EPA Requires Reporting on Health and Safety Data for Fifty Chemicals

WASHINGTON (June 29, 2021) — Today, EPA finalized a rule under the Toxic Substances Control Act (TSCA) to require manufacturers (including importers) of 50 chemicals to report data from certain unpublished health and safety studies to EPA. In addition to health and safety studies, manufacturers are also required to submit unpublished studies on environmental effects and occupational, general population, and consumer exposure for these chemicals.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 added to the TSCA section 8(d) Health and Safety Data Reporting Rule by this action include:

  • Twenty chemicals designated by EPA as high-priority substances and currently undergoing risk evaluation under TSCA. These studies will be used to inform the ongoing risk evaluations to determine if there are any unreasonable risks to health or the environment under their current conditions of use.
  • Thirty organohalogen flame retardants being evaluated for health risks by the Consumer Product Safety Commission (CPSC)EXIT. Preliminary searches show that little or no health and safety information is available for these chemicals. The information collected under this rule will help inform TSCA activities like prioritizing chemicals for risk evaluation and new chemical reviews. The information also will assist CPSC in its review of these chemicals in consumer products.

EPA is taking this action under the recommendation of the Interagency Testing Committee (ITC), an independent advisory committee that makes recommendations to the EPA Administrator on prioritizing and selecting chemicals for testing. The ITC added EXITthe 50 chemicals to its “Priority Testing List,” recommending that EPA gather additional data about the health and environmental effects of these chemicals.
