The Tri-Party Agreement (TPA) agencies – the U.S. Department of Energy (DOE), the Washington State Department of Ecology (Ecology), and the U.S. Environmental Protection Agency (EPA) – hold meetings throughout the Pacific Northwest to provide a forum for the public to discuss Hanford cleanup progress, challenges and priorities with decision-makers from the TPA agencies.  The meetings feature an open house with displays and information from the TPA agencies as well as regional organizations involved or interested in Hanford cleanup.
