There are numerous entities involved in Hanford Cleanup. The two main agencies who regulate Hanford
cleanup as part of the Tri-Party Agreement, are the Environmental Protection Agency and the Washington
State Department of Ecology.
There are also council and board members who help guide cleanup decisions and post-cleanup outcomes
-- the Hanford Advisory Board and the Hanford Natural Resources Trustees Council.
In addition, the Defense Nuclear Facilities Safety Board provides oversight of Department of Energy work.
Congress created the Defense Nuclear Facilities Safety Board (Board) as an independent
agency within the Executive Branch to identify the nature and consequences of potential threats to public
health and safety at the Department of Energy’s (DOE’s) defense nuclear facilities, to elevate such issues
to the highest levels of authority, and to inform the public.
