Street,Bakersfield (Site),see Figure 1 for an Area Map. ' The following Work P lan outlines RAM Environmental's P ro osed'methodolo gY for conducting a preliminary site assessment at the Fastrip Market, located at 6401 South H. ' Street. Further assessment of the Site is required by the Bakersfield Fire Department Office of Environmental Services(BFDES).in its letter dated November 29, 2004 (see Appendix A for a copy BFDES correspondence).; RAM proposes to advance 8 borings 4o an approximate maximum depth of 30- feet below. ground surface(bgs)with a Geoprobe® and analyze 44 soil samples for TPH as gasoline, ' BTEX, and MTBE during this phase of site assessment. This work is being required by the Bakersfield Fire Department Environmental Services Division (BFDESD) in its letter ' dated November 29,'2004, as a result of the discovery of hydrocarbon containing soil beneath the area former Tank 4 (an unleaded or medium grade gasoline UST)'and the former Tank 1 (a diesel UST). This Site Investigation Workplan;follows the guidelines presented in, Apperdix A Reports Tri-Regional Board Staff RecommendationSTor Preliminary Investigation and Evaluation of Underground Tank Site(April, 2004). ' 1.1 Responsible Party/ Contact Information The responsible party for the Site is JACO OIL;.the company contact person is Mr. Roy Saunders, 3101 State Rd.,Bakersfield, California; telephone (661) 428-5761.The ' consultant contact is RAM Environmental, Richard Casagrande or.Jane McNaboe; .210320th Street, Bakersfield, California, 93301, telephone (661) 324-6152. 1 ' '' 2000_203_Site Investigation Workplan 2 South H and Panama Lane Project#200203 December 2004 ' 2.0 PURPOSE AND SCOPE The purpose of this workplaii is to outline the methodology for conducting a Preliminary Site Assessment of the Panama and South H Fastrip (Site), the workplan-tasks are the '.. . following: ' • Develop"a Workplan and a Health and Safety plan for the Site assessment, • sample 7 borings with a Geoprobe®to evaluate the vertical and lateral extent of hydrocarbon containing soils at the Site, ' • analyze soil samples collected at 5-foot intervals, beginning at 10-feet bgs for TPH-g, TPH-d, and BTEX with the presence of MTBE confirmed and quantified as necessary, • collect water samples (if encountered) and analyze for TPH-g, TPH-d, and BTEX with the presence of MTBE confirmed and quantified, • report Site Investigation Results to BFDES: 3.0 SITE DESCRIPTION ' 3.1:Site Description The Site is'a JACO owned and operated Fastrip gasoline station and convenience store. ' Overhead electrical utilities parallel South. H Street above the.sidewalk adjacent to the Site. Underground utilities also-parallel South H Street adjacent to the service station. There is a storm drain located at the northwest corner of the intersection of South H Street and Panama Lane. 3.2 Location' and Current Use t The current use of the Site is as a•JACO OIL-owned Fastrip•self--serve gas station and convenience store. Immediately adjacent to the Site.are commercial and residential developments. South H Street borders the Site to the east; and Panama Lane borders the ' site to the south, (see Figure 1 - Area Map). A plot plan of the Site is presented in Figure 2. 4.0 TOPOGRAPHY, GEOLOGY AND HYDROGEOLOGY 4.1 Topography ' The Site is at an elevation of approximately 363-feet above sea level; the topography slopes gently to the south. ' 2000_203_Site Investigation Workplan 3 1 South H and Panama Lane Project#200203 December 2004 4.2 Geology The Site is"located in the San Joaquin Valley, which is.the southern portion of the-Great ' Valley geomorphic.province. The Great Valley is a large alluvial plain approximately 50-miles wide and 400-miles long; it is a trough in which sediments have been deposited almost continuously since the Jurassic (about 160 million years ago). Granitic and metamorphic rocks crop out along most of the eastern and southeastern flanks of the ' Great Valley, while marine rocks of pre-Tertiary age crop out along most of the western flank. The post-Eocene-aged'continental'rocks and deposits in the valley trough,contain ' most of the fresh ground water, and,are underlain by or.contain saline-water at depth in most places. They range in thickness from zero along the flanks of the Great Valley to more than 15,000 feet in the-extreme.southern part, where the base'of the fresh water lies ' at a maximum depth of about 4,700 feet. 4.3 Hydrogeology ' The regional uncorifined'groundwater at'the Site is at approximately 185 feet below. ground service(bgs); the groundwater flows to the southwest.(KCWA 2004). ' The Kern Island Canal,an unlined canal, runs parallel to South H Street, on the,east side of the street. The JACO Fastrip�Site is on the west side of South H Street. ' The Geotracker web site shows an-active LUFT site.one-mile to the north of'the Site; a 7- Eleven,gas station located at 1701 Pacheco Road (Regional Board—Case#: 5T1500351). Groundwater measured in the monitoring wells at the Pacheco.Road site is between: ' 40.94=feet and 57.284eet bgs. It'is likely that the groundwater found at the Pacheco Road site is present due to water leaking from the unlined Kern Island Canal. The JACO Fastrip at Panama and South H Street is located in the same'position'relative to the Kern Island Canal as the Pacheco Road'site; it is reasonable to believe that groundwater may also be encountered between 40 and 60-feet-bgs beneath the JACO ' Fastrip Site. The surface of the groundwater, if encountered, would likely slope away from the canal, to the'west.'. ' KCWA maps show two water wells within one half mile of the Site,both located approximately one half mile north of the Site;near Fairview Road. 1 t ' 2000_203_Site Investigation Workplan 4 South H and Panama Lane Project#200203 December 2004 1 5.0 PREVIOUS WORK Soil sam lin at the Site was conducted on May 25, 2004, as the four former 12,000 p g Y • gallon UST's, piping and dispensers were replaced under BFDES permit#BR-0325. ' The laboratory results from the soil samples taken during the tank removal-are included in section 5.1; the sample locations are shown on Figure 2. A PID meter was used during sampling to monitor volatiles in the soil. Three significant readings were noted in the field. At sample site 8-6 a reading of 22.0 was recorded. At sample site 8-10 a reading of 23:0 was recorded and at sample site 8-12 a reading of 21.0 ' was recorded. Laboratory analyses of soils collected and analyzed during the tank.pull are given in ' Table 5.3, below: 5.1 Summary of Tank Removal Findings ' Dispensers 1 through 4, and Tanks 1 through 3 Results of soil sample analysis (Table 5:1) for samples collected from beneath ' Dispensers 1 through 4 and Tanks 1 through 3 indicate concentrations of TPH-R in soils of"non-detect" (less than the PQL of 0.005 milligrams per kilogram (mg/kg)) to a maximum of 8.4 mg/kg. TPH-d in these samples was predominantly at non-detectable concentrations (less than the PQL of 10 mg/kg), with detections of low concentrations in three samples ranging from 11 mg/kg to 400 mg/kg. Benzene, Tuolene, Ethybenzerie and Xylene BTEX) concentrations in the samples from below dispensers 1 through 4 and Tanks 1 through 3 were ' predominantly"non detect" at the PQLs shown in Table 5=1 (generally less than 0.01 mg/kg). ' The data indicate that concentrations of TPH-g, TPH-d, and BTEX remaining in soils beneath the former Tanks 1 through 3 and Dispensers 1 through 4 are generally one to two orders of magnitude less than the applicable, allowable ' concentrations published in the LUFT Manual (SWRCB, 1989). Historically the LUFT Manual has been used to estimate concentrations that can be left in place ' without posing a threat to groundwater based on site-specific conditions, such as depth to groundwater beneath the sample and average annual rainfall. ' MTBE concentrations from the samples below Tanks 1 through 3 were predominantly less than 5 mg/kg with a maximum concentration of 31 mg/kg in the sample 2 feet below the center of Tank 3, decreasing to 0.092 mg/kg at 12 feet ' 2000_203_Site Investigation Workplan 5 South H and Panama Lane Project#200203 December 2004 below the tank(sample location 8), indicating rapid attenuation to very low concentrations of MTBE. Beneath Dispensers 1 through 4, MTBE concentrations ' ranged from "non-detect" at a PQL.of 0.02 mg/kg, to 0.62 mg/kg. Tank 4 ' The highest concentrations of petroleum hydrocarbons were detected in soil -samples from beneath the center of Tank 4 (sample location 11). At this center location, TPH-d ranged from 6,800 mg/kg at 6-feet below tank bottom (btb) to ' .620 mg/kg 10 feet btb. Both results are less than the LUFT Manual recommended concentration of 10,000 mg/kg for TPH-d remaining.in soil(with groundwater greater than 100-feet below ground surface) and show a 10-fold decrease in concentration within a few feet. TPH-g concentrations increased with depth at sample location 11 (Tank 4), ' concentrations increased from 350 mg/kg at 6-feet btb to 660 mg/kg at 10-feet btb, but again these concentrations were below the LUFT Manual recommended concentration of 1,000 mg/kg for TPH-g, for groundwater 100-feet below ground surface. BTEX concentrations detected at sample location 11 were also below the LUFT ' Manual values with the exception of the'l0-foot sample (sample l 1-10), which, with a concentration of Xylene of 51 mg/kg, was just above the recommended value for Xylene of 50 mg/kg. ' The concentration f MTBE in sample location - e o o M p anon 11 increased from 49 mg/kg at 6. feet btb to 71 mg/kg at 10-feet btb, there is no recommended concentration of ' MTBE that can be left in soil. Samples collected from beneath the south and north ends of Tank 4 (stations 10 ' and 12) showed concentrations of TPH-g, TPH=d, and BTEX ranging from not detected at PQLs to generally one to two orders of magnitude below the LUFT ' Manual values (Table 5-1). MTBE concentrations ranged from "non-detect" at a PQL of 0.02 mg/kg to a maximum of 8.2 mg/kg.-at 10-feet btb on the south end of Tank 4 (sample number 12-10). ' 5.2 Quantity of Contaminant Released ' The location of the contaminated soils together.with.the laboratory analysis indicate both gasoline and diesel leaks. ' JACO Oil has not noted discrepancies in the inventory records for the former tanks. The UST's at the Site passed all `tight' testing prior to their removal. The quantity of hydrocarbons released is unknown.

The highest concentrations of chemicals of concern found in the soil are located at ' sampling location 11. RAM proposes to.asses the-vertical extent of soil'contamination by advancing'a soil boring*(boring B-1) with a Geoprobe®5400 sampling unit. Boring B-1 will be located,as close to sample,location 11.as possible,(see,Figure 3 =Proposed Boring Locations). The boring will be deepened to 10',feet below the lowest,field detectable contamination, or to the depth of the groundwater, if encountered.' The;presence of contamination will be determined by visual inspection of staining or discoloration and by ' using a PID. RAM will assess the lateral and vertical extent of soil contamination by advancing a total ' of six borings. Three borings B-1, B-2 and B-3 will be located in the area of Tank 4, boring B-5 will be located closer to Panama Lane to asses the lateral limit of the plume, and to ensure the plume has not spread toward any conduits formed by underground ' utilities located adjacent to Panama Lane: Boring B-6 will be located to the west of the former Tank 4, beneath the canopy; to assess the lateral limit of the plume to the west. Borings B-8 and B-7 will assess the lateral limits of the plume to the north and east. ' All borin will be advanced with a gs anced Geoprobe® 5.400 sampling unit Soil cuttings will be field screened with a PID, and described by a State of'California Registered Geologist. ' A lithologic log of each soil boring will be created; soils will be described and classified according to the USCS, observations of soil staining or discoloration will be included on the lithologic log. Undisturbed soil samples will be collected at 5-foot.intervals,beginning at 10-feet bgs in the area beneath the former tanks, and beginning at 5-feet bgs in the borings outside the former tank area, for a total of approximately 44 soil samples.i.Samples will be handled according to RAM's.Soil Sampling Plan, which is included iri?Appendix B. The samples will be labeled, stored in an ice cooler cooled with blue ice and then transported to ProVera-Laboratory, Bakersfield, at the end of the working day. The soils will be analyzed for Total Petroleum Hydrocarbons as Gasoline, Total Petroleum Hydrocarbons. ' as Diesel, and BTEX and fuel oxygenates,:as follows: Total petroleum hydrocarbons as gasoline(TPH-g; carbon ran_ge C ' 4=.0 12) using EPA Method 8015M; • Total petroleum hydrocarbons as diesel.(TPH-d, carbon range C 12_ C 24)Using EPA Method 8015M; • BTEX and fuel oxygenates by EPA Method 8260B 2000_203_Site Investigation Workplan 8 ' South H and Panama Lane Project#200203 December 2004 1 When the total depth of each soil boring is reached, as determined in the field from observations, bentonite pellets will be placed in the boring and hydrated. The drill ' cuttings (soil) generated by sampling will be returned to the boring. The boring will by compacted and covered with,an asphalt or cement patch to match the existing grade. If groundwater is encountered a groundwater sample will be collected and analyzed. The Geoprobe boring will be abandoned with bentonite pellets, and backfilled with drill cuttings. If the laboratory analytical results from the groundwater show the presence of 1 hydrocarbons; a Groundwater Site Investigation Workplan will be prepared to characterize any groundwater contamination beneath the Site. ' 6.1 Work Schedule The Site Investigation will began within 45 days after the workplan has been accepted by BFDES. BFDES will be notified approximately 48 hours before fieldwork commences. ' A Preliminary Investigation and Evaluation Report will be submitted to BFDES approximately 45 days after completion of the Site Investigation.

Documentation will include a brief description of topics addressed.and the signatures of all training attendees. I 1 • 2000-05-203—Health&Safety Plan 9 5:0 HAZARD ASSESSMENT 5.1 PHYSICAL HAZARDS Working on a site with gasoline contaminated soils presents a variety of physical hazards ' that are continually present unlike chemical exposures (only a hazard when contaminated materials are present). Some of the hazards are identified below. Physical hazards could include the following: • Falling objects such as tools or equipment, •, tripping over hoses, pipes, tools, equipment or uneven terrain; • tipping or overturning of heavy machinery, 1 • • exposure to noise generated by heavy machinery, • insufficient or faulty protective equipment; and ' • insufficient or faulty operations,erations, a ui merit or tools qp � , • vehicular traffic at and around the site. ' Safety precautions for site hazards are addressed in Section 7.2. 5.2 CHEMICAL HAZARDS It is not anticipated that there will be any chemical ex pos ur es, however, this section is , included as a precautionary measure. It is most likely that the hazard at these sites will bey ' from refined products found during the sampling of the soil. Specific precautions will be taken as the situations at each of the sites dictate. The materials of concern in these 1 ' 2000-05-203—Health&Safety Plan 10 projects are all petroleum hydrocarbons. Following is a discussion of the chemical hazards of petroleum hydrocarbons. Petroleum hydrocarbons may include a wide range of substances, some of very low toxicity and some very toxic. The aromatic volatile petroleum hydrocarbons [benzene, toluene, ethylbenzene, and xylene (BTEX)] are generally of greater concern, in part ' because they are more likely to exist in the worker's breathing zone. In moderate exposures, BTXE compounds all produce similar acute effects including headache, ' narcosis, and anesthesia. Table I (from the Hazard Evaluation Plan (HEP)for Leaking Underground Fuel Tanks (LUFT) Removal Sites developed by the State Water Resources ' Control Board) summarizes the exposure criteria and.health effects of BTXE. Among the aromatic volatile petroleum hydrocarbons, benzene is the primary substance of concern because of its association with leukemia and aplastic anemia in chronic exposure situations. ' The permissible exposure limits (PEL) set by OSHA and the American Conference of Industrial of Governmental Hygienists' (ACGIH) threshold limit values (TLV) for ' airborne exposure are provided in Table 1 for BTEX. Even high concentrations (ppm to percent level) of volatile organic compounds are not reasonably expected to present airborne concentrations at or approaching OSHA PELs or ACGIH TLVs considering the small volume of soils to be generated and processed during drilling and sampling operations an d that all field work will be conducted outdoors in well-ventilated areas. ' Considering relative volatility of each compound and the open working conditions, these compounds are not reasonably expected to present inhalation exposures of concern'to ' worker health and safety in open atmospheres. However, air monitoring for organic vapor concentrations will be conducted for activities that present potential inhalation texposures as described in Section 6.0. ' Petroleum hydrocarbons can also be absorbed through the skin if contact with highly contaminated materials is made (i.e. saturated soils). Dermal exposures will be controlled through the use of personal protective equipment (PPE) as described in Section 8.0 and through minimization of exposure to airborne dust generated sampling activities. ' 2000_05_203_Health&Safety Plan 11 ' EXPLOSION AND FIRE The types of hydrocarbons expected to be present,(gasoline fuel) are,not expected to generate vapors'at explosive concentrations during any of the tasks to be performed. If ' vapor monitoring detects concentrations at 'a level that: exceed'the requirements for respiratory protection (>50 ppm), operations, will be suspended and the area will.be evacuated until an industrial hygiene sampling is completed to characterize the exposures. The potential for explosion and fire will be reevaluated based upon-,this characterization. 1 , 1 ' 2000_05_203_Health&Safety Plan 12 Table 1.

During drilling, readings will be taken initially in the worker-breathing zone, the immediate operations area, and recorded in the project ,field notebook.., The OSHA PELs and ACGIH TLVs for aromatic volatile, organic, compounds are listed in Table 1. ' Benzene with an 8-hour time-weighted average (TWA) exposure limit of 1 ppm and a 15- minute short-term exposure limit (STEL) of 5 ppm is the primary airborne contaminant of concern. Table 2 provides an estimation of. airborne benzene concentrations and allowable exposure time based' on Hnu readings. Using these estimates of benzene concentration based on OVA readings. would be protective of worker,health and safety, because the OVA detects a.wide variety of,organic vapors whereas the Hnu detects only aromatic volatile compounds and other large organic molecules. For simplicity, the more ' restrictive estimates based on Hnu readings are used to establish air monitoring.action levels described below. A sustained Hnu or OVA reading of 5 ppm (5 units on the Hnu) above background will trigger donning, respiratory protection (half or full face APR with organic vapor cartridges) and additional ambient air monitoring (breathing zone will be monitored every 15 minutes). If sustained ambient'air organic vapor concentrations equal or exceed 50 ' ppm, work will be stopped and the area evacuated. Because identified materials of concern are not expected to contain significant levels of volatile organic compounds, sustained readings of 50 ppm or higher indicate the need-for industrial hygiene sampling to characterize the exposure. Based upon the results of this sampling, protection measures will be reevaluated.- Air monitoring action levels and associated protective measures are summarized in Table 2.

' SYMPTOMS OF CHEMICAL EXPOSURE ' Field operations personnel shall inform each other of non-visual symptoms that may indicate chemical exposure such as: 1 . 2000-05-203—Health&Safety Plan 16 • Headaches • dizziness, ' nausea, . ' blurred vision, • cramps • irritation of eyes, skin, or respiratory tract, • changes in complexion or skin.discoloration, • changes.in apparent motor coordination, • changes in personality or demeanor, ' excessive salivation or chan es•in papillary response; and • changes in speech ability or pattern. HEAT STRESS The following recommendations will help to-reduce heat stress: • Provide plenty of liquids, wearing f an undergarment that acts to help ventilation of the body, g g p Y, ' scheduling of activities during the cooler times of the day, ,. providing sunshade over the work area if possible, 2000-05-203—Health&Safety Plan 17 • establish a work schedule incorporating oratin regular rest periods, rP g • mandate work slow-downs as needed, • heat stress monitoring. ' Any of the following techniques can be used to screen for heat stress: • Heart rate at the radial.artery-should-be measured as early as possible in the resting period. Should the heart rate exceed 110 beats per minute, the next-.work period.should be shortened by 10 minutes (33%),, while the length of the rest period stays the same. If the.pulse rate is greater than 100 at the next rest period, the.following work cycle should be.shortened ' by 33%. ' Body temperature can be used to screen for heat stress. If the oral temperature at the beginning of the test period exceeds 99 degrees Fahrenheit, the next work period should be shortened by 10 minutes (or 33%), while the length of the rest period stays the same. This process should be continued until the body temperature does not exceed 990F. • Body water loss can be monitored,using a scale to measure change's in, tbody weight. i 7.2 TRENCHING SAFETY PRECAUTIONS The following safety precautions shall be followed by all field project personnel during drilling operations. 1 • Underground utilities will be located and,'marked prior.to commencement ' of drilling activities, ' during the drilling operation, two persons (one designated as "operator" and the other as "site safety") must be present at all times, 2000_05_203_Health&.Safety Plan 18 • the, drilling rig or other mechanical equipment.must always maintain an overhead clearance of a minimum of 10 feet from any overhead'electric lines, '. •• hardhat, safety glasses,'and steel-toed,hoots will be worn in'the operations area, • hearing .protection .'shall be worn when noise levels from operating ' equipment interfere with normal conversation at 5 feet (noise levels are likely above 85 decibels),, • all rotating or ener g ized parts in which worker could become entangled or injured shall be covered or guarded to the extent possible; • wearing loose clothing around operating machinery is prohibited, • exposure to generated dusts during any activity should be avoided and/or ' minimized.

(RAM),.on ' June 22, 2006, in the area of former underground storage tanks (UST's) located at the Jaco Fastrip service station, 6401 South.H Street, Bakersfield, California. The site evaluation was requested by the Bakersfield Fire Department Office of Environmental ' Services (BFD) after a preliminary site assessment resulted in the discovery of gasoline and diesel impacted soils beneath the f6rmer UST's when the tanks were removed for replacement. Soil samples were collected from five,borings s develo ed with a GeoProbe in the former, p g P. UST area, to a maximum depth of 35 feet below ground. No groundwater was ' encountered while drilling. During the fieldwork there were no visible signs of stained soils and the Photo Ionization.Detector did not detect any volatile organic c6mpounds. Permission was obtained from Mr. Ralph Huey of the BFD to decrease the number of ' borings scheduled in the Workplan. The deepest two soil samples from each boring were analyzed by a California Certified ' laboratory for chemicals of concern; all results were non-detect(below the laboratory detection limit). RAM recommends that a"No Further Action" letter be issued by the BFD for this site. 1 1 1 1 ' 2000_03_203_PIER,Panama&S H 2 ' 6401 South H Street,Bakersfield Project#200203 ' July 2006 PRELEVIINARY INVESTIGATION AND EVALUATION REPORT JACO OIL COMPANY'S FASTRIP SERVICE STATION 6401 SOUTH H STREET,BAKERSFIELD,CALIFORNIA 1.0 INTRODUCTION 1 ' RAM Environmental Engineering, Inc. (RAM) is pleased to present this Investigation and Evaluation Report(Report) for the JACO OIL owned Fastrip self serve gas station ' and convenience store (Fastrip#362), located at 6401 South H. Street, Bakersfield (Site), see Figure 1 for an Area Map and Figure 2 for a Plot Plan of the Site. tA letter from the Bakersfield Fire Department Office of Environmental Services (BFD) dated November 29, 2004 requested a Workplan for further definition of;a plume below ' the former western Underground Storage Tank(UST) located at the property (see A Appendix A for copies of regulatory correspondence)... Workplan was submitted to Bakersfield Fire Department in December 2004; a letter dated April 18, 2006 from the ' BFD approved the Workplan (Appendix A). This Report follows the guidelines presented in, Appendix A—Reports Tri-Re ional ' Board Staff Recommendations For Preliminary Investigation and Evaluation of Underground Tank Site (April, 2004). ' 1.1 Responsible Party/Contact Information The responsible party,for the Site is JACO OIL; the company contact person is Mr. Roy Saunders, 3101 State Rd., Bakersfield, California; telephone (661) 428- ' 5761, FAX (661) 393-8738. The consultant contact is RAM Environmental, Richard Casagrande or Jane Mc'Naboe, 2103 20'h Street, Bakersfield, California, 93301, telephone (661) 324-6152, FAX (661.) 324-6172. ' 1.2 Site History Preliminary soil sampling at the Site was conducted on May 25, 2004, as the four ' former 12,000 gallon UST's, piping and dispensers were replaced under BFD permit#BR-0325. A Table summarizing the laboratory analytical results from ' the soil samples taken during the tank removal is included in Appendix B. The preliminary soil sample locations are shown on Figure 3. A PID meter was used during preliminary sampling to monitor volatile organic ' compounds (VOC's) in the soil. Three significant readings were noted in the field. At sample site 8-6 a reading of 22.0 was recorded. At sample site 8-10 a t reading of 23.0 was recorded and at sample site 8-12 a reading of 21.0 was recorded. I The highest concentrations of petroleum hydrocarbons were detected in soil ' samples from beneath the center of Tank 4 (sample location 11). At this center location, TPH-d ranged from 6,800 mg/kg at 6-feet below tank bottom (btb) to ' 620 mg/kg 10'feet btb. Both results are less than the LUFT Manual recommended ' 2000_03_203_PIER,Panama&S H 3 6401'South H Street,Bakersfield Project#200203 ' July 2006 concentration of 10,000 mg/kg for TPH-d remaining in soil (with groundwater greater than 100-feet below ground surface) and show,a 10-fold decrease in ' concentration within a.few feet. TPH-g concentrations increased with depth at sample location 11 (Tank 4), concentrations increased from 350 mg/kg at 6-feet btb to 660 mg/kg at 10-feet btb, but again these concentrations were below the LUFT Manual recommended concentration of 1,000 mg/kg for TPH-g, for groundwater 100-feet below ground ' surface. BTEX concentrations detected at sample location 11 were also below the LUFT Manual values with the exception of the 10-foot sample(sample 11-10), which; with a concentration of Xylene of 51 mg/kg, was just above the recommended value for Xylene of 50 mg/kg. ' The concentration of MTBE in sample location 11 increased from 49 m at 6- p tag feet btb to 71 mg/kg at 10-feet btb, there is no recommended concentration of ' MTBE that can.be left in soil. Samples collected from beneath the south and north ends of Tank 4 (soil sample ' locations 10 and 12)showed concentrations of TPH-g, TPH-d, and BTEX ranging from not detected at PQLs to generally one to two orders of magnitude below the LUFT Manual values (Appendix B). MTBE concentrations ranged from "non- ' detect" at a PQL of 0.02 mg/kg to a maximum of 8.2 mg/kg at 10-feet btb on the south end of Tank 4(sample number 12 710). ' JACO Oil left conductor casings in place at the Site to aid in further evaluation of the soils beneath the former UST's. ' 1.3 Quantity of Contaminant Released The location of the contaminated soils.together with the laboratory analysis ' indicates both gasoline and diesel leaks. JACO Oil had not noted discrepancies in the inventory records for the former ' tanks. The UST's at the Site passed all `tight' testing prior to their removal. The quantity of hydrocarbons released is unknown. ' 2.0 SITE DESCRIPTION 2.1 Site Description The Site is a JACO owned and operated Fastrip gasoline station and convenience store. Overhead electrical utilities parallel South H'Street above the sidewalk ' adjacent to the Site. Underground utilities also parallel South H Street adjacent to the service station. There is a storm drain located at the northwest corner of the intersection of South H Street and Panama Lane. . 1 ' 2000_03_203_PIER,Panama&S H 4 ' 6401 South H Street,Bakersfield Project#20b203 ' July 2006 3.0 TOPOGRAPHY,GEOLOGY AND HYDROGEOLOGY ' 3.1 Topography The Site is at an.,elevation of approximately 363-feet above sea level; the topography slopes gently to-the south. ' 3.2 Geology The Site is located in the San Joaquin Valley, which is the southern portion of the ' Great Valley geomorphic province. The Great Valley is a large alluvial plain approximately 50 7miles wide and 400-miles long; it is a trough in which sediments have been deposited almost continuously since the Jurassic (about 160 . ' million years ago): Granitic and metamorphic rocks crop out along most of the eastern and southeastern flanks of the Great Valley, while marine rocks of pre- Tertiary age crop out along most of the western flank. The post-Eocene-aged ' continental'rocks and deposits in the valley trough contain most of the fresh ground water, and-are underlain by or contain saline water at'depth in most places. They range in thickness from zero along the flanks of the Great Valley to more ' than 15,000 feet in the extreme southern part, where the base of the fresh water lies at a maximum depth of about 4,700 feet. The Site is underlain by an. ' alternating sequence of well-graded sands and clayey silts. 3.3 Hydrogeology ' Groundwater within the southern San Joaquin Valley is derived from rivers 'flowing from the Sierra Nevada Mountains to the east. The closest river to the Site is the Kern River which is located approximately'6 miles to the north. The.., ' regional unconfined groundwater at the Site is at approximately 185 feet below ground service (bgs); the groundwater flows to the southwest(KCWA 2004). ' The Kern Island Canal, an unlined canal, runs parallel to South H Street, on the east side of the street. The JACO Fastrip Site is on the west side of South H Street. The Geotracker web site shows an active LUFT site one-mile to the north ' of the Site; a 7-Eleven gas station located at 1701 Pacheco Road (Regional Board —Case#: 5T1500351). Groundwater measured in the monitoring wells at the Pacheco Road site is between 40.94-feet and 57.28-feet bgs. It is-likely that the ' groundwater found at the Pacheco Road site is present due to water leaking from the unlined Kern.Island Canal. ' The JACO Fastrip at Panama and South H Street is located in the same position relative to the Kern Island Canal as the Pacheco Road site;*it is reasonable to believe that groundwater may also be encountered between 40 and 60-feet bgs beneath the JACO Fastrip Site. The surface of the groundwater, if encountered, would likely slope away from the canal, to the west. ' KCWA maps show two water wells within one half mile of the Site,both located approximately one half mile north of the Site.,,near Fairview Road. 2000_03_203_PIER,Panama&S H 5 ' 6401 South H Street,Bakersfield Project#200203 ' July 2006 4.0 SITE INVESTIGATION ' Prior to any drilling at the Site, the boring locations were marked with white paint and Underground Services Alert was called in preparation for drilling and soil sampling. On June 22,2006 a GeoProbe operated by InterPhase Inc. advanced 5 soil borings at the Site ' (see Figure 4 for boring locations). Four,of the borings were advanced through conductor casing left in place by JACO Oil for soil sampling, one boring (boring B-7) penetrated the asphalt to the north the former UST location. Soil samples were collected ' in acetate tubes using the GeoProbe at 5-foot intervals beginning at 10-feet below ground surface (bgs). The tubes were capped with Teflon tape followed by a plastic-cap,.labeled and stored in an ice chest with Blue-IceTM, until,transported under chain.of custody ' (COC)to ProVera Labs, Bakersfield. A California State Reg_ istered Geologist described the soil samples and constructed a ' lithologic log of each boring see Appendix C—Lithologic Logs. A Photo Ionization Detector(PID) was used to measure the VOC's in each sample interval; measurements ' were recorded on.the lithologic logs. When the total depth of each boring was reached, the boring was backfilled with bentonite grout. During the site investigation, the PID measured 0.0 except for one soil sample which ' measured 4.2 in Boring B-1 at 25 feet bgs. No visible signs of staining were observed, and no odors were noted. No groundwater was encountered. As there were no signs of ' impacted soils,permission was asked from the BFD (Mr. Ralph Huey) to reduce the number of borings in the Workplan. Mr. Huey reviewed the field data and agreed to reduce the Workplan boring and sampling. Proposed boring B-4 was not used as the ' conductor contained monitoring equipment for the service station. Five borings were developed at the site instead of the planned eight borings (Figure 4). ' 4.2 Soil Sample Laboratory Analysis ProVera.Labs.analyzed soil samples from each boring as follows: ' • Total petroleum hydrocarbons as gasoline (TPH-g, carbon range C4- C 12) using EPA Method 8015M; t • Total petroleum hydrocarbons as diesel (TPH-d, carbon range C 12-C 24) using EPA Method 8015M; ' • BTEX and fuel oxygenates by EPA Method 8260B. 5.0 RESULTS ' A Summary of Soil Sample Analytical Resu 1 is is p re sented m Table 5.1 (page 8). All PID readings were zero except for one reading of 4.2 from Boring 1 at 25 feet bgs. As ' field screening did not detect any hydrocarbons, only the lowermost two soil samples collected from each boring were analyzed by the EPA methods described above, all analytical results were "Non-Detect." ' 2000_03_203_PIER,Panama&S H 6 ' 6401 South H Street,Bakersfield Project#200203 July 2006 1 Soils encountered while drilling included sands and clayey silts. Well graded sand ' extends from the surface to approximately 15 feet bgs; from approximately 15 to 20 feet bgs the site is underlain by moist clayey silt; this in turn is underlain by well graded sand followed by a layer of silt beginning at approximately 30 feet bgs. No groundwater was encountered while drilling. 5.1 Summary of Results ' Table 5.1 (following page) summarizes the soils analytical results, complete Laboratory Reports are included in Appendix D. All analytical laboratory results were "Non-Detect." 1 1 1 1 ' 2000_03_203_PIER,Panama&S H 7 TABLE 5.1 LABORATORY RESULTS SOILS ANALYSIS - SITE INVESTIGATION 6401 SOUTH H STREET, BAKERSFIELD Sample Ethyl m,p,&o Number Depth PID Benzene Toluene benzene X lenes MTBE TBA DIPE ETBE TAME TPH- TPH-d Boring Number- Feet bgs reading mg/Kg Depth BI-10 10 ' 0.0 NA NA NA NA NA NA NA NA NA NA NA BI-15 15 0.0 .
