In July 1991, the BRAC Commission recommended closure of
Rickenbacker Air National Guard (ANG) Base, which had
supported aircraft operations. In July 1993, realignment was
recommended rather than base closure. The installation was
realigned on September 30, 1994. Rickenbacker ANG Base
was proposed for listing on the NPL in January 1994, because
of the potential effects of contamination on underlying
groundwater. A Restoration Advisory Board formed and a
basewide Environmental Baseline Survey was completed in
FY94. In FY95, a final environmental impact statement was
published. From FY96 through FY97, a supplemental remedial
investigation report was completed. Remedial actions (RAs)
included removal of 59 underground storage tanks, 28
aboveground storage tanks, and asbestos-containing materials;
closure of abandoned fuel lines; and demolition of the heat and
water plant lagoons. In FY06, the installation finalized the first
5-year review.
To date, all Records of Decision have been signed. The Air
Force has transferred approximately 1,739 acres to the local
redevelopment authority (LRA). No further remedial action
planned documents were signed for 16 Installation Restoration
Program (IRP) sites and 3 areas of concern. Seven other IRP
sites were closed with regulatory concurrence. The cleanup
progress at Rickenbacker ANG Base for FY02 through FY05 is
detailed below.
In FY02, the amended Site 1 closure and post closure plan was
approved. The draft land use control/institutional control
(LUC/IC) layering strategy plan was updated and submitted to
regulators for comment.
In FY03, the installation transferred 310 acres to the LRA and
published the final investigation report for Site 12/597.
In FY04, the installation completed the 2-year report for IRP
Sites 2, 21, 41, 42, and 43, and finalized the LUC/IC
management plan. After review of groundwater data, the
basewide groundwater restriction was removed. The installation
shut down the groundwater treatment system at Site 2 and
initiated monitored natural attenuation. The two
vacuum-enhanced recovery systems at Pumphouses 898/899
and Segment G of the 1942 fuel line were turned off. A

remedial process optimization (RPO) study was completed. The
first 5-year review was initiated. The Air Force Real Property
Agency (AFRPA) conducted an inventory of Military Munitions
Response Program (MMRP) sites. No MMRP sites were
identified on the BRAC portion of the installation.
In FY05, the installation obtained approval letters for operating
properly and successfully (OP&S) demonstrations at IRP Sites
21 and 42. A Statement of Basis for No Further Action was
signed for Site 43 contingent upon the land use requirements.
The installation transferred 47 acres of Parcel D3A and 15
acres of Parcel D3B containing the petroleum/oil/lubricant bulk
storage area to the LRA. The installation continued to work on
the draft 5-year review. The Air Force awarded a
performance-based contract to close the remaining IRP Sites,
Sites 1, 2, 21, and 42. The installation also implemented the
RPO recommendations identified during the FY04 study. The
BRAC cleanup team (BCT) reviewed the draft 5-year review
and held one meeting.

The Air Force implemented site closure acceleration
enhancements at Sites 41 and 42; approximately 100 cubic
yards of contaminated soil were removed from Site 41. The
installation added an aqueous solution of food grade vegetable
oil and simple sugars to the groundwater to act as a long-term
electron donor and to accelerate site closure at Sites 41 and
42. The installation expanded the air sparge system at Site 2.
Rickenbacker ANG Base finalized the first 5-year review. The
installation submitted the Site 2 demonstration of an RA OP&S
document to EPA Region 5 and received approval.
Rickenbacker ANG Base completed transfer of Site 43 (Parcels
B1/D3E and Parcels D3B, D3C, D3F, D3G, and D3K) to the
LRA. The Air Force decided to retain Parcels D3I, D3J, and
D3L for use by the Ohio ANG.
Ongoing discussions about the pilot study at Site 42 delayed
the transfer of Parcel D3D.
The BCT met twice.
