11.4.1 QUANTITIES OF TOXICS RELEASE INVENTORY CHEMICALS IN WASTE BY INDUSTRY
The Toxics Release Inventory (TRI) is a publicly available database that contains information on
waste management activities reported annually by certain industries and federal facilities. There are
nearly 650 toxic chemicals and toxic chemical categories on the list of chemicals that must be
reported to EPA and the states. These chemicals do not always correspond exactly to RCRA wastes;
however, they provide a useful overview of the types and amounts of toxic chemicals generated in
the United States.
According to the TRI, the chemical manufacturing industry reported the largest quantity of
toxic chemicals in production-related waste managed in 2001, with 10.69 billion pounds or 40% of
the total reported by all industries (Table 11.6). The primary metals industry reported the second
largest quantity of toxic chemicals in production-related waste managed in 2001, with 3.10 billion
pounds or 12% of the total. The metal mining industry reported the third largest quantities of toxic
chemicals and the largest quantity released on- and off-site in 2001. With 2.87 billion pounds, metal
mining facilities accounted for 11% of toxic chemicals in production-related waste managed by all
