In May 2005, the BRAC Commission recommended closure of
the Newport Chemical Depot (CD) after completion of the
chemical demilitarization mission. The installation began to
neutralize VX agent on May 5, 2005. The Wabash River
Ordnance Works (Site 001) originally manufactured the
explosive RDX during World War II and the Korean Conflict. In
addition, heavy water was produced in support of the
Manhattan Project and Atomic Energy Commission. In 1961,
the heavy water production facility was converted to the
production of chemical agent VX and operated until 1969 (Sites
014 and 016). The installation buried building debris at Sites
022 and 025, including asbestos-contaminated and
decontaminated debris from the chemical plant. From 1973 to
1974, the Army constructed a TNT production plant. The
installation burned and buried TNT removed from the
production lines at Site 024. In 2000, Newport CD formed a
Restoration Advisory Board (RAB).
Environmental studies identified 17 sites. Eleven of these sites
have achieved response complete. The cleanup progress at
Newport CD for FY02 through FY05 is detailed below.
In FY02, the installation composted approximately 7,000 cubic
yards of TNT- and DNT-contaminated soils at Site 024. The
installation also treated water that accumulated in excavations
with an activated carbon treatment unit. The Army conducted a
preliminary assessment of the installation's one Military
Munitions Response Program (MMRP) site at Site 022.
In FY03, the installation composted and backfilled
approximately 6,700 cubic yards of RDX-contaminated soils in
excavations at Site 001.
In FY04, Newport CD constructed a soil barrier on a portion of
Site 022. Newport CD also established an inspection program
to periodically check the integrity of the soil barrier and
complete any needed repairs. The Army conducted a
geophysical study to identify the location of a buried 300-gallon
tank at Site 022. The installation also installed a 2-foot-thick soil
cap and 6-inch-thick topsoil layer, and revegetated the area to
control soil erosion at Site 025. The installation established an
inspection program to periodically check the integrity of the cap,

assess the stability of the creek bank, and conduct any needed
repairs.
In FY05, the BRAC Commission recommended closure of
Newport CD. The installation conducted long-term management
(LTM) for groundwater at Sites 001, 022, 024, and 025.
Newport CD completed a land use control implementation plan.
p‰HT2s‚€2€�������
The installation conducted LTM for groundwater at Sites 001,
022, 024, and 025. The installation also conducted cap
inspection at Sites 022 and 025.
Newport CD hosted a RAB meeting.
p‰HT2ww‚€2€�������
The installation initiated a historical records review (HRR) to
identify potential munitions, including landmines, aerial rockets,
secondary explosives, and toxic chemical agents/munitions.
Additional sites identified in the HRR will be addressed in the
environmental condition of property (ECP) report.
