EPA 2024 TSCA Chrysotile Ban Rule

This is the final rule issued by the U.S. Environmental Protection Agency in March 2024 under the Toxic Substances Control Act (TSCA) that bans the ongoing use, manufacture, processing, distribution, and import of chrysotile asbestos in the United States. It is the first federal action in more than 30 years to prohibit any form of asbestos and targets the last remaining commercial uses, including chlor-alkali industry diaphragms, sheet gaskets, brake blocks, and certain aftermarket automotive friction products. The rule phases out these uses over staggered deadlines ranging from six months to twelve years, depending on the product category.

Origin

The rule arose from the 2016 Frank R. Lautenberg Chemical Safety for the 21st Century Act, which amended TSCA and required EPA to evaluate high-priority existing chemicals. Asbestos was named one of the first ten chemicals for risk evaluation, and after the 2020 Part 1 risk evaluation found unreasonable risk from chrysotile, EPA proposed the ban in 2022 and finalized it on March 18, 2024. It followed the 1989 EPA asbestos ban that had been largely overturned by the Fifth Circuit in Corrosion Proof Fittings v. EPA (1991).

Significance in Asbestos Context

For patients and families, this rule is important context showing that asbestos exposure in the United States did not end decades ago. Chrysotile was still being legally imported and used in industrial settings until 2024. People diagnosed today with mesothelioma, lung cancer, or asbestosis may have been exposed in workplaces such as chlor-alkali plants, auto repair shops, or oil refineries well into the 21st century, which directly affects how recently a viable exposure could have occurred and which defendants may be responsible. The rule also strengthens the broader evidentiary picture in litigation: EPA's formal finding of 'unreasonable risk' from chrysotile undermines longstanding industry arguments that chrysotile is safer than amphibole asbestos or that controlled use was adequate. Patients should know that the rule does not address legacy asbestos already in buildings, pipes, insulation, and consumer products, and it does not cover the five other regulated asbestos fibers, so exposure risks and legal claims involving older products remain active.

Example Sentence

When the client described working as a mechanic on imported brake parts through 2022, his attorney pointed to the EPA 2024 TSCA Chrysotile Ban Rule as evidence that the federal government had finally acknowledged the very exposures his employer told him were safe.

Notes

• If your work history includes a chlor-alkali plant, oil refinery, paper mill, brake or gasket manufacturer, or auto repair work after 2000, tell your attorney. These are the exact industries the 2024 rule targeted and confirms were still using chrysotile.
• Preserve any product packaging, MSDS or SDS sheets, purchase records, or shipping manifests showing asbestos-containing materials in use after 1990, as these become more persuasive in light of EPA's recent findings.
• Ask your treating physician to document a full occupational and exposure history in your medical record; recent exposures are still legally and medically relevant even though many people assume asbestos was banned long ago.
• Be aware that this rule does not require removal of asbestos already installed in buildings, machinery, or consumer goods, so renovation, demolition, and maintenance exposures continue to drive new cases.
