Site 1 - Fuel Farm Operations Area - Status
Open
IR Site 1 is made up of seven non-contiguous areas, including the existing
fuel farm. Waste petroleum, oils, lubricants (POL) and tank bottom sludges
were sprayed on vegetated areas and bare soil for weed and dust control from
the early 1940s through 1975. Polychlorinated Biphenyls (PCB) and Total
Petroleum Hydrocarbons (TPH) have been detected in samples collected at IR
Site 1C on Edson Road, the site of the new fuel farm. In addition, spills at
the fuel farm occurred. A new fuel farm is currently under construction. In preparation for the construction, a hot spot
Removal Action (RA) was carried out to remove the soil identified to have
the highest concentrations of TPH and PCBs in order to reduce the risk to
workers during the construction of the new fuel farm and to reduce the need
for special handling of soil excavated during the construction process.
Investigation and removal action for the balance of IR Site 1 will began in
FY09; completion is scheduled by FY 2011, after the existing fuel farm is
closed.

Site 2 - Rose Canyon - Status Open
During the 1940’s through the
1960’sindustrial materials were commonly discharged into Rose Canyon via
storm drains. Concentrated wastes, including oils, greases, hydraulic fluid,
fuels, solvent, paint thinners, plating waste water, corrosive wastes, and
beryllium dust were reportedly disposed of on this site. An SI is planned
for IR Site 2 in FY10.
The Fish Pond received
untreated runoff between 1952 and 1976 from air station runways, aircraft
parking aprons, and aircraft fueling stations. The untreated runoff
contained jet fuels, leaded aviation gasoline, and waste water from aircraft
washing operations. IR Site 3 was closed with No Further Action (NFA)
required following the completion of the Site Inspection (SI) in 1998.
The Drill Fields were used for
training fire fighters in the suppression of fuel and oil fires. Between
1958 and 1981, waste material, primarily fuel, was poured directly onto the
ground then ignited. Following the removal of heavy metals and
fuel-contaminated soils at this site in June and July 2005, this site was
closed with NFA required.
Between 1940 and 1974 solid
refuse and liquid wastes were staged, disposed of, and burned at IR Site 5,
which is located at the end of the main runway for the air field. Waste
materials included waste paints, pesticides, solvents, and spent lead
batteries. A Site Inspection (SI) was completed in 2006, which resulted in
the conclusion that there are large fill areas along the canyon at the end
of the runway, including a horseshoe shape around the burn area. In
addition, overshot from a local skeet range was observed in the area. A
Remedial Investigation/Feasibility Study (RI/FS) is currently being
conducted.
North Miramar Landfill was
operated by the City of San Diego between 1959 and 1983 for refuse disposal.
The site received drummed liquid waste from NAS Miramar Corrosion Control
Center between 1972 and 1983, including paint, paint thinner, paint
stripper, non-chlorinated solvents, and corrosive waste. In May 1997, IR
Site 6 was closed with NFA required by DTSC. Post-closure long-term
monitoring (LTM) is currently being conducted by the City of San Diego.
South Miramar Landfill was
operated by the City of San Diego between 1959 and 1972 and may have
received industrial wastes during this time, including paints, oils, and
strong acids. In May 1997, DTSC closed IR Site 7 with NFA required.
Post-closure LTM is currently being conducted by the City of San Diego.
The Old Camp Elliott Heating
Plant was built in the 1940’s and operated until 1960. Asbestos insulation
that coated the plant’s eight boiler tanks and ancillary piping had
deteriorated and fallen to the floor creating an asbestos dust hazard. The
deteriorated materials and effected soils were removed and properly disposed
of during site cleanup in 1985 in conjunction with the demolition of the
plant. Upon final SI, regulatory officials closed IR Site 8 with NFA
required in April 1997.
IR Site 9 consisted of former
munitions ranges and impact areas east of I-15. These areas were originally
included in the IR Program, but were removed because, although no longer
used as munitions impact areas, they remain operational ranges.
Responsibility for the site was transferred to the Munitions Response
Program.
Between late 1955 and late
1960’s Atlas Missile booster testing was conducted by the National
Aeronautics and Space Administration (NASA) and the U.S. Air Force.
Following closure of the facility, the site was vandalized and several
electrical transformers containing PCBs were damaged. In addition, asbestos
contamination was addressed by a removal action in 1994. An SI was finalized
in 2006 resulting in the discovery that, in addition to PCB contamination of
soil at the site, PCBs were found on a nearby access road to an Explosive
Ordnance Disposal site. An Engineering Evaluation/ Cost Analysis (EE/CA) is
currently underway at IR Site 10 and a Removal Action is planned for
FY09.
Soil along a natural drainage
ditch at the intersection of Miramar Way and Nomad Road received
contamination when an oil/ water separator malfunctioned and clogged. The
oil/ water separator was associated with the Auto Maintenance Facility, the
Truck Maintenance Facility, and Pesticide Mixing and Storage Facility.
Following cleanup of the site in 1995, IR Site 11 was closed with NFA
required in December 1996.
A natural drainage ditch
southwest of the Navy Exchange Main Gas Station received contamination from
the runoff of a clogged oil/ water separator located at the Auto Hobby Shop.
Site cleanup was conducted in 1995 and IR Site 12 was closed in December
1996 with NFA required.
Soils comprising a natural
drainage ditch were contaminated following a clog in an oil/water separator
at the Aviation Intermediate Maintenance Department (AIMD). Wastes were a
result of aircraft engine testing, solvent cleaning of engine components,
and engine repair and maintenance operations. Site cleanup was conducted in
1995. Site closure was achieved in December 1996 with NFA required.
IR Site 14 is comprised of a
drainage ditch in close proximity to Hangar 6 on MCAS Miramar’s flight line.
In August 1996, contaminated soils were removed from the site and it was
determined that any residual contamination did not pose a significant threat
to groundwater and surface water. This IR Site was closed with NFA required
on December 6, 1996.
IR Site 15 is located adjacent
to Building 238. Prior to 1992, this site was used as the hazardous waste
storage area. Soil contamination resulted from spills associated with
storage of waste fuels, solvent rags, and waste oils. An SI to assess the
contamination at the site is scheduled for FY10.
IR Site 16 is located adjacent
to the K212 Boiler Plant. During a tank excavation, evidence was found of a
mercury release. Soil contamination on the site most likely resulted from
broken mercury manometers and leaking waste tanks. An SI to assess the
contamination at IR Site 16 is scheduled for FY10.
Building 8380 was constructed
in 1959 and was use as a photo imaging laboratory. Leaking sumps beneath the
building contaminated soil in the immediate area with photo processing
chemicals. The site was added to the IR Program in 1996. Following analysis
of soil samples, the IR Site was closed in November 1998 upon concurrence by
the RWQCB with the findings in the Preliminary SI, which reported low risk
to human health.
The NEX Main Gas Station is the
primary service station on Air Station for nonmilitary vehicles. It is
located near the intersection of Miramar Court and Maxam Way, near the
western entrance to MCAS Miramar. Leaking gasoline and Underground Storage
Tanks (USTs) contaminated soil and groundwater in the immediate area.
Following a 1997 directive, subsequent sampling indicated groundwater
beneath the site had been impacted with petroleum hydrocarbons; contaminated
soil was excavated and disposed of offsite. Groundwater sampling conducted
in early 2007 indicates that additional investigation is required to assess
the extent of groundwater contamination. Additional groundwater assessment
activities are planned for FY09.
