Director's (Final) Determinations

The Tri-Party Agreement (TPA) allows the Director of the Department of Ecology (Ecology) to issue a Determination whenever negotiations to modify the TPA fail to achieve a resolution. The U. S. Department of Energy (DOE) has 30 days to appeal a decision. If DOE does not make an appeal or if an appeal is denied, the determination becomes part of the TPA.
