'"' SEQUOIA PAINT 1.0 INTRODUCTION This report presents the results of a Leaking Underground Fuel' Tarik Site Assessment conducted by i Groundwater Resources Inc. (GRI), a RESNA company, at Sequoia Paint, a retail and wholesale paint ....... business operating at 700 Baker Street in Bakersfield, California (Plate 1). Risks'to groundwater and the surface environment posed by the presence of gasoline in the soil were found to be very low. No ~t' ~' further assessment or remediation is recommended. 2.0 BACKGROUND On January 25, 1990 GRI removed tWo underground' storage tanks, a 4000 gallon gasoline tank and ' .... :~' .... a 200 gallon~waste oil tank, from the Sequoia Paint property at 700 Baker S~eiin Bakersfield. The tanks were reportedly installed in 1982 and remained in service until 1987 at the former WallYTucker automobile dealership. Soil was sampled at a depth of two and six feet beneath each tank, beneath the gasoline dispenser and under the product line halfway between the dispenser and the tank (see Plot Plan, Plate 2). The dispenser was located in a closet at the west side of the main building on the site which necessitated using a hand auger to obtain samples beneath the concrete floor of the structure. All samples were analyzed by BC Laboratories in Bakersfield. Those associated with the gasoline system were tested for BTXE and TPH (gasoline). No hydrocarbons were detected except in the sample from six feet beneath the dispenser which contained 32.55 ppm total xylenes and 935 ppm TPH (gasoline). The waste oil samples were analyzed for TPH (oil and grease), total lead and total halogenated hydrocarbons (TOX). No halogenated hydrocarbons and.background levels of total lead and TPH (oil and grease) were reported. A site assessment of the contamination indicated by the six foot dispenser sample was required by the Kern County Department of Environmental Health Services. Two attempts were made to determine the vertical extent of the gasoline plume under the dispenser using a hand auger. On March 9, 1990 GRI obtained samples at a depth of 8, 11 and 14 feet, all of which contained significant leVels of gasoline constituents. On July 25th Duane R. Smith and Associates augered a hole to 25 feet which was later deepened to 35 feet and collected samples at 20, 25, 30 and 35 feet. Low to moderate concentrations of gasoline constituents were'present in these samples. The results for all sampling efforts at the dispenser are listed below in Table 1.

The contamination extended.beyond-the reaeh..of a hand auger and a truck mounted auger drilling rig .... I was required to complete the characterization of.this site. 3.0 PROCEDURES A hollow stem auger drilling rig, owned by RESNA Industries, was used to drill two borings, both' directed at a 10 degree angle beneath the building. Cores Were retrieved at five foot intervals with a California split-spoon sampler. A representative sample of each core was sealed in a brass sleeve with duct-taped teflon-lined plastic caps and chilled on ice. The other sections of each core were described lithologically, checked for pe_~oleum odors and screened with a photoionization detector (PID) for volatile hydrocarbons. Upon completion of drilling operations, the sealed cores were transported to SMC Laboratory in Bakersfield under a chain of custody for chemical analysis. Selected samples were analyzed for BTXE and TPH (gasoline). Cores retrieved at depths and locations previously sampled with hand augers were not chemically analyzed to avoid duplicating earlier results. Augers were decontaminated by high pressUre steam cleaning between borings to prevent cross- contamination. Both borings were abandoned by filling with a neat cement slurry emplaced by the tremie method. 4.0 FINDINGS 4.1 Borings Boring S-1 (Plate 5) was placed three feet from the clOset which formerly housed the fuel dispenser. The hole was drilled at a ten degree angle beneath that room under the the building to a depth of 60 feet (see the Plot Plan, Plate 2 and the Cross Section, Plate 4). The boring essentially twinned, to a depth of 35 feet, the hand-augered holes completed earlier; Moderate to strong gasoline odors and elevated PID readings .........................................

The lab reported minute quantities of gasoline constituents at 45 and 55 feet. Hydrocarbons were absent at 50 feet and at 60 feet only xylenes at minimum detection levels (.005 to .007 ppm) were present. Laboratory results for the samples from Boring S-1 are listed below: ~ TABLE 2 ANALYTICAL RESULTS FOR BORING S-1 (in ppm) Depth Benzene Toluene Ethylbenzene Total Xylenes TPH (gasoline) 40 Fl' 20 48 100 430 3500 45 FT .012 .058 .023 .215 1.8 50 FT ND ND ND ND ND 55 FT ND .018 .011 .095 1.2 60 Er ND ND ND .012 ND Boring S-2 (Plate 6) was drilled at a 10 degree angle under the showroom building at a location 12 feet north of Boring S-1. The hole was advanced to 45 feet, penetrating the equivalent interval in which contamination was found in S-1. A slight petroleum odor was noted at 25 feet, but no hydrocarbons were 'detected in the core from this, depth or in samples from 20, 35 and 45 feet which were also analyzed (Appendix A). 4.2 Geology and Hydrogeology The Sequoia Paint property lies in a residential and business district in East Bakersfield within two and one-half miles of the Kern River to the north. In the shallow subsurface the area is underlain by unconsolidated ailuviai sand-rich sediments deposited by the Kern River during recent geologic time1. The borings encountered eight to nine feet of silts and silty sands at the surface, underlain by a i . sequence of predominantly coarse sands with occasional gravelly.intervals which i persisted to about 35 feet where a transition to mostly fine grained, silty and clayey ........ :., ...... ......... sandsoccurred._~This lithology was still present at 60 feet, the lowest level, reached .... (See Boring Logs and Cross Sections Plates 3-6). The change from highly porous JANUARY' 22, 1991/Page 3 GROUNDWATER RESOURCES INC. SEQUOIA PAINT sands to less permeable material corresponds with the base of significant contami- nation indicating that stratigraphy may have played a role in limiting downward migration of contaminants. · -.. <'~:'::"According:to' maps'published by the Kern .County-Water 'Agency2' 'depth 'to .... ::~' groundwater of the regional unconfined aquifer is approximately 160 feet. Shallow perched groundwater of limited areal extent also occurs in the vicinity where clay layers interrupt the downward movement of water. The most recent map for the Summer of 1989 shows the northern lobe of regional perched water to be situated south of Bakersfield. No groundwater was encountered in this assessment DISCUSSION As a result of the various assessment efforts at the Sequoia Paint site, the vertical and lateral extent. of soil contamination has been delineated and threats to the surface environment as well as groundwater resources can be evaluated. The vertical extent of the plume is depicted on the Cross Sections (Plate 3 and 4) and the maximum lateral dimension of the plume is shown on the Plot Plan (Plate 2). The interpretations assume the plume to be essentially symmetrical and centered on the dispenser location. 5.i Extent of Gasoline Contamination in the Soil Boring S-1 and the hand-augered holes were centered as closely as possible to the dispenser point of origin of the gasoline leak in order to determine the vertical extent of the gasoline plume. Moderate levels of gasoline contamination are present between 6 and 40 feet. TPH (gasoline) concentrations range between 935 and 4100 ppm from 6 and 14 feet and 3500 ppm is present at 40 feet; at other horizons, values of several hundred Ppm are the norm. BTXE concentrations are very low or absent except at the 40 foot inte~wal. The base of the plume occurs just below 40 feet. Only. trace amounts of gasoline constituents are detectable below that depth. Boring S-2 was drilled 12 feet from S-1 to gain information on the lateral spread of the gasoline plume with depth. Minimal horizontal migration was anticipated because of the porous nature of sediments which characterize the area. No gasoline Constituents were detected by the lab in the samples tested. The slight odor detected at 25 feet indicates that this boring was 'at the outer margins of the plume and that its maximum lateral extent is less than 12 feet. 5.2 Groundwater Risk Groundwater occurs at approximately 160 feet in the vicinity of the site. It is not considered to be at risk. The source of the. gasoline contamination has been removed. The base of the plume at 40 feet lies 120 feet above the water table and ................. as. discuss~d-~i-e~iously, theclayey int~iS/iil'~Which .develOPs 'at 55 feet' like]y'' impeded downward movement of the hydrocarbons.

The assessment shows the affected area to be half under the Sequoia Paint building and half under the ,~. .adjoining driveway. Presently a strip of soil is exposed along the side of the i building where the piping connecting the dispenser and fuel tank was removed. When this section is paved the entire outside portion of the contaminated area will ' be isolated from the surface. The concrete floor of the building will effectively prevent most vapors from entering the building. The~hole in th_._e floor through which the i in ched the dispenser must be sealed. Another factor which further reduces the risks associated with this site is the very low concentrations of BTXE, the constituents of fuel which engender the most concern, particularly benzene,' a proven carcinOgen. These components were either not detected or they were present at very low concentrations above a depth of 40 feet. The._e~4.0,.foot Lam~ple was the onl~ted concentrations of these substances w'a~-f~und (see Table 1 and 2). ~ ~'~ An effort was made to evaluate the health risks due to exposure to benzene volatilizing from the soil and entering the Sequoia Paint building. Outside exposure to vapors was considered to be virtually nil. BenZene was used because it is the only identified carcinogen present. The highest concentration, 20 ppm, occurs at 40 feet and this value and depth v0ere used in the calculations. Laboratory determined values for soil properties at the site were not available. Assuming a sediment matrix consisting primarily of unconsolidated medium to coarse sand with a low moisture content, the following parameters were estimated: Porosity .35 Bulk Density 2.0 ........................................ MiSisture 'Content ....... ~ 15 ...................... [ANUARY 22, 1991/Page 5 GROUNDWATER RESOURCES INC. SEQUOIA PAINT · The approach used for the risk assessment is based in part on the methods and logic presented in The California Site Mitigation Decision Tree Manual4, but was pri- marily modeled after a report submitted to thc Orange County Health Care Agency ..... by ChemRisk entitled Screening Level .Risk Assessment For Benzene, Toluene, Xylene, And Ethylbenzene In Indoor Air At The Former Shell Station Site At Costa Mesa5. This document was made available to GRI by the Agency as an example of . a state of the art health assessment. The steps followed and.the conclusions of this study are outlined below. A more complete discussion and the calculations are included in Appendix C. The first step in the risk evaluation process is the calculation of the steady state flux of benzene through the soil matrix assuming a non-diminishing source at some distance below the ground level. This determination requires the knowledge of benzene's coefficients of diffusion in air and through the soil as well as the vapor phase concentration of the substance at the source. Knowing the vapor phase flux through the soil, the volume of air within the building, a ventilation rate and assuming a leakage rate through the structure's foundation, a benzene vapor concentration within the building can be predicted. Then, taking a._~..orse~ase ~cenari~o of a person working their entire 45 year occupational lifetime at the business, a lifetime average daily dose (LADD) received by inhalation can be derived.' Values of indoor vapor concentrations and LADDs can then be compared to regulatory guidelines to evaluate degree of exposure and risks. In this instance, the indoor concentration of benzene was calculated to be 2~0x10-7 mg/m~3. The DHS , Applied Action Level for benzene in ambient air is ~.2x~10~m. 3. The air concentration for lifetime cancer risk due to benzene exp6~ure 6.6x10-4 mg/m3 can also be used (DHS E-05 excess lifetime cancer risk level for benzene). Based on a individual who worked at the site for 45 years, a LADD of 1.25x10-8mg/kg-day was calculated. This result can be compared to 3.0x10'4 mg/kg-day which is considered to result in a 1 and 100,000 excess cancer risk under CDHS Proposition 65 guidelines. In all cases, calculated values are well below established guidelines. The potential for carcinogenic health effects can also be evaluated by multiplying the lifetime benzene exposure (inhaled volume times concentration) with an "adjusted potency factor' (USEPA)6 to derive a carcinogenic risk associated with a specific exposure to benzene. In general, regulatory agencies have found that a risk in excess of 1 in 1 million is acceptable. In some instances risks of 1 in 100,000 are used in setting environment standards. At Sequoia Paint a risk of 6.0x10'10 was derived, ~well in-excess' of the 1 in 1;000,000 criteria. - .. JANUARY 22, 1991/Page 6 GROUNDWATER RESOURCES INC. SEQUOIA PAINT In conclusion, based on this risk assessment exercise, no significant health hazards exist at the Sequoia Paint site. "6.0 --' REcoMMEND.~Ti0NS Based on the information obtained and analyzed during the site assessment process, risks to groundwater resources and the public health are considered to be very low. ,btoX~er as~essment~or .~ ~_e_ site i_~s deemed neees__~.L~ and site closure is recommended. In addition to the "no action" alternative, the excavation and vapor e~ re~nedial action option~ are discussed below. 6.1 No Action Under the "no action" alternative, no further assessment or remediafion to mitigate the contamination characterized in this study will be required. The.gasoline constituents will be allowed to remain in the soil to slowly dissipate and degrade with~ time. This course of action is considered justified by the demonstrated very low risks'to the groundwater resource and to the people employed in the building partially overlying the site. Alternative approaches are either not feasible or are too costly. To insure isolation of the contaminated mass from the surface, the driveway will have to be completely paved and the piping passageway through the building flooring must be sealed. 6.2 VaPor Extraction Gasoline contaminated soils have been successfully cleansed using vapor extraction technology. In this approach vadose weils screened through the contaminated soil interval are installed in the plume. They are attached at the .surface to a blower or air pump. A vacuum is created and soil gas is drawn to the well bore carrying along gasoline volatiles which are stripped from the soil. At thesurface hydrocarbons are thermally destroyed in an internal combustion engine, catalytic oxidizer or they are adsorbed in carbon filters. This method should work satisfactorily at this site because of the porous nature of the affected soils. Because of its limited, siz. e, one well centered in the gasoline plume may be sufficient to effect complete cleanup in a matter of several months. The construction of one vadose well will cost $3000. A' tyPical treatment system using an engine and catalytic converter to bum the liberated volafiles can be leased for $8000 per month including fuel and maintenance costs. Installation and startup fees add $2000. Carbon filters are used where concentration of the hydrocarbons are low due to high carbon replacement costs. Installation of a system using four ................ ~ ...... carbon canisters will cost about$25,000.00. Addition costs will be incurred for~ studies required to design an appropriate system. JANUARY 22, 1991/Page 7 GROUNDWATER RESOURCES INC. SEQUOIA PAINT The vapor extraction alternative is not recommended in this instance due to its high costs relative to the low environmental risks posed by this situation. 6.3 Excavation ..... : -: ':'-' Excax;ati°n-~f~0~thmifiated soils is ii' 9iiible option When the material ig' to earth moving equipment 'and the plume does not extend much beyond 20 feet in depth.

This rate is influenced by such factors as the degree of partitioning of benzene between vapor, soluble and non- aqueous phases, the rate and degree of movement of the various phases throUgh the.soft, soft properties, and' environmental factOrs'-such as' temperature, moisture and surface conditions. The general approach used, is to take the dominant transport mechanism, in this case vapor diffusion, and model the process. The model used is based on one developed to predict emissions from landfills by Thibodeaux and Hwang7. It assumes steady-state fluxes for a non-diminishing source at a specific depth below the ground ~urface. The applicable equation is: ~ CvDs F- H Where: F-- Steady-state vapor flux through a soil-matrix, from a non- diminishing source - mg/m2'-day Cv = Vapor phase concentration of benzene at the source - mg/m3 Ds = ~ Vapor phase diffusion coefficient through soil - m2/day H= depth below ground surface of the contamination - 40 ft (12.19m) xPMw .Cv- RT Where: x = Mole fraction of benzene in the free liquid hydrocarbon phase. It is assumed to be approximately equal to the weight fraction of benzene in the residual 20 ppm benzene 4100 ppm TPH The TPH value is the highest concentration encountered at the site. . P = Pure component vapor pressure (arm) at temperature T - (0.10 atm) T = Temperature (o K) - 298 OK Mw = Molecular weight of benzene - mg/mole - 78000 R = Universal gas constant - 8.21x10-5 m3-amx/mole-OK xPMw 4~00(0'10)(78000) Cv- RT - (8.21x10-5)(298), 1555mg/m3 (Oa)(a3.33). Ds = T2 , a = E-MB Equation. derived from Millington-Quirk8 Da = diffusion coefficient of benzene in air - 0.32 m2/hr = 0.77 m2/day.

Benzene reaching the surface under the structure may enter the building through openings in the floor, for example, cracks, joints and loose fitting pipes. The ratio of leakage to total floor area in the average California home is 2-10cm/m2 of floor area (Grimsrud et al)10. Commercial buildings built on doncrete slabs would experience less leakage then residences with crawl spaces, therefore, the lower range value of 2cm/m2 is used in this analysis; The ventilation rate for the building is based on the studies of Fisk et allL They estimated that the average air exchange rate for residences at 0.5-0.9 air changes per hour. The most conservative low end value 0.5 is used. A retail business with numerous customers entering and leaving and equipped with modem ventilation systems would experience much higher exchange rates. The concentration of benzene in the indoor air is predicted by the equation: FA Q,- Q Where: Cb = Indoor air concentration of benzene due to volatilization from the .. soil- mgtm3 F= vapor flux through'openings in the foundation - mg/m2-hr· 3.72x.10-2mg/m2-day x 1 day/24hr = 1.55x10-3 mg/m2-hr A = Leakage area = 0.0002m2openings/m2 floor area x 372 m2 floor ................................. area = .0744 m2 Q = ~ Ventilation rate in building - m3far = 0.5 exchange rate/hr x 1116 m3 building vOlume =558m3/hr Cb = . 558 .= 2.0xi0-7 mg/m3 RISK BY EXPOSURE tn order to estimate the health risks associated with~exposure to benzene,-.a very conservative approach was used based on a individual working at the company for an entire occupational lifetime of 45 .years, 5 days a week and 50 weeks a year with an inhalation rate of 10 m3faour. .:'rotal lifetime inhaled volume ' 1.13xi05 m3 Average daily volume = 4.4 m3/day '~xposure is the product of contaminant concentration (Cb) and air volume breathed calculated by the following equation: LADD--- Bw LADD = Lifetime average daily dose - mg/kg-day Cb = concentration of benzene in air = 2.0x10'7 mg/m3 A = Inhalation bioavailability (fraction of benzene inhaled) 100% B = average daily volume inhaled = 4.4 m3/day Bw = Body weight = 70 kg (2.0x10'7)(1)(4.4) LADD = · '70 - 1.25x10-8 rog~kg-day The carcinogenic risk associated with a specific exposure can be estimated by the fonowing: R=P'E' Where: R = Risk associated with a specific exposure P'= Benzene adjusted pOtency factor [mg/lifetime exposure]-1 = 1.63x10-8 USEPA6 - derived from epidemiological, studies on cancer induced E = Exposure = inhaled volume m3/lifetime exposure x concentration R = (1.63xlO'8)(1.13xlOS)(2.0xlO'7)= 6.0x10'10 Environmemal Health Ser~ces Department RANDALL L.

Smith and Associates for the above-referenced site. Duane R. Smith and Associates proposes three hand auger test holes to determine depth and lateral extent of the site's contaminant plume~ Our Department is agreeable to the proposed hand auger test holes #1, #2, and #3 at the dispenser area. However, an additional slant augering will be required to explore the possibility of contaminant migration beneath the existing .showroom and office building. Previous hand augering 'on March 9, 1990, performed by Groundwater'Resources, Inc. showed soil consistencies to be silty sand progressing to a gravely coarse sand. At the 14 foot depth hand augering became increasingly difficult. In view of this, it may not be possible to adequately define' the contaminant plume by hand augering. Additional boring techniques may be required. Jim Elder Page Two May 31, 1990 Please have your environmental contractor forward to this office an additional plot plan depicting the required slant auger test hole. ~ Upon receipt of the addendum information, our office will continue the workplan review.

(GRI) removed ~wo underground fuel tanks from the referenced pcoper%y and conducted soil sampling as required for the preliminary .assessment. The samples were analyzed by BC Laboratories of Bakersfield for several fuel constituents. No evidence of contamination was found except for the sample taken six feet beneath the dispenser which contained 32.55 ppm total xy]enes and 935 ppm TPH (gasoline). These results were reported to the Department on February 12, 1990. At the request of Hr. Jim Elder, owner of Sequoia Paint and with the concurrence of your Department, GRI, on the 9%h of March, obtained additional soil samD]eS beneath the disoenser using a hand auger. SamD]es were collected at a depth of~~ee%. At sampling points, %he auger bit was reD]aced by a clean brass sampling.tube and a slide hammer 'was used to drive the tube into the soil. The tubes were then sea]ed and chilled for transport to BC Laboratories '~nder a chain of custody document. Analysis for BTXE and TPH (gasoline) were requested. While augering petroleum odors were noted between 5 and.14 feet. Hydrocarbon were found by the lab in all samD]es. No benzene was detected as in the previous six foot sample, but toluene, ethy]benzene and higher concentration of total xy]enes were present. TPH (gasoline) levels were also higher, ranging from 1700 to 4100 ppm. The complete lab results are attached. If you require further'information,, please call (805)835-7700.

(GRI) removed the · following underground tanks from the referenced property: One 4,000 Gallon Unleaded Tank One 200 Gallon Waste Oil Tank The tanks were decontaminated on site using a high pressure steam cleaner and inerted with dry ice. Rinsate was disposed of at Gibson Oil and Refining in Bakersfield under manifest ~88524447. The tanks were removed to American 'Metal Recycling, Inc. in Ontario, California. Soil samples were retrieved under Kern' County Department of Health. Services direction (see plot plan for locations). The gasoline tank was sampled one third.of the way in from each end at two and s.ix feet beneath the tank bottom. Samples were also obtained at two and six feet beneath the fuel dispenser and under the piping half way between the tank and dispenser. A two and six foot sample were taken from beneath the center of the waste oil tank. All samples were analyzed by B.C. Laboratories in Bakersfield. Those associated with the gasoline tank were anlayzed for BTXE and TPH (gasoline). 'No hydrocarbons were detected except in the sample taken six feet under the dispenser which contained 32.55 ppm,total xylene and 935 ppm TPH. The waste oil sample' was tested for total lead,'total halogenated hydrocarbons (TOX) and oil and grease, as follows: TOTAL LEAD.

Bakersfield, California. The-site is situated in Section 29, · T.29S., R.28E.., M.D.B.&'M. (see Figure 1). The site is used for the distribution of paint and related products. The general area is commercial and residential~ The facility permit number is 150075. The Sequoia Paint Company moved their showroom facilities to the property during the past several months. Mr. Jim Elder of Sequoia Paint researched past building permits and reports that Wally Tucker Datsun constructed the current buildings in 1966. Wally Tucker Datsun occupied the site from about 1952 to 1985. The property was vacant after 1985. The property reportedly was vacant prior to 1952 except for a small fast food outlet which may have occupied the site in the 1940s. Two underground storage tanks were removed from the property on January 25, 1990 by Groundwater Resources, Inc. (GRI). A 4,000 gallon unleaded gasoline tank and a 200 gallon waste oil tank were situated on the property approximately as~shown on Figure 2.

The tanks were made of steel and reportedly were installed in 1982~ and removed from service in 1985. Figure 3 shows a more extensive~ and.more detailed map of the site' · There are no known rePorts of discrepancies or reportable variations in inventory monitoring, failed tightness tests, repairs to tanks or piping, or past leaks. According to the Geol°gic.Map of California, Bakersfield Sheet, the sediments underlying the site consist of Quaternary fan deposits comprised of sediments deposited from streams emerging from highlands surrounding the Great Valley. In general, these deposits consist of unconsolidated, poorly sorted sitt, sand, and gravel. According to the General Soil MaP of Kern County, published by the Soil Conservation Service, U.S.D.A., the site is underlain by soiis of the Delano association. In general, "t'his association consists of well drained moderately fine textured soils developed in sandy granitic alluvium. Based on the 1988 Report on Water Conditions, Improvement District No. 4, published by the Kern County Water Agency, the depth to groundwater beneath the site is approximately 220 feet. No perched groundwater is known to exist beneath the site. SITE MAP .- SEQUOIA PAINT 700 BAKER STREET BAKERSFIELD . CALIFORNIA CANOPy --CUffs NOTES: 1.

Samples associated with the gasoline tank were analyzed for T.P.H. gasoline and B.T.X.& E. Samples associated with the waste oil tank were analyzed for T.O.X., total. lead, and oil and grease. The sample'locations are shown on Figure 2. Sample S-D-2 was collected at a depth of 2 feet beneath the dispenser. No T.P.H. gasoline or B.T.X.& E. were detected in this sample. Sample S-D-6 was collected at a depth of 6 feet beneath the dispenser. This sample reportedly contained 935 ppm T.P.H. gasoline and moderate levels of xylene. Samples S-P-2 and S-P-6 were collected at depths of 2 feet-and 6 feet beneath the piping, respectively." No T.P.H. gasoline or B.T.X.& E. were detected in these samples.

N6T:,o.x. was detected'in either sample. These results indicate no significant contaminatiOn beneath either tank °r beneath the gasoline piping. However, significant gasoline contamination is indicated beneath the former dispenser location. Subsequent to receiving the Preliminary Site Assessment results, one hand auger boring was drilled by GRI at the former dispenser location to a depth of 14 feet. Soil samples were collected at depths of 8, 11, and 14 feet. Details of the sample methodology are not known. The 8 foot sample reportedly contained 4,100 ppm T.P.H. gasoline and moderate levels of B.T.X.& E. The 11 foot sample reportedly contained 1,700 ppm T.P.H. gasoline and moderate levels of B.T.X.& E. The 14 foot sample reportedly contained 1,900 ppm T.P.H. gasoline.and moderate levels of B.'T.X.& E. The analytical results and chain of custody record from this test hole are included in Appendix A, pages A-13 through A-17. SOIL SAMPLING PLAN · Phase I Since the tanks and plumbing were relatively new and were in use for only three years, we feel there is a good chance that the contamination is not very 'extensive. For this and o~her reasons, ......................... ' ' ' " er test _~ The other reasons include difficult drilling rig access .(see Figure 3) and the proven ability to drill with a hand auger at this site. Furthermore, recent drilling experience nearby suggests that the sediments to a depth of 35 or '40 feet can be readily penetrated. Three soil borings are proposed to assess the vertical and horizontal extent and the' degree of contamination at the former dispenser. location. Figure 4 shows the locations 'of the three test holes. Test Hole No. 1 is .located near the presumed center of the contamination. The intent of this test hole is to provide data necessary to determine the vertical extent of the contaminant .plume. The other tWo test holes are perimeter borings to provide data necessary to ~determine the horizontal extent of the contaminant plume. The exact locations of Test Hole Nos. 2 and 3 may vary slightly depending on the results of Test Hole No. 1. Test Hole lOcations 'at the site are limited because ~f structures. The borings will be drilled until the maximum vertical extent of ~ontami~ti°n 'is 'exceeded or "to ~e maximum p~et~able depth.

SMITH & ASSOCIATES -- MAY 1990 Figure 4 it is determined from T.H. No. 1 that the vertical extent of contamination cannot be exceeded with a hand, auger, Phase II of this work plan'will be'implemented. ..... Soil samples will be collected at 5 foot intervals.. Since a boring has already been sampled at a depth of 14 feet in the immediate 'vicinity of T.H. No. 1, samples will be collected from T.H. No. 1 starting at a depth of 20 feet. Sample collection will start at'a depth of 5 feet in T.H. Nos. 2 and 3. The borings will be drilled with a 2 inch diameter hand auger using 4 and 5 foot extensions. Soil samples will' be collected with a hand driven core sampler. The core sampler contains one 2 inch diameter by 2 or 6 inch long brass liner. After advancing the test hole to the proper sample depth with the hand auger, the hand auger will be carefully removed and the core sampler inserted into the boring. The core sampler will then'be driven into the soil using a hand actuated impact hammer. The brass liner will then be removed from the sampler and immediately coVered with Teflon seals and polyethylene caps and taped shut with duct tape. Each brass liner, after being sealed and taped, will be labeled and placed in a polyethylene sample bag which will then be. labeled and sealed. Each sample will be placed in an ice chest and retained in a chilled state on'blue ice for transport ~o B. C. Laboratories. The drive sampler will be thoroughly scrubbed, washed, and rinsed between sample collections. 6 Selected soil' samples will be submitted to B. C. Laboratories and analyzed for T.P.H. gasoline and B.T.X.& E. The quality assurance and quality control of the laboratory is available from B..C. Laboratories on request.

In addition to the headspace readings, hydrocarbon odors, if 9resent, will be. noted. The test holes will be backfJlled with a cement-sand slurry mix. Contaminated drill cuttings, as identified by field screening, will be placed in DOT drums for future treatment or disposal. Phase II If it is determined that the methodology of Phase I cannot· provide adequate data to characterize the contamination, Phase II will be implemented. Phase II will consist of the same three boring locations as Phase I, but the drilling methodology will be different. The borings will be drilled to a maximum depth of 50 feet each. If field screening indicates that the vertical extent of contamination is less'than 50 feet, the boring depths will be decreased accordingly. 7 If the vertic-al extent of contamination is found to be significantly greater than 50 feet, additional'borings will be proposed in a Phase II work plan. Based on the judgement of the on-site geologist, the borings proposed herein may be drilled slightly deeper than 50 feet-'if ~it '-appears'that the~ v~rtical--~'~~ only slightly greater than 50. feet. Groundwater should not'be encountered in any of these borings and will not be considered in th~s work plan. soil samples will 'be collected every 5 feet starting at a depth of 5 feet except at T.H. No. 1 where sampling will begin at a depth of 20 feet. Selected soil samples will be submitted for analyses. The samples will be analyzed for T.P.H. gasoline and B.T.X.& E. by B. C. Laboratories. The quality assurance and quality control of the laboratory is available from B. C. Laboratories on request. Chain of custody records documenting sample handling will be included. Soil samples will be collected using a split-spoon sampler driven into the soil utilizing a truck-mounted continuous flight hollow stem auger rig (Mobile Drill B-53). The split-spoon sampler contains three two and one-half inches diameter by six inches long ~rass tubes. The sampler will be driven through the proper sampling interval after the hole is drilled with the hollow stem auger. The sampler will then be removed from the drilling equipment and the brass tubes removed from the sampler. 8 The ends of. ~ne tube from each sample depth will be covered with Teflon seals and polyethylene caps and then sealed with duct tape.

D.Dring. alloperations-that might release-airborne-vaporS,~"an Hn~ PID meter will be used to monitor vapors in the breathing zone of workers. If there are significant.readings for a sustained period, the drilling operations will be suspended and the wdrk reevaluated. Recognition of hazards, whether it be from instrument readings, 'odor, irritation, visibility, headache, dizziness, or fatigue, is important, but it is equally important to take appropriate action when a hazard is recognized. If the problem cannot be promptly corrected, we will back off from the exposure source and obtain assistance to solve the problem. Work practices and engineering controls will be devised to minimize potential exposures.. For example, we will work upwind of any potential exposure source. Air-purifying respirators with combination organic vapor/acid, gas/dust, fume, and mist cartridges will be on location. These will be worn when Hnu readings persist above significant levels in the breathing zone. If there is eye irritation, full-face respirators will be used. Tyvek coveralls will be worn as necessary to avoid skin contact. with contaminated soils. Chemical resistant gloves and boots will also be worn as necessary to avoi~ hand and foot contact with contaminants.

The potential hazards involved in the job will be reviewed with all personnel including subcontractors working on site. Prior to commencement of work, emergency evacuation routes will be established. A "safe zone" location will be established taking into account weather conditions, site activities, and other factors, as necessary. Duane R. Smith and Associates personnel will coordinate activities in an emergency situation. Arrangement will be made for transportation to a hospital in the event of an accident or exposure to hazardous materials that produce organic symptoms in the exposed party.

The site is situated in Section 29, T.~gs., R.28E., M.D.B. & M. (see Figure 1). The site is used for the dist ibu:tio f:-'paiht'~'~nd '~eT~'~'d~"~'6:~:6'ts'~ ........ Th~he~'~'~:~ is commercial and residential. The facility permit number is 150075. The Sequoia Paint Company moved their showroom facilities to the property early in 1990. Mr. Jim Elder of Sequoia Paint re- searched past building permits and reports that Wally Tucker Datsun constructed the current building in 1966. Wally Tucker Datsun occupied the site from about 1952 to 1985. The property was vacant after 1985. The property reportedly was vacant prior to 1952 except for a small fast food outlet which may have occupied the site in the 1940s. Two underground storage tanks were removed from the property on January 2'5, 1990 by Groundwater Resources, Inc. (GRI). A 4,000 gallo~ unleaded gasoline tank and a 200 gallon waste oil tank . were situated on the property approximately as shown on Figure 2.

SITE GEOLOGY According to the Geologic Map of California, Bakersfield Sheet, the sediments underlying the site consist of Quaternary fan deposits comprised of sediments dePosited, from streams emerging from highlands surrounding'the Great Valley. In general, these deposits consist of unconsolidated, poorly sorted silt, sand, and* gravel. According to the General Soil Map of Kern County, published by the Soil Conservation Service, U.S.D.A., the site is underlain by soils of the Delano association. In general, "this association consists of well drained moderatelY fine textured soils developed in sandy granitic alluvium.

SMITH & ASSOCIATES -- OCTOBER 1990 Figure 5 Test Hole NO2 1 was drilled with a 2 inch diameter hand auger using Z, 4., and § foot extensions. Soil samples were collected with a hand driven core sampler. Depending on sampling condi- tions, the core sampler contained one or more 2 inch diameter by -2 :'~'Ch-10ng brass liners. After-advancing the test hole to the proper sample depth with the hand auger, the hand auger was carefully removed and the core sampler inserted into the boring. The core sampler was t~hen driven into the soil using a hand ~-='.~t~a~="i~-hammer. The bra~s liner was then removed from the sampler and immediately covered with Teflon seals and poly- ethylene caps and taped shut with duct tape. Each brass liner, after being sealed and taped, was labeled and placed in a poly- ethylene sample b~g w.hich was then labeled and sealed. Each . Sample was placed in an ice chest and retained in a chilled state on blue ice for transport to SMC Laboratory. The drive sampler was thoroughly scrubbed, washed, and rinsed between sample collections. Four soil samples from T.H. No. 1 were submitted for chemical analyses. The samples were analyzed for T.P.H. g~soline and B.T,X.& E. by SMC Laboratory in Bakersfield. . The analytical ~methods utilized by SMC Laboratory are listed on the laboratory reports included in Appendix B.

In addition to the headspace readings'- ~h~dr0C-"rb6h~'~ 0dbms-,~ 'if de~e~t~d, were noted. Field screening results are shown on Figure 4. Drill cuttings were placed in a DOT drum and retained on-site.~J Soil samples were c~iiec from T.H. No. ! at depths of 20, 25, 30~ and 35 feet.. Since a hand auger boring' had already been . .. .. sampled at depths of 8, 11~ and 14 feet in the immediate vicinity of T.H. No. 1~ samples were.not collected above 20 feet. The delay in advancing this test hole to 35 feet was' due to sampling difficulties at 25 feet. A core sampler with a built-in sand catch was ultimately used to collect samples at 25, 30, and 35 feet. The 20 foot sample from T.H. No. 1 reportedly contained 15 ppm T.P.H. gasoline and traces of ethylbenzene, xyl'enes, and isoprop- ylbenzene. The 25 foot sample from T.H. No. 1 reportedly con- tained 250 ppm T.P.H. gasoline, traces of toluene, and low levels of xylenes. The 30 foot-sample from T.H. No. 1 reportedly contained 520 ppm T.P.H. gasoline and moderate levels of B.T.X.& E. The 35 foot sample from T.H.

Supplemental Work Plan SinCe it was determined that hand augering cannot provide ade- . quate data to characterize the contamination,.Phase II will be implemented. Phase II will consist of the same boring locations· as Phase I (see Figure 5), but the drilling methodology will be different. Test Hole No. 4 will be slant drilled at an angle of 20' from vertical under the building as shown on Figure 5. Test Hole No. 3 may be omitted if the lateral extent of contamination can be defined by T.H. No. The borings will be drilled to a maximum depth of 75 feet each. If field screening indicates'that the vertical extent of contami- nation is less than 75 feet, the boring depths will be decreased accordingly. If the vertical extent of contamination is found to be significantly greater than 75 feet, additional borings, will be · proposed in a Phase III work plan. Based on the judgement of the on-site geologist, the borings proposed herein may be drilled slightly d~eper than 75 feet if it appears that the Vertical extent of contamination is only slightly greater than 75 feet. Groundwater should not be encountered in any of these borings and will not be'Considered in this w°rk'~lanl 8 Soil samples will be collected every 5 feet starting at a depth . of § feet except at T.H. No. 1 where sampling will begin at a depth of 40 feet. Selected soil samples will be submitted for analyses. The samples will be analyzed for T.P.H. gasoline and B.T.X.&'E. by SMC Laboratory. The quality assurance and quality control of the laboratory is available from SMC Laboratory on request. ~ 'Chain of custody records documenting sample handling. ~ill be included. ~Soil samples will be collected using a split-spoon sampler driven into the soil utilizing a truck-mounted continuous flight hollow" stem auger rig (Mobile Drill B-§3). The split-spoon sampler contains three two and one-half inches diameter by six inches long brass tubes. The sampler will be driven through the proper sampling interval after the hole is drilled with the hollow stem auger. The sampler will then be removed from .the drilling equipment and the brass tubes removed from the sampler. The ends of one tube from each sample depth will be covered with Teflon seals and polyethylene caps and then sealed with du~t ~ape. The tube will then be labeled and placed in apolyethYlene sample bag and the bag sealed and labeled. Each bagged tube will be retained in a chilled state on blue ice. Selected samples will be delivered to SMC Laboratory for analyses. 9 Another soil' ~ample from each sample depth will be retained for field screening and soil descriptions. Field screening will consist of a headspace reading for hydrocarbon vapors with an Hnu PID meter calibrated to a benzene standard. In addition to the headspace readings, hydrocarbon odors, if present, wilI be noted. The'augers will be steam cleaned between the drilling of each borehole to avoid cross contamination· .The sampling equipment will be scrubbed, washed, and"~horoughl¥ rinsed between each sample collection. The test holes will be backfilled with a cement-sand slurry mix. Contaminated drill cuttings, as identified by field screening, will be placed in DOT drums for future treatment or disposgl.

GEOLOGY AND HYDROGEOLOGY The site lies in a residential and business district in East Bakersfield within two and one-half miles of the Kern River to the north. It is underlain by unconsolidated alluvial sediments deposited by the Kern River through time1. Due to the location's, proximity to the river and its Sierra Nevada Mountain source area, the soils in the area are expected to consist mostly of coarse quartz-rich sands and gravels. Nine and one-half feet of surface silts underlain by sands and gravels were logged in the test hole augered by Duane R. Smith and Associates (Appendix 1). According to maps published by the Kern County Water Agency2 depth to groundwater of the regional unconfined aquifer is approximately 160 feet. A body of shallow perched groundwater · also occurs in the vicinity where clay layers interrupt the downward movement of water. The most recent map for the Summer of 1989 shows the northern lobe of this perched water to be situated south of Bakersfield, although in the past it did extend into the area3. This information and the lack of groundwater occurrence in the D. R. Smith auger hole indicates that no perched water is to be expected. PROPOSED BORINGS Two borings are proposed to complete the characterization of this site (see plot plan, Plate 1). Boring #1 will be located at the gasoline dispenser and it will be angle drilled under the dispenser and the building in which it is located. It will be advanced to a depth beyond 35 feet and at least ten feet deeper than the last detected contamination as indicated in the field by odors and readings recorded by a photoionization meter. Its objective will be to determine the vertical extent of the gasoline plume. Ms. Flora Darling County of Kern Department of Environmental Health Services November 8~ 1990 page Ttn'ee Boring $$2 will also be angle drilled beneath the building, but at a location 12 feet north of Boring #1. It will be drilled 10 feet beygnd the last detected contamination. Its purpose will be to delineate the lateral extent of the plume. Because of the localized .origin of the leak and because of the porous nature-of' the underlying sOils, 'it is anticipated 'that the'lateral Spread of the" contamination will be limited. Drilling the second hole with a 12 foot offset should be sufficient to intersect the outer margins of the plume. Should high levels of hydrocarbons in the secOnd boring indicate the lateral extent of contamination is greater than anticipated, a third boring will be made. pROCEDURES .......... The"borin~s Will be made by RESNA Industries' uSin~ a holl0v~~ s~e~: ~/ii'ger drilling rig. Samples will be obtained every five feet with a California split-spoon sampler. A GRI geologist will describe the samples, screen them with a photoionization detector and seal them in brass sleeves with teflon lined caps. The samples will be labeled and chilled on ice and then taken to SMC Laboratory, 3155 Pegasus Drive, Bakersfield, for analysis under a chain o.f custody document. Selected samples will be analyzed for BTXE and TPH (gasoline). Augers will be steam cleaned between holes to prevent mss-contamination. Contaminated soll brought to the surface by the drilling operations will be place on plastic sheeting and covered for later disposal at a proper facility. Holes in which contamination is found will be abandoned by filling them with cement slurry by the ~emie method. If no contamination is indicated, the borings will be backfilled with clean soil brought to the surface during the drilling operation. After field operations are completed and samples analyzed, a report will be prepared for your office with all results, interpretations and recommendations for remedial action ff required. HEALTH AND SAFETY All GRI employees have received the Health and S~ety training required by OSHA for hazardous waste site operations (29 CFR 1910.120). While conducting the borings, personnel will be equipped with a photoionization detector and LEL-oxygenmeter with Which to monitor the air for organic vapors and combustible gases. Personnel are also issued air-purifying respirators (APR) with organic vapor canisters which can be donned if conditions warrant. One self-contained breathing apparatus (SCBA) is also available on location. Gasoline fuel constituents are the identified hazardous substances at the Sequoia Paint site. The more volatile components, especially benzene, pose the greatest health hazard. The permissible exposure limit for benzene is 10 ppm, which was not exceeded in any of the soil samples. Because of the outdoor location and the intermittent nature of drilling operations, it is not considered likely that personnel will be exposed to elevated levels of hydrocarbon vapors for any length of time. Under these conditions personnel will work under "Class D" protection.. If odors and elevated readings are noted on air monitoring equipment, APRs will be put on and operations suspended till site safety is evaluated. Colorimeter tubes can be used to determine the concenlrations of specific contaminants in the air. A "tailgate" safety meeting will be held at the site prior to commencing operations at which all site hazards and procedures to follow in event of an accident will' be reviewed.

Hollow Stem Auger 1. Soil borings drilled by the hollow stem auger utilize continuous flight hollow stem augers. 2. Augers, samplers and all downhole equipment are steam cleaned prior to ................ - ...... = ..... -:,=- ............... -: .......... - ................ use.. In...the_field steam: cleaning is-done' between~borings-,to.minimize, the. ................ potential for cross-contamination. 3. A G.R.I. geologist observes the work, visually logs the soils, and collects samples at appropriate intervals. 4. The Unified Soils Classification System is utilized to classify soils encountered. Additional geological observations are noted as appropriate." 5. Soil samples destined for laboratory .analysis are collected by a modified California Split Spoon. This sampler uses three, six inch long, by two and one-half inch diameter (o.d.) tubes. Various tubes can be utilized to accommodate the type of analysis necessary: Brass All organics and general analyses (not to be used for copper or zinc analysis) Stainless Steel All organics and metals analyses for Steel copper and zinc (not to be used for chrome or nickel analyses) Plastic All metals analyses (not to be used for organics) 6. The tubes axe cleaned and prepared in the G.R.I. laboratory. Tubes axe scrubbed, inside and outside, with a brush and TSP, rinsed, dryed, and packed in clean containers with seals. Tubes axe delivered to the drilling site in these closed containers to preserve the state of cleanliness. 7. After the sample(s) have been removed from the sampler, the sampler is completely disassembled and scrubbed in TSP and tap water. It is then rinsed in clean tapwater and reassembled with three clean tubes. 8. Dirty tubes axe field washed in TSP solution, rinsed with water, and reused. · 9. The sampler is driven by a 140 pound hammer with a 30 inch free fall. Blow counts are recorded as number of blows per inch of drive. ...... .... ' ............... · ............._10 ....... The sampler~is_driven 18 inches-at each sampling interval. The f'trst (or ....... lowest) tube is generally retained as the sample for analysis. The other two tubes axe retained for back-up or split samples. PAGE 1 GROUNDWATER RESOURCES, INC. SAMPLING PROTOCOL TEST BORING PROCEDURES (continue~) 11. A sand catcher is used in the sampler where loose soils are anticipated. This will prevent the soil from falling out of the sampler. 12. After retrieval, the sample is visually logged and immediately sealed with aluminum foil lined caps, labeled, and chilled. Clean ice chests and chemical ice ("blue ice") are used to keep the samples cold until delivered to the chemical laboratory. Teflon seals axe also available for field samples. 13. Samples are delivered to the laboratory the same day they are taken, if physically possible. If the samples must be held until the next day, they are 14. Sample control is maintained by a Chain of Custody form which accompanies the sample. The form documents the time, date, and .responsible person during each step in the transportation process. MONITORING WELL SAMPLING PROTOCOL II. Groundwater Sampling A. All equipment that is used in a monitoring well for purging, sampling, or depth measurement is decontaminated by steam cleaning or a TSP wash and rinse procedure prior to use and before re-using when more than one sample is collected. B. Purge Volume Determination The following procedure is followed to determine the appropriate purging volume prior to well sampling. 1. The depth-to-water is measured by a clean, electric level indicator. Measurement datum is the top of well protector. 2. Depth to the bottom of the well is measured by a clean tape and plumb bob. If possible, this is compared to thc well construction .log to determine inconsistencies, i.e. damaged casing, sediment in casing, etc. 3. Water volume is calculated by using the total water depth and the inside diameter of the casing. C. Well Purging and 'Sampling " 1. Prior to sampling, a minimum of three to five well volumes are purged from each well to ensure that water sampled is representative of the groundwater within the formation. .................... 2~ . Measurements of.-H, conductivity and temperature are taken at frequent. ,. intervals during the purge. Stabilization of these values indicates that representative formation fluids are being removed from the well. PAGE 2 GROUNDWATER RESOURCES, INC. SAMPLING PROTOCOL MONITORING WELL sAMPLING PROTOCOL (continued) 3. In the event that the well is pumped dry, and alternate procedure will be followed. Once a well is pumped dry, the water that enters the well during ........ · _.._.recovery is, .by. definition, representative formation ,water..The ~wellwill,=~. " ---'-' -:'-' --.~-- -: ......therefore, be pumped dry and allowed to recover to 80%:or-'"mo~ 6f original water level. 4. Purge water is pumped directly into barrels on site until the proper method of disposal is determined. 5.

Samples are delivered by courier, directly to the lab on the same day of sampling, whenever practical. If next day delivery is necessary, the samples are kept refrigerated at 4 degrees C overnight and delivered to the laboratory the following morning. 7. Samples are accompanied by a Chain of Custody form which dOCuments the time, date and responsible person during each step of the transportation process. 8. The G.R.I. coded sample numbering system allows identification of sample and client to G.R.I., while not revealing the client to anyone else. PAGE 3 GROUNDWATER RESOURCES, INC.
