EPA is amending the Toxic Substances Control Act (TSCA) Chemical Data Reporting (CDR) regulations by extending the submission deadline for 2012 reports from June 30, 2012 to August 13, 2012. This is a one-time extension for the 2012 submission period only. The CDR regulations require manufacturers and importers of certain chemical substances included on the TSCA Chemical Substance Inventory (TSCA Inventory) to report current data on the manufacturing, processing, and use of the chemical substances.
