Krumpler, Groundwater Resources, '[nc. (GR[) has been retained to perform some real estate assessment work on the above referenced property by Security Pacific National Bank, the current owner. Because the property was previously a gasoline station, GRI was asked to investigate the possible presence of gasoline contamination associated with that use of the property. Subsequently, a copy of the report to our client was sent to the Environmental Health Department with a request for a sign-off letter recognizing the abandonment in Place of' the storage tanks. In that report GEl concluded that there is no evidence of gasoline release to the soil under the property and that the tanks were rendered safe to the environment bv their abandonment in place. PuFsuant to a telephone conversation on June 19, 1989, ~n which you ..- and I discussed the Health Department's requirements for tank abandonment, GRI has collected soil samples from a boring north of -"~ii' the abandoned tanks and from borings at depths of 2 feet and 6 feet .-' .... beneath the dispenser island.

(GRI) supplements a previous Site Assessment Report for 700 Chester Avenue in Bakersfield, dated May 30, 1989. The additional site assessment work is described and the results of laboratory analyses are presented for soil samples collected on September 26, 1989.' During this investigation, no potential contamination derived from the storage and use of gasoline was identified in any of the samples retrieved a~ ~he site. 2.0 PROCEDURES Three borings have been made in addition to the sJx previously reported. Two are six feet deep in the dispenser island area and the third is a 30-foot deep angle-boring into the area between the building and the north end of the tanks.. Plate 2 (revised 10-27-89) is a plot plan illustrating all boring locations. The borings were drilled using six-inch diameter hollow-stem auger equipment. Drilling was performed by Melton Drilling of Bakersfield under ~he supervision of a GRI geologist. Cores were taken with a California Split Spoon Sampler. Soil from each core was screned with an HNu photionization meter, checked foF signs odor and discoloration and logged following the Unified Soils Classification System. The boring logs are provided in Plate 3. The undisturbed cores were contained in six-inch long, two and one- half inch diameter brass tubes and sealed using teflon tape and pasti¢ end caps. They were chilled and transported under a chain of custody to a state certified laboraotry for analysis. Augers and downhole dequipment, including coring devices, were cleaned between successive borings to avoid cross-contamination. The soil samples were analyzed by B.C. Laboratories of Bakersfield, California. Copies of ~he results of the sample analyses are lis~ed in Appendix A. All of the samples were ana.lyzed for benzene, toluene, ethylbenzene, and xylene using EPA Method 8020 and total petroleum hydrocarbons using methods outlined in the DOHS LUFT Manual. groundwater resources inc. SECURITY PACIFIC BANK 700 CHESTER AVENUE BAKERSFIELD, CA 3.0 DISCUSSION OF FINDINGS Soil samples were collected from two feet and six feet below the dispenser island identified by outlines the shape of a dispenser island between two concrete-slab driveways. Electric conduits and wiring were encountered dispenser locations, below which the soil samples were collected,. described as follows' DN-2 Sand, tan, fine-medium grained, loose, dry, no odor or stain (probably sand used in the construction/installation of the dispenser island). DN-§ Silt, brown, clayey, damp, no odor or stain (undisturbed soil). DS-2 Silt, brown, clayey, moist, no odor or stain (undisturbed soil). DS-6 Silt, as above (undisturbed soil). Laboratory analyses reported "none detected" for 9asoline constituents. The boring, B-7,. located near'the southwest corner of the building was angled 20 degrees from vertical to pass eastward along the north end of the tanks. At a measured depth of 30 feet the boring had a lateral departure of 10 feet and a true depth of' 28 feet. Pla~e 3 is a Log of Boring B-7. No gasoline constituents were reported by the laboratory; the lab results are attached to this report. 4.0 CONCLUSION AND RECOMMENDATION The results of this investigation support those of the previous report in that nothing was found to indicate contamination from the abandoned tanks or dispensers. No further assessment is indicated. groundwater .resources inc.

The property was originally a gasoline station, according to a document by E.R.T. (copy enclosed) which describes the basic method of gasoline tank abandonment as well as much of the subsequent history of the property. A report to our client (also enclosed) describes GRI's investigation of the soil beneath the property as related to its former use as a gasoline station. We conclude that the tanks were rendered safe to the environment by their abandonment in place and that there is no evidence of a gasoline release to the soil under this property. If you agree, will you provide a sign-off letter recognizing the abandonment in place?

'Re: Preliminary Hazardous Waste and Petroleum Hydrocarbon Site Assessment of the Bakersfield Property. ERT, Inc., A Resource Engineering Company, is pleased to submit its preliminary assessment of the abOve-referenced property. This evaluation was performed pursuant to your written authorization of November 24, 1987. We understand that you are the seller in this financial transaction. The following paragraphs summarize our initial findings, provide recommendations regarding the need for future investigative activities, and discuss study limitation. Site Location and Description The subject site is improved land situated at the corner of 7th Street and Chester Avenue in the City of Bakersfield. The property contains one vacant building previously used as a car stereo shop. No manufacturing or significant waste- generating activities currently take place on the subject property. Summary. of ¥indinqs The details of the scope of our investigative efforts, including major findings, are presented below. A complete list of references utilized in the preparation of this report is attached. Ms. Ann Cornell December 23, 19B7 Security Pacific 2 Based upon our historical research; review of governmental waste incident data bases and flies; and interviews conducted with selected individuals and public officials, no direct evidence was found to indicate that there is'or has been a significant contamination problem on or affecting the subject site. However, during the course of'our investigation, we identified several sources of potential concern. '~ ' The subject property was previously owned by Richfield Oil Company~ and used as a service station. Located at the station were three underground storage tanks containing gasoline and waste motor Qil. The station was reportedly abandoned in approximately 1969. At this time the property was purchased by Mr. Merlin Frasch and leased to an upholstery shop. When Mr. Frasch sold the property in.1972, .i~ he had the underground storage tanks filled in-place with a concrete slurry. The local Fire Department was reported to be on site during the filling of the tanks. This tank abandonment procedure was .conducted. under the proper reou.latory guidelines requi~ed at the time.._ Collection of soil samples was not. required and there are no records of the tank abandonment on file with either the Kern County Department of Health Services or the Bakersfield Fire Department. Records on these activities have only been kept at these agencies since 1985 and 1973, respectively. If leakage from the tanks had occurred while in operation, there is a very low probability that contamination still exists beneath the site. This opinion is based on similar experiences, and information concerning the existing local soil and groundwater conditions, which would tend to promote volatilization and natural biodegradation of any leaked fuels over the fif=een years'since abandonment. Specifically, the site is underlain by porous sands, silts and gravels deposited by the ancestral Kern River. Depth to groundwater is estimated to be 170-180 feet, according to the Kern County Water. Agency. These factors present optimum conditions for the breakdown of petroleum hydrocarbons. In view of the above considerations, we are of the opinion that the subject site Dresents a relatively low level of risk i n ' terms o f ..~h~_ _]?g~eP~....._]~r_e~en~e , --of a s igni f~ant contamination problem resulting from hazardous materials or Ms. Ann Cornel1 December 23, 1987 Security Pacific 3 petroleum hydrocarbons as defined under applicable federal and state environmental laws. This opinion is based upon our professional judgement of the facts and' other pertinent information collected as part of this investigation. ~ec°~mendations. ERT's preliminary conclusions, as described above, cannot be verified without undertaking an analytical testing program. While the final decision to conduct additional investigative ac=ivitieu ~ill be dependent upon the buyer's and seller's respective assessment of the business risks involved, ERT does not believe that the p~rformance of additional ~ a~9~vities, incl~di~q the implementation of an analytical testing pro~ram, are warranted at thi~' time. ..~. . If further investigation is required, ERT recommends "the collection of soil samples beneath and/or around the tanks. The samples should be analyzed for constituents stored in the tanks to verify the presence or absence of contamination associated with possible past tank failure. Study Limitations This report, including the exhibits attached thereto, describes the results of ERT's initial investigation to identify the potential presence of a significant contamination problem involving or affecting the subject property. The conclusions and recommendations stated herein represent the application of a variety of engineering and technical disciplines to material facts and conditions associated with the subject property. Many of these facts and conditions are subject to change over time; accordingly,- the conclusions and recommendations must be viewed within this context. We note that the investigative activities took place between December 1 and 15, 1987. ERT has performed this preliminary assessment in a professional manner using that degree of skill and care exercised for similar projects under similar conditions by reputable and competent environmental consultants.

(GRI) describes'a site investigation and presents the results of soil samples taken at ~ ._ 700 Chester Avenue in Bakersfield, California, on May 12, 1989. During this investigation, no potential, contamination derived from the storage and use of gasoline Was identified in any of the samples retrieved at the site. ~' "' · 2.0 BACKGROUND AND FINDINGS .. . Site usage has' inCluded a Richfield Gasoline Station, a restaurant, and, more'recently, a car audio service store. Real Estate records indicate that three gasoline tanks were abandoned in place using a slurry mix in 1969. The City of Bakersfield Fire Department1 (prior lead agency 'in underground tank abandonments) has no written record of this action and the Kern County Environmental Health Department2 (present lead agency) has no written record of any tanks located at the site. 3.0 PROCEDURES Six borings were drilled to sample the soil at the site. Plate 2 is a plot plan illustrating their locations. The borings were drilled using six inch diameter hollow stem auger equipment. Drilling was performed by Melton Drilling of Bakersfield under the supervision of a GRI geologist. Cores were taken with a California Split Spoon Sampler.' Soil from each core was screened with an HNu photoionization meter, checked for signs of odor and discoloration and logged following the Unified Soils Classification System. The boring logs are provided in 'Plate' 3. The undisturbed cores were contained in six-inch long, two 'and one-half inch diameter brass tubes and sealed using teflon tape and plastic end caps. They were chilled and transported under a chain of' custody to a state certified laboratory for analysis. Augers and downhole equipment, including'coring devices, were cleaned between successive borings to avoid cross-contamination. 4.0 LABORATORY ANALYSIS OF SOIL SAMPLES The soil samples were analyzed by B.C. Laboratories of Bakersfield, California. Copies of the results of the sample analyses are listed in Appendix A. groundwater resources inc. sEcURITY PACIFIC BANK 700 Chester Avenue All of the samples were analyzed for benzene, toluene, ethyl benzene, and xylene using EPA Method '8020 and total petroleum' '" hydrocarbons using methods outlined in the DOHS LUFT manual, i. 5.0 GEOLOGY AND HYDROGEOLOGY · ' This site is 'located in the southern end of the San 'Joaquin ...-' ... Valley. Sediments of the area are composed of ·alluvial deposits ....~. of the Kern River derived from the granitic Sierra Nevada terrain lying to the east. Soils encountered during 'the boring process were composed of predominantly fine to medium grain silty'.sand· containing abundant micas,.. · ........... ' The depth to groundwater in the.vicinity of the site approximately 175 feet.~ This area is classified as "No'n ' .' Environmentally Sensitive by the Kern County Environmental Health Department. '.. · 6.0 DISCUSSIONS ~ .. An inspection was made of the ~rounds and the building at the site. No soil discoloration or obvious signs of surface contamination was observed. During this initial investigation, the location of the underground storage tanks could not be found. Characteristic features, such as vent pipes, fill boxes, and sub-pump boxes, are either covered over with asphalt or no lgnger present at the site. A Fisher M-Scope metal detector was then utilized to find the tanks. Two large rectangular areas were delineated in the front of the property paralleling Chester Avenue using this device. Boring B-1 and Boring B-2 were each drilled at a 30 degree angle to a total measured depth of 30 feet and a true vertical depth of 26 feet (Pla=e 2). The total lateral extent of each of these borings is 15 feet northward. The soil from these borings was logged as having no odor or discoloration and the soil sample analysis results were reported as "Non Detected" fo'r all constituents. A sounding rod was driven five feet into the subsurface to confirm the presence of tanks in the area delineated by the metal detector. The rod did not strike anything metallic indicating that the tanks were located elsewhere. groundwater resources inc. SECURITY PACIFIC BANK 700 Chester Avenue The auger rig was then utilized to make several spot borings to five feet in an effort to locate the tanks (Plate 2). A tank cluster was found on t. he south side of the property facing 7th Street. The cluster occupies an area approximately 25 feet by feet. It is possible for three 8,.000 gallon tanks to be located within this area. BoTing B-3 was drilled straight to a depth of 10 feet to 'define the eastern edge of the tank cluster. Boring B-4, Boring B-5, and Boring B-8 were each drilled at a 20 degree"angle to a ~otal measured depth of 30 feet and a true vertical depth of Z8.2 feet. Boring B-4 was augered westward 10.2 feet Placing it approximately 3 feet from the tank.'cluster~at 'total-depth. Boring B-5 was augered northward 10.2 ~:-feet placin'g'"it approximately five feet within the tank cluster at total"depth. Boring B-6 was augered 'eastward 10.2feet placing it approximately five feet within the tank cluster at total depth. The soil from these borings was logged as having no odor or discoloration and the soil analysis results were reported 'as "None Detected" for all constituents. · 7.0 CONCLUSIONS 7.1 A cluster of under,round storage tanks is .located on the south end of the property facing 7th Street. 7.2 There was no contamination found in any of the soil samples taken at the site. 7.3 There were.no obvious 'signs of 'soil discoloration or surface contamination identified at the site. 8.0 RECOMMENDATIONS 8.1 The Kern County Environmental Health Department should be.notified that underground storage tanks have been abandoned in place on the property. 9.0 REFERENCES 1) ' Personal communication with Jim Embry, Bakersfield City Fire Department, May 3, 1989. 2).
