The Army constructed Joliet Army Ammunition Plant (AAP) in
the early 1940s. It was then one of the largest munitions and
explosives manufacturers in the Midwest. Installation
operations included manufacturing explosives, and loading,
assembling, and packing (LAP) munitions for shipment. EPA
placed the 9,159-acre Manufacturing Area and the 14,385-acre
LAP Area on the NPL in July 1987 and March 1989,
respectively. The installation consolidated all sites into two
operable units (OUs), one for groundwater contamination and
another for contamination of soil. The installation signed an
interagency agreement (IAG) in June 1989. In FY95, the
installation formed a Restoration Advisory Board. In FY04, the
installation completed 5-year reviews for soil and groundwater
OUs.
Environmental studies conducted between FY78 and FY88
identified 53 sites at Joliet AAP. The Army has transferred
nearly 22,000 acres, including 15,000 acres to the U.S. Forest
Service, almost 2,820 acres to the State of Illinois for industrial
park reuse, 2,630 to U.S. Department of Agriculture (USDA),
982 acres to U.S. Department of Veterans Affairs, and 455
acres to Will County, Illinois. The Army also completed an
installationwide Record of Decision (ROD) in FY99. The most
significant cleanup activities completed through FY01 were
excavation and treatment of many thousand tons of
contaminated soil. The cleanup progress at Joliet AAP for
FY02 through FY05 is detailed below.
In FY02, the installation completed bioremediation of 36,000
tons of explosives-contaminated soil. The Army conveyed 455
acres to Will County, Illinois. The Army initiated the ROD for
future USDA lands. The installation initiated an inventory of
closed, transferred, and transferring ranges and sites with
unexploded ordnance (UXO), discarded military munitions, or
munitions constituents that identified Military Munitions
Response Program (MMRP) sites at this installation. Two sites
were cleared of UXO. The Army resumed excavation of
explosives-contaminated soil from the TNT production area and
excavated over 40,000 tons. Prior to the last tenant leaving the
installation, the installation swept their function test area and
removed UXO debris prior to acceptance of the property.

In FY03, the installation excavated an additional 40,000 tons of
explosives-contaminated soil from the TNT production area and
bioremediated 36,000 tons of soil. The Army initiated a site
inspection (SI) at four MMRP sites. A multi-agency group,
which includes the Army, EPA, Illinois EPA, USDA, the U.S.
Forest Service, U.S. Fish and Wildlife Service, and the Illinois
Department of Natural Resources, reached agreement on the
cleanup goals for Joliet AAP lands transferred to USDA.
In FY04, the installation completed 5-year reviews for soil and
groundwater OUs. The Army transferred 305 acres to the State
of Illinois; the remaining balance of land is slated for the Island
City Industrial Park. The installation completed a feasibility
study, proposed plan, and ROD for lands transferred to USDA
and initiated a transfer of 2,440 acres to USDA. The installation
excavated and bioremediated an additional 36,000 tons of
explosives-contaminated soil. Additionally, the installation
initiated the SIs for MMRP sites.
In FY05, Joliet AAP completed remedial action (RA) in the TNT
Area. The Army transferred 304 acres of Deer Run Industrial
Park to the State of Illinois and 2,630 acres to USDA. The Army
began RA for future USDA lands. The Army initiated a
performance-based contract (PBC) for landfills and
groundwater. The installation completed an SI of MMRP sites.
The PBC addressing landfills and groundwater also includes
optional line items to conduct post-SI actions at the four MMRP
sites.
p‰HT2s‚€2€�������
The installation completed cleanup and developed transfer
documentation for 235 acres to the State of Illinois, 20 acres
less than the original estimate. It also completed cleanup and
developed transfer documentation for 580 acres to USDA.
Joliet AAP completed RA at Sites L1, L4, L7, L8, L9, L10, M2,
and M9 and continued the long-term management (LTM)
program for groundwater.
Technical issues delayed the transfer of 145 acres to the
USDA.
p‰HT2ww‚€2€�������
The installation initiated the remedial design for three MMRP
sites and implemented RA for one MMRP site.
