Environmental Response and Revitalization Site Summary

Rickenbacker Air National Guard Base

Rickenbacker Air National Guard Base (Rickenbacker ANGB) is located in Franklin and Pickaway counties in a rural/residential area, 12 miles southeast of downtown Columbus and just east of the Village of Lockbourne. A majority of the property is in Franklin County.

Over the life of the base, it has been known by several names. Construction of the base began in January 1942, and the original name of the base was Northeastern Training Center of the Army Air Corps. For a long period of time, the base was named Lockbourne Air Force Base. In 1974, the base was renamed Rickenbacker Air Force Base in honor of Eddie Rickenbacker. In 1980, the Air Force transferred 4,000 acres to the Ohio Air National Guard and the base was renamed Rickenbacker ANGB.

In 1984, approximately 1,600 acres were transferred to the Rickenbacker Port Authority (this acreage is being addressed under the Formerly Used Defense Sites (FUDS) program administered by the U.S. Army Corps of Engineers). In 1994, as a result of 1991 and 1993 decisions by the Base Relocation and Closure Commission (BRAC), the base was closed.

Operations at Rickenbacker ANGB that have used and disposed of hazardous materials/wastes on-site include: aircraft maintenance, aerospace ground equipment maintenance, liquid fuels maintenance, transportation maintenance, transportation paint shop operations, power production, machine shop operations and flight simulation. Operations involved: corrosion control, nondestructive inspection, fuel cell maintenance, engine maintenance and pneudraulics. The above activities generated waste oils, recovered fuels, spent cleaners, strippers, solvents and other hazardous wastes.

Initially, the Air Force evaluated 27 sites in a preliminary assessment (PA). From this PA, 22 sites moved forward for further evaluation in a site investigation (SI). Free product was found at some locations. Ground water, surface water, soils and sediments were determined to be contaminated with volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), metals, pesticides, total petroleum hydrocarbons (TPH), sulfate and PCBs.

A supplemental environmental baseline survey (SEBS) was conducted on 36 sites. Two of these sites were identified as needing more investigation.

A remedial investigation/feasibility study (RI/FS) was conducted. From this effort, it was determined that five sites required remedial action: three from the PA and two from the SEBS. A remedial action decision document was signed by the BRAC Cleanup Team (BCT) for five sites: Sites 2, 21, 41, 42 and 43. The BCT consists of three members: one each from the U.S. Air Force, U.S. EPA and Ohio EPA.

Sites 2, 21, 41, 42 and 43 began operation and maintenance in 2000 to address ground water contamination caused by VOCs. Hot spot removal and monitored natural attenuation was the remedy selected for Sites 21, 41, 42 and 43. The remedial action for Site 2 included a cut-off trench with a reactive wall. The reactive wall has been decommissioned and the remaining monitoring wells have been abandoned. Sites 2 and 43 have now met their remediation goals. Sites 21, 41 and 42 continue to be monitored. Four sites have been transferred to the Columbus Regional Airport Authority. Site 41 will not be transferred but will be assigned to the Ohio Air National Guard at some time in the future.
