Toxics Release Inventory

  • TRI is a dataset compiled by the U.S. EPA that contains information on more than 650 toxic chemicals handled by many facilities.

  • The data is reported by facilities, made public, and has been collected since 1987.

  • Toxic chemicals – those known to cause cancer or other serious or irreversible health effects and/or have significant adverse effects on the environment.

  • The goal of EPA’s Toxics Release Inventory (TRI) Program is to empower citizens and other TRI stakeholders through information about how toxic chemicals are managed.

Toxics Release Inventory

Factors to consider with TRI data:

  • TRI covers an important subset of toxic chemicals managed at U.S. facilities, but TRI doesn't cover all chemicals or facilities.

  • TRI data reflect annual emissions and don't indicate the frequency or duration of the emissions.

  • The level of toxicity varies among the chemicals on the TRI list.

  • TRI doesn't include information about public exposure to chemicals.

  • TRI facility operations and releases are regulated under other EPA programs with requirements designed to limit human and environmental harm.

How can tribes use TRI data

TRI can help Tribes:

  • Identify sources of toxic chemical releases in or near Indian country, Alaska Native Villages, or other areas of interest to tribes;

  • Track increases or reductions of toxic chemical releases from facilities over time; and

  • Prioritize efforts to reduce pollution from facilities located on or near Indian lands.

TRI National Analysis Results

  • 46 TRI facilities located on 14 Indian country lands and Alaska Native Villages and Areas in 2011. There are 1676 facilities on or within a 10 mile buffer of these lands.

  • Total disposal or other releases from these facilities was 10.8 million pounds. On-site land disposal accounted for 89% of total disposal or other releases.

The two electric utilities on the Navajo Nation Reservation and one metal mine on the Tohono O'odham Nation of Arizona accounted for 78% of the on-site land disposal. One paper facility located on the Minnesota Chippewa Tribe's (Fond du Lac) land reported one-third (33%) of all air releases.


  • Six TRI Search tools in EPA's one stop source for environmental information.

  • Find facilities that report to TRI.

  • Create customized summaries of reported TRI information, generate release and waste management reports.

  • Review submitted TRI reporting forms and download TRI data.

New Tribal Query in Envirofacts

Query EPA’s data by proximity to tribal land


Tools to help users access and analyze the TRI data:

myRTK: for quick snapshot of facilities in your area and information about compliance history, chemicals released and potential health effects.

TRI Explorer: reports of releases, transfers, and waste managed that can be compared across facilities, chemicals, geographic areas, industries (NAICS code) or reporting years.

TRI.NetBuild customized TRI data queries which users can then download, map and analyze results with other data sources.

Geospatial tools (ArcGIS, EPA’s GeoPlatform, other mapping tools)

Tools and training to assist facilities with reporting can be found here:

Tri explorer

  • Aggregate chemical release and chemical use data

  • Includes tribal information

  • Get reports

Tri net query
TRI.NET query

  • Do queries and download data for further analysis and mapping
