EPA is developing a proposed rule to incorporate the revised 2022 North American Industry Classification System (NAICS) codes for TRI reporting purposes. The Office of Management and Budget (OMB) updates the NAICS codes every five years. OMB approved the 2022 NAICS codes on December 21, 2021 (86 FR 72277), with an effective date of January 1, 2022. EPA currently uses 2017 NAICS codes and with this proposed rule, would implement the 2022 codes for TRI Reporting Year 2022. Facilities reporting to TRI would be required to use 2022 NAICS codes on reports that are due to the Agency by July 1, 2023. This rule also proposed to update the CFR to clarify the scope of facilities required to report to TRI. The actual data required by a TRI form would not change as a result of this rulemaking, nor would the rule affect the universe of TRI reporting facilities that are required to submit reports to the Agency under the Emergency Planning and Community Right-to-Know Act section 313.
