te visit, inspect areas where construction activities will occur, and inspect all other potentially impacted areas. ` When necessary, supplement the data and information specified in this part through consultations with Federal, State, regional, local, and affected Native American tribal agencies (e.g., the U.S. Fish and Wildlife Service and State fish and wildlife agencies). (2) Review impacts of construction on aquatic ecology: Review and discuss the following impacts: October 1999 4.3.2-7 NUREG-1555 (a) Determine how construction activities will impact “important” species and their habitats (e.g., those resulting from scouring and siltation, dredging and soil disposal, and interference with shoreline processes), and estimate the magnitude and duration of such impacts. (b) Determine the impacts of construction on threatened or endangered species, evaluating these impacts relative to the local population and the total estimated population over the entire range of the species as noted in the literature. (c) Identify water bodies receiving construction effluents and the expected average and maximum flow rates, composition, and physical characteristics of these effluents (from ESRP 4.2). (d) Describe proposed construction management practices for the amelioration of impacts (from the ER). For example, ` avoid narrow reaches of water bodies and important habitats as sites for locating intake or discharge structures ` provide a zone of passage that permits normal movement of “important” species populations and maintenance of the harvestable crop of economically important populations. (e) For important species having commercial or recreational value, estimate the magnitude of the impact. This may be expressed in terms of dollars, lost opportunity for recreational pursuits, percent reduction in harvest, percent loss of habitat, or other appropriate quantifiers. In absence of more sophisticated population models, these determinations can usually be based on percent
