EXECUTIVE SUMMARY

8575.000.001 December 3, 2009

ENGEO Incorporated (ENGEO) conducted a phase one environmental site assessment for the property (Property), located at the northeast comer of Stone Valley Road and Miranda Avenue in Alamo, California (Figure I). The Propetiy, measuring approximately 1.25 acres in area, is identified with Assessor's Parcel Number (APN) 193-130-025 (Figure 2). The current Property use consists of a residential dwelling and related facilities at the northwestern portion of the Property. The southeastern portion of the Property is vacant. Stone Valley Creek is located along the northern edge of the property and is heavily vegetated and incised. The creek bank is approximately 10 to 12 feet high.

The study included a review of local, state, and federal environmental record sources, standard historical sources, aerial photographs, fire insurance maps and physical setting sources, and a reconnaissance ofthe Property to review site use and current conditions to check for the storage, use, production or disposal of hazardous or potentially hazardous materials.

The site reconnaissance and records review did not find documentation or physical evidence of soil or groundwater impairments associated with the use of the Property. A review of regulatory databases maintained by county, state, and federal agencies found no documentation of hazardous materials violations or discharge on the Property. A review of regulatory agency records and available databases did not identify contaminated facilities within the appropriate ASTM search distances that would be expected to impact the Property.

Based on a review of historical record sources, a portion of the Property was historically cultivated as an orchard. To determine if remnant concentrations of agricultural chemicals remain, a limited soil sampling program was performed. Although an analysis of the soil samples identified trace concentrations of two organochlorine pesticides, these concentrations were well below respective regulatory screening levels.

Based on the findings of this assessment, no Recognized Environmental Conditions (RECs) were identified for the Property .

ENGEO has performed a phase one environmental site assessment of the Property in general conformance with the scope and limitations of ASTM E 1527-05 "Standard Practice for Environmental Site Assessments" and USEPA "Standards and Practices for All Appropriate Inquires", 40 CFR Part 312. Based on the findings of this assessment, ENGEO recommends that an environmental professional observe grading operations for evidence of former septic systems at the Property. FtUiher, although no subsurface impact was noted following the removal of an underground storage tank in 1993, an environmental professional should observe grading operations near the former location of the tank for evidence of impact. Finally, if the current on-site structures are to be demolished, an environmental professional should be retained to determine if asbestos-containing building materials and/or lead-based paint are present.

1.0 INTRODUCTION

8575.000.001 December 3, 2009

ENGEO Incorporated (ENGEO) conducted a phase one environmental site assessment for the property (Property), at the northeast corner of Stone Valley Road and Miranda Avenue in Alamo, California (Figure I). The Property, measuring approximately 1.25 acres in area, has a physical address of2100 Stone Valley Road and is identified with Assessor's Parcel Number (APN) 193-130-025 (Figure 2). The current Property use consists of a residential dwelling and related facilities at the northwestern portion of the Property. The southeastern portion ofthe Property is vacant. Stone Valley Creek is located along the northern edge of the property and is heavily vegetated and incised. The creek bank is approximately 10 to 12 feet high.

1.1 PURPOSE OF PHASE ONE ENVIRONMENTAL SITE ASSESSMENT

This assessment was performed at the request of the San Ramon Valley Fire Protection District for the purpose of environmental due diligence during Property acquisition. The objective of this phase one environmental site assessment is to identify Recognized Environmental Conditions (RECs) associated with the Property. As defined in the ASTM Standard Practice E 1527-05, a REC is "the presence or likely presence of any hazardous substances or petroleum products on a property under conditions that indicate an existing release, a past release, or a material threat of a release of aoy hazardous substances or petroleum products into structures on the property or into the ground, groundwater, or surface water ofthe property".

1.2 DETAILED SCOPE OF SERVICES

The scope of services performed included the following:

• A review of publicly available and practically reviewable standard local, state, tribal, and federal environmental record sources.

• A review of publicly available and practically reviewable standard historical sources, aerial photographs, fire insurance maps and physical setting sources.

• A reconnaissaoce of the Property to review site use and current conditions. The reconnaissaoce was conducted to check for the storage, use, production or disposal of hazardous or potentially hazardous materials.

• Interviews with public sector officials.

• Preparation of this report with our findings, opinions, and conclusions.

1.3 LIMITATIONS AND EXCEPTIONS OF ASSESSMENT

Stained SoilfPavement. No stained soil or pavement was observed within the Property at the time of our reconnaissance.

Stressed Vegetation. No signs of stressed vegetation were observed on the Propelty at the time of our reconnaissance.

Solid WastelDebris. No evidence of solid waste disposal at the Property was observed during the reconnaissance.

Wastewater. No wastewater conveyance systems were observed at the Property during the reconnaissance.

Wells. Remnant well equipment was observed approximately 30 feet from the garage structure. According to reviewed documents, the well extended to a depth of 100 feet below the ground surface. The eight-inch-diameter well casing was embedded in a slab of concrete. The well was destroyed in October 2009.

Septic Systems. No evidence of septic systems was observed within the Property during our reconnaissance. According to a review of documentation regarding utility service, the Property is served by a municipal water and sanitary sewer utility. However, given the age and history of residential use at the Property, remnant septic system equipment may be present at the Property.

4.4 INTERIOR OBSERVATIONS

The interior of the structures present within the Property were not observed during the reconnaissance.

4.5 ASBESTOS-CONTAINING MATERIALS AND LEAD-BASED PAINT

An asbestos and lead-based paint survey was not conducted as part of this assessment. Given the age of the structures, it is possible that asbestos-containing materials or lead-based paint materials are present within the structures. If these structures are to be demolished, and environmental professional should be retained to determine if asbestos-containing materials and/or lead-based paint are present.

4.6 INDOOR AIR QUALITY

An evaluation of indoor air quality, mold, or radon was not included as part of the contracted scope of services. The California Department of Health Services has conducted studies of radon risks throughout the state, sorted by zip code. Results of the studies indicate that five tests were conducted within the Property zip code, with none of the tests exceeding the current EPA action level of 4 picocuries per liter [pCilL]l).

5.0 INTERVIEWS

8575.000.001 December 3, 2009

Mr. Steve Hart, Assistant Fire Chief of the San Ramon Valley Fire Protection District, completed questionnaires as both a User of this report and as Key Site Manager of the Property. Mr. Hart acknowledged the former presence and subsequent removal/destruction of the underground storage tank and the domestic water well the Property. Mr. Hart was unaware of any environmental impacts associated with the Property. The questionnaires are presented in Appendix G.

6.0 LIMITED SOIL SAMPLING PROGRAM

Because of the potential presence of renmant agricultural chemicals at the Property, limited soil sampling was performed on November 17, 2009. A total of four soil samples were collected from surface soils in locations depicted on Figure 4. Samples were recovered in pre-cleaned 2-inch-diameter, 6-inch-Iong stainless steel sample tubes. Equipment was decontaminated in an Alconoxlwater wash solution and triple rinsed with distilled water between borings. Upon recovery, all samples were sealed with Teflon, end caps and tape. The sealed samples were labeled and placed in an ice-cooled chest until delivery under documented chain-of-custody to TestAmerica Laboratories, Inc., a State certified laboratory located in Pleasanton, California. Samples were tested for the following target analytes:

• Total arsenic content using EPA Method 601 OB • Organochlorine pesticides using EPA Method 8081A

The laboratory analysis report is presented in Appendix H. The laboratory analysis of the soil samples did not identifY detectable concentrations of arsenic. Two pesticide analytes were detected. Dieldrin was detected with a concentration of 6.9 micrograms per kilogram (j.tglkg), and 4,-4' DDE was detected with a concentration of 2.7 j.tglkg. Both of these concentrations are below respective regulatory screening levels. Based on the analysis, the potential of environmental impact to surface soils due to previous agricultural activity is considered low, and it is our opinion that the presence of trace analyte concentrations does not affect the proposed redevelopment of the Property as a fire station. ENGEO does not recommend additional soil sampling at this time.

7.0 FINDINGS

The reconnaissance and records research did not find documentation or physical evidence of soil or groundwater impairments associated with the current or past use of the Property. A review of regulatory databases maintained by county, state and federal agencies found no documentation of hazardous materials violations or discharge on the Property. No documented soil or groundwater contamination associated with abutting properties was found from the records research.

A fonner underground storage tank was removed from the Property in 1993. No evidence of a tank release was observed at the time of removal, and site closure was suggested by the oversight agency. Although there does not appear to be evidence of impact from the fonner tank, an environmental professional should observe proposed grading activity in the vicinity of the fonner tank to determine if evidence of environmental impact is present.

Based on a review of historical record sources, a portion of the Property was historically cultivated as an orchard. To determine if remnant concentrations of agricultural chemicals remain, a limited soil sampling program was performed. Although an analysis of the soil samples identified trace concentrations of two organochlorine pesticides, these concentrations were below respective regulatory screening levels.

Based on the findings of this assessment, no RECs were identified for the Property.

8.0 OPINIONS AND DATA GAPS

It is our opinion that the findings of this study are based on a sufficient level of infomlation obtained during our contracted scope of services to render a conclusion as to whether additional appropriate investigation is required to identify the presence or likely presence of a REC.

The data gaps identified during this process, if any, do not affect the conclusions as to the presence or lack of presence ofRECs at the Property. The following data gaps were identified:

• The interiors of the structures at the Property were not entered.

The data gaps identified during this process do not affect the conclusions as to the presence or lack of presence ofRECs at the Property.

9.0 CONCLUSIONS

The study included a review of local, state and federal environmental record sources, standard historical sources, aerial photographs, fire insurance maps and physical setting sources, a reconnaissance of the Property to review site use and current conditions to check for the storage, use, production or disposal of hazardous or potentially hazardous materials and interviews with persons knowledgeable about current and past site use.

The site reconnaissance and records review did not find documentation or physical evidence of soil or groundwater impairments associated with the use of the Property. A review of regulatory databases maintained by county, state, and federal agencies found no documentation of hazardous materials violations or discharge on the Property. A review of regulatory agency records and available databases did not identify contaminated facilities within the appropriate ASTM search distances that would be expected to impact the Property. Based on a review of historical record sources, a portion of the Property was historically cultivated as an orchard. To determine if remnant concentrations of agricultural chemicals remain, a limited soil sampling program was perfonned. Although an analysis of the soil samples identified trace concentrations of two organochlorine pesticides, these concentrations were below respective regulatory screening levels.

Based on the findings of this assessment, no RECs were identified for the Property.

ENGEO has performed a phase one enviromnental site assessment of the Property in general conformance with the scope and limitations of ASTM E 1527-05 "Standard Practice for Environmental Site Assessments" and USEPA "Standards and Practices for All Appropriate Inquires", 40 CFR Part 312. Based on the findings of this assessment, ENGEO recommends that an enviromnental professional observe grading operations for evidence of former septic systems at the Property. Further, although no subsurface impact was noted following the removal of an underground storage tank in 1993, an enviromnental professional should observe grading operations near the former location of the tank for evidence of impact. Finally, if the current onsite structures are to be demolished, an environmental professional should be retained to determine if asbestos-containing building materials and/or lead-based paint are present.

These plants used whale oil, rOSin. coal. or a mixture of coal, all, and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds are potentially hazardous to human health and the environment. The byproduct from this process was frequently disposed of direclly at the plant site and can remain or spread slowly, serving as a continuous source of soil and groundwater contamination.

EDR's GeoCheck Physical Setting Source Addendum is provided to assist the environmental professional In forming an opinion about the impact of potential contaminant migration.

Assessment of the impact of contaminant migration generally has two principle investigative components:

1. Groundwater flow direction, and 2. Groundwater flow vetocity.

Groundwater flow direction may be Impacted by surface topography, hydrology, hydrogeology, characteristics of the soil, and nearby wells. Groundwater flow velocity is generally impacted by the nature of the geologic strata.

TC02607290.2r Page A-1

GEOCHEC~. PHYSICAL SETTING SOURCES.UMMARY ..

GROUNDWATER FLOW DIRECTION INFORMATION

Groundwater flow direction for a particular site is best determined by a qualified environmental professional using site-specific well data. If such data is not reasonably ascertainable, it may be necessary to rely on other sources of Information, such as surface topographic information, hydrologic information, hydrogeologic data collected on nearby properties, and regional groundwater flow Information (from deep aquifers).

TOPOGRAPHIC INFORMATION

Surface topography may be indicative of the direction of surficial groundwater flow. This information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property, what downgradient sites might be impacted. .

HYDROGEOLOGIC INFORMATION

Hydrogeologic information obtained by inslallation of wells on a specific sile can often be an indicator of groundwater now direction in Ihe immediate area. Such hydrogeologic information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property, what downgradlent sites might be impacted.

GROUNDWATER FLOW VELOCITY INFORMATION

Groundwater flow velocity information for a particular site is best determined by a qualified environmental professional using site specific geologic and soil slrata data. If such data are not reasonably ascertainable, it may be necessary to rely on other sources of information, including geologic age identification, rock stratigraphic unit and soil characteristics dala collected on nearby properties and regional soli information. In general, contaminant plumes move more quickly through sandy-gravelly types of soils than silty-clayey types of soils.

GEOLOGIC INFORMATION IN GENERAL AREA OF TARGET PROPERTY Geologic information can be used by the environmental professional in forming an opinion about the relative speed at which contaminant migration may be occurring.

2009 Enhancefllents to EDR City Directory Abstract

New for 2009, the EDR City Directory Abstract has been enhanced with additional information and features. These enhancements will make your city directory research process more efficient, flexible, and insightful than ever before. The enhancements will improve the options for selecting adjoining properties, and will speed up your review of the report.

City Directory Report. Three important enhancements have been made to the EDR City Directory Abstract:

1. E)(ecutive Summary. The report begins with an Executive Summary that lists the sources consulted in the preparation of the report. Where available, a parcel map is also provided within the report, showing the locations of properties researched.

2. Page Images. Where available, the actual page source images will be included in the Appendix, so that you can review them for information that may provide additional insight. EDRhas copyright permission to include these images.

3. Findings Listed by Location. Another useful enhancement is that findings are now grouped by address. This will significantly reduce the time you need to review your abstracts. Findings are provided under each property address, listed in reverse chronological order and referencing the source for each entry.

Options for Selecting Adjoining Properties. Ensuring that the right adjoining property addresses are searched is one of the biggest challenges that environmental professionals face when conducting city directory historical research. EDR's new enhancements make it easier for you to meet this challenge. Now, when you place an order for the EDR City Directory Abstract, you have the following choices for determining which addresses should be researched.

1. You Select Addresses and EDR Selects Addresses. Use the "Add Another Address" feature to specify the addresses you want researched. Your selections will be supplemented by addresses selected by EDR researchers using our established research methods. Where available, a digital map will be shown, indicating property lines overlaid on a color aerial photo and their corresponding addresses. Simply use the address list below the map to check off which properties shown on the map you want to include. You may also select other addresses using the "Add Another Address" feature at the bottom of the list.

2. EDR Selects Addresses. Choose this method if you want EDR's researchers to select the addresses to be researched for you, using our established research methods.

3. You Select Addresses. Use this method for research based solely on the addresses you select or enter into the system.

4. Hold Qity Directory Research Option. If you choose to select your own adjoining addresses, you may pause production of your EDR City Directory Abstract report until you have had a chance to look at your other EDR reports and sources. Sources for property addresses include: your Certified Sanborn Map Report may show you the location of property addresses; the new EDR Property Tax Map Report may show the location of property addresses; and your field research can supplement these sources with additional address information. To use this capability, simply click "Hold City Directory research" box under "Other Options" at the bottom of the page. Once you have determined what addresses you want researched, go to your EDR Order Status page, select the EDR City Directory Abstract, and enter the addresses and submit for production.

Since joining ENGEO in 1985,"Mr. Munger has been managing groundwater supply evaluations, hydrogeologic studies, chemical assessments, phase one and two site assessment projects, UST site investigations, lisk based corrective action (RBCA), VOC remediation, and agticultural impact evaluations. He serves as Principal-in-Charge or Project Manager for environmental and hazardous materials projects involving groundwater hydrology, contaminant fate and transpOlt, and remediation.

620 North 9th Street, San Jose, CA Mr. Munger is Principal-in-Charge for groundwater and soil gas characterization study for former Del Monte Packing Plant site in San Jose. His scope of services included meetings and interaction with multiple members of the San Francisco Regional Water Quality Control Board, and preparation of a Remedial Management Plan and public participation notifications.

ENGEO perfOlmed a Phase One Environmental Site Assessment and a subsequent Phase Two Environmental Site Assessment for the 3.1-acre proposed residential property. The property is currently occupied by two commercial warehouses and surrounding asphalt parking. The purpose of the Phase Two study was to provide an assessment of possible remaining soil gas impacts related to residual groundwater impairments from on- and off-site sources. ENGEO prepared a Remedial Action Plan (RAP) for the mitigation of volatile organic compounds (VOCs) and management of potential petroleum impacted soil.

Ivy Glen, Fremont, CA Mr. Munger is the Principal-in- Charge. ENGEO is providing groundwater sampling, including collecting groundwater samples from existing monitoring wells. Field activities have been conducted by an ENGEO Environmental Engineer. Static water levels are measured in surrounding wells, then checked for the presence of free product or sheen, with no measurable product or sheen found. Prior to gt'oundwater sampling, a well was purged with at least four casing volumes until the field parameters (temperature, conductivity and pH) had stabilized.

Groundwater samples are collected in accordance with ENGEO's standard sampling procedures. Water samples are collected for laboratory testing using a dedicated polyethylene bailer. The samples are decanted into a pre-cleaned 40 ml vial preserved with HCL and cooled in an ice chest until delivery under documented chain-of-custody to Entech Analytical Laboratory in

Santa Clara, Califomia. Samples are analyzed for Volatile Organic Compounds (VOCs) by EPA Method 8260B. Detectable concentrations of VOCs are reported in the laboratory test results.

Cecchini Property, Contra Costa County, CA Mr. Munger provided an agrichemical study. ENGEO is providing geotechnical, environmental, hydrologic, and long-term stOim water Best Management Practices (BMP) consultation services for the project. ENGEO previously performed several surface and subsurface explorations at the site for the purpose of providing geotechnical and environmental design recommendations. The project site is located on Byron Tract at the eastern edge of Contra Costa County. The itTegularly shaped parcel is bounded by Old River to the east, Highway 4 to the south, Discovery Bay to the west, and Indian Slough to the north. The site is agricultural in nature with existing fmm-related structures in the north central part of the site. Numerous small irrigation and drainage ditches traverse the property. The ditches help maintain artificially depressed groundwater levels that serve as a permanent dewatering system.

Discovery Bay West, Tracts 7686 and 8143, Discovery Bay, CA Mr. Munger was Principal-in-Charge. ENGEO provide a modified phase one site assessment addressing the entire 756-acre property. The lots have been rough graded with streets and curb/gutter in place. Most underground utilities are also in place.

River Islands School Site Preliminary Endangerment Assessment, Lathrop, CA Mr. Munger was Principal-in-Charge. ENGEO recently performed a Preliminary Endangerment Assessment for a proposed school site, located in the eastem portion of the River Islands project, a 4,800 acres residential development in Lathrop, Califomia. The PEA was completed for the Banta School District for the proposed River Islands middle and elementary schools. ENGEO conducted environmental sampling of the site near surface soils since the site was historically used for agricultural usages since at least the 1930's. ENGEO determined that residual levels of the pesticides DDE and DDT detected onsite were below the acceptable thresholds and did not pose a threat to the future school site. We concluded the onsite concentrations of mercury, arsenic and lead were consistent with the range and mean concentrations of the background soil results. Based on our evaluation of the soil sampling results, we proposed that no further action was necessary for the proposed school site. ENGEO recently received verbal approval by DISC for the PEA.

Discovery Bay West Villages 4 and 5, Discovery Bay, CA Mr. Munger was Principal-in- Charge. ENGEO provided environmental services for the installation of three groundwater monitoring wells and advancement of six Geoprobe borings at the project site-adjacent to the existing pipeline easement of ±3,400 lineal feet on the property. The purpose of the additional services is to provide further delineation of the extent oflow-Ievel petroleum impacts identified at the site. We also created a letter report presenting the results of the Kinder-Morgan petroleum pipeline assessment.

ENGEO completed a previous petroleum pipeline assessment for the development in 1998. The study did not reveal any appreciable concentrations of target analytes associated with petroleum

ENGEO perfonned a-phase one environmental site assessment at the 12-acre property currently occupied by the Hercules Waste Water Treatment Plant (WWTP), previously operated by the City of Hercules. The property is also a fonner parcel of the Hercules Powder Works site (HPW). Remnant facilities previously associated with the WWTP include a treatment vault, above-ground chemical storage tank, and aeration ponds. Based on the findings of the assessment, there were potential environmental concerns associated with the past and current uses of the propetty:

The lack of environmental documentation prior to the constmction of the Waste Water Treatment Plant and the past history of the site as a part of the Hercules Powder Works represented a potential environmental concern for impacts to the site.

Sampling and analysis data compiled by Questa Engineering in association with the 1991 - 1992 UST and dispenser removal suggests residual soil and groundwater impacts may exist on the property.

The use of hazardous materials and waste associated with the Waste Water Treatment Plant present a potential environmental concern for possible impact to the site.

ASBESTOS SURVEY

Page Number: 1 2100 Stone Valley Road, Alamo I. Introduction North Tower Environmental was retained by Mr. Steve Hart of the San Ramon Valley Fire Protection District to perform an investigative survey for asbestos-containing material (ACM) within the residence and detached garage/in-law located at 2100 Stone Valley Road, in the city of Alamo, California. The purpose of the survey was to locate, sample and analyze visible and accessible suspect ACM within those locations prior to demolition activities. On May 21, 2009, representative bulk samples of suspect materials were collected from various locations at the site. Mr. Miguel Hermida, a Cal/OSHA certified professional, performed the inspection. II. Survey Methodology North Tower Environmental began the survey with a thorough pre-investigation of the structures, which provided the inspector with the opportunity to identify suspect ACM. After the pre-investigation, a detailed inspection was conducted. The inspector collected samples of material including composite samples of drywall and taping mud, texture, plaster, floorings adhesives, black vapor barriers, roofing, ceramic tile with grout, and window caulk Samples collected were placed in plastic bags, sealed and labeled with sample identification numbers. Each sample was given a unique number, which included the sampling date, the sampler's employee number, and the index number of the sample collected on that day. Asbestos samples collected were analyzed by Forensic Analytical Laboratories in Hayward, California. Asbestos bulk samples were examined by Polarized Light Microscopy (PLM) with Dispersion Staining as recommended by the U.S. Environmental Protection Agency. Laboratory results are summarized in Table 1 and are also attached as Appendix A. III. Summary of Results The following asbestos-containing materials were noted in the residence. Drywall and Taping Mud (Sample Number NT3073-052109-04) – The composite result of the drywall and taping mud samples collected from the residence indicated the presence of “trace” (less than one percent) amounts of asbestos. Subsequent Point Count analysis was performed on the “trace” sample in order to determine appropriate disposal requirements. Point Count results confirmed this material contains less than one percent asbestos. • This material is located in the following areas:

- Walls and ceiling in Living Room; - Walls and ceiling in Family Room; - Walls and ceiling in the Kitchen; and - Walls and ceiling in Dining Room.

Page Number: 2 2100 Stone Valley Road, Alamo IV. Conclusions and Recommendations Asbestos-containing wall and ceiling systems were found in the main residence Living Room, Family room, Kitchen and Dining Room. The composite results of the wall and ceiling system (drywall and taping mud) samples collected from the residence indicated the presence of “trace” (less than one percent) amounts of asbestos. Subsequent Point Count analysis confirmed this material contains less than one percent asbestos. The Bay Area Air Quality Management District (BAAQMD) allows for the demolition/removal of building materials when composite sample results contain less than 1 percent asbestos. OSHA regulations; however, require the implementation of certain precautions if a material contains any amount of asbestos. Therefore, OSHA regulations and measures designed to protect workers (i.e. training, respiratory protection, personal protective equipment) must be implemented during the demolition/removal of the sheetrock wall and ceiling systems within the residence.
