Toxics Release Inventory: 2006 Data Release
On this page
EPA's Toxics Release Inventory (TRI) program has released the 2006 data on toxics that are being released to the nation's air, water and land from major industry sectors throughout the United States. These industry sectors include manufacturing industries, which have been reporting their releases since 1987; federal facilities, which started reporting in 1994; and seven additional industry sectors, which began reporting their toxic releases in 1998: metal and coal mining, electricity generation, commercial hazardous waste treatment, solvent recovery, petroleum bulk terminals, and wholesale chemical distributors.
In 2000, the TRI was expanded to include additional persistent, bioaccumulative and toxic (PBT) chemicals, and required reporting for these chemicals at lower thresholds. PBT pollutants are toxic, persist in the environment and bioaccumulate in food chains, posing risks to human health and ecosystems. In 2001, lead and lead compounds were reported as PBT chemicals for the first time. For information on the PBT rule and the lead rule, including a list of chemicals covered, and links to other PBT Web sites, please refer to the National Toxics Release Inventory PBT Web page.
2006 Data Release Information
- 2006 National Data Release
The annual TRI Public Data Release includes a general overview of the 2005 TRI data, information on trends, electronic state fact sheets that provide a brief summary of the TRI data by State, and downloadable data files that contain detailed release information. - Users can access TRI information on toxic chemical releases and other waste management from particular facilities, in particular communities, and by individual chemical through the TRI Web site. The TRI Web site provides links to TRI data access tools, including the TRI Explorer or Toxic Release Query Form, from EPA's data warehouse, Envirofacts.

In comparing 2001 data to previous years, note that the calculation method of sulfuric acid releases from electricity generating facilities has changed
