Tri-Party Agreement Milestones
In 1989, the U.S. Department of Energy, the U.S. Environmental Protection Agency, and the State
of Washington, Department of Ecology (hereinafter referred to as the parties) signed a
comprehensive cleanup and compliance agreement for the Hanford Site. The Hanford Federal
Facility Agreement and Consent Order (Tri-Party Agreement) provides an agreed to plan and
schedule for cleaning up the Hanford Site in accordance with the Comprehensive Environmental
Response Compensation and Liability Act (CERCLA), the Resource Conservation and Recovery Act
(RCRA) and the State of Washington Hazardous Waste Management Act (HWMA) regulations.
More specifically, the Tri-Party Agreement
defines and ranks CERCLA and RCRA cleanup commitments, establishes responsibilities, provides a basis for budgeting, and reflects a concerted goal of achieving full regulatory compliance and remediation,
with enforceable milestones.
The Groundwater Remediation Project is guided by several Tri-Party Agreement milestones, which are listed
below.
