What is the TRI Explorer?

The TRI Explorer provides access to the Toxics Release Inventory (TRI) data to help communities identify facilities and chemical disposal or other release patterns that warrant further study and analysis. Combined with hazard and exposure information, the TRI Explorer can be a valuable tool for risk identification.

Reporting Year (RY) 2006 is the most recent TRI data available. The TRI 2006 Data Release page provides an overview of the TRI information. Facilities reporting to TRI were required to submit RY 2006 data to EPA by July 1, 2007. TRI Explorer provides access to TRI data frozen as of October 12, 2007.

For more information on generating TRI Explorer reports, see the TRI Explorer Background page. For more information on the TRI program see https://www.epa.gov/tri/whatis.htm. Throughout the year, EPA receives revisions and withdrawals submitted by facilities.To view the most recent data that has been submitted since October 12, 2007, please access EPA Envirofacts.

What are the limitations of TRI Data?

TRI data do have certain limitations. TRI data reflect disposal or other releases and other waste management of chemicals, and not exposures of the public to those chemicals. TRI data alone are not sufficient to determine exposure or to calculate potential adverse effects on human health and the environment. TRI data, in conjunction with other information, can be used as a starting point in evaluating exposures that may result from disposal or other release and other waste management activities which involve toxic chemicals.
