ms, to the extent needed to prepare a description of the purpose and nature of each system: Note: The principal types of treatment systems that should be described include those necessary to condition (1) the intake water for noncooling-system use within the plant and (2) water used in the plant cooling system and treatment systems required for providing potable water. Chemicals used in these systems should be described. NUREG-1555 3.3.2-4 October 1999 (1) Include a brief description of treatment system operating procedures, including plant operational and seasonal variations (AWWA 1990). (2) Further define each treatment system in terms of the purpose of the proposed processes and the chemicals required. (3) Identify the proposed use of chemicals. Only the systems that result in a waste discharge need to be analyzed in detail, and the reviewer should emphasize the systems that have a potential for requiring an NPDES permit. (4) Verify that ` All water streams identified in ESRP 3.3.1 have been considered. ` All chemicals (identification and quantities) to be used have been considered or described. ` The status of NPDES permits and consultations with NPDES administrative agencies have been discussed. ` The proposed systems have been described in sufficient detail to permit assessment of environmental impacts resulting from their operation. (5) Ensure that the water treatment information is adequate to serve as a basis for assessing the impacts of station construction and operation on water use. IV. EVALUATION FINDINGS As input to the EIS, the reviewer should provide a concise description of the proposed water treatment systems that results in waste discharge and include a tabulation of chemicals to be added by quantity and frequency of addition. Proposed systems that do not result in waste discharges should be identified, but not described in detail. Unresolved differences between the staff’s analysis and the applicant’s proposed operation of any water-treatment
