documentation. If the applicant can not provide these documents, it shall assess the impact of the proposed action on fish and shellfish resources resulting from heat shock…. Section 4.6.1.2 of the GEIS discusses this issue. If the plant does not use a once-through cooling or closed-cycle cooling pond heat dissipation system, the ER should note this fact, and no additional information need be provided. DG-4015, Page 37 If the plant uses a once-through or closed-cycle cooling pond heat dissipation system and the applicant holds a current NPDES permit that demonstrates that the plant meets State water temperature standards, or a current Clean Water Act Section 316(a) determination, the applicant should provide copies of the determination, NPDES permit, supporting documentation, and relevant correspondence with the water quality permitting agency (EPA or permitting State agency) to the NRC. Additionally, the applicant should describe any potential mitigation measures and state whether they will be implemented. If (1) the plant uses a once-through or cooling pond heat dissipation system and (2) the applicant does not possess a current NPDES permit that demonstrates that the plant meets State water temperature standards or does not possess a current Clean Water Act Section 316(a) determination, the ER must consider issues of thermal impacts. Information that should be provided for review and analysis of the thermal impacts issue is outlined below. Information and Analysis Content The ER should follow the general approach for information and analysis content for all ecology issues as described at the beginning of this section. Specific guidance for this issue follows: • Document any communications with regulatory agencies (e.g., EPA or other water quality permitting agencies) and resource agencies (e.g., NMFS, U.S. Fish and Wildlife Service, State fish and wildlife agencies) regarding the issue of thermal impacts. Provide copies of any NPDES permits and Clean Water
