aph: The consideration of alternatives is the essence of the NEPA process. The review conducted under this ESRP section contributes to the consideration of alternatives by addressing alternative means of power transmission to determine if there is an obviously superior system design or transmission corridor in terms of environmental impacts and economic costs when compared to the proposed system. III. REVIEW PROCEDURES The principal objectives of this analysis procedure are (1) to provide assistance to those ESRP Chapter 4.0 and 5.0 reviewers concerned with identifying and verifying means to mitigate adverse impacts associated with the proposed transmission system and (2) to identify and analyze reasonable alternatives to the applicant’s proposed system to the extent needed to rank them, from an environmental standpoint, as preferable, equivalent, or inferior to the applicant’s proposed system. The depth of the analysis should be governed by the nature and magnitude of proposed transmission- system impacts predicted by the ESRP Chapter 4.0 and 5.0 reviewers. When adverse impacts are predicted, the reviewer should coordinate with these reviewers in identifying and analyzing means to mitigate these impacts. The proposed system with any verified mitigation schemes (i.e., measures and controls to limit adverse impacts) should be the baseline system against which alternative transmission systems will be compared. The nature and adversity of the remaining unmitigated impacts for this baseline system should establish the level of analysis required in the review of alternative systems to permit staff evaluation and conclusions with respect to the environmental preference or equivalence of these alternatives. When no adverse impacts have been predicted for the proposed system, the review should be limited to an analysis of alternative transmission systems in the depth necessary to judge their environmental equivalence to the applicant’s proposed system.
