 The Toxic Substances Control Act (TSCA), passed in 1976 worked to regulate the sale and use of chemicals in the U.S, but its primary focus was on polychlorinated biphenyls (PCBs).Its effects on the Kettleman Hills Hazardous Waste Facility is similar to the RCRA by requiring permitting by the EPA in order to make the requested 14 acre expansion into a site which allows for the dumping of PCBs.During this permitting process, the TSCA PCB permit application requires the EPA to issue a public notice once a decision has been reached, as well as hold a 60-day formal comment period for the public, as well as a formal public hearing.
