Improve the quality of Washington's natural resources
Indicator 1: Reducing Impacts on the Environment.
Measure c: Toxics Release Inventory (TRI) Releases
Description:
Facilities in Washington that store a certain amount of a hazardous chemical must report annually to the Department of Ecology. Toxic chemical release reporting is tracked through an annual summary, the Toxics Release Inventory (TRI). Over 600 chemical compounds and/or chemical categories are reported under TRI. Reporting requirements may change over time; reporting thresholds may change and industrial sectors may be added. The large increase in land releases in 2004 was due to the opening of the Pend Oreille mine.
