The Environmental Protection Agency has announced an extension to the comment period for the new procedural regulations of the Toxic Substances Control Act. This extension will take effect on July 19, 2023, as per the Federal Register notice. The amendments aim to align the regulatory text with the Frank R. Lautenberg Chemical Safety for the 21st Century Act, update the regulations based on existing policies and experience, and improve the effectiveness of the EPA’s review procedure for new chemicals. The proposed rule changes will reduce the need to redo risk assessments by improving the information initially submitted in new chemical notices, which will shorten the review period.

However, per- and poly-fluoroalkyl substances (PFAS) are not covered by these exemptions, and certain persistent, bio-accumulative, and toxic (PBT) chemical substances are also not eligible. The proposed Low-volume exemptions (LVE) and low release and exposure exemptions (LoREX) restrictions have been modified, and EPA approval of an exemption notice will now be required before manufacturing starts.       

Comments are due August 8, 2023
