TRI BannerTRI icon

The Toxics Release Inventory (TRI) Search retrieves data from the TRI database in Envirofacts.

Use TRI Search  to access a variety of reports for every facility that has reported to EPA since 1987.  You may narrow your search  based on facility name/ID, geographic location, tribal identifier, industry classification, or chemical names/CAS numbers.

For each facility listed in the search results, you can go directly to a report containing:

  • Names of reported chemicals and the most recent year of TRI reporting (TRI Facility Report)
  • Indications of any newly implemented source reduction activities and text descriptions other pollution prevention practices (TRI Facility Report)
  • Waste management methods and trends (TRI Facility Report)
  • Trends in environmental releases of reported chemicals (TRI Facility Report)
  • Information about transfers of waste containing TRI chemicals (TRI Facility Report)
  • Basic environmental permit and compliance information (TRI Facility Report)
  • Details about pollution prevention and source reduction activities implemented at the facility (P2 Report)
  • Estimates of potential relative risks posed by the facility and its industry sector (Risk Screening Report)
  • Access to individual Form Rs or Form As

Facility Selection

Geography Search

Enter a partial value for any geography option except for the state value. For city and county, you must enter the state value. We strongly recommend that you enter a small geographical area to begin the search since Envirofacts contains a large number of facilities.

Tribal Search

Search for facilities by Tribe. Enter the Bureau of Indian Affairs (BIA) Tribal Code or the Tribe name. The drop down list for BIA Tribal Codes only contains BIA Tribal Codes that facilities have reported to TRI. These search options are available only when using TRI facility information to perform the facility search.

Facility Industrial Classification Search

Select a search option from the drop down menu. For the “Equal to” option enter a 4-digit SIC code. For “Beginning with” or “Containing” enter up to 4 digits.


Select a search option from the drop down menu. For the “Equal to” option enter a 4 to 6-digit NAICS code. For “Beginning with” or “Containing” enter up to 6 digits.


Industry Code - Select an industry code and description from the drop down menu.

Chemical Name Search

Enter the chemical name or lookup the appropriate CAS number by clicking on the "Lookup Pollutant codes and CAS Numbers" link. If both Chemical Name and CAS number are entered, only CAS Number will be used in the search.
