Toxics Release Inventory (TRI) Program

TRI Resources for Communities

EPA and other organizations have developed a variety of materials that can help communities understand and use the Toxics Release Inventory. Some of the items in this list are from 2000 and earlier, and have been included because they still contain useful information. Click on an item in the list to get details about it.
