Toxic Release Inventory (TRI)


The Toxics Release Inventory (TRI) is a resource for learning about toxic chemical releases and pollution prevention activities reported by industrial and federal facilities. CDPHE does not manage TRI data or reporting. All TRI reporting must be submitted electronically through the Environmental Protection Agency (EPA) using TRI-MEweb. The TRI Report is due annually by July 1.
