8. 8 Toxics Release Inventory (TRI) Data on toxic chemical releases and waste management activities Reported annually by certain industries Also reported by Federal facilities Provides communities with information to support decision making

13. 13 Other Uses of TRI Data  Financial Sector Used by some mutual funds for “social responsibility”  Labor Unions Used in contract negotiations  Internal Revenue Used for tax on CFCs  Internal Processing Reactions to filing lead to lower releases

14. 14 TRI Data: Beware TRI is not everything –Mobile Sources are not included –Smaller facilities are not included –Toxic Substances Control Act lists 76,000 chemicals –TRI includes 650 chemicals

15. 15 TRI Data: Beware Releases are in pounds Dioxins are measured in grams Releases are NOT health waited

16. 16 TRI Data: Beware The data base changes –TRI started in 1988 –In 1998, metal mining was added (and releases more than doubled) –Just publishing the data encourages reductions in the releases –Out of 650 chemicals, 332 are core chemicals
