Toxics Release Inventory (TRI) Program

2009 TRI National Analysis Basic Data Files

The downloadable data files on this webpage contain the RY 2009 TRI information originally made available in the fall of 2010. Please note that these files don't reflect any data revisions or withdrawals submitted by facilities since the fall of 2010. If you're looking for the most current 2009 TRI data, please see the TRI Basic Data Files or TRI Basic Plus Data Files webpages.

Each TRI Basic Data File contains approximately 100 data fields. The data are presented in comma-delimited ASCII text. This format loads easily into many spreadsheets and database software applications. See the TRI Basic Data Files Guide for RY 2009 (PDF) for instructions on how to load the data files into MS Excel and MS Access. Many of the descriptions refer to the TRI Form R and Form A Certification Statement. These are the forms that facilities use to submit data to the TRI Program. The TRI Reporting Forms and Instructions document contains the actual forms and instructions for completing them, as well as complete lists of values for the data fields.

The general types of data in TRI Basic data files include the following:

  • Facility Name, Address, Latitude & Longitude Coordinates, and SIC or NAICS codes
  • Chemical Identification and Classification Information
  • On-site Release Quantities
  • Publicly Owned Treatment Works (POTW) Transfer Quantities
  • Off-site Transfer Quantities for Release/Disposal and Further Waste Management
  • Summary Pollution Prevention Quantities (Section 8 of the Form R)

NOTE: Quantities of dioxin and dioxin-like compounds are reported in grams; all other chemicals are reported in pounds.
