Polychlorinated biphenyls (PCBs) are highly toxic agents which have been shown to cause harmful affects in numerous animal species, including man. PCBs have been used and manufactured in Europe, Japan, the Soviet Union, and the United States. The characteristics that cause PCBs to have broad industrial uses also make their safe disposal very difficult. The environmentally preferred option for disposing of PCB containing wastes is incineration. At the present time, three non-mobile incinerators have been approved by the USEPA for burning PCBs in the United States. Based in large part on the results of stack tests from five trial burns conducted in October of 1982, the USEPA and Illinois EPA approved permits to incinerate liquid and non-liquid PCB wastes at the Chicago facility. The Illinois IEPA will be conducting a four month field monitoring program to sample and analyze PCBs in the atmosphere around the SCA incinerator to further assess the environmental impact of the incineration of PCBs. This document presents the overall plan for this project.
