TA2 SITE CHARACTERIZATION STUDY FORMER MOBIL STATION INTRODUCTION A site characterization study has been performed for the former Mobil gasoline station located at 901 Panorama Drive in Bakers- field, California. The site is situated in the northwest quarter of SectiOn 16, T.29S., R.28E., M.D.B.& M. at the southeast corner of Panorama Drive and River Boulevard (see Figures 1 and 2). The site is currently used as.an automotive smog-check shop. The general area is mostly residential. A liquor store is located just east of the site (see Figure 2). A cemetery is located to the west of the site and bluffs of the Kern River are located to the north (see Figure 1). The facility Permit number is 080003. The purpose of this study is to determine the degree and extent of soil contamination resulting from unauthorized releases of hydrocarbons into the subsurface at the site. This investigation included an inspection~of the site, drilling and logging of 4 'test holes, chemical analyses of selected soil samples, research of available materials, review of existing data, and the prepa- ration of this report by Mr. Duane R. Smith, Regist.ered Geologist No. 3584 and Mr. Thomas F..Gutcher, Staff Geologist. ~ . ~ o 6 % ~. ~?

Figure 1 '" The geological investigation reported herein has been conducted in accordance with generally recognized and current state-of-the- art geological p~ocedures. Th9 geological factors that were considered are outlined in this report. Other geological factors were not considered inasmuch as they were not deemed relevant to the intended land use and scope of this investigation. This investigation was conducted to the best of the investigative geologists' abilities in accordance with the foregoing limita- tions. SITE BACKGROUND The site was utilized as a gasoline station from 1960 to 1986 when it was permanently closed as a gasoline station. The station operated under the Union Oil Company name~from 1960 to 1980 and then under the Mobil Oil Company name from 1980 to 1986. Four underground storage tanks were removed from the property in December 1986 by Mundorf Construction.. Two gasoline tanks, a waste oil tank, and a heater oil tank were situated on the property approximately as shown on Figure 2. The gasoline tanks reportedly had a capacity of 6,000 gallons, however, the tank dimensions, as shown on the original site maps, indicate a capacity of about 8,500 gallons. The waste oil and heater oil tanks had a Capacity of 200 gallons each. The product lines ran between the tanks and dispenser islands approximately as shown on 2 Figure 2. No information is available regarding the condition of the tanks upon removal. The locations of the tanks and product lines, as shown on Figure 2, are based'on previous work by another consultant. There are no known reports of discrepancies or reportable varia- tions in inventory monitoring, failed tightness tests, repairs to' tanks or piping, or past leaks. Preliminary Site Assessment Results The analytical results and chain of custody record from the preliminary site assessment are included in Appendix A. Eighteen soil samples were collected by Patrick and Henderson, Inc. and submitted to SMC Laboratory for analyses. Samples associated with the gasoline tanks were analyzed for T.V.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. Samples associated with the heater oil tank were analyzed for oil and grease. The T.O.X. and total lead analyses were performed by B.C. 'L~boratories. The sample locations are shown on Figure 3. Sample T1 West @ 2' was collected at a depth of 2 feet beneath the west end of Tank 1. This sample reportedly contained 1,880 . ppm T.V.H. and high levels of B.T.X.& E.

Sample Ti East @ 2' was collected at a depth of 2 feet beneath the east end of Tank 1. This sample reportedly contained 10 ppm T.V.H. and traces of o-xylene and isopropylbenzen~. Sample TI East @ 5' was collected from the same location at a depth of 5 feet beneath the tank. This sample. reportedly contained 7.9 ppm T.V.H. and traces of o-xylene and isopropylbenzene. Sample T2 West @ 2' was collected at a depth of 2 feet beneath the west end of Tank 2. This sample reportedly contained 67 ppm T.V.H.' and low levels of B.T.X.& E. Sample T2 West @ 6' was collected from the same location at a depth of 6 feet beneath the tank. This sample reportedly contained 233 ppm T.V.H. and moderate levels of B.T.X.& E. Sample T2 East @ 2' was collected at a depth of 2 feet beneath the east end of Tank 2. This sample reportedly contained 5.9 ppm T.V.H. No B.T.X.& E. was detected in this sample, sample T2 East @ 6' was collected from the same location at a depth of 6 feet beneath the tank. This sample reportedly contained 2.0 ppm T.V.H. No B.T.X.& E. was detected in this sample. Sample T3 @ 2' was collected at a depth of 2 feet beneath the bottom of the waste oil tank. 'This sample reportedly contained 135 ppm oil and grease and 2.91 ppm total lead. Sample T3 @ 6' was collected at a depth of 6 feet beneath the waste oil tank. 4 This sample reportedly contained 209 ppm oil and grease and 10.2 ppm total lead. No T.O.X. was detected in either of these samples. Sample T4 @ 2' was collected at a depth of 2 feet beneath the heater oil tank and reportedly contained 135 ppm oil and grease. Sample T4 @ 6' was collected at a depth of 6 feet beneath the heater oil tank and reportedly contained 145 ppm oil and grease. Sample L-1 @ 2' was collected at a depth of 2 feet beneath the product lines at sample location L-1 (see Figure 3). This sample reportedly contained 12 ppm.T.V.H, and traces of.benzene and toluene. Sample L-1 @ 6' was collected from the same location at a depth of 6 feet beneath the product lines. This sample report- edly 'contained 4.5 ppm T.V.H. and traces of toluene. Sample L-2 @ 2' was collected at a depth of 2 feet beneath the product lines at sample location L-2 (see Figure 3). This sample reportedly contained 3,115 ppm T.V.H. and very high levels of B.T.X.& E. Sample L-2 @ 6' was collected from the same location at a depth 'of 6 feet beneath the product lines. This sample reportedly contained 1,126 ppm T.V.H~ and high levels of B.T.X.& E. Sample PI #1 @ 2' was collected at a depth of 2 feet beneath grade level alogg the south edge of'the northern dispenser island (sample location PI-1 on Figure 3). This sample reportedly contained 5.5 ppm T.V.H. and traces of xylenes. Sample PI #2 @ 5 2' was collected at a depth of 2 feet beneath grade level along the south edge of the southern dispenser island (sample location PI-2 on Figure 3). This sample reportedly contained 2.3 ppm T.V.H. and traces of toluene and xylenes, six foot samples at the dispenser islands were not colleCted because of difficult sampling conditions. These results indicate the following: (1) significant gasoline contamination beneath the west end of Tank 1, (2) minor oil and grease contamination beneath the waste oil and heater oil tanks, and (3) significant gasoline contamination beneath the product lines in the vicinity of sample location L-2 (see Figure 3). Previous Work Three test holes were drilled at the site on July 2~ 1987 under the supervision of Patrick and Henderson, Inc. The locations of Test Hole Nos. 1-1, 1-2, and 2-1 are shown on Figure 4. The following discussion on these test holes is based on a report by Patrick and Henderson, Inc. dated February 24, 1988. These test holes apparently were drilled with' a bucket auger drilling.rig. Test Hole No. 1-1, located near the west end of Tank 1 (see Figure 4), was drilled to a total depth of 20 feet. Loose, sandy backfill was encountered from the surface to total depth. Hydrocarbon odors in the soil were noted to a depth of at least 6 TEST HOLE LOCATION 15 feet. Soil samples were collected at depths of 10, 15, and 20 feet. The hole collapsed at the 20 foot depth and was abandoned. Test Hole No. 1-2 was then drilled about 11 feet west-southwest of T.H. No. 1-1 (see Figure 4). This hole was abandoned at 4 feet because of difficult drilling conditions. Test Hole No..2-1 was then drilled in the vicinity of the~product lines east of the southern dispenser (see Figure 4). This hole als° encountered drilling refusal at a depth of 4 feet. Strong hydrocarbon odors were noted. A backhoe was then utilized to extend the total depth to 8 feet. A soil sample was collected at 6 feet and very strong hydrocarbon odors were noted at 8 feet. The hole was abandoned at 8 feet because of collapsing sidewalls. Because hydrocarbon odors were noted in all of the samples collected from these test holes, no samples were submitted for laboratory analysis. A simplified log of T.H. Nos. 1-1 and 2-1 is included in Appendix B, page B-1. Subsequent to the drilling of T.H. Nos. 1-1, '1-2, and 2-1, William H. Park and Associates (now Duane R. Smith and Associ- ates) was retained to continue characterization of the site. Three additional test holes, T.H. Nos. 1, 3, and 3A (see Figure 4), were drilled in an attempt to characterize the contamination and to assess drilling capabilities in the rocky sediments beneath the site. The numbering scheme resulted from a previous work plan. Not all of the test holes proposed in the previous work plan were drilled, however, the original proposed test hole numbers were retained. Several soil samples were submitted to SMC Laboratory for analyses. Test Hole No. 3A was drilled on May 2, 1989 just west of Tank 1 (see Figure 4). It was drilled to a depth of 22.5 feet with a hollow-stem continuous flight auger rig. Drilling refusal occurred at 22.5 feet where the hole was abandoned. Soil samples were collected at depths of 10, 15, and 20 feet for field screen- ing, but were'not submitted for laboratory analysis. Field screening indicated the presence of hydrocarbons from a depth of about 10 feet to total depth (see Appendix B, page B-7). Test Hole No. 3 was drilled on July 13, 1989 about 5 feet west of T.H. No. 3A (see Figure 4). It was drilled to a depth of 32 feet with an air'rotary rig using mud mist. This'boring was drilled using air circulation only until the formation began to collapse into the boring. Light bentonite drilling mud was then sprayed on.the boring sidewall in an attempt to hold back the formation. Soil samples were collected at depths of 15, 20, and 30 feet and submitted for chemical analyses (see Appendix B, page B-8). No hydrocarbons were detected in the 15 or 20 foot samples (see Appendix C, pag~ C-5). Traces of hydrocarbons were detected in the 30 foot sample (see Appendix C, page C-6). The boring was abandoned at 32 feet when the top of the boring began to col- lapse. Test Hole No. 1 was drilled on July 13 and 14, 1989 between Tank 1 and the product lines (see Figure 4). It was also drilled with an air rotary rig using mud mist when air circUlation was no longer adequate. Total depth of T.H. No. 1 was 75 feet. Soil samples were collected where possible. The rocky formation cannot be indiscriminately sampled without destroying the sa~- pling e~uipment. 'Suitable sample depths, as identified by the driller, resulted in the collection of samples at depths of 30, 33, 41, 50, and 59 feet. Only the 33, 41, and 50 foot samples were deemed adequate for laboratory analysis (see Appendix B, pages B-2 and B-3). The results of these three samples indicated significant gasoline contamination. Test Hole No. 1 was aban- doned at a depth of 75 feet when the boring began to collapse. Field screening indicated the presence of hydrocarbons to total depth (see Appendix B, pages B-2 and B~3), but the odors noted below~50'feet may have emanated from the boring sidewalls at lesser depths. Test Hole Nos.. 1, 3, and 3A were b~ckfilled ~ith a cement-sand slurry from total depth to the surface. Contaminated drill cuttings and drilling mud, as identified by field screening, were placed in DOT drums and legally disposed. 9 SITE GEOLOGY According to the Geologic Map of California, Bakersfield Sheet, the sediments underlying the site consist of Pliocene-Pleistocene nonmarine sedimentary deposits of the Kern River Formation. These deposits consist of poorly bedded to massive, unconsolidat- ed to~loosely consolidated, very poorly sorted subrounded boul- ders and cobbles in a sandy gravel matrix. The sediments encountered in several on-site test holes consist of sandy gravel with abundant cobbles. The deepest test hole was drilled to a depth of 90 feet. The sediments were fairly uniform to this depth. 'Test hole logs are included in Appendix B. Exposures of the Kern River Formation in the bluffs of the Kern River just north of the site indicate that this formation is more than 200 feet thick beneath the property. 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-Cuyama association. In general, these soils consist of well drained moderately fine textured sobls deVeloped from mixed rock sources which were deposited on old alluvial. fans. Based on the 1988 Report on Water Conditions, Improvement Dis- trict No. 4, published by the Kern County Water Agency, the depth 10 to primary groundwater beneath the site is approximately 260 feet. No perched groundwater is known to exist beneath the site. No groundwater was encountered in the test holes drilled at the site, the deepest of which reached a depth of 90 feet. Based on historic water depth data, collected for the period from May 1973 to the Spring of 1990, the depth to primary groundwater beneath the site has fluctuated between about 200 feet and 360 feet beneath the surface (see Table 1). The average depth to primar~y groundwater beneath the site between May 1973 and the Spring of 1990 was about 285 feet. ADDITIONAL SOIL SAMPLING In accordance with a verbal agreement with the Department~ of Environmental Health Services, County of Kern, one additional deep boring was drilled on November 19, 1990. This boring was drilled in an attempt to determine the vertical extent of gaso- line contamination at the site. This test hole, designated T.H. No. 2, was drilled about 3 feet west of T.H. No. 1 (see Figure 4) to a depth of 90 feet. Soil samples were collected at 5 foot intervals starting at 55 feet below the surface. Since T.H. No. 2 was located adjacent to T.H. No. 1 where samples were collected and analyzed at.depths of 33,°41, and 50 feet, no samples were collected from the first 50 feet of T.H. No. '2. Sample recovery was poor at a few sample depths due to the presence of gravel. 11 DEPTH TO GROUNDWATER MAY 1973 THROUGH SPRING 1990 FORMER PANORAMA MOBIL STATION DATE RECORDED DEPTH TO GROUNDWATER SOURCE May 1973 335' 1973' September 1973 355' 1973' July 1974 360' 1974' Fall 1977 320' 1977b Spring 1981 200' 1980b Spring 1982 310' 1981b Spring 1983 270' 1982b October 1983 350' 1983' Spring 1984 275' 1983~ Spring 1985 360' 1984~ Spring 1986 250+' 1985~ Spring 1987 250+' 1986b September 1987 330' 1987' Spring 1988 250' 1987b September 1988 260' 1988" Spring 1989 200' 1988~ Spring 1990 200+' 1989~ Sources: · - Kern County Water Agency, Improvement District No. 4, 'Report on Water Conditions, year of report listed. ~ - Kern County Water.

No. 2 Were submitted for chemical analyses ~ The samples were analyzed for T.P.H. gasoline 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 C. The quality assurance and quality control of the laboratory are available from SMC Labora- tory on request. The analytical results of the five samples from T.H. No. 2 submitted for analyses are included in Appendix C, pages C-3 and C-4. Test.Hole No. 2 was drilled using a Drill Systems AP-1000 dual- wall percussion hammer drilling rig using air as the only circu- lating medium. Since field screening indicated no significant contamination below 65 feet, the boring was terminated at a depth of 90 feet instead of the proposed 150 feet. Soil samples were collected using a split-spoon sampler driven into the soil through the dual-wall drill casing. The split- .spoon sampler contained f6ur two and one-half inches diameter by six inches long brass tubes. The sampler was driven through the proper sample interval after the hole was drilled to the proper sample depth. The sampler was then removed from the drilling equipment and the brass tubes removed from the sampler. The ends of one tube from each sample depth were covered with Teflon seals and polyethylene caps and then sealed with duct 12 tape. sample bag and the bag labeled and sealed. retained in a chilled state on blue ice. delivered to SMC Laboratory for analyses. The tube was then labeled and placed in a polyethylene Each bagged tube was Selected samples were Another soil sample from each sample depth was retained for field screening and soil descriptions. Field screening consisted'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, were noted. The results of the field screening along with.the soil descriptions are shown on the test hole logs (see Appendix B). The drill casing was steam cleaned after drilling the borehole. The sampling equipment was scrubbed, washed, and thoroughly rinsed between each sample collection to minimize the potential for cross-contamination.. The test hole was backfilled with cement bentonite grout placed as the drill string was removed from the borehole. Contaminated drill cuttings, as identified by field screening, were placed in DOT drums for future treatment or disposal. ° 13 RESULTS OF SITE CHARACTERIZATION Appendix C shows the analytical results of the eleven samples collected from T.H. Nos. 1, 2, and 3 which were submitted for analyses along with the corresponding chain of'custody records. Appendix B shows the boring logs of T.H. Nos. 1-1, 2-1, 1, 2, 3, and 3A. No samples from T.H. Nos. 1-1, 2-1 or 3A were analyzed. The 33, 41 and 50'fo°t samples from T.H. No. 1 were analyzed. The 65, 70, 75, 80 and 90 'foot samples.from T.H. No. 2 were ana- lyzed. The 15, 20 and 30 foot samples from T.H. No. 3 were ana- lyzed. Sampling difficulties prevented collection of samples from several depths in the test holes (see Appendix B). The 33 foot sample from T.H. No. 1 reportedly contained 1,600 ppm T~P.H. gasoline and high levels of B.T.X.& E. The 41 foot sample reportedly contained 1,700 ppm T.P.H. gasoline and high levels of B.T.X.& E. The 50 foot sample reportedly contained 560 ppm T.P.H. gasoline and moderate levels of B.T.X..& E. The analytical results of the selected samples from T.H. No. 1 are included in Appendix C, pages C-1 and C-2. The 65 foot sampl9 from T.H. No. 2 reportedly contained 67 ppm T.P.H. gasoline and low levels of B.T.X.& E. The 70 foOt sample from T.H. No. 2.reportedly contained 13 ppm T.P.H. gasoline and traces of B.T.X.& E. No T.P.H. 'gasoline or B.T.X.& E. were detected in the 75, 80, or 90 foot samples from T.H. No. 2. The 14 analytical results of the selectedsamples from T.H. No. 2 are included in Appendix C, pages C-3 and C-4. No T.P.H. gasoline or B.T.X.& E. were detected in the 15 or 20 foot samples from T.H. No. 3. The 30 foot sample' from T.H. No. 3 reportedly contained 2.0 ppm T.P.H. gasoline and traces of xylenes and isopropylbenzene. The analytical results of the selected samples from T.H. No. 3 are included in Appendix C, pages C-5 and C-6. CONCLUSIONS Figure 5 shows, the locations of cross sections A-At and B-B". Figure 5 also shows the approximate areal extent of the contami- nant plume at a depth of 40 feet. Cross section A-A' is shown on Figure 6 and depicts a north-south vertical profile of the contaminant plume. Cross section B-B' is shown on Figure 7 and depicts a northwest-southeast vertical profile of the contaminant plume. On both cross sections, T.H. Nos. i and 2, being only 3 feet apart, are shown as one test hole located halfway between the two. Several test holes.and sample locations which are near the cross sections were projected into the cross sections as indicated by the arrows on Figure 5. Subsurface migration of contaminants appears to have been con- trolled primarily by the influence of gravity.

Capillary action in the soil has caused some horizontal migration, but vertical migration was dominant. Since there were multiple sources of contamination, the lateral extent of the contaminant plume is relatively large. 'The maximum vertical extent of the contaminant plume appears to occur aboUt 8 feet southeast of T.H. Nos 1 and 2 at a depth of about'73 feet (see Figures 6 and 7). Trace'levels of contamina- tion were found at some areas outside of the plume depicted on Figure 5, 6, and 7, but the significant contamination appears to be confined to the areas shown. The maximum areal extent of the contaminant plume is estimated to be represented by an irregular- ly shaped, northwest-southeast Oriented ellipse about 26 x 50 feet across (see Figure 5). The data from T.H. No. 2 provides a good def'inition of the maximum vertical extent of contamination. The lateral extent is loosely defined by data from previous borings and the preliminary site assessment as well as by applying reasonable interpretation of fluid migration through highly permeable soil. The plume, as shown on Figures 5, 6, and 7, has been drawn conservatively and may well be substantially smaller. It is not likely, however, tha~ it is substantially larger. 16 It is estimated that the contaminant plume consists of roughly 2,500 cubic yards of soil. .This value was determined by calcu- lating the volumes of horizontally-oriented right-rectangular prisms of various dimensions which approximate the shape of the plume. RECOMMENDATIONS Three possible remedial alternatives for'this site.are excavation and disposal, 'vapor extraction, and a no action alternative. Excavation of the contaminated soil would be very costly. Based on a cost of $300.00 per cubic yard to excavate and dispose Of the contaminated soil, it would cost about $750,000 to complete remediation. This figure is considered conservative due to the depth of the excavation and the need shoring and ramping. It is likely that the actual amount of soil to be excavated would greatly exceed the estimated 2,500 cubic yards of contaminated soil. Also, excavation to such a great depth in a developed area such as this may not be feasible. During the excavation process, B.T.X.& E. constituents would be released to the atmosphere. Excavation personnel, as Well as civilians in the vicinity, would be exposed to these constitu- ents. This remediation alternative could take several months to 17 complete, including the planning stages, and the cost is exces- sive. The second remedial alternative, vapor extraction, would involve drilling several dry wells through the plume and using vacuum pumps to remove the hydrocarbon vapors. This method is fairly effective at reducing contamination levels from gasoline.~ Once the extracted vapor has been reduced to acceptable levels of contamination, a test hole with soil samples would be needed to verify acceptable remediation. Considering the depth of contami- nation and the difficult drilling conditions, the cost to com- plete a'vapor extraction project at this location could exceed $200,000. The system could conceivably operate for many months before acceptable contaminant levels were obtained. The third plan is a no action alternative. This plan seems reasonable based on several factors. First, the source of the' contamination has been removed and no new underground tanks are planned for this property. Second, the depth to the primary groundwater table below ~he property was 200+ feet below the surface in the spring of 1990. The depth to groundwater beneath the site has not been less than about 200 feet over the past 16 years (see Table 1). Therefore, the contaminant plume is in excess of 100 feet above the highest rec'orded groundwater, level. Also, no shallow perched groundwater is known to exist in the vicinity. Third, the property .is located in a developed area 18 covered with asphalt, concrete, and buildings which would mini- mize the infiltration of water. The area around the site is within the Bakersfield'city limits and is serviced by the city sewer system. Therefore, no septic systems or leach lines should affect~the plume. Fourth, no water wells are located in the vicinity. And fifth,~the plume is not present beneath any structures for human occupancy. The plume, which is effectively isolated from the surface, should now stabilize. The area above the contaminant plume is compacted and covered with asphalt and concrete. Any cracks which may exist or develop could be sealed to prevent vapors from venting to the surface and infiltration of surface water which might enhance migration of the plume. Since the base of the plume is more than 100 feet above the highest recorded groundwater depth, the contamination should pose no threat to groundwater. The plume will be isolated from the surface and should pose no short term or long term threat to the environment or biological receptors. We recommend that the no action alternative be undertaken based on the foregoing evaluations. However, it must be understood that as long as the contaminated soil remains below the site, the property Owners are subject to accepting any future liability, however remote the chances of the contamination affecting any biological receptors. 19 Submitted by: Duane R.

Soil contamination, found at the time of removal, did require a full site assessment which has also been Completed. The regulatory agency overseeing the. Underground Storage Tank Program at the time was Kern County Environmental Health. Their letter of April 30, 1991, to Mr. Ralph Smith, trustee for this property, states that the site assessment was completed satisfactorily and that no further action was required at that time. That same letter also states that they are not relieved of any responsibility to clean up existing, additional or previously unidentified conditions at this site and that changes in the land use may require further site characterization and mitigation. The'site is not clean! Contamination appears to extend over a wide and irregular shaped surface area (approximately 50' x 26'), and to a depth of 73 feet. However the depth to groundwater in that area is over 200 feet and therefore the "no action alternative" was accepted as satisfactory. The existence of this contamination must be considered for any land use changes and must be disclosed if and when the property is offered for sale. Effective July 1, 1991 the City has assumed responsibility for the Underground Storage Tank Program within the city limits. The property owner is therefore required to report any changes in the report content, future contamination findings, or site usage to this office. The proposed site usage change to a tire repair shop would not require any additional site characterization or mitigation at this time. Sincerely, Ralph E. Huey Hazardous Materials Coordinator cc: Ralph Smith, Trustee RALPH SMITH REALTY/PANORAMA MOBILE SITE CHARACTERIZATION WORKPLAN PATRICK & HENDERSON, INC. 1999 Edison Highway, Suite 32 Bakersfield, California 93305 INTRODUCTION The purpose of this report is to identify and specify methods to be utilized in determining the extent of the soil contamination previously identified in January, 1987. Refer to Patrick & Henderson, Inc. Report dated January 9, 1987, for test locations and laboratory re- sults. II. HISTORY The site was utilized as a gasoline station from 1960 to 1986 (when permanently closed). The station operated under the Union Oil Company name from 1960 to 1980 and under the Mobile name from 1980 to 1986. A permit was issued in December, 1986 by the Kern County Health Department for abandonment of four underground tanks consisting of two 6,000 gallon gasoline tanks, a 200 gallon waste oil tank, and a 200 gallon fuel oil tank. The tanks were installed around 1960. The tanks were removed in December, 1986 as detailed in Patrick & Henderson, Inc.'s January 9 report. The Kern County Health Department reviewed the laboratory results and determined that the vertical and horizontal extent of the contamination had not been adequately de- termined. .The Kern County Health Department directed us III. to further define the vertical and horizontal extent of the plume in accordance with Kern County Ordinance Chapter 5, Section 39!2.5.03. INVENTORY RECORDS To our knowledge, no inventory records are available. IV. Ve SUBSURFACE HYDROLOGY T~e soils underlying the site are composed of poorly sorted gravels, cobbles and sands with occasional boulders and possibly some clay lenses. Initial sampling indicates frequent cobbles and.boulders making drilling difficult. Groundwater lies approximately 300-350 feet beneath ground surface according to Kern County Water Agency, 1985 Water Supply Report, dated May, 1986, Plate 5. The groundwater table slopes southerly at a rate of about 50 feet per mile. Percolatio,n of fluids in the soils prevalent at the site would be rapid and nearly vertical, especially the gasoline with its low viscosity. Intermittent clayey lenses may have resulted in a greater horizontal mitiga- tion than anticipated. SURFACE HYDROLOGY The adjacent properties are occupied by streets or com- mercial enterprises. The ground surface is paved for at least 75' from the tank location. Site drainage is generally west to River Boulevard via swale on the south boundary of the property. It is unlikely, in our opinion, tko- ~..:~.~ac~{ runoff has entered tile soil and caused mig'ratic~ of any contaminants. VI. SOIL SAMPLING The cobbley soil conditions call for using a 16-24 inch auger for drilling. This should allow penetration of cobbles and small boulders. Field screening of the samples will be do~e with a HNU hydrocarbon sniffer. Bucket loads will be screened' ,.' and those with positive readings will be sampled. Samples will be placed in clean'mason jars and approp- riately labeled. Samples will immediately be placed in an ice chest and kept near 50°F until analysis. Afor 5 feet will be retained. minimum of one sample every Two to six holes are proposed (See Plate I). A'chain of Custody Document will follow the samples. The results of the previous testing show the contaminants concentrated in two areas: Area 1: The west end of tanks 1 and 2 6,000 gal. gasoline) show levels of >1,000 TVH at 6 feet below the tank bottom. Since gasoline is a low viscosity liquid and ,the soil is believed to be very permeable, the primary concern is the vertical extent of contamination. Should sample screening indicate clean material at some depth, drilling in that hole will be term- inated. A sample at this depth will be taken to verify the absence of contaminants. After backfilling the hole with native material, we will move to a location/'20' east and again determine the vertical boundary. If the boundary' ,' southwest from Hole is reached, we will move(~' No. 1 and determine verti'~al extent at this point (See Plate I ) . zO t This'method will give an estimate of the slope of the plume (assuming a point source) will allow us to' describe its approximate shape. If we are unable to reach the vertical boundary of the plume .in the first hole, we will not drill the other two perimeter holes. The information gained would be of little value should we have hydrocarbons below 50 feet in the first hole. VII. B o . Area 2: The sample location L-2 showed TVH leQels of >3,000 ppm at 2' and >1,000 ppm at 6 feet. Strong hydro- carbon odors were reported. A log of the soil types encountered will be developed as the drilling progresses. Soil moisture content, color, grain size distribution, etc. will be record- ed in a field log book. The location of the holes will be measured from property corners or permanent reference points. CHANGED SITE CONDITIONS " The drilling operation may reveal-unexpected site soil and geologic conditions. Should unexpected conditions arise, the location, number and depth of the holes may need to be altered. Any alterations to the work plan will be cleared with the Health Department prior to implementation. VIII. SAMPLE QA/QC Samples will be placed in clean mason jars and kept near 50°F until transport to SMC labs the same day or following morning. Samples will be properly labeled and sealed according to SW-846 Section 1.3. Method of analysis will be EPA 5020/8020 Section 5 and 8 of SW-846. IX. WORKER SAFETY The use of hard hats, boots and qloves will be required for site personnel. Sample retrieval will require working in close proximity of the drill rig and hole. The sample can be taken off the auger with the auger partially in the hole. The technician will signal 'the operator when a sample is needed. After the auger is raised and stationary, the technician will scoop a portion of the takings from ~he bottom portion of the auger and move to a safe working area for checking with the sniffer. Hearing protection may be necessary depending on.the rig being used. FINAL REPORT~ A final report will be submitted to the Health Depart- ment presenting the results and conclusions derived from the field acti'vities. Site mitigation measures will be presented and dis- cussed. The discussion will include: B. C. D. E. F. Cost-benefit analysis. Short term effects to soil and groundwater. Long term effects to soil and groundwater. Modes of contaminant transport. Effect on biological receptors. Schedule for implementation. A minimum of two site mitigation measures will be pre- sented. A non-action plan will also be discussed'. The final report will be submitted to the Health Depart- ment within 30 days to the Health Department within 30 days· after the sampling is completed.

(P & H, Inc.) was retained as the environmental assessment contractor to collect soil samples associated with the abandonment of three underground fuel storage tanks and an under- ground waste oil tank at the now defunct Panorama Drive Mobile gas station in Bakersfield, California. The Kern County Health Department issued Permit Number A327-08 on December 12, 1986 allowing for the subject tank abandonments. Mundorf Construction executed the tank removals on December 19, 1986 following the procedures set forth by the Kern County Health and Fire Departments. A represeotative of P & H, Inc. was present at the site to record field observations'and to collect the required soil samples for laboratory analysis. Site sampling activities were conducted by P & H, Inc[ on December 23, 1986 under the supervision of the Kern County Health Department ABANDOnmENT PROCEDURES Mundorf Construction began excavation of site soils on December 19, t'986 exposing the twin 6,000 gallon gasoline storage tanks and the twin 200 gallon waste oil and heating oil tanks. Dry ice was introduced'to the tanks the same day following the disconnection of product lines. A Kern County Fire Department representative was present.and.gave..~appro~aI to remove the tanks. Product lines between the gasoline tanks and pump islands were exposed for the purpose of identifying their precise locations and to allow selection of test holes for sub§equent sampling. Concrete adjacent to the pump islands was removed to allow for soil sampling. Subsequent to the P & H sampling ~activities, the tank pit excavations were roped off to prevent any potential accident. The accompanying site plan delineates tank, piping, and pump island locations. FIELD OBSERVATIONS/SAMPLING PROCEDURES Two sets of soil samples were obtained at 2' and 6' beneath each of the 6,000 gallon gasoline tanks. One set of samples at 2' and 6' beneath the Waste and Heating Oil tanks were'collected. The product line was sampled at two locations at depths of 2' and 6". Due to rocky soil conditions only one sample could be obtained at each of the pump island test hole locations, the depth being 2' below piping. Test hole locations are shown on the Site Plan. Soil samples were obtained via use of a backhoe and the P & H sampler where 'feasible, and with glass jars where not. Effort was made to Use the P & H sampler because it produces an undisturbed soil core. However, only a thin Veneer of soil exists at this site. According to Michael R. Rector, Inc. beneath this soil mantle exists a series of poorly sorted beds of sands and gravels with occasional boulders of the non-marine Kern River Formation. These beds can be encountered at several exposures along the river side of the "bluffs" between Manor Street and the abandoned (County) Panorama Solid Waste'Disposal Site. ' Moderateiy stained soils were observed at the west end'of tank #2 upon being exposed. The staining and moderate odors persisted at this locations down to the 6 feet below tank bottom level. Slight odOrs were noticeable at the west end of tank #1, though no soils stains were observed. Soil staining to a depth of four or five feet below finish grade was pronounced in the pit excavated to abandon tank #3; however this cannot be attributed to any leakage from the tank. Soils beneath the tank appeared to be clean and were odorless. No soil staining or hydrocarbon odor was evident beneath tank #4. Soil observations at the pump island test locations could not be observed because of the concrete pad present there. Due to rocky soil conditions only one sample could be obtained, at 2 feet below finish pad, at each of these test holes. Daylight was diminishing by the time the soil sampling was conducted at the two product line test hole locations. Samples were obtained at 2' and 6' below the piping at both places. No 9dors were detected at the L-1 test hole. Very strong odors were detected in the L-2 test hole, with maxi- mum st'rength occurring at about 4 feet below grade. ANALYSIS All samples were stored overnight before transport ~o SMC Laboratory for chemical analysis the fo!lo~ing day. Gas tank, lime an~ pump island samples were analyzed for the following constituents: benzene, Toluene, ethylbenzene, xylenes, and total volatile hydrocarbons. Samples beneath the Waste Oil and Heating Oil tanks were tested for oil and grease, total organic halides (TOX) and total lead. BC Laboratory performed the TOX and total lead analyses. Sample analysis sheets indicate the presence of a minor amount of contamination in the pump island samples and the first line test hole samples. At the C-2 test hoie a significant amount of~¢ontamination was identified. The contaminant ievels reported here~decreased from the 2' test to the 6' test by a factor of three to ten for most o the constituents analyzed. Moderate contaminant levels of oil and grease were reported for both the Waste Oil and Heating Oil tank soil samples. In each case there was a slight increase from the 2' sample to the 6' sample. No organic halides were detected in the s~mples beneath th~ Waste Oil Tank (T-31; however B.C. Laboratory detected minor amounts of lead in both samples. The east ends of the 6,000 gallon gasoline tanks produced relatively clean samples. The west end of Tank #1 (Premium Unleaded) produced samples with minor'to moderate contaminant levels. Slight increases in all constituents were reported from the 2' to the 6' samples. The area of primary concern appears to be at the west end of Tank #2 (Unleaded) where significant amounts of contamination were detected in both the 2' and 6' samples. Michael R. Rector reports that within all geologic units of the Kern River Formation deep percolation can be quite rapid until a clay bed or lense is encountered by the percolating fluids. On that basis, it is most probable that near vertical migration of fluids should occur, if they have been introduced into the Kern River Formation. The ~roundwater table lies approximately 350 feet below the Site, according to the 1985 Report o~ Water Conditions, Improvement District No. ~ by Kern County Water Agency,'February 2, 1986. T~e water table surface ~slopes in a southwesterly direction at a rate of about 50 feet per mile, according to that p~bli~ation.

As you are aware, the test holes were going to be drilled with Layne Environmental's hammer dril-ling rig. The cost for this rig is high, so we tried a hollow stem flight auger drilling rig. We were unable to drill through the rock with this~rig. I talked with Rick Redfeairn of Den's Drilling CopmPany and he feels that the test holes can be drilled and soil samples collected using an air drilling rig. If this method works, the cost could be less than half the Layne cost. I plan on trying Den's.drilling rig on July 5, 1989. We should know if it is going to work within a couple of hours.

Station Dear Ms. Gough: ' Mr. Jeff Mills of Patrick and Henderson, Inc. has retained our firm to complete the site characterization for the Panorama Drive Mobil station. Mr Mills has already~Prepared · a site characterization work plan and it has been reviewed by your office. In a letter dated March 3, 1989 you stated several concerns dealing with the plan. The depth to primary groundwater below the property was about 350 feet in December 1987. I do not feel that the test holes will exceed 100. feet. I am planning, at this time, that they will be about 50 feet each. The results of the chemical analyses for the preliminary.assessment were not very high. At 18 feet the highest concentration for T.V.H. was 1,370 ppm. Based on the above discussion, I am not planning on placing cuttings in drums and the test holes will be backfilled.with the cuttings. I also feel that the contamination is minor and.fairly shallow and it may be able to be left in Place. Each drill hole will be geologically logged by a geologist. Each soil sample will be collected at approximately five foot intervals and field screened. Selected samples will be analyzed at $.M.C. Laboratory to verify the field screening. ~' Ms. Dolores Gough c/o Kern County-Environmental Health Services Department April LO, 1989 Page 2 Drilling the test holes has presented somewhat of a Problem. Two methods are available. These are a hollow stem flight auger drill rig and an air percussion drill rig. I have talked with Lloyd Melton about the auger rig. He informs me that they have devised' a way to drill through rock and gravel. They will auger as far as possible and then go down the auger with an air hammer'and continue to drill. The air percussion drill rig would pound casing into the ground. This rig would have no trouble penetrating the rock and gravel. One drawback is that it is very noisy. Collecting soil samples could be difficult with either rig. I would use a drive sampler with.either rig. Samples would be either the typical split spoon with brass rings or a soild pipe sampler that could be driven with more force into the rocks. Depending'on the type of material encountered, soil samples may not be able to be collected at exactly five foot intervals. I plan on collecting the soil samples' at five foot intervals or whenever the drill rig encounters softer sediments. At this time I plan on trying to' drill the test holes with Lloyd Melton's drilling rig. This will be somewhat experimental but Mr. Melton has informed me that he has ~sed this method in rock and gravel in San Diego. If this method works it will be much more cost effective. If we are not able to complete a test hole in this manner, Layne Western will be contacted and an air percussion drill rig will be scheduled to perform the work. I do not want to collect my soil samples from the cuttings unless it is absolutely necessary. WILLIAM H. PARK Ms. Dolores Gough c/o Kern County-Environmental Health Services Department April 10, 1989 Page 3 Several slight changes in Mr. Mills' characterization proposal are planned. Test Hole 91 will be moved about four feet to the west. Test Hole 92 will be moved about ten feet to the southwest since the migration has probably migrated predominantly vertical in these type of sediments. Test Hole 93 will be moved to the west end of Tank 91 Where the highest contamination was found. I will also add a Test Hole 94 if needed. This might be located about fifteen'feet west of Test Hole 93. Attachment A shows the locations of my proposed test holes. Attachment B is a copy of Mr. Mills' site characterization work plan.

CA 93301 Attention: Ms. Janis Lehman Re: Panorama Mobil Site Characterization Nork Plan Ladies & Gentlemen: We are submitting herein 'an updated site characterization workplan. The main differences from our previous workplan are the sampling methodology and drilling technique. Please refer to our June 1987 workplan for site history, surface hydrology and subsurface.hydrology. As you know, the site conditions require the use of an air percussion drill rig .to penetrate the Kern River formation. .There are two methods available for sampling the soil. Ihe first and preferred method is to use the 'split spoon sampler ~nd retrieve samples at five foot intervals. This will be difficult as most soils in the formation are non-cohesive and will not stay in ' the sampler. Should we be in rock the split spoon sampler will be ineffective. The second method is to be used when.split spopn sampling is not possible. This method entails simply catchin~ the drilling tailings at the exit point. The reliability of the second method is in question. We expect the circulating air .to be saturated with' volatile hydrocarbons. Therefore, we would expect to see small concentrations of volatiles in the grab samples from the tailings. Should we reach clean material we hope to get a good split spoon sample to substantiate the finding.' Our proposed drilling program is to consist of three holes to 50' minimum. Depending upon our findings, the program will be expanded until the plume or plumes are adequately defined. Samples will- be analyzed for TPH and BTX + E by SMC labs. samples will be taken in duplicate and immediately placed in clean mason jars and stored below 50°F. All hand tools will be rinsed with a sodium phosphate detergent prior to reuse.

Please 'refer to our June 1987 .... ~-6~kplan for site history, surface hydrology and subsurfa6e hydrology. As you know, the site conditions require the use of an air percussion drill rig .to penetrate the Kern .River formation. There are two methods available for sampling the soil. The first and preferred method is to use. the .split spoon sampler and retrieve, samples at five foot intervals. This will be difficult as most soils in the formation are non-cohesive and will not stay in the sampler. Should we be in rock the split spoon sampler will be ineffective. The second method is to be used when split spoon sampling is not possible. This method entails simply catching the drilling tailings at the exit point. The reliability of the second method is in question. We expect the circulating air to be saturated with volatile hydrocarbons. Therefore, we would expect to see small concentrations of volatiles in the grab samples from the tailings. Should we reach clean material we hope to get a good split spoon sample to substantiate the finding. 6ur proposed drilling program is to consist of three holes to 50' minimum. Depending upon our findings, the program will be exp~an~d_e~_~_~.~__.~.he_~!ume or ~!~umes are adequately defined. Samples will be analyzed for TPH and BTX + E by SMC labs. samples will be taken in duplicate and immediately placed in clean mason jars and stored below 50°F. All hand tools will be rinsed with a sodium phosphate detergent prior to'reuse.

As discussed In our meeting of May 11, 1988, there, are several areas which are of concern to this department regarding this project that must be addressed further. They are as follows: 1. The full. extent of contamination must be defined. There ~----a~re methodologies available to do this, several of which ~..1~5' were discussed with you during our meeting. 'contamination are decreasing with depth, and therefore the leak was small, Is only reflected In the TVH analysis · results. The BTX and ~., oil and grease, and lead analyses results show an increased concentration w. tth depth. This therefore does not correlate with the assumption in the report that the leak was necessarily small.. 3. In a risk assessment discussion the possible routes of migration, and the long and short term threats to biological receptors due to the contaminants present must also be addressed. I -have enclosed a copy of this department's outline for site characterization studles and mitigation proposals.

Lehman: The investigation to ~etermine the extent of the contamination plume cannot be completed due to difficult site conditions. Large cobbles and boulders were encountered in the test holes making drilling and sampling impossible. At test Location 1~1, loose sandy backfill was encountered to a depth of 20 feet. Hydrocarbon odors were observed in the soil to a depth of at least 15 feet. Prior to obtaining a sample at 20 feet, the hole caved to a depth of about 8 feet. An attempt was made to drill a hole adjacent to Location 1-1 outside of the tank excavation area at Location 1-2. Very little progress was'made in advancing test hole Location 1-2 due to large cobbles and boulders. Both locations were then backfilled and abandoned. We then moved to Location 2-1 where presumably, a line had been leaking. At a .depth of 4 feet the drilling operation was curtailed because of refusal. Again, the large Cobbles would not enter the bucket to allow the bucket to advance. Strong hydrocarbon odors were observed coming from the hole. The backhoe was then usgd to excavate down to a maximum depth of 8 feet. No further depth could be reached due to unstable cobbles in the sidewalls of the excavation continuing to Oave. Mark Pishinski was present during a portion'of 'the excavation work and was advised that it would be practically impossible to reach the proposed depth with the type of subsurface material present. We then decided to curtail the investigation because of its limited chance of providing useful information. Analysis of the samples was not performed because all soil encountered had hydrocarbon odors present. American Society of Civil Engineers · Caliiornia Council of Civil Engineers and Land Surveyors · The Better Business Bureau '~{ern Co. Health Dept. Page 2 It is this firm's opinion that, in light of the site conditions, a discussion of possible mitigation measures is appropriate. A.risk Assessment based on the data we currently have is the basis of our discussion and proposal. The primary reference used in this report is the "Leaking Underground Fuel Tank Field Manual" prepared by the State of California,'Leaking Underground Fuel Tank Task FOrce. The discussion will fgllow the Flow .Chart (Figure 11-3) for site investigations of'--si"tes with known or suspected soil contamination. See Appendix'"A". February 24, 1988 METHODOLOGY: The first step is to collect samples and determine if levels of contamination exceed allowable limits. Based on the initial inve.s%-i-~a-t~i~n, there are two areas that have contaminated soils above allowable limits. Next a determination of whether ~he_soi'l-~'contamination is minor must be made. Since the extent is not known, we must presume that it is not minor and proceed on to the general risk appraisal based on known risk factors. The primary risk factor in this instance is the distance to groundwater and the potential migration of contaminants into the aquifer. Seoondary risk factors are other modes of human contact with the contamination such as through excavation of the soil. Based on general risk appraisal, we assess the cost-benefit and overall economic feasibility of a cleanup effort. Using these criteria, we can then propose measures that will ensure protection of the groundwater and the environment, while not imposing an unnecessary economic burden. ' ' DISCUSSION: The two areas of contamination soil are the west end of Tank No. 1 and at L2 adjacent tO th:e~-'-southerly pump island. A TVH level of 1880 ppm @ 2 feet and ~370 @ 6 feet' was found at the west end of Tank No. 1. A TVH of 3~D55-.ppm'@ 2 feet and 1126 @ 6 feet was found at L2. The level of contamination as a function of depth appears to decrease with depth. This indicates one of two possibilities, or a combination of the two. Assuming a typical contamination plume shape"e~i-tke4~'"~'~e spill was small and saturation of the soil occurred at'the upper level and diminished with depth, or a variation in the void ratio of the soil caused more or less contaminant to be retained depending on the soil type. .From my observations at the site (Location 2 only), the soil was consistent in gradation by~ visual methods. My conclusion is that in all probability the spill Kern Co.. Health De Page 3 February 24, 1988 at L2 was small and contaminated soil does not extend ¥~r~y deep. At Location Tank 1 west, the contamination droppe~.~-~:~.Q ppm @ S feet. This appears to also be consiste~'t~ a small '~pill. T.he results of testing at Tank 2 west indi(bate a normal shape plume originating at Tank 1 west and .spreadih~downw~_~i.n""the shape of an inverted parabola of revolution. The sample at Tank 2 west @ 2 feet of 67 ppm is apparently'from vapors of the plume, 'or possibly some movement upwards by capillary attraction. Groundwater below the site lies 300-350 feet below the surface. Soil types are, as previously discussed, composed of sands, cobbles, boulders and ~ossibly layers of clay and silt. This formation is known as the "Kern River Formation". Mitigation of contaminants through the coarse soils would be, of course, rapid and nearly vertical until a less permeable layer is encountered. At that point, the migration would continue horizontally and vertically depending on the permeability, and dip of the formation and other factors as well. A large quantity of gasoline would be required to reach this. depth unless another mode of transport such as leaching was present. All indications are that the ground surface has been sealed since the beginning of the station's operation. EXcept for the possibility of broken water lines or a private sewage disposal near the contaminated area, no mode of transport other than gravity acting on the fluid itself is evident. Based upon the available information, the-Pikelihood of any gasoline reaching the groundwater i,~--extremely small. Action levels for groundwater depths in excess ~{ 100 feet are given as 1000 TPH. This number is stated as conservative by~-th-~'-'Task Force. Although levels at the two locations exceed 1000 TPH, the potential for migration can be virtually eliminated by mitigation measures.

Limitation~i The size of the site, and the.existing structure on the adjacent property to the east will limit the depth we will be able to reach. The soil is known to be very unstable which results in an excavation much larger than the contaminated area. There exists the possibility that the contaminated soil will be spread over a larger area as the excavation becomes wider and deeper. It would be impractical and uncertain to screen bucket loads for' stockpiling or disposal. The overburden on the tank area would have to be removed to gain access to the contaminated soil below the tank bottom. Again, this will limit the extent of the excavation and result in digging up most of the lot. Vapors excaping from the ground will pose hazards. Breathing devices will be necessary for workers working near the excavation. Depending on the amount of gasoline present and the atmospheric conditions at the time, explosive concentrations may accumulate. · This will necessitate monitoring while excavating. Persons directly down wind may be exposed to vapors from the excavation. It may be necessary to courdon off the area down wind and advise others nearby to stay indoors. The cost-effectiveness of this measure is largely dependent on its success. The.estimate we have prepared indicates'it will be very expensive. The major drawbacks of this alternative are its Kern Co. Health De' Page 5 February 24, 1988 uncertainties; these being total cost and overall success, and solution of the problem or possible contribution to it. II. ~por Extraction: Minimum: 'Cost Estimate $50,000.00 Benefits: Allows removal of volatile hydrocarbons from the soil in place. Limitations: Vapor extraction has been used successfully, but is'st'ill considered experimental. The level of residual contaminants in the soil, could be reduced but not eliminated. The boulders and cobbles will make installation of the vacuum wells and vents difficult and costly.. The expense of this method and its limited ability to remove all contaminants limits its feasibility for this site. III.Contaminated Soil Left in Piacel Under this.ja'l-t&rnAtiye, the existing structure would be removed . and the/fop 4 feet of the ground would be excavated and removed to a n~arby site where it would be mixed with a clay binder. The soil would then be returned to the site and compacted to 95% relative density. This will' render the top 4 feet impermeable. The site would also be graded to drain to the existing street flow lines. An in-place permeability test and laboratory air permeability tests will be taken to ensure a permeability of 'less than 10 cm/sec. The excavation plan and test results will be submitted to the Health Department for approval prior to commencement of the wor~. A deed restriction will be executed to ensure the following: 1. Future owners are aware of the presence and nature of the contamination. The impermeable barrier be left intact or replaced if development disturbs it. No man-made conduits.penetrate the layer unless they are designed to prevent infiltration of water. Kern Co. Health De 'Page 6 February 24, 1988 Monitoring systems ensure that all sewer and water lines do not leak. Sewer and water lines be double encased. All surface drainage water to be directed off-site.

Health Dep Page 7 February 24, 1988 Benefits: This alternative provides a practical method of isolating the contaminated soil from the primary mode of transport. By constructing an impermeable layer, surface waters cannot enter the soil and leach contaminants into the groundwater. The groundwater recharge potential is very low to begin with in consideration of the climate here in Bakersfield. The deed restrictions are intended to inform future owne?s and provide a mechanism by which future development can safely be accommodated. Mainly, this is an affordable alternate that maintains environmental quality without posing an unnecessary economic. hardship on the present owner. Limitations: The potential for fu~er contamination; although minimized, will still exist U.~_er-.~hi_s alternative. The degree of control that deed restrictions will offer over future development is somewhat uncertain, e DISCUSSION OF ALTERNATIVES The primary objective of the clean-up effort is to eliminate all contamination. If'this is not p6ssible, we shift toward protecting the environment to the extent possible with the financial and technical resources available to do the job. Alternative No. I has a good chance to reach the primary goal. Should it fail, the secondary goal may be jeopardized due to lack of resources. The cost estimate for Alternative No. I is based on a 20' x 20' x 20' area being hauled off. Should this area end up being 30' x 30' x 30', we would be looking at a 200% increase in cost. Our problem with this is where does it end? Are we exhausting resources while not being certain that the primary 'objective will be met. Alternative No. II has no chance of meeting the primary objective of removing all the contamination. It would remove most of the volatiles, but not the organic lead. The cost of this alternative.is highly uncertain because of the site soil conditions and unknown e~tent of the contamination. Alternative No. III skips the primary objective and proceeds directly with ensuring protection of the environment by isolating · the contaminants. The costs of this alternative are essentially fixed. The overall result is more certain. Kern Co. Health Page 8 February 24, 1988 CONCLUSION It is very unl..i~t-y.--that the contamination at the site is an immenent threat to.. g' JJ JJ er if water is prevented from entering the soil. The .limited data we have indicates that the spills are relatively small. The data is not'in any way conclusive, but it should be considered in the overall picture. The three alternatives give varying degrees of environmental projection with none giving absolutely certain results. It is our belief that the prudent choice of action should provide the necessary environmental protection at the lowest cost. Alternatives I and II are simply too unpredictable in terms of cost and overall result. Alternative III provides,~ in our opinion, the most protection per dollar with the techniques available to us at this time. Our firm and our client would like to meet and discuss what direction you would like us to proceed. If the Health Department feels Alternative III is sound in concept, we will proceed with providing detailed plans and material specifications for your review and discussion at the meeting. We look forward to a meeting with you at your earliest possible convenience. Respectfully submitted, PATRICK & HENDERSON, INC. Allan P. Henderson Civil Engineer JBM:ds Attachments Kern Co.

An address for 010raining the name and address of certified labs in different parts of California is listed in Appendix B. b) Instructions Soil samples should be taken one or two feet below the bottom of the backfill at suspected worst-case locations. Worst case locations include: 1) areas around the tank and piping, or where they used to be, that record the highest. readings with'.vapor monitoring'instruments; 2) areas around the tank and piping, or where they used to be, that look stained or discolored; 3) the lowest point of the tank, if this can be readily determined; and 4) where the tank meets the piping. At least two soil samples, one from either end of the tank, should be taken for each tank-suspected of leaking at a site. 2. Do BTX&E or TPH Levels Exceed Limits? a) Evaluate Laboratory Analyses for BTX&E 1) Explanation The followings, points about chemical analyses for fuel constituents should be kept in mind. First, benzene is the primary fuel constitueht of concern, because it is a known carcinogen and highly mobile at depths in soil where it cannot volatilize. It also has high water solubility. Second, benzene can volatilize at or near the surface and migrate to ground water if confined beneath the ground surface. Therefore, the absence of benzene in soil at an excavation does not rule out the presence of the less mobile fuel constituents: toluene, xylene and ethylbenzene. Furthermore, the absence of benzene in samples collected beneath a tank does not preclude its presence at greater depth. Chemical analysis must cover all of these constituents to verify the lack of contamination. Scil samples should be quantitatively analyzed fcr benzene, toluene, xylene and .ethylbenzene (BTX&E) using EPA Method 8020. All results should be reported in parts per million, either milligrams of fuel constituents per kilogram-of soil (mg/kg) or in CATEGORY 2 - SITE INVESTIGATION KNOI,~ OR SUSPECTED SOIL CONTAMINATION TREAT/R£HOVE I MINOR SOIL CONTAM[NAT ]ON ~ I GENERAL RISK AI~RAISAL (BASED : CN PROFILE OF ~3IL '' I:Z:)NTA~]NAT ION AND YES NO .

The site is situated in the northwest quarter of Section 18, T.29S., R.28E., M.D.B.& M. at the south- east corner of Panorama Drive and River Boulevard (see Figures ! and 2}. The site is currently used as an automotive smog-check shop. The general area is mostly residential. A liquor store is located just east of the. site (see Figure 2). A cemetery is located to the west of the site and bluffs of the Kern River are located to the north (see Figure 1). The facility permit number is 080003. The site was utilized as a gasoline station from 1960 to 1986 when it was permanently closed as a gasoline station. The ~tation operated under the Union Oil Company name from 1960 to 1980 and then under the Mobil name from 1980 to 1986. Four underground'storage tanks were removed from the property in December 1986 by Mundorf Construction. Two gasoline tanks, a waste oil tank, 'and a heater oil tank were situated on the property approximately as shown on Figure 2. The gasoline tanks reportedly had a capacity of '6,000 gallons, however, the tank dimensions, as shown on the original site maps, indicate a capacity of about 8,500 gallons.

Product lines and tanks removed in December 1986. 2. Tank 1 and Tank 2 were 6,000 to 8,500 gallons and used for gasoline storage. 3. Tank 3 was a 200 gallon waste oil tank. 4. Tank A was a 200 gallon heater oil tank. tanks had a capacity of 200 gallons each. ~e product lines ran between the tanks and dispenser islands approximately as shown on Figure 2. No'information is available regarding the condition of the tanks upon removal. The locations of the tanks and product lines, as shown on Figure 2, are based on previous work by another consultant. There are no known reports of discrepancies or reportable varia- tions in inventory monitoring, failed tightness tests, repairs to · tanks or piping, or past leaks. SITE GEOLOGY According to the Geologic Map of California, Bakersfield Sheet, the sediments underlying the site consist of Pliocene-Pleistocene nonmarine sedimentary deposits of the Kern River Formation. These deposits consist of poorly bedded to massive, unconsolidat- ed to loosely consolidated, very poorly sorted subrounded boul- ders and cobbles in a sandy gravel matrix. According to the General Soil Map of Kern County, published by the Soil Conservation Service, U.S.D.Ai, the site is underlain by soils of the Delano-Cuyama association. In general, these soils consist of well drained moderately fine textured soils developed from mixed rock sources which were deposited on old alluvial fans. 2 Based on the 19 Report on Water Condition§, Improvement Dis- t~ict No. 4, published by the Kern County Water Agency, the depth to groundwater beneath the site is approximately 250 feet. No perched groundwater is known to exist beneath the site. Several test holes have already been drilled at the site. Sandy gravel with abundant cobbles was encountered in the test holes. The deepest test hole was abandoned at a.depth of 75 feet. The sediments were fairly uniform to this depth. Test hole logs are included in Appendix A. Exposures Of the Kern River Formation in the bluffs of the Kern River just north of the site indicate that this formation is more than 200 feet thick beneath the property. PRELIMINARY SITE ASSESSMENT RESULTS The analytical results and chain of custody record from the preliminary site assessment are included in Appendix B. Eighteen \ soil samples were collected by Patrick and Henderson, Inc. and submitted to SMC .Laboratory for analyses. Samples associated with the gasoline tanks 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. Samples associated with the heater oil tank were analyzed for oil and grease. The T.O.X. and total lead analyses were performed by B. C. Laboratories. The sample locations are shown on Figure 3. Sample TI West @ ~' was collected at a depth of 2 feet beneath the west end of Tank 1. This sample reportedly.contained 1,880 L-J L-..l / I 1-/~UOR ppm T.V.H. and gh levels of B.T.X.& E. Sample T1 West @ 6' was collected f}om the same location at a depth of 6 feet beneath the · tank. This sample reportedly contained 1,370 ppm T.V.H. and high levels of B.T.X.& E. Sample TI East @ 2' was collected at a depth of 2 feet beneath the east end of Tank 1. This sample reportedly contained 10 ppm T.V.H. and traces of o-xylene and isopropylbenzene. Sample Ti East @ 5' was collected from the same location at a depth of § feet beneath the tank. This 'sample repor,tedly contained 7.9 ppm T.V.H. and traces of o-xylene and isopropylbenzene. Sample T2 West @ 2' was collected at a depth of 2 feet beneath the west end of Tank 2. This sample reportedly contained S7 ppm T.V.H. and low levels of B.T.X.& E. Sample T2 West @ 8' was collected from the same location at a depth of 8 feet beneath the tank. This sample reportedly contained 233 ppm T.V.H. and moderate levels of B.T.X.& E. Sample T2 East @ 2' was collected at a depth of 2 feet beneath the east end of Tank 2. This sample reportedly contained 5.9 ppm T.V.H. No B.T.X.& E. was detected in this sample. Sample T2 East @ 8' was collected from the same ,location at a depth of 8 feet beneath the tank. This sample reportedly contained 2.0 ppm T.V.H. No B.T.X.& E. was detected in this sample. Sample T3 @ 2' was collected at a depth of 2 feet beneath the bottom of the waste~oil'tank. This sample reportedly contained 135 Ppm oil and grease and 2.91 ppm total lead. Sample T3 @ 8' was collected at a depth of 8 feet beneath the waste oil tank. 4 This sample rePortedly contained.209 ppm oi mnd grease and 10.2 ppm total lead. No T.O.X. was detected in ei.ther of thgse samples. Sample T4 @ 2' was collected at a depth of 2 feet beneath the heater oil tank and reportedly contained 135 ppm oil and grease. Sample T4 ~ 6' was collected at a depth of 6 feet beneath the heater oil tank and reportedly contained 145 ppm oil and grease.. Sample L-1 @ 2' was collected at a depth of 2 feet beneath the product lines at sample location L-1 (see Figure 3). This sample reportedly contained 12 ppm T.V.H. and traces of benzene and toluene. Sample L-i @ 6' was collected from the same location at a depth of 6 feet beneath the'product lines. This sample report- edly contained 4.5 ppm T.V.H. and traces of toluene. Sample L-2 @ 2' was collected at a depth of 2 feet beneath the product lines at sample location L-2 (see Figure 3).. This sample reportedly 'contained 3,115 ppm T.V.H. and very high levels of B.T.X.& E. Sample L-2 @ 6' was collected from the same location at a depth of 6 feet beneath the product lines. This sample reportedly contained 1,126 ppm T.V.H. and high levels of B.T.X.& E. Sample PI #1 @ 2' was collected at a depth of 2 feet beneath grade level along the south edge of the northern dispenser island (sample location PI-1 on Figure 3). This sample reportedly contained 5.5 ppm T.V.H. and traces of xYlenes. Sample PI #2 @ 2' was collected at a depth of 2 feet beneath grade level along .the south edge of the s6uthern dispenser island (sample location PI-2 on Figure This sample reportedl~ ~ined 2.3 ppm T.V.H. and traces of~toluene and x¥1enes. Six foot samples at the dispenser islands were not collected because of difficult sampling, conditions. . These results indicate the'following: (1) significant gasoline contamination beneath the west end of Tank 1, (2) minor oil and grease contamination beneath the waste oil and heater oil tanks, and (3) significant gasoline contamination beneath the product lines in the vicinity., of sample location L-2 (see Figure 3). SOIL SAMPLING Pro~ress Report , Three test holes were drilled at the site on July 2, 1987 under the supervision of Patrick and Henderson, Inc. The locations of Test Hole Nos. 1-1, 1-2, and 2-1 are shown on Figure 4. The following discussion on these test holes is based on a report by Patrick and Henderson, Inc. dated February 24, 1988. These test holes apparently were drilled with a bucket auger drilling rig. Test Hole No. 1-1, located near the west end of Tank 1 (see Figure 4), was drilled to a total depth of 20 feet. Loose, sandy backfill was encountered from the surface to total depth. Hydrocarbon odors' in the s0il were noted to a depth of at least 15 feet.- Soil samples were coliected at depths of 10, 15, and 20 feet. The hole collapsed at the 20 foot depth and was abandoned. r-~ r-'1 ~ ' L I',,NX 2 , 'TT. ,~. ,¥o. I-2 1 TEST HOLE LOCATION Test Hole No. then drilled about 1 west-southwest of T.H. No. 1-1 (see Figure 4). This hole was abandoned at 4 feet because of difficult drilling conditions, Test Hole No. 2-1 was then drilled in the vicinity of the product lines east of the southern dispenser (see Figure 4). This hole also encountered drilling refusal at a depth of 4 feet. Strong hydrocarbon odors were noted. A backhoe was then utilized.to extend the total depth to 8 feet. A soil sample was collected at 6 feet and very strong hydrocarbon Odors were noted at 8 feet. The hole was abandoned at 8 feet because of collapsing sidewalls. Because hydrocarbon odors were noted in all of the samples collected from these test holes, no samples were submitted for laboratory analysis. A simplified log of T.H. Nos. 1-1 and 2-1 is included in Appendix A, ~page A-1. Subsequent to the drilling of T.H. Nos. 1-1, 1-2, and'2-1, William H. Park and Associates (now Duane R. Smith and Associ- ates) was retained to continue characterization of the site. Three additional test holes, .T.H. Nos. 1, 3, and 3A (see Figure 4}, were drilled in an attempt to characterize the contamination and to assess drilling capabilities in the rocky sediments beneath the site. The numbering scheme resulted from a previous work plan. Ail of the test holes proposed in the previous work plan were not drilled, however, the Original Proposed test hole numbers were retained. Several soil samples were submitted to SMC Laboratory for analyses. Test Hole No. 3A was drilled on May 2, 1989 Oust west of Tank 1 (see Figure 4). It was drilled to a depth of 22.5 feet with a hollow-stem continuous flight auger rig. Drilling refusal occurred at 22.5 feet where the hole was abandoned. ~Soil samples were collected at depths of 10, 15, and 20 feet for field screen- ing, but were not submitted for laboratory analysis. Field screening indicated the presence of hydrocarbons from. a depth of about 10 feet to total depth (see Appendix A, page A-4). Test Hole No. 3 was drilled on July 13, 1989 about 5 feet west of T.H. No. 3A (see Figure 4). It was drilled to a depth of 32 feet with an air rotary rig using mud mist. This boring was drilled using air'circulation only until the formation began to collapse into'the boring. Light bentonite drilling mud was then sprayed on the boring sidewall in an attempt to hold back the formation. Soil samples were collected at depths of 15, 20, and 30 feet and submitted 'for chemical analyses (see Appendix A, page A-5). No hydrocarbons were detected in the 15 or 2'0 foot samples (see Appendix C, page C-l). Traces of hydrocarbons were detected in the 30 foot sample (see Appendix C, page C-2). The boring was abandoned at 32 feet when the top of the boring began to col- lapse. Test Hole No. 1 was drilled on July 13 and 14, 1989 between Tank 1 and the product lines (see Figure 4). It was also drilled with an air rotary rig using mud mist when air circulation was no longer adequate.' Total depth of ~.H. No. 1 was 75 feet. Soil samples were collected where possible. The rocky formation 8 cannot be indisc Lely sampled without ying the sam- pling equipment. 'Suitable sample depths, as identified by the driller, resulted in the collection of samples at depths.of 30, 33, 41, 50, and 59 feet. Only the 33, 41, and 50 foot samples were deemed adequate for laboratory analysis (see Appendix A, pages A-2 and A-3). The 33 foot sample reportedly contained 1,600 ppm T.P.H. gasoline and high levels of B.T.X.& E. The 41 foot sample reportedly contained 1,700 ppm T.P.H. gasoline and high levels of B..T.X.& E. The 50 foot sample reportedly con- tained 560 ppm T.P.H. gasoline and moderate levels of B.T.X.& E. The analytical results of these three samples are included in Appendix C, pages C-2 and'C-3. Test Hole. No. 1 was'abandoned at a depth of 75 feet when the boring began to collapse. Field screening indicated the presence of. hydrocarbons to total depth (see Appendix A, pages A-2 and A-3), but the odors noted below 50 feet may have emanated from the boring sidewalls at lesser depths. Test Hole Nos. 1, 3, and 3A were backfilled with a cement-sand slurry from total depth to the surface. Contaminated drill cuttings and drilling mud, as identified by field screening, were placed in DOT drums and legally disposed. Supplemental Work Plan In a6cordance with a verbal agreement with the Department of Environmental Health Services, County of Kern, one additional deep boring is proposed. This boring will be drilled in .an attempt to determine the vertical extent of gasoline contamina- tiOn at the site. This test hole, designate~ .T.H. No. 2', will ~be drilled about 3 feet west of T.H. No. 1 (see Figure 4). This location may be altered slightly if shallow obstructions are ~ encountered. Underground Service Alert will be contacted prior to commencing drilling operations so that underground utilities in the ¥icinity 'may be marked. However, small on-site pipelines for which no documentation exists, may be present in. the subsur- face at the drilling location. The shallow soil at the drilling location will be probed for pipelines prior to the scheduled drilling day (tentatively set for November 12, 1990). Test Hole No. 2 will be drilled using a Drill Syst'ems AP-1000 dual-wall percussion hammer drilling rig using air as the only circulating medium. The proposed total depth of T.H. No. 2 is 150 feet, however, if field screening indicates that the vertical extent of contamination is less than 150 feet, the boring depth will be decreased accordingly. If field screening indicates contamination at 150 feet, a representative of the property owners will determine if the boring should be deepened or aban- doned. Since T.H. No. 2' will be located adjacent to T.H. No~ ! where a sample was collected at a depth of 50 feet, no attempt will be made to sample the first 50 feet of T.H.' No. 2. Soil samples will be collected where suitable, based on the judgement of the driller. However, the general guidelines for sampling will be at 5 foot intervals starting at a depth of 55 feet. Selected soil 10 samples will be ,mitred for chemical . 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 f~om SMC.Laboratory 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 through the dual-wall drill casing. The split- spoon sampler contains three or foUr two and one-half inches diameter by six inches long brass tubes. The sampler will be driven through the proper sample interval after the hole is drilled to a .suitable depth. 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 seal~ and polyethylene caps and then sealed with duct tape. The tube will then be labeled and placed in a polyethylene sample bag and the bag labeled and sealed. Each bagged tube will be retained in a chilled state on blue ice. Selected samples will be delivered to SMC Laboratory for analyses. Another soil sample 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, will be noted. 1! The results of field screening along with the soil descriptions will be recorded on test hole logs. The drill casing will be steam cleaned after drilling the bore- hole. The sampling equipment will be scrubbed, washed, and thoroughly rinsed between each sample collection to minimize the potential for cross-contamination. The test hole will be backfilled with a cement bentonite grout placed as the drill string is removed from the borehole. Contam- inated drill cuttings, as identified by field screening, will be placed in DOT drums for future treatment or disposal. The Health and Safety Considerations for this work plan are included in Appendix D. Submitted by: Duane R. Smith Registered Geologist Thomas F. Gutcher~ Staff Geologist PANORAMA.

During all operations that might release airborne vapors, an Hnu 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 and/or soil sampling operations will be suspended and the work 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. D-1 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 avoid hand and foot contact with contaminants. All. personnel will wear hard hats and ear protection when working near the drilli.ng rig. All supervisory personnel, involved in drilling and sample retrieval'have received training as specified in 'the OSHA Hazardous Waste Operations and Emergency Response Standard [29CFR1910.120]. The physical hazards associated with operating a drilling rig and sampling equipment must be recognized. Individuals not directly involved in drilling shall.stand back at least the distance of the vertical boom. A restricted access area will be~established around the work area as needed. An attempt will be made to contact local residents and businesses prior to drilling to inform them of the noise and possible ground-shaking associated with operation of the percussion hammer drill rig. If such complaints arise during drilling, they will be directed to the representatives of Kern County and the proper- ty owners. Drilling operations may be suspended until such matters are resolved. The potential hazards involved in the job will be reviewed with all personnel, including subcontract&rs, working on-site. Prior to commencement of work, emergency evacuation routes will be established. A "safe zone" location will be established taking D-2 into account weather conditions, site activities, and other factors, as necessary. Duane R. Smith and Associates personnel will coordinate activi- ties 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. HEALTH.
