EPA Extends Submission Deadline for Health and Safety Studies on Fifty Chemicals

WASHINGTON (September 24, 2021) - Today, EPA is extending the submission deadline for manufacturers (including importers) of 50 chemicals to report data from certain unpublished health and safety studies to EPA. The deadline for the reporting rule was originally September 27, 2021, and EPA has extended the deadline until December 1, 2021 for 20 of the 50 chemicals and to January 25, 2022 for 30 of the 50 chemicals.

In June, EPA announced the addition of 50 chemicals to the TSCA section 8(d) Health and Safety Data Reporting Rule. This rule requires manufacturers (including importers) of these chemicals to submit health and safety studies, as well as unpublished studies on environmental effects and occupational, general population, and consumer exposure for these chemicals. These health and safety studies will help inform EPA’s prioritization and risk evaluation of chemicals under TSCA, furthering the agency’s efforts to protect human health and the environment.

The 50 chemicals include:

  • Twenty chemicals designated by EPA as high-priority substances and currently undergoing risk evaluation under TSCA. The deadline for manufacturers to submit studies on these chemicals will be December 1, 2021. This deadline ensures that health and safety studies will be received in time for use in risk evaluations on these chemical substances.
  • Thirty organohalogen flame retardants being evaluated for health risks by the Consumer Product Safety Commission (CPSC). The deadline for manufacturers to submit studies on these chemicals will be January 25, 2022.
