Stage of Clean-up: Construction Underway
Conditions at proposal (April 10, 1985): Tinker Air Force Base covers 4,277 acres adjacent to Oklahoma City, Oklahoma County, Oklahoma. The base is within the North Canadian River drainage basin and drains into Crutcho and Soldier Creeks. It overlies the Garber-Wellington Formation. This NPL site is bounded by 59th Street, Douglas Boulevard, Building 3001, and the base boundary to the north. Building 3001 is used for aircraft maintenance and jet engine rebuilding. Organic solvents, including TRICHLOROETHYLENE (TCE), TETRACHLOROETHYLENE, and l,2-dichloroethylene, were used for degreasing and aircraft maintenance. In the past, waste oils, solvents, paint sludges, and plating waste generated from maintenance activities were disposed in Industrial Waste Pits Numbers l and 2, located about l mile south of Soldier Creek and Building 300l. Current waste is disposed off-site at landfills permitted under the Resource Conservation and Recovery Act (RCRA) or the State. The base acquired Interim Status under RCRA Subtitle C when it filed an application for a permit to store hazardous wastes. Tests conducted by a contractor to the Air Force detected TCE in a water supply well located within Building 3001. The Air Force has taken this well out of service. More...
