EPA Proposes Major Expansion of TSCA Inventory Update Reporting Rule

EPA has proposed changes to TSCA's Inventory Update Reporting Rule (IUR) that would significantly increase the amount of information required to be reported, the frequency of reporting, and the number of companies that would have to file an IUR report.

Currently, the IUR rule requires U.S. companies to file a report every five years for each chemical on the TSCA Inventory that they manufacture or import. The next report is due between June and September 2011 for the calendar year 2010. The threshold for filing is 25,000 pounds during the preceding calendar year. Additional information on domestic processing and use has to be reported if a company manufactures or imports more than 300,000 pounds during that year. A separate report is filed for each chemical that exceeds the threshold at each plant location.
