Yesterday, the OMB’s Office of Information and Regulatory Affairs (OIRA) announced that it had received a notice of proposed rulemaking (NPRM) on “Trichloroethylene (TCE); Regulation under the Toxic Substances Control Act (TSCA); Additional Compliance Date Extensions”.
This rulemaking was not included in the 2026 Unified Agenda.
The EPA has been postponing the effective date of “certain regulatory provisions of the final rule entitled “Trichloroethylene (TCE); Regulation Under the Toxic Substances Control Act (TSCA)”” pending ‘judicial review’ since January 28th, 2025. The latest such extension was published on May 5th, 2026.
