EPA Toxic Release Inventory (TRI) Report

EPA Toxic Release Inventory (TRI) Report – Form R  – Due July 1, 2011

The Form R report is required if any of the over 600  listed chemicals or substances are used as raw material, or as an ingredient in a material, over the reporting threshold for that chemical.

Common and often overlooked reportable materials include:

  • Lead
  • Metals including Copper, Chrome, Nickel, Zinc (stainless steel includes several reportable materials)
  • Nitric Acid
  • Sulfuric Acid

The annual public burden related to Form R reporting, as stated by the EPA, is estimated to average 29.6 hours per response for non-PBT chemicals and 51.3 hours per response for PBT chemicals.

The penalties for failing to submit this report on time are be significant, it is rare that non filers are not assessed a fine.  The EPA does have some provisions for self-disclosure of non compliance in which fines can be eliminated provided certain conditions are met.
