TRI Toolbox
The Toxics Release Inventory (TRI) Program tracks the industrial management of toxic chemicals. TRI data are reported annually by industrial and federal facilities that meet reporting requirements. EPA makes these data available through multiple online tools, many of which add context to help make the reported data more understandable.
