EPA’s new policy may result in public disclosure of confidential business information if confidentiality is not properly claimed.

By Julia A. Hatcher, Ann Claassen, and Stijn van Osch

The US Environmental Protection Agency (EPA) announced on July 15, 2019 that, beginning August 15, 2019, EPA would no longer provide notices of deficiency to businesses that submit procedurally flawed confidential business information (CBI) claims under the Toxic Substances Control Act (TSCA). Instead, EPA will only send a notice that the agency does not consider such information confidential, and will make such information available to the public. This policy change, which EPA published in the Federal Register on July 16, means that businesses should take care to provide complete and accurate substantiation for CBI, or risk public disclosure of confidential information.
