EXHIBIT EXHIBIT A Supporting Documentation Shootaring Canyon 1st 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 January 1, 2013 through June 30, 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 first half of 2013 were March 14th through March 15th and May 20th through May 21st. 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 49.6 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 4.24 x 109 ml. The average flow rate was 1.40 x 106 ml/minute (49.6 cfm). The total sampling time was 3,018.1 minutes (50.3 hours). The results of the sample analyses are given in the following table: Air Sample Composite Results Radionuclide Concentration (µCi/ml) Error Estimate (µCi/ml) Lower Limit of Detection (µCi/ml) % Effluent Concentration Limit U-nat 1.28 x 10-16 N/A 2.0 x 10-17 0.1 Ra-226 1.56 x 10-16 5.70 x 10-17 2.60 x 10-17 0.017 Shootaring Canyon 1st Half 2013 Effluent Report 2 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 0.24 pCi/filter (5.7 x10-17 µCi/ml) for the first 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. First quarter 2013 sampling was performed on February 19th. Second quarter 2013 sampling was performed on May 13th and 21st. 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 first half of 2013. Results of the ground water sample analyses will be submitted with the Semi-Annual Ground Water Monitoring report under separate cover. Shootaring Canyon 1st Half 2013 Effluent Report 3 5.0 DISCUSSION OF RESULTS No airborne effluent concentration limits or groundwater threshold values were exceeded in the first 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.
