Deadline: March 3, 2025
On January 16, 2025, the U.S. Environmental Protection Agency (EPA) announced the availability of and requested public comment on the draft scope of the risk evaluation to be conducted under the Toxic Substances Control Act (TSCA) for vinyl chloride. 90 Fed. Reg. 4738. EPA notes that under TSCA, the scope documents must include the conditions of use (COU), hazards, exposures, and the potentially exposed or susceptible subpopulations (PESS) that EPA expects to consider in conducting its risk evaluation. EPA states that the purpose of risk evaluations under TSCA is to determine whether a chemical substance presents an unreasonable risk of injury to health or the environment under the COUs, including unreasonable risk to PESS identified as relevant to the risk evaluation by EPA, and without consideration of costs or non-risk factors. Comments are due March 3, 2025. For more information, please read our full memorandum.
