Exponent Advises Industries on Evolving TSCA Chemical Risk Evaluations

EXPO
September 20, 2025
The Environmental Protection Agency (EPA) continues to conduct chemical risk evaluations under the Toxic Substances Control Act (TSCA), with new high-priority substances being added for assessment. In March 2024, the EPA issued a draft risk evaluation for formaldehyde, and in July 2024, it proposed designating five additional chemicals as high-priority substances, including vinyl chloride and acetaldehyde. This continuously evolving regulatory landscape, coupled with the EPA's data requirements, poses significant challenges for stakeholders in providing robust and properly documented chemical exposure data. Manufacturers must audit existing data, ensure proper documentation, and supplement information where needed, potentially requiring more sensitive sampling methods. Exponent advises companies to proactively review their exposure data and gather additional information to satisfy EPA requirements, which can help avoid costly manufacturing delays and potential penalties. The firm's expertise in toxicology, epidemiology, and industrial hygiene is critical for navigating these complex TSCA risk evaluations.
