On May 12, 2022, the U.S. Environmental Protection Agency (EPA) proposed new and amended requirements concerning the assertion and treatment of confidential business information (CBI) claims for information reported to or otherwise obtained by EPA under the Toxic Substances Control Act (TSCA). 87 Fed. Reg. 29078. The Frank R. Lautenberg Chemical Safety for the 21st Century Act (Lautenberg Act) amendments to TSCA in 2016 included many new provisions concerning the assertion, EPA review, and treatment of confidentiality claims. EPA proposes procedures for submitting such claims in TSCA submissions and addresses issues such as substantiation requirements, exemptions, electronic reporting enhancements (including expanding electronic reporting requirements), maintenance or withdrawal of confidentiality claims, and provisions in current rules that are inconsistent with amended TSCA. The proposed rule also addresses EPA procedures for reviewing and communicating with TSCA submitters about confidentiality claims. Comments are due on or before July 11, 2022. For more information, please read the full memorandum.
