North American Industry Classification System (NAICS) Codes in TRI Reporting
This list of TRI-covered NAICS codes was developed using 2002 NAICS codes and has been updated to show revisions in NAICs codes affected by the 2007 revision update. The list of industries subject to reporting under the TRI program is commonly divided into two groups called Original and New. Original Industries are those covered under the original EPCRA legislation. New Industries are those which were added by regulation in 1998. For more information on NAICS and complete SIC to NAICS crosswalk tables, please go to the Census Bureau NAICS Web site. 
The NAICS is reviewed every five years for potential revisions so that the classification system can keep pace with the changing economy. The codes were last updated on March 16, 2006, when OMB published a final notice of the NAICS revision for 2007 (71 Federal Register 28532) that states that “data published for reference years beginning on or after January 1, 2007, should be published using the 2007 NAICS United States Codes.” EPA will publish a rule implementing use of the 2007 NAICS codes for 2008 due by July 1, 2009.
