(Delta), at the former bulk petroleum storage and dispensing -facility owned by Pence Petroleum Company. The location of the facility is 920 East TruxtunAvenue in Bakersfield, California (Site). ;1.1 Purnose of Assessment The site assessment was requested by the Kern County Health Department, Division of Environmental Health, to determine the extent of petroleum product contamination identified in soil samples collected after removal of underground storage tanks from the Site. The objectives of the assessment, as authori- :~ed by Pence Petroleum Company and its insurer, Federated Insurance Company, were the following: o Evaluate the Site's geologic characteristics. o Evaluate the horizontal and vertical extent of petroleum contamination in the soil. o Assess the overall impact of the contamination on the surrounding environment. o Evaluate remedial action alternatives. ;1.2 Scone of Work The scope of work included the following: o Performing a detailed Site reconnaissance, including a well search within a one-mile radius of the Site. o Drilling five standard penetration, holløw stem auger soil borings and collecting soil samples at two-and-one-half-foot and five-foot intervals in the boreholes for classification of soil type and organic contaminant screening. .., ...;..;.;.;:..:.,...... -Q 1'- r"~ r: I.

The street address is 920 East Truxtun Avenue in Bakersfield, California. The Site is bordered to the south by Truxtun A venue, to the east by Owens Street, to the north by 19th Street, and to the west by a vacant lot. The eastern two-thirds of the Site previously contained the underground storage tanks and is currently a vacant lot. The western one-third of the Site contains a warehouse building and a house. The bulk plant was in operation until August 1987. All fuel storage and dispensing facilities were removed at that time. Nine underground storage tanks previously existed at the Site. The approximate location and size of each tank, the bulk loading rack, and the dispensing station are presented on Figure 2. The approximate volumes and former contents of each tank are also shown on Figure 2. 2.2 Site Historv The following Site history was developed from conversations between Mr. Charles Pence of Pence Petroleum Company and Delta staff members. A bulk petroleum storage and dispensing plant was first built on the central portion of the Site in the late 1930's and consisted of eight underground storage tanks and a dispensing system. The Site was originally paved, and a gas station with a waste oil storage tank was built on the eastern portion of the Site. The gas station utilized three of the underground storage tanks from the bulk plant. The Site was operated by a Beacon Oil jobber prior to 1951. From 1951 to 1973, the bulk petroleum facility was operated by Douglas Oil Company, and Mr. Pence sold bulk fuels on consignment. The retail gasoline station was closed and demolished in 1965. No tanks were excavated at that time. Pence Petroleum 'Company leased the Site froin DöUglas Oil Company from1973 1intilI978, when Pence Petroleum .---,"-.-~.._._-------"..""""--,_,,,~,,--. ~ _¿.---'-_--..t-~._':I.~-~___._-_;.::~_:.:._~:.:J,::..:.~,,:.':,.....~"t1:":;:;'.'_:. . ···:·'::»:>';':';';';L~-';;:';·':':'~~~1rr."'t·.:;:.:~~...:.^,'~-.~:,.~:·.:' :.......:....:;L.¡,;:..-.;.:r~;.~..~. ,[ I I I Results of Phase I Site Assessment Pen,:e Petroleum Company Delta Project #40-87:-295 Pag.a 7 FIGURE '1 SITE LOCATION PENCE PETROLEUM " 8.AJ<ERSFIELD, CALIFORNIA DELTA NO. 40-87~295 "" . -, .. -.-.. -" ---- ----~------ ....- r- r' '~rÞl:u';~ .,::: ~ -,;~,;;:= ----.- - "\~\\Y'''~~Ì'i1I'ì :('.' .:;:S' .; '" :.J'j!'!' . - ::.- --- , . ~ J ..

Inventory records for the facility operations prior to 1973 are not available. - .- -_._.-.._--~, -- -. ~._"-_._-- 2.2.2 Tank Testing Data Pence Petroleum reports that Tank No.2 was the only tank op~rated during 1987. Tank No.2, the connecting product lines, vent lines and pumps were tested using county-approved methods and reported "tight" in February 1987. The remaining tanks at the Site were not used after July 1986 and were not tested. Prior to July 1986 the tanks were periodically gauged by measuring the product level in the tanks. 2.2.3 Investigation for Contamination After Tank Excavation Following removal of the underground storage tanks, 42 soil samples were collected for petroleum hydrocarbon analysis. The samples were collected at depths of approximately 14 and 18 feet below grade (two and six feet below the bottoms of the tanks) at each tank location and the bulk loading rack and the dispensing station. The samples were collected by Dwight Environmental and analyzed by SMc; Laboratory for Total Petroleum Hydrocarbons (TPH) by EPA Method 9071 and for Total Volatile Hydrocarbons (TVH) by EPA Method 5020/8020. Each test method and the significance of the results obtained are discussed in Appendix A, Section 2.0. The analytical results are provided in Appendix B.

A second zone of oil and grease contamination is centered at the north end of Tank 8, extending to the north ends of Tanks 7 and 9. The level of contamination in this zone is only slightly greater than 100 ppm, with the highest analytical result at 155 ppm. The volatile hydrocarbon contamination (TVH) was also found to be present in two zones. The first is c~~ntered at the north end of Tank 5 and extends to the south end of Tank 5 and the north end of Tank 6.

The Central Valley is an elongated valley approximate- ly 450 miles in length and 50 miles in width. The valley is bordered by the Sierra Neyada Mountains «I - Results of Phase I Site Assessment Pence Petroleum Company Delta Project #40-87-295 Page 13 \ ' on the east, the Transverse Ranges on the south, the Coast Ranges to the west and the Klamath Mountains on the north. The Geologic Map of California (1977) indicates that the Site is underlain by undifferentiated Quaternary unconsolidated to semi-consolidated non-marine alluvium lake, playa ¡ and terrace deposits. \ ___H~h. _ I'" 2.4 Re!!ional Hvdrolo!!v 1 : ' The Site is located in the northern portion of the Kern County Improvement District No.4, as defined by the Kern County Water Agency's 1986 Water Supply Report (May 1987). This report also indicates that the depth to ground water' in the area of the Site is between 200 and 250 feet below the ground surface. Plate 4, Depth to Ground Water, indicates a depth of approximately 200 feet for ground water in Section 29. A well search conducted through the Kern County Water Agency identified three municipal, wells within a one-mile radius of the Site. Table 2 is a review of the depth to static- water level and well locations. The data indicates that the average static-water level in the area of the Site is approximately 200 feet below the ground surface. This information is confirmed by the Water Supply Report. Long term average precipitation for Bakersfield as reported in the Kern County Water Agency's Water Supply Report is approximately 5.5 inches per year. Normal evaporation is approximately 64 inches per year. i' I I , i I,' ,.-.. ~--_.,-.__.,_.. e e Results of Phase I.site Assessment :Pence Petroleum Company :Delta Project #40-87-295 :Page 14 TABLE 2 Static Water Levels of Three Municipal Wells WitQin One- Mile Radius of Pence Petroleum Site '-- ~-- ,-~--~-~.. -~ "'" ,~_._- '~'-' ~,-- .

The top soil is underlain by coarse alluvium, consisting of interbedded sand and silty sands with lenses of silt throughout. The coarse alluvium is consistent to depths of between 50 to 60 feet below the ground surface. Underlying the coarse alluvium is fine alluvium, I consisting of silts and sandy silts, with lenses of silty sand. Penetration tests completed during soil sampling indicate the granular soils range in relative density from firm to very dense, and the cohesive soils range in consistency from very stiff to hard. All soil borings were terminated within the fine alluvial silts. Borings were sealed with a cement-sand-bentonite grout. 3.2 Ground Water No ground water was encountered in any of the test borings.

The soil samples were screened for the presence of volatile hydrocarbons using an hNu portable photoionization detector. The results of the hNu screening are presented on the soil profiles, Figures 4 and 5. Selected samples were submitted for laboratory analysis on-the-basisòf hNu indications. These samples were analyzed for benzene, toluene, xylene (BTX); ethylbenzene (E); , 1,2-dichloroethane (EDC); ethylene dibromide (ED B); and total purgeable petroleum hydrocarbons (TPPH). The results of these analyses are summarized in Table 3. Samples are referenced by boring number, sample number, and the depth below grade at which the sample was collected. Results are presented in parts per million (PPM). Laboratory analysis results are found in Appendix D. In general, petroleum hydrocarbons were found in all of the soil borings. The highest level of con- tamination (270 ppm TPPH) was found at 41.0 feet below the ground surface in Boring B-1, located near the ~_enteL()f the tan~._~~~~yªti9A.,are~. Hydrocarbon contamination was detected from 56 to 80 feet below the ground surface but at levels less than I ppm. Figures 6, 7 and 8 show the horizontal and vertical extent of soil contamination based on laboratory analysis. No levels of soil contamination greater than I ppm TPPH were found in borings B-3, B-4 and B-5. Sample B-2-9, taken at 51.5 feet !below the ground surface, was found to contain 1.3 ppm TPPH.

A review of background information referenced in Section 2.4 indicates the level of ground water at the Site is appr~~i~a.tely. ~O~oE~.e~_~~~~w.th~~.~~~~~d _s~rf"ace.

Fine-grained alluvium consisting primarily of silt was found from 55 feet to 81.5 feet. No borings were advanced more than 81.5 feet. The Kern County Water Agency Water Supply Report indicates that long term average annual rainfall for Bakersfield is about 5.5 inches, and the normal annual evaporation is about 64 inches. It is unlikely that precipitation will result in percolation to the water table. The site is located in an industrial area, and the percentage of runoff will be high. The fraction of precipitation that infiltrates is not likely to percolate more than a few inches into the surface soil. Use of the Water Balance Method developed by Thornwaite and Mather can be used to determine the potential percolation based on potential evapotranspiration, precipitation, surface runoff, infiltration, and soil moisture storage. However, for arid areas such as Bakersfield, analysis indicates that the soil moisture at the end of the wet season win be below field capacity. Field capacity is defined as the maximum moisture content which a soil can retain in a gravitational field without producing con- tinuous downward percolation.

Tank 9 was used for storage of waste oil from the servi~~ station, and soil samPles(~~alyzed for TPH (oil and grease). Tanks 5, 7 and 8 were used - . for storage of gasoline for the service station. Tank 6 was seldom used, as it could only be emptied , by pumping out of the-fill connection.

Soil samples collected from the e:xcavation of the bulk fuels loading rack and the dispensing station were analyzed for BTX and E, TVH, and TPH (oil and grease). The analyses performed were adequate for identification of the con- taminants most likely to be present in each area. The plotted analytical results indicate two areas of oil and grease contamination, one centered between Tanks 2 and 3 and one centered at the north ends of Tanks 7 and 8; and two areas of volatile hydrocarbon contamination, one centered at Tank 5 and one centered at the north ends of Tanks 7 and 8. Since the piping connections were located at the south ends of Tanks 7 and 8, and since it was not noted whether holes were found in the tanks during excavation, it is possible that the ~ample locations may have been reversed, either in the field or in the laboratory. If the analytical results from the north and south ends of Tanks 7 and 8 were ~e~~~~d'-"th~ed data would indi- c;ate only one area of contamination. ---- ----------' ~- \. ,,/ , .- ~:t.3 Soil Borine: Analvtical Results Physical observations (odor, appearance and portable photo ionization detector screening) were used in the field to screen recovered soil samples for volatile hydrocarbons. The results are presented in the boring logs in Appendix C and on the soil profiles provided on Figures 4 and 5. Verification or Quantification of the field observations was made by submitting 16 soil samples to the laboratory to determine con- centrations of representative petroleum compounds. A complete set of laboratory reports for samples collected by Delta for analysis is contained in Appendix D. A summary of the analytical results is presented in Table 3.

The vertical extent of contaminant migration appears to be inhibited at the interface between the coarse and fine alluvium.

Since samples were not analyzed at each 5-foot interval, the highest result of analysis either above or below any 5-foot interval was used at that interval.

The majority of contamination in the area where Tanks 1 through 4 and Tank 9 were located is in the form of low-volatility petroleum hydrocarbons, i.e., oil and grease. The majority of contamination in the area where Tanks 5 through 8 were located is in the form of volatile petroleum hydrocarbons. .~.i" o Levels of contamination of low-volatility hydrocarbons range from 7,940 ppm TPH two feet below the elevation at which tank bottoms were located to 1,365 ppm TPH four feet deeper. These levels decrease to less than 100 ppm TPHnear the perimeter of the excavated area. o Levels of contamination from vol~tile hydrocarbons range from 404 ppm TPPH near the elevation at which the tank bottoms were located to less than 1 ppm TPPH at a depth of 55 feet below the ground surface. o The amount of volatile petroleum hydrocarbons present is estimated to be about 50 gallons. .,' I 1- I 1 I [, " [ ~ - - - Results of Phase I Site Assessment Pence Petroleum Company Delta Project #=40-87-295 ¡Page 30 ~ ,"- ",¡vir: _/<:.- . , ,ý '. ...,\ \...-.. o \j--(jl The horizontal extent of contamination is defined by test borings B-2, B-3, B-4 and B-5. o The geologic setting includes dense, fine-grain. alluvium that inhibits downward migration of .-' contaminants. -. , /,p7:> o The hYdrOlO~ic settin~in~~des ~dePth ~o groun~ w~~e; of ~~p~o~¡~~~e¡~e9~ f::-~, :~~;a~~-- long term precipitation of about 5.5 inches per year, and normal evaporation of about 64 inches per year. - ------. -_.~.,- -"~--. -~-....- . ~- -----' o. -/Levels of soil contamination are well below the acceptable standards as set by LUFT / / guidelines.

Three alternatives of remediation are considered practical for the Site: .. -~ ~-~ "- o Partial Excavation. o In-Situ Remediation by Soil Venting. o No Action. The following criteria will be used in evaluating these alternatives: o The potential for further environmental impact o The mitigation of present impact to the environment o The potential environmental impact during remediation o Cost benefits o Performance schedule. :6.1 Partial Excavation The purpose of partial excavation is to remove the core of contamination. This process would involve I~xcavation and off-site disposal of soil contaminated to levels greater than 100 ppm TPPH. The depth of the excavation and the Site geology will necessitate an engineered and shored excavation. Excavated , .~ 'i (, ,(t.:~ '-, soils would be taken to a Class II disposal site.

The beneficial effect of partial, excavation as aremediation alternative is the reduction of contamination levels to. the point where natural biodegradation would occur in a shorter period of time than if none of the contaminated soil was removed. Table 6 presents a cost estimate for the partial excavation remediation alternative. Estimates are based on costs from representative Delta projects.

A typical soil venting system wouìd consist of multiple vacuum extraction wells and a carbon emission control system. Soil venting would reduce the level' of'---' . volatile hydrocarbon contamination and mitigate the potential for further environmental impact.' However, soil venting would not reduce the relatively large concentrations of non-volatile petroleum hydrocarbons. Because of the small volume of volatile contaminants, the depth at which contaminants are located below grade, and the depth to the water taþle, it is likely that there will be no further environmental impact. An adverse effect of soil venting is the limitation of land use placed on the owner during the remediation effort. The current property owner, Charles Pence, has expressed an interest in selling the Site and the relatively long period of time needed for soil venting may present a hardship to him. A beneficial effect of soil venting is the reduction of contamination levels to the point where natural biodegradation would occur in a shorter period of time. Table 8 presents a cost estimate for in-situ soil venting. Estimates are based on a three-well system. Additional costs for system maintenance, air monitoring and soil monitoring are included. The total cost for in-situ remediation by soil venting estimated to be $88,000.00. I- I fH I' .

'_.n_ ~";;..;_.::::;,,:._~..::::....-._"';'-':::"'=':::; -. . steam-cleaned between borings. To reduce cross-contamination between samples, the split-barrel sampler was washed in a soap solution and double rinsed between each sampling event. Soil sampling was done in accordance with ASTM 1586-854. Using this procedure, a 2-inch O.D. split- barrel sampler or 2-inch I.D. California type sampler was driven into the soil by a 140-pound weight falling 30 inches. After an initial set of 6 inches, the number of blows required to drive the sampler an additional 12 inches is known as the penetration resistance, or the "N" value. The N value is an index of the relative density of granular soils and the consistency of cohesive soils. Upon recovery, a portion of the soil sample was placed into a glass jar and sealed for later screen- ing with a portable photoionization detector. A second portion of the soil sample was used for classification. A third portion of the soil sample was collected in a brass tube and stored at approximately 40C for transport to the laboratory. A California State Certified Laboratory was used to perform the chemical analyses. 1.2 Soil Classification -' As the samples were obtained in the field, they were visually and manually classified by the Delta Geologist or EngÍneer in accordance with ASTM:D 2488-84. Representative portions of the samples may e e '" be returned to the laboratory for further examination and for verification of the field classifica- tion.

""--1---- .. - 1- , I ! , I - --- e e 2.0 ANAL YTICAL PROCEDURES The analytical procedures listed below and defined in "Test Methods for Evaluating Solid Waste" (EPA, - -- November 1986) were used for analysis of soil samples. ~u Total Petroleum Hydrocarbons by EPA Method 9071 ."-_.~" . ..::-~- --. --- As described in the Scope and Application, "Method 9071 is used when relatively polar, heavy petrol- ~mm fractions are present, or when the levels of nonvolatile greases challenge the solubility limit of the solvent." This method was used for analysis of soil samples collected after the excavation of all nine tanks, the bul~ fuel loading rack, and the dispensing station. The results of analysis indicate the presence of weathered, partially degraded diesel fuels, kerosenes, and gasolines. The' results of this analysis are reported as Total Petroleum Hydrocarbons (TPH) and are plotted on Figures 6, 7, and 8. ~~.2 Total Volatile Hvdrocarbons by EPA Method 3810/8020 As described in the Scope and Application, "Method 3810 (formerly Method 5~20) is a static headspace technique for extracting volatile organic compounds from samples." This method is recommended as a / screening procedure for more accurate determinative methods (such as Method 8020). From the Scope and Application, "Method 8020 is used to determine the concentration of various aromatic volatile organic compounds." The results of analyses are reported as Total Volatile Hydrocarbons (TVH) and are plotted on Figures 6, 7, and 8. ¡ e e ~~.3 Gas Chromatol!raDhv/Mass SDectrometrv for Volatile Orl!anics bv EPA Method 8240 __The_analyses on samples obtai!led from soil b()rings were peñormed using EPA Method 8240. This -..-. "-.--.- method utilizes gas chromatography/mass spectrometry to determine volatile organic compounds in a variety of solid waste matrices. It is applicable to nearly all types of samples, including soils ~lI1d sepiments, and is based on a purge and trap procedure. The method can be used to quantify most _ vc~la~ile organic compo~~~s that have boiling points below 200oC. Results are reported_ as !.ot~l _ .___ Purgeable Petroleum Hydrocarbons (TPPH). The results of analysis from Method 8240 are similar to I· , determining the extent of contamination by volatile petroleum compounds, the results may be those obtained from Method 8020, differing in limits of detection. However, for the purpose of c:onsidered comparable. e e 3.0 QUALITY ASSURANCE PLAN This section describes the quality assurance procedures that were followed throughout the investigation. '" ;3.1 General Samole Collection and Handline: Procedures I I L. Proper collection and handling were essential to ensure the quality of a sample. Each sample was ,:::ollected in a suitable container, preserved correctly for the intended analyses, and stored for :analysis for not longer than the maximum allowable holding time. Details on the sample collection :and handling procedures to be used on this project can be found in Section 1.0 of this appendix for soil samples. ,3.2 Sam Die Identification and Chain-or-Custody Procedures Sample identification and chain-of -custody procedures ensure sample integrity and document sample possession from the time of collection to its ultimate disposal. Each sample container submitted for analysis had a label affixed to identify the job number, sampler, date and time of sample collection, and a sample number unique to that sample. This information, in addition to a description of the sample, field measurements made, sampling methodology, names of on-site personnel, and any other pertinent field observations was recorded on the borehole log or in the field records. All samples collected by Delta personnel were analyzed by Central Coast Analytical Services in San Luis Obispo, California. A chain-of -custody form was used to record possession of the sample from time of collection to its e e arrival at the laboratory. When the samples were shipped, the person in custody of them relinquished the samples by signing the chain-of -custody form and noting the time. The sample control officer at the laboratory verified sample integrity and confirmed that it was collected in the proper container, ¡preserved correctly, and that there was an adequate volume for analysis. ,- These conditions met, the sample was assigned a unique log number for identification throughout I analysis and reporting. The log number was recorded on the chain-of-custody form and in the legally ! " \ required log book Central Coast Analytical Service maintains at the laboratory. The sample descrip- ". ..-".- -- -- tion, date received, client's name, and any other relevant information was also recorded. 3.3 Analvtical Qualitv Assurance In addition to routine calibration of the analytical instruments with standards and blanks, the analyst is required to run duplicates and spikes on 10 percent of the analyses to ensure an added measure of precision and accuracy. Accuracy was also verified through the fOllowing: o U.S. Environmental Protection Agency (EPA) and state certification results. o Participation in inter-laboratory or "round-robin" program. o 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. e e I, ~1.4 Miscellaneous Checks of Accuracv ¡ Where trace analysis is }nvolved, purity of the solvents, reagents, and gases employed is of great <:oncern. Central Coast Analytical Services maintains a service contract on all major'" instrumentation; gas chromatographs, atomic absorption, ion chromatography and total organic carbon I analy~ers were all serviced and maintained regularly. , The above program is more than sufficient for most needs. Additional quality assurance, such as spikes and duplicates on all analyses, were provided if requested. ~. ¡ ,.. i ì \ I ¡, e APPENDIX B e Laboratory Analysis Results from Tank Pull ., , \ ¡ r I r ¡ I , e e SMC LaboratoJ~y Analytical Chemistry 3155 Pegasus Drive P. 0 .

Boring logs taken during the general risk appraisal can b~ used to answer questions 5-8. In addition, analytical results of the soil samples taken during the general risk appraisal can be used to answer questions 3 and 4. The above checklist contains questions which are designed to identify sites with environmental conditions which could produce a greater risk to ground water than was modeled. The results of the general risk appraisal are most applicable if all of the questions on the checklist can be answered "no" with reasonable certainty. If any of the questions on the checklist cannot be answered "no", then the results of the general risk appraisal may be less valid. 2.

Soil boring logs completed at the time of drilling are contained in Appendix B. The locations of the soil borings are indicated in Figure 2. The locations of.soil cross-sections constructed through the borings are shown in figure 3. Soil cross-sections are presented in Figures 4 and 5. Soil borings B-6, B-7. and B-8 were advanced to 64.5, 66.5, and 71.5 feet below grade, respectively. A review of the boring logs indicates that the site is underlain by a layer of coarse alluvium and a deeper layer of fine alluvium. Both layers consist of unconsolidated silty sands, sands, sandy-silts, and silts. The area in and around the underground storage tank excavation has been completely disturbed and/or replaced by fill to a depth of about 16 feet. Generally, the fill consists of silty sands with occasional gravels. The natural topsoil encountered in soil boring B-5, which is locat~d outside the area of the tank excavations, is a silt. The topsoil is underlain by coarse alluvium consisting of interbedded sand and silty sands with lenses of silt throughout. The coarse alluvium is consistent to depths of between 50 to'60 feefbelòwthe ground surface. Underlying the coarse áihivium is fine aIluviüm c-ònsisting - '''''.',--. --. ,..

Penetration tests completed during soil sampling indicate the granular soils range in relative density from firm to very dense, and the cohesive soils range in consistency from very stiff to hard. Soil borings B-6, B- 7, and B-8 were terminated within the fine alluvial silts. , '.0 Soil borings- B-9 through B-14 were advanced to a total depth of 8' feet belowgrade;-o' These soil- _.-_.~_.~-'-.~,. borings were used to evaluate soil conditions immediately below the previously existing underground fuel storage tank locations. Soil boring B-15 was advanced to a total depth of 190 feet below grade. A review of the soil boring log for B-15 indicates that the fine alluvium is continuous to 110 feet below grade'. At approximately 110 feet below grade, a layer of silt with lenses of fine to coarse sand was encountered. The silt layer is continuous to approximately 178 feet below grade. At 178 feet below grade, a sandy gravel was encountered. The sandy gravel continued to 190 feet below grade. All soil borings were backfilled to the surface with a cement-bentonite mix. 3.2 Ground Water Ground water was encountered in soil boring B-15 in the sandy gravel at 187 feet below grade. No odors were apparent in soil boring B-15, and no soil samples were collected. 3.3 Petroleum Constituents in Soils Soil borings B-1 through B-5 were advanced during Delta's initial site investigation in October 1987. Soil samples collected from soil borings B-1 through B-5 indicated that low boiling range petroleum constituents (gasoline) were present with high boiling range petroleum constituents (diesel). TPH concentrations ranged from 270 ppm in B-1 at 41 feet below grade to below the 0.1 parts per million (ppm) detection limit in B-2 and B-3 at 81.5 feet below grade.

Petroleum hydrocarbons were found in all soil borings except B-15. The highest level of contamination (1,400 ppm TPH) was found at approximately 28.5 feet below grade in soil boring -----:Ï3-6,between the tanks numbered 2 and 3 in Figure 2. Petroleum hydrocarbons were detected in soil- borings B-6, B- 7, and B-8. At depths from 40 feet below grade to the bottom of each boring, the TPH concentrations were below the Practical Quantification Limit (PQL) of 0.5 ppm TPH. Be-nzene and TPH concentrations are noted on the soil cross-sections shown in Figures 4 and 5. I Soil borings B-9 through B-14 were advanced to a total depth of 8 feet below grade. Samples were -. - collëcted froin the silty sandS júst below the fiUto De- representative o(the soils below the former- - ----.-'- underground fuel storage tank locations. Petroleum hydrocarbon concentrations varied from 450 ppm TPH in soil boring B--l2 to below the PQL of 0.5 ppm TPH in soil boring B-ll. The benzene concentrations varied from 0.43 to below the PQL of 5 parts per billion (ppb), respectively. Soil samples collected from soil borings B-8, B-9, and B-IO were analyzed for total lead content by EPA Method 7240. These samples were selected based on their proximity to the locations of the underground tanks containing regular and premium leaded gasoline. The soil sample collected from B-8 at a depth of 10 feet below grade contained 4 milligrams/kilogram (mg/kg) (ppm) lead. The soil sample collected from B-9 at a depth of 6.5 feet below grade contained 4 ppm lead. The soil sample collected from B-1 0 at a depth of 6.5 feet below grade contained I ppm lead. The laboratory report for the lead analyses is contained in Appendix C. The analytical reports classified the petroleum constituents as gasoline or weathered gasoline in all of the samples submitted for analysis. 4.0 DISCUSSION OF RESULTS \, 4.1 Hvdroe:eoloe:ic Settine: Soil boring B-15 indicates that ground water is approximately 187 feet below the ground surface. Ground water contamination was not demonstrated at the site. Coarse alluvium consisting of sands and silty sands with lenses of silt is found in an interval from 10 to 55 feet below the ground surface. Fine-grained alluvium consisting primarily of silt was found from 55 to 110 feet. No borings were advanced more than 81.5 feet. Another fine-grained alluvium with fine to coarse sand lenses extends from 110 feet to the water bearing sandy gravel encountered at 178 feet below the surface. The Kern County Water Agency Water Supply Report indicates that long-term average annual rainfall for Bakersfield is about 5.5 :, -. . --'I·, ,- I \ e e ADDENDUM TO PHASE I SITE INVESTIGATION Pence Petroleum 920 East Truxtun Avenué, Bakersfield, CA Delta Project No; 40-87-296 Page 9 inches, and the normal annual evaporation is about 64 inches. It is unlikely that precipitation will re~.ul~ in percolati~.n tothe_~a!er_~ble. The site is l.?cated i~ an industrial area, and the percentage 'of runoff will be high. The fraction of precipitation that infiltrates is not likely to percolate more than a few inches into the suñace soil. Use of the Water Balance Method developed by Thornwaite and Mather can be used to determine the potential percolation based on potential evapotranspiration, precipitation, suñace runoff, infiltration, and soil moisture storage. However, for arid areas such as Bákersfield, analysis indicates that the soil moisture at the end of the wet season will be below f~~ld capacity. ~ield capacity is ~efine~.as ~~,maximum moisture content which a so~l canu_~etain in a gravitational field without producing continuous downward percolation. Evapotranspiration during the ensuing dry season would further reduce soil moisture. Natural field and climatologic conditions result in a low probability of percolation to the water table. , .- .__.~-~-- -. - 4.2 Soil Boring: Analvtical Results Physical observations (odor, appearance, and portable PID screening) were used in the field to screen recovered soil ,samples for volatile hydrocarbons. The results are presented in the boring logs in Appendix B and on the soil profiles provided in Figures 4 and S. Verification or Quantification of the field observations was made by submitting 46 soil samples to the laboratory to determine concentrations of representative petroleum compounds. A complete set of laboratory reports for samples collected by Delta for analysis is contained in Appendix C. A summary of the analytical results is presented in Table I-B. The locations of borings were selected to define the extent of petroleum constituents in soil. The analyses to be performed were selected based on the potential impact presented by petroleum constituents. Analyses of the soil samples collected from below the leaded fuel tank locations indicate that the total lead content in the soils is less than S ppm. Soil boring analytical results indicate that the horizontal extent of petroleum constituent distribution is confined to the area within the area within the site. The nine additional soil borings confirm that the petroleum constituents app.ear to be distributed through an interval of between about 10 to about SS feet below the ground s~rface, which is the approximate location of the bottom of the coarse alluvium. The vertical extent of petroleum constituents migration appears to be inhibited at the interface between the coarse and fine alluvium. The minimal seepage of petroleum constituents into the underlying fine alluvium is due to both an increase in soil densities and a decrease in grain size. .. ~---- ~... .- -- ---. - ~.. _ ", _"-'.C._ "_h _ ,,"_'--_. ~_- ! .~ " I ¡ \ ' ---I. ! e e ADDENDUM TO PHASE I SITE INVESTIGATION Pence Petroleum 920 East Truxtun Avenue, Bakersfield, CA Delta Project No. 40-87-'296 Page 10 4.3 Petroleum Constituent Mie:ration Upon release to the environment, petroleum distillates will initially migrate downward under the force of gravity. Individual components will evaporate in the soil pore spaces and diffuse according to the concentration gradient in all directions. Migration will be affected by several factors, including affinity to soil grains, density of the soil, and the organic content of the soil. The composition of the distillate mixture in the soil will also be affected by the varying soil affinities of individual components, varying diffusivities of individual components, the dynamic changes of the ~omposition of the mixture following adsorption to soil grains, and natural biological degradation ,_ jn the soils. A careful review of the analytical results obtained from soil samples taken from soil borings B-1 through B-3 indicates that as a general rule the percent of benzene, toluene, and xylenes as a total of the fuel increases as the depth of sample increases, and the TPH concentration decreases. This indicates that the heavier fuel components are being trapped and biodegraded in the soils. The highest concentrations appear to be trapped within the silt lenses interbedded in the upper sand alluvium, where the percent of BTEX as a percent of fuel appears to be the lowest. Lateral diffusion through a porous stagnant media such as soil is a slow process. It is apparent from the outlying soil borings, B-3, B-4, and B-5, that none of the petroleum constituents have migrated laterally off site. With the average annual evaporation rate far exceeding the average rainfall, it is unlikely that any petroleum constituent migration w.ill be affected by surface water. It is therefore unlikely that the petroleum hydrocarbons present will affect ground water or soils off site. 5.0 CONCLUSIONS The following conclusions have been reached from the information presented in the Results of Phase I Site Assessment and the Addendum to the Phase I Site Assessment: · Petroleum constituents are present in soil, resulting from the operation of an underground fuel storage facility that exists at the site. · The source of the petroleum constituents (underground storage tanks and associated dispensing system) has been removed. · Two types of petroleum constituents exist. The majority of petroleum constituents in the area where Tanks I through 4 and Tank 9 were located'is in the form of low- volatility petroleum hydrocarbons, i.e., oil and grease. The majority of petroleum e e ADDENDUM TO PHASE I SITE INVESTIGATION Pence Petroleum 920 East Truxtun Avenue; Bakersfield, CA Delta Project No. 40-87:'296 ' Page 11 \-- constituents in the area where Tanks 5 through 8 were located is in the form of volatile \ petroleum hydrocarbons, i.e., gasoline, weathered gasoline, and diesel. · Concentrations of petroleum constituents of low-volatility hydrocarbons range from 7,940 ppm TPH 2 feet below the elevation at which tank bottoms were located to 1,365 ppm TPH 4 feet deeper. These concentrations decrease to less than 100 ppm TPH near the perimeter of the excavated area. · Volatile hydrocarbon concentrations of petroleum constituents range from 1,400 ppm TPH between tanks 2 and 3 at a depth of about 28.5 feet to less than 0.5 ppm TPH at a depth of 40 feet below the ground surface. At depths corresponding to the bottoms of tanks 1, 2, 5, 6, and 7, TPH concentrations ranged from 450 ppm below tank I to less than 0.5 below tank 7. · The amount of volatile petroleum hydrocarbons present is estimated to be about 50 gallons. · The horizontal extent of petroleum constituents is defined by test soil borings B-2 through B-8. · The geologic setting includes dense, fine-grain alluvium that inhibits downward migration of contaminants. I;) · Soil boring B-15 indicates a depth to ground water of approximately 187 feet. The average long-term precipitation is about 5.5 inches per year, and normal evaporation is about 64 inches per year. · A threat to ground water does not exist. 6.0 REMEDIAL ACTION ALTERNATIVES This section will address alternatives of remedial action for the areas containing volatile petroleum hydrocarbons. Three alternatives of remediation are considered practical for the site: · Partial excavation. · In-situ remediation by soil venting. e e ADDENDUM TO PHASE I SITE INVESTIGATION Pence Petroleum 920 East Truxtun Avenue, Bakersfield, CA Delta Project N.o. 40-87-295 Page 12 · ,No action. The- following criteria will be used in evaluating these alte~natives: \- · The potential for further environmental impact. , · The mitigation of present impact to the environment. ! . ThepõtÈmtial environmental impact during remedIation. · Cost benefits. · Performance schedule. 6.1 Partial Excavation The purpose of partial excavation is to remove the petroleum constituent co~taining soils. This process would involve excavation and off-site disposal of soil with petroleum constituent concentrations greater than 100 ppm TPH. The depth of the excavation and the site geology will necessitate an engineered and shored excavation. Excavated soils would be taken to a Class II disposal site. Among the adverse effects of partial excavation would be the impact on local air Quality, including odors and fallout of volatile hydrocarbons, and the safety requirements associated with operating an open pit. The beneficial effect of partial excavation as a remediation alternative is the reduction of petroleum constituents to the point where natural biodegradation would occur in a shorter period of time than if none of the soil was removed. Because of the small volume of petroleum constituents and the depth at which they are located below grade, it is not likely that a partial excavation would substantially reduce the potential for further environmental impact. Table 2 presents a cost estimate for the partial excavation remediation alternative. Estimates are based on costs from representative Delta projects. The estimated cost for partial excavation, disposal, and site restoration is $110,000. Table 3, presents an idealistic estimate for the time needed for remediation by partial excavation. . The estimate is based on time frames for each phase of the project. The total estimated time needed for the partial excavation alternative is 2.5 months. e e ADDENDUM TO PHASE I SITE INVESTIGATION Pence Petroleum 920 Eut Truxtun Avenue, Bakerafield, CA Delta Project No. 40-81-296 Page 13 ' .

Soil venting would reduce the level of volatile hydrocarbon concentrations and mitigate the potential for further impact. Soil venting would not reduce the relatively large concentrations of nonvolatile petroleum hydrocarbons. A typical soil venting system would consist of a vacuum blower, multiple vapor extraction wells, and an emission control system. Because of the small volume of volatile contaminants, and the depth at which the contaminants are located below grade, it is not likely that soil venting would significantly reduce the impact. to the environment. e e ADDENDUM TO PHASE I SITE INVESTIGATION Pence Petroleum 920 East Truxtun Avenue, Bakersfield, CA Delta Project No. 40-87-295 Page 14 J An adverse effect of soil venting is the limitation of land use placed on the owner during the remediation effort. The current property owner, Mr. Charles Pence, has expressed an interest in -- ..-::--=~~elling the site, and the relatively-Iong period of time needed for soil venting may present a hardship to him. 1-- Other adverse effects include adverse impacts to the local air Quality and high energy consumption. Th~ release of volatile hydrocarbons to the atmosphere could be mitigated by an emission control " system. The emission control systems considered for this project include catalytic and/or thermal oxidizers and granular activated carbon (GAC). - Oxidizers would release carbon dioxide at' temperatures exceeding 1,400 degrees Fahrenheit. Neither type of oxidizer is energy-efficient. The costs for a catalytic oxidizer is typically about $48 per day. Supplimentary fuel for a typical thermal oxidizer costs about $8 per day. The cost of GAC absorption may run as high as $7,000 per day at start-up conditions. A beneficial effect of soil venting is the reduction of petroleum constituent levels to the point where natural biodegradation would occur in a shorter period of time. Table 4 presents a cost estimate for in-situ soil venting. Estimates are based on a three-well system using a thermal oxidizer for emission control. Additional costs for system maintenance, air monitoring, and soil monitoring are included. The total cost for soil venting is estimated to be $100,000.

I ,. , I , , , , 6.3 No Action The alternative of no actión involves leaving the present amount of petroleum constituents in the ground and leaving the site unaltered. Because of the small volume of petroleum constituents, the depth at which they are located below grade, and the depth to the water table, it is likely that there will be no further environmental impact. The only costs for the No Action alternative of remediation are those incurred to date. Remediation would be complete upon acceptance of the No Action alternative by all responsible agencies and individuals. 7.0 RECOMMENDATIONS The petroleum constituents in the form of low-volatility petroleum hydrocarbons has been adsorbed by the soils at the site. The remainder of petroleum constituents that are present are volatile petroleum hydrocarbons. The depth to the water table is approximately 187 feet. and ground water recharge from direct precipitation is highly unlikely. Since the source of petroleum constituents has been removed, no ground water is present. and there is little chance for percolation of surface water, it is unlikely that any petroleum constituent migration will occur. .\ ¡ ·1 r-- r- . -- ~ - . --~ . -. -~- I I - [ e e ;' A]2DENDUM TO PHASE I SITE INVESTIGATION Pence Petroleum 9ZCI East Truxtun Avenue, Bakenfield, CA D.Kta Project N~. 40-87-296 Palle 16 The expense required for either excavation of petroleum constituents bearing soils or soil-venting the petroleum constituents impacted zone is not justifiable for the type and amount of petroleum c()ñstinìëntsand- the geologic and hydrologië setting at the site. ,-- -------------..::..::=--==-=-- The site is located in an ·area that has been zoned for industrial uses, and since the petroleum c,onstituent area is approximately 10 feet and more below grade, no impact will be made at the s111rface for most industrial uses.

Ihe soil borings were advanced using a truck-mounted drill rig utilizing hollow-stem- augers. To reduce the chances of cross-contamination between boreholes, all down-hole drilling equipment was cleaned between soil borings. To reduce cross-contamination between samples, the split-barrel sampler was washed in a TSP soap solution and double-rinsed between sampling events. \ ,~il sa1D:pling was done in accordance with ASTM" 1586-84. Using this procedure; a tWo":inch O:D."·..------- split-barrel sampler or a two-inch I.D. California-type sampler is driven into the soil by a 140- pound weight falling 30 inches. After an initial set of six inches, the number of blows required to drive the sampler an additional 12 inches is known as penetration resistance, or the "N" value. The N value is used as an empirical measure of the relative density of cohesion less soils and the consistency of cohesive soils. Upon recovery, a portion of the soil sample was placed into a glass jar and sealed for later screening with a photoionization detector. Another portion of the soil sample was used for classification and description. That part of the soil sample collected in brass tubes within the California-type sampler was stored at approximately 4°C. for transport to the laboratory. 1.2 Soil Classification As the samples were obtained in the field, they were classified by the Delta/geologist in accordance with the Unified Soil Classification ~ystem. Representative portions of the samples were returned to the laboratory for further examination and for verification of the field classification. Logs of the borings indicating the depth and identification of the various strata, the N value, water-level information and pertinent information regarding the method of maintaining and advancing the bore hole were made. ,1.3 Soil-Samole Screenine/hNu Photoionization Detector Method After soil-sample jars were brought to room temperature, the head-space vapors of the soil-sample jars were screened with an hNu photoionization detector equipped with a 10.2 eV lamp calibrated 1to benzene for direct reading in parts per million (ppm). The sample-jar lid was opened and the hNu probe immediately placed within the head space of the jar. The highest observed reading was recorded. ·\ I \ I I I- I , I I [ 1- e e 2.0 ANALYTICAL PROCEDURES All soil samples submitted to the laboratory were analyzed by EPA Method 8240 for benzene, toluene, xylenes, ethylbenzene, and total purgeable petroleum hydrocarbons.

Each sample was collected in a suitable container, preserved correctly for the intended analyses, and stored prior to analysis for no longer than the maximum allowable holding time. Details on the procedure for collection and handling of soil samples used on this project can be found in Section 1.0. 3.2 SamDle Identification and Chain-of-Custodv Procedures Sample identification and chain-of -custody procedures ensure sample integrity and document sample possession from the time of collection to its ultimate disposal. Each sample container submitted for analysis had a label affixed to identify the job number, sampler, date and time of sample collection, and a sample number unique to that sample. This information, in addition to a description of the sample, field measurements made, sampling methodology, names of on-site personnel, and any other pertinent field observations was recorded on the borehole log or in the field records. All samples were analyzed by a California State Certified Laboratory. A chain-of -custody form was used to record possession of the sample from time of collection to its arrival at the laboratory. When the samples were shipped, the person in custody of them relinquished the samples by signing the chain-of-custody form and noting the time of shipment. The sample- control officer at the laboratory verifies sample integrity and confirms that it was collected in the proper container, preserved correctly, and that there is an adequate volume for analysis. The sample was assigned a unique log number for identification throughout analysis and reporting. The log number was recorded on the chain-of-custody form and in the legally-required log book maintained by the laboratory. The sample description, date received, client's name, and any other relevant information was recorded. -- e ¡, 3.3 Analvtical Oualitv Assurance In addition to routine calibration of the analytical instruments with standards and blanks, the analyst is required to run duplicates and spikes on 10 percent of the analyses to insure an added measure of precision and accuracy. Accuracy is also verified through the following: I . ,L --.- U.S. Environmental Protection Agency (EPA) and State certification programs. 1- ( 2: Participation in an inter-laboratory or "round-robin" quality assurance program. :- 3. 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. [ ¡ ¡ 3.4 Miscellaneous Checks of Accuracv Where trace analysis is involved, purity of the solvents, reagents, and vgases employed is of great concern. The laboratory maintains a service contract on all major instrumentation; gas chromatographs, atomic absorption, ion chromatography, and total organic carbon analyzers are all serviced and maintained regularly. The above program is more than sufficient for most needs. Additional quality assurance; such as spikes and duplicates on all analyses, will be provided if requested. i , I' \ -~- r- \ ..- ---.-."------- ------ .~._---,. - - -. ..- .- - .- - - --. ;... þ ~_._-~...._,.--...--~._._~~-.- L _ .~. ,_, .u~_.__ _. __.__----0--_.

Westerheim Client Proiect Number: 83Z-81 Smnmarv of Work Performed Durin2 October. 1987: During the periods, October 20-21 and 26-30, five soil borings were advanced to an approximate depth of 81 feet. Field observations of contamination and soil classification were made. A total of 16 soil samples were sent to Central Coast Analytical Services for laboratory analysis. Upon completion of each soil boring the holes were sealed with a cement sand bentonite grout. No ground water was encountered. Field work for the initia,l site assessment is complete and we are awaiting laboratory results. ~Ial Problems Encountered Durin2 Report Period and Solutions: Originally Lange-Western of Bakersfield was contraCted to perform the drilling operations. Mechanical breakdown of the drill rig and the inability to bring the rig on line in a timely manner facilitated the removal of Layne-Western from the project after completing one soil boring. BSK Associates of Bakersfield was then contracted to complete the job. l!AJ!!. for Additional Work Durin2 November. 1987: Completion of site assessment report with recommendations regarding remedial action.

Environmental Site,Assessment P,mce Petroleum Company Delta Project No. 40-87-295 P:iLge 3 1.0 INTRODUCTION Federated Insurance Company and its insured, Pence Petroleum Company, have authorized Delta Envi- ronmental Consultants, Inc. (Delta) to prepare this work plan describing our proposed environmental site assessment. The environmental assessment will be performed at a former bulk petroleum storage and dispensing facility owned by Pence Petroleum Company located at 920 East Truxton A venue in :Bakersfield, California. The site assessment was requested by' the Kern County Health Department, " :Division of Environmental Health, to determine the extent of petroleum product contamination iden- tified in soil samples taken from beneath underground storage tanks excavated and removed from the :~ite on August 4 and 5, 1987. .1.1 Puroose of Assessment The main objectives for this site assessment will be the following: 1) Evaluate the site geologic characteristics. 2) Evaluate the horizontal and vertical extent of petroleum contamination in'the soil. 3) Assess the overall impact of the contamination on the surrounding environment. 4) Evaluate the need for remedial action. 1.2 Scooe of Work In order to accomplish the above objectives, we propose to perform the following scope of work: I) Review all available data on the site and surrounding area, including a well search within a one-mile radius of the site. 2) Drill a maximum of five standard penetration, hollow stem auger soil borings, collecting soil samples every five feet. . .

The property is located in the NW 1/4 of SW 1/4 of NE 1/4 of SE 1/4 of Section 29, T29S, R38E in Kern County, California (Figure 1). The site elevation is approximately 417' above sea level. The property is owned by Pence Petroleum Company. The site consists of a vacant lot, where the tanks previously existed, with a warehouse building and a house located just east of the warehouse. The site is in an area used mainly for industrial purposes and is bordered on the north by the Santa Fe Railroad" on the south by East Truxton A venue and on the east by Owens Street. Nine underground storage banks previously existed at the site. The approximate locations of the tanks and bulk loading rack are shown on Figure 2. The sizes and former contents of each tank are also shown on Figure 2. . r Environmental Site Assessment Pence Petroleum Company Delta Project No. 40-87-295 Page I; , " "'\ FIGURE 1 SITE LOCATION MAP PENCE PETROLEUM BAKERSFIELD, CALIFORNIA DELTA NO. 40-87-295 .' .-<t1!1ÞIL:'~ 'oo :. ,.===~ \::'. \' .(¡'¡~...

I Scale Feel e e En'Y'ironmental Site Assessment Pence Petroleum Company Delta Project No. 40-87-295 Pa¡¡te 7 2.2 Site Historv The following paragraph presents our interpretation of the site history. If any errors exist, please contact us so they can be corrected. A bulk plant was probably first built at the site in the late 1930's and the underground storage tanks were probably installed at that time. The site was operated by a Becan Oil Jobber until approximately 1951. From 1951 to 1973 the site was operated as a bulk petroleum facility by Douglas Oil Company. Pence Petroleum Company leased the site from Douglas Oil Company from 1973 until 1978 when Pence Petroleum Company purchased the site. The site has been operated as a bulk petroleum storage and dispensing facility for at least the past fifty years. ~:.2.1 Product Loss Information According to Charles Pence, no reported losses of petroleum product have occurred at the site since, ] 973. Prior to ] 973, no records exist documenting any large petroleum releases. ;~.2.2 Tank Testing Data According to Charles Pence, tank number two was tested and reported "tight" in February, ]987. The remaining tanks at the site were never tested, but the tanks were periodically gauged by measuring product levels in the tanks when they were not in use. ~U.3 Reauired Soil Chemical Analvses Soil samples were collected from beneath each end of each underground storage tank during tank I~xcavation. They were collected at depths of two feet and six feet below the bottom of the tank c~xcavation by Dwight Environmental. The soil samples were analyzed by SMC Laboratories of Bakers- field, California. The laboratory test results are attached in Appendix A. The sample 1.0. numbers I~orrespond to Job #447 - Tank Number - East end or West end - depth below bottom of tank. The tank numbers are indicated on Figure 2. e e Environmental Site Assessment PE,nce Petroleum Company D4!lta Project No. 40-87-295 PlIge 8 A review of the sample results indicate the largest concentrations of petroleum hydrocarbons were detec.ted in the soils beneath tanks #2, #3 and #4 immediately adjacent to the warehouse building, and under the south end of tank #5. These results ranged from 100 to 7900 ppm total petroleum hydrocarb- ons. Lesser concentrations ranging from less than 100 to 170 ppm were detected beneath the other storage tanks. ;Z.3 Site Geologv The site is situated over an area of pleistocene non-marine sedimentary deposits which consists of mainly slightly consolidated and dissected fan deposits consisting of granitic sand, silt and clay. (Reference: Geologic Map of California, Bakersfield Sheet.) The soils underlying the excavated tanks were reportedly clays. The land surface in the area locally slopes slightly to the southw~st. The Kern River flows south- west and is located approximately 2.7 miles northwest of the site. 2.3.1. Groundwater and Wells The Kern County Water Agency reports the dept,h to groundwater in the vicinity of the site at approx- imately 220 feet below grade. No water wells exist within a 1,000 foot radius of the site, but four water wells are operated by the California Water Service within a one-mile radius of the site. The reported static water levels in these wells ranged from 208 feet to 257 feet below grade. 3.0 PROPOSED WORK PLAN The background information collected at the Pence Petroleum Company site indicates that groundwater will not be encountered until depths exceeding 200 feet below ground surface. For purposes of this work plan, we will assume that we will only be assessing soil contamination and the geologic charac- teristics of the site that govern contaminant migration. e e Environmental Site Assessment Pen,ce Petroleum Company Deit;a Project No. 40-87-295 Page 9 3.1 Soil Borings We propose to drill five soil borings at the approximate locations illustrated on Figure 3. Initial- ly, we propose to advance the soil borings in the order that they are numbered. The actual locations will be selected in the field by a Delta Geologist or Engineer pending the location of subsurface u1tilities, overhead structures and results of previous borings. The soil borings will be drilled to UJrltil no contamination has been observed for two. consecutive soil samples. Soil samples will be collected at five foot intervals according to the methods described in Section 4.0. .3..2 Soil Sarno Ie Collection and Screening Soil Samples will be collected in brass sleeves with a California Modified Split Spoon sample barrel. Upon recovery of the sampler, the bottom brass tube will be capped, packaged and preserved in a cooler according to accepted EPA procedures. Soil from the middle sleeve will be collected and placed into a sealed glass jar and held until completion of drilling activities. All soil samples' collected in glass jars will be brought to room temperature. The headspace of each jar will be sl:::reened for total organic vapors utilizing a portable photoionization detector. Soil sample slcreening results will be plotted on cross sections showing the stratigraphy of the site. From this information, soil samples will be selected for chemical analysis to best define the horizontal and vertical extent of contamination. ~,.3 Soil Chemical Analyses Based on the results of the soil samples screening, soil samples will be selected for chemical analysis. The soil samples will be analyzed for fuel fingerprint, EDB, BTX, ethyl benzene and TPH by EPA Method 624/8240 (GC/MS SIM). These analyses should characterize the type of petroleum con- tamination (gasoline or diesel fuel) and also give quantitative results.

The soil borings will be advanced using a truck mounted hollow stem auger drill rig. To reduce the chances of cross contamination between boreholes, all down hole drilling will be steam cleaned between each boring. To reduce cross contamination between samples, the split barrel sampler ~ill be washed in a soap solution and double rinsed between each sampling event. Soil sampling will be done in accordance with ASTM 1586-854. Using this procedure, a 2" O.D. split barrel sampler or 2" I.D. California type sampler is driven into the soil by a 140 pound wight falling 30 inches. After an initial set of 6", the number of blows required to drive the sampler an additional 12" is known as the penetration resistance, or the "N" value. The N value is an index of the relative density of cohesionless soils and the consistency of cohesive soils. Upon recovery, a portion of the soil sample will be placed into a glass jar and sealed for later screening with a photo ionization detector and a portion of the soil sample will be used for class- ification. Portions of the soil sample will be collected in brass tubes and stored at approximately 4oCfor transport to the laboratory. We will utilize a C~lifornia State Certified Laboratory to perform the chemical analyses. 4.2 Soil Classification As the samples are obtained in the field, they will be visually and manually classified by the Delta Geologist or Engineer in accordance with ASTM:D 2488-84. Representative portions of the samples may be returned to the laboratory for further examination and for verification of the field class- ification. Logs of the borings indicating the depth and identification of the various strata, the N value, water level information and pertinent information regarding the method of maintaining and advancing the drill hole will be made. 7> e e Environmental Site Assessment Pence Petroleum Company Delta Project No. 40-87-295 Page 12 :4.3 Soil Samole Screening/hNu Photoionization Detector Method The head space vapors of the soil sample jars will be scree~ed with an hNu photoionization detector '~Quipped with a 10.2 eV lamp calibrated for direct reading in ppm volume/volume of benzene. Soil samples collected in glass jars will be brought to room temperature. The sample jar lid will be opened and the hNu probe will be immediately placed within the head space of the jar. The highest :reading observed will be recorded. 5.0 ANALYTICAL PROCEDURES All soil samples submitted to the laboratory will be analyzéd by EP.~ Method 8240 (GC/MS SIM) for Fuel Fingerprint and EDB, BTX, Ethylbenzene and total Purgeable Hydrocarbons. 6.0 QUALITY ASSURANCE PLAN This item describes the field and analytical procedures to be followed throughout the investigation. ~).l General Samole Collection and Handling Procedures Proper collection and handling are essential to ensure, the quality of a sample. Each sample will be c:ollected in a suitable container, preserved correctly for the intended analyses, and stored for analysis for not longer than the maximum allowable holding time. Details ont he sample collection and handling procedures to be used on this project can be found in Section 4.0 for soil samples and groundwater samples. ~;.2 Samole Identification and Chain-of-Custodv Procedures Sample identification and chain-of -custody procedures ensure sample integrity and document 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 ., i e e Environmental Site- Assessment P,ence Petroleum Company Delta Project No. 40-87-295 Page 13 I;ollection, and a sample number unique to that sample. This information, in addition to a descrip- Ition of the sample, field measurements made, sampling methodology, names of on-site personnel, and any other pertinent field observations will be recorded on the borehole log or in the field records. All samples will be analyzed by Central Coast Analytical Services in California. A chain-of-custody form will be used to record possession of the sample from time of collection to its arrival at the laboratory. When the samples are-shipped, the person in custody of them will ¡relinquish the samples by signing the chain-of-custody form and noting the time. The sample control officer at the laboratory will verify sample integrity and confirm that it was collected in the proper container, preserved correctly, and that there is an adequate volume for analysis. ][f these conditions are met, the sample will be assigned a unique log number for identification throughout analysis and reporting. The log number will be recorded on the chain-of -custody form and in the legally required log book Central Coast Analytical Service maintains at the laboratory. The sample description, date received, client's name, and any other relevant information will also be recorded. J5.3 Analvtical Oualitv Assurance ][n addition to routine calibration of the analytical instruments with standards and blanks, the analyst is required to run duplicates and spikes on 10 percent of the analyses to ensure an added measure of precision and accuracy. Accuracy is also verified through the following: . l. U.S. Environmental Protection Agency (EPA) and state certification results. 2. Participation in inter-laboratory or "round-robin" program. 3. 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. <" e e Environmental Site Assessment PE,nce Petroleum Company Dl!lta Project No. 40-87-295 Pnge 14 ~j.4 Miscellaneous Checks of Accuracv Where trace analysis is involved, purity of the solvents, reagents, and gases employed is of great c:oncern. Central Coast Analytical Services maintains a service contract on all major instrumenta- t:ion; gas chromatographs, atomic absorption, ion chromatography and total organic carbon analyzers are all serviced and maintained regularly. The above program is more than sufficient for most needs. Additional quality assurance, such as !¡pikes and duplicates on all analyses, will be provided if requested. 7.0 SITE SAFETY PLAN This plan addresses safety provisions to be employed during the site investigative field 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 (I) the nature of potential materials, and (2) personnel responsibilities. The nature of contaminents encountered at the site should be petroleum products consisting of mainly gasoline and diesel fuels. 7.1 Personnel Resoonsibilities Key personnel directly involved in the investigation who will be responsible for monitoring the execution of safe work practices and the provisions of this plan are (l) the drilling subcontractor project supervisor and (2) the Delta project field manager. These personnel are responsible for knowing the provisions of the plan, communicating plan requirements to workers under their super- vision and to site visitors, and for enforcing the plan. 7.2 Personnel Protection The Øesignated personnel protective equipment is selected to prevent field personnel from exposure to gasoline fuel products that may be present at the site. To prevent direct skin contact, the .. e e Environmental Site .Assessment Pence Petroleum Company Delta Project No. 40-87-295 Page 15 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 or disposable vinyl gloves. 4. Steel toe boots. 5. Goggles or safety glasses (if optional face shield not used on the hard hat). The type of gloves used will be determined by the type of work being performed. Drilling personnel will be required to wear butyl rubber gloves because they will have long-duration contact with the subsurface materials. Delta sampling personnel will wear disposable vinyl gloves when handling any sample. These gloves will be changed between each sample. Personnel protective equipment shall be put on before entering the immediate work area. The sleeves of the coveralls shall 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. Delta will designate a separate area on site for eating and drinking. Smoking will not be allowed at the vicinity of the site except in designated areas. No contact lenses will be worn by field personnel. 8.0 SCHEDULE Delta proposes to begin the work described herein as soon as approval is obtained.
