Toxics Release Inventory (TRI) Program
TRI information is available through a variety of reports, query tools and data files.
Factors to Consider About TRI
- 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.
- Quantities reported by TRI facilities reflect chemicals released into the air and water and chemicals managed through recycling, energy recovery, treatment and disposal.
- 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.
TRI National Analysis Reports
Each year, EPA publishes documents and webpages that provide analysis and interpretation of the most recent TRI data, including national and local trends of toxic chemical releases to the environment. Geo-specific analyses include Indian Country and Alaskan Native Villages, large aquatic ecosystems, urban communities, and state factsheets. National Analysis documents are available online and many are in Spanish.
Tools for TRI Data Access and Analysis
There are many tools available for accessing and analyzing TRI data, including:
- Six TRI Search tools in Envirofacts, EPA's one stop source for environmental information. With these tools you can 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.
TRI Explorer: Generate reports on releases, transfers, and waste managed that can be compared across facilities, chemicals, geographic areas, industries (NAICS code) or reporting years. Users may also generate State Reports.
TRI Search: Find TRI facilities that have reported to TRI since 1987.
TRI Form R Search: Review TRI information submitted on Form R.
TRI Form R & A Download: Download TRI Form R and Form A data elements.
TRI EZ Search: Create a report on a single subject area using a limited set of TRI data elements.
TRI Customized Search: Create a report on multiple subject areas using the most comprehensive set to TRI data elements.
- myRTK (my Right-to-Know): Geographically view TRI facilities in a selected area and obtain summary facility information including compliance data, quantities of chemicals released and associated potential health effects. This is a simple tool designed for mobile devices in English and Spanish.
- TRI.NET: Build customized TRI data queries using menus or an adhoc query option; users can download, map or overlay results with other data sources. This is a downloadable application.
Other EPA Tools that use TRI data for comparative analysis and provide information on potential health effects:
- TRI Comparative Analysis Tool: Compare TRI facility records with those collected under EPA air, water and waste programs.
- TRI-CHIP (TRI Chemical Hazard Information Profiles): Access and analyze toxicity information from multiple data sources for chemicals included in the TRI list. This is a downloadable MS Access database.
- Enviromapper: Generate maps that contain environmental information, including TRI information, for an area of interest. Users may also add features such as schools, streets, and water bodies to view the information in context. This is a web-based interactive mapping tool.
- RSEI (Risk-Screening Environmental Indicators): Analyze trends or rankings of toxic chemicals released to the environment by regions, states, counties, industries, facilities, chemicals or release pathways. This is downloadable screening tool that combines TRI release data with other risk factors.
- DMR (Discharge Monitoring Report) Pollutant Loading Tool: Determine who is discharging into waterways, what pollutants they are discharging and how much, and where they are discharging. The tool incorporates wastewater pollutant discharge data from TRI.
Downloadable Data Files
Data files are available for all previous TRI reporting years. Use of these files is recommended for those with extensive knowledge of TRI data.
- Basic Data Files: Contain the most frequently requested data elements from the TRI reporting forms.
- Basic Plus Data Files: Contain all of the data elements from the TRI reporting forms.
Other Toxic Chemical Data Sources
- EPA's Integrated Risk Information System (IRIS): View EPA human health assessment information for more than 550 chemical substances. The IRIS database contains descriptive and quantitative carcinogenic and non-carcinogenic health risk information.
- TOXNET (TOXicology Data NETwork): Access and easily search a cluster of databases covering toxicology, hazardous chemicals, environmental health and related areas. TOXNET is provided by the National Library of Medicine (NLM).
- ToxMap: Visually explore TRI and Superfund Program data by location, chemical, release medium/amount, facility name/ID. Map also overlays demographic, income, and health data. This is a Geographic Information System.
- Tox Town: Interactively learn about commonly encountered toxic substances, your health, and the environment by neighborhoods, locations, or chemicals. Tox Town's target audience is students above elementary-school level, educators, and the general public. Tox Town also offers some resources in Spanish.
- ATSDR (Agency for Toxic Substances & Disease Registry) ToxFAQs: View factsheets that provide answers to the most frequently asked questions about hazardous substances found around hazardous waste sites and the effects of exposure on human health.
