Toxics Release Inventory Summary of requirements  The database
is available from the United States Environmental Protection
Agency (EPA) and contains information reported annually by some
industry groups as well as federal facilities. Each year,
companies across a wide range of industries (including chemical,
mining, paper, oil and gas industries) that produce more than
25,000 pounds or handle more than 10,000 pounds of a listed
toxic chemical must report it to the TRI. The TRI threshold was
initially set at 75,000 pounds annually. If the company treats,
recycles, disposes, or releases more than 500 pounds of that
chemical into the environment (as opposed to just handling it),
then they must provide a detailed inventory of that chemical's

Congress established TRI under the Emergency Planning and
Community Right-to-Know Act of
