Table Name: TRI_FACILITY_SIC_HISTORY

Description: Historical representation of the Standard Industrial Classification (SIC) code or codes which best describes the activities conducted at the facility or establishment. SIC codes are 4 digit numbers used by the Bureau of Census as part of a system to categorize and track the types of business activities conducted in the United States. The first two digits of the code represent the major industry group (e.g., SIC code 25XX indicates Furniture and Fixtures) and the second two digits represent the specific subset of that group (e.g., 2511 indicates wood household furniture). EPA instructs facilities to enter their primary SIC code first. Many facilities do not report their primary SIC code first. (Data in TRI_FACILITY_SIC_HISTORY were submitted on EPA Form R or Form A, Part I, Section 4, 'Facility Identification'. See specific 'Data Source' for each column.)
