TRI is an annually compiled series of databases that constitute the toxic releases files on the National Library of Medicine's (NLM) Toxicology Data Network (TOXNET). This series, 1995-1997 reporting years, contains information on the annual estimated releases of toxic chemicals to the environment and is based upon data collected by the Environmental Protection Agency (EPA). Mandated by the Superfund legislation, TRI's data covers air, water, land, and underground injection releases, as well as transfers to waste sites, and waste treatment methods and efficiency, as reported by industrial facilities around the United States. TRI also includes data related to source reduction and recycling.

On September 22, 1992, the Secretary of Energy directed the Department to participate in the Environmental Protection Agency's (EPA) 33/50 Pollution Prevention Program and to initiate Toxic Chemical Release Inventory (TRI) reporting, pursuant to Section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA), at Department of Energy (DOE) sites. The Office of Environmental Guidance, RCRA/CERCLA Division (EH-231) issued interim guidance on March 4, 1993, entitled ''Toxic Chemical Release Inventory and 33/50 Pollution Prevention Program'' that provided instructions on implementing the Secretarial directive. As stated in the interim guidance, all DOE sites not currently reporting under EPCRA Section 313, which meet the criteria for DOE TRI reporting, will initiate reporting of all TRI chemical releases and transfers for the 1993 calendar year with the annual report due to EPA, States and a courtesy copy to EH-20 by July 1, 1994. All other DOE sites which currently report under EPCRA Section 313 will also follow the criteria for DOE TRI reporting.

Contains forms and instructions for the Form R and Form A that TRI (Toxics Release Inventory) submitters use each year to report toxic chemicals released into the land, water, or air.
