nt to characterize seasonal variations throughout at least one annual cycle. Additional data (e.g., spawning periods for “important” species) may be needed on a site-specific basis. ` Evaluate the preapplication monitoring program to determine that it is adequate to support the environmental descriptions in ESRP 2.4.2. These data should cover the following: NUREG-1555 6.5.2-6 October 1999 - the distribution and abundance of “important” species and habitats. Critical life history information should include parameters such as spawning areas, nursery grounds, food habits, feeding areas wintering areas, and migration routes to the extent that the proposed project is expected to affect these parameters. - descriptions of any modifications that may contribute to the existing patterns of plant and animal communities such as dams, dredging, clearing of stream banks, etc. Site Preparation and Construction Monitoring This monitoring is appropriate for applications for a construction permit or a combined license, and is the proposed program of aquatic environmental monitoring to control anticipated impacts from site prepara- tion and plant construction. Construction monitoring will be required only when specific adverse impacts are predicted and when conscientious construction practices coupled with systematic inspection is insufficient. When evaluating site preparation and construction monitoring, ` determine the predicted impacts from the output of the environmental reviews of ESRPs 4.2 and 4.3.2 ` analyze the proposed monitoring programs associated with these predicted impacts to determine if adequate impact assessment is possible and that adequate mitigation programs can be selected if needed. Preoperational Monitoring A program of aquatic environmental monitoring may 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
