Moffett Field Naval Air Station (NAS) was headquarters of the
Commander, Patrol Wings U.S. Pacific Fleet. Responsible for
submarine patrol operations across the Pacific, NAS Moffett
Field was the largest P-3 base in the world. In July 1991, the
BRAC Commission recommended closure of the installation.
The installation was closed on July 1, 1994 and transferred to
NASA. The Naval Air Manor property was transferred to a
neighboring city. The associated Moffett Community Housing
(MCH) was transferred to the Army. EPA placed the installation
on the NPL in July 1987. The Navy signed a federal facility
agreement (FFA) in FY90, amended it in FY94, and revised it in
FY01. Sites at the installation include landfills, underground
storage tanks, a burn pit, ditches, holding ponds, wetland
sediments, French drains, maintenance areas, and fuel spill
sites. Contaminants include polychlorinated biphenyls (PCBs),
petroleum products, DDT, chlorinated solvents, and heavy
metals. The installation was divided into seven operable units
(OUs). The installation completed a community relations plan
(CRP) and established an information repository in FY89. In
FY94, it formed a BRAC cleanup team and completed a BRAC
cleanup plan, which was updated in FY97. The installation
converted its technical review committee to a Restoration
Advisory Board (RAB) in FY95. A RAB forum for the Bay Area
Community was held and the CRP was updated in FY02. In
FY03, the installation completed 5-year review reports for two
groundwater remedial sites.
Environmental studies have identified 34 sites at the
installation. In addition, the installation has completed several
No Further Action (NFA) Records of Decision (RODs). The
installation has also completed RODs for OU 1, Sites 22, 26,
27, and 28. The installation has completed closure of 35
petroleum sites. The cleanup progress at Moffett Field NAS for
FY02 through FY05 is detailed below.
In FY02, the installation completed closure of 35 petroleum
sites. The ROD and remedial design (RD) for Site 22 were
completed, as well as the proposed plan (PP) and ROD for the
NFA sites. The installation submitted 5-year review reports for
OU 1, and Sites 1 and 2 to regulatory agencies. Progress
continued on the site management plan for delisting Moffett
Field from the NPL. Support of the NASA-Navy memorandum
of agreement (MOA) continued. The installation initiated an
Navy

optimization study for Sites 26 and 28 pump-and-treat systems.
A human health risk assessment (HHRA) on MCH started due
to groundwater contamination. The Navy completed an
inventory of all Military Munitions Response Program (MMRP)
sites. No MMRP sites were identified at this installation.
In FY03, the installation completed a 5-year review report for
both the westside and eastside aquifer treatment systems.
Additionally, the installation completed the PP for Site 25 and
initiated a time-critical removal action (TCRA) at the new source
area, Hangar 1. The installation completed the feasibility study
(FS) for Site 27 and the remedial action (RA) for Site 22. The
HHRA at MCH was completed, although additional studies are
needed to supplement HHRA. An additional seven petroleum
sites were closed.
In FY04, the installation completed the Hangar 1 TCRA and
started work on the remedial investigation (RI) and FS work
plan for Hangar 1. The installation completed the Site 27 PP.
Optimization of the Sites 26 and 28 pump-and-treat systems
began. The installation completed air sampling at MCH and a
work plan drafted for the final phase of groundwater
investigation. The installation received closure letters for
petroleum sites from the California Regional Water Quality
Control Board.
In FY05, the installation finalized the Moffett Field NAS Site 25
RI report addendum and submitted the draft FS report
addendum for agency review and comment. The Navy finalized
the Site 27 ROD and began the RD for RA. The installation
continued the site management plan for delisting Moffett Field
from the NPL and support of the NASA-Navy MOA.
p‰HT2s‚€2€�������
Moffet Field NAS developed and submitted an FS for Site 25.
The installation also completed and implemented the Site 27
RD, and implemented optimization of the Site 26
pump-and-treat system. The Navy continued resolution of
groundwater contaminant responsibility. The cost of completing
environmental restoration has changed significantly due to
technical issues, regulatory issues, and changes in estimating
criteria.
Regulatory issues delayed the PP and ROD for Site 25.
Regulatory issues also delayed removal action at Site 29. In
addition, procedural issues delayed RA for Site 27.
p‰HT2ww‚€2€�������
The Navy has identified no MMRP sites at this installation.
