The Toxics Release Inventory, or TRI, is a national database maintained by the U.S. Environmental Protection Agency. It contains information about the releases of toxic chemicals by manufacturing industries. The TRI was established under the federal Emergency Planning and Community Right-to-Know Act of 1986. It is sometimes referred to as Title III, Section 313 of the Superfund Amendments and Re-Authorization Act. The purpose of the TRI is to provide local communities information about routine releases of toxic chemicals to the air, land and water, so they can be informed and take action where necessary.

By federal law, annual Toxics Release Inventory, or TRI, reports are to be filed with both the U.S. Environmental Protection Agency and the state environmental agencies.

The Missouri Department of Natural Resources participates in the EPA's Toxics Release Inventory CDX.  Facilities no longer need to provide a paper or CD copy of the Form R.

There are no fees associated with submittal of annual TRI reports to Missouri.

In Missouri, if a facility wishes to provide a paper or CD copy, this filing should be mailed to:
