EPA announced a final rule to prohibit ongoing uses of chrysotile asbestos, the only known form of asbestos currently used in or imported to the United States. The ban on ongoing uses of asbestos is the first rule to be finalized under the 2016 amendments to the nation's chemical safety law, the Toxic Substances Control Act (TSCA), which received near-unanimous support in both the U.S. House of Representatives and the Senate. The action marks a major milestone for chemical safety after more than three decades of inadequate protections and serious delays during the previous administration to implement the 2016 amendments. Exposure to asbestos is known to cause lung cancer, mesothelioma, ovarian cancer, and laryngeal cancer, and it is linked to more than 40,000 deaths in the U.S. each year.
