Column Name: SOURCE

Description: Indicates whether the NAICS code on a TRI submission was reported or assigned. In reporting years 1987 through 2005, the TRI program collected Standard Industrial Classification (SIC) codes on submissions to identify the primary business lines of reporting facilities. In reporting year 2006, TRI switched to the North American Industrial Classification System (NAICS) codes. To facilitate the comparison of TRI data across these two TIME periods, NAICS codes were assigned to submissions in reporting years 1987-2005. All forms from 1987 through 2005 should have assigned primary NAICS codes. All forms after reporting year 2005 should have reported NAICS codes. The list of values for this data element are:

Value	Description
