EPA released the 2005 TRI Data on March 22, 2007. This page provides an overview of the 2005 TRI data and relevant TRI information (including analysis, tables, charts, maps, etc). To fully understand the TRI data, we recommend that you read all of the materials.

What is the Toxics Release Inventory (TRI) and what do the data show for 2005?

The Toxics Release Inventory (TRI) is a database containing detailed information on nearly 650 chemicals and chemical categories that over 23,000 industrial and federal facilities manage through disposal or other releases, and waste management for recycling, energy recovery, or treatment.

This inventory was established under the Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA) and expanded by the Pollution Prevention Act of 1990.

For Reporting Year 2005, 23,461 facilities reported to EPA’s TRI Program. These facilities reported 4.34 billion pounds of on-site and off-site disposal or other releases of the almost 650 toxic chemicals.  Over 88 percent of the total was disposed of or otherwise released on-site; almost 12 percent was sent off-site for disposal or other releases. For more information about the TRI program, see the What is the Toxics Release Inventory (TRI) Program fact sheet.

What about facility data errors?

We check facilities' reports for data quality. When we find a potential error, we notify the facility. However, we cannot correct a reporting error in the TRI database until the facility sends us a certified revision or withdrawal. As you use TRI data, be aware that the database may reflect uncorrected facility reporting errors.

What other information should I consider when using TRI data to assess releases in my neighborhood?

Release estimates alone are not sufficient to determine exposure or to calculate potential risks to human health and the environment. TRI data, in conjunction with other information, such as the toxicity of the chemical, the release medium, and site-specific conditions, can be used as a starting point in evaluating exposures that may result from releases of toxic chemicals.
