The Naval Auxiliary Landing Field (NALF) at Crows Landing
was commissioned in May 1943, and served primarily as an
auxiliary airfield. The installation established an information
repository in FY89. In July 1991, the BRAC Commission
recommended closure of NALF Crows Landing. The installation
was closed on July 1, 1994, and was transferred to NASA in
FY94. In FY94, the installation formed a BRAC cleanup team
(BCT) and completed a BRAC cleanup plan, which was
updated in FY97. The installation developed an environmental
business plan and a community relations plan (CRP), both of
which were updated in FY01. The CRP was updated again in
FY02.
To date, regulatory oversight agencies have concurred on no
further action (NFA) status for eight Installation Restoration
Program (IRP) sites. Congress authorized NASA to transfer the
facility to Stanislaus County in FY99. The cleanup progress at
NALF Crows Landing for FY02 through FY05 is detailed below.
In FY02, groundwater extraction and monitoring activities
continued at two source areas at the Administration Area Plume
(Site 17). The installation completed corrective actions at
underground storage tank (UST) Cluster (CL) 1, and removed a
total of 22,000 pounds of petroleum hydrocarbons from the
vadose zone. Information gathering for closure reports began
for UST sites. The Navy completed an inventory of all Military
Munitions Response Program (MMRP) sites. The installation
continued to provide for community involvement, published four
fact sheets, updated the CRP, and maintained the local
information repository in Patterson, California. BCT meetings
were conducted bimonthly.
In FY03, the Navy continued groundwater extraction activities
and removed more than 280 pounds of contaminant mass
(primarily acetone and gasoline) from the Administration Area
Plume (Site 17). The installation completed closure reports for
UST CL 7 and UST CL 40, and the regulatory closure of those
sites. Information was collected for the revised feasibility
studies for Sites 11 and 17. The administrative record and
information repository were maintained. Plans for an in situ
submerged oxygen curtain (iSOC) groundwater treatment
demonstration project were completed. NFA status was
achieved for UST CL 7 and UST CL 40. Approximately 19,000

tons of waste and construction debris were removed from IRP
Site 11A (sewer systems) during a time-critical removal action
(TCRA). A draft engineering evaluation and cost analysis,
explosive safety submittal, and a work plan for a TCRA to
remove approximately 14,000 tons of buried waste, ordnance,
and construction debris from IRP Site 11 were completed. Five
fact sheets were sent to the community members and other
recipients on the CRP mailing list. The BCT meetings were
conducted bimonthly.
In FY04, the Navy continued groundwater extraction activities
near the site of a former dry well at the Administration Area
Plume (Site 17). In addition, a demonstration project was
conducted using iSOC within Site 17. The installation prepared
a plan to conduct a groundwater investigation on the adjacent
(downgradient) property and began development of the access
agreement. The installation conducted routine groundwater
monitoring activities and munitions evaluations at IRP Site 11.
The Navy initiated investigating and response actions at Site
11A. The installation issued four fact sheets and three public
notices. The BCT meetings were conducted bimonthly. The
BCT continued to partner, evaluating environmental cleanup as
well as approving the environmental master schedules for the
installation.
In FY05, NALF Crows Landing completed the transitional
groundwater extraction near the former dry well at the
Administration Area Plume (Site 17). In addition, the
investigation of groundwater beneath adjacent property at Site
17 was completed. The installation received regulatory closure
on USTs 109 and 117, as well as the CL 2 area. Munitions and
explosives of concern evaluations began in four areas at the
installation. The iSOC demonstration project within Site 17 was
completed. NALF Crows Landing issued an environmental
business plan. The BCT continued to partner, evaluating the
environmental program as well as approving the environmental
master schedules for the installation. The installation issued two
fact sheets, two public notices, and updated the CRP. NALF
Crows Landing held a public meeting and completed the
removal action at Site 11 (disposal pits).

NALF Crows Landing continued basewide groundwater
monitoring at the installation, and prepared a TCRA action
g����2v—�����D2g—�������—
memorandum for excavation and confirmation sampling at IR
Site 11B. The installation prepared a work plan for additional
investigation at the adjacent property (Site 17).
The installation began an interim remedial action (IRA)
alternative evaluation for Site 17; however, procedural issues
delayed its completion.
