This document represents the Corrective Action Plan for underground storage tank 2331-U, previously located at Building 9201-1, Oak Ridge Y-12 Plant, Oak Ridge, Tennessee. Tank 2331-U, was removed on December 14, 1988. Based on the determination that groundwater at the Building 9201-1 Site is classified as a nondrinking water source, the applicable TDEC Closure Action Levels for remediation of petroleum contaminated groundwater at the facility are 0.070 ppm for benzene and 1.0 ppm for total petroleum hydrocarbons. Analytical results for groundwater samples collected during investigations at the Building 9201-1 Site suggest that an area of groundwater contamination exceeding applicable action levels, and measuring approximately 1,500 ft{sup 2}, extends from the Building 9201-1 former tank pit east/southeast toward Building 9105. A wide variety of corrective action responses and options were evaluated for possible remediation of petroleum contaminated soils and groundwater at the Building 9201-1 Site. The recommended corrective action approach for groundwater involves extraction of contaminated groundwater through recovery wells, treatment using aeration, and release of treated groundwater into the Y-12 Plant storm sewer system. If aeration is found to be inadequate, then in-line carbon filtration of the groundwater will be implemented. Based on screening criteria established for the evaluation process, a combination of corrective action options was selected to accomplish soil remediation at the facility. The recommended corrective action approach for soils at the Building 9201-1 Site involves initial excavation and confirmatory sampling of contaminated soils from impact areas, land aeration of these soils at a suitable treatment bed, and final disposal of the treated soils in place at the treatment bed site. If land aeration is found to be unsuccessful in completing remediation of the contaminated soils, then bioremediation will be implemented at the treatment bed.
