Re: State of Utah Ground Water Discharge Permit No. UGW370004
White Mesa Uranium Mill - Notice Pursuant to Part I.G.I (a)
Dear Mr. Lundberg:
The White Mesa Mill (the "Mill") performed third quarter ("Q3") groundwater monitoring during the
period from July 1, to September 30, 2014 under the August 24, 2012 version of the Mill's Groundwater
Discharge Permit (the "GWDP"). All analytical data needed for comparison to the GWCLs were
received during the period ending October 17, 2014.
Pursuant to Part I.G.I.a) of the GWDP, (August 24, 2012) please take notice that the concentrations of
specific constituents in the monitoring wells highlighted in yellow and bold italics in the columns for this
quarter in the attached Table 1 exceeded their respective GWCLs. For ease of review, Table 1 has been
formatted to simplify the tracking of any continued exceedances from one monitoring period to the next
by charting ongoing monitoring of the same well in the same row, and by highlighting exceedances (in
color and bold italics).
Part I.G. 1 c) of the GWDP states "that the Permittee shall prepare and submit within 30 calendar days to
the Executive Secretary a plan and a time schedule for assessment of the sources, extent and potential
dispersion of the contamination, and an evaluation of potential remedial action to restore and maintain
groundwater quality to ensure that Permit limits will not be exceeded at the compliance monitoring point
and that DMT or BAT will be reestablished." The summary below relating to Q3 2014 exceedances
includes, for each exceedance, a brief discussion of whether such a plan and schedule is or is not required
or appropriate at this time in light of other actions currently being undertaken by Energy Fuels Resources
(USA) Inc. ("EFRI") or in light of other reports submitted by EFRI, and as determined by Division of
Radiation Control ("DRC") Staff. A description of the other actions and reports which have affected the
requirement to submit a plan and time schedule are as follows:
1. Nitrate + nitrite and chloride in monitoring wells at the site have been the subject of ongoing
investigations at the Mill. Based on the results of the previous investigations, EFRI and the
Director acknowledge that it has not been possible to date to determine the source(s), cause(s),
attribution, magnitudes of contribution, and proportion(s) of the local nitrate + nitrite and chloride
in groundwater. EFRI submitted a Corrective Action Plan ("CAP") in February 2012 for nitrate
+ nitrite and chloride in groundwater. The CAP was approved on December 12, 2012 and the
activities associated with the CAP are on-going. Based on information provided by DRC in
teleconferences on April 27, and May 2, 2011, due to the ongoing activities and actions, the 30-
Letter to Mr. Rusty Lundberg

day plan and schedule for assessment is not required for nitrate + nitrite and chloride exceedances
at this time.
2. As discussed in previous quarterly groundwater sampling reports, the background levels and
GWCLs for pH were established based on eight or more quarters of laboratory data, which are
historically higher than field data. EFRI's letter to the Director dated January 31, 2011 proposed
the recalculation of the GWCLs for field pH. Following the statistical evaluation of pH data by
EFRI's geochemical consultant, ENTERA, Inc., EFRI compared the Mill's groundwater pH data
from Q2 2011 and noted that all of the June 2011 groundwater results, and many of the other
results from Q2 2011, were already outside the revised GWCLs that were to be proposed in the
June 30, 2011 letter. Pursuant to teleconferences with DRC on December 5, and December 19,
2011, EFRI submitted a Work Plan and Schedule on January 20, 2012 and a revised plan based
on DRC comments on April 13, 2012. Based on the approved Work Plan and Time Schedule,
EFRI and DRC entered into a Stipulated Consent Agreement ("SCA") dated July 12, 2012. The
SCA required the completion of the pH Report and the Pyrite Investigation and associated report.
The pH Report and Pyrite Investigation Report were submitted November 9, 2012 and December
7, 2012 respectively. By letter dated April 25, 2013, DRC accepted the conclusions that the out-
of-compliance results for pH are due to background effects within the aquifer matrix and are not
caused by Mill activities. DRC also approved the recalculation of the GWCLs. As a result, the
30-day plan and schedule for assessment is not required for field pH exceedances.
3. A Plan and Time Schedule will not be prepared for monitoring wells with two successive
exceedances in Q3 2014 if successive exceedances were reported in a previous quarter and were
included in the Source Assessment Reports ("SARs"), submitted October 10, 2012, May 8, 2013,
August 30, 2013, December 17, 2013, January 13, 2014, and March 19, 2014. A Plan and Time
Schedule will not be submitted for those constituents covered by the previously mentioned SARs,
because the conclusions and actions delineated in those reports were either accepted by DRC as
documented in DRC correspondence dated April 25, 2013, July 23, 2013, September 17, 2013
January 7, 2014, March 10, 2014, and June 5, 2014 respectively.
4. Chloroform and methylene chloride are the subject of the ongoing chloroform pumping program
and are covered by 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. As a result, the 30-day plan and schedule for assessment of chloroform and
methylene chloride exceedances is not required.
It is important to note that under the GWDP, GWCLs have been determined on a well-by-well basis to
reflect background groundwater quality, as defined by the mean plus second standard deviation
concentration, or the equivalent. Accordingly, the GWDP requires that constituent concentrations in each
monitoring well shall not exceed the GWCLs set out in Table 2 of the GWDP. It should be noted that,
because the GWCLs have been set at the mean plus second standard deviation, or the equivalent, un-
impacted groundwater would normally be expected to exceed the GWCLs approximately 2.5% of the
time. Therefore, exceedances are expected in approximately 2.5% of all sample results, and do not
necessarily represent impacts to groundwater from Mill operations. In fact, more frequent sampling of a
given analyte will increase the number of exceedances due to statistical variation and not due to Mill
activity. Additionally, given the slow velocity of groundwater movement, accelerated sampling at a
monthly frequency can result in resampling of essentially the same water and can lead to repeat
exceedances for accelerated constituents not due to Mill activities, but due to repeat sampling of the same
water.

1.0 Exceedances in Required Quarterly Sampling Wells
1.1 Quarterly Wells with Two Successive Exceedances
As indicated in the attached Table 1, the analytes discussed below exceeded their respective GWCLs for
two successive sampling periods in Q3 2014. The 30-day plan and schedule contemplated in Part I.G.I c)
of the GWDP will be required for the consecutive exceedance of uranium in MW-28 as discussed below.
The 30-day plan and schedule contemplated in Part I.G.I c) for the remainder of the consecutive
exceedances which occurred in Q3 of 2014, will not be required for the reasons stated below. One-time
exceedances and non-successive exceedances are noted on Table 1, but not listed below. Consecutive
exceedances which occurred in previous reporting periods are discussed in the SARs submitted to DRC
October 10, 2012, May 8, 2013, August 30, 2013, December 17, 2013, January 13, 2014, and March 19,
2014.
MW-11
• Manganese concentrations exceeded the GWCL in MW-11 in the July and August monthly
sampling events. This consecutive exceedance is addressed in the SAR, dated October 10, 2012.
As a result of the SAR, the GWCLs have been recalculated and accepted by DRC. The
recalculated GWCLs will become effective upon their publication in the next revision of the
GWDP. As a result of DRC's acceptance of the recalculated GWCLs, a plan and schedule to
address this consecutive exceedance is not necessary and will not be submitted. Until such time as
the new GWCLs become effective, the exceedances will continue to be noted and reported.
MW-26
• Nitrate + nitrite has exceeded its GWCL in all of the Q3 2014 sampling events. As mentioned
above, a CAP has been submitted and approved and the specified actions are currently being
implemented; therefore a plan to address this consecutive exceedance is not necessary and is not
being submitted.
• Chloroform has exceeded its GWCL for all of the Q3 2014 sampling events. MW-26 is used as a
pumping well for the ongoing chloroform capture program and is expected to yield increased
concentrations of chloroform. Because this well is used in the chloroform capture program
which is the subject of separate investigations and actions, a plan and time schedule to address the
consecutive exceedances is not necessary and is not being submitted.
• Methylene chloride has exceeded its GWCL for all of the monitoring periods for Q3 2014. MW-
26 is used as a pumping well for the ongoing chloroform capture program and is expected to yield
increased concentrations of methylene chloride. Because this well is used in the chloroform
capture program which is the subject of separate investigations and actions, a plan and time
schedule to address the consecutive exceedances is not necessary and is not being submitted.
MW-26 Note: As stated in the September 2009 Statement of Basis (page 23) in support of the January
20, 2010 revisions to the GWDP, "[i]t should be noted that, because MW-26 is a pumping well for
chloroform removal, concentrations of all constituents in that well are subject to potential variation over
time as a result of the pumping activity. This will be taken into account by the Executive Secretary in
determining compliance for this well." Based on information provided by DRC in teleconferences on
April 27, and May 2, 2011, due to the current pumping status as part of the chloroform investigation
program, the 30-day plan and schedule for assessment is not required at this time for exceedances of
chloroform and methylene chloride in MW-26.

• Thallium has exceeded the GWCL for both the Q2 2014 sampling event and the Q3 2014
sampling event. This consecutive exceedance is addressed in the SAR, dated October 10, 2012.
In the October 10, 2012 SAR, EFRI requested the removal of GWCLs for the far upgradient wells
(MW-1, MW-18, and MW-19) at the Mill which cannot be impacted by Mill activities. In
correspondence dated April 25, 2013, DRC noted "DRC agrees with the justification provided by
EFR, that far upgradient wells are not likely to be impacted by current Mill activities..." and has
recommended the removal of GWCLs for MW-18 from the next revision of the GWDP. A plan
and schedule is not necessary because the exceedance is not caused by Mill activities and was
previously discussed in the October 10, 2012 SAR. Until such time as the GWCLs are removed,
the exceedances will continue to be noted and reported.
MW-24
• Field pH has been slightly outside (slightly lower than) the GWCL for both the Q2 2014 sampling
event and the Q3 2014 sampling event. As mentioned above, site-wide pH issues and trends are
addressed in reports submitted on November 9, 2012 and December 7, 2012. As a result of the
November 7, 2012 report, the GWCLs have been recalculated and accepted by DRC. The
recalculated GWCLs will become effective upon their publication in the next revision of the
GWDP. As a result of DRC's acceptance of the recalculated GWCLs, a plan and schedule to
address this consecutive exceedance is not necessary and will not be submitted. Until such time as

plan and schedule for assessment will be submitted under separate cover within 30 days of this
Exceedance Notice.
• Gross Alpha has exceeded the GWCL for both the Q2 2014 sampling event and the Q3 2014
sampling event. This consecutive exceedance is addressed in the SAR, dated January 13, 2014.
As a result of the SAR, the GWCLs have been recalculated and accepted by DRC. The
recalculated GWCLs will become effective upon their publication in the next revision of the
GWDP. As a result of DRC's acceptance of the recalculated GWCLs, a plan and schedule to
address this consecutive exceedance is not necessary and will not be submitted. Until such time as
the new GWCLs become effective, the exceedances will continue to be noted and reported.
2.1 Semi-annual Wells with New Exceedances Reported in Q3
One new exceedance for the Q3 2014 semi-annual well sampling program is listed below. This
exceedance will result in an accelerated sampling frequency from semi-annually to quarterly. It is
important to note that the well listed below will only be sampled during the first and third quarterly events
for the constituent which exceeded the GWCL. The well listed below will be sampled for all constituents
listed in the GWDP during the second and fourth quarterly events as that is the regularly scheduled
sampling for the semi-annual wells.
• Field pH in MW-1 was below the GWCL in the Q3 sampling event.
Relative to accelerated reporting requirements, based on phone conversations with UDEQ on April 5,
2010, reporting of exceedances is required to be completed within 30 days of receipt of the last data
package for a quarterly monitoring event. Similarly, accelerated monitoring is required to commence the
month following the submission of the Exceedance Notice for a specified quarter for wells that are being
accelerated from quarterly to monthly and the quarter following the submission of the Exceedance Notice
for wells that are being accelerated from semiannually to quarterly. Per teleconferences with UDEQ,
EFRI proposed modified language for the GWDP, Part l.G.l on May 25, 2012, to document DRC
concurrence with the accelerated reporting and monitoring agreements resulting from the April 5, 2012
teleconference.
