The report must specify the quantity of each of the principal radionuclides released to unrestricted areas in liquid and in gaseous effluents during the previous six months of operation. 1. Did the licensee submit the report within 60 days of the end of the reporting period i.e., January 1 st or July 1st? (10CFR40.65(a)(1)) Yes No Comments: The Semi-Annual Effluent Monitoring Report for the 2" half of 2016 for the White Mesa Mill was submitted on February 21, 2018 Page 1 of 8 2. Were the stack samples analyzed for U-nat, 230Th, 226Ra and 210Pb? (NRC Reg Guide 4.14) and Th- 228, Th-232 and Ra-228 (L.C. 11.9) Yes Z No El Comments: Stack sampling occurred only during quarters when the stack was operated. 3. Were site boundary effluent air samples analyzed for U-nat, 230Th, 226Ra and 210r — b (NRC Reg Guide 4.14) and Th-232 (L.C. 11.9) Yes No El 10CFR20 Appendix B Table 2 first paragraph states "The columns in Table 2 of this appendix captioned "Effluents," "Air," and "Water," are applicable to the assessment and control of dose to the public, particularly in the implementation of the provisions of sC 20.1302. The concentration values given in Columns I and 2 of Table 2 are equivalent to the radionuclide concentrations which, i f inhaled or ingested continuously over the course of a year, would produce a total effective dose equivalent of 0.05 rem (50 millirem or 0.5 millisieverts)." Comments: Sampling results were below ECLs for all analyzed isotopes at all monitoring locations for the last four quarters, and for the year. See the attached Particulate, Radon and Gamma Screening analysis for a summary of quarterly and annual data and a calculated dose at each of the high-volume air stations. Page 2 of 8 230Tb, 226Ra and 4. Were the site boundary effluent air sample results within applicable limits for U-nat, 210pb?

Did the results of the effluent monitoring for this reporting period achieve the site's ALARA objective of 25% of the ECL's? (2007 License Renewal Application Vol. 1 Section 6.5; 10CFR20 Table II of Appendix B) 10CFR20 Table II of Appendix B, ECL's: U-nat .9.0E14 µCi/m1 in air.....25% = 2.25E14 p.Ci/m1 in air 230Th 2.0E141.1Ci/m1 in air.....25% = 5.15E15 µCi/m1 in air 226Ra 9.3E13 µCi/m1 in air.....25% = 2.33E13 µCi/ml in air 210pb 6 0E13 µCi/ml in air.....25% = 1.50E13 µCi/ml in air Yes Z No 0 Comments: See the attached Particulate, Radon and Gamma Screening analysis for a summary of quarterly and annual data and a calculated dose at each of the high-volume air stations. The summary compares total dose to the mill's ALARA goal and to the annual 100 mrem exposure limit. 230Tb 226Ra 21opb Page 3 of 8 6. Were Gamma Measurements (Minus Background) Collected at each Monitoring Station? Comments: BHV-1 and BHV-5 exceed the gamma limits in 40CFR190 of 25 mrem but were less than the gamma limits in R313-15-301 (10CFR20.1301) of 100 mrem for the general public dose for the last four quarters. BHV-1 and BHV-5 both exceeded the 25 mrem for 2015. Need to monitor to see if they go back down in 2016. See the attached Particulate, Radon and Gamma Screening analysis for a summary of quarterly and annual data and a calculated dose at each of the high-volume air stations. 7. Were soil samples analyzed for U-nat, 226Ra and 210Pb? (NRC Reg Guide 4.14) Yes No El N/A Comments: Soil sampling occurred during the first half of the year. 8. Were vegetation samples analyzed for 226Ra and 210Pb? (NRC Reg Guide 4.14) and U-Nat and Th- 232 (LC??) Yes No El Comments: Vegetation sampling occurred during the first half of the year. Page 4 of 8 9. Were radon samples (minus background) taken at Sample Stations BHV-1, BHV-2, BHV-4, BHV- 5, BHV-6, BHV-7 and BHV-8? (NRC Reg Guide 4.14) Yes EA Noill Comments: ECLs in 10 CFR 20 Appendix B Table 2 assume either no daughters present or 100% ingrowth. Calculated ECLs account for partial ingrowth using methodology in EPA 520/1-88-009 p. 2-20. Calculated ECLs result in maximum exposure of 25 mrem/yr vs. 50 mrem/yr using Table 2 value. Regulatory limit is 100 mrem/yr. See the attached Particulate, Radon and Gamma Screening analysis for a summary of quarterly and annual data and a calculated dose at each of the high-volume air stations. 10.
