by site- and station-specific factors, and the degree of detail should be modified according to the anticipated magnitude of the potential impacts. The following types of data or information should be obtained: ` obtain a copy of the plant’s current NPDES permit. If this is not available, obtain the following: - thermal - data on temperature duration mortality relationship of susceptible “important” aquatic species (from the environmental report [ER] and the general literature) - additional information about thermal characteristics as they relate to the discharge system taken from other ESRPs, including ESRPs 2.4.2 and 5.3.2.1, which describe the aquatic ecology of the site and its environs and the physical impacts of the discharge system. ` chemical - tolerances of the “important” aquatic species identified in ESRP 2.4.2 to acute and chronic exposure to chemicals in the plant discharge (from the ER and the general literature) - tolerances of “important” aquatic species identified in ESRP 2.4.2 to acute and chronic exposure to dissolved gases (from the ER and the general literature) - additional information on the biological effects of chemical alterations to the receiving water body obtained from other ESRPs, including ESRPs 2.3.3 and 3.6.1, which describe the water quality of the site and chemical and biocidal nonradiological wastes. ` physical, including information regarding biological effects of physical alterations to the receiving water body obtained from other ESRPs, including ESRPs 2.3.1 and 5.3.2.1, which discuss the hydrology of the site and the physical impacts of the discharge system ` a description of the condenser cooling system because its configuration can determine which permits must be acquired and the severity of impacts on particular aquatic organisms or systems ` a description of applicable State and Federal (40 CFR 423) effluent guidelines and the thermal standards or limitations applicable to the water body to which the
