On June 23, 2025, the U.S. Environmental Protection Agency (EPA) announced a 60-day extension of the postponement of specific regulatory provisions from its final rule on trichloroethylene (TCE) under the Toxic Substances Control Act (TSCA). The extension applies to conditions affecting uses of TCE which are covered by TSCA Section 6(g) exemptions. 

Additional Time for Compliance and Feedback 

The original rule, published on December 17, 2024 (89 FR 102568), included new requirements for how TCE can be used, even in cases where exemptions apply. These requirements were already postponed once, and as of June 20, 2025, EPA has further delayed their start date to August 19, 2025. 

This extension allow EPA to consider implementation issues and review any concerns raised by stakeholders. It also gives affected businesses more time to prepare for compliance.
