em (i.e., is environmentally preferable). When this is true, the economic costs of mitigation or of the alternative could result in an equivalent or improved projected benefit-cost balance. When these criteria are met, the reviewer should verify those mitigation measures proposed by the reviewers for ESRP Chapters 4.0 and 5.0 or should identify the need for an alternative circulating water system. The reviewer should be guided by the following general considerations: ` The reviewer should keep in mind that an environmental review of alternative circulating water systems, if conducted in the depth applied to the review of the proposed system, would be expected to find additional impacts and/or increased severity of the impacts already predicted for the alternative. The reviewer should allow for this when evaluating the comparative environmental impacts of each proposed alternative with those of the proposed system. ` The reviewer should ensure that the level of detail provided for each economic, environmental, and social cost estimate is commensurate with the level of importance of the related environmental impact. ` The reviewer should adjust the economic costs of each alternative system on the basis of equivalent generating capacity. ` The evaluation of alternative circulating water systems should include consultation and coordination with those agencies responsible for NPDES administration. With the EPM as liaison, the reviewer should coordinate the evaluation of measures and controls to limit or avoid adverse impacts. When consulting through the EPM with the EPA, or with agencies of States that have memoranda of understanding with the NRC, the reviewer should ensure that the staff analyses and evaluations (1) are consistent with the details of these memoranda, (2) will serve the environmental impact statement needs of these agencies, and (3) are consistent with the requirements of the CWA.
