Risk-Based Corrective Action Plan Hazardous Waste Storage Area (Building 560), Richenbacker Air National Guard Base, Columbus, Ohio. Volume 1. Report and Appendices

摘要

This risk-based corrective action plan includes conservative estimates of risk, conclusions, and recommended corrective actions for the former hazardous waste storage area (HWSA) at Building 560, Rickenbacker Air National Guard Base (ANGB), Ohio. The former HWSA is located at the edge of the shop area in the northern section of the Base. The HWSA was a permitted Resource Conservation and Recovery Act (RCRA) storage facility that received wastes generated during Base activities from 1983 through 1986. Wastes stored at the HWSA consisted primarily of acids, various solvents and cleaning solutions, petroleum products, and spent desiccants. Waste was stored in small containers placed on pallets inside Building 560 and in larger, 55-gallon drums outside the building (within the fenced yard). Additionally, 15 underground storage tanks (USTs) were previously located at or near the HWSA. These USTs were used for the storage of fuel waste, waste petroleum products, and deicing fluid. The Air Force Base Conversion Agency (AFBCA) has been granted No Further Response Action Planned (NFRAP) status for the tanks. Residual contamination in soil and groundwater is addressed as part of the risk-based corrective action presented in this report.
