TRI Connections

Beyond TRI, there are many other EPA programs that collect information about regulated chemicals. The figure below is an overview of key laws that EPA implements with some associated regulated activities or industrial processes.

 

The Toxics Release Inventory (TRI) is a uniquely powerful resource that collects information about how toxic chemicals are managed by certain facilities in the United States. While most EPA programs focus on one environmental medium, the TRI Program covers all environmental media by tracking toxic chemical releases to air, water, and land, as well as chemical waste transfers. TRI also tracks other waste management practices and the implementation of pollution prevention. Since facilities report annually, TRI is one of EPA’s most up-to-date sources of data. The data can be used with other datasets to provide a more complete understanding of national trends in chemical waste management practices.

Throughout EPA, offices use TRI data to support their mission to protect human health and the environment. These uses include technical analysis for regulation, informing program priorities, providing information to stakeholders, and many other applications.
