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.

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.

3745-100-12, Fee System of the Ohio Administrative Code remains in effect regardless of whether a facility submits by the federal Central Data Exchange (CDX) system or in hard-copy format directly to Ohio EPA. The fees are used to implement, administer and continue operations of the Ohio TRI Program. The Fee Calculation Worksheet (Word Document or PDF) must be completed by each facility submitting TRI reports.
