This Draft Environmental Impact Statement (DEIS) describes the environmental effects of designating a dredged material disposal site(s) in western and central Long Island Sound. The DEIS describes the evaluation of open ocean, upland, beneficial use, treatment technologies, and four open-water alternatives for dredged material disposal and a No Action Alternative. Initial screening eliminated the open ocean, upland, beneficial use, and treatment technology alternatives. The remaining alternatives were then assessed throughout the document. The primary potential effects identified include: temporary increase in suspended solids and burial of aquatic resources. The Environmental Protection Agency's Preferred Alternative is to designate the Western Long Island Sound and Central Long Island Sound Dredged Material Deposit sites.
