Toxics Release Inventory (TRI) Program

TRI Data and Tools

The TRI Program tracks the management of toxic chemicals that may pose a threat to human health and the environment. Facilities in certain industry sectors report annually the volume of toxic chemicals managed as waste--recycled, treated or burned for energy recovery--as well as disposed of or otherwise released into the environment.

The complete 2017 TRI dataset is now available in TRI Explorer, the TRI P2 Search Tool, in the Envirofacts TRI searches, and in the downloadable TRI data files.

More Information to Help You Use TRI Data

Download data from TRI reporting forms for any reporting year since 1987. Recommended for users with extensive knowledge of TRI data.

  • Basic Data Files: Frequently requested data elements. National, federal, tribal and state-level data files grouped by reporting year.
  • Basic Plus Data Files: National-level data files containing all data elements reported on the Reporting Form R, grouped by reporting year. 
  • Dioxin, Dioxin-Like Compounds and TEQ Data Files: Dioxin mass quantity data reported on Reporting Form R Schedule 1, with associated Toxic Equivalency data elements. National-level data files by current reporting year.

Use TRI data in conjunction with other EPA data sources for comparative analysis.

  • TOXMAP: Explore environmental health data related to Superfund sites and TRI-reporting facilities using GIS-based maps developed by the National Library of Medicine.
  • DMR (Discharge Monitoring Report) Pollutant Loading Tool: Compare DMR and TRI release data. Determine what pollutants are being discharged into waterways, and by which companies.
  • Enforcement and Compliance History Online (ECHO): Search EPA and state compliance and enforcement records for air, water, and hazardous waste regulations, including contextual data for TRI and other programs.
  • Enviromapper: Generate maps that contain environmental information, including TRI information. Add features such as schools, streets, and water bodies to view the information in context.
  • TRI-CHIP (TRI Chemical Hazard Information Profiles): Access and analyze toxicity information from multiple data sources for chemicals included on the TRI list.
  • TRI metadata: Get reference information to support use and understanding of TRI data. Includes lists of chemical categories, associated health effects, covered industry codes, and codes used on reporting forms.
