consider the following factors: - bathymetric characteristics in the vicinity of the site - type of cooling system employed and its probable operating modes - transient hydrological parameters in the vicinity of the site - vertical and horizontal temperature and salinity structure in the vicinity of the site. ` the sampling frequency and times to ensure that important temporal variations (e.g., tidal variations) are adequately monitored ` the duration of monitoring programs ` the data analysis procedures. ` data quality objectives (if any) October 1999 6.1-5 NUREG-1555 Preoperational Monitoring The preoperational monitoring program supplements any preapplication monitoring in providing a baseline water temperature database. Discussion of the applicant’s preoperational monitoring plan should mention the following: ` the average and extreme extent and enclosed surface area of the limiting excess temperature isotherms as established by the NPDES permitting agency, by comparison with background and baseline data ` temperatures at positions appropriate to define the extent of the mixing zones (proposed or established) ` time temperature relationships at biological monitoring stations ` any other parameters required by the NPDES permitting agency ` data quality objectives (if any). Operational Monitoring The operational monitoring program is designed to establish changes in water temperature resulting from plant operation. NPDES permitting agencies will specify operational monitoring requirements. The reviewer should describe the status of NPDES permit consultations and NPDES permit renewal. IV. EVALUATION FINDINGS Input from the ESRP 6.1 review to the environmental impact statement (EIS) should describe results of the preapplication monitoring program review and should present the objectives of the preoperational monitoring program without detail. The reviewer should briefly outline monitoring station locations and methods, frequency, and duration of sampling used.
