This decision document changes components of the selected interim remedial action for the Hanford 100 Area radioactive liquid effluent disposal sites and clarifies the roles of revegetation or remediated sites with respect to the completion of the remedial actions. This amendment increases the scope of the selected remedy to include 34 additional sites in the 100 Area that received similar waste discharges and reduces the overall estimated cost for the remedial action to $194 million for 71 sites. This amendment also recognizes the results of the soil volume reduction treatability studies that indicate soil washing for volume reduction is not cost effective. Therefore, this treatment step will no longer be retained as an option for the 100 Area radioactive liquid effluent disposal sites. This amendment also clarifies that revegetation of remediated wastes sites will be addressed using the guidance provided in the current Mitigation Action Plan.
