Toxics Release Inventory (TRI) Program

Adoption of 2017 North American Industry Classification System (NAICS) Codes for TRI Reporting

Rule Summary

On December 26, 2017, EPA finalized a rule to update the list of NAICS codes used to classify facilities subject to reporting under Section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA). The ECPRA legislation established the Toxics Release Inventory (TRI). Facilities that meet TRI reporting requirements are now required to use 2017 NAICS codes on TRI reporting forms, beginning with reporting forms that are due on July 1, 2018 (covering releases and other waste management activities at facilities for the 2017 calendar year).

Rule History

The Office of Management and Budget (OMB) revises NAICS codes every five years, at which time the list of NAICS codes covered by the TRI Program must also be updated. OMB last updated the NAICS codes in 2017. On August 17, 2017, EPA published both a direct final rule and a proposed rule to update the TRI Program's NAICS code list. On November 14, 2017, EPA withdrew the direct final rule due to an adverse comment received during the public comment period. With the December 26, 2017, final rule, EPA has finalized the rule for use starting with Reporting Year 2017.
