In addition to the above on-line databases, Ecology distributes several databases for local installation and use.

	Toxics Release Inventory Display System (TRIDS) A database that identifies facilities, chemicals manufactured and used, the annual amounts of these chemicals released (in routine operations and in accidents and other one-time events) and otherwise managed on- and off-site in waste.
	Water Quality Permit Life Cycle System (WPLCS) Information on water quality permits for municipalities, industries, dairies, fish-rearing facilities, stormwater, sand and gravel operations, and aquatic pesticides.
