4. RBES Policy • DOE Policy 455.1 - Use of Risk-Based End States (7/15/03) • RBES are: “representations of site conditions and associated information that reflect the planned future use of the property and are appropriately protective of human health and the environment consistent with that use.” • With RBES, cleanup efforts can be focused so they are both cost effective and protective
