TRI Basic Plus Data Files: Calendar Years 1987 - 2012

EPA has been collecting TRI data since 1987. Files available here are .txt files bundled into a .zip format. Collectively, these files contain all the data submitted on the TRI Reporting Form R or Form A Certification Statement by facilities in a selected state. See the TRI Basic Plus Data File Documentation for detailed descriptions of the data fields contained in these files.

The seven file types in the TRI Basic Plus data files include the following:

  • 1: Facility, Chemical, Releases and Other Waste Management Summary Information
  • 2a: Detailed Source Reduction Activities and Methods
  • 2b: Detailed On-Site Waste Treatment Methods and Efficiency
  • 3a: Details of Transfers Off-site
  • 3b: Details of Transfers to Publicly Owned Treatment Works (POTW)
  • 4: Details of Facility Information
  • 5: Additional Information on Source Reduction, Recycling and Pollution Control

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