Loring Air Force Base (AFB) was established in 1952 to support
B-52 bombers and KC-135 tankers. Environmental studies
began at the base in FY84. EPA placed the installation on the
NPL in February 1990 and the Air Force signed a federal facility
agreement (FFA) in April 1991, which was revised in 1994. In
July 1991, the BRAC Commission recommended closure of the
base. The flightline and nose dock areas, where industrial
shops and maintenance hangars were located, are the primary
areas where wastes were released into soil and groundwater.
Sites identified include spill areas, landfills, fire training areas,
underground storage tanks, aboveground storage tanks, and
low-level radioactive waste areas. Interim remedial actions
(RAs) were initiated in FY93 and included removal of free
product at three sites, source removal at two sites, and
treatability studies of bioventing and solvent extraction. In
FY94, an Environmental Baseline Survey was completed. The
installation formed both a BRAC cleanup team (BCT) and a
Restoration Advisory Board (RAB) in FY94. In FY98, the BCT
updated and published the BRAC cleanup plan. Five-year
reviews were completed in FY00 and FY05.
Sites at Loring AFB are grouped into 13 operable units. To
date, 12 Records of Decision have been signed, with the last 2
signed in FY99. The Air Force has transferred all property to
the Loring Development Authority (LDA). The cleanup progress
at Loring AFB for FY02 through FY05 is detailed below.
In FY02, the installation drafted a cleanup plan for
Mattawamkeag pump station and submitted it to the Maine
Department of Environmental Protection (DEP). The installation
developed an action plan for recently identified polychlorinated
biphenyl (PCB) contamination near the east branch of
Greenlaw Brook. The installation provided support to the State
and EPA for their pilot study at the former quarry. Groundwater
monitoring and the operation of soil cleanup systems continued.
Several systems were optimized based on reviews of FY01
progress.
In FY03, the installation submitted the institutional control
management plan and received comments from the Maine
DEP. Groundwater monitoring and soil cleanup systems
operations continued. A finding of suitability to transfer (FOST)

was coordinated for the 200-mile pipeline from Loring AFB to
Searsport.
In FY04, the installation completed the operating properly and
successfully determinations with EPA concurrence for all sites
at Loring AFB. Treatment systems for soil cleanups continued
to make progress towards remedial goals, and groundwater
monitoring remedies remained protective of human health and
the environment. The installation submitted property transfer
documents for concurrence. The Air Force conducted an
inventory of Military Munitions Response Program (MMRP)
sites. MMRP sites were identified at this installation.
In FY05, the installation completed the FOST for all remaining
property, which was transferred to the LDA. Operations and
monitoring continued for all remaining cleanup systems. The
installation completed the second 5-year review. RAB and BCT
activities continued. The Air Force began evaluating
requirements at MMRP sites at this installation.
p‰HT2s‚€2€�������
The installation completed the RA at the Base Laundry. The Air
Force continued to operate, monitor, and optimize remedies
across the installation. The cost of completing environmental
restoration has changed significantly due to technical issues
and changes in estimating criteria.
The installation initiated the Fuel Tank Farm RA by excavating
and land farming approximating 20,000 cubic yards of soil;
however, scheduling issues delayed completion. Future 5-year
review requirements prevented the closure of the Base Laundry
site.
p‰HT2ww‚€2€�������
The Air Force completed explosives safety certification at all
identified sites and continues to evaluate appropriate
administrative requirements.
