On December 3, 2024, the United States Environmental Protection Agency (EPA) finalized the amendment of the new chemical procedural regulations under the Toxic Substances Control Act (TSCA). These amendment will improve the efficiency of EPA's reviewing process and align with the 2016 bipartisan TSCA Amendment under the Frank R. Lautenberg Chemical Safety for the 21st Century Act, and update the regulations based on existing policies and experience implementing the New Chemicals Program.
