A business must meet ALL three of the following criteria for any particular year to be subject to TRI requirements:

    • The facility is in one of the covered industries:
      • Manufacturing
      • Metal Mining
      • Coal Mining
      • Electric Utilities (that combust coal and/or oil)
      • Commercial Hazardous Waste Treatment and Disposal
      • Chemical and Allied Products Wholesale
      • Petroleum Bulk Terminals and Plants
      • Solvent Recovery Services; AND
    • The facility has 10 or more full-time employees (or the equivalent of 20,000 hours per year); AND
    • It manufactures, imports, processes, or otherwise uses any of the EPCRA section 313 chemicals in amounts greater than the threshold quantity.


Threshold quantities that trigger reporting requirements are

    • 25,000 pounds manufactured or processed or 10,000 pounds otherwise used, except for some Persistent Bioaccumulative Toxic (PBT) Chemicals.
      • See the EPA TRI information on toxic chemicals subject to EPCRA Section 313 reporting requirements.

  • Facilities that meet the reporting requirements submit a reporting form to the EPA and to the HEER Office by July 1 for the preceding calendar year inventory.
  • A TRI reporting form is submitted for each TRI chemical the facility has manufactured, imported, processed, or otherwise used in amounts exceeding the thresholds.
  • The preferred method for reporting TRI forms is via the EPA Central Data Exchange (using the toxic release inventory-made easy tool).
