(AGI)to prepare this Addendum to the Remedial Action Plan, originally - submitted by RESNA in February, 1992, for Soil Remediation at the Former Aut° Club of Southern C~lifornia located at 2301 "F" Street, Bakersfield, Kern County, California (Exhibit 1). -- 2.0 PROJECT PURPOSE 'The addendum to the Remedial Action Plan describes the methods to be used by - AG! in order t° accomplish, remediation of gasoline impacted soil at the Former Auto Club of-Southern California located in Bakersfield, California. The Addendum to the Remedial Action Plan has the follOwing objectives: .~ · Outline the soil remediation plans. This outline represents AGI's -' initial assessment of the contamination problem at the Auto Club site, ~ and the time frame for the implementation of the different phases of remediation; ' Construct a site location map showing all structures, vapor extraction wells, and property 'boundaries; · Obtain the necessary permits as required for the VES construction, installation, trenching, and manifolding; · Operate, monitor, and maintain the Vapor Extraction System for the duration of effective remediation; · Advance confirmatory soil borings to confirm satisfactory site remediation; · Prepare a closure report summarizing methods and results of the soil remediation program; and · Decommission remediation equipment and properly abandon all vapor extraction wells upon approval of site closure by City of Bakersfield 'Fire Department. 3.0 PROJECT SCHEDULE AquaGeosciences, Inc. anticipates beginning work described in this Addendum to the Remedial Action Plan (Task 1) within one week upon approval from the City of Bakersfield Hazardous Materials Division (City), the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD), and the Automobile Club of Southern California .(Client). Task 2 - Vapor Extraction Well manifolding will take approximately one (1) week to complete following the Addendum to the Remedial Action Plan approval and right of entry agreements with the owners. 'Task 3 - Installation and operation of the vapor extraction surface equipment will require approximately two (2) weeks and will be done concurrent with Task 2. Start- up of the unit will depend upon the time frame involved in obtaining an authority to construct (ATC) permit from the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD) and following that, a permit to operate (PTO) for sustained equipment operation. Should a source test be required for this unit prior to permitting, another two (2) weeks may be added to the schedule. Vapor extraction remediation (operations and maintenance) is expected to require twelve (12) months. Task 4 - Confirmatory borings will be accomplished within one (1) week of the decision to test for closure. Analytical data can be received in a normal two (2) week turnaround. Task 5 - The final Closure Report will be generated within four (4) weeks of receipt of the confirmatory soil boring analytical data. Task 6 - Equipment Decommissioning and Abandonment will require approximately four (4) weeks after closure'approval from the City of Bakersfield Fire Department - Hazardous Materials Division. Overall, the project duration is expected to be eighteen (18) months. 4.0 BACKGROUND The site is located at 2301 "F" Street in Bakersfield, California as shown on Exhibit 1. 4.1 FACILITY DESCRIPTION The property is currentlY occupied by Easton & Moran Orthopedic & Sports Physical Therapy. (Exhibit 2). 4.2 PROJECT HISTORY In 1991,.RESNA. was contracted to perform a Phase I Real Estate Site Assessment at the former Auto Club of Southern California site located at 2301 "F" Street, Bakersfield, California. RESNA indicated that a gasoline service station was previously operated in the northeast portion of the subject property. According to information obtained 'from the City of Bakersfield Building Department, the station -- :- was 'apparently demolished in 1977 and records were not 'available regarding - Underground tank removal, or abandonment. On October 21, 1991, Spectrum Environmental Geophysics conducted a geophysical survey at the subject site to evaluate for underground tanks. Two (2) magnetic anomalies were. detected; however, the ground penetrating radar signatures of the anomalies did not indicate the presence of underground storage tanks. On NoVember 14, 1991 RESNA conducted a Phase II investigation which consisted of advancing three (3) soil borings to evaluate possible hydrocarbon contamination. Soil borings B-1 and B-2 were advanced to 20 feet and B-3 was advanced to 40 feet. Six (6) soil samples were submitted and analyzed for Total Petroleum hydrocarbons as gasoline (TPHg), BTEX, and Total Recoverable Petroleum Hydrocarbons (TRPH). The analytical results indicated non-detect to low concentrations of hydrocarbons in the samples collected from soil borings B-2 and B-3. The .highest concentrations were detected in boring B-l, which was subsequently (November 22, 1991) deepened to 45 feet. The analytical results from soil boring sample B-1 at 40 feet indicated a TPHg concentration of 2100 mg/kg. Based on the analytical results, the City of' Bakersfield Fire Department, Hazardous Materials Division (BFDHMD) was notified. The BFDHMD sent a letter, dated December 2, 1991 to the Auto Club of Southern California requesting that a site assessment be conducted in accordance with the Re~onal Water Quality Control Board (RWQCB) guidelines for evaluation of contaminant migration in the subsurface soils at the subject site. · -On FebruarY 3 and 4, 1992, RESNA advanced five (5) additional soil borings. Soil boring B-4 was advanced 5 feet west of soil boring B-1 to determine the vertical extent of hydrocarbon contamination. Due to auger refusal at 72 feet, two (2) consecutive non-detected soil samples were not obtained. Soil borings B-5, B-7, and B-8 were advanced to a depth ~of 30 feet each and B-6 was advanced to 35 feet, all to evaluate the lateral extent of contamination. Eighi'(8) soil samples were submitted and analyzed for TPHg and BTEX. The analytical results indicated that the highest concentrations were detected in the 60 foot sample of soil boring B-4. The concentrations detected in the 72 foot sample .indicated rapid attenuation and the vertical limits of the plume had been estimated to be approximately 80 feet. RESNA, in their report dated February 24, 1992, " 5 of 20 ~ presented an interpretation of the vertical and lateral extent of the gasoline impacted soil plume. Their interpretation indicated the plume had migrated to a depth of aPproximately twenty (20) feet. The volume of impacted soil is estimated to be 2,250 cubic yards containing an estimated 8,000 pounds of gasoline hydrocarbons. On August 5 and 17, 1992, RESNA advanced a total of fiVe (5) vapor extraction wells. Two (2) of the wells are located in the center of the plume and are screened in separate zones (shallow 15-45' and deep 50-70'). These wells are to be used as the primary extraction wells. The remaining three (3) wells are located around the perimeter of the plume and are screened from 15-55', 20-60', and 20-60', respectively. These wells are to be used as inlet wells. On September 10, 1992, RESNA set up a portable Granular Activated Carbon Vapor Extraction System on the site. The system was run for a period of two (2) hours under a SJVUAPCD permit exemption. Based on the data generated from this vapor extraction feasibility study, it appears that the current well configuration will be sufficient to effectively remediate the entire impacted soil mass. Based on RESNA's findings, the presence of gasoline hydrocarbons in soils at the site are in excess of the California Regional Water Quality Control Board - Central Valley Region Leaking Underground Fuel Tank leaching potential guidelines. RESNA felt remedial action would be required by the interested regulatory agencies. In-situ vapor extraction was recommended as the most effective and cost competitive option available to cleanup the site. AGI reviewed the Site Assessment Report and Remedial Action Plan, dated February 24, 1992 and a Vapor Extraction Pilot Test Report dated October 8, 1992, prepared by RESNA Industries. After reviewing the results and conclusions of the vapor extraction feasibility study, AGI believes the .soil vapor effluent data appeared to .be somewhat contradictory, therefore; in our proposal to the Automobile Club of southern California, AGI recommended that a electrically-heated catalytic oxidizer b~Used for on-site remediation. AGI's proposal was accepted by the Auto Club of S~uthern California in December, 1994. This proposal has since been revised to a!~ow for using an electrically heated Thermal Oxidizer in addition to the catalytic unit. 5.0 wORst,AN AquaGeosciences, Inc. plans to install an electrically-heated catalytic and/or thermal oxidizer sYstem at this site. As currently envisioned, the remediation will begin with the electrical catalytic unit. After approximately three (3) months, the electrical tl~ermal oxidizer (heated sand bed) will replace the catalyst and complete the remediation. Using 'the existing vapor extraction/inlet wells, AquaGeosciences, Inc. Will manifOld these wells to the Vapor extraction system. The effectiveness of the remediation will be confirmed by advancing soil borings through the contaminant plume region. '6.0 OUTLINE OF REMEDIATION PLANS The following scope of work is proposed by AG! in order to accomplish the timely and 'cost-effective remediation of gasoline impacted soil at the Former Auto Club of Southern California in Bakersfield, California. An outline is presented below and is folloWed bydetailed descriptions for each phase of work. Task 1 - Regulatory Liaison, Addendum to the Remedial Action Plan and Authority to Construct/Permit to Operate; Task 2- Vapor Extraction Wells and System Manifolding; Task 3 - Installation, Operation, and Maintenance of Vapor Extraction Remediation Unit; Task 4- Confirmatory Borings; Task 5- Final Report-; Task 6- Equipment Decommissioning and Well Abandonment. · -:- . Task 1 -~egulatory Liaison, Addendum to the Remedial Action Plan, and Authority to Construct AGI will obtain the permits and approval necessary from the appropriate regulatory agencies such as, but not limited to, the City of Bakersfield Fire Department Hazardous Materials Division (BFDHMD) and the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD). These permits include, but may not be limited to the Authority-to-Construct and Permit-to-Operate from the San Joaquin Valley Unified Air Pollution Control District. Please Note: AG! will apply for two (2) seParate ATC's. One for the electrical catalyst machine, and one for the electrical thermal oxidizer (heated sand bed). Permits required by local building ordinances or other codes for utility hook-ups will be obtained by the Client. AGI will prepare and submit this Addendum to the Remedial Action Plan (RAP), previously submitted by RESNA, to the BFDHMD for approval.. This Addendum to the RAP will set forth the treatment methods, equipment and schedule by which site closure is expected to be achieved. AquaGeosciences, Inc., Prior to implementation of any field operations, will investigate the site for existing utilities and will coordinate with the City to determine the best location for the trenches and manifold headers. All appropriate -utility shut-off valves or switches will be marked and copied for distribution to the on-site project team. If utility line locations are unclear, a professional line locator will be called prior to field operations commencing. Task 2 - Vapor Extraction Wells and System Manifolding Five (5) extraction/inlet wells, previously installed by RESNA, will be exposed by removing the existing well monuments. Two (2) of the wells located in the center of the plume, which will be used as the primary extraction wells, were previously screened in separate zones (shallow 15-45' and deep 50-70'). The remaining three (3) wells which are located around the perimeter of the plume and will be used as the inlet wells, were previously screened from 15-55', 20-60', and 20-60', respectively. A sawcutter will be employed to saw-cut the asphalt leading from the equipment compound to each well. The asphalt will be removed and approximately eighteen (18) inch deep by twenty-four (24) inch wide trenches will be excavated with a backhoe. SPoils will be stockpiled adjacent to the trenches for eventual use as backfill.material. Two (2) inch diameter Schedule 40 PVC pipe and fittings will be used to convey extracted vapors from the extraction wells and/or allow ambient air to the inlet wells. All plumbing lines will be manifolded to an extraction header that will be located within the equipment compound. The extraction header will be constructed using Schedule 80 four (4) inch PVC, (2) flow meters, (5) PVC ball valves, and assorted couplings and fittings. This header is later connected to the VES. All trenches will be baCkfilled and compacted to specification. Class II base and asphalt will be used to return the site to its original condition. Additionally, a chain link fence will be installed that is equipped with slats to allow for noise abatement and reduce visual interest. The fence will have a locking gate. Exhibit 2 shows the locations of the vapor extraction/inlet wells as well as the location of the vapor extraction unit. A minimum of space will be used to secure the VES and the extraction header. Exhibit' 3 details AGI's proposed trench, manifold and vapor extraction/inlet well locations. The exact locations may need to'be field revised depending upon underground and/or overhead utility locations. Task.-3 - Installation, Lease, OperatiOn, and Maintenance of Vapor Extraction - :' Remediation Unit A 200 CFM blower/electrical catalytic oxidizer unit will be installed immediately after the manifolding of the vapor extraction wells is completed. The proposed vapor remediation unit will use electric heating primarily ~and also a catalytic module to destroy the hydrocarbon vapors extracted from the soil. The unit has a 99% destruction efficiency. This unit is equipped with a complete safety shutdown system which prevents unauthorized startup should the machine sense a problem and shutdown. It continually monitors LEL, pressure, temperature, and flow. It also separates water from the vapor stream and will automatically pump the water to 55-gallon drums. EqUipment specifications are provided as Appendix B. After approximately three (3) months of operation, the electrical Catalyst unit will be replaced with an electrically heated, silicon sand bed thermal oxidizer. The thermal oxidizer is capable of handling a 250 CFM flow and is also rated at 99% destruction efficiency. The unit is equipped with a continuous strip chart recorder, which records flow, temperature, and % of LEL. The unit is PLC controlled and is equipped with remote telemetry for remote monitoring. Equipment specifications are included as Appendix C. The operations and maintenance of the system is to inclUde all materials and supplies necessary to conduct normal operational activities such as field screening, systems-checks, and adjustments, and regular lubrication and maintenance. Task 4 - Confirmatory Borings At such time 'that vaPor extraction, in conjunction with field screening records indicate that the remedial goals have probably been met, AG! will advance two (2) confirmatory soil borings within the center of the plume to confirm that site remediation has been accomplished. The soil borings will be advanced using a CME-75 hollow stem auger drilling rig, or equivalent, in accordance with established drilling and sampling protocols. Soil samples will be collected at five (5) foot intervals in brass sample sleeves, and sealed, stored, recorded on Chain-of-Custody' documents, and transported in a chilled cooler at 4° centigrade for analysis at a State Certified laboratory.. Task 5 - Final Report Following satisfactory completion of the remediation project (generally two consecutive quarters of trace to non-detect TPHg in vapor effluent samples and concentrations in the confirmation soils samples at or below the remedial target concentrations). Note: Remedial target concentrations will-be 100 ppm for TPH as .gas in _soil and non-detected for the volatile aromatics (BTEX). AGI will prepare a final "Closure Report". Thee Closure Report will summarize the project history, the remedial actions undertaken, field activities and treatment equipment, laboratory analytical data, confirmation sampling results, and closure criteria for the site. Based upon the project data, the repOrt will conclude with a recommendation for ..... site closure. The Final Report will be certified by a State of California Registered Geologist. Task 6 - Equipment Decommissioning and Well Abandonment Upon confirmation that the remediation has met the required closure criteria, AG! will remove and/or abandon in place all man-made conduits, lines, wells, and manifolds assodated with the project. The equipment used on site will be disconnected, prepared for shipping, and finally transported from the site to the appropriate destinations. 7.0 METHODS The following sections describe in detail the methods to be employed in implementing this Addendum to the Remedial Action Plan. 7.1 Drilling Methods The confirmation soil borings will be advanced using a CME-75 Rig, or equivalent equipped, with 6 5/8 inch diameter or larger hollow stem continuous flight augers in accordance with ASTM Method D1452-80 for soil investigations and sampling by auger borings. The auger and hammer will be steam cleaned prior to drilling each boring. The lithology and other pertinent data will be recorded on a field boring log in accordance, with ASTM Method D2488-84 for visual description and identification of soils. Borings will be logged by or under the direct supervision of a California Registered Geologist. Cuttings and other spoil from the borings will be placed back in the borehole if field screening indicates dean samples. If contaminants are detected from field screening, the cuttings will be stored in D.O.T. approved 55-gallon drums pending analysis. 7.2 Soil Sampling S°il samples will be cOllected through the auger in 2-inch brass sleeves driven in a split spoon sampler by a 140 pound hammer with a 30-inch drop in accOrdance with ASTM Methods D1586-84 for split-barrel sampling of soil and D1587-83 for thin walled tube sampling of 'soils. The brass sleeves and .... ~sampler will be' steam cleaned prior to each use. Soil samples will be driven at five foot intervals. The blow counts, recovery, and lithology will be recorded on field logs. Lithology will be described in accordance with the Unified Soil Classification System (USCS). One brass sleeve with s°il. from each interval will be capped, sealed, and labeled in accordance with EPA protocols, recorded on a Chain-of-Custody form, placed in a cooler at 4° centigrade or less, and transported to a California Certified Laboratory with the Chain-of-Custody for the spedfied analyses. Selected samples will be analyzed and the other samples will be held no more than fourteen days for further analyses if necessary. 7.3 Field screening Soil samples will be collected using three six-inch brass tubes installed inside a split spoon sampler. The middle sample tube will be immediately capped with a teflon liner separating the soil from the lid, and stored in an iced cooler The bottom tube will be used for lithologic description, and the top tube will be used for field screening. The material from the top tube will be placed in a mason jar to approximately 50 percent capacity, shaken, and stored for a period of 15 minutes. A standard headspace reading will be collected at this time and noted on the boring log. Field screening will be conducted using a Foxboro 128 GC/FID calibrated to a methane standard. 7.4 Soil Analyses The soil samples will be analyzed by Halcyon Laboratories, a California State Certified Laboratory in accordance with state guidelines and EPA protocols. The samples will be analyzed for Total Petroleum Hydrocarbons as gasoline, benzene, toluene, xylene, and ethylbenzene (BTEX) using the D.O.H.S. L.U.ET. Method 8015 and EPA Method 8020, respectively. 8.0 QUALI.TY ASSURANCE PLAN This section describes field and analytical quality-a, ssurance procedures fo be followed during the remediation. 8.1 SAMPLE' COLLECTION AND HANDLING PROTOCOL Proper sample collection and-handling are essential to assure quality of data obtained from a sample. Each sample therefore will be collected in a brass tube, preserved correctly for the intended analysis and stored for no longer than the permissible holding time prior to analysis.. Protocol to be applied in this project is described in Section 6.2. 8.2 SAMPLE IDENTIFICATION AND CHAIN OF CUSTODY PROTOCOL Sample'identification and' Chain of Custody procedures are designed to assure 'sample quality and to document sample possession from the time it is collected to the time of its ultimate disposal. The container for each sample submitted for analysis will have a label affixed with the identifying number or the number will be 'inscribed directlY on the container if feasible. The analytical laboratory will assign a separate sample number unique to that sample for internal sample coordination and identification. A description of the sample, including the sample number and other pertinent information regarding its collection and/or geologic significance will be written in field notes and/or a geOlogic boring log prepared by the site geologist. These field documents will be kept in a permanent project file. All samples will be analyzed by a State Certified Laboratory for the analyses requested. A properly completed Chain of Custody document will be submitted to the analytical laboratory along with the samples. The laboratory's assigned number will be properly entered on the form. A quality control officer at the lab will verify the integrity of the samples submitted, proper sample volume, correctness of containers used and properly executed Chain of Custody document. Pertinent information will be entered into a log bOok kept by the laboratory. 8.3 ANALYTICAL QUALITY ASSURANCE In addition to routine calibration of analytical instruments with standards and blanks, the analyst is required to run duplicates and spikes on 10 percent of analySes ~o assure an added measure of reliability and precision. Accuracy is verified through the following: 1. U.S. EPA and State certification of results; 2. Participation in inter-laboratory round robin programs; 3. "Blind" samples are submitted for analysis by the quality control officer on a weekly basis. These are prepared from National Bureau of Standards specifications of EPA reference standards; 4. Verification of results with an alternative method. 9.0 SITE SAFETY PLAN Appendix A contains a Site Safety Plan which complies with the Worker Right to Know Regulations and CAC Title 26.

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. AquaGeosciences, Inc. seeks to enter property described above for the purpose of a installing an electrically-heated catalytic oxidizer system at the site. Using the existing vapor extraction/inlet wells, AquaGeosciences, Inc. will manifold these wells to the vapor' extraction system. Drilling equipment will be brought to the site and operated by a subcontractor: Soils Engineering, Inc. 4700 District Boulevard Bakersfield, California 93313 C-57 License Number 253192 The SSP describes means for protecting all on-site personnel from deleterious contamination or personal injury while conducting on-site activities. As described below we will meet all requirements promulgated by the California Department of -Health Services. SITE BACKGROUND This prOperty is the former Automobile Club of Southern California. In 1991, RESNA was contracted to perform a Phase I Real Estate Site Assessment at the former Auto Club of Southern California site located at 2301 "F" Street, Bakersfield, California. RESNA indicated that a gasoline service station was previously operated in the northeast portion of the subject property. According to information obtained from the City of Bakersfield Building Department, the station was apparently demolished in 1977 and records were not available regarding underground tank removal or abandonment. On October 21, 1991, Spectrum Environmental Geophysics conducted a geophysical survey at the subject site to evaluate for underground tanks. Two (2) magnetic anomalies were detected; however, the ground penetrating radar signatures of the anomalies did not indicate the presence of underground storage tanks. On November 14, 1991 RESNA conducted a Phase II investigation which consisted of advancing three (3) soil borings to evaluate possible hydrocarbon contamination. Soil borings B-1 and B-2 were advanced to 20 feet and B-3 was advanced to 40 feet. Six (6) soil samples were submitted and ,analyzed for Total Petroleum hydrocarbons as gasoline (TPHg), BTEX, and Total RecoVerable Petroleum Hydrocarbons (TRPH). The analytical results indicated non-detect to low concentrations of hydrocarbons in the samples collected from soil borings B-2 and B-3. The highest concentrations were detected in boring B-l, which was subsequently (November 22, 1991) deepened to 45 feet. The analytical results from soil boring sample B-1 at 40 feet-indicated a TPFIg concentration of 2100 mg/kg. Based on the analytical results, the City of Bakersfield Fire Department, Hazardous Materials Division (BFDHMD) was notified. The BFDHMD sent a letter, dated December 2, 1991 to the Auto Club of Southern .California requesting that a site assessment be conducted in accordance with the Regional Water Quality Control Board (RWQCB) guidelines for evaluation of contaminant migration in the subsurface soils at the subject site. On February 3 and 4, 1992, RESNA advanced five (5) additional soil borings. Soil boring B-4 was advanced 5 feet west of soil boring B-1 to determine the vertical extent of hydrocarbon contamination. Due to auger refusal at 72 feet, two (2) consecutive non-detected soil samples were not obtained. Soil borings B-5, B-7, and B-8 were advanced to a depth of 30 feet each and B-6 was advanced to 35 feet, all to evaluate the lateral extent of contamination. Eight (8) soil samples were submitted and analyzed for TPHg and BTE×. The analytical results indicated that the highest concentrations were detected in the 60 foot sample of soil boring B-4. The concentrations detected in the 72 foot sample indicated rapid attenuation and the vertical limits of the plume had been estimated to be approximately 80 feet. RESNA, in their report dated February 24, 1992, presented an interpretation of the vertical and lateral extent of the gasoline impacted soil plume. Their interpretation indicated the plume had migrated to a depth of approximately twenty (20) feet. The volume of impacted soil is estimated to be 2,250 cubic yards containing an estimated 8,000 pounds of gasoline hydrocarbons. On August 5 and 17, 1992, RESNA advanced a total of five (5) vapor extraction wells. Two (2) of the wells are located in the center of the plume and are screened in separate zones. (shallow 15-45' and deep 50-70'). These wells are to be used as the primary extraction wells. The remaining three (3) wells are located around the perimeter of the plume and are screened from 15-55', 20-60', and 20-60', respectively. These wells are to be used as inlet wells. On September 10, 1992, RESNA set up a portable Granular ActiVated Carbon Vapor Extraction System on the site. The system was run for a period of two (2) hours under a SJVUAPCD permit exemption. 15 of 20 Based on the_data generated from this vapor extraction feasibility study, it appears that' the current well configuration will be sufficient to effectively remediate the entire impacted soil mass. BaS~d- on RESNA's findings, the presence of gasoline hydrocarbons in soils at the site _ are in. excess of the California .Regional Water Quality Control Board - Central Valley Region Leaking Underground Fuel Tank leaching potential guidelines. RESNA felt remedial action would be required by the interested regulatory agencies. In'situ __vapor extraction was_ . recommended as the most effective and cost competitive option available to cleanup ~the site. ~i' AGI reViewed' the Site AsSessment Report and Remedial Action Plan, dated - February 24, 1992 and a Vapor Extraction Pilot Test Report dated October 8, 1992, -~ prepared by.RESNA Industries. After reviewing the results and conclusions of the . vapor extraction feasibility study, AGI believes the soil vapor effluent data appeared to be Somewhat contradictory, therefore; in our proposal for a Request for Bid, requested by the Automobile Club of Southern California, AGI recommended that a electrically-heated catalytic oxidizer on-site for the remediation. AGI's proposal was accepted by the Auto Club of Southern California in December, 1994. -~!~SPONSIBILITY OF KEY PERSONNEL: All personnel on'site will have assigned responsibilities.

JOB HAZARD ANALYSIS: 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 '- ;': ~ gloves will be worn by persons collected 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 PID. Action levels requiring respiratory apparatus will be 5 ppm, in the breathing space. FUrthermore, no on-site smoking, open flame, or sparks will be permitted in order to prevent accidental ignition. RISK ASSESSMENT SUMMARY: Exposure to chemicals anticipated on-site include gasoline, 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 rog/kg (ppm), are listed below: --- COMPOUND TLV STEL TOXICITY ~ Gasoline 200 300 Benzene 10 25 4894 Toluene 100 50 5000 Xylene 100 150 4300 Benzene is considered an. extreme cancer hazard. EXPOSURE MONITORING PLAN: A Photo-Ionization Detector (PID) or a Flame-Ionizing Detector (FID) will be used to monitor vapor concentrations around site. Should concentrations exceed TLV's, protective measures will be taken. Passive dosimeter badges will be placed in downwind locations if PID reading indicate high levels of volatile organics in the breathing space. 17 of 20 , -;2 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 sample_s, .the on-site geologist will wear latex gloves. Hard hats will be worn by all Personnel on-site when in proximity of drilling equiPment. WORK ZONES AND SECURITY MEASURES: Access to the site will be.restricted to authorized personnel. Fencing, a set of cones, Placards, 'or wide. yellow tape, surrounding the site will define perimeter. The ~Project Managerl 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 possibly 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 equipment will be decontaminated before-each sample is taken and drilling equipment will be decontaminated before each boring is commenced. GENERAL SAFE WORK PRACTICES: - ' Drillers.and other 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 SSO, including respirator fit. Drilling and sampling equipment will be steam-cleaned before being brought on- site. Split-Spoon sampling equipment will be steam-cleaned before each use. Augers will be steam-cleaned between borings. The On-Site Geologist will oversee operations and log borings in consultation with drillers. 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 pre-site training session which will include all points of MSDS forms, contaminant properties, warning signs, health hazard data, risk for expos'tire, and emergency first"aid. All chemicals to be covered and the SSO will assure that everyone fully understands site hazards. MEDICAL SURVEILLANCE PROGRAM: --ACCording to CFR 29~ 1910A20, paragraph (f), employees who wear respirators 30 days __ or_more during one 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 will be required to have had a complete chemical physica! within the past year RECORD KEEPING: Doctune~tation 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-site training meeting. Exposure records_ on each job Will be kept for 30 years to meet requirements. -Included will be names and social security number of employees, medical evaluation, on-the-job logs from entry to exit, first aid administered, visits on-site by : outside persons, and personal air monitoring records.

This equipment has been previously permitted by the SCAQMD for use by Park Environmental Corporation (Park) for applications in Los Angeles County and also for ADWEST Technology, Inc., the manufacturer of the regenerative thermal oxidizer. Each existing groundwater monitoring well and/or vadose zone well to be utilized for vapor extraction will be manifolded to 4' Schedule 40 PVC pipe which will serve as the conduit for recovering soil vapors from treatment. This manifold system will connect to the vacuum side of 5 horsepower rotary positive blower. The gasoline vapors are extracted from the soil and the groundwater surface by enhancing volatization with reduced pressure and increased vapor flow through the soil. The blower exhaust containing the gasoline vapors feeds the positive pressure line to the centrifugal demister and flowmeter into the regenerative thermal oxidizer (Please refer to enclosed Figures 1, 2, and 3). After treatment by the thermal oxidizer, the treated well vapors are discharged to the atmosphere with emissions that meet or exceed SCAQMD criteria. G~NERAL INFORMATION FOR ALL SYSTEbIS The following information is in response to required information for permit application as described in "Vapor Extraction and Treatment Systems Used for Soil Decontamination' prepared by the SCAQ1V[D, dated September, 1990. .. a. The maximum flow rate of the contaminated flow stream is 300 scfm based on the specifications of the blower system. The flow rate will be determined prior to any system installation based on the results of a vapor extraction treatability study that will be conducted. b) The location of the blower, duct system and emission control devices will be shown on a site by site basis. c) The chosen blower size was based on vacuum requirements determined during a past vapor extraction treatability tests conducted using a 92 SCFM blower at other various sites in the Los Angeles Basin.
