This proposed plan address the remediation of tanks at the Oak Ridge Y-12 Plant which contain mercury-contaminated sediment. The contaminated sediment has accumulated in the bottom of the tanks as a result of mercury-contaminated groundwater pumped from the fan-room sumps in the basements of Buildings 9201-4 and 9201-5. Water pumped from these buildings passes through these tanks prior to discharging into Upper East Fork Poplar Creek. As the contaminated water flows through Upper East Fork Poplar Creek and East Fork Poplar Creek in the city of Oak Ridge, the potential exists for absorption of mercury by aquatic organisms. The purpose of this remediation effort is to reduce the risks associated with mercury in surface waters. Three alternatives for remediating the tanks were evaluated using the nine Comprehensive Environmental Response, Compensation, and Liability Act evaluation criteria. These alternatives were (1) take no action, (2) abandon the tanks in place, or (3) remove and dispose of contaminated sediment. Alternative 3 is recommended as the preferred alternative for remediating the tanks. 3 figs., 1 tab.
