The Environmental Quality Division obtains Toxic Release Inventory (TRI) data for Duval County from the United States Environmental Protection Agency (EPA) on an annual basis. The TRI is a database, which provides information to the public about releases of toxic chemicals at a wide variety of sources, including manufacturing operations, certain service industry businesses and federal facilities.  The TRI was established under the Emergency Planning and Community Right-to-Know Act of 1986 and expanded under the Pollution Prevention Act of 1990. The program has grown over the years to include additional types of industry and additional chemicals.  Facilities are required to report their TRI information annually to the EPA.

A facility must report to TRI if it conducts manufacturing operations within Standard Industrial Classification (SIC) codes 20 through 39, conducts metal mining (SIC 10), coal mining (SIC 12) or is an electric utility that combusts coal and/or oil (SIC 4911, 4931 & 4939).  Also all Resource Conservation and Recovery Act (RCRA) Subtitle C hazardous waste treatment and disposal facilities (SIC 4953) are required to report.  Other facilities which must report include:  chemical wholesalers (SIC 5169), petroleum terminals and bulk stations (SIC 5171), solvent recovery services (SIC 7389),  all federal facilities and all facilities that employ ten or more full-time employees and manufacture or process more than 25,000 pounds or use more than 10,000 pounds of any listed chemical during the calendar year.

The table below includes Duval County TRI air emission data for the years 2000 thru 2002.  For additional Tri data, go to the EPA TRI website at www.epa.gov/tri.
