ally preferable by the evaluation procedures of this ESRP. Initial Environmental Screening The reviewer should consider the following factors in the initial environmental screening of each alternative circulating water system to eliminate those systems (or components) that are obviously unsuitable for use at the proposed site. Economic factors should not be considered in this initial screening. ` plant water requirements ` site terrain and relationship to water bodies NUREG-1555 9.4.2-8 October 1999 ` water body geometry ` other water use ` ecological considerations ` legislative restrictions. The following steps should be considered by the reviewer as part of the initial environmental screening procedures for each system: ` Work through the EPM to consult with appropriate Federal, State, regional, local, and affected Native American tribal agencies when needed to conduct this screening. ` Consult the appropriate NPDES administrative agencies to screen for those alternatives that will not meet CWA requirements. ` Establish any other justifiable environmental bases for rejection of a given alternative. When the reviewer rejects an alternative, that alternative needs no further consideration other than preparation of the reasons and justification for the rejection. (1) Intake Systems—To analyze alternative intake systems, the reviewer should perform the following steps: (a) Consult with the appropriate ESRP Chapter 4.0 and 5.0 reviewers to identify any mitigation measures or potentially superior alternative intake systems identified by these reviewers. (b) Consider the following classes of alternatives: ` alternative intake systems (e.g., offshore vs. shoreline) ` proposed system design modifications (e.g., reduced intake velocity, fish return system) ` alternative locations of proposed system (e.g., up/downstream, alternative water bodies) ` alternative procedures (e.g., screenwash operation, thermal defouling). (c) Consider the following environmental impacts and
