The U.S. Environmental Protection Agency (EPA) proposed on April 12, 2022, to prohibit ongoing uses of chrysotile asbestos, the only known form of asbestos currently imported into the United States. 87 Fed. Reg. 21706. EPA proposes under Section 6(a) of the Toxic Substances Control Act (TSCA) to prohibit manufacture (including import), processing, distribution in commerce, and commercial use of chrysotile asbestos in bulk or as part of chrysotile asbestos diaphragms used in the chlor-alkali industry and chrysotile asbestos-containing sheet gaskets used in chemical production. EPA proposes that these prohibitions take effect two years after the effective date of the final rule. EPA also proposes to prohibit manufacture (including import), processing, distribution in commerce, and commercial use of chrysotile asbestos-containing brake blocks used in the oil industry, aftermarket automotive chrysotile asbestos-containing brakes/linings, other chrysotile asbestos-containing vehicle friction products (not including the National Aeronautics and Space Administration (NASA) Super Guppy Turbine aircraft use), and other chrysotile asbestos-containing gaskets.
