1. TITLE: 1992 Toxics Release Inventory - Geographic Information System Coverage Files, 1992 Data only
  2. IDENTIFICATION NUMBER: NA
  3. ABSTRACT: Data extracted from the EPA Toxics Release Inventory (TRI) system for reporting year 1992 are written in Arc/INFO geographic information system (GIS) export file format (an ASCII data exchange format). The data are also summarized in tables out of the TRI public data release publication (EPA 745-R-94-001), and are written in Lotus spreadsheet format. The files contain TRI data organized by state which include: facility identification, facility location coordinates which have been reviewed and expanded to identify "preferred" geographic coordinates, year-by-year releases and transfers by medium, quantities in waste, and methods used to identify source reduction activity. When imported to a GIS, the combined set of coverage attributes, facility information, and tabular data for 1992 totals up to forty-seven files per state. Please refer to the file listing and coverage documentation file for more information.

    4. PURPOSE: The United States Toxics release Inventory (TRI) is mandated by Section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA) of 1986. The law is based on the premise that citizens have a right to know about potentially harmful chemicals in their communities. It has two main purposes: to provide planning for response to chemical accidents; and to provide the public and the government with information about possible chemical hazards.

    Under section 313 of EPCRA, certain manufacturers must report on an annual basis the amounts of over 300 toxic chemicals, including those in 20 chemical categories, which are released directly to the air, water or land, or which are injected underground. The reports also include information on amounts transferred to off-site locations for treatment or disposal. The law further specifies that the EPA must compile these reports into an annual inventory that is "publicly available by computer telecommunications and other means" on a cost-reimbursable basis.

    In 1991, facilities also began to provide additional information mandated by the Pollution Prevention Act (PPA) of 1990, such as amounts of chemicals recycled on- and off-site, amounts treated on-site, and amounts released due to non-production related events (e.g. accidental spills). The reports are sent to the U.S. Environmental Protection Agency (EPA) and to the states or tribes.
