Chicago O'Hare International Airport (IAP) Air Reserve Station
(ARS) began operations as an aircraft assembly plant and later
housed the Air Force Reserve and the Air National Guard.
Environmental cleanup studies at the installation began in
1983. In 1993, the BRAC Commission recommended closure of
the station. This decision was modified by the 1995 BRAC
round. In late 1996, the Air Force and the City of Chicago
signed a purchase agreement. The city paid for replacement
facilities at Scott Air Force Base, Illinois, in exchange for the
Chicago O'Hare IAP ARS land. Site types identified at the
installation include underground storage tanks (USTs), landfills
(LFs), fuel spills, aboveground storage tanks, a fire training
area, and a low-level radioactive waste disposal area. Primary
contaminants are petroleum hydrocarbons, metals, polynuclear
aromatic hydrocarbons, volatile organic compounds (VOCs),
and semivolatile organic compounds (SVOCs), which have
been released into soil and groundwater. Interim remedial
actions have included removal of 19 USTs, contaminated soil,
and low-level radioactive waste. In FY97, a stationwide
Environmental Baseline Survey (EBS) was completed and in
FY98 parcel-specific EBSs were completed for Parcels 2, 3,
and 3A. The installation formed a Base Closure and Transition
Team and a BRAC cleanup team (BCT).
Environmental cleanup studies have identified 19 Installation
Restoration Program (IRP) sites and 23 areas of concern. To
date, a basewide Record of Decision (ROD) and the LF 1 (LF
001) ROD have been signed, and all property has been
transferred. The cleanup progress at Chicago O'Hare IAP ARS
for FY02 through FY05 is detailed below.
In FY02, the installation submitted the basewide ROD, and
developed a draft institutional control management plan
(ICMP).
In FY03, the basewide ROD and subsequent deed addressed
all areas except for LF 001. The BCT developed a risk
assessment for LF 001 and the installation implemented the
ICMP.
In FY04, Chicago IAP ARS completed a human health risk
assessment and drafted a feasibility study and proposed plan
for LF 001 in preparation for the final ROD. The installation

completed an EBS for the remaining property. The installation
selected a remedy for LF 001. The Air Force conducted an
inventory of Military Munitions Response Program (MMRP)
sites. MMRP sites were identified at this installation.
In FY05, Chicago IAP ARS completed the ROD for LF 001. The
installation also completed the finding of suitability to transfer
for the remaining four acres and transferred the property to the
City of Chicago. The installation attained the last remedy in
place milestone. BCT activities continued. The Air Force began
evaluating requirements at MMRP sites at this installation.
