From 1941 to 1946, West Virginia Ordnance Works
manufactured TNT from toluene, nitric acid, and sulfuric acid.
By-products of the manufacturing process included TNT,
dinitrotoluene, and organic compounds, which were released
into groundwater, soil, surface water, and sediment. Principal
sites include TNT manufacturing areas, wastewater sewer
lines, and wastewater ponds known as the "red and yellow
water ponds." EPA placed West Virginia Ordnance Works on
the NPL in September 1983. The Army and EPA signed the first
interagency agreement (IAG) in September 1987 and signed a
second IAG in July 1989. The U.S. Army Corps of Engineers
(USACE) converted the technical review committee to a
Restoration Advisory Board in FY98. USACE completed 5-year
reviews in FY95, FY00, and FY05. EPA partially delisted a
509-acre parcel from the NPL in FY03 and an additional 1,004
acres in FY04.
The property is now divided into Operable Units (OUs) 1
through 5 and 7 through 13. To date, the Army and EPA have
signed Records of Decision (RODs) for OUs 1, 2, and 11 and
No Further Action (NFA) RODs for OUs 10 and 12. The former
OU 6 was changed to Environmental Unit 06 and is complete.
OU 7 is a potentially responsible party project with EPA Lead
and OU 13 is under EPA Lead with NFA planned for the Army.
The cleanup progress at West Virginia Ordnance Works for
FY02 through FY05 is detailed below.
In FY02, USACE completed the corrective action at the OU 1
burning grounds. It also completed an interim feasibility study
(FS) for OU 8 (soils) and OU 9 (groundwater) in the TNT
manufacturing area. EPA and USACE signed a NFA ROD for
OU 12. USACE continued long-term management (LTM) and
completed LTM on the OU 11 property. The supplemental
sampling at Ecological Site Inventory (ESI) 6 was completed.
EPA, West Virginia Department of Environmental Protection,
the EPA Biological and Technical Assistance Group, and
USACE personnel and contractors implemented a consensus
agreement approach. This formal facilitated partnering process
enhanced the decision-making ability of the team and resulted
in both time and cost savings.
In FY03, USACE signed NFA decision documents for ESIs 1, 4,
and 6. USACE completed the removal action at Area of
FUDS

Concern (AOC) 18 and initiated the removal action at OU 5.
During the removal action at AOC 18, the team used an
innovative method of stabilization prior to disposal that allowed
a cost savings. Another cost savings resulted from the disposal
of wastewater from the composting operation by using the OU 4
treatment system. USACE signed a NFA ROD for OU 10. The
team completed a comprehensive review of the property and
continued operation of the groundwater extraction and
treatment systems. EPA partially delisted a 509-acre parcel and
USACE prepared a draft notice of intent for partial delisting of
an additional 1,004 acres. The Army conducted an inventory of
closed, transferred and transferring ranges and sites with
unexploded ordnance, discarded military munitions or munitions
constituents at this property, and identified no Military Munitions
Response Program (MMRP) sites.
In FY04, USACE completed the removal of contaminated soils
from OU 5. In addition, the property completed the second NPL
partial delisting of 1,004 acres, bringing the size of the NPL
boundary down to 1,184 acres. USACE also completed the
draft third 5-year review report and a remedial system
evaluation on the groundwater extraction and treatment
facilities to address optimization of the system. USACE initiated
a treatability study (TS) for in situ treatment of groundwater for
OU 9 that uses an innovative hydrogen release compound
injection to clean up the groundwater.
In FY05, the Army completed the third 5-year review report on
schedule. USACE also completed the TS for OU 9.
p‰HT2s‚€2€�������
USACE completed the draft FS and proposed plans (PPs) for
OUs 8 and 9. USACE also received regulatory concurrence on
the OU 4 revised evaluation report.
The property transfer for OU 11 was delayed due to a change
in transfer responsibility. Regulatory and technical issues
delayed the final FSs and PPs for OUs 8 and 9.
p‰HT2ww‚€2€�������
USACE has identified no MMRP sites at this property.
