Abstract: Abstract: The US Army Corps of Engineers, Mobile District, completed a Survey Report and Environmental Impact Statement in October 1980 for channel improvements to Mobile Harbor, Alabama. This Supplemental Environmental Impact Statement considers the impacts which could result from offshore disposal of dredged material from construction and maintenance of the improved channel. Based upon characteristics of the offshore areas, two sites southwest of the mouth of Mobile Bay were chosen for detailed impact analysis. Impacts include minor release of nutrient constituents and some heavy metals during the disposal operation but not of sufficient concentrations to cause significant adverse biological impacts. Smothering of benthic organisms and turbidity is expected to occur in the immediate vicinity of the discharge point during construction and maintenance of the project, and additionally from natural resuspension of the sediments. Rapid recolonization of similar benthic species is expected to occur after stabilization of the bottom.
