TRUXTUN AVENUE BAKERSFIELD, CA 93305 661/395-1646 FAX 661/395-1616 1 1.0 INTRODUCTION This report presents the results associated with the removal of one 500-gallon underground storage tank (UST) conducted on August 9, 2021 by Advanced Environmental Concepts, Inc. (AEC) at 823 19th Street, Bakersfield California. The objective was to assess the soil for the presence of gasoline-range hydrocarbons following excavation and removal of the inferred 500-gallon gasoline UST (Figure 1). Tank removal procedures were performed in accordance with tank removal permit No. 21-0000379 under the supervision of Mr. Malcom Moore of the Bakersfield Fire Department (BFD). AEC supervised and conducted the removal of the UST and Crider Construction provided the excavation equipment and transported the UST to SA Recycling for offsite disposal. Also, AEC and Cole’s Environmental cleaned the tank interior and transported the rinseate to Bakersfield Transfer, Inc. Finally, Mr. Jonathan Buck, Professional Geologist with AEC collected the required soil samples. This report includes background information regarding existing site characteristics, local geology and hydrology, tank removal procedures, sample collection procedures, analytical results, and related conclusions and recommendations. Report appendices contain Figures and Site Photographs (Appendix A), Tank Destruction Certification (Appendix B), Dry Ice Receipt (Appendix C), BFD Permit (Appendix D), Laboratory Report and Chain-of-Custody Documents (Appendix E), and Uniform Hazardous Waste Manifest (Appendix F). 2.0 PROCEDURES The 500-gallon gasoline UST was sited at the southeast corner of the subject property near the alley that trends along the south boundary. The following UST removal services were conducted during the course of this project on behalf of RLSL Group, LLC: • Remove the asphalt surface over the UST; • Excavate the soil from the top and sides of the UST; • Clean the interior of the tank using a pressure washer, remove the rinseate into three 55- gallon drums; • Measure LEL and Oxygen within the interior of the tank using a recently calibrated meter; • Inert the tank prior to removal using solid Carbon Dioxide (dry ice); • Remove the tank from the excavation using the backhoe and transport to SA Recycling, a metal recycling facility; • Collect soil samples from beneath tank invert (the dispenser was adjacent to tank top); • Backfill and compact the excavation; • Summarize these procedures in the form of a "Tank Closure Report".

TRUXTUN AVENUE BAKERSFIELD, CA 93305 661/395-1646 FAX 661/395-1616 2 3.0 PHYSICAL CHARACTERISTICS 3.1 Site Description The subject property at 823 19th Street, Bakersfield, California is identified by Kern County Assessor’s Parcel Number (APN) 006-060-07 which comprises approximately 0.13-acres. The site is currently improved with an approximate 3,000-square foot building developed in the northern half of the subject parcel which is currently occupied by Pure Vanity Salon and Spa. The southern half of the parcel consists of an asphalt-paved open yard that is not currently being used and is overgrown with weeds. 3.2 Site Geology The subject property is located in the southeastern end of the San Joaquin Valley where the Sierra Nevada, Great Valley, and Coastal Range physiographic provinces meet. The southern end of the Sierra Nevada province is composed of a massive block of igneous and metamorphic rock of Mesozoic age and older. This Sierran block, 40 to 100 miles wide and 400 miles long, slopes five to seven degrees beneath the San Joaquin Valley. The Coastal Range province on the west consists of tectonically deformed and fractured marine and non-marine sedimentary rocks of Jurassic, Cretaceous, and Tertiary age which dip eastward beneath the San Joaquin Valley. The Great Valley province is a broad asymmetrical synclinal trough, which is known as the Sacramento Valley in the north and the San Joaquin Valley in the south. Beneath the southern San Joaquin Valley floor, the Sierran plutonic and metamorphic rock is overlain by consolidated marine rocks of Jurassic and Cretaceous age. These rocks are overlain by continental marine and non-marine sedimentary rocks of Tertiary age. These continental deposits are consolidated to semi-consolidated, fossilferous sandstone, siltstone, and shale which thicken toward the south and west. The Tertiary rocks are overlain by unconsolidated continental deposits consisting of Pliocene to Holocene river and lake sediments of gravel, sand, silt, and clay. Surface features of the floor of the San Joaquin Valley consist of dissected uplands, alluvial fans, overflow areas, and lake bottoms. Dissected uplands lie between the mountains and the nearly flat Valley floor and are manifest in low lying hills through which perennial and intermittent streams flow. These features consist of reworked older alluvium. The alluvial fans are the sites of active stream deposition of sand and silts derived from the Sierra Nevada and the dissected uplands. The overflow lands and lake bottoms lie in the central part of the Valley where silt and clay accumulate in quiet lake and marsh environments. The subject property is located on a flat grade with average approximate elevation of 407-feet above MSL. The property is underlain by alluvial fan deposits created from sediments transported and deposited by tributaries of the Kern River. The underlying sediments consist of gravels, sands, silts, and clays. The Central Valley of California is underlain by a broad and deep hydrogeologic unit consisting of soil and rock of varying porosity and permeability. Physical dimensions are approximately 50 miles wide at the widest point in the Valley, 400 miles long, and as much as 2,000 feet deep. Recharge to regional aquifers consists of infiltration of seasonal precipitation and percolation of surface waters. The Valley aquifer of greatest storage, highest quality, and greatest accessibility for domestic and agricultural use consists of the alluvial and lacustrine continental deposits extending to depths of 1,500 to 2,000 feet beneath the San Joaquin Valley floor. Lithology and hydraulic properties of these sediments are largely the product of the sediment source and the depositional environment. These sediments range in size from clays to boulders and include all mixtures between the extremes. Those of the west side of the Valley are derived largely from the Coastal Ranges, which tend to consist of shales and fine sandstones with limited permeability.

TRUXTUN AVENUE BAKERSFIELD, CA 93305 661/395-1646 FAX 661/395-1616 3 The east side sediments are derived mainly from granitic materials of the Sierra Nevada which are generally coarser and much more permeable. The majority of groundwater pumped from beneath the area occurs within unconsolidated continental deposits. Depth to unconfined groundwater is estimated at greater than 150-feet below grade. 3.3 Soil Profile Native soil within the excavation consisted of fine-grained buff to tan-brown sand from grade level to approximately 10’ bgs. Also, AEC removed chunks of concrete debris as well as red brick debris in the excavation. It is surmised that the debris was generated following the 1952 earthquake that struck downtown Bakersfield and buried in the open lot. 4.0 TANK REMOVAL PROCEDURES AEC conducted the excavation and removal of the UST on August 9, 2021. The 500-gallon gasoline UST was oriented east-west along the south boundary of the property in the southeast portion of the site. AEC mobilized to the site with Crider Construction which provided the backhoe and operator. Initially, the asphalt surface was removed and the top and sides of the UST were uncovered. The interior of the 500-gallon gasoline UST had approximately 130-gallons of water in the tank with a sheen of weathered gasoline on the water surface. Following uncovering of the tank a window was cut into the tank top and the water was removed. The interior of the tank was then cleaned using a pressure washer to remove any residual solids and scale. The rinseate was pumped from the tank interior and transferred to three 55-gallon drums for transport offsite. During the excavation process no visually stained soil, hydrocarbon odor, or elevated photoionization detector (PID) readings were detected. Also, following cleaning of the tank there was no LEL readings within the tank interior and the oxygen reading was 20.9. Prior to removal of the tank the interior was inerted using 20-pounds of dry ice. AEC monitored the oxygen concentration and lower explosive limit (LEL) within the tank interior using a RKI Eagle LEL/Oxygen meter; upon approval from the BFD the UST was deemed acceptable for safe removal. The UST was removed from the excavation using the backhoe and loaded into the bed of the dump truck for disposal at SA Recycling in Bakersfield, California. Following removal of the UST, AEC collected soil samples from approximately 10’ below ground surface (bgs) beneath each end of the tank. The tank excavation was subsequently backfilled and compacted. 4.1 Soil Sample Location and Collection Procedures Two discrete soil samples were collected beneath each end of the UST (3’ beneath tank invert or 10’ bgs). No visual indication of hydrocarbon contamination was observed during the UST removal procedures and subsequent soil sample collection procedures. All sample collection locations and procedures were conducted in accordance with UST removal permit requirements of the BFD. The following protocol was observed during sampling procedures: • The backhoe was used to obtain a representative sample of native soil from beneath each end of the UST at 10’ beneath tank invert; • An AEC geologist pushed a clean stainless steel sleeve into an undisturbed portion of the soil within the backhoe bucket leaving no head space within the container; • The sampling containers were sealed with Teflon-lined plastic end caps, labeled, and stored in a cooler chilled to approximately 4-degrees Centigrade; Tank Closure Report Advanced Environmental Concepts, Inc. 823 19th Street • ENVIRONMENTAL CONCEPTS WITH DESIGN IN MIND • 220 E. TRUXTUN AVENUE BAKERSFIELD, CA 93305 661/395-1646 FAX 661/395-1616 4 • The soil samples were recorded on a Chain-of-Custody document to ensure sample integrity and traceability; • Analytical tests were performed by BC Laboratories, Inc., a California-certified Laboratory located in Bakersfield, California. 5.0 LABORATORY ANALYSIS and RESULTS The analyses specified and performed on the soil samples were in accordance with accepted State of California Department of Health Services (DHS) laboratory procedures for Total Petroleum Hydrocarbons as carbon chain (TPH-cc) by EPA Method 8015, Volatile Organic Compounds (VOCs) and fuel oxygenates by EPA Method 8260B, and Total Lead by EPA Method 6010B. The analytical results are summarized in the following table and the laboratory reports and chain of custody documents are presented in Appendix E of this report. Units of measurement presented in Table 1 are reported in milligrams per kilogram (mg/kg), equivalent to parts per million (ppm) for Total Petroleum Hydrocarbons as carbon chain (TPH-cc), lead, and Volatile Organic Compounds.

Trace detections of lead were identified in both soil samples; however, the concentrations are well below the regulatory comparative standard for a commercial-use property. The former tank emplacement has been backfilled with the stockpiled native soil removed during the uncovering of the UST followed by clean import fill. The backfill material was placed in approximate two-foot lifts and tire-rolled for compaction. 7.0 RECOMMENDATIONS Based on the trace to non-detectable concentrations of TPH, VOCs, and lead identified beneath the former UST that do not exceed either the commercial-use and/or residential-use Bay Area RWQCB Environmental Screening Levels (ESLs) AEC recommends that no further investigation is warranted for this site.
