The Hanford Advisory Board (HAB) develops consensus advice on major policy issues related to Hanford Site cleanup. The advice is provided to the Tri-Party Agreement (TPA) agencies – the U.S. Department of Energy, Environmental Protection Agency and Washington State Department of Ecology. HAB members will listen to committee reports, pause for a 15 minute public comment opportunity at 9:45, and finalize work on a draft white paper about system plan assumptions – the analyses of different ways to complete the retrieval, treatment and disposal of waste stored in underground tanks at the Hanford Site. The meeting will conclude with board business.
