Procedures for Review of CBI Claims for the Identity of Chemicals on the TSCA Inventory; Revisions to the CBI Substantiation Requirements

Résumé

In response to a recent federal circuit court decision, EPA is proposing revisions to existing and proposed substantiation requirements for certain confidential business information (CBI) claims made under the Toxic Substances Control Act (TSCA). Specifically, EPA is proposing two additional questions that manufacturers and processors would be required to answer to substantiate certain CBI claims for specific chemical identities; and is proposing procedures for manufacturers and processors to use in amending certain previously- submitted substantiations to include responses to the additional questions. These proposed revisions supplement the proposed rule issued in the Federal Register of April 23, 2019, and would amend the TSCA Inventory Notification (Active-Inactive) Requirements rule promulgated in the Federal Register of August 11, 2017.
