5 are presented in Table 1. Sample location maps, indicating the approximate locations of building material samples collected and reported as containing greater than (>) 1% asbestos are provided as Plates 1 through 7. Copies of the analytical laboratory reports and chain-of-custody forms are included in the Appendix. Bulk samples collected during the survey were shipped under chain-of-custody protocol, by Federal Express, to Forensic Analytical Laboratories, Inc. (Forensic Analytical) in Hayward, California. Forensic Analytical is a United States Environmental Protection Agency (USEPA) and California State-certified laboratory and National Voluntary Laboratory Accreditation Program (NVLAP) participant for analysis by Polarized Light Microscopy (PLM). Based upon Kleinfelder s limited ACM survey and subsequent laboratory analysis, the following ACMs have been identified at the following Site structures: Former Automotive New Car Dealership Black coating applied to 2-inch metal piping on the roof; Green 12-inch vinyl floor tile (VFT) and associated black mastic located inside the storage area beneath the east stairway and in the back-counter area; Grey VFT and associated black mastic, located beneath non-acm beige 12-inch VFT, in office No. 8; Brown 12-inch VFT and associated black mastic located in file rooms 1 and 2. Also observed (but not sampled) in the kitchen on the 2 nd floor; White and off-white skim coat applied to gypsum board walls and ceilings throughout the 1 st and 2 nd floors; Joint compound (taping mud) associated with gypsum board wall and ceiling systems throughout the 1 st and 2 nd floors; and White acoustical ceiling texture throughout the 1 st and 2 nd floors /SAC13R0984 Page 2 of 28 October 2, 2013 Copyright 2013 Kleinfelder

6 Former Automotive Used Car Dealership Grey VFT and associated black mastic, located beneath non-acm vinyl sheet flooring (VSF), in the lobby area and hallway; Yellow and black mastic beneath carpet in office spaces; Joint compound (taping mud) associated with gypsum board wall systems located in the hallway and rest rooms; and Acoustical ceiling texture located in the dealership entries, lobby, and offices, and in the southern bays of the detail center. Existing Body Shop Joint compound associated with the gypsum board wall system in the restroom ; and Assumed ACM acoustical ceiling texture located inside work areas enclosed by CMU walls. Based upon Kleinfelder s limited ACM survey and subsequent laboratory analysis, asbestos was not detected in bulk samples collected from the structure located at 477 Quillco Court. Limited LBP Survey Mr. Mark Lee, a California Department of Public Health (CDPH) Certified Lead Inspector/Assessor (No.15884), performed the LBP survey using USEPA, United States Housing and Urban Development (HUD), and CDPH protocols as a general guidance. Eleven paint chip samples were collected from damaged interior and exterior painted and/or coated surfaces suspected to contain lead at the Site. In addition to the paint chip samples, Mr. Lee collected three samples from suspected lead-based pipe wrap materials on vent pipes located on Site structure roofs. A summary of Kleinfelder s lead paint survey results is included in Table 2. Locations of LBP and LCP paint chip samples are provided on Plates 1, 3, 4, 5, and 7. Copies of laboratory analytical results /SAC13R0984 Page 3 of 28 October 2, 2013 Copyright 2013 Kleinfelder

7 and chain of custody forms are provided in the Appendix. The paint chip samples were delivered under chain-of-custody to Forensic Analytical in Hayward, California, a USEPA- and California State-accredited laboratory and Environmental Lab Accreditation Program (ELAP) participant, for lead analysis by Flame Atomic Absorption (Method SW B/7420). Based upon Kleinfelder s limited LBP survey and subsequent review of laboratory analytical results, lead concentrations in the 11 paint chip samples did not exceed 0.5 percent (%) lead by weight (equivalent to 5,000 parts per million [ppm] total lead), the threshold set by USEPA, HUD, and CDPH to define paint as LBP, and therefore are not classified as LBP. Lead concentrations in the three samples of vent pipe wrap ranged from 12% to 26% lead by weight (120,000 to 260,000 ppm total lead); therefore, the vent pipe wrap is classified as LBP. Six paint chip samples were reported by the analytical laboratory as having detectable lead concentrations less than 5,000 ppm; therefore, these paints are considered leadcontaining paint (LCP). The disturbance of these paints/coatings may be regulated by Cal/OSHA under the Lead in Construction Standard, CCR These paints/coatings include: Former Automotive New Car Dealership Beige paint applied to wood beams in the vehicle service bays; and White paint applied to exterior concrete columns. Former Used Car Automotive Dealership White paint applied to exterior concrete walls.

The floor of the PG&E room was unfinished concrete and interior walls were unfinished gypsum board. 2.3 PHYSICAL LIMITATIONS Kleinfelder s surveys included accessible areas of the interiors and/or exteriors of the surveyed structures. The ACM and LBP surveys are considered limited because destructive sampling techniques, including sampling of roofing materials, were not used during the surveys due to varying levels of occupancy and ownership of the structures at the time of the survey assessments. Based on these limitations, there is a possibility that additional ACMs or LBPs may be encountered during building demolition activities in areas inaccessible to Kleinfelder at the time of the surveys (for example, between interstitial walls and ceiling spaces, roof decks, decorative wall and floor coverings, subfloors, attics and crawl spaces, or in underground utility conduits and pipes). If suspect ACMs or LBPs are encountered during proposed demolition activities, they should be assumed to be hazardous until results of an appropriate assessment of the material indicate whether special handling and/or disposal are necessary /SAC13R0984 Page 10 of 28 October 2, 2013 Copyright 2013 Kleinfelder

14 3 ASBESTOS-CONTAINING MATERIALS SURVEY 3.1 ASBESTOS-CONTAINING MATERIALS SURVEY METHODS Kleinfelder personnel performed visual surveys at structures associated with the Site and collected representative bulk samples of building materials suspected to contain asbestos. Mr. Mark Lee, a DOSH, also known as Cal/OSHA CAC (No ), performed the survey. The survey was completed consistent with Federal AHERA methods (40 CFR Part 763) and BAAQMD requirements as a guideline. In accordance with the Contract Scope of Work, destructive inspection and sampling methods were not used for the survey. Areas of homogeneous suspect ACM were identified by the visual inspection of building materials. Bulk samples of suspect ACM were collected using hand tools, such as utility knives, chisels, or putty knives. Up to approximately 2 square inches of material were collected for each sample, which was then placed in either 2-ounce or 4-ounce plastic Whirl-Pak sample bags and labeled with a unique sample identification number directly on the sample bag. Sampling tools were cleaned with soap and water following collection of each sample. Kleinfelder collected a total of 138 representative building material samples during the asbestos survey at the Site. Bulk samples collected during the survey were shipped under chain-of-custody protocol, by Federal Express, to Forensic Analytical in Hayward, California, a USEPA and California State-certified laboratory and NVLAP participant for analysis by PLM. PLM analysis has a limit of quantification (LOQ) of 1 percent (%) asbestos. PLM results reported as trace denote the presence of asbestos below the PLM LOQ. Point count analysis is necessary to confirm asbestos content is less than 1% and will be required by the BAAQMD. Summaries of building material samples collected, sample locations, asbestos content, condition, friability, and area estimates are presented in Table 1. Sample location maps, indicating the approximate locations of building material samples collected and reported as containing greater than (>) 1% asbestos are provided as Plates 1 through 7. Copies of the analytical laboratory reports and chain-of-custody forms are included in the Appendix /SAC13R0984 Page 11 of 28 October 2, 2013 Copyright 2013 Kleinfelder

15 3.2 REGULATORY OVERVIEW FOR ASBESTOS Regulatory oversight for the management, removal, and disposal of ACMs is provided by a variety of Federal, State, and local agencies. The three primary regulations enforced by regulatory agencies that govern various activities (e.g., inspection, assessment, abatement, etc.) relating to ACMs include the following: AHERA, National Emission Standards for Hazardous Air Pollutants (NESHAP), and the Asbestos Construction Safety Standard (as codified in Federal Occupational Safety and Health Administration [OSHA] and Cal/OSHA regulations). USEPA regulations concerning the identification, handling, management, and abatement of ACMs (as defined in the AHERA and NESHAP) are implemented locally by BAAQMD. Both Cal/OSHA and Federal OSHA regulate asbestos as a worker health and safety issue. In addition, the transportation and disposal of asbestos-containing wastes are overseen by the California Environmental Protection Agency s Department of Toxic Substance Control (DTSC). Federal OSHA, USEPA, DTSC, and BAAQMD define ACM as material containing >1% asbestos. The following is a brief description of the three major regulations relating to ACMs Asbestos Hazard Emergency Response Act AHERA (40 CFR Part 763), as implemented by the USEPA, primarily pertains to the assessment and management of ACMs in Kindergarten through Grade 12, non-profit schools. However, many of the procedures, training requirements, and certifications defined by AHERA have become the industry standard for most other facilities. For this survey, AHERA protocols were generally utilized in the identification, assessment, and sampling of building materials suspected of containing asbestos National Emission Standards for Hazardous Air Pollutants The asbestos NESHAP (40 CFR Part 61, Subpart M) is an asbestos standard that protects the general public from asbestos exposure due to renovation or demolition activities. NESHAP requires surveying for suspect materials (as defined above), notifying of intent to renovate or demolish, removing Regulated Asbestos-Containing /SAC13R0984 Page 12 of 28 October 2, 2013 Copyright 2013 Kleinfelder

16 Material (RACM) prior to renovation or demolition, and properly managing asbestoscontaining wastes. A RACM is defined by NESHAP as any of the following: Any friable ACM; A Category I non-friable ACM (such as floor tiles, mastics, and asphalt roofing products) that has become friable or will be subject to sanding, grinding, cutting, or abrading during renovation or demolition activities; and A Category II non-friable ACM (all other non-friable ACMs) that has a high probability of becoming friable during demolition or renovation activities. NESHAP requires that demolition activities be conducted with no visible emissions using wet methods. It is noted that although NESHAP regulates renovation and demolition activities, it does not protect individual workers performing asbestos abatement or provide instructions for how asbestos abatement projects should be performed Asbestos Standard for the Construction Industry Federal OSHA, under its Asbestos Standard for the Construction Industry (29 CFR ), and Cal/OSHA, under California Code of Regulations (CCR) Title 8, Section 1529, regulate asbestos exposure in the work place. This includes persons working in a building containing ACM, as well as asbestos abatement workers/contractors. For abatement workers and contractors, the Asbestos Standard for Construction (i.e., the Construction Standard) regulates the following: Protection of workers and the public during removal of ACM; Medical surveillance requirements for workers; Detailed requirements for how ACMs are to be removed; and Training requirements for abatement personnel. Furthermore, Cal/OSHA defines Asbestos-Containing Construction Material (ACCM) as any building material that contains more than 0.1% asbestos by weight. Building materials presumed or known to contain at least trace amounts (less than 1%, but /SAC13R0984 Page 13 of 28 October 2, 2013 Copyright 2013 Kleinfelder

17 greater than 0.1% by weight) of asbestos should be considered ACCM and managed according to Cal/OSHA regulations (as presented in CCR Title 8, Section 1529). 3.3 ASBESTOS-CONTAINING MATERIALS SURVEY RESULTS Based on Kleinfelder s observations and evaluation of the laboratory analytical reports for samples submitted by Kleinfelder, the following ACMs (defined as materials containing greater than 1% asbestos) were confirmed to be present at the following structures at the Site. Estimated quantities contained below are based on area measurements made by Kleinfelder staff in the field at the time of the survey. The materials and buildings where located include: Former Automotive New Car Dealership Black coating applied to horizontal piping on the roof (Samples DR-1A and DR- 1B) were reported by the laboratory to contain 2% chrysotile asbestos.

The entire wall and ceiling system is estimated to encompass an area of 255 square feet. Acoustical ceiling texture located inside work areas enclosed by CMU walls is assumed to contain greater than 1% asbestos and is classified as friable RACM. This material was not sampled by Kleinfelder because it was not accessible without a mechanical lift; however, the material was sampled during a previous survey (see discussion below) and confirmed to be ACM. This material was /SAC13R0984 Page 16 of 28 October 2, 2013 Copyright 2013 Kleinfelder

20 observed in good condition in the areas it was observed and is estimated to encompass an area of approximately 4,500 square feet. 477 Quillco Court Based on Kleinfelder s limited ACM survey and subsequent laboratory analysis, asbestos was not detected in bulk samples collected from the structure located at 477 Quillco Court. Results of Previous ACM Surveys Subsequent to the completion of the asbestos survey field work, Kleinfelder was provided copies of the following documents by CenterPoint Integrated Solutions, LLC: Asbestos Investigation, 2800 Corby, Santa Rosa, California, prepared by CTL Environmental Services, dated July 20, 1995; Operations & Maintenance Program For Asbestos-Containing Materials, Prestige Auto, prepared by CTL Environmental Services dated November 1995; A letter to Mr. Stephen Hansel, Prestige Imports, from Mr. Tom Jackson, Veale Investments (property owner) dated September 21, 2004 indicating the schedule for abatement of ACMs; and A letter to Tom Jackson, Veale Investments from Charles James, Jakela, Inc., (dba Asbestos Control Center) dated September 21, 2007, indicating the completion of removal of asbestos-containing ceiling texture in various locations of 2800 Corby Avenue, as per contract specifications. Based on Kleinfelder s review of the asbestos survey report and operations and maintenance program documents, the following ACMs were identified during the previous survey: Acoustic spray-on ceiling, body shop, entire building; 12 rust streaked VFT and mastic, body shop rest room; /SAC13R0984 Page 17 of 28 October 2, 2013 Copyright 2013 Kleinfelder

21 Wall board mud, detail shop, entire building; Acoustic spray- on ceiling, detail shop, entire building; Wall board mud, main building, entire building; and Acoustic spray-on ceiling, main building, entire building except 2 nd floor offices and showroom. It is noted that these documents were provided Kleinfelder subsequent to the completion of our asbestos survey field work at the Site. Therefore, materials previously confirmed to contain asbestos in the Site structures were also sampled by Kleinfelder and were reported by the laboratory to contain asbestos. Based upon the results of our survey, each material listed above, with the exception of the 12-inch rust streaked VFT, were observed to still be present in their respective locations /SAC13R0984 Page 18 of 28 October 2, 2013 Copyright 2013 Kleinfelder

22 4 LEAD-BASED PAINT SURVEY 4.1 LEAD-BASED PAINT SURVEY METHODS Kleinfelder personnel performed a survey of painted and/or coated surfaces suspected of containing lead at structures associated with the Site. Mr. Mark Lee, a CDPH Certified Lead Inspector/Assessor (No ), performed the LBP survey using USEPA, HUD, and CDPH protocols as a general guidance. The survey included the visual observation and physical assessment of the painted surfaces. Physical assessment is conducted by assessing if a painted surface is observed to be in an intact or damaged condition. Damaged paint appears as cracked, chipped and/or peeling away from the substrate, as a result of moisture, wear, heat and/or age. Materials that did not exhibit these conditions were noted to be in intact condition. Eleven paint chip samples were collected by Kleinfelder to assess lead content of paints and coatings observed to be in damaged condition. An additional three samples were collected from suspected lead-based pipe wrap materials on vent pipes located on Site structure roofs. Each paint chip sample included a minimum of 2 square inches of painted surface area, but not more than 4 square inches. A clean putty knife was used to scrape paint directly off the substrate. The inspector attempted to remove all layers of paint equally, without including the substrate. Each paint chip sample was placed in a 2-ounce plastic Whirl-Pak sample bag and labeled with a unique sample identification number directly on the sample bag. The paint chip samples were delivered under chain-of-custody to Forensic Analytical in Hayward, California, a USEPA- and California State-accredited laboratory and ELAP participant, for lead analysis by Flame Atomic Absorption (Method SW B/7420). A summary of Kleinfelder s lead paint survey results is included in Table 2. Locations of LBP and LCP paint chip samples are provided on Plates 1, 3, 4, 5, and 7. Copies of laboratory analytical results and chain of custody forms are provided in the Appendix /SAC13R0984 Page 19 of 28 October 2, 2013 Copyright 2013 Kleinfelder

23 4.2 REGULATORY OVERVIEW FOR LEAD-BASED PAINTS The USEPA, HUD, and CDPH define LBP as paint containing greater than 0.5% lead by weight or 5,000 parts per million (ppm) of total lead by laboratory analysis, or a lead content of 1.0 milligrams per square centimeter (mg/cm 2 ) by XRF measurement. Federal OSHA and Cal/OSHA regulations (Lead Construction Standard) do not provide a definition for lead-based paint but refer to the USEPA, HUD, and CDPH criteria mentioned above. Cal/OSHA is primarily concerned with worker protection, and regulates any amount of lead contained within painted building components. Both Federal OSHA and Cal/OSHA provide an Action Level (AL) of 30 micrograms per cubic meter (µg/m 3 ) of airborne lead for an 8-hour, time-weighted average. Specific worker training and worker protection are to be provided by employers if workers are exposed to airborne lead at or above the AL. Additionally, both Federal OSHA and Cal/OSHA provide a Permissible Exposure Limit (PEL) for worker exposure to airborne lead particles of 50 µg/m 3 of air for an 8-hour, time-weighted average. According to Cal/OSHA (CCR Title 8, Section ), employers may assume that disturbance of coatings or materials shown to contain less than 0.06% lead by weight (equivalent to 600 ppm lead) will not result in exposures above the applicable AL as long as workers are not performing the Cal/OSHA designated trigger tasks (such as manual demolition, manual sanding or scraping, or abrasive blasting). However, renovation or demolition activities that include materials with lead in any concentration could, under certain circumstances, trigger Federal OSHA and Cal/OSHA regulations. The concentrations of airborne lead generated by disturbing paints at the Site would vary based upon several factors, including the type of activity (including "trigger tasks") and the severity of disturbance to the building materials. Measurement of airborne lead concentrations would require air monitoring during building material disturbance by a trained lead professional. 4.3 LEAD-BASED PAINT SURVEY RESULTS Based upon Kleinfelder s limited LBP survey and subsequent review of laboratory analytical results, the following paints or coatings were reported by the laboratory as containing greater than 0.5% lead by weight or 5,000 ppm of total lead, and are classified as LBP: /SAC13R0984 Page 20 of 28 October 2, 2013 Copyright 2013 Kleinfelder

24 Grey metal wrap (Sample DP-2) applied to a vent pipe near EF-3 on the former Automotive New Car Dealership roof was reported by the analytical laboratory to contain 120,000 ppm total lead or 12% lead by weight and is therefore considered a lead-based material. The material was observed to be in good condition in the area observed. Lead wrap was observed at 2 roof penetrations on the roof of the structure. Metal wrap (Sample UCP-1) applied to a roof penetration on the roof of the former Automotive Used Car Dealership was reported by the analytical laboratory to contain 260,000 ppm total lead or 26% lead by weight and is therefore considered a lead-based material. The material was observed in good condition in the area observed. Lead wrap was observed at 39 roof penetrations. Metal wrap (Sample BSP-1) applied to a roof penetration on the roof of the existing Body Shop was reported by the analytical laboratory to contain 150,000 ppm total lead or 15% lead by weight and is therefore considered a lead-based material. The material was observed in good condition in the area observed. Lead wrap was observed at 2 roof penetrations. Six paint chip samples were reported by the analytical laboratory as having detectable lead concentrations less than 5,000 ppm, and are therefore considered LCP. The disturbance of these paints/coatings may be regulated by Cal/OSHA under the Lead in Construction Standard, CCR These paints/coatings include: Former Automotive New Car Dealership Beige paint applied to wood beams in the vehicle service bays (Sample DP-3) was reported by the analytical laboratory to contain 1,800 ppm total lead or 0.18% lead by weight. The paint was observed to be in poor condition. White paint applied to exterior concrete columns (Sample DP-4) was reported by the laboratory to contain 590 ppm total lead or 0.059% lead by weight.

Planned renovation, demolition or general work activities, which may disturb building materials containing asbestos or components with LBPs or coatings, should be performed by properly trained and qualified personnel in accordance with all Federal, State, and local regulations, as implemented by Cal/OSHA, Federal OSHA, USEPA, DTSC, and BAAQMD. Prior to future demolition work, Kleinfelder recommends that the following actions be taken: Additional samples should be collected from areas of the sites that were not accessed or assessed during Kleinfelder s limited surveys, using destructive sample collection methods. These areas include interstitial walls and ceiling spaces, roof decks, behind and under decorative wall and floor coverings, subfloors, attics and crawl spaces. This additional sampling should be performed by a Cal/OSHA CAC or CSST under the supervision of a CAC subsequent to the acquisition of the properties by the client and prior to the commencement of planned demolition activities. A specification produced by a Cal/OSHA CAC and CDPH-certified Lead Project Designer or Project Monitor for abatement of the ACMs and LBPs/LCPs should be prepared and should be the basis for selecting contractors to perform the abatement work. Prior to building demolition, the owner of the property should retain a State of California-licensed ACM/LBP abatement contractor to perform abatement of the ACMs and LBPs that could potentially be disturbed during planned demolition activities at the Site. The general contractor for the project may be a source of information concerning locally licensed abatement contractors. Kleinfelder can also provide names of licensed and qualified abatement contractors in the area upon request /SAC13R0984 Page 25 of 28 October 2, 2013 Copyright 2013 Kleinfelder

29 Submittal of a BAAQMD Notification of Demolition or Asbestos Removal is required for every demolition in BAAQMD s jurisdiction, even when no ACMs are present, and for each asbestos removal project where the amount of ACM to be removed is equal to or greater than 100 square (or linear) feet. Prior to the initiation of abatement or demolition work, the abatement or demolition contractor must complete the Notification of Demolition or Asbestos Removal form and submit it to the BAAQMD at least 10 business days before the start of abatement or demolition. The BAAQMD will return the form, with a notification number added, to the abatement or demolition contractor, depending on who submitted the form. Written notification to the local Cal/OSHA district office will be required from the selected asbestos/lead abatement contractor regarding its Intent to Conduct Asbestos Related Work and/or Intent to Conduct Lead-Related Work. These notifications should be submitted at least 24 hours in advance of performing the respective asbestos-related or lead-related work. Notification should be provided to contractor and subcontractor personnel as to the presence of RACMs, ACMs and LBP at the Site /SAC13R0984 Page 26 of 28 October 2, 2013 Copyright 2013 Kleinfelder
