On June 27, 2018, the U.S. Environmental Protection Agency (EPA) released a guidance document for the creation of generic names for chemical substances whose specific identities have been claimed as confidential in a Toxic Substances Control Act (TSCA) notice.

This document, "Guidance for Creating Generic Names for Confidential Chemical Substance Identity Reporting under the Toxic Substances Control Act", provides detailed guidelines and examples for creating structurally descriptive generic names for class 1 organic, class 2 organic, and inorganic chemical substances. Specifically, the document provides advice on how certain chemical groups, parent structures, and other structural elements can be masked when creating a generic chemical substance name. The generic name will be included in the TSCA Chemical Substance Inventory and available to the public.

Note that this guidance document has replaced the guidance previously published by EPA in 1985. EPA will review generic chemical substance names submitted in TSCA filings for consistency with this updated guidance.

The EPA guidance document is available for review here. Additionally, EPA is accepting public comments on the document until August 27, 2018, which can be submitted here. For any additional questions, please contact your local Trinity office at (800) 229-6655.
