Toxics Release Inventory in Washington State
The Toxics Release Inventory (TRI) identifies chemicals manufactured and used at certain businesses or facilities. It tracks accidental and routine releases of those chemicals to air, land, and water and how waste is managed or disposed.
TRI results help states and communities understand potential risks from chemical releases. The information helps us plan to reduce these risks, improve safety, and protect our environment. TRI is under Section 313 of EPCRA, the Emergency Planning and Community Right-to-Know Act.
Facilities in Washington send TRI reports to both the U.S. Environmental Protection Agency (EPA) and the state. Ecology manages the reports in Washington. EPA compiles the national TRI data each year and makes the information available through several data access tools:
