1 BACKGROUND
SCS Engineers (SCS) understands that 821 Main Street consists of two full parcels of land (APNs
644-050-13 & -14)and the western portion of a third parcel of land (APN 644-050-08) totaling
approximately 17.11 acres of land in Chula Vista, California (Site) (Figure 1). The Site consists of a
vacant hillside that is bordered by Main Street to the south, and several industrial properties to the
east and upgradient of the Site, including a general contractor yard and vehicle storage and salvage
lots. The Client is proposing to purchase the Site for development into an industrial land use.
SCS completed a report titled Phase I Environmental Site Assessment for the Site, dated September
23, 2021 (Phase I ESA). Although the Phase I ESA did not reveal evidence of recognized
environmental conditions, after discussions with the Client and the Client’s investor, the Client is
requesting subsurface assessment activities for the following environmental concerns that were
identified in the Phase I ESA:
•On-Site drainage channels and adjacent upgradient industrial properties – two drainage
channels transect the central and western portions of the Site that convey surface water
from upgradient industrial properties, and portions of these drainage channels are unlined
(Figures 2 and 3). The central portion of the north adjacent property at 800 to 880 Energy
Way, identified as LKQ Pick Your Part that serves as an automobile maintenance/storage
yard (former wrecking yard), was interpreted to drain into the central drainage system that
transects the Site. The western drainage channel adjacent to the northwest tenant, FJ Willert
Contracting at 1869 Nirvana Way, was obscured due to heavy vegetation.
•Totes adjacent to the Site with unidentified contents – several totes with unidentified dark
colored liquid and solid contents, with grassy vegetation growing from within the totes, were
observed adjacent to the northern property line toward the eastern edge of the Site (Figures
2 and 3) at the time of the Phase I ESA (note that these totes were removed from the
adjacent northern property at the time that subsurface assessment activities were
conducted by SCS on November 11, 2021). These totes are believed to be derived from the
adjacent LKQ Pick Your Part facility at 800 to 880 Energy Way.
Based on the findings presented in the Phase I ESA, SCS previously collected three representative
surficial soil samples from sediments within the on-Site drainage channels on July 13, 2021, and
analyzed the samples for constituents of concern (CoCs) including total petroleum hydrocarbons
(TPH), volatile organic compounds (VOCs), and Title 22 metals. The results of the sampling indicated
detectable levels of TPH that were below health risk-based screening levels, and were transmitted to
the Client within an email submittal.
Based on a request from the Client’s investor and conversations with the Client, SCS has conducted
the following scope of services consisting of additional shallow soil sampling as well as soil vapor
sampling to additionally assess for the potential environmental concerns that were identified in the
Phase I ESA associated with the drainage channels and adjacent upgradient industrial properties
and totes adjacent to the Site with unidentified contents.
2 OBJECTIVES
The objectives of the scope of services were to:
Phase II ESA www.scsengineers.com

• Assess the possible presence and concentrations of CoCs (i.e., petroleum hydrocarbons,
polycyclic aromatic hydrocarbons [PAHs], VOCs, and Title 22 metals) within representative
locations within the on-Site drainage channels, in connection with possible impacts from the
northern adjacent industrial properties.
• Assess the possible presence and concentrations of VOCs in the shallow soil vapor beneath
the Site in connection with possible releases from the northern adjacent industrial properties
that may have impacted the Site.
• Assess the likelihood that Significant 1 human health risk exists at the Site as a result of
vapor phase migration of VOCs.
3 PHASE II ESA
PREPARATION FOR FIELDWORK
Preparation of Health and Safety Plan
A health and safety plan for work conducted at the Site and workers within the “exclusion zone” is
required pursuant to the regulations found in 29 Code of Federal Regulations (CFR) Part 1910.120
and California Code of Regulations (CCR), Title 8, Section 5192. Therefore, a health and safety plan
was prepared for the proposed work scope, which outlined the potential chemical and physical
hazards that may have been encountered during drilling and sampling activities. The appropriate
personal protective equipment and emergency response procedures for the anticipated Site-specific
chemical and physical hazards were detailed in this plan. SCS and contracted personnel involved
with the proposed field work were required to read and sign this document in order to encourage
proper health and safety practices.
Utility Search and Markout
SCS notified Underground Service Alert on November 4, 2021, as required by state law, prior to
drilling and sampling activities and was issued ticket number B213080820. In addition, a private
utility locator, Subsurface Alert, was subcontracted to clear the proposed boring locations for
possible subsurface utility conflicts. These procedures were designed to minimize the likelihood of
drilling into a subsurface utility.
FIELD ACTIVITIES
Soil Vapor Sampling and Analysis
On November 11, 2021, SCS oversaw the drilling and installation of three soil vapor probes (SV1
through SV3) to assess the possible presence and concentrations of VOCs in the soil vapor in
connection with possible subsurface impacts from the adjacent upgradient industrial facilities. The
following table describes the proposed soil vapor sampling locations and depth. Locations of soil
vapor samples are included in Figure 2.

The soil vapor sample borings SV1 through SV3 were advanced with an electric rotohammer to the
attempted depth of 5 feet below grade, although due to practical refusal encountered with the
rotohammer due to stiff and rocky soil, the borings were advanced to the maximum attainable
depths ranging from approximately 2 to 4 feet below grade. Note that due to the rugged and
slopped nature of the Site, it was not considered feasible to use a drill rig or limited access drill rig to
advance the proposed soil vapor borings.
Soil vapor sampling activities were conducted in general accordance with the Department of Toxic
Substances Control (DTSC), Los Angeles Regional Water Quality Control Board (RWQCB), and San
Francisco RWQCB Advisory on Active Soil Gas Investigations, dated July 2015. A temporary soil
vapor well, consisting of Nylaflow™ tubing attached to a soil gas probe tip, was installed near the
bottom of each boring. An appropriate sand pack a minimum of 6 inches thick was placed around
the soil gas probe tip, and the borings were backfilled with at least 6 inches of dry granular bentonite
above each sample port, then topped with hydrated granular bentonite to the surface. The soil vapor
sampling probes were allowed to stabilize for approximately 2 hours prior to sampling, followed by
removing the DTSC-default of three purge volumes, and performing a shut-in test and leak test.
Soil vapor samples were collected from the soil vapor sampling probes by collecting soil vapor drawn
through the probes into laboratory-provided glass syringes. Soil vapor samples were delivered to an
off-Site state-certified, mobile laboratory (H&P Mobile Geochemistry) and analyzed for VOCs in
general accordance with U.S. Environmental Protection Agency (EPA) Method TO-15. In accordance
with the DTSC guidance, one replicate sample was analyzed (SV3-3 Rep). Chain-of-custody
procedures were implemented for sample tracking.
Soil Sampling and Analysis
On July 13, 2021, SCS collected soil samples using a trowel (borings SB1 through SB3) to the total
depth of 0.5 feet below grade at the Site. On November 11, 2021, SCS advanced five additional soil
borings by using a hand-held auger (borings SB4 through SB8) to total depths of up to 2.0 feet below
grade at the Site, collecting soil samples at approximate depths of 0.5 feet below grade and 1 to 2
feet below grade. Locations of the soil samples are included in Figure 3. The following table
summarizes the completed soil borings with depths and laboratory analysis for soil samples.

Soil samples were collected with the trowel or hand-held auger and were transferred directly from
the blade or barrel of the hand auger with a gloved hand into a new 4-ounce glass jar.
The sampling equipment was decontaminated on-Site between soil samples to minimize the
likelihood of “cross-contaminating” the samples and to minimize the potential for a “false positive” in
the soil samples analyzed. The soil cuttings from the hand auger borings were used to backfill the
borings.
The sample containers were labeled and delivered to an off-Site laboratory for analysis. Chain-of-
custody procedures were implemented for sample tracking. A copy of the laboratory analytical report
is provided in Appendix A.
SOIL SCREENING REGULATORY CRITERIA FOR COC-BEARING SOIL
Concentrations of CoCs that are reported by the laboratory in soils at the Site are compared to
applicable regulatory screening values to assess whether certain soils will require segregation and
proper management during Site development.
There are two categories of mitigation work that will be required and are principally based upon risk-
based corrective action. These categories include:
o Health Risk-Based Mitigation Criteria - risk-driven remediation required by future land uses
and protection of workers, and
Phase II ESA www.scsengineers.com
5
o Waste-Based Mitigation Criteria - in the event that soil is exported off Site, in which case soil
may be considered regulated waste provided it contains detectable concentrations of TPH,
VOCs, PAHs, or elevated concentrations of metals such as lead or arsenic.
Soil screening criteria are used in this Report for comparison of the reported soil sample results to
applicable health risk-based and waste-based soil for the detected CoCs. The applicable soil
screening applied in the “Findings” section below includes the following:
Health Risk-Based Mitigation Criteria
For health risk-based screening purposes, to screen soil for possible risks to residential users and
workers at the Site:
• For TPH and VOCs, the San Francisco Bay Regional Water Quality Control Board (SFRWQCB)
Environmental Screening Levels (ESLs) for commercial/industrial users, dated 2019, revision
2
• For SVOCs and metals, the DTSC Human and Ecological Risk Office (HERO) Human Health
Risk Assessment (HHRA) Note Number 3, June 2020: Recommended Screening Levels
(RSLs) for commercial/industrial soil are used.
• For other PAHs where the DTSC RSLs are not established (phenanthrene), the EPA RSLs for
commercial/industrial soil, November 2021, are used.
Waste-Based Mitigation Criteria
For waste-based screening purposes, the below criteria are applied in the event that soil is exported
from the Site. Also, based on our experience working with the San Diego County Department of
Health Services (DEH), it is recommended that soil that is classified as a hazardous waste be
exported to an appropriately licensed facility rather than be left on-Site.
• For “clean” or inert (Inert 2) soil that is exported from the Site, the San Diego RWQCB Tier 1
Soil Screening Levels 3 (SSLs) established in the RWQCB Order No. R9-2019-0005,
Conditional Waivers of Waste Discharge Requirements for Low Threat Discharges in the San
Diego Region, May 2019 (Waiver) are intended to be the criteria by which exported waste soil
is judged to be inert, described within the Waiver as “inert waste soils that can be reused
without restriction.”
2 Inert soil - For the purposes of this Report, Inert is defined as soil that does not contain detectable concentrations of
constituents of concern with the possible exception of California Code Regulations Title 22 metals (with metals
concentrations below the San Diego Regional Water Quality Control Board [RWQCB] Tier 1 Soil Screening Levels using
a 90 percent upper confidence limit), or leachable concentrations of organic constituents that are consistent with the
definition of “inert waste” specified in California Code of Regulations Title 27, section 20230, consistent with the
RWQCB Order No. R9-2019-0005, Conditional Waivers of Waste Discharge Requirements for Low Threat Discharges
in the San Diego Region, May 2019 (Waiver). This soil may consist of native/formational material as well as fill soil
that does not have significant quantities of debris.
3 The Tier 1 SSLs presented in the RWQCB Waiver are intended to be the criteria by which soils are judged to be Inert
waste soils that can be reused without restriction, subject to the General Waiver Conditions. The General Waiver
Conditions stipulate that discharges/disposal of solid wastes to land must not be allowed to directly or indirectly enter
any municipal separate storm sewer system (MS4s) or surface waters of the State, must not cause or threaten to
cause a condition of contamination, pollution, or nuisance, and must comply with local, State, and federal ordinances
and regulations and obtain any required permits, certifications, and/or licenses.
Phase II ESA www.scsengineers.com
6
o For chemical CoCs including TPH, VOCs, and PAHs, all soil containing any detectable
or leachable concentrations of chemical CoCs proposed for export off Site would
need to be disposed of as regulated, non-hazardous waste at a minimum per the Tier
1 SSLs.
o For metals that are naturally occurring, the Tier 1 SSL for lead is 23.9 milligrams per
kilogram (mg/kg) and the Tier 1 SSL for arsenic is 3.5 mg/kg. If soil was to be
exported as Inert, excavated Site soils must be shown through the collection of soil
samples and analysis for lead and other metals, with the 90% upper confidence limit
(UCL), to be below the Tier 1 SSL.
• Non-hazardous regulated waste soils are exported soils that have concentrations of CoCs
that exceed the Tier 1 SSLs (discussed above), and also have concentrations of CoCs below
hazardous waste-based criteria (discussed below). Non-hazardous regulated soils must be
disposed of at a properly licensed facility, such as a landfill. The acceptance of non-
hazardous soils at disposal facilities are subject to the acceptance criteria established by
these facilities.
• For characterizing soil as hazardous waste, the California Code of Regulations, Title 22
Article 3, was used.
o Soil is characterized as a California hazardous waste, at a minimum, upon
exceedance of the total concentrations of a CoC to the Total Threshold Limit
Concentration (TTLC), and/or by comparing the results of a Waste Extraction Test
(WET) to the Soluble Threshold Limit Concentration (STLC).
o Soil is characterized as a federal or Resource, Conservation, and Recovery Act (RCRA)
hazardous waste through an exceedance of Toxicity Characteristic Leaching
Procedure (TCLP) laboratory results upon comparison to the respective Maximum
Contaminant Concentration for the Toxicity Characteristic (MCCTC).

LABORATORY ANALYTICAL RESULTS AND SCREENING
Soil Vapor Sample Analytical Results
A summary of the laboratory analytical results for soil vapor is presented below. A complete listing of
the results is presented in the laboratory analytical report included in Appendix A. The data are
presented in Table 1 and depicted on Figure 2.
VOCs
A total of four soil vapor samples, identified as SV1-4, SV2-2, SV3-3, and SV3-3 Rep, were analyzed
for VOCs in general accordance with EPA Method TO-15.
Carbon disulfide was reported to be present in one of the four soil vapor samples at the
concentration of 47 micrograms per liter (µg/L) (SV2-2).
Toluene was reported to be present in three of the four soil vapor samples at concentrations ranging
from 8.8 µg/L (SV3-3 Rep) and 19 µg/L (SV2-2).
m,p-Xylene was reported to be present in two of the four soil vapor samples at concentrations
ranging from 9.2 µg/L (SV3-3) and 26 µg/L (SV2-2).
o-Xylene was reported to be present in one of the four soil vapor samples at the concentration of 7.2
µg/L (SV2-2).
1,2,4-Trimethlybenzene was reported to be present in one of the four soil vapor samples at the
concentration of 12 µg/L (SV2-2).
Chloroform was reported to be present in one of the four soil vapor samples at the concentration of
9.0 µg/L (SV1-4).
All other VOCs analyzed were reported to be below the respective laboratory reporting limits. Please
refer to the analytical laboratory reports contained in Appendix A for a full listing of VOCs analyzed
and their respective reporting limits.
Since VOCs were reported to be present above laboratory reporting limits, a vapor intrusion risk
screening (VIRS) was conducted to assess the likelihood that a Significant vapor intrusion risk exists
at the Site as a result of vapor phase migration of CVOCs. See the “Vapor Intrusion Risk Screening
(VIRS)” section below.
VOCs in Soil Vapor
The VOCs reported to be present in soil vapor beneath the Site included carbon disulfide, toluene,
m,p-xylene, o-xylene, 1,2,4-trimethylbenzene, and chloroform. Carbon disulfide, toluene, m,p-xylene,
o-xylene, and 1,2,4-trimethylbenzene are typical constituents of petroleum hydrocarbons, likely from
the nearby industrial properties or other off-Site sources. Chloroform is a routine drinking water
disinfection byproduct (trihalomethanes) and is often present in soil and soil vapor from treated tap
water via irrigation or other sources of drinking water. Chloroform is formed when chlorine reacts
with natural organic humic materials and bromine via the haloform reaction in water.4 Overall, based
on the low concentrations at which they were detected, it’s unlikely the VOCs in soil vapor resulted

from a point source or significant release at the Site, but more likely have migrated beneath the Site
from the nearby industrial properties or another off-Site source.
Vapor Intrusion Risk Screening (VIRS)
Since VOCs were reported to be present in soil vapor beneath the Site, a VIRS was conducted to
assess the potential for Significant human health risk posed to occupants of the proposed
commercial/industrial Site buildings due to the upward migration of VOCs in soil vapor. SCS
understands that as of January 24, 2019, the DTSC has archived the Johnson and Ettinger Human
Health Risk Assessment Model. Therefore, SCS has conducted a vapor intrusion risk screening using
current DTSC screening criteria, as described below, and the Site-specific slab attenuation factor, as
described above.
Approach
VOCs may originate from either impacted soil or groundwater. In this case, VOCs are interpreted to
be from possible subsurface impacts from the adjacent upgradient industrial facilities or another off-
Site source, which were able to migrate in soil vapor beneath the Site. The highest soil vapor
concentrations detected beneath the Site were conservatively assumed to be present beneath the
entire Site to estimate conservative case-scenario-predicted indoor air concentrations for the future
commercial/industrial buildings at the Site. The estimates of the theoretical indoor air
concentrations were then compared against the most recently published screening levels 5 to assess
the potential for Significant human health risk posed to commercial/industrial users of the Site due
to the upward migration of VOCs in soil vapor.
The VIRS was conducted using the DTSC default Attenuation Factor6 (AF) of 0.0005 for future
commercial industrial buildings. To be conservative, the AF was applied to the highest reported
concentration of each constituent (carbon disulfide, toluene, m,p-xylene, o-xylene, 1,2,4-
trimethlybenzene, and chloroform) reported in soil vapor. The resulting values were compared
against the DTSC-Modified Screening Levels (DTSC-SLs) provided in DTSC Human Health Risk
Assessment (HHRA) Note 3.5
VIRS Results
The maximum reported concentrations of VOCs detected at the Site are presented in the table
below, along with the associated DTSC-SL. Please note that only the constituents reported to be
present beneath the Site building were evaluated.

^ A DTSC-SL has not been established for this constituent (carbon disulfide, m,p- and o-xylenes, and 1, 2, 4-
trimethylbenzene). The Environmental Protection Agency (EPA) Regional Screening Level (RSL), dated November 2021,
was used for this constituent.
After applying the DTSC attenuation factor of 0.0005 for a future commercial/industrial land use to
the maximum reported concentrations of the constituents reported to be present beneath the Site
(carbon disulfide, toluene, m,p-xylene, o-xylene, 1,2,4-trimethylbenzene, and chloroform), the
maximum theoretical concentrations of VOCs in indoor air at the Site are below the
commercial/industrial screening levels (DTSC-SLs or RSLs).7
Soil Sample Analytical Results
A summary of the laboratory analytical results for soil is presented below, along with screening the
reported results to the Site to the Health Risk-Based Mitigation Criteria and Waste-Based Mitigation
Criteria, as defined in the “Soil Screening Regulatory Criteria for CoC-Bearing Soil” section above. A
complete listing of the results is presented in the laboratory analytical report included in Appendix A.
The data are presented in Tables 1 through 3 and depicted on Figure 3.
Lead and Other Metals
Soil analytical results for lead and other metals are summarized here:
7 Note that vapor intrusion standards are currently in a state of transition, and if more conservative standards are
adopted, it is possible that in using the vapor concentration data obtained by SCS that the derived theoretical indoor
air concentrations exceed applicable indoor air screening criteria. For example, if a default attenuation factor of 0.03
for sub-slab soil vapor and “near-source” exterior soil vapor was used, as described in 2015 by USEPA and USEPA and
in February 2020 by DTSC in their Draft Supplemental Guidance: Screening and Evaluating Vapor Intrusion, the
reported maximum chloroform concentration at the Site exceed residential EPA screening level (U.S. Environmental
Protection Agency Office of Solid Waste and Emergency Response (OSWER) June 2015 – OWSER Technical Guide for
Assessing and Mitigating the Vapor Intrusion Pathway from Subsurface Vapor Sources to Indoor Air). However, the
2015 EPA Guidance indicates attenuation factors for deeper soil vapor data would be expected to be less than those
for sub-slab soil vapor due to additional attenuation through the vadose zone. It is our understanding that, based on
recent projects with DTSC oversight, the DTSC is still allowing the use of the DTSC 2011 Guidance and attenuation
factors. Therefore, based on our experience and because this assessment includes deeper soil vapor sampling depths
than sub-slab depths, the DTSC 2011 Guidance is used herein.

Waste-Based Screening - Tier 1 SSLs = Tier 1 Soil Screening Level for inert waste soils that can be
reused without restriction. For exceedances, the 90 percent upper confidence limit was used
to derive a Site-specific value, as discussed in the Report below.
Health Risk-Based Screening – DTSC RSL/ EPA RSL = Health Risk-Based Criteria - For metals, the DTSC
HERO HHRA Note Number: 3, June 2020, using the RSLs for commercial/ industrial soil and
cancer endpoint, or, for other metals not listed in HHRA Note 3, the Regional Screening levels
for commercial/ industrial soil, provided by the EPA and updated as of May 2021 were used.
< - Concentration reported below the listed laboratory reporting limit.
* - For arsenic, although the DTSC RSL is 0.11 mg/kg, concentrations of naturally occurring
arsenic typically exceed human health risk screening criteria. Therefore, the DTSC upper-
bound background concentration for arsenic of 12 mg/kg was used.
Red font – the maximum Site concentration for a particular metal exceeds the Tier 1 SSL.
Comparison of Metals Concentrations to Waste-Based Mitigation Criteria (i.e., for
Soil Export)
The analytical results of the Title 22 metal analyses were compared to the respective Tier 1 SSL for
each metal, which are established in the San Diego RWQCB Waiver2 and apply to waste export (i.e.,
for soil that is exported from the Site only). Tier 1 SSLs were exceeded in select sample results for
lead, arsenic, and zinc. Below is a discussion of each metal that was reported with concentrations
that exceed the Tier 1 SSL.
Arsenic – Three soil samples were reported to exceed the Tier 1 SSL for arsenic (samples SB1, SB2,
and SB3); they were collected from a depth of approximately 0.5 feet within the drainage channels
and reported with arsenic concentrations of 5.10, 3.73, and 3.70 mg/kg, respectively.
Phase II ESA www.scsengineers.com
12
Although arsenic was reported to exceed the DTSC RSL for commercial land use and select samples
exceed the Tier 1 SSL for soil that is exported, the levels reported were within typical background
concentration ranges. In an abstract presented by Department of Toxic Substances Control staff at
the 2008 Society of Toxicology Annual Meeting,8 it was reported that the upper-bound background
concentration for arsenic in southern California soil is 12 mg/kg. Therefore, the maximum reported
arsenic concentration of 5.10 mg/kg is below the upper-bound background concentration of 12
mg/kg established by the DTSC. Therefore, the reported arsenic concentrations in shallow soil at the
Site are within the range of typical background concentrations and do not appear to be indicative of
a release of arsenic.
Lead - One soil sample was reported to exceed the Tier 1 SSL for lead (sample SB1); it was collected
from the depth of approximately 0.5 feet within the southern portion of the western drainage
channel and reported with a lead concentration of 33.6 mg/kg.
The Client reported that it is not known whether soil export will be required during the grading
activities for the proposed project. If soil export is proposed for the Site, it is recommended that the
soil proposed for export be tested for lead so that the soil can be characterized for proper disposal.
Zinc - One soil sample was reported to exceed the Tier 1 SSL for zinc (sample SB1); it was collected
from the depth of approximately 0.5 feet within the southern portion of the western drainage
channel and reported with a zinc concentration of 170 mg/kg.
The Client reported that it is not known whether soil export will be required during the grading
activities for the proposed project. If soil export is proposed for the Site, it is recommended that the
soil proposed for export be tested for zinc so that the soil can be characterized for proper disposal.
Comparison of Metals Concentrations to Risk-Based Mitigation Criteria (i.e., for
Soil that Remains on-Site)
Regarding the comparison of metals to Risk-Based Mitigation Criteria, with the exception of arsenic,
the reported metals concentrations are below applicable residential human health risk-screening
criteria (i.e., DTSC HERO HHRA Note Number 3, June 2020, and EPA RSLs, May 2021).
For the metal arsenic, concentrations were reported above the DTSC RSL for arsenic of 0.36 mg/kg
in all three of the soil samples analyzed for arsenic. Although arsenic was reported to exceed the
commercial/industrial DTSC RSL, the levels reported were below the DTSC upper-bound background
concentration for arsenic in southern California soil of 12 mg/kg. Therefore, the maximum reported
arsenic concentration of 5.10 mg/kg is below the upper-bound background concentration of 12
mg/kg established by the DTSC. Therefore, the reported arsenic concentrations in shallow soil at the
Site are within the range of typical background concentrations and do not appear to be indicative of
a release of arsenic.
Total Petroleum Hydrocarbons (TPH)
Soil analytical results for TPH were compared to Waste Based Mitigation-Criteria (i.e., Tier 1 SSLs)
and Health Risk-Based Mitigation Criteria (i.e., SFBRWQCB ESLs) as summarized in the table below.

Regarding waste-based screening criteria, detectable concentrations of chemical constituents such
as TPH would be considered a regulated waste if exported from the Site per the RWQCB Tier 1 SSLs.
A total of five of the eight soil samples (samples SB1, SB2, SB4-0.5, SB7-0.5, and SB8-0.5) analyzed
for TPH were reported with detectable concentrations of TPH; soil represented by these samples
would be considered a regulated waste if exported from the Site.

soil is not considered to represent a human health risk to future commercial/industrial users of the
Site, and can be freely graded on-Site during proposed grading activities.

A total of three of the five soil samples (samples SB4-0.5, SB7-0.5, and SB8-0.5) analyzed for PAHs
were reported with detectable concentrations of PAHs; soil represented by these samples would be
considered a regulated waste if exported from the Site.

Comparison of PAH Concentrations to Risk-Based Mitigation Criteria (i.e., for Soil
that Remains on-Site)
PAHs were not detected above the Health Risk-Based Mitigation in any of the five soil samples
collected and analyzed. Therefore, based on the soil samples collected and analyzed for PAHs, the
soil is not considered to represent a human health risk to future commercial/industrial users of the
Site, and can be freely graded on-Site during grading activities.
5 CONCLUSIONS
Based on the samples collected as part of this Phase II Environmental Site Assessment (ESA),
laboratory results, current regulatory guidelines, and SCS’ experience and professional judgment,
SCS concludes and recommends the following:
Background
• SCS performed a Phase II ESA consisting of the following:
o Advancement and sampling of three soil vapor probes (identified as SV1 through
SV3), and the collection of four soil vapor samples (including a replicate sample)
from depths ranging 2 to 4 feet below grade for analysis of volatile organic
compounds (VOCs), in order to assess possible impacts from the northern adjacent
industrial properties, and from some former totes previously situated adjacent to the
northeastern portion of the Site. Note that sample depths of 5 feet deep could not
be attained due to practical refusal encountered with a hand held roto-hammer, the
only sampling method considered feasible for the steep and rugged terrain at the
Site.
o Advancement of three soil borings using a trowel (borings SB1 through SB3) and five
soil borings by using a hand-held auger (borings SB4 through SB8) to total depths of
up to 2.0 feet below grade at the Site to assess the possible presence and
concentrations of constituents of concern (CoCs) (i.e., petroleum hydrocarbons, Title
22 metals, polycyclic aromatic hydrocarbons [PAHs], and volatile organic compounds
[VOCs]) within representative locations within the on-Site drainage channels, in
connection with possible impacts from the northern adjacent industrial properties.
Soil Vapor Investigation
• The VOCs carbon disulfide, toluene, m,p-xylene, o-xylene, 1,2,4-trimethylbenzene, and
chloroform were reported to be present in soil vapor beneath the Site.
o Carbon disulfide, toluene, m,p-xylene, o-xylene, and 1,2,4-trimethylbenzene are
typical constituents of petroleum hydrocarbons, likely from the nearby industrial
facilities or another off-Site source. Chloroform is a routine drinking water
disinfection byproduct (trihalomethanes) and is often present in soil and soil vapor
from treated tap water via irrigation or other sources of drinking water.
o Overall, based on the low concentrations at which they were detected, it’s unlikely
the VOCs in soil vapor resulted from a point source or significant release at the Site,
but more likely have migrated beneath the Site from the nearby industrial facilities
facility or another off-Site source.
Phase II ESA www.scsengineers.com
16
• Because VOCs were reported above the laboratory reporting limits in the soil vapor samples
collected from the Site, a vapor intrusion risk screening (VIRS) was conducted to assess the
potential for Significant vapor intrusion risk posed to the future commercial/industrial
occupants at the Site due to the upward migration of VOCs in soil vapor.
o After applying the Department of Toxic Substances Control (DTSC) attenuation factor
0.0005 for a future commercial/industrial land use to the maximum reported
concentrations of the constituents reported to be present beneath the Site (carbon
disulfide, toluene, m,p-xylene, o-xylene, 1,2,4-trimethylbenzene, and chloroform), the
maximum theoretical concentrations of VOCs in indoor air at the Site are below the
commercial/industrial screening levels (DTSC- Modified Screening Levels or EPA
Regional Screening Levels).
Soil Investigation
• Detectable concentrations of total petroleum hydrocarbons (TPH) and Polycyclic Aromatic
Hydrocarbons (PAHs) and somewhat elevated concentrations of the metals arsenic, lead,
and zinc were reported to be present in certain samples collected at the Site and exceed
Waste-Based Mitigation Criteria (i.e., Regional Water Quality Control Board [RWQCB] Tier 1
Soil Screening Levels [SSLs]). Reported concentrations of TPH include relatively low
concentrations in the diesel and oil carbon chain lengths. Reported concentrations of PAHs
include relatively low concentrations of benzo(a)anthracene, chrysene, fluoranthene,
phenanthrene, and pyrene, and would be considered a regulated waste, likely a non-
hazardous regulated waste, if this soil is exported from the Site. In the event that the soil is
exported from the Site, representative portions of the stockpiles to be exported should be
analyzed for TPH, Title 22 metals, and PAHs for proper waste characterization and disposal.
• With the possible exception of arsenic that is further described in the bullet below, none of
the reported TPH, PAHs, and metal concentrations were reported to exceed Health Risk-
Based Mitigation Criteria for commercial/industrial users established by the DTSC
(Recommended Screening Levels [RSLs]), San Francisco Bay Regional Water Quality Control
Board (Environmental Screening Levels), and US Environmental Protection Agency (RSLs), as
stipulated in the Report. Therefore, based on the soil samples collected and analyzed for
TPH, PAHs, VOCs, and Title 22 metals, the soil is not considered to represent a human health
risk to future commercial/industrial users of the Site, and can be freely graded on-Site during
grading activities.
• For the metal arsenic, concentrations were reported above the DTSC RSL for arsenic of 0.36
milligrams per kilogram (mg/kg) in all three of the soil samples analyzed for arsenic. Arsenic
was reported with a maximum concentration of 5.10 mg/kg at the Site. Although arsenic
concentrations at the Site reported to exceed the commercial/industrial DTSC RSL and the
Tier 1 SSL for arsenic, the levels reported were below the DTSC upper-bound background
concentration for arsenic in southern California soil of 12 mg/kg. Therefore, the maximum
reported arsenic concentration of 5.10 mg/kg is below the upper-bound background
concentration of 12 mg/kg established by the DTSC. Therefore, the reported arsenic
concentrations in shallow soil at the Site are within the range of typical background
concentrations and do not appear to be indicative of a release of arsenic.

6 RECOMMENDATIONS
Based on the data obtained during this Assessment and our conclusions, current regulatory
guidelines, and our experience and professional judgment, SCS recommends the following:
Soil Vapor Investigation
• No further action for the Site related to soil vapor intrusion at this time for the proposed
commercial/industrial land use.
Soil Investigation
• The Client reported that it is not known whether soil import will be required during the
grading activities for the proposed project. If soil export is proposed for the Site, it is
recommended that the soil proposed for export be tested for the identified CoCs for the Site
including TPH, PAHs, and Title 22 metals and so that the soil can be characterized for proper
disposal.

Notes:
Soil samples collected by SCS Engineers on 7/13/21.
Soil samples were analyzed for Title 22 metals by Environmental Protection Agency (EPA) Method 6010B.
mg/kg : milligrams per kilogram.
< : less than the laboratory reporting limit.
bgs : below ground surface
Bold : Result indicating above laboratory reporting limits.
1) Health Risk-Based Criteria - For lead, the Department of Toxic Substances Control (DTSC) Human and Ecological Risk Office (HERO) Human Health Risk Assessment (HHRA) Note Number: 3, June 2020, using the Recommended Screening
Levels (RSL) for commercial/ industrial soil and cancer endpoint, or, for other metals not listed in HHRA Note 3, the Regional Screening levels for commercial/industrial soil, provided by the EPA and updated as of November 2021 were used.
For arsenic, although the DTSC RSL is 0.11 mg/kg, naturally occuring arsenic typically exceeds human health risk screening criteria. Therefore, the DTSC upper-bound background concentration for arsenic of 12 mg/kg was used.
2) Hazardous Waste Criteria: Values shown from CA code of regulations, Title 22 Article 3, July 20, 2005 regarding characteristics of hazardous waste. Exceedances of the Total Threshold Limit Concentration (TTLC) would be considered a California hazardous waste, at a minimum.
