The Environmental Protection Agency (EPA or Agency) is amending the Toxic Substances Control Act (TSCA) Chemical Data Reporting (CDR) regulations to extend the submission deadline for 2024 reports to November 22, 2024. This extension is for the 2024 submission period only. The TSCA CDR regulations require manufacturers (including importers) of certain chemical substances included on the TSCA Chemical Substance Inventory (TSCA Inventory) to report data on the manufacturing, processing, and use of the chemical substances.
