Dear Mr. Radelow:
EEI has completed the following Limited Phase II Environmental Site Assessment (ESA) Report for the
above referenced subject property (Figure 1). The following report discusses sampling activities and our
conclusions.
BACKGROUND INFORMATION
Based on a "Site Plan Scheme F" prepared by SPGA Architecture dated July 20, 2009, the overall project
site consists of an approximately 16-acre section located on the southwest comer of El Camino Real and
Palomar Airport Road, in the City of Carlsbad, San Diego County, Califomia. The greater portion (12.02
acres) of the overall site is proposed to be developed as a Lowe's Home Improvement Warehouse (HIW).
The balance (4.71 acres) will be developed by SUDBERRY PROPERTIES, INC. as several out-pads
totaling approximately 40,000 square feet, and a retention pond.

Limited Phase II Environmental Site Assessment Report January 11, 2010
SUDBERRY PROPERTIES, INC. - Palomar Airport Commons EEI Project No. SUD-70986.3
The subject site was fonnerly occupied by the Olympic Resort, which contained asphalt parking,
tennis courts, buildings, a pool, and a golf practice range. The site is currently undergoing demolition
and improvements in preparation for future planned development activities. At the time of this
investigation, remaining onsite is the former Olympic Resort main hotel building, tennis courts, and
golf practice range.
Note: a portion of the golf practice (central portion of the overall subject property) has been filled
with what appeared to be import soil. It is unknown at this time the origin of the import material and
whether or not environmental profile testing was conducted, prior to placement. Figure 2 delineates
the approximate boundary of the import fill material observed during field activities associated with
this investigation.
EEI recently completed a Phase 1 ESA (EEI, 2009) for the subject property. Based on the findings of
the Phase I ESA, the offsite and adjacent (420 feet north of the subject property) former Palomar
Airport Landfill was identified as being a recognized environmental concem, warranting further
investigation.
The landfill, which was divided into three (3) separate Units, operated from 1962 to 1975. Unit 3 of
the landfill, located immediately north of the subject property, was the largest of the three (3) units
and reportedly accepted residential, commercial, and agricultural waste. Occasionally, the facility
also accepted industrial wastes, including: paints, oils and thinners, treated sewage sludge, and
medical wastes for disposal.
According to Phase I ESA research information (EEI, 2009), the landfill was unlined. Presently,
there are ongoing environmental investigation and mitigation efforts in association with documented
soil and groundwater impacts at the landfill site. Shallow groundwater beneath the landfill has been
impacted by solvents and fuel hydrocarbons, and appears to have migrated beneath the subject
property. Furthermore, the presence of methane, a landfill gas, has been confirmed at concentrations
above regulatory threshold limits within Unit 3. A series of vapor extraction systems, flare stations,
and monitoring points (including two along the northem subject property boundary) have been
installed to evaluate and mitigate landfill gas issues.
INVESTIGATION OBJECTIVE
The objective of this investigation was to evaluate soil gas and groundwater beneath the subject
property for volatile organic chemicals (VOCs) and landfill gases in association with the offsite and
former Palomar Airport Landfill, which could impact fiiture planned site improvements/development.
FIELD ACTIVITIES
Field activities were conducted on December 23, 2009. Boring locations were pre-determined and
based on the location of the offsite and adjacent former Palomar Airport landfill and future planned
site development. A total of total of six (6) soil gas probes were advanced beneath the subject
property (Figure 2). Additionally, one groundwater sample (GW-1) was collected from beneath the
site. A track-mounted GeoprobeTw Direct Push drill rig was used to advance the soil gas borings,
while a tmck-mounted hollow stem auger (HSA) was used to advance to and sample groundwater.
Drilling services were provided by H&P Mobile Geochemistry and Califomia Pacific drilling.

Soil Gas Investigation
A total of six (6) soil gas probes were advanced beneath the subject property and to a target depth of
five feet below ground surface (bgs) (Figure 2).
After advancing the boring to the target depth, small diameter (Vi-inch diameter) Teflon''^** tubing was
fitted with a sample tip (to assist in recovering a representative soil vapor sample), and placed down
the boring. A one-foot sand pack, consisting of #3 Monterey™ sand was placed into the borehole,
followed by hydrated bentonite chips to the surface. The probe was completed at the surface with a
bentonite seal and a one-way gas tight sample valve.
Prior to sample collection, the vapor probes were left in the ground for a minimum of 30 minutes to
allow for subsurface conditions to equilibrate. The sample tubing was then purged of three volumes
of air using a glass syringe. A 500 milliliter Tedlar^M bag, provided by H&P Mobile Geochemistry,
was then filled through by extracting soil gas with the glass syringe through a three-way valve.
Immediately after sample collection the Tedlar''''^ bag was labeled with a number unique to the
sample, and placed in a container for transport to H&P Mobile Geochemistry under standard Chain-
of-Custody (COC) documentation. After the sample was collected the vapor probe was removed and
the boring backfilled with hydrated bentonite chips, and a dirt surface cap.
Note: soil vapor probe installation generally followed the Department of Toxic Substances Control
(DTSC)/Califomia Regional Water Quality Control Board - Los Angeles Region "Advisory - Active
Soil Gas Investigations" guidance, dated January 28, 2004.
Groundwater Investigation
A tmck mounted hollow stem auger (HSA) drill rig was used to advance a boring to groundwater
beneath the subject property. Boring GW-1 (Figure 2) was advanced to approximately 45 feet bgs,
while groundwater was encountered at approximately 37 feet bgs. To facilitate the collection of
groundwater sample collection, a temporary well, consisting of a 2-inch diameter PVC casing, was
placed down the boring.
Groundwater samples were collected from the well using a new 1/2-inch diameter polyethylene
bailer. Once extracted, the water was transferred directly into six (6) laboratory supplied 40 milliliter
(ml) volatile organic analysis (VOA) viles preserved with hydrochloric acid (HCl). After sample
collection, the containers were custody sealed, and labeled with a number unique to the sample. The
samples were placed in a chilled cooler, pending delivery to H&P Mobile Geochemistry, under
standard COC documentation.
Upon completion of sample collection, the temporary PVC well was removed, and the boring was
subsequently backfilled with bentonite grout and native soil.
LABORATORY ANALYTICAL PROGRAM
Soil gas samples collected during this investigation were analyzed for methane by USEPA Test
Method 8015M and volatile organic compounds (VOCs) by USEPA Test Method 8260B.
Groundwater samples collected during this assessment were analyzed for VOCs by USEPA Test
Method 8260B. Complete laboratory analytical reports with COC documentation are included in
Appendix A.

QUALITY ASSURANCE/QUALITY CONTROL
For samples collected during this assessment, the following QA/QC analysis was conducted by the
contact laboratory:
• Method/Blank Sample
These types of QA/QC checks are employed routinely by laboratories to ensure accurate data. The
standard operating procedures for each analysis have specific types and frequency of QA/QC checks
which are followed at a minimum. Laboratory QA/QC checks also include an evaluation of blanks,
precision, accuracy, and recovery.
EEI reviewed the laboratory's documentation for all samples submitted during this assessment to
ensure that appropriate sample collection, extraction times, holding times, analysis and acceptable
QA/QC limits were in compliance. All samples analyzed during the referenced reporting period were
in compliance with the appropriate QA/QC standards employed by the laboratory.
LABORATORY ANALYTICAL RESULTS
The following section discusses laboratory analytical results. The attached Table 1 and 2 is a
summary of laboratory analytical results. Complete laboratory analytical results and COC
documentation are included as Appendix A.
Soil Gas Results
A total of six (6) soil gas samples were analyzed for methane and VOCs by USEPA Test Method
8015M and 8260B, respectively. The following bulleted items summarize chemicals of concem
detected:
• Methane was only reported in sample SG4 at 17 parts per million volume (ppmv). All other
samples analyzed reported methane at less than the laboratory reporting limit.
• Total xylenes were reported in sample SG4 at 750 micrograms per cubic meter (|ig/m^). All
other samples analyzed reported total xylenes at less than the laboratory reporting limit.
• No other VOCs, including Tetrachloroethene (PCE), Trichloroethene (TCE), cis-1,2-
Dichloroethene, 1,1 -Dichloroethene or Vinyl Chloride were reported above their respective
laboratory reporting limit.
Groundwater Results
A single groundwater sample, GW-1, was collected and analyzed for VOCs by USEPA Test Method
8260B during this investigation.
• No VOCs were detected above the laboratory reporting limit in groundwater samples
analyzed during this investigation.

SUDBERRY PROPERTIES, INC. - Palomar Airport Commons EEI Project No. SUD-70986.3
DISCUSSION OF FINDINGS
A total of six (6) soil gas samples and one groundwater sample were collected beneath the subject
property. All soil gas samples were submitted for testing of methane and VOCs by USEPA Test
Method 8015M and 8260B, respectively, while groundwater samples were analyzed for VOCs only.
Reported soil vapor concentrations were compared to Califomia Human Health Screening Levels
(CHHSLs) for Shallow Soil Gas - Commercial/Industrial Land Use Only values (Cal-EPA, 2005).
The CHHSLs are concentrations of 18 hazardous chemicals that are used to estimate and compare
reported concentrations in soil gas to risk to human health.
The following chemicals of concem were detected above the laboratory reporting limit and have
CHHSL lookup values: total xylenes.
• Total xylenes were reported at 750 jig/m^ which is less than the commercial and residential
CHHSL of 879,000 \ig/m^ and 315,000 |ig/m^ respectively.
Methane was reported at 17 ppmv in sample SG4, only. It should be noted that methane does not
have a CHHSL screening level value. Methane is not toxic; however, it can be highly flammable and
may form explosive mixtures with air (i.e., the lower explosive limit [LEL] for methane is 50,000
parts per million). The concentration of methane reported (17 ppmv) during this investigation is well
below this threshold and does not appear to pose a significant risk to human health or the
environment.
Groundwater was encountered at a depth of 37 feet bgs and a sample (GW-1) was collected. No
concentrations of VOCs in sample GW-1 were reported above the laboratory reporting limit.
CONCLUSIONS
Based on the results of this investigation, EEI has the following conclusions:
• Low levels of methane and total xylenes were reported in soil gas during this investigation.
The concentrations were less than commercial/residential screening levels (in the case of total
xylenes) and/or the lower explosive limit (i.e., methane). No VOCs were detected above the
laboratory reporting limit in the groundwater sample collected during this investigation.
