Two Connecticut companies, a scrap metal recycling facility and a waste oil transporter, agreed to pay fines to settle claims by the U.S. Environmental Protection Agency that they violated federal laws regarding toxic substances in their handling of polychlorinated biphenyls (PCBs). In addition, as part of the settlements one company will clean up PCB contamination and the other has voluntarily changed operations to reduce the chance of contaminating waste oil shipments with PCBs.
