few percent of important habitat types. The reproductive capacity of important populations and the harvestable crop of economically or recreationally important populations should be maintained unless proposed or probable changes can be justified. If sites contain, are adjacent to, or could affect important ecological systems or habitats (e.g., wetlands and estuaries) that are unique, limited in extent, or necessary to the productivity of populations of important species, they cannot be evaluated as to suitability for a commercial nuclear power station until adequate assessments have been completed to reliably predict impacts and facility DG-4034, Page 39 design characteristics have been defined that would satisfactorily mitigate these impacts. In areas where reliable and sufficient data are not available, it may be necessary to collect and evaluate appropriate seasonal data. When early site inspections and evaluations indicate a need to study critical or exceptionally complex ecological systems in detail to determine the appropriate plant designs, proposals to use such sites should be deferred unless sites with less complex characteristics are not available. 2.3.3 Migratory Routes of Important Species Migration routes of important species that pass through the site or its environs should be identified. Construction and operation of commercial nuclear power stations can create barriers to migration. 2.3.3.2 Relevant Statutes and Regulations • Fish and Wildlife Coordination Act, as amended; • Migratory Bird Treaty Act of 1972, as amended; and • Magnuson-Stevens Fishery Conservation and Management Act, as amended. 2.3.3.3 Related Guidance • NUREG-1555, “Standard Review Plans for Environmental Reviews for Nuclear Power Plants: Environmental Standard Review Plan;” • RG 4.2, “Preparation of Environmental Reports for Nuclear Power Stations;” and • RG 4.11, “Terrestrial Environmental Studies for Nuclear Power Stations.” 2.3.3.4 Considerations,
