Assessing and Managing Chemicals under TSCA

Electronic Reporting Requirements for Certain Information under the Toxic Substances Control Act

On December 4, 2013 EPA finalized a rule to require electronic reporting of certain information submitted to the Agency under the Toxic Substances Control Act (TSCA). The final rule follows two previous rules requiring similar electronic reporting of information submitted to EPA (for TSCA Chemical Data Reporting and for Pre-Manufacture Notifications), and is intended to save time, improve data quality and increase efficiency.

Specifically, the final rule requires electronic submission of data and other information for:

  • TSCA section 4 test rules,
  • TSCA section 5 Notices of Commencement of Manufacture or Import ("NOCs") and support documents relating to section 5 notices sent to EPA before April 6, 2010,
  • TSCA section 8(a) Preliminary Assessment Information Rule (PAIR) submissions, and
  • TSCA section 8(d) health and safety studies.

Submitters will be required to use EPA’s Central Data Exchange (CDX), the Agency's electronic reporting site. Learn more about CDX.

Note: Users who have previously registered with CDX to submit data under TSCA section 5 or for the Toxics Release Inventory TRI-ME Program are able to add "Submission for Chemical Safety and Pesticide Program (CSPP)" to their current registration.
