90-045l - Blackberry Farm - Harding Lawson Associates - 3rd Party arbitrator to review reports regarding site conditions (x-ref 90-045d)Harding Lawson Associates May 15, 1991 91005,875.02 Blackberry Farm Recreation Center c/o Berliner, Cohen & Biagini Ten Almaden Boulevard, 1 1 th Floor San Jose, California 95113 Attention: Edward Malysz, Esq. Gentlemen: Proposal and Fee Estimate Blackberry Farm Review Cupertino, California City of Cupertino c/o Charles Kilian, Esq. 1740 Technology Drive, Suite 250 San Jose, California 95110 Attention: Charles Kilian, Esq. Harding Lawson Associates (HLA) is pleased to present this proposal and fee estimate to Blackberry Farm Recreation Center (Blackberry) and the City of Cupertino (City) to review a number of reports and provide conclusions and recommendations regarding site conditions at the Blackberry Farm, 21975 San Fernando Avenue, Cupertino, California (site). This proposal and fee estimate has been prepared in response to a letter submitted jointly by Blackberry and the City to HLA dated April 25, 1991. It is our understanding that Blackberry sold the site property to the City, and as part of the sale agreement, a "pre-closing" inspection was performed by a consultant retained by the City. The City's consultant concluded that concentrations of petroleum hydrocarbons and lead requiring remediation exist in the vicinity of Stevens Creek. Blackberry then retained the services of a second consultant to perform additional testing: Blackberry's consultant concluded that no significant concentration of petroleum hydrocarbons exists in the Stevens Creek channel. Subsequently, three monitoring wells were installed and sampled by a third consultant. Since the first two consultants do not agree on the presence of petroleum hydrocarbons and the need for remediation in the Stevens Creek channel, the City and Blackberry have agreed to jointly retain the services of HLA to review the consultant's reports and attempt to resolve the differences. HLA proposes to perform the following work items: o Review of reports supplied to HLA. Discuss by telephone with the City, Blackberry, and their consultants any additional information that may be available with regard to site conditions. o Meet, if necessary, with the parties to discuss site conditions. f_;,_pneenng and 6�,5 Rodv,ond BoOevai PO Be• 573 No.e!o C_ ).19a,y a17.892Ott2' Divromnental Services „� 11,1, •i�li, ��/ ll�r,�li� i I.,, � �� Harding Lawson Associates May 15, 1991 Blackberry Farm Recreation Center and City of Cupertino 91005,875.02 Page 2 o Prepare a report outlining conclusions and recommendations regarding site conditions and the need to perform further site investigations or remediation. HLA proposes to perform these services on a time -and -materials basis in accordance with the attached Service Agreement and Schedule of Charges. It is our understanding that the City and Blackberry will divide our fees and each party will pay one half of the incurred costs. HLA estimates the fee for the services outlined above to be as follows: Report Review $1,200 Phone Discussions 400 Meeting (if required) 750 Report Preparation 1,800 Total Estimated Project Costs $4,150 This estimate assumes that the reports and site information to be reviewed have already been submitted to HLA and no significant additions to this material will be made. This estimate also assumes approximately three hours of phone discussions, one two-hour meeting to be held in Cupertino, and the preparation of one letter report. This fee estimate does not include costs for additional site characterization or negotiations with regulatory agencies. HLA can begin work on this project after receipt of written authorization to proceed. If our proposed scope of services and fee estimate are agreeable, please return one executed copy of the attached Service Agreement as our notice to proceed. One Service Agreement is being submitted to both the City and Blackberry. If you have any questions regarding this proposal, please call me at 415/899-7308.

I. Background Information. Pursuant to the terms of that certain Contract for Purchase and Sale of Real Property dated February 4, 1991, as amended ("Contract"), Blackberry Farm agreed to sell the Property to City, and City agreed to purchase the Property from Blackberry Farm. In connection with City's pre-closing inspections of the Property, City engaged the Environmental Division of Carlos Aubain ("City's Consultant") for purposes of performing an inspection and various soils tests of the Property to determine whether any hazardous 17 0424058613001okv —1— q6_0It1 5s Harding Lawson Associates April 25, 1991 materials were present on the Property. Based upon the results of such testing, City's Consultant prepared a report entitled Soil/Groundwater Contamination Assessment at Blackberry Farm, a copy of which is attached hereto as Exhibit "B" ("City's Report"). City's Report indicates that (i) certain soil samples obtained from various areas of the Property, including the Stevens Creek Area, contained various concentrations of recoverable petroleum oils ("RPO's"), and (ii) certain soils samples obtained from the area of the Property at which an underground storage tank was located contained various concentrations of lead. Following receipt of City's Report, Blackberry Farm engaged the environmental firm of Levine -Fricke ("Blackberry Farm's Consultant") to review City's Report for purposes of providing a separate analysis of the test results obtained by City's Consultant. Based upon Blackberry Farm's Consultant's review of City's Report, Blackberry Farm's Consultant recommended that additional soils testing be conducted using alternative testing procedures in order to verify whether concentrations of RPO's were present in the Stevens Creek Area in excess of levels otherwise permitted under applicable laws and regulations. Thereafter, Blackberry Farm's Consultant obtained further soils samples from the Stevens Creek Area and tested the same for the presence of RPO's. Based upon the results of such testing, Blackberry Farm's Consultant prepared a report entitled Results of Soils Sampling and Analysis, Blackberry Farm Golf Course, a copy of which is attached hereto as Exhibit "C" ("Blackberry Farm's Report"). Blackberry Farm's Report indicates that only one soils sample obtained from the Stevens Creek Area contained a detectable amount (11 ppm) of petroleum hydrocarbons characterized as diesel. All other soils samples did not contain detectable amounts of petroleum hydrocarbons or motor oil. In addition to the soils testing conducted by City's Consultant, City engaged City's Consultant to install three (3) wells and to perform certain groundwater testing in the Stevens Creek Area. City's Consultant furnished the parties with a report prepared by Environmental Experts, Inc., the firm engaged by City's Consultant to perform such groundwater testing. A copy of said report is attached hereto as Exhibit "D" ("Groundwater Report"). Based upon the results of the Groundwater Report, City's Consultant concluded that the groundwater in the Stevens Creek Area did not contain concentrations of hazardous materials in excess of levels permitted by applicable laws and regulations. Prior to the closing of the purchase and sale transaction, the parties agreed that Blackberry Farm would excavate soils from two specific areas of the Property (identified in Blackberry Farm's Report and City's Report as Sites A2 -2F and C1-lF/2F) and remove the underground storage tank located on the Property. As of the date of this letter, Blackberry Farm's Consultant has excavated the \079\05861033.P50 17-042405861-001:kv -2- Harding Lawson Associates April 25, 1991 soils from said locations and removed the underground storage tank located on the Property. However, as a result of the conflicting testing procedures, test results, conclusions and recommendations set forth in Blackberry Farm's Report and City's Report with respect to the presence of RPO's at Sites C2 -1F, D1 -2F, E1 -2F, E3 -2F, E4 -2F in the Stevens Creek Area (which sites are identified in both Blackberry Farm's Report and City's Report) (collectively, "Disputed Items"), the parties and their respective consultants were unable to reach an agreement as to the extent of remediation work, if any, required in the Stevens Creek Area. The Contract provides that if the parties are unable to agree as to the extent of any remediation work required in the Stevens Creek Area, the parties are required to engage an independent consultant to (i) review City's Report and Blackberry Farm's Report and (ii) make written recommendations regarding the nature and extent of remediation work, if any, required under applicable federal, state or local laws, statutes, ordinances or regulations with respect to the Stevens Creek Area. Following such written recommendations, Blackberry Farm's Consultant is to prepare a remediation plan incorporating the recommendations of the independent consultant and, thereafter, Blackberry Farm is to perform such remediation work in accordance with such remediation plan and the terms and conditions of the Contract. The purchase and sale transaction closed on April 3, 1991. As a result of a subsequent sales -leaseback transaction, the Property was acquired by the Cupertino Public Facilities Corporation, which currently leases the Property to City. As Blackberry Farm and City are unable to agree as to the extent of any remediation work required in the Stevens Creek Area, the parties now desire to engage HLA as an arbitrator and independent consultant to perform the services more particularly described below. II. Description and Scope of Requested Services. A. Joint Engagement. Blackberry Farm and City desire to jointly engage HLA to perform the services described hereinbelow. Subject to Paragraph D below, Blackberry Farm and City will be jointly responsible for the payment of fees and costs charged by HLA in connection with such services. B. Qualifications of Independent Consultant. The services described hereinbelow are to be performed by a registered geologist or civil engineer of HLA with experience in site assessment work, soils testing and remediation work. The geologist or civil engineer should also have experience with respect to arbitration and/or dispute resolution situations. \079\05861033.P50 17-042405861-001:kv -3- Harding Lawson Associates April 25, 1991 C. Initial Meeting. Following the designation of a geologist or civil engineer of HLA to perform such services, HLA should contact Edward Malysz at Berliner, Cohen & Biagini (telephone number (408) 286-5800) in order to establish a mutually convenient time to discuss with Blackberry Farm and City and/or their respective attorneys any additional information required by HLA to perform the services described herein. D. Written Estimate. Following the initial meeting with the parties, HLA should prepare a written estimate of fees and costs to be charged by HLA in connection with the services described herein and submit said estimate to each party for its review and written approval. E. Review of Reports. Following approval of the written estimate, HLA is to review City's Report, Blackberry Farm's Report and the Groundwater Report as the same relate to the Disputed Items. The purpose of this review is to reconcile, discount and/or reject the results, conclusions and recommendations relating to the Disputed Items in order to determine the extent of any remediation work required in the Stevens Creek Area under applicable federal, state and local laws, statutes, ordinances and regulations with respect to the Disputed Items. F. Discussions. Following the review of the enclosed reports, HLA is to discuss with City's Consultant and Blackberry Farm's Consultant any questions HLA may have concerning the testing procedures, results, conclusions and recommendations set forth in said reports regarding the Stevens Creek Area. G. Recommendations. Based upon HLA's review of the reports and discussions with the consultants regarding the Disputed Items, HLA is to make recommendations regarding the Disputed Items and the extent of any remediation work required in the Stevens Creek Area under applicable federal, state and local laws, statutes, ordinances and regulations with respect to the Disputed Items. If HLA is unable to make such recommendations due to its inability to reasonably reconcile, discount and/or reject the results, conclusions and recommendations relating to the Disputed Items, then HLA is to determine whether further soils testing is necessary to reconcile the matters identified in the Disputed Items. HLA is engaged only for the purpose of making recommendations concerning the Disputed Items as the same pertain to the Stevens Creek Area, and HLA is not to comment nor make any recommendations concerning any matters other than the Disputed Items or any area of the Property other than the Stevens Creek Area. \079\05861033.P50 17-042405861-001:kv -4 - Harding Lawson Associates April 25, 1991 H. Report. HLA is to prepare a written report ("Independent Report") setting forth its recommendations regarding the matters identified in the Disputed Items and the extent of any remediation work required in the Stevens Creek Area under applicable federal, state and local laws, statutes, ordinances and regulations with respect to the Disputed Items, and to submit such written report to Blackberry Farm and City. If HLA recommends that remediation work should be performed in the Stevens Creek Area with respect to the Disputed Items, then the Independent Report should include sufficient information for Blackberry Farm's Consultant to prepare a remediation plan for the Stevens Creek Area in accordance with the terms of the Contract. If HLA recommends that further testing should be conducted to reconcile the matters identified in the Disputed Items, then the Independent Report should designate the locations at which further soils testing should be conducted and the testing methods which should be used in connection therewith. If HLA recommends that no remediation work should be performed in the Stevens Creek Area, then the Independent Report should clearly state that no such remediation work is necessary in the Stevens Creek Area. The recommendations set forth in the Independent Report will be conclusive between the parties as to the extent of any remediation work to be performed by Blackberry Farm in the Stevens Creek Area. I. Notices. All notices, reports and correspondence should be delivered to the counsels of the parties at the addresses set forth hereinabove. If the terms and conditions of this letter are acceptable to you, please sign the enclosed copy of this letter and return the same to Edward Malysz at Berliner, Cohen & Biagini. We look forward to engaging your firm to perform the services described hereinabove. As the parties are interested in completing this phase of the transaction as soon as possible, please consider the above information at your earliest convenience.

Box 580 Cupertino, CA 95015 Re: soil/groundwater contamination assessment at Blackberry Farm, Cupertino, California Dear Mr. Viscovich: The Law Offices of Carlos A. Aubain, is a specialized environmental company which participates in the collection and interpretation of soil samples and provides opinions and proposals for further investigation or remediation activities. This report describes environmental sampling and documentation performed by our firm on this project. In addition to the sampling report text itself, supporting documents are provided as attachments. These will include the chain of custody and the certified laboratory report. For personal reference all these documents should be kept together and preserved as a file of interrelated records which comprise the documentation of the work performed at this site. SCOPE OF WORK PERFORMED The Law Offices of Carlos A. Aubain was retained to assist the City of Cupertino assess the present and/or potential environmental contamination at a 33 acre improved land parcel commonly known as the Black Berry Farm. The property is currently, and has been for the past 35 years the site of a golf course and picnic facilities; prior to that the area had a large conpentration of orchards and agricultural usage. The body of water known as Stevens Creek serves as a natural property boundary at the property's Westerly border. See appendix A for property and boundaries locations. On January 28, 1991 three field technicians and a registered environmental assessor were dispatched to the above mentioned site to identify and collect samples from fourteen previously selected locations (see appendix H). The criteria for selection was primarily based on a careful walk through of the property and information provided by the owner of the property, Mr. Nelson, and City of Cupertino staff members. Five distinct areas were identified as potentially contaminated and as being representative of the overall condition of the land. The first area tested was an open chemical storage behind a park maintenance building. This area was selected due to the storage of chemical substances in 55 gallon drums and general storage usage which includes asbestos containing products. Three samples were obtained at two feet from the surface and composited into one for laboratory testing. The sample was screened for total oil and grease, EPA method 503, asbestos, and industrial solvents. A sample from the inside of the maintenance building was also obtained and analyzed. The second area tested was beneath a 500 gallon, single wall, leaded gasoline, steel underground storage tank which is believed to be deteriorated due to its longevity. Two samples were obtained directly beneath the tank at both its east and west ends. A third sample was obtained at the juncture were contamination from this tank, if any, would meet the creek. All samples were analyzed for total lead content and total petroleum hydrocarbons with a BTEX distinction. The third area tested involved the survey of certain drainage pipes, ranging in size from one to five inches, which have been installed at various locations throughout the property and discharge into the creek. Three distinct locations were selected among a total of nine discharges located. All samples were tested for oil and grease 1 503 because of the odor and discoloration associated with that type of hydrocarbon contamination. The fourth area tested was a golf course maintenance structure were strong hydrocarbon odors were easily discernible and visual inspection appeared to indicate the presence of oil and grease in the soil. Two samples were obtained and analyzed for total petroleum hydrocarbons and BTEX content, solvents and oil and grease 1 503. The fifth area tested was a 800 feet segment of Stevens Creek which was selected for the environmental sensitivity as well as evidence of chemical'contamination in the soil. Four samples were obtained at intervals of approximately 200 feet. These samples were analyzed for total oil and grease contents and in addition one sample was analyzed for pesticide traces due to the historical use of this site. All samples were properly obtained and maintained. Adequate documentation was kept in the form of a chain of custody in accordance with all applicable Federal, State and local regulations. In addition to soil sampling our firm conducted a hazardous waste sensitivity study utilizing a HNU photo -ionizer model HW -101 which is capable of detecting concentrations of hazardous waste in soil. Because of its wide operational range this instrument is unable to confirm the existence of a specific chemical element but readily confirms the presence of contaminants in the soil even in minute concentrations (range is 0.1 ppm to 2000 ppm). SAMPLING PROTOCOL Our firm uses sample containers of the type specified by EPA or the RWQCB for the collection of samples at sites were hydrocarbon based contamination is suspected. Soil samples for volatile, semivolatile and nonvolatile analyses are all collected in properly prepared brass liners which are 2 1/2 inches in diameter by 6 inches in length. Closure is accomplished with press fit plastic end caps which are fitted to the open ends of brass tube liners after a sheet of aluminum foil is wrapped over the exposed sample material. A noncontributing-nonsubtractive tape is wrapped completely around the joint areas where the plastic caps meet the outer wall of the brass tube. No preservative other than cold storage is used on samples capture in sample containers of this type. Solid sample material is captured by advancing the liner into the soil. This is accomplished by removing 12 to 24 inches of soil from the surface and retrieving a representative "native" soil sample with the aid of a brass sleeve hammer or in some instances by directly retrieving said sample by pushing liner into soft soils. The open ends of the sample liner are covered with aluminum foil and plastic end caps. The excess aluminum foil is removed and the edge of the plastic end caps is tightly sealed against the outer surface of the brass liner with an unbroken wrap made with a tape which has been tested to confirm that it does not contribute compounds that would be detected in the type of analyses intended for the sample contained inside of the brass liner. The brass liner is then labeled with the appropriate identification numbers which specify the sampling activity designation number, sample collection area, depth etc. that apply to that particular sample. The sample liner is then placed in an ice chest which contains pre -frozen blocks of an inter ice substitute such as Blue Ice or Super Ice. CHAIN OF CUSTODY Samples are continuously maintained in either a chilled ice chest, refrigerator or freezer from the time of collection until acceptance by the State Certified Hazardous Materials Testing Laboratory selected to performed the analytical procedures. if the sample are taken charge of by a different party (such as another person from our offices, courier, etc.) prior to being delivered to the laboratory, appropriate release and acceptance of records are made on the chain of custody (time, date, and signature of person releasing the sample followed by the time, date, and signature of person accepting the samples). Following receipt of the samples and completion of the chain of custody form, the laboratory then assigns their own identification -numbers to the samples. Different laboratories use different numbering systems and, according to their own internal conventions may not assign sequential numbers to sample which are placed on temporary "hold" pending the results of other analyses. Laboratory identification numbers (if assigned and available) will be found on the certified analytical report by the laboratory. The certified analytical report generated by the laboratory is the official document in which they issue their findings. The certified analytical report is included as an attachment at the close of this report. ANALYTICAL FINDINGS All samples were analyzed at a State Certified Analytical Laboratory (certificate no. 145) in accordance with state and federal regulations. A copy of the chain of custody and analytical results is appended to this report as appendix C. No industrial solvents, pesticides or asbestos were found near or at the places tested; However the following contaminants were found at levels beyond the baseline standards set forth in the revised Regional Board Staff Recommendations, which require further soil/ground water investigation when: "The concentration of either total petroleum hydrocarbon and/or total oil and grease is greater than 100 ppm's in soil" The origin of the 100 ppm level was to create method to prioritize contaminated sites and indicate whether a significant volume of fuel had been released or discharged. The level of clean up is to be determined by assessing the potential impact of the contaminated soil on the environment. There are numerous factors, both universal and those unique to each site, that must be considered in developing a clean up plan which will ensure both regulatory compliance and limited future environmental liability. The reported oil and grease values show that high levels of contamination presently exist in at least the following areasi Area A: open chemical storage A composite sample of three areas, (see appendix B) revealed 120 parts per million of oil and grease and 35000 ppms inside storage room housing heavy machinery. Both areas are surfaced with asphalt and the contamination exists underneath the surface. Area B: underground storage tank Two samples were obtained from the eastern and western ends beneath the UTS. Though no hydrocarbons were detected, lead was found to be contributing to the chemical contamination of the immediate surroundings. Area C: drainage pipes discharging into Stevens Creek Three samples were obtained from randomly selected discharge pipes; nine pipes were observed which could potentially be contributing to chemical presence in the creek. Sample C3 had non-detectable amounts of oil and grease but samples C1 and C2 had extremely high oil contents of 650 and 2900 parts per million respectively. Area D: Golf course maintenance and storage room Two samples were obtained from the northern and southern walls of this structure. One of the samples was confirmed Positive for oil and grease and similarly various portable HW -101 tests detected the presence of hydrocarbons around the outside perimeter of this structure. Area E: Stevens Creek area Four samples were obtained and analyzed at a state certified laboratory; numerous other fields samples were conducted to correlate with the laboratory resulta; Based on these sampling events we are of the opinion that the entire length Of the creek, exoept for a few isolated locations, is contaminated with chains of petroleum hydrocarbons. Please note that at the time the sampling events were conducted the creek bed was dry; at present certain portions of the creek are under water and hence the areas that were considered to be uncontaminated at the time of sampling might have been adversely afttcted. RECOMMENDATIONS The recommendations contained herein are site specific contamination assessments based upon the analytical findings and environmental studies conducted at the Black Barry Farm in Cupertino, California. It is our professional opinion that at a minimum an immediate source removal of oil and grease contaminants be effected to mitigate the environmental damage and further percolation into groundwater of oil and grease and lead as reported above. We specifically cite the extreme sensitivity of the locale, i.e. Stevens Creek is affected by the high concentration of contaminants, and the fact that numerous readings taken by our portable HW -101 revealed elevated concentration of chemicals throughout the length of the meandering water bodies. It is our further opinion that the underground storage tank should be removed due to its evident metal fatigue and the fact that lead contaminants are present indicating structural unsoundness of such tank. At a minimum, due to its toxicity, the total lead present in the soil around the tank should be immediately excavated and removed from the site. It is wortnY of noting that the soil permeability at this location tends to be quite high due to the sandy nature of the creek and the numerous rocks and boulders encountered in its bed and hence it is our belief that this high soil permeability would contribute to percolation.

(Levine•Fricke), collected and analyzed soil and surface -water samples from the creek area at Blackberry Farm Golf Course in Cupertino, California ("the Site"; Figure 1). The approximately 33 -acre site is located west of Byrne Road, south of Stevens Creek Boulevard, and is bordered on the west by Stevens Creek (Figure 1). This report presents the scope and findings of the sampling and analysis program. The major objective of the sampling and analysis program was to evaluate the possible presence of petroleum hydrocarbons in soil in the area of Stevens Creek. Petroleum hydrocarbons (quantified as petroleum oil) reportedly were identified in soil samples previously Collected from the creek by Mr. Carlos A. Aubain of the Law Offices of Carlos A. Aubain. Mr. Aubain was retained by the City of Cupertino to perform an environmental assessment of the Site in connection with the city's potential purchase of the Site. Mr. Aubain collected and analyzed eight shallow soil samples from the creek area in January 1991. The results of these analyses, which were reported in a document written by Mr. Aubain entitled, "Soil/Groundwater Contamination Assessment at Blackberry Farm, Cupertino, California," dated February 8, 1991, indicated the presence of petroleum oil in concentrations ranging from less than 30 mg/kg (i.e., parts per million [ppm]) to 2,900 ppm. On the basis of these findings, Mr. Aubain recommended soils affected by petroleum oil be removed from the Site. Levine -Fricke was retained in February 1991 by Berliner, Cohen and Biagini ("Berliner") the attorneys for the site's current owners. Berliner asked Levine -Fricke to review Mr. Aubain's report and to assist them in developing an appropriate response to the reported petroleum -affected soil. Based on our review of Mr. Aubain's report, we were concerned that nstuxal organic (vogatativQ) mat -tor, which is abundant in 4 -ho soils in the creek channel area, may have been inadvertently characterized as petroleum oil by the analysis method used for 2299\SCM 1 0 131 91 14: 1 L='.AhiE FRI,_�•.E 007 Mr. AubainnIs samples (EPA Methcd 5520 E&F Gravimetric). Therefore, Levine•Fricke recommended in a letter dated February 14, 1991, collecting soil samples from areas Mr. Aubain had sampled previously and analyzing them using a different method (EPA Method 8015, characterizing for motor oil and diesel) to confirm the presence of petroleum hydrocarbons in soil in the area of Stevens Creek. 2.0 SCOPE OF WORK The Scope of Work for the sampling and analysis program included the following tasks. (1) Collection of samples at the following areas: + Six shallow soil samples were collected from the creek channel at areas where previous sampling reportedly identified the presence of petroleum oil. • Two shallow soil samples were collected adjacent to a maintenance shed where previous sampling reportedly identified the presence of petroleum oil. • Two surface -water samples were collected from the creek at locations adjacent to areas where previous soil sampling reportedly identified the presence of petroleum oil. (2) Analysis of all eight soil samples and both water samples for total petroleum hydrocarbons quantified as motor oil and diesel. (3) Data evaluation and report preparation. The Scope of Work for the sampling and analysis program was limited to the collection of shallow soil and surface -water samples at areas where soil sampling performed by Mr. Aubain reportedly identified petroleum oil. No evaluation was made of other on-site areas. 3.0 COLLECTION AND ANALYSIS OF SOIL AND SURFACE -WATER SAMPLES 3.1 soil Sample Collection On February 15, 1991, shallow soil samples were collected from six locations (LF -E4 -2F, LF -E3 -2F, LF -E1 -2F, LF -C2 -1F, LF -2-0.5, and LF -3-0.5) within the Stevens Creek channel 2299\SLM 2 LEVI N E•FRICKE (sample locations are shown in Figure 2). The first four of these samples corresponded to sample locations E4 -2F, E3 -2F, E1 -2F, and C2 -1F collected previously by Mr. Aubain and which reportedly contained petroleum oil concentrations of 520 ppm, 370 ppm, 290 ppm, and 2,900 ppm, respectively. Mr. Aubain was present during Levine•Fricke's sample collection and identified the locations where his samples had been previously collected. Where possible, Levine -Fricke collected soil ( samples within 2 feet of Mr. Aubain's original sample locations. However, two of the original sample locations (E1 -2F and C2 -1F) were found under water. Soil samples were therefore collected as close as possible to these locations ( (within approximately 10 feet), at areas approved by Mr. Aubain. Soil samples LF -2-0.5 and LF -3-0.5 were collected in the vicinity of C2 -1F (the previous sample having the highest reported petroleum oil concentration) to help assess the lateral extent of possibly affected soil. ( In addition, shallow soil samples were collected from two l locations (LF -D1 -2F and LF -1-2) adjacent to the golf course maintenance shed. A soil sample (D1 -2F) collected previously in this area by Mr. Aubain reportedly contained petroleum oil 1 at a concentration of 250 ppm. One soil sample was collected from each location at depths between 0.5 and 2 feet below ground surface using a hand auger l and a slide -hammer sampling tool. Soil samples were collected in clean, 2 -inch -diameter by 4 -inch -long brass liners. The ends of each liner were sealed with foil and plastic caps, labeled, and placed in a cooled ice chest. Prior to use at each location, sampling equipment was washed with Alconox (a laboratory -grade detergent) and rinsed with deicnized water. 3.2 Surface -Water Sample Collection Samples of surface -water from Stevens Creek were collected adjacent to soil sample locations C2 -1F and E1 -2F (SW -1 and SW -2, respectively). The samples were collected directly from the creek in clean, 1 -liter, brown glass bottles. The bottles were sealed with screw caps, labeled, and placed in a cooled ice chest. 3.3 Chemical Analyses The soil and surface -water samples were transported under chain -of -custody documentation to Friedman and Bruya, Inc., a California State -certified analytical laboratory in Seattla, 2299 SLM 0��/'01. °1 14:5_ L::III E FFIi=! E Washington. All samples were analyzed for total petroleum hydrocarbons quantified as motor oil and diesel using EPA Method 8015. 3.4 Results Of soil and surface -Water Analyses 009 A low concentration of petroleum hydrocarbons characterized as diesel (11 ppm) was identified in one of the soil samples collected adjacent to the maintenance shed (LF -D1 -2F). Diesel hydrocarbons were not identified in any of the remaining soil samples above the method detection limit of 10 ppm or in either surface -water sample above the method detection limit of 0.2 ppm. Motor oil was not identified in any of the soil samples above the method detection limit of 50 ppm or in either surface -water sample above the method detection limit of 0.2 ppm. Laboratory data sheets for the soil and surface - water analyses are presented as Appendix A. 4.0 CONCLUSIONS The results of the soil and surface -water sample collection and analysis program did not confirm the presence of petroleum hydrocarbons in soils in the Stevens Creek channel. A low concentration of diesel (11 ppm) was identified in one soil sample collected adjacent to the golf course maintenance shed. However, this analytical result is unlikely to be considered a significant environmental concern because of the low concentration of diesel, and because the soil where this sample was collected is not in contact with water flow in the creek. Petroleum hydrocarbons quantified as motor oil and diesel were not identified above method detection limits in the remaining soil or surface -water samples. 5.0 LIMITATIONS The observations and conclusions presented in this report are professional opinions based on the scope of activities and information obtained through the Scope of Work described above. opinions presented herein apply to site conditions at the time of our study and cannot apply to site conditions or changes of which we are not aware or have not had the opportunity to evaluate. Any conclusions drawn from these data rely on the integrity of the information available to Levine -Fricke at the time of the investigation, and a full and complete determination of environmental risks cannot be made. 2299\su+ 4 1/2 Project No. 22.99 ♦tw OIF(691 )tro 1 M4F Figure 1 ; LOCATION MAP SOURCE: Thorrat (kcA, mm.

ENVIRONMENTAL EXPERTS, INC. SUBSURFACE ENVIRONMENTAL INVESTIGATIONS BLACKBERRY FARM 21975 SAN FERNANDO AVENUE CUPERTINO, CALIFORNIA Prepared by: Environmental Experts, Inc. 2038 Admiral Place San Jose, California March 5, 1991 Subsurface Environmental Investigation Blackberry Farm 21975 San Fernando Avenue Cupertino, California Project No. 191-022 March 5, 1991 1.0 Introduction Environmental Experts, Inc. was retained to install three ground -water monitoring wells and perform the appropriate sampling and chemical analysis at the property identified as the Blackberry Farm located at 21975 San Fernando Avenue in Cupertino, California. The site vicinity map is presented in Figure 1, and the site plan is shown in Figure 2. 1.1 Purpose and Scope Ground -water monitoring wells installation was performed to: (1) address the concern of the presence of total oil and grease (TOG) at the site from previous shallow soil sampling, and (2) determine the presence of subsurface contamination, if any. The scope of work included the following tasks: • Installation, of three soil borings and ground -water monitoring wells. • Collection and analysis of collected soil and ground water samples. • Determine whether hydrocarbons are present in the subsurface. • Preparation of a technical report presenting the findings and recommendations of the study. 1.2 Site Location and Description The site is located at 21975 San Fernando Avenue in Cupertino, California. The site is mainly a golf course which also contains recreation and picnic areas. The Stevens Creek passes through the site. The site is bounded from all sides by residential houses. 1.3 Site Background The site background is based on information and reports prepared by Mr. Carlos A. Aubain,..dated February 8, 1991. The report describes previous soil sampling locations and laboratory results which indicated high levels of total oil and grease (TOG). TOG concentrations were found to range from non detected by the instrument used for analysis to 35,000 parts per million (ppm). The report indicated that no ground -water samples were obtained from the site for analysis. 2.0 FIELD METHODS The procedures and methods used during field activities were conducted in accordance with the applicable regulatory requirements established by the Santa Clara Valley Water District (SCVWD), the Regional Water Quality Control Board, San Francisco Bay Region (RWQCB-SFBR), and field procedures as described in the following subsections. 2.1 Permitting Prior to commencement of work and field activities, ground -water construction permits were filed with the SCVWD. A copy of these permits are included in Appendix A. 2.2 Soil BorincT Installations Four soil borings were drilled on the site with a B-41 drill -rig operated by Exploration Geoservices of San Jose, California. Soil boring MW -1 was installed on February 28, 1991. Soil borings MW -2 through MW -4 were installed on February 30, 1991. The total depths for the soil borings MW -1 through MW -4 were 20, 15, 8, and 28 feet, respectively. Soil boring MW -3 was backfilled with neat cement since there was a drilling refusal at 8 feet and no ground water was encountered. The locations for the soil borings are shown in Figure 2. Soil samples were collected at 5 -foot intervals and significant lithology changes using a split -spoon sampler lined brass sleeves. Soil samples retained in the brass sleeves were covered with aluminum foil, capped with plastic caps, sealed with tape, and placed immediately in a cooler with ice. Samples were then transported to a State -certified analytical laboratory with the proper chain of custody documentation. A description of drilling procedures, soil classification, and soil sampling protocols are included in Appendix B. ' 2.3 Ground -Water Monitoring Wells Construction The soil borings (except MW -3) were converted to ground -water monitoring wells MW -1 through MW -4. Wells were constructed of clean, 2 -inch diameter, flush threaded, Schedule 40 PVC blank casings and 0.020 -inch slotted casings. Well installation procedures and construction details are present in Appendix B. 2.4 Monitoring Wells Development and Samnlin Well development was conducted on March 1, 1991, using a 2 -inch bailer. Wells were developed by purging approximately 5 -casing volumes of water from each well. During purging, pH, electrical conductivity, and temperature were recorded. These parameters were allowed to stabilize, indicating that formation water had entered the well. Field observations during well development are present in Appendix C. Water samples were collected on March 2, 1991, following the purging of 3 to 5 casing volumes from each well. Well development and sampling procedures were conducted in accordance to SCVWD and RWQCB guidelines and standard protocol described in Appendix C. Water samples were collected in the appropriate containers and transported on ice to the analytical laboratory with the proper chain of custody documentation. 3.0 SITE GEOLOGY AND HYDROGEOLOGY This section presents a brief description of the site geology and hydrogeology. Since all wells were installed close to the Stevens Creek, shallow water table was encountered and the ground -water is believed to flow towards the creek. The unsaturated zone in all three wells consist of a sandy silt to silty sand layer. The saturated zone consists mainly of sandy gravel to coarse gravel. Ground -water was encountered in MW -1, MW -2, and MW -3 at depths of 7.45, 4.85, and 18.85, respectively. 4. ANALYTICAL METHODS AND RESULTS One soil sample was obtained from each monitoring well, few inches above the ground -water table. Also, three water samples were collected from the site from each well. All soil and water samples were analyzed for TOG and volatile organic compounds (VOC), full scan, using standard test methods of the U.S. Environmental Protection Agency (EPA). A listing of the analytical methods used is presented in Appendix D. 4.1 Soil Analysis Soil samples collected..from the site were analyzed separately for TOG, using EPA Test Methods SM -5520, and for VOC, using EPA Test Methods 8240. The results of the laboratory analysis are included in Appendix D. All samples did not contained any TOG or VOC. The only soil sample that contained VOC constituents (acetone) is the soil sample collected from MW -4. 4.2 Ground -Water Analysis All ground -water samples collected from the site were analyzed for TOG, using EPA Test Methods SM -5520, and VOC, using EPA Test Methods 624. The results of the ground -water samples indicate the presence of methelene chloride.

PAUU50"s WAD FIELD PROCEDURES, BORING LAGS, AND WELL CONSTRUCTION DETAIIS GENERAL FIELD PROCEDURES, BORING LOGS, AND WELL CONSTRUCTION DETAILS A description of general field procedures conducted during the investigation is presented below. Also included in this appendix are boring logs and well construction details for monitoring wells installed as part of this study. Drillina and Soil Sampling Monitoring wells were drilled with an 8 -inch diameter, continous-flight, hollow -stem augers. To avoid cross contamination, the augers were steam cleaned before drilling each monitoring well. Soil samples were obtained for soil classification and laboratory analysis. Samples were collected at 5 -foot intervals during the drilling of the wells or at significant lithology changes. Soil samples were retrieved ahead of the lead auger, utilizing an 18 -inch long by 2.5 -inch outside diameter, split -spoon sampler lined with brass sleeves. The sampler and brass sleeves were washed with a TSP or a commercial grade detergent solution and rinse with tap water before each sampling event. The sampler was driven by a 30 -inch free fall of a 140 -pound hammer. Blow counts were recorded on the logs of soil boring. Upon retrieval, the bottom of brass sleeve was immediately removed from the sampler, covered with aluminum foil, capped with plastic caps, tapped, labeled, and placed in a container with ice. A chain of custody was originated in the field for proper transportation and handling of the samples. The remaining soil samples recovered were extruded from the sampler and described in accordance with the Unified Soil Classification System (USCS). Monitoring wells Installation Monitoring wells were constructed of 2 -inch diameter and flush threaded, schedule 40, PVC blank and screened (0.020 -inch slot size) casings. The annular space surrounding the screened portion was backfilled with No. 3 Monterey sand (filter pack) to approximately 1 foot above the top of the screened section. A 1 -foot thick bentonite annular seal was placed above the filter pack and the remaining annulus was grouted with neat cement to the surface. Cristy boxes were installed slightly above the grade to minimize infiltration of surface runoff. Locking, water tight, caps were installed to insure the integrity of the well. APPENDIX C I• • • pi za 5p SAMPLING PROCEDURES All purging and sampling equipment was cleaned prior to each use to minimize cross -contamination between wells. All equipment in. contact with ground -water was triple rinsed prior to each sampling event in successive baths consisting of TSP of commercial grade detergent and tap water. Prior sampling, the wells were developed by a 2 -inch bailer. The wells were developed by purging at least 5 casing -volumes of water from each well. The purged water was stored onsite in 55 -gallon, DOT -approved, drums awaiting proper disposal. Ground water samples were collected by lowering a clean 2 -inch diameter bailer in each well after the well was properly purged. Well purging required the extraction of at least 3 casing volumes from each well. All purged water were stored onsite in 55 -gallon drums. Field parameters, such as pH, temperature, and conductivity, were observed. Water collected in the bailer was gently transferring into 40 -milliliter and 1 -liter glass containers. The glass containers complied with the LUFT manual in sample preservation techniques. All samples were inverted to ensure that entrapped air was not present. Water samples were then sealed, labelled, placed in a container with ice, and transported with a proper chain of custody to the laboratory.
