eading to maximum individual dose commitments, take the following steps: (1) Based on information provided by the applicant, information obtained during the site visit, consul- tation with appropriate ESRP Chapter 2.0 reviewers, and consultation with appropriate Federal, State, regional, local, and affected Native American tribal agencies, ` Develop a list of “nearest” receptors as described in this ESRP. ` For each such location, categorize the important pathways (i.e., direct radiation or gaseous or liquid effluent) by which radiation can be transferred to the receptor. (2) For gaseous pathways ` Give the location data to the reviewer for ESRP 2.7, Meteorology, for determining atmospheric transport and diffusion characteristics needed to determine dose commitments at these locations. ` Give the reviewer for ESRP 2.7 assistance as needed to complete this interrelated portion of the environmental review. Note: For early site permit applications, consult with the ESRP 2.7 reviewer to determine a conservative effluent release point for the hypothetical plant. (3) For liquid pathways ` Consult with the reviewer of ESRP 3.5 to complete the analysis of the information required in this ESRP and with the reviewer of ESRP 2.3.1, to complete the analysis of transit and dilution times. When these reviewers determine that the applicant supplied values for transit time and dilution are conservative (e.g., with respect to stream flow and velocity), the applicant’s data may be used without further analysis. October 1999 5.4.1-9 NUREG-1555 ` For early site permit applications, consult with the reviewers of ESRPs 2.3.1 and 3.5 to deter- mine the optimum effluent release point given the applicant’s general statements about proposed cooling systems. ` If the applicant’s data are not conservative or if subsequent dose-estimations calculations and analyses made by the reviewers of ESRPs 5.4.2 and 5.4.3 predict that doses will exceed the 10 CFR 50, Appendix I, guidelines,
