The report represents the second annual publication of the Toxics Release Inventory (TRI) collected pursuant to the Emergency Planning and Community Right-to-Know Act of 1986. TRI is an annual, publicly available compilation of information on the release of toxic chemicals by manufacturing facilities in the U.S. The report summarizes the second year of TRI data--where, how much, and which types of toxic chemicals are being released into the environment--and provides comparisons to the first year's releases. The document is intended as a tool for improving environmental management. By emphasizing pollution prevention--finding ways to eliminate the formation of toxic pollutants--we can improve protection of the environment, reduce risk to health and avoid much of the expense of managing or treating wastes.
