Superfund Record of Decision (EPA Region 4): Oak Ridge Reservation (USDOE) (sludge removal from the Gunite and Associated Tanks Operable Unit, Waste Area Grouping 1), Oak Ridge, TN, September 2, 1997

Technical Report ·
OSTI ID:638519
This record of decision (ROD) presents the selected interim remedial action for removing mixed transuranic (TRU) waste sludge from eight tanks in the Gunite and Associated Tanks (GAAT) Operable Unit (OU). The tanks are located in Oak Ridge National Laboratory (ORNL) Waste Area Grouping (WAG) 1. The selected interim remedial includes removal of the sludge and subsequent transfer to the Melton Valley Storage Tanks (MVST). The plans for removing GAAT sludge will be included in the remedial design and remedial action documentation. The selected remedy was developed considering the TRU waste strategy (i.e., consolidate, treat, and ship waste to the Waste Isolation Pilot Plant (WIPP) or the Nevada Test Site (NTS)) and the strategy to evaluate residual contamination in the OU after waste removal as part of the Bethel Valley Watershed remediation. After removal of sludge, samples of the tank shell will be collected to provide contaminant levels for consideration during future closure evaluations, as part of the Bethel Valley Watershed remediation.
