Cape Arundel Disposal Site

Portland Disposal siteThe Cape Arundel Disposal Site (CADS) is defined as a 457 meter (1500 feet) diameter circle on the seafloor with its center located approximately 5.1 kilometers (2.7 nautical miles) south-southeast of Cape Arundel, Maine. Water depths at CADS vary from 30 meters (98 feet) to 42 meters (138 feet) with a complex bottom topography. As an alternative dredged material disposal site selected by the Corps of Engineers (and not a formally designated site by the USEPA), CADS was closed in 2010 when its temporary status ended. Congressional legislation reopened the site in 2014 and the site remains open until 31 December 2021 with a volume limitation of 80,000 cubic yards from any single dredging project.
