Henderson IT'/Sl&
SUBJECT: Review of the November 13, 2015 Annual Seeps and Springs Sampling Report for Energy
Fuels Resources (USA), Inc. White Mesa Uranium Mill, near Blanding, Utah
On November 13,2015 the Division of Waste Management and Radiation Control (“DWMRC”) received
the 2015 Annual Seep and Springs Sampling Report (“Report”) [eDocs: DRC-2015-008129] for the
Energy Fuels Resources (USA), Inc. (“EFR”) White Mesa Uranium Mill (“Mill”), near Blanding, Utah.
For the review of this Report the following regulatory enforcement documents will be used:
• White Mesa Uranium Mill Ground Water Quality Assurance Plan (“QAP”).
Revision 7.2, dated June 6,2012.
• Groundwater Discharge Permit No. UGW370004 (“Permit”). Permit version that was signed on
August 24, 2012.
• Sampling Plan for Seeps and Springs In the Vicinity of the White Mesa Uranium Mill. Revision 0.
(“Plan”).
• Utah Department of Environmental Quality Division of Radiation Control Guidance for
Groundwater Split Sample Collection at Uranium Mill Operations. August 7,2007.
Summary of Compliance
EFR informed the DWMRC in a letter dated June 2,2015, that EFR would be sampling the seeps and
springs on June 16, 2014 (eDocs: DRC-2015-002622). EFR letter was one day late in providing a 15 day
notice prior to sampling as required in Section 3 of the Plan. However, in an e-mail on March 30,2015
DWMRC staff Dean Henderson requested EFR to schedule the 2015 seeps and springs sampling event on
June 16, 2015. On the same day EFR staff responded by email confirming the June 16, 2015 seeps and
spring sampling date (see email in Attachment 2). Therefore, this e-mail document will be used to meet 15
day notice prior to sampling as required in Section 3 of the Plan.

The Plan requires the Report to be submitted to the DWMRC on or before December 1 of each year. The
Report was received by the DWMRC on November 17, 2015, which met the Plan requirement.
The Report met all of the following reporting requirements in Section 6 of the Plan:
1) Document the sampling event by means of providing the field sheets recorded at the time of
sampling.
2) Copies of all field measurements and laboratory results.
3) Provide a water table contour map that includes a water table elevation of all groundwater
monitoring wells at the facility (3rd quarter 2014 water level measurements) and the elevations of
the phreatic surface observed at each of the seep and springs sampled.
4) Provide an evaluation and interpretation of the groundwater quality data collected.
The DWMRC staff also observed the EFR staff sample Cottonwood Spring, Entrance Spring, Ruin Spring,
and Westwater Spring (see photographs in Figures 1-4). It should be noted that the water sample for
Westwater Spring may be water from resent rain storm event (within the last 48 hours). Coral Canyon and
Corral Seep were found to be dry and therefore no sample could be collected.
DWMRC Staff observed the EFR staff perform the sampling and monitoring on June 16,2015 and after the
DWMRC review of the Report, it appears that EFR appropriately followed the QAP and Plan.
Duplicate Sample Comparison
Historic DWMRC seeps and springs sample analytical results are summarized in Table 6 in Attachment 1
below. Comparisons of duplicate samples analytical results are summarized in Tables 7 and 8 in
Attachment 1 below. To determine if sample results between two samples from the same laboratory are
comparable, a relative percent difference (“RPD”) of 20% is acceptable (DRC 2007). To determine if
sample results between two samples from two different laboratories are comparable a RPD of 30% is
acceptable (DRC 2007). For radiologies, to determine if sample results between two samples or two
laboratories are comparable, a replicate error ratio (“RER”) of < 2 is acceptable (DRC 2007).
EFR Duplicate Sample Comparison
EFR collected a duplicate of Entrance Spring and identified it as “Back Spring”. The RER comparisons for
gross alpha < 2. The RPD comparisons between the analytical results were below 20% with the exception
of the analytical result for ammonia, (see Table 8). The analytical result for ammonia for Entrance Spring
and Back Spring was 0.202 mg/1 and 0.139 mg/1 respectively. The resulting RPD was of 37 %. Since
concentration results are well below the GWQS for ammonia (25 mg/1) as found in Table 2 of the Permit
no actions are recommenced.
DWMRC Duplicate Sample Comparison
The DWMRC collected a split sample of Cottonwood Spring with EFR. The DWMRC also collected a
duplicate of this spring and identified it as “Spring 1”. The RER comparisons for gross alpha was < 2. The
RPD comparisons between the analytical results were found below 20% with the exception of the
analytical results for acetone and dichloromethane (or methylene chloride) [see table 7]. The analytical
result for acetone for Cottonwood Spring and Spring 1 was 4pg/l and 3.1 pg/1 respectively having a RPD of
25%. The analytical result for dichloromethane for Cottonwood Spring and Spring 1 was 2.9pg/l and
1.6pg/l, respectively, having a RPD of 58%. Acetone and dichloromethane are below the GWQS of
Page 3
700|ig/l and 5pg/l respectively found in Table 2 of the Permit. Recommenced actions for detectable VOCs
are addressed below. The remainder of the analytical results are comparable.
DWMRC Sample Comparison To EFR
The RPD comparison between the analytical results found on Table 7 for the DWMRC Cottonwood Spring
and Spring 1 sample and EFR Cottonwood Spring sample were below 30% with the exception of the
analytical results for sodium, potassium, and calcium (see table 7). The analytical result for sodium for
DWMRC Cottonwood Spring and Spring 1 was 230 mg/1 and 250 mg/1 respectively and for EFR
Cottonwood Spring was 126 mg/1. The resulting RPDs was of 58% and 66% respectively. There is no
GWQS for sulfate in the Permit therefore, no actions are recommenced. The analytical result for potassium
for DWMRC Cottonwood Spring and Spring 1 was 5.7 mg/1 and 6.1 mg/1 respectively and for EFR
Cottonwood Spring was 3.14 mg/1. The resulting RPDs was of 58% and 64% respectively. There is no
GWQS for potassium in the Permit therefore, no actions are recommenced. The analytical result for
calcium for DWMRC Cottonwood Spring and Spring 1 was 92 mg/1 and 100 mg/1 respectively and for
EFR Cottonwood Spring was 162 mg/1. The resulting RPDs was of 55% and 47% respectively. There is no
GWQS for calcium in the Permit therefore, no actions are recommenced. The remainder of the analytical
results are comparable.
The RER comparison between the gross alpha analytical results found on Table 7 for the DWMRC
Cottonwood Spring and Spring 1 sample and EFR Cottonwood Spring sample were greater than 2. The
analytical result for manganese for DWMRC Entrance Spring and Spring 1 was 4.59±1.98 pCi/1 and
4.27±2.1 pCi.l respectively and for EFR Cottonwood Spring was 0.0198±0.112. The resulting RERs was
of 2.49 and 2.07 respectively. Since all three concentration results are well below the GWQS for gross
alpha (15 pCi/1) as found in Table 2 of the Permit no actions are recommenced.
Mill Operations Impact on the Seeps and Springs.
The analytical results for the 2015 seeps and springs monitoring event are summarized in tables 1 through
5 in Attachment 1 below. Photographs in figures 1-4. As stated above Coral Canyon and Corral seeps
were found to ether dry or not enough moisture to collect a water sample.
Cottonwood Spring
The only metal detected was uranium and it did not exceed its GWQS. Also, the uranium concentration
was typical of historic concentrations. Gross alpha was below GWQS. No VOCs were detected in EFR
sample. However, for the first time since annual sampling began in 2009, VOCs acetone and
dichloromethane (or methylene chloride) were detected in the DWMRC samples for Cottonwood Spring
and its duplicate sample Spring 1. The acetone concentration for Cottonwood Spring and Spring 1 was 4
jj.g/1 and 3.1 pg/1, respectively, and were below the GWQS (700 pg/1). The dichloromethane concentration
for Cottonwood Spring and Spring 1 was 2.9 pg/1 and 1.6 pg/1, respectively, and were below the GWQS (5
pg/1). Recent rain storms may have impacted Cottonwood springs (within last 48 hours). At this time it is
difficult to determine the VOC(s) source. Should the 2016 sampling data show that VOC(s) continue to be
detected DWMRC Director may require an increase in sampling frequency or other actions to determine
possible sources that may have an impact on Cottonwood Spring.
A comparison of the 2009, 2010, 2011, 2012,2013 and 2014 data to the 2015 data shows that the
concentrations of most detected analytes remained approximately the same. Overall, the data reported for
Cottonwood Spring water appear to show no indication of Mill impact. Photograph in figures 2.
Page 4
Entrance Spring
Some metals were detected and were below their GWQS with the exception of uranium (36pg/l) [see Table
1]. In 2013 uranium also exceeded the GWCL (30pg/l) and since the 2009 monitoring event it appears that
uranium concentrations are increasing (see table 3). Should the 2016 sampling data show uranium
exceeding the GWQS the DWMRC Director may require an increase in sampling frequency or other
actions required to determine possible sources that may have an impact on Entrance Spring.
No VOCs were detected and gross alpha was below GWQS. A comparison of the 2009, 2010, 2011, 2012,
2013 and 2014 data to the 2015 data shows that the concentrations of most detected analytes remained
approximately the same. All other data reported for Entrance Spring water appear to show no indication of
Mill impact. Photograph in figure 1.
Ruin Spring
The only metals detected were Molybdenum, selenium, silver and uranium. None exceeded GWQS. No
VOC detected and gross alpha was below GWQS. Major ions were detected. A comparison of the 2009,
2010,2011,2012,2013 and 2014 data to the 2015 data shows that the concentrations of most detected
analytes remained approximately the same. Overall, the data reported for Ruin Spring water appear to
indicate no indication of Mill impact. Photograph in figure 3.
Westwater Spring
The only metals detected were manganese and uranium. None exceeded GWQS. No VOCs were detected
and gross alpha was below GWQS. Major ions were detected. It should be noted that the water sample for
Westwater Spring may be water from recent storm event (within the last 48 hours). Overall, the data
reported for Ruin Spring water appear to indicate no indication of Mill impact. Photograph in figure 4.
Conclusion on Report
Based on the review of the Report requirements appear to satisfy the Permit, QAP, and Plan requirements
and at this time no further action is required of EFR.
