EPA Toxics Release Inventory National Analysis

Description

This resource provides access to data from the EPA Toxics Release Inventory, which provide self reported information on toxic chemical releases and pollution prevention activities from industrial and federal facilities. There are several types of information provided by the resource, including tools for tracking releases over time, exploring individual facility releases, summaries across sectors and locations, health impacts from TRI releases, and databases of chemical releases.

Questions this resource can help answer

What are toxic releases for sources in and around my city?
What is the trend in TRI releases for specific source categories for my city?

How do I use this resource?

Several tools were not working as of January 2026. The Mapping TRI (accessed at the bottom row of the tiles) is functioning and can be used to examine information on TRI releases in different states and communities. You can click on any state to open a summary. In the summary, there will be an embedded map with county information. You can zoom in further and get zip code level information, and further to get specific facility information. At the bottom of the state and county reports, there are buttons to click to download the TRI data.

Pro tips

Note that the National Analysis data visualization dashboard does not appear to be functioning. However, the Mapping TRI tool, accessed is still functional.

Methodology

Toxic releases are self reported by covered sources. Facilities must report the quantities of TRI-listed chemicals they release into the environment and send off site for disposal or other release.

Model

CoST

The Control Strategy Tool (CoST), developed in 2008, is part of EPA's Emissions Modeling Framework (EMF). CoST is used to estimate emissions reductions and engineering costs associated with control strategies applied to point and area sources of air pollutant emissions to support the analyses of air pollution policies and regulations.

Model

MOVES

EPA's MOtor Vehicle Emission Simulator (MOVES) is a state-of-the-science emission modeling system that estimates emissions for mobile sources at the national, county, and project level for criteria air pollutants, greenhouse gases, and air toxics, available under EPA's Open Source Software policy.

SMOKE

SMOKE is primarily an emissions processing system designed to create gridded, speciated, hourly emissions for input into a variety of air quality models such as CMAQ, REMSAD, CAMX and UAM. SMOKE supports area, biogenic, mobile (both onroad and nonroad), and point source emissions processing for criteria, particulate, and toxic pollutants. For biogenic emissions modeling, SMOKE uses the Biogenic Emission Inventory System. SMOKE is also integrated with the on-road emissions model MOVES.
