Are polychlorinated biphenyls (PCBs) regulated as hazardous waste?
PCB’s are regulated under the Toxic Substances Control Act (TSCA). This program is not delegated to the State of Oklahoma. Questions regarding PCB’s should be directed to EPA Region 6 in Dallas, Texas, (214) 665-7579. Mixtures of hazardous waste and PCB’s are regulated by both the EPA and DEQ. Both the TSCA and hazardous waste regulations apply to such mixtures.
