Toxic Release Inventory (TRI)

The Toxic Release Inventory (TRI) is a database that contains information concerning specific toxic chemical releases, transfers, waste management and pollution prevention activities from manufacturing facilities throughout the United States. This inventory was established under the Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA), which Congress passed to promote planning for chemical emergencies and to provide information to the public about presence and release of toxic and hazardous chemicals in their communities. TRI does not regulate chemical discharges. In Ohio, state authority has been granted to Ohio EPA under the Ohio Right-to-Know Act of 1988 and Ohio Revised Code.

What's New


As part of the 2018-2019 biennium budget, the TRI fees have been totally eliminated. Ohio EPA’s Division of Air Pollution Control will continue to administer the TRI Program and provide technical assistance to the regulated community and the public.

U.S. EPA continues to administer the national reporting program, by providing web-based reporting, web-based training, and user-friendly web-based access to the TRI data.

Ohio EPA Accepts TRI Reports through the Central Data Exchange

Facilities located in Ohio can now submit their TRI information to both U.S. EPA and the Ohio EPA/Toxic Release Inventory Program simultaneously through the Federal Central Data Exchange (CDX) using the TRI-MEweb application. CDX will automatically forward your data to Ohio. This method eliminates the need to generate a diskette or CD to mail separately to Ohio EPA.

The CDX Help Desk can be contacted at 1-888-890-1995, email at or their website at If you wish to register as a CDX user, please click here.
