eliminated from consideration, the reviewer should ensure that adequate documented justification for this action has been prepared. (1) The initial step in the evaluation of alternative energy sources and systems should be to categorize these systems as environmentally preferable, equivalent, or inferior to the proposed project. The following criteria should be applied to this evaluation: ` When the reviewer determines that the proposed project (with mitigation measures, if necessary) will have no unavoidable adverse impacts and will comply with applicable Federal, State, regional, local, and affected Native American tribal regulations, the reviewer should conclude that there can be no environmentally preferable alternatives. When this conclusion is reached, the reviewer should evaluate the alternatives to identify those that may be considered environmentally equivalent. For this condition, environmental equivalence means that an alternative should have no unavoidable adverse impacts and meet applicable regulatory requirements. Alternatives having unavoidable adverse environmental impacts or that do not meet regulatory requirements should be judged environmentally inferior to the proposed project under these conditions. ` When the reviewer determines that the proposed project will meet regulatory requirements, but is predicted to have unavoidable adverse environmental impacts, the reviewer should evaluate the identified alternative systems for potential environmental preference to the proposed system. The scope and extent of this evaluation should depend on the nature and magnitude of the proposed project’s environmental impacts and may lead to an environmental review for the alternatives following the analysis and evaluation procedures of the appropriate ESRP Chapters 4.0 and 5.0. The following criteria apply to this evaluation: - Environmental preference will be established when an alternative can be shown to have no unavoidable adverse impacts and will meet
