Content:
ter activities, such as proposed intake structures, discharge outfalls, barge slips, dredging activities, pipelines, transmission towers Map spatial extent of in-water building impacts in proximity to important habitat. Include impacts such as pressure effects, noise, turbidity, runoff, drawdowns and dewatering associated with temporary cofferdam installations, etc. Show temporal progression of impacts through map series, if appropriate. Areas subject to habitat modification, conversion, or fragmentation as a result of building activities Spatially explicit depiction of areal extent of proposed habitat disturbance, modification, conversion, fragmentation, or removal. Include type of substrate removed (cobble, sand, silt, clay, etc.) and delineation of depth of disturbance, including quantified estimate of removal or disturbance of infauna and epifauna at levels of individual, population, and species, as appropriate. Also include map depicting proposed structures in place. Identify all important aquatic habitats on such maps. Areas subject to crossing by a transmission line, railroad spur, bridge, causeway, or pipeline right-of-way or access road to such right-of-way Spatially identify locations of aquatic habitats subject to overhead, tunnel, or other crossings of transmission lines, railroad spurs, bridges, causeways, pipelines, access roads, or other features related to the proposed power plant. Include siting of transmission towers if they are adjacent to or within aquatic or wetland habitats. Areas subject to indirect building impacts such as runoff, noise, or atmospheric deposition Map potential impacts to aquatic habitats located downstream or downgradient from short- and long-term building activities. For example, building in uplands could increase sediment and nutrient loads to aquatic habitats through runoff and other such nonpoint sources. Areas subject to direct and indirect operational impacts, such as entrapment; impingement; entrainment; thermal,
