Asbestos Part 2: Legacy Uses and Associated Disposals of Asbestos; Regulation under the Toxic Substances Control Act (TSCA)

This rulemaking will address the unreasonable risk of injury to health from asbestos, as a chemical substance, identified by EPA in a risk evaluation completed under TSCA section 6(b) that focused on legacy uses of asbestos and associated disposals, asbestos-containing talc, and types of asbestos fibers other than chrysotile. Section 6 of the Toxic Substances Control Act (TSCA) requires that EPA, when it determines in a TSCA risk evaluation that a chemical presents an unreasonable risk of injury to health or the environment, apply one or more requirements under TSCA section 6(a) by rule to the extent necessary so the chemical substance no longer presents an unreasonable risk. EPA has bifurcated the risk management of asbestos into two parts; Part 1: Chrysotile Asbestos and Part 2: Legacy Uses and Associated Disposals of Asbestos. EPA completed its Part 1 risk evaluation and rulemaking activities for Chrysotile Asbestos. EPA’s Part 2 risk evaluation for asbestos, describing the conditions of use and presenting EPA’s determination of unreasonable risk, and related materials for that risk evaluation, are available in docket EPA-HQ-OPPT-2021-0254
