Isles of Shoals North Disposal Site

The Environmental Protection Agency (EPA) is proposing an Ocean Dredged Material Disposal Site (ODMDS) at Isles of Shoals North to serve the southern Maine, New Hampshire, and northern Massachusetts coastal region. The proposed Isles of Shoals North Disposal Site (IOSN) is located approximately 10.8 nautical miles east of Portsmouth, New Hampshire. The availability of an ODMDS in this area is necessary to help maintain the safe navigation of authorized federal channels and permitted actions and projected dredging needs for the area were calculated to be approximately 1.5 million cubic yards of material over the next twenty years. For more information, please visit the Managing Ocean Dumping in EPA Region 1 page.
