The Biden administration has initiated a formal evaluation of risks posed by vinyl chloride, the cancer-causing chemical that burned in a towering plume of toxic black smoke following a fiery train derailment earlier this year in eastern Ohio.
The Environmental Protection Agency said it will review risks posed by a handful of chemicals, including vinyl chloride, which is used to make a variety of plastic products, including pipes, wire and packaging materials. The chemical is found in polyvinyl chloride plastic, better known as PVC.
