Box 1956 Paradise, California 95967 (877) 563 -4300 (toll free) PEI Project #1 1-2604A Issue Date: September 30, 2011 SECTION I. INTRODUCTION Pinnacle Environmental, Inc. (PEI) was retained by United Central Bank (Client) to perform a Limited Phase II Environmental Site Assessment (Limited Phase II) of a property at 800 34th Street, Bakersfield, California (Site). The Site consists of an approximate 0.72 -acre parcel of land, occupied by a 3,000 square -foot, single -story retail building, four double -sided gasoline dispensers covered by a large free- standing canopy, and a drive - through carwash. The underground storage tank (UST) system consists of three 10,000 - gallon capacity USTs which were reportedly installed in 1988. The Site is located at the northwest corner of the intersection of 34th Street and Q Street within a commercial area. This Limited Phase II was generally performed in order to evaluate recognized environmental conditions (RECs) identified in a Phase I ESA report issued by PEI for the subject property August 8, 2011. PEI recommended the following (pertinent portions directly excerpted): ♦ Given the potential for releases from fueling systems and the length of time since the last significant subsurface investigation (14 years), PEI recommends a subsurface investigation at the subject property. ♦ PEI recommends comprehensive inspection and testing of the UST systems (including leak detection systems) by an accredited UST professional in consultation with the local regulatory agency representative to evaluate the system integrity and compliance with state and local regulations. PEI also recommends verification of proper environmental insurance for the UST systems. The carwash clarifier should be cleaned and inspected by a licensed hazardous waste disposal contractor, and if leaks are suspected, the clarifier should be included in the recommended subsurface investigation of the subject property. The scope of work completed for this Limited Phase II includes a subsurface assessment performed in accordance with the August 12, 2011 proposal that was approved by the Client. The scope of work included the sampling of up to eight (8) soil borings and analysis of up to fourteen (14) soil samples. The completed scope of work included the drilling of one (1) background and eight (8) exterior locations. Seventeen (17) soil matrix samples were submitted to the lab and eleven (11) of these samples were analyzed for volatile organic compounds (VOCs) by EPA Method 8260E and total petroleum hydrocarbons (TPH) differentiated by carbon chain length (ccid) by EPA Method 8015M. Seven samples from depths of 29- to 30 feet below ground surface (bgs) were held pending the results of the shallower samples. Since no VOCs or TPH was detected in any of the shallower samples, the deeper samples were not analyzed. It should be noted that while two borings were advanced near the carwash clarifier, the contents of the clarifier were not cleaned and inspected by a licensed hazardous waste disposal contactor. The cleaning an inspection was not included in the scope of work, but can be performed at a later date if desired. Limited Phase II Environmental Site Assessment Pinnacle Environmental, Inc. 80034 1h Street, Bakersfield, CA 93301 Page 2 C. LIMITATIONS The Limited Phase II findings are based on the conditions existing at the site on September 9, 2011, when the field sampling was performed. This work was performed in accordance with the August 12, 2011 proposal that was approved by the Client and the site owner.' This Assessment has been conducted and prepared in accordance with generally accepted practices and procedures exercised by reputable professionals under similar circumstances. PEI makes no other warranties or guarantees, either expressed or implied, as to the findings, opinions, or recommendations contained in this report. This Limited Phase II was not fully comprehensive in nature but was restricted to areas near clarifiers, dispensers, current underground storage tanks (USTs), a former waste oil UST, and one background location. The findings presented in this report were based on the subsurface conditions encountered in the areas investigated during the time frame of this assessment. These findings may not be considered representative of future conditions in the .areas investigated or conditions in any untested areas of the site. This investigation was performed in accordance with generally accepted practices of the profession undertaking similar studies at the same time and in the same geographical area. No other warranty is expressed or implied. It should be recognized that this study was not intended to be a definitive investigation of potential impact at the subject property. Given that the Scope of Services for this investigation was limited and that the investigation was further limited by the lack of accessibility in some areas, it is possible that currently unrecognized impacts (or higher levels than those found) may exist at the site. Therefore, PEI cannot act as insurers and cannot "certify" that a site is free of environmental contamination, that impact does not exist below a certain level in other areas of the site, or that some other, currently unrecognized, environmental. impact does not exist at the site. The recommendations provided in this report do not constitute legal advice and should not be relied upon in any way for legal interpretations. This report has been prepared for the sole use of the Client. This report may not be relied upon by any other party without the written authorization of PEI and the Client. The Scope of Services performed in the execution of this investigation may not be appropriate to satisfy the needs of other private users or public agencies, and. any re -use of this document or the findings, conclusions, or recommendations presented herein is at the sole risk of said user. This report is not necessarily designed to be used for regulatory review or closure purposes, but simply to facilitate a real estate transaction or review. Limited Phase II Environmental Site Assessment Report Pinnacle Environmental, Inc. 800*34'h Street, Bakersfield, CA 93301 Page 4 B. PHYSIOG.RAPHIC AND TOPOGRAPHIC CONDITIONS The subject property's physical setting was researched employing a United States Geological Survey (USGS) 15 Minute Topographic Quadrangle (Quad) Map relevant to the subject property (Figure 1, Appendix A). The USGS 15 Minute Quad Map has an approximate scale of 1 inch to 16,500 feet, and shows physical features such as wetlands, roadways, mines, and buildings. The USGS 15 Minute Quad Map was used as the Standard Physical Setting Source, and is sufficient as a single reference. The Oildale, California Quad Map (dated 1973) shows no physical features that are likely to environmentally impact the subject property. The subject property is identified as unspecified urban developed land (white shading). No mines, wells, aboveground storage tanks, or wetlands were depicted in the immediate area of the subject property. The elevation of the subject property is approximately 410 to 415 feet above mean sea level with a slight topographic gradient to the southwest. C. LOCAL AND SITE GEOLOGY The general area of the subject property is located within the San Joaquin Valley where the Sierra Nevada, Great Valley, and Coastal Range physiographic provinces meet. The San Joaquin Valley consists of dissected uplands, alluvial fans, overflow areas, and lake bottoms. The alluvial fans are the sites of active stream deposition of sands and silts derived from the Siena Nevada and 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 soils beneath the Site are medium- to fine- grained sands that grade with depth to sand containing less than five percent by volume small, angular gravel comprised largely of quartzite fragments. All soils encountered were arkosic, containing unweathered potassium feldspar and flakes of biotite mica. The upper four feet of sand at several locations was organic, however no rootlets, burrows, fossils, or caliche were noted in any soil samples described. The sands were very well sorted and poorly graded, with only one or two grain sizes noted in every soil sample. Oxidation was not present. No depositional structures, such as cross- bedding, were noted in any of the borings. The inferred depositional environment is fluvial or alluvial. D. LOCAL AND SITE HYDROGEOLOGY Groundwater was not encountered in any of the borings drilled to depths of thirty feet bgs on site. The soil was consistently moist at depths of approximately 16- and 29 feet bgs in every boring. At these two depths, the soil was slightly more silty and organic and may represent paleosols. At no drilling location was there enough moisture to pool or collect and so this moisture is not considered "groundwater ". Geotracker data from a location 0.75 miles southwest of the Site shows groundwater at a depth of 117 to 124 feet bgs. Online data also suggest that groundwater moves in a southeasterly direction, Limited Phase II Environmental Site Assessment Report Pinnacle Environmental, Inc. 80034 1h Street, Bakersfield, CA 93301 Page 6 PEI prepared a Phase I Environmental Site Assessment for the United Central Bank dated August 8, 2011. Observations noted by PEI include the following (summarized): This area has a history of cultivated farmland use prior to 1941. The subject property has been occupied by a gasoline service station since approximately 1970. Automotive repair was performed on the property from 1970 to 1999 when the automotive service bays were remodeled into the current convenience store. No removal or soil sampling data are available for the two former hydraulic lifts and lube pit which reportedly existed in the three former service bays. It is unknown whether an oil /water clarifier may also have been extant. . The original fuel USTs and one waste oil UST were removed from the property and replaced with the current systems in 1988, apparently in the same location as the former USTs. According to the records reviewed, the soil sampling from the fuel USTs' pit did not show environmental impact; however moderate petroleum impact was noted in soil beneath he northern fuel dispenser. The depth of the soil samples and quantity and final disposition of the impacted soil was not obvious in documentation reviewed by PEI, although Chevron indicated that the impacted soil had been removed. Subsequent sampling in 1997 did not discover indications of environmental impact beneath that dispenser. In September 1999, the 1,000 - gallon capacity waste oil UST was removed and no significant impact was discovered. No subsequent environmental investigations have been completed since 1999. The most recent compliance information for the subject property was provided to the Bakersfield Fire Department in January 2009. It included a corrective action notice for various leak testing requirements. PEI recommended a subsurface investigation at the subject property. Limited Phase 11 Environmental Site Assessment Report Pinnacle Environmental, Inc. 800 34'" Street, Bakersfield, CA 93301 Page 8 All down -hole drilling equipment was decontaminated using a three stage process of a non - phosphate grade detergent (Alconox) mixed with potable water, a potable water rinse and a de- ionized water rinse. After collection of the soil samples, each borehole was backfilled to near - surface with hydrated bentonite, then sealed with a plug to match the existing asphalt. D. SOIL MATRIX SAMPLING Discrete soil samples were collected for laboratory analysis at a depth in each boring of 4- to 5 feet, 9- to 10 feet, 19 -to 20 feet, and /or 29- to 30 feet bgs, depending upon the boring location. Field observations (e.g. odor, coloration, dampness, and /or PID readings) were used to determine sampling depths. Disposable gloves (changed between each boring) were utilized to limit cross - contamination between core samples. Soil samples were collected in 1.5 -inch diameter by 12- inch long clear acetate sleeves cut by hacksaw from each coring run (4 feet in length). The acetate sleeves were capped with TeflonTM sheets and caps and placed in a cooler filled with ice. The samples were thus kept at a temperature of approximately 4 °C before being delivered to the laboratory. Soil samples were analyzed for VOCs by USEPA Method 8260B and TPH differentiated by carbon chain length (ccid) by EPA Method 8015M. Limited Phase II Environmental Site Assessment Report Pinnacle Environmental, Inc. 800 34`h Street, Bakersfield, CA 93301 Page 10 SECTION VI. CONCLUSIONS AND RECOMMENDATIONS Pinnacle Environmental, Inc. (PEI) was retained by United Central Bank (Client) to perform a Limited Phase II Environmental Site Assessment consisting of 9 borings for soil matrix sample collection and analysis. The subject property is located at 800 34th Street, Bakersfield, CA. This Limited Phase II was performed in order to assess recognized environmental conditions (RECs) identified in an August 8, 2011 Phase I ESA report issued by PEI for the subject property. The RECs identified relevant to this report included the possible impact to the subsurface by a three -stage clarifier associated with the carwash, the former location of a waste oil UST, the pump islands, and the former (and current) location of product USTs. The scope of work for this Limited Phase II included a subsurface assessment performed in accordance with the August 12, 2011 proposal that was approved by the Client. The scope of work included the sampling of soil at 8 boring locations, and a 9th boring was added as an assumed background location. Seventeen soil matrix samples were submitted to the lab and eleven samples were analyzed for VOCs and TPH (ccid). Six deep soil samples were not analyzed when the shallower samples at each location were shown to be not impacted by the compounds of concern above detection levels. No potential locations of unknown USTs or other items of concern were found during historical document review or by the geophysical survey. Initial laboratory analyses of I1 selected soil samples from 9 boring locations showed no concentrations of VOCs or TPH (ccid) were detected above laboratory detection limits. Therefore, further subsurface assessment is not warranted at this time. However, as discussed in PEI's Phase I ESA, there may be localized residual petroleum hydrocarbon impact located on -site in areas of the historic hydraulic lifts, service bays and the like, associated with the former gasoline service station. These residual impacts (if any) are unlikely to present a significant issue unless the property is - demolished or if significant subsurface work is performed. In addition, the on -site clarifier related to the current car wash should be -inspected and cleaned, although based upon the soil sample results, the clarifier does not appear to present a significant threat-of environmental impairment to the subject property at the present. Finally, the UST system test results, included as part of the scope of work herein, are provided under separate cover.

EVALUATION OF RESULTS This Limited Phase II was performed in order to evaluate recognized environmental conditions (RECs) identified in a Phase I ESA report issued by PEI in August 2011. A geophysical survey of select exterior areas of the subject property evaluated the property for current or past large buried metallic anomalies (e.g., USTs) and found no evidence of unidentified anomalies or USTs. Down hole and soil sample PID readings were measured to be 1.0 ppm or Iess in every instance. Multiple background ambient air readings resulted in measurements that were usually 0.0 ppm but "peaked" at 0.2 ppm. The laboratory results of soil matrix samples collected from 9 soil borings show that there are no VOC or TPH concentrations above laboratory detection limits anywhere soil matrix samples were collected. The data are presented in Table 1 below: TABLE 1 - ANALYTICAL RESULTS g X.7,Q p r.., , r ., ND <10 i li' 1`r` .r y� ka7q�.4 t It :: ., ��{i">tf7qs �; s ♦Li j3 a g gn ,+' *,f �e " "`�:?�•+ ¢' s " ND <10 ND <10 ran < 0.005 to 0.02 ND <10 ND <10 ND <10 ND < 0.005 to 0.02 014 y� ND <10 ND <10 ND < 0.005 to 0.02 ND <10 ND <10 ND <10 ND < 0.005 to 0.02 ND <10 ND <10 ND <10 ND < 0.005 to 0.02 I }; a ND <10 ND <10 ND <10 ND < 0.005 to 0.02 7�� , ND <10 ND <l 0 ND <10 ND < 0.005 to 0.02 B= $raf�Q`r .: s �.,..

FIELD ACTIVITIES A. UST SYSTEM INTEGRITY TESTING PEI retained the services of a Confidence UST Services, Inc. (CUSI), a California licensed UST integrity testing firm to assess the general compliance and integrity of the current UST systems. CUSI's scope of work generally included: secondary containment testing (e.g., tank annular, piping sump, piping, dispenser sump); precision test 3 USTs /lines and dispenser; annual monitor certification; leak detector testing; vapor recovery testing with dispensers. The CUSI report will be submitted under separate cover from this subsurface investigation report. B. HEALTH AND SAFETY PLAN A site - specific Health and Safety Plan (HASP), compliant with the requirements of 29 CFR Part 1910.120, 8 CCR 5192, and the EPA Standard Operating Safety Guides for Hazardous Waste Operations (1986) was developed by PEI prior to field activities. Based on the conditions of the site, the expected levels of constituents present in the soil, and the type of work performed, all activities were conducted in Level D Personal Protective Equipment (PPE). The HASP provided the requisite details and guidance. All PEI employees involved in field work at this site previously completed the required 40 hours initial training, had maintained qualification through annual refresher training, are under a program of medical monitoring, and are certified to wear respiratory protection, as specified in 29 CFR part 1910.134 and 8 CCR 5144. The site safety officer conducted a tailgate safety meeting prior to the start of drilling activities. PEI retains the signed Health and Safety Plan in the project file. Underground Service Alert (USA aka Dig Safe) was contacted on August 24, 2011. The Dig Alert ticket number was #274812. C. DRILLING METHODS PEI obtained the drilling services of Interphase for the September 9, 2011 field work to obtain the soil matrix samples at the Site, with a Geoprobe® 6600. The field work was accomplished in one field day. Weather at the time of the drilling was a warm temperature of about 90 °F. The proposed scope included 8 soil matrix sample locations. However, due to field conditions and available time, one additional assumed "background" boring was completed (see Figure 3, Appendix A). Two borings (B -1 and -2) were located adjacent to a three -stage clarifier associated with the carwash. One boring (B -3) was placed adjacent to the former location of a waste oil UST. One boring (B -4) was placed at an assumed background location. Based upon historical research (Pinnacle, 2011), this boring location is away from previous or current site activities. Two borings (B -5 and B -6) were located adjacent to the pump islands. Soil borings B- 7, -8, and -9 were located on three sides of the UST farm. Limited Phase II Environmental Site Assessment Report Pinnacle Environmental, Inc. 800 34" Street, Bakersfield, CA 93301 Page 9 similar to the gradient at the Site. However, the local groundwater may be influenced by several factors, and may not conform to the reported nearby pattern. E. SUMMARY OF PREVIOUS INVESTIGATIONS Previous environmental documentation concerning the subject property includes a Phase I Environmental Site Assessment prepared by Envirodox for United Central Bank dated August 19, 2009. That report concluded the following (directly excerpted): The following historical recognized environmental conditions (HRECs) were identified in connection with the property: Based on the historical records, an auto repair service with two hydraulic lifts operated on the subject property from 1970 until the hydraulic lifts were removed and auto repair ceased in 1999. The former auto repair area was renovated into the current mini mart area in 1999. Subsurface condition in the former auto repair area cannot be identified due to lack of historical investigation records, however, based on year of building renovation in 1999, possible discoloration or visible contamination (from hydraulic tank leak or surface leak) present at the time of the hydraulic lift removal, soil excavation, and backfll must have been encountered and reported to government official within the permit and field inspection process. No records of violation, on -site contamination, were found during the years of auto repair operation. No further action or subsurface investigation is recommended for the property at this time. The Envirodox report references an October 31, 2001 Phase l ESA that was completed by ADR Environmental Group (ADR) for the owner of the subject property, Ms. Lina Yoo. The Envirodox report provided the following review of the ADR report (directly excerpted): Based on the ADR's review of available historical information, the subject property was historically agricultural land until approximately 1941 when a portion of a military barracks installation was constructed on the subject property and properties to the north and west of subject property. A gas station was constructed in 1970. The carwash was installed and the auto service bays including hydraulic lifts and associated piping were removed in 1999. ADR recommended that all suspect asbestos - containing materials should either be presumed to contain asbestos or adequate rebuttal sampling should be conducted by an HERA accredited building Inspector prior to renovation, including maintenance, or demolition if these activities will disturb the material(s).

GENERAL, SITE DESCRIPTION This section provides a brief description of the site, the physical setting of the site and vicinity, and a summary of previous environmental investigations. A. DESCRIPTION OF SITE AND VICINITY The Site consists of an approximate 0.72 -acre parcel of land, occupied by a 3,000 square -foot, single -story retail building, four double -sided gasoline dispensers covered by a large free- standing canopy, and a drive - through carwash. The underground storage tank (UST) system consists of three 10,000- gallon capacity USTs which were reportedly installed in 1988. The Site is Iocated at the northwest corner of the intersection of 34th Street and Q Street within a commercial area. The Site is located at the northwest corner of the intersection-of 34th Street and Q Street within a commercial area. The subject property location is shown on Figures 1 and 2 in Appendix A. The property is bordered by the following: North: Immediately by a parking lot (for the western adjoining commercial building), then by a commercial -use property occupied by medical offices (3551 Q Street), then by a commercial -use property. East: Immediately by Q Street, then by a commercial -use property occupied by a convalescent home (Life House Retirement Property, 730 34th Street). South: Immediately by 34th Street, then by a gas station (Fastrip Gas, 805 34th Street) and commercial building (Medi -Stop, 815 34th Street), then by residential -use property. West: Immediately by two -story commercial -use property (medical -use tenants, 820 34th Street), then by commercial -use property. The Site is located at the northwest corner of the intersection of 34th - Street and Q Street within a commercial area. The site location map is provided as Figure 1 adapted from on -line versions of the OildaIe, CA Map (dated 1973). An aerial photograph site diagram is provided as Figure 2. A site diagram showing soil boring locations is provided as Figure 3. All these figures are included in Appendix A. Limited Phase II Environmental Site Assessment Report Pinnacle Environmental, Inc. 800 34 "' Street, Bakersfield, CA 93301 Page 5 SECTION II. SCOPE OF WORK & LIMITATIONS A. PURPOSE The purpose of this Limited Phase II is to assess RECs identified in an August 2011 Phase I ESA conducted by PEI on the subject property. The objective of this Limited Phase II Site Assessment is to collect and quantitatively analyze original samples of soil in such a manner as to reduce uncertainties about the physical and chemical characteristics of this media in limited areas. The boring locations were selected to identify areas of potentially unknown impact from the current subject property operations (e.g., USTs, dispensers). B. SCOPE OF WORK Based on information available to PEI, the following scope of work was proposed: I. Preparation of PEI Health and Safety Plan and notification of Dig Alert/Underground Service Alert (USA). 2. PEI will meet with someone knowledgeable about the property, if available, in an effort to identify on -site utilities. In addition, a private on -site utility locating firm (e.g., geophysical survey) will be retained in an attempt to delineate the on -site USTs, and locate metallic utilities for the proposed boring locations. 3. Drilling of up to eight (8) exterior soil borings. Six borings will be completed up to 30- feet below ground surface (bgs) and two (2) borings will be completed up to 10 feet bgs using direct push technology (e.g., Geoprobe). Borings will be located based upon information provided within the Phase I information, visual observations, and geophysical data. Based on field conditions, PEI completed one additional boring for background analysis. 4. Initial laboratory analyses of up to fourteen (14) soil samples (depending on field observations) and based upon those results, potential analysis of additional samples with Client approval. 5. UST Integrity Testing - PEI will retain the services of a UST integrity testing firm to assess the general compliance and integrity of the current UST systems. Proposed work generally includes: tank integrity testing, product line and leak detector testing, vapory recovery testing, SB 989 spill containment testing, and annual monitor certification. 6. Report preparation by PEI. The purpose of this proposed limited subsurface screening investigation is to evaluate whether the subsurface in limited areas at the subject property has been impacted by VOCs and /or TPH. Sub- surface soil sampling was proposed for this limited scope screening investigation. Groundwater and soil vapor sampling were not included in this investigation. Disposal of aforementioned hazardous materials was not included as part of this assessment.
