(Sierra) is pleased to present this proposal for preliminary subsurface assessments at the subject location hereafter refer to as Site. The assessment was requested by Santa Clara Valley Water District (SCVWD) in a letter dated July 16, 1998, as result of unauthorized fuel leak which have impacted soil beneath the former underground storage tank and piping at the Site in 1987. In its letter, SCVWD requested that City of Campbell investigate the vertical and horizontal extent of soil contamination and determine whether groundwater has been impacted with petroleum hydrocarbons beneath the Site. This proposal describes the scope of the requested preliminary subsurface assessment work in detail. BACKGROUND According to a letter prepared by SCVWD dated February 10, 1992, a 300-gallon fuel underground storage tank (UST) was discovered under the sidewalk near the Site during sewer pipeline installation in 1987. A report prepared by Geonomics, Inc. Dated October 12, 1987, indicated that 8,800 parts per million (ppm) total petroleum hydrocarbons as gasoline (TPHG) and 490 ppm total petroleum hydrocarbons as diesel (TPHD) were detected in a soil sample collected adjacent to the UST pit at an approximate depth of 15 feet below ground surface (bgs). It appears that the tank has not been removed yet. OBJECTIVE The objective of the work is to assess the horizontal and vertical extent of soil contamination, and determine whether petroleum hydrocarbon fuel has impacted the groundwater beneath the Site. SCOPE OF WORK Sierra will drill three soil borings at the Site, and convert one of the borings to a groundwater monitoring well. Because the UST is located beneath the sidewalk, underground utilities may exist near the tank pit, therefore, Sierra will not drill any borings on the street at this time. The actual boring locations will be determined after all underground utilities will be marked. Sierra will collect soil and groundwater samples for chemical analysis, as well as groundwater data from the monitoring well. After obtaining the analytical results and the groundwater data, Sierra will prepare a report summarizing the findings, and it will include recommendations. Sierra will perform its services in accordance with the following tasks: Task 1 - PREFIELD ACTIVITIES Before starting the field activities, Sierra will review the Site's historical information, mark boring locations, coordinate with a state-licensed drilling contractor, a state-certified analytical laboratory, and the client. Sierra will also retain a concrete diamond coring company to core concrete in the drilling areas (if necessary). Sierra will prepare a health and safety plan for its employees and sub-contractors. Sierra will obtain appropriate drilling and well construction permit from SCVWD, and notify Underground Services Alert (USA) to clear all the utilities. Sierra will prepare necessary equipment and material before starting the drilling activities. Sierra will coordinate with the City to obtain encroachment permit for drilling on the sidewalk. Sierra will contact SCVWD prior to starting the work, and notify them of the starting date. Task 1 - FIELD ACTIVITIES Drilling and Sampling Activities Based on our experience drilling exploratory borings in the City of Campbell, the underlying material may consist of sandy gravel and cobble, and groundwater level may ranges between 35 to 70 feet below ground surface (bgs). If such conditions exist at the Site,.due to permeability of soil type in the general area, fuel release had more tendency to travel vertically rather than horizontally, therefore, Sierra will drill 4. borehole near the perimeters of the former tank excavation at the Site, and convert one of them (downgradient of the former tank excavation) to a groundwater monitoring well. Three of the boreholes will be drilled to 30 feet bgs to examine whether horizontal migration of fuel has impacted the soil at these areas. The fourth borehole will be drilled to reach groundwater at an approximate depth of 50 feet bgs. Clean continues fly hollow stem augers will be used for the drilling. Soil samples will be collected at 5-foot intervals, starting at 5 feet bgs (anticipated bottom of the UST). The samples will be screened with photoionization detector (PID) for petroleum hydrocarbons. Soil samples will be collected using a California standard split spoon sampler lined with clean 6-inch long clean brass rings. After collection, the samples will be screened with PID, sealed with Teflon® tape and plastic end caps, and placed in a cooler pending the groundwater sample collection. After collecting the soil samples, the borings will be sealed with neat cement. Sierra will place the drill cuttings on plastic sheet at a designated location at the Site pending analytical results for the soil samples. All drilling and sampling equipment will be washed with Liquinox° (a phosphate-free laboratory detergent) and rinsed with clean tab water at each sampling interval. Groundwater Monitoring Well Construction Sierra will convert one of the borings into a groundwater monitoring well at the Site. The depth of the well will be determined in the field. 2-inch diameter slotted and solid casing will be used in the construction of the well. The well will be constructed in accordance with the "Standards for the Construction and Destruction of Wells and Other Deep Excavations in Santa Clara County", Revised June 1989. Before the drilling activities starts, Sierra will notify SCVWD representatives to observe the completion of the well construction. After construction, Sierra will develop the well and collect one groundwater sample for chemical analysis. The well will be developed in accordance with the SCVWD requirements. The extracted water from the well will be stored in 55-gallon drums located at a designated area at the Site. Before sample collection, groundwater data will be recorded. Sierra will collect a groundwater sample using a clean bailer. After collection, the groundwater will be transferred into appropriate clean containers supplied by the laboratory. The containers will be sealed, labeled, and placed in a cooler to be delivered to the laboratory with the chain-of-custody documentation. Task 3 - CHEMICAL ANALYSIS Soil and groundwater samples will be analyzed for total petroleum hydrocarbons as gasoline and diesel (TPHG and TPHD, respectively) using United State Environmental Protection Agency (EPA) modified method 8015, and for benzene, toluene, ethylbenzene, and xylenes (BTEX), and Methyl Tertiary Butyl Ether (MTBE) using EPA method 8020. Task 4 - REPORT PREPARATION AND SUBMITTAL Sierra will prepare a report for documenting the field observations, soil boring logs, well construction diagram, the analytical results, and recommendations. Three copies of the report will be submitted to the client. COST ESTIMATE Sierra's cost for the work outlined in the above tasks is $13,508. Table I presents the detail cost for each task. The cost estimate is based on the assumption that groundwater level will be approximately 50-60 feet bgs, and the total depth of the well does not extent 70 feet-bgs. The cost does not include waste water or contaminated drill cuttings (if any) disposal. SCHEDULE Sierra is prepared to start this project as soon as your authorization to start is received through a purchase or work order. We anticipate to complete this project within three weeks after receiving your authorization to proceed. We appreciate the opportunity of submitting this proposal, and look forward to serving you on this project. Please feel free to call me if you have questions.

As we discussed, the above unauthorized fuel leak releases reported to the Santa Clara Valley Water District, the lead agency for oversight of investigation and cleanup of petroleum hydrocarbon releases in Santa Clara County, are in undeterminate status. The extent of residual soil contamination and the impact to groundwater is unknown at all three sites. The maximum contaminant concentrations reported for Total Petroleum Hydrocarbons as Gasoline (TPHG), Total Petroleum Hydrocarbons as Diesel (TPHD), and Benzene in soil samples retrieved below tank excavations are listed in the table below. We are concerned that residual soil contamination-may be degrading the groundwater resource. Investigate the vertical and horizontal extent of soil contamination and determine if groundwater has been contaminated beneath each site. if groundwater has been affected, groundwater monitoring well(s) will be required. We request that you retrieve soil samples to be analyzed for TPHG, TPHD, Benzene, Toluene, Ethylbenzene, and Xylene, in addition to analyses for Methyl tert-Butyl Ether at discreet depths below the tank excavation surface depth. This data will help advance theses cases toward closure.

Cf^' Subject: Fuel Leak at Sunnyside and Winchester The Regional Water Quality Control Board (RWQCB) records indicate that a subsurface release of petroleum hydrocarbons at the above site has impacted, or threatens to impact, waters of the State. The RWQCB is the State agency responsible for enforcing the California Water Code for protection of beneficial uses of both surface and groundwater. Pursuant to the Water Code, polluted soil and groundwater must be remediated to the satisfaction of the Board The RWQCB has been unable to provide complete oversight of all reported cases of subsurface leaks involving fuels because of the large number of cases being reported However, a new pilot program has been developed between the RWQCB and the Santa Clara Valley Water District (SCVWD) in which SCVWD staff will provide the technical oversight on these cases. The investigation and cleanup of a petroleum leak usually involves the following steps: Definition of the extent of soil and groundwater pollution Hydrogeologieal evaluation of subsurface conditions Development of remedial action plans for polluted soils, dissolved petroleum constituents in groundwater, and free floating product Implementation of appropriate remedial actions Monitoring to ensure that remedial actions are effective Final case review and sign off As the investigation and cleanup proceeds, it is requested that copies of all future reports, letters, etc., should be submitted to the SCVWD, the RWQCB, and the local implementing agency.
