ling water intake are regulated through the National Pollutant Discharge Elimination System (NPDES) permit system. The Clean Water Act requires that the location, design, construction, and capacity of the cooling water intake structure reflect the best technology available for minimizing environmental impacts. Responsibility for making this determination rests with the EPA or with its designees. In the most practical terms, the reviewer’s final evaluation is determined through professional judgment based on the pertinent data and analyses. The reviewer may refer to earlier NRC environmental reviews in which evaluation of intake system operational impacts has been important. The reviewer should take the following steps: (1) Determine whether the applicant has provided a current NPDES permit with a 316(b) determination, if appropriate, or equivalent State permits and supporting documentation. If these documents are not available, not current, or do not reflect conditions during the license renewal term, continue the analysis at Step (2). Otherwise, prepare a statement for the SEIS describing the potential for entrain- ment of fish and shellfish in early life stages that ` summarizes the permitting documents that have been reviewed ` states that a current NPDES permit and 316(b) determination are available and current NUREG-1555 5.3.1.2-6 October 1999 ` concludes that there are no cooling water intake system impacts of entrainment on fish and shellfish in early life stages. (2) Identify the “important” aquatic organisms and their life stages susceptible to entrapment, impinge- ment, or entrainment, coordinating efforts with the reviewer of ESRP 2.4.2 to ensure that these susceptible “important” species are also described in that ESRP. If fish and shellfish species are present and are susceptible to entrainment such that effects will be detectable or may destabilize or noticeably alter fish or shellfish population levels, then continue the analysis at Step
