The proposed work is to be performed for Ace Financial Corporation in compliance with guidelines of the County of Kern Department of Environmental Health Services (KCEHSD) Site Characterization and Remediation, UT-35, revised October 1994. This work plan was prepared accord!lng to all federal, state and local requirements and follows the Tri-Regional Board Staff Recommendations for Preliminary Evaluation and Investigation of Underground Tank Sites (January 1991). 6313 Schirra Court · Bakersfield, CA 93313 (805) 835-7700 fax (805) 835-7717 SM'tH 2.0 BACKGROUND On August !4, 1990, seven underground fuel tanks were removed by Groundwater Resources Inc. (GRI) from the above-referenced site as follows: two 10,000 gallon tanks (1 gasoline, 1 diesel), one 8,000 gallon gasoline, one 6,000 gallon diesel, two 1,000 gallon (contents unknown), and one 550 gallon waste oil tank. Soil saraples were collected in accordance with Handbook UT-30 under the supervision of a Kern County Department of Environmental Health Services (EHSD) inspector. Elevated hydrocarbons were detected beneath the main tank cluster, and beneath the dispenser islands. A site assessment was requested by the EHSD to assess the extent of hydrocarbon contamination beneath the site. Between November 28 to December 6, 1990, twelve soil borings were drilled to assess the.extent .of soil contamination at the Site. Water was encountered at a depth of 50-feet, and the boring was completed as a monitoring well (MW-I). Two more borings were completed as monitoring wells (MW-2 and MW-3) in accordance with Kern County Handbooks UT~35 and UT-50. Analytical results from soil samples analyzed indicated: a diesel vadose plume beneath the former main tank cluster approximately 20-.feet deep and 30-feet in diameter; a diesel plume beneath the former diesel dispenser islands approximately 25-feet deep and 15~feet in diameter; and a gasoline plume beneath the former gasoline dispenser islands approximately 45-feet deep and 50-feet in diameter. Periodic monitoring and sampling of the three monitoring wells indicated gasoline contamination in MW-2 on the east side of the site, wifft up to. 1-foot of gasoline product floating on the groundwater surface. 2 i:\8533ac¢\gwwkpln.doc In a Site Characterization/Remedial Action Plan dated January 14, 1991, GRI, who became RESNA Industries Inc. (RESNA), recommended excavation and bioremediation of diesel impacted soil on the west side of the site and vapor extraction of gasoline impacted soil on the east side of the site. Upon approval of The Remedial Action Plan by the EHSD, RESNA began implementing the plan at the subject site. RESNA began excavating hydrocarbon impacted soil on the west side of the site in March, 1993. Approximately 1500 cubic yards of soil were removed from the excavation which measured approximately 30 feet wide by 60 feet long by 20 to 22 feet deep. Approximately 1350 cubic yards of this soil was impacted with hydrocarbons. This impacted soil was stockpiled on-site for later bioremediation. During the excavation process monitoring well MW-1 was destroyed and abandoned in-place. Soil samples were collected from the sidewalls and base of the excavation and analyzed for Total Petroleum Hydrocarbons as diesel (TPHd) and for benzene, toluene, ethylbenzene, and xylenes (BTEX). The analytical results of these soil samples indicated that a minor amount of hydrocarbon impacted soil was left at the base of the excavation. RESNA concluded that the removal of the remaining diesel plume was not economically feasible and would not pose a risk to groundwater. The 1350 cubic yards of hydrocarbon impacted soil were bioremediated on-site in approximately five (5) 18-inch thick lifts. On the east side of the site RESNA installed a vapor extraction system to remediate the gasoline plume in the soil. The vapor extraction system was started on July 25, 1994 and shut-down in December, 1995. Approximately 3,246 pounds of hydroCarbons were removed through vapor extraction. RESNA drilled two confirmation soil borings to assess the effectiveness of the vapor extraction project in January, 1995. The results of the confirmation soil samples indicated that the gasoline impacted soil had been removed successfully. A closure letter dated March 9, 1995 was received from KCEHSD concerning for the soil plume. 'Smith Environmental (formerly RESNA) has monitored, purged and sampled monitoring wells MW-2 and MW-3 periodically over the last two years. The analytical results of the water 3 i:\8533ace\gwwkpln.doc SM'TH samples collected indicate that well MW-2 .still has elevated concentrations of gasoline in the groundwater (see Table 1 for past results). During a meeting with the KCDEHS in April, 1996 closure of the site was discussed. It was dete:mained that a more active approach to remediate the groundwater would be required prior to final closure of the site. Since March, 1996 Smith Environmental has been hand bailing product from well MW-2 on a weekly basis. 3.0 REGIONAL HYDROGEOLOGY According to the 1995 Report on Water Conditions, February 1996, prepared by the Kern Water Agency, the depth to groundwater at the Site location is approximately 210 feet. However, monitoring wells at the site have measured water levels at approximately 50 feet. It is therefore assumed that the first water encountered in the monitoring wells is part of a perched aquifer s. ystcm. The direction of groundwater flow fi~r the main unconfined aquifer is-generally'north to northwest. The gradient direction for the perched aquifer at the Site is unknown at this time. Prior to the removal of MW- I, the calculated grad:,ent direction trended to the northwest. 4.0 OBJECTIVES AND SCOPE OF WORK It is the objective of this proposed investigation to evaluate and report the presence, concentration, and aerial extent of the groundwater plume in the vicinity of the former dispenser islands. In addition, air sparge wells will be installed and tested to evaluate the effectiveness of sparging as a remediation alternative. The scope of work will include the following tasks. 4 i:\8533ace\gwwkpln.doc 4.1 Health and Safety Plan A site specific Health and Safety Plan (HASP) will be prepared according to 29 CFR 1910.120. Included in the HASP is a description of the personnel protective equipment and safety procedures which will be used during the field investigation, and a contingency plan including hospital information for emergencies. The HASP is provided as Attachment A. 4.2 Underground Service Alert Underground Services Alert (USA) will be contacted to locate subsurface utilities within the public right-of-way. Encroachment permits will be obtained for wells drilled off of the property. 4.3 Drilling and Well Completion A licensed drilling company will be contracted to drill up to six-.1 O-inch diameter borings using a hollow stem auger. Plate 2 shows the proposed locations of the borings. Three of the borings will be completed as groundwater monitoring wells (MW-4, MW-5 and MW- 6) while an additional three borings will be completed as air sparge wells (AS-l, AS-2 and AS-3). Well construction diagrams for the monitoring wells and air sparge wells are presented on Plates 3 and 4. The monitoring wells will be located to assess the lateral extent of the groundwater plume. Drilling will be observed by a State of California Registered Geologist or a field geologist under the supervision of a registered geologist. The field geologist will log the soil encountered using the Unified Soil Classification System (USCS). 4.3.1 Monitoring Well Construction A 10-inch boring will be advanced to approximately 65 feet or fifteen feet below the water level, as measured in an adjacent well. Each well is to be constructed of 4-inch schedule 40 PVC casing. Twenty feet of (~.020" slotted casing will be installed with 5 i:\8533ace\g,n~kpln.doc SM # approximately 35 feet of blank casing to the :surface. A sand filter pack will be placed in the annular space from the bottom of the boring to a minimum of 2-feet above the slotted interval. A minimum of three feet of bentonite will be placed above the sand pack with cement grout to the surface. Each well head will be protected with a twelve inch traffic rated well box. A monitoring well construction diagram is presented on Plate 3. 4.3.2 Air Sparging Well Each air sparging well is to be constructed using a combination of air sparge injection piping and a vapor extraction well. A 1 O-inch boring will be advanced to approximately 58 feet and a one-inch schedule 40 PVC pipe, with a three-foot slotted sectiOn, will be placed at the bottom of the boring. A sand pack will be placed around the sparge pipe to a depth not less than six inches above the slotted section. A bentonite seal will be placed above the filter pack to approximately 40 feel: below grade. A two-inch vapor extraction well will be installed above the bentonite seal[. This well will be constructed of schedule 40 PVC with a ten-foot slotted section. The filter pack will be placed a minimum of two feet above the slotted interval. A minimum of three feet of bentonite will be placed above the sand pack with cement grout to the surface. An eighteen inch traffic rated well box will be placed over the well head. An air sparge well construction diagram is presented on Plate 4. 4. 4 Soil Sampling Since the soil plume has been assessed and re:mediated, soil samples will not be collected for chemical analysis. Selected samples may be collected to assess soil properties or determine lithology. A photoionization detector will be available to monitor the presence of hydrocarbon vapors in the event that they are encountered. 6 i:\8533ace\gwwkpln.doc SM'TH 4.5 Groundwater Sampling Upon completion, each monitoring well will be fully developed, purged and sampled. MW-2 and MW-3 will also be purged and sm-npled. All water samples will be collected in 40 ml VOA bottles, labeled, chilled and transported under a chain of custody to a California state certified laboratory. Each sample will be analyzed using EPA Method 602 and 8015 modified. 4. 6 Well Survey All of the monitoring wells will be surveyed for relative location and well head elevation. The results of the survey will determine the current groundwater gradient of the perched aquifer. 4. 7 Air Sparge Test Upon completion of the- air .sparge .wells,-a test will be performed to assess the effectiveness of sparging for the remediation of the groundwater plume. Each well will be tested by introducing pressurized air into the aquifer while applying a vacuum to the unsaturated soil. Measurements of the extracted vapor stream will be collected before and during the introduction of compressed air. The absolute pressure will be monitored in nearby wells to determine the effective radius of influence for both the sparging and vapor extraction. The sparge testing equipment will consist of an air compressor or blower capable of producing up to 40 cfm of air and a 100 cfm vapor extraction blower. The extracted vapors will be treated with granular activated carbon prior to release to the atmosphere. Each sparge well will be tested for approximately 4 hours, or until readings sufficiently stabilize. A pilot test permit will be obtained from the San Joaquin Valley Unified Air Pollution Control District prior to testing. 7 i:\8533ace\gwwkpln.doc SM H 4. 7 Reporting A report will be prepared describing procedures, methods, results, interpretations, conclusions and recommendations for additional work. 5.0 HEALTH AND SAFETY All Smith Environmental employees that will work at the site received the Health and Safety training required by OSHA for hazardous waste site operations (29 CFR 1910.120). Petroleum and gasoline fuel constituents are the identified hazardous substances at this site. Highly volatile components, such as benzene, pose the greatest health hazard. Because of the outdoor location and the intermittent nature of drilling operations, it is not considered likely that personnel will be exposed to elevated levels of hydrocarbon vapors for any length of time. Under these conditions personnel will work under "Class D" protection. Smith Environmental will use a PID to monitor ambient concentrations of organic vapors. Personnel will have access to air-purifying respirators (APR) with organic vapor canisters that can be donned if conditions warrant. The detailed site specific Health and Safety F'lan (see Attachment A), will be distributed to and adhered to by all Smith Environmental personnel, subcontractors, and all site visitors. A "tailgate" safety meeting will be held at the site prior to commencing operations during which all site hazards and the Health and Safety Plan will be reviewed. 6.0 PROPOSED WORK SCHEDULE It is anticipated that drilling and sampling can begin within two weeks after receiving verbal authorization of this work plan. Field activiti!es can be completed in approximately two weeks. 8 i:\8533ace\gwwkpln.doc SB H The analytical laboratory reports should be received ten days after the field work and the report of findings should be completed within the following two weeks.

The site was a former retail gas station dispensing gasoline and diesel products. Portions of the site are asphalt covered while approximately 3/4 is dirt. Plate 2 provides a Plot Plan. 1.2 SITE HISTORY A site assessment was requested by the EHSD to assess the extent of hydrocarbon contamination beneath the site. Between November 28 to December 6, 1990, twelve soil borings were drilled to assess the extent of soil contamination at the Site. Water was encountered at a depth of 50-feet, and the boring was completed as a monitoring well (MW-I). Two more borings were completed as monitoring wells (MW-2 and MW-3) in accordance with Kern. County Handbooks', UT-35 and UT-50. Analytical results from soil samples analyzed indicated: a diesel vadose plume beneath the former main tank cluster approximate, ly 20-feet deep and 30-feet in diameter; a diesel plume beneath the former diesel dispenser islands approximately 25-feet deep and 15-feet in diameter; and a gasoline plume beneath the former gasoline dispenser islands approximately 45-feet deep and 50-feet irt diameter. Periodic monitoring and sampling of 'the three monitoring wells indicated gasoline contamination in MW-2 on the east side of the site, with up to 1-foot of gasoline product floating on the groundwater surface. In a Site Characterization/Remedial Action Plan dated January 14, 1991, GRI, now RESNA Industries Inc. (RESNA), recommended excavation and bioremediation of diesel impacted soil on the west side of the sit,; and vapor extraction of gasoline impacted soil on the east side of the site. This Remedial Action Plan was approved by the EHSD and RESNA performed the following remedial action at the subject site. RESNA began the excavation of hydrocarbon impacted soil on the west side of the site in March, 1993. Approximately 1500 cubic: yards of soil were removed from the excavation which measured approximately 30 feet wide by 60 feet long by 20 to 22 feet deep. Approximately 1350 cubic yards of this soil was determined in the field to be impacted with hydrocarbons. This impacted soil was stockpiled on-site for later bioremediation. During the excavation process monitoring well MW-1 was destroyed and abandoned in- place.

SECTION 4 JOB HAZA_RI) ANALYSIS 4.1 MAJOR CHEMICAL COMPOUNDS The major chemical hazards at this site are the presence of benzene, toluene, xylenes and ethylbenzene and gasoline. Material data sheets (MSDS) for these compounds .are in Attachment A. Several of these chemicals are known carcinogen and precautions are necessary to limit exposure to this compound. NOTES 1) Inh - Inhalation Ing- Ingestion Abs - Absorption through the skin 2)., TLV-TWA - Threshold Li~nit Value-Time Weighted Average) 3) ACGIH - American Conference of Govermnental Industrial Hygienists 4.2 INHALATION HAZARD The vapor and dust concentrations thai: might be encountered during sampling and mitigation procedures may exceed currenlly recommended exposure limits. Respiratory protection must therefore be used in the work area. Engineering and administrative controls to abate windbome dust will .be employed. These will include items such as water spray from a 500 gallon tank and/or administrative controls such as reducing site activities that produce windbome dust. 4.3 DERMAL EXPOSURE HAZARD Contact of sufficient duration to cause significant absorption of toxic components is highly unlikely. Repeated daily or prolonged contact over a period of time may however, lead to absorption through the skin, irritation and dermatitis. For this reason direct skin contact shall be avoided by wearing protective gloves and clothing. However, if contact does occur, the exposed areas shall be wa:shed with soap and water and rinsed thoroughly. 4.3.1 Eye Contact If eye contact is made with any chemical materials at the site, the eye shall be flooded with water for at least 15 minutes. Medical attention shall be obtaine, d as soon as possible. 4.3.2 Skin Contact Skin exposure shall be 'treated by washing with soap and water. Any contaminated clothing shall be removed and affected areas washed with soap and water. 4.4 OTHER HAZARDS Attention must be paid to other possible hazards on the site including, but not limited to: - improper use of hand tools rotating machinery such as pm~nps dehydration of the personnel tripping on objects or open ditches falling objects from the overhead work lack of oxygen through blockage of the mask - Overhead power lines 4.5 HEAT STRESS PREVENTION The SSO shall monitor ambient temperature and use the following work/rest regimes as a guide. For ambient temperature below 80oF, standard rest breaks (e.g. 15 minutes every 4 hours) should be used. For temperature above 80oF, the following regime should be followed. Temperature Work Rest Comments (a) 80 to 85oF 2 hr. 5 min. Review heat stress in a safety meeting. Schedule a beverage break every 2 hrs., at a minimum. 80 to 90oF 2 hr. 15 min. Seated rest. Drink at least 8 ounces at each break. Above 90oF 1.5 hr 15 min. As stated above. Rest area to be shaded. SECTION 5 JOB HAZ.~d~D SUMMARY Exposure to chemical hazards may occur when contaminated soils are brought to the surface during drilling and during the vapor extraction process. As each of task begins, the potential risk of exposure increases. Consequently, level C personal protective equipment shall be available at the site. If monitoring of the breathing zone establishes another action level, the personal protection level may be upgraded. Nearby residents or workers are at a sufficient distance that they shall be at no significant risk. The SSO shall determine if any further action is required. SE.CTION 6 EXPOSURE MONITORING PLAN 6.1 DRILLING The exposure monitoring activities shall[ be conducted or directed by the SSO during those activities that require such monitoring. At a minimum, the breathing zone shall be monitored for organic vapor during drilling and excavation activities. This shall be accomplished by use of a Foxboro OVA, HNU or PID portable analyzer. 6.2 ACTION LEVELS Actions levels for explosive hazards are set at 25% of the lower explosive limit (LEL). In the event that enough combustible vapor is present to sustain readings at or near 25% of LEL work shall cease until an evaluation is perform by the SSO and a determination can be made. Actions levels for organic vapors in the breathing zone shall based on readings obtained by the portable equipment mentioned. The FID instrument determines the total organic vapor present in the breathing zone. Readings of 0 to 5 ppm in the breathing zone shall be considered level D without respirators. Readings of 5 ppm or greater for 5 minutes or longer in the breathing zone shall trigger an action level to upgrade to level C or modified level D with respirators. Using a PID instrument which is sensitive to-the aromatic components, readings in the neighborhood of 50 ppm for five minutes in the breathing zone will trigger a change to Class C protection. SECTION 7 PERSONAL PROTECTIVE EQUIPMENT The respiratory and skin protection requirement shall be initially set at level "D" without respirators. This indicates that inhalable airborne substances are known, and concentrations of chemicals in the atmosphere are not expected and are well below TLV- STEL levels. The use of the following personal protection equipment is mandatory. 7.1 EQUIPMENT REQUIRED FOR FIELD PERSONNEL - Hard hat - Boots (with steel toes) - Eye protection - Half-mask air purifying respirator with organic vapor cartridge on site 7.2 LEVEL C PERSONAL PROTECTIVE EQUIPMENT Half-mask air purifying respirator with organic vapor cartridge when necessary. Tyvek protective coveralls - Gloves (latex and/or nitrile) 7.3 EQUIPMENT TO BE USED OR AVAILABLE ON SITE: - First-aid kit with eyewash - Fire extinguisher - Construction tape and barrier,,; to delineate work zone - A vehicle must be kept on site: when personnel are working - A cellular or public phone to be available on site for communication purposes with off site facilities. FID or PID Sanitation facilities portable or public SECTION 8 SITE CONTROL 8.1 WORK ZONE The site area shall be controlled to reduce the possibility of exposure to chemical and/or mechanical hazards present at the site. Work areas shall be delineated to protect the general public from exposures and hazards. If level C protection becomes necessary then zones and access points shall be clearly indicated (see Plate 3). A restricted area t~,r contamination reduction shall be maintained at the exit to the exclusion zone. Protective clothing and equipment as required by this health and safety plan shall be worn at all times in the exclusion zone and shall only be removed in the designated decontamination corridor at the exit. The areas outside the contamination reduction area, is considered a clean area. SECTION 9 DECONTAMINATION PROCEDURES Decontamination of equipment shall be conducted when necessary. However, if it becomes necessary to upgrade to a protect level greater that "D", then an Exclusion Zone shall be established and an area in the Contamination Reduction Corridor (CRC) shall be used as a decontamination area. The CRC controls access into and out of the Exclusion Zone and confines personnel and equipment decontamination activities to a limited area. The CRC boundaries shall be marked and all personnel entering and leaving the site must do so through this corridor. 9.1 DECONTAMINATION OF PERSONNEL IN LEVEL C Exit from the exclusion zone through CRC shall include the following steps: 9.1.1 While in the Exclusion Zone near the CRC. - Deposit equipment used on site. - Outer boot and glove wash. - Outer boot and glove rinse. - Tape removal if used. - Boot cover removal. - Outer glove removal. 9.1.2 Exit the Exclusion Zone to the Contamination Reduction Zone for further decontamination. Remove garment Wash inner glove Rinse inner glove - Face piece removal - Inner glove removal 9.1.3 Exit the Contamination Reduction Zone to the Support Zone. - Wash face and hands. .. ! 9.2 DECONTAMINATION OF EQUIPMENT Insofar as possible, measures shall be taken to prevent commination of equipment. Any delicate instrument, which cannot be decontaminated easily should be protected while it is being used. It should be bagged and the bag taped and secured around the instrument. Openings are made in the bag for sample intake. Larger equipment shall be decontaminated with water or steam under pressure. These activities shall be conducted on an impermeable surface such as plastic. The rinsate shall be collected and stored in fifty five (55) gallon drums. The drams shall be label as to its contents and staged for disposal or recycli[ng. SECTION 10.0 GENERAL SAFE WORK AND STANDARD OPERATING PRACTICES Site health and safety plan implementation will be the responsibility of Smith Environmental. If Smith Environmental health and safety personnel find that the H&S plan is not being implemented by the subcontractors, the subcontractors will be instructed to suspend further work. A meeting to evaluate the noncompliance will be scheduled with the subcontractors Project Manager. During the meeting the personnel will reach an agreement to either; * Revise the Health and Safety ['lan, * Modify the Health and Safety Plan, * Request review by an Industrial Hygienist, * Leave the Plan unchanged. The subcontractor will then implement the Plan as modified. 10.1 SITE SAFETY ORIENTATION MEETING All field personnel from Smith Environmental and the subcontractors must attend a safety orientation meeting before commencing the field work. The meeting will be scheduled and conducted by the Site Safety Officer and is to include an overview of the site history, the potentially hazardous compounds, their potential mode of ingress into the body, protective equipment requirements, and emergency response equipment. All individuals who do not have respirators and who may be required to wear them, will not be allowed on the site until they are provided with and fit tested for respirators by their respective employers. 10.2 ACCIDENT/PERSONNEL EXPOSURE REPORTS The Site Safety Officer must be informed of all exposures to potentially hazardous material and all accidents whether or not any injury was caused. After investigation of the cause of the accident, he will take all immediate possible steps for the mitigation of the repeat of the accident and proceed with the preparation of an accident report. In the event off a serious or fatal injury resu][ting frOm accidents on the site, the relevant CAL/OSHA requirements for accident reporting must be met. The Project Manager will also be informed at the earliest possible ti~ne. 10.3 PROHIBITED ACTIVITIES No eating, drinking, or smoking is allowed in the restricted zone, and only allowed off the site after personal decontamination ha:5 taken place.

VOC Concentrations; Monitoring at the site of the VOC's in the air stream before and after treatment will be done using a portable Foxboro Model 108 FID type meter. This unit will be calibra~l to hexane and has a range of 1 ppmv to 10000 ppmv. A gas chromatograph, SRI Model 8610 equipped with both FD and PID detectors will be used for compliance with the permit to operate. Inlet and exhaust gases will be monitored for total organic compounds. Working to Restore Nature ATC Application 601 Golden State Highway . . : . . :..- -.. · :. :... " Page Two ' ' ' Description of Operation Phase 1 The insitu decontamination.of soil will[ be accomplished by venting the vapor extraction wells to a Model TX-300 (300 cfm) thermal oxidizer. VOC contaminated air will be pulled from five vapor extraction wells installed as shown in the attached plot plan. Each of the wells will be plumbed to the remediation system with 2" dia. schedule 40 PVC piping. The individual wells will be manifolded at the enclosed compound. A flow control valve, pitOt tube and sampling valve will be installed downstream of the manifold. From the manifold the combined vapor flow will be passext through a vapor/liquid separator and then into the primary blower. An LEL sensor dowrtstream of the blower will control a fresh air inlet damper to adjust LEL levels. The vapors are then passed through a flame arrester and into the combustion chamber. Natural gas is used as a supplementary fuel source to maintain a ~combustion temperature of 1450 °F. Residence time in the combustion chamber is 1.0 second. When influent VOC concentrations drop below 15 % LEL, a catalytic module can be inserted to reduce supplemental fuel costs. The air stream will be preheated to 750 °F prior to entering the catalyst. Phase 2 The remediation system may be switched to granular activated carbon if the extracted hydrocarbon concentrations decrease to low levels and stabilize. The switch will be made if the costs for carbon replacement is less than the operating costs for the thermal oxidizer. The granular activated carbon system ~411 utilize carbon steel canisters, 88" in height and 48" in width, each bearing a load of 2000 lbs of vapor phase carbon. The maximum throughput for the canister is 500 CFM. the canisters model V2000, will be supplied by Bameby & Sutcliffe (a scaled drawing ~md hexane isotherm are attached). Two canisters will be plumbed in series. The blower rates, VOC concentrations and residence time will be limited so that the first canister will reduce the VOC concentrations to approximately lppmv. A breakthrough criteria defined at 2% LEL effluent concentration at the first canister provides for acceptable loading of the f'u'st canister while avoiding increased effluent at the system stack. At an influent concentration of 28 ppmv at 400 CFM, the calculated VOC load in the first canister is 120 lbs. This produces a calculated time to loading of 33 days. The system will be monitored at a frequency of two times the loading rate, or every 14 to 16 days. When loading becomes apparent, the effluent fi'om the second canister will be allowed to increase to the limit set in the authority to consu~ct to allow for maximum loading of the carbon. When the limit is reached, the carbon will be removed by the supplier and replaced. A regenerative blower rated to extract 400 CFM at 2 inches of Hg will be used to pull vapors from the wells and through the carbon canisters. It will be placed downstream of the carbon canisters to prevent escape of VOC's in the event of a line separation and to avoid compression heat transfer to the carbon. Working to Restore Nature ATC Application · 601 Golden State HighWaY Page Three Operating Schedule During the-initial '-'shakedown"-period,-ahe system willbe-operated between8 AM-and 5- PM Monday through Friday. When stable operation is achieved, the system will operate on a 24 hr/day, 7 days/week basis. It is expected that the soil clean-up operation will last 9 months. Expected Emission of Air Contaminants Phase 1 Fresh air will be mixed with the soil-gas :;tream as needed by the automatic dilution system. All calculations of energy consumption and emissions are based upon the maximum 300 scfm rates. Inlet concentrations are calculated from samples collected during a vapor extraction pilot test. Gas .samples were analyzed on RESNA's gas chromatograph, SRI Model 8610, equipped with both FD and PID. Under normal operating conditions, the influent concentration will be 25% of LEI., as total VOC's (6.1 lxl0-4 lbs/cu ft.). This corresponds to a VOC inlet rate of 11.0 lbs per hour. Tests on the extracted soil gases have shown that the benzene to total VOC ratio is 0.025. The expected benzene inlet concentration is 1.53 x 10.5 lb/cu ft and the flow rate is .275 lbs per hour. Outlet concentrations are based upon the manufacturer's standard destruction efficiency of 97%. Total.non-methane hydrocarbon emissions concentrations will be 1.83 x 10.5 lb/cu ft (0.330 lbs per hour). Benzene emissions will be 4.59 x 10-7 lb/cu ft (0.0083 lb per hour). Phase 2 Outlet concentrations for non-methane hydrocarbon emissions concentrations will be 0.000316 lbs/hr and Benzene emissions will be 7.9 x 10-6 lb/hr. Fuel~ ~nd B0rners Used A. Bumers: One Eclipse MVTA (medium velocity tempered air), with a maximum rate of heat input at 752,000 BTU/hr. Equipment and its operation is described in the attached General Specifications. B.

The pot is equipped with a sight glass and a brass ball cock for draining off liquid. An. automatic purap with level switches can be fitted to the knock 'out pot on .request.' 'The automatic pump feature 'wOuld bE billed as an optional component. Air Filters Replaceable air filters are furnished with the unit and are located in the knock out pot__anO on_ th_e _t)vo _di_lution air inlets. The Knock out pot filter can be ·readily changed by removing the top of the lmock out pot. The air dilution filters are external and can also be readily changed. Baker Furnace maintains a supply of replacement filters in stock at all times. Three Wall Valving with Auton atic Air Dilution Motor actuated three-way valves are to be installed to supply clean air to purge the combustion system prior to ignition of the pilot and to restrict VOC laden air from entering the Thermal Oxidizer until it reaches its operating temperature. The valves automatically switch over at a preset temperature which is configured into the process temperature controller. Two of the valves are proportionally modulated and are linked to oxygen and L.E.L. sensors. The sensors are connected to digital microprocessor based P.I.D. controllers which proportionately modulate the butter- fly valves around a setpoint which has been selected. L.E.L. and oxygen levels are simply set on the P.I.D. controllers and then maintained automatically by the amount of dilution air which enters the Oxidizer. Supplemental Fuel and Vapor Inlet Pipe Sizes Please refer to our general arrangement drawing #101212 included with these speci- fications for specific pipe sizes for the #100 through #500 Thermal Oxidizers. Air Flow Pitot Tube An in line air flow tube is provided to interface with a .square root extractor and transmitter. The pitot tube measures differentiai pressure and then sends its air - pressure signals to the square root extractor where the signal is cubed and then sent on to the chart recorder. The chart recorder displays the result in cubic feet per _ minute. Combustion System An Eclipse MVTA (medium velocity tempered air) combustion burner is to be supplied with the Thermal Oxidizer utilizing a modulating gas butterfly valve, spark ignition, piloting and FM approved flame safety relays. The combustion burner is also equipped with a FM approved gas fuel train. The burner will fire on propane or natural gas. Inlet gas pressure should be 1-5 PSI at the regulator on the fuel train. Please refer to· the fuel usage charts provided with these specifications for data regarding the use of supplemental l fuel versus VOC concentrations at the influent~t° ~e Oxidizer. The charts_~ are available for both Catalytic and Direct fired operation. - Control Panel A complete Three Phase control panel is included with a choice of 208/230/460 _ volts (or 220 volt Single Phase ff required) and would consist of the'following component parts: · . . . . : . : .

Locking glass enclosure over instruments Optional Catalytic "Plug In" Module -- Baker Furnace has developed a "plug in" Catalytic Module which can be readily installed inside our existing direcl~ fired Oxidizer with a minimum of effort. The catalyst inside the module is a monolithic material which significantly reduces the - pressure drop across it and provides maximum surface area for the gasses which are to be catalyzed. - Each module is designed to fit do~-n inside the Thermal Oxidizer chamber and bolt in place between the cone and stack section. Please refer to our enclosed drawing which shows the relationship of thc Catalytic Module to the Thermal Oxidizer. Once the Module is bolted in place, the only remaining task is to reduce the temperature setting on the process and high limit controllers. The entire process to _- install the Catalytic Module should take approximately one (1) hour. The use of the "Catalytic Module Option" will greatly reduce supplemental fuel _ usage when the concentrations of VOC's are at low levels because the temperature requirement for a Catalyst system is approximately one-half that of a direct fired unit. We will only need to preheat the incoming vapors to 750° F. prior to 'the cata- _ lyst versus 1450° F. in the direct fired unit. The delta T (change in temperature) is then reduced by almost one-half which will-save a great deal of supplemental fuel. Our Thermal Oxidation unit is equipped standard with a "High Limit" temperature controller which will protect the ca~alyst in the event the catalytic process becomes overly exothermic and the temperature attempts to run away. -- Baker Furnace can provide installation (on site) of the Catalytic Module at a nomi- nal cost. Please refer to the charts provided with these specifications for supple- men ,tal'fuel uSage versus VOC concentrations for both Catalytic and Direct Fired ~ Oxidizers to ascertain the projected savings by nsing our Catalytic Module. RefraCtory Lining A 5" thick 2300° E ceramic fiber lining is installed in the Thermal Oxidizer to keep the exterior surface at a safe temperature. The ceramic fiber material has a very low K value which means it is an excel:lent insulator (does not store or transfer heat readily). A ceramic throat is fitted ~thin the Oxidizer ' at a Spqcific location and is sized for velocity.of 15 ft/sec. The combustion chamber is sized for 10 ft/sec. Optional "Parafax" Telemetry System We offer, as an option, a remote monitorh~g and reporting system which interfaces with the various instruments in the control panel and will fax the data to any desired location-up to 99 times per day. 'The "Parafax' system does 'not'require a computer phone modem or the use of a dedicated computer to extract the operating data on the Oxidizer. A floppy disk is confiigured in a IBM compatible computer and then installed in the "Parafax' unit. Fax reports are then sent automatically to a phone number which has been selected and configured onto the floppy disk. The repo _rts will show a initial, low and average input for the parameter being monitored. A standard deviation is also shown as well as a fmal reading. We can monitor temperature, air flow, L.E.L. and Oxygen ].evels for the oxidizer. A total of 8 inputs can be configured for the "Parafax'. Steel Construction All components are manufactured from heavy grades of hot rolled A-36 steel plate. Weldments are accomplished under an argon CO2 purge to assure gas free homoge- neous bonding of components. The Oxidizer is to be of a cylindrical design with flanged connections for maintenance purposes in the future.' All components will be sldd mounted on a heavy channel base with slots for forklift access. Operating Temperatures Direct fired Oxidizers are designed to operate at 1450° E (AQMD requires minimum 1400° E) while the Catalytic units are designed to operate at 700° E (at the entry to the Catalyst). Optional Trailer We have a tandem axle 6' x 10' trailer ava~:lable with electric brakes and all neces- sary lighting. The trailer has been outfitted with a steel deck and all components are bolted securely in place. Each Oxidizer component can be removed for mainte- nance purposes if necessary. Please refer to our general arrangement drawing #101212 for specific overall dimensions c~n the trailer. The trailer as well as the Thermal Oxidizer is painted with federal safety blue enamel unless a substitute color is specified. Residence Time for Vapors Our Oxidizers are designed for 1 full secon~d of residence time. Los Angeles AQMD requires 0.7 seconds for Thermal Oxidizers.. Destruction Efficiencies Direct fired units have destruction efficiencies above 99% while the Catalytic units are advertised to have rates above 97%. We generally see higher, than 97% .destruc- tion efficiency for Catalytic operation and we are still exceeding: the criteria set forth by AQMD at 97% destruction. Safety Interlocks and Safety Devices on - Baker Thermal Oxidi:zers - Air Proving Switch A U.L., FM and CSA approved air proving switch is provided to ascertain that the positive displacement blower is operational. In the event that the blower fails, the - 'air proving 'switch will "open" the limits circuit thereby causing the unit to shut down the sppp!em_en~tal~fuel li~n_ e_ mad to_ close thevaporline to the Oxidizer. ....... High/Low Gas Pressure Switch A U.I~, FM and CSA approved gas pressure switch is provided in the supplemental fuel train which will also "open" the limits circuit in the event an unusually high or low gas pressure condition exists. High Temperature Limit Controller · A U.L. and FM approved high temperature limit controller has been engineered into the limits circuit to shut down the, Oxidizer in the event a high temperature condi- tion exists. The limit controller must be manually reset (per FM requirement) _ before the Oxidizer can be rendered operational. While in the high limit condition, the Oxidizer will not utilize supplemental fuel nor will vapors be allowed to enter the Oxidizer until the controller is ~manually reset. FM Approved Flame Safety Device -~- Our Thermal Oxidizers utilize a FlVl approved and U.L. recognized flame safety device which lights the combustion burner on the Thermal Oxidizer after a 30 second purge (5 air changes) of the combustion chamber. The burner has a 15 - second ignition trial which lights pi~lot only. In the event the pilot does not light, the flame safety device locks out the supplemental fuel train thereby reducing the potential for an explosion. The main gas valve in the supplemental fuel train -- cannot open unless the pilot has 'been established. Flame monitoring is 'accom- plished via a 3/16" diameter incone], flame rod. L.E.L. Combustibles Sensor and Controller A catalytic bead L.E.L. sensor and controller has been integrated into the limits - . circuit. In the event that the alarm set point for L.E.L. has been exceeded, the L.E.L. controller "opens" the limits circuit.which subsequently closes the vapor butterfly valve and temporarily shuts down the combustion burner until the L.E.L. - returns to a safe level below the alarm setpoint. _ Varec Flame Arrester A U.L. approved flame arrester has been piped into the vapor, extraction discharge line in CloSe proximity, to the Thermal Oxidizer. The flame arrester prevents propa- gation of flame back to the source. FMApproved Supplemental Fuel Train A FM supplemental fuel train is provided with the Oxidizer and is fitted with an approved safety shut off valve for the main gas. The shut off valve will close in 0.3 seconds in the event of flame .failure. The main.gas valve, is held shut with a 150 lb. . ... force to'assure aright_cloSure. , Oxygen Sensor and Proportional Dilution Valve A O2 sensor and P.I.D. controller is provided to monitor oxygen content in the vapor stream. We require'18% oxygen. (minimum) in the stream for sufficient -combustion of volatiles. In-the event the oxygen content of the vapor stream drops off significantly the O~_ controller opens a proportionally'modulated butterfly valve and lets in dilution air to bring the oxygen content up to a satisfactory level. Alarm Cardin Process Temperature Controller We have integrated an alarm card into the process temperature controller to restrict the entry of volatiles into the Oxidizer ~mtil it reaches its correct operating tern- perature (14000 E). This is accomplished by setting an alarm value equal to 1400 in the controller. When this value (in temperature) is reached, the process controller sends a signal to a butterfly valve drive motor which opens the valve and allows the vapor stream to enter the Oxidizer. Vapors cannot enter the Oxidizer at any tern- perature below which the alarm value h~ been set. This prevents the incomplete burning of hydrocarbons which occurs at lower operating temperatures.

(RESNA) is requesting a change in the air abatement equipment to be used at the subject site. The original equipmenl~ to be used was a 300 SCFM Baker Furnace Inc. Thermal Oxidizer. RESNA now is proposing to use an Air Kinetics Inc. (AKI) model AKI 200 Ex Thermal Oxidizer at the site. The specifications for this equipment are included for your review. The design flow of this unit is 250 SCFM with a 15 Hp Lampson Blower. We would like to get this approval within the next two weeks. If you have any questions concerning this letter, please contact RESNA at (805) 835-7700. Sincerely, Robert J. Becker Project Manager, R.G. # 5076 Enclosures: _A _KI_ 200 Ex Th.e_rmal Oxi~zer Specifications cc: Mr. Walt Heisey, Ace Financial Corporation VZU SYSTEM 200 VAPOg EXTRACT[ON SYSTEM The VEU system 200 is a 200 scfm thermal oxidation unit designed to thermally destruct vapors with concentrations of gasoline up to 40,C~0 ppmv. The unit includes a Lampson 15 HP vacuum blower, a Cincinnati fan 600 $CFM supplemental air blower, and an AKI incinerator with a residence time at 800 $CFM of 0.6 seconds. Natural gas or propane can be used to heat the unit with no Supplemental fuel needed when gasoline concentrations in the influent are in excess of about 13,000 ppmv. The Lampson blower is a belt drive unit with a wide range in RPM by using different combinations of sheaves on the drive shal~. Currently the unit is set to operate at about 2250 RPM at which speed it was producing about 200 sefm with a suction pressure of about 40 inches of water. Depending on the resistance to flow up to 300 to 400 sefm may be pumped through the unit. Provided the concentration is l~ then about 20,000 ppmv in the influent flow the system can handle between 300 to 400 sejha. The l_ampson blower and motor system is very quiet relative to a Rotron blower which was previously mounted on the unit. The unit was last located immediately across a narrow street from residential housing and no our knowledge there were no complaints. The unit was so quiet that it was h.ardly distinguishable form stree, t noise 25 feet from the unit. To further reduce noise an insulation box is available which completely encloses the blower. Controllers on the unit include a temperatm:e controller on the supplemental fuel system and an oxygen controller on the supplemental ak system. Monitoring includes temperature, oxygen, total flow, and total petroleum hydrocarbons. 'I~0tal flow is monitored using a Sponsler flow meter. The TPH is measured using a Beckman infra-red detector. A Raffiseh FID is on board and can be used to monitor influent or influent continuously or episodically,, as needed. Chart recorders for temperature, oxygen, total flow and toutl petroleum hydrocarbons are set to monitor 7 day periods. A small air pump is located on the unit to supply zero air for calibration of the analyzers, an air supply for the FID. and air for cooling and oxygen reference for the oxygen analyzer. The system is mounted on a goose neck trailer which is about 35 feet in length. A 6 well header which has control valves and sampling pot, s can be used to extract from as many as 6 wells independently. An extension stack is provided which extends the stub stack to about 15 feet above the ground _sm'face ...... _ ...... , ..... · ............ The unit uses up to about 600,000 BTU of fuel when there is no BTU in an incoming stream of 200 sefm. The gas pressure to the unit should be in the range of 2 to 4 psi. A regulator on the unit can be used to reduce the incoming pressure where it is slightly in excess of 5 psi. A 220 volt 3 phase power source is _needed to provide electricity to run the vacuum blower. The electrical system for the unit uses 220 volt 3 phase power provided by .a 1130 amp circuit.-( -Where 220 volt 'is not available 208: volts xs sxfffieient). The unit has been operated in the San Francisco and South Coast Air Quality. Management Districts and permits have been. obtained from these air quality agencies. Operating efficiencies for "I'PH is greater than 99%. SPECEB$. EEC.

Becker RESNA 1500 S. Union Avenue ' Bakersfield, CA 93307 Re: Authority to Construct #S-2108-1 Project Description: Soil Remediation Operation Located at 601 Golden State Avenue in Bakersfield- Request to Change Equipment Dear Mr. Becker: RESNA's request to install an Air Kinetics, inc. thermal oxidizer for soil remediation at 601 Golden State rather than the Baker Furnace model listed on the Authority to Construct has been reviewed by the Air Pollution Control District. A comparison of the two systems indicates that they are similar enough in BTU and flow rate that the change will trigger no offsets, no toxics will exceed the established · risk factors, and no changes to ATC conditions will be necessary. Therefore RESNA has SJVUAPCD approval to proceed with the change. Thank you 'for your cooperation. Should you have any questions, please telephone Mr. Thomas Gaff of Permit Services at (805) 861-3682. Sincerely, Seyed Sadredin Director^ of Permit Services f, P.E.
