TSCA "Data Call In" Proposed For 16 Priority Chemicals, Including Hydrogen Fluoride

On March 26, 2024, the U.S. Environmental Protection Agency (EPA) issued a proposed rule under Section 8(d) of the Toxic Substances Control Act (TSCA) that would require manufacturers and importers of 16 chemical substances to submit copies and lists of certain unpublished health and safety studies to EPA.¹ This is only the second time that EPA has proposed a Section 8(d) rule since the 2016 Lautenberg Amendments. It may have a significant impact on companies due to (1) the number of proposed chemicals EPA plans to include; (2) the inclusion of companies who have manufactured or imported these chemicals in the 10 year period preceding the rule; and (3) EPA's plan to move these substances forward based on this and other information for prioritization, risk evaluations, and risk management under TSCA Section 6.
