On June 13, 2025, the U.S. Environmental Protection Agency (EPA) issued a final rule in the Federal Register (90 FR 24977), establishing Significant New Use Rules (SNURs) under the Toxic Substances Control Act (TSCA). The rule applies to specific chemical substances that were previously submitted through Premanufacture Notices (PMNs) and are also subject to EPA Orders under TSCA. 

Mandatory Notification for New uses 

The rule requires any individual or company intending to manufacture (including import) or process these substances for a “significant new use” to notify EPA at least 90 days in advance. This notification allows EPA to assess potential risks and determine if restrictions are needed before the activity begins. 

Effective and Promulgation Dates 

 The rule will take effect on August 12, 2025. For judicial review purposes, the rule will be officially promulgated at 1 p.m. EST on June 27, 2025. 

Codification and Compliance 

These SNURs are codified under Title 40 CFR Parts 9 and 721. The affected substances are already subject to risk management provisions in TSCA orders, including exposure control and hazard communication measures. The SNURs ensure that any new or expanded uses beyond these existing terms are properly reviewed by EPA. 

Access to Supporting Documents 

Supporting documents and the full rule are available in Docket EPA-HQ-OPPT-2023-0328 on Regulations.gov, and the rule was notified internationally under WTO symbol G/TBT/N/USA/2125/Add.1.

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.

The rule will take effect on August 22, 2025, and is scheduled to be officially announced in the Federal Register on July 7, 2025. The final rule is available in the Federal Register (90 FR 26437).  Relevant documents can also be accessed via Regulations.gov by searching the docket number (EPA-HQ-OPPT-2024-0077).
