INTRODUCTION Groundwater Technology, Inc. has been contracted by ARCO Products Company to provide environmental consulting for an assessment of subsurface conditions at their facility #0583. The assessment was requested by Kern County Environmental Health Services because laboratory analysis of soil samples from previous investigations indicate hydrocarbon-bearing soil is present at the site. This workplan outlines site background, proposed assessment procedures and sampling protocol, and worker safety considerations. SITE BACKGROUND The site is located at 3220 Ming Avenue in Bakersfield, California (Figures 1 and 2). Groundwater Technology completed a preliminary assessment of soil conditions at the site in March, 1987 (see letter of March 12, 1987). The assessment consisted of drilling three borings (B1-B3) at the locations shown in Figure 2. One sample from each boring was submitted to the laboratory for analysis of benzene, toluene, ethylbenzene, and xylenes (BTEX) and total petroleum hydrocarbons as gasoline (TPHG). The samples collected from borings B1 and B2 had non-detectable concentrations of the analytes of interest and B3-35' had a concentration of 2157 rog/kg TPHG. In September, ~987, boring B3 was deepened to 50 feet and a fourth boring (B4) was drilled near one of the service islands (see report of October 5, 1987). Gasoline hydrocarbons were not detected in the soil samples collected from boring B4 or below a depth of 40 feet in boring B3. Laboratory results from these investigations are summarized in Table 1. Existing gasoline storage tanks were removed in January, 1991 (see report of February 7, 1991). Laboratory analysis of samples collected beneath tanks, dispensers, and piping indicate concentrations of BTEX and TPHG are below detection limits in all samples analyzed with the exception of the samples from the southern ends of tanks 2, 3, and 4 (Figure 2). Concentrations of TPHG in soil collected at these locations range from 1.4 to 2,000 rog/kg. Laboratory results are presented in Tables 3 and 4, and in Figure 2. Kern County Environmental Health has recently requested that further site characterization be completed. Characterization Workptan ARCO Products Company Apri[ 19, 1~1 -~=~ GROUNDWATER ~ ..&~'~.

Topography in the region is flat, and no natural bodies of water adjoin the site. The station is located in a commercial area and is approximately 3,000 feet southwest of the nearest school. HYDROGEOLOGY The site overlies alluvial fan deposits of the Kern River (Figure 3). Sediments underlying the region consist of fluvial deposits including silt, sand and gravel. Sediments encountered during drilling and excavation activities at the site consist primarily of well-sorted medium- to coarse-grained sand. A clayey sand layer is present from 2 to 3 feet below grade. An unconfined aquifer is present below the site at a depth of approximately 170 feet (Figure 4). The gradient of this aquifer is generally toward the southeast (Figure 5). Shallow, perched water has not been identified in the vicinity of the site (Kern County Water Agency, 1990).

Data from borings completed during previous investigations, and from a visual inspection of the open tank excavation, indicates the lateral extent of the plume is limited to the area shown on figure 6. The borings will be drilled to a minimum depth of 30 feet. If hydrocarbons persist below 30 feet and if drilling conditions permit, the boring will be deepened until 10 feet of uncontaminated soil is penetrated. No drilling fluids will be used during boring completion. The borings will be back-filled with sand-cement grout upon completion of work. SAMPLING The borings will be sampled every 5 feet with a split-spoon sampler. The sampler will be filled with brass sample rings. The material from one sample ring will be described and field screened with a ph°toionization detector (PID) for volatile organic content. A second ring will be sealed at each end with a teflon sheet and plastic cap. The cap will be secured Characterization gorkptan ARCO Products Company Aprit 19, 1991 4 GROUNDWATER TF~HNOLOG¥, INC. with polyethylene tape and the sample will be preserved on ice. All samples collected in the boring which defines the vertical extent of hydrocarbons will be submitted for analysis in an effort to provide vertical definition of the plume. Two samples will be analyzed from the other boring; the sample which exhibits the highest volatile organic content, as indicated by the PID, and the deepest sample. An additional sample will be analyzed from this boring if hydrocarbons are suspected at depths greater than 30 feet. All samples will be analyzed by a state-certified laboratory as described in the next section. Between sampling events, equipment will be cleaned using a three-bucket wash system. In this system, the rings and samplers are scrubbed with a brush in a bucket of detergent, rinsed in a second bucket of tap water and given a final rinse in a bucket of distilled water. LABORATORY ANALYSIS The soil samples selected for analysis will be shipped via overnight courier to GTEL Environmental Laboratories in Torrance, California (Cert. #723). The samples will be analyzed for TPHG and BTEX utilizing EPA method 8015/8020. Detection limits for these analyses will be 10 mg/kg for TPHG, and 0.05 mg/kg for BTEX. Standard chain-of-custody procedures will be followed. WASTE MANAGEMENT The drill cuttings from the borings (less than 1 yd3) will be stored on site in appropriately labelled drums pending the results of the analysis of cuttings samples. If contamination is encountered, drilling augers will be steam-cleaned upon completion of drilling activities. The rinsate from cleaning will be collected in appropriately labelled 55-gallon drums and disposed of by ARCO. Dependant on the concentrations of hydrocarbons in the drill cuttings, and with County approval, ARCO will either passively aerate the cuttings until clean or dispose of them in an appropriate landfill.

WORK SCHEDULE Immediately following approval of the proposed plan a licensed drilling company will be scheduled to perform the necessary drilling. The drilling is anticipated to require 1 day. Kern County Environmental Health Services and Underground Service Alert will be notified at least 48 hours prior to commencement of work. Laboratory analyses will require approximately 15 days following submission of the samples to the laboratory. Characterization WorkpLan ARCO Products Company Aprit 19, 1991 6 TECHNOLOGY, INC.

ARCO PRODUCTS COMPANY - MING AVENUE Site Safety Plan January 2, 1991 Surface and Equipment Contamination: Contact with contaminated surfaces, or surfaces suspected of being contaminated should be avoided. This includes walking through, kneeling or placing equipment in puddles, mud, discolored surfaces, or on drums and other containers. Eating, smoking, drinking and/or the application of cosmetics is prohibited on this site in the immediate work area. This reduces the likelihood of contamination by ingestion. Exposure - Heat Stress: Since climatic changes cannot be avoided work schedules will be adjusted to provide time intervals for intake of juices, juice products and water in an area free from contamination and in quantity appropriate for fluid replacement. Heat stress may occur even in moderate temperature areas and may present any or all of the following: Heat Rash: result of continuous exposure to heat, humid air, and chafing clothes. Heat rash is uncomfortable and decreases the ability to tolerate heat. Bo Heat Cramps: result of the inadequate replacement of body electrolytes lost through perspiration. Signs include severe spasms and pain in the extremities and abdomen. Co Heat Exhaustion: result of increase stress on the vital organs of the body in the effort to meet the body's cooling demands. Signs include shallow breathing; pale, cool, moist skin; profuse sweating; dizziness. De Heat Stroke: result of overworked cooling system. Heat stroke is the most serious form of heat stress. Body surfaces must be cooled and medical help must be obtained immediately to prevent severe injury and/or death. Signs include red, hot, dry skin; absence of perspiration; nausea; dizziness and confusion; strong, rapid pulse. Can lead to coma and death. ARCONING. SSP/#19 8 GROUNDWATER --}{--]E TECHNOLOGY, INC.

Solutions may include a 0.1% salt and water solution or commercial mixes such as Gatorade and Squench. Be Cooling devices to aid the natural body ventilation. Cooling occurs through evaporation of perspiration and limited body contact with heat-absorbing protective clothing. Utilize fans and air conditioners to assist in evaporation. Long, cotton underwear is suggested to absorb perspiration and limit any contact with heat- absorbing protective clothing (i.e., coated Tyvek suits). em Provide hose-down mobile shower facilities to cool protective clothing and reduce body temperature. De Conduct non-emergency response activities in the early morning or evening during very hot weather. Ee Provide shelter against heat and direct sunlight to protect personnel. Rotate workers wearing protective clothing during hot weather. Exposure - Cold Stress: Work schedules will be adjusted to provide sufficient rest periods in a heated area for warming up during operations conducted in cold weather. Also thermal protective clothing such as wind and/or moisture resistant outerwear is recommended to be worn. If work is performed continuously in the cold at or below -7°C (20°F), including wind chill temperature, heated warming shelters (tents, cabins, company vehicles, rest rooms, etc.) shall be made available nearby and the worker should be encouraged to use these shelters at regular intervals the frequency depending on the severity of the environmental exposure. The onset of heavy shivering, frostnip, the feeling of excessive fatigue, drowsiness, irritability, or euphoria, are indications for immediate return to the shelter. When entering the heated shelter the outer layer of clothing shall be removed and the remainder of the clothing loosened to permit sweat evaporation. A change of dry work clothing shall be provided as necessary to prevent worker from returning to their' work with wet clothing.

NG.$SP/#19 14 GROUNDWATER TECHNOLOGY, INC. ARCO PRODUCTS COMPANY - MING AVENUE Site Safety Plan January 2, 1991 7.0 CHEMICALB OF CONCERN ?.1 Health Effects Potential health effects from a chemical exposure are dependant on several exposure factors such as: toxicity of substances, duration of exposure, concentration during exposure and the overall health of the person exposed. The chemicals commonly at this site are: Gasoline, Benzene, Toluene, Ethylbenzene, and Xylene. The following is a health analysis of these chemicals. Additional information on these chemicals can be found in the Material Safety Data Sheet located in Appendix E. Gasoline constituents can be divided into five major groups: alkanes, alkenes, cycloalkanes, aromatics and additives. The aromatics are the constituents generally regarded to be of greatest toxic concern. The major aromatics in gasoline are benzene, toluene, ethyl benzene and xylene. Of these, benzene is considered to be the most toxic. One characteristic effect of gasoline and its aromatic constituents is their ability to irritate the skin when repeated or prolonged exposure occurs. Benzene Benzene can enter the body through inhalation, ingestion and skin contact. Studies have noted that chronic exposure to benzene vapor can produce neurotoxic and hematopoietic (blood system) effects. Other effects can include headache, dizziness, nausea, convulsions, coma and possible death if exposure is not reversed. One significant effect from chronic benzene exposure is bone marrow toxicity. There is also an association between chronic exposures to benzene and the development of certain types of leukemia. Toluen~ Inhalation exposure to toluene vapor can produce effects such as central nervous system depression. Depending on exposure factors signs and symptoms can include headache, dizziness, fatigue, muscular weakness, incoordination, drowsiness, collapse and possible coma. Toluene can be a skin and mucous membrane irritant and studies have shown that high levels of toluene exposure can cause liver and kidney damage. ARCO~ [NG. SSP/#19 15 GROUNDWATER TECHNOLOGY, INC. ARCO PRODUCTS COMPANY - MING AVENUE Site Safety Plan January 2, 1991 ?.1 Health Effe=ts (Continued) Ethylbenzene Exposure to ethyl benzene at high vapor concentrations may produce irritation to the skin, eyes and upper respiratory tract. Overexposure to ethyl benzene vapors can produce central nervous system depression with symptoms of headache, nausea, dizziness, shortness of breath and unsteadiness. Prolonged skin exposure to ethyl benzene may result in drying and cracking of the skin (dermatitis). Solvent resistant gloves should be worn during sampling to prevent exposure to the skin. Xylenes Depending on exposure factors, inhalation exposure to xylene vapor may produce central nervous system excitation followed by depression. Exposure to xylene vapor can produce dizziness, staggering, drowsiness and unconsciousness. At very high concentrations, xylene vapor may produce lung irritation, nausea, vomiting and abdominal pain. Xylene is not known to possess the chronic bone marrow toxicity of benzene, but liver enlargement and nerve-cell damage have been noted from chronic overexposure. ARCOM ! NG. SSP/#19 16 GROUNDWATER TECHNOLOGY, [NC. ARCO PRODUCTS COMPANY - MING AVENUE Site Safety Plan January 2, 1991 8.0 GAS/VAPOR MONITORING PROCEDURES The greatest potential hazards to safety and health at this site are: 1. Exposure to chemical vapors - through inhalation 2. Exposure to chemical contamination - through skin contact and ingestion. Ongoing air monitoring during project tasks will provide data to ensure that vapor concentrations are within acceptable ranges and will provide adequate selection criteria for respiratory and dermal protection. 8.0.1 If PID readings exceed 100 ppm, a NIOSH approved air-purifying respirator with organic vapor cartridges must be worn by all site workers within any area where monitoring results exceed 100 ppm. 8.0.2 If PID readings exceed 750 ppm, level B protection will be required. Personnel must leave site immediately and contact site safety officer or Health & Safety Manager for further instructions. 8.0.3 Respirator cartridges will be changed once per day as a minimum. This can be accomplished at the end of the work day during respirator decontamination. If odor breakthrough is detected while wearing the respirator or breathing becomes difficult, change cartridges immediately. 8.1 Tasks Performed Within a Confined Space When site work takes place in a confined space the air must be monitored for (a) oxygen level; (b) explosive vapors; and (c) toxic vapors. The following air monitoring procedures must be followed before entering a confined space. ae Oxygen Level: Monitor for % Oxygen with a O2/LEL Meter to ensure a minimum oxygen level of 19.5%. Oxygen level monitoring will be done at the top, middle and bottom of the enclosed space to determine if there is a minimum acceptable oxygen level of 19.5% prior to entry. If oxygen is less than 19.5%, do not enter the space. AI~CON~NG. SSP/#19 17 GROUNDWATER TECHNOLOGY, INC. ARCO PRODUCTS COMPANY - MING AVENUE Site Safety Plan January 2, 1991 be Co Explosive Vapors: Monitor for % of'Lower Explosive Limit (LEL) with a 02/LEL M~er to determine whether vapor concentrations within the confined space exceed 20% of the LEL. If readings exceed 20% LEL, personnel shall shut off accessible equipment, leave the site immediately, and contact the fire department. Toxic Vapors: Monitor the air within the confined space for organic vapors with a PID or FID following guidelines stated in Section 8.0 (above) to decide on the respiratory protection needed. Enter the space only if the oxygen level is at or above 19.5%, the %LEL is below 20%, the toxic vapor concentration is determined, and the proper respiratory protection is worn. PID or FID readings will be taken at the top, middle and bottom of a vault, shed, or other confined space to ensure that vapors do not exceed acceptable levels. Ail monitoring equipment must be calibrated and maintained in accordance with manufacturer's recommendations. ARCOH! NG. SSP/#19 18 GROUNDWATER TECHNOLOGY, INC. ARCO PRODUCTS COMPANY - MING AVENUE Site Safety Plan January 2, 1991 9.0 HEALTH AND S~%FETY REQUIREMENTS 9.1 Medlcal Monitoring Program Ail Groundwater Technology, Inc. field personnel are required to have annual medical evaluations in accordance with the company,s Health and Safety Program policy. Additional re-evaluation will be considered in the event of chemical over-exposure while working on this site. The petrochemicals typical of these facilities can affect specific organ systems producing characteristic health effects. The medical evaluation will, therefore, focus on the liver, kidney, nervous system, blood systems, and skin and lung function. Laboratory testing will include complete blood count, and applicable kidney and liver-function tests. Other tests include skin examination. 9.2 Training Ail personnel working at this site should have received a minimum of 40 hours of initial hazardous waste activity instruction, and a minimum of three days of field experience under the direct supervision of a trained, experienced person. Personnel assigned to the site will also receive eight hours refresher training per year. On-site managers and supervisors directly responsible for employees engaged in hazardous waste operations have received an additional eight hours of supervisory training. These training requirements comply with the OSHA Hazardous Waste Operations and Emergency Response regulation, 29 CFR 1910.120. The initial 40-hour training and the 8-hour annual refresher training includes specific details on the following: Regulatory Requirements First Aid/CPR Confined Space Entry Respiratory Protection Air Monitoring Decontamination Procedures Hazard Communication Toxicology These specifications are then complimented with actual hands-on experience with the use of personal protective equipment and air monitoring equipment. 9.3 Work Zones Access Access within a 5-foot radius of any on-site operation is prohibited to all but Groundwater Technology, Inc. field personnel and subcontractors.

The Carbon Treatment System is equipped with an emergency shut-off. The system will shut off automatically when the non-methane TPH vapor concentrations in the intermediate line reach 5% of the Lower Explosive Limit (LEL) for gasoline as recorded by the system monitors. The suggested equipment for decontamination and spill response procedures includes: wash tubs (3) plastic sheets trash bags scrub brushes detergent sorbent booms (as applicable) The carbon system is a closed system where no chemicals are used. potential for a spill is minimal and thus spill containment is not addressed in this Site Safety Plan. The 9.6 Drilling Procedures A Dig-Alert authorization number must be obtained prior to drilling. During the drilling operation, two persons (one designated as "driller" and the other as "helper") must be present at all times. The helper (whether Groundwater Technology, Inc. personnel or subcontractors) must be instructed as to the location of the emergency shut-off switch. Every attempt must be made to keep unauthorized personnel from entering the work area. If this is not possible, the operation should be shut '' down until the area is cleared. The area where the operation is taking' place shall be cordoned off with a barricade. The Site Safety Officer' or the Field Team Leader has the authority and the responsibility to ARCON 1NG. SSP/#19 2 0 II--I L I GROUNDWATER ~ TECHNOLOGY, INC. ARCO PRODUCTS COMPANY - MING AVENUE Site Safety Plan -- January 2, 1991 shut down the drilling operations whenever a hazardous situation is deemed present. The mast of the drilling rig must maintain a minimum clearance of 20 feet from any overhead electrical cables. All drilling operations will cease immediately during hazardous weather conditions such as high winds, heavy rain, lightening and snow. Hart hats shall be worn at all times. during noisy operations. Hearing protection shall be worn If product is encountered during the drilling operation, all work must stop in order for employees to upgrade personal protective equipment to Level C. A full-face respirator should be worn in order to prevent the inhalation of vapors and to provide face and eye protection from splashes. Coated tyvek suits, gloves, and overboots should be worn to prevent skin contact with the soil. Air monitoring must be performed in the work area to document · breathing-zone concentrations. If air monitoring results indicate concentrations greater than 700 ppm, then Level B respiratory protection will be implemented. Respirator cartridges must be changed at the end of a work period or if "breakthrough" occurs. If employees experience continuous cartridge "breakthrough", then the employees' work procedures and the level of respiratory protection must be re-evaluated by the Site Safety Officer and the Health and Safety Manager in order to determine the necessity of upgrading to Level B respiratory protection. 9.7 Electrical Equipment and Ground-Fault Circuit Interrupters Ail electrical equipment and power cables in and around wells or structures suspected of containing chemical contamination must be intrinsically safe and equipped with a three-wire ground lead, rated explosion-proof for hazardous atmospheres. In accordance with OSHA 29 CFR 1926.404, approved ground fault circuit interrupters (GFCI) must be used for all 120 volt, single phase, 15 and 20 ampere receptacle outlets on the site which are in use by employees. Receptacles on the ends of extension cords are not part of the permanent wiring and therefore, must be protected by GFCI's whether or not the extension cord is plugged into permanent wiring. The GFCI is a fast-acting circuit breaker which senses small imbalances in the circuit caused by current leakage to ground, and in a fraction of a second shuts off the electricity. However, the GFCI will not protect the employee from line-to-line contact hazards (such as a person holding two "hot" wires or a hot and neutral wire in each hand). The GFCI does provide protection against the most common form of electrical shock hazard - the ground fault. It also provides protection against fires, overheating, and destruction of insulation on wiring. ARCC~ING. SSP/#19 21 l c. ARCO PRODUCTS COMPANY - MING AVENUE Site Safety Plan January 2, 1991 GFCIs can be used successfully to reduce electrical hazards on construction sites. Tripping of GFCIs - interruption of current flow - is sometimes caused by wet connectors and tools. It is good practice to limit exposure of connectors and tools to excessive moisture by using watertight or sealable connectors. Providing more GFCIs or shorter circuits can prevent tripping caused by the cumulative leakage from several tools or by leakages from extremely long circuits. (Adapted from OSHA 3007; Ground-Fault Protection on Construction sites, 1987.) 9.8 Fire Prevention During equipment operation, periodic vapor concentration measurements should be taken with an explosimeter or combustimeter. If at any time the vapor concentrations exceed 20% of LEL, then the Site Safety Officer or designated field worker should immediately shut down all operations. Only Factory Mutual (FM) approved fire safety cans will be used to transport and store flammable liquids. All gasoline and diesel-driven engines requiring refueling must be shut down and allowed to cool before filling. Smoking is not allowed during any operations within the work area in which petroleum products or solvents in free-floating, dissolved or vapor forms, or other flammable liquids may be present. No open flame or spark is allowed in any area containing petroleum products, or other flammable liquids. 9.9 General Health Medicine and alcohol can increase the effects of exposure to toxic chemicals. Unless specifically approved by a qualified physician, prescription drugs should not be taken by personnel assigned to operations where the potential for absorption, inhalation, or ingestion of toxic substances exists. Drinking alcoholic beverages is prohibited. Drinking alcoholic beverages and driving is prohibited at any time. Driving at excessive speeds is always prohibited. Skin abrasions must be thoroughly protected to prevent chemicals from penetrating the abrasion. It is recommended that Contact Lenses not be worn by persons working on the site. 9.10 MSDS Information Material Safety Data Sheets (MSDS) on chemical substances encountered at the site shall be made available to all persons (including subcontractors) working at the site. These MSDSs Shall be enclosed within this site safety plan in Appendix E. For emergency situations not specifically addressed by this site safety plan, refer to MSDS recommendations for action information. ARCON]NG.SSP/#19 2 2 GROUNDWATER TECHNOLOGY, INC.

EXCAVATION AND TRENCHING POLICY- CALIFORNIA SAFE CODE OF PRACTICES Although many of the rules and regulations pertaining to excavation and trenching operations in the State of California closely parallel Federal Standards, this policy specifically pertains to California operations. It shall be the policy of Groundwater Technology, Inc. to ensure that all GrOundwater Technolo~ employees and subcontractors comply with the provisions within the California Code of Regulations, Title 8, Chapter 4, Subchapter 4 - Construction Safety Orders. It is inevitable that remediation procedures for which Groundwater Technolo~ is retained will involve some aspect within the jurisdiction of the Construction Safety Orders. Such operations may include: trenching, vault construction, tank removal, and excavation of contaminated soils. DEFINITIONS - EXCAVATION, TRENCHES, EARTHWORK Bank - a mass of soil rising above a digging level. Bell Hole - an additional excavation made into the sides or bottom of a trench to provide additional work space. Belled Excavation - a part of a shaft or footing excavation, usually near the bottom and bell- shaped, that makes the cross-sectional area at that point larger than that above. Benching - a method of excavation whereby the faces of an excavation or trench are widened progressively outward with respect to the bottom of a specific series of horizontal and vertical cuts to provide protection against the hazard of moving ground. Braces for Excavation - the horizontal members of the shoring system, the ends of which bear against the uprights or stringers. Earthwork - the process of excavating, mo~Sng, storing, placing, and working any ~pe of earth materials. Excavation - a man-made cavity or depression in the earth's surface, including its sides, walls, or faces formed by the removal of materials, and producing unsupported earth conditions by reason of such removal. If installed forms or similar structures reduce the depth-to-width relationship, the excavation may become a trench. Expl~rati0n Shaft - a shaft created and used for the purpose of obtaining subsurface data. EX&TRa\'CH.POL/MG #2 L-;[_J T£CHNOLOG~: I.XC. Geotechnical Specialist (GTS) - a person registered by the State as a Certified Engineering Geologist, or a Registered Civil Engineer trained in soil mechanics; or an engineering geologist or civil engineer with a minimum of 3 years applicable experience working under the direct supervision of either a Certified Engineering Geologist or Registered Civil Engineer. Hard Compact - all earth material not classified as running soil. Hydraulic Shoring - a shoring system using hydraulic cylinders, planks, rails, plywood, or steel beams to support the excavated wall of trenches. Laooino - boards which are joined, side-by-side, lining an excavation. Running Soil - earth material where the angle of repose is approximately zero, as in the case of soil in a nearly liquid state, or dry, unpacked sand which flows freely under slight pressure. Running material also includes loose or disturbed earth that can be only contained Mth solid sheeting. Shaft - an excavation under the earth's surface in which the depth, is much greater than its cross-sectional dimensions (such as those formed to serve as wells, cesspools, certain foundation footings, and under streets, railroads, buildings, etc.) Shore - a supporting member that resists a compressive force imposed by a load. Shoring System - a temporary structure for the support of earth surfaces formed as a result of excavation work. Sides, Walls, and Faces - the vertical or inclined earth surfaces formed as a result of excavation work. Sloping - a method of excavation xvhereby the faces of an excavation of trench are laid back to provide protection from mo,~-ing ground. Spoil - the earth material that is removed in the formation of an excavation. Stringers - the horizontal members of the shoring system whose sides bear against the uprights. Stringers are sometimes called whalers. Strut - a structural member designed to resist forces, either tensional or compressional. Trench - an excavation made below the surface of the ground. In general, the depth is greater than the width at the bottom, but the width of a trench at the bottom is not greater than 15 feet. EX&TRNCH.POL/tMG #2 GROUNDWATER TECHNOLOGY. INC. Trench Shield - a protective device which shields workers from the effect of ground movement and which can be moved along as work progresses. .Uprights - the vertical members of the shoring system.' Whaler - a structural member in a horizontal or nearly horizontal position used for stiffening or securing other components of concrete forms, excavation sheeting, or similar temporary structures. EXCAVATION PROCEDURES (also trenches, shafts, and other earthwork) Prior to beginning an excavation, the location of all underground utilities and other underground hazards shall be deterrNned. A hazard assessment shall be conducted by a qualified person to evaluate the potential exposure to employees who may work in or around the excavation. The excavation shall also be inspected by a qualified person after each rain or other hazard-increasing event to evaluate the potential hazards from slides or cave-ins. Anytime an employee enters an excavation 5 feet or greater in depth, that employee must be protected by a system of shoring, sloping, benching, or alternative means addressed in #15 below. The conditions in #4 above, ,a-ill also require Groundwater Technology to obtain the necessary excavation perrn/t and/or notification procedures with Cai-OSHA. Excavated materials shall be prevented from falling back into the excavation. Spoils should be placed no closer than 2 feet from the edge of the excavation. Work which is conducted Mthin the excavation should be under the direct supervision of a qualified person who is capable of modifying the shorino or sloping system. = A convenient and safe means of egress shall be provided for employees working within an excavation 4-feet deep or greater. This may consist of a stainvav, ladder, or ramp located within 25 feet of lateral travel. ' Any employee working in the vicini .ty of an excavator shall not be in a position where that employee m/ght fall into contact with the moving parts of that excavator. Employees shall also be wearing a reflective vest. EX&TR,NCH.POLi~IG #2 10. An adequate means of water drainage shall be implemented to reduce the likelihood of run-off entering the excavation. This shall hold true during the rainy season. If the accumulation of water could pose a hazard to employees, the situation should be controlled prior to resumption of operations. 11. All shoring systems shall incorporate the soil specifications and conditions for that particular site. The installation of shoring systems shall be conducted in such a way that the employee is properly protected from the potential of cave-ins. Additionally, the removal of the system shall follow the same requirement. 12. 13. If the excavation exceeds 20 feet, or if an alternative shoring, sloping, or benching system is utilized, a civil engineer currently registered in California shall prepare detailed plans showing the materials and methods to be utilized (Appendix A). The detailed plans in #12 above, shall be available for inspection at the site. 14. Shoring shall be installed in accordance with Table 1-6 located Mthin Appendix B, or as detailed in plans and specifications prepared by a State of California Registered Ci',51 Engineer in accordance w/th engineering criteria within Appendix A. 15. If protective shields, (i.e., trench shields) are to be utilized for the protection of employees within an excavation, a cml engineer registered in California must prepare the necessary calculations and designs prior to the use of such equipment. 16. }tV~l en .sI0.ping or benc.hing are utilized in lieu of a shoring system, the slope shall be east mree-quarter l~orizontal to one vertical for excavations up to 8 feet, unless the instability of the soil requires a slope flatter than 3/4:1. For excavations greater than 8 feet but less than 12 feet, a slope of 1:1 shall be utilized (Appendix C).

We have completed our initial review. The next step in the claim review process is to conduct a compliance review. Compliance Review: Staff reviews, verifies, and processes claims based on the priority and rank within a priority class. After the Board adopts the Priority List, your claim will remain on the Priority List until your Priority Class and rank are reached. At that time, staff will conduct an extensive Compliance Review at the local regulatory agency or Regional Water Quality Control Board. During this Compliance Review, staff may request additional information needed to verify eligibility. Once the Compliance Review is completed, staff will determine if the claim is valid or must be rejected. If the claim is valid, a Letter of Commitment will be issued obligating funds toward the cleanup. If staff determine that you have not complied with regulations governing site cleanup, you have not supplied necessary information or documentation, or your claim application contains a material error, the claim will be rejected. In such event, you will be issued a Notice of Intended Removal from the Priority List, informed of the basis for the proposed removal of your claim, and provided an opportunity to correct the condition that is the basis for the proposed removal. Your claim will be barred from further participation in the Fund, if the claim application contains a material error i-esulting from fraud or intentional or negligent misrepresentation. Record keeping: During your cleanup project you should keep complete and well organized records of all corrective action activity and payment transactions. If you are eventually issued a Letter of Commitment, you will be required to submit: (1) copies of detailed invoices for all corrective action activity performed (including subcontractor invoices), (2) copies of canceled checks used to pay for work shown on the invoices, (3) copies of technical documents (bids, narrative work description, reports), and (4) evidence that the claimant paid for the work performed (not paid by another party). These documents are necessary for reimbursement and failure to submit them could impact the amount of reimbursement made by the Fund. It is not necessary to submit these documents at this time; however, they Will. definitely be reqUired prior to reimbursement. Compliance with Corrective Action Requirements: In order to be reimbursed for your eligible cc;sts of cleanup incurred after December 2, 1991, you must have complied with corrective action requirements of Article 11, Chapter 16, Division 3, Title 23, California Code of Regulations. Article l 1 categorized the corrective action process into phases. In addition, Article 11 requires the responsible party to submit an California En vironmental Protection Agency Recycled Paper Arco Products Company -2- MAY l 6 2000, investigative workplan/Corrective Action Plan (CAP) before performing any work. This phasing process and the workplarffCAP requirements were intended to: 1. help the responsible party undertake the necessary corrective action in a cost-effective, efficient and timely manner; 2. enable the regulatory agency to review and approve the proposed cost-effective corrective action alternative before any corrective action work was performed; and 3. ensure the Fund will only reimburse the most cost-effective corrective action alternative required by the regulatory agency to achieve the minimum cleanup necessary to protect human health, safety and __the_eny. ironment ..... - In some limited situations interim cleanup will be necessary to mitigate a demonstrated immediate hazard to public health, or the environment. Program regulations allow the responsible party to undertake interim remedial action after: (1) notifying the regulatory agency of the proposed action, and; (2) complying with any requirements that the regulatory agency may set. Interim remedial action should only be proposed when necessary to mitigate an immediate demonstrated hazard. Implementing interim remedial action does not eliminate the requirement for a CAP and an evaluation 'of the most cost- effective corrective action alternative. Three bids and Cost Preapproval: Only corrective action costs required by the regulatory agency to protect human health, safety and the environment can be claimed for reimbursement. You must cOmply with all regulatory agency time schedules and requirements and you must obtain'three bids for any' required corredtive action. Unless waived in writing, you are required to obtain preapproval of costs for all future corrective action work. If you do not obtain three bids and costPreapproval, reimbursement is not assured and costs may be rejected as ineligible. If you have any questions, please contact me at (916) 227-4411.

This assessment was requested by Kern Courity Environmental Health Services. (County) laboratory analysis of soil samples from previous investigations indicate hydrocarbon-bearing soil is present at the site. The assessment involved drilling two soil borings,, collection of soil samples, laboratory analysis, and evaluation of the laboratory data. The following report documents background information and the findings of the investigation. SITE BACKGROUND The site is located at 3220 Ming Avenue in Bakersfield, California (Figures 1 and 2). Groundwater Technology completed a preliminary assessment of soil conditions at the site in March, 1987. The assessment consisted of drilling three borings, numbered BI, B2 and B3, at the locations shown in Figure 2. One sample from each boring was submitted for laboratory analysis of benzene, toluene, ethylbenzene, and xylenes (BTEX) and total petroleum hydrocarbons as gasoline (TPHG). The samples collected from borings B1 and B2 did not yield detectable concentrations of the analytes of interest. However, the sample from a depth of 35 feet in boring B3 yielded a concentration of 2157 mg/kg TPHG. In September, 1987, boring B3 was deepened to 50 feet and a fourth boring (B4) was drilled near one of the service islands (see report dated October 5, 1987). Gasoline hydrocarbons were not detected in the soil samples collected from' boring B4 or below a depth of 40 feet in boring B3. Laboratory results from these investigations are summarized in Appendix C, Table Cl. Existing gasoline storage tanks were removed in January, 1991 (see report dated February 7, 1991). Laboratory analysis of samples collected beneath tanks, dispensers, and piping indicated concentrations of BTEX and TPHG were below detection limits in all samples analyzed with the exception of the samples from the southern ends of tanks 2, 3, and 4 (Appendix C, Figure C1). Concentrations of TPHG in soil collected at these locations Characterization Report ARCO Products Company June 25, 1991 ~ GROUNDWATE R TECHNOLOGY ranged from 1.4 to 2,000 mg/kg. Laboratory results of samples collected during the tank removal phase of the investigation are presented in Appendix C, Tables C2 and C3. SITE CHARACTERISTICS GEOGRAPHY The site is located on the alluvial plain of the Kern River. Topography in the region is fiat, and no natural bodies of water adjoin the site. The station is located in a commercial area and is approximately 3,000 feet southwest of the nearest school. HYDROGEOLOGY The site overlies alluvial fan deposits of the Kern River (Figure 3). Sediments underlying the region consist of fluvial deposits including silt, sand and gravel. Sediments encountered during drilling and excavation activities at the site consist primarily of well-sorted fine- to coarse-grained sand. A clayey sand layer, documented during previous investigations, is present locally from 2 to 3 feet below grade. An unconfined aquifer is present below the study area, the top of which is reported to occur at a depth of approximately 17~0_ fee~t (Figure 4). The gradient of this aquifer is generally toward the east-southeast (Figure 5). Shallow, perched water has not been identified in the vicinity of the site (Kern County Water Agency, 1990). SITE ASSESSMENT DRILLING PROCEDURES On May 30, 1991, Groundwater Technology drilled two borings at the locations shown on Figure 2. The borings were drilled to further define the vertical and horizontal extent of contamination. Borings B5 and B6 were drilled to total depths of 35 feet and 56 feet, respectively. Lithologic logs of the borings are presented in Appendix A. Boring B5 was back-filled with 5-sack cement/sand slurry upon completion of work. Boring B6 caved to within 2 feet of the surface during removal of the augers and therefore was not entirely Character i zat i on Report ARCO Products Cenpany June 25, 1991 2 I~ G~OUNDWAT~. ~ ~ECHHOLOGY back-filled with slurry. The upper two feet of the boring was f'flled with 5-sack cement/sand slurry and capped with concrete. Soil samples were collected at 5-foot depth increments using a split-spoon sampler lined with pre-cleaned, brass sample rings. The material from one sample ring was described on the lithologic log of the boring and field screened with a photoionization detector (PID) for volatile organic content. A second ring was sealed at each end with a teflon sheet, plastic cap, and tape. The samples were then sealed in waterproof bags and placed on ice pending submittal to an analytical laboratory. Between sampling events, the sampling equipment was washed with non-phosphate detergent and rinsed successively with tap and distilled water. Drill cuttings from the borings and water generated by steam cleaning the augers between borings and following the drilling operations were stored on site in 55-gallon drums. A sample of the water and two composite samples of the stored soil were submitted to a laboratory for chemical analysis. Laboratory analytical data indicated no detectable amounts of hydrocarbons in either the stored soil or water. Following verbal authorization by KCEHS the water was poured into a municipal storm drain and the soil was transported to an ARCO-owned property on Brundage Lane and spread on the ground. ANALYTICAL RESULTS The water sample, the two composite drill-cutting samples, two samples from boring B5 and all of the samples from boring B6 were sent by overnight courier to GTEL Environmental Laboratories in Torrance, California (Cert.#723), following standard chain-of-custody protocol. All samples submitted to the laboratory were analyzed for TPHG and BTEX using EPA methods 8015 and 8020, respectively. Neither TPHG nor benzene concentrations exceeded method detection limits in any of the soil or water samples. Minor concentrations of toluene, ethylbenzene, and xylenes are present in some of the soil samples from the borings at depths of 30 to 40 feet. Character i zat i on Report ARCO Products Company June 25, 1991 3 TECHNOLOGY Based on the analytical results of samples collected during tank removal operations and this assessment it is estimated that less than 100 yd3s of soil bearing greater than 1,000 mg/kg TPHG exists in the subsurface at the site. Presented on Figures 6 and 7 are approximate contours of the hydrocarbon plume which contains greater than 1,000 mg/kg TPHG. Laboratory results are presented in Table 1. Laboratory reports and chain-of-custody documentation are presented in Appendix B. FEASIBILITY STUDY Three remedial action options have been considered for this site. excavation, and soil venting. They include no action, NO ACTION The no action alternative would involve maintaining the asphalt/concrete cap overlying the areas impacted with hydrocarbons. No further action would be undertaken to mitigate soil contamination. The asphalt/concrete cap will prevent human contact with the hydrocarbons and prevent infiltration of rainwater. With no further addition of hydrocarbons to the plume, natural degradation will eventually eliminate soil impaction. This option would require no implementation costs and there would be no associated worker health and safety risks. EXCAVATION Excavation would involve destruction of large portions of the asphalt and concrete slabs which overlie the plume and the removal of impacted soil. The excavated soil wOuld be disposed of in a Class II landfill. The total volume of impacted soil is estimated to be less than 100 yds3. The estimated time to complete this option would be approximately two weeks, and costs could range from $75,000 to $125,000. Possible health and safety risks associated with this option include worker and public exposure to impacted soil, the volatilization of hydrocarbons during excavation activities, and the dangers inherent in heavy equipment operation. Surface structures at the site may also be damaged by excavation operations. Characterization Report ARCO Products Company June 25, 1~1 4 · I~-~ GROUNDWATER ~ ~ECHNOLOGY Table 1.

The contaminated vapor stream would be treated with abatement equipment to remove VOC's prior to venting to the atmosphere under an APCD permit. Necessary equipment would include a vapor extraction point(s), an explosion-proof regenerative blower, vapor-abatement equipment (cat-ox, therm-ox, or IC engine) and associated plumbing. The estimated time to complete this option would be one year, and costs would range from approximately $60,000 to $90,000. Health and safety risks associated with this option are the dangers inherent in heavy equipment operation and the possible creation of explosive atmospheres. Characterization Report ARCO Products Company June 25, 1991 5 [][][]C.OVNOWATE. TECHNOLOGY REMEDIAL ACTION PLAN The preferred remedial action plan at this site is no action.. Based on results of.samples collected during tank removal it is estimated that less than 100 yds3 of'soil bearing greater than 1,000 mg/kg TPHG remains in the subsurface at the site. New double-walled storage tanks have been installed at the facility thus eliminating the source of contamination in the area of the former tank pit. The buffer zone between impacted soil and groundwater is. approximately 145 feet. Also, the~analytical data generated by this assessment su~,.j~ests that a limited amount of degradation of the hydrocarbon plume has already occurred since the initial assessment in March, 1987. Therefore, it is unlikely that the remaining impacted soil would pose a threat to humans, other bioreceptors, or groundwater if the concrete/asphalt paving is maintained and natural degradation is allowed to occur. In the event that the County requires active remediation at the site, soil venting would be an alternative remediation method. Soil venting is a proven technology which will remediate the plume in a shorter time frame than natural degradation, however, costs are higher. The excavation alternative is not considered feasible due to high costs, worker safety concerns, and possible damage to surface structures. If necessary, a complete remedial action plan will be developed upon final selection of a remedial alternative.
