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.
