PHASE II ENVIRONMENTAL SITE

ASSESSMENT

FORMER CALIFORNIA COMPRESS FACILITY
2740 WEST NIELSON AVENUE

FRESNO, CALIFORNIA

1.0 EXECUTIVE SUMMARY

Salem Engineering Group, Inc. (SALEM) performed a Phase II Environmental Site Assessment (ESA) to investigate the Former California Compress Facility property located at 2740 West Nielson Avenue in Fresno, California (subject property). The subject property comprises an approximately 44.95-acre rectangular-shaped subject property and consists of two parcels (Fresno County Assessor’s Parcel Numbers [APNs] 458-020-71 and 458- 020-72). The investigation was performed in accordance with SALEM’s Proposal No. P1-420-1899 dated December 15, 2020.

During the course of SALEM’s January 29, 2021 Phase I ESA, SALEM identified the following evidence of Recognized Environmental Conditions (RECs) in connection with the subject property as defined by ASTM E1527-13:

• At least three known septic systems were associated with the former structures on the subject property, two of which were visually identified during SALEM’s November 19, 2020 site reconnaissance as remaining at the subject property. The former septic systems may have acted as a conduit for c ontaminants to enter on- site soil from potential past unauthorized disposal of hazardous substances and/or petroleum products utilized for vehicle maintenance into drains, sinks and toilets. SALEM recommended conducting a Limited Soil Assessment (LSA) in the vicinity of the septic systems to determine if on-site soils have been impacted by unauthorized releases of the constituents of concern into the septic systems.

• Historic operations at the subject property included the handling and storage of cotton which required an extensive fire suppression system. Two water basins were historically located in the southern portion of the subject property. SALEM personnel located more than 25 features across the subject property indicative of a fire suppression system including stand pipes, traffic bollards, and fire hydrants. The system reportedly included diesel -powered water pumps supplied from an aboveground storage tank (AST) historically located in the south- central portion of the subject property. The former dies el AST location was identifiable by concrete footings and a fire extinguisher. Additional concrete footings indicative of propane ASTs were observed in the north- central portion of the subject property. No staining or signs of leakage were observed in the vicinity of the former ASTs. However, SALEM recommended conducting a LSA to assess on-site shallow soils for potential petroleum hydrocarbon impacts in the vicinity of the former diesel AST.

• A soil mound was observed in the southern portion of the subject property and was reported to have been excavation dirt and asphalt produced when the floor of a warehouse was switched from asphalt to concrete to accommodate heavy machinery. No obvious visual evidence of hazardous substances and/or petroleum products or staining was observed on the surface of the stockpile. Based upon the absence of documentation regarding the source of the s tockpiled soil, SALEM recommended Project No. 1-420-1016
February 3, 2021

collecting samples of the stockpiled soil in or der to determine if the soil had been impacted by constituents of concern prior to either transporting the soil off-site for disposal or utilizing the soil on-site as clean-fill if needed during the redevelopment of the subject property.

The following Historical Recognized Environmental Condition (HREC) was identified:

• The former California Compress facility operated four underground storage tanks (USTs) consisting of a 10,000-gallon fuel oil UST historically located on what is now the north adjacent property; a 4,000-gallon double-walled steel diesel UST; a 4,000-gallon single-walled steel diesel UST; and a 1,000-gallon single-walled steel regular unleaded gasoline UST historically located in the southwest portion of the subject property. Records indicate all UST were properly permitted and removed under the regulatory agency oversight of Fresno County Environmental Health Division (FCEHD). A record of a “Hazardous Material Release” was recorded on June 5, 1995 indicating soil contamination from petroleum products discovered during removal of a UST.

California Regional Water Quality Control Board (RWQCB) records indicate that FCEHD issued a “case closed” designation for the California Compress leaking underground storage tank (LUST) site on July 3, 1996.

Scannell Properties requested that SALEM perform a Phase II ESA to address the RECs and HREC identified in SALEM’s January 29, 2021 Phase I ESA, to gather data regarding current site conditions, to establish baseline soil and soil vapor concentrations, and to evaluate if soil vapor conditions pose a potential vapor intrusion risk to future occupants at the subject property.

The following data summary is based on a review of field and laboratory data obtained during SALEM’s investigation at the subject property:

• According to RWQCB records for the Fresno Drum, Eastern Parcel facility, located at 733 South Hughes Avenue, approximately 0.65-mile south of the subject property, groundwater in the vicinity of the subject property was reported at a depth of approximately 65 to 80 feet below ground surface (bgs) with a general direction of flow toward the northeast. However, local groundwater level and flow direction may vary due to seasonal fluctuations in precipitation, usage demands, geology, and/or surface topography. Groundwater was not encountered during the course of this investigation.

• A geophysical survey was conducted on January 4, 2021 which identified the suspected former UST pit. The pit displayed a different soil density compared to the surrounding areas and the surface area of this location displayed patched/cut concrete and asphalt. Additionally, two of the three suspected septic systems were positively identified. No other anomalies indicative of potential buried fuel USTs and associated appurtenances, additional backfilled UST cavities, or other sub- grade structures of environmental concern (hoists, clarifiers, and sumps) were identified during the performance of the geophysical survey.

• SALEM installed eight soil borings (SV-1 through SV-6, SB-7, and SB-8) to depths ranging from 10 to 15 feet bgs. Borings SV-1 through SV-6 were converted to dual-completion soil vapor sample points with probes at 5 and 10 feet bgs. Borings SV-1, SV-3, and SV-6 were located near the former and suspect septic tank locations ; SV-2 and SB -7 were locate d near the former UST pit in the southwest portion of the subject property; SV-4 and SV-5 were located near the former diesel and propane AST locations, respectively; and S B-8 was located adjacent to a ring of traffic bollards historically associated with the fire suppression system in the south portion of the subject property.

Project No. 1-420-1016

• Generally, soil types consisted of light brown, well sorted, medium- to fine-grained sand (SP) sand to approximately 10 feet bgs, underlain by brown silt with sparse very fine-grained sand (ML) to the maximum depth drilled of 15 feet bgs. Drilling refusal was met at a depth of 7 feet bgs at location SB-8 near the fire suppression equipment in the south portion of the subject property . A subsurface manmade feature is the suspected cause; however, due to the absence of apparent contamination the area was not investigated further.

• Total petroleum hydrocarbons (TPH) were identified above laboratory method detection limits in 16 of the 18 soil samples analyzed. TPH as diesel (TPHd, carbon range C10-C24) was identified at concentrations ranging from 6.6 milligrams per kilogram (mg/kg) to 24 mg/kg. Additional TPH detected was consistent with mostly oil range hydrocarbons (TPHo) at concentrations ranging from

5.8 mg/kg to 360 mg/kg. TPH concentrations were below their respective established San Francisco Regional Water Quality Control Board (RWQCB -SF) Commercial/Industrial Environmental Screening Levels (ESLs) set at 260 mg/kg for TPHd and 1,600 mg/kg for TPHo.

• Volatile organic compounds (VOCs) and polychlorinated biphenyls (PCB s) were not identified above laboratory method detection limits in any of the soil samples analyzed. Data suggests that VOCs and PCBs are not constituents of potential concern (COPCs) in soil at the subject property.

• Semi-volatile organic compounds (SVOCs) detected in the composite soil samples collected from the soil stockpile located in the south portion of the subject property consisted of benzo(a)anthracene (0.41 to 0.49 mg/kg), chrysene (0.38 mg/kg), fluoranthene (0.49 mg/kg), phenanthrene (0.57 mg/kg), and pyrene (1.3 mg/kg). All detected concentrations of SVOCs were below their respective RWQCB-SF Commercial/Industrial ESLs.

• Arsenic was detected in soil samples collected at 5 feet bgs in SV-4 (11 mg/kg), SB-7 (14 mg/kg), and SB-8 (45 mg/kg). These values exceed the RWQCB-SF Commercial/Industrial ESL set at 0.31 mg/kg for cancer risk and appear to be slightly elevated in comparison to arsenic concentrations in Fresno County (1.8 to 6.0 mg/kg) and to regional arsenic concentrations in the San Joaquin Valley (Wilson, et al, 1990) that range from 0.8 to 20 mg/kg.

• Additional Title 22 metals detected included barium, cobalt, chromium, copper, nickel, lead, vanadium, and zinc at concentrations below their respective established RWQCB-SF Commercial/Industrial ESLs. No other Title 22/CAM 17 metals were detected above laboratory detection limits.

• VOCs were not identified above laboratory method detection limits in any of the soil vapor samples.

Based on these results, SALEM believes that no additional assessment activities are required. The subject property is suitable for unrestricted use and no engineering controls (i.e. VOC vapor barrier) are required. In the event the subject property will undergo any redevelopment which would include soil disturbance, SALEM recommends that a Soil Management Plan (SMP) be prepared to address soil management procedures that may arise based on historical use of the subject property and the known TPH and arsenic impacts.

2.0 INTRODUCTION AND PROJECT OBJECTIVES

SALEM conducted a Phase II ESA on behalf of Scannell Properties to investigate the Former California Compress Facility property located at 2740 West Nielson Avenue in Fresno, California (subject property – see Figure 1). The investigation was performed in accordance with SALEM’s Proposal No. P1-420-1899 dated December 15, 2020.

Project No. 1-420-1016
February 3, 2021
Page No. 4

The subject property comprises an approximately 44.95- acre rectangular -shaped subject property that consists of two parcels (Fresno County APNs 458-020-71 and 458-020-72), at 2740 West Nielsen Avenue, located on the north side of West Nielsen Avenue between North Marks Avenue and South Hughes Avenue in Fresno, California.

SALEM’s January 29, 2021 Phase I ESA identified the following evidence of RECs in connection with the subject property as defined by ASTM E1527-13:

• At least three known septic systems were associated with the former structures on the subject property, two of which were visually identified during SALEM’s November 19, 2020 site reconnaissance as remaining at the subject property. The former septic systems may have acted as a conduit for contaminants to enter on- site soi l from potential past unauthorized disposal of hazardous substances and/or petroleum products utilized for vehicle maintenance into drains, sinks and toilets. SALEM recommended conducting an LSA in the vicinity of the septic systems to determine if on-site soils have been impacted by unauthorized releases of the COPCs into the septic systems.

• Historic operations at the subject property included the handling and storage of cotton which required an extensive fire suppression system. Two water basins were his torically located in the southern portion of the subject property. SALEM personnel located more than 25 features across the subject property indicative of a fire suppression system including stand pipes, traffic bollards, and fire hydrants. The system repo rtedly included diesel-powered water pumps supplied from an AST historically located in the south-central portion of the subject property. The former diesel AST location was identifiable by concrete footings and a fire extinguisher. Additional concrete footings indicative of propane ASTs were observed in the north-central portion of the subject property. No staining or signs of leakage were observed in the vicinity of the former ASTs. However, SALEM recommended conducting a n LSA to assess on -site shallow so ils for potential petroleum hydrocarbon impacts in the vicinity of the former diesel AST.

• A soil mound was observed in the southern portion of the subject property and was reported to have been excavation dirt and asphalt produced when the floor of a warehouse was switched from asphalt to concrete to accommodate heavy machinery. No obvious visual evidence of hazardous substances and/or petroleum products or staining was observed on the surface of the stockpile. Based upon the absence of documentation regar ding the source of the stockpiled soil, SALE M recommended collecting samples of the stockpiled soil in or der to determine if the soil had been impacted by constituents of concern prior to either transporting the soil off-site for disposal or utilizing the soil on-site as clean-fill if needed during the redevelopment of the subject property.

The following HREC was identified:

• The former California Compress facility operated four USTs consisting of a 10,000-gallon fuel oil UST historically located on what is now the north adjacent property; a 4,000-gallon double-walled steel diesel UST; a 4,000-gallon single-walled steel diesel UST; and a 1,000-gallon single-walled steel regular unleaded gasoline UST historically located in the southwest portion of the subject property. Records indicate all UST s were properly permitted and removed under the regulatory agency oversight of FCEHD. A record of a “Hazardous Material Release” was recorded on June 5, 1995 indicating soil contamination from petroleum products discovered during removal of a UST.

RWQCB records indicate that FCEHD issued a “case closed” designation for the California Compress LUST site on July 3, 1996.

Project No. 1-420-1016
February 3, 2021
Page No. 5

SALEM recommended conducting a Phase II ESA to determine if the subject property has been negatively impacted by the historical facility operations, if soil vapor conditions pose a potential vapor intrusion risk to future occupants at the subject property, and to evaluate p otential construction concerns (vapor barrier engineering, design, and installation and off -haul of potentially -contaminated soils) associated with the redevelopment process. In addition, SALEM recommended conducting a geophysical survey at the subject property to confirm the presence or absence of sub -grade structures of environmental concern, including the USTs associated with the former site operations.

3.0 SCOPE OF WORK

The Phase II ESA scope of services included the following:
• Coordination of pre-field activities including procurement of any necessary permits, evaluation of groundwater data, and access permission;
• Development of a site-specific Health and Safety Plan (HSP); • Performance of private subsurface utility screening;
• Advancement of eight soil borings (SV-1 through SV-6, SB-7, and SB-8) to depths ranging from 10 to 15 feet bgs, with the collection of soil samples at 5-foot intervals from each boring; • Installation of vapor probes at depths of 5 and 10 feet bgs in borings SV-1 through SV-6; • Collection of twelve primary and one duplicate soil vapor sample; • Analytical testing of soil and soil vapor; and
• Preparation of a report that documents field activities, analytical results, and summarizes the findings.

3.1 Pre Field Activities

3.1.1 Site Safety
SALEM completed a Site HSP for the work proposed at the subject property. A copy of the HSP was kept on-site during field activities. The HSP detailed the work to be performed, safety precautions, emergency response procedures, nearest hospital information, hospital route maps, emergency contact numbers, and onsite personnel responsible for managing emergency situations (intended to protect on- site workers and the public).

3.1.2 Permits
Permits for the soil borings were not required for this scope of work.

3.1.3 Utility Clearance and Geophysical Survey
The proposed soil boring locations were marked with white paint and Underground Service Alert (USA) was notified at least 48 hours befo re beginning field activities. USA notified its subscribed members, requesting them to mark their underground utility locations near marked boring locations as required by California State law.

On January 4, 2021 SALEM utilized GPRS of Modesto, California to conduct a private utility survey and locate potential buried fuel USTs of 500 -gallon capacity or greater and associated appurtenances, or a backfilled UST cavity, as well as other sub-grade structures of environmental concern (hoists, clarifiers, and sumps). GPRS employed electromagnetic magnetic induction (EMI) and ground penetrating radar (GPR) investigation methods. The surface trace of detected features was marked on the ground with spray paint.

4.0 SOIL AND SOIL VAPOR INVESTIGATION METHODOLOGY

Field work for the soil sampling, nested vapor well installation, and soil vapor sampling was performed on January 7-8, 2021. Soil boring and vapor probe locations are shown on Figure 2.

Before arriving at the subject property, the drill rig, tools, and accessories were thoroughly decontaminated with a steam cleaner. Downhole drilling tools and sampling equipment, such as bits, rods, and sample barrels were manually washed/rinsed, pressure washed, and/or steam cleaned between borings and sample intervals at the designated decontamination area.

4.1 Soil Sampling and Soil Vapor Probe Installation Procedures SALEM installed eight soil borings to depths ranging from 10 to 15 feet bgs depending on the feature being investigated. Borings SV-1, SV-3, and SV-6 were located near the former and suspect septic tank locations; SV-2 and SB-7 were located near the former UST pit in the southwest portion of the subject property; SV- 4 and SV-5 were located near the former diesel and propane A ST locations, respectively; and S B-8 was located adjacent to a ring of traffic bollards historically associated with the fire suppression system in the south portion of the subject property. The borings were advanced using an AMS Powerprobe TM direct-push
rig operated by TEG of Northern California of Rancho Cordova, California. A 4-foot long Long-Bore Soil Sampler, lined with acetate sleeves, was attached to the bottom of the drive rod. Soil samples were continuously collected at each boring location and retained at 5- foot intervals for laboratory analysis . At each sample interval, the sampler was retrieved , and the acetate sleeve was removed. A portion of the acetate sleeve was cut away from the soil core, capped with Teflon sheets and rubber end caps, and labelled with the sample name, sample date and time, and sampler’s initials. The samples were recorded on a chain- of-custody document, sealed in a zip- lock bag, and placed in cold storage pending submitt al to Sierra Analytical Laboratory of Laguna Hills, California, for chemical analysis. A description of the soil was recorded on field boring logs in general accordance with the Unified Soil Classification System (USCS).

Two soil samples from each boring location were analyzed for total petroleum hydrocarbons – carbon range analysis (TPH-CRA), VOCs and fuel oxygenates, and Title 22 metals using EPA Methods 8015B, 8260B, and 6010B/7471A, respectively.

Additionally, eight surface soil samples from the soil and asphalt debris stockpile located near the southern boundary of the subject property w ere collected and composited into two soil samples (SS-1 and SS -2).

Each composite soil sample was analyzed for TPH-CRA, VOCs, Title 22 metals, PCBs, and SVOCs using EPA Methods 8015B, 8260B, 6010B/7471A, 8082A, and 8270C, respectively.

Soil analytical results are summarized in Tables 1 and 2. Laboratory analytical results and chain-of-custody documentation are provided in Appendix A.

Borings SV-1 through SV -6 were converted into dual-completion soil vapor sample points. Nested soil vapor probes were installed at depths of 5 and 10 feet bgs in each soil vapor sample location. A 1/8-inch diameter Nylaflow tube, attached to a sample port, was inserted into the open boring and set approximately 3 inches off the bottom. Number 3 washed aquarium sand was poured into the borehole until the sand extended from approximately 3 inches below and 3 inches above the slotted portion of the tube.

Approximately 6 inches of fine bentonite crumble was placed in the hole as an annular seal and hydrated with water. Additional bentonite crumble was alternately placed in the hole and hydrated in intervals, to the ground surface. Each Nylaflow tube was labeled with the sample point identification and sample depth.

Project No. 1-420-1016
February 3, 2021
Page No. 7

4.2 Soil Vapor Sampling
Soil vapor samples w ere collected from the soil vapor probes on January 7, 2021 by SALEM personnel.

Soil vapor sample procedures were completed in accordance with the July 2015 Advisory, Active Soil Gas Investigations, published jointly by the Department of Toxic Substances Control ( DTSC), California Environmental Protection Agency (Cal EPA), and the Los Angeles and San Francisco Regional Water Quality Control Boards.

4.2.1 Shut-in Testing
Before purging and sampling of the soil vapor probes, a shut-in test was conducted on the sampling train to check for leaks in the above-ground fittings. The shut-in test was conducted by attaching the complete sample train assembly to the termination valve on the soil vapor probe. With the valve attached to the soil vapor probe in the “off” position, a plastic syringe was used to evacuate the sample train of air to a minimum measured vacuum of approximately 100 inches of water. The vacuum was observed using an in- line vacuum gauge which was positioned before the purge point. The vacuum gauge was observed for approximately 1 minute and all above ground connections were considered “air -tight” when the pressure on the gauge did not noticeably dissipate. Sampling did not commence until the above-ground fittings were deemed air-tight.

4.2.2 Leak Testing
Leak testing, using a liquid tracer, was performed on each individual soil vapor probe in order to test the integrity of the entire sampling system. Its purpose was to evaluate whether an adequate seal was established at the soil vapor probe interface with the ground surface, as well as a leak check of all above ground fittings to ensure that the samples collected are not being diluted by ambient air. The leak check compound isopropyl alcohol was used to evaluate sample integrity. The leak check compound was applied to a paper towel and kept in a closed plastic zip closure bag until it was ready to be used.

Before purging and sampling of the soil vapor probe, the zip closure bag was opened and placed directly at the point of entry of the soil vapor probe into the borehole. Additional saturated towels were also placed near the above-ground sample train connections to ensure there were no leaks in the fittings.

4.2.3 Soil Vapor Sample Collection and Analysis
A plastic syringe was used to purge each probe. The syringe was attached to a 3-way valve, which was then connected to the on/off valve on the soil vapor probe. This 3-way valve allows the sample train to be connected to one port on the valve, and the purge equipment to be attached to the other. This ensured that all of the sample train assembly being used for the collection of the sample was upstream of the purging device. Three purge volumes (calculated to include the sand pack, dry bentonite, and vapor tubing volume) were removed from probes that were able to provide a vapor response to ensure that ambient air from the sampling system was removed, and to demonstrate that samples collected were representative of subsurface conditions.

SALEM personnel practiced careful monitoring of purge volumes and flow rates. An air-tight 3-way valve was attached to the syringe that allowed the purge air to be drawn into the system and then evacuated out the syringe’s side port. The syringe was attached to an in-line vacuum gauge so that probe vacuum could be monitored as the syringe drew in the purge vapor. The in-line vacuum gauge ensured that probe vacuum pressures were less than 100 inches of water during purging . During purging, the flow rate was timed so that it did not exceed 200 milliliters per minute. Please note that the syringe was used only for purging the soil vapor probes and was not used in the collection of the soil vapor samples.

Soil vapor samples were collected using appropriate gas-tight containers required for the specified analyses.

The sample collection assemblies and containers were attached to the soil vapor probe via a 3 -way valve before purging the device to avoid cross -contamination. SALEM utilized airtight calibrated Summa Project No. 1-420-1016
February 3, 2021
Page No. 8

canisters to collect vapor samples from each probe. The Summa canister was attached via a luer lock connection to a 3-way valve, which allowed the sample to be drawn into the canister and then sealed off by rotating the valve. The canister was attached to the 3 -way valve connected to the soil vapor probe on/off valve, and before the purging device. After purging of the soil vapor probe was complete, the valve was rotated so that the flow path of the soil vapor probe was di verted to the Summa canister. The valve on the Summa canister was opened slowly to allow the soil vapor to flow into the canister at a rate of 200 milliliters per minute or less. When the Summa canister was full, as indicated by a negative pressure gauge, the valve on the canister was closed and the canister was then disconnected and immediately placed into a storage container to prevent photo-degradation of the target analytes from direct sunlight.

For each sample, the sample name, date, and time of coll ection, vapor flow information and results of QA/QC inspections were recorded on field data sheets. Sample name, date, and time were recorded on a chain-of-custody document and transferred to the stationary laboratory for analysis.

Upon submittal to H&P’s analytical laboratory, the samples were injected into a gas chromatograph/mass spectrometer (GC/MS) and analyzed for VOCs and fuel oxygenates using EPA Method 8260SV.

5.0 FINDINGS

5.1 Geology and Hydrogeology
The subject property is located within the San Joaquin Valley. The San Joaquin Valley, which includes the Fresno area, is a topographic and structural basin that is bounded on the east by the Sierra Nevada and on the west by the Coast Ranges. The Sierra Nevada, a fault block dipping gently southwestward, is composed of igneous and metamorphic rocks of pre -Tertiary age that form the basement complex beneath the San Joaquin Valley. The Coast Ranges contain folded and faulted sedimentary rocks of Mesozoic and Cenozoic age, which are similar to those rocks that underlie the Valley at depth and non -conformably overlie the basement complex; gently dipping to nearly horizontal sedimentary rocks of Tertiary and Quaternary age overlie the older rocks. These younger rocks are mostly of continental origin and in the Fresno area they were derived from the Sierra Nevada. The Coast Ranges evolved as a result of folding, faulting and accretion of diverse geologic terrains. They are broken by numerous faults, the San Andreas Fault being the most notable feature.

The San Joaquin Valley represents the southern portion of the Central Valley of California, also referred to as the Great Valley geomorphic province. The most extensive geomorphic units in the province include dissected uplands, low alluvial plains and fans, river floodplains and channels, and overflow lands and lake bottoms. The valley represents the alluvial, flood, and delta plains of two major rivers (the Sacramento and San Joaquin rivers) and their tributaries. The high alluvial fans are the largest geomorphic features in the Fresno area. These fans lie from 10 to 90 feet above the channels of the present day rivers and are not subject to inundation by the rivers. The Merced area alluvial fans form part of a continuum of fans along the eastern margin of the San Joaquin Valley structural trough. The sediments are derived from the Sierra Project No. 1-420-1016

Nevada to the east — most of the sediment is of probable glacial origin. The east side fans are formed by meandering or braided stream floodplain processes that contain more well-sorted, fine-grained material and have gentler slopes than the semiarid fans on the west side of the San Joaquin Valley. The east si de fans have low relief with very gentle gradients.

According to RWQCB records for the Fresno Drum, Eastern Parcel facility, located at 733 South Hughes Avenue, approximately 0.65-mile south of the subject property, groundwater in the vicinity of the subj ect property was reported at a depth of approximately 65 to 80 feet bgs with a general direction of flow toward the northeast. However, local groundwater level and flow direction may vary due to seasonal fluctuations in precipitation, usage demands, geology, and/or surface topography.

5.2 Field Observations
At the time of SALEM’s January 2021 Phase II ESA, the subject property observed to be vacant land mostly covered in asphalt and concrete with areas of grass and remnants of former landscaping.

Exposed surface soils did not exhibit obvious signs of discoloration at the subject property. No additional obvious evidence (fill pipes, dispensers, etc.) of USTs was noted within the area observed. No standing water or major depressions were observed on the subject property. Two areas exhibited patched/cut concrete and asphalt.

The geophysical survey conducted on January 4, 202 1 identified the suspected former UST pit. The pit displayed a different soil density compared to the surrounding areas and the surface area of this location displayed patched/cut concrete and asphalt. Additionally, two of the three suspected septic systems were positively identified. No other anomalies indicative of potential buried fuel USTs a nd associated appurtenances, additional backfilled UST cavities, or other sub-grade structures of environmental concern (hoists, clarifiers, and sumps) were identified during the performance of the geophysical survey.

Soil boring locations are shown on Fi gure 2. Generally, soil types consisted of light brown, well sorted, medium- to fine-grained sand (SP) to approximately 10 feet bgs, underlain by brown silt with sparse very fine-grained sand (ML) to the maximum depth drilled of 15 feet bgs. Drilling refusal was met at a depth of 7 feet bgs at location SB-8 near the fire suppression equipment in the south portion of the subject property, a subsurface manmade feature is the suspected cause; however, due to the absence of apparent contamination the area was not investigated further.

5.3 Analytical Results
Soil analytical results are summarized in Tables 1 and 2, and soil vapor analytical results are summarized in Table 3. Copies of the laboratory reports and chain-of-custody documentation are included in Appendix A.

5.3.1 Soil Analytical Results
Laboratory analytical results for soil were as follows:

5.3.2 Soil Vapor Analytical Results
Laboratory analytical results for soil vapor were as follows:

• VOCs were not identified above laboratory method detection limits in soil vapor samples. • The sampling tracer compound isopropyl alcohol was not detected above laboratory method detection limits in any of the samples.

6.0 CONCLUSIONS AND RECOMMENDATIONS

The following data summary is based on a review of field and laboratory data obtained during SALEM’s January 7 and 8, 2020 investigation at the subject property:

• According to RWQCB records for the Fresno Drum, Eastern Parcel facility, located at 733 South Hughes Avenue, approximately 0.65-mile south of the subject property, groundwater in the vicinity of the subject property was reported at a depth of approximately 65 to 80 feet bgs with a general direction of flow toward the northeast. However, local groundwater level and flow direction may vary due to seasonal fluctuations in precipitation, usage demands, geology, and/or surface topography. Groundwater was not encountered during the course of this investigation.

• A geophysical survey was conducted on January 4, 2021 which identified the suspected former UST pit. The pit displayed a different soil density compared to the surrounding areas and the surface area of this location displayed patched/cut concrete and asphalt. Additionally, two of the three suspected septic systems were positively ident ified. No other anomalies indicative of potential buried fuel USTs and associated appurtenances, additional backfilled UST cavities, or other sub - grade structures of environmental concern (hoists, clarifiers, and sumps) were identified during the performance of the geophysical survey.

• SALEM installed eight soil borings (SV-1 through SV-6, SB-7, and SB-8) to depths ranging from 10 to 15 feet bgs. Borings SV -1 through SV-6 were completed converted to dual-completion soil vapor sample points with probes at 5 and 10 feet bgs. Borings SV-1, SV-3, and SV-6 were located near the former and suspect septic tank locations; SV-2 and SB-7 were located near the former UST pit in the southwest portion of the subject property ; SV-4 and SV-5 were located near the former diesel and propane AST locations, respectively; and SB-8 was located adjacent to a ring of traffic bollards historically associated with the fire suppression system in the south portion of the subject property.

• Generally, soil types consisted of light brown, well sorted, medium- to fine-grained sand (SP), to approximately 10 feet bgs, underlain by brown silt with sparse very fine-grained sand (ML) to the maximum depth drilled of 15 feet bgs. Drilling refusal was met at a depth of 7 feet bgs at location SB-8 near the fire suppression equipment in the south portion of the subject property, a subsurface manmade feature is the suspected cause; however, due to the absence of apparent contamination the area was not investigated further.

• TPH was identified above laboratory method detection limits in 16 of the 18 soil samples analyzed.

TPH as diesel (TPHd, carbon range C10- C24) was identified at concentrations ranging from 6.6 mg/kg to 24 mg/kg. Additional TPH detected was consistent with mostly oil range hydrocarbons (TPHo) at concentrations ranging from 5.8 mg/kg to 360 mg/kg. TPH concentrations were below their respective established RWQCB-SF Commercial/Industrial ESLs set at 260 mg/kg for TPHd and 1,600 mg/kg for TPHo.

• VOCs and PCBs were not identified above laboratory method detection limits in any of the soil samples analyzed. Data suggests that VOCs and PCBs are not COPCs in soil at the subject property.

• SVOCs detected in the composite soil samples collected from the soil stockpile located in the south portion of the subject property consisted of benzo(a)anthracene (0.41 to 0.49 mg/kg), chrysene (0.38 mg/kg), fluoranthene (0.49 mg/kg), phenanthrene (0.57 mg/kg), and pyrene 1.3 mg/kg). All detected concentrations of SVOCs were below their respective RWQCB-SF Commercial/Industrial ESLs.

• Arsenic was detected in soil samples collected at 5 feet bgs at SV-4 (11 mg/kg), SB-7 (14 mg/kg), and SB-8 (45 mg/kg). These values exceed the RWQCB-SF Commercial/Industrial ESL set at 0.31 mg/kg for cancer risk and appear to be slightly elevated in comparison to arsenic concentrations in Fresno County (1.8 to 6.0 mg/kg) and to regional arsenic concentrations in the San Joaquin Valley (Wilson, et al, 1990) that range from 0.8 to 20 mg/kg.

• Additional Title 22 metals detected included barium, cobalt, chromium, copper, nickel, lead, vanadium, and zinc at concentrations below their respective established RWQCB-SF Commercial/Industrial ESLs. No other Title 22/CAM 17 metals were detected above laboratory detection limits.

• VOCs were not identified above laboratory method detection limits in any of the soil vapor samples.

Based on these results, SALEM believes that no additional assessment activities are required. The subject property is suitable for unrestricted use and no engineering controls (i.e. VOC vapor barrier) are required.

In the event the subject property will undergo any redevelopment which would include soil disturbance, SALEM recommends that an SMP be prepared to address soil management procedures that may arise based on historical use of the subject property and the known TPH and arsenic impacts.
