STATEMENT OF BASIS AND PURPOSE
This decision document presents the selected remedial action for Sites 4, 6, 9, 10, 13, 15,
19, 20, 21, 22, and 25 at MCAS El Toro in Orange County, California. The document
was developed in accordance with the Comprehensive Environmental Response,
Compensation; and Liability Act of 1980 (CERCLA), as amended by the Superfund
Amendments and Reauthorization Act of 1986 and, to the extent practicable, the National
Oil and Hazardous Substances Pollution Contingency Plan. This decision is based on the
administrative record file for these sites.
The State of California (through the California Environmental Protection Agency,
Department of Toxic Substances Control, and Santa Ana Regional Water Quality Control
Board) and the U.S. Environmental Protection Agency concur with the selected remedy.
DESCRIPTION OF THE SELECTED REMEDY: NO ACTION
The selected remedy for Sites 4, 6, 9, 10, 13, 15, 19, 20, 21, 22, and 25 is no action. In
selecting the no action remedy for these sites, the Navy has determined that the existing
condition of the sites is protective of human health and the environment.
Although no deed restrictions are required because of chemicals present in soils at the no
action sites, shallow groundwater underlying Sites 9, 10, 13, 15, 21, 22, and portions of
Site 25 is contaminated by trichloroethene and tetrachloroethene. Remedial
investigations have shown that the contamination does not originate from these sites but
from Site 24, the volatile organic compound source area. Use restrictions for several sites
(including Site 24 and the no action sites listed above) prohibiting drilling of wells and/or
extraction of groundwater and allowing access for groundwater monitoring and
maintenance of equipment associated with groundwater remediation will be addressed in
the Proposed Plan(s) and Record(s) of Decision for Operable Unit-1 and -2A regarding
groundwater.
DECLARATION STATEMENT
Based on extensive field investigations, laboratory analyses, and a thorough assessment
of potential human-health risks at each location and of potential ecological risks at
Site 25, the Navy has determined that no remedial action is necessary to assure the
protection of human health and the environment at Sites 4, 6,9, 10,13, 15, 19,20,21,22,
and 25. The Remedial Investigations of these sites show that contamination is limited to
the shallow soil interval (Sites 4, 6, 9, 10, 13, 15, 19, 20, 21, and 22) and to sediment and

surface water (Site 25). The human health and ecological risk assessments show that the
chemicals present in these media do not present an unacceptable risk to human health or
the environment. Therefore, no remedial action is required at these sites. Since
hazardous substances are not present at concentrations above unacceptable levels,
CERCLA Section 121 cleanup standards do not apply.

1.2 SITE LOCATION
MCAS El Toro lies in a semiurban agricultural area in southern California, approximately
8 miles southeast of the city of Santa Ana and 12 miles northeast of the city of Laguna
Beach (Figure 1-1). Land northwest of the Station is used for agricultural purposes. The
land to the south and northeast is used mainly for commercial, light industrial, and
residential purposes. Sites 4, 6, 9, 10, 13, 15, 19, 20, 21, 22, and 25 are located
throughout the Station as shown in Figure 1-2.
1.3 SITE DESCRIPTION
MCAS El Toro is located on the Tustin Plain, a broad alluvial valley. The Station
comprises runways, aircraft maintenance and training facilities, housing, shopping
facilities, and other support facilities totaling 4,478 acres. OU-3A no action site
elevations range from approximately 240 to 400 feet above mean sea level and are
located adjacent to the runways and other industrialized areas of the Station. Each of the
OU-3A sites is relatively flat. Most of the sites are covered by asphalt, concrete, or hard-
packed soil that is partially vegetated. None of these sites contains any significant
ecological habitat. With the exception of Site 12 (immediately adjacent to an exposed

portion of Bee Canyon Wash), the OU-3A no action sites are not adjacent to the exposed
portions of any of the major drainages that direct surface runoff away from the Station.
More complete descriptions of each of the OU-3A no action sites are found in Table 1-1.
OU-2A Site 25 consists of four main drainage channels that flow through or adjacent to
the station. The channels are Agua Chinon Wash, Bee Canyon Wash, Borrego Canyon
Wash, and Marshburn Channel (Figure 1-2). Three of these drainages are continuations
of natural washes that originate in the Santa Ana Mountains (Agua Chinon Wash, Bee
Canyon Wash and Borrego Canyon Wash). Surface drainage from the hills and
upgradient irrigated farmland combines with runoff generated from extensive paved
surfaces on the Station. The on-Station storm sewer system discharges into the drainage
channels, which then flow into San Diego Creek. San Diego Creek discharges into Upper
Newport Bay, about 7 miles downstream from its intersection with Marshburn Channel.
The channels are mostly lined and/or culverted through the Station. Surface water quality
in the channels is monitored in accordance with National Pollutant Discharge Elimination
System (NPDES) requirements (Order No. 93-16, NPDES No. CA 0106593).
1.4 GEOLOGY AND HYDROGEOLOGY
MC AS El Toro lies on the southeastern edge of the Tustin Plain, a gently sloping surface
of alluvial fan deposits derived mainly from the Santa Ana Mountains. These Holocene
materials consist of isolated coarse-grained, stream-channel deposits contained within a
matrix of fine-grained overbank deposits that range in thickness up to 300 feet (Hemdon
and Reilly 1989). Silts and clays predominate in the central and northwestern portion of
the Station. Sands are more common near the foothills. The sands are predominantly
well graded (poorly sorted), ranging from coarse to fine, and commonly contain clay
lenses. Clays exhibit medium plasticity and contain sand (Jacobs Engineering 1993a).
The Station lies within the Irvine Groundwater Subbasin (Irvine Subbasin), which has
been designated by the California Regional Water Quality Control Board (RWQCB),
Santa Ana Region, as a public water supply source (RWQCB 1995). The regional aquifer
beneath MCAS El Toro is not currently a source of municipal drinking water; however,
groundwater in the vicinity of the Station is used for agricultural purposes. One on-
Station groundwater well that belongs to the Irvine Company, located at the westernmost
end of the east-west runway, is used for irrigation and is connected to the regional
irrigation distribution system. Other wells pumping irrigation water are located west
(three wells) and northwest (four wells) of the Station. The closest agricultural well is
18_TIC111, which is adjacent to the northwest Station boundary. To the west, the
nearest well is 18_TIC047, which is located approximately 2,600 feet west of the Station
boundary.
Water is first encountered at 95 to 225 feet below ground surface at the OU-3A sites
(Table 1-1). Review of water-level and water-quality data for multiple-port monitoring
wells and cluster wells throughout the Irvine Subbasin suggests some hydraulic
separation may exist between the shallower and deeper portions of the regional

groundwater aquifer. According to 1993 water levels, the direction of flow along the
southwest boundary of MCAS El Toro was northwest (Figure 1-3) at a gradient of
approximately 0.008 (Jacobs Engineering 1993a). Regional flow has been west and
northwest since the 1940s and has been controlled locally by large pumping depressions.
The average linear groundwater-flow velocities in the uppermost aquifer across MCAS El
Toro are in the range of 0.02 to 1.9 feet per day (JMM 1990).
1.5 SURFACE HYDROLOGY
Surface drainage near MCAS El Toro generally flows southwest, following the slope of
the land and perpendicular to the trend of the Santa Ana Mountains. Several washes
originate in the hills northeast of MCAS El Toro and flow through or adjacent to the
Station en route to San Diego Creek. Off-Station drainage from the hills and upgradient
irrigated farmlands combines with Station runoff at MCAS El Toro (generated from the
extensive paved surfaces) and flows into four major drainage channels: Borrego Canyon
Wash, Agua Chinon Wash, Bee Canyon Wash, and Marshburn Channel. These
on-Station drainages comprise IRP Site 25.
The southernmost wash is Borrego Canyon Wash, which flows along the southeast
boundary of MCAS El Toro (Figure 1-2). The wash is unlined in the Santa Ana
Mountains; downstream of Irvine Boulevard, it is lined. Borrego Canyon Wash crosses
the southern corner of the Station and joins Agua Chinon Wash about 1/4 mile
downstream of the Station boundary.
Both the Agua Chinon and the Bee Canyon Washes cross the central portion of MCAS El
Toro and receive on-Station runoff mainly through storm sewers (Figure 1-2). These
washes are contained in culverts through most of their pathways across the Station. Both
washes are unlined along several hundred feet at the southwest edge of the Station and are
lined and culverted downstream of the Station. Agua Chinon Wash flows into San Diego
Creek just east of the intersection of the San Diego and Laguna Beach Freeways, about 1
mile downstream of its confluence with Borrego Canyon Wash. Bee Canyon Wash flows
into San Diego Creek just northeast of the same intersection, about 1,500 feet north of
Agua Chinon Wash.
Marshburn Channel is a lined drainage channel that runs along the northwestern boundary
of MCAS El Toro. The channel receives runoff from upstream agricultural fields and
from the western part of the Station (Figure 1 -2) and discharges into San Diego Creek
about 3/4 mile northwest of Bee Canyon Wash.
1.6 CURRENT LAND USE
MCAS El Toro is bordered on the south and west by the city of Irvine and on the north
and east by unincorporated lands. The city of Irvine controls development in surrounding
areas that are suitable for urbanization. However, local jurisdictions do not have
authority over federal lands.

Section 1 Site Name, Location, and Description
MCAS El Toro encompasses about 4,738 acres. Approximately 1,000 acres are
designated for outleases that are not available for development because airfield safety
clearances render them unsuitable for any other use. The outleased lands are at the
corners of the Station and are used for agricultural purposes, including landscape
nurseries, livestock grazing, and crop production.
Land use on MCAS El Toro consists of a few general types. General Station land uses
are described in the following four quadrants, as defined by the bisecting north-south and
east-west runways.
• The northwest quadrant consists of administrative services (including the
MCAS El Toro headquarters, family and bachelor housing, and community
support services).
• The northeast quadrant consists of Marine Aircraft Group activities (including
training, maintenance, supply and storage, and airfield operations), family
housing, community services, and ordnance storage in areas isolated by
topographic relief and distance from other developments.
• The southeast quadrant consists of administrative services, maintenance
facilities, ordnance storage, and the golf course.
• The southwest quadrant consists of aircraft maintenance facilities, supply and
storage facilities, and limited administrative services.
MCAS El Toro continues to provide materials and support for aviation activities of the
United States Marine Corps. The current land use of each of the 11 sites included in this
Record of Decision (ROD) is described on Table 1-1.
Historically, land use around MCAS El Toro has been largely agricultural. However, the
land to the south, southeast, and southwest has been developed over the past 10 years for
commercial, light-industrial, and residential uses. Currently, expanding commercial areas
are located adjacent to the Station. Additional residential areas are located to the
northwest and west of the Station. Adjacent land to the northeast and northwest is used
for agriculture.
Growth projections through the year 2000 for the area surrounding the Station indicated
continued urbanization. The estimated population in the city of Irvine in 1990 was
105,311. Population projections indicate further increases to 118,570 by the year 2000
and 208,220 by the year 2020. Population growth has occurred primarily in the central
residential districts within 2 to 3 miles of the Station.
1.7 FUTURE LAND USE
MCAS El Toro is scheduled for closure in 1999. A Community Reuse Plan has been
prepared (MCAS Local Redevelopment Authority 1996). This plan is a conceptual,
policy-level reuse plan. A more detailed master plan shall be developed as a second
phase of reuse planning and will identify more site-specific land uses. The preferred
alternative selected in the December 1996 Community Reuse Plan was a major airport

Section 2
SITE HISTORY AND ENFORCEMENT ACTIVITIES
MCAS El Toro was commissioned in March 1943 as a Marine Corps pilot fleet operation
training facility. In 1950, the Station was selected for development as a master jet station and
permanent center for Marine Corps aviation on the west coast to support the operations and
combat readiness of Pacific Fleet Marine Forces. Since its commissioning, MCAS El Toro has
been used for aviation activities. Other historical activities have generated waste oils, paint
residues, hydraulic fluid, used batteries, and other wastes (MCAS El Toro 1991). Since 1985,
when trichloroethene (TCE) was discovered in an irrigation well located approximately
3,000 feet downgradient of MCAS El Toro, the Navy has taken actions to assess the effects of its
activities on the surrounding environment and to remediate areas adversely affected by these
activities.
Environmental cleanup activities at MCAS El Toro are performed under the Navy IRP. The IRP
was developed in 1980 by the Department of Defense (DoD) to comply with federal guidelines
to manage and control past hazardous waste disposal actions (DON 1992). From the time TCE
contamination was reported in 1985, both the RWQCB and the Department of Toxic Substances
Control (DTSC) have been involved in overseeing the investigation and cleanup work done by
the Department of the Navy (DON) at this site.
In 1985, the Navy began work on an Initial Assessment Study (IAS) to locate potentially
contaminated sites on the Station. This work was conducted for the Naval Facilities Engineering
Command under the Navy Assessment and Control of Installation Pollutants Program, which
was the Navy version of the DoD IRP at that time. The I AS report identified 17 sites as potential
sources of contamination (Brown and Caldwell 1986). The identification of potentially
contaminated sites was based on the results of record searches and employee interviews. The
report recommended sampling locations and analytical parameters to confirm the suspected
contamination at the sites.
In 1987, the Marine Corps contracted for a review of the IAS to produce a Site Inspection Plan of
Action (SIPOA) (JMM 1988). In July 1987, while the SIPOA study was underway, the RWQCB
Santa Ana Region issued a cleanup and abatement order to the Marine Corps. This order
required the Station to initiate a perimeter groundwater volatile organic compound (VOC)
investigation and submit a draft report. The SIPOA released in August 1988 included a
recommendation of 19 sites for study, and it amended the site sampling plans proposed in the
IAS report. This SIPOA report served as the basis for the Sampling and Analysis Plan for the
Remedial Investigation (RI)/feasibility study (FS) sites.
In June 1988, the United States Environmental Protection Agency (U.S. EPA) recommended
adding MCAS El Toro to the National Priorities List (NPL) of the Superfund Program because of
the presence of VOC contamination at the Station boundary and the detection of VOCs in the
agricultural wells west of the Station. MCAS El Toro was added to the NPL on 15 February
1990. In October 1990, the Marine Corps/Navy signed a Federal Facilities Agreement (FFA)
with the U.S. EPA Region IX California Department of Health Services (now referred to as the

Section 2 Site History and Enforcement Activities
California Environmental Protection Agency (Cal-EPA) DTSC, and the California RWQCB
Santa Ana Region (FFA 1990). The FFA is a cooperative agreement that:
• assures environmental impacts are investigated and appropriate response
actions are taken to protect human health and the environment;
• establishes a procedural framework and schedule for developing, implementing,
and monitoring appropriate response actions;
• facilitates cooperation, exchange of information, and participation of the
parties; and
• assures adequate assessment, prompt notification, and coordination between
federal and state agencies.
The implementation of the FFA is included as one of the responsibilities of the Base
Realignment and Closure (BRAC) Cleanup Team (BCT). The BCT consists of representatives
from the DON Southwest Division Naval Facilities Engineering Command (SWDIV), U.S. EPA,
DTSC, and RWQCB Santa Ana Region. The team was established to manage and coordinate
environmental restoration and compliance programs related to the closure and disposal of MCAS
El Toro by July 1999. In addition, the MCAS El Toro BCT has specified in its mission and
vision statements that:
• fast-track remediation of sites is necessary to expedite reuse; and
• restoration and reuse is to be maximized by 1999.
In December 1989, the Navy began to prepare a Phase I RI Work Plan and associated documents
for MCAS El Toro. The Navy reviewed the available reports and other documents pertinent to
past disposal practices at the Station and concluded that 22 sites would be investigated (Jacobs
Engineering 1993a). These sites were grouped into three OUs. OU-1 comprised the regional
VOC groundwater investigation (Site 18), which was conducted both on and off the Station.
OU-2 included the four landfill sites (Sites 2,3,5, and 17) considered to be potential source areas
for the regional groundwater VOC contamination and Site 10, the petroleum disposal area (this
site was later moved to OU-3). The remaining 16 sites were grouped together as OU-3. These
sites were considered to be potential sources for a variety of contaminants. The principal
objectives of the Phase I RI were to evaluate the source(s) of contamination in regional
groundwater west of the Station and determine whether contamination exists and is affecting the
environment at sites in OU-2 and OU-3.
In March 1993, MCAS El Toro was placed on the Base Closure and Realignment Act III list of
military facilities considered for closure. Under the terms of the FFA, Station closure would not
affect the Navy's obligation to conduct the RI/FS and to comply with the other requirements of
the FFA (FFA 1990, Section 37, Base Closure).
The results of the Phase I RI were documented in a draft Technical Memorandum issued in July
1993 (Jacobs Engineering 1993a) and in a draft RI report for OU-1 issued in July 1994 (Jacobs
Engineering 1994a). A variety of contaminants in the groundwater, soil, surface water, and
sediment at MCAS El Toro were identified during the Phase I RI. Contaminants in the soil and
sediment consisted primarily of low concentrations of semivolatile organic compounds (SVOCs),

petroleum hydrocarbons, pesticides, herbicides, and polychlorinated biphenyls (PCBs) (Jacobs
Engineering 1993a). It was also concluded during the Phase I RI that the source of
contamination for regional groundwater is in the southwest quadrant of the Station, but no
specific sources were identified. The sampling events yielded sufficient information to warrant
conducting a preliminary risk assessment of contaminants at the sites for both groundwater and
soil contamination. The results of the Phase I RI provided the primary data for the Phase II
RI/FS.
Concurrent with the Phase I RI, the Navy conducted a Resource Conservation and Recovery Act
(RCRA) Facilities Assessment (RFA) at MCAS El Toro. The purpose of the RFA was to
evaluate whether an additional 140 sites at MCAS El Toro would require further investigation
under the Phase II RI/FS program. The final RFA report was submitted in July 1993 (Jacobs
Engineering 1993b). Based on an evaluation of the sampling visit results, 25 solid waste
management units (SWMUs)/areas of concern (AOCs) were recommended for further action.
Site 23 (Wastewater Treatment Plant Sewer Lines) was evaluated in the RFA and recommended
for no further action. The sewer lines are located within Site 24, which was added to the Phase II
scope.
Interviews with active and retired personnel from the Fuel Operations Division and Facility
Management Department (currently the Installations Department) were held in July 1994 at
MCAS El Toro (Jacobs Engineering 1994b). The objectives of the meeting were to supplement
and confirm information obtained from past interviews and field investigations, to obtain a better
understanding of current and historical operations at MCAS El Toro, and to identify new areas of
potential environmental concern at MCAS El Toro. Those interviewed had knowledge of
operations and procedures for storage and disposal of hazardous materials and waste. The
interview panel consisted of regulatory agency personnel, Navy and MCAS El Toro personnel,
and contractor personnel.
The subjects covered during the interviews included underground storage tanks (USTs),
aboveground storage tanks, RI/FS investigation sites, tank farms, disposal procedures, disposal
areas, and any accidental or unintentional spills or leaks that may have occurred. Much of the
information gathered form previous interviews and field investigations was confirmed. The
interview panel discussed the types of wastes deposited in each of the landfills, the depth and the
boundaries of the landfills, and how the wastes were handled. Other subjects discussed included
the types of operations that occurred on the Station and the types of chemicals used in these
operations.
In July 1995, a final Work Plan for the Phase II RI/FS was issued (BNI 1995). This Work Plan
presented an approach to conduct the Phase II RI at 24 sites, including two new sites, Site 24 and
Site 25. The objectives of the plan were to present a statistically based sampling strategy to
numerically establish confidence that inferences made from the data are correct, establish
background concentrations of metals in soils and, ultimately, collect sufficient information to
support risk management decisions. The Phase II RI was conducted in 1995 and 1996.

MCAS El Toro was placed on the
BRACk III list. Under the terms of the
FFA1, Station closure would not affect
the Navy's obligation to conduct the
RI/FS"1 and comply with the other
requirements of the FFA.
Various contaminants in the
groundwater, soil, surface water, and
sediment were detected at MCAS El
Toro. Soil and sediment contaminants
were primarily SVOCs", petroleum
hydrocarbons, pesticides, herbicides,
and PCBs". The Phase I RI concluded
that the source of contamination for
regional groundwater was the southwest
quadrant of the Station, but it did not
indicate specific sources. A preliminary
risk assessment was conducted for
contaminants at the sites in both
groundwater and soil.
Based on the RCRA Facility Assessment
results, SWMUs/AOCsq were
recommended for further action. This
action included additional subsurface
investigation or other activities such as
inspection of underground storage tanks,
repair of cracks in concrete-paved areas,
and excavation of contaminated soil. Of
these 25 SWMUs/AOCs, 2 were
recommended for further action under
the Phase II RI/FS program. Site 23 was
investigated and recommended for no
further action.
The soil gas survey investigated soil
conditions (generally 12 to 20 feet
below ground surface). Elevated
concentrations of VOCs were detected
beneath the aircraft maintenance hangars
(Buildings 296 and 297). TCE was the
dominant compound detected. Other
VOCs detected included PCE, 1,1-
dichloroethene, Freon 113, carbon
tetrachloride, and chloroform.

HIGHLIGHTS OF COMMUNITY PARTICIPATION
Twenty-four IRP sites are being investigated at MCAS El Tore. A Community Relations Plan
(BNI 1996a) was developed to document concerns identified during community interviews and
to provide a detailed description of the community relations activities planned in response to
information received from the community. The initial plan was prepared in 1991 and revised in
1993 and 1996. The revisions incorporated the most recent assessment of community issues,
concerns, and information needs related to the ongoing environmental investigation and
remediation program at MCAS El Toro.
The community relations program includes specific activities for obtaining community input and
keeping the community informed. These activities include conducting interviews, holding public
meetings, issuing fact sheets to provide updates on current remediation activities, maintaining an
information repository where the public can access technical documents and program
information, disseminating information to the local and regional media, and making
presentations to local groups.
Outside of the community relations program, community members and local governmental
agencies have participated in planning for the reuse of MCAS El Toro through development of
the Community Reuse Plan.
3.1 RESTORATION ADVISORY BOARD
In 1994, individuals from local communities began to play an increasingly significant
role in the environmental restoration process with the establishment of the Restoration
Advisory Board (RAB). Original membership in the board, which was solicited by the
Marine Corps/Navy through paid newspaper notices, exceeded 50 business and
homeowners' representatives, local elected officials and regulatory agencies, and
interested residents. RAB meetings occur every 2 months, are open to the public, and
include interested representatives from the Marine Corps/Navy, city and county offices,
and regulatory agencies. Several board members from the RAB have taken information
from the regular meetings back to the groups they represent, thus contributing to an
increased awareness of the IRP process. In addition, members of the public can contact
RAB members to obtain information or express concerns to be discussed at subsequent
RAB meetings. A copy of the RAB meeting minutes is available at the MCAS El Toro
Information Repository, located at the Heritage Park Regional Library in Irvine,
California. RAB meeting minutes are also located on the Navy's SWDIV Environmental
Web Page, which can be found at either of the following two Internet addresses:

3.3 COMMUNITY PARTICIPATION FOR NO ACTION SITES
The draft final RI report and the Proposed Plan for OU-3A and Site 25 were released to
the public in June 1997. These documents were made available to the public at the
information repository maintained at the Heritage Park Regional Library in Irvine,
California. The notice of availability for these documents was published in the Orange
County Register and the Los Angeles Times (Orange County Edition) on 10 June 1997.
The notices also announced the availability of the administrative record file for review.
Complete administrative record files are available at the SWDIV in San Diego and at
MCAS El Toro. A partial record file is available for review at the information repository.
The information repository also contains a complete index of the administrative record
file along with information about how to access the complete file at the Station. The
Proposed Plan was also distributed to the MCAS El Toro project mailing list.
A public comment period was held from 16 June to 16 August 1997. In addition, a public
meeting was held on 31 July 1997. This meeting was announced in the Orange County
Register and Los Angeles Times (Orange County Edition) on 24 July 1997. Media alerts

were also used to notify the reporters that the public was invited to the meeting and to
encourage the reporters to attend and publicize the event. At this meeting, representatives
from the DON, MCAS El Toro, and environmental regulatory agencies answered
questions about site conditions and the remedial alternatives under consideration and a
public recorder recorded verbal public comments. A response to the comments received
during this period is included in the Responsiveness Summary, which is part of this ROD.
This decision document presents the selected remedial action for IRP Sites 4, 6, 9, 10, 13,
15, 19, 20, 21, 22, and 25, MCAS El Toro in Orange County, California. The document
was developed in accordance with the Comprehensive Environmental Response,
Compensation, and Liability Act of 1980 (CERCLA), as amended by the Superfund
Amendments and Reauthorization Act of 1986 and the National Oil and Hazardous
Substances Pollution Contingency Plan. The decision for these sites is based on the
information contained within the administrative record. The administrative record index

SCOPE AND ROLE OF OPERABLE UNIT
There are 24 IRP sites assigned to three OUs at MCAS El Toro. OU-1 encompasses Site 18
(Regional Groundwater). OU-2 is subdivided into OU-2A, OU-2B, and OU-2C. OU-2A
encompasses Site 24 (VOC Source Area) and Site 25 (Major Drainages). Area OU-2A was
defined to address the source of regional groundwater contamination. Site 25 was included in
this OU because it was not known whether the major drainages at MCAS El Toro were acting as
a source of the VOC contamination that is found in the shallow groundwater unit beneath the
Station and in the principal aquifer off-Station. The Phase II RI of Site 25 showed that:
1) Site 25 is not a source of regional groundwater contamination; and 2) risks to human health
and the environment at Site 25 are acceptable. Therefore, the Phase II RI concluded that no
further action is required at Site 25. Site 25 is being addressed in this ROD. Sites 18 and 24 will
be addressed in separate RODs.
OU-2B encompasses Sites 2 and 17. OU-2C encompasses Sites 3 and 5. Sites 2, 17, 3, and 5 are
generally referred to as the landfill sites. Sites 2, 17, 3, and 5 are being addressed in two separate
RODs.
OU-3 was defined to address the remaining IRP sites at MCAS El Toro. OU-3A contains
thirteen sites. Ten of these sites (Sites 4, 6, 9, 10, 13, 15, 19, 20, 21, and 22) were investigated,
found to contain no unacceptable risks to human health or the environment, and were
recommended for no action. These sites are addressed in this ROD. The remaining three OU-3A
sites (Sites 8, 11, and 12) were recommended for further study and possible remedial action.
These sites will be addressed in a separate ROD. OU-3B sites include Sites 1, 7, 14, and 16.
These sites will also be addressed in a separate ROD.

Section 5
SUMMARY OF SITE CHARACTERISTICS
Interpretation of the nature and extent of contamination at Sites 4, 6, 9, 10, 13, 15,19, 20, 21, 22,
and 25 is based on the Phase I and II RI data presented in the Draft Final OU-3A and Site 25 RI
reports (BNI 1997a,b). These data include the results of shallow and deeper subsurface soils
investigations, groundwater investigations, soil gas investigations, sediment and surface-water
investigations, aerial photograph reviews, and interviews with MCAS El Toro personnel.
The Phase I RI was conducted during 1992 and 1993. The Phase II RI was conducted during
1995 and 1996. The Phase II investigation consisted of a review of data gathered previously
(e.g., interviews, aerial photograph surveys, soil gas surveys, results of previous investigations)
and additional sampling and analysis designed to fill in data gaps from the Phase I investigation
and to provide information necessary to conduct a baseline human-health risk assessment (at all
sites) and an ecological risk assessment (at Site 25).
The sections that follow provide a history of the contamination at each site, a summary of
sampling performed during the Phase I and II investigations, and tables containing site-specific
sampling results. The Phase I and II investigations showed that contamination is limited to
shallow soils at Sites 4, 6, 9, 10, 13, 15, 20, 21, and 22; and to surface water and sediment at
Site 25. Categories of compounds detected in soils at these sites include VOCs, SVOCs, total
petroleum hydrocarbons (TPH), pesticides, herbicides, PCBs, dioxins, and metals.
The site-specific tables summarize the contaminants found at each site. As discussed in
Table 1-1, most of the OU-3 sites were divided into units to facilitate the RI. Site-specific results
are also presented by unit or groups of units. Grouping of units was based on the location of the
site units relative to each other, the nature of historic activities, the nature and magnitude of the
chemical contaminants, and physiographic characteristics of the various units. TPH results are
excluded from these tables because human-health risks were based on the constituents of TPH
(e.g., benzene, toluene, ethylbenzene, xylenes, polynuclear aromatic hydrocarbons) rather than
tptal TPH because a toxicity criterion has not been developed for TPH.
A complete discussion of sampling locations and methodologies, compounds detected at each
site, and a discussion of the nature and extent of contamination appears in the Phase II Draft
Final RI reports for OU-3 A and Site 25 (BNI 1997a,b).
5.1 SITE 4
Site 4 is located in the northeast quadrant of MCAS El Toro. In August, 1983, the
contents of a 500-gallon tank (wash water and residual jet fuel) reportedly overflowed
during washing and spilled onto the ground, draining into a ditch adjacent to Ninth Street
(Jacobs Engineering 1993a). The spilled liquid reportedly contained approximately
5 gallons of ferrocene and hydrocarbon carrier solution. Ferrocene is an organic
compound used as an antiknock additive and catalyst in gasoline and jet fuel. In addition
to the ferrocene spill, Site 4 is characterized by a stained area that was the result of oily
discharge emanating from Building 658, observed over at least a 2-year period. Based

Section 5 Summary of Site Characteristics
upon the types of activities taking place at Building 658, the discharges may have
consisted of heavy oils, solvents, and fuels (Jacobs Engineering 1993a).
Twenty-one shallow-soil (0 to 10 feet below ground surface [bgs]) samples and seven
deeper subsurface-soil (greater than 10 feet bgs) samples were collected from eight soil
boring or monitoring well locations within Site 4 boundaries during the Phase I
investigation. Six soil samples (two shallow samples and four deeper subsurface
samples) were also collected from two soil boring located off-site. In addition, one
sediment sample was collected from a catch basin located within Unit 2 and groundwater
samples were taken from three Site 4 monitoring wells. A Phase II RI was not conducted
at this site because the results of the Phase I investigation were considered adequate to
characterize the nature and extent of contamination. Table 5-1 summarizes the results of
the Phase I investigation. Chemicals detected in shallow soil at Site 4 included VOCs,
SVOCs, TPH, pesticides, and metals above MCAS El Toro background levels.
5.2 SITE 6
Site 6 is located in the southeast quadrant of MCAS El Toro. From approximately 1969
to 1983, aircraft drop tanks were transported to Site 6 where their remaining fuel was
drained from the tanks. Residual JP-5 fuel in the tanks was washed out onto the concrete
apron, and the combined fuel/rinsewater ran onto the adjacent grassy area. It is estimated
that approximately 1,400 gallons of JP-5 fuel were drained from the drop tanks onto the
concrete apron and washed onto the adjacent areas. In addition to fuels, waste lubricant
oils from maintenance operations were also reportedly stored in drums and staged in the
area. It is estimated that 300 gallons of waste oil leaked from these storage drums
(Brown and Caldwell 1986).
Twenty-two shallow-soil samples, six deeper subsurface-soil samples, and one sediment
sample from a catch basin were collected at Site 6 during the Phase I investigation. In
addition, two shallow-soil samples and four deeper subsurface-soil samples were
collected from three off-site locations. Phase II soil sampling included 7 samples in
Unit 1, 6 samples in Unit 2, and 13 samples in Unit 3. All Phase II samples were taken
from the shallow-soil interval. Table 5-2 summarizes the results of the Phase I and II
investigations. Chemicals detected at Site 4 included VOCs, SVOCs, TPH, and metals.
above MCAS El Toro background levels.
5.3 SITE 9
Site 9 is located in the southwest quadrant of MCAS El Toro. Between 1965 and 1971,
the site was used as a training area for MCAS El Toro crash crew firefighters. During
training exercises, two pits were filled with water and covered with various mixtures of
residual fuels and other combustible fluids (e.g., JP-5 fuel, aviation gasoline, crankcase
oil, and other wastes). The mixtures were then ignited and extinguished by the
firefighters. Water was used as the primary means of extinguishing the fires during the

practice sessions. An estimated 123,700 gallons of waste liquids were used in the west
pit training exercises (Brown and Caldwell 1986). Although only the west pit operational
history is known, the east pit operations are believed to have been similar (Jacobs
Engineering 1993 a).
Seven shallow and ten deeper subsurface-soil samples were collected during the Phase I
investigation. All of these samples were collected within Unit 1 (the pits themselves).
Phase II sample locations were positioned throughout Units 1 and 2 (the area between and
around the pits) to characterize areas not sampled during the Phase I RI. Thirty-four soil
samples were collected within Unit 1. Twenty-eight soil samples were collected in
Unit 2. All samples were taken from the shallow-soil interval. Table 5-3 summarizes the
results of the Phase I and II investigations. Chemicals detected at Site 9 include VOCs,
SVOCs, TPH, dioxins, and metals above MCAS El Toro background levels.
5.4 SITE 10
Site 10 is located in the southwestern quadrant of MCAS El Toro. The site covers
23 acres. Prior to 1971, Site 10 was an open-ground area used for aircraft parking and
materials storage. From 1952 through 1970, an estimated 52,000 gallons of liquid
wastes, including crankcase oil, antifreeze, hydraulic and transmission fluids, motor oil,
and solvents, were sprayed over the site for dust control. The liquid wastes were
accumulated in 500-gallon, trailer-mounted tanks parked adjacent to a heavy equipment
maintenance shop at Building 1589. The tanks were fitted with spray bars and towed
over the area of Site 10, applying the liquid wastes to the open ground.
In 1971, 2 feet of topsoil was excavated and removed from the center of Site 10 and a
concrete parking apron was placed over approximately one-third of the site. The
excavated soil was transported to the land farm area northwest of Bee Canyon Wash and
eventually to the Magazine Road Landfill. A second lift of concrete was placed over the
first in 1985.
Nineteen shallow-soil samples and 11 deeper subsurface-soil samples were collected
from Units 1 and 2 during the Phase I RI. Phase II sample locations were positioned
throughout these units to characterize additional areas not sampled during the Phase I RI.

In addition, two parking lots (Units 3 and 4) were added and sampled during Phase II.
Phase II sampling consisted of 25 shallow-soil samples in Unit 1, 30 shallow-soil samples
in Unit 2; 36 shallow-soil samples in Unit 3; and 7 shallow-soil samples in Unit 4.
Table 5-4 summarizes the results of the Phase I and Phase II investigations. Chemicals
detected at Site 10 included VOCs, SVOCs, and metals above MCAS El Toro
background levels.
5.5 SITE 13
Site 13 is located in the northwest quadrant of MCAS El Toro and encompasses about
three quarters of an acre. The site is bounded on the north by former Tank Farm No. 2.
Trucks were driven to the area southeast of the tank farm for oil changes, and crankcase
oil was frequently drained onto the ground. It is estimated that from 1977 to 1983,

approximately 7,000 gallons of waste oil were drained onto the ground. The oily soil was
subsequently removed. No visible evidence of the oily soil remains.
During the Phase I investigation, 21 shallow-soil samples and 10 deeper subsurface-soil
samples were collected within the Site 13 boundaries. Six soil samples were also
collected from three off-site boring locations. A Phase II RI was not conducted at this
site because the results of the Phase I investigation were considered adequate to
characterize the nature and extent of contamination. Table 5-5 summarizes the results of
the Phase I RI. Chemicals detected at Site 13 included VOCs, SVOCs, pesticides, and
metals above MCAS El Toro background levels.
5.6 SITE 15
Site 15 is part of a fenced storage yard located in the northwest quadrant of MCAS
El Toro. Approximately half of the site is covered by a concrete pad and metal aircraft
matting. Historically, the storage yard was used for storage and maintenance of military
vehicles and equipment, including cranes, tractors, front-end loaders, bulldozers, power
generators, and refrigeration equipment. From 1979 to 1984, two 500-gallon aboveground
storage tanks containing diesel fuel were located near the entrance gate to Site 15.
During this time period, an estimated 500 gallons of diesel fuel spilled onto the bare
ground from the fueling nozzles and hoses. The tanks were removed in 1984 (Jacobs
Engineering 1993a). .
Ongoing operations at Site 15 include equipment maintenance and cleaning on the
concrete pad as well as equipment storage in adjacent areas. Wastes generated from on-
site operations include waste oil, waste motor fuel, empty paint cans, and paint thinner.
Past site operations generated approximately three 55-gallon drums of waste material per
month. Phase II RI activities were initiated to investigate the potential release of
chemical wastes from washdown of the concrete pad and disposal of waste liquids in the
area behind Building 31 (BNI 1995).

The Phase I RI soil sampling activities at Site 15 focused exclusively on the locations of
the former aboveground diesel fuel tanks (Unit 1). This area was eliminated from
Phase II RI activities because of a CERCLA petroleum exclusion. The Phase II RI
consisted of 34 shallow-soil samples collected behind Building 31 and along a ditch
which collects drainage from the concrete pad (Unit 2). Table 5-6 summarizes the results
of the Phase II RI. Chemicals detected at Site 15 included SVOCs, TPH, pesticides,
PCBs, and metals about MCAS El Toro background levels.
5.7 SITE 19
Site 19 is located in the southeast quadrant of MCAS El Toro. Between 1964 and 1987,
Site 19 was operated as a fuel-storage and -dispensing area. JP-5 fuel contained in six
20,000-gallon aboveground fuel bladders was piped to aircraft refueling stations along the
edge of the concrete apron. Minor spills and leaks occurred during the operational period
of the facility. An estimated 20,000 gallons of JP-5 fuel were also released after a
bladder rupture (Jacobs Engineering 1993a). An investigation after the rupture found
elevated levels of petroleum hydrocarbons in soil beneath the ruptured bladder. The fuel
bladders were removed in 1986, and the soil was excavated to a maximum depth of about
15 feet bgs in a 30-foot-square area directly beneath the location of the bladder rupture.
The 15-foot-deep excavation was partially backfilled to a depth of approximately 11 feet

Section 5 Summary of Site Characteristics
in 1993. The backfill material consisted of soil containing PCBs, which had been
removed from Site 8 during a paving operation. In 1996, the remaining excavation was
backfilled to surrounding grade with clean fill material as part of the removal action
conducted to reduce human-health risk. An additional 290- by 65-foot area beneath the
locations of the other bladders was also excavated in 1986 to a depth of about 2.5 feet.
This excavated area has not been backfilled and is partly vegetated (Jacobs Engineering
1993a). The fuel bladders, which were removed in 1986, were replaced by a pump
station and UST complex adjacent to the east side of the site.
The Phase I RI addressed three subareas within Site 19: the Northwest Stained Area
(Unit 1), the Excavated Area (Unit 2), and the Stained Area Around Excavation (Unit 3).
A section of the current pump station and UST complex, designated Unit 4, was added to
the scope of the Phase II RI to address contamination reported during the RFA.
However, subsequent to this addition, Units 1 and 4 were removed from the IRP by the
BCT based on a CERCLA petroleum exclusion and are not addressed in this ROD.
Eighteen shallow-soil samples and 23 deeper subsurface-soil samples were collected
during the Phase I investigation. Phase II sample locations were positioned to further
characterize the extent of chemicals reported during the Phase I RI. Twenty shallow-soil
samples were collected during the Phase II RI throughout Units 2 and 3. Table 5-7
summarizes the results of the Phase I and II RIs. Chemicals detected at Site 19 included
VOCs, SVOCs, TPH, and metals above MCAS El Toro background levels.
5.8 SITE 20
Site 20 is located in the northwest quadrant of MCAS El Toro. Since 1967, the site has
been used as an auto shop for military personnel to service and repair their privately
owned vehicles. Prior to 1986, kerosene reportedly was used to wash down the paved
courtyard area. The wash runoff drained into a catch basin located in the entry driveway
and finally drained into the oil/water separators. Since 1976, a biodegradable soap has
been used in place of the kerosene. *
Site 20 is divided into four units: the East Drainage Ditch (Unit 1), the South Drainage
Ditch (Unit 2), the Stained Area (Unit 3), and the Courtyard and Front Slope (Unit 4)
(Figure 1-2). Units 2 and 3 were removed from the Phase II RI based on the petroleum
exclusion under CERCLA.
Sixteen shallow-soil samples and one sediment sample were collected at Site 20 during
the Phase I investigation. Two additional shallow-soil samples were collected from one
off-site location. Phase II sample locations were positioned to further characterize the
extent of contaminants reported during the Phase I RI. Sixteen shallow-soil samples were
collected during the Phase II investigation. Table 5-8 summarizes the results of the
Phase I and II RIs. Chemicals detected at Site 20 included VOCs, TPH, pesticides,
PCBs, and metals above MCAS El Toro background levels.

5.9 SITE 21
Site 21 occupies about one-third acre in the southwest quadrant of MCAS El Toro. The
site is part of the supply distribution center for MCAS El Toro and other Marine facilities
and has been used for the storage of drummed materials since approximately 1946. All
drummed materials stored at the site were removed in 1995. No leaks or spills have been
documented at the site; however, the site was investigated because contaminants may
have leaked from drums during operation of the storage area.
Nine shallow-soil samples, seven deeper subsurface-soil samples, and one sediment
sample were collected from Site 21 during the Phase I investigation. Two shallow-soil
samples and four deeper subsurface-soil samples were also collected from off-site
borings. Phase II sample locations were positioned to characterize additional areas not
sampled during Phase I. Ten shallow-soil samples were collected during the Phase II RI.
Table 5-9 summarizes the results of the investigations. Chemicals detected at Site 21
included VOCs, SVOCs, TPH, pesticides, herbicides, PCBs, and metals above MCAS
El Toro background levels.
5.10 SITE 22
Site 22 is located in the southwest quadrant of MCAS El Toro. The site is a former
aircraft fuel storage and dispensing facility. Fuel storage was first observed in aerial
photographs dating from approximately'1952 and historically occurred in two areas: an
eastern fuel-dispensing area and a western fuel-dispensing area. Heavy staining was
observed at both locations (SAIC 1993) and the western fueling area has a documented
history of spills.
Seven surface-soil samples and 22 subsurface-soil samples were collected during the
Phase I investigation. An additional nine shallow-soil samples were taken during the
Phase II RI. Sampling results are summarized in Table 5-10. Chemicals detected at

Site 22 included VOCs, SVOCs, TPH, pesticides, and metals above MCAS El Toro
background levels.
5.11 SITE 25
Site 25 consists of four main drainage channels that flow through or adjacent to the
Station. The site was included in the IRP because it was not known whether the major
drainages were acting as a source of regional VOC contamination in the Irvine
Groundwater Subbasin. Investigation data presented in the draft final Phase II RI for
Site 24 demonstrated that Site 24, not Site 25, is responsible for the observed VOC
groundwater contamination.
Phase I sampling consisted of 36 surface water samples, 29 sediment samples, and 60 soil
samples. Soil gas samples were also collected at depths between 5 and 30 feet bgs at
27 locations near Agua Chinon and Bee Canyon Washes. Phase II samples were taken in
the same media to confirm and supplement Phase I results.
• Thirteen surface water samples were taken from all four drainages. Both
upstream and downstream locations were sampled in order to evaluate the
impact of runoff from the Station.

Section 5 Summary of Site Characteristics
• Sediment samples were collected at two locations along Marshbum Channel.
• Thirty-four soil samples were collected from four soil borings. Three of the
four borings were located adjacent to the downstream end of Agua Chinon
Wash. The fourth boring was located near the downstream end of Bee Canyon
Wash.
• Ten soil gas samples were taken from three locations along Agua Chinon Wash
at depths between 47 and 90 feet bgs. Soil gas samples were used to assess
potential contribution of the drainages to the regional VOC contamination.
Tables 5-11 and 5-12 summarize the results of surface-water sampling at San Diego
Creek and sediment sampling at Agua Chinon Wash, Bee Canyon Wash, Borrego
Canyon Wash, and Marshburn Channel, respectively. These data were used for the
human-health'and ecological risk assessments as discussed in Section 6. Results of soil
sampling are not presented because, as discussed in Section 6 of this report, there is no
complete exposure pathway to chemicals in soil below 2 feet at Site 25.
Soil and soil gas analytical results were evaluated to characterize the potential
contribution of the Site 25 drainages to the regional VOC groundwater contamination.
Of the 94 soil samples collected during the Phase I and Phase II RIs, none had reportable
concentrations of TCE or PCE. Chemicals detected in soil gas included TCE, PCE,
cis-l,2-dichloroethene, trans-1,2-dichloroethene, toluene, xylenes, and total volatile
hydrocarbons. TCE was reported in 3 of 68 soil gas samples at a maximum concentration
of 53.1 micrograms per liter (ug/L). PCE was reported in 1 of 68 soil gas samples at a
maximum concentration of 1.6 ng/L. Based on these findings and the high
concentrations of TCE and PCE in soil and soil gas at Site 24, it was concluded that Site
24, not Site 25, is the source of the regional groundwater contamination.

Section 6
SUMMARY OF SITE RISKS
A human-health risk assessment (HHRA) was conducted for Sites 4, 6, 9, 10, 13, 15, 19, 20,21,
22, and 25 using data collected during the Phase I and Phase II RIs. The human health
evaluation methodology is provided in Section 6 of the draft final RI reports for these sites (BNI
1997a,b). An ecological risk assessment was also conducted for Site 25. The methodology is
provided in Section 7 of the draft final RI report for Site 25 (BNI 1997b). An ecological risk
assessment was not performed for the OU-3A sites because a habitat assessment performed for
these sites in May 1995 indicated an absence of significant plant and wildlife habitat.
6.1 HUMAN-HEALTH RISK ASSESSMENT
During the RI, the Navy considered the potential human-health risks associated with the
OU-3A sites and Site 25. The HHRA was based on exposure to soils at Sites 4, 6, 9, 10,
13, 15, 19, 20, 21, and 22 and to sediment and surface water at Site 25. Exposure to
groundwater was not included because the RI indicated that contamination is present only
in the shallow-soil interval and does not extend to groundwater beneath any of the sites.
The HHRA was performed using residential and industrial scenarios for the OU-3A sites
and residential and recreational scenarios for Site 25. Evaluation of the residential
scenario at the OU-3A sites is considered conservative because the primary proposed
reuses of the OU-3A sites addressed in this ROD are industrial and aviation-related
(Table 1-1) and risks calculated for this type of scenario are usually less than risks
calculated under the residential scenario. Evaluation of the residential scenario at Site 25
is conservative because this site consists of drainage channels and culverts that do not
provide a suitable location for residences. Exposure of the industrial worker was
considered to be limited to contaminants in surface soils (0 to 2 feet bgs), whereas it was
considered that the resident could be exposed to contaminants present from 0 to 10 feet
bgs (shallow soils). For Site 25, the recreational scenario is considered conservative
because it was assumed that a child would play in the water at San Diego Creek (which
receives runoff from the Site 25 drainages) 2 hours a day, 350 days a year for 7 years.
Actual exposure is likely to be much less.
Possible exposure pathways examined for the chemicals at the surface and in shallow soil
at the OU-3A sites were ingestion of soil, inhalation of vapors and dust, and direct
contact with the skin. Exposure conditions used in the estimation of risk were chosen to
represent what is known as "reasonable maximum exposure" (RME). Use of these
exposure conditions tends to overestimate risk. This effort to overestimate risk is
deliberate; it provides risk managers a margin of safety when making cleanup decisions.
The combination of the intake variables, expressing the exposure conditions for each
receptor at each site, results in a chronic daily dose. The dose is an estimate of exposure
for each pathway.
Risks were calculated by integrating the chronic daily dose with toxicity factors.
Toxicity factors are numbers developed by U.S. EPA for each COPC that indicate the
toxicity of the chemicals. The toxicity factor for carcinogenic effects is called a cancer

Section 6 Summary of Site Risks
slope factor (CSF) and the toxicity factor for noncarcinogenic effects is called a reference
dose (RfD). Chemicals that show a potential for both carcinogenic and noncarcinogenic
health effects are assigned both slope factors and reference doses. In addition to the
U.S. EPA derived CSFs, Cal-EPA has developed CSFs for a group of carcinogens.
Following DON policy, both U.S. EPA and Cal-EPA slope factors were used in the
estimation of the risk from those chemicals when present. CSFs and RfDs are derived
from the results of human epidemiological studies or chronic animal bioassays to which
animal-to-human extrapolation and uncertainty factors have been applied. These
uncertainty factors help ensure that the toxicity values will not underestimate the
potential for carcinogenic and adverse noncarcinogenic effects to occur.
Excess lifetime cancer risks are probabilities that are generally expressed in scientific
notation (e.g., 1 x 10"* or 1E-6). An excess lifetime cancer risk of 1 x 10"6 indicates that,
as a plausible upper bound, an individual has a one in a million chance of developing
cancer as a result of site-related exposure to a carcinogen over a 70-year lifetime under
the specific exposure conditions at a site. Guidelines for managing cancer risks are
promulgated in the NCP (40 CFR 300. 430 (e)(2)(i)(A)(2)). According to these
regulations, excess cancer risks in the range of between 10~* and 10"4 or less are
considered generally acceptable.
Potential noncarcinogenic effects of a single contaminant in a single medium are
expressed as hazard quotients (HQs). By adding the HQs for all contaminants within a
medium or across all media to which a given population may reasonably be exposed, the
hazard index (HI) can be generated. The HI provides a useful reference point for gauging
the potential significance of multiple contaminant exposures within a single medium or
across media. The U.S. EPA has also established guidelines for noncancer risks. Using
these guidelines, an HI of less than 1 is generally considered protective of human health.
If the HI is greater than 1, an assessment of the chemicals is performed to determine
whether the HI represents an unacceptable noncarcinogenic human-health risk.
At Site 25, the Phase I RI results showed that under the recreational scenario the cumulative
excess cancer risk from sediment was less than 1 x 10"6 and the noncarcinogenic His were
less than 1.0 (Jacobs Engineering 1993b). A qualitative HHRA was performed with the
Phase II sediment data at the drainages to strengthen the Phase I RI results. Phase II
sediment data were compared to the Phase I data and to background values established in
the Final Technical Memorandum on Background and Reference Levels (BNI1996b). This
comparison showed that among the Phase II downstream sediment sample results, only
copper (11.6 milligrams per kilogram [mg/kg]) exceeded the background level of
10.5 mg/kg. The Phase II result for copper was less than the Phase I concentration of
12.4 mg/kg. These data corroborate the Phase I results and suggest that the additional
sample results would not increase the cumulative cancer risk to a level greater than 1 x 10"6,
and the HI would remain less than 1.

Section 6 Summary of Site Risks
An additional human-health risk assessment was performed for Site 25 based on dermal
contact with chemicals reported in surface water at San Diego Creek. As shown on
Figure 1-2, this creek receives runoff from the OU-2A major drainages. The risk
assessment was based on a recreational scenario. The results of the risk assessment are
shown in Table 6-1 and indicate that, if no remediation occurred, carcinogenic risks due
to surface water in San Diego Creek are in the range of 10"6 to 10~7.

' the majority of the hazard index is due to aluminum (92 percent)
Surface water from San Diego Creek exhibited a chronic HI slightly greater than 1 (1.2).
This HI was primarily associated with dermal exposure to aluminum in the surface-water
medium and overestimates actual risk because the acid which is used in preservation of
surface-water samples causes the suspended aluminum silicate minerals present in the
turbulent-flow samples to be dissolved in the water. Normally, aluminum present as
aluminum silicate is not available as elemental aluminum for dermal exposure.
The results of the risk assessment for exposure to soils at the OU-3 A no action sites are
summarized in Table 6-2. The table identifies the total cancer and/or noncancer risk for
each receptor. In addition, it identifies, the chemicals contributing the majority of the
cancer risk and HI. Cancer risks are based on U.S. EPA and Cal-EPA CSFs, as
appropriate. Risks to an excavation worker at the OU-3A sites were qualitatively
assessed. Cancer risk to these individuals was estimated to be at least seven times less
than the risk to a resident adult and ten times less than the risk to a resident child.
Therefore, risks to the excavation worker are considerably less than the risks to the
resident (Table 6-2).
The results of the human health risk assessment indicate that, if no remediation occurred,
risks at Sites 4, 6, 9, 10, 13, 15, 19, 20, and 22 would fall below 1 x 10"4 for both the
residential and industrial scenarios. The risks to the resident due to the catch basin at

Section 6 Summary of Site Risks
Site 21 are slightly higher than 1 x 10"4 based on samples of the sediment. However, the
sediment in the catch basin was removed subsequent to the completion of the RI for
OU-3A and these risks no longer exist.
Table 6-2 shows that the His for all OU-3A sites are less than 1 under the industrial
scenario. Although the His exceed 1 for some sites under the residential scenario, these
exceedances were analyzed further and found to be primarily associated with manganese.
Manganese is naturally occurring at the Station and is not believed to be related to site
activities. It was determined that manganese levels at the sites fall within the naturally
occurring range, or background, for this metal. Therefore, manganese concentrations
reflect the natural variation in the concentration of this metal both on and off the Station,
and not contamination resulting from past activities at the Station.
The RIs concluded that human-health risks posed by COPCs in soils (OU-3A no action
sites) and sediment and surface water (Site 25) are within the risk range considered
acceptable by the U.S. EPA. This is the basis of the no action recommendation for these
sites.
6.2 ECOLOGICAL RISK ASSESSMENT
The only site for which an ecological risk assessment was required was Site 25. The
purpose of the risk assessment was to assess current and potential hazards to ecological
receptors posed by sediment in the drainages. Exposure to surface water at the drainages
was not evaluated because flow is sporadic and lasts only a few hours or days following a
heavy rainfall.
The potential for mobilization of chemicals of potential ecological concern (COPECs) in
the food chain was evaluated by modeling plant, invertebrate, deer mouse, California
quail, American robin, coyote, and red-tailed hawk. The primary exposure pathway was
ingestion. Deer mouse, American robin, and California quail are assumed to ingest
COPECs from sediment, invertebrates, and plants. The coyote is assumed to ingest
COPECs from sediment, macroinvertebrates, plants, deer mice, and quail. The red-tailed
hawk is assumed to ingest COPECs from sediment, deer mice, and quail.
Ecological receptors may also be exposed to COPECs in sediment via dermal contact
(e.g., while burrowing). However, because of the paucity of data regarding dermal
exposure for wildlife organisms, this pathway was not evaluated in the risk assessment.
Receptors may also be exposed to COPECs through inhalation of organic vapors and
fugitive dust. Inhalation of organic vapors was assumed to be limited to those receptors
living at or below the ground surface. Intake through inhalation of fugitive dust was
considered minimal relative to other pathways and was not considered in the risk
assessment.
Like human-health hazards, ecological hazards are also characterized using an HQ
approach. The effects of a single contaminant in a single medium is expressed as the HQ.
By adding HQs for all contaminants within a medium or across all media to which a
given population may reasonably be exposed, the HI is developed. His less than 1 for

each mechanism of action or target organ are reasonably good indicators that adverse
effects are unlikely. If an HI is greater than 1, the hazards of exposure through individual
pathways are generally examined in greater detail to evaluate the primary sources of risk.
The HQs for the deer mouse, American robin, California quail, coyote, and red-tailed
hawk are presented in Table 6-3. Chemical levels at Borrego Canyon Wash and Agua
Chinon Wash are at or below background levels. Ecological His at Bee Canyon Wash are
estimated at less than 1.0. At Marshburn Channel, with the exception of the American
robin and red-tailed hawk, the His were generally less than or slightly greater than 1.

At Marshburn Channel, the His of 237 for the American robin and 129 for the red-tailed
hawk were associated almost exclusively with exposures to pesticides, 4,4'-DDD,
4,4'-DDE, and 4,4'-DDT, and were less than the His associated with exposures to
regional background levels of these chemicals. The concentrations of these pesticides in
this channel are within the background range of pesticides in the vicinity of MCAS El
Toro. The channel is also shallow and concrete-lined with little vegetation resulting in a
low quality habitat for wildlife.
The Phase II RI concluded that historical agricultural practices and natural geologic
conditions can account for the chemicals reported in sediment samples in the Site 25
drainages. Minor concentrations of oil can be attributed to runoff from parking areas and

roadways. These chemical characteristics appear to be similar to other drainages in the
area. These data suggest that activities at MCAS El Toro do not contribute a significant
adverse effect on sediment beyond what is expected given the geologic character of the
watershed, the historical agricultural practices, and fairly heavy motor-vehicle traffic.
Based on the results of the ecological risk assessment at Site 25, the Marine Corps has
concluded that the risk to the wildlife in all four drainages is not significant and no
cleanup is proposed.

Section 7
DESCRIPTION OF NO ACTION ALTERNATIVE
Based on the Phase I and Phase II RIs and the baseline HHRA, Sites 4, 6, 9, 10, 13, 15, 19, 20,
21, 22, and 25 do not pose an unacceptable risk to human health or the environment.
Accordingly, no remedial action is appropriate for the RI sites. DON will not conduct
monitoring or periodic reviews of the sites. The DTSC, RWQCB, and U.S. EPA agree with this
determination. The DON's selection of no action for these sites reflects the determination that
the overall condition of the sites is protective of human health and the environment.
Section 121 (d) of CERCLA states that remedial actions at CERCLA sites must, upon
completion, attain any federal (or state if more stringent) environmental standards, requirements,
criteria, or limitations that are determined to be applicable or relevant and appropriate
requirements (ARARs). ARARs do not apply unless remedial action is being taken at a site and
are therefore not applicable to the no action sites addressed in this ROD.
Although no deed restrictions are required because of chemicals present in soils at the no action
sites, shallow groundwater underlying Sites 9, 10, 13, 15, 21, 22, and portions of Site 25 is
contaminated by TCE and PCE. Remedial investigations have shown that the contamination
does not originate from these sites but from Site 24, the VOC source area. Use restrictions for
several sites (including Site 24 and the no action sites listed above) prohibiting drilling of wells
and/or extraction of groundwater and allowing access for groundwater monitoring and
maintenance of equipment associated with groundwater remediation will be addressed in the
Proposed Plan(s) and Record(s) of Decision for OU-1 and 2A regarding groundwater.

DOCUMENTATION OF SIGNIFICANT CHANGES
The Proposed Plan for Sites 4, 6, 9, 10, 13, 15, 19, 20, 21, 22, and 25 was released for public
comment in May 1997. The Proposed Plan identified no action as the appropriate response for
these sites. DON reviewed all written and verbal comments submitted during the comment
period. Upon review of these comments, it was determined that no significant changes to the
response, as it was originally identified in the Proposed Plan, were necessary.

The Marine Corps Air Station (MCAS) El Toro Master Development
Program staff have completed a review of the proposed plan for
environmental restoration at the Installation Restoration Program (IRP)
Sites 4,6,9,10,13, 15, 19,20,21,22, and 25 (Operable Unit [OU]-3A
"No Further Action" sites) at MCAS El Toro in light of the County of
Orange's adopted community reuse plan. This review was done in
consideration of Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA) § I20(h)(3) and
Section 330 of the 1993 National Defense Authorization Act, which
provide that the Marine Corps is, and will remain responsible for any
contamination on the site at the time of transfer of these parcels, and that
the Marine Corps will indemnify and defend the County and the
County's tenants from any liability and economic loss that results from
any preexisting contamination, or any contamination and economic loss
that results from any preexisting contamination, or any contamination
which is caused or contributed to by the Marine Corps or its operations at
these sites. The Local Redevelopment Authority (LRA) submits the
following comments:
1. At the 06 August 1997 Restoration Advisory Board meeting, Andy
Piszkin, Remedial Project Manager, Naval Facilities Engineering
Command, Southwest Division, implied that while the referenced
sites would not have any restrictions as to their reuse, some of these
sites may overlie contaminated groundwater and that it was possible
that these sites might be constrained from utilizing any underlying
groundwater.
As you know, it is generally the policy of the United States
Environmental Protection Agency (U. S. EPA) and California
Environmental Protection Agency (Cal-EPA) to require disclosure
of any institutional controls or land-use restrictions imposed as part
of any proposed plan. While the LRA recognizes the need to
Shallow groundwater beneath Sites 9, 10, 13, 15, 21,22, and portions of
Site 25 is contaminated by trichloroethene (TCE) and tetrachloroethene
(PCE). Remedial investigations have shown that the contamination does
not originate from these sites but from Site 24, the volatile organic
compound (VOC) source area. The nature and extent of contamination
at Site 24 is discussed in the Remedial Investigation (RI) report for that
site. The RI report is available in the Administrative Record at MCAS El
Toro and at the information repository located at the Heritage Park
Regional Library in Irvine, California.
Remediation of groundwater and restrictions on drilling and use of
groundwater will be addressed in the Proposed Plan for Site 24
Groundwater. This plan is currently scheduled to be issued for public
review in March 1998. These restrictions were not addressed in the
Proposed Plan for the No Action sites because the groundwater
contamination is not related to Marine Corps activities that occurred at
these sites. However, a statement will be added to the No Action Record
of Decision (ROD) to clarify that restrictions may be placed on some of
the No Action sites because of groundwater contamination that originates
elsewhere on Station.

limit use of potentially contaminated groundwater under these
sites, the LRA needs to know, as soon as possible, the nature,
extent, and characteristics of any and all restrictions associated
with these No Further Action sites. The final plan for
environmental restoration at these sites and future proposed plans
for other sites must describe any and all possible land-use
restrictions.
IB
2. During redevelopment of the base, many of these sites may
require some excavation and the possible export of soil. It is the
LRA's understanding that there is no limitation on the LRA's
ability to excavate and export soil at these sites. We would
appreciate your confirmation of our understanding.
The Local Redevelopment Agency's (LRA's) understanding is correct.
The No Action sites will have no restrictions that would limit the LRA's
ability to excavate and export soil at these sites.
1C
3. The community's ability to reuse these sites will depend upon the
Marine Corps development of an acceptable response contingency
plan. While the LRA recognizes that these response contingency
plans are generally not prepared until after approval of the ROD,
the LRA requests an outline of the parameters of a response
contingency plan prior to the completion of the ROD.
The Marine Corps does not plan to develop a response contingency plan
for the No Action sites because the remedial investigation and risk
assessments show that the sites do not present a risk to human health or the
environment and no action is required.
ID
4. Some of these sites show the presence of manganese and arsenic
in the soils. The Proposed Plan indicates that the levels of these
metals are "within the background range of these metals in the
vicinity of MCAS El Tore." If further studies determine that these
metals do in fact limit the reuse of this property or pose a potential
risk to the community, the Marine Corps must commit to
remediate these metals.
Metals such as manganese and arsenic occur naturally in soil and rock.
The concentration of these metals varies from place to place depending on
geologic factors. The Department of the Navy (DON) is not responsible
for the presence of, or remediation of naturally occurring background
levels of inorganics.
The DON is responsible for remediation of releases that occurred because
•of Marine Corps activities. This responsibility does not end when the
property is transferred. According to the Comprehensive Environmental
Response, Compensation, and Liability Act (CERCLA), Section 120(h),
the DON retains responsibility for remedial action found to be necessary
after property is transferred provided the need for remedial action is
attributable to Marine Corps activities. If further studies were to show that
metals at a given site exceed background as the result of releases due to
Marine Corps activities and that these exceedances present a risk to human

health, the DON would be required to conduct remedial action as necessary.
This responsibility is clarified in a letter from the U.S. EPA to Joseph Joyce,
dated 05 June 1997. The letter is available in the Administrative Record at
MCAS El Toro.
Comments by: Larry Agran on behalf of Project '99, In a letter dated 12 August 1997
Project '99 has prepared the following comments on the Proposed
Plan for No Further Action at 11 Installation Restoration Program
(IRP) sites at MCAS El Toro (Sites 4,6,9, 10, 13, 15, 19, 20,21, 22,
and 25).
The Human Health Risk Assessment conducted for these sites has
concluded that the potential cancer risks for these sites range from 2
to 4 additional cases per 100,000 exposed population (with the
exception of Site 15, which is less). We understand that the No
Further Action proposal is based in part on the U.S. EPA terminology
of "generally acceptable risk" at these calculated risk levels.
It is our position that the stricter U.S. £PA risk range of "acceptable
risk" (less than 1 additional cancer case per 1 million exposed
population) should be applied to the No Further Action decision to
protect the health of future occupants and workers at these sites.
No Action decisions at MCAS El Toro conform to regulatory requirements
established in the CERCLA and in the National Oil and Hazardous
Substances Pollution Contingency Plan (NCP). According to NCP (Section
300.430(e)(2)(iX2), excess cancer risks in the range of 1 in 100,000 to 1 in
1,000,000 are considered to be generally acceptable.
The risk assessments performed for the No Action sites during the Phase II
Remedial Investigation (RI) were very conservative. The assessments
performed for the OU-3A sites (Sites 4,6,9, 10, 13, 15, 19,20,21, and 22)
assumed that each site could be used as a residence or as a commercial
business place. The assessments performed for Site 25 assumed that the
drainages could be used for residential or recreational purposes. The resident
was assumed to live in the house on-site from birth to age 30 and to be
exposed to contaminants in the soil through ingestion, dermal exposure, and
inhalation. A soil ingestion rate of 100 milligrams a day was assumed for an
adult and 200 milligrams a day for a child, 350 days a year. For dermal
exposure, 25 percent of the resident's skin was assumed to be in contact
with soil for 100 days a year. The resident was also assumed to inhale soil
particulates and gases 24 hours a day, 350 days a year. Risk assessments are
also inherently conservative because the concentration of contaminants used
to calculate risk is not an average concentration, but either the highest
detected concentration or the 95th percentile upper confidence limit of the
mean. It is also assumed that this concentration remains constant for the
entire period over which the risk is calculated (e.g., 30 years), when in fact
many chemicals degrade over time. Uncertainties in the risk assessment are
discussed in more detail in the RI reports for the No Action sites and for
Site 25. These reports are available in the Administrative Record at MCAS
El Toro.

Even under these conservative assumptions, the highest risk at any site was
4 additional chances of contracting cancer in a population of 100,000. The
human-health risk assessment performed for Site 25 estimated potential
cancer risks for residents exposed to sediment over 30 years to be less than 1
additional case in 1,000,000. It is also possible that the risk may not
increase at all, because of the conservative nature of the assumptions.
Considering regulatory requirements and the conservative nature of the risk
assessment process, the DON, U.S. EPA, Department of Toxic Substances
Control (DTSC), and the Regional Water Quality Control Board (RWQCB)
concur that the excess cancer risk at all of these sites is acceptable and no
action is required.
Comments by: Gail Reavls, Mission Vlejo resident, In a letter dated 10 August 1997
I have some questions for the public record regarding the "No Further
Action at Eleven Sites", specifically directed at those eleven sites.
Are there any buildings or structures of any kind on any of these
eleven sites? Do any of these buildings/structures contain any
asbestos (friable or otherwise), lead-based paint or any other now
environmentally prohibited substances? If the answer is yes to any of
these questions, what (if any) are the Navy's plans for cleanup/
remediation? If these buildings are left on the property with
stipulations regarding hazardous substances, who will be financially
and physically responsible for their cleanup/removal at some later
date should these buildings require tearing down, moving, etc.?
Nowhere in the June 1997 Restoration Advisory Board (RAB)
newsletter did it make any mention whatsoever of any structures or
plans for remediation. It would lead one to assume that either there
are no structures on the sites, or that their remediation would be
addressed at future Public Comment Periods.
Buildings containing asbestos and lead-based paint present on Station are
addressed under the Base Realignment and Closure (BRAC) program, not
under the Installation Restoration Program. The BRAC program is
described in the BRAC Cleanup Plan, issued in March 1997.
According to this plan, the Station is required to document all available
information concerning asbestos-containing materials (ACM) prior to
property transfer. Identified ACM will be remediated only if it is not in
compliance with applicable laws and regulations or if it poses a threat to
human health at the time of property transfer.
Transfer of federal property for residential use will be conducted in
accordance with the Residential Lead-Based Paint Hazard Reduction Act of
1992 (Title X of Public Law 102-550). Under this provision, housing
constructed before 1978 must be inspected for lead-based paint and lead-
based paint hazards. Results of the inspection must be provided to the
prospective transferee of the property. Abatement is required for housing
constructed prior to I960 and a description of the abatement activities must
be provided to the prospective transferee. Abatement is not required for

housing constructed between 1960 and 1978. However, the prospective
transferee must be provided with a lead-hazard information pamphlet, and
the contract for sale or lease must include a lead-warning statement.
The reason that remediation of asbestos and lead-based paint is not
addressed in the Proposed Plans for the IRP sites is that asbestos and paint
are not considered releases and are not addressed under the Comprehensive
Environmental Response, Compensation, and Liability Act (CERCLA) or
the IRP. Remediation of these substances is handled under the BRAC
program as described above.
Comments by: Fred and Cheryl Heinecko, Irvine residents, in a letter dated 25 July 1997
I am writing to express my concern about the 11 sites on the El Toro
Marine Base that you are proposing to clean up.
El Toro Marine Corps has been designated as a Superfund site.
Therefore, it is the government's responsibility and duty to clean all
of the base before it is turned over for civilian use in 1999. If local
government officials are telling you it is not necessary to clean all the
sites on the base because it is going to be turned into an airport, let me
assure you that this is not necessarily the case. Many other alternative
uses are being considered that would require all contamination to be
removed.
In addition, there is more involved than surface contamination.
Unless all sites are cleaned, there is the continued threat of
contamination to the groundwater of the surrounding communities.
Therefore, I urge you to change your recommendations and clean up
all contaminated sites at El Toro MCAS.
MCAS El Toro is a National Priorities List site. No moneys from the
federal Superfund are used at MCAS El Toro.
The 11 No Action sites were investigated thoroughly to determine if there
were any chemicals present in the soil that could present a risk to human
health or the environment either directly through ingestion, dermal contact,
or inhalation, or indirectly by migrating or traveling to groundwater. The
investigations of the sites included more than surface samples. Each site
was sampled down to 10 feet below ground surface (bgs) or farther. This
investigation showed that the chemicals potentially released at the 11 No
Further Action sites do not present a threat to groundwater. Risk
assessments were performed for the sites assuming that houses would be
built on the sites and the residents would live in the houses for 30 years.
Residents were assumed to be exposed to soil down to 10 feet bgs at the
Operable Unit (OU)-3A sites and to sediment in the washes at Site 25.
Exposure was assumed to occur through ingestion, inhalation, and dermal
contact with soils and sediment. These risk assessments showed that the
chemicals present at the No Action sites do not present an unacceptable risk
to human health under a residential reuse scenario.
The decision whether remedial action is required at a particular site is
independent of future use of the Station. Each of the 11 No Action sites was
evaluated and found safe to use for residential purposes.

Received your last memo brochure concerning "No Further Action at
Eleven Sites." I heartily agree with this decision. I plan to attend the
Public Meeting on July 31 at 4:30 p.m. in the Irvine City Hall.
As far as I can see, the effects of solvents on the sites advocated are
minor. A general cleanup will do the trick. The general risk factor has
been overplayed. The conclusions of your article on "Human Health and
Ecological Risk Assessments" are valid!
Too much concern has overplayed all issues. Let us move forward and
complete the job.
Thank you for your support. For clarification, the remedial
investigations and risk assessments performed for the No Action sites
show that no remediation, not even a general cleanup, is required. These
sites are acceptable for use as they currently exist.
Comments by: Gregg James, Laguna Nlguel resident, In a letter faxed 19 August 1997
Do the right thing.
Am I mistaken or isn't the base on the Superfund list due to the extent of
toxic contamination? I find it very hard to believe that now that the
Marines will be leaving that the problems continue to be minimized. An
example of this is the statement that one of the sites is no more than a 5-
galion fuel spill. Things like this would hardly qualify the base to be
number 24 on the list of the 50 top sites in the country to be cleaned up.
I was glad to see that it was recommended that the site that is
contaminating groundwater under the base and Irvine's Woodbridge area
will be cleaned up. If it won't need to be cleaned up the remaining 13
[sites] must pose significant health risks to put the base on the Superfund
list. I hope and pray that the Marines will do the needed cleanup and not
just contain the problems they leave. We must be able to develop this
land to any use and have it be safe for homes to industrial use. I just
hope we don't see the same type of studies that were done at Miramar
where the Navy admitted that they lied on environmental studies there
and were given political instructions as to the desired outcomes.
The United States Environmental Protection Agency (U.S. EPA)
recommended adding MCAS El Toro to the National Priorities List
because of the presence of volatile organic compound (VOC)
contamination at the Station boundary and the detection of VOCs in
agricultural wells west of the Station. This VOC contamination has been
investigated and found to have its source at Site 24, the VOC Source
Area. Soil and groundwater at Site 24 are addressed in separate Records
of Decision (RODs).
The sites that are addressed in this ROD for the No Action Sites have
also been investigated thoroughly. Soil samples were taken at all sites to
determine the types and locations of chemicals present. Sediment and
surface water samples were also taken at Site 25 because this site consists
of 4 major drainages which occasionally contain runoff water during
storm events. Risk assessments were then performed to determine if the
chemicals reported at the sites present a risk to human health. The risk
assessments showed that Sites 4,6,9, 10, 13, 15, 19,20,21, and 22 do
not present an unacceptable risk to human health under a residential
scenario or an industrial scenario. This means that the sites are safe for
homes or industrial use. Site 25 was analyzed under a residential
scenario even though this site consists of drainage channels which are

The wording also frightens me, just what is considered a significant
health threat? Or a major cancer risk? Or being put at any greater risk?
The Marines may feel that a much higher level is no risk than those who
live in the area.
Just how much is some contamination, and just what is needed to pose a
major cancer risk, or a significant health threat? How are these things
gauged? What is significant to one may to you be just fine. The Niagara
River contains high levels of pollutants at its source of industry but
dissipates as it flows downstream. Even though levels downstream are
fine, at the point of where pollutants are flowing into the river the levels
are anything but acceptable. Is this the case with the Base? I would like
some answers that the problems at the base will be corrected at the site of
the contamination. I for one don't give a damn that those in Newport
will not face any problem, I am concerned about the future development
for the base, and those that will be affected by the pollutants won't be put
into the Big Picture to lessen the impact. As was the case when air
pollution was addressed in the Environmental Impact Report (EIR)
report, to put the pollution studies based on how it will affect the L.A.
Basin doesn't address how that air pollution will affect those of us in
South Orange County. Please just give us information that shows how
these things will impact local residents. That is the real issue.
How would you feel if your doctor told you that you have cancer, but at
this time he doesn't feel it's a significant health threat? Wouldn't you
want all of your cancer gone, or would you feel it would be OK to keep
just a little bit of it?
not suitable locations for homes or industrial buildings. Site 25 was also
analyzed for human-health risks due to surface water in San Diego Creek
(which receives runoff from the 4 Site 25 drainages). This analysis
assumed the water in the creek was used for recreational, not residential,
purposes. The risk assessment showed that Site 25 does not present an
unacceptable risk to human health under the residential or recreational
scenario. Based on the remedial investigation and risk assessments, the
Department of the Navy (DON), U.S. EPA, Department of Toxic
Substances Control (DTSC), and the Regional Water Quality Control
Board (RWQCB) concur that No Action is required at Sites 4, 6, 9, 10,
13, 15, 19, 20,21,22, and 25.
TheU.S. EPA has established that excess cancerrisks over I in 10,000 are
generally considered a significant health threat. The criteria for judging the
significanceof cancerrisks is provided in regulations promulgated by the
U.S. Government in the Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA) and the National Oil and
Hazardous Substances Pollution Contingency Plan (NCP).
At Marine Corps Air Station (MCAS) El Toro, risks are calculated for
individuals present at each site. For example, the risk at Site 4 is
calculated assuming that a resident builds a house on the site and lives in
the house for 30 years. Contact with contaminants would occur through
breathing vapors and dust, ingesting soils, and having a contaminant
absorbed through the skin. Using these assumptions, risks to the resident
at Site 4 are less than 1 in 10,000. Risks to individuals who come to the
site for a short time or live away from the site would be much less than
the risks to a resident.
The examples you provide are cases where risk is calculated at a distance
away from the source of contamination. This is not the case in the
human-health risk assessments performed for MCAS El Toro.
The remaining Installation Restoration Program (IRP) sites will be
addressed in future Proposed Plans with the opportunity for public
comment.

Harry and I missed getting to meet and talk with you at the last public
comment meeting on June 18th. We were on vacation and were unable
to make the meeting, but hope to see you at the next regular RAB
meeting.
We were very grateful to get to speak with you in length on May 15th at
the last public comment meeting. We were very convinced by yourself
and Mr. Joyce about the integrity and intentions of the U.S.
Government regarding the level to which MCAS El Toro will be
cleaned up. We believe we heard you both very clearly state that the
base will be cleaned up to a level of "residential use" not to the level of
intended "reuse". Of course there are some exceptions, like the two
landfill sites discussed.
However, after attending an airport forum meeting on June 4th in
Laguna Miguel at which Courtney Wiercioch, Orange County Assistant
Chief Executive Officer and El Toro Project Manager, was one of the
primary speakers, we are again confounded. Ms. Wiercioch clearly
stated that one of the reasons for the County going forward with the
airport proposal for El Toro was that the DECA was running out of
money to clean up the closed bases and that millions of dollars would
be saved by the Government in cleanup costs if the reuse was an airport.
She also indicated that the County of Orange could not afford to finish
the cleanup of the base to "residential" standards after the Marine Corps
vacates it in 1999.
What are we to believe? Please confirm that we were not incorrect in
our assumptions of what both yourself and Mr. Joyce repeatedly tried to
convince us was so.
The majority of the Marine Corps Air Station (MCAS) El Toro sites are
characterized by small amounts of surface soil contamination.
Remediation, where required, will allow for flexibility in future land use,
including use for residential purposes.
The landfill sites will be addressed in future Proposed Plans. These plans
will address the types of restrictions necessary to protect human health
and maintain the integrity of the proposed remedy.

I'm a resident at Leisure World. I'm very unpopular at Leisure World,
because I am vocal in my objection to the fact that our Board of
Directors saw fit to produce a half a million dollars-plus into the —
Proposition A, was it? Don't have an airport at El Toro. And they didn't
ask me or anybody else. They lost the thing. But my treasury and funds
that I have in there that maintain my house are gone. And they've raised
— twice since they've raised our monthly dues. And I feel like the
Board of Directors that took that money should pay it back to our
treasury. So I am very unpopular with the Board of Directors.
I am an inventor. I have a process — two processes for producing
structural concrete out of polluted soil or sand. I've done it a number of
times. And I can do everything that is necessary except pass a
[U.S.] EPA test, which requires you to reduce the material to — so fine,
it's just a little more coarse than face powder. It has to pass through a
300-mesh screen, which it doesn't matter how you have encapsulated
this oil or pollutant, they're going to grind it up so that it is now bare
again and reduced in size so much that it spreads so easily that it — you
can't pass their [U.S.] EPA test.
The Federal Government has seen fit a few years back, along with
Exxon, to try to get oil out of oil-bearing shale in Colorado. I think it
was twenty-some years ago.
And they have never been successful enough to get enough oil to even
supply the process expenditure of energy. So there's no value realized
from getting the oil out of the oil-bearing shale.
The thing that put me on to this process is I make oil-bearing shale out of
this other material. And so, it is necessary that I find something that I
can produce out of this polluted soil or sand that has the same
characteristics of oil-bearing shale and acceptance by the [U.S.] EPA;
that if they were to grind up that oil-bearing shale, they'd get oil out of it.
And they would have a pollutant.
So I feel like their rules are too restrictive. And I sure would like to find
some way of nudging them a tittle.

My first comment is I'd like an answer to my comment. I'd also like an
answer to last time's comment [this refers to a comment made by Ms.
Reavis at the Public Meeting for the Site 24 Vadose Zone Proposed
Plan].
Public comments about the proposed plans are formally addressed in the
form of a Responsiveness Summary that is attached to the Record of
Decision (ROD) for a particular site. Responses are not sent directly
back to the person making the comment. Responses to all comments are
reviewed by the Department of the Navy (DON), the United States
Environmental Protection Agency (U.S. EPA), Department of Toxic
Substances Control (DISC), and the Regional Water Quality Control
Board (RWQCB) as part of the ROD process. This process is not
complete until the ROD is accepted and signed. Responses to individual
comments could change up until this time. Ms. Reavis' comment and the
response to the comment made at the last public meeting have been
incorporated in the Site 24 Vadose Zone ROD.

Okay. I brought up one of the concerns. And that was about the
manganese.
The fact sheet refers to the use of manganese being within background
range in the vicinity. I think that's very vague.
I realize this is a summary report. But I don't believe that that
information is held up in the individual documents. So it's misleading to
the general public, who is not even likely to read all of this.
Metals such as manganese and arsenic occur naturally in soil and rock.
The concentration of these metals varies from place to place depending
on geologic factors. Concentrations of metals can also be impacted by
site-specific activities which can introduce additional metals into the
soils. Background studies are used to determine whether the
concentrations of metals are the result of natural variations or are due to
site-specific activities. This is important because the DON is not
required to remediate metals if the concentration levels are naturally
occurring and are not a result of activities that occurred at the site.
To perform the background study, samples of uncontaminated soils were
gathered from areas in the foothills above Marine Corps Air Station
(MCAS) El Toro and from areas around the Station. These samples were
analyzed for metals and the concentrations of metals were statistically
analyzed to determine the range of natural variation in soils throughout
the Station. The results of this analysis are presented in a technical
memorandum titled "Background and Reference Levels" dated October
1996. This document was reviewed and received concurrence from the
U.S. EPA, DTSC, and the RWQCB and is available for review in the
Public Administrative Record at MCAS El Toro.

I disagree with no cleanup action proposed at eleven sites. I believe if
there were private parties in possession of these properties, and that they
were being sold to another private property outside of the Government,
they would probably need more than no cleanup action proposed.
Well, I can't think of what I was going to say. That'll do for the time
being.
Response
When the Proposed Plan states that the levels of metals are within the
background range of these metals in the vicinity of MCAS El Toro, this
means that the concentration of metals at the site does not exceed natural
concentrations in the area and is most likely due to natural variations and
not due to any activities that occurred at the sites.
No Action decisions at MCAS El Toro conform to regulatory
requirements established in the CERCLA and in the National Oil and
Hazardous Substances Pollution Contingency Plan (NCP). These
regulatory requirements are the same whether the property is privately
owned or owned by the federal government.
Remedial investigations and remedial actions taken at MCAS El Toro are
carefully monitored by the U.S. EPA, the DTSC, and the RWQCB.
These agencies assisted in the development and review of the work plan,
sampling plan, remedial investigation reports, and other documents
associated with the Installation Restoration Program (IRP) site
investigations. All of these agencies have concurred that No Action is
appropriate for Sites 4, 6, 9, 10, 13, 15, 19, 20, 21, 22, and 25.

Oh, I'd also like to go on record that I don't consider these to be
meetings. They are and have been termed as "open houses." I'd
appreciate it if they were called such on the public information that they
put out. There's no forum for the people who do come to the meeting to
be able to convey their interests, their concerns, or their questions to
other people. And I think that process of thinking is necessary, because
some people don't know what their questions are. So we need to be able
to hear other people's thoughts, to work off of that. While this satisfies
the Government's requirements of going through the process and making
the information available to the public, I think that it's less than the
public needs to become informed.
I also never saw anything published in the paper on this. If it was in the
paper, it wasn't very well handled. And that is nothing against Matthew.
I know he's in charge of this. He's a nice guy.
But beyond fulfilling the legal requirements of what the government
wants, I just don't think that it's what the public needs.
The public meeting held on 31 July 1997 conforms to guidance in
CERCLA and NCP and was chosen because it allowed residents and
other interested parties to meet and converse with DON and agency
personnel to obtain information and ask questions which they might have
regarding the No Action sites. It was felt that this type of meeting would
allow all people attending the meeting, even those who are generally
reluctant to speak before a large group, to have an opportunity to ask
questions, raise issues, and voice their concerns. The positive response
from the public on both the questionnaires and in interviews with the
public recorder attest to the effectiveness of the meeting format.
The public meeting was announced in the Los Angeles Times (Orange
County edition) and the Orange County Register on 10 June 1997. The
public meeting was also announced in the Proposed Plan for the No
Action sites which was mailed to approximately 1,800 households,
public officials and agencies, and businesses.

I enjoyed talking with Lynn Hornecker. She's with the Engineering
Command. And I found it marvelous. She gave a wonderful explanation
about that program, and the IRP.
I also talked to Dante Tedaldi. He's with Bechtel. And 1 found he was
very helpful in regard to risk assessment.
And I also talked with Andrea Temeshy. She's the toxicologist for
Bechtel, and I found that her conversation with me was terribly valuable.
And Andy Piszkin, I think I enjoyed Andy Piszkin's comments.
And Joseph Joyce, I'd also like to add, he was very helpful, too.
And I feel this was a wonderful opportunity to see the overall — the big
picture. It really showed the big picture. And I think it's absolutely
necessary to have this type of forum.
Comment noted. Please see the response to Comment 11B for a
discussion of the meeting format and responses to Comments 2,4, and 6
for a discussion of risks at the No Action sites.
Methyl-tert-butyl ether (MTBE) is a synthetic organic ether that has
been used to enhance the octane level in gasoline since the early
1980s. MTBE has recently become more widely used as a result of
the Clean Air Act Amendments of 1990, which require use of
oxygenated fuels or reformulated gasoline in certain metropolitan
areas where atmospheric concentrations of ozone or carbon
monoxide exceed national ambient air quality standards.
Soil samples taken from the No Action sites were not analyzed for
MTBE because the fuel materials which were known to be released at
these sites (e.g., JP-5, diesel oil, diesel fuel) do not contain MTBE. In

However, there was one — I did have, at one time, some very major
misgivings regarding this type of forum. And now, I think I was

And — But I do believe that this is just one mode of making a
presentation on this particular subject. But there's — There are other
modes, but this is definitely needed. I found it extremely illuminating
and very insightful. And it helped me to understand the big picture, as I
said earlier.
1 think what I'm concerned about right now is methyl-tert-butyl ether
(MTBE) concentrations. And I'm also concerned about teachability of
the — I'm talking about the leachate emissions. That's a worrisome
thing to me. I'm still not, maybe, totally convinced that the — that the
human — The risk to human health — I haven't really made — I don't
have enough information to determine whether the risk to human health
is a factor here in this presentation that I've seen this evening or not.
I'm inclined to think that — As 1 said, Andrea Temeshy's presentations
indicate to me that pica factor is — has been considered, and that they
felt that it was not a risk.
So I would — I would say that we need to have more of these. And I
think that I approve of it wholeheartedly. However, a public forum with
a dog and pony show where we can participate and where we can have a
microphone, each individual can come up and maybe make a
presentation as to how they feel about — rather than just doing it, you
know, through a Court Reporter. This is fine. This is one mode. But I
think it's necessary — Other people want to know how other people feel.
And in this particular instance, this isn't reflected. This particular forum
or presentation or exhibition can't reflect that, because it's not set up that
way.
addition, the releases that were known to have occurred at the sites
generally took place before 1990 when the use of MTBE became
widespread.

Being a resident of Aliso Viejo I am very concerned about the base
turning into an International Airport.
However, I am very concerned that both pro-airport and anti-airport
proponents are confusing the quality of cleanup with the reuse.
Regardless of the reuse, I am confident the U.S. Government has the
welfare of the future of our children's children in mind when expending
all funds available now and in the future for residential cleanup.
Response
The Department of the Navy (DON) agrees that the issues of remediation
and reuse need to be considered separately. It has always been the
DON's intent to remediate property to the extent required under the
Comprehensive Environmental Response, Compensation, and Liability
Act (CERCLA) regardless of future land use. In most cases, this means
that the property could be used for residential, recreational, or
commercial purposes. The risk assessment performed for these sites
showed these sites are acceptable for unrestricted use as they are, without
remediation.

Comments
1 see no problem with the No Action plan. It is a cost-effective approach
to remediation at El Tore. If other sites are not significantly impacted
above background, a similar approach should be implemented.
The meeting structure is adequate for answering questions, but it does
not provide an opportunity for community action and participation.
Response
Comment noted. Thank you for your support.
