June 14, 2006—Owners and operators of facilities subject to Toxics Release Inventory (TRI) reporting must identify their principal business activities using North American Industry Classification System (NAICS) codes beginning with reports due July 1, 2007, for releases and other waste management activities for the 2006 calendar year, says the US Environmental Protection Agency (EPA).
In the past, principal business activities were reported using Standard Industrial Classification (SIC) codes, so identifying industrial codes is not a new requirement. EPA is not adding or deleting industry groups subject to reporting requirements, but rather is simply identifying the NAICS codes that are subject to TRI.
The Office of Management and Budget plans to update the NAICS system every five years. The next update is scheduled for 2007. TRI-covered NAICS codes, if affected by these updates, will be revised accordingly, says EPA.
Additional information to help facilities convert from SIC to NAICS is available from EPA.
