ations (NRC 1998), contains guidance on factors that should be considered in the site-selection process. In specific regard to cooling-tower drift, this guide states “The potential loss of important terrestrial species and other resources should be considered.” ` Regulatory Guide 4.11, Rev. 1, Terrestrial Environmental Studies for Nuclear Power Stations (NRC 1977), contains technical information for the design and execution of terrestrial environmental studies, the results of which may be appropriate for inclusion in the applicant’s ER. The reviewer should ensure that the appropriate results concerning potential effects of the heat-dissipation system on the terrestrial environment are included in the ER. NUREG-1555 5.3.3.2-4 October 1999 Technical Rationale The technical rationale for evaluating the applicant’s impacts from heat-dissipation systems to terrestrial ecosystems is discussed in the following paragraph: The EIS needs to include the results of an analysis that considers the environmental effects of the proposed heat dissipation system and the alternatives available for reducing or avoiding adverse environmental effects. Any environmental benefits that may result from the operation of the heat dissipation system should also be included. Following the acceptance criteria listed above will help ensure that the environmental impacts of the proposed heat-dissipation system are considered with respect to matters covered by such standards and requirements. III. REVIEW PROCEDURES The depth and extent of the input to the EIS will be governed by the environmental characteristics of the terrestrial ecology that could be affected by operation of the stationGs heat dissipation systems and by the magnitude of the expected impacts to the terrestrial environment. The most apparent effects of heat dissipation systems on terrestrial ecosystems are those associated with cooling-tower or spray pond operation. These include the effects of vapor plumes, icing, and salt
