EXECUTIVE SUMMARY

AEI Consultants (AEI) was retained by CCIG to conduct a Phase I Environmental Site Assessment (ESA), in general conformance with the scope and limitations of ASTM Standard Practice E1527-05 and the Environmental Protection Agency Standards and Practices for All Appropriate Inquiries (40 CFR Part 312) for the property located at 7700 Edgewater Drive in the City of Oakland, Alameda County, California. Any exceptions to, or deletions from, this practice are described in Section 1.3 of this report.

PROPERTY DESCRIPTION The subject property, which consists of four office buildings, is located on the northeast side of Edgewater Drive in a commercial area of Oakland, California. The property totals approximately 10.6 acres and is improved with four two-story wooden frame, slab-on-grade buildings totaling approximately 204,616 square feet. The subject property is currently occupied by several tenants that use the property for administrative and educational purposes. In addition to the subject property buildings, the property is improved with courtyards, asphalt-paved parking areas, and landscaped areas.

During the site reconnaissance, three 55-gallon drums of a non-acid disinfectant bathroom cleaner were observed in a janitorial storage area. No environmental concerns associated with the storage and/or use of these materials were noted during the site reconnaissance or during the review of regulatory records. Please refer to Section 7.1 for additional information.

The subject property was developed with the current improvements from 1971 through 1973. Prior to the current site improvements, the subject property was undeveloped marshland that was filled with imported soils in the late 1940s or 1950s. The property was vacant until development of the current office complex in the early 1970s. Since construction, the current office plaza has been occupied for use as offices and educational facilities. No historical tenants suspected of using hazardous materials were identified. Contamination identified in the fill materials is discussed in the Findings segment below.

The subject property was not identified during the regulatory database search.

The immediately surrounding properties consist of the following:

Direction from Site Address-Tenant/Use Northwest Drainage channel followed by Raimin Instrument LLC (7500 Edgewater Drive) Southeast BIR Polymers, Inc. (7750 Edgewater Drive) D.M. Figley Co. Inc. (463-465 Roland Way) Multi-tenant industrial (469-475 Roland Way) Northeast Key Source International (7711 Oakport Street) Multi-tenant industrial (7717-7723 Oakport Street) Hertz Equipment Rental (7727 Oakport Street) Southwest Edgewater Drive followed by: Office building (7699 Edgewater Drive) State of California building (7717 Edgewater Drive)

The adjacent site to the northeast at 7727 Oakport Street was listed in the regulatory database as a Leaking Underground Storage Tank (LUST) site, an Alameda County Contaminated Sites (Alameda County CS) site, and on several historical underground storage tank (UST) databases

Project No. 315265 December 20, 2012 Page ii

(HIST CORTESE, CA FID UST, SWEEPS UST, HIST UST). These listings are further discussed in Section 5.1.

Based upon topographic map interpretation, the direction of groundwater flow beneath the subject property is inferred to be to the west. Based on groundwater monitoring data for the nearby site at 7101 Edgewater Drive, groundwater is presumed to be present at an estimated depth of less than 15 feet below ground surface (bgs).

FINDINGS Recognized Environmental Conditions (RECs) are defined by the ASTM Standard Practice E1527- 05 as 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 any hazardous substances or petroleum products into structures on the property or into the ground, groundwater, or surface water of the property. AEI’s assessment has revealed the following RECs associated with the subject property or nearby properties:

A subsurface investigation was performed at the subject property in 1991, during which 19 soil borings were advanced in the northern parking lot at depths ranging from 2.5 to 6.5 feet below ground surface (bgs). Analysis of these samples indicated up to 1,600 parts per million (ppm) total petroleum hydrocarbons as motor oil (TPHmo). A groundwater monitoring well was installed and sampled for the presence of TPHmo and BTEX (benzene, toluene, ethylbenzene and xylenes). Very low levels of TPHmo and no detectable levels of BTEX were identified in the well. Further work was requested by the Alameda County Department of Environmental Health Services (ACDEHS) to delineate the extent of the contamination and determine if the source was from 7700 Edgewater Drive. Additional subsurface investigation at the subject property and approximately 50 feet north of the subject property revealed higher levels of TPHmo in both soil and groundwater in the sample locations to the north. In 1991, the consultant proposed to the ACDEHS that the source of the contamination was from the fill materials brought onsite and not from onsite activities at 7700 Edgewater Drive. The ACDEHS concurred with this assessment, and stated that there was no guideline policy available from the Regional Water Quality Control Board (RWQCB) regarding contaminated bay fill. No further work was required in the absence of a guideline policy for contaminated fill.

Historical Recognized Environmental Conditions (HRECs) are defined by the ASTM Standard Practice E1527-05 as an environmental condition which in the past would have been considered a recognized environmental condition, but which may or may not be considered a recognized environmental condition currently. AEI’s assessment has revealed the following HRECs associated with the subject property or nearby properties:

• No on-site HRECs were identified during the course of this assessment.

De Minimis Environmental Conditions include environmental concerns identified by AEI that warrant discussion but do not qualify as RECs, as defined by the ASTM Standard Practice E1527-05. AEI’s assessment has revealed the following de minimis environmental conditions associated with the subject property or nearby properties:

• No on-site de minimis environmental conditions were identified during the course of this assessment.

Project No. 315265 December 20, 2012 Page iii

Business Environmental Risks (BERs) include risks which can have a material environmental or environmentally-driven impact on the business associated with the current or planned use of the subject property, not necessarily limited to those environmental issues required to be investigated in the standard ASTM scope. BERs may affect the liabilities and financial obligations of the client, the health & safety of site occupants, and the value and marketability of the subject property. AEI’s assessment has revealed the following BERs associated with the subject property or nearby properties:

• Two historical occupants of the subject property, JKD Printing Service in 1990 and Mr. Copy Smart Document Solutions, Oakland, in 2010 appear to have been printing facilities. Printing operations can pose an environmental concern based on the historical use of solvents, metal-containing inks, and photo development chemicals employed during these activities. However, no hazardous material usage has been reported to the oversight agencies for the subject property, and the scale of printing operations within these businesses is expected to have been small. Further, no drains or other potential subsurface conduits were noted or reported within the subject property buildings, with the exception of within the bathroom areas. Based on this information and the relatively short duration of occupancy of each business, these historical occupants are not expected to constitute a significant environmental concern.

• The subject property was inspected for the presence of asbestos-containing materials (ACMs) in 1990. Tested areas included roofs, tenant improvements (taping and joint compound), fire doors, and 12” floor tiles. ACMs were identified in roofing materials, fire door insulation, and floor tile mastic. An asbestos abatement was performed in 1990 and 1991. Asbestos-containing floor tiles and spray-on ceiling material from the first floor bathrooms and the second floor corridor areas was removed in February, 1991, and approximately 6,000 square feet of asbestos-containing floor tile, mastic and particle floorboard was removed in July, 1991. In February, 1993, asbestos flooring mastic found in Suites 360 and 400 in Building B was removed. Additional limited asbestos screening was performed in 1998 in Building D. Chrysotile asbestos was detected in four of ten samples, collected from damaged resilient sheet flooring under floor tiles in the men’s 2nd-floor restroom; spray-on ceiling texture in the northeast stairwell and hallway; and brown cove base mastic in Room 803. Based on the presence of ACMs, AEI recommends the implementation of an Operations and Maintenance (O & M) Plan which stipulates that the repair and maintenance of ACMs should be performed to protect the health and safety of the building occupants.

• Due to the age of the subject property buildings, there is a potential that lead-based paint (LBP) is present. All observed painted surfaces were in good condition and are not expected to pose a health and safety concern to the occupants of the subject property at this time. Local regulations may apply to lead-based paint in association with building demolition/renovations and worker/occupant protection. Actual material samples would need to be collected or an XRF survey performed in order to determine if LBP is present. It should be noted that construction activities that disturb materials or paints containing any amount of lead may be subject to certain requirements of the OSHA lead standard contained in 29 CFR 1910.1025 and 1926.62.

CONCLUSIONS, OPINIONS AND RECOMMENDATIONS We have performed a Phase I Environmental Site Assessment for the property located at 7700 Edgewater Drive in the City of Oakland, Alameda County, California, in general conformance

Project No. 315265 December 20, 2012 Page iv with the scope and limitations of ASTM Standard Practice E1527-05 and the Environmental Protection Agency Standards and Practices for All Appropriate Inquiries (40 CFR Part 312). Any exceptions to, or deletions from, this practice are described in Section 1.3 of this report. This assessment has revealed evidence of an REC in connection with the property. However, no further action appears warranted at this time.

1.0 INTRODUCTION

This report documents the methods and findings of the Phase I Environmental Site Assessment (ESA) performed in general conformance with the scope and limitations of ASTM Standard Practice E1527-05 and the Environmental Protection Agency Standards and Practices for All Appropriate Inquiries (40 CFR Part 312) for the property located at 7700 Edgewater Drive in the City of Oakland, Alameda County, California (Figure 1: Site Location Map, Figure 2: Site Map, and Appendix A: Property Photographs).

1.1 SCOPE OF WORK The purpose of the Phase I Environmental Site Assessment is to assist the client in identifying potential environmental liabilities associated with the presence of any hazardous substances or petroleum products, their use, storage, and disposal at and in the vicinity of the subject property, as well as regulatory non-compliance that may have occurred at the subject property. Property assessment activities focused on: 1) a review of federal, state, tribal and local databases that identify and describe underground fuel tank sites, leaking underground fuel tank sites, hazardous waste generation sites, and hazardous waste storage and disposal facility sites within the ASTM approximate minimum search distance; 2) a property and surrounding site reconnaissance, and interviews with the past and present owners and current occupants and operators to identify potential environmental contamination; and 3) a review of historical sources to help ascertain previous land use at the site and in the surrounding area.

The goal of AEI Consultants in conducting the Phase I Environmental Site Assessment was to identify the presence or likely presence of any hazardous substances or petroleum products on the property that may indicate an existing release, a past release, or a material threat of a release of any hazardous substance or petroleum product into the soil, groundwater, or surface water of the property.

1.2 SIGNIFICANT ASSUMPTIONS The following assumptions are made by AEI Consultants in this report. AEI Consultants relied on information derived from secondary sources including governmental agencies, the client, designated representatives of the client, property contact, property owner, property owner representatives, computer databases, and personal interviews. AEI Consultants has reviewed and evaluated the thoroughness and reliability of the information derived from secondary sources including government agencies, the client, designated representatives of the client, property contact, property owner, property owner representatives, computer databases, or personal interviews. It appears that all information obtained from outside sources and reviewed for this assessment is thorough and reliable. However, AEI cannot guarantee the thoroughness or reliability of this information.

Groundwater flow and depth to groundwater, unless otherwise specified by on-site well data, or well data from adjacent sites are assumed based on contours depicted on the United States Geological Survey topographic maps. AEI Consultants assumes the property has been correctly and accurately identified by the client, designated representative of the client, property contact, property owner, and property owner’s representatives.

Project No. 315265 December 20, 2012 Page 1

1.3 LIMITATIONS Property conditions, as well as local, state, tribal and federal regulations can change significantly over time. Therefore, the recommendations and conclusions presented as a result of this study apply strictly to the environmental regulations and property conditions existing at the time the study was performed. Available information has been analyzed using currently accepted assessment techniques and it is believed that the inferences made are reasonably representative of the property. AEI Consultants makes no warranty, expressed or implied, except that the services have been performed in accordance with generally accepted environmental property assessment practices applicable at the time and location of the study.

Considerations identified by ASTM as beyond the scope of a Phase I ESA that may affect business environmental risk at a given property include the following: asbestos-containing materials, radon, lead-based paint, lead in drinking water, wetlands, regulatory compliance, cultural and historic resources, industrial hygiene, health and safety, ecological resources, endangered species, indoor air quality, mold, vapor intrusion, and high voltage lines. These environmental issues or conditions may warrant assessment based on the type of the property transaction; however, they are considered non-scope issues under ASTM Standard Practice E1527-05.

If requested by the client, these non-scope issues are discussed in Section 7.2. Otherwise, the purpose of this assessment is solely to satisfy one of the requirements for qualification of the innocent landowner defense, contiguous property owner or bona fide prospective purchaser under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). ASTM Standard Practice E1527-05 and the EPA Standards and Practices for All Appropriate Inquiries (40 CFR Part 312) constitute the “all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or customary practice” as defined in:

1) 42 U.S.C § 9601(35)(B), referenced in the ASTM Standard Practice E1527-05.

2) Sections 101(35)(B) (ii) and (iii) of CERCLA and referenced in the EPA Standards and Practices for All Appropriate Inquiries (40 CFR Part 312).

3) 42 U.S.C. 9601(40) and 42 U.S.C. 9607(q).

The Phase I Environmental Site Assessment is not, and should not be construed as, a warranty or guarantee about the presence or absence of environmental contaminants that may affect the property. Neither is the assessment intended to assure clear title to the property in question. The sole purpose of assessment into property title records is to ascertain a historical basis of prior land use. All findings, conclusions, and recommendations stated in this report are based upon facts, circumstances, and industry-accepted procedures for such services as they existed at the time this report was prepared (i.e., federal, state, and local laws, rules, regulations, market conditions, economic conditions, political climate, and other applicable matters). All findings, conclusions, and recommendations stated in this report are based on the data and information provided, and observations and conditions that existed on the date and time of the property visit.

Responses received from local, state, or federal agencies or other secondary sources of information after the issuance of this report may change certain facts, findings, conclusions, or circumstances to the report. A change in any fact, circumstance, or industry-accepted

Project No. 315265 December 20, 2012 Page 2

procedure upon which this report was based may adversely affect the findings, conclusions, and recommendations expressed in this report.

1.4 LIMITING CONDITIONS The performance of this Phase I Environmental Site Assessment was limited by the following condition:

• Due to the size of the property, a representative sample of interior spaces was inspected by AEI. Due to the use of the property for administrative/office and educational purposes, this limited inspection method is expected to be adequate for the purposes of this assessment.

• On December 12, 2012, the Oakland Fire Department (OFD) was contacted for information on the subject property in order to identify historical tenants, property use and/or hazardous materials handling. As of this writing, AEI has not received a response from the OFD. Based on the quality of information obtained from other sources, the lack of information, if existent, from the OFD is not expected to significantly alter the conclusions of this investigation.

1.5 DATA GAPS AND DATA FAILURE According to ASTM E1527-05, data gaps occur when the Environmental Professional is unable to obtain information required, despite good faith efforts to gather such information.

Data failure is one type of data gap. According to ASTM E1527-05 “data failure occurs when all of the standard historical sources that are reasonably ascertainable and likely to be useful have been reviewed and yet the objectives have not been met”. Pursuant to ASTM Standards, historical sources are required to document property use back to the property’s first developed use or back to 1940, whichever is earlier.

No data gaps were identified during the course of this assessment.

1.6 RELIANCE All reports, both verbal and written, are for the benefit of CCIG. This report has no other purpose and may not be relied upon by any other person or entity without the written consent of AEI. Either verbally or in writing, third parties may come into possession of this report or all or part of the information generated as a result of this work. In the absence of a written agreement with AEI granting such rights, no third parties shall have rights of recourse or recovery whatsoever under any course of action against AEI, its officers, employees, vendors, successors or assigns. Reliance is provided in accordance with AEI’s Proposal and Standard Terms & Conditions executed by CCIG on December 11, 2012. The limitation of liability defined in the Terms and Conditions is the aggregate limit of AEI’s liability to the client and all relying parties.

2.0 SITE AND VICINITY DESCRIPTION

2.1 SITE LOCATION AND DESCRIPTION The subject property, which consists of four office buildings, is located on the northeast side of Edgewater Drive in Oakland, California. The property totals approximately 10.6 acres and is improved with four two-story wooden frame, slab-on-grade buildings totaling approximately 204,616 square feet. The subject property is currently occupied by several tenants that use the property for administrative and educational purposes. In addition to the subject property buildings, the property is improved with courtyards, asphalt-paved parking areas, and landscaped areas.

The subject property was not identified during the regulatory database search.

The Assessor’s Parcel Number (APN) for the subject property is 42-4435-1-11. Heating and cooling systems on the subject property are fueled by natural gas and electricity provided by Pacific Gas & Electric (PG&E), and potable water and sewage disposal are provided by municipal services.

Refer to Figure 1: Site Location Map, Figure 2: Site Map, and Appendix A: Property Photographs for site location.

2.2 SITE AND VICINITY CHARACTERISTICS The immediately surrounding properties consist of the following:

2.3 PHYSICAL SETTING Geology: According to information obtained from the United States Geological Survey (USGS), the area surrounding the subject property is underlain by saline marsh deposits of the Holocene era. Based on a review of aerial photographs and regulatory records reviewed in connection with prior reports, the subject property formerly consisted of bay marshes that were filled in the late 1940s or 1950s. Contamination has been identified in association with these materials, as is discussed in Section 6.3.

3.0 HISTORICAL REVIEW OF SITE AND VICINITY

3.1 HISTORICAL SUMMARY Reasonably ascertainable standard historical sources as outlined in ASTM Standard E1527-05 were used to determine previous uses and occupancies of the subject property that are likely to have led to RECs in connection with the subject property. A chronological summary of historical data found, including but not limited to aerial photographs, historic city directories, Sanborn fire insurance maps and agency records is as follows:

Subject Property Date Range Source(s) Description/Use 1939-1946 Bay marsh Aerial Photographs, Previous Reports 1958-1965 Filled marshland; vacant Aerial Photographs, Previous Reports Current office complex 1971-1973 Building Records, Assessor’s Records, Interviews constructed Aerial Photographs, Building Records, City Directories, 1973-2012 Office complex Previous Reports, Interviews, Onsite Observations

No historical tenants suspected of using hazardous materials were identified. Contamination identified in the fill materials is discussed in Section 6.3.

If available, copies of historical sources are provided in the report appendices.

3.2 AERIAL PHOTOGRAPH REVIEW AEI Consultants reviewed aerial photographs of the subject property and surrounding area. Aerial photographs were reviewed for the following years:

Date(s) Scale Subject Property Description Surrounding Area Descriptions 1939 1” = 555’ Tidal marshland Tidal marshland 1946 1” = 655’ 1958 1” = 555’ Filled, undeveloped land Northeast: Filled, undeveloped land 1965 1” = 333’ Northwest: Drainage channel followed by filled, undeveloped land Southeast: Filled, undeveloped land Southwest: Filled, undeveloped land 1982 1” = 690’ Office complex Northeast: Commercial or industrial 1993 1” = 666’ buildings 1998 1” = 666’ Northwest: Drainage channel followed by filled, undeveloped land Southeast: Commercial or industrial buildings Southwest: Commercial or industrial building; vacant land

2005 1” = 528’ Office complex Northeast: Commercial or industrial buildings Northwest: Drainage channel followed by commercial or industrial building Southeast: Commercial or industrial buildings Southwest: Commercial or industrial building; vacant land

3.3 SANBORN FIRE INSURANCE MAPS Sanborn Fire Insurance maps were developed in the late 1800s and early 1900s for use as an assessment tool for fire insurance rates in urbanized areas. A search was made of the UC Berkeley McCone Earth Sciences Library collection and Seattle Public Library online collection of Sanborn Fire Insurance maps.

Sanborn map coverage was not available for the subject property.

3.4 CITY DIRECTORIES A search of historic city directories was conducted for the subject property at the Oakland Public Library. Directories were available and reviewed for the years 1973, 1975, 1981, 1985, 1990, 1995, 2000, 2005 and 2010. Various commercial and office tenants were listed at the subject property in all reviewed directories.

Two historical occupants, JKD Printing Service in 1990 and Mr. Copy Smart Document Solutions, Oakland, in 2010 appear to have been printing facilities. Printing operations can pose a potential environmental concern based on the historical use of solvents, metal-containing inks, and photo development chemicals employed during these activities. However, no hazardous material usage has been reported to the oversight agencies for the subject property, and the scale of printing operations within these businesses is expected to have been small. Further, no drains or other potential subsurface conduits were noted or reported within the subject property buildings, with the exception of within the bathroom areas. Based on this information and the relatively short duration of occupancy of each business, these historical occupants are not expected to constitute a significant environmental concern.

Refer to Appendix C: Historical Sources for a complete listing of tenants identified.

3.5 HISTORICAL TOPOGRAPHIC MAPS In accordance with our approved scope of services, historical topographic maps were not reviewed as a part of this assessment.

3.6 CHAIN OF TITLE In accordance with our approved scope of services, a Chain of Title search was not performed as part of this assessment.

4.0 REGULATORY AGENCY RECORDS REVIEW

4.1 REGULATORY AGENCIES Local and state agencies, such as environmental health departments, fire prevention bureaus, and building and planning departments are contacted to identify any current or previous reports of hazardous materials use, storage, and/or unauthorized releases that may have impacted the subject property. In addition, information pertaining to Activity and Use Limitations (AULs), defined as legal or physical restrictions, or limitations on the use of, or access to, a site or facility, is requested.

4.1.1 HEALTH DEPARTMENT On December 13, 2012, AEI contacted the Alameda County Department of Environmental Health Services (ACDEHS) for information on the subject property and nearby sites of concern. Files at this agency may contain information regarding hazardous materials storage, as well as information regarding unauthorized releases of petroleum hydrocarbons or other contaminants that may affect the soil or groundwater in the area.

No information indicating current or prior use or storage of hazardous materials, or the existence of AULs was on file for the subject property with the ACDEHS. However, records were apparently available during the performance of a previous environmental assessment in 2004, as is discussed in Section 6.3. These documents may have since been purged from ACDEHS files.

4.1.2 FIRE DEPARTMENT On December 12, 2012, the Oakland Fire Department (OFD) was contacted for information on the subject property in order to identify historical tenants, property use and/or hazardous materials handling. As of this writing, AEI has not received a response from the OFD. Based on the quality of information obtained from other sources, the lack of information, if existent, from the OFD is not expected to significantly alter the conclusions of this investigation.

4.1.3 BUILDING DEPARTMENT On December 18, 2012, AEI visited the Oakland Building Department (OBD) for information on the subject property in order to identify historical tenants and property use. Please refer to the following table for a listing of permits reviewed:

Building Permits Reviewed Year(s) Owner/Applicant Description of Permit/Building Use 1970 Herman Christensen & Son Application to construct office building 1971, Unknown Certificates of occupancy 1972 1973-2012 Various (Edgewater Park Plaza; Tenant improvements administrative/educational tenants) Electrical permits Mechanical permits Sign permits Fire sprinkler permits

No information indicating current or prior use or storage of hazardous materials, or the existence of AULs was on file for the subject property with the OBD.

Project No. 315265 December 20, 2012 Page 8

4.1.4 PLANNING DEPARTMENT On December 18, 2012, AEI visited the Oakland Planning Department (OPD) for information on the subject property in order to identify AULs associated with the subject property.

No information indicating the existence of AULs was on file for the subject property with the OPD.

4.1.5 COUNTY ASSESSOR OFFICE On December 12, 2012, AEI contacted the Alameda County Assessor’s Office (ACAO) for information on the subject property in order to determine the earliest recorded date of development and use.

According to the ACAO, the earliest recorded date of development on subject property was 1973.

4.1.6 DEPARTMENT OF OIL AND GAS Department of Oil and Gas (DOG) maps concerning the subject property and nearby properties were reviewed. DOG maps contain information regarding oil and gas development.

According to the DOG map, there are no oil or gas wells within 500 feet of the subject property. No environmental concerns were noted during the DOG map review.

4.1.7 OTHER AGENCIES SEARCHED Regional Water Quality Control Board

On December 12, 2012, AEI accessed records with the State Water Resources Control Board (SWRCB) online GeoTracker database for information on the subject property or nearby sites of concern. Files at this agency may contain information regarding hazardous materials storage, as well as information regarding unauthorized releases of petroleum hydrocarbons or other contaminants that may affect the soil or groundwater in the area.

No information indicating current or prior use or storage of hazardous materials, or the existence of AULs was on file for the subject property with the SWRCB.

Department of Toxic Substances Control

On December 12, 2012, AEI accessed records with the California Department of Toxic Substances Control (DTSC) online EnviroStor database for information on the subject property or nearby sites of concern. Files at this agency may contain information regarding hazardous materials storage, as well as information regarding unauthorized releases of petroleum hydrocarbons or other contaminants that may affect the soil or groundwater in the area.

No information indicating current or prior use or storage of hazardous materials, or the existence of AULs was on file for the subject property with the DTSC.

Project No. 315265 December 20, 2012 Page 9

5.0 REGULATORY DATABASE RECORDS REVIEW

AEI contracted Environmental Data Resources (EDR) to conduct a search of federal, state, tribal, and local databases containing known and suspected sites of environmental contamination. The number of listed sites identified within the approximate minimum search distance (AMSD) from the Federal and State environmental records database listings specified in ASTM Standard E 1527-05 are summarized in the following table. A copy of the regulatory database report is included in Appendix B of this report. The subject property was not identified in the databases reviewed. In determining if a site is a potential environmental concern to the subject property in the records summary table below, AEI has applied the following criteria to classify the site(s) as low concern: 1) the site(s) only hold an operating permit (which does not imply a release), 2) the site(s) have been granted “No Further Action” by the appropriate regulatory agency, and/or 3) based upon AEI’s review, the distance and/or topographic position relative to the subject property reduce the level of risk associated with the site(s).

In September, 1995, five groundwater monitoring wells were installed to assess impacts to soil and groundwater from former fuel storage tanks and a pump island at the site. Groundwater monitoring events were intermittent between 1995 and 1998, and occurred annually between 2001 and 2005. Sampling conducted in 2012 revealed up to 2,500 parts per billion (ppb) gasoline-range organics (GRO) and 470 ppb diesel-range organics (DRO). Based on the relative distance of this site from the subject property, the releases are not expected to constitute a significant environmental concern.

The SLIC listing for this site appears to be erroneous, and actually refers to a property at 2601 East Imperial Highway in Lynwood, California. Case details indicate that releases at this site were related to the manufacture of ink, paints and lacquers from 1947 to 1971. Agency records for the Caltrans site at 555 Hegenberger Road indicate that this site is associated with a LUST listing, not SLIC.

6.0 INTERVIEWS AND USER PROVIDED INFORMATION

6.1 INTERVIEWS Pursuant to ASTM E1527-05, the following interviews were performed during this investigation in order to obtain information indicating RECs in connection with the subject property.

6.1.1 INTERVIEW WITH OWNER The subject property owner, Polidez International, represented by Ms. Rose Marcelino, Assistant Property Manager, was interviewed on December 18, 2012. Ms. Marcelino has been associated with the subject property for 6 months. Ms. Marcelino was asked if she was aware of any of the following: Any pending, threatened, or past litigation relevant to hazardous substances or petroleum products in, on, or from the property. Yes X No Any pending, threatened or past administrative proceedings relevant to hazardous substances or petroleum products in, on, or from the property. Yes X No Any notices from any governmental entity regarding any possible violation of environmental laws or possible liability relating to hazardous substances or petroleum products. Yes X No Any incidents of flooding, leaks, or other water intrusion, and/or complaints related to indoor air quality. Yes X No

6.1.2 INTERVIEW WITH KEY SITE MANAGER The key site manager, Ms. Brittney Crossland, Building Engineer, was interviewed during the site visit on December 18, 2012. Ms. Crossland has been associated with the subject property for 1.5 years. Ms. Crossland provided general information regarding historic and current operations at the subject property. Ms. Crossland was asked if she was aware of any of the following: Any pending, threatened, or past litigation relevant to hazardous substances or petroleum products in, on, or from the property. Yes X No Any pending, threatened or past administrative proceedings relevant to hazardous substances or petroleum products in, on, or from the property. Yes X No Any notices from any governmental entity regarding any possible violation of environmental laws or possible liability relating to hazardous substances or petroleum products. Yes X No Any incidents of flooding, leaks, or other water intrusion, and/or complaints related to indoor air quality. Yes X No

6.1.3 PAST OWNERS, OPERATORS AND OCCUPANTS Interviews with past owners and occupants regarding historical onsite operations were not reasonably ascertainable. However, based on information obtained from other sources including aerial photographs, building records, city directories, and previous reports, it is likely that the information provided by past owners and operators would have been duplicative.

6.1.4 INTERVIEW WITH OTHERS Information obtained during interviews with local government officials is incorporated into the appropriate segments of this section.

Project No. 315265 December 20, 2012 Page 12

6.2 USER PROVIDED INFORMATION User provided information is intended to help identify the possibility of RECs in connection with the subject property. According to ASTM E1527-05 and EPA's AAI Rule, certain items should be researched by the prospective landowner or grantee, and the results of such inquiries may be provided to the environmental professional. The responsibility for qualifying for Landowner Liability Protections (LLPs) by conducting the inquiries ultimately rests with the User, and providing the information to the environmental professional would be prudent if such information is available.

The User did not complete the ASTM User questionnaire or provide the User information to AEI. AEI assumes that qualification for the LLPs is being established by the User in documentation outside of this assessment.

6.3 PREVIOUS REPORTS Documentation was provided to AEI by CCIG during this assessment. A summary of this information follows:

Physical Assessment, Edgewater Corporate Center, 7700 Edgewater Drive, Oakland, CA 94621, prepared by PJ Chemicals (January 28, 1990)

The subject property was inspected for the presence of asbestos-containing materials (ACMs) on January 20th through 24th, 1990. Tested areas included roofs, tenant improvements (taping and joint compound), fire doors, and 12” floor tiles. Walls in the tenant areas were not sampled due to the amount of samples that would have been needed to determine the presence of ACMs.

ACMs were identified in roofing materials, fire door insulation, and floor tile mastic. No asbestos abatement was performed in connection with this report. Based on the presence of ACMs, AEI recommends the implementation of an Operations and Maintenance (O & M) Plan which stipulates that the repair and maintenance of ACMs should be performed to protect the health and safety of the building occupants.

Phase I Environmental Site Assessment of the Edgewater Park Plaza, 7700 Edgewater Drive, Oakland, California prepared by ENSR Consulting (April 2, 1998)

The subject property is described in this report as approximately 10 acres of land improved by four two-story office buildings located on the east side of Edgewater Drive. The buildings were reportedly constructed in 1973 and comprised 205,000 square feet. Precision Truck School leased approximately one acre of the northeast portion of the parking lot for training purposes.

Based on the ERIIS database report, the subject property was identified as a SLIC site. Files reviewed at the Oakland Fire Department indicated that elevated levels of petroleum hydrocarbons had been identified at the northeastern site boundary in January of 1991. In May 1991, additional soil and groundwater samples were collected at the request of the Alameda County Department of Environmental Health (ACDEH). Environmental Science & Engineering, Inc. (ESE), the consultant engaged to perform the sampling, determined that the source of the contamination was from existing fill. No historical industrial operations were identified at the subject property or adjoining properties. In June, 1991, the ACDEH determined that since there was no evidence to indicate that the contamination resulted from onsite activities, no further action was deemed necessary. Project No. 315265 December 20, 2012 Page 13

Based on the case closure provided by the ACDEH, ENSR concluded that no additional evaluation was warranted.

According to a contact for the subject property interviewed during this assessment, an asbestos abatement was performed at the subject property in 1990 and 1991. Reportedly, asbestos- containing floor tiles and spray-on ceiling material from the first floor bathrooms and the second floor corridor areas was removed in February, 1991, and approximately 6,000 square feet of asbestos-containing floor tile, mastic and particle floorboard was removed in July, 1991. In February, 1993, asbestos flooring mastic found in Suites 360 and 400 in Building B was removed.

A limited screening asbestos survey was performed by ENSR in 1998. A total of 10 samples were collected and analyzed in Building D. Chrysotile asbestos was detected in four samples, collected from damaged resilient sheet flooring under floor tiles in the men’s 2nd-floor restroom; spray-on ceiling texture in the northeast stairwell and hallway; and brown cove base mastic in Room 803. ENSR recommended that the damaged floor tile in the men’s restroom be covered with new flooring or removed, and that an asbestos O&M plan be prepared for the property.

Based on a review of this report, AEI finds the conclusions congruent with the findings of the current report.

Phase I Environmental Site Assessment of 7700 Edgewater Drive, Oakland, California prepared by BA Environmental (November, 2004)

The subject property is described in this report as consisting of two two-story office buildings totaling approximately 205,000 square feet, situated on approximately 10.5 acres of land. The property was reportedly developed from vacant land in 1970.

The historical summary indicates that the property was occupied by undeveloped mudflats, meandering stream channels, and marshland from prior to 1939 until sometime prior to 1958. By 1958, the subject property was vacant land that appeared to be fill material brought onsite, covering the pre-existing wetlands. Since construction, the property had been used as office space by government agencies, non-profit organizations, lawyers, consultants, accountants, corporations, software firms, and various businesses. Precision Truck Driving School had used the parking lot in the northern portion of the site since the late 1990s.

Information reportedly on file with the ACEHD summarized previous soil and groundwater investigations at the subject property. A Phase II soil and groundwater investigation performed by ESE in 1991 summarized the result of 19 borings drilled in the northern parking lot area of the subject property. Soil samples taken at depths ranging from 2.5 to 6.5 feet bgs ranged from 21 to 1,600 parts per million (ppm) total petroleum hydrocarbons as motor oil (TPHmo). A groundwater monitoring well (ESE-1) was installed and sampled at this time. The groundwater sampled measured 0.84 ppm TPHmo; no BTEX (benzene, toluene, ethylbenzene or xylenes) compounds were detected. Further work was requested by the ACEHD to delineate the extent of contamination and determine whether the source was from 7700 Edgewater Drive. Six additional soil samples were obtained from borings taken on the abutting properties in May, 1991. Groundwater samples were analyzed from the previously installed groundwater well and from a boring located approximately 50 feet upgradient from the well. The five offsite soil samples taken at depths of 6 to 7 feet bgs ranged from 1.4 to 21,000 ppm TPHmo. No polychlorinated biphenyls (PCBs) or organochlorine pesticides were detected. A grab Project No. 315265 December 20, 2012 Page 14

groundwater sample taken from approximately 50 feet upgradient of the ESE-1 monitoring well contained 110 ppm TPHmo and 240 ppb Lindane, an organochlorine pesticide. The groundwater sample from ESE-1 had 1.3 ppm TPHmo and no PCBs or organochlorine pesticides.

ESE proposed that the source of the contamination was from the existing fill brought onsite and not from activities associated with 7700 Edgewater Drive. A letter on file with the ACEHD concurred with this suggestion, and stated that there was no guideline policy available from the Regional Water Quality Control Board (RWQCB) regarding contaminated bay fill. No further work was required in the absence of a guideline policy for contaminated fill. The ACEHD noted that if such a policy were developed, additional work may be required.

Based on a review of this report, AEI finds the conclusions congruent with the findings of the current report; however, records reportedly on file with the ACEHD (referred to in the current report as ACDEHS) were not available during AEI’s research. It is possible that the documents reviewed by BA Environmental have since been purged from ACDEHS files.

7.0 SITE INSPECTION AND RECONNAISSANCE

On December 18, 2012, a site reconnaissance of the subject property and adjacent properties was conducted by Brant Rotnem on behalf of AEI in order to obtain information indicating the likelihood of RECs at the subject property and adjacent properties as specified in ASTM Standard Practice E1527-05 §8.4.2, 8.4.3 and 8.4.4. During the onsite reconnaissance, AEI was accompanied by Ms. Brittney Crossland, Building Engineer.

Due to the size of the property, a representative sample of interior spaces was inspected by AEI. Due to the use of the property for administrative/office and educational purposes, this limited inspection method is expected to be adequate for the purposes of this assessment.

7.1 SUBJECT PROPERTY RECONNAISSANCE FINDINGS

Yes No Observation X Hazardous Substances and/or Petroleum Products in Connection with Property Use Aboveground & Underground Hazardous Substance or Petroleum Product Storage X Tanks (ASTs / USTs) Hazardous Substance and Petroleum Product Containers and Unidentified X Containers not in Connection with Property Use X Unidentified Substance Containers X Electrical or Mechanical Equipment Likely to Contain Fluids X Interior Stains or Corrosion X Strong, Pungent or Noxious Odors X Pools of Liquid X Drains, Sumps and Clarifiers X Pits, Ponds and Lagoons X Stained Soil or Pavement X Stressed Vegetation X Solid Waste Disposal or Evidence of Fill Materials X Waste Water Discharges X Wells X Septic Systems X Other

HAZARDOUS SUBSTANCES AND/OR PETROLEUM PRODUCTS IN CONNECTION WITH PROPERTY USE Two janitorial storage areas are located on the subject property. In one of the storage areas, three 55-gallon plastic drums of non-acid disinfectant bathroom cleaner were observed. Based on the use of these materials in connection with standard housekeeping activities and the absence of drains or other potential subsurface conduits in the storage area, the use of these materials is not expected to constitute a significant environmental concern.

ELECTRICAL OR MECHANICAL EQUIPMENT LIKELY TO CONTAIN FLUIDS Toxic polychlorinated biphenyls (PCBs) were commonly used historically in electrical equipment such as transformers, fluorescent lamp ballasts, and capacitors. According to United States EPA regulation 40 CFR, Part 761, there are three categories for classifying such equipment: <50 ppm of PCBs is considered “Non-PCB”; between 50 and 500 ppm is considered “PCB- Project No. 315265 December 20, 2012 Page 16

Contaminated”; and >500 ppm is considered “PCB-Containing”. Pursuant to 15 U.S.C. 2605(e)(2)(A), the manufacture, process, or distribution in commerce or use of any polychlorinated biphenyl in any manner other than in a totally enclosed manner was prohibited after January 1, 1977.

Elevators

The subject property is equipped with two hydraulic elevators. Hydraulic fluid is present within the equipment for this type of machine, and based on the construction age of the buildings, has the potential to contain PCBs. No stains, leaks, or other evidence of a release were present in the vicinity of the elevator equipment, and no drains or other potential subsurface conduits were observed. Based on the good condition of the equipment and small quantities of hydraulic fluid typically present within these systems, the elevator equipment is not expected to constitute a significant environmental concern.

DRAINS, SUMPS AND CLARIFIERS Several storm drains were observed in the parking area of the subject property, and interior drains were observed within the bathroom areas. No hazardous substances or petroleum products were noted in the vicinity of the drains. Based on the use of the drains solely for storm water runoff and housekeeping purposes, the presence of the drains is not expected to represent a significant environmental concern.

7.2 NON-ASTM SERVICES

7.2.1 ASBESTOS-CONTAINING BUILDING MATERIALS OSHA

For buildings constructed prior to 1981, the Code of Federal Regulations (29 CFR 1926.1101 and 29 CFR 1910.1001) define presumed asbestos-containing material (PACM) as 1. Thermal System Insulation (TSI), e.g., boiler insulation, pipe lagging, fireproofing; and 2. Surfacing Materials, e.g., acoustical ceilings. Building owners/employers are responsible for locating the presence and quantity of PACM. Building owners/employers can rebut installed material as PACM by either having an inspection in accordance with Asbestos Hazard Emergency Response Act (AHERA) (40 CFR Part 763, Subpart E) or hiring an accredited inspector to take bulk samples of the suspect material.

Typical materials not covered by the presumptive rule include but are not limited to: floor tiles and adhesives, wallboard systems, siding and roofing. Building materials such as wallboard systems may contain asbestos but unless a building owner/employer has specific knowledge or should have known through the exercise of due diligence that these other materials contain asbestos, the standard does not compel the building owner to sample these materials.

NESHAP

The applicability of the EPA’s National Emission Standards for Hazardous Air Pollutants (NESHAP, 40 CFR Chapter 61, Subpart M) apply to the owner or operator of a facility where an inspection for the presence of asbestos-containing materials (ACM), including Category I (asbestos containing packings, gaskets, resilient floor coverings and asphalt roofing products), and Category II (all remaining types of non-friable asbestos containing material not included in

Project No. 315265 December 20, 2012 Page 17

Category I that when dry, cannot be crumbled, pulverized or reduced to powder by hand pressure), non-friable ACM must occur prior to the commencement of demolition or renovation activities. NESHAP defines ACM as any material or product that contains greater than 1% asbestos. It should be noted that the NESHAP regulation applies to all facilities regardless of construction date, including: 1. Any institutional, commercial, public, industrial, or residential structure, installation, or building; 2. Any ship; and 3. Any active or inactive waste disposal site. This requirement is typically enforced by the EPA or by local air pollution control/air quality management districts.

The information below is for general informational purposes only and does not constitute an asbestos survey. In addition, the information is not intended to comply with federal, state or local regulations in regards to ACM.

As discussed in Section 6.3, the subject property was inspected for the presence of ACMs in 1990. Tested areas included roofs, tenant improvements (taping and joint compound), fire doors, and 12” floor tiles. ACMs were identified in roofing materials, fire door insulation, and floor tile mastic. An asbestos abatement was performed in 1990 and 1991. Asbestos- containing floor tiles and spray-on ceiling material from the first floor bathrooms and the second floor corridor areas was removed in February, 1991, and approximately 6,000 square feet of asbestos-containing floor tile, mastic and particle floorboard was removed in July, 1991. In February, 1993, asbestos flooring mastic found in Suites 360 and 400 in Building B was removed. Additional limited asbestos screening was performed in 1998 in Building D. Chrysotile asbestos was detected in four of ten samples, collected from damaged resilient sheet flooring under floor tiles in the men’s 2nd-floor restroom; spray-on ceiling texture in the northeast stairwell and hallway; and brown cove base mastic in Room 803.

Based on the presence of ACMs, AEI recommends the implementation of an Operations and Maintenance (O & M) Plan which stipulates that the repair and maintenance of ACMs should be performed to protect the health and safety of the building occupants.

7.2.2 LEAD-BASED PAINT Lead-based paint (LBP) is defined as any paint, varnish, stain, or other applied coating that has ≥1 mg/cm2 (5,000 μg/g or 5,000 ppm) or more of lead by federal guidelines; state and local definitions may differ from the federal definitions in amounts ranging from 0.5 mg/cm2 to 2.0 mg/cm2. Section 1017 of the Housing and Urban Development (HUD) Guidelines, Residential Lead-Based Paint Hazard Reduction Act of 1992, otherwise known as “Title X”, defines a LBP hazard is “any condition that causes exposure to lead that would result in adverse human health effects” resulting from lead-contaminated dust, bare, lead-contaminated soil, and/or lead-contaminated paint that is deteriorated or present on accessible, friction, or impact surfaces. Therefore, under Title X, intact lead-based paint on most walls and ceilings would not be considered a “hazard”, although the paint should be maintained and its condition and monitored to ensure that it does not deteriorate and become a hazard. Additionally, Section 1018 of this law directed HUD and EPA to require the disclosure of known information on lead- based paint and lead-based paint hazards before the sale or lease of most housing built before 1978. Most private housing, public housing, federally owned or subsidized housing is affected by this rule.

Lead-containing paint (LCP) is defined as any paint with any detectable amount of lead present in it. It is important to note that LCP may create a lead hazard when being removed. The

Project No. 315265 December 20, 2012 Page 18

condition of these materials must be monitored when they are being disturbed. In the event LCP is subject to abrading, sanding, torching and/or cutting during demolition or renovation activities, there may be regulatory issues that must be addressed.

The information below is for general informational purposes only and does not constitute a lead hazard evaluation. In addition, the information is not intended to comply with federal, state or local regulations in regards to lead-containing paints.

In buildings constructed after 1978, it is unlikely that LBP is present. Structures built prior to 1978 and especially prior to the 1960s should be expected to contain LBP.

Due to the age of the subject property buildings, there is a potential that LBP is present. All observed painted surfaces were in good condition and are not expected to pose a health and safety concern to the occupants of the subject property at this time. Local regulations may apply to lead-based paint in association with building demolition/renovations and worker/occupant protection. Actual material samples would need to be collected or an XRF survey performed in order to determine if LBP is present. It should be noted that construction activities that disturb materials or paints containing any amount of lead may be subject to certain requirements of the OSHA lead standard contained in 29 CFR 1910.1025 and 1926.62.

7.2.3 RADON Radon is a naturally-occurring, odorless, invisible gas. Natural radon levels vary and are closely related to geologic formations. Radon may enter buildings through basement sumps or other openings.

The US EPA has prepared a map to assist National, State, and local organizations to target their resources and to implement radon-resistant building codes. The map divides the country into three Radon Zones, Zone 1 being those areas with the average predicted indoor radon concentration in residential dwellings exceeding the EPA Action limit of 4.0 picoCuries per Liter (pCi/L). It is important to note that the EPA has found homes with elevated levels of radon in all three zones, and the EPA recommends site specific testing in order to determine radon levels at a specific location. However, the map does give a valuable indication of the propensity of radon gas accumulation in structures.

Radon sampling was not requested as part of this assessment. According to the US EPA, the radon zone level for the area is Zone 2, which has a predicted average indoor screening level between 2.0 pCi/L and 4.0 pCi/L, at or below the action level of 4.0 pCi/L set forth by the EPA.

7.2.5 MOLD/INDOOR AIR QUALITY ISSUES Molds are simple, microscopic organisms, which can often be seen in the form of discoloration, frequently green, gray, white, brown or black. When excessive moisture or water accumulates indoors, mold growth will often occur, particularly if the moisture problem remains undiscovered or is not addressed. As such, interior areas of buildings characterized by poor ventilation and high humidity are the most common locations of mold growth. Building materials including drywall, wallpaper, baseboards, wood framing, insulation, and carpeting often play host to such growth. Mold spores primarily cause health problems through the inhalation of mold spores or the toxins they emit when they are present in large numbers. This can occur primarily when there is active mold growth within places where people live or work.

Project No. 315265 December 20, 2012 Page 19

Mold, if present, may or may not visually manifest itself. Neither the individual completing this inspection, nor AEI has any liability for the identification of mold-related concerns except as defined in applicable industry standards. In short, this Phase I ESA should not be construed as a mold survey or inspection.

AEI Consultants observed interior areas of the subject buildings in order to identify the significant presence of mold. AEI did not note obvious visual or olfactory indications of the presence of mold, nor did AEI observe obvious indications of significant water damage. As such, no bulk sampling of suspect surfaces was conducted as part of this assessment and no additional action with respect to mold appears to be warranted at this time.

This activity was not designed to discover all areas which may be affected by mold growth on the subject property. Rather, it is intended to give the client an indication if significant (based on observed areas) mold growth is present at the subject property. Additional areas of mold not observed as part of this limited assessment, possibly in pipe chases, HVAC systems and behind enclosed walls and ceilings, may be present on the subject property.

Project No. 315265 December 20, 2012 Page 20

Hazardous Waste Summary: Waste code: D001 Waste name: IGNITABLE HAZARDOUS WASTES ARE THOSE WASTES WHICH HAVE A FLASHPOINT OF LESS THAN 140 DEGREES FAHRENHEIT AS DETERMINED BY A PENSKY-MARTENS CLOSED CUP FLASH POINT TESTER. ANOTHER METHOD OF DETERMINING THE FLASH POINT OF A WASTE IS TO REVIEW THE MATERIAL SAFETY DATA SHEET, WHICH CAN BE OBTAINED FROM THE MANUFACTURER OR DISTRIBUTOR OF THE MATERIAL. LACQUER THINNER IS AN EXAMPLE OF A COMMONLY USED SOLVENT WHICH WOULD BE CONSIDERED AS IGNITABLE HAZARDOUS WASTE.

Waste code: D002 Waste name: A WASTE WHICH HAS A PH OF LESS THAN 2 OR GREATER THAN 12.5 IS CONSIDERED TO BE A CORROSIVE HAZARDOUS WASTE. SODIUM HYDROXIDE, A CAUSTIC SOLUTION WITH A HIGH PH, IS OFTEN USED BY INDUSTRIES TO CLEAN OR DEGREASE PARTS. HYDROCHLORIC ACID, A SOLUTION WITH A LOW PH, IS USED BY MANY INDUSTRIES TO CLEAN METAL PARTS PRIOR TO PAINTING. WHEN THESE CAUSTIC OR ACID SOLUTIONS BECOME CONTAMINATED AND MUST BE DISPOSED, THE WASTE WOULD BE A CORROSIVE HAZARDOUS WASTE.

Waste code: D003 Waste name: A MATERIAL IS CONSIDERED TO BE A REACTIVE HAZARDOUS WASTE IF IT IS NORMALLY UNSTABLE, REACTS VIOLENTLY WITH WATER, GENERATES TOXIC GASES WHEN EXPOSED TO WATER OR CORROSIVE MATERIALS, OR IF IT IS CAPABLE OF DETONATION OR EXPLOSION WHEN EXPOSED TO HEAT OR A FLAME. ONE EXAMPLE OF SUCH WASTE WOULD BY WASTE GUNPOWDER.

The suspected sources of on-site contamination include releases from underground storage tanks (USTs), gasoline and diesel fuel hydrant systems, and the floor drain waste collection pits formerly located adjacent to Building No. 5. At one time there were 14 petroleum USTs at the site. A comprehensive investigation conducted by Baseline Environmental Consulting (Baseline) in 2000 identified the existence of free-phase petroleum hydrocarbon product in four separate areas of the Site. These four areas are labeled Plumes A through D. Construction of a DPE system was completed in early May 2006. Seven wells within Plume D area (RW-D1 through RW-D5, TBW-5, and RW-1) were connected to the extraction system. On May 22, 2006, the product recovery and groundwater extraction portion of the remediation system (pneumatic pumps) was turned on. On May 14, 2007, the DPE portion of the remediation system was turned on. The second phase included

Approximately 1.1 acres of property are located beneath, 1.3 are on the the south side, and 1.1 acres are onthe north side of the highway. The operations at the Witco site were related to manufacturing of ink, paints, and lacquers from 1947 to 1971. Nineteen underground storage tanks (USTs) were present onsite. The USTs were removed in 1987. The primary constituents identified in the vadose zone are total petroleum hydrocarbons (TPH) and volatile organic compounds (VOCs) centered on the former UST locations. Seventeen soil vapor extraction (SVE) wells (SW-1 through SW-16, and Horz-1) were originally connected to the SVE system. Free product (dark brown to black) has been detected within the perched groundwater zone (found from 30 to 31 feet below ground surface [bgs]) in the areas surrounding the former UST locations. The perched groundwater flow varies from southeast to west at gradients ranging from 0.009 to 0.275. In addition, dissolved TPH, VOCs, and semivolatile organic compounds (SVOCs) are present in the perched groundwater zone. Eighteen wells (SW-1 through SW-18) have been installed onsite. In March 1997, free product (yellow straw color) has been detected within the deep groundwater zone (found from 40 to 42 feet bgs). The deep groundwater flow also varies from southeast to west at gradients ranging from 0.00052 to 0.04. In addition, dissolved VOCs (primarily trichloroethene [TCE]) and dissolved TPH are present within the deep groundwater. Twenty groundwater monitoring wells (MW-1, MW-4, MW-7 through MW-24) have been installed onsite. Three sparge point wells (SP-1 through SP-3) have also been installed at this zone. A SVE system and air sparging system operated at the site from February 1996 through February 1997. The system was shutdown in 1997 due to the detection of yellow free product in the deep zone wells. The existing SVE system was re-started in April 2004 through June 2004 as part of of pilot study related to the free product removal. The SVE system operated, again, from September 2004 to December 2004 until PCE was detected on the influent vapor stream. In 2004, the SVE system operated nine SVE wells including one horizontal welll beneath the Imperial Highway Realignment and three nested, shalllow, deep aquifer sparge wells, and deep-zones wells MW-16 through MW-20. The system was designed to treat vapor and adsorbed, dissolved petroleum product found in the vadose and perched groundwater zones. The systems was also designed to treat dissolved-phase VOCs in the deep groundwater zone. Free product was recovered from February 2003 through April 2005 using absorbents,

Prior to 1989, the Malibu Grand Prix facility maintained two 6,000-gallon underground storage tanks (USTs) containing marine mix gasoline. The two USTs were removed on March 29, 1989 and February 1, 1990, respectively. Free-phase fuel was observed floating on water in the tank excavations during both tank removals. During the tank removal on March 29, 1989, soil samples collected from the tank excavation contained benzene at concentrations ranging from 7.3 to 33 milligrams per kilogram (mg/kg) and total petroleum hydrocarbons as gasoline (TPHg) at concentrations ranging from 50 to 150 mg/kg. During the tank removal on February 1, 1990, soil samples collected from the tank excavation contained benzene at concentrations ranging from 0.07 to 0.31 mg/kg and TPHg at concentrations ranging from 26 to 79 mg/kg. Subsequent site investigations from 1990 to 1996 that included soil and groundwater sampling detected fuel hydrocarbons and oxygenates in soil and groundwater over a wide area beneath the site. Benzene and TPHg were detected in groundwater samples collected from monitoring wells at the site at concentrations up to 2,700 and 20,000 micrograms per liter (a%g/L), respectively. Imported fill material that contains a tar-like substance. The fill material is present throughout the site and appears to have been placed on the site between 1955 and 1975. Known chemicals of concern in the imported fill include polychlorinated biphenyls, phenanthrene, napthalene, pyrene, and lead. ACEH has requested but not recieved additional information to evaluate these environmental concerns.

From September 1959 to March 1992, the site was operated as an auto salvage yard (Otto’s Foreign Auto Salvage) under two successive tenants. Investigations conducted in 1998, 2000 and 2001 found polychlorinated byphenyls (PCBs), tetrachloethylene (PCE), trichloroethylene (TCE), and total petroleum hydrocarbons (TPH) in soil. Groundwater is also contaminated with PCBs, PCE, TCE and vinyl chloride above their respective drinking water standards. The site is adjacent to Aero Quality Plating (01340108) which has similar solvent contamination in soil and groundwater. Comments Date: 04042002 Comments: IS&E Order issued to Union Pacific Railroad.

The pilot study involved injection of cheese whey to stimulate degradation of chlorinated solvents. The groundwater monitoring included testing for a range of parameters which provided an indication of whether degradation of chlorinated solvents was occurring. Breakdown products including trichloroethylene (TCE), dichloroethylene (DCE), and ethenes were observed at appreciable concentrations. Other parameters which were tested included dissolved methane, ethane, chloride, nitrate, sulfate, iron which also provided analytical data which suggested that bioremediation processes were occurring. The weight of the evidence indicated that the site is suitable for remediation through the injection of cheese whey to stimulate degragation of chlorinated compounds in groundwater. The degradation processes may include both bioremedation and chemical reduction of the chlorinated compounds.

PLAN: Reponsible Party: DETAILED SITE EXPENDITURE PLAN Project Revenue Source Company: Not reported Project Revenue Source Addr: Not reported Project Revenue Source City,St,Zip: Not reported Project Revenue Source Desc: In November, 1987, the RPs were found in noncompliance with an imminent and substantial endangerment order issued by the Department. Therefore, Bond funds have been utilized to remediate this site. DHS will undertake appropriate cost recovery activities. This site has not been identified as an NPL site, nor does it appear to be a NPL candidate in the future. Therefore, it appears unlikely that federal funds are a viable source of revenue for remediation of this site. EPA’s Emergency Response Section funded a site stabilization IRM with federal funds. DHS has also funded IRM activities due to limited federal funds and resources. Site Description: Aero Quality Plating electroplated automotive and aircraft parts in baths using copper, chromium, lead, nickel and zinc salts in aqueous solution at the site. Hazardous Waste Desc: Wastes generated onsite included heavy metals and cyanide. Drums stored onsite were open, leaking and corroded. Cyanide and acid solutions were stored onsite in open tanks. Sumps contain toxic sludge. Acids and caustics are incompatible. They are highly corrosive. Acids react with cyanide compounds to produce highly poisonous hydrogen cyanide gas. Threat To Public Health & Env: There is suspected soil contamination and possible ground water contamination. There is a potenital for migration of contamination via surface water runoff to an adjacent stream. A nearby sanitary sewer showed contamination until the water service was disconnected. There was a potential for release of hydrogen cyanide gas into the building and offsite. The concern for a cyanide gas release was mitigated by the removal of cyanide containing liquids and by the segregation of incompatible materials by DHS in July, 1987. Site Activity Status: An interim remedial measure (IRM) was completed by EPA in May, 1987 to stabilize hazardous wastes onsite. DHS has implemented a follow-up IRM to dispose of extermely hazardous waste stabilized by EPA. A second IRM is in progress for removal, disposal and recycling of the remaining 5000 gallons of

Between 1958 and 1987, Aero Quality Plating operated a plating shop on the site. Automotive and aircraft parts were submerged in aqueous solutions containing copper, chromium, lead, nickel, zinc and caustic cyanide during the electroplating process. Aero Quality Plating went bankrupt and abandoned the site and the chemicals from the electroplating operation. Between November 1993 and August 1996, DTSC conducted periodic groundwater monitoring at the site. Work will be coordinated with the adjacent Union Pacific - Oakland Coliseum site (see Envirostor ID 01400015).

DOLSBY HARD CHROME (Continued) 1000183210 Comments: Preliminary Assessment completed

Completed Area Name: PROJECT WIDE Completed Sub Area Name: Not reported Completed Document Type: Site Screening Completed Date: 05/06/1993 Comments: This site is almost entirely covered by a single story metal and cinderblock building which occupies an area of approximately 8000 sq. feet. Mr. Verl Dolsby purchased the business in 1971 and building in 1975. DHC (Dolsby Hard Chrome) site operated as a chrome electroplating facility from 1956 to 1988, during dismantling of the facility in November 1988. Mr. Doslby discovered that chromium wet bath solution had leaked through the concrete lined secondary containment pits. US. EPA has made a site assessment and site does not qualify for listing as a NPL site. Currently Alameda County Dept of Environmental Health (AlCDEH) is the only agency overseeing this site. Soil samples from the bottom of the large pit contamined soluable trivalent and hexavalent chromium as high as 4,000 mg/kg and 5,400 mg/kg, respectively. In addition, it also contained soluble trivalent and hexavalent chromium in groundwater as high as 900 mg/l and 1000 mg/l at a depth of 7 feet. So there has been an observed release at the site. Groundwater is used throughout Alameda County for irrigation, industrial purposes, and domestically for drinking water. Approximately 54 domestic wells serving a population of approximately 140 people within four-miles target distance limit. According to the ALCDEH, the site remains unoccupied and also on file is a Hazardous Material Business Plan Application dated 4/20/88. Up to its closure, Dolsby Hard Chrome had no outstanding issues with the ACDEH. Mr. Dolsby does not have the necessary funds to continue remediation as proposed by EPA consultants. The number of wells used in the Alameda County domestically may be substantially higher due to the wide spread use of groundwater and the lack of an accurate record of all wells in Alameda County. Therefore the site poses a significant threat to public and environmental health. The PEA investigation is required to mitigate the site because the RWQCB did not report a listing for Dolsby Hard Chrome when searched for in its Spills, leaks, investigation and cleanup data base.

Subject: Report Phase 1 Environmental Site Assessment

Dear Ms. McCarthy:

BA Environmental is pleased to submit this Phase I Environmental Site Assessment (ESA) report regarding the above-referenced property to ATC Partners, LLC. The objective of this Phase I ESA was to assess the potential for contamination at the subject property caused by hazardous materials. To accomplish this, a reconnaissance of the subject property and vicinity was performed, available relevant regulatory records were reviewed, and the property history was researched.

The subject property consists of two 2-story office buildings consisting of approximately 205,000 square feet, situated on an approximate 10.5-acre parcel of land. Other improvements include surface asphalt parking and landscaping. The subject property was developed from vacant land in 1970. The review of historical documents revealed that the subject property was occupied by undeveloped mudflats, meandering stream channels, and marshland from prior to 1939 until sometime prior to 1958. By 1958, the subject property was vacant land that appeared to be fill material brought on-site, covering the pre-existing wetlands. The subject property was developed into the existing office buildings and associated asphalt- paved parking lots in 1970 and 1971. The subject site has been used as office space since that time by government agencies, non-profit organizations, lawyers, consultants, accountants, corporations, software firms, and various businesses. Precision Truck Driving School has used the parking lot in the northern portion of the subject property since the late 1990's.

Historically, the adjacent properties were occupied by undeveloped marshland from prior to 1939 until at least 1946. By 1958, the adjoining properties consisted of vacant land that appeared to be fill material. Elmhurst Channel was present to the northwest of the subject property in 1939. The area northwest of the subject property, across Elmhurst Channel, was developed into the existing large commercial buildings after 1993. 7700 Edgewater Drive - Oakland, California November 1, 2004 Page 2

Commercial development in the areas northeast and southeast of the subject property began in the 1960's and was completed by 1982. The area southwest of the subject property, across Edgewater Drive, has consisted of commercial development and vacant land since at least 1982.

BA Environmental performed a visual reconnaissance of the subject property. The subject property, named the Edgewater Park Plaza, is used as office space by various businesses, government agencies, non-profit organizations, lawyers, consultants, accountants, corporations, software firms, and trade schools. The two buildings have been divided into north wings (B and C) and south wings (A and D). Precision Truck Driving School uses the northern portion of the parking lot to teach truck driving techniques to students. No evidence for truck maintenance activities being performed in the Precision Truck Drive School area was observed during the site visit. A large quantity (approximately 150 gallons) of household paint was observed in the paint storage room (4737). In addition, two full and four empty 55-gallon drums of acid free restroom cleaner and small quantities of normal household cleaners were observed in a janitorial closet. No staining was observed on the surfaces beneath containers or paint or cleaning supplies.

No areas of stained soil, stained asphalt or concrete, or distressed or discolored vegetation, were observed on-site during the site reconnaissance.

BA Environmental did not observe issues of environmental concern such as significantly stained pavement or concrete floors, inderground storage tanks (liSTs), aboveground storage tanks (ASTs), floor drains, waste water clarifiers, or significant hazardous materials usage or storage at the subject property.

BA Environmental performed a visual mold survey in accessible areas at the subject property. No evidence of mold growth, or consistently moist environments which may facilitate mold growth, was observed on the property during the site visit.

BA Environmental reviewed previous asbestos surveys and air sampling for asbestos fibers completed at the subject property. Previous asbestos surveys at the subject property indicated that ACMs present on-site include sprayed acoustical, exterior transite boards, 12" by 12" floor tile and mastic, linoleum and mastic in the men's and women's bathrooms, roofing materials, flange gaskets on the heating systems throughout the building, and the interior cores of approximately 40 fire doors covered by wood veneer located throughout the buildings. Air sampling results for airborne asbestos fibers completed in 1990 and 1991 show that the buildings, at the time the samples were taken, were safe for occupancy. Asbestos abatement was completed for sprayed-on acoustical ceiling material in the second floor main corridor and floor tiles located in the bathrooms of the first floor of the building in February of 1991.

motor oil and no BTEX compounds were detected. Further work was requested by the ACDEH to delineate the extent of contamination and determine if the source was from 7700 Edgewater Drive. Six additional soil samples were obtained from borings taken on the abutting properties according to an ESE report dated May 31, 1991. Groundwater samples were analyzed from the previously installed groundwater well and from a boring located approximately 50 feet up-gradient from the groundwater monitoring well. The five off-site soil samples taken at a depth of 6 to 7 feet bgs ranged from 1.4 to 21,000 ppm TPH as motor oil. These soil samples were tested for PCBs and organochlorine pesticides. None were detected. A grab groundwater sample was taken from approximately 50 feet up-gradient of the ESE-1 monitoring well. This water sample contained 110 ppm TPH as motor oil and 240 ppb (parts per billion) Lindane, an organochlorine pesticide. The groundwater sample analyzed from ESE-1 had 1.3 ppm TPH as motor oil. No PCBs or organochlorine pesticides were detected. ESE proposed that the source of the contamination was from the existing fill brought on-site and not from activities associated with 7700 Edgewater Drive. A letter on file at the ACEHD dated June 5, 1991, concurred with this suggestion, concluding: "Currently, there is no guideline policy available from the Regional Quality Control Board regarding contaminated bay fill. While the level of Lindane found poses a concern (drinking water maximum contaminant level is 5 ppb), this was not detected in the groundwater sample from ESE-1. Since the contamination does not appear to be a result of activities at 7700 Edgewater Drive, we will not require The Travelers Company to do further work on their property at this time. Additional work may be required if a guideline policy is developed, or if there is a change in site conditions that could adversely impact human health, the environment, or groundwater quality. This letter does not preclude any other environmental agency from requiring additional investigation."

BA Environmental reviewed selected government environmental databases. The subject property was listed on the HAZNET database. The Edgewater Park Plaza and the San Francisco Girl Scout Council (7700 Edgewater Drive) were listed on the HAZNET database. According to the HAZNET database, waste oil and waste hydrocarbon solvents have been manifested from the subject property. These hazardous wastes were removed from the subject property and disposed of by a hazardous waste iecycler. Infomiation obtained during the site visit indicated that hazardous waste is no longer generated at the subject property. No violations, spills, or releases were listed in the database for the subject property address. The closest listed facility is located immediately northeast (up- gradient) of the subject property. This facility (Goodyear Tire and Rubber Company, 7727 Oakport Street) was listed on LUST, Cortese and CA FIB UST databases. At the time of the site visit, this adjoining property was vacant and an existing sign indicated that it was most recently occupied by a Volvo automobile dealership. According to the LUST database, a diesel fuel release from an underground tank was found to have impacted the soil only. The impacted soil was excavated and removed from this adjoining property and the case was closed on August 1, 1994. Based on this LUST site's "Case Closed" status and that the release was limited to the soil only, it is the opinion of BA Environmental that there is a low potential for environmental impact to the subject property from this adjoining LUST site. Based on the locations, distances and statuses of the remaining facilities identified in the database, there is a low potential for environmental impact due to off-site sources.

BA Environmental has performed a Phase I ESA, in conformance with the scope and limitations of ASTM Practice E 1527-00, of the property located at 7700 Edgewater 7700 Edgewater Drive - Oakland, California November 1, 2004 Page 4

Drive, in the City of Oakland, California. Any exceptions to, or deletions from, this practice are described in the Introduction section of this report.

This assessment has revealed the following historical recognized environmental conditions in connection with the subject property: The soil and groundwater beneath the subject property has been impacted by hydrocarbons (motor oil). The source of the contaminated soil appears to be fill material brought on-site in the 1940's and 1950's. A letter on file from the ACEHD dated June 5, 1991, indicated that no regulatory guidelines exist regarding contaminated bay fill and since the contamination does not appear to be a result of activities at 7700 Edgewater Drive, no further action on the subject property was required at that time.

This assessment has revealed no recognized environmental conditions in connection with the subject property, except the following: ACMs exist inside of the subject buildings; and An inactive groundwater monitoring well from a previous investigation exists on the northern portion of the subject property.

BA Environmental recommends the following: Continue the existing asbestos Operations and Management Program, informing contractors and tenants about the ACMs identified within the buildings. If confirmed ACMs are scheduled for renovation or demolition activities, they should be removed by a licensed asbestos abatement contractor; and Abandon the monitoring well located on the northern portion of the subject property under the supervision of the ACEHD, in accordance with all state and local regulations.

104228 7700 Edgewater Dr.. Oakland PHASE I ENVIRONMENTAL SITE ASSESSMENT 7700 Edgewater Drive Oakland, California

INTRODUCTION

BA Environmental (a Division of Building Analytics) is pleased to submit this Phase I Environmental Site Assessment (ESA) report to ATC Partners, LLC. This report is regarding the two office buildings located at 7700 Edgewater Drive, in the City of Oakland, California.

This report was prepared in accordance with the BA Environmental Proposal and Contract dated October 18, 2004.

The purpose of the ESA is to identify, to the extent feasible, recognized environmental conditions, which can be defined as, "The presence or likely presence of any hazardous substance or petroleum products under conditions that indicate an existing release, a past release or a material threat of any hazardous substances or petroleum products."

This Phase I ESA meets the general requirements of the American Society for Testing and Materials (ASTM) Standard Practice for Environmental Site Assessments: E 1527- 00. The ASTM standard practice defines good commercial and customary practice for conducting ESAs using reasonable inquiry. The scope of services for this Phase I ESA consisted of several tasks, including: A reconnaissance of the site and its vicinity; Interviews with current owners and occupants of the subject property, and personnel at local government agencies; A compilation of the property history, including the review of previous environmental reports regarding the subject property (if available); An agency list search of facilities with recorded environmental issues located within the radii required by ASTM; and A summary of our findings, conclusions and recommendations.

Additional services that were provided include: A visual survey and review of map of designated wetlands; A visual mold survey; A visual asbestos survey of suspect asbestos-containing materials (ACMs); and A review of a survey and map of radon zones.

As per ASTM Practice E 1527-00, there are no deviations from, or deletions of the general requirements of this standard practice contained in this report.

A Phase I ESA is a non-intrusive examination. As such, it is not a full and complete assessment of all environmental conditions. Adverse conditions may exist that could not

1 104228 7700 Edgevaier Dr.. Oakland be discovered by such an assessment. BA Environmental has made every reasonable effort to discover and interpret the information and current conditions regarding the site within the time available. We will recommend prudent additional investigations, if deemed necessary.

This report must not be regarded as a guarantee that no further contamination exists beyond that which may have been detected within the building or beneath the property. If additional relevant information about the property is brought to our attention, the conclusions and recommendations contained in the report may not be valid.

This assessment relied upon information obtained from the site reconnaissance and from relevant regulatory agencies. BA Environmental believes that the information contained herein is reliable. However, BA Environmental cannot guarantee the accuracy of information provided by others.

SITE LOCATION

The subject property is located at 7700 Edgewater Drive, on the eastern corner of the intersection of Edgewater Drive and the Elmhurst Channel, in the City of Oakland, California. The subject property may be reached from Interstate 880, exit Hegenberger Road and proceed to the southwest for approximately 0.25 miles to Edgewater Drive. Turn northwest (right) on Edgewater Drive and proceed approximately 0.5 miles to the subject property. Primary vehicular access is from Edgewater Drive to the southwest of the subject property.

The subject property consists of two 2-story office buildings consisting of approximately , 205,000 square feet, which are situated on an approximate 10.5-acre parcel of land. Other improvements include surface asphalt parking and landscaping. The subject property was developed from vacant land in 1970.

104228 7700 Edgrrvarrr Dr. Orkla,rd Oakland-Alameda County Coliseum Complex is located approximately 0.5 miles north of the subject property. The Metropolitan Oakland International Airport is located approximately 1.0 mile southwest of the subject property. The subject site was depicted as vacant land in 1959 and occupied by the existing office buildings in 1980. The adjoining properties were depicted as vacant land in the late 1950's and consisted of vacant land and large commercial buildings by 1980. The 1993 topographic map indicated that the subject property, adjoining properties, and surrounding area were developed at this time.

The subject site and the surrounding area are flat land with a gentle slope toward Elmhurst Channel to the northwest. The elevation at the subject site is approximately five feet above mean sea level (msl).

Elmhurst Channel, a straightened flood control channel, is located adjacent to the northwest of the subject property. A straightened flood control channel is located approximately 0.125 miles southwest of the subject property. Airport Channel, consisting of marshland and mudflats, is located approximately 0.25 miles west of the subject property. These channels flow into San Leandro Bay, which is a portion of San Francisco Bay. No other major bodies of surface water (i.e., oceans, lakes, rivers, streams, etc.) are located within a one-mile radius of the site.

A review of the topographic maps and a reconnaissance of the surrounding area indicate that no active oil wells are located within a 0.25-mile radius of the subject site. 2

GEOLOGY AND HYDROGEOLOGY

The City of Oakland is located in the San Francisco Bay region, which is underlain by some of the most complex and active geology in the world. The San Francisco Bay region geology ranges from iron- and magnesium-rich rocks formed deep in the interior of our planet to sand and gravel recently deposited by streams and rivers. All of these rocks are constantly being bent and tilted by the forces that also drive the San Andreas, Hayward, and other faults. The same forces that cause earthquakes have shaped the landscape that makes this region unique: the hills, the valleys, and the Bay itself That landscape is still being formed, the Earth's forces driving hills and mountains up, rain and gravity dragging them back down, sometimes in massive landslides or dangerous flows of mud and debris. The subject site is underlain by approximately 10 to 15 feet of fill material that varies in composition from sand to sandy clay. The fill material is underlain by approximately 40 feet of silty clay Bay Mud. 3

Information obtained from the EDR Geocheck report indicated that groundwater depth and flow direction vary greatly in the vicinity of the subject property. A groundwater investigation conducted at the northwestern portion of the site revealed that first groundwater was encountered at approximately four feet below ground surface (bgs) in May of 1991, and groundwater flow direction was determined to be towards the west. A total dissolved solids test of a groundwater sample collected during the investigation indicated that the groundwater is brackish (a mixture of salt and fresh water) and unfit for human consumption. 4

3 104228 7700 Edgewaxer Dr. Oakland HISTORICAL REVIEW

As part of the historical review, BA Environmental reviewed available historical aerial photographs, topographic maps, city directories, and building records. Aerial photographs were available for the subject property for the years 1939, 1946, 1958, 1965, 1982, and 1993. Sanborn fire insurance map coverage does not exist for the subject property. 5,6,7,8

History of Subject Property

The subject property was occupied by undeveloped mudflats, meandering stream channels, and marshland from prior to 1939 until sometime prior to 1958. By 1958, the subject property was vacant land that appeared to be fill material brought on-site, covering the pre-existing wetlands. The subject property was developed into the existing office buildings and associated asphalt-paved parking lots in 1970 and 1971. The subject site has been used as office space since that time by government agencies, non-profit organizations, lawyers, consultants, accountants, corporations, software firms, and various businesses. Precision Truck Driving School has used the parking lot in the northern portion of the subject property since the late 1990's. A list of former tenants is provided in Appendix A.

History of Adjacent Properties

The adjacent properties were occupied by undeveloped marshland from prior to 1939 until at least 1946. By 1958, the adjoining properties consisted of vacant land that appeared to be fill material. Elmhurst Channel was present to the northwest of the subject property in 1939. The area northwest of the subject property, across Elmhurst Channel, was developed into the existing large commercial buildings after 1993. Commercial development in the areas northeast and southeast of the subject property began in the 1960's and was completed by 1982. The area southwest of the subject property, across Edgewater Drive, has consisted of commercial development and vacant land since at least 1982.

Review of Previous Environmental Reports

BA Environmental reviewed previous Phase I and Phase II Environmental Assessments for the subject property:

5 EDR, Aerial Photography Print Service, Inquiry No. 12947 10-5, October 28, 2004. 6 EDR, City Directories Abstract, Inquiry No. 1294710-7, October 25, 2004. 7 Building Department, agency visit October 26, 2004 8 EDR, Sanbom® Map Report, Inquiry No. 1294710.3s, October 25, 2004.

4 104228 - 7700 Edgewater Dr Oakland local, state, and federal environmental records. The CETC investigation found that the subject site has not been utilized to dispose, produce, manufacture or store large quantities of hazardous or toxic materials. Approximately 15 five-gallon containers of hydraulic oil were observed stacked behind the boiler room. CETC recommended that these containers be properly stored. Approximately 30 gallons of CHEMTEX B-262 boiler water treatment was observed in the boiler room. Three 55-gallon drums were observed in the rear parking lot behind a trash dumpster. Two of the drums were generically marked as Industrial Water Treatment and one was generically marked as Water Softener. CETC recommended that the contents of the three 55-gallon drums be analyzed to determine their content and be removed accordingly and properly disposed. CETC also recommended that the discolored soil around the three drums be sampled and tested depending on the content of the drums.

TransWorld Consortium, Inc. (TCI), Hazardous Materials Testing Report, The Edgewater Property, 7700 Edgewater Drive, January 31, 1991. TO reported on their soil testing activities conducted on the subject property as recommended by CETC. TO observed on January 21, 1991, an approximately 15 square foot (3' x 5') petrochemical stain on the asphalt paved area around the trash compactor behind the buildings on the northern portion of the subject property. The stain was covered with a thin layer of soil, apparently to absorb the agent which had spilled. There was no evidence that that the spill had flowed into the soil planter area adjacent to the asphalt parking lot. Four soil samples were taken at two locations and analyzed for hydrocarbons using the DHS LTJFT method. Three samples were taken in the stain area, one at the surface from the saturated soils which covered the stained area (Sample #1), one immediately below the strata of asphalt-permeated aggregate (Sample #2), and one 12" below the top of the underlying layer of native soil (Sample #3). Sample #1 revealed the presence of total petroleum hydrocarbons (TPH) as motor oil at a concentration of 170,000 parts per million (ppm), Sample #2 revealed 53,000 ppm TPH as motor oil, and Sample #3 revealed 20,000 ppm TPH as motor oil. Sample 94, taken in a planter approximately 20 feet away from the stain adjacent to the dumpster, revealed the presence of 13,000 ppm TPH as motor oil. TCI recommended that further testing be conducted at greater depths to define the extent and depth to which the hydrocarbon plume may have spread.

TransWorld Consortium, Inc. (TCI), Results of Preliminary Soil and Groundwater Investigation, 7700 Edgewater, March 4, 1991. TO collected a total of 10 soil samples at various distances, up to 50 feet away from the original stain. A number of water samples were taken at or near the water table approximately 4 to 6 feet below grade. Analysis of the water samples showed that motor oil contamination was present across much of the eastern portion of the site. However, a water sample under the surface stain was virtually contaminant free (21 ppm), while a soil sample located further away within the saturated zone below the water table was contaminated at a higher level. TO hypothesized that the stain is a minor localized problem and the source of the contaminated soil and groundwater is widespread and might be from an off-site source. They concluded that the pollution was widespread and the size and severity of the contaminant plume was difficult to predict. TO recommended a more extensive soil and groundwater testing program.

TransWorld Consortium, Inc. (TCI), Phase II Environmental Site Assessment, The Edgewater Property, 7700 Edgewater, March 13, 1991. TO collected a total of 12 additional soil samples from the groundwater table interface (3 to 6 feet below grade) along the eastern, northern, and southern property boundaries. Very low levels of motor oil contamination (typically between 20 to 50 ppm) were detected along the northern and southern boundaries as well as a portion of the lot near the buildings. Based on the results of their investigation, TCI speculated that the oil in the groundwater may be a

104228 7700 Edgewater Dr., Oakland regional problem in this area of Oakland, that contamination does not appear to be moving off-site from the subject property, and since contaminant levels were relatively higher (110 to 550 ppm) at several locations on the extreme eastern property boundary, it is likely that the adjacent industrial property to the east of the subject site may have contributed to the motor oil contamination.

Environmental Science & Engineering, Inc. (ESE), Report of Findings for Site Assessment and Well Installation at Edgewater Corporate Center, 7700 Edgewater Drive, April 11, 1991. ESE performed a site assessment on the subject property to obtain information concerning past use of the subject property and possible sources of the petroleum hydrocarbons in the soil and groundwater found in previous investigations. A groundwater monitoring well was installed on the subject property to obtain a representative groundwater sample from beneath the site. A soil sample was collected from 2.5 feet below grade during the drilling of the monitoring well and analyzed for extractable hydrocarbons, Polychlorinated Biphenyls (PCBs), Oil and Grease, Volatile Organics, and several metals. The only organics detected were 630 ppm as Oil and Grease and 720 ppm TPH as motor oil. The metals concentrations found were all below California hazardous waste designations and were interpreted as representative of soil background concentrations. The PCB Aroclor-1260 was detected at a concentration of 0.05 ppm which was below the California hazardous waste designation of 5 ppm. The groundwater sample was analyzed for Oil and Grease, TPH, and Volatile Organics. None of these constituents were detected except 840 ug!l (0.84 mg/l) TPH as motor oil. The groundwater sample was also analyzed for Total Dissolved Solids, which indicated that that the water was brackish and not likely to be useful for drinking water. ESE's historical research found no evidence of the existence of a substantial source of heavy hydrocarbons at the subject property or adjacent properties. They found that the area was built with imported fill, and the source of this fill is generally unknown. As the Oakland waterfront has been used for industrial activities for over a hundred years, it was ESE's opinion that this area may have been filled with soil containing hydrocarbons imported from some other nearby industrial area. Further evidence for hydrocarbons found in the regional fill material was obtained from underground storage tank investigations in the area that have found TPH as oil and grease in soil not associated with the contents of the leaking tanks. ESE speculated that the ubiquitous presence of low levels of TPH as motor oil in soil samples may be due to the presence of organic matter in the soil found around the bay. However, the presence of PCB in one soil sample indicates that some of the contamination is from a man-made source.

Environmental Science & Engineering, Inc. (ESE), Report of Findings from Additional Soil and Groundwater Sampling near the Edgewater Corporate Center, 7700 Edgewater Drive, May 31, 1991. ESE performed additional site assessment at the subject property as requested by the Alameda County Department of Environmental Health (ACDEH). ESE drilled six additional borings to satisfy the ACDEH request. None of the soil samples collected appeared oily or showed evidence of petroleum hydrocarbon contamination. Analytical results indicated that TPH as motor oil was detected in all of the soil and groundwater samples ranging in concentrations from 1.3 to 21,000 ppm. A groundwater sample collected approximately 50 feet up-gradient from the previously installed monitoring well (ESE-1) contained 110 ppm TPH as motor oil, and 240 parts per billion (ppb) Lindane, a relatively common and persistent pesticide. The groundwater sample from ESE-1 contained 1.3 ppm TPH as motor oil and no detectable concentrations of organochiorine pesticides and PCBs. ESE concluded that whatever the source, the widespread presence of TPH in the soil beneath the site precludes practical remediation of the soil. In addition, heavier, nonvolatile hydrocarbons such as those found at this site generally do not migrate rapidly through silty and clayey soil, are not soluble in groundwater, and do not present a serious

6 104228 - 7700 Edgewater Dr. Oakland environmental threat. ESE recommended no further action on the site and that closure be granted by the ACDEH and the Regional Water Quality Control Board.

Letter from Cynthia Chapman, Hazardous Materials Specialists, Alameda County Health Care Services Agency (ACDEH), to Mr. Steve Rothert of The Travelers, Regarding the Site Assessment at 7700 Edgewater Drive, Oakland, dated June 5, 1991. This letter summarized the results of previous soil and groundwater investigations undertaken at the subject property. A copy of this letter is provided in Appendix B. Ms. Chapman concurred with the suggestion of ESE that the source of the contamination was from the existing fill brought on-site and not from activities associated with 7700 Edgewater Drive. The letter stated that "Currently, there is no guideline policy available from the Regional Quality Control Board regarding contaminated bay fill. While the level of Lindane found poses a concern (drinking water maximum contaminant level is 5 ppb), this was not detected in the groundwater sample from ESE-l. Since the contamination does not appear to be a result of activities at 7700 Edgewater Drive, we will not require The Travelers Company to do further work on their property at this time. Additional work may be required if a guideline policy is developed, or if there is a change in site conditions that could adversely impact human health, the environment, or groundwater quality. This letter does not preclude any other environmental agency from requiring additional investigation."

ENSR Consulting, Engineering and Remediation (ENSR), Phase I Environmental Site Assessment (ESA), Edgewater Park Plaza, 7700 Edgewater Drive, Oakland, California, for Criimi Mae, Inc., Document Number 2048-028-100, dated April 2, 1998. ENSR performed a Phase I ESA for the subject property which included a site reconnaissance, property history research, review of an ER-US database report, and local regulatory agency file reviews, a limited asbestos survey, and a limited lead-based paint survey. No off-site issues of environmental concern were identified during the ENSR ESA. No environmental regulatory compliance problems or underground storage tanks were identified during the site reconnaissance. According to ENSR's historical review, the subject site was marshland filled with soil brought in from off-site prior to the development of the subject property in the early 1970's. During the ENSR investigation, evidence was found indicating the presence of hydrocarbon-contaminated soil at the northeast boundary of the subject property. Soil and groundwater samples were taken in this area at the request of the Alameda County Department of Environmental Health (ACDEH) by Environmental Science and Engineering (ESE), in January and May of 1991. According to the ENSR report, ESE determined that the source of the contamination was the existing fill brought onto the subject property, and that no industrial activities on-site or off-site have occurred that would have caused the detected contaminants. In June of 1991, the ACDEH determined that because there was no evidence to indicate that the hydrocarbon contaminated soil was a result of on-site activities, no further action was deemed necessary at the subject site. ENSR concluded, "The on-site contamination will not materially impact the use of the Subject Property."

SITE RECONNAISSANCE AND IMPROVEMENTS

On October 26, 2004, BA Environmental performed a visual reconnaissance of the subject site located at 7700 Edgewater Drive, in the City of Oakland, California. Mr. Greg Hargieroad of BA Environmental conducted the site reconnaissance escorted by Armando Rivera, Building Engineer. Mr. Rivera was unaware of any environmental concerns associated with the subject property.

104228 7700 Edgrrv1cr Dr., Oakland The subject property consists of two 2-story office buildings consisting of approximately 205,000 square feet, which are situated on an approximate 10.5-acre parcel of land. Other improvements include surface asphalt parking and landscaping. The subject property was developed from vacant land in 1970.

The exterior building walls consist of wood-framed construction with an exterior stucco finish and cedar siding. The interior finishes in the common areas and in the tenant spaces consist of commercial grade carpeting, painted gypsum board walls and an acoustical ceiling system. The ceilings consist of painted drywall, spray-on acoustical material, or 2' by 4' and 2' by 2' suspended acoustical ceiling panels. The floors are bare concrete or covered with 12" by 12" floor tile, ceramic tile and carpet. The roofing system consists a multi-ply roofing membrane with gravel surfacing.

The heating, ventilating and air conditioning (HVAC) systems consist of package units and heat pumps located on the roof and within a boiler and chiller room located between the two buildings. All of the HVAC units were electric and/or natural gas operated. Two 5-gallon containers of nitrite borate corrosion inhibitor were observed on the concrete pad of the boiler and chiller room.

The subject property, named the Edgewater Park Plaza, is used as office space by various businesses, government agencies, non-profit organizations, lawyers, consultants, accountants, corporations, software firms, and trade schools. The two buildings have been divided into north wings (B and C) and south wings (A and D). Precision Truck Driving School uses the northern portion of the parking lot to teach truck-driving techniques to students. No evidence for truck maintenance activities being performed in the Precision Truck Drive School area was observed during the site visit. A large quantity (approximately 150 gallons) of household paint was observed in the paint storage room (9737). In addition, two full and four empty 55-gallon drums of acid free restroom cleaner and small quantities of normal household cleaners were observed in a janitorial closet. No staining was observed on the surfaces beneath containers or paint or cleaning supplies. See Appendix A for current and previous tenants of the subject property.

Storm water that collects on the roof is directed into roof drains and storm water that collects on the asphalt-paved surfaces is directed into storm drains. From there it is discharged into the city-owned flood control system (Elmhurst Channel).

Trash dumpsters were observed in several areas of the subject property. These containers appeared to contain non-hazardous paper and plastic waste. No significant staining was observed on the concrete and asphalt surfaces beneath the trash containers.

No areas of exposed or stained soil, stained asphalt or concrete, or distressed or discolored vegetation, were observed on-site during the site reconnaissance.

BA Environmental did not observe issues of environmental concern such as significantly stained pavement or concrete floors, underground storage tanks (LISTs), aboveground storage tanks (ASTs), floor drains, wastewater clarifiers, or significant hazardous materials usage or storage at the subject property.

Pits, Ponds and Lagoons

Pits, ponds and lagoons are often associated with the disposal of solid and liquid wastes, which may include hazardous materials. According to ASTM Standard E 1527-00, pits,

104228 7700 Edgewater Dr Oakland ponds and lagoons are "man-made or natural depressions in the ground surface that are likely to hold liquid or sludge containing hazardous substances or petroleum products." Information obtained from the assessment indicated that pits, ponds and lagoons do not currently exist on the subject site. Based on the review of historical records of the subject site (aerial photographs), it is unlikely that pits, ponds or lagoons have existed at the site in the past.

Septic Tanks and Cesspools

Septic tanks and cesspools are often associated with the disposal of wastewater from structures that are not served by public sewer systems. Septic tanks and cesspools may be associated with hazardous materials, if such materials have been inappropriately disposed of in the past via sinks. Information obtained from the subject site reconnaissance indicated that septic tanks and cesspools do not currently exist on the subject site.

Wells, Cisterns and Sumps

No evidence of the presence of wells, sumps, cisterns, standpipes or well heads was observed at the subject site, with the exception of a capped monitoring well located on the northeast portion of the subject property. This monitoring well was installed on the subject property in 1991 as part of Phase II Environmental Assessment activities performed at the subject property in the early 1990's. Based on visual observations made during the site reconnaissance, this well does not appear to have been destroyed.

Polychlorinated Biphenyls (PCBs)

Federal regulations put into effect following the Toxic Substance Control Act (TSCA) require that electrical transformers be labeled to identify their PCB content. The manufacture and distribution of PCBs was banned in 1979. One pad-mounted transformer was observed on site, adjacent to the boiler room. The transformer is owned and operated by Pacific Gas and Electric (PG&E). No stains were observed adjacent to this transformer during the site reconnaissance. According to a previous environmental assessment of the subject property, the on-site transformer does not contain PCBs. PG&E is responsible for all maintenance and environmental issues concerning this transformer.

Hydraulic elevators are located in the buildings. The elevator hydraulic equipment appeared in good condition on the day of the site reconnaissance. The elevators are inspected monthly and maintained by Trans Bay Elevator Company. No evidence of leakage was observed on the concrete floor of the elevator equipment rooms during the site visit.

Fluorescent lighting was observed throughout the buildings. Fluorescent ballasts containing PCBs have not been manufactured since the late 1970's, and have a general life expectancy of 15 years. None of the fluorescent fixtures were inspected up close; however, at a distance the fluorescent fixtures appeared to be of recent manufacture. Based on the age of the buildings, constructed in 1970, it is unlikely that the light ballasts contain PCBs. BA Environmental did not observe other equipment on-site likely to contain PCBs.

9 104228 7700 Edgewaier Dr.. Oakland BA Environmental reviewed previous asbestos reports prepared for the subject property:

Certified Engineering & Testing Company (CETC), Environmental Site Assessment (ESA) and Supplemental Asbestos Survey, 7700 Edgewater Drive, Oakland, California, for Traveler's Real Estate Investment Corporation, Certified Project No: S90019, dated February 15, 1989. The CETC asbestos survey consisted of eighteen bulk samples taken of suspect ACMs including floor tile, roofing tar, floor linoleum, ceiling tile, stucco, duct joint tape, piping and boiler insulation, roofing tar paper, and textured spray-on ceiling material. Three samples tested positive for asbestos (2% Chrysotile): roofing tar, pipe sealant on the roof, and the mastic on the floor tile on the second floor (room 200). CETC also identified "transite" on the walls of the cooling tower as an ACM. CETC recommended that in the event of any planned disturbance or demolition of these materials, a licensed contractor be consulted and suspect materials be sampled.

PJ Chemicals, An Asbestos Consulting Firm (PJC), Results of Asbestos Survey January 20-24, 1990, Edgewater Corporate Center, 7700 Edgewater Drive, Oakland, California, for Tishman West Companies, dated January 28, 1990. The PJC survey collected and analyzed approximately 70 samples, finding asbestos in the following materials: Spray-on acoustic material on the ceilings, transite board located on the exterior of buildings, white floor tile and mastic, the paper backing on all linoleum in bathrooms, mastic under 12" by 12" floor tile and linoleum, all fire doors, bottom layer of roofing paper, mastic around vents and other protruding objects of roofs, three layers of roofing materials on building 100-400, flange gaskets in HVAC systems, and the transite walls of the cooling tower and black baffles in the interior of the tower.

PJ Chemicals, An Asbestos Consulting Firm (PJC), Requirements for Asbestos Operations and Maintenance Program (O&M Program), Edgewater Corporate Center, 7700 Edgewater Drive, Oakland, California, for Tishman West Companies, dated March 23, 1990. The PJC O&M Program placed a priority level on several homogeneous areas that contain ACMs and listed the necessary procedures needed to manage the ACMs in place.

PJ Chemicals, An Asbestos Consulting Firm (PJC), Results of Air Monitoring on May 23 and 24, 1990, Edgewater Corporate Center, 7700 Edgewater Drive, Oakland, California, for Tishman West Companies, dated July 11, 1990. Four air monitoring samples were taken in two evenings in late May of 1990. Three of the air samples showed an asbestos structure count of <20 total per square millimeter, while one sample measured 39 total per square millimeter. The letter report concluded that these results show that the buildings, at the time the samples were taken, were safe for occupancy.

EnviroGroup, Industrial Hygiene Services (EG), Industrial Hygiene Monitoring at 7700 Edgewater Drive, Oakland, California, dated March 19, 1991. EG conducted air sampling for asbestos fibers at the subject property on February 16, 1991. The air sampling was done during asbestos abatement activities of sprayed-on acoustical ceiling material in the second floor main corridor and floor tiles located in the bathrooms of the first floor of the building. Seven air samples taken during removal of the ACMs measured below the current industry standard for acceptable levels of airborne asbestos fibers following an abatement project in occupied buildings.

11 104228 - 7700 Edgewater Or., Oakland Letter of "Asbestos Notification" from Debra Todd, Property Manager of the Edgewater Park Plaza, to All Edgewater Park Plaza Vendors, dated October 5, 1993. This letter, sent to 13 vendors at the subject property, provided a list of all ACMs identified in the buildings. The letter requests that the property manager be informed of any alterations of construction activities which may disturb these materials, causing asbestos fibers of become airborne. The letter states that "only persons authorized and properly trained should perform any work which may disturb asbestos materials."

Visual Mold Survey

Radon Gas Survey

Radon is a radioactive gas that occurs naturally in the environment and cannot be seen, smelled or tasted. The human health effect associated with exposure to elevated levels of radon is an increased risk of developing lung cancer. The US Environmental Protection Agency (EPA) and the US Center for Disease Control are concerned about the increased risk of lung cancer developing in individuals exposed to above average levels of radon in their homes or offices. In order to address these concerns, the US EPA conducted a radon survey and presented the results for various counties in 1993.

The EPA's map of Radon Zones assigns each of the 3,141 counties in the United States to one of three zones. The zone designations were determined by assessing five factors that are known to be important indicators of radon potential: indoor radon measurements, geology, aerial radioactivity surveys, soil parameters and foundation types. The subject site falls within the designation of Zone 2. Zone 2 counties have a predicted average indoor radon screening level of greater than or equal to 2 picocuries per liter (pCi/l) or less than or equal to 4 pCi/L. Based on the results of the survey, the subject site appears to fall below the recommended EPA Action Level of 4.0 pCi/l. Based upon the study results, there is a low potential that radon is a concern for the subject site.

ADJACENT LAND USE

During the reconnaissance of the surrounding area within a 0.25-mile radius, BA Environmental observed that the subject site is located in an area of commercial and light industrial land use.

The subject property is bordered to the northeast by several large commercial buildings occupied by Wombat Keyboards (7711 Oakport Street), TAMAW District 190 union headquarters (7717 Oakport Street), the Cash Register Company (7719 Oakport Street), Nisei Plastics (77121 Oakport Street), Magic Apparel (7723 Oakport Street), a vacant Volvo Dealership (7725 or 7727 Oakport Street), and Italian Ceramic Tile (7729 Oakport Street). The subject property is bordered to the southeast by commercial buildings occupied by S&S Trucking and Peak Engineering (477 Roland Way), Tima Power Systems (475 Roland Way), CPC Technology (473 Roland Way), Fugro West (469

9 EPA Map of Radon Zones, 1993.

12 104228 7700 Edgewater Dr., Oakland Roland Way), Milligan Spika Company (463 Roland Way), California Equipment (485 Roland Way), and RJR Polymers (7750 Edgewater Drive). The area to the southwest of the subject property, across Edgewater Drive, is occupied by office buildings occupied by the Alameda County Social Services Agency (7751 Edgewater Drive) and various tenants (7717 Edgewater Drive), a vacant lot, and Parlee Lane. Elmhurst Channel borders the subject property to the northwest followed by a large building occupied by Rainin Instrument Inc. (7500 Edgewater Drive) and a multi-story office building occupied by IKON Office Solutions.

Wetlands and Flood Plains

During the site reconnaissance and drive-by survey of the surrounding area, BA Environmental observed that the subject property is located in an area where wetlands are abundant. According to the Environmental Data Resources, Inc. (EDR) report, over a dozen wetlands are located within a one-mile radius of the subject site as mapped by the National Wetlands Inventory (1994). Many of these wetlands are associated with mudflats and marshland located in San Leandro Bay, located approximately 0.5 miles west of the subject property. The closest wetland mapped is Elmhurst Channel, located adjacent to the northwest of the subject site. The banks of this straightened flood control channel, which was full at the time of the site visit due to recent rains, were lined with riparian vegetation. According to information provided in the EDR report, the subject site is located within a 500-year flood zone and adjacent to a 100-year flood zone associated with Elmhurst Channel per the Federal Emergency Management Agency (FEMA).'

AGENCY CONTACTS

Alameda County Department of Environmental Health (ACDEH) and City of Oakland Fire Department (OFD) BA Environmental contacted the ACDEH and OFD regarding USTs, leaking USTs (LUSTs), hazardous materials storage and hazardous materials permits for the subject property. According to the ACDEH and OFD, there are no active hazardous materials files for the subject property.

A letter on file at these agencies dated June 5, 1991, from Cynthia Chapman, Hazardous Materials Specialist, to Mr. Steve Rothert of The Travelers, summarized the results of previous soil and groundwater investigations undertaken at the subject property. A copy of this letter is provided in the Appendix B. A Phase II soil and groundwater investigation report by Environmental Science and Engineering (ESE) dated April 11, 1991, summarized the results of 19 borings drilled in the northern parking lot area of the subject property. Soil samples taken at depths ranging from 2.5 to 6.5 feet bgs ranged from 21 to 1,600 parts per million pm) TPH as motor oil. A groundwater monitoring well (ESE-1) was installed and sampled at this time. The groundwater sample measured 0.84 ppm TPH as motor oil and no BTEX compounds were detected. Further work was requested by the ACDEH to delineate the extent of contamination and determine if the source was from 7700 Edgewater Drive. Six additional soil samples were obtained from borings taken on the abutting properties according to an ESE report dated May 31, 1991. Groundwater samples were analyzed from the previously installed groundwater well and

The five off-site soil samples taken at a depth of 6 to 7 feet bgs range from 1.4 to 21,000 ppm TPH as motor oil. These soil samples were tested for PCBs and organochlorine pesticides. None were detected. A grab groundwater sample was taken from approximately 50 feet up-gradient of the ESE-1 monitoring well. This water sample contained 110 ppm TPH as motor oil and 240 ppb (parts per billion) Lindane, an organochlorine pesticide. The groundwater sample analyzed from ESE-1 had 1.3 ppm TPH as motor oil. No PCBs or organochlorine pesticides were detected.

ESE proposed that the source of the contamination was from the existing fill brought on- site and not from activities associated with 7700 Edgewater Drive. Ms. Chapman concurred with this suggestion. Ms. Chapman's letter concluded: "Currently, there is no guideline policy available from the Regional Quality Control Board regarding contaminated bay fill. While the level of Lindane found poses a concern (drinking water maximum contaminant level is 5 ppb), this was not detected in the groundwater sample from ESE-1. Since the contamination does not appear to be a result of activities at 7700 Edgewater Drive, we will not require The Travelers Company to do further work on their property at this time. Additional work may be required if a guideline policy is developed, or if there is a change in site conditions that could adversely impact human health, the environment, or groundwater quality. This letter does not preclude any other environmental agency from requiring additional investigation."

GOVERNMENT RECORDS REVIEW

Regulatory compliance is a primary element of an ESA. Failure to comply with governmental regulations can result in fines, and can expose businesses or individuals to liabilities from which the law would otherwise shield them. The presence of hazardous wastes or hazardous materials, on-site or at neighboring sites, may present certain liabilities. Environmental Data Resources, inc. (EDR) provided the most recent information regarding the hazardous materials sites identified below." Sites of potential environmental concern are described at the end of this section in Table 1.

The Federal Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), also known as the Superfttnd Act, protects the victims and the environment in the event of a hazardous materials spill. This act primarily addresses cleanup of designated Superfund hazardous waste sites (HWS). To achieve its stated purpose, CERCLA established a hazardous Substances Trust Fund, the Emergency Response Trust Fund, and the Post-Closure Liability Trust Fund. These funds compensate the victims and provide money necessary for the decontamination of the environment. The EPA compiles a list of known contaminated sites that are under consideration for the Superfund List. This list is known as the CERCLIS database. According to the May 2004 version of this document, no CERCLIS site is located within a 0.5-mile radius of the subject property. The US EPA maintains the National Priority List (NPL) under CERCLA 42 U.S.C. Section 9601 (1985). Once a site has been designated on the CERCLIS, the EPA ranks it to determine the potential risk to human health and the environment. Only those CERCLIS sites which present the greatest risk are added to the NFL, which qualifies the sites to receive CERCLA remedial funding. According to the July 2004

14 104228 7700 Edgesvater Dr., Oakland version of this document, no NPL site is located within a 1.0-mile radius of the subject property.

2. The EPA's Resource Conservation and Recovery Act (RCRA) Program identifies and tracks hazardous waste from the point of generation to the point of disposal, in addition to enforcing penalties against violators. The RCRA Facilities database is a compilation by the EPA of facilities which generate, store, transport, treat or dispose of hazardous waste. Small quantity generator (SQG) facilities produce between 100 kilograms and 1,000 kilograms of hazardous waste per month. Large quantity generator (LQG) facilities produce more than 1,000 kilograms of hazardous waste per month.

According to the August 2004 listing of hazardous waste treatment, storage and disposal facilities (TSDs), no TSD facility is located within a 0.5-mile radius of the subject site.

The Resource Conservation and Recovery Information System - TSDs CORRACTS report contains information pertaining to TSDs which have conducted, or are currently conducting, a corrective action as regulated under RCRA.

According to the June 2004 version of the CORRACTS document, one CORRACTS facility is located within a 1.0-mile radius of the subject property.

According to the August 2004 listing of hazardous waste generators, no large quantity generator (LQG) facilities and seven small quantity generator (SQG) facilities are located within a 0.5-mile radius of the subject property.

3. The California Environmental Protection Agency (Cal-EPA) maintains the California Facility Inventory Database (Ca.-FIID). The Ca.-FID contains an historical listing of active and inactive UST locations from the State Water Resources Control Board. According to the October 1994 version of this database, the subject property is not listed on the Ca.-FID database.

4. The California Department of Toxic Substance Control's (DTSC) Annual Work Plan (AWP, formerly BEP), also known as Cal-Sites, is a listing of known hazardous waste sites. According to the June 2004 version of this document, one AWP site is located within a 1.0-mile radius of the subject site.

The DTSC maintains a database (known as the Cal-Sites ASPIS list) that includes potential or confirmed hazardous substance release properties. According to the June 2004 version of this database, one ASPIS site is located within a 1.0-mile radius of the subject property.

The DTSC maintains the California Hazardous Materials Incident Report System (known as CHMI[RS), which contains information on reported hazardous material incidents (accidental releases or spills). According to the December 2003 version of this database, 31 CIHIMIRS sites are located within a 1.0-mile radius of the subject property.

The DTSC developed a site-specific expenditure plan as the basis for an appropriation of Hazardous Substance Cleanup Bond Act funds, known as the Bond Expenditure Plan (BEP). This list is not updated. According to the January 1989 version of this database, one BEP site is located within a 1.0-mile radius of the subject property.

The subject property was listed on one of the databases searched. The Edgewater Park Plaza and the San Francisco Girl Scout Council (7700 Edgewater Drive) were listed on the HAZNET database. According to the HAZNET database, waste oil and waste hydrocarbon solvents have been manifested from the subject property. These hazardous wastes were removed from the subject property and disposed of by a hazardous waste

17 104228 7700 Edgewalei- Dr.. Oakland recycler. Information obtained during the site visit indicated that hazardous waste is no longer generated at the subject property. No violations, spills, or releases were listed in the database for the subject property address. The closest listed facility is located immediately northeast (up-gradient) of the subject property. This facility (Goodyear Tire and Rubber Company, 7727 Oakport Street) was listed on LUST, Cortese and CA FIID UST databases. At the time of the site visit, this adjoining property was vacant and an existing sign indicated that it was most recently occupied by a Volvo automobile dealership. According to the LUST database, a diesel fuel release from an underground tank was found to have impacted the soil only. The impacted soil was excavated and removed from this adjoining property and the case was closed on August 1, 1994. Based on this LUST site's "Case Closed" status and that the release was limited to the soil only, it is the opinion of BA Environmental that there is a low potential for environmental impact to the subject property from this adjoining LUST site. Based on the locations, distances and statuses of the remaining facilities identified in the database, there is a low potential for environmental impact due to off-site sources.

FINDINGS, CONCLUSIONS AND RECOMMENDATIONS The subject property consists of two 2-story office buildings consisting of approximately 205,000 square feet, situated on an approximate 10.5-acre parcel of land. Other improvements include surface asphalt parking and landscaping. The subject property was developed from vacant land in 1970. The review of historical documents revealed that the subject property was occupied by undeveloped mudflats, meandering stream channels, and marshland from prior to 1939 until sometime prior to 1958. By 1958, the subject property was vacant land that appeared to be fill material brought on-site, covering the pre-existing wetlands. The subject property was developed into the existing office buildings and associated asphalt- paved parking lots in 1970 and 1971. The subject site has been used as office space since that time by government agencies, non-profit organizations, lawyers, consultants, accountants, corporations, software firms, and various businesses. Precision Truck Driving School has used the parking lot in the northern portion of the subject property since the late 1990's.

Historically, the adjacent properties were occupied by undeveloped marshland from prior to 1939 until at least 1946. By 1958, the adjoining properties consisted of vacant land that appeared to be fill material. Elmhurst Channel was present to the northwest of the subject property in 1939. The area northwest of the subject property, across Elmhurst Channel, was developed into the existing large commercial buildings after 1993. Commercial development in the areas northeast and southeast of the subject property began in the 1960's and was completed by 1982. The area southwest of the subject property, across Edgewater Drive, has consisted of commercial development and vacant land since at least 1982.

In addition, two full and four empty 55-gallon drums of acid free restroom cleaner and small quantities of normal household cleaners were observed in a janitorial closet. No staining was observed on the surfaces beneath containers or paint or cleaning supplies.

No areas of stained soil, stained asphalt or concrete, or distressed or discolored vegetation, were observed on-site during the site reconnaissance.

BA Environmental did not observe issues of environmental concern such as significantly stained pavement or concrete floors, underground storage tanks (USTs), aboveground storage tanks (ASTs), floor drains, waste water clarifiers, or significant hazardous materials usage or storage at the subject property.

BA Environmental reviewed information on file at the Alameda County Environmental Health Department (ACDHD) regarding previous soil and groundwater investigations undertaken at the subject property. A Phase II soil and groundwater investigation report by Environmental Science and Engineering (ESE) dated April 11, 1991, summarized the results of 19 borings drilled in the northern parking lot area of the subject property. Soil samples taken at depths ranging from 2.5 to 6.5 feet bgs ranged from 21 to 1,600 parts per million (ppm) TPH as motor oil. A groundwater monitoring well (ESE-1) was installed and sampled at this time. The groundwater sample measured 0.84 ppm TPH as motor oil and no BTEX compounds were detected. Further work was requested by the ACDEH to delineate the extent of contamination and determine if the source was from 7700 Edgewater Drive. Six additional soil samples were obtained from borings taken on the abutting properties according to an ESE report dated May 31, 1991. Groundwater samples were analyzed from the previously installed groundwater well and from a boring located approximately 50 feet up-gradient from the groundwater monitoring well. The five off-site soil samples taken at a depth of 6 to 7 feet bgs ranged from 1.4 to 21,000 ppm TPH as motor oil. These soil samples were tested for PCBs and organochiorine pesticides. None were detected. A grab groundwater sample was taken from approximately 50 feet up-gradient of the ESE-1 monitoring well. This water sample contained 110 ppm TPH as motor oil and 240 ppb (parts per billion) Lindane, an organochiorine pesticide. The groundwater sample analyzed from ESE-1 had 1.3 ppm TPH as motor oil. No PCBs or organochiorine pesticides were detected. ESE proposed that the source of the contamination was from the existing fill brought on-site and not from activities associated with 7700 Edgewater Drive. A letter on file at the ACEHD dated June 5, 1991, concurred with this suggestion, concluding: "Currently, there is no guideline policy available from the Regional Quality Control Board regarding

While the level of Lindane found poses a concern (drinking water maximum contaminant level is 5 ppb), this was not detected in the groundwater sample from ESE-1. Since the contamination does not appear to be a result of activities at 7700 Edgewater Drive, we will not require The Travelers Company to do further work on their property at this time. Additional work may be required if a guideline policy is developed, or if there is a change in site conditions that could adversely impact human health, the environment, or groundwater quality. This letter does not preclude any other environmental agency from requiring additional investigation."

BA Environmental reviewed selected government environmental databases. The subject property was listed on the HAZNET database. The Edgewater Park Plaza and the San Francisco Girl Scout Council (7700 Edgewater Drive) were listed on the HAZNET database. According to the HAZNET database, waste oil and waste hydrocarbon solvents have been manifested from the subject property. These hazardous wastes were removed from the subject property and disposed of by a hazardous waste recycler. Information obtained during the site visit indicated that hazardous waste is no longer generated at the subject property. No violations, spills, or releases were listed in the database for the subject property address. The closest listed facility is located immediately northeast (up- gradient) of the subject property. This facility (Goodyear Tire and Rubber Company, 7727 Oakport Street) was listed on LUST, Cortese and CA FID UST databases. At the time of the site visit, this adjoining property was vacant and an existing sign indicated that it was most recently occupied by a Volvo automobile dealership. According to the LUST database, a diesel fuel release from an underground tank was found to have impacted the soil only. The impacted soil was excavated and removed from this adjoining property and the case was closed on August 1, 1994. Based on this LUST site's "Case Closed" status and that the release was limited to the soil only, it is the opinion of BA Environmental that there is a low potential for environmental impact to the subject property from this adjoining LUST site. Based on the locations, distances and statuses of the remaining facilities identified in the database, there is a low potential for environmental impact due to off-site sources.

BA Environmental has performed a Phase I ESA, in conformance with the scope and limitations of ASTM Practice E 1527-00, of the property located at 7700 Edgewater Drive, in the City of Oakland, California. Any exceptions to, or deletions from, this practice are described in the Introduction section of this report.

20 104228 7700 Edgewater Dr., Oakland BA Environmental recommends the following: Continue the existing asbestos Operations and Management Program, informing contractors and tenants about the ACMs identified within the buildings. If confirmed ACMs are scheduled for renovation or demolition activities, they should be removed by a licensed asbestos abatement contractor; and Abandon the monitoring well located on the northern portion of the subject property under the supervision of the ACEHD, in accordance with all state and local regulations.

EXECUTIVE SUMMARY

Introduction

ENSR was retained by CRIIMI MAE, Inc. to perform a Phase I Environmental Site Assessment (ESA) of the Edgewater Park Plaza property located at 7700 Edgewater Drive in Oakland, California. (Figure 1: Site Location Map). The agreed upon objective of the investigation was to identify known and potential environmental costs and liabilities associated with the ownership, use, and operation of the subject site.

The subject site consists of approximately ten acres of land improved by four, two-story office buildings located on the east side of Edgewater Drive (see Figure 2: Site Plan). The buildings are serviced by municipal water and sewer and are heated by natural gas. The buildings were constructed in 1973 and comprise approximately 205,000 square feet. Precision Truck School leases approximately one acre of the northeast portion of the parking lot at the subject site for training purposes. Landscaped areas were observed along the north, south, east, and west boundaries of the property as well as in the courtyards located between Buildings A and B and Buildings C and D. Paved parking surrounds the buildings. The boiler room comprised of approximately 500 square feet is located in an exterior alcove on the southwest side of Building D and houses two chillers and a boiler. Site photographs are contained in Attachment C.

Horizon Aerial Lifts, LAMAW Lodge, Nisei Plastics, Goodyear, and Italian Ceramic Tile abut the Site to the north and northeast. Adjacent to the south and southeast are ATS, Sterling Environmental Corp., AFCO'Electronics, Milligan-Spika Comp Industrial Sales, and Polymers Inc. Edgewater Drive borders the site to the south and southwest. Elmhurst Channel borders the site to the west and northwest.

On-Site Issues

Based on the ERIIS database report, the subject site was identified on the California Regional Water Quality Control Board's (RWQCB) Spills, Leaks, Investigations, and Cleanups Report (SPILLS). In addition, ENSR reviewed files at the Oakland Fire Department Office of Emergency Services. The analysis of soil and groundwater samples collected by Environmental Science & Engineering, Inc. (ESE) in January of 1991, indicated that elevated levels of petroleum hydrocarbons were present at the northeastern site boundary In May 1991 additional soil and groundwater at the request of the Alameda County Department of Environmental Health (ACDEH). ESE determined from this investigation that the source of contamination was a result of existing fill. ESE indicated that the available historical information suggests no industrial opFT 'curred at the subject site or the abutting properties, which would have generated the detected contaminants In June 1991, ACDEH determined that since there is no evidence to indicate that the contamination was a result of on-site activities, no further action was deemed necessary at the subject site.

According to ENSR's historical review, the subject site was undeveloped marshland prior to the development of the on-site buildings. Therefore, as determined by ESE, fill material was utilized prior

2C48-i3-lCJ April 1998 ENR to construction of the subject site. Based on the information reviewed, site operations have not contributed to the contamination identified on-site.

During ENSR's on-site assessment of the Edgewater Park Plaza, a limited asbestos inspection was conducted; ten samples were collected and analyzed. A toawas_e4ed-in two simp1es of spray- on ceiling texture, brown cove base mastic, and brown/blue damaged resilient sheet flooring under 12" X 12" beige floor tile. See Attachment E for Asbestos Analytical Results.

A limited lead-based paint survey was also conducted by ENSR as part of the authorized scope of work. During the survey, ten samples were collected and analyzed (see Attachment F for the analytical results). None of the samples analyzed exceed the Housing and Urban Development's definition of lead- based paint.

Off-Site Issues

Based on a review of the available regulatory database information and a property line visual inspection of adjacent properties, no off-site issueswere--identified. The ERIIS database report is included as Attachment D.

Regulatory Compliance Issues

There were no environmental regulatory compliance problems/concerns identified relative to on-site activities. The subject site is used strictly for commercial purposes. Neither Edgewater Park Plaza nor any of the existing tenants were identified on any of the regulatory databases reviewed.

Conclusions and Recommendations

During the course of this due diligence investigation, evidence was found to indicate the presence of an on-site contamination problem. However, based on the case closure provided by the ACDEH, it appears that additional evaluation is not warranted at this time. ENSR concludes that the on-site contamination will not materially impact the use of the Subject Property. During our limited asbestos survey performed at the subject site, three types of asbestos-containing materials were identified. The spray-on textured ceiling and the brown cove base mastic were in at the time of the survey. ENSR recommends that the damaged floor tile in the men's restroom be covered with new flooring or- removed. In addition, ENSR recommends that an asbestos Operations and Maintenance Plan be prepared for the property. The cost to prepare such a plan is $ 750.

1' EN'R EXHIBIT A Responses to Environmental Site Assessment Form Edgewater Park Plaza

The information categories are as follows:

A. Prior Use

1. Past uses of the property.

To determine historical uses of the subject site, ENSR reviewed aerial photographs, tax records, building department records, deed records, and city directories. In addition, ENSR conducted an interview with Ms. Julia Plummer, Building Manager, of 7700 Edgewater Drive. Sanborn Fire Insurance Maps for the subject site were not available.

Aerial photographs dated 1947, 1953, 1959, 1968, 1973, 1979, 1985, 1990, and 1996 were reviewed. The 1947, 1953, and 1959 aerial photographs depict the subject site as vacant land or what appears to be marshland. The 1973, 1979, 1985, 1990, and 1996 aerial photographs depict the property in the same configuration as it presently exists with four buildings, adjacent landscaping on all sides, and associated parking areas.

Aerial photograph data was confirmed using city directories. Historical city directories for the years 1943, 1948, 1967, 1969, 1973, 1978, 1983, 1989, 1994 and 1997 were available for review. The city directories for 1943, 1948, and 1967 show no listing for the subject site's address. Directories dating between 1973 and 1997 list Edgewater Park Plaza as occupant of the subject site address. Edgewater Park Plaza varied in occupancy from approximately 40 to 125 tenants.

According to Permits records available at the Building Department, the subject site's building plans were submitted and approved by the Alameda County Building Department in 1971. Permit records show that the property was developed in 1973. ENSR observed no permits for underground storage tanks at the subject site.

According to records at the Alameda County Tax Assessor's office and the Alameda County Recorder's office, former owners of the site back to 197b include various partnerships and corporations. According to Ms. Plummer, previous owners did not conduct manufacturing at the subject site.

2. Whether the past use of the property involved substantial amounts of hazardous substances.

According to Ms. Julia Hummer, Property Manager, the Edgewater Park Plaza complex has historically been utilized strictly as office space with the exception of a deli that is located on the first floor of Building A.

2048-028-100 April 1998 ENR Precision Truck School has leased approximately one-acre of the northeast parking lot at the subject site for approximately two years. A customer representative for Precision Truck School indicated that the site is utilized strictly for training purposes and that all truck maintenance and fueling activities are conducted off-site. Currently six tractors, six trailers, two pickup trucks and associated equipment are kept on-site.

Based on this information, it does not appear that past uses of the property involved substantial amounts of hazardous substances.

3. The years during which each past operation took place.

Based on available historical information, there were no prior uses of the subject site.

4. If the prior use of the property is unknown, the type of area within which the facility is located (i.e., undeveloped, residential, commercial or industrial).

Not applicable.

B. Acreage

1. The size of the property in acres.

According to assessment records, the subject site consists of approximately ten acres.

2. Whether the acreage is comprised of commercial or mixed-use land.

During ENSR's on-site assessment, the subject site was observed as being utilized strictly as commercial office space. According to the Alameda County Zoning Department, the subject site is zoned as Heavy Industrial.

C. USTs

1. Active USTs present on the property.

Ms. Plummer indicated that there are no known USTs on the subject site, and no active USTs were observed by ENSR during the site inspeci .ett5search did not reveal any registered USTs on the subject site.

2. The age of each UST.

Not applicable.

3. Whether and when the USTs have been tested for leaks.

Not applicable.

204-028.100 April 1998 ENR 4. Whether any USTs have been found to be leaking.

Not applicable.

5. Whether any UST leaks are being (or have been) remediated and whether there was any regulatory oversight.

Not applicable.

6. Closed-in-place, removed or abandoned USTs on the property.

There was no evidence of closed-in-place, removed, or abandoned USTs on the property.

7. The number of years for which any UST has been abandoned.

Not applicable.

8. USTs located or likely located on adjacent properties and whether such USTs are known to have leaked and/or been remediated.

Based on municipal information, the ERIIS database report, and ENSR's property-line observations, USTs were not observed at abutting properties.

9. USTs located on properties within 1/4 mile of the subject site, the gradient and level of the water table between the UST location and the subject site, the capacity and contents of such USTs and whether such USTs are known to have leaked and/or been remediated.

ENSR reviewed a list of registered underground storage tank (RST) and leaking underground storage tank (LRST) databases from the ERIIS database report. According to municipal records and information from the ERIIS database report, two LRSTs and one RST are located within a 1/4-mile radius of the subject site:

The Hooton Property located at 7307 Edgewater Drive, 370 feet northwest and separated from the subject site by the Elmhurst Channel, is listed as a LRST site, the details of which are not indicated by the ERIIS report; however, the status of the case was reported as closed.

Grand Auto Distribution Center located at 7200 Edgewater Drive, located 1200 feet northwest and separated from the subject site by the Elmhurst Channel, reported a release of hydrocarbons in May of 1990. The case was closed in March of 1995. No further details of the release were provided.

Given that these cases are closed and the facilities are beyond the Elmhurst Channel, ENSR does not consider these sites to represent an adverse environmental concern to the site.

2048-023-100 April 1998 3 ENR General Automotive, located at 7200 Edgewater Drive, has four RSTs with no spills or releases reported. The General Automotive facility is located 1200 feet northwest and is separated from the subject site by the Elmhurst C.hannel.

D. Petroleum and Hazardous Materials Storage

1. Storage of petroleum or hazardous substances (including lubricants, fuel, solvents, paints, cleaners, chemicals, and wastes containing any of these substances) in drums or other containers.

The subject site is used for administrative purposes. Maintenance employees utilize household cleaning supplies and paints for the general upkeep of the units. ENSR observed approximately 5.0 gallons of paint, paint thinners, wood finish, and wall and carpet adhesives in one-quart, one- gallon, and five-gallon containers stored on-site. No significant staining was observed during ENSR's inspection. However, in storage room 737 ENSR observed two open one-gallon containers of paint, a 3.5-gallon cracked adhesive container and one open five-gallon container of an unknown powder-like substance that was speculated to be dried paint, and one torn package of dry concrete.

Chemicals utilized for treatment of cooling tower water are stored in five-gallon containers in the boiler room. In addition, ENSR observed one unlabeled, one-gallon jug of what appeared to be chlorine and a one-gallon container of refrigeration oil in the boiler room. ENSR spoke with Scott, a service representative from Linford Services of Oakland, a company that services the chillers regularly. According to Scott, the oil is changed approximately once a year and any oil that is removed from the system is taken off-site by Linford Services. Scott also indicated that the chemicals stored on-site are mainly used as corrosion inhibitors. ENSR also observed a 16-gallon drum of Sanacor corrosion inhibitor in the boiler room area. The integrity of the containers was satisfactory and no staining in association with the containers was observed during ENSR's inspection.

ENSR observed two, five-gallon containers of Chevron Gas and Steam Turbine Oil stored in the AC/15 Mechanical Room in Building C. The integrity of the containers was satisfactory and no staining in association with the containers was observed the day of the site visit. According to Mr. Armando Rivera, Maintenance Engineer, the oil is utilized as lubricant for the compressors located in mechanical room AC/6 Building A and mechanical room AC/15 located in Building C. According to Mr. Rivera, the compressors supply air to the building thermostats, which are pneumatically operated.

ENSR observed various cleaning supplies and chemicals in the janitorial closets and storage rooms of the Subject Facility. Janitorial supplies such as bathroom disinfectant, biodegradable solvent degreaser emulsion, carpet steam cleaner, Clean & Sheen, furniture polish and steel cleaner were noted throughout the four buildings. No significant staining was noted in any of the rooms observed by ENSR. ENSR observed three empty 55-gallon containers of Spartan non-acid disinfectant bathroom cleaner in the Janitorial closet on the second floor of Building C.

2048-028-100 April 1998 4 Et{R According to Ms. Plummer, wastes generated at the subject site include paper and cardboard which is hauled off-site by L & K Recycling of Union City, California. Municipal waste is hauled off-site by Waste Management. ENSR contacted Waste Management to determine what disposal facilities they utilize. A CERCLIS search on the Chemical Information System (CIS) was performed to determine if any of the disposal facilitates utilized by the site have been investigated for environmental matters. The Altamonte Landfill used by Waste Management was not identified on the CIS system.

2. The amount stored per month.

According to Mr. Rivera, the quantities indicated in the previous section are typical.

3. Where and how such substances have been stored (i.e., indoor, outdoors, on pavement or unpaved ground, and whether curbed).

Chemicals observed were stored in various indoor storage locations on shelves or wooden floors throughout the four buildings.

E. Spills or Releases

1. The size, location, nature, and date of any spills or release of materials containing petroleum or hazardous substances (including fuels) that have occurred or are suspected as having occurred on the property.

In November of 1993, a broken hot water heater released water into an on-site elevator pit. The elevator company pumped the hydraulic oil tank and the elevator pit to remove the accumulated oil and water mixture. According to Chemical Waste Management's (0MW) Waste Profile, approximately 220 gallons of a mixture of petroleum oil and/or grease, water, dirt, and inert solids were removed from the subject site.

Ms. Plummer did not have any knowledge of any other reported spills or releases of materials containing petroleum or hazardous substances on the subject site.

2. Whether and how any spills or releases were investigated or remediated.

ENSR reviewed the MSDS sheet for the hydraulic oil utilized by U.S. Elevators. The hydraulic fluid is not comprised of PCBs or other chemical constituents noted to be of a significant health risk. Ms. Plummer stated that to her knowledge there were no releases outside of the building. The elevator pit is constructed of concrete and was noted to be in good condition.

3. Any regulatory oversight of the remediation conducted.

No regulatory oversight of the spill was necessary, as the hydraulic oil was never released from the elevator pit. U.S. Elevator stored the oil and water mixture in 55-gallon drums, which

2043-028-100 Apri' 1998 ENR

were subsequently removed from the property and incinerated in a CWM facility in Azusa, California.

F. Surface Waters

1. Surface water areas (including ponds, lagoons, surface impoundments and watercourses) currently or formerly on the property.

ENSR did not identify any surface water bodies on the subject site. Ms. Plummer indicated that all on-site storm drains discharge to the Elmhurst Channel bordering the property to the northwest, which ultimately drains into the San Leandro Bay.

2. Whether the surface waters receive non-hazardous process wastewater, non-contact cooling waters, rainwater from industrial areas, or process wastewater containing hazardous constituents.

Not applicable.

3. Whether or not the surface water area has been effectively lined.

Not applicable.

4. Whether the property is located adjacent to, upgradient of, or on a watershed area near a reservoir serving as a source of potable water.

The subject site is not located adjacent to or upgradient of, or on a watershed area near a reservoir serving as a source of potable water.

G. Groundwater

1. Whether the property is located in an area which draws its drinking water from underground wells.

The subject site is provided with potable water from the East Bay Municipal Utilities District, which draws water from the San Leandro Reservoir.

Based on a review of the USGS topographic map of the subject site, groundwater flow in the vicinity of the site is inferred to flow to the northwest towards the Elmhurst Channel.

2. Whether there is a groundwater contamination problem in the vicinity.

ENSE reviewed files at the Oakland Fire Department Office of Emergency Services. Environmental Science & Engineering Inc. (ESE) performed subsurface investigations and installed a monitoring well at the subject site in April 1991. A total of five groundwater samples were collected from the site. Two were collected on April 2 and May 21, 1991 from

2040-028.100 April 1998 6 Et{R well ESE-1. Total petroleum hydrocarbon (TPH) concentrations were detected at 0.84 and 1.3 parts per million respectively. Three soil samples were collected and concentrations of TPH were detected at 0.97, 4.9 and 110 ppm. The sample with the highest concentration was also found to contain Lindane at a concentration of 0.24 ppm. ESE determined from these results that the first two groundwater samples were silty grab samples from soil borings, and were most likely not representative of actual groundwater conditions. The concentrations of TPH and the presence of Lindane most likely occurred due to contact with the surrounding soil. The source of Lindane was unknown and was not detected in the monitoring well sample. ESE suggested that the source of contamination is from the fill. ESE indicated that the available historical information suggests that no industrial activity has ever occurred at the subject site or any of the abutting properties. ESE also determined that the shallow groundwater beneath the site is slightly brackish and probably has limited potential for beneficial use. In June 1.991, ACDEH determined that since there is no evidence to indicate that the contamination was a result of on-site activities, no further action was deemed necessary at the subject site.

3. Wells located on the property.

According to a file review at the Oakland Fire Department and ENSR's site inspection, one monitoring well exists at the northeast boundary of the subject site.

H. Fill and Land Disposal

1. Fill material deposited on the property.

A previous report generated by ESE indicates that aerial photographs from 1943 and 1959 depict the area as marshland in the process of being drained, filled and graded. ENSR therefore concludes that fill was deposited at the subject site.

2. Whether any fill used was certified clean, or believed to be clean or some other fill.

According to results of a subsurface investigation performed by ESE in January through May of 1991, on-site fill was determined to be contaminated with petroleum hydrocarbons and PCBs. ESE indicated that the available historical information suggests no heavy industrial activity has ever occurred at the subject site or any of the abutting properties which would have generated the detected contaminants. In June 1991, ACDEH, determined that since there is no historical evidence that the contamination was a result of activities at 7700 Edgewater Drive, and there is no guideline policy from the RWQCB regarding contaminated bay fill, no further work was deemed necessary at the subject site. In June 1991, ACDEH determined that since there is no evidence to indicate that the contamination was a result of on-site activities, no further action was deemed necessary at the subject site.

3. On-site waste disposal of construction or demolition material

ENSR did not identify any evidence of on-site disposal of construction or demolition materials.

2048-028-100 April 1998 7 ENR 4. Whether it has been shown to be free of contamination.

Not applicable.

5. On-site disposal of other wastes (i.e., sludge, manufacturing byproducts, or other wastes suspected to contain petroleum or hazardous substances).

No on-site disposal of any wastes is known to have occurred on the Subject Property.

6. Whether on-site disposal is reasonably suspected as having taken place.

Available information does not indicate that on-site disposal has occurred.

I. Enforcement and Litigation

1. Whether the property has ever been cited for environmental regulatory violations.

A review of available municipal records does not indicate the property has been cited for environmental regulatory violations.

2. The number of citations received.

Not applicable.

3. Whether any citations received were for non-recurring environmental regulatory violations.

Not applicable.

4. Whether the underlying violations have been corrected.

Not applicable.

5. Whether the property is or has been subject to an administrative or judicial action or order.

A review of available municipal records did not indicate that the subject site currently is, nor has been, subject to a judicial or administrative action or order relative to environmental matters.

6. Oral or written inquiries from regulatory authorities regarding environmental contamination.

A review of municipal records indicated that the Alameda County Department of Health was aware of contaminated fill at the subject site and deemed that no further action was required.

2048-028100 APnI 1998 8 EN'R According to ACDEH, there are currently no policies available from the RWCQB regarding contaminated bay fill.

7. Mandatory investigation and remediation currently ongoing at the property or expected upon sale or closure of the property.

Ms. Plummer reported that no environmental investigation or remediation is currently ongoing at the subject site.

8. Whether the property appears on the NPL (National Priorities List) or any other federal or state list of properties slated for evaluation and remediation.

The ERIIS database report does not indicate that that subject site is on the NFL or any other federal or state list of properties slated for evaluation or remediation.

9. Claims by neighbors, environmental groups or others concerning alleged environmental contamination.

According to Ms. Plummer and municipal records, there have been no claims made concerning the subject site.

10. Oral or written threats of suit or commenced suit that have been communicated to the borrower or property manager.

Ms. Plummer reported no knowledge of oral or written threats of suit or commenced suits.

J. Contamination

1. Known contamination of the property in either the soil, surface water or groundwater.

It is known that there is limited contamination in the soil and groundwater at the northeastern boundary of the subject property. Upon review of previous reports, the contamination is a result of existing fill and not a result of activities at the subject site or those of adjacent properties.

2. Whether areas of contaminated soil are paved or covered by the footprint of a building.

Currently the known areas of contaminated soil are covered by pavement. It is also possible that the fill material under the building footprint is contaminated.

3. Polychlorinated biphenyls ("PCBs") in either minor or significant electrical components.

Two exterior transformers are located on the subject site. Ms. Plummer stated that both transformers are owned by Pacific Gas & Electric (PG & E). ENSR did not identify any sign of

2043-028-100 April 1998

9 EN'R seepage and/or leakage from these units during the time of the assessment. No stickers regarding PCB content were observed on either transformer. PG & E is responsible for maintenance.

4. If there is no information regarding PCBs, whether the property contains structures built before 1978.

Based on available information, the buildings at the subject site were constructed in 1973.

5. Whether there has been any testing for radon gas, and if so, whether the levels shown are within EPA, state or local recommendations.

Ms. Plummer was not aware of any prior radon testing at the subject site. In addition, the building at the site does not contain a basement.

6. Whether the property is located in a high risk or low risk area for radon gas.

Radon gas levels are highly site-specific and are influenced by soil and building conditions, including pressure differentials between the soil and the building. The USEPA has established a guideline threshold of 4.0 picoCuries per liter (pCi/I) of air, above which there may be adverse health risks if exposure is continued over a prolonged time (generally 70 years). According to the ERIIS Database report, the subject site is located in Zone 2 indicating it to be a moderate risk area for radon with levels between greater than or equal to 2 pCi/L and less than or equal to 4 pCi/L. However, as

K. Asbestos

1. Whether sampling or relevant information shows that asbestos is not present.

According to Ms. Plummer, asbestos abatement was performed at the subject site in 1990 and f TPi.CIiernicasf dalurnTted su eycftlubjectsit in January of 1990 ------a-n-d--d-el-ec-l-e-d-a-s-5-e-sTo-s--o n-the- roof, fire doors and mastic under 12" floor tile. n.j; Chemicals also generated a Management Plan for the Edgewater Park Plaza in July of 1990. In February 1991, ECI removed asbestos containing floor tiles and spray-on ceiling material from the first floor bathrooms and the second floor corridor areas respectively at Edgewater Park Plaza. BCP Construction Inc. conducted an abatement of approximately 6,000 square feet of asbestos containing floor tile, mastic and particle floorboard in July 1991. The location of the abatement was not indicated in the BCP report. In February 1993, ProTech Consulting and Engineering Inc. removed asbestos flooring mastic found in suites 360 and 400 in Building B. ProTech indicated that no friable asbestos material was located in the contract removal area.

On March 25, 1998, ENSR conducted a limited screening asbestos survey of the subject site as part of this assessment. The details of the survey are provided in the following paragraphs

2048-028-100 April 1998 10 ENR 2. Whether asbestos is known to be present and is limited to floor and ceiling tile or includes insulation.

During ENSR's assessment, a limited screening asbestos survey was conducted at the buildings on-site. The purpose of this survey was to determine the presence or absence of friable and non-friable ACMs in the buildings. The survey consisted of a visual inspection coupled with bulk sampling of suspected and readily accessible ACM in accordance with the prescribed sampling protocol established by Citimae. A total of ten samples were collected and analyzed. The analytical results indicate that four samples contain greater than one percent asbestos. The asbestos analytical results are summarized in Table I below and provided in Attachment E.

3. Whether asbestos is in friable condition.

ENSR observed spray-on ceiling texture which is considered to be friable, on the ceilings of the northeast stairwell, and the second floor hallway of Building D.

2048-028-100 April 1998 MR 4. Whether asbestos is suspected though no sampling has been conducted.

In addition to the materials sampled, ACMs are suspected in the fire doors of each of the buildings. ENSR did not take a sample of the fire doors as these materials were sampled in prior investigations

5. Quantities of suspected asbestos.

Approximately 500 square feet of asbestos containing linoleum was found in the second floor men's restroom of Building D. Approximately 500 square feet of spray-on ceiling texture found in Building D was found to contain asbestos. Stairwells and hallways were found with similar materials throughout the buildings on-site and are suspected to be ACMs. The cove base mastic material in Room 803 of Building D was found to be asbestos containing and is utilized in various suites throughout the four buildings.

L. Indoor Air Quality

1. If the property is industrial, whether the permissible exposure limits (PELs) to toxic air contaminants issued under the Occupational Safety and Health Act have been exceeded.

The facility is used as a multi-tenant office building. Manufacturing activities were not observed during ENSRs site inspection.

2. The condition of the HVAC system (i.e., are vents blocked, are ventilating fans not operating, are the air ducts too narrow, are there too few air vents).

According to Ms. Plummer, no problems have been cited regarding the HVAC systems.

3. Written complaints or suits filed by employees or residents of the property concerning indoor air contaminants.

According to Ms. Plummer, there have been no complaints about indoor quality air.

4. Whether there are no known air quality problems.

Ms. Plummer reported that there are no known air quality problems on site.

M. Other

1. Medical waste discharges.

According to Ms. Plummer, only office and domestic waste is generated at the subject facility.

2048-028-100 Apn 1998 12 ENR

2. Waste discharges (other than purely domestic waste) to a publicly owned treatment works.

Effluent water from the cooling tower is discharged to the sanitary sewer system. According to Linford Services, the water treatment chemicals utilized in the HVAC system can be safely discharged to the sanitary sewer system.

3. Active or abandoned septic systems and whether they are residential or commercial.

The buildings are connected to the municipal sewage system. Ms. Plummer indicated that there are no active or abandoned septic systems on the property.

4. Whether the property is subject to the National Pollutant Discharge Elimination System ("NPDES") or any state water discharge permit.

Based on a review of NPDES regulations, it does not appear that the subject site would be subject to such regulations.

5. Whether the facility emits substantial amounts of air pollutants.

Substantial air pollutants are not emitted from the subject facility. The subject facility is not considered a major source of regulated air contaminants.

6. Whether the facility is a hazardous waste treatment, storage or disposal facility.

The subject facility is not a hazardous waste treatment, storage, or disposal facility.

7. Any wetlands contained on the property.

No wetlands were observed or identified on-site.

8. Whether the property is adjacent to a landfill, any industrial facility, property undergoing remedial action or other property reasonably suspected to be contaminated.

The subject site is not adjacent to a landfill or an industrial property reasonably suspected to be contaminated.

9. Whether the property is located within one-half mile of a CERCLIS site.

No CERCLIS sites were identified by the ERIIS database search within Y2 mile of the subject site. In addition, the ERIIS database report did not indicate the presence of any National Priority List sites within a one-mile radius.

2048028-00 Aprd 1998 13 EN'R One NFRAP site, Oakport Development Site, located at Oakport Street and Hassler Way was identified 0.49-mile northeast and separated from the subject site by the Elmhurst Channel. The EPA or an appropriate state agency determines what action, if any, needs to be taken to assess CERCLIS sites. Based on the fact that the site is located beyond the channel and the distance with respect to the subject site, ENSR does not anticipate this facility to present an adverse environmental condition.

N. Lead-based Paint (LBP)

A limited lead-based paint survey was conducted at the Edgewater Park Plaza. During the survey, ten samples of suspect lead-based paint were collected for analysis. The Housing and Urban Development's (HUD's) definition of lead-based paint is 0.5 percent by weight. According to the analytical results, the samples analyzed were not above the HUD standard. The lead-based paint results are summarized in Table II below, and are presented in Attachment F.

Dear Mr. McConn:

The above-mentioned property was inspected for Asbestos-Containing Building Materials on January 20, thru the 24, 1990. All bulk samples taken were submitted to United Asbestos Labs in San Leandro for analyses. The first section of this report titled "Physical Assessment Data" covers the locations, type of materials, quantities, and condition of the ACM. The second section titled "Homogeneous Areas" will show the approximate locations of the ACM in each building. The third section will show the locations of where the bulk samples were taken and the lab reports.

Areas that were not covered in this report are the interior of walls of the buildings, the interiors of the boilers, related pipes, and HVAC systems. All areas with carpet, areas where the inspection would of caused physical damage to the buildings or it's fixtures, and areas that were not accessible at the time of the inspection.

SUMMARY

The inspection was limited in the sense that not all areas were sampled as needed to ascertain the presents of asbestos. The limitations placed on the dollar amount in turn limited the total of samples that could be taken. I don't feel that more samples need to be taken until the areas listed below are involved in renovation or demolition, unless otherwise noted.

1). ROOF AREAS: The roof areas on buildings 100 thru 800 are listed in the Assessment Data and cover the areas where asbestos was found. The concerns that I have are related to the samples listed in Homogeneous area # 14. This area showed asbestos present, it could be either a patch or a complete section of the roof. At this time I feel all the roof areas should be treated as ACM until repair or removal is needed.

2). TENANT IMPROVEMENTS: The main buildings were tested for asbestos in the taping and joint compounds none was found. My concerns are in the improvements made after the main structure was built. The walls in the tenant areas were not sampled due to the amount of samples needed to determine the location of asbestos if any.

3). FIRE DOORS: Homogeneous area # 11 are insulated with asbestos and these doors I believe are scattered throughout the buildings and should be identified as noted in the Assessment Data.

4). 12' FLOOR TILE: Homogeneous area #9 should be retested prior to removal to assure that all mastic is ACM and tile is not.

To the best of my ability the above-mentioned property was inspected and all ACM found was included in this report. Any ACM that may have been overlooked, if found at a later date will be inspected and added to the report at no charge, excluding the areas mentioned above (1 thru 4).

Sincerely,
