The U.S. Environmental Protection Agency (EPA) announced on January 24, 2024, that it is extending the review period for confidential business information (CBI) claims for specific identity of all active chemical substances listed on the confidential portion of the Toxic Substances Control Act (TSCA) Inventory submitted to EPA under TSCA. 89 Fed. Reg. 4605. EPA states that it “has determined that an extension of the statutory review period for the review of CBI claims under TSCA are necessary to allow the Agency to complete the required reviews under TSCA.” According to EPA, the additional time is necessary “given the volume of submissions that require review, information technology issues, and other legal and administrative delays that have affected the review process.” EPA extended the review period to February 19, 2025. As this extended deadline approaches, EPA may further extend the deadline as necessary to complete the reviews.
