The Toxics Release Inventory (TRI) is a publicly available database from the EPA that contains information on toxicchemical releases and other waste management activities reported annually by certain covered industry groups as well as federal facilities. This inventory was first proposed in a 1985 New York Times op-ed piece written by David Sarokin and Warren Muir, researchers for an environmental group, INFORM. TRI was established under the Emergency Planning and Community Right-to-Know Act of 1986 (EPCRA), and later expanded by the Pollution Prevention Act of 1990. The law grew out of concern surrounding Union Carbide's releases of toxic gases in the 1984Bhopal disaster and a smaller 1985 release in Institute, West Virginia See more at Wikipedia.org...
