Content:
fication and description of project related construction activities expected to result in hydrologic alterations at the site, transmission corridors, and offsite areas. Activities include construction of cofferdams and storm sewers; dredging operations; placement of fill material into the water; creation of shoreside facilities involving bulkheads, piers, jetties, basins, or other structures or activities with potential to alter existing shoreline processes; construction of intake and outfall structures; water channel modifications; construction of roads and bridges; operations affecting water levels (flooding); dewatering activities; and construction activities contributing to sediment runoff, e.g., road construction, clearing and grading, fill or spoil placement (from the environmental report [ER], the site visit, and consultation with Federal, State, regional, local, and affected Native American tribal agencies). ` identification of water sources used during construction and the average and maximum use rates of these waters (from the ER) ` identification of water bodies receiving construction effluents and the expected average and maximum flow rates and physical characteristics (temperature, sediment load, velocities) of these effluents (from the ER) ` identification of hydrologic alterations expected to result from the project related construction activities listed previously. Examples include changes in water drainage characteristics, the flood- handling capability of the floodplains flow and circulation patterns, subsidence resulting from groundwater withdrawal, and erosion and sediment transport (from the ER). ` identification and location of groundwater and surface-water users and areas that could be affected by project related hydrologic alterations (from ESRP 2.3.2, the ER, and the site visit) ` descriptions of proposed practices and measures to limit or minimize expected hydrologic alterations (from the ER) ` Federal, State, regional, local, and affected
