The U.S. Environmental Protection Agency (EPA) announced on January 15, 2021, that it has issued test orders under Section 4 of the Toxic Substances Control Act (TSCA) to obtain additional data on nine of the next 20 chemicals undergoing risk evaluation. EPA states that after reviewing the available data on these chemicals, it needs additional data and is using its TSCA test order authority to require companies to develop and submit information on environmental hazard and inhalation and dermal exposures for workers. According to EPA, companies subject to the test orders may provide EPA with existing data or conduct new tests. Companies may also form consortia to consolidate costs and burden and to avoid unnecessary duplication of testing. For more information, please read the full memorandum.
