The Environmental Protection Agency has finalized a suite of regulations related to polychlorinated biphenyls, including extraction, disposal, and cleanup regulations. The changes are expected to facilitate less costly cleanups for the chemicals as well as reduce waste in the extraction process.

PCBs were manufactured and used in the United States from the early 20th century until PCB manufacture was banned in the country in 1979 (with limited exceptions). PCBs were utilized in a wide array of industrial applications due to their non-flammability, chemical stability, high boiling point, and electrical insulating properties.
