Final Environmental Statement. Sebewaing River, Michigan. Operation and Maintenance, Confined Disposal Facility, and Flood Control Facilities.
Abstract
The proposed Federal action includes maintenance dredging of the Sebewaing River navigation and flood control channel, construction of a confined disposal facility for contaminated dredge material, repair of stop-logs and other structures forming the flood protection project, maintenance of navigation structures protecting the channel, and, as necessary, dynamiting the ice jams to prevent flooding of the Village of Sebewaing. Dredging and disposal activities will have temporary adverse effects on water quality, organisms living in and on the bottom sediments in affected areas, aesthetics, recreational fishing, and the ability of the area to support aquatic life. Beneficial impacts of maintenance dredging include continuance of the existing flood carrying capacity of the river and continuance of the existing local economy through preservation of navigation dependent commercial enterprises. Maintenance of existing flood control facilities may have temporary adverse effects on water clarity, vegetation on levees, and small animals residing in and on the facilities. Beneficial effects include keeping the structures in aesthetically pleasing, functioning condition, thereby reducing the threat of flooding in the Village of Sebewaing.
