EPA Will Launch New Substantiation Functionality in TSCA Applications in CDX

Lynn L. Bergeson Carla N. Hutton

The U.S. Environmental Protection Agency (EPA) announced on October 6, 2023, that it is deploying application updates, supporting new requirements under the Toxic Substances Control Act (TSCA) Confidential Business Information (CBI) Procedural Rule, within its electronic reporting site Central Data Exchange (CDX). EPA states that the deployments will update the applications requiring CBI substantiations to be provided within the application instead of requiring substantiation documents/templates to be attached. The deployments will also require new communications for reporting TSCA Sections 12, 13, and 8(c) submissions.

According to EPA, the affected applications are located within the Chemical Safety and Pesticide Programs (CSPP) program service. The deployments will begin at 5:00 p.m. (EDT) Friday, October 13, 2023. EPA states that “[a]t that time, the applications will become unavailable. Submissions will not be accessible for editing or transmission during that time.” Access to the applications and submissions will resume at 12:00 a.m. (EDT) Monday, October 16, 2023.

More information on EPA’s TSCA CBI Procedural Rule is available in our June 12, 2023, memorandum.
