New London Naval Submarine Base maintains and repairs
submarines. Significant sites at the installation include the Area
A landfill (Site 2), a number of smaller disposal areas, and fuel
and chemical storage areas. The Navy placed the installation
on the NPL in August 1990 because of polychlorinated biphenyl
(PCB) contamination at Site 2. In 2005, the BRAC Commission
recommended New London Naval Submarine Base for
realignment. The installation formed a technical review
committee in FY89 and converted it to a Restoration Advisory
Board in FY94. The installation signed a federal facility
agreement (FFA) in January 1995. In FY01, the installation
completed a 5-year review.
Twenty-nine sites have been identified at this installation,
including 22 CERCLA sites, along with underground storage
tanks (USTs) which were grouped into 2 UST sites. The
installation has completed Record of Decision (ROD)
documents for Sites 2, 3, 6, 8, 20, and the basewide
groundwater operable unit (OU). In addition, the installation has
signed No Further Action (NFA) RODs for Sites 4 and 15. The
installation completed the proposed remedial action plan
(PRAP) and ROD for the basewide groundwater OU. The
cleanup progress at New London Naval Submarine Base for
FY02 through FY05 is detailed below.
In FY02, the installation continued groundwater monitoring at
Sites 2, 6, and 8. The Navy completed an inventory of all
Military Munitions Response Program (MMRP) sites. No MMRP
sites were identified at this installation.
In FY03, the Navy performed additional fieldwork in the
adjacent Thames River. The data was included in the feasibility
study (FS) for the lower base sites. The installation completed
the FS for the basewide groundwater OU.
In FY04, the installation completed the PRAP and ROD for the
basewide groundwater OU.
In FY05, New London Naval Submarine Base completed
remedial design for the basewide groundwater OU and for the
Site 7 Soil OU.

New London Naval Submarine completed remedial action (RA)
for basewide groundwater OU and the RA at Site 7 Soil OU.
The installation completed a draft 5-year review. Additionally,
the Navy drafted an NFA PRAP for the Defense Reutilization
and Marketing Office (DRMO) Site 6. The cost of completing
environmental restoration has changed significantly due to
technical issues.
Regulatory issues delayed the Thames River study and FS for
the lower base sites.
