Written Statement The Alameda County Fire Department is excited to submit this application for a Conditional Use to have its Operations Complex located in the City of Dublin. The Alameda County Fire Department has proudly been serving the community since 1993 and providing services to Dublin since 1997. The building at 6400 Sierra Court proviiies the ACFD with an opportunity to combine all of the Fire Department's satellite support funci ions into one location. This will enable them to become more effective and efficient in pro~iiding superior service to their communities. The combination of office, industrial and warehouse uses in the area makes this location idea for a Fire Department Operations Complex. 1=ire Department Staff thank City Officials for considering this application and look forward to working with staff on this project. 2. Uses Initially it is planned that this facility will house the Fire Deirertments Headquarters, EMS Division, IT Division, Reserve Program, Training Division staff, and Apparatus Maintenance Division. The facility will also serve as the Departments Emergency Operations Center and will become the City of Dublin's Emergency Operations Center as well. The Fire Department also plans to move the Alameda County Regional Dispatch Center to this location at a future date. 2.1 Headquarters The Headquarters portion of the operations complex consists of mainly office and meeting room spaces for various Chief Officers and support staff members. Most of these offices will be located on the second floor of the facility. 2.2 EMS Division The EMS Division will have their offices located in the complex. They will also house equipment and supplies in the warehouse area of the building on the first floor. Additionally, they will be able to conduct training classes in the two large training rooms located on the first floor. 2.3 IT Division The IT Division will relocate the Fire Departments t:entral server room to this facility as well as all IT staff. IT offices will be located on the first floor of the facility. They will also utilize storage space on the first floor. 2.4 Reserve Program All Reserve Program equipment will be relocated to the Operations Center and it will be parked inside of the building on the first floor. ThE~ Reserves will also be able to hold meetings and/or trainings in the classrooms on the first floor. 3.1 Hours of Operation Headquarters and service center 8:00 am to 5:00 pm PAonday-Friday Reserves 6:00 pm to 10:00 pm Monday-Friday, 8:00-5:00 Weekends EOC's 24 hours as needed depending on the emergency AMD 8:OOam to S:OOpm Mon-Fri and as needed due to emergencies and workload Dispatch 24 hours :3 day 7 days a week 3.2 Number of Employees: Weekdays 50 Office and Shop Employee~c Evenings 70 Reserves for Meeting Weekends 30 Reserves for Classroom Tr<ining Dispatch 15 Dispatchers, Dispatch Managers, and Support Staff 3. Effects on Traffic The Traffic impacts for this use are minimal. During the week office employees are likely to make two trips or less each day in and out of the facility. Reserves coming to the facility for night meetings will need to make only one trip. Weekend activities would result in one trip each as well far half day meetings and two trips for all day meetings. Dispatch activities would also result in one trip per person per day. 4. On-Site Parking Per our agreement with the landlord will have a minimum of 102 parking spaces for our use.

This work was performed for Chevron USA Inc. (Chevron) and Robison Family Trust (Robison) in accordance with our May 14, 2008 Agreement (Agreement). Cornerstone Earth Group, Inc. (Cornerstone) understands that Robison has acquired the property from Chevron for continued commercial use. 1.1 BACKGROUND Robison acquired an approximately 13.4 acre property located at 6400 Sierra Court, Dublin, California (Site). The Site includes a 160,000 square foot warehouse previously owned and operated by Chevron with an additional 20,000 square foot office on the first floor. A Baseline Site Assessment Report conducted by URS (October 2007) revealed the following Recognized Environmental Conditions (RECs) at the Site: Four, 1,000-gallon above ground storage tanks (ASTs) located near the southeast corner of the Gettler-Ryan storage yard have been used to store purged ground water from Chevron retail stations that are undergoing remediation. Because the purged ground water is from stations undergoing remediation, it is likely to contain contaminants from these facilities. The ASTs did not have secondary containment, and the asphalt pavement beneath them contained significant cracks. • Tanks and drums of used granular activated carbon (GAC) were observed in the Gettler- Ryan lease area. The tanks and drums were not provided with secondary containment and were stored directly on asphalt pavements. Two drums containing used GAC were observed to have rusted along the bottoms. ^ Tank cradles for a former AST used by the previous occupant to store a material identified on Site plans as "Trico" were observed outside the west wall of the warehouse, adjacent to a gravel-filled storm water drain. • An area used for flammable chemical storage by the previous occupant was observed at the northwest corner of the building, adjacent to the gravel-filled storm water drain. 6400 Sierra Court, Dublin, CA Page 1 113-3-2 CORNERSTONE (..• EARTH GROUP Based on these observations, a subsurface investigation was conducted in these four areas to assess possible impacts to soil and ground water quality (URS, 2007). The analytical results revealed the following concerns: • Low concentrations of Total Petroleum Hydrocarbons as diesel (TPHd) were detected in shallow soil in the vicinity of the four 1,000-gallon purge water ASTs, but not in the deeper soil samples. • No fuel-related volatile organic compounds (VOCs) were detected in the soil samples from the GAC storage area and the only detection of TPH in the soil was TPHd at a concentration of 4.7 parts per million (ppm). • The only fuel or fuel-related VOCs detected in the ground water beneath the Gettler Ryan lease area were toluene (0.75 parts per billion [ppb]) and benzene (6.68 ppb). • No TPH or VOCs were detected in soil samples collected from the former Chemical Storage Building area; however, the halogenated solvent Trichloroethene (TCE) was detected above the Maximum Contaminant Level (MCL), commonly termed drinking water standard (5 parts per billion [ppb]), at 66 ppb. • Soil in the vicinity of the former "Trico" AST contained TCE up to 4,800 ppm and cis-1,2- Dichloroethene (cis-1 ,2-DCE) up to 31 ppm. The commercial Environmental Screening Levels (ESLs') are 0.46 ppm and 0.19 ppm, respectively. • Grab ground water samples collected near the former "Trico" AST contained concentrations of TCE and cis-1 ,2-DCE up to 66,000 ppb and 2,400 ppb, respectively. The MCLs for TCE and cis-1 ,2 DCE are 5 and 6 ppb, respectively. In March 2008, Cornerstone conducted a Preliminary Phase II Evaluation and reported the follow: • Soil sampled at a depth of approximately 11 feet inside the building at boring EB-4 (approximately 20 to 30 feet from the former "Trico AST") contained TCE at 0.77 ppm and cis-1 ,2 DCE at 3.1 ppm. These concentrations (0.46 and 0.19 ppm, respectively) exceeded the commercial ESLs. VOCs were not reported above laboratory detection limits in soil sampled from borings EB-5 (9 foot depth) and EB-6 (13'/~ foot depth). Nine ground water grab samples were collected to help evaluate the extent of TCE migration in the shallow water yielding zone. The highest reported ground water concentration during this investigation was reported inside the building closest to the former "Trico" AST (boring EB-4 at 707 ppb). Boring EB-5, advanced near the building's southern wall, exhibited a TCE concentration in ground water of 41.4 ppb. Borings (EB-10, EB-9, EB-8 and EB-7), advanced near the southern property boundary, exhibited TCE concentrations in ground water of 115 ppb, 89.4 ppb,98.5 ppb, and 24.1 ppb, respectively. The remaining borings either did not reveal TCE concentrations in ground water above the laboratory detection limit or exhibited less than 10 ppb. ' Environmental Screening Levels (ESLs) (May, 2008) were established by the California Regional Water Quality Control Board. ESLs are used to screen sites for potential human health concerns where releases of chemicals to soil have occurred. Under most circumstances, the presence of a chemical in soil below the corresponding ESL can be assumed not to pose a significant risk to human health. A chemical exceeding the ESL does not indicated that adverse impacts to human health are occurring or will occur but suggests that further evaluation of potential health concerns is warranted. 6400 Sierra Court, Dublin, CA Page 2 'Hot Spot' Removal 113-3-2 CORNERSTONE EAF~7H ~=.RC>iJP ^ Two surface water samples were collected from the Alamo Canal, The downstream sample contained TCE at 4.51 ppb. The upstream sample did not contain TCE at a concentration exceeding the laboratory detection limit. The downstream sample was collected approximately 400 feet of an upstream spillway. The surface water ESL1 is 5 ppb. ^ The soil vapor data were collected from four locations (three locations inside the warehouse and one near the suspect source area) ai depths of approximately 5 feet below ground surface and just beneath the stab in the underlying base rock inside the building (two distinct sampling depths). The soil vapor collected at a depth of approximately 5 feet contained Vinyl Chloride (up to 550,000 ug/m3 [CHHSL2 is 44.8 ug/m3]), trans-1 ,2 DCE (up to 84,000 ug/m3 [ESL is 41,000 ug/m3]), cis-1,2 DCE (up to 18,000 ug/m3 [ESL is 20,000 ug/m3]) and TCE (up to 1,100 ug/m3 [CHHSL is 1,770 ug/m3]). The vinyl chloride appears likely to be a breakdown product of TCE. The sub-slab soil vapor samples (samples collected from the baserock beneath the floor slab) contained, trans-1,2 DCE up to 1,000 ug/m3, cis-1 ,2 DCE up to 1,600 ug/m3 and TCE up to 7,000 ug/m3, Assuming an attenuation factor of 0.01 across the floor slab, TCE concentrations in sub-slab samples SV-1-SS and SV-3-SS and the cis-1,2 DCE concentration in SV-1-SS exceed their respective indoor air commercial ESL/CHHSL. ^ Although concentrations of TCE and cis-1 ,2 DCE were detected in the three indoor air samples analyzed, the reported concentrations did not exceed either the residential or commercial ESLs. 1.2 PURPOSE AND SCOPE OF WORK The purpose of this work was to remove the most highly contaminated soil ('hot spot') immediately beneath the former "Trico" AST to a depth above the capillary fringe of ground water (ground water anticipated to be approximately 18 to 22 feet below ground surface and under confined conditions). The lateral extent was limited to an area approximately 40 feet by 35 feet (approximately 2.0 by 35 feet inside the building and 20 by 35 feet outside of the building). It was intended by this work not to `chase' contamination as the extent of excavation activities was limited by the underpinning of the building's foundation. These interim measures were intended to help reduce the potential for indoor vapor intrusion and not to fully remediate the reported contamination in soil, soil vapor, ground water and surface water. The scope of work is described in the May 14, 2008 work plan (Appendix A). SECTION 2: "HOT SPOT" SOIL REMOVAL Activities presented in this section were performed in general accordance with the work plan dated May 14, 2008. The scope of the construction observation and testing services included a combination of part- and full-time observation and testing during the underpinning pier installation, the excavation activities and the backfilling of the excavation. Selected photographs are presented in Section 2.9. 6400 Sierra Court, Dublin, CA Page 3 'Hot Spot' Removal 113-3-2 CORNERSTONE L• EARTH GROUP 2.1 PRE-FIELD ACTIVITIES A grading permit application was prepared and submitted to the City of Dublin Public Works Department for performing this work; the permit was issued on June 23, 2008 (Permit N. 08-08, Appendix B). In addition, a building permit was obtained from the city of Dublin Building and Safety Division on July 15, 2008. The Bay Area Air Quality Management District (BAAQMD) also was notified as required by Regulation 8, Rule 40. Apre-demolition asbestos survey was required by the City of Dublin Building and Safety Division prior to issuing the building permit; the results of the asbestos survey are presented in Appendix B. Underground Service Alert (USA) was notified of the approximate excavation locations. A private utility locator was used to locate any underground utilities in the `hot spot' area. A gas line traversed the planned outside excavation area; PG&E inactivated the line prior to excavation activities. To document the condition of the foundation, wall, floor and access ramp in the area of the planned "hot spot" removal prior to performing the work, the structural engineer Biggs Cardosa performed apre-construction survey in June, 2008. The findings of the pre-construction survey are presented in Appendix B. A health and safety plan (HSP) was prepared by Brighton Environmental Consulting (Brighton). The purpose of the HSP was to provide guidance to work hazards that may be encountered during each phase of Site excavation activities. The HSP contained provisions for limiting and monitoring chemical exposure to construction workers, ventilation requirements for working inside the warehouse, chemical and non-chemical hazards, emergency procedures and standard safety protocols. Level C personnel protection was required for Site workers. Brighton's representative was present on-Site on a part-time basis to observe excavation activities. The HSP is presented in Appendix C. A California licensed structural engineer and a California licensed geotechnical engineer reviewed the available `as-built' plans to determine an appropriate foundation underpinning design. The general requirements (May 1, 2008 design) required the installation of five 30-inch diameter reinforced piers installed to a depth of approximately 27 feet below grade. 2.2 SITE PREPARATION Pacific States Environmental, Inc. (PSE), the remediation contractor, began Site preparation for underpinning and excavation activities on August 7, 2008. The asphaltic concrete pavement (AC) near the former "Trico" AST was saw-cut (approximately 35 feet by 20 feet); the AC and the AST saddles were removed. The interior floor of the warehouse (approximately 6-inches in thickness) also was saw-cut (approximately 35 feet by 20 feet) in an area near the AST and removed. Portable ventilation fans designed per the specification of Brighton were used to improve fresh air circulation, as needed. 2.3 UNDERPINNING On August 12, 2008, American Drilling mobilized a crew and equipment to the Site to underpin the foundation per the general requirements shown in the May 1, 2008 design. Underpinning 6400 Sierra Court, Dublin, CA Page 4 'Hot Spot' Removal 113-3-2 CORNERSTONE EARTH GROUP pier excavation began on August 15~h and was completed on August 19`h. The piers were constructed in general accordance with the approved plans; the conditions encountered were generally similar to those assumed for design. The five reinforced underpinning piers were constructed to 30 inches in diameter and to a minimum of 27 feet below the top of footing. Soil cuttings from the pier drilling were stockpiled at the south end of the Site on plastic sheeting. The stockpile was then covered with plastic sheeting. 2.4 SOIL EXCAVATION PSE began excavation activities on September 1 S`, 2008. The depth of the `hot spot' excavation was performed to meet the previously mentioned specifications and was limited to a depth of approximately 15 feet inside the warehouse (the maximum depth reasonable achievable using the limited access equipment used inside the building) and approximately 16 feet outside of the warehouse (the approximate depth that appeared to be near the top of the capillary fringe of the ground water table). The lateral extent of the excavation was limited to an area of approximately 40 feet by 35 feet (approximately 20 by 35 feet inside of the building and 20 by 35 feet outside of the building). The approximate removal area is shown on Figure 2. Soil encountered in the excavation generally consisted of silty clay to the total depth excavated. No ground water was observed ponding in the excavation. A natural gas pipeline, which had been disconnected by PG8~E, was exposed on the west sidewall of the excavation (Section 2.9, Photograph 3). The sand bedding beneath the pipe that was visible on the excavation sidewalls appeared moist. The sand bedding beneath the pipe was evaluated in the field using an OVM; no organic vapors were detected in the material. During excavation and underpinning, agravel-filled trench with an approximately 3-inch diameter slotted piping was encountered adjacent to the footing. The trench was approximately 1-foot deep and appeared designed to collect storm water runoff from roof down-spouts that terminated above the gravel-filled trench. During the excavation backfilling, the section of removed slotted piping was replaced with solid pipe (Section 2.9, Photograph 11). Thirteen verification soil samples (SV-1 to SV-13) were collected from the base and sidewalls of the excavation. The approximate verification sample locations are shown on Figure 3. Laboratory analyses of the verification soil samples are discussed in Section 3.1. 2.5 STOCKPILE PROFILING Excavated soil was separated into three stockpiles based on suspected contamination as measured using an Organic Vapor Meter (OVM) by our field geologist. Stockpile #1 was composed of "clean" soil (less than 20 ppm as measured with an OVM). Stockpile #2 was composed of moderately to highly contaminated soil (20 ppm or greater as measured with an OVM). Stockpile #3 was composed of soil removed from the approximate 15 to 16 foot depth of the exterior excavation. All stockpiled soil was stored on-Site on top of and covered by "impermeable" liner (6 mil). Gravel bags were placed around the stockpile to help secure the plastic sheeting. The stockpile locations are shown on Figure 2. On September 1, 16, and 23, 2008, a total of thirteen sample locations were collected from the three stockpile areas. Two sample locations were selected from stockpile #1 (SP-1 and SP-2); soil designated as `clean'. Ten sample locations were selected from stockpile #2 (SP-3 to SP- 12), soil designated as moderate to highly contaminated. One sample location was selected 6400 Sierra Court, Dublin, CA Page 5 'Hot Spot' Removal 113-3-2 CORNERSTONE `• EARTH GROUP from stockpile #3 (SP-13), soil excavated from the approximately 15 to 16 foot depth of the exterior excavation. Four composite soil samples (for example SP-10A, SP-10B, SP-10C, and SP-10D) were collected from each sample location; organic vapors were measured at each composite soil sample location using an OVM. A discrete sample was then collected from the location with the highest OVM reading of the four composite locations. Stockpile sample locations are shown on Figure 4. Laboratory analyses of the stockpile soil samples are discussed in Section 3.1. 2.6 VENTILATION PIPING SYSTEM On September 23rd, 2008, PSE began the installation of a ventilated piping system at the base of the excavation and beneath the floor slab. The ventilated piping system is shown in Figure 5. The ventilation piping was installed at the request of Chevron to be used for soil vapor/sub-floor vapor extraction. Three sections of 2-inch slotted pipe were installed at the base of the excavation (perpendicular to the building wall) in a bedding of approximately 3/<-inch open-graded, crushed rock that ranged in thickness from approximately 3/ foot on the interior base of the excavation to approximately 2- feet on the exterior base of the excavation. Non-woven filter fabric (Mirafi 140NC) was then placed directly over the crushed rock. Vertical solid PVC pipe risers were connected to each slotted pipe and extended to the surface. After backfilling the interior portion of the excavation (see Section 2.7); a second set of slotted pipes was placed approximately 2 feet below the interior floor slab elevation. Three sections of 2-inch slotted piping were placed in a bedding of approximately'/-inch open-graded, crushed rock. Approximately 3/.-foot of crushed rock was placed below the slotted piping. Crushed rock was then placed over the slotted pipe to the interior slab grade (approximately'/2 foot below interior floor). A visqueen vapor barrier was placed over the crushed rock. The slotted piping was connected to solid PVC pipe extending under the existing foundation to outside the building. The pipe was connected to a vertical riser that was placed on the north side (to the left of the bottom riser if facing the building from the outside) of the vertical PVC riser installed for the bottom set of slotted piping. 2.7 EXCAVATION BACKFILL On September 26, 2008, approximately 1 to 1 '/z feet of low moisture/high viscosity Controlled Density Fill (CDF) was placed directly over the filter fabric. The following workday, September 29, 2008, approximately 5 to 6 feet of CDF was placed (approximately 5'/z feet below existing grade). On September 30, 2008 plywood wood forms were placed against the outside of the concrete footing to help secure additional CDF fill on the interior side of the excavation. CDF was then placed to backfill the interior half of the excavation up to 2 feet below finished floor grade on September 30, 2008. Installation of the sub-floor vent piping/crushed rock is presented in Section 2.6. A visqueen vapor barrier was then placed over the crushed rock on October 6, 2008 and the concrete slab interior floor was poured on October 8, 2008 The remainder of the exterior excavation was backfilled with imported soil. A bulk soil sample of the backfill material was collected on October 7, 2008 for laboratory analysis. Upon approval by the Geotechnical Engineer, soil was imported to the Site on October 13 and 14, 2008. Imported backfill soil was compacted to approximately 90% relative compaction. Our field technician was 6400 Sierra Court, Dublin, CA Page 6 'Hot Spot' Removal 113-3-2 CORNERSTONE t.~.: F ARTH CRL~t..fP on-site to observe backfill and compaction on a part-time basis. Field density was tested using a nuclear density gauge. 2.8 HEALTH AND SAFET1~ Brighton performed part-time observation and monitoring for chemicals of concern (vinyl chloride, TCE and DCE) Initially, air monitoring consisted of colorimetric tube sampling at 15 minute intervals for vinyl chloride using colormetric tubes and continuous Photo Ionization Detector (PID) monitoring for VOCs, calibrated to isobutylene with a correction for vinyl chloride, TCE and DCE. Elevated odors and PID readings (greater than 40 ppm) were recorded at the pier and "hot spot" excavations . Level C personal protective equipment (1/2 face air purifying respirator) was required when working near these excavations when OVM readings and/or colormetric tubes exceeded the action levels presented in the HSP. Exhaust fans were used, as needed, to direct clean air into the worker breathing zone and VOC-impacted air out of the work area. Water was applied to soil during excavation and loading to reduce dust generation. The odors and organic vapor readings dissipated when saturated soil was encountered at an approximate depth of 20 feet in the pier excavations. Personal air monitoring was also conducted by Brighton on representative workers performing representative tasks, including pavement saw cut and removal, drilling, underpinning manual labor, exterior excavation, interior excavation and material transport. The samples were collected with a personal sampling pump with a representative sampler in line and sampled at 0.05 L/minute for 15 to 100 minutes. The samples were placed in an ice chilled cooler and transported to a laboratory certified in the performance of NIOSH 1007 analyses. Vinyl Chloride was not detected. Personal air monitoring data is presented in Table 2. Brighton's field notes and analytical results are presented in Appendix C. Table 1.

These samples were analyzed for VOCs by EPA Test Method 82606!5035. To evaluate soil quality of the stockpiled material for off-Site disposal, thirteen 4-point composite samples were collected in stainless steel liners. These samples were analyzed for 17 California Assessment Manual (CAM) metals (EPA Test Method 6000/7000), diesel ranged petroleum hydrocarbons (TPHd) and motor oil ranged petroleum hydrocarbons (TPHmo) (EPA Test Method 8015). A silica gel cleanup was performed for the TPHd and TPHmo analyses to remove naturally occurring organic compounds from the sample that can be detected, causing results to be artificially elevated. Each stockpile sample location was screened in the field for VOCs using an OVM, and additional soil samples (in triplicate) were collected using a Core N' One capsule from the location within each 4-point composite location with the highest VOC reading. These samples were analyzed for VOCs including BTEX and MTBE (EPA Test Method 8260/5035). Samples were delivered to astate-certified analytical laboratory under a chain of custody. Laboratory analyses of verification samples for VOCs are summarized in Table 2 and Figure 3. Laboratory analyses of stockpiled soil for VOCs are summarized in Table 3 and Figure 4; a summary of all compounds detected is presented in Tables 5 and 6 in the Appendix entitled "Tables".

The lateral extent was limited to an area approximately 40 feet by 35 feet (approximately 20 by 35 feet inside the building and 20 by 35 feel outside of the building). It was intended by this work not to `chase' contamination as the extent of excavation activities was limited by the underpinning of the building's foundation. Please Hate that these interim measures were intended to help reduce the potential for indoor vapor intrusion; they were not intended to remediate the reported contamination in soil vapor, ground water and surface water or the remaining contamination in soil. SECTION 5: LIMITA710NS Cornerstone performed this investigation to support Robison and Chevron in evaluation of soil quality beneath the Site. Robison and Chevron understand that the extent of soil data obtained is based on the reasonable limits of time and budgetary constraints. In addition, the chemical information presented in this report can change over time and is only valid at the time of this investigation and for the locations sampled. Observation", as used in this document, means that we observed the progress of the work on an intermittent basis, and performed tests on selected soil and rock materials. Our opinion about the general conformance of geotechnical aspects of construction to our recommendations and project plans and specifications is based on these observations and test results. Based on our field observations and test results, it is our opinion that the geotechnical aspects of the construction for the project that we observed and tested have been performed in general conformance with our recommendations and the approved project plans. This report, an instrument of professional service, was prepared for the sole use of Robison and Chevron and may not be reproduced or distributed without written authorization from Cornerstone. Cornerstone makes no warranty, expressed or implied, except that our services have been performed in accordance with the environmental principles generally accepted at this time and location. 6400 Sierra Court, Dublin, CA Page 16 'Hot Spot' Removal 113-3-2 ~G;Wd esioN uw~ Stl+.

THELEN LLP 225 West Santa Clara Street, Suite 1200 San Jose, California 95113 Re: Work Plan for `Hot Spot' Removal 6400 Sierra Court Dublin, California Dear Mr. Armstrong: Per your request, we submit this work plan for the `hot spot' removal in the area of the former "Trico" above ground storage tank (AST). Our work plan is based on the information provided to date, our discussions with you, representatives of the Robison Family Trust (Robison) and Chevron U.S.A. Inc. (Chevron), and our previous Site investigation. -• -• ~ We understand that Robison is proposing to acquire an approximately 13.4 acre property located at 6400 Sierra Court, Dublin, California (Site). The Site includes a 160,000 square foot warehouse owned and operated by Chevron with an additional 20,000 square foot office on the first floor. A portion of the property is leased by Alameda County Auction; it contains a small single-story building. An asphalt-covered portion of the property near the southern border is reportedly leased by Gettler-Ryan Incorporated (Gettler-Ryan) and used as an open storage area. Tank cradles for a former AST used by the previous occupant to store a material identified on Site plans as "Trico" were observed outside the west wall (rear) of the warehouse. Soil in the vicinity of the "Trico" AST contained Trichloroethene (TCE) up to 4,800 ppm and cis-1,2- Dichloroethene (cis-1,2-DCE) up to 31 ppm. The Environmental Screening Levels (CRWQCB, November 2007) are 0.46 ppm and 0.19 ppm, respectively. The purpose of this work plan is to remove contaminated soil ('hot spot') immediately beneath the former "Trico" AST; depth of soil excavation will be limited to approximately 15 feet (a depth reportedly just above the surface of ground water); and the lateral extent will be limited to an area 40 feet by 35 feet (20 by 35 feet inside the building and 20 by 35 feet outside of the 1253 ;.a.,kme~c,' P~~k~r,_=~~~ Surn~.-«~I~:+ C'~. 94oE5 ~ • hC7i~ 24~ G5(7C~ ~ F GF2c~ i ;S .6'i; r wti~~~a~ 4~,~ rt~r<tc~leeartY.~ n-~ ~ C CORNERSTONE E,A,RTH GROt.IP building. It is intended by this work plan not to `chase' contamination as the extent of excavation activities will be limited by the underpinning of the building's foundation. The proposal for `hot spot' excavation, dated May 14, 2008, is attached as Exhibit A to work plan. Our team for your project will be managed by Ron L. Helm, C.E.G., R.E.A. II and Kurt Soenen, P.E. Ron and Kurt will be supported by various technical and administrative staff as required. Pre-Field Activities As authorized, a California licensed structural engineer and a California licensed geotechnical engineer has reviewed the available `as-built' plans of the building to determine an appropriate underpinning design. Upon approval, we then will prepare a grading permit application to the City of Dublin for performing this work. Engineering review and permit submittal and approval will require approximately ten to fifteen working days. The Bay Area Air Quality Management District (BAAQMD) also will be notified as required by Regulation 8, Rule 40. We will contact Underground Service Alert (USA) to notify them of the approximate excavation locations. Please note that USA will not locate utilities on private property. Therefore, our fees include the use of a private utility locator to help locate utilities in the excavation area. Based on past Site work, a gas line runs through the planned outside excavation area. Chevron must notify PG&E to shut down this line; PG&E could take several weeks to perform this work. A health and safety plan (HSP) will be prepared by a Certified Industrial Hygienist (CIH). The purpose of the HSP is to provide guidance to work hazards that may be encountered during each phase of Site excavation activities. The HSP will contain provisions for limiting and monitoring chemical exposure to construction workers, ventilation requirements for working inside the warehouse, chemical and non-chemical hazards, emergency procedures and standard safety protocols. For budgetary purposes, Level C personnel protection will be required for Site workers. The CIH will be present on-Site to observe excavation activities on a part-time basis. The CIH will also assist in evaluating ventilation requirements if the contaminated soil from beneath the building floor slab is removed. Excavation Activities We will mobilize a crew and equipment to the Site to underpin the foundation per the general requirements shown in the May 1, 2008 design. Five 30-inch diameter reinforced piers will be installed to a depth of approximately 27 feet below grade. We then will saw-cut and remove the asphalt concrete (AC) pavement (35 feel by 20 feet) and the AST saddles. The interior floor of the warehouse (assumed to be 6-inches or less in thickness) also will be saw-cut (approximately 35 feet by 20 feet) in an area near the former "Trico" AST and removed. Ventilation fans designed per the specification of the CIH will be used to improve fresh air circulation. Excavation (approximately 600 cubic yards, including soil generated by Proposal No. 113-3-1 Page 2 May 14, 2008 'Hot Spot' Removal Sierra Court, Dublin, CA C CORNERSTONE EAF~Tt•d GROUP underpinning activities) will be performed by California licensed hazardous materials contractors and personnel trained in hazardous waste operations (40-hour HAZWOPER training). Our field geologist or engineer will direct the excavation and stockpiling of approximately 600 cubic yards of soil. The excavation sidewalls will be approximately vertical; the rear walls will have an approximate 1:1 slope with the lower 5 feel (approximately 10 to 15 feet depth) being vertical. The excavation will be limited to a depth of approximately 15 feet; attempting to stay above the first encounter of ground water. The lower half of the excavation will be backfilled with Controlled Density Fill (CDF), aself-compacting, Plowable material (150 psi concrete slurry mix) used as an economical backfill material - an alternative to granular fill The upper half of the exterior excavation will be backfilled with a clayey soil; the remainder of the interior excavation will be backfilled with CDF. After completion of excavation activities, the AC, warehouse floor and baserock (3 inches over 9 inches) will be replaced (approximately 1500 square feet) per the specifications of the geotechnical engineer. Segregation of Materials and Stockpiling Our field geologist or engineer will attempt to segregate and separately stockpile soil suspected to be moderately contaminated (20 to less than 40 ppm as measured with an Organic Vapor Meter [OVM]) and highly contaminated (40 ppm or greater as measured with an OVM) from "clean" soil (less than 20 ppm as measured with an OVM). Please note that the planned excavation method may limit our ability to efficiently segregate contaminated materials. Stockpiles will be stored on-Site on top of and covered by an "impermeable" liner (6 mil). Sand bags or similar material will be placed around the stockpile to attempt to secure the plastic sheeting, Analytical Testing The quality of soil stockpiled and left in place will be evaluated through analytical testing. Up to 30 soil samples will be analyzed for chlorinated volatile organic compounds (VOCs) (EPA Test Method 8260). Up to ten selected soil samples will be analyzed under the Toxicity Characteristic Leaching Procedure (TCLP) test method to classify the waste material for disposal options. Based on our past experience, TCE at concentrations greater than 50 parts per million may fail the TCLP and obtain the RCRA hazardous waste classification. The stockpiled material may require additional analytical testing for chemicals of concern as required by the disposal facility. For cost purposes, we have assumed up to twelve discrete samples (assuming, if possible, four samples collected from three stockpiles [suspected as clean, suspected as moderately contaminated and suspected as highly contaminated]) for VOCs including BTEX and MTBE (EPA Test Method 8260) and up to twelve 4-point composite samples for 17 CAM metals (EPA Test Method 6000/7000), TPHd and TPHmo (EPA Test Method 8015). A silica gel cleanup wilt be performed for the TPHd and TPHmo analyses to remove naturally occurring organic compounds from the sample that can be detected, causing results to be artificially elevated. Please note that the accepting facility may require additional analyses than those described above. In addition, we anticipate approximately 4,000 gallons of waste water being generated during the underpinning activities. This material will be contained in a 20,000 gallon FRAC tank. Two samples will be collected and analyzed for VOCs (EPA Test Method 8260). Proposal No. 113-3-1 Page 3 May 14, 2008 'Hot Spot' Removal Sierra Court, Dublin, CA C CORNERSTONE EAi;?Tt-! GPOUp' We will request a standard one-week laboratory response. Actual laboratory response will depend on the laboratory's availability. Waste Stockpiled impacted material will be loaded onto trucks provided by Chevron using arubber- tired loader. Daily street-sweeping, flag person and a manifesting technician also will be provided. Chevron will be responsible for the manifesting, transportation and disposal of this material. We assume drilling fluids are suitable for POTW disposal as non-hazardous waste at EBMUD Waste Water Treatment Plant in Oakland, California. Report We will prepare a report presenting the results of the interim remedial measures, the excavation of contaminated soil in the suspect source area. The report will include a Site map showing the sampling locations and copies of analytical reports and waste manifests. ~.~ ~~~ We anticipate approximately two to three weeks to obtain the grading permit from the City of Dublin, to prepare the HSP, and to complete the engineering specifications. Please note that Chevron, the current account holder, must notify PG&E to shut down the gas line located in the planned excavation area; PG&E could take several weeks or longer to perform this work. Field activities will take an additional four to five weeks. The stockpiled soil will be disposed upon the Chevron's selection of the disposal facility, obtaining an EPA Identification Number, signing waste manifests and determining waste characteristics and classification. The final report will be issued in approximately one to two weeks from the date of the receipt of the copies of the waste manifest.

The analytical results were compared to commercial environmental screening levels (ESLs) and California Human Health Screening levels (CNHSIs) established by the California Environmental Protection Agency (CalEPAj. Concentrations of vinyl chloride: trans-l,2-dirhloroethylene (trans- ?,2 DCE) and cis-1,2-Dichloraettrene{cis-1,2 DCE) exceeded their respective CHHSL and/or ESl from vapor samples coNected at 5 feet bgs. Concentrations of TCE exceeded the CHHSL andlor ESL from sub-slab soil uapor samples (samples collected from the baserock beneath the floor slab).. However, concentrations of TCE and cis-1,2 DCE reporked in indoor air samples did not exceed their residential or commercial CHHSL- andlor ESL. Therefore, ARCADIS does not recommend the collection of additional vapor data a# this time. Interim Corrective Action E3etween August 12 and October 14, 2008 CEG conducted an excavation in the area of the former Trico AST. The results of the excavation are presented within CEG's Hot Spot Removal Report, dated December 2, 2008. The excavation focused on removing soils from the "Hot Spot' area which was Hmited to an approximate depth of 15 feet bgs inside the warehouse and approximately 16 bgs feet outside the warehouse. Depth was limited to the approximated capil9ary fringe of the groundwater table. The lateral extent of the interior part of the excavation was approximately 20 feet by 35 feet and the exieriar was also 20 feet by 35 feet. Additional interim corrective action is not recommended at this time. Proposed Scope of Work The specific scope of work to address impacts to soil, groundwater, and surface water are discussed below. Slte Specific Health and Safety Plan As required by the Occupational Health and Safety Administration (OSHA) Standard "Hazardous Waste Operations and Emergency Response" guidelines {29 Code of Federal Regulations Section 1910.120), and by California Occupational Health and Safety Administration {Cal-OSHA) "Hazardous Waste Operations and Emergency Response guidelines (California Code of Regulations Title $, Section 5192), ARCADlS will prepare asite-specific environmental health and safety plan (E-HASP) prior to commencement of fieldwork. Field staff ar~d contractors will review the E- HASP before beginning field operations at the site. Bruce H.

Underground Utility Locating Underground Service Alert (USA1 will be notified a minimum of 48 hours prior to commencing field activities to identify any public utility alignments that may be in conflict with the proposed borings. In addition, a private utility locating company will be utilized for clearing proposed borings locations for underground utilities. Soil and Groundwater ARCADIS will advance twelve borings in six locations as illustrated on Figure 2 using sonic drii}ing technology. The initial six borings will be advanced to a depth based on field conditions to develop an understanding of the stratigraphy in the area of the site. The remaining six borings w11 be advanced to collect depth-discrete groundwater samples from the previously identified higher permeability zones. Fallowing the completion of sampling the second boring will be converted into a first encountered groundwater monitoring weN. Initial groundwater in this area is anticipated at approximately 18 feet bgs based on information obtained from the previous investigation at #his site conducted by CEG and from sites identified in the State of California Geotracker database in proximity to this site. Soil The locations wilt be hand cleared using either an air knife or hand auger to a minimum depth of 8 feet 1 inch {utility clearance depth} bgs or as conditions permit. Soil samples for logging purposes will be collected continuously for visual classification from 8 feet 1 inch bgs to the total borehole depth. The boreholes wi{1 be advanced avith 4 inch diameter inner core tube in 2.5 foot sections of 20 foot runs. Each discrete interval will be logged for soil characteristics including soil type, color, moisture content, etc. In addition, visual observations wilt be noted regarding observed odor, staining, and relative volatile organic compound concentrations as measured with aphoto-tornzation detector {t'iD) from soli head space. Following the inner core run, a 6.375 inch outer diameter (OD) temporary outer drive casing wiH be advanced to the depth of the inner core run. After each core run, the resultant soil core will be extruded into a specially designed clear plastic core bag to ensure that E3ruce H. iNol#e April 29, 200W Page: ~'•~:a0=1i:'*CMUa'1~e~~aa~tM!+o CAdC-dMCltE4FrJMti!.niunAEmma+ CMnnri kxant~ r nilhl5 i.'~.wr~.mG6!st43'mi F~~r1~AdAM ~ ~NcA7i.w,3)i 91iNhp d',c 4~~ ARCADIS no core sample will be lost.

Sol!-Water Snake 7esi Additionally, based on elevated P1D readings, soil samples will be screened for dense non aqueous phase liquids (DNAPL) utilizing asoil-wafer shake test. A small quantity of soil (up to 15 cubic centimeters [ccj) will be placed in a clear, colorless, 40 mifiiliter (mL) VOA containing an equal volume of potable or distilled water. After the soil settles in to the water the surface of the water will be evaluated for a visible sheen. The jar will be clased and gently shaken for approximately 10 to 20 seconds. Again, the surface of the water will be evaluated for a visible sheen or a temporary Layer of foam. A small quantity (approximately 0.8 to 1 cc) of Oil Red O or Sudan IV powder will be placed in the jar. The sheen layer will be evaluated for a reaction to the dye (change to bright red color). The jar will be closed and gently shaken for approximately 10 to 20 seconds. The contents in the closed jar will be examined for visible bright red dyed liquid inside the jar. A positive test result will be indicated by the presence of a visible sheen and foam on the surface of the water, a reaction between the dye and the sheen layer upon first addition of the dye powder, a bright red coating on the inside of the vial (particularly above the water tine), or red-dyed droplets within the soil !f DNAPL is identified the boring will not be further advanced to minimize the potential to mobilize the DNAPL deeper into the underlying soil units.

Monitoring Well Instai3atian The six soil borings will be converted into first encountered groundwater monitoring wells upon the completion of drilling. The borings will be tremie grouted to approximately 30 feet bgs. Two fee# of #2112 sand will be placed above the grout. The monitoring wells will be constructed using 2 inch OD schedule 40 poly vinyl chloride (PVC) casing with a 10 feet screen interval of 0.010-inch slotted PVC at the base of the we11 (13 to 23 feet bgs). A #2112 sand filter pack will be placed around the well from the bottom of the bore hole to approximately 2 feet above the screen interval {13 to 11 feet bgs) followed by 2 feet of coated bentonite chips (9 to 11 feet bgs) which will be allowed to hydrate for approximately 30 minutes prior to the addition of the grout seal. The remainder of the space will be filled with grout using a tremie pipe (1 to 9 feet bgs). The well will be finished off with a traffic rated well vault set in concrete (0 to 1 feet bgs).

(~ iNE CHICAGO TITLE SYMBOL Our corporate symbol is inspired by ths~t age-old aphorism, "A man's home is his castle." For just as meciieval castles survive to this day, the men and women of Chicago Title Insurance Company deliver the kind of protection that ensures oizr clients' real estate in- vestments will endure for many years to come. The castle conveys what we stand for: "Strength". The turret motif of our logo is modeled after the old Chicago Water Tower, one of the few edifices to survive the Great Chicago Fire. But the ring around the castle is of even greater significance - it is emblematic of a moat. As a moat protects a castle's walls, so our title insurance protects our customers' properties. As you know, the deeper and wider the moat, the more it s:cfeguards the castle. And at Chicago Title Insurance Company, we boast unsur- passed resources as the #1 title insurance company in America, spanning the country with more than 4,000 locations nationwide. Since 1847, we've been standing behind American property owners, ready to defend them swiftly and :firmly, summoning our strength from reservoirs hard won by lon€;, consistent prudence. 0 ®CHICACiO TITLE COMPANY ®CTIC 1993 ASSESSOR'S MAP 941 Cade n«4 No>;.2s-oor Scale ~ I'~ •400' 2 ~`~ MAP OFA SUB.OF PLOT A OF THE DOUGHERTY RANCNcBkisPa.i7) P.
