ument the results of radiological surveys conducted during plant operation in characterizing radiological contamination, and plan decommissioning at the time of license termination. 10. In determining compliance with the EPA generally applicable environmental radiation standards of 40 CFR Part 190, as implemented under 10 CFR 20.1301(e), the review confirms that the ODCM includes the appropriate methodology to account for all sources of radiation and radioactivity contained in liquid and gaseous effluent discharges as potential contributors to doses to members of the public from the site, which may have multiple reactor units. The review focuses on methods used to assess the total dose from sources of radioactivity, external radiation exposures from waste processing buildings, waste storage buildings, waste storage tanks, temporary waste storage or staging areas, spent-fuel storage, and N-16 skyshine from BWR turbine buildings. The source terms and associated doses from liquid and gaseous effluent 11.5-39 Revision 6 – January 2016 discharges associated with the operation of the LWMS, GWMS, and SWMS are evaluated using the guidance in SRP Sections 11.2 to 11.4. Doses associated with external radiation from buildings and sources of radioactivity contained in systems and components are evaluated using the guidance in SRP Sections 11.1 and 12.3-12.4. The reviewer should determine whether the applicant has applied site-specific information in assigning doses for all identified exposure pathways, or instead has assumed that all exposures occur at one location or in one sector in bounding dose estimates, where doses from liquid and gaseous effluent releases and external radiation are summed up and compared to the EPA standards. For OL and COL applicants with site-specific information on the locations of offsite dose receptors, compliance with the EPA standards should provide the justification on the apportionment of doses due to liquid and gaseous effluent releases and
