Abstract : This Draft Environmental Impact Statement (DEIS) evaluates the environmental consequences of shock testing the SEAWOLF submarine at an offshore location. The submarine would be subjected to a series of five 4,536 kg (10,000 lb) explosive charge detonations of incrementally increasing intensity sometime between 1 April and 30 September 1997. The DEIS evaluates a 'no action' alternative and analyzes in detail two alternative areas offshore of Mayport, Florida and Norfolk, Virginia. Alternatives are compared with respect to project purpose and need, operational criteria, and environmental impacts. Most environmental impacts of shock testing would be similar at Mayport or Norfolk. These include minor and/or temporary impacts to the physical and biological environments and existing human uses of the area. However, the number of marine mammals potentially affected by the detonations would be about eight times lower at Mayport than at Norfolk. Thus, the preferred alternative is to shock test the SEAWOLF offshore of Mayport, Florida, with mitigation to minimize risk to marine mammals and turtles. If the Mayport area is selected, the shock tests would be conducted between 1 May and 30 September 1997 to minimize risk to sea turtles, which are more abundant at the Mayport area during April. The USS SEAWOLF is the first of a new class of submarines being acquired by the Navy. The class is expected to consist of three submarines, with the second currently under construction. SEAWOLF class submarines will be the largest and most capable fast attack submarines in the fleet. Features include reduced acoustic and electromagnetic signatures, improved speed, greater triaximum operating depth, greater ordnance capacity, and other technological improvements reflecting the state-of-the-art in submarine design.
