7 U.S. Environmental Protection Agency July 2009 (Project No ) EXECUTIVE SUMMARY With this report, Fugro West, Inc., (Fugro) presents the results of environmental site assessment activities completed at th Avenue in Oakland, California (Site). We understand that the Site comprises approximately seven acres of a sixteen acre property currently owned by AC Transit. This Phase II Environmental Site Assessment (ESA) was conducted on behalf of the City of Oakland Environmental Services Division (City), which received funding for this work from a U.S. Environmental Protection Agency (USEPA) Brownfield Grant (Assistance ID No. BF ). The purpose of this ESA was to evaluate the potential presence of hazardous materials in shallow soil, groundwater, and soil-gas at the Site. Results of this investigation will be used to assist the City with proposed redevelopment in the Coliseum BART Redevelopment Area. Previous Phase I and II Environmental Site Assessments (ESAs) conducted by Geomatrix (Geomatrix 2006) and Bureau Veritas (Bureau Veritas 2008) identified recognized environmental conditions and detectable concentrations of metals, petroleum hydrocarbons, and chlorinated solvents in the soil, groundwater, and/or soil-gas on the Site and/or the adjacent AC Transit owned property. Fugro s review of these documents identified several data gaps that required further investigation as described later in this report. Based on findings of the previous Phase I and II ESAs, Fugro compiled the Sampling and Analysis Plan (SAP) dated May 26, The City was given permission by the USEPA to implement the SAP while the document was undergoing review. The Phase II ESA was completed in general conformance with the SAP with the following deviations: An additional grab groundwater sample was obtained from Boring SG-1 and analyzed for volatile organic compounds (VOCs). Grab groundwater sampling utilizing non-disposable equipment was conducted over a two-day period; therefore an additional equipment blank was obtained during the second day of groundwater sampling. No grab groundwater sample was obtained from Boring B-7 because no groundwater was encountered. Subsurface conditions generally comprised alternating layers of firm to stiff, dark brown to light grayish brown lean clay to lean clay with sand to the maximum depth explored of 20 feet. Fill material consisting of clayey, gravelly silt with sand was encountered in Borings B-9 through B-14 at depths ranging from 1.0 to 5.5 feet bgs. Fugro s field geologist screened soil samples in the field using an Organic Vapor Meter (OVM). Sample B-6@7.5 yielded the highest OVM reading of 1.9 parts per million (ppm). No hydrocarbon or solvent odors were encountered in any of the soil samples screened. Depth to groundwater ranged from 2.1 to.5 feet bgs when encountered. No odors or free phase hydrocarbons were detected or observed in any of the grab groundwater samples collected. Sampling, laboratory services, and results of analyses generally conformed with the Data Quality Objectives stated in the SAP with the following exceptions. For soil, two of seven analytes exceeded the relative percent difference (RPD) criteria of 50 percent. The two G:\JOBDOCS\272\ AC TRANSIT\FINAL DOCS\RPT JULY09.DOC ES-1

8 U.S. Environmental Protection Agency July 2009 (Project No ) duplicate soil samples were obtained from fill material at the Site, and although the samples were homogenized in the field, the large RPD is most likely a result of the non-homogeneous nature of the fill. This finding is consistent with Fugro s experience regarding fill at similar sites in the Bay Area. Accordingly, the elevated RPD of the soil samples is not considered significant. Results of the soil-gas samples are considered invalid due to the presence of groundwater in the soil-gas probe as well as the exceedance of RPD criteria for all the soil-gas analytes. Chemical data generated for soil and groundwater samples during this investigation is considered to be complete, accurate, representative, and suitable for the purposes of this Phase II ESA. For soil, no VOCs or polycyclic aromatic hydrocarbons (PAHs) were detected in any of the five samples tested. Total petroleum hydrocarbons as gasoline (TPHg) was detected in two of the thirty-one samples analyzed and total petroleum hydrocarbons as diesel (TPHd) was detected in one of the thirty-one samples analyzed. Detected TPHg and TPHd concentrations were well below their respective Environmental Screening Levels (ESLs) of 0 milligrams per kilogram (mg/kg) for residential land use. Additionally, total petroleum hydrocarbons as motor oil (TPHmo) was detected in seven of the thirty-one samples analyzed, one sample (B-12@1 ) contained 2,0 mg/kg, which exceeded the residential land use ESL of 370 mg/kg. This sample was collected within the shallow fill below the former cannery warehouse. All detected metals concentrations in soil are below their respective total threshold limit concentrations (TTLCs), one of the criteria for classifying soil as hazardous waste. Except for detected concentrations of arsenic, all detected metals are below their respective ESLs for residential land use. Detected arsenic concentrations ranged from 1.7 mg/kg to 12 mg/kg, and are consistent with naturally occurring background values. For groundwater, no petroleum hydrocarbons were detected in any of the grab groundwater samples analyzed. Analysis detected relatively low VOCs in three out of eleven groundwater samples, of which 31 micrograms per liter (µg/l) of 1,2-dichloropropane (B-4) was the only VOC detected that exceeded its respective ESL of 5.0 µg/l. The source of the detected VOCs is unknown. Based on the results of this investigation, as well as from the previous investigations, it appears that there are four localized areas where soil concentrations exceed commercial land use ESLs for certain metals and/or petroleum hydrocarbons. Preliminary remediation costs range from $90,000 to $138,000, which includes a 20% contingency to account for any unforeseen conditions that may arise during redevelopment. This estimate includes disposal of the railroad ties and removal of the UST and associated piping beneath the water tower. Fugro recommends that a complete asbestos containing material (ACM) and lead based paint (LBP) survey be conducted prior to demolition or renovation of the existing structures to confirm the presence of ACM and further refine abatement costs if needed. Total abatement costs are estimated at $260,000 with a 20% contingency. If proposed redevelopment involves dewatering and/or groundwater handling, appropriate planning, permitting, and likely treatment of that groundwater will be required prior to discharge. Any dewatering planned for the Site should consider the presence of VOCs and TPH in groundwater. G:\JOBDOCS\272\ AC TRANSIT\FINAL DOCS\RPT JULY09.DOC ES-2

9 U.S. Environmental Protection Agency July 2009 (Project No ) 1.0 INTRODUCTION This report presents the results of Phase II Environmental Site Assessment (ESA) activities conducted by Fugro West, Inc., (Fugro) at th Avenue in Oakland California (Site). The Site comprises approximately seven acres of a sixteen acre property currently owned by AC Transit. This ESA was conducted on behalf of the City Of Oakland Environmental Services Division (City), which received funding from a USEPA Brownfield Grant (Assistance ID No. BF ). The City has indicated that the Site will be redeveloped as a commercial property with a grocery store and a strip mall. This investigation was conducted based on data gaps identified after review of recent Phase I and II ESAs conducted by others and was completed in accordance with Fugro s Sampling and Analysis Plan (SAP) dated May The City of Oakland was given permission by the United States Environmental Protection Agency to implement the SAP while the document was undergoing review. As described in the SAP, historical site uses included the use of the property by a fruit cannery from 1929 through 1971, a trucking company, a roofing supply company, a bakery, and other commercial uses. In addition, a railroad spur is located onsite. Previous Phase I and II ESAs conducted by Geomatrix (Geomatrix 2006) and Bureau Veritas (Bureau Veritas 2008) identified detectable concentrations of metals, petroleum hydrocarbons, and chlorinated solvents in the soil, groundwater, and/or soil-gas on the property. Fugro s review of these documents identified the following data gaps that required further investigation: Limited investigation was conducted at the railroad spurs located along the western and southwestern Site boundaries. Limited investigation of the shallow soil and groundwater beneath existing and former warehouses, including Warehouse J, the Bimbo s Bakery warehouse, Warehouse I, the roofing supply warehouse, and the former cannery building on the southwestern portion of the Site. An Underground Storage Tank (UST) was removed in 1994 from the south side of Warehouse J near 66th Avenue. The recent Phase II ESAs identified elevated concentrations of Total Petroleum Hydrocarbons as gasoline and diesel (TPHg and TPHd) at 3,300 micrograms per liter (µg/l) and 1,200 µg/l, respectively, in grab groundwater obtained from Boring BV-15 located at the former UST location. Additionally, aromatic hydrocarbons within the benzene family (n-butylbenzene, sec- Butylbenzene, tert-butylbenzene, etc.) were also detected in the grab groundwater sample. No borings were advanced downgradient of this location to evaluate the lateral extent of contamination. Elevated volatile organic compounds (VOCs), specifically tetrachloroethene, were detected in a grab groundwater sample obtained from Boring SB-30, located near the northern Site boundary. Areas along the northern boundary were not evaluated for the presence of VOCs in the groundwater as a result of upgradient industrial activities. G:\JOBDOCS\272\ AC TRANSIT\FINAL DOCS\RPT JULY09.DOC 1

10 U.S. Environmental Protection Agency July 2009 (Project No ) In 2008, Bureau Veritas conducted a limited assessment of suspect asbestos containing materials (ACM) in readily accessible spaces in Warehouse I and J. Based on their observations, suspect ACM is present in various areas of both warehouses. No samples of the suspect ACM was collected during their inspection. Accordingly, a complete ACM and lead-based paint survey (LBP) has not been conducted at the Site. The purpose of this Phase II ESA was to evaluate existing shallow soil, groundwater, and soil-gas conditions; to determine whether hazardous materials from historical operations have impacted the Site; evaluate the potential for impacts from offsite sources; evaluate whether metals are present within the shallow fill/soil; and, if contaminants are present, evaluate whether detected contaminants represent a significant risk to current and/or anticipated future Site users, including construction workers and commercial users at the planned development. Results of this report will be used to assist the City with their redevelopment plans. The City has indicated that the Site will be redeveloped as a commercial property with a grocery store and a strip mall. However, this ESA will utilize the most conservative approach and will therefore compare detected soil, groundwater, and soil-gas concentrations with residential land use screening levels. 2.0 LIMITATIONS Fugro has prepared this report in a professional manner, using that degree of skill and care exercised for similar projects under similar conditions by reputable and competent environmental consultants.

The Site is situated in a mixed residential and commercial land use area, bordered by 66 th Avenue to the southeast, the Union Pacific Railroad Right-of-Way (ROW), elevated BART tracks, and San Leandro Street to the southwest, the AC Transit District Facility to the northwest, and improved industrial properties to the northeast. G:\JOBDOCS\272\ AC TRANSIT\FINAL DOCS\RPT JULY09.DOC 2

11 U.S. Environmental Protection Agency July 2009 (Project No ) The Site is situated approximately 0.6 miles east of San Leandro Bay and is located within the Coliseum BART Redevelopment Area. The Site currently consists of two large occupied warehouses. Parking areas are located adjacent to each of the warehouses. A large portion of the Site is also occupied by the foundation of a former cannery building and a water tower. The former cannery area is currently used to store roofing materials and vehicles. Additionally, rail spurs are located adjacent to the northwestern and southwestern boundaries of the Site. The area between the building pads comprises asphalt paving except for the railroad tracks, which are not paved, and contain significant growth of grass and weeds. Elevation at the Site varies, ranging from 6.0 to feet above mean sea level, due to the presence of approximately five feet of fill beneath the former cannery building. 4.0 HISTORICAL SITE USE AND RECOGNIZED ENVIRONMENTAL CONDITIONS Phase I and II ESAs were recently conducted by Geomatrix and Bureau Veritas from 2006 through Based on information obtained from the Phase I ESAs, the Site reportedly was used as a fruit cannery from 1929 to 1971 (Fruitvale Canning Company). From 1971 to 1980, the Site warehoused canned fruit. The Fruitvale Canning Company also reportedly operated boilers, a laboratory, a fumigation room, a machine shop, an oil house, and a maintenance shop during its time of operation at the Site. Three buildings were located onsite, two of which are still present. Warehouse I is located at the north side of the property and was constructed in Reportedly a cannery building was located at the southern corner of the Site, and was also constructed in Warehouse J is located on the east side of the property and was constructed in the 1980 s. A 1,500 gallon fuel UST was removed from the southeastern edge of the Site near Warehouse J, and 66 th Avenue. This removal occurred in October 1994 under guidance from Alameda County Environmental Health (ACEH). One hole was observed at the bottom of the UST during removal. Approximately 30 cubic yards of petroleum impacted soil was excavated during the UST removal. ACEH issued a no further action letter in December A trucking company reportedly operated at Warehouse I until 1993, and chemicals reportedly stored included Freon 21 (R21), waste oil, motor oil, and propane. Inspection by ACEH in 1992 identified the storage of drums of waste oil and used oil filters, and batteries. This building is currently occupied by Roofing Supply of Oakland and roofing materials and supplies (cements, coatings, tar, shingles, etc.) are currently stored inside. Warehouse J is currently occupied by Bimbo Bakeries USA and a non-chemical dry cleaning supplier. This building is primarily used as a distribution center for each business. The southern and western portions of the Site contain a concrete foundation from the former cannery, a former railroad spur, and a water tower in disrepair. The former cannery area is currently used by Roofing Supply of Oakland to store extra roofing materials and vehicles. The railroad spur continues along the western side of the property, adjacent to Warehouse I. Concrete-lined sumps are present within the loading docks of the two warehouse buildings. G:\JOBDOCS\272\ AC TRANSIT\FINAL DOCS\RPT JULY09.DOC 3

12 U.S. Environmental Protection Agency July 2009 (Project No ) The Phase II ESAs identified low concentrations of polycyclic aromatic hydrocarbons (PAHs) and heavy metals in the subsurface soil along the railroad spurs. Select metals were detected above their respective Environmental Screening Levels (ESLs) in shallow soil in various borings, including arsenic, cobalt, lead, and nickel. Additionally, low concentrations of total petroleum hydrocarbons as gasoline, diesel, and motor oil (TPHg, TPHd, and TPHmo) were also detected in soil samples collected from various locations across the Site. Analysis detected 270 milligrams per kilogram (mg/kg) of TPHd in soil at a depth of 9.0 feet near the former oil house (southwest of Warehouse I, near the railroad spurs and water tower). Groundwater samples from the former oil house and boiler room area contained elevated concentrations of TPHg (up to 260 µg/l), TPHd (up to 790 µg/l), and MTBE (up to 130 µg/l), that exceeded their respective ESL criteria. Elevated TPHg and TPHd concentrations (3,300 µg/l and 1,200 µg/l, respectively) and aromatic hydrocarbons within the benzene family (n-butylbenzene, sec-butylbenzene, tert-butylbenzene, etc.) were also detected in groundwater collected near the former UST location, southwest of Warehouse J, near 66 th Avenue. Further, chlorinated solvents, specifically tetrachloroethene (PCE), were identified in groundwater samples obtained from the location of the former maintenance shop. Soil-gas samples obtained from this area identified elevated concentrations of chloroform at 500 micrograms per cubic meter (µg/m 3 ), above the residential ESL of 460 µg/m 3. In 2008, Bureau Veritas conducted a limited visual assessment of the structures onsite as part of a larger visual assessment of the sixteen acre AC Transit Property. Bureau Veritas conducted their non-invasive assessment of readily accessible areas in Warehouses I and J. Their assessment identified the presence of suspect ACMs in various items including, ceiling panels, floor tiles, gypsum board, mastics, flooring, and exterior paint. According to their report, the suspect ACMs appeared to be in good condition. No samples were obtained during the assessment to confirm the presence of asbestos within the buildings. A copy of Bureau Veritas limited assessment report is presented in Appendix D. During our reconnaissance of the property on April 23, 2009, Fugro observed the presence of transite pipe stockpiled beneath the water tower. Accordingly, transite pipe may be located in areas not observed during out reconnaissance, such as hidden inside the warehouses or located underground. 5.0 SITE ASSESSMENT ACTIVITIES Fugro conducted this soil, groundwater, and soil-gas investigation in general conformance with the SAP dated May DEVIATIONS FROM THE SAP Deviations from the SAP include the following: A grab groundwater sample was obtained from the perched water located at Boring SG-1 and analyzed for VOCs. G:\JOBDOCS\272\ AC TRANSIT\FINAL DOCS\RPT JULY09.DOC 4

13 U.S. Environmental Protection Agency July 2009 (Project No ) Grab groundwater sampling was conducted over a two-day period; therefore a second equipment blank was obtained during the field activities. Groundwater was not encountered in Boring B-7; therefore no grab groundwater sample was obtained from this location. 5.2 SAMPLING ACTIVITIES Fugro s Site assessment activities focused on evaluating existing soil, groundwater, and soil-gas conditions to determine whether hazardous materials are present and, if so, whether they represent a significant risk to current and/or anticipated Site users, including construction workers, commercial, and residential users. In general, soil assessment focused on the presence of metals, VOCs, and petroleum hydrocarbons in surface and near-surface soil that may be excavated during redevelopment activities. Groundwater assessment activities focused on evaluating VOCs and petroleum hydrocarbon concentrations at the Site. Soil-gas sampling activities focused on evaluating VOC concentrations near the location of the former oil houses. Prior to commencement of fieldwork, Fugro obtained a drilling permit from Alameda County Public Works Agency (ACPWA). A copy of the permit is presented in Appendix A. Fugro also retained a private utility locator to clear all proposed sampling locations and alerted the Underground Service Alert (USA) at least 48 hours prior to intrusive field activities. During our reconnaissance of the property on April 23, 2009, Fugro observed a metallic cap residing within the concrete pad near the former oil houses located northwest of the existing water tower. During our private utility survey, Fugro attempted to remove the cap. Our field geologist indicated that the cap appeared to be under pressure and that the emanating gas had a strong gasoline odor. Due to health and safety concerns, Fugro did not completely remove the cap at that time, and recommended conducting a geophysical survey to evaluate this underground feature. On June 1, 2009, a geophysical survey was conducted within this area as further discussed in Section 9.0 of this report. Drilling activities were conducted on May 18 through 20, 2009, using standard industry practices regarding worker health and safety. RSI Drilling, a State of California licensed drilling contractor, conducted drilling activities at the Site using direct push drilling methods. Fieldwork included the completion of fourteen direct push borings (B-1 through B-14) to a maximum depth of 20 feet bgs and two soil-gas borings (SG-1 and SG-2) to a depth of 5.0 feet bgs. Boring locations are presented on Plate 2. Drilling and sampling activities were conducted under the supervision of Fugro s field personnel. Fugro s field geologist logged each boring in accordance with the Unified Soil Classification System (USCS) and screened soil samples in the field using an Organic Vapor Meter (OVM). Discrete soil samples were collected from a variety of depths from each boring depending on field sample recovery. In general, soil samples were collected from 1.0, 2.0, 5.0, 7.5, and feet bgs within the direct push borings. Groundwater at the Site was encountered at depths ranging from 2.1 to.5 feet bgs. All borings were completed to depths ranging from 16 feet to 20 feet bgs. Grab groundwater G:\JOBDOCS\272\ AC TRANSIT\FINAL DOCS\RPT JULY09.DOC 5

14 U.S. Environmental Protection Agency July 2009 (Project No ) samples were collected from Borings B-2 through B-6, B-8, and B-12 through B-14. Groundwater was not encountered in Boring B-7. At Boring locations B-2 through B-6, and B-12, clean PVC casing was placed in each boring to facilitate grab groundwater sample collection. Samples were collected using clean disposable bailers and decanted into pre-cleaned laboratory provided bottles. At Borings B-8, B-13, and B-14, investigation activities focused on potential groundwater impacts from hydrocarbons. Accordingly, pre-packed well screens were used instead of PVC casing to reduce the turbidity of the grab groundwater samples and potential matrix interference during chemical analyses. Samples from these borings were collected using a peristaltic pump with disposable tubing and decanted into pre-cleaned laboratory provided bottles. PVC casing and the pre-packed well screens were removed once the grab groundwater samples were collected. Upon completion, all borings were backfilled with neat cement grout and restored to existing conditions. Soil cuttings were placed in Department of Transportation-approved and labeled 55-gallon drums, which were stored onsite, pending chemical classification and offsite disposal. 6.0 CHEMICAL TESTING PROGRAM Soil and groundwater samples were immediately stored in ice-chilled coolers. Soil-gas samples were collected in 6 Liter Summa canisters, stored in their original cardboard packaging pending submittal to the laboratory. Upon completion of field activities all samples were transported under chain-of-custody documentation to Torrent Laboratories, a State of California-certified testing laboratory. Results of chemical analyses are discussed in Section SOIL SAMPLES A total of twenty-eight soil samples were submitted for chemical analyses, not including three duplicate soil samples. In accordance with our SAP, samples were analyzed for some or all of the following: TPHg using EPA Method 8015m; TPHd and TPHmo using EPA Method 8015m with silica gel cleanup; PAHs using EPA Method 8270; VOCs using EPA Method 5035/8260; 17 Title 22 metals using EPA Methods 60/7000 series; Total Arsenic using EPA Method 60/7000; and/or Total Lead using EPA Method 60/ GROUNDWATER SAMPLES A total of nine grab groundwater samples were submitted for chemical analysis, not including two duplicate samples, two equipment blank (rinsate) samples, and one trip blank sample collected for QA/QC purposes. The grab groundwater samples were analyzed for some or all of the following: G:\JOBDOCS\272\ AC TRANSIT\FINAL DOCS\RPT JULY09.DOC 6

15 U.S. Environmental Protection Agency July 2009 (Project No ) VOCs using EPA Method TPHg using EPA Method 8015m; and/or TPHd and TPHmo using EPA Method 8015m with silica gel cleanup. 6.3 SOIL-GAS SAMPLES A total of two soil-gas samples were submitted for chemical analysis, not including one duplicate sample and one trip blank sample collected for QA/QC purposes. The soil-gas samples were analyzed for the following: VOCs using EPA Method TO FIELD QUALITY CONTROL SAMPLES Fugro implemented QA/QC procedures during this field investigation in accordance with the SAP. Three duplicate soil samples were collected and analyzed as quality control samples in accordance with the SAP. Two duplicate groundwater samples were also collected and analyzed as quality control samples in accordance with the SAP. Two equipment blank (rinsate) samples were collected to ensure that there was no cross contamination between borings from the electronic water level sounder. Fugro also tested one trip blank sample for VOCs to confirm that no sample contamination occurred during sample transport. The trip blank sample was submitted along with grab groundwater samples that were collected during drilling activities. One duplicate soil-gas sample was collected and analyzed as quality control in accordance with the SAP. One soil-gas trip blank sample was tested for VOCs to confirm that sample contamination did not occur during transport. The soil-gas trip blank sample was submitted with the soil-gas sample obtained during this investigation. 7.0 SUBSURFACE CONDITIONS Subsurface conditions generally comprised alternating layers of firm to stiff, dark brown to light grayish brown lean clay to lean clay with sand to the maximum depth explored of 20 feet. Fill consisting of clayey, gravelly silt with sand was only encountered in Borings B-9 through B- 14 at depths ranging from 1.0 to 5.5 feet bgs. Fugro s field geologist screened soil samples in the field using an OVM. No hydrocarbon or solvent odors were encountered in any of the soil samples screened. Sample yielded the highest OVM reading of 1.9 ppm. Fugro did not observe the presence of vapor barriers in any of the borings completed within the building footprints. Logs of borings are presented in Appendix B. Depth to groundwater ranged fro 2.1 to.5 feet bgs when encountered. No odors or free phase hydrocarbons were detected or observed in any of the grab groundwater samples collected. G:\JOBDOCS\272\ AC TRANSIT\FINAL DOCS\RPT JULY09.DOC 7

16 U.S. Environmental Protection Agency July 2009 (Project No ) 8.0 RESULTS OF ANALYSES This Section presents results of analyses, including a discussion of the data validation and QA/QC program as well as summaries, and findings of the soil and groundwater sampling. As described in the SAP, results of analyses were compared to ESLs established by the San Francisco Bay Regional Water Quality Control Board (RWQCB). 8.1 QUALITY CONTROL AND DATA VALIDATION Fugro implemented QA/QC and conducted data validation in accordance with the SAP. The objectives of the QA/QC and data validation were to obtain and present accurate, precise, and complete data. Based on our review of the overall field and laboratory QA/QC protocols, data validation and findings, Fugro judges that soil and groundwater sampling conformed with the objectives stated in the SAP, and that the samples and resulting chemical analyses are representative of site conditions. Soil-gas samples collected at the Site were compromised due to the presence of leak check compound in SG-2 and the presence of perched groundwater observed at SG-1. Laboratory and field QC sampling and analyses are discussed below Laboratory QA/QC Samples To assess the accuracy of the laboratory data, Fugro reviewed the laboratory reports to confirm compliance with the laboratory s own QA/QC limits. For the soil and groundwater samples, Torrent s QA/QC reports indicated no exceptions to compliance with their own QA/QC limits. In general, Torrent noted no QA/QC problems for EPA Methods. Certain analytes in both soil and water had minimum detection limits above the Data Quality Indicators (DQIs). For soil these analytes are: benzene, ethylbenzene, toluene, methyl tert-butyl ether (MTBE), naphthalene, tetrachloroethene, trichloroethene, and xylene. While the detection limit for these analytes was above their respective DQI, the detection limits were below their respective direct exposure ESL for residential land use, and are therefore acceptable for the purposes of this Phase II ESA. For groundwater the following analytes had a detection limit in excess of the EPA DQI: xylenes and total petroleum hydrocarbons as diesel. While the detection limit of these analytes is above their respective EPA DQI, their detection limit is below their respective ESLs and are therefore still acceptable for the purposes of this Phase II ESA. Analysis detected acetone in the trip blank at a concentration of 2.9 µg/m 3. The source of the detected acetone is unknown at this time; however, discussions with Torrent Laboratory indicate that acetone is used in their lab. The Summa canisters used during the soil-gas investigation were part of laboratory batch certified; therefore the detection could possibly be attributed to residual laboratory contamination within the canister. If additional soil-gas sampling is conducted at the Site, each Summa canister should include individual laboratory certification. To assess the completeness of the data, Fugro checked 0 percent of the laboratory reports for soil, groundwater, and soil-gas samples, and found that all requested tests were completed. Therefore, the chemical reports are considered to be complete. G:\JOBDOCS\272\ AC TRANSIT\FINAL DOCS\RPT JULY09.DOC 8

17 U.S. Environmental Protection Agency July 2009 (Project No ) Field Quality Control Samples To assess field procedures and laboratory accuracy, Fugro collected one duplicate groundwater sample and six duplicate soil samples. Analysis of the duplicate groundwater sample (DB-2) detected TPHd and TPHmo concentrations with a relative percent difference (RPD) of 11.3 percent. Two equipment blank (rinsate) samples were tested for TPHg, TPHd, TPHmo, and VOCs during this investigation. None of the analytes were detected indicating that there was no cross contamination between borings from the electronic water level sounder. Fugro also tested one trip blank sample for VOCs during this investigation. The sample was submitted on May 21, 2009 along with grab groundwater samples that were collected during drilling activities at the Site. Results of chemical analysis detected no VOCs in the trip blank, confirming that samples were not contaminated during sample transport. Results of the field quality control samples are also presented in Table 1. Duplicate groundwater results were within acceptable RPD criteria of 20 percent. However, the RPD for soil ranged from 6.9 to 75.9 percent, exceeding the RPD criteria of 50 percent in two of the seven analytes. The duplicate soil samples were obtained from fill material at the Site, and although the samples were homogenized in the field, the large RPD is most likely a result of the non-homogeneous nature of the fill. This finding is consistent with Fugro s experience regarding fill at similar sites in the Bay Area. As a result, the high RPD of the soil samples is not considered significant. The RPD for soil-gas ranged from 47.9 to 94.3 percent, exceeding the RPD criteria of 35 percent in all analytes tested. The large RPD values are attributed to the presence of perched water within the sampling tube. Fugro utilized isopropyl alcohol in the field as a leak check compound. Analysis detected ispropanol at a concentration of 1,400 µg/m 3 in Sample SG-2, indicating that some ambient air was able to permeate through the sampling train. As previously stated, one trip blank was also tested for VOCs to confirm whether samples were contaminated during transport. Analysis detected acetone at a concentration of 2.9 µg/m 3. Its presence is attributed to residual laboratory contamination within the sample canister. Based on analytical results, Fugro concludes that the soil-gas investigation is not considered valid for the purposes of this Phase II ESA. 8.2 RESULTS OF CHEMICAL ANALYSIS SOIL Analytical reports from Torrent Laboratories are presented in Appendix C. Results of chemical analyses for soil samples are summarized in Table 2 and are discussed below. No VOCs or PAHs were detected in any of the samples tested. TPHg was detected in two of the thirty-one samples analyzed at concentrations ranging from 0.14 mg/kg to 0.21 mg/kg, well below the ESL of 1 mg/kg for residential land use. TPHd was detected in one of the thirty-one samples analyzed at a concentration of 4.24 mg/kg, below the residential land use ESL of 1 mg/kg. Additionally TPHmo was detected in seven of the thirty-one samples analyzed at concentrations ranging from 5.0 mg/kg to 2,0 mg/kg, exceeding the residential G:\JOBDOCS\272\ AC TRANSIT\FINAL DOCS\RPT JULY09.DOC 9

18 U.S. Environmental Protection Agency July 2009 (Project No ) land use ESL of 370 mg/kg in Sample This sample was collected within the shallow fill below the former cannery warehouse. All detected metals concentrations are below their respective TTLCs, one of the criteria for classifying soil as hazardous waste. Except for detected concentrations of arsenic in twentynine of thirty-one samples analyzed, all detected metals are below their respective ESLs for residential land use. Ambient background concentrations of arsenic in California soil typically exceed the residential land use ESL of 0.39 mg/kg. Numerous studies have been conducted to establish a range of values (up to mg/kg) that represent background arsenic values. The range of detected arsenic concentrations is 1.7 mg/kg to 12 mg/kg. As a result, it is our opinion that arsenic values at the Site represent background concentrations. 8.3 RESULTS OF CHEMICAL ANALYSIS GROUNDWATER Results of chemical analysis conducted for groundwater samples during this investigation are summarized in Table 3 and are discussed below. No TPHg, TPHd, or TPHmo were detected in any of the grab groundwater samples analyzed. Analysis detected VOCs in three out of eleven groundwater samples, including 1,2- dichloropropane which was detected in Boring B-4 at a concentration of 31 µg/l, above the maximum contaminant level (MCL) of 5.0 µg/l. Trichlorofluoromethane was detected at a concentration of 0.59 µg/l in Boring B-2, no MCL has been established for this analyte. Additionally, MTBE was detected at 3.7 µg/l in Boring B-12, below the MCL of 5.0 µg/l. The source of the detected VOCs is unknown. Perched water obtained from within soil-gas sample location SG-1 reported low concentrations of various VOCs including ethylbenzene (0.60 µg/l), toluene (0.64 µg/l), total xylenes (3.7 µg/l), naphthalene (1.1 µg/l), 1,2,4-trimethylbenzene (0.65 µg/l), and 1,3,5- trimethylbenzene (1.9 µg/l). Most of the detected VOCs were below their respective ESLs, with the exception of 1,2,4-trimethylbenzene and 1,3,5-trimethylbenzene since no ESLs have been established for these compounds. 8.4 RESULTS OF CHEMICAL ANALYSIS SOIL-GAS SAMPLES Results of chemical analysis conducted for soil-gas samples during this investigation are summarized in Table 4 and are discussed below. Based on our review of the QC data (detection of leak check compound, trip blank, and elevated RPDs) soil-gas data is considered invalid for the purposed of the Phase II ESA but are reported herein for completeness. Analysis detected various VOCs in all samples analyzed including ethylbenzene (ranging from 61 µg/m 3 to 130 µg/m 3 ), toluene (ranging from 84 µg/m 3 to 160 µg/m 3 ), total xylenes (ranging from 430 µg/m 3 to 870 µg/m 3 ), 4-Ethyl Toluene (ranging from 46 µg/m 3 to 74 µg/m 3 ), 1,2,4-trimethylbenzene (ranging from 86 µg/m 3 to 120 µg/m 3 ), and 1,3,5- trimethylbenzene (ranging from 46 µg/m 3 to 75 µg/m 3 ). Analysis also detected 2-Hexanone in Sample DSG-1 at a concentration of 7.8 µg/m 3. Benzene, acetone, and t-butyl alcohol were detected in Sample SG-2 at concentrations of 11 µg/m 3, 27 µg/m 3, and 2.9 µg/m 3, respectively. G:\JOBDOCS\272\ AC TRANSIT\FINAL DOCS\RPT JULY09.DOC

19 U.S. Environmental Protection Agency July 2009 (Project No ) All VOCs were detected below their respective shallow soil-gas ESL. We note that no ESLs have been established for 4-Ethyl Toluene, 2-Hexanone, t-butyl alcohol, 1,2,4-trimethylbenzene, and 1,3,5-trimethylbenzene. Most of the VOCs detected in the soil-gas samples are the same as the analytes detected in the perched water at SG-1 as discussed above. The source of the other VOCs detected in soil-gas (benzene, acetone, 2-Hexanone) is unknown. 9.0 GEOPHYSICAL SURVEY Fugro subcontracted with NORCAL Geophysical Consulting Inc. (NORCAL) to conduct a geophysical survey of the area around the metal cap observed residing within the concrete pad near the former oil houses, northwest of the existing water tower The purpose of the survey was to determine whether a UST or piping was present in this area, as well as the extent and orientation of the underground feature. For this survey, NORCAL used some or all of the following field methods: Ground Penetrating Radar (GPR), Metal Detection (MD), and/or Electromagnetic Line Locating (EMLL). The use of these methods was based on conditions within the survey area, including the presence of rebar in the concrete. The GPR method was used to image variations in the electrical properties of the shallow subsurface. These variations can provide information regarding the locations and dimensions of a UST. The MD method was used to detect shallow subsurface metal objects that may represent a UST and the EMLL method was used to locate detectable utility alignments. Results of the geophysical survey using GPR and MD methodologies did not detect a large subsurface object that can be interpreted as a UST. The EMLL survey did identify the presence of an undifferentiated utility alignment. This alignment trends south from the metal cap to a large shrub located adjacent to the water tower. NORCAL did not identify the presence of the alignment on the south side of the shrub therefore NORCAL indicated that the utility line most likely terminates beneath the vegetation. The utility line most likely is associated with the UST and piping associated with the existing water tower. A copy of NORCAL s report is presented in Appendix E..0 REMEDIAL EVALUATION Based on the results of this investigation, coupled with results from the previous Phase II ESAs conducted by Geomatrix and Bureau Veritas, it appears that there are four localized areas where soil concentrations exceed commercial land use ESLs for certain metals and/or petroleum hydrocarbons. These locations include the following Geomatrix Boring SB-06, located along the northeastern property boundary, between Warehouses I and J, Geomatrix Boring SB-07, located on the northeastern side of Warehouse I, Geomatrix Boring SB-34, located within the footprint of the former cannery building, and G:\JOBDOCS\272\ AC TRANSIT\FINAL DOCS\RPT JULY09.DOC 11

20 U.S. Environmental Protection Agency July 2009 (Project No ) Bureau Veritas Boring BV-25, located near the former oil houses. In Fugro s opinion, the presence of these contaminants is most likely limited to the upper two feet of shallow soil in these areas. Our initial estimates indicate that approximately 150 cubic yards of soil may be impacted with elevated metals and/or petroleum hydrocarbons. Please note that the actual extent of contaminated fill is not known at this time. Assuming a reasonably limited impact at each location (20 feet by 20 feet by 2 feet deep), preliminary estimates to remediate the four areas range from $30,000 to $35,000. The railroad ties located along the railroad spurs on the western and southern Site boundaries should be disposed as treated wood at an accepting Class II facility. A preliminary estimate to dispose of the ties ranges from $,000 to $15,000. This estimate is for disposal only and does not include costs associated with removing the railroad from the Site. The UST beneath the water tower, as well as the associated piping and undifferentiated utility alignment may also require special handling. Based on field observations, that area may include some localized hydrocarbon impacts to soil and/or perched water. Estimates to remove the UST, piping, and utility alignment could range from $35,000 to $65,000. Based on the costs outlined above, remediation costs range from $90,000 to $138,000, which includes a 20% contingency to account for any unforeseen conditions that may arise during redevelopment. Please note that this estimate is not a bid. Fugro subcontracted SCA Environmental Inc. (SCA) to review the Limited Assessment of Suspected Asbestos-Containing Materials Report prepared by Bureau Veritas. Based on the visual observations of suspected ACMs identified in the report, SCA estimates that the total abatement costs is $260,000 which includes a 20% contingency. This estimate is in addition to the remedial estimate listed above and assumes all suspect materials are verified as asbestos containing. Actual abatement costs of other materials that may be present at the Site, such as transite, roofing materials, and vapor barriers, may be significantly greater than $260,000. Estimates to remediate groundwater at the Site were not included in this evaluation. However, based on the presence of elevated TPHg and TPHd in groundwater at location of the former UST adjacent to Warehouse J and 66 th Avenue, as well as the presence of MTBE, TPHg and TPHd in groundwater at the location of the former boiler room, a vapor barrier should be included in the construction design to mitigate any potential vapor intrusion concerns CONCLUSIONS Fugro concludes that the site investigation was completed in general conformance with the SAP. In our opinion, with the exception of the soil-gas results, the resulting findings adequately characterize site conditions. The following summarizes our conclusions.

21 U.S. Environmental Protection Agency July 2009 (Project No ) 11.1 SUBSURFACE CONDITIONS Subsurface conditions generally comprised alternating layers of firm to stiff, dark brown to light grayish brown lean clay to lean clay with sand to the maximum depth explored of 20 feet. Overlying the lean clay in Borings B-9 through B-14, fill material consisting of clayey, gravelly silt with sand was encountered at depths ranging from 1.0 to 5.5 feet bgs. Fugro s field geologist screened soil samples in the field using an OVM. No hydrocarbon or solvent odors were encountered in any of the soil samples screened. Sample yielded the highest OVM reading of 1.9 ppm. Fugro did not observe the presence of any Depth to groundwater ranged fro 2.1 to.5 feet bgs when encountered. No odors or free phase hydrocarbons were detected or observed in any of the grab groundwater samples collected CHEMICAL FINDINGS For soil, no VOCs or PAHs were detected in any of the five samples tested. TPHg was detected in two of the thirty-one samples analyzed and TPHd was detected in one of the thirtyone samples analyzed. Detected TPHg and TPHd concentrations were well below their respective ESLs of 0 mg/kg for residential land use. Additionally, TPHmo was detected in seven of the thirty-one samples analyzed, one sample (B-12@1 ) contained 2,0 mg/kg, which exceeded the residential land use ESL of 370 mg/kg. This sample was collected within the shallow fill below the former cannery warehouse. All detected metals concentrations in soil are below their respective TTLCs, one of the criteria for classifying soil as hazardous waste. Except for detected concentrations of arsenic, all detected metals are below their respective ESLs for residential land use. Detected arsenic concentrations ranged from 1.7 mg/kg to 12 mg/kg, and are consistent with naturally occurring background values. For groundwater, no petroleum hydrocarbons were detected in any of the grab groundwater samples analyzed. Analysis detected relatively low VOCs in three out of eleven groundwater samples, of which 31 µg/l of 1,2-dichloropropane (B-4) was the only VOC detected that exceeded its respective ESL of 5.0 µg/l. The source of the detected VOCs is unknown RECOMMENDATIONS Fugro recommends no further subsurface investigation at this time. Bureau Veritas observed suspect ACMs during their limited assessment in No samples were collected at that time, therefore Fugro recommends that a complete ACM and LBP survey be conducted prior to demolition or renovation of the existing structures to confirm the presence of ACM and further refine abatement costs if needed. Results of the building material survey should be used to confirm ACM and LBP abatement costs. We recommend that development plans should incorporate standard dust control measures during construction to reduce the nuisance exposure to construction workers and the G:\JOBDOCS\272\ AC TRANSIT\FINAL DOCS\RPT JULY09.DOC 13

22 U.S. Environmental Protection Agency July 2009 (Project No ) general public during soil handling activities. Copies of this report should be provided to the Contractor performing construction at the Site. Based on results of analyses and our experience at similar sites with similar conditions, soil excavated from the Site will most likely be considered a non-hazardous waste and will be suitable for disposal at a Class II or Class III landfill. However, based on the presence of localized areas of hydrocarbon and/or metal contamination in shallow soil, and because concentrations exceeded their respective commercial ESLs, additional testing may be required by the receiving party. If staining, chemical odors, underground storage tanks (USTs), or other signs of contamination and/or contaminated material are encountered during construction, the contractor should notify the City of those conditions and appropriate precautions, investigation, and/or mitigation should be implemented. If proposed redevelopment involves dewatering and/or groundwater handling, appropriate planning, permitting, and likely treatment of that groundwater will be required prior to discharge. Any dewatering planned for the Site should consider the presence of VOCs and TPH in groundwater REFERENCES ASTM Designation E (2002), Standard Guide for Environmental Site Assessments: Phase II Environmental Site Assessment Process, dated 1997, and reviewed and found to be still relevant in 2002 by ASTM.

No corrective action is required. Analytical Comment for METHOD PAH_S, Note:The % recoveries for surrogates are outside of laboratory control limits (high bias). All samples were Non Detect for those compounds associated with the surrogate.s The high bias recoveries will be considered in the next control chart update. No corrective action is required. REVISIONS: Athough the samples requested 8260B_S and 8260B_W analysis, Note: Although the samples were analyzed for full ist 8260Bcompounds, due to a laboratory LIMS failure, no 1,1-DCA appeared on the originally submitted data. The report has been re-issued to include 1,1-DCA. The associated QC has been re-validated and re-issued. Rev 1 (6/8/09) Page 1 of 1

193 Torrent Laboratory, Inc. CLIENT: Project: Lab Order: Date: 08-Jun-09 CASE NARRATIVE Analytical Comments for METHOD TO-15 ug/m3, SAMPLE A: Note: Per client request, sample data and associated QC was reviewed due to the trace level of Acetone found in the Trip Blank sample. After a thorough review of the associated instrument and method blanks, the probability of laboratory contamination from Acetone is low. However, Acetone is a compound in common laboratory use and though the probability of contamination is low, the possibility of laboratory contamination can not be fully discounted.

211 APPENDIX D BUREAU VERITAS, LIMITED ASSESSMENT OF SUSPECT ASBESTOS-CONTAINING MATERIALS, DATED JUNE 11, 2009

212 June 11, 2009 Mr. Robert Soran DOWNEY BRAND, LLP 555 Capitol Mall, th Floor Sacramento, California Project No Subject: Limited Assessment of Suspect Asbestos-Containing Materials at th Avenue in Oakland, California Dear Mr. Soran: Bureau Veritas North America, Inc. (Bureau Veritas) is pleased to submit our report on the limited assessment of suspect asbestos-containing materials (ACM) at the above-noted buildings. This assessment was limited to a visual assessment for suspect ACM and sampling and analysis of damaged suspect ACM. The scope of services provided by Bureau Veritas was described in our proposal no R2 dated May 19, 2008, which included an explanation of the terms and conditions under which Bureau Veritas services were provided. In addition, according to your request dated May 31, 2009, this report covers buildings associated with land identified as Oakland Redevelopment Agency (ORA) Area of Interest, which were initially described in our report regarding a larger area dated May 23, This limited assessment was conducted by Mr. Joe Rajan, CIH, CSP and California Certified Asbestos Consultant (# ), and Mr. Tim Coe, California Certified Asbestos Consultant (# ) on May 20, Bureau Veritas inspected for suspect ACM in the following buildings/spaces: 915, , and th Avenue. Bureau Veritas looked for suspect ACM in readily accessible areas of the buildings/spaces. The condition of the suspect ACM was also noted. Bureau Veritas did not collect samples of suspect ACM that were in good condition. Based upon the condition of suspect ACM in the buildings, no samples of suspect ACM were collected. More detailed descriptions of the suspect ACM identified during this assessment are presented in the tables provided as Attachment 1. The building/space numbers and locations are provided in the drawing included as Attachment 2. Bureau Veritas North America, Inc. Health, Safety, and Environmental Services 2430 Camino Ramon, Suite 122 San Ramon, CA Main: (925) Fax: (925)

213 Mr. Robert Soran Page 2 DOWNEY BRAND, LLC June 11, 2009 Project No Recommendations Based on the findings of this assessment, Bureau Veritas recommends the following: Suspect ACM identified but not sampled in these buildings/spaces were observed to be in good condition, and should be assumed to contain asbestos in detectable quantities until appropriate sampling indicates otherwise. These materials may be maintained in-place. Removal of ACM is not required, except prior to renovation activities that may potentially impact the ACM or prior to building demolition. However, any future work activities (e.g., routine maintenance and repair) that involve disturbance to ACM must be performed only by properly trained and protected personnel using appropriate work practices and procedures, and engineering controls, including work area isolation/enclosure. During renovation or demolition, other building materials may be impacted and/or uncovered which were not observed during this survey. These materials should be treated as ACM until sampling and analysis is conducted that indicates otherwise. The findings presented herein must be reviewed giving due regard that the inspection, physical assessment, and sampling procedures contain inherent limitations, as is the case with any sampling procedure, and were conducted based on observations that were visually apparent at the time of the inspection. Thank you for the opportunity to have provided our services. If you have any questions or comments concerning this report, please contact me at (925) Sincerely, Joe Rajan, CIH, CSP Senior Consultant Certified Asbestos Consultant ( ) Health, Safety, and Environmental Services Eric Dueltgen, CIH, PE Senior Project Manager Certified Asbestos Consultant ( ) Health, Safety, and Environmental Services JR/jr Attachment 1: List of Suspect Asbestos Containing Materials Attachment 2: Building/Space Drawing
