On March 11, 2009 the EPA issued revisions to the Toxics Release Inventory (TRI) reporting requirements. These changes affect TRI reports due July 1, 2009. The changes require that all reports on persistent, bioaccumulative, and toxic (PBT) chemicals be submitted on Form R. For all other chemicals Form A may be used only if the annual reporting amount is 500 pounds or less and the chemical was manufactured, processed or otherwise used in an amount not exceeding 1 million pounds during the reporting year. These changes reverse the reduced reporting burden implemented by the EPA in 2006. TRI-ME software and other reporting assistance materials are currently being revised and should be available soon. More information is available on EPA's Web site.
