which is the
most down gradient temporary well, increased slightly from 4.9 ~glL to 5.9 ~glL. The
changes in concentrations at TW4-6 and TW4-26 are likely the result of their location
near the down gradient edge of the plume where changes in up gradient pumping are
expected to affect concentrations.
The highest chloroform concentration (19,000 ~glL) was detected at pumping well TW4-
20. Since the last quarter, the chloroform concentration in TW4-20 increased from
13,000 ~glL to 19,000 ~glL, the concentration in adjacent pumping well TW4-19
increased from 950 ~glL to 1,500 ~glL, the concentration in nearby well TW4-21
decreased slightly from 410 to 390 ~glL, and the concentration in nearby well TW4-22
decreased from 940 ~glL to 330 ~glL. Fluctuations in concentrations in these wells are
likely related to their location near the suspected former office leach field source area in
addition to variations in pumping in TW 4-20 and nearby wells. Regardless of these
measured fluctuations in chloroform concentrations, sampling of temporary wells TW 4-
24 (located west of TW4-22) and TW4-25 (located north of TW4-21), indicates these
wells remain outside the chloroform plume and thus bound the plume to the west and
north. Chloroform was not detected at TW4-25, and was detected at a concentration of
1.1 ~glL at TW4-24.
24
N:\WMM\Required Reports\Chloroform Quarterly Monitoring Report\2012 Q4\2012_Q4Chloroform_Reporuext.doc
The chloroform concentration at well TW 4-6 increased from 6.9 ~glL to 8.5 ~glL. This
well has been outside the chloroform plume boundary since the fourth quarter of 2010.
In the past, TW 4-6 has been both within and outside the plume. From the first quarter of
2009 through the fourth quarter of 2010, TW4-6 was within the plume. Prior to that time,
between the time of installation in the second quarter of 2000 and the fourth quarter of
2008, TW 4-6 was outside the plume. Although fluctuations in concentrations have
occurred, this well likely remained outside the plume between installation in 2000 and the
fourth quarter of 2008 due to a combination of 1) slow rates of down gradient chloroform
migration in this area due to low permeability conditions and the effe~ts of up gradient
chloroform removal by pumping, and 2) natural attenuation. The decreases in
concentrations at TW4-6 since the fourth quarter of 2009 are likely the result of
upgradient pumping, in particular pumping at adjacent well TW 4-4 (which commenced
in the first quarter of 2010). Chloroform remained non-detect at downgradient temporary
well TW4-23. TW4-23 and TW4-6 (with a chloroform concentration of 8.5 ~glL) bound
the chloroform plume to the south. TW4-8, TW4-12, TW4-13, TW4-14, and TW4-27
bound the chloroform plume to the east.
Continued pumping of MW-4, MW-26, TW4-19, and TW4-20 is recommended.
Pumping these wells, regardless of any short term fluctuations in concentrations detected
at the wells (such as at TW4-20), helps to reduce down gradient chloroform migration by
removing chloroform mass and reducing average hydraulic gradients, thereby allowing
natural attenuation to be more effective. Continued pumping at TW 4-4 is also
recommended to improve capture of chloroform to the extent practical in the southern
portion of the plume where low permeability conditions exist. The general decrease in
chloroform concentrations at TW4-6 from 1,000 ~glL to 8.5 ~glL since the first quarter
of 2010 is likely related to pumping at TW4-4. The decrease in the long-term rate of
water level rise at TW 4-6 since TW 4-4 pumping began, which suggests that TW 4-6 is
within the hydraulic influence of TW 4-4, is consistent with the decrease in chloroform
concentrations at TW 4-6.

Sample Delivery Group: C12100263 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 40C (±2OC)
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.

Sample Delivery Group: C12100576 CASE NARRATIVE
ORIGINAL SAMPLE SUBMITTAL(S)
All original sample submittals have been returned with the data package.
SAMPLE TEMPERATURE COMPLIANCE: 4ec (±2OC)
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.

MW-4, TW4-4, MW-26,TW4-19, and TW4-20 are contmually pumped wells.
TW4-02,tW4-03, TW4-06, TW4-07, TW4-1O, TW4-13, TW4--14, TW4-22, TW4-26,and TW4-27 were pumped dry and sampled after rycovery. .. .'-
RPD >10%. Per the revised QAP Revision 7.2, Attachment 2-3, when a well is purged to dryness, only pH, temperature and specific conductance parameters are required to be within 10% RPD. Redox potential and turbidity parameters are measured for information
purposes only and as such are not required to meet the 10% RPD criteria used for pH, specific conductance and temperature.
The QAP states that turbidity should be less than 5 Nephelometric Turbidity Units ("NTU") prior to sampling unless the well is characterize(j by water that has a higher turbidity. The QAP does not require that turbidi I measurements be less than 5 NTU
rior to samQling. As such, the noted observations regarding turbidi!y measurements less than 5 NTU are included for information ur oses ·. nly.

Re: White Mesa Uranium Mill-Notice of Violation and Corrective Action Order
UDEQ Docket No. UGW-20-01
Notice Pursuant to the Chloroform Pumping Well Operations and Maintenance Plan
Dear Mr. Lundberg:
Pursuant to the White Mesa Mill's (the "Mill's") Chloroform Pumping System Operations and
Maintenance Plan ("Chloroform O&M Plan") Energy Fuels Resources (USA) Inc., ("EFRI") as operator
of the Mill, is providing written Notice to the Utah Division of Radiation Control ("DRC") of a
temporary outage in two chloroform capture pumps, as described in more detail below.
The Mill's Chloroform Pumping O&M Plan states that EFRI will notify DRC of system failures that
cannot be made operational within 24 hours of discovery. It was determined on Wednesday, December
19, 2012 that a transformer failure had occurred which would require more than 24 hours to be repaired.
The failure shut down electrical power to two chloroform continuous pumping wells which will be off
(not pumping) until the transformer is replaced or an interim source of power is provided. Initial notice
of this outage was given by telephone to Mr. Dean Henderson of DRC at approximately 3 :40 pm on
Wednesday December 19,2012 (within 24 hours of the discovery).
1. Description of the Pumping System Failure
a) The Mill's Chloroform O&M Plan, submitted on October 25, 2010 and currently under review
by UDEQ, states that Denison will notify UDEQ of system failures that cannot be "repaired
and fully made operational within 24 hours of discovery."
b) The Mill experienced freezing temperatures for most of the week of December 17, 2012.
Temperatures reached single digits on December 19,2012.
Letter to Rusty Lundberg
December 21,2012
Page 2 of4
c) One of the power circuits to the Cell 1 area supplies power to MW-26 and TW4-20. This
circuit includes a transformer near the Mill's truck shop.
d) Mill personnel discovered, at approximately 10:30 am on December 19, 2012, that the truck
shop transformer had failed when power to several areas of the Mill, including the tailings
area, failed.
e) MW-26 and TW4-20 pumps stopped when power was lost. There was no apparent damage to
the pumps or flow measurement instrumentation; however pumping will cease until power can
be restored to the affected circuit.
f) During the morning of December 20, 2012, Mill management determined that a replacement
for the damaged transformer would require up to 2 weeks or longer for delivery to the Mill
site.
g) On December 20, 2012, Mill management began moving gasoline driven generators to supply
the Cell 1 area and reactivate the well pumps until the replacement transformer arrives and is
installed. Installation of the generators was completed during the night shift on December 20,
2012. The well heat lamps were turned on to thaw any frozen well water.
h) Immediately following confirmation that no frozen areas remained in the pumping system, the
well pumps were turned back on at approximately 3 :00 pm on December 21, 2012.
2. Root Cause
The root cause analysis is as follows:
a) A failed transformer caused a loss of power to the circuit which includes MW-26 and TW4-
20.
b) The replacement transformer could not be acquired and installed within 24 hours of the initial
power loss.
c) The installation of the temporary generator and thawing of the well pIpIng prior to
resumption of pumping required longer than 24 hours.
3. Period of Time the System Was Not in Operation
At the time of writing of this Notice, the pumps ceased operation for approximately 54 hours from
December 19 to 21, 2012.

Page 3 of4
4. Date By Which the Pumping System Will Be Repaired and Operational
Pumping was resumed on December 21,2012.
5. Steps taken to Repair and Have the System Fully Operational
a) Mill maintenance personnel isolated the failed electrical circuits on December 19,2012.
b) Mill maintenance personnel located on site several portable gasoline-driven electric
generators throughout the day on December 20,2012.
c) Two generators were placed at the Cell 1 area on December 20,2012. One generator was
wired to supply both of the affected pumping well pump motors.
d) Maintenance personnel set up the heat lamps to thaw any potential frozen piping around the
two affected well pumps.
e) The two affected well pumps were turned on and resumed pumping at approximately 3 :00
pm on the morning of December 21,2012.
f) The portable generator supplying the two affected well pumps will be left in place until the
replacement transformer arrives, is installed, and power is restored to the Cell 1 area
electrical circuit.
6. Additional Factors to Be Taken into Account
Although this incident does not fall within U AC R317 -6-6.16, EFRI believes that the following should
be taken into account by DRC in evaluating this incident.
a) Notification
By virtue of the initial oral notification given to DRC at 3:40pm on Wednesday December 19, 2012
(within 24 hours of the discovery) and this written notice, EFRI has submitted notification according
within five days.
b) Failure was not Intentional or Caused by EFRI's Negligence
The failure of the pumping system was not due to negligence on the part of EFRI or Mill personnel.
The failure resulted from an unavoidable condition, specifically, failure of a transformer occurring
during continued freezing weather.
c) EFRI has Taken Adequate Measures to Meet the Conditions of the Chloroform 0 & M Plan
EFRI has taken adequate measures to meet Permit conditions in a timely manner. Mill personnel
notified Corporate Compliance personnel within hours of the incident. DRC was notified on the same
Letter to Rusty Lundberg
December 21, 2012
Page 4 of4
day as the incident, and within 24 · hours. Mill personnel immediately located and ordered a
replacement transformer. Mill personnel located and moved temporary generators to the Cell 1 and
well pump area within hours of determining that delivery time for the replacement transformer.
Hookup of the generator for the two affected pumps, thawing of the line, and restart of the well pumps
was performed within less than three days from the initial power loss.
d) The Provisions ofUCA 19-5-107 Have Not Been Violated
The provisions of Utah Code 19-5-107 have not been violated. There has been no discharge of a
pollutant into waters of the state. EFRI has not caused pollution which constitutes a menace to public
health and welfare, or is harmful to wildlife, fish or aquatic life, or impairs domestic, agricultural,
industrial, recreational, or other beneficial uses of water, nor has EFRI placed or caused to be placed
any waste in a location where there is probable cause to beli~ve it will cause pollution.
If you have any questions, please contact me at [phone].
Yours very truly,
