latory Guide 4.2, Rev. 2, Preparation of Environmental Reports for Nuclear Power Stations (NRC 1976), details the means by which the applicant collects baseline data used to compare subsequent data to evaluate plant construction and operation impacts. The reviewer should ensure that the applicant’s measurement of conditions before site preparation includes all environmental parameters necessary to evaluate impacts during station operation, as well as during site preparation and construction. ` Regulatory Guide 4.7, Rev. 2, General Site Suitability for Nuclear Power Stations (1998), contains guidance concerning the ecological systems and biota at potential sites and requires that their environs be sufficiently well-known to allow reasonably certain predictions that there would be no unacceptable or unnecessary deleterious impacts on populations of important species or on ecological systems with which they are associated from the construction or operation of a nuclear power station at the site. The reviewer should ensure that the applicant’s description of the site and transmission corridors identify important species or ecological systems that could potentially be impacted by station and transmission corridor construction or operation. Technical Rationale The technical rationale for evaluating the applicant’s description of the area’s aquatic ecology is discussed in the following paragraph: A detailed and thorough description of the aquatic ecology in the vicinity of the power station site and associated transmission corridors is essential for the evaluation of potential impacts to the aquatic environment that may result from plant construction or operation. Use of the above acceptance criteria will help ensure inclusion of the aquatic ecological attributes most needed to predict impacts. III. REVIEW PROCEDURES The reviewer should ensure that the regional and site-specific aquatic ecological information is adequate to serve as a basis for assessment of the
