Abstract:

This document supplements the FEIS by not only describing continuing dredging requirements of the Navy to insure the successful introduction of the new deep-draft SSN 688 class submarines at the U.S. Naval Submarine Base, but also by correcting deficiencies noted in the decision of the United States Circuit Court of Appeals in National Resources Defense Council et al. v. Callaway et al. Navy dredging requirements in support of the SSN 688 class submarines are projected over a ten year period. Four segments of the required dredging are required immediately and are scheduled to commence in 1976. The immediate dredging requirement 1976-1977 totals an estimated 1.8 million cubic yards and is proposed for disposal at the New London Dumping Ground. An additional 1.0 million cubic yards is projected through 1985. Approximately 2.8 to 2.9 million cubic yards of material would be dredged and deposited at a designated ocean disposal site. The channel and berthing improvements would assure the development of the full capabilities of the new SSN 688 class submarine. The increased channel depths in New London Harbor would benefit the local economy by increasing commercial shipping in the area. The report concludes that continued use of the New London Dumping Ground is the most environmentally acceptable disposal site for project spoils.
