be necessary to establish a baseline for identifying and assessing the environmental impacts to aquatic biota resulting from plant operation. Preoperational monitoring programs should be evaluated for applications for an operating license or a combined license. Any necessary preoperational monitoring will ordinarily be defined in the NPDES permit. When evaluating preoperational monitoring, analyze the available data to determine that they are adequate to support the environmental descriptions in ESRP 2.4.2, being sure to consider the following: ` the location and value of commercial and sport fisheries by species, season, and catch ` the distribution and abundance of “important” fish, shellfish, and other invertebrates including benthos. Critical life history information should include spawning areas, nursery grounds, feeding areas, wintering areas, and migration routes. October 1999 6.5.2-7 NUREG-1555 ` endangered or threatened species that are known or expected to be present, together with any specific habitat requirements or community interrelationships ` the physical, chemical, and biological factors known to influence the distribution and relative abundance of “important” species ` station features and operations that contribute to the existing patterns of plant and animal communities, and that may increase the presence and abundance of nuisance organisms. Operational Monitoring A program of aquatic ecological monitoring may be necessary to establish a baseline for use and evalua- tion of the environmental impacts of continued plant operation. It continues the studies conducted during preoperational monitoring. Operational monitoring programs should be evaluated for applications for an operating license or a combined license. Any necessary operational monitoring program will be covered under the relevant NPDES permit. General When evaluating these four types of monitoring programs, the following features should be considered: (1) Ensure that the
