The 2005 BRAC Commission recommended Kansas Army
Ammunition Plant (AAP) for closure. The Army established
Kansas AAP in 1941-42 as part of the pre-World War II
build-up. The original construction consisted of three load lines,
four component areas, an ammonium nitrate area, five
explosive storage areas, an inert storage area and a
maintenance and administration area. The RCRA Part B permit,
issued in August 1989, identified 25 solid waste management
units requiring investigation for possible contamination. Areas
of investigation include production areas, landfills, open burning
cages, open burning pads, an open detonation area, and
miscellaneous maintenance and support areas. Primary
contaminants of concern in the production and open burning
areas are explosives and metals. The Army has detected
explosives in groundwater in some production areas. The
greatest hazards in the production areas were generally highest
near the sumps and production facilities. The Army detected
some contamination at all landfill areas. Two closed landfill
areas contained volatile organic compounds (VOCs),
semi-volatile organic compounds (SVOCs), and metals in
surface soils and groundwater. The Phase I RCRA facility
investigations of contaminated sites began in FY92 and were
completed in FY98. The human health risk assessment and
ecological risk assessment were approved in FY99.
The installation completed a corrective measures study (CMS)
that identified some sites for no further action and five sites for
corrective actions. The Army has completed removal actions for
explosives contamination and metals-contaminated soils at the
900 Area, 1000 Area, 1100 Area, and open burn areas. The
cleanup progress at Kansas AAP for FY02 through FY05 is
detailed below.
In FY02, the installation completed the final data gap study for
various contaminants in soil and groundwater at KAAPs 01, 02,
03, 04, 05, 09, 10, 16, 17, 19, 20, 21, 22, 28, and 37.
In FY03, Kansas AAP completed the installation of a monitored
natural attenuation system for the 700 Area Groundwater. The
installation also completed additional investigation of the
groundwater at KAAP 22.

In FY04, the installation completed remedial actions for soil at
KAAPs 10, 20, 21, 22, and 41 using excavation and thermal
treatment of explosives-contaminated soil and
solidification/stabilization of metals-contaminated soil. The
installation also initiated further investigations of KAAPs 17 and
19 groundwater.
In FY05, the BRAC Commission recommended Kansas AAP
for closure. Kansas AAP completed the Closure/Post-Closure
Plan for the 700 Area Groundwater. Kansas AAP also
completed an installationwide CMS for groundwater and landfill
covers, and remedial investigations at KAAP 43.

The installation presented a sitewide Statement of Basis to the
public. The Army initiated an Environmental Condition of
Property report in response to the BRAC 2005 recommendation
for closure of the installation.
