The Cape Cod Bay Disposal Site (CCBDS) is a regional dredged material disposal site within the state waters of Massachusetts, located in Cape Cod Bay, approximately 15 kilometers (8 nautical miles) southwest of Long Point, Provincetown, Massachusetts. CCBDS is defined as a 1.85 x 1.85 kilometer (1 x 1 nautical mile) area on the seafloor, centered at 41º 54.406’ N, 70º 13.268’ W (NAD 83) which has a relatively flat topography and no natural bathymetric features. The seafloor slopes gently downward to the northwest across the site, with water depths ranging from 28 meters (92 feet) in the southeast corner to 31.5 meters (103 feet) in the northwest corner. 

Monitoring and management of CCBDS is the joint responsibility of the Commonwealth of Massachusetts Department of Conservation and Recreation (DCR) and the DAMOS Program.
