The remedial work was performed by Kern Environmental Services in accordance with. the Remedial Action Plan (RAP) dated March 19, 1991. After it was determined by visual methods that the affected soils had been removed, cleanup confirmation soil samples were obtained by Twining at the direction of Mr. Joe Canas of the Kern County Environmental Health Services Department (KCE~iSD). The soil samples were obtained from the bottom of the excavation and from each sidewall of the excavation. In addition, two soil samples were obtained from the former UST piping trench. The confirmation soil samples were analyzed by Twining for Oil and Grease and Lead. The analytical results of the soil sample analyses are presented in Table No. 1.

The KCEHSD concluded that the potential existed for soil samples S-22 and S-24 to contain concentratiOns of soluble lead in excess of the regulatory limit of 5.0 milligrams per liter (mg/1) set forth in Title 22, Article 11, Section 66699, California Code of Regulations (Title 22 CCR). The KCEHSD requested that the soluble lead concentration be determined for these samples by the Waste Extraction Test (WET) method described in Title 22 CCR. A WET was performed 'on the samples by Twining on April 3, 1991. The analytical results of the soil sample analyses are presented in Table No. 2.

The soil sample was obtained from the on-site soils at a location approximately 10CI feet northwest from the former UST location at a depth of approx~aately 3 feet BSG. The soil sample was analyzed for oil and grease constituents by Zalco Laboratories Fresno Modesto Visalia Bakersfield TL 988-099-07 Page 6 in Bakersfield, California on April 11, 1991. The analytical result of the'soil sample analysis is presented in Table No. 3.

Fresno Modesto Visalia Bakersfield TL 988-099-07 Page 7 After the confirmation soil samples were obtained from the excavation, the excavation was backfilled with imported fill material. The excavation was closed at the request of the city of Bakersfield Department of Public Works and the KCEHSD because of the close proximity of the excavation to the alley located east of the excavation. The fill was compacted to a minimum of 90 per cent of the - maximum density of the fill material. The backfilling operation was monitored by Twining personnel and in-place density tests were taken during the fill placement in accordance with ASTM Method D-2922. 3.0 EVALUATION The analytical results of the soil samples analyses indicate that the oil and grease concentrations detected in the confirmation samples are. within the range of the proposed cleanup level of 50 mg/kg recommended in the RAP witlh the exception of soil sample S-24 (east sidewall location). Howew~r, the detected level of 105 mg/kg in soil sample S-24 falls within the background range of 10 mg/kg to 130 mg/kg which was established for the on-site soils by laboratory analyses during the remedial and subsequent phases of the investigation. The analytical results of the soil sample analyses for the samples obtained by B.C. Laboratories at the time of the UST removal Fresno Modesto Visatia Bakersfield TL 988-099-07 Page 8 in February 19'88 indicated that the soils beneath the piping contained a concentration of 1,428 mg/kg oil and grease at a depth of six feet below the piping. However, when excavating the contaminated soil from beneath the former piping during the remedial work, visual observations by Twining personnel and the results of the confirmation sample analyses indicated that the extent of the contamination beneath the piping did not exceed a depth of three feet BSG. A possible explanation for this discrepancy may be that the soil sample obtained by B.C. Labs could have been taken at a location within the westward lateral extent of the soil contamination resultin~ from the leaking UST and not beneath the piping. Furthermore, the piping was not removed at the time that the UST was removed in February 1988. but was removed by Kern Environmental Services during the remedial work, thus, it would appear unlikely that B.C. Labs could have obtained a soil sample at a depth of six feet beneath the piping. During the remedial work, the soil in the vicinity of the former UST was .excavated to a depth of approximately 11.5 feet BSG for a distance extending in the direction of the piping for approximately eight, feet, thus, it may be concluded that if any contaminated soil did exist at a depth of six feet beneath the piping, it existed within the lateral extent of the contamination resulting from the former UST and that it was removed as part of the remedial work. Fresno Modesto Visalia Bakersfield STL 988-099-07 Page 9 The analytical results of the soil sample analyses for total lead and soluble lead for all of the confirmation soil samples are below the TTLC of 1,000 mg/kg and the STLC of 5.0 mg/1 set forth'in Title 22 CCR, 4.0 CONCLUSION Based on the field observations and the analytical results of the .confirmation soil sample analyses, the contaminated soils resulting from the former UST have been removed and disposed of in accordance with state and federal regulations. 5.0.

(Twining) has prepared this letter to request closure for the former waste oil UST located at the above referenced address. A summary of the remedial activities and the analytical results of the soil sampl'e analyses of the cleanup confirmation samples is presented for review by your department. 'On March 25, 1991 approximately 56 tons of soil containing oil and grease were excavated from the location of the former UST and the UST piping trench at the project site. The remedial work was performed by Kern Environmental Services under the direction of Mr. Bruce BlYthe of Twining. After it was determined by visual methods that the entire portion of affected soil had been removed, cleanup confirmation soil samples were obtained by Twining under the oversight of your department. The soils samples were taken from the bOttom of the excavation and from each sidewall of the excavation. In addition, two soil samples were obtained from the soils beneath the former UST piping run. The confirmation soil samples were analyzed by Twining for Oil and GreaSe and Lead (TTLC). The analytical results of the soil sample analyses is presented in Table No. 1. The laboratory and chain of custody documentation is attached.

Twining's Remedial Action Plan with Fresno Modesto Visalia Bakersfield t~e exception of soil sample S-24 (east sidewall). Although soil sample S-24 exceeded the cleanup level by approximately 50 ppm, it is Twining's opinion that this level is acceptable. The results of the soil sample analyses for total lead were well below the maximum TTLC level of 1,000 mg/kg set forth in Title 22, California Code of Regulations. On March 26, 1991 the excavated soil was transported as manifested .hazardous waste by Kern Environmental Services to the Class I Waste Management Unit operated by Chemical Waste Management, Inc. located near Kettleman City, California. Prior to accepting the soil for disposal, the soil was profiled by Chemical Waste Management under Waste Profile Number AL 7949. Copies of the waste profile documentation and the hazardous waste manifests are attached. After the confirmation soil samples were obtained from the excavation, the excavation was backfilled with imported fill material° The fill was compacted to a minimum of 90 per cent of the maximum density of the fill material.~ The backfilling operation was monitored by Twining personnel and nuclear density tests were taken periodically during the fill placement. Copies of the nuclear density test results are attached. Based on our field observations and the analytical results of the confirmation soil samples obtained, Twining believes that this site has been adequately remediated and will not pose a threat to the environment, the public health and safety, or the future development of the property. Twining requests on behalf of Mr. Bailey that your department grant clean closure status to this site. Please be advised that due to a pending real estate transaction a prompt response from your department will be appreciated. On behalf of Mr. BaileY, Twining thanks you for your cooperation and patience during the course of this project and we look forward to working with you on others.

The site is rectangular in shape and measures approximately 800 feet by. 300 feet in plan dimension. The site is bound on the north by 24th Street, on'the south by 23rd Street, on the east by Eye Street, and on the west by "H" Street. A project location map is presented on Drawing No. 1. The site is occupied by the former Valley Oldsmobile facility which consists of a vacant automobile sales lot, a vacant automobile repair shop, a vacant automobile showroom and business offices. The approximately 40 year old, 550-gallon UST was located in the central portion of the property, adjacent to the northeast corner of the automobile showroom. A site plan depicting these features and the former UST.location is presented on Drawing No. 2. 2.2 Regional Geology: Bakersfield is located within the southern San Joaquin Valley Region of the Great Valley (valley) Geomorphic Province of California. Surficial deposits in the Bakersfield area occur as Quaternary Age alluvium derived from the Sierra Nevada which borders the eastern boundary of the valley. 0 Fresno Modesto Visalia Bakersfield KERN COUNTY ^mi'OaT NO. ~ ~LIVE DR.

The foregoing is a general summary of the subsurface conditions encountered in the soil borings drilled for this study. Detailed descriptions of the soil conditions encountered in the borings are presented on the boring logs in Appendix A. The stratification lines shown on the boring logs represent the approximate boundaries between soil types; the actual in-situ transitions may be gradual. 2.3 Regional Hydroloqy: First encountered groundwater in-the Bakersfield area occurs predominantly in unconfined (water table) conditions within the unconsolidated alluvium' Depth to groundwater in September 1989 was approximately 165 feet BSG according to information provided by the California Water Service Company of Bakersfield. The regional direction of groundwater flow is northeast. No perched water tables are known to exist beneath the property. Depth t~ groundwater and shallow groundwater direction of flow, gradient, and velocity can be affected by groundwater production well pumping, seasonal recharge, and other variables in the vicinity of the property. Fresno Modeslo Visalia Bakersfield TL'988-099-03 Page 4 2.4 Project History: A closure plan was submitted to the Kern dounty Department of Environmental Health Services (KCDEHS) by Valley Oldsmobile in October 1987 and the UST and piping were removed by McNabb Construction Company on February 9, 1988. At the time of the UST removal, two soil samples were obtained by B.C. Laboratories in Bakersfield, California from beneath the UST at depths of two feet and six feet below the bottom of the UST. The piping extended for a distance of approximately 30 feet west of the UST; two additional soil samples were obtained at depths of two feet and six feet below the bOttom of the piping. The.soil samples were analyzed by B.C. Laboratories for total lead, oil and grease, and total halogenated hydrocarbons. The analytical results of the soil sample analyses are summarized in Table No. 1.

Based upon the analytical .results of the soil sample analyses, the KCDEHS requested that a RI be conducted to assess the vertical and horizontal extent of petroleum product migration in the soils beneath the UST. .Twining was retained by Isaacs and Bailey and an RI Work Plan was prepared. The work plan was approved by Mr. Bill Scheide of the KCDEHS by telephone on October 25, 1988. An RI was 'conducted by Twining in October 1988. 2.5 Summary of Remedial Investigation: The following subsections provide a brief sun~ary of the Remedial Investigation report, dated March 6, 1990 (TL 988-099-02). Fresno Modeslo Visalia Bakersfield' 988-099-03 Page 6 2.5.1 Field and Laboratory Investigation: To determine the extent of petroleum product migration, four soil borings were drilled in the immediate vicinity of the UST. The soil boring locations are shown on Drawing No. 3. The soil borings were drilled to a maximum depth of 26.5 feet BSG. To access the extent of potential petroleum product migration beneath the automobile showroom located adjacent to th,s UST, soil boring B-3 was slant drilled at a 30° angle beneath the structure to a vertical depth of approximately 22 feet BSG. Soil samples were collected from each boring at depths of 5, 10, 15, 20 and 25 feet 'BSG. The soil samples were analyzed for oil and grease (U.S. EPA method 413.1) and total lead. 2.5.2 Results of Soil Samples Analyses: The analytical results of the. soil samples obtained from the exploratory soil borings are presented in Tables No. 2 and No. 3.

In light of this condition, the RI report recommended that additional soil sampling and laboratory analyses be conducted to determine the soluble concentration of lead by the waste extraction test (WET) method. Soil samples were obtained by Twining on December 19, 1990 from the approximate location of soil boring B-3 (at the approximate location of the UST) at depths of 2.5 feet and 8.5 feet BSG. The soil samples were analyzed by Zalco Laboratories for Oil and Grease, Soluble Metals (STLC), and for Hazardous Waste Criteria (Ignitability, Reactivity and Corrosivity) Title 22, California Code of Regulations (C.C.R.), Sections 66702, 66705 and 66708.

To confirm the results of the December 19, 1990 sampling event, Twining returned to the property on January 14, 1991 and. obtained an additional soil sample from the approximate location of SoiI Boring No. 3 at a depth of 2.5 to 3.0 feet BSG. The soil sample was analyzed for soluble lead by Fresno Modesto Visalia Bakersfield TL 988-099-03 Page 12 Twining's analytical chemistry laboratory located in Fresno.

Based on those findings it was estimated that the horizontal extent of oil and grease migration and possibly lead is in an area centered on the UST location with a radius of apProximately six feet, assuming that the Fresno Modesto Visalia Bakersfield TL 988-099-03 Page 13 Product migration has followed a symmetrical pattern. It was also determined that soils with elevated concentrations of oil and grease and' possibly lead extend vertically to a depth of approximately 11.5 BSG. The known extent of the soils containing elevated concentrations of oil and grease and lead are illustrated on Drawings No. 3 and No. 4. 2.8 Requlatory considerations: The laboratory analyses conducted on the soil samples for the RI and for the December 1990 and January 1991 sampling events indicate that soils in the vicinity of the UST contain concentrations of oil and grease constituents ranging from nondetectable (ND) to 74,000 mg/kg. In addition, the soils contain concentrations of total lead rangin~ from 3 to 590 mg/kg, and soluble lead ranging from 30 to 75 mg/1. Currently no regulatory guidelines have been established by the U.S. Environmental Protection Agency (U.S. EPA), the California Regional Water Quality Control Board (RWQCB), or the KCDEHS for allowable levels of. oil and grease that may ibe left in place within the vadose zone California regulations for hazardous waste criteria, 22 Cal. Adm. Code 66699, states that a waste is hazardous if the soluble concentration for lead and lead compounds exceeds a concentration of 5.0 mg/1. Based on the analytical results of the soil sample analyses, all or a portion of tire affected soils are considered hazardous and ~equire remediation.

TL 988-099-03 Page 14 2.9 Potential Environmental[ Effects: The soils containing elevated concentrations of oil and grease and lead are separated from groundwater by approximately 150 feet. The average, annual rainfall in the Bakersfield area is approximately six inches. No perched groundwater conditions were encountered during the RI to a depth of 26.5 feet BSG, the maximum depth explored. The ground surface in the vicinity of the-UST has been paved with asphaltic concrete during the time period that the UST was maintained on the property, thereby decreasing the potential for migration which could be promoted by percolation of surface waters through the vadose zone. In addition, oil and grease constituents and lead compounds do not readily migrate in soil; thus, the potential for petroleum products to leach thbough the vadose zone and impact the groundwater beneath the property appears to be low. The analytical results of the soil sample analyses indicate that the affected soils at the site contain hazardous concentrations of lead. Because 'the site is located in a populated area and will probably be redeveloped for commercial use, the potential exists for the affected soils to present a health risk to individuals. This potential health risk 'is particularly high for workers and' others who may become exposed to the soils during demolition, and new construction'activities. It should also be noted that the existing contaminated soils, if left in place, may pose a Fresno Modesto Visatia Bakersfield TL 988-099-03 Page 15 liability to the site, i.e. marketability and market value. In additions, the contaminated soils, if not removed, could result in restrictions on future uses of the property. In light of the regulatory requirements, the potential environmental'effects, and the potential economical effects on the property; Isaacs and Bailey has chosen to remediate the soils containing concentrations of oil and grease and lead to acceptable regulatory levels. 3.0 REMEDIAL ACTION PARAMETERS This section summarizes the site features, the estimated extent and volume of the soils requiring mitigation, and the feasibility of selected remedial action alternatives that could be used at the site. 3.1 Site Features: The following conditions were~ observed during the investigation. o A portion of the soils requiring remediation may exist within the city of Bakersfield right-of-Way which is defined' as a distance of 12.5 feet outwardly from the centerline of the alley located east of the UST location. ~ o A 6-inch diameter city sewer line and a California Water Service Company distribution line are 'located beneath the centerline of t.he alley. · Fresno Modesto Visal,a Bakersfield TL 988-099-03 Page 16 Oil and grease is beliew~d to have migrated beneath the northeast corner of the showroom building located west of the al. ley and south of the UST location. 3.2 Extent of Soils Requirinq Remediation: The approximate horizontal extent of soils requiring remediation appears to be located within a 6-foot radius centered on the location of soil boring B-3. It should also be noted that the soils requiring remediation may extend laterally for a distance ~of approximately two to three feet beneath the Showroom building. The vertical extent of the soils reqUiring remediation is believed to be limited to a depth of about 11.5 feet BSG. The extent of the soils requiring remediation at the prope:uty is illustrated on Drawings No. 5 ~nd No. 6. Based on the estimated horizontal and vertical extent of affected soils in the vicinity of the UST, it is estimated that approximately 50 cubic yards of soil (75 tons) will require remediation. The extent of the soils containing oil and grease beneath the piping of the UST has not been determined, however it may be assumed, based on .the laboratory results of the soil samples obtained at the time of the piping removal, that an additional 20 to 30 cubic yards of soil may 'also require remediati~n. Thus, the estimated volume of soil requiring remediation could be aboUt 80 cubic yards (120 tons). Fresno Modesto ' Visalia Bakersfield X X X i---I it.

Information summarizing the potential remedial action alternatives is presented in the fOllowing subsections. The estimated costs presented herein are based on available bid tabulations, industry estimating manuals, and other available information. The cost estimates presented are preliminary only and the actual costs to remediate the site may vary substantially. If the accuracy level is not appropriate for' the purpose intended it is recommended that a formal bidding process be conducted prior to selecting a remedial action method. The remedial action alternatives are: o No-action; o Bioremediation; and o Excavation and Disposal. 3.3.1 No-action: The no-action remedial action alternative Would involve leaving in-place up to 80' cubic yards of soils containing elevated concentrations of oil and grease constituents and hazardous concentrations of lead. The no-action alternative would be the least costly, method of those evaluated, however, considering the previously discussed regulatory, marketing, and environmental concerns, the potential risks to the public Fresno Modesto Visafia Bakersfield TL 988-099-03 Page 18 health, and the potential impacts to the subject property, the no- action alternative is not considered feasible for this site. 3.3.2 Bioremediation: The bioremediation remedial action alternative would involve, excavating the affected soils and introducing naturally occurring and laboratory-mutated m'~ croorganisms into the soil which destroy organic wastes by secreting naturally occurring enzymes that break the chemical bond of organic compounds and absorb the matter within their cell membranes. Bioremediation could be a feasible alternative to remediate the oil and grease constituents which, exist in the soils. · However, because some or all of the soils contain relatively high concentrations of lead, and because lead compounds are toxic to the microorganism cultures used in the process, bioremediation methods could be utilized to remediate only a portion of the soils at the site. The estimated cost to bioremediate the soils at the site containing oil and grease constituents is approximately $190 'per ton. Assuming a quantity of 120 tons to be remediated, the estimated cost to remediate this portion of the soils would be approximately $22,800. To effectively remediate the soils using bioremediation methods the soils would have to be excavated and stockpiled on the property Fresno Modesto Visalia Bakersfield TL 988-099-03 ' Page 19 while the remedial process is being conducted and the soils containing concentrations of lead which could not be mitigated using bioremediation methods would require disposal at an off-site facility. Prior to commencing bioremedial operations, a feasibility and treatability study would be necessary to adequately characterize the waste and to determine which microorganism cultures Would be best suited for treatment. In light of the relatively small quantity of'soil' requiring remediation, the concentrations of lead, the relatively high unit cost per ton of soil treated, and finally because the method could not be utilized to treat the entire quantity of soils requiring remediation, bioremediation is not considered a cost effective and technically feasible alternative to remediate the soils at the site. 3.3.3 Excavation and Disposal: The excavation and disposal remedial action alternative involves removing the soils containing concentrations of oil and grease and lead and transporting the soil to an .approved Waste Management.Unit (WMU) for treatment and disposal. Because it has been determined that all or a portion of the affected soils contain high .concentrations of' lead and are hazardous, the selection of a suitable 'WMU is limited. Soils containing hazardous concentrations of lead can be accepted at the Chemical Waste Management, Inc..(CWM) disposal facility located near Fresno Modesto Visalia Bakersfield TL 988-099-03 Page 20 Kettleman City, California. Advantages of the excavation and disposal alternative include mitigating any potential threat,s to the public health and the environment that may exist as a result of the existing hazardous conditions at the site. In addition, by removing the affected soils from the site, clean closure can usually be obtained, thereby reducing the potential for future economic impact to the property concerning marketability and future development. A cost estimate to .remediate soils containing oil and grease, and lead at the site by excavation 'and disposal methods was prepared. The cost estimate was based on bids obtained from f contractors 'to excavate and transport 120 tons of soil to CWM for disposal. The cost estimate is presented in Table No. 6. It should be noted that the cost estimate is based on an assumption that 120 tons of soil will require remediation. The quantity of soil is an approximation only and the' actual quantity will not be known until the soils are excavated and characterized.

The remedial action plan for the excavation and disposal alternative is summarized in the following subsections. 4.1 Proposed Clean-up Levels: Because no regulatory limits have been established for acceptable concentrations of oil and grease constituents that may be left in place within the vadose zone, Twining proposes that a concentration of 50 mg/kg for oil and grease be used as the target ~clean up level for the site. In addition, soils with lead exceeding a total concentration of 1,000 mg/kg and a soluble concentration of 5 mg/1 will be removed. 4.2 Excavation: Following approval of this remedial action work plan by the KCDEHS, Isaacs and Bailey will contract with a licensed contractor to perform the work .in accordance with this plan. Prior to beginning the work, an excavation permit will be obtained from the city of Bakersfield Department of Public Works. In addition, because it is anticipated that the excavation will exCeed five feet in depth, an excavation and trenching permit should be obtained from Cal OSHA, also Underground Service Alert (U.S.A.) will be notified at least 48 hours prior to beginning excavation to Fresno Modesto Visalia Bakersfield TL 988-099-03 Page 23 verify the depths and locations of the underground utilities located in the vicinity of the proposed excavation. It will be the contractor's responsibility to obtain the necessary permits and to notify U.S.'A. prior to beginning work. After addressing the above requirements, the selected contractor will excavate the soils at the site using a backhoe. Care should be taken while excavating beneath the showroom building to avoid damage to the structure. It may be necessary to shore beneath the building during the excavation activity to prevent collapse and ensure worker safety. The excavated soils will be transported to CWM. Upon completion of the excavation operations, the excavation will be backfilled as engineered fill with imported clean soil. The backfilling operation will be monitored by Twining and-in-place density tests will be conducted as per Uniform Building Code and city of Bakersfield Public Works Department requirements. Fresno Modesto Visalia Bakersfield TL 988-099-03 Page 24 4.3 Confirmation Samplinq: Upon completion of the excavation phase and prior to backfilling the excavation, confirmation soil samples will be taken from the each sidewall and from the bottom of the excavation. obtained from the bottom of the approximately 15 foot intervals. Soil samples will also be excavated piping area at The soil samples will be transported to Twining's analytical chemistry laboratory in FreSno and analyzed for oil and grease and total lead. 4.4 Transportation and Disposal to WMU: The excavated soil will be transported by a licensed hazardous materials hauler to CWM. Prior to transporting the soil, the load will be manifested as hazardous waste and a Generator USEPA ID number will be assigned by the EPA. In addition, all waste profile docUmentation and credit applications for disposal fees will be completed and approved by CWM prior to transporting the soil. 4.5 Closure: After completion of the work and the results of the laboratory analyses of the confirmation soil samples are available,- a report documenting the work and the results of the laboratory analyses of the soils samples demonstrating that the approved cleanup levels have been achieved will be prepared and submitted to the KCDEHS with a request for clean site closure. Fresno Modesto Visalia Bakersfield TL 988-099-03 Page 25 5.0 HEALTH AND SAFETY PLAN A health and safety plan which addresses the safety provisions that will be employed during the remedial work is summarized in the following subsections. 5.1 Introduction: The objective of the plan is to describe the procedures and .actions necessary to protect the on-site personnel and other individuals from direct dermal contact, inhalation, and ingestion of potentially hazardous materials that may' be encountered during the remedial operations. 5.2 Project Safety. AuthorJ. ty: It is anticipated that the project safety officer will be Mr. Noah Beeber of Kern Environmental Services. Mr. Beeber will be the on-site supervisor and will be responsible for the enforcement'of the provision of this health and safety plan. 5.3 Job Hazard Analysis: The 'following subsections describe the chemical and physical haZards that may be encountered during the remedial work. 5.3.1 Chemical Hazards: The possible contaminants that may be .encountered on the project are Volatile Organic Compounds (V0Cs) and hazardous concentrations of Lead. There is currently no known air concentration data available for VOC emissions in the direct breathing zone for personnel working around the exposed soils. Fresno Modesto Visalia Bakersfield TL 988-099-03 Page 26 Inhalation and dermal (absorption) hazards are the major area of concern regarding exposure to VOCs. Results of toxicolOgical studies on animal exposure to pure concentrations of VOCs that may be encountered at the site are detailed in "Handbook of Toxic and Hazardous Chemicals", by M. Sittig (1981), and "Dangerous properties of Industrial Materials", by N. Irving Sax (1989-). An additional reference source used for the. development of this Health and Safety Plan is the "Documentation of the Threshold Limit Values (TLV)", published by the American Conference of Governmental Industrial Hygienists (ACGIH), Inc. Benzene: Benzene is a common constituent of gasoline and other petroleum product materials. It is a clear, colorless liquid, with a flash point of 12°F. The current listed TLV for Benzene is 10 ppm in air, however, the ACGIH has recommended a TLV of 1 ppm be adapted. Toluene: Toluene is a flammable, colorless, liquid with a benzol-like odor. The flash point for Toluene is 40°F. The currently established TLV for Toluene is 100 ppm in air. Xvlene: Xylene is a clear ]Liquid with a flash point of 100°F. The current TLV for Xylene is 100 ppm in air. Xylene is currently being evaluated as a possible carcinogen. Lead (inorganic): Inorganic Lead is a bluish-grey, soft metal. Inorganic lead presents its greatest health risk when found in the Fresno Modesto Visatia Bakersfield TL 988-099-03 Page 27 form of lead fumes. Lead fumes are usually generated by decomposition at high temperatures. Inorganic lead is classified as a Poison "B" by the U.S. Department of Transportation (D.O.T.). The vapor pressure of inorganic lead is 1 mm at 973°F, thi~ would indicate that lead vapor is not; a health risk for this project, however, exposure to dust containing inorganic lead should be considered hazardous. Lead (organic): Organic Lead or Tetraethyl Lead (TEL) is also a health hazard for. exposures to airborne vapors and -fumes. However, like inorganic lead, vapors of TEL generally require accelerated temperature increases to release vapors of significant volume. The vapor pressure for TEL is 1 mm at 38.4°F and the flash point is 200°F. The primary Route of Entry (ROE) for TEL is by skin absorption. Upon exposure to sunlight, TEL decomposes to Triethyl Lead and Tetramethyl Lead. Both of these compounds have similar physical characteristics and ROE as TEL. 5.3.2 Physical Hazards: The primary physical hazards and conditions that can be anticipated during the project include heavy equipment operations, slope stability during excavation, and possibly confined space entry. In addition, the foundation stability of the building located adjacent to the work area may represent a potential.physical hazard during the excavation phase Of Fresno Modesto Visalia BakersfieLd TL 988-099-03 Page 28 the remedial work. Care should be taken to ensure that personnel in the work area remain out of the swing radius area of the backhoe or excavator. Hearing protection should be worn by all personnel in the vicinity of operating equipment. The sides of the' excavation should be cut to be no steeper than 1 to 1, horizontal to vertical, if the excavation exceeds 5 feet in depth. Personnel should avoid entering the excavation if possible. In the event that it is necessary to enter the excavation for any reason, Confined Space Entry rules and procedures must be followed. While excavating the soils from'beneath the building'the soil and foundation stability should be monitored to ensure worker safety and to avoid damage to the structure. If it is determined that unstable soil and foundation conditions exist then the building should be adequately shored to prevent collapse. 5.4 Risk Assessment Summary~: It is not anticipated that there will be any significant exposures of VOCs and lead to other individuals, the environment,, or to the public in the vicinity of the project site, therefore, the potential for risk of exposure t° others is considered minimal. However, the potenfial may exist for exposure to others of airborne dust and soil that may contain levels of VOCs and lead during, the excavation and stockpiling phases of work. To minimize the potential of airborne contaminants it is Fresno Modesto Visal~a Baker slield ~L 988-099-03 Page 29 recommended that dust control procedures be utilized if deemed necessary by the project safety officer. 5.5 Personal Protective Equipment: It is important that adequate personal protective equipment and clothing be worn by personnel working in the immediate work area. All field personnel and visitors to the project site during work operations will be required to wear: o Hard Hats; o Safety Glasses; and o Long Sleeved Shirts. In addition to the above requirements it will be necessary for workers on the site, that may be exposed to the potential contaminants previously identified, to be provided with and wear Level "C"' protective clothing and respiratory 'devices if deemed necessary by the project safety officer. Level "C" protection will include: o o o o o Saranex Tyvec Suits; Nitrile Outer Gloves; Latex Or Vinyl Inner Gloves; Rubber Boots; and Half-face or Full-face Respirators Equipped with Organic Vapor and Dust Pre-Filter Cartridges. Fresno Modesto Visatia Bakersfield TL 988-099-03 Page 30 Personal protection clothing and equipment shall be worn by all personnel who enter the designated work area. The sleeves of the coveralls will be worn outside of the glove gauntlets to facilitate removal of the clothing and to minimize the potential for dermal contact of hazardous materials. If at any time during the work operations, the protectiwa clothing becomes torn, wet, or excessively soiled, it shall be replaced. 5.6 Work Zone and Security: Prior to commencing work, the work area will be designated by safety tape, barriers, or other acceptable means by which unauthorized personnel can be prevented from entering the work area. During the work process unauthorized personnel will not be permitted to enter into the designated work area. In the event that unauthorized individual(s) enter into the designated area then work will be immediately discontinued until such time as the unauthorized individual(s) is removed from the designated area. 5.7 Decontamination Protocol: Decontamination procedures are essential to prevent transporting potentially hazardOus materials from the site and to protect the health and safety of the personnel involved in the remedial work. At the end of the shift'or workday, the following steps will be taken to allow for the safe removal and disposal of the protective clothing and equipment used during the day. Fresno ' Modesto Visalia 8akerslield TL 988-099-03 Page 31 O Respirators will be washed with warm water and soap, allowed to air dry, and placed in a sealed plastic bag. Prior to next use, the organic vapor cartridges will be replaced. Rubber boots and gloves will be washed with warm water and soap, then rinsed prior to removal. Boots and coveralls will be removed and, if contaminated, placed into a drum designated for Proper disposal. Gloves will be removed and hands will be washed with warm water and soap. 5.8 General Safe Work Practices and Sanitation Requirements: Eating,. drinking, or smoking will not be allowed within the designated work area. ContaCt lenses should not be worn by personnel within the designated work area. 5.9 Emergency Procedures: Symptoms of direct exposure to significant concentrations of VOCs include: irritation of the eyes, nose and skin; vomiting; headache, dizziness and light,headedness; lack of coordination; nausea and unconsciousness. If any of the above symptoms develop, the following first aid procedures should be taken: o O O Skin: Remove contaminated clothing immediately. Flush affected area with water, then wash with warm water and soap. Eyes: Hold the eyelid open and flush with water. Lungs: Move to fresh air immediately; give artificial respiration and CPR if necessary.

Specifically, this letter discusses for each remedial action alternative: The short and long term effects of each remedial action alternative on the public health and'the environment. An estimated cost analysis for each alternative on a preliminary basis. The technical feasibility of each alternative and its applicability to the site. Finally, the letter presents to your department Twining's proposed remedial action alternative for the site based on the findings and conclusions of the RI report and from discussions held with you and Mr; Cecil Bailey, the Responsible Party (RP), regarding [] 2527 Fresno Street · P.O.

Briefly, the RI report: prepared for Isaacs and Bailey concluded that soils containing elevated concentrations of oil and grease constituents exist in the on-site soils beneath the former 550-gallon .underground waste oil tank to a depth of between 11.0 feet and 16.5 feet below site grade (BSG). The lateral extent of the zone of soils containing oil and grease constituents was estimated to be approximately 12 feet in diameter and centered on the former tank location.

The average annual rainfall in Bakersfield is approximately 6-inches per year. No man-'made conduits which could increase the potential for additional migration of the hydroqarbons were identified during the investigation and the site is paved with asphaltic-concrete. The RI report also concluded that a portion of the affected soils probably exists beneath the structure located adjacent to the former underground tank location. Fresno Modesto Visalia Bakersfield ~Kern County Dept. of Environmental Health October 18, 1990 Page 4 Because there are currently no local or state regulatory guidelines for maximum allowable concentrations for oil and grease that can be left in place within the vadose zone, it is necessary to evaluate the potential environmental effects of the existing on-site conditions as a specific case based on the site specific conditions. The following remedial action alternatives were presented in the RI report: 1. No action 2. Excavation and disposal at a "Class I" disposal unit 3. Bioremediation methods The remedial action alternatives are discussed in the following paragraphs. The no action remedial alternative would involve leaving in- place approximately 70 cubic yards of soils containing elevated concentrations of oil and grease constituents. Concentrations of oil and grease ranging from 33,000 ppm to 74,000 ppm exist in the on-site soils to a depth of approximately 12 feet BSG. The estimated vertical extent of the affected soils is separated from groundwater by approximately 125 feet. Because of its low viscosity and low volatility, oil and grease constituents do not readily migrate vertically in soil as do the lighter hydrocarbons. Therefore, it is unlikely that the oil and grease constituents would migrate through the vadose (unsaturated) zone and encounter Fresno Modesto Visalia Bakersfield Kern County Dept. of Environmental Health October 18, 1990 Page 5 groundwater. The source of the oil and grease is believed to be waste oil generated from the automobile service facility located on the site. California law currently classifies waste oil as a hazardous substance under the Hazardous Waste Control Law (Health and Safety Code Section 25100). Because the site is located in a populated area the potential exists fc.r the soils to present a health and safety hazard. In addition, the site may be redeveloped in the future, increasing the potential for workers and others to be exposed to the soils during demolition and construction activities. The no action alternative may also pose a potential concern to the site with respect to the ~future marketability of the property because this alternative would not result in a clean closure. Twining's conversations with Kern County Environmental Health Department (KCEHD) and the Regional Water Quality Control Board representatives have concluded that because of the relatively high concentrations of oil and grease that exist in the on-site soils it may be advisable to remediate the site and attempt to obtain a clean closure. The costs associated with the no action alternative would be limited to the expense of disPosing of the drill cuttings currently stored on the site and for repaving the area of the lateral extent of the affected area with an impermeable layer to further reduce the Fresno Modesto Visalia Bakersfield Kern County Dept. of ~Environmental Health October 18, 1990 Page 6 potential for migration of tlhe hydrocarbons and to protect the · public from possible exposure to the soils. Based on the relatively high concentrations of oil and grease, the potential for threat to the public health, the potential for future impact on the property, and the unlikelihood for gaining regulatory approval, the no action alternative does not appear feasible for the site. The excavation and disposal remedial action alternative involves physically removing the soils containing elevated concentrations of oil and grease from the site and transporting them to a Class I (Hazardous Waste) disposal facility. It is estimated that approximately 105 tons of soil would require excavation and disposal to achieve this.. Advantages of the excavation and disposal alternative include mitigating any potential threats to the public health and the environment that may exist as a result of the on-site conditions and also obtaining a clean closure for the site, thereby, eliminating the possibility of any future economic concerns to the site and the property owner. Prior to being accepted at a Class I disposal site, the affected soils would require laboratory analyses to classify the waste and determine its acceptability status. The classification of the waste would determine the cost for disposal. If it is Fresno Modesto Visalia Bakersfield 'Kern County Dept. of Environmental Health October 18, 1990 Page 7 determined that the soils contain hazardous concentrations of metals, then the cost of disposal will be approximately $110.00 per ton. If it is determined that the soil is not hazardous then the disposal cost would be substantially reduced to approximatelY $11.00 per ton. The disposal costs could range from approximately $1,155.00 to approximately $11,550.00 to adequately remediate the site. The other estimated costs associated with the excavation and disposal method .are presented below. PRELIMINARY COST ESTIMATE FOR THE EXCAVATION AND DISPOSAL REMEDIAL ACTION ALTERNATIVE Activity Cost Remedial Action Plan Permits Excavation Transportation (105 cubic yards) Waste Disposal Fees: ($770.00/$7,700.00 Non-hazardc. us/Hazardous) Backfill and Compaction Paving Chemistry Project Management $ 2,500.00 $ 200.00 $ 1,100.00 $ 1,200.00 $ 2,000.00 $ 1,100.00 $ 1,100.00 $ 1,000.00 Estimated Total : $ 10,200.00 Although the costs associated with this remedial alternative are greater than the no action alternative, they are probably less than for other methods of remediation that could be used to Fresno Modesto Visalia Bakersfield Kern County Dept. of Environmental Health October 18, 1990 Page 8 remediate the site. BaSed on the cost effectiveness in comparison with other methods which are discussed below; and the other advantages previously discussed, the excavation and disposal remedial action alternative is considered feasible for the site. The bioremediation remedial action alternative involves excavating the affected soils and introducing microorganisms into the soil which then attack and degrade hydrocarbons within a controlled environment. Advantages to this method are that it can eliminate the short and long term liabilities resulting from off- site transportation and disposal, it can achieve a clean closure, and it can be a cost effectiwe method for treating large quantities of soil. Disadvantages of the method include: lack of effectiveness in treating soils containing high concentrations of oil and grease, the methods do'not work on soils containing metals, the soil requires excavation, and the method is often not cost effective when treating relatively small quantities of soil. It is estimated that the costs required to bioremediate the soils at the site would be approximately $210,000 or a unit cost of approximately $190.00 per ton. Because of the relatively small quantity of soil involved, the high concentrations of oil and grease, the possibility that the soils may contain metals, and the relatively high unit cost per ton, Twining concludes that bioremediation is probably not a feasible alternative to remediate the site. Fresno Modesto Visalia ' Bakersfield Kern County Dept. of Environmental Health October 18, 1990 Page 9 Upon review of the feasibility of each remedial action alternative presented, Twining recommends that the soils containing elevated concentrations of oil and grease and possibly metals be remediated'by excavating and transporting them to a Class I disposal site. It is our opinion that this remedial alternative is a feasible, cost effective method that best serves the interest of the environment, the public heal~'h, and the client with respect to future environmental and economical liabilities which may result from the existing on-site conditions. If the proposed remedial action alternative is considered acceptable to the KCEHD it will be necessary to prepare a Remedial Action Plan and Health and Safety Plan for submittal to the KCEHD prior to implementing the proposed remedial action. The report will address the technical approaches that will be followed to adequately mitigate the on-site conditions and to dispose of the material generated by the remedial action.

BAKERSFIELD, CALIFORNIA OR~w~6 No. TL 988-099-02 Page 3 2.2 Reqional Geoloqical and Hydroloqical Characteristics: Bakersfield is located within the southern San Joaquin Valley Region of' the Great Valley (valley) Geomorphic Province of California. The ~valley is a nearly flat, northwest to southeast trending alluvial plain which is approximately 450 miles long and 50 miles wide. The valley extends from the granitic Sierra Nevada Range on the east to the metamorphic and sedimentary Coast Ranges on the west. The valley is bound on the north by %he Klamath Mountains and on the south by the Tehachapi Mountains. The valley is a geosyncline that has been filled with a seqUence of marine and continental sedimentary rocks of Tertiary and Quaternary age resting uncomformably on a basement complex of metamorphic and igneous rocks (Dibblee and Oakshot, 1953). 'The surficial Quaternary deposits in the Bakersfield area occur as alluvial deposits derived from the Sierra Nevada Range to the east. These deposits generally are oxidized, and on the upper parts of the larger fans, adjacent to the mountains, consist of moderately to highly permeable, yellowish brown gravels, sands and silts. On the lower parts of the fans, these deposits consist of poorly to moderately permeable, yellowish brown sands and silts. The Surficial geology of the subject property consists of alluvial Sands and silts (Wood and Dale, 1964). Groundwater in the Bakersfield area occurs within the Edison subarea of the Edison-Maricopa area. This subarea includes the Fresno Modesto Visalia Bakersfield ~TL 988-099-02 Page 4 urban and irrigated areas alon9 the southeastern border of the San Joaquin Valley between the Kern River and Caliente Creek. Part of its southern boundary is formed by a northwest trending groundwater barrier coinciding generally with the Edison Fault. Westward from the East Side Canal, three miles northwest of Edison, the subarea is bound on the south by an arbitrary line marking the approximate soUthern limit of the area in which appreciable quantities of water are obtained from the Kern River formation. Groundwater in the~ Edison subarea is used principally for the municipal and agricultural water supply in the Bakersfield urban area. Groundwater in the Bakersfield ~rea occurs predominantly in unconfined (water table) conditions in the unconsolidated alluvium. Depth to groundwater at the site is approximately 165 feet below site grade (BSG) according to information provided by the California Water Service Company for September .of 1989. The regional direction of groundwater flow is northeast. Groundwater recharge in the' Edison ~subarea is derived from surface waters from irrigated land to the West, from the Kern River to the north of the subarea, and from Caliente Creek on the east (Wood and Dale, 1964). 2.3 Pro~ect History: A 550 gallon underground waste oil storage tank was formerly located on the site. The 32 year old tank was removed from the site on February 9, 1988, by McNabb Construction Company. Four soil samples~were obtained by Mr. David Fresno Modesto Visal~a Bakersfield TL 988-099-02. Page Rittenhouse under the direction of the Kern County Environmental Health Department (KCEHD) at'the time the tank was removed~ Two soil samples were 'taken from below the invert level of the former tank' at depths of 2 feet and 6 feet. Two additional soil samples were taken at depths of 2 feeti and 6 feet below the piping which extended approximately 30 feet west of the tank. The soil samples were delivered to B.C. Laboratories in Bakersfield, California, where they were analyzed for lead~ oil and grease, and total halogenated hydrocarbons (TOX) as required b~ the Kern County Environmental Health Department (KCEHD). The analytical results of the s°il sample analyses are summarized in Table No. 1.

Based on the ab6ve findings, Mr. Bill Scheide of the KCEHD requested a remedial investigation (RI) work plan for assessing the extent of petroleum product migration beneath the former underground waste oil storage tank. An RI work plan was prepared by Twining at the request of Mr. Cecil Bailey. The RI work~ plan was subsequently approved by KCEHD Fresno Modesto Visalia Bakersfield TL 988-099-02 Page 7 via a telephone conversation on October 25, 1988, between Mr. Bill Scheide (KCEHD) and Mr. Theodore Wright (Twining). 3.0 PURPOSE AND SCOPE OF INVESTIGATION The purpose of the remedial investigation was to determine the vertical and lateral extent of petroleum product migration caused by leakage of the former underground waste oil storage tank. This work was conducted in accordance with Twining's RI work plan dated september 1, 1988. In addition, the data obtained were evaluated to assess the potential environmental effects of the petroleum product migration. Pinally, the need for additional studies and/or remedial actions were assessed. The actions taken to achieve the stated purpose are summarized as follows: 1. An RI work plan (dated September 1, 1988) was prepared and submitted to the KCEHD~ and subsequently approved by Mr. Bill Scheide of the KCEHD on October 25, 1989, with the following revisions: a) That lead and' cadmium analysis be performed on a portion of the soil samples taken. b) That TOX analysis would not be required for this investigation. Mr. Cecil Bailey with Isaacs and Bailey and Mr. Joe Canas with KCEHD were consulted during this investigation. Fresno Modesto Visalia Bakersfielcl TL 988-099-02 Page 8 Four exploratory soil borings were drilled approximate to the location of the former waste oil tank. The soil borings were drilled to a maximum depth of 26.5 feet BSG. Soil samples were collected at depths of 5, 10, 15, 20 and 25 feet BSG; in each soil boring. Soil samples were prepared for shipment to Twining's laboratory in Fresno for analysis. Soil samples from the soil borings were analyzed for Oil and Grease, Total Lead, and Total Metals. The data obtained from the investigation and the results of a prior sampling event were evaluated to determine the approximate vertical and lateral extent of petroleum product migration, the potential environmental effects of the petroleum product migration, and the need for additional studies or remedial .actions. This report was prepared to present our investigative procedures, findings and related conclusions and recommendations. 4.0 INVESTIGATIVE PROCEDURES The investigation consisted of subsurface exploration, and a laboratory testing program. The details of each of these phases are summarized in the following subsections. 4.1 Soil Borinq and Samplinq Locations: Four exploratory borings were drilled approximate to the former tank location to obtain Soil samples for laboratory analysis. The locations of the Soil borings are shown on Drawing No. 3. Soil boring B-I' was slant drilled at a 30 degree angle approximately 6 feet southwest from the center of the former tank Fresno Modesto Visalia Bakersfield NORTH PROJECT No. TL 988-099-02 'LEGEND F SOIL BORING LOCATION ENCE ------I FORMER TANK LOCATION FORMER PIPING LOCATION CAR LOT ASPHALTIC CONCRETE PAVEMENT x SOIL ~ORING LOCATIONS VALLEY OLDSMOBILE FACILITY 2600 "H" STREET BAKERSFIELD, CALIFORNIA X X ?. .'< -->~ X B-4 FORMER UNDERGROUND TAN~K LOCATIO[ BUILDING SCALE 1"=10' OR/),w N 8Y BMB 2-23-90 The Twining APPROVED BY HDM Loborolories, Inc.

The soil samples were analyzed in our laboratory for oil and grease. Soil boring B-2 was drilled approximately 8 feet northwest from t~e center of the former tank location to a depth of 26.5 feet BSG. The soil samples were analyzed for oil and grease and total lead. The soil sample obtained at 11.5 feet BSG was analyzed for total metals and total lead. Soil boring B-3 was drilled approximately in the center of the former tank location to a depth of 26.5 feet BSG. The soil samples were analyzed for oil and grease. Soil boring B-4 was drilled approximately 10 feet' northeast from the center of the former tank location to a depth of 26.5 feet BSG. The soil samples were analyzed for oil and grease. During the field investigation, it was not possible to drill any exploratory borings in the vicinity of the former waste oil pipeline, located west of the former tank location, because of limited drill rig access caused by a fence located 8 feet north of the building. ~4.1.1. Soil 'Sampling Procedures: The exploratory soil borings were drilled under the direction of a staff engineer from our firm, on October 28, 1988, using a Mobile B-40 truck-mounted drill rig equipped with 6-5/8 inch diamete~ hollow stem augers. Fresno Modesto Visalia Bakersfield TL 988-099-02 Page 10 The samples were obtained by driving a thin-walled steel sampler, equipped With three 2-1/2 inch diameter, 6-inch long brass sleeves, 18 inches into the soil. The ends of the sleeves were covered with teflon tape, capped with plastic fittings, and secured with synthetic tape, The bottom sleeve was retained for laboratory analysis. The soil contained in the upper 12 inches was retained on-Site with the drill cuttings. ~ Continuous logs of the soils encountered in the soil borings were recorded. The field soil classification was in accordance with · the Unified Soil Classification System and consisted of particle size, color, and other distinguishing features of the soil. Upon completion of .the drilling and sampling, the borings were backfilled with a sand-cement slurry. ~All drill cuttings generated from the borings were cOvered with visqueen and are presently stored on the site. Isaacs and BaJiley will be responsible for properly disposing of this material. The soil boring locations were determined by using a measuring tape with reference to the building located to the south of the former tank location as shown on the site plan, and should be considered accurate to within 1 foot. The elevations of the test borings were not determined as part of this investigation. The location of the test borings, are described on the soil boring logs in Appendix A. Fresno Modesto '/~salia Bakersfield TL 988-099-02 Page 11 4.1.2 Decontamination Procedures: Prior to drilling operations, the auger and a~ssociated drilling equipment were thoroughly cleaned using a high presSure hot water steam washer. The hot water washer had a pressure of 1,000 psi and water temperature of 200°F. In addition, the soil samplers were washed in a Trisodium Phosphate (TSP) solution, rinsed in water, and air dried prior to initial use and between each sampling event to preclude the possibility of cross-contamination between samples. 4.1.3 Sample Handlinq and Chain,of-Custody Procedures: Records were developed for all soil samples including: sampling date, sample type, location, and method of preservation. The sample containers were banded and Sealed with shipping seals, All samples were immediately placed on ice for shipment to our Fresno laboratory for analysis. Chain-of-custody procedures, described in "Test Methods for Evaluating Solid Waste", SW-846. U.S. EPA, May of 1988, Third Edition, were followed. A copy of the chain-of custody documentatiOn associated with the sampling, transport, and analysis of soil samples obtained during the investigation is presented in Appendix B. All' soil samples retrieved in the field were brought to our laboratory in Fresno, California. The driller in charge of the . field investigation carried both the samples and chain-of-custody form to the laboratory where he presented them to the' laboratory Fresno: Modesto Visalia Bakersfield TL 988-099-02 Page 12 director. The. director or an authorized analyst signed the chain- of-custody form, presented a duplicate copy to the driller, and processed the samples. The director's responsibilities included monitoring the progress of the samples and insuring the sample's integrity within'the laboratory. This involved assigning each sample a laboratory number and maintaining a cross-reference between the sample's field identification information and its laboratory identification. ~ The analyst's responsibilities included maintaining accurate records of the sample analyzed, along with the analytical data produced. This involved labeling chromatograms and maintaining the laboratory numbers on all subsamples taken from the samples submitted, labeling all glassware used in the analyses, and properly labeling sample extract containers with the sample's laboratory number. After the analyses were completed, the samples were transferred to a limited access, storage room. In addition, the chain-of-custody form, chrom'atograms, and other pertinent information are maintained for future reference. 4.1.4 Safety Work Plan: Due to the possibility of health hazards associated with exposure to various chemicals, field and laboratory personnel who could possibly come in contact with the samples obtained from the site were issued safety gear. This included disposable coveralls, rubber gloves, organic vapor 'masks, Fresno Modesto Visalia Bakersfield TL '988-099-02 Page 13 ~ubber boots, safety glasses, and hard hats. The field engineer and laboratory director were resporisible for the implementation of the safety work plan. 4.2 Laboratory Investiqation: Chemical tests were conducted o~ soil samples retrieved in the field. A description of the tests performed during this phase of the investigation is provided in the following subsections. 4.2.1 Chemicai Analysis: Analytical tests were performed to determine the presence and concentration of key petroleum constituents associated with the product stored in the tank. Based on the suspected petroleum prodluct discharge (waste oil), each soil sample was analyzed for the constituents of oil and grease as outlined in Table No. 2, using the listed methods. In addition, a Soil sample was analyzed for total metals and for total lead. The analytical methods used fOr the analysis of the samples were those approved by the EPA.

For this project, the laboratory director was in charge of creating and maintaining the program. Specific QA/QC procedures developed for this investigation are summarized as follows: Fresno Modesto Visalia Bakersfield TL 988-099-02 Page 15 Orqanic Analysis 1) Method blanks were run to insure that the glassware and reagents were free of interference from chemicals that could invalidate analyses; 2) Standards were prepared using the highest purity reference material available; 3)' Duplicates of the soil samples were' analyzed to monitor precision of the method; and 4) Duplicates of the soil samples were fortified to validate the accuracy of the method. Inorqanic Analysis 1) All glassware was acid rinsed to remove any metal contaminants; 2) Deionized water was monitored daily for quality; 3) Duplicates of the soil samples were analyzed to monitor precision of the method; and 4) Duplicates of the soil samples were fortified to validate the accuracy of the method. Twining maintains a service contract on all major instrumentation; gas ch.romatograph, atomic absorption, chromatograph and total organic carbon analyzers. All instruments are serviced on a regular basis to ensure their accurate calibration.. Fresno Modesto Visalia Bakersfield ~TL 988-099-02 Page 16 5.0 RESULTS AND FINDINGS The results of the field and laboratory investigations are summarized in the following subsections. 5.1 Soil Profile: The soil profil°e at the site consisted of pobrly graded silty sands undelrlain by interbedded sa.ndy silts and gravelly, sands to a depth of 26.5 feet BSG, the maximum depth explored. The foregoing is a general summary of the subsurface conditions encountered in the soil borings drilled for this study. Detailed descriptions of the con~ditions encountered in the borings drilled are presented on the boring logs in Appendix A. The stratification lines on the log represent the approximate boundary between soil types; the actual in-situ transition may be gradual. 5.2 Analytical Results of Soil Sample.

In addition, the data obtained were evaluated to assess the potential environmental effects of the migration. Finally, the .need for additional studies and remedial actions are discussed. The details of our evaluation are presented in the folloWing subsections. 6.1 Extent of Petroleum Product Miqrat.ion: An elevated concentration of oil and grease, 74,000 mg/kg at a depth of 6.5 feet BSG, was encountered in soil boring B-1 which was slant drilled beneath the building. The concentration of oil and grease attenuated to '15 mg/kg at a depth of 11.5. feet BSG, and to 10 mg/kg at a depth of 21' 5 feet BSG,. the maximum depth explored in soil boring B-1. Elevated concentrations of oil and grease, 13,000 mg/kg at. 6.5 feet BSG and 33,000 mg/kg at 11.5 feet BSG, were encountered in soil boring B-3 located at the center of the former tank location. The concentration of oil and grease attenuated to 30 mg/kg at a depth of 16.5 feet BSG. The analytical results of the soil samples retrieved from soil borings B-2 and B-4 revealed concentrations of Fresno Modesto Visalia Bakersfield TL 988-099-02 Page 20 oil and grease less than 50 mg/kg. The analytical results of the soil sample analyses from a previous sampling event (during the tank removal operation) revealed elevated concentrations of oil and grease, 67,823 mg/kg at a depth of 2 feet below the piping (app]roximately 7 feet BSG). The oil and ~rease concentration attenuated to 1,428 mg/kg at a 'depth of 6 feet below the .piping (approximately 11 feet BSG). No soil samples were taken below a depth of 11 feet BSG. Based on information proVided by Mr. Joe Canas of the KCEHD and on our past experience with oil and grease constituents, naturally occurring concentrations of oil and grease in soils range from 10 mg/kg to 50 mg/kg.' Thus, it would appear that the background levels of oil and grease occurring in the on-site soils are within naturally occurring ranges and that oil and grease concentrations detected in excess of 50 mg/kg are the result of petroleum product (waste oil) migration from the former underground tank. Based on the analytical results of the soil samples retrieved from the soil borings and from the previous sampling event, the known horizontal extent of soils containing elevated concentrations of oil and grease appears to be in a' circular area with a radius of about 6 feet centere~ on the former tank location. Given the granular nature of the on-site soils, it would be reasonable to assume that oil and grease migration has occurred in a vertical Fresno Modesto Visa[~a Bakersfield ~ TL 988-099-02 Page 21 direction asymmetrical around the vertical axis of the former tank location. The above data suggests that oil and grease may have migrated horizontally beneath the building located to the south of the former tank. The estimated horizontal extent of the oil and' grease migration is illustrated on Drawing No. 4. The vertical depth of soils containing elevated concentrations of oil and grease appears to be extending to a doepth between 11.5 feet and 16.5 feet BSG, in the vicinity of the former tank location. In addition, the analytical results of the soil sample analyses from the previous sampling event indicate that the soils containing elevated concentrations of oil and grease exist to a depth of at least 11 feet BSG beneath the location of ~he former piping. The known vertical extent of oil and grease migration beneath the former tank is illustrated on Drawing No. 5. It is estimated that approximately 70 cubic yards of soil at the former tank location is affected. The volume of affected soil b~eneath the former piping has not been determined. 6.2 Potential Environmental Effects: The analytical results of the soil sample analyses from this investigation indicate that elevated concentrations of key petroleum constituents exist on-site beneath the former waste oil tank and piping to a depth of at least 11.5 feet BSG. Depth to groundwater is approximately 165 feet BSG.

TL 988-099-02 Page 22 The average annual rainfall in the region is approximately 6 inches. Because the site is located on an alluvial plain, no known subsurface fracture exist. In addition, no man-made conduits wh'ich would increase the potential for migration of petroleUm products were identified during the investigation. The petroleum product in the on-site soils appears to be comprised of 'oil and grease as demonstrated by the analytical results of the soil sample analyses and the product history of the tank. Currently, no regulatory guidelines have been established for acceptable levels of oil and grease in soils. In light of the fact that the soils containing elevated concentrations of oil and grease at this site are separated from groundwater by a distance of approximately 150 feet, and the fact that oil and grease does not readily migrate in soils, there does not appear to be an immediate threa~ to groundwater due to the oil and grease contamination at this site, The analytical results of the soil samples from this investigation and from the previous sampling event revealed detectable concentrations of total lead. Based on the evaluation of the results of these findings it becomes apparent that as the concentration of oil and grease increases the concentrations of detectable total lead increases proportionately. Thus, it may be Fresno Modesto Visalia Bakersfield TL 988-099-02 Page 23 assumed that the soils which contain elevated oil and grease concentrations also .contain elevated lead concentrations. The analytical results of the soil sample analyses from the previous sampling event revealed an oil and grease concentration of 67,823 mg'/kg and a lead concentration of 59.0 mg/kg in soil sample ~No. 1, which was retrieved at a depth of 2 feet below the piping (7 feet BSG). The results of the analyses of sOil sample No. 1 for total lead, were compared to the Total Threshold Limit Concentration (TTLC) of. 1,000 mg/kg and the theoretical Soluble Threshold Limit Concentration (STLC) of 5 mg/1 (the theoretical STLC in mg/kg is 10 times greater than the STLC in mg/1), as outlined in the CalifOrnia Code' of Reg61ations (CCR), Title 22, Chapter 30, Article 11, Section 66700. Given the concentrations of lead detected, the potential exists for the soluble concentrations of lead to exceed the STLC for this site, which would classify all or part of the affected on-site soils as hazardous waste in accordance with the CCR criteria for hazardous wastes. The analytical results of the soil sample retrieved from soil boring B-2 at a depth of 11.5 feet BSG revealed detectable amounts of arsenic, barium, beryllium, chromium, copper, lead, mercury, thallium, vanadium, and zinc. All of these metals were detected in concentrations below their applicabl.e TTLC and STLC values designated by the California Code of Regulations, for hazardous Fresno MoOesto Visalia Bakersfield 988-099-02 Page 24 wastes. 6.3 Additional Studies and Remedial Action: Three remedial action alternatives for the area beneath the former underground waste oil tank were evaluated on a preliminary basis: 1) no action, 2)' soil removal and disposal at a State certified landfill, and 3) in-situ remediation by biological methods. The no action remedial action alternative would involve leaving in-place soils containing elevated concentrations of petroleum product' constituents and possibly hazardous levels of lead at the site. Regulatory agency approval would be required for this alternative. However, it is unlikely that. this approval would be granted until a Waste Extraction Test (WET) is performed on the soils to determine if they contain hazardous levels of lead. It should also be noted that leaving the soils containing elevated concentrations of oil and grease in-place would not achieve a clean closure and thus may effect future marketability and use of the property. In light of these'potential conditions, this alternative may not be feasible. The excavation and disposal at a State certified landfill remedial action alternative would involve physically removing the soils containing' elevated concentrations of oil and grease and disposing of the contaminated soil at a State'certified landfill. B~cause oil and grease contamination probably exists beneath the Fresno Modesto Visalia Bakersfield ~TL 988-099-02 Page 25 building located to the south of the former tank location it may not be possible to remove all of the contaminated soils without threat to the structural integrity of the building. However, it may be' feasible' to leave in-place a portion of the contaminated soils below the structure and still satisfactorily remediate this site. Considering the distance to groundwater below the effected .area, the migration characteristics of oil and grease in soils, and the fact that this area will be protected by the structure from moisture intrusion, this alternative may be feasible. It is recommended, however, that in the event that the existing stru~cture is removed that an additional Study be conducted to determine the extent of any remaining oil and grease contamination. If this remedial action alternative is considered, it is recommended that a structural engineer be consulted to evaluate the risk to the structure that may exist as a result of the excavation required. Soils should be removed from the area indicated in Drawings Nos. 3 and 4 to an estimated depth of 12 to 15 feet BSG, Or until all contaminated soil has been removed. The excavation could be achieved with a backhoe or sit, ilar equipment. Soil samples should be retrieved'from the excavated area and analyzed to determine the soluble oil and grease and total lead. The in-situ remedial action alternative would involve leaving the in-place soils containing elevated concentrations of oil and Fresno Modesto Visalia Bakersfield ~TL 988-099-02 Page 26 grease and remediating the affected area by introducing biological nutrients or cultures into the soils. This alternative would probably not be feasible for this site due to the small volume of soils involved 'and because the costs involved would probably outweigh those of the other alternatives proposed. In addition, this alternative is not feasible if it is deemed necessary for the soils to be remediated for hazardous levels of lead. The remedial action alternative should be selected after KCEHD has reviewed this report andl provided comments on the report findings and the alternative remedial actions. A remedial action plan (RAP) should be prepared after a remedial action alternative is chosen. 7.0 CONCLUSIONS On the basis of the findings of this investigation, we present the following conclusions: 7.1 The soil profile at the site generally consists of silty sands and poorly graded sands to a depth of 26.5 feet BSG, the maximum depth explored. 7.2 7.3 The horizontal extent of petroleum product migration is estimated to be located in a circular area centered on the former underground waste oil tank location with a radius of approximately 6 feet. The vertical extent of petroleum product migration is estimated to extend to a depth of between 11.5 feet and 16.5 feet BSG, beneath the former underground waste oil tank. Fresno Modesto Visalia Bakersfield TL 988-099-02 Page 27 7.4 7o5· 7.6 7.7 7.8 7.9 Petroleum product may have migrated horizontally beneath, the building located to the south of the former underground waste oil tank. The vertical extent of petroleum product migration beneath the location of the former piping located to the west of tlhe former waste oil tank is estimated to extend to a depth of at least 11 feet BSG. The affected soils may contain hazardous levels of lead which cou]ld restrict the method of remediation. The soils containing elevated levels of oil and grease and lead are separated from groundwater by approximately 150 feet BSG. It is unlikely that groundwater has been impacted by the petroleum product migration from the former waste oil tank. T~he excavation and disposal remedial action alternative would appear to be the most feasible. 8.0 RECOMMENDATIONS: On the basis of our evaluation of the field and laboratory data, we present the following recommendations. 8.1 A copy of this report should be submitted to the KCEHD for their review. 8.2 After review of this report by the KCEHD, a remediation option should be selected and a remedial action plan (RAP) should be developed to address' procedures and requirements for the remedial action. Fresno Modes~:o Visa~ia Bakersfield TL'988-099-02 Page 28 8.3 An additional'investigation should be conducted to determine the solubl~e concentrations of lead in the affected soils by 'the waste extraction method as outlined in the California Code of Regulations, Title 22. 9~0 LIMITATIONS The conclusions and recommendations presented in this report are based on the assumption that the soil and groundwater conditions and the chemical concentrations do not deviate from those disclosed in our published literature study, subsurface exploration and laboratory testing. If variations from our findings or undesirable conditions are found, The Twining Laboratories, Inc. should be notified so that supplemental conclusions and recommendations could be given. This report is provided with the understanding that it is the responsibility of the owner to transmit the information and recommendations of this report to the appropriate regulatory agencies. The conclusions and recommendations contained in this report are solely professional opinions derived in accordance with current standards of professional practice. The professional staff of The ,Twining Laboratories,~ Inc. strive to perform their services in a properly and professional manner with reasonable care and competence but are not infallible. We understand that there are risks of earth movement and property Fresno Modesto Visalia 8akerstield TL 988-099-02 Page 29 damage inherent in remedial actions of soil and groundwater contamination. We are unable to eliminate all risks; therefore, we· are unable to guarantee or warrant the results of our work. 10.0 CLOSING We appreciate the opportunity to be of service to you on this project.

Isaacs and Bailey September 1, 1988 Page 4 of Valley Olds West. 2.2 Previous Investigation. s: Previously, two soil samples were obtained by a tank removal contractor at depths of 2 feet and 6 feet beneath the invert of the abandoned underground storage tank~ These samples were analyzed for the presence and concentration of selected constituents. In general, the analytical results revealed varying concentrations of oil and grease at 2 feet and 6 feet beneath the tank. 2.3 Problem Statement: The area of concern regarding the project site is the extent of contaminated soil in the area of the underground storage tank. In a letter from Mr. Bill Scheide of the Kern County Health Department, Environmental }{ealth Division, Mr. Scheide indicates that his department requests a site characterization study to determine the extent of this contamination. Fresno Modesto Visalia Bakersfield I~aacs and Bailey September 1, 1988 Page 5 3.0 PURPOSE AND sCOPE OF INVESTIGATION The objectives of the proposed engineering investigation are presented as follows: Determine the existence and concentration of selected~ constituents in the soils in the area of the under- ground storage tank. Evaluate the findings ILo determine if adequate infor- mation has been developed by this investigation to define the general vertical and horizontal extent of contaminate migration lin the area of the underground storage tank.-This is a preliminary investigation. After the findings of this investigation have been reviewed, further investigation may be necessary to develope additional information regarding the extent of contaminate migration and concentrations in the soil. If adequate information has been developed by this investigation, address clean-up alternatives and dis- cuss possible mitigation measures which could be undertaken. The general scope of this investigation, which is deemed necessary to achieve the above referenced objectives is as follows: · Using a d'rilling rig, drill down to an'anticipated maximum depth of 25 feet below the surface· Obtain undisturbed soil samples at intervals of 5 feet starting at a depth of 5 or 10 feet and continuing to an anticipated maximum depth of 25 feet. Analyze selected Soil samples in the laboratory for the presence and concentration of seleCted constituents. Evaluate the data produced during the investigation to determine, if possible, the general extent of the constituent migration in the soil. Fresno Modesto Visalia 8akersheid Isaacs and Bailey September 1, 1988 Page 6 4.0 TECHNICAL APPROACH This section presents the details of our proposed field investigation and laboratory testing program. 4.1 Sampling Plan: In order to develope information to aid in determining the general vertical and horizontal extent of contaminant migration in the soils near' the underground storage tank, ~ locations shown on Drawing No. 2. Eowever, should discoloration or petroleum odOr be present in the samples-at a depth of 25 feet then and locations of' the borings were selected based on the information obtained from Mr. Cecil Bailey and Mr. Chuck Oliver regarding the previoUs investigations performed and the location of the underground tank. All field work associated with the collection of soil samples from the project site Would be supervised by an engineer from our firm. The borings would be term:[nated at an anticipated maximum depth of 25 feet.or when groundwater is reached. In addition, the borings would be terminated if auger refusal is encountered. The exploratory soil boreholes will be drilled at the proposed locations using a truck mounted drilling rig equipped with hollow stem continuous flight augers. The hollow stem augers will be used to ensure sample integrity by preventing soils from caving to the bottom of the borehole during drilling. Prior to drilling each borehole, the Fresno MoOesto Visaiia Bakersfield Isaacs and Bailey. September 1, 1988 Page 7 hollow stem augers will be steam cleaned to prevent cross-contamination between boreholes. ~]~until completion of the site characterization. 4.2 Soil Samplinu: Soil samples will be obtained from each boring at intervals of 5 feet starting at a depth of 5 or 10 feet below existing site grade. Once the required sampling depth has been reached, a representative soil sample will be obtained using a California Modified Sampler equipped with pre-cleaned brass tube liners and sample retainers. The sampler will be driven or pushed approximately 18 inches into the undisturbed soil ahead of the auger. Selected samples will be collected and submitted to the laboratory for analysis of appropriate constituents. Prior to being used for sampling, the brass tubes and samplers will be cleaned with a steam cleaner or a TSP solution to prevent introduction of any contaminants into the soil samples and to prevent cross-contamination between samples. The sample containers to be used consist of one and one-half inch by four' inch brass tubes. The brass tubes, pre-cleaned at the laboratory prior to use, are placed in the sampler and pushed or driven as described above to collect the soil samples. Upon removal from the borehole, the ends of each tube containing the ~~~b~ '~~!~ to identify the lithology penetrated described on discoloration or ordor from the sample would be noted. The ends of Fresno MoOesto Visa*,a Bakersfield Isaacs and Bailey September 1, 1988 Page 8 the samples would then be covered with aluminum foil and p'lastic caps. The caps will be taped to the tube to provide an airtight seal. Each sample will be appropriately marked on site to show the date, job number, borehole number and sample depth. Following marking of the samples, they will be sealed in plastic bags (to further protect from melt water), placed on ice in an ice chest and then shipped as such to the laboratory. All samples received at the laboratory may not be analyzed in the laboratory. We have anticipated for our estimated budget the laboratory analysis of three samples from each boring. 4.3 Analytical Procedures: The analytical procedures for this investigation are designed to determine the presence or absence of contaminants in the soil in the vicinity of the project. The. details of our analytical procedures are presented in the following sections. 4.3.1 SQil Ahalysis: Each soil sample subjected to laboratorY' analysis will be analyzed for the presence and concentrations of the following constituents: Type of An~lyis .Metho~ ~ Oil and Grease EPA SW-846: ~~i~ , Total Halogenated Hydrocarbons bPA SW-846: ~ Total Lead EPA SW-846: ~~ SW-846: Test Metho_d. for Evaluation of Solid W~$te, U.S. EPA, Office of Solid Waste and Emergency Response, July, 1982, 2nd Edition. Fresno Modesto Visalia Bakersfield Isaacs and Bailey September 1, .1988 Page 9 These substances are those listed for the analysis of soil samples for the detection of waste oil constituents in the Kern County Health Department HandbOok #UT 31] "Requirements for Permanent Closure of Underground Hazardous Substanc. e Storage Tanks". 4.4 0uality Assurance Plan:'. This section describes the field and analytical procedures to be followed throughout the investigation. 4.4.1 General Sample Collection and }{andling Procedures: Proper collection and handling are essential to ensure the quality of a sample. Each sample will be collected in a suitable container, preserved correctly for the intended analyses and stored for analysis for no longer than the maximum allowable holding time. Details on the sample collection and handling procedures used on this project can be found in the sections for soil sampling. 4.4.2 Sampl~ Id~Dtification an~ Chain-of-Custody Procedures: Sample identification and chain-of-custody procedures ensure sample integrity and documented sample possession from the time of collection to its ultimate disposal. Each sample container submitted for analysis will have a label affixed to identify the job number, sampler, date and time of sample collection and sample number unique to the sample. This information, in addition to a description of'the sample, sampling methodology, names of on-site personnel and any other pertinent field observations will. be recorded. All sample analysis will be performed by our laboratory. A chain-of-custody form will be used to record possession of the sample from time of collection to its Isaacs and Bailey September 1, 1988 Page 10 arrival at the laboratory. When the samples are shipped, the person in custody of them relinquishes the samples by signing the chain-of-custodY form and noting the time. The sample control officer at the laboratory verifies sample.integrity and confirms that it was collected in the proper containers, preserved correctly and that there is an adequate volume for analysis. If these conditions are met, the sample will be assigned a unique log number for identification throughout analysis and reporting. The log number will ]De recorded on the chain-of-custody form and in the legally required log book maintained at the laboratory. The sample description, date received, client's name and any other relevant information will also be recorded. 4.4.3 Analytical Ouality Assurance: In Addition to routine calibration of the analytical instruments with standards and blanks, the analyst is required to run duplicates and spikes on ten percent of the analyses to ensure an added' measure of precision and accuracy. Accuracy is also verified through the following: U.S. Environmental Protection Agency (EPA) and state certification results. Participation in inter-laboratory, or "round-robin" program. "Blind" samples are submitted by the laboratory quality assurance officer on a weekly basis. These are prepared from th'e National Bureau of Standards EPA reference standards. Fresno Moclesto V~$aha Bakersfield Isaacs and Bailey September 1, 1988 Page 11 e Verification of results with an alternative method. For example, calcium may be determined by atomic absorption, ion chromatography or titrimetric methods. Volatile organics may be determined through either purge and trap or liquid-liquid extraction methods. 4.4.4 Miscellaneous Checks of Accuracy: Where trace analysis is involved, purity of the solvents, reagents and gases employed has been of great concern. Our laboratory maintains a service contract on all major instrumentation: gas chromatographs, atomic absorption, ion chromatography and total organic carbon analyzers are serviced and maintained regularly. The above outlined quality assurance program has been more than sufficient for most projects. Additional quality assurance, such as sp. ikes and duplicates on all anaylses, can be provided if requested. 4.5 Site Safety Plan: This plan addresses safe~ty provisions employed during the investigative fi'eld work in the vicinity of the site. The objective of the plan is to describe procedures and actions to protect the worker and uninvolved parties from direct skin contact, inhalation, or ingestion of potentially hazardous materials that may be encountered at the site. The plan describes: 1) the nature of potential materials, 2) personnel responsibilities, 3) respiratory protection, 4) clean-up/decontamination procedures, and 5) emergenCy procedures. 4.5.1 The Nature of the Potential Materials: The materials that may be encounter during drilling at the site include waste oil Fresno Mo~esto Visaiia Bakersfield Isaacs and Bailey September 1, 1988 Page 12 constituents in soils. The provisions of this safety plan are designed to protect workers from the above described constituents. 4.5.2 Personnel Responsibilities: Key personnel directly involved in the investigation will be responsibl~ for monitoring the execution of safe work practices. These personnel will be responsible for knowing the provisions of the plan, communicating plan requirements to workers 'under their supervision and to site visitors and for enforcing the plan. 4.5.3. Respiratory Pr_~: l~alf-face respirators eq. uipped with an organic vapor cartridge are issued to all field personnel for their use when necessary during field opertaions. The field engineer will be responsible for determining the use of these respirators. 4.5.4 Personnel Protection: The des~ignated personnel prot~ective equipment has been selected to prevent field personnel from exposure to diesel fuel products that may be present at the site. To prevent direct skin contact, the following protective clothing will be. worn as appropriate while working at the site. 1. Hard hat with optional face shield. 2. Tyvek coveralls. 3. Butyl rubber and disposable vinyl gloves. 4. Neoprene boots, steel toe. 5. Goggles or safety glasses (if optional face shield not used on the hard hat). Fresno Modesto Visalia Bakersfield Isaacs and Bailey September 1, 1988 Page 13 The type of gloves will be determined by .the type of work being performed. Drilling persc, nnel will wear butyl rubber gloves when necessary due to their long duration contact with the subsurface materials. ~ Twining sampling personnel will wear disposable vinyl gloves when handling any sample. When required, personnel'protective equipment shall be put on before entering the immediate work area. The sleeves of the coveralls will be outside of the cuffs of the gloves tO facilitate removal of clothing with the least potential contamination of personnel. If at any time protective clothing (coveralls, boots or' gloves) becomes torn, wet or excessively soiled, it will be replaced immediately. No eating, drinking, or smoking will be allowed in the vicinity of the drilling operations. Twining Laboratories will designate a separate area on-site for eating and drinking. Smoking will not be allowed in the vicinity of the site, except in designated areas. No contact lenses will be worn by field personnel. 4.5.5 Clean-Up/Decontamination Procedures: Property clean-up/decontamination procedures are essential to prevent transporting potentially contaminated material from the site and to protect the health of field personnel. At the end of the workday, the following procedures will be used as appropriate to allow for the safe removal and decontamination of protective equipment. Fresno Modesto Visalia Bakersfield Isaacs and Bailey September. 1, 1988 page 14 1. Boots and gloves will be washed with soap and tap water, then rinsed before removal. 2. Boots and coveralls will be removed and may be placed in a designated drum for proper disposal. 3. Gloves will then be removed and may also be placed in the designated drum; hands will be washed with soap and water. 4.5.6 Emergency Procedures: Symptoms of direct exposure to significant concentrations of gasoline and/or diesel fuel products include: irritation of the eyes, nose and skin; vomiting; headache, dizziness, light-headedness; lack of coordination; nausea and~ unconsciousness. If any of these Symptoms develop, operations will be stopped and medical attention obtained as necessary. If any of these symptoms occur, first aid procedures for direct exposure to the on-site materials are: 1. Skin: Remove contaminated clothing immediately. Flush affected area immediately with water, then .wash with soap and water. Eyes: Hold the eyelid open and flush with water. LUngs: Move to freah air immediately; give arti- ficial respiration as necessary.
