Shootaring Canyon 2nd Half 2013 Effluent Report 1

1.0 INTRODUCTION

The following Effluent Monitoring Report is presented to comply with Utah Department
of Environmental Quality, Division of Radiation Control requirements (UAC R313-24-
3), 10 CFR 40.65, and License Conditions 11.3 and 12.2 of Byproduct Material License
#UT0900480. The current Licensee is Uranium One Americas, Inc.

The sampling data represent the period from July 1, 2013 through December 31, 2013 for
the Shootaring Canyon Mill. License requirements reflect the current standby status of
the mill.

2.0 AIR SAMPLING

The license requires one 20-hour to 24-hour sampling period each calendar quarter with
the filters composited and analyzed for U-nat and Ra-226 on a semi-annual basis
(License Condition 11.2, Table 5.5-8). The dates of collection during the second half of
2013 were July 23rd through July 24th and November 6th through November 7th. The
sampler (AP-3) is located downwind of the tailings facility. Supporting documentation
for this report is attached as Exhibit A.

The samples were obtained using a Graseby/GMW high volume air particulate sampler
with an average flow rate of 49.9 cubic feet per minute (cfm). The sampler flow
indicator was calibrated prior to each quarterly sampling period using a series of orifice
plates and an antifreeze-filled manometer. The manometer readings were converted to
actual flow rates using a standard calibration curve. A graph of actual flow rate versus
indicated flow rate was constructed. The actual flow rate for the sampling period was
taken from the graph. The flow rate was multiplied by the elapsed time to obtain the
volume of air sampled for each of the two sampling periods. The volumes were added to
obtain the total semi-annual sample volume.

The total volume sampled for the two quarterly periods was 4.17 x 109 ml. The average
flow rate was 1.41 x 106 ml/minute (49.9 cfm). The total sampling time was 2,954.80
minutes (49.25 hours).

The results of the sample analyses are given in the following table:

3.0 SUPPLEMENTAL NOTES

a. The % Effluent Concentration Limit column for the air sample results refers to the 10
CFR 20, Appendix B, Table 2, Effluent Concentration Limits for unrestricted areas.

Nuclide Effluent Concentration Limit
for Air
(µCi/ml)
Effluent Concentration Limit
for Water
(µCi/ml)
U-nat, Class Y 9 x 10-14 3 x 10-7
Ra-226 9 x 10-13 6 x 10-8

b. The airborne particulate sampler is operated for a minimum of 20 hours (1200 minutes)
each calendar quarter. The two quarterly samples are digested together for a total semi-
annual analysis.

c. The filters were analyzed by ALS located in Fort Collins, Colorado. The laboratory
reports concentrations, estimated uncertainties, lower limit of detection, and percent of
the Effluent Concentration Limit. Error limits (uncertainties) for Ra-226 were 0.26
pCi/filter (6.2 x10-17 µCi/ml) for the second half 2013 air sample results. Error limits are
not reported for U-nat analyses.

4.0 GROUNDWATER MONITORING WELLS

The radioactive materials license condition 11.3A requires the following wells to be
sampled on a semi-annual basis: RM-1, RM-2R, RM-7, RM-12, RM-14, RM-18, and
RM-19. RM-1 and RM-12 are the up gradient monitoring wells and represent the site
background. Uranium One has voluntarily sampled wells RM-8 and RM-20 and reports
these data semi-annually. Quarterly samples are collected as part of the on-going
accelerated background monitoring program as per Ground Water Quality Discharge
Permit UGW170003. Groundwater samples are collected from monitoring wells
following the Groundwater Quality Assurance Plan for the site.

Third quarter 2013 sampling was performed on July 15th. Fourth quarter 2013 sampling
was performed on November 5th.

License Condition 11.3 B references the standards in the Utah Administrative Code
(UAC) R313-24-4. This section of the UAC references the Code of Federal Regulations
(CFR), specifically 10 CFR Part 40, Appendix A but explicitly replaces Criterion 5B(1)
through 5H, which includes the ground water protection standards, with the ground water
standards in UAC R317-6. No constituents in the approved monitoring program
exceeded any of the Ground Water Quality Standards in Table 1 of the Ground Water
Discharge Permit (R317-6-2) in the second half of 2013. Results of the ground water
sample analyses will be submitted with the Annual Ground Water Monitoring report
under separate cover.

5.0 DISCUSSION OF RESULTS

No airborne effluent concentration limits or groundwater threshold values were exceeded
in the second half of 2013. A review of current and past data does not reveal any
confirmed trends as results are near analytical lower limits of detection and currently
<1% of the effluent concentration limits listed in 10 CFR 20, Appendix B Table 2 for air
and groundwater limits are within the magnitude of the random variations that have been
historically observed in the ground water data.
