EPA Withdraws Proposed Rule under TSCA for 18 Chemical Substances

Released July 8, 2025

The U.S. Environmental Protection Agency is withdrawing Proposed Significant New Use Rules (SNURs) released in June 2023 for 18 chemicals derived from plastic waste for use in producing products such as transportation fuels. After the proposed rule’s publication, EPA received comments, including adverse ones, which encouraged the agency to remand or modify the TSCA section 5(e) Order and SNURs. The proposed SNURs are being withdrawn because the Toxic Substances Control Act (TSCA) Section 5 (e) Order on which they were based was withdrawn on December 18, 2024, in response to litigation. At the time the TSCA section 5(e) Order was withdrawn, manufacture of the 18 chemicals had not commenced.
