etail any structural or operational measures, such as the schedule of traveling screen operation or planned outages, used to reduce impingement of fish and shellfish. This description should include a typical water balance or budget showing rates of water withdrawal, losses to evaporative cooling (for cooling towers), blowdown, effluent, and the like. The ER should also describe typical temperature changes as water passes through the system, as well as temperatures at the outfall, the size of the plume and mixing zone, and National Pollutant Discharge Elimination System (NPDES) or other permit conditions on temperature. The ER should include copies of such permits and supporting documentation in an appendix. This section should also describe chemical additions or other measures used to clean or maintain condensers and other components. The surface water and impingement and entrainment sections of the ER should refer to this section when appropriate to avoid unnecessary duplication of effort. Radioactive Waste Management Each nuclear power plant has a radioactive waste system to collect, treat, and dispose of the radioactive and potentially radioactive wastes that are byproducts of plant operations. Radioactive wastes are classified as liquid, gaseous, or solid. To assist the NRC staff in its review, the ER should provide a brief plant-specific description of the major features of the liquid, gaseous, and solid radioactive waste management system. The information should include, at a minimum, a physical description of the systems and the types of treatment used (i.e., filtration, demineralizers, dewatering, and resin filtration for liquid wastes), a discussion concerning the use of an offsite waste processor, and details about the transportation and disposal of the waste and/or onsite storage facilities. Nonradioactive Waste Management Each nuclear power plant has a nonradioactive waste system to collect, treat, and dispose of the nonradioactive wastes that are
