WASHINGTON — 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.
The EPA said it will study vinyl chloride to determine whether it poses an “unreasonable risk to human health or the environment,″ a process that would take at least three years.
Vinyl chloride is one of five chemicals the agency is reviewing, including four that are used to make plastics. Other chemicals set for review under the federal Toxic Substances Control Act include acetaldehyde, acrylonitrile, benzenamine, and a compound known as MBOCA.
“Under the Biden-Harris administration, EPA has made significant progress … to strengthen our nation’s chemical safety laws after years of mismanagement and delay. Today marks an important step forward,” said Michal Freedhoff, assistant EPA administrator for chemical safety and pollution prevention.
Studying the safety of vinyl chloride and other chemicals that have been in use for decades “is key to better-protecting people from toxic exposure,” Freedhoff said in a statement.
Environmental and public health activists welcomed the announcement, calling the review long overdue.
“Vinyl chloride was classified as a human carcinogen in 1974. That same year, the federal government wisely banned the use of vinyl chloride in hair sprays, refrigerants, cosmetics and drugs,” said Judith Enck, a former EPA regional administrator and president of the advocacy group Beyond Plastics.
Enck and other advocates had called the toxic train derailment in East Palestine, Ohio, a…
