2007 TRI Public Data Release

EPA released the 2007 TRI Data on March 19th, 2009. This Web page provides an overview of the 2007 TRI data and relevant TRI information (including analyses, 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 2007?

The Toxics Release Inventory (TRI) is a database containing detailed information on nearly 650 chemicals and chemical categories that approximately 22,000 industrial and federal facilities manage through disposal or other releases, or 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 2007, 21,996 facilities, including federal facilities, reported to the TRI Program. They reported 4.1 billion pounds of on-site and off-site disposal or other releases of the almost 650 toxic chemicals, as shown in Table 1. Almost 87% of the total was disposed of or otherwise released on-site; 13% was sent off-site for disposal. Metal mining facilities reported 28% and electric utilities reported 25% of the total in 2007, in the 2007 PDR Brochure.

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. In addition, as TRI incorporates revisions sent in by facilities, data for prior years may change. The 2007 TRI Public Data Release includes updated, revised databases for all prior years so that prior year information may differ from data accessed previously.

Anything else new this year?

EPA is making it easier to access data from facilities about their source reduction, recycling and pollution control activities. Download data (Excel) -2.8MB.

The data was voluntarily submitted by facilities though TRI-ME in Section 8.11 on Form R in addition to other required data entries regarding source reduction, recycling and pollution control activities as provided in the Pollution Prevention Act. This additional optional information describes activities implemented during the reporting year, as well as in prior years. EPA did not review the data to verify or evaluate the activities.

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 (e.g., air), and site-specific conditions, can be used as a starting point in evaluating exposures that may result from releases of toxic chemicals.
