The Former Nansemond Ordnance Depot (FNOD) consists of
approximately 975 acres on the James River at the mouth of
the Nansemond River. The Army acquired the property
between 1917 and 1929 and used the Depot from World War I
until November 1950 when the property was leased to the
Navy. In 1960, the Army excessed the property and conveyed it
to the Beaszley Foundation, Inc. Currently, Tidewater
Community College (TCC), the General Electric Company
(GE), Dominion Lands, Inc., Continental Bridgeway Office Park,
Bridgeway LP, Suffolk Towers, SYSCO Food Services,
Hampton Roads Sanitation District, Lockheed Martin, and
Interstate 664 occupy the property. Contaminants identified at
the property include TNT, fuels, solvents, pesticides, and
munitions and explosives of concern (MEC). In FY97, FNOD
held its first Restoration Advisory Board (RAB) meeting. EPA
placed the property on the NPL in July 1999 and delisted the
impregnite kit area soils from the NPL in FY03. Both the FNOD
project delivery team and the statewide FUDS Management
Action Plan team meet monthly. In addition, an EPA Region III
FUDS Partnering team meets several times throughout the
year. FNOD also has a highly effective public affairs work group
with representation from regulatory agencies, property owners,
and community stakeholders. Additionally, the FNOD RAB
meets six times a year.
To date, the U.S. Army Corps of Engineers (USACE) has
signed one No Further Action (NFA) Record of Decision (ROD).
Continuous MEC response action presence began in 2000 and
is expected to continue through FY08. The cleanup progress at
FNOD for FY02 through FY05 is detailed below.
In FY02, USACE completed the closeout documentation for the
impregnite kit area and a draft remedial investigation (RI) on the
main burning ground and horseshoe-shaped pond. Work
continued on the TNT area RI, background study, and site
screening process. USACE completed MEC removal actions on
Dominion Lands property, and signed the interim land use
control implementation plan (LUCIP) for MEC at FNOD.
In FY03, EPA delisted the impregnite kit area soils from the
NPL. USACE completed RI sampling of the TNT area and
re-interred the human remains unearthed at the James River
beachfront site with an unprecedented outpouring of community

support. USACE found that the Track K dump had
unanticipated contamination, and was no longer proposed for
NFA. USACE completed the time-critical removal action
(TCRA) at the TNT area and discovered an additional MEC site
at the Nansemond River beachfront. Although there is no
evidence of chemical weapons materiel (CWM) storage or
disposal at FNOD, EPA completed a second round of CWM
sampling citing concerns over incomplete site documentation.
The sampling yielded no indication of CWM.
In FY04, USACE completed the offshore NFA proposed plan
(PP) and ROD. USACE initiated the site investigation phase of
the Nansemond River Beachfront, the Marine Corps Power
Generation Station, and Tracks G, H, and I explosive magazine
lines. Negotiations continued with landowners on the LUCIP
memorandum of agreement (MOA). USACE completed the
initial site screening process for the GE Pond area of concern
(AOC).
In FY05, USACE completed the sitewide groundwater
conceptual site model investigation, a background sampling
report, and FNOD site specific screening process. USACE also
completed near shore site investigations for the James River
beachfront, and Horseshoe Pond, as well as the human health
risk assessment (HHRA) and ecological risk assessment (ERA)
for the Track K dump and the Horseshoe Pond. USACE
determined that an engineering evaluation and cost analysis for
the Pesticide Drum area was inappropriate, and began an
HHRA and ERA as part of an RI. USACE also initiated site
investigations of several AOCs. USACE satisfied the
requirements of the FNOD TCRA interagency agreement and
began drafting the final report. TCC and USACE signed a
LUCIP MOA. USACE also modified its MEC work plan.

USACE signed a final letter of agreement concerning public
information access and interim LUC with the City of Suffolk.
The Corps continued RI work at James River Beachfront,
Horseshoe Pond, Main Burning Ground (MBG), TNT, Pesticide
Drum, and Track K Source Area 6. The district postponed
completion of the James River Beachfront RI to allow
completion of a feasibility study (FS) for shoreline stabilization
and incorporation of the shoreline stabilization FS into the RI to
support an action PP and ROD.
Technical issues delayed the Horseshoe Pond RI. Regulatory
issues delayed the NFA ROD and Pesticide Drum area RI. The
TNT RI is essentially complete and the Draft RI report has been
submitted for review. USACE is awaiting regulatory comments
on the Draft TNT Area RI.
The district held a public meeting for the Track K dump PP.

USACE completed most of the munitions clearance at MBG,
designated two new AOCs (AOC 23-Renovation Plant and
AOC 22-Arsenic Area) on TCC property near the Nansemond
River, and initiated site screening process investigations at
AOCs 12, 14, 15, 20, 22, and 23. EPA completed and accepted
the TCRA report. The installation found bulk TNT at the
Nansemond River Beachfront in July, characterizing this
location as an NPL Source Area.
Technical issues delayed the MBG Military Munitions Response
Program (MMRP) clearance process. The district delayed the
IRP category RI until the MMRP investigations are completed.
