Ocean Dumping; Proposed Designation of Site

概要

EPA proposes to designate a deep ocean disposal site (proposed SF-DODS) located off San Francisco, California, for the disposal of suitable dredged material removed from the San Francisco Bay and other nearby harbors or dredging sites. EPA has tentatively determined that the site designated in the Final EIS as the preferred site will be the site designated as SF-DODS in this proposed rule. The center of the proposed SF-DODS is located approximately 49 nautical miles (91 kilometers) west of the Golden Gate and occupies an area of approximately 6.5 square nautical miles (22 square kilometers). Water depths within the area range between 8,200 to 9,840 feet (2,500 to 3,000 meters). The center coordinates of the oval-shaped site are: 37 deg. 39.0' North latitude by 123 deg. 29.0' West longitude (North American Datum from 1983), with length (north-south axis) and width (west-east axis) dimensions of approximately 4 nautical miles (7.5 kilometers) and 2.5 nautical miles (4.5 kilometers), respectively. This action is necessary to provide an acceptable ocean dumping site for disposal of suitable dredged material, as determined by appropriate sediment testing protocols. The proposed designat
