Toxic Substances Control Act (TSCA)

The Toxic Substances Control Act (TSCA) is a U.S. federal law, passed in 1976, that gives the Environmental Protection Agency authority to regulate chemicals, including asbestos. Under TSCA the EPA can require testing, restrict uses, and ban dangerous substances. It's the law behind major EPA actions on asbestos.

Origin

Congress enacted TSCA in 1976 to fill gaps in earlier environmental laws by regulating chemicals in commerce. The EPA's 1989 asbestos ban under TSCA was largely overturned by a federal court in 1991, and TSCA was significantly amended in 2016.

Significance in Asbestos Context

For patients, TSCA's history helps show that regulators recognized asbestos hazards yet struggled for decades to ban it. The EPA's 1989 ban was mostly struck down in the 1991 Corrosion Proof Fittings case, so many asbestos products remained legal far longer than the public assumed. This regulatory timeline can matter in a case, because it documents what was known, when, and why products were still on the market during years of exposure. The 2016 amendments and later EPA rules continued the effort to restrict remaining asbestos uses.

Example Sentence

His attorneys cited the failed 1989 TSCA ban to show that asbestos products he worked with in the 1990s were still legally sold despite known dangers.

Notes

• Compare the dates of your exposure against the regulatory timeline; many products stayed legal after 1989.
• Your legal team can use regulatory records to show what manufacturers knew about asbestos hazards.
• The 2016 TSCA amendments and later EPA asbestos rules may be relevant to more recent exposures.
