ect to providing a description of the applicant’s planned cooling system components. Technical Rationale The technical rationale for evaluating the applicant’s description of the components of the proposed cooling system is discussed in the following paragraph: Detailed drawings and descriptions of the characteristics of the cooling system should be available for analysis to review the applicant’s cooling system component design and performance character- istics so that the environmental assessment of construction and operation may be evaluated. III. REVIEW PROCEDURES The reviewer’s analysis of the intake, discharge, and heat dissipation system component descriptions should be closely linked with the assessment of construction and operational impacts directed by ESRP Chapters 4.0 and 5.0. The intent of this analysis is to identify and describe the design and performance characteristics of the proposed cooling components that can be expected to cause environmental impacts as a result of construction or operation. The characteristics generally considered are listed under “Data and Information Needs” in this ESRP. Each cooling system component should be analyzed, and the reviewer should prepare descriptions of the design and performance characteristics that are generally expected to result in environmental impacts (e.g., intake configuration, flow velocity through traveling screens, cooling tower drift). The review should be based on the cooling system components described in the applicant’s ER and should consider component performance for the operational modes described by the reviewer for ESRP 3.4.1. With this in mind, the reviewer should take the following steps: (1) For all systems, evaluate intake and discharge temperatures and the temperature rise across the condenser. (2) For cooling towers, determine average discharge temperatures for each month of the year using cooling tower performance curves. The average discharge temperature will be
