The work was conducted at the request of Jaco Oil Company (Client) and not by the request of a regulatory agency, however, Mr. Malcom, hazardous materials specialist with the Bakersfield Fire Department (BFD) provided UST oversight removal and soil sampling activities. The work was conducted in accordance with specifications contained within the BFD’s Consolidated Underground Storage Tank (UST) Closure Procedure document. All work was conducted under the direct supervision of a professional California-licensed geologist. 2.0 SITE LOCATION AND DESCRIPTION The subject site is located on the northeast corner of Myrtle Street and Brundage Lane in Bakersfield, California (Figure 1). The subject site is associated with a street address of 2732 Brundage Lane, Bakersfield, California 93304. The subject site consists of one (1) rectangular-shaped parcel measuring 0.22 acres with the associated Kern County Assessor’s Parcel Numbers (APNs) 008-212-35. The subject site is located along a commercial/retail corridor of Brundage Lane. Surrounding land is occupied by residential developments to the north, commercial and retail developments to the east, Brundage lane, commercial and retail developments to the south, and Myrtle Street and commercial developments to the west. Presently, the subject site is developed with a convenience store (D&Q Liquors) located within the easternmost portion of the subject site with the remainder of the subject site paved with asphaltic concrete. The fuel storage and delivery system consisted of three (3) 12,000-gallon underground storage tanks (USTs), one (1) containing regular unleaded (Tank T-2), one (1) containing premium unleaded (Tank T-1) and one (1) containing diesel (Tank T-3) and formerly occupied the west-central portion of the subject site (Figure 2). Excavated soils during removal of the USTs were temporarily stockpiled to the north and south of the UST excavation. KV Project. 01321013 Page No. 2 Krazan-VEIR With Offices Serving the Western United States 01323001 – Report of Findings – Fastrip #2233 3.0 SCOPE OF WORK Pursuant to the scope of work outlined in Krazan-VIER’s January 16, 2023 Request for Proposal/Cost Estimate, Soil Sampling and Analysis, Fastrip #2233, 2732 Brundage Lane, Bakersfield, California 93304 and authorized January 17, 2022 by the Client, the following scope of work was conducted (please refer to Figure 2 – Site Plan for referenced locations): 3.1 General Activities A site-specific health and safety plan (HASP) was prepared, including the appropriate level of personal protection equipment (PPE) for Krazan-VEIR personnel, to cover on-site field activities. Site safety protocols, including appropriate level of PPE, were maintained as well as a proper exclusion zone around the work area. Industry standard methods and protocols for equipment decontamination; sample collection, storage, transport, hold times, and chain-of-custody; etc., were implemented as outlined in Krazan- VEIR’s standard operation procedures (SOPs). A copy of Krazan-VEIR’s SOPs is provided in Appendix A. Soil samples were submitted to a State-approved laboratory for the following constituents and their respective analytical test methods: o Total petroleum hydrocarbons – carbon chain (TPH-cc) by EPA Test Method 8015; o Benzene, toluene, ethylbenzene, and xylenes (BTEX), fuel oxygenates, and naphthalene by EPA Test Method 8260, and o Total lead by EPA Test Method 6010. 3.2 Field Observations On January 12, 2023, upon arrival, Jaco representatives had uncovered the three (3) USTs. All of the USTs were of single-wall steel construction. The soil excavated above and around the USTs was stockpiled in two (2) locations, one (1) to the north and one (1) to the south of the UST excavation. Dry ice was placed into the three (3) empty and rinsed USTs. Prior to the removal of each UST, a lower explosive limit (LEL) meter was placed within each UST to confirm the complete evacuation of volatile organic compounds. The soils present in the excavation consisted of fine-grained silty sand, silty sand/sandy silt or sandy silt. The bottoms of the USTs were measured at approximately 12 feet below ground surface (bgs). The USTs were removed by a truck-mounted crane and placed on a trailer and transported off-site to SA Recycling in Bakersfield, California. The USTs were observed to be in good condition with minor rust and no visible holes. A copy of the approved BFD UST removal permit, hazardous waste manifest, UST certification of destruction, weighmaster certificates, and hazardous waste tank closure certification are provided in Appendix B. KV Project. 01321013 Page No. 3 Krazan-VEIR With Offices Serving the Western United States 01323001 – Report of Findings – Fastrip #2233 3.3 Soil Sampling Activities 3.3.1 Stockpile Soil Sampling On January 12, 2023, Krazan-VEIR collected one (1) three (3)-part composite soil sample from the northern stockpile (ST-N-3PT Comp) and one (1) three (3)-part composite soil sample from the southern stockpile (ST-S-3PT Comp). The composite soil samples were collected to determine if the stockpiled soils would be suitable for reuse or require off haul and disposal. The two (2) composite soil samples were submitted for laboratory analysis for TPH-cc, BTEX, fuel oxygenates, naphthalene, and total lead. 3.3.2 Underground Storage Tank Discreet Soil Sampling On January 12, 2023, soil samples were collected from approximately two (2) and six (6) feet below the bottom of each end of the three (3) USTs (T1-W@14', T1-W@18', T1-E@14', T1-E@18', T2-W@14', T2- W@18', T2-E@14', T2-E@18', T3-W@14', T3-W@18', T3-E@14', T3-E@18' for a total of 12 soil samples. Two (2) soil samples (MPD-1@3.5' and MPD-1@7.5') were collected from approximately 3.5 and 7.5 feet beneath the former MPD. Two (2) soil samples (PP-1@2.5' and PP-1@6.0') were collected from beneath the product piping in a single location at approximately 2.5 and six (6) feet below the product piping. Lastly, two (2) samples were collected from three (3) locations (VP-1@3', VP-1@6', VP-2@3', VP-2@6', VP-3@3', and VP-3@6') at approximately three (3) and six (6) feet beneath the vapor piping run. All soil samples were submitted for laboratory analysis for TPH-cc, BTEX, fuel oxygenates, naphthalene, and total lead. 4.0 APPLICABLE REGULATORY AGENCY REFERENCES Krazan’s evaluation of the results and findings associated with the soil sampling included referencing the November 2007 (Revised February 2019 [Revision 2]) San Francisco Regional Water Quality Control Board’s (SFRWQCB) environmental screening levels (ESLs) referenced in the technical document titled, Screening for Environmental Concerns at Sites with Contaminated Soil and Groundwater. According to the RWQCB’s 2007 document, ESLs are considered to be conservative. Under most circumstances and within limits described by the RWQCB, the presence of a chemical in soil, soil vapor or groundwater at concentrations below the corresponding ESL (Residential Land Use, Commercial/Industrial Land Use and Any Land Use/Depth: Construction Worker), for the respective constituent can be assumed not to pose a significant, long-term (chronic) threat to human health and the environment. Additional evaluation will generally be necessary at sites where a chemical is present at concentrations above the corresponding ESL. Active remediation may or may not be required, however, depending on site-specific conditions and considerations. As stated by the RWQCB, the ESL document may be especially beneficial for use at sites with limited impacts, where the preparation of a formal environmental assessment may not be warranted or feasible due to time and cost constraints. KV Project. 01321013 Page No. 4 Krazan-VEIR With Offices Serving the Western United States 01323001 – Report of Findings – Fastrip #2233 5.0 REPORT OF FINDINGS 5.1 Stockpile Soil Sampling Analytical Results Please refer to Table I for a summary of the analytical results for the composite soil samples collected from the stockpiled soils. A copy of the analytical laboratory report is provided in Appendix C. Analytical results for the composite and discreet soil samples submitted for laboratory analysis for TPH-cc reported four (4) concentrations of gasoline-range petroleum hydrocarbons (GRO) ranging from 51 (T2-W@14') milligrams per kilogram (mg/kg) to 930 mg/kg (T3-W@18'), four (4) concentrations of diesel-range petroleum hydrocarbons (DRO) ranging from 43 mg/kg (T3-E@18') to 720 mg/kg (T2-W@18') and motor-oil range petroleum hydrocarbons (MORO) were reported as not detected (ND) at or above laboratory reporting limits (RLs). Two of the reported GRO concentrations exceed the Commercial/Industrial ESL for GRO of 200 mg/kg. No reported concentrations of DRO exceed the Commercial/Industrial ESL for DRO of 1,200 mg/kg. Analytical results for the composite and discreet soil samples submitted for laboratory analysis for BTEX reported various concentrations as shown on Table I, however, none of the reported concentrations exceed the Commercial/Industrial Land Use ESL for the respective constituent. Analytical results for the composite and discreet soil samples submitted for laboratory analysis for naphthalene reported seven (7) concentrations of ranging from 0.0074 mg/kg (T3-E@14') to 5.5 mg/kg (T2-W@18'), however, none of the reported concentrations exceed the Commercial/Industrial Land Use ESL for naphthalene of 580 mg/kg. Analytical results for the composite and discreet soil samples submitted for laboratory analysis for total lead were reported as ND at or above laboratory reporting limits with the exception of a reported concentration of 4.6 mg/kg (ST-N-3PT Comp), however the reported concentration does not exceed the Commercial/Industrial Land Use ESL for lead of 320 mg/kg. 6.0 CONCLUSIONS Based on the findings in the field and the laboratory analytical report for the discreet soil samples collected and analyzed from the subject site within the area assessed, evidence of a release was identified beneath the USTs to at least 18 feet bgs with the most significant impacts located beneath the west ends of Tank T-3 and Tank T-2. Analytical results of the composite soil samples indicate that the stockpiled soils are suitable for reuse, however, it is recommended that the stockpiled soils not be placed on residential properties or properties planned for residential use or potentially occupied by sensitive receptors (hospitals, nursing homes, daycare centers, etc.). KV Project. 01321013 Page No. 5 Krazan-VEIR With Offices Serving the Western United States 01323001 – Report of Findings – Fastrip #2233 7.0 LIMITATIONS This scope of work conducted at the subject site was not intended to characterize or define the extent of possible impact beneath the site; rather, this work was conducted to assess the presence or absence of significant concentrations of constituents of concern (COCs) associated with the removal of an automobile fuel storage and delivery system. The findings of this report were based upon the results of our field and laboratory investigations, along with the interpretation of subsurface conditions encountered during removal activities. Therefore, the data are accurate only to the degree implied by review of the data obtained and by professional interpretation. The excavation and soil sample locations were located in the field based on available maps. Therefore, the location of the soil samples should be considered accurate only to the degree implied by the methods used to locate them. Chemical testing was done by laboratories certified by the State of California Department of Health Services. The results of the chemical testing are accurate only to the degree of care of ensuring the testing accuracy and the representative nature of the soil samples obtained. This subsurface investigation of the subject site has been limited in scope. This type of assessment is undertaken with the calculated risk that the presence, full nature and extent of contamination would not be revealed by methods employed. Therefore, no warranty is given, either expressed or implied, that hazardous material contamination or buried structures which would not have been disclosed through this investigation do not exist at the subject site. Therefore, the data obtained are clear and accurate only to the degree implied by the sources and methods used.

Krazan-VEIR observes these SOPs to obtain consistent and reliable data and provide a safe work environment. STANDARD OPERATING PROCEDURES FOR SOIL SAMPLING  Field activities shall be performed under the supervision of a California registered geologist, certified professional engineer.  A site-specific health and safety plan (HASP) shall be prepared prior to the beginning of field activities. The HASP shall include the appropriate level of personal protection equipment (PPE) for Krazan-VEIR personnel, to cover on-site field activities and route to the nearest emergency medical center.  Prior to Subsurface soil sampling, Underground Service Alert (USA) shall be notified, as required by law, so their member utility companies may mark their facilities within pertinent public rights-of-way and utility easements prior to proceeding with any subsurface exploration and sampling program. Dependent on subject site conditions and proposed scope of work, limited geophysical survey (LGS) may be warranted.  In-situ soil samples shall be collected using a split-spoon soil sampler, hand-driven soil sampler or similar device. In most cases, the soil sampler shall be lined with laboratory-grade brass, stainless steel or acrylic sleeves to retain a soil sample for analytical laboratory analysis. Teflon tape and plastic end caps should immediately be placed on each end of the sleeve after sample collection. Split-spoon soil samples will be collected by lowering the sampler to the bottom of the soil boring. The split-spoon soil sampler is then driven into undisturbed soil by repeatedly dropping a 140-pound weight from a height of 30 inches to the desired final depth. The number of blows (blow counts) required to advance the soil sampler 18 inches shall be recorded on the soil boring log adjacent to the respective depth of the collected soil sample. This information will be used to calculate the penetration resistance of the soil and estimate the soil density. Occasionally, grab soil samples may be obtained pursuant to the project’s scope of work. Nitrile gloves should be worn before each sample collection to minimize cross contamination.  Soil boring logs shall be completed in the field during drilling operations, however, certain projects may not require the logging of soils, such as collecting shallow grab soil samples for agricultural sampling. The soils encountered shall be continuously examined and visually classified in accordance with the Unified Soil Classification System. Evidence of contamination, if any, shall be recorded on the soil boring logs.  Field screening utilizing a photoionization detector (PID) shall be conducted during drilling activities, as well as to evaluate soil samples for the presence/absence of volatile constituents of concern (COCs) during sample collection and the results shall be recorded on the soil boring logs. SOPs for using a PID are described under the heading: Standard Operating Procedures for Using a Photoionization Detector.  Typically, based on field screening, the soil samples from within a soil boring exhibiting the Krazan-VEIR Standard Operating Procedures Page No. 2 Krazan-VEIR With Offices Serving the Western United States Standard Operating Procedures.docx highest potential for contamination shall usually be submitted for laboratory analysis. Soil samples intended for chemical analyses shall be sealed with Teflon® tape and plastic end caps, labeled, placed in an iced chest, labeled on a chain-of-custody, and delivered to an analytical laboratory under chain-of-custody protocol. STANDARD OPERATING PROCEDURES FOR SAMPLE HANDLING AND CHAIN-OF- CUSTODY PROTOCOL  Collected sample labels shall include the following information: o Sampling date; o Sample identification/location; o Job number; and o Initials of sampling personnel.  Each sample container shall be immediately labeled subsequent to sample collection. Chain- of-custody protocol procedures shall be consistent with those described in the United States Environmental Protection Agency’s (EPAs), Test Methods for Evaluating Solid Waste, SW- 846, Third Edition, 1986. Groundwater and soil samples shall be maintained at approximately 4° Celsius. Upon arrival to a State-approved analytical laboratory, the samples shall be preserved for analysis according to the laboratory’s SOPs.  The Krazan-VEIR employee responsible for fieldwork oversight/project management shall transport or direct the transportation of the collected samples and chain-of-custody forms to the laboratory. A receiving clerk, or an authorized analyst, shall sign the chain-of-custody forms, present a duplicate copy to the Krazan-VEIR representative and transfer the collected samples to a laboratory analyst. The laboratory shall prepare a sample receiving review sheet documenting the condition of the collected samples upon arrival to the analytical laboratory. The laboratory manager retains possession of the chain-of-custody forms during analyzes of the samples. STANDARD OPERATING PROCEDURES FOR PHOTOIONIZATION DETECTOR (PID) USE The PID must be calibrated in accordance with the manufacture's recommendations prior to use in the field. The PID is utilized to monitor background concentrations of volatile organic vapors (VOCs) in the atmosphere, field screen soil samples and influent/effluent soil vapor concentrations. Volatile Organic Compounds (VOCS) in the Atmosphere  First, the background atmosphere concentrations are measured with a slow-sweeping motion in a location upwind and removed as far as possible from the source(s) of VOCs at the subject site and recorded. During drilling activities, PID monitoring is performed at regular intervals at the bore hole and in the breathing zone and recorded as units above background (AB) not parts-per-million (ppm) and compared to those VOC values listed in the HASP to protect human health and identify the presence of explosive environments. Field Screening Soil Samples Krazan-VEIR Standard Operating Procedures Page No. 3 Krazan-VEIR With Offices Serving the Western United States Standard Operating Procedures.docx  A soil sample is placed in a sealed glass, stainless steel container or plastic bag, agitated and placed in a warm atmosphere. After approximately 15 minutes or sufficient time for a percentage of the VOCs to escape from the soil, insert the PID probe tip into the container and record the measured VOC concentration in parts per million (ppm). The PID readings will fluctuate, however, the highest measured concentration shall be recorded on the soil boring log adjacent to the depth the respective soil sample was collected from. Influent/Effluent Soil Vapor Concentrations  Attach a small length of inert tubing (tubing) to the Tedlar bag. With the PID calibrated and operating, open the valve of the Tedlar bag, insert the other end of the tubing to the tip of the PID. The PID readings will fluctuate, however, the highest measured concentration shall be recorded on the SVE operation and maintenance log. STANDARD OPERATING PROCEDURES FOR EQUIPMENT DECONTAMINATION  Before, during and following drilling operations, drilling equipment shall be thoroughly cleaned using a hot water (steam) pressure washer (steam cleaned). Well casing, screen, end caps, and centralizers shall also be steam cleaned. Steam cleaning/decontamination condensate shall be containerized in DOT-approved 55-gallon drums or similar DOT- approved container and stored on the subject site property for later disposal. Decontamination water is typically characterized either by collecting a direct sample of the decontamination water or on the basis of the groundwater sample analytical results. Disposal will be the responsibility of the Client or Responsible Party.  Sampling equipment, tooling, measuring devices, or other equipment which will come into contact with contaminated soil, groundwater or any media being assessed shall be washed in a phosphate-free detergent and water solution and triple rinsed in clean water before reuse. The type of detergent used will depend upon project requirements. STANDARD OPERATING PROCEDURES FOR DECONTAMINATION RINSATE, PURGE WATER, SOIL CUTTINGS AND/OR INVESTIGATION DERIVED WASTE DISPOSAL  Decontamination rinsate, purge water, soil cuttings, and/or investigation-derived waste (IDW) generated during site investigation, drilling operations, groundwater monitoring, and/or sampling activities shall be either covered by plastic sheeting, placed in lined roll-on/roll-off dumpster(s) or containerized in DOT-approved drums/containers. Containers containing soil, rinsate and/or purge water shall be sealed for temporary storage on the subject site property. A label shall be placed on each container with the generator’s contact information, date(s) of accumulation, contents, type of waste, origin of the waste, and Krazan-VEIR’s contact information. Disposal of these wastes shall be the responsibility of the Client or Responsible Party. The Client or Responsible Party shall be informed that the waste must be disposed in accordance with applicable Federal, State and local regulations. Appendix B #3 1 Christopher David From:Richard H.
