EPA Launches New Paperless Communication Application for TSCA Data in Central Data Exchange

For Release: May 11, 2021

The U.S. Environmental Protection Agency (EPA) has launched a new application in the Central Data Exchange (CDX), the agency's electronic reporting site, that will allow users to submit certain communications under the Toxic Substances Control Act (TSCA) electronically. The new application provides users with a faster, secure, and more convenient way to comply with reporting requirements under TSCA and is expected to be used for hundreds of individual communications every year.

The application is located within the Chemical Safety and Pesticide Programs (CSPP) dataflow and supports numerous types of communications including: General Confidential Correspondence, Requests for Chemical Information, Pre-manufacture Notice (PMN) Corrections for Submissions made Prior to 2016, and Copy of Record Requests. Previously, these types of communications were required to be sent to the agency in hard copy. While the agency will continue to accept paper documents, EPA recommends submitting communications under TSCA electronically when possible since paper communications could take longer to process.
