Description

The Toxics Release Inventory (TRI) consists of information about on- and off-site releases of chemicals and other waste management activities reported annually by industries, including federal facilities.The data includes information on reporting facility, toxic chemical identity, waste treatment and recycling activities.

The fields identify facilities, chemicals manufactured, processed, recycled and disposed of. The location fields give facility sites and which release activities are used in communities. Facilities and sites can be mapped using the fields MAPLONG and MAPLAT. The data shows what happens to the chemical when it leaves the facility, such as whether it is recycled, treated or released into the environment, and where the chemicals are sent. There is also information on one-time accidental releases.

Industries included are manufacturing, metal mining, coal mining, coal and oil burning electrical utilities, hazardous waste treatment and disposal facilities, chemical distributors, petroleum bulk plants terminals, and solvent recycling operations. There are now about 650 toxic chemicals and toxic chemical categories on the list of chemicals that were required to be reported.

Although you can download this data for free off the EPA’s Web site, NICAR data analysts have done a significant amount of cleaning to make this data easier to use immediately. Fields containing standard date formats, mappable latitude and longitude have been added, and the unique id field, TRIFID, has been altered to make it compatable with past years.

  • Report Lists State’s Toxic – Waste Figures
    According to the Toxic – Release Inventory, Ohio is the fifth most polluted state in America. Toxic pollution levels actually went up in some counties from 1989 to 1990. In some cases, residents say the pollution is so bad they sometimes don’t leave their houses. Other residents blame the pollution for the higher rate of respiratory problems and illness in their children. But in Marysville, where the pollution is at its worst, people don’t often complain about it. The reporters speculate that this is because the pollution is caused by Honda of America, which brought thousands of jobs to central Ohio in the early 1980s.
  • Toxic Pollution From Maryland Manufacturers
    This package of five stories examined five years of the most recent data available from the Environmental Protection Agency to determine if toxic pollution released by Maryland manufacturers has declined in recent years; it has, by about 43 percent. The computer-assisted analysis of the Toxic Release Inventory also revealed that Maryland’s biggest polluter was Westvaco, a paper manufacturer based in Allegany County. The series also pinpointed Baltimore and its surrounding counties as the region with the most industrial pollution in Maryland.
  • What’s buried at Hercules?
    This investigation of a Hercules Inc. chemical plant showed a history of questionable environmental practices extending back decades, including the burial of drums of chemicals in the company’s landfill, an EPA report noting more than 37 acres of contaminated soil, and a host of complaints from residents who feared their health had been compromised from the smoke and chemicals. Company officials say there is no evidence toxic chemicals pose a health threat and any contamination is confined to the plant’s site.
