Toxics Release Inventory, Pacific Southwest: National Analysis

The Toxics Release Inventory (TRI), also known as Community Right-to-Know, is a valuable source of information about toxic chemicals that are being used, manufactured, transported or released into the environment. Businesses that are subject to the law must report on their releases to the environment of over 650 toxic chemicals and chemical categories. The public can access this information and find out what pollutants are being released by specific facilities. For more information on TRI, see the national TRI website.

EPA's Region 9 Toxics Release Inventory program helps businesses comply with the regulations and enforces against non-compliant facilities, helps the public access Toxics Release Inventory data, and works with the State Toxics Release Inventory programs of Arizona, California, Hawaii and Nevada.
