e measures and controls to limit adverse impacts proposed by the applicant and concurred with by the staff. For those alternatives eliminated from consideration on the basis of land use, water use, or legislative restrictions, the reviewer should ensure that adequate documented justification for this action has been prepared. (1) General Considerations (a) If a mitigation measure or alternative transmission system is being considered, the reviewer should determine first that the measure or system being evaluated has a lesser overall environ- mental impact than the proposed system (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 project benefit-cost balance. When these criteria are met, the reviewer should verify that those mitigation measures proposed by the reviewers for ESRP Chapters 4.0 and 5.0 will meet the criteria as a feasible alternative transmission system. (b) The reviewer should keep in mind that an environmental review of alternative transmission sys- tems, 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 alter- native. The reviewer should allow for this when evaluating the comparative environmental impacts of each proposed alternative with those of the proposed system. October 1999 9.4.3-11 NUREG-1555 (c) 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 environ- mental impact. (2) Measures and Controls to Limit Adverse Impacts (a) When considering measures identified by the reviewers for ESRP Chapters 4.0 and 5.0 to miti- gate adverse environmental impacts predicted for the proposed transmission system, the reviewer’s verification of the desirability of the measure should reach the
