(RAM) is pleased to present this Revised Site Investigation Workplan for the JACO OIL owned Fastrip (# 773) self-serve gas station and convenience store. This gas station is located at 3501 Mt. Vernon Avenue, ' Bakersfield, California (Site), (see Figure 1 for an Area Map and Figure 2 for a Plot Plan of the Site). Soil samples were collected from beneath piping that was being replaced at the Site on May 6, 2008, analytical results of these samples showed that soil 20 inches below the south end of the piping was impacted with hydrocarbons. A report summarizing the soil ' sampling and analytical results was submitted to the Bakersfield Fire Department(BFD), Prevention Services Division for review on June 2, 2008. Based on their review, the BFD issued a letter on June 17,2008 (see Attachment A—BFD Correspondence), which ' requested a workplan for further investigation of soils beneath the pipe. A Site Investigation Workplan was submitted to BFD by RAM on July 18, 2008. On August 25,2008 BFD responded to the Site Investigation Workplan and requested a Revised Site Investigation Workplan to include a third boring to define the subsurface hydrocarbon plume. This Revised Site Investigation Workplan is being submitted in response to the BFD August 25, 2008 letter to Jaco Oil Company. ' RAM proposes to advance three borings at the site, using a hollow-stem auger, to evaluate the vertical and horizontal extent of the petroleum impacted soils. Soil samples will be collected at 5-foot intervals. Selected soil samples will be analyzed by a 1 California state certified laboratory for Total Petroleum Hydrocarbons as gasoline (TPHg); Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX); and fuel oxygenates. ' This Site Investigation Workplan follows the guidelines presented in Appendix A Reports,Tri-Regional 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 Engineering Services, Inc., Richard Casagrande or Jane McNaboe, 2115 20th Street, Bakersfield, California, 93301, telephone (661) 324-6152, FAX (661) 324- 6172. ' R:\2000-08\370—revised SI_Workplan_3501 Mt.Vernon Ave.doc 2 3501 Mt.Vernon Avenue,Bakersfield RAM Environmental Engineering,Inc. Project#200370 Revised Site Investigation Workplan ' August 2008 1.2 Site History ' On May 6, 2008 RAM conducted soil sampling at the Fastrip market and gas station located at 3501 Mt. Vernon, Bakersfield, California(Site), as noted in Figure 1,Area Map. Soil samples were taken from beneath piping that was being ' replaced. The sampling was conducted to assess the potential presence.of petroleum hydrocarbons in soils beneath former piping at the station as the equipment was modified under Bakersfield Fire Department(BFD) Permit to Modify Underground Storage Facility, permit number MD0407. An excavation was developed to expose and replace piping leading from the ' USTs to the dispenser islands, as shown on Figure 2,Proposed Borings. The underlying soils were sands, clays and gravels. Soil samples were taken under the direction of BFD from below the former piping at the ends and in the center of the ' piping run. The soil samples were collected from between 9 inches and 20 inches below the excavation. It was not possible to obtain deeper samples due to the ' gravel in the soil. A summary of soil sample analytical results is presented in Table 1 following the text, and on Figure 2,Proposed Borings. In the soil sample collected from below the south end of the piping,hydrocarbons were detected as follows. Sample 1-20"S Soil sample 1-20" S, collected from 20 inches below the south end of the piping contained significant concentrations of benzene, toluene, ethylbenzene, xylenes 1 and TPH-g. The key points of this sample's analytical results are: • the concentration of benzene in the soil, 1,600 gg/Kg, exceeds the PRG for industrial soil of 1,400 µg/Kg, and the LUFT value of 1,000 µg/Kg(1 mfg), • the concentrations of toluene, ethylbenzene, and xylenes exceed the LUFT ' values but do not exceed the PRG's, and • the concentration of TPH-g exceeds the LUFT value. No PRG value has been established for gasoline. R:\2000_08\370_revised SI_Workplan_3501 Mt.Vernon Ave.doc 3 3501 Mt. Vernon Avenue, Bakersfield RAM Environmental Engineering,Inc. Project#200370 Revised Site Investigation Workplan August 2008 ' 2.0 INVESTIGATION PURPOSE AND SCOPE The objective of the proposed Site Investigation is to: • define the vertical and horizontal extent of hydrocarbon impacted soils within the proximity of the known pipe leak; • obtain certified analytical data on hydrocarbon concentrations in soil samples; • if groundwater is encountered, collect grab samples for analysis of potential ' impacts from the fuel leak; • evaluate the Site Investigation results to determine if further investigation or remediation is necessary; and • present the findings of the Site Investigation and recommendations to the BFD. To meet these objectives,the Site Investigation will include the following tasks: • obtain BFD approval of this Workplan and attached Health and Safety Plan .(Attachment B); • sample soils at five-foot intervals from three borings drilled with a hollow-stem auger to evaluate the extent of hydrocarbon containing soils at the Site; • record soil characteristics and field PID measurements in field boring logs; ' • analyze selected soil samples for TPH-g, BTEX; and fuel oxygenates; • evaluate findings of the investigation; and • report Site Investigation results, evaluations, and recommendations for further ' action to BFD. ' 3.0 SITE DESCRIPTION 3.1 Site Description Currently, the Jaco Owned Fastrip mini-market and self-serve gas station operate on the Site. The gas station distributes gasoline from 2 dispenser islands with 2 dispensers per island and 3 underground storage tanks (USTs), consisting of one ' 12,000-gallon regular unleaded gasoline, one 12,000-gallon premium gasoline, and one 12,000-gallon diesel UST. The service station is located on the northeast corner of the intersection of Mt. Vernon Avenue and University Avenue in ' Bakersfield, California. Adjacent to the service station to the south is a residential area, and to the north east and west are parking areas associated with the adjacent Bakersfield College. 4.0 TOPOGRAPHY,GEOLOGY AND HYDROGEOLOGY 4.1 Topography The Site is at an elevation of approximately 700-feet above sea level. The topography slopes moderately to the southwest (see Figure 1—Area Map). 4.2 Geology The Site is located in the San Joaquin Valley, which is the southern portion of the 1 Great Valley geomorphic province. The Great Valley is a large alluvial plain iRA2000_08\370_revised SI_Workplan_3501 Mi.Vemon Ave.doc 4 3501 Mt.Vernon Avenue,Bakersfield RAM Environmental Engineering,Inc. Project#200370 Revised Site Investigation Workplan ' August 2008 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 outcrop along most of the eastern and southeastern flanks of the Great Valley, while marine rocks of pre- ' Tertiary age outcrop 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 u pp ermost sedimentary ry units in the vicinity of the Site are Quaternary, Recent-fan deposits. Subsurface soils at the site are expected to be sands containing gravels and cobbles. 4.3 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 located approximately 4,700 feet to the northwest. There are no surface waters in the immediate Site area. The regional unconfined ' groundwater at the Site is at approximately 480 feet below ground service (bgs); the groundwater flows to the north (KCWA 2004). 4.4 Past leak, 1994 A survey of Leaky Underground Fuel Tank(LUFT) sites in the area on the California State Water Resources web site"GeoTracker" shows that a leak was discovered at the Site in 1994. According to Mr. Craig Perkins of the BFD,the leak was a"non-petroleum spill". The case was closed in 1995. ' 4.5 Public drinking water wells The Kern County Water Agency map of Water Wells and Spreading Areas (April 2004,Plate 3) shows no water wells in the Site vicinity. ' 5.0 QUANTITY OF CONTAMINANT RELEASED The quantity of contaminant released is unknown. ' R:\2000_08\370_revised SI_Workplan_3501 Mt.Vernon Ave.doc 5 ' 3501 Mt. Vernon Avenue,Bakersfield RAM Environmental Engineering,Inc. Project#200370 Revised Site Investigation Workplan tAugust 2008 6.0 STRATEGY AND PROCEDURES FOR SITE INVESTIGATION The goal of this site investigation will be to develop one boring as close as possible to the impacted soils below the piping and two borings to the south and southwest of the first boring. As the leak from the piping is located above the underground tanks, it will not be possible to develop a boring in the same location of the preliminary soil samples (see Figure 3,Proposed Borings). . Soil samples will be collected at five foot intervals progressing vertically below any hydrocarbon impacted soil encountered until two consecutive soil samples have been tcollected that show no field detectable signs of hydrocarbon impacts. Prior to any intrusive methods being conducted at the Site, USA of Northern California will be utilized to map out the underground utilities at the Site. Based on.the clearances obtained, RAM will site the soil borings in safe locations. ' 6.1 Sample Collection To assess the vertical extent and horizontal extent of impacted soil RAM will advance three (3) soil borings (borings B-1 through B-3)with a hollow-stem auger. The borings will be hand augered to a depth of 5 feet before advancing the hollow-stem auger. Boring B-1 will be located as close as possible to the known ' hydrocarbon impacted soil (see Figure 3,Proposed Borings). Borings B-2 and B-3 will be located down-slope from the known impacted soil, avoiding the overhead power lines at the Site. All borings will be deepened to 10 feet below ' the lowest field detectable volatile organic compounds (VOCs) and/or visible staining, or to the depth of the groundwater, if encountered, or until drilling refusal is encountered. A PID model Photovac 2020, 10.6 eV UV lamp will be used to test for the presence of VOCs. Soil samples will be collected at 5 foot intervals, beginning at 10 feet below ground surface (bgs), the soil samples will be field screened with a PID, and described by a State of California Professional Geologist. A lithologic log of each soil boring will be generated. Soils will be described and classified according to the Unified Soils Classification System (USCS); observations of soil staining or discoloration will be included on the lithologic log. Soil sampling will proceed according to the soil sampling plan (Attachment Q. Groundwater is not expected to be encountered. ' R:\2000_08\370_revised SI_Workplan_3501 Mi.Vemon Ave.doc 6 ' 3501 Mt.Vernon Avenue,Bakersfield RAM Environmental Engineering,Inc. Project#200370 Revised Site Investigation Workplan ' August 2008 ' 6.2 Analytical Methods Soil samples will be handled according to RAM's Soil Sampling Plan, which is included in Attachment C. The samples will be labeled, stored in an ice cooler ' cooled with blue ice and then transported to CalScience Laboratory at the end of the working day. The soils will be analyzed as follows: ' • Total petroleum hydrocarbons as gasoline (TPH-g, carbon range C 6- C 10)by EPA Method 8015M, ' • Total petroleum hydrocarbons as diesel (TPH-d, carbon range C lo- C 28)by EPA Method 8015M, ' • Benzene,Toluene,Ethyl-benzene and Xylene (BTEX) by EPA Method 8260B, and ' • Oxygenates, t-Butanol (TBA) Tert-Butyl Alcohol, Methyl Tert-Butyl Ether(MTBE),Diisopropyl Ether(DIPE), Ethyl Tert-Butyl Ether(ETBE), ' Tert-Amyl Methyl Ether(TAME); by EPA Method 8260B . 6.3 Boring Closure ' When the total depth of the boring is reached, as determined in the field from observations,the boring will be backfilled with cement grout. The surface will be compacted and covered with cement or asphalt to match existing grade. ' 6.4 Work Schedule The Site Investigation will begin within 45 days after the workplan has been accepted by BFD, and after all permits are obtained. Jaco prefers to schedule the work at the same time as the work to be conducted at the Howard's mini-mart on Planz Road. BFD will be notified approximately 48 hours before fieldwork ' commences. 'A Site Investigation Report will be submitted to BFD approximately 45 days after completion of the Site Investigation and receipt of analytical data. ' 7.0 WASTE MANAGEMENT Drill cuttings (soil) generated by drilling soil borings will be placed in labeled drums and left on-site. The drum contents will be properly managed after soils laboratory analyses ' have been received, and the waste has been profiled. 1 1 ' R:\2000_08\370_revised SI_Workplan_3501 Mi.Vemon Ave.doc 7 3501 Mt.Ve rn on Avenue,Bakersfield RAM Environmental Engineering,Inc.

(RAM), as primary contractor for this project, has prepared this Site-Specific Health and Safety Plan (HASP). The HASP ' delineates the basic safety requirements for the implementation of the soil sampling at the service station located at 3501 Mt. Vernon. Avenue, Bakersfield, California. Work at the site will include collection of soil samples using a hollow-stem auger, vapor sampling ' during soil sampling using a Photo-ionization Detector (PID) or equivalent equipment, and delivery of soil samples for chemical analysis. The fieldwork is scheduled to be performed within 45 days of approval by the Bakersfield Fire Department. The provisions set forth in this HASP apply to the employees of RAM and their subcontractors working on project tasks, which expose workers to hazardous working ' conditions, to dust, hazardous wastes, or hazardous substances. Subcontractors may elect to modify these provisions, but only to upgrade or increase the safety activities to be ' consistent with their company policies. This HASP addresses the expected potential hazards that may be encountered for this ' project. If unanticipated changes in site or working conditions occur which are not addressed by this plan,'addenda will be provided by RAM.. 1.1 SITE BACKGROUND 1 The project consists of one service-station (Site) in Bakersfield, California. ' 1.2 SCOPE OF WORK The objective of this scope of work is to sample soils in the area of a piping replacement ' project to determine if the extent of soils containing hydrocarbons. 1 1 tR:\2000_08\370_revised S1 worplan_H&S Plan.doc •2L 1 . 2.0 PROJECT SAFETY AUTHORITY ' Personnel responsible for project safety are the Project Manager and the Site Safety Officer or his designee. ' The Project Manager is responsible for the provisions and submittal of this plan, and for J g P p advising the Site Safety Officer on health and safety matters. The Project Manager has ' the authority to provide for the auditing of compliance with the provisions of this plan, suspension or modification,of work practices, and administration of disciplinary actions' for individuals whose conduct does not meet the requirements set forth herein. The ' Project Manager may elect to give the Site Safety 'Officer authority to administer disciplinary actions for individuals whose conduct does.not meet the requirements set forth herein. The Site Safety Officer is responsible for the dissemination of the information contained ' in this plan to all REBRAC personnel assigned to the project, and to the!"responsible representative.of each subcontractor firm working under REBRAC on the project. As such,he or she is responsible for performing or providing the following as necessary: • Adequate on-site safety- supplies & equipment' inventory (see list of ' protective equipment, Sec. 8.0), for RAM personnel. Compliance for having necessary Safety Supplies and Equipment rests solely with each subcontractor, • tailgate discussion of Site Safety Plan; documentation of tailgate safety meetings in field notebook, 1 ' • documentation of all accidents or safety plan violations, 0 emergency contacts as needed,, g Y ' 0 implementation of Decontamination/Contamination Reduction Procedures (see Sec. 9.0), ' on.-site air monitoring as required (see Section 6.0). ' The Site Safety Officer or his/her designee has the authority to suspend work any time he or she determines that the health and safety practices at the site are inadequate and shall also inform the Project Manager of individuals whose conduct is not consistent with the ' requirements of the plan. ' R:\2000_08\370_reviscd SI worplan_H&S Plan.doc 3 3.0 MEDICAL SURVEILLANCE ' RAM personnel and sub-contractors engaged in project operations that may expose them to hazardous wastes, hazardous substances, or any combination of hazardous wastes or ' hazardous substances shall be participants in a Medical Surveillance program, and must be cleared by the examining physician(s) to wear respiratory protection devices and protective clothing for working with hazardous materials. The applicable requirements ' under the CAL OSHA standard for Hazardous Waste Operations and Emergency Response (Title 8 CCR, GISO 5192) will be observed where potential hazardous wastes .are encountered. ' 4.0 SAFETY/ORIENTATION TRAINING }. Field personnel from RAM and any subcontractors will review this site-specific Health ' and Safety Plan (HASP) before beginning work as safety training for this project. The Site Safety Officer will conduct a tailgate safety meeting to review the HASP prior to the ' start of field operations. RAM project personnel will certify their review by signing a HASP training'record form (Appendix B). _ Subcontractors will certify their review by signing a HASP training record form or signing the field notebook after the tailgate safety, ' meeting. The Project Manager is responsible for distributing this site safety plan to appropriate personnel and verifying review by obtaining signed review forms. Signed review forms will be placed in project files. ' Whenever a that change of conditions on-site occurs e g at ma y affect safety, the Site Safety . ' Officer or his/her designee will conduct a tailgate safety meeting if appropriate. Changing site conditions.that may affect safety include the following: ' Change of field personnel (RAM or subcontractor), ' change in work activity, • change in weather conditions; and, ' visitors on site. ' All training sessions, safety meetings, and safety briefings will be documented by the Site Safety Officer or his designee in the field notebook. Documentation will include a brief ' description of topics addressed and the signatures of all training attendees. ' R:\2000-08\370—revised Sl worplan_H&S Plan.doc 4 . 5.0 HAZARD ASSESSMENT 5.1 PHYSICAL HAZARDS Working with drilling equipment 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, t • exposure to noise generated by heavy machinery, • exposure to soil dust generated by heavy machinery, • insufficient or faulty protective equipment; and insufficient or faulty operations, equipment, or tools, ' ' • 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 exposures; however, this section is included as a precautionary measure. It is most likely that the hazard at this site will be from refined products found during the sampling of the soil. Specific precautions will be taken as the situations at each of the sites dictate. Following is a discussion of the ' chemical hazards of petroleum hydrocarbons. ' RA2000_08\370_revised S1 worplan_H&S Plan.doc 5 ' 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, BTEX 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 BTEX (Appendix Q. 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 and 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 which present potential inhalation exposures 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 drilling activities. 5.3 EXPLOSION AND FIRE ' The types of hydrocarbons expected to be present 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 ' R:\2000-08\370—revised S1 worplan_H&S Plan.doc 6 a i (>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. iTable 1. OSHA PELs and ACGIH TLVs for Aromatic Volatile,Organic Compounds. OSHA PELs ACGIH TLVs ' a b a b Compound TWA STEL TWA STEL (ppm) m)'= (ppm) m ' Benzene 1 5 10 Toluene , 100 150 100 150 Ethyl benzene 100 125 100 125 ' (o-,m-,p-X lene isomers 100 150 100 150 Y ) a - . TWA: Time weighted average is the employees average airborne exposure in any 8 hour work shift of a 40-hour work week which shall not be exceeded. b STEL: Short term exposure limit is the employee's 15-minute time weighted average ' airborne exposure which shall not be exceeded at any time during a work day. 6.0 AIR-MONITORING An organic vapor analyzer (OVA) with a flame-ionization detector (FID) or Hnu ' photoionization detector (PID) will be ,used to conduct air monitoring during activities where potential for airborne exposure exist, specifically during soil sampling. During soil sampling, 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 ' R:\2000-08\370—revised SI worplan_H&S Plan.doc 7 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.

' 7.2 SYMPTOMS OF CHEMICAL ExP OSURE Chemical exposure is not anticipated. The information below is provided as a precautionary measure. . Field operations personnel, shall inform each other. of non-visual 1 symptoms that may indicate chemical exposure such as: • Headaches, ' 0 dizziness, ' R:\2000-08\370—revised SI worplan_H&S Plan.doc 10 1 ' ' nausea,. • blurred vision, ' 0 cramps, • coughing, irritation of eyes, skin, or.respiratory tract,. • changes in complexion or skin discoloration, g p . ' 0 changes in apparent motor coordination, ' 0 changes in personality or demeanor, • excessive salivation or changes in papillary response; and • changes in speech ability or pattern. 1 ' ' 7.3 HEAT STRESS The following recommendations will help to reduce heat stress: • Provide plenty of liquids, ' 0 wearing of an undergarment that acts to help ventilation of the body, ' 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 1 100 at the next'rest period, the following work cycle should be shortened by 33%, ' R:\2000-08\370—revised Sl worplan_H&S Plan.doc 11 body temperature can be used to screen for heat stress. if the -oral temperature at the beginning of the rest 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. Thiscprocess should be continued until the body temperature does not exceed 99 F, • body water loss can be monitored using a scale to measure changes in ' body weight. t8.0 PROTECTIVE EQUIPMENT REQUIREMENTS Field personnel and visitors are required to wear hard hats, safety glasses; steel-toed boots, and hearing. protection (at the discretion of the Site Safety Officer) in the operations area when work is being performed. Field personnel engaged in work operations are required to wear the following additional equipment if unknown chemicals of concern are encountered: • Long-sleeved . shirts and- pants' or one-piece coverall, such as Tyvek ' disposable, • poly-coated Tyvek suit (when contact with potentially contaminated material is anticipated), ' rubber boots (when contact with potentially contaminated soil or liquid is anticipated), • orange safety vests, ' all personnel shall be required to wash hands and face before eating or drinking, ' personnel are not required to wear protective dust masks. Therefore, personnel shall be required to avoid-breathing dust on site at all times, and work upwind.. Contractors to RAM will provide their own PPE. ' R:\2000_08\370_revised SI worplan_H&S M6.doc 12 8.1 OPERATIONS AREA Dermal contact will be the potential exposure pathway of concern for chemical exposure. Inhalation exposure will only be a significant concern when dusty conditions or organic ' vapors are present. ' Protective clothing, including Tyvek suits, rubber boots, and chemically resistant gloves such as nitrile, will be mandatory for all field operations personnel when contacting potentially contaminated soils. When the ambient air monitoring level,equals or exceeds 5 ppm, full or half-face APR's with organic vapor cartridges will be required. Personnel should approach any unknown substances from upwind. 9.0 DECONTAMINATION/CONTAMINATION REDUCTION PROCEDURES ' Che mi cal exposure is not anticipated at this Srte. This section is included so that procedures are established in the event that unknown chemicals arepresent at the Site. ` Boots, clothing, gloves, and other equipment can become contaminated by direct exposure to contaminated soil or groundwater. Precautions-will be taken to prevent the transport of contaminants off site unless in an approved container or other approved method. All contaminated personal protective equipment or clothing will be ' decontaminated on=site, or placed in appropriate storage or disposal receptacles. ' 10.0 EMERGENCY RESPONSE PROCEDURES A first aid kit, will be taken into the field each day. In the event of a fire, explosion, physical injury or illness due to chemical exposure, the appropriate parties should be contacted using the below listed phone numbers. For injuries or illness other than very ' minor cuts or scrapes,'a physician's attention is required. For treatment of potentially life-threatening injury or illness,call 911 for assistance. For treatment of minor injuries or illness, personnel should be driven to Bakersfield Memorial Hospital, 420 34`h Street, Bakersfield, CA.

Vernon Project#200370 ' May 2008 1.0 INTRODUCTION On May 6, 2008 RAM Environmental Engineering Services, Inc. (RAM)conducted soil sampling at the Fastrip market and gas station located at 3501 Mt. Vernon, Bakersfield, California(Site), as noted in Figure 1,Area Map. Soil samples were taken from beneath piping that was being replaced. The sampling was conducted to assess the potential presence of petroleum hydrocarbons in soils beneath former piping at the station as the ' equipment was modified under Bakersfield Fire Department (BFD)Permit to Modify Underground Storage Facility,permit number MD0407 (see Appendix A for a copy of the Permit). This report describes the field procedures, observations, and findings, and ' results of the laboratory analysis of soil samples collected at the Site. Currently,the Jaco Owned Fastrip mini-market and self-serve gas station operate on the ' Site. The gas station distributes gasoline from 2 dispenser islands with 2 dispensers per island and 3 underground storage tanks (USTs), consisting of two 13,000-gallon regular unleaded gasoline, and one 13,000-gallon premium gasoline UST. The service station is ' located on the northwest corner of the intersection of Mt. Vernon Avenue and University Avenue in Bakersfield, California. Adjacent to the service station to the south is a ' residential area, and to the north east and west are parking areas associated with the adjacent Bakersfield College. ' The excavation area was below piping leading from the.USTs to the dispenser islands, as shown on Figure 2,Sample Location Map,and in the photographs in Appendix E. The underlying soils were sands, clays and gravels. Samples were taken under the direction ' of BFD from below the former piping at the ends and in the center of the piping run. The soil samples were collected from between 9 inches and 20 inches below the excavation. It was not possible to obtain deeper samples due to the gravel in the soil. The scope of work for this investigation was developed in conversation with Mr. Ed Carpio of Sunset Construction, Mr. Howard Wines of the BFD, and follows the KCEHSD U.T. 30 "Soil Sampling Guidelines for Underground Storage Tanks," and US EPA, SW 846, 3`d Edition. ' 2.0 SOIL SAMPLING 2.1 Pre-Field Investigation ' Prior to work at the Site, a Sampling Plan (Appendix B) and a Site Safety Plan (Appendix C) were prepared. The sampling and safety plans were reviewed in the field prior to the start of sampling with a representative of BFD. The specific ' sampling plan for this work was developed using RAM's standard procedures for soil sampling and is included in Appendix B. A site layout was reviewed and proposed sampling sites were selected and numbered (see Figure 2,Sample ' Location Map)prior to the sampling. The approximate depth to groundwater below the Site is 400 feet below ground surface (bgs), and the groundwater flow direction is towards the northwest (Kern ' R:\2000_08\370_soil rpt_Mt vemon.doc 2 Fastrip,3501 Mt.Vernon Project#200370 May 2008 County Water Agency, 2004). No municipal water wells are located near this Site ' (Geotracker, 2008). The service station discovered a gasoline leak in December 1994, the leak was reported and the case was closed in 1995. ' 2.2 Soil Sampling Samples were obtained from soils gathered using a hand auger. Undisturbed soil samples were collected in 2-inch by 3-inch brass sleeves by extracting soil from ' the auger. Sample sleeves were then sealed with Teflon and plastic caps. All samples were double-bagged and placed on ice. A PID model Gas Alert/Micro 5, 10.6 eV UV lamp,was used to test for emissions of organic vapors collected in ' the void left when the brass sleeve was removed from the bucket soils. Results were recorded in field notes. ' Sampling was conducted on May 6, 2008 using the site-specific sampling plan (Appendix B). Three soil samples were collected at depths ranging from between 9 inches and 20 inches below the former piping (Figure 2,Sample Location Map). The soil samples were collected below the piping at the south end,the north end and the center of the excavation. It was not possible to collect the soil samples from the recommended depth of 6-feet below the pipeline due to gravels ' in the soil. ' 2.3 Laboratory Analysis All the samples collected were labeled, recorded on chain-of-custody forms, placed in an ice chest cooled to 4°C, and transported.to the laboratory under standard chain-of-custody protocol. Samples were analyzed for the following ' constituents using EPA approved methods: • Total petroleum hydrocarbons as diesel (TPHd,carbon range C 12_C 24) using EPA Method 8015M; ' • Total petroleum hydrocarbons as gasoline (TPHg, carbon range C4—C11) using EPA Method 801513; ' • Benzene, toluene, ethylbenzene, xylenes (BTEX) using EPA Method 8260B. ' • Five fuel oxygenates methyl tert-butyl ether(MTBE), Tert-Butyl Alcohol (TBA), Diisopropyl Ether(DIPE), Ethyl-t-Butyl Ether(ETBE), and Tert- Amyl-Methyl Ether(TAME) by EPA Method 8260B. ' Calscience Environmental Laboratories, Inc., a California state certified laboratory,performed the above analyses. R:\2000_08\370_soil rpt_Mt vemon.doc 3 Fastrip,3501 Mt. Vernon Project#200370 May 2008 ' 3.0 FINDINGS 3.1 Photo-ionization detector A photo-ionization detector(PID) was used during sampling to monitor for ' volatile hydrocarbons released from the soil. The PID is calibrated with select gasoline hydrocarbons at the parts per million (ppm) level. Detection of other volatiles not included in the calibration mix provides a relative indication of the presence of volatile organics. The PID did not measured volatile hydrocarbons in the soil samples. 3.2 Analytical Results The analytical results are summarized in Section 4.0, Table 3-1 (page 6); the laboratory reports are included as Appendix D,the sample locations and analytical results are illustrated on Figure 2. Laboratory detection limits(DLs) listed in Table 3-1 and discussed below refer to the concentrations below which the analyses cannot detect a particular chemical compound. The DLs are determined by the analytical method,the degree of interference in the analysis by other compounds, or matrix effects, and are subject to the QA/QC test and protocol associated with certified laboratory analyses. ' Concentrations of chemicals of concern in the soil collected from beneath the ' pipeline at the Site have been evaluated according to the following published agency guidelines: ' • LUFT values(SWRCB, 1989), and • Preliminary Remediation Goals (PRGs) for industrial soil (EPA, 2004). ' LUFT values are guidelines for the protection of groundwater at leaking underground tank sites. Preliminary Remediation Goals(PRGs, 2004)published by the US Environmental Protection Agency (EPA) and California Environmental ' Protection Agency's (Cal EPA's)modified PRGs are estimates of chemical concentrations in soil, water, or air which, under standard exposure scenarios of either residential or industrial use, are used for an initial screening tool generally ' protective of human health, as an initial cleanup goal, or as a tool to determine the need for additional evaluation of health risk. ' • Soil sample 3-21"N, collected from 21 inches below the north end of the piping did not contain-any constituents of concern. • Soil sample 2-9"C, collected from 9 inches below the center of the piping ' contained minor concentrations of TPH-g and TPH-d. • The lab noted that the sample chromatographic pattern for TPH-d did not ' match the pattern of the specified sample pattern in any of the TPH-d analyses. 1 ' R:\2000_08\370_soil rpt_Mt vemon.doc 4 ' Fastri P,3501 Mt. Vernon Project#200370 tMay 2008 ' Sample 1-20"S Soil sample 1-20" S, collected from 20 inches below the south end of the piping contained significant concentrations of benzene, toluene, ethylbenzene, xylenes ' and TPH-g. • The concentration of benzene in the soil, 1,600 µg/Kg, exceeds the PRG for industrial soil of 1,400 pg/Kg, and the LUFT value of 1,000 µg/Kg (1 mg/Kg). • The concentrations of toluene, ethylbenzene, and xylenes exceed the LUFT ' values but do not exceed the PRG's. • The concentration of.TPH-g exceeds the LUFT value, no PRG value has been established for gasoline.

RA2000 08\370 lab results table.xlsSheetl ' Fastrip,3501 Mt.Vernon Project#200370 ' May 2008 ' 4.0 CONCLUSIONS AND RECOMMENDATIONS Conclusions: The key elements in evaluation of environmental risk for this project include the ' chemical concentrations, the presence of source material,the depth to groundwater, the reduction of potential for infiltration of surface water, and the location of the impacted soils relative to buildings. 1 Our conclusions are based on the elements noted above, and analytical results: ' • The concentrations of benzene in the soil exceed regulatory values below the north end of the piping. ' • The piping has been replaced and the impacted soils are below concrete which significantly reduces the potential for infiltration of rainwater or surface water that would carry chemicals of concern down to the groundwater. The concrete ' also reduces the potential for,volatile chemicals to diffuse into the air at the Site. • Groundwater below the impacted soils is at approximately 400 feet below ground ' surface. ' • The area of impacted soils is small and not located near the market building. • There is no mechanism to drive the gasoline within the impacted soils towards the ' groundwater. It is unlikely that the small area of impacted soils will leach chemicals of concern to the groundwater. It is also unlikely that any volatile organic compounds from the gasoline impacted soil are migrating into the on-site market building. ' Recommendations: RAM recommends that no further action be taken at the Site. It is our opinion that the recommendations are protective of the groundwater, current use of the Site based on its ' zoning, and biological receptors. 1 1 ' R:\2000_08\370_soil rpt_Mt vemon.doc 7 Fastrip,3501 Mt.

Subcontractors will certify their review by signing a HASP training record form or signing the field notebook after the tailgate safety ' meeting. The Project Manager is responsible for distributing this site safety plan to appropriate personnel and verifying review by obtaining signed review forms. Signed review forms will be placed in project files. Whenever a change of conditions on-site occurs that may affect safety, the Site Safety Officer or his/her designee will conduct a tailgate safety meeting if appropriate. Changing site conditions that may affect safety include the following: ' R:\2000_08\370_Hea{th&Safety Plan.DOC 4 • Change of field personnel (RAM or subcontractor), • change in work activity, • change in weather conditions; and, • visitors on site. ' All training sessions, safety meetings, and safety briefings will be documented by the Site Safety Officer or his designee in the field notebook. Documentation will include a brief description of topics addressed and the signatures of all training attendees. 5.0 HAZARD ASSESSMENT ' 5.1 PHYSICAL HAZARDS ' Working with soil sampling equipment 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, ' • exposure to noise generated by heavy machinery, ' • exposure to soil dust generated by heavy machinery, • insufficient or faulty protective equipment; and • insufficient or faulty operations, equipment, or tools, ' • vehicular traffic at and around the Site. ' RA2000_08\370_Health&Safety Plan.DOC 5 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 exposures; however, this section is ' included as a precautionary measure. Specific precautions will be taken as the situations at the site dictate. ' 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 by hand soil sampling activities. ' 5.3 EXPLOSION AND FIRE ' Explosive and Flammable products are not expected to be encountered at this site. ' 6.0 AIR MONITORING No organic vapors are expected at this site. There will be no air monitoring for organic vapors. Visual observations and monitoring shall be conducted for dust; dust inhalation ' will be avoided at all times. However, a photoionizing detector (PID) will be onsite for evaluation of potential organic vapors. 1 7.0 GENERAL PROJECT SAFETY REQUIREMENTS ' 7.1 GENERAL SAFETY PRECAUTIONS ' The project operations shall be conducted with the following minimum safety requirements employed: R:\2000-08\370—Health&Safety Plan.DOC 6 1 • Eating and drinking will be restricted to a designated area, • wearing loose clothing around operating machinery (Geoprobe) will be tprohibited, • all personnel shall be required to wash hands and face before eating or ' drinking, • all personnel shall avoid dust on-site by staying upwind of dust generated ' by sampling activities, ' gross decontamination and removal of all personal protective equipment (if necessary) shall be performed prior to exiting the facility, ' shaking or blowing of potentially contaminated clothing or equipment to remove dust or other materials is not permitted, ' the Site Safety Officer will be responsible to identify and alert field employees to physical hazards present at the site. 7.2 SYMPTOMS OF CHEMICAL EXPOSURE Chemical exposure is not anticipated. The information below is provided as a ' precautionary measure. Field operations personnel shall inform each other of non-visual symptoms that may ' indicate chemical exposure such as: ' 0 Headaches, • dizziness, • nausea, • blurred vision, ' 0 cramps, ' 0 coughing, R:\2000-08\370—Health&Safety PIan.DOC 7 • irritation of eyes, skin, or respiratory tract, ' 0 complexion changes in or skin discoloration g P ' 0 changes in apparent motor coordination, ' 0 changes in personality or demeanor, ' 0 excessive salivation or changes in papillary response;and • changes in speech ability or pattern. ' 7.3 HEAT STRESS The following recommendations will help to reduce heat stress: ' Provide plenty of liquids, • P tY 4 ' wearing of an undergarment that acts to help ventilation of the body, ' 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 rest 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 Xrocess should be continued until the body temperature does not exceed 99 F, • body water loss can be monitored using a scale to measure changes in body weight. ' RA2000 08070_Health&Safety Plan.DOC 8 8.0 ' PROTECTIVE EQUIPMENT REQUIREMENTS ' Field personnel and visitors are required to wear hard hats, safety glasses, steel-toed boots, and hearing protection (at the discretion of the Site Safety Officer) in the ' operations area when work is being performed.

(RAM) is pleased to present this Site Investigation Workplan'for the JACO OIL owned Fastrip (# 773) self-serve gas station and convenience store. This gas station is located at 3501 Mt. Vernon Avenue, ' Bakersfield, California (Site), (see Figure 1 for an Area Map and Figure 2 for a Plot Plan of the Site). 1 A letter from the Bakersfield Fire Department Office of Environmental Services(BFD) dated June 17, 2008 requested a work plan for further definition of a plume below one end of the former piping that had been replaced (see Appendix A for copies of regulatory ' correspondence). Soil samples were collected from beneath piping that was being replaced on May 6,2008, ' analytical results of these samples showed'that soil 20 inches below the south end of the piping was impacted with hydrocarbons. A report summarizing the soil sampling and analytical results was submitted to the Bakersfield Fire Department(BFD), Prevention Services Division for review. .Based on their review, the BFD issued a letter on June 17, 2008 (see Attachment A—BFD Correspondence), which requested a workplan for ' further investigation of soils beneath the pipe. RAM proposes to advance two borings at the site, using a Hollow-stem auger, to evaluate the vertical and horizontal extent of the petroleum impacted soils. Soil samples will be collected at 5-foot intervals..Selected soil samples will be analyzed by a California state certified laboratory for Total Petroleum Hydrocarbons as gasoline (TPHg); Benzene, ' Toluene, Ethylbenzene, and Xylenes (BTEX); and fuel oxygenates. This Site Investigation Workplan follows the guidelines presented in ' Appendix A Reports, Tri-Regional 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.

Project#200370 Site Investigation Workplan ' July 2008 1.2 Site History On May 6, 2008 RAM Environmental Engineering Services,Inc. (RAM) conducted soil sampling at the Fastrip market and gas station located at 3501 Mt. Vernon, Bakersfield, California'(Site), as noted in Figure 1,Area Map. Soil ' samples were taken from beneath piping that was being replaced. The sampling was conducted to assess the potential presence of petroleum hydrocarbons in soils beneath former piping at the station as the equipment was modified under Bakersfield Fire Department(BFD)Permit to Modify Underground Storage Facility,permit number MD0407. ' An excavation was developed to expose and replace piping leading from the USTs to the dispenser islands, as shown on Figure 2,Proposed Borings. The underlying soils were sands,clays and gravels. Soil samples were taken under the ' direction of BFD from below the former piping at the ends and'in the center of the piping run. The soil samples were collected from between 9.inches and 20 inches below the excavation. It_was not possible to obtain deeper samples due to the ' gravel in the soil. A summary of soil sample analytical results is presented in Table 1 following the text, and on Figure 2,Proposed Borings. Complete analytical reports are included in Attachment B. ' In the soil sample collected from below the south end of the piping, hydrocarbons ' were detected as follows. Sample 1-20"S Soil sample 1-20" S; collected from 20 inches below the south end of the piping contained significant concentrations.of benzene, toluene, ethylbenzene, xylenes and TPH-g. The key points of this sample's analytical results are: r • the concentration of benzene in the soil, 1,600 µg/Kg, exceeds the PRG for industrial soil of 1,400 µg/Kg, and the LUFT value of 1,000 µg/Kg (l ' mg/Kg), • the concentrations of toluene,ethylbenzene, and xylenes exceed the LUFT values but do not exceed the PRG's,'and • the concentration of TPH-g exceeds the LUFT value. No PRG value has been established for gasoline. 1 R:\2000_08\370_SI_workplan_3501 Mt.Vemon Ave.doc 3 3501 Mt.Vernon Avenue,Bakersfield RAM Environmental Engineering,Inc. Project#200370 Site Investigation Workplan ' July 2008 2.0 INVESTIGATION PURPOSE AND SCOPE The objective of the proposed Site Investigation is to: • define.the vertical and horizontal extent of hydrocarbon impacted soils within the proximity of the known pipe Jeak; • obtain certified analytical data on hydrocarbon concentrations in soil samples; 1 • if groundwater is encountered, collect grab samples for analysis of potential impacts from the fuel leak; ' • evaluate the Site Investigation results to determine if further investigation or remediation'is necessary; and • present the findings of the Site Investigation and recommendations to the BFD. To meet these objectives;the Site Investigation will include the following tasks: • obtain BFD approval of this Workplan and attached Health and Safety Plan ' (Attachment C); • sample soils at five-foot intervals from two borings drilled with a hollow-stem auger to evaluate the extent of hydrocarbon containing soils at the Site; ' • record soil characteristics and field PID measurements in field boring logs; • analyze selected soil samples for TPH-g, BTEX; and fuel oxygenates; • evaluate findings of the investigation; and • report Site Investigation results, evaluations, and recommendations for further action to BFD. ' 3.0 SITE DESCRIPTION 3.1 Site Description Currently, the Jaco Owned Fastrip mini-market and self-serve gas station operate on the Site. The gas station distributes gasoline from 2 dispenser islands with 2 dispensers per island and;3 underground storage tanks(USTs), consisting of one 12,000-gallon regular unleaded gasoline, one 12,000-gallon premium gasoline, and one 12,000-gallon diesel UST. The service station is located on the northwest corner of the intersection of Mt. Vernon Avenue and University Avenue in Bakersfield, California. Adjacent to the service station to the south is a residential area, and to the north east and west are parking areas associated with the adjacent ' Bakersfield College. 4.0 TOPOGRAPHY,GEOLOGY AND HYDROGEOLOGY 4.1 Topography The Site is at an elevation of approximately 700-feet above sea level. The ' topography slopes moderately to the southwest (see Figure 1—Area Map). 1 ' RA2000_08\370_S1_Workp1an_3501 Mt.Vemon Ave.doc 4 ' 3501 Mt.Vernon Avenue Bakersfield RAM Environmental Engineering,Inc. , Project#200370 Site Investigation Workplan July 2008 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 outcrop along most of the eastern and southeastern flanks of the Great Valley, while marine rocks of pre- ' Tertiary age outcrop 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 uppermost sedimentary units in ' the vicinity of the Site are Quaternary, Recent fan deposits. 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 located approximately 4,700 feet to the northwest. ' 4.3 Hydrogeology There are no surface waters in the immediate Site area. The regional unconfined groundwater at the Site is at approximately 480 feet below ground service (bgs); ' the groundwater flows to the north (KCWA 2004). 4.4 Past leak, 1994 A survey of Leaky Underground Fuel Tank(LUFT) sites in the area on the California State Water Resources web site "GeoTracker" shows that a leak was discovered at the Site in 1994. According to Mr. Craig Perkins of the BFD,the leak was a"non-petroleum spill". The case was closed in 1995. 4.5 Public drinking water wells The Kern County Water Agency map of Water Wells and Spreading Areas (April 2004, Plate 3) shows no water wells in the Site vicinity. 1 ' RA2000_08\370_Sl_Workplan_3501 Mt.Vernon Ave.doc 5 ' 3501 Mt.Vernon Avenue,Bakersfield RAM Environmental Engineering, Inc. Project#200370 Site Investigation Workplan ' July 2008 ' 5.0 QUANTITY.OF CONTAMINANT RELEASED The quantity of contaminant released is unknown. 6.0 STRATEGY AND'PROCEDURES FOR SITE INVESTIGATION The goal of this site investigation will be to develop one boring as close as possible to the impacted soils below the piping, and a second boring to the south of the first boring. As ' the leak from the piping is located above the underground tanks, it will not be possible to develop a boring in the same location of the preliminary soil samples. ' Soil samples will be collected at five foot intervals progressing vertically below any hydrocarbon impacted soil encountered until two consecutive soil samples have been collected that show no signs of hydrocarbon impacts. Prior to any intrusive methods being conducted at the Site, USA of Northern California will be utilized to map out-the underground utilities at the Site. Based on the clearances ' obtained, RAM will site the soil borings in safe locations. 6.1 Sample Collection ' To assess the vertical.extent and horizontal extent of impacted soil RAM will advance two (2) soil borings (borings B-1 through B-2) with a hollow-stem auger. The borings will be hand augered to a depth of 5 feet before advancing the ' hollow-stem auger. Boring B-1 will be located as close as possible to the known hydrocarbon impacted soil (see Figure 2—Proposed Borings). All borings will ' be deepened to 10 feet below the lowest field detectable volatile organic compounds(VOCs)and/or visible staining, or to the depth of the groundwater, if encountered, or until drilling refusal is encountered. A PID model Photovac ' 2020, 10.6 eV UV lamp will be used to test for the presence of VOCs. Soil samples will be collected at 5 foot intervals, beginning at 5 feet below ground I surface (bgs), the soil samples 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 generated. Soils will be described and classified according to the Unified ' Soils Classification System (USCS); observations of soil staining or discoloration will be included on the lithologic log. Soil sampling will proceed according to the soil sampling plan (Attachment D). Groundwater is not expected to be ' encountered. 1 1 R:\2000_08\370_SI_workplan_3501 Mt.Vernon Ave.doc 6 ' 3501 Mt.Vernon Avenue Bakersfield RAM Environmental En Engineering,g g, Inc. . Project#200370 Site Investigation Workplan ' July 2008 ' 6.2 Analytical Methods Soil samples will be handled according to RAM's Soil Sampling Plan, which is included in Attachment D. The samples will be labeled, stored in an ice cooler 1 cooled with blue ice and then transported to CalScience Laboratory at the end of the working day. The soils-.will be analyzed as follows: ' • Total petroleum hydrocarbons as gasoline (TPH-g, carbon range C 6- C 10) by EPA Method 8015M, ' • Total petroleum hydrocarbons as diesel (TPH-d, carbon range C 10- C 28) by EPA Method 8015M, ' Benzene, Toluene, Ethyl-benzene and Xylene (BTEX) by EPA Method 8260B, and • Oxygenates, t-Butanol (TBA)Tert-Buryl Alcohol, Methyl Tert-Butyl Ether(MTBE), Diisopropyl Ether(DIPE), Ethyl Tert-Butyl Ether(ETBE), Tert-Amyl Methyl Ether(TAME);by EPA Method 8260B. 1 6.3 Boring Closure ' When the total depth of the boring is reached, as determined in the field from observations, bentonite pellets will be placed in the boring and hydrated. The surface will be compacted and covered with cement or asphalt to match existing ' grade. .6.4 Work Schedule The Site Investigation will begin within 45 days after the workplan has been accepted by BFD, and after all permits are obtained. Jaco prefers to schedule the work at the same time as the work to be conducted at the Howard's mini-mart on Planz Road. BFD will be notified approximately 48 hours before fieldwork commences. A Site Investigation Report will be submitted to BFD approximately 45 days after completion of the Site Investigation and receipt of analytical data. 7.0 WASTE MANAGEMENT Drill cuttings (soil) generated by drilling soil borings will be placed in labeled.drums and left on-site. The drum contents will be properly disposed of after soils laboratory analyses have been received, and the waste has-been profiled. ' R:\2000_08\370_SI_Workplan}501 Mt.Vemon Ave.doc 7 3501 Mt.

The Project Manager is responsible for the provisions and submittal of this plan, and for advising the Site Safety Officer on health and safety matters. The Project Manager has ' the authority to provide for the auditing of compliance with the provisions of this plan, suspension or modification of work practices, and administration of disciplinary actions for individuals whose conduct does not meet the requirements set forth herein. The ' Project Manager may elect to give the Site Safety Officer authority to administer disciplinary actions for individuals. whose conduct does not meet the requirements set ' forth herein. The Site Safety Officer is responsible for the dissemination of the information contained ' in this plan to all REBRAC personnel assigned to the project, and to the responsible representative of each subcontractor firm working under REBRAC on the project. As such, he or she is responsible for performing or providing the following as necessary: • Adequate on-site safety supplies & equipment inventory (see list of ' protective equipment, Sec. 8.0), for RAM personnel. Compliance for having necessary Safety Supplies and Equipment rests solely with each subcontractor, • tailgate discussion of Site Safety Plan; documentation of tailgate safety ' meetings in field notebook, • documentation of all accidents or safety plan violations, ' emergency contacts as needed, ' implementation of Decontamination/Contamination Reduction Procedures (see Sec. 9.0), • on-site air monitoring as required (see Section 6.0). ' R:\2000_08\370_H&S Plan_SI workplan.doc 12 The Site Safety Officer or his/her designee has the authority to suspend work any time he ' or she determines that the health and safety practices at the site are inadequate and shall also inform the Project Manager of individuals whose conduct is not consistent with the requirements of the plan. 3.0 MEDICAL SURVEILLANCE RAM personnel and sub-contractors engaged in project operations that may expose them ' to hazardous wastes, hazardous substances, or any combination of hazardous wastes or hazardous substances shall be participants in a Medical Surveillance program, and must be cleared by the examining physician(s) to wear respiratory protection devices and 1 protective clothing for working with hazardous materials. The applicable requirements under the CAL OSHA standard for Hazardous Waste Operations and Emergency Response (Title 8 CCR, GISO S 192) will be observed where potential hazardous wastes are encountered. ' 4.0 SAFETY/ORIENTATION TRAINING ' Field personnel from RAM and any subcontractors will review this site-specific Health and Safety Plan (HASP) before beginning.work as safety training for this project. The Site Safety Officer will conduct a tailgate safety meeting to review the HASP prior to the ' start of field operations. RAM project personnel will certify their review by signing a HASP training record form (Appendix B). Subcontractors will certify their review by signing a HASP training record form or signing the field notebook after the tailgate safety ' meeting. The Project Manager is responsible for distributing this site safety plan to appropriate personnel and verifying review by obtaining signed review forms. Signed review forms wil,l be placed in project files. Whenever-a change of conditions on-site occurs that may affect safety, the Site Safety Officer or his/her designee will conduct a tailgate safety meeting if appropriate. Changing site conditions that may affect safety include the following: 1 1 ' R:\2000_08\370_H&S Plan_SI workplan.doc 12 1 , • Change of field personnel (RAM or subcontractor), • change in work activity, • change in weather conditions; and, ' visitors on site. ' All training sessions, safety meetings, and safety briefings will be documented by the Site Safety Officer or his designee in the field notebook. Documentation will include a brief description of topics addressed and the signatures of all training attendees. ' 5.0 HAZARD ASSESSMENT ' 5.1 PHYSICAL HAZARDs Working with drilling equipment 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, ' • exposure to noise generated by heavy machinery, ' • exposure to soil dust generated by heavy machinery, • insufficient or faulty protective equipment; and • insufficient or faulty operations, equipment, or tools, • vehicular traffic at and around the Site. 1 ' RA2000 08\370_H&S Plan_SI workplan.doc 12 1 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 exposures; however, this section is included as a precautionary measure. It is most likely that the hazard at this site will be from refined products found during the sampling of the soil. Specific precautions will be ' taken as the situations at each of the sites dictate. Following is a discussion of the chemical hazards of petroleum hydrocarbons. 1 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, BTEX 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 BTEX (Appendix ' Q. 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 and 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 which present potential inhalation ' exposures as described in Section 6.0. R:\2000_08\370_H&S Plan_SI workplan.doc 12 ' 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 drilling activities. 5.3 EXPLOSION AND FIRE ' The types of hydrocarbons expected to be present 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 ' RA2000_08\370_H&S Plan_SI workplan.doc 12 ' Table 1.

' b STEL: Short term e exposure limit is the employee's 15-minute time weighted average p g g ' airborne exposure which shall not be exceeded at any time during a work day. ' 6.0 AIR MONITORING An organic vapor analyzer (OVA) with a flame-ionization detector (FID) or Hnu . ' photoionization detector (PID) will be used to conduct air monitoring during activities where potential for airborne exposure exist, specifically during soil sampling. During soil sampling, 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 ' R:\2000_08\370_H&S Plan_SI workplan.doc 12 ' 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 P g 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.

' R:\2000_08\370_H&S Plan_SI workplan.doc 12 ' 7.0 GENERAL PROJECT SAFETY REQUIREMENTS ' 7.1 GENERAL SAFETY PRECAUTIONS The project operations shall be conducted with the following minimum safety requirements employed: • Eating and drinking will be restricted to a designated area, • wearing loose clothing around operating machinery (Geoprobe) will be ' prohibited, ' 0 all personnel shall be required to wash hands and face before eating or drinking, ' 0 all personnel''shall avoid dust on-site by staying upwind of dust generated by sampling activities, ' 0 gross decontamination and removal of all personal protective equipment (if necessary) shall be performed prior to exiting the facility, ' 0 shaking or blowing of potentially contaminated clothing or equipment to remove dust or other materials is not permitted, • the Site Safety Officer will be responsible to identify and alert field ' employees to physical hazards present at the site. ' 7.2 SYMPTOMS OF CHEMICAL EXPOSURE ' Chemical exposure is not anticipated. The information below is provided as a precautionary measure. ' Field operations personnel shall inform each other of non-visual symptoms that may indicate chemical exposure such as: • Headaches, ' dizziness, RA2000_08070_H&S Plan_SI workplan.doc 12 0 nausea, blurred vision, ' 0 cramps, ' 0 coughing, irritation of eyes, skin, or respiratory tract, changes in complexion or skin discoloration, 1 changes in apparent motor coordination, changes in personality or demeanor, excessive salivation or changes in papillary response; and ' 0 changes in speech ability or pattern. ' 73 HEAT STRESS ' The following recommendations will help to reduce heat stress: • Provide plenty of liquids, 1 • wearing of an undergarment that acts to help ventilation of the body, 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%, RA2000_08\370_H&S Plan_SI workplan.doc 12 1 1 • body temperature can be used to screen for heat stress. If the oral ' temperature at the beginning of the rest 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 Xrocess ' should be continued until the body temperature does not exceed 99 F, ' body water loss can be monitored using a scale to measure changes in body weight. 1 8.0 ' PROTECTIVE EQUIPMENT REQUIREMENTS ' Field personnel and visitors are required to wear hard hats, safety glasses, steel-toed boots, and hearing protection (at the discretion of the Site Safety Officer) in the operations area when work is being performed. Field personnel engaged in work operations are required to wear the following additional ' equipment if unknown chemicals of concern are encountered: ' 0 Long-sleeved shirts and pants or one-piece coverall, such as Tyvek disposable, ' poly-coated Tyvek suit (when contact with potentially contaminated material is anticipated), ' rubber boots (when contact with potentially contaminated soil or liquid is anticipated), • orange safety vests, ' all personnel shall be required to wash hands and face before eating or drinking, 1 ' R:\2000_08\370_H&S Plan_SI workplan.doc 12 • p er Bonn el are not required to wear protective dust masks. Therefore, personnel shall be required to avoid breathing dust on site at all times, and work upwind. ' Contractors to RAM will provide their own PPE. 8.1 OPERATIONS AREA Dermal contact will be the potential exposure pathway of concern for chemical exposure. Inhalation exposure will only be a significant concern when dusty conditions or organic vapors are present. Protective clothing, including Tyvek suits, rubber boots, and chemically resistant gloves ' such as nitrite, will be mandatory for all field operations personnel when contacting potentially contaminated soils. When the ambient air monitoring level equals or exceeds 5 ppm, full or half-face APR's with organic vapor cartridges will be required. Personnel ' should approach any unknown substances from upwind. ' 9.0 DECONTAMINATION/CONTAMINATION REDUCTION PROCEDURES Chemical exposure is not anticipated at this Site. This section is included so that procedures are established in the event that unknown chemicals are present at the Site. t Boots, clothing, gloves, and other equipment can become contaminated by direct exposure to contaminated soil or groundwater. Precautions will be taken to prevent the transport of contaminants off site unless in an approved container or other approved method. All contaminated personal protective equipment or clothing will be decontaminated on-site, or placed in appropriate storage or disposal receptacles. ' R:\200008\370H&S Plan_SI workplan.doc 12 10.0 ' EMERGENCY RESPONSE PROCEDURES ' A first aid kit will be taken into the field each day. In the event of a fire, explosion, physical 'injury or illness due to chemical exposure, the appropriate parties should be ' contacted using the below listed phone numbers. For injuries or illness other than very minor cuts or scrapes, a physician's attention,is requited.

Vernon*Avenue, Bakersfield, California. RAM Project#200370 Task I — Soil Sampling ' TASK OBJECTIVE: Sample soils at 5 foot intervals in a boring developed at the site investigation for the above referenced site, as required by the City of Bakersfield Fire Department, for analysis of TPH-d, TPH-g, BTEX and fuel oxygenates on a standard turn around time basis. SOIL SAMPLE ANALYSIS: Laboratory analysis will be conducted by an environmental testing laboratory certified by ' the State of California for the tests to be performed. Test methods and criteria are as follows: ' • TPHg and TPHd Modified EPA Method 8015M • BTEX, and fuel oxygenates EPA Method 8260B • Analytical Laboratory—Calscience, Garden Grove, CA • Standard sample turnaround time—5 day results. • Report results to RAM Environmental Engineering Services, Inc. ' SOIL SAMPLING PROTOCOL Soil sampling will be conducted in accordance with RAM Environmental Engineering Services Standard Soil and Groundwater Sampling Protocols (RAM, 2003) and will incorporate the following project specific criteria. Sampling Locations ' Samples will be collected at 5 foot intervals beginning from 5 feet below grade. Soil samples will be collected with a hollow-stem auger drilling rig and a California modified split-spoon sampler. ' Soil Confirmation Information Sample at 5-foot intervals within the boring- • Use the hollow-stem auger and a split-spoon sampler to obtain samples, • use Teflon seal and plastic caps to seal metal sleeve from the sampler, • monitor soils and void space with hand held PID or equivalent. Equipment: ' • Split-spoon sampler, • Brass Sleeves (or.equivalent), • teflon tape and plastic caps, ' • disposable gloves, baggies,permanent marking pens, sample labels, chain of custody (COC)forms, Field Log forms, • PID, Model Photo Vac meter for monitoring work space for volatiles, • Personal Protective Gear per Standard Health and Safety Protocols for fuel impacted soils, • pre-chilled non-water cooling material (Blue Ice) for sample storage/shipping container. RA2000_08\370_sampling plan_SI workplan.doc 1 Sampling Procedure ' A split-spoon sampler will be hammered into the soil at five foot intervals. The lowermost sample will be used for lithologic descriptions and to measure the presence/absence of volatile organic compounds. The emissions from the soil will be ' monitored with a vapor monitor and the results recorded. The middle metal sleeve will be properly sealed with Teflon tape, followed by a plastic cap. The metal sleeve will be labeled as described below. Excess soil will be placed in labeled barrels pending waste characterization for management. ' Sample Identification and Labeling Complete sample label information and sample COC information prior to collection of each sample, leaving time for notation dust after collection. ' The sample should be labeled as follows; ' boring number, • collection depth, • collection time (using military time), ' collection date, • responsible party, and • RAM Job Number 200370. Label the metal tube,place the metal tube in a zip lock bag, and place the bagged sample in sample shipping container(ice chest). Fill other containers, and label and store in the ' same manner. ' Check/complete the COC form and sample logs, and secure the sample storage/shipping container until delivered to the laboratory. Sample container should be kept at V C with blue ice. 1 1 RA2000_08\370_sampling plan_SI workplan.doc 2 t LH UU MAI XIAL�),� " •�.
