EPA Allows More Time for Data Reporting on 16 Chemicals

A rule issued last week by EPA extends the deadline for manufacturers and importers of 16 chemicals to provide the agency with data from unpublished health and safety studies. The rule, which became effective on March 13, extends the reporting deadline for one of the chemicals, vinyl chloride, by 90 days to June 11, 2025. Manufacturers and importers of the other 15 chemical substances covered under the rule now have an additional 180 days, until Sept. 9, 2025, to provide EPA with the required information. In addition to data from health and safety studies, the agency is also requiring affected entities to submit unpublished studies related to environmental effects and exposures to workers, consumers, and the general population. According to EPA, “[t]hese health and safety studies will help inform EPA’s prioritization, risk evaluation and risk management of chemicals under TSCA,” the Toxic Substances Control Act.

Benzene, bisphenol A, hydrogen fluoride, and styrene are among the substances for which manufacturers and importers must report data. Five of the 16 chemicals—MBOCA, acetaldehyde, acrylonitrile, benzenamine, and vinyl chloride—were previously identified by EPA as high-priority substances for risk evaluation.
