About PCBs

• PCBs were developed and used by many industries for their fire retardant and insulating properties. PCB hydraulic fluids were used at the GM Powertrain Bedford Plant from 1965 to the early 1970’s as a safety measure to prevent fires. PCBs were later restricted by the federal government in 1978 through the Toxic Substances Control Act (TSCA).
