(AEC) is pleased to present this summary letter for the ' collection of soil samples from the spoils pile at the Express Gas Mini Mart facility, 928 Flower Street, Bakersfield, California. ' On April 20, 2009 an AEC geologist mobilized to the Xpress Gas Mini Mart to collect composite soil samples from the spoils pile generated during repairs to the underground storage tank system. The spoils pile is currently staged at the adjacent to vacant western property and consisted of approximately 200-cubic yards of brown, fine to medium-grained sand. AEC divided ' the spoils pile into four approximate 50-cubic yard quadrants (north, south, east, and west) and collected soil from four discrete locations at varying depths within the interior of the pile. The four discrete samples were combined into one composite each (SP-N-C, SP-S-C, SP-W-C, and SP-E- ' C). The four composite samples were analyzed for TPH-gasoline, BTXE, and MTBE by EPA Method 8015/8021 B by Associated Laboratories, Orange, California (See attached analytical). The soil sample analyses indicated non-detectable concentrations for all constituents tested. ' Therefore, based on the analytical results AEC recommends that no restrictions be placed on the pending soil use as foundation material beneath a concrete slab. Note that the soil samples were collected on a finite grid, therefore, the analytical results.are not meant to be misconstrued as representative of un-sampled areas. If gasoline odor is detected during the loading and transport of the spoils pile, it may be recommended that additional sampling may be required.

(AEC) to prepare this soil assessment report which details the investigation of the potential for vertical migration of gasoline-range hydrocarbons discovered when D the underground storage tank (UST)was uncovered in response to a failing slab proximal to the UST. The service station is at 928 Flower Street, Bakersfield, California (Figure 1). The regulatory contact for this project is Mr. Craig Perkins, Hazardous Materials Specialist, Bakersfield Fire Department, Fire Protection Services (BFD). a 2.0 BACKGROUND During the week of March 16, 2009, D 'N J Construction responded to the site in response to a request by Express Gas to identify why the asphalt and cement slab covering the UST was failing. Upon uncovering the 20,000-gallon gasoline"split" UST it was discovered that poor compaction appeared to have caused the slab U covering the UST to partially collapse,and a byproduct was that the settling caused the vapor line and product u line to pull apart from its fitting boots. The significance of the failed integrity of the vapor line and the potential for a release of gasoline to the subsurface was unknown,therefore, based on the site inspection conducted by a Bakersfield Fire Department, D 'N' J Construction, and AEC personnel it appeared necessary to conduct a limited subsurface assessment to evaluate the vertical extent of hydrocarbon impacted soil. 3.0 PHYSICAL CHARACTERISTICS D3.9 Site Description The Express Gas facility is located on the north side of Flower Street and south of Highway 178. The surrounding area is occupied by commercial and residential properties. The property is presently occupied by a convenience store and fueling system. D3.2 Site Hydrogeology 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 a 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 a 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 D 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. I a 1 • ENVIRONMENTAL CONCEPTS WITH DESIGN IN MIND a220 E. TRUXTUN AVENUE BAKERSFIELD, CA 93305 661/395-1646 FAX 661/395-1616 Soil Boring Report Advanced Environmental Concepts, Inc. 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 is 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. 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 Valley floor occurs within relatively unconsolidated continental deposits. The groundwater flow direction (gradient) beneath the site is estimated to be toward the southwest. Depth to first unconfined groundwater ranges between approximately 200 to 250-feet below ground surface(bgs)beneath the site area. However,"perched" water was identified in the sand which lies conformably on a silty clay layer between 15 and 20-feet bgs. 4.0 METHODS and PROCEDURES 4.1 Soil Borings On March 24, 2009 AEC supervised the drilling of the vertical and somewhat lateral definition soil borings. The two soil boring locations were placed as close to the visual release points from the vapor line 90 degree secondary containment boot and the product line 90 degree secondary containment boot. Because the tank and piping had been uncovered the closest that drilling could get to the release points was approximately 6 feet in distance. The soil borings were advanced by Global Probe using truck-mounted "Geoprobe" drilling and sampling equipment. Soil samples were collected using a spoon-type sampler fitted with an acetate 1 "macro" sleeve which collected 4-foot lengths of continuous core. Upon reaching the desired sampling depth the spoon sampler was driven into undisturbed soil using hydraulic hammering action. Following sample collection, the acetate sleeve was removed from the interior of the sampler and managed according to the following: the bottom portion of the sleeve was retained for laboratory analysis by placing Teflon-lined plastic caps over each end of the sleeve. An identifying label was affixed to the sleeve exterior,the sleeve was put in a plastic bag,then placed in an ice chest chilled to 4 degrees Celsius. The soil sample was recorded on a chain of custody document for transport to the laboratory. The middle portion of the sleeve was screened with the PID for volatile detections and 1 also studied for lithology descriptions. The information was recorded on the boring logs. Selected soil samples collected from the vertical and lateral definition borings were analyzed for TPH-as gasoline, and BTXE/MTBE by EPA Method 8015 and 8021 B. 5.0 ANALYTICAL RESULTS I The analytical results for the soil samples are presented in Table 1 and the analytical reports from the laboratory are in Appendix A. The units of analysis for the soil samples are in ug/kg (parts per billion). The analytical results indicate no detections above the Estimated Quantitation Limit(EQL)and only one detection of Toluene above the Method Detection Limit(MDL), therefore, is 'flagged" as a "J" value. The laboratory results correlated well with the field PID readings which were all"0".

From 21-feet to 25-feet bgs a silty clay was described (See the Boring Logs in Appendix B). Shallow soil in boring B-1 was saturated from 0.5 to 4-feet bgs and the soil samples collected in the sand lithology from 5-feet to 20-feet bgs were very moist. The water within the soil matrix was very cold and it is the opinion of AEC that there may be a slow water leak from a water line within the general area. The soil profile in B-2 consists of fine to coarse-grained sand to 18-feet bgs,which is underlain from 19-feet to 22-feet bgs by a silty clay. Beneath the clay from 23 to 25-feet bgs was a medium to coarse-grained sand. Groundwater was identified in the boring at approximately 15-feet bgs, again indicating that a water leak may be occurring in the general area. Because of the relative permeable nature of the subsurface lithology it was apparent that any hydrocarbon release would exhibit a strong tendency towards vertical migration, and only migrate laterally once the hydrocarbons reached a depth of approximately 21-feet bgs (silty clay) in B-1 and 18-feet bgs in B-2. Therefore, based on this migration assumption and knowing that the hydrocarbon release emanated in shallow soil beneath the piping connections of the vapor line and product line it can be concluded that the release is very recent and resulted from separation of the piping from the connective joints due to settling of the pea gravel and soil. Based on the information obtained from visual observation and from the drilling/analyses AEC believes that the gasoline released from the piping remains within the confines of the tank excavation and has not migrated vertically, or laterally. To confirm this, AEC recommends viewing the floor of the tank excavation following removal of the soil and pea gravel during the piping repair. 7.0 RECOMMENDATIONS AEC recommends that during the repair operation associated with the vapor and product lines that the floor of the tank excavation be viewed, and then potentially sampled. If the soil does not exhibit visual and olfactory ` signs of gasoline AEC will recommend"no further action". I 3 • ENVIRONMENTAL CONCEPTS WITH DESIGN IN MIND ' 220 E.

(AEC) to prepare this soil assessment work plan to investigate the vertical migration of gasoline-range hydrocarbons discovered when the underground storage tank (UST)was uncovered in response to a failing slab proximal to the UST. The service station is at 928 Flower Street, Bakersfield, California(Figure 1). The regulatory contact for this project is Mr. Craig Perkins, Hazardous Materials Specialist, Bakersfield Fire Department, Fire Protection Services(BFD). 1.1 Purpose The soil assessment program described in this work plan has the following objective: o Evaluate the vertical extent of gasoline migration proximal to the known release points at piping connections for the vapor recovery line. 1.2 Scope of Work The scope of services described in this work plan, are summarized below for clarification purposes. Detailed investigative methods are presented in Section 4.0 of this report: 1 1. Locating underground utilities using Client records and Underground Service Alert (USA); 2. Drilling two exploratory soil borings to evaluate the vertical extent of the assumed gasoline plume in the soil; 3. Collect soil samples at intervals of 5-feet commencing at 10-feet below ground 1 surface (bgs) using a spoon sampler lined with clean acetate sleeves. The soil samples will be field screened using a Photoionization Detector(PID)equipped with a 10.6 eV lamp; 1 4.

The report will be provided within 3-days of completion of the field work. 1 • ENVIRONMENTAL CONCEPTS WITH DESIGN IN MIND 220 E. TRUXTUN AVENUE BAKERSFIELD, CA 93305 661/395-1646 FAX 661/395-1616 Site Assessment Work Plan Advanced Environmental Concepts, Inc. 2.0 BACKGROUND During the week of March 16, 2009, D 'N J Construction responded to the site in response to a request by Express Gas to identify why the slab over the UST was failing. Upon uncovering the 20,000-gallon gasoline UST it was discovered that poor compaction appeared to have caused the slab over the UST to partially collapse, and a byproduct was that the settling caused the vapor line to pull apart from its fitting boots. The significance of the failed integrity of the vapor line and the potential for a release of gasoline to the subsurface is currently unknown. Therefore, based on the site inspection conduction by Bakersfield Fire Department, D'N'J Construction,and AEC personnel it appears necessary to conduct a limited subsurface assessment to evaluate the vertical extent of hydrocarbon impacted soil. ® 3.0 PHYSICAL CHARACTERISTICS ® 3.1 Site Description The Express Gas facility is located on the north side of Flower Street and south of Highway 178. The surrounding area is occupied by commercial and residential properties. The property is presently occupied by a convenience store and fueling system. 3.2 Site Hydrogeology 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 1 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. 2 • ENVIRONMENTAL CONCEPTS WITH DESIGN IN MIND 220 E. TRUXTUN AVENUE BAKERSFIELD, CA 93305 661/395-1646 FAX 661/395-1616 Site Assessment Work Plan Advanced Environmental Concepts, Inc. 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 is 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. 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 Valley floor occurs within relatively unconsolidated continental deposits. The groundwater flow direction (gradient) beneath the site is estimated to be toward the southwest. Depth to first unconfined groundwater ranges between approximately 200 to 250-feet below ground surface (bgs) beneath the site area. 4.0 WORK PLAID AEC proposes to advance two soil borings at the subject site and the location of the proposed borings are plotted on Figure 2. The vertical definition borings(13-1 and B-2)will be drilled to approximately 25-feet bgs, or to 10-feet below the bottom of the plume. 4.1 Drilling Methods The borings will be advanced using a Geoprobe rig. Prior to drilling,the rods will be steam cleaned to minimize any chance of affecting a potentially"clean" location. Soil sampling will be conducted at 5-foot intervals commencing at 10 feet bgs. Upon reaching the selected sampling interval, the sampler will be fitted with a two foot long acetate sleeve and driven ahead of the rods using hydraulic force. After driving the sampler to the required interval, it will be withdrawn from the hole and brought to the surface. The samples will be removed from the spoon, and the acetate sleeve will be immediately sealed with Teflon tape,capped, duct-taped, labeled, placed in a sealable plastic bag,and stored in a chilled ice chest for delivery to a State-certified laboratory. All soil samples will be recorded on a chain-of-custody document to ensure sample integrity and traceability. Soil lithology will be described from the cuttings and recorded on the boring logs in accordance with the Unified Soils Classification System (USCS). The soil in the sleeve will also be screened with a photoionization detector for total petroleum hydrocarbons. Prior to each sampling interval,the sampler will be washed in an Alconox solution and double-rinsed with clean, deionized water. 3 • ENVIRONMENTAL CONCEPTS WITH DESIGN IN MIND 220 E.

Its purpose is to provide established procedures to protect all on-site personnel from direct skin contact, inhalation,or ingestion of potentially hazardous materials that may be encountered at the site. The SSP establishes personnel responsibilities, personal protective equipment standards, decontamination procedures and emergency action plans. Advanced Environmental Concepts, Inc. seeks to enter the property described above for the purpose of conducting a site assessment. The work will consist of geoprobe boring and soil sampling in order to ' investigate hydrocarbon-impacted soil. Undisturbed soil samples will be collected to assess the extent of hydrocarbon impacted soil at the subject ' site. Each sample to be chemically analyzed will be collected in a brass sleeve,capped with lined plastic lids, sealed with tape, and immediately stored in a cooler with frozen Blue Ice immediately. All Chain-of-Custody protocol will be followed. ' Drilling equipment will be brought to the site and operated by: Global Geoprobe ' 71 San Marino Avenue Ventura, CA 93003 Contractor's License#C57-725397 ' This SSP describes the means for protecting all on-site personnel from deleterious contamination of personal injury while conducting on-site activities. As described below, we will strive to meet all requirements promulgated by the California Department of Health Services. ' Responsibilities of Key Personnel: All personnel on-site will have assigned responsibilities. Mr. Jonathan L. Buck will serve as Project Manager ' and on-site geologist: He will also serve as Site Safety Officer(SSO). As SSO, Mr. Buck will assure that on- site personnel have received a copy of the SSP. Personnel will be required to document their full understanding of the SSP before admission to the site. Compliance with the SSP will be monitored at all times ' by the SSO. Appropriate personal protective equipment, listed below,will be available and utilized by all on- site personnel. Prior to beginning work,the SSO will conduct a training session to assure that all are aware of safe work practices. In the training session, personnel will be made aware of hazards at the site. ' Mr. Buck will also be responsible for keeping field notes, collecting and securing samples, and assuring sample integrity by adherence to Chain-of-Custody protocol. I ' Health &Safety Plan Advanced Environmental Concepts, Inc. ' All on-site employees will take reasonable precautions to avoid unforeseen hazards. After documenting their understanding of the SSP, each on-site employee will be responsible for strict adherence to all points contained herein. Any deviation observed will be reported to the SSO and corrected. On-site employees are held responsible for performing only those tasks for which they believe they are qualified. Provisions of this ' SSP are mandatory and personnel associated with on-site activities will adhere strictly hereto. Job Hazard Analyses: ' Hazards likely to be encountered on-site include those commonly encountered when operating any mechanical equipment, such as the danger of falling objects or moving machinery. Simple precautions will reduce or eliminate risks associated with operating such equipment. A drilling contractor has been employed to deliver and operate all drilling equipment. Qualified personnel only will have any contact with this equipment. All on-site personnel, including the drilling contractor and his ' employees, are required to wear hard hats when in close proximity to drilling equipment. Latex sampling gloves will be worn by persons collecting or handling samples to prevent exposure to contaminants. Gloves will be changed between samples and used ones discarded,to avoid cross-contamination. Proper respiratory ' equipment will be worn if vapor contamination levels on-site exceed action levels as determined using a Photoionization Detector (PID). Action levels requiring respiratory apparatus will be 10-ppm-above background level in the breathing zone. Furthermore, no on site smoking, open flames or sparks will be permitted in order to prevent accidental ignition. ' Risk Assessment Summary: ' Exposure to chemicals anticipated on-site includes gasoline,diesel,and benzene,toluene,and xylene(BTX). These chemicals represent a hazard because they are moderately to extremely toxic and most are highly flammable. ' Threshold Limit Values(TLV's), Short Term Exposure Limits(STEL's)and Toxicity levels(LD50,oral-rat),all in mg/kg (ppm), are listed below: ' Compound TLV STEL Toxicity Gasoline 200 300 ---- Diesel 50 75 ---- ' Benzene 10 25 4894 Toluene 100 150 5000 Xylene 100 150 4300 ' Benzene is considered an extreme cancer hazard. Exposure Monitoring Plan: 1 A PID will be used to monitor vapor concentrations around the site. Should concentrations exceed TLV's, protective measures will be taken. Passive dosimeter badges will be placed in downwind locations if PID ' readings indicate high levels of volatile organics in the breathing space. Personal Protective Equipment: ' Personnel on-site will have access to respirators with organic vapor cartridges. Replacement cartridges will be available on-site as needed. When handling samples, the on-site Geologist will wear latex gloves. Hard hats will be worn by all personnel on-site when in proximity of drilling equipment. 2 I I I I ' Health & Safety Plan Advanced Environmental Concepts, Inc. ' Work Zones and Security Measures: Access to the site will be restricted to authorized personnel. A set of cones, placards, or wide yellow tape surrounding the site will define the perimeter, if needed. The Project Manager will be responsible for site security. Decontamination Measures: ' Avoidance of contamination whenever possible is the best method for protection. Common sense dictates that on-site personnel avoid sitting, leaning or placing equipment on possible contaminated soil.All personnel ' will be advised to wash their hands, neck and face with soap and water before taking a break or leaving the site. Respirators will be washed with soap and water following each day's use. Drilling and sampling equipment used will be decontaminated by steam-cleaning. Sampling equipmentwill be ' decontaminated before each sample is collected. General Safe Work Practices: On-site personnel will be briefed each day in "tailgate" meetings as to the day's goals and equipment to be used. Anticipated contaminants and emergency procedures will be reviewed. Appropriate personal protective equipment will be put on and verified correct by the SSO, including respirator fit. Drilling and sampling equipment will be steam-cleaned before arriving on-site. Split-spoon sampling equipment will be cleaned before each use. Augers will be steam-cleaned between borings. The on-site engineer will oversee operations and log borings.The Sample Coordinator will assure that proper protocol is used at all times in collecting and handling samples. ' Training Requirements: The SSO will conduct a "tailgate" training session before work begins which will include contaminant ' properties,warning signs, health hazard data, risk from exposure and emergency first aid. All chemicals are to be covered and the SSO will assure that everyone fully understands site hazards. ' Medical Surveillance Program: According to CFR 29, 1910.120, Paragraph (f), employees who wear respirators thirty (30) days or more during one(1)year or who have been exposed to hazardous substances or health hazards above established ' permissible exposure limits are required to be monitored medically. All site personnel are required to have had a complete physical (including blood chemistry)within the past year. ' Record Keeping: Documentation will be kept on personnel exposed to contaminant hazards on the job site according to OSHA regulations. These will include documentation that employees have received training on the SSP,respiratory ' protection, MSDS forms and all emergency procedures. These will be reviewed during the pre-work training meeting. ' Exposure records on each job will be kept for thirty(30)years to meet requirements. Included will be names and social security numbers of employees, medical evaluations, on-the-job logs from entry to exit, First Aid administered, visits on-site by outside persons and personal air-monitoring records.

Therefore,based on the site inspection conduction by Bakersfield Fire Department, D'N'J construction,and AEC personnel it appears necessary to conduct a limited subsurface assessment to evaluate the vertical extent of hydrocarbon impacted soil. 10 PHYSICAL CHARACTERISTICS 3.1 Site Description The Express Gas facility is located on the north side of Flower Street and south of Highway 178. The surrounding area is occupied by commercial and residential properties. The property is presently occupied by a convenience store and fueling system. 3.2 Site Hydrogeology The subject property is located in the southeastern end of the San Joaquin Valley where the Sierra Nevada,Great Valley, and Coastal Range physiographlc 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 Ban 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 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 60 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. 2 Mar. 20. 2009 3:53PM No. 0714 P. 5 Site Assessment Work Plan Advanced Environmental Concepts, Inc. 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 is 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. 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 Valley floor occurs within relatively unconsolidated continental deposits. The groundwater flow direction(gradient) beneath the site is estimated to be toward the southwest_ Depth to first unconfined groundwater ranges between approximately 200 to 250-feet below ground surface(bgs)beneath the site area. 4.0 WORK PLAN AEC proposes to advance two soil borings at the subject site and the location of the proposed borings are plotted on Figure 2. The vertical definition borings(8-1 and 8-2)will be drilled to approximately 25-feet bgs, or to 10-feet below the bottom of the plume. 4.1 Drilling Methods The borings will be advanced using a Geoprobe rig. Prior to drilling, the rods will be steam cleaned to minimize any chance of affecting a potentially"clean" location. Soil sampling will be conducted at 5-foot intervals commencing at 10 feet bgs. Upon reaching the selected sampling interval,the sampler will be fitted with a two foot long acetate sleeve and driven ahead of the rods using hydraulic force. After driving the sampler to the required interval,it will be withdrawn from the hole and brought to the surface. The samples will be removed from the spoon, and the acetate sleeve will be immediately sealed with Teflon tape,capped,duct-taped,labeled,placed in a sealable plastic bag,and stored in a chilled ice chest for delivery to a State-certified laboratory. All soil samples will be recorded on a chain-of-custody document to ensure sample integrity and traceability. Soil lithology will be described from the cuttings and recorded on the boring logs in accordance with the Unified Soils Classification System(USCS). The soil In the sleeve will also be screened with a photoionization detector for total petroleum hydrocarbons. Prior to each sampling interval,the sampler will be washed in an Alconox solution and double-rinsed with clean,delonized water. 4.2 Analytical Testing Soil samples collected during this project will be recorded on a chain-of-custody document and prepared for submittal to Associated Laboratories, Inc. a California-certified laboratory in Orange, California. The soil samples will be analyzed for Total Petroleum Hydrocarbons as gasoline and diesel by EPA 8015 modified;volatile organic compounds(benzene,toluene,ethyl benzene,and total xylenes); and MTSE by EPA Method 8021B. 3 I Mar. 20. 2009 3.53PM No. 0714 P. b Site Assessment Work Plan Advanced Environmental Concepts, Inc. 5.0 REMARKS/SIGNATURES This work plan represents Advanced Environmental Concepts,Inc.'s professional opinions.

Suck California Professional Geologist##7468 J-ExpressGaawp 4 Mar. 20. 2009 3:53PM No. 0714 P. 7 Health & Safety Plan for Express Gas Mini Mart 928 Flower Street County of Kern•Bakersfield,California Introduction: A Site Safety Plan (SSP) has been designed to address safety provisions needed during the site soil assess ment/remediation. Its purpose is to provide established procedures to protect all on-site personnel from direct skin contact,Inhalation,or Ingestion of potentially hazardous materials that may be encountered at the site. The SSP establishes personnel responsibilities, personal protective equipment standards, decontamination procedures and emergency action plans. Advanced Environmental Concepts, Inc. seeks to enter the property described above for the purpose of conducting a site assessment. The work will consist of geoprobe boring and soil sampling in order to investigate hydrocarbon-impacted soil. Undisturbed soil samples will be collected to assess the extent of hydrocarbon Impacted soil at the subject site. Each sample to be chemically analyzed will be collected in a brass sleeve,capped with lined plastic lids, sealed with tape, and immediately stored in a cooler with frozen Blue Ice immediately. All Chain-of-Custody protocol will be followed. Drilling equipment will be brought to the site and operated by: Global Geoprobe 71 San Marino Avenue Ventura,CA 83003 Contractor's License#C57-725397 This SSP describes the means for protecting all on-site personnel from deleterious contamination of personal injury while conducting on-site activities. As described below, we will strive to meet all requirements promulgated by the California Department of Health Services. Responsibilities of Key Personnel: All personnel on-site will have assigned responsibilities. Mr.Jonathan L. Buck will serve as Project Manager and on-site geologist. He will also serve as Site Safety Officer(SSO), As SSO,Mr.Buck will assure that on- site personnel have received a copy of the SSP. Personnel will be required to document their full understanding of the SSP before admission to the site. Compliance with the SSP will be monitored at all times by the SSO. Appropriate personal protective equipment, listed below,will be available and utilized by all on- site personnel. Prior to beginning work,the SSO will conduct a training session to assure that all are aware of safe work practices. In the training session, personnel will be made aware of hazards at the site, Mr. Buck will also be responsible for keeping field notes, collecting and securing samples, and assuring sample integrity by adherence to Chain-of-Custody protocol. Mar- 20. 2009 3:53PM No. 0714 P. 8 Health &Safety Plan Advanced Environmental Concepts, Inc. All on-site employees will take reasonable precautions to avoid unforeseen hazards. After documenting their understanding of the SSP, each on-site employee will be responsible for strict adherence to all points contained herein. Any deviation observed will be reported to the SSO and corrected. On-site employees are held responsible for performing only those tasks for which they believe they are qualified. Provisions of this SSP are mandatory and personnel assoclated.with on-site activities will adhere strictly hereto. Job Hazard Analyses: Hazards likely to be encountered on-site include those commonly encountered when operating any mechanical equipment, such as the danger of falling objects or moving machinery. Simple precautions will reduce or eliminate risks associated with operating such equipment. A drilling contractor has been employed to deliver and operate all drilling equipment. Qualified personnel only will have any contact with this equipment. All on-site personnel, including the drilling contractor and his employees, are required to wear hard hats when in close proximity to drilling equipment. Latex sampling gloves will be worn by persons collecting or handling samples to prevent exposure to contaminants. Gloves will be changed between samples and used ones discarded,to avoid cross-contamination. Proper respiratory equipment will be worn if vapor contamination levels on-site exceed action levels as determined using a Photolonization Detector (PID). Action levels requiring respiratory apparatus will be 10-ppm above background level in the breathing zone. Furthermore, no on-site smoking, open flames or sparks will be permitted in order to prevent accidental ignition. Risk Assessment Summary: Exposure to chemicals anticipated on-site includes gasoline,diesel,and benzene,toluene,and xylene(STX). These chemicals represent a hazard because they are moderately too extremely toxic and most are highly flammable. Threshold Limit Values(TLV's),Short Term Exposure Limits(STEL's)and Toxicity levels(LD50,oral-rat),all In mg/kg(ppm), are listed below, Compound TLV STEL Toxicity Gasoline 200 300 ---- Diesel 50 75 ---- Benzene 10 25 4894 Toluene 100 150 5000 Xylene 100 150 4300 Benzene is considered an extreme cancer hazard. Exposure Monitorintl Plan: A PID will be used to monitor vapor concentrations around the site. Should concentrations exceed TLV's, protective measures will be taken. Passive dosimeter badges will be placed in downwind locations if PID readings indicate high levels of volatile organics in the breathing space. Personal Protective Equipment: Personnel on-site will have access to respirators with organic vapor cartridges. Replacement cartridges will be available on-site as needed. When handling samples,the on-site Geologistwill wear latex gloves. Hard hats will be worn by all personnel on-site when in proximity of drilling equipment. 2 Ma r. 20. 2009 3:54PM No. 0714 P. 9 Health&Safety Plan Advanced Environmental Concepts, Inc. Work Zones and Security Measures: Access to the site will be restricted to authorized personnel. A set of cones, placards, or wide yellow tape surrounding the site will define the perimeter, if needed. The Project Manager will be responsible for site security. Decontamination Measures: Avoidance of contamination whenever possible is the best method for protection. Common sense dictates that on-site personnel avoid sitting,leaning or placing equipment on possible contaminated soil.All personnel will be advised to wash their hands, neck and Face with soap and water before taking a break or leaving the site. Respirators will be washed with soap and water Following each day's use. Drilling and sampling equipment used will be decontaminated bysteam-cleaning. Sampling equipment will be decontaminated before each sample is collected. General Safe Work Practices: On-site personnel will be briefed each day in"tailgate"meetings as to the day's goals and equipment to be used. Anticipated contaminants and emergency procedures will be reviewed. Appropriate personal protective equipment will be put on and verified correct by the SSO, including respirator fit.. Drilling and sampling equipment will be steam-cleaned before arriving on-site. Split-spoon sampling equipment will be cleaned before each use. Augers will be steam-cleaned between borings. The on-site engineer will oversee operations and log borings.The Sample Coordinator will assure that proper protocol is used at all times in collecting and handling samples. Training Requirements: The SSO will conduct a "tailgate" training session before work begins which will include contaminant properties,warning signs,health hazard data,risk from exposure and emergency first aid. All chemicals are to be covered and the SSO will assure that everyone fully understands site hazards. Medical Surveillance Program: According to CFR 29, 1910.120, Paragraph (f), employees who wear respirators thirty (30) days or more during one(1)year or who have been exposed to hazardous substances or health hazards above established permissible exposure limits are required to be monitored medically. All site personnel are required to have had a complete physical(including blood chemistry)within the past year. Record Keeping: Documentation will be kept on personnel exposed to contaminant hazards on the job site according to OSHA regulations. These will include documentation that employees have received training on the SSP,respiratory protection, MSDS forms and all emergency procedures. These will be reviewed during the pre-work training meeting. Exposure records on each job will be kept for thirty(30)years to meet requirements. Included will be names and social security numbers of employees, medical evaluations, on-the-job logs From entry to exit, First Aid administered, visits on-site by outside persons and personal air-monitoring records. 3 Ma r. 20. 2009 3:54PM No. 0714 P. 10 Health &Safety Plan Advanced Environmental Concepts, Inc.
