n the site vicinity. If the natural vegetation or crops near the site are vulnerable to damage from airborne salt particles, a cooling system designed with special consideration for reducing drift may be needed. The vulnerability of existing industries or other nearby facilities to corrosion by cooling tower or spray system drift should be considered. Important factors in assessing drift effects include not only the amount, direction, and distance of the drift from the cooling system, but also the salt concentration above the natural background salt deposition at the site. Salt drift may necessitate special cooling system design features or a larger site to confine drift effects within the site boundary. The environmental effects of salt drift are most severe when condenser cooling water is saline or has high mineral content. 2.2 Hydrology The hydrologic characteristics of potential sites should be evaluated from the perspectives of water quality, water availability, and radionuclide transport. 2.2.2 Water Quality The impact of station construction and operation on water quality in the vicinity of potential sites should be evaluated. 2.2.2.2 Relevant Statutes and Regulations • Clean Water Act; • 40 CFR Part 122, “EPA Administered Permit Programs: The National Pollutant Discharge Elimination System” (Ref. 64); • 40 CFR Part 423, “Steam Electric Power Generating Point Source Category” (Ref. 65); • applicable State water quality standards approved by the EPA; • 10 CFR 20.1101, “Radiation protection programs” o 10 CFR 20.1101(b); • 10 CFR 20.1301, “Dose limits for individual members of the public” o 10 CFR 20.1301(e); • 10 CFR 20.1302, “Compliance with dose limits for individual members of the public;” • 10 CFR Part 50, Appendix I, “Numerical Guides for Design Objectives and Limiting Conditions for Operation to Meet the Criterion "As Low as is Reasonably Achievable" for Radioactive Material in Light-Water-Cooled Nuclear Power
