Ex-ORISKANY Artificial Reef Project: Ecological Risk Assessment; Final rept

摘要

The purpose of this report is to assess the potential ecological risks from polychlorinated biphenyl (PCB) exposure associated with sinking the aircraft carrier ex-ORISKANY (CVA-34, Figure 1) to create an artificial reef off the coast of Pensacola, FL (Figure 2) within the Escambia East Large Area Artificial Reef Site (Figure 3). Sinking the vessel requires a risk-based disposal approval under 40 CFR 761.62(c) because the ship contains PCBs in solid materials such as electrical cabling, gaskets, rubber products, insulation, and paints that contain concentrations of polychlorinated biphenyls (PCBs) greater than or equal 50 ppm.
