TRI-Covered Industry Sectors
A facility's coverage under the Toxics Release Inventory (TRI) Program is determined by its 6-digit North American Industry Classification System (NAICS) code. NAICS is a framework by which economic units that have similar production processes are classified into the same industry by a numerical designation.

Click on the gray boxes below to determine if a certain facility is covered by TRI reporting requirements.
Note: Federal facilities are covered by TRI reporting requirements, regardless of NAICS code, due to Executive Order. The White House Council on Environmental Quality (CEQ) has reaffirmed this requirement.
The Emergency Planning and Community Right-to-Know Act originally required TRI reporting using 4-digit Standard Industrial Classification (SIC) codes. However, the Office of Management and Budget replaced the SIC code system with the NAICS code system developed by the U.S. Census Bureau, and the TRI Program adopted this system in 2006 (71 FR 32464). NAICS codes are updated every five years, and facilities currently use OMB-revised 2017 6-digit NAICS codes on their TRI reporting forms.
In November 2022, EPA finalized a rule to update the NAICS codes to reflect the 2022 revisions. Facilities are required to use 2022 NAICS codes on reports that are due to the agency by July 1, 2023. Learn more about the NAICS code update.
