The Environmental Protection Agency (EPA) is proposing a rule under the Toxic Substances Control Act (TSCA) to address the unreasonable risk of injury to health it has identified for conditions of use of chrysotile asbestos following completion of the TSCA Risk Evaluation for Asbestos, Part 1: Chrysotile Asbestos. TSCA requires that EPA address the unreasonable risks of injury to health and environment by rule and to apply requirements to the extent necessary so that chrysotile asbestos no longer presents such risks. Therefore, to address the unreasonable risk identified in the TSCA Risk Evaluation for Asbestos, Part 1 from chrysotile asbestos, EPA is proposing to prohibit manufacture (including import), processing, distribution in commerce and commercial use of chrysotile asbestos for chrysotile asbestos diaphragms for use in the chlor-alkali industry, chrysotile asbestos-containing sheet gaskets used in chemical production, chrysotile asbestos-containing brake blocks used in the oil industry, aftermarket automotive chrysotile asbestos-containing brakes/linings, other chrysotile asbestos-containing vehicle friction products, and other chrysotile asbestos-containing gaskets. EPA also is proposing to prohibit manufacture (including import), processing, and distribution in commerce of aftermarket automotive chrysotile asbestos-containing brakes/linings for consumer use, and other chrysotile asbestos-containing gaskets for consumer use. EPA is also proposing disposal and recordkeeping requirements for these conditions of use.
