Another Delay for EPA’s TCE Requirements

EPA has once again postponed the effective date for certain provisions of its risk management rule for the solvent trichloroethylene, or TCE. Promulgated in December 2024, the rule prohibits all uses of TCE, some within one year. Other uses were granted temporary exemptions under section 6(g) of the Toxic Substances Control Act that allow the use to continue but with workplace restrictions. These restrictions are the subject of lawsuits that have prompted EPA to repeatedly extend their implementation deadline. The latest extension establishes Feb. 17, 2026, as the effective date for the section 6(g) restrictions.

A summary of the legal challenges that led to the extensions appears in the Federal Register. For more information, refer to EPA’s web page on risk management for TCE.
