Riepilogo

With the publication of this Final Rule, the Environmental Protection Agency (EPA) is designating one ocean dredged material disposal site (ODMDS), the Isles of Shoals North Disposal Site (IOSN), located in the Gulf of Maine off the coast of southern Maine and New Hampshire, pursuant to the Marine Protection, Research, and Sanctuaries Act (MPRSA). This action is necessary to serve the long-term need for an ODMDS for the possible future disposal of suitable dredged material from harbors and navigation channels in southern Maine, New Hampshire, and northern Massachusetts. The basis for this action is described herein and in the Final Environmental Assessment (FEA). The FEA identifies designation of the IOSN as the preferred alternative from the range of options considered. The Site Management and Monitoring Plan (SMMP) is provided as Appendix G of the FEA.
