From page 5...
... The addition of large volumes of water to a tank that is expected to leak or is known to have leaked will require prior isolation of the tank using subsurface barriers. If the technology already exists to isolate the tank and prevent migration of waste materials under the extreme conditions of hydraulic sluicing, the same technique should be able to prevent contaminant migration in the absence of hydraulic sluicing.

From page 6...
... 6 CONTAINMENT-IN-PLACE This reexamination should be conducted on a tank-by-tank basis, as well as a tank farm-by-tank farm basis. If containment technologies are capable of isolating the tanks, then waste removal might only be necessary for those special circumstances where the tanks contain materials that are particularly hazardous-for example, where there is the potential for an explosion, where there are excessive temperatures, or where there are large inventories of long-lived radionuclides.
