The Site is generally located at the southeast corner of Katella Avenue and South Douglass Road in the City of Anaheim, Orange County, California (see Plate 1, Site Location Map). Kleinfelder performed this Limited Preliminary Phase II ESA to assess potential soil impact that may have resulted from the following recognized environmental conditions (RECs) and potential RECs identified in Kleinfelder’s Phase I ESA report of the Site, dated July 17, 2009: Blue-green colored staining was observed on asphalt pavement and concrete, near a dipping vat and within a drainage swale, at the Sullivan & Mann Lumber Company at 1790 South Douglass Road. A gravel-filled pit was observed within a corrugated metal building on the southern portion of the Site parcel with an address of 1750 South Douglass Road. The former use of this pit is unknown to Kleinfelder and previous environmental sampling in this area was not identified by the Phase I ESA. The presence of undocumented fill material was reported in a former quarry on the Site parcel with an address of 1750 South Douglass Road. In addition to the RECs and potential RECs discussed above, Kleinfelder also assessed the following potential areas of concern which we believe warranted further investigation and/or confirmation sampling: An inactive laboratory and a former hazardous materials storage shed are located at 1750 South Douglass Road. In addition, a paint booth was formerly located inside the present-day warehouse building at 1790 South Douglass Road. Paint staining was observed in close proximity to a floor drain at 1750 South Douglass Road, adjacent to a former hazardous materials storage building. ---PAGE BREAK--- 103567-ENV2/LBE9R038 ES - 2 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com The Site parcel at 1750 South Douglass Road also contained a former fueling facility including two 10,000-gallon gasoline underground storage tanks (USTs), one 10,000-gallon diesel UST, two 5,000-gallon diesel USTs, and associated fuel dispensers. These USTs, along with two waste oil USTs (280-gallon and 300-gallon capacity) that were located farther to the east on the Site, were removed in March 1998. The gasoline and diesel USTs were replaced with a 20,000-gallon gasoline UST and a 20,000-gallon diesel UST, which were removed along with associated dispensers in July 2008. Based on Kleinfelder’s review of available Site assessment information, the maximum detected concentrations of benzene, toluene, and total xylenes (BTEX) were in samples from a boring advanced by Tait Environmental Management, Inc. (Tait) to the north of the two former 10,000-gallon gasoline USTs. Soil hydrocarbon impact was also evident in samples from Tait’s Boring which was located by a former dispenser island beneath a presently-existing canopy; and in Boring which was located between the two former 5,000-gallon diesel USTs. Borings B-5 and B-6 are at the locations where Tait reported the highest concentrations of total petroleum hydrocarbons (TPH) from its assessment. Additionally, Block Environmental (Block) reported detected concentrations of total recoverable petroleum hydrocarbons (TRPH) and tetrachloroethylene (PCE) in samples of soil stockpiled from removal of the two former waste oil USTs. The stockpiled soil was subsequently removed from the Site. Three hydraulic lifts and associated equipment and piping were removed from the Site parcel at 1750 South Douglass Road in September and October 2008. A soil sample collected at a depth of approximately 15 feet below grade from a remedial excavation on the north side of former “Hydraulic Lift apparently contained the highest detected TPH concentration in soil not subsequently removed from this area. Four wastewater clarifiers and associated sewer piping were removed from the Site parcel at 1750 South Douglass Road in October 2008. The excavation areas were filled with gravel and not sealed at the surface. ---PAGE BREAK--- 103567-ENV2/LBE9R038 ES - 3 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com Kleinfelder’s scope of services did not include sampling soil within the railroad right of way on the Site or sampling of groundwater beneath the Site. For this reason, although identified as potential RECs in the Phase I ESA report, the following were not addressed as part of this Limited Preliminary Phase II ESA: Former “pouring” of oil along the railroad tracks at/near the Anaheim Stadium Metrolink/Amtrak Station and the potential presence of agricultural chemicals (due to former agricultural land use on surrounding areas from at least 1938 through at least 1952) and heavy metals and creosote (from treated railroad ties associated with the railroad tracks). Potential impacts to Site groundwater resulting from upgradient off-Site facilities where releases are known to, or may, have impacted shallow groundwater. This Limited Preliminary Phase II ESA included performing environmental soil sampling, laboratory analyses, and data evaluation, along with formulation of conclusions and recommendations. A summary of the assessment sampling locations is presented below: Kleinfelder collected environmental soil samples from six geotechnical soil borings (B-1 through B-5 and W-1) that were drilled to depths of approximately 61.5 to 101.5 feet below ground surface (bgs). The environmental samples were collected to a maximum depth of approximately 50 feet bgs. Borings B-1, B-2, and W-1 were sampled as “background” locations based on an absence of identified or suspect environmental concerns within these general areas. (Boring W-1 was subsequently converted into a geotechnical monitoring well.) Boring B-3 was sampled to assess the potential for subsurface contamination in the vicinity of a former hazardous materials storage shed. Borings B-4 and B-5 were sampled to assess the presence of undocumented fill material reported within a former quarry that was in that area of the Site. Kleinfelder submitted the environmental soil samples from these borings to a laboratory, for analysis of TPH with carbon chain identification (TPH-CCID), volatile organic compounds (VOCs) including fuel oxygenates, organochlorine pesticides (OCPs), biphenyls (PCBs), and California Code of Regulations (CCR) ---PAGE BREAK--- 103567-ENV2/LBE9R038 ES - 4 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com Title 22 Metals. These and other analyses discussed below were performed using United States Environmental Protection Agency (US EPA) methodology. Two environmental soil borings (KA-1 and KA-2) were advanced and sampled to a depth of approximately 15 feet bgs in the vicinity of the Sullivan & Mann Lumber Company at the Site’s 1790 South Douglass Road parcel. Boring KA-1 was installed in the location of a former paint booth, and Boring KA-2 was installed within a stained concrete drainage swale near a dipping vat. Soil samples from these borings were submitted to the laboratory for analysis of TPH-CCID, VOCs, and Title 22 Metals. Two environmental soil borings (KA-3 and KA-9) were advanced and sampled to a maximum depth of approximately 10 feet bgs within a former hazardous materials storage shed (Boring KA-3) and in an inactive laboratory (Boring KA-9) located on the Site’s 1750 South Douglass Road parcel. The soil samples from these borings were submitted to the laboratory for analysis of TPH-CCID, VOCs, OCPs, PCBs, and Title 22 Metals. One environmental soil boring (KA-4) was advanced and sampled to a maximum depth of approximately 4.5 feet bgs in the vicinity of a floor drain and nearby paint staining within a bermed area at the 1750 South Douglass Road parcel. Soil samples were submitted to the laboratory for analysis of TPH-CCID, VOCs, OCPs, PCBs, and Title 22 Metals. Four environmental soil borings (KA-5, KA-8, KA-13, and KA-16) were advanced and sampled to a maximum depth of approximately 15 feet bgs at four former wastewater clarifier locations. Soil samples were submitted to the laboratory for analysis of TPH-CCID, VOCs, OCPs, and PCBs. One environmental soil boring (KA-6) was advanced and sampled to a maximum depth of approximately 5 feet bgs within a gravel-filled pit observed within a corrugated metal building on the southern portion of the 1750 South Douglass Road parcel. Soil samples were submitted to the laboratory for analysis of TPH-CCID, VOCs, OCPs, PCBs, and Title 22 Metals. ---PAGE BREAK--- 103567-ENV2/LBE9R038 ES - 5 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com One environmental soil boring (KA-7) was advanced and sampled to a maximum depth of approximately 20 feet bgs on the north side of former “Hydraulic Lift This former lift was located within a concrete tilt-up building at the 1750 South Douglass Road parcel. Soil samples were submitted to the laboratory for analysis of TPH-CCID, VOCs, OCPs, and PCBs. Five environmental soil borings (KA-10 through KA-12, KA-14, and KA-15) were advanced and sampled to a maximum depth of approximately 20 feet bgs at former UST and dispenser island locations. Borings KA-10 and KA-12 were installed in the vicinity of former diesel and gasoline USTs and Boring KA-11 was installed in the vicinity of a former dispenser island. Soil samples from these borings were submitted to the laboratory for analysis of TPH-CCID and VOCs. Borings KA-14 and KA-15 were installed in the vicinity of former waste oil USTs, and soil samples from these borings were submitted to the laboratory for analysis of TPH-CCID, VOCs, and PCBs. A summary of the assessment’s findings and conclusions is presented below: Diesel- and oil-range TPH, at respective concentrations of 15.4 milligrams per kilogram (mg/kg) and 109 mg/kg, were detected in one soil sample collected from 20 feet bgs from Boring KA-7, which was drilled on the north side of former “Hydraulic Lift The chromatograms for the diesel- and oil-range results were reported by the analytical laboratory to not match that of the diesel and motor oil standards, which suggests the presence of hydraulic oil instead of diesel fuel and motor oil. Because the 20-foot bgs sample was the deepest sample collected from this boring, it is not known whether TPH concentrations increase below a depth of 20 feet. The organochlorine pesticide (DDT) was detected at a concentration of 0.002 mg/kg in one soil sample, collected from approximately 10 feet bgs in Boring B-2, which was drilled in the central portion of the Site parcel at 1750 South Douglass Road. Deeper soil samples (collected at approximate depths of 20, 30, 40, and 50 feet bgs) that were analyzed from this boring did not contain detected DDT concentrations at or above the laboratory practical quantitation limits (PQLs). To assist in assessing the ---PAGE BREAK--- 103567-ENV2/LBE9R038 ES - 6 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com significance of the detected DDT concentration, Kleinfelder compared the result to the DDT US EPA Regional Screening Level (RSL) for Industrial Soil, and to the DDT California Human Health Screening Level for Commercial/Industrial Land Use Soil. The RSLs and are human health risk-based tools for evaluating and cleaning up contaminated sites. They are considered to be protective for humans (including sensitive groups) over a lifetime. Residential values are lower and therefore more conservative than the corresponding values for Commercial/Industrial Use, but because residential Site use is not presently planned, the commercial/industrial values were judged to be appropriate for use in the comparison with Site data. Generally, if contaminant concentrations fall below RSLs and no further action or study is warranted, so long as the exposure assumptions match those taken into account by the screening value calculations. The DDT Industrial Soil RSL is 7.0 mg/kg and the DDT Soil for Commercial/Industrial Land Use is 6.4 mg/kg. Because the detected DDT concentration is far below its Industrial Soil RSL and Commercial/ Industrial Land Use Soil in Kleinfelder’s opinion no further study with regard to concern for human health is warranted by this finding. Additionally, the detected DDT concentration was compared to the CCR Title 22 Total Threshold Limit Concentration (TTLC) value for DDT of 1.0 mg/kg, and also 10 times the CCR Title 22 Soluble Threshold Limit Concentration (STLC) value for DDT of 0.1 milligram per liter (mg/L). If a constituent’s concentration in waste soil exceeds the constituent’s TTLC value (assuming there is one), then the waste is California-hazardous. If a constituent’s concentration in a soil waste is 10 times its STLC value or higher, then analysis for the soluble constituent is required to determine if the waste is California-hazardous. Certain constituents also have Federal and/or CCR Title 22 Toxicity Characteristic Leaching Procedure (TCLP) values, which are used to assess whether a waste is Resource Conservation and Recovery Act (RCRA)-hazardous, but DDT does not have a TCLP value. Since the detected DDT concentration is less than 10 times the DDT STLC value and also below the DDT TTLC value, on the basis of this result the tested soil would be considered a non-hazardous waste. The VOC toluene was detected in 16 soil samples collected from various depths (to a maximum of approximately 50 feet bgs) in Borings B-1, B-2, and B-4, at a ---PAGE BREAK--- 103567-ENV2/LBE9R038 ES - 7 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com maximum concentration of 0.035 mg/kg. The VOC 2-butanone (also known as methyl ethyl ketone [MEK]) was detected in one soil sample, collected from approximately 20 feet bgs from Boring B-2, at a concentration of 0.039 mg/kg. Based on our evaluation of the data and our knowledge of the Site, the source (or sources) of these VOC constituents is not readily apparent. The maximum detected concentrations of toluene and MEK are below their respective US EPA Industrial Soil RSLs of 46,000 mg/kg and 195,000 mg/kg. VOCs do not have established Soil and the presence of these VOCs may pose indoor air intrusion concerns should a building be constructed in the vicinity of the sampled locations. MEK has both a Federal and CCR Title 22 TCLP value of 200 mg/L. If a constituent concentration in a soil sample is 20 times its TCLP value or higher, analysis for the soluble constituent is warranted to assess whether the material is a hazardous waste. The detected 0.039 mg/kg concentration of MEK is far below 20 times the MEK TCLP value, so on the basis of these results, the tested soil would be considered a non-hazardous waste. TPH, VOCs, and OCPs were not detected at or above their respective PQLs in the remaining analyzed soil samples. PCBs were not detected at or above their respective PQLs in the analyzed soil samples. The detected concentrations of metals in the soil samples for which they were analyzed are below their respective and RSLs and also below hazardous waste thresholds including CCR Title 22 TTLC values, 10 times the CCR Title 22 STLC values, and 20 times the Federal and CCR Title 22 TCLP values. On the basis of these results, in Kleinfelder’s opinion no further study with regard to concern for human health is warranted by the detected metals, and the tested soil would be considered a non-hazardous waste. In summary, petroleum hydrocarbons in the diesel and oil ranges were detected in a soil sample collected at approximately 20 feet bgs from Boring KA-7, in the area of the former location of “Hydraulic Lift This is the area of a historic petroleum hydrocarbon release known to have impacted soil, where remedial excavation was performed under oversight of the Orange County Health Care Agency (OCHCA), which ---PAGE BREAK--- 103567-ENV2/LBE9R038 ES - 8 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com issued a November 21, 2008 “no further action” letter (OCHCA Case No. 08IC027) confirming completion of the remedial action. Because the 20-foot bgs sample was the deepest sample collected by Kleinfelder from this boring, it is not known whether higher TPH concentrations may be present below a depth of 20 feet bgs. For this reason, Kleinfelder recommends additional assessment of the vertical extent of impact to soil in this area, especially if Site redevelopment will involve excavation at this location. In addition, the VOC toluene was detected in soil samples from various depths (to a maximum of 50 feet bgs) from Borings B-1, B-2, and B-4, and the VOC MEK was detected in one soil sample collected from approximately 20 feet bgs from Boring B-2. Based on our evaluation of the data and our knowledge of the Site, the source (or sources) of these VOCs is not readily apparent. Before a building is constructed in the vicinity of these sampled locations, we recommend assessment of the potential for indoor air intrusion, by performing a limited soil vapor survey. Kleinfelder’s scope of services did not include soil sampling within the railroad right of way on the Site, or sampling of groundwater beneath the Site. To minimize risk, we therefore recommend performing soil sampling to assess for petroleum hydrocarbons, agricultural chemicals, heavy metals, and creosote in the vicinity of the railroad right of way, and performing groundwater sampling to assess for potential impact to groundwater beneath the Site resulting from upgradient off-Site facilities where releases are known to, or may, have impacted shallow groundwater. ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 1 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com 1 INTRODUCTION This report presents the results of a Limited Preliminary Phase II ESA performed by Kleinfelder of the proposed ARTIC - Phase 1 project site, generally located at the southeast corner of Katella Avenue and South Douglass Road in the City of Anaheim, Orange County, California. The assessment was performed to assess the following RECs and potential RECs that were identified in Kleinfelder’s Phase I ESA of the Site, dated July 17, 2009: Blue-green colored staining was observed on asphalt pavement and concrete, near a dipping vat and within a drainage swale, at the Sullivan & Mann Lumber Company at 1790 South Douglass Road. A gravel-filled pit was observed within a corrugated metal building on the southern portion of the Site parcel with an address of 1750 South Douglass Road. The former use of this pit is unknown to Kleinfelder and previous sampling in this area was not identified by the Phase I ESA. The presence of undocumented fill material was reported in a former quarry on the Site parcel with an address of 1750 South Douglass Road. In addition to the RECs and potential RECs discussed above, Kleinfelder also assessed the following potential areas of concern which we believe warranted further investigation and/or confirmation sampling: An inactive laboratory and a former hazardous materials storage shed are located at 1750 South Douglass Road. In addition, a paint booth was formerly located inside the present-day warehouse building at 1790 South Douglass Road. Paint staining was observed in close proximity to a floor drain at 1750 South Douglass Road, adjacent to a former hazardous materials storage building. This Site parcel at 1750 South Douglass Road also contained a former fueling facility including two 10,000 gallon gasoline USTs, one 10,000-gallon diesel UST, ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 2 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com two 5,000-gallon diesel USTs, and associated fuel dispensers. These USTs, along with two 280-gallon and 300-gallon capacity waste oil USTs that were located farther to the east on the Site, were removed in March 1998. The gasoline and diesel USTs were replaced with a 20,000-gallon gasoline UST and a 20,000-gallon diesel UST, which were removed, along with the associated dispensers, in July 2008. OCHCA issued a Remedial Action Completion Certification dated June 19, 1998 for the investigation and remedial action for the USTs removed in March 1998. A March 4, 2009 letter with subject “No Further Action for Diesel Fuel and Gasoline Contaminated Soil” was issued by the Anaheim Public Utilities Department (APUD) to the Orange County Department of Public Works (OCPW) for removal of the USTs in July 2008, in reference to Santa Ana Regional Water Quality Control Board Case No. 083003990T. Based on Kleinfelder’s review of available Site assessment information, the maximum detected concentrations of BTEX were in samples from a boring (B-3) advanced by Tait to the north of the two former 10,000-gallon gasoline USTs. Soil hydrocarbon impact was also evident in samples from Tait’s Boring B-5, which was located by a former dispenser island beneath a presently-existing canopy; and in Boring B-6, which was located between the two former 5,000-gallon diesel USTs. Borings B-5 and B-6 are at the locations where Tait reported the highest concentrations of TPH from its assessment. Additionally, Block reported detected concentrations of TRPH and PCE in samples of soil stockpiled from removal of the two former waste oil USTs. Three hydraulic lifts and associated equipment and piping were removed from the Site parcel at 1750 South Douglass Road in September and October 2008 under the oversight of OCHCA, which subsequently issued a November 21, 2008 case closure letter (OCHCA Case No. 08IC027) confirming completion of remedial action. A soil sample collected at a depth of approximately 15 feet bgs from a remedial excavation on the north side of former “Hydraulic Lift apparently contained the highest detected TPH concentration for soil not subsequently removed from this area. Four wastewater clarifiers and associated sewer piping systems were removed from the Site parcel at 1750 South Douglass Road in October 2008. OCHCA’s ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 3 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com aforementioned November 21, 2008 Closure Letter (OCHCA Case No. 08IC027) also confirmed completion of remedial action associated with removal of these clarifiers. The excavation areas were filled with gravel but not sealed at the surface. This Limited Preliminary Phase II ESA included performing soil sampling, laboratory analyses, and data evaluation, along with formulation of conclusions and recommendations. Kleinfelder’s scope of services did not include sampling soil within the railroad right of way on the Site or sampling of groundwater beneath the Site. For this reason, although identified as potential RECs in the Phase I ESA report, the following were not addressed as part of this Limited Preliminary Phase II ESA: Former “pouring” of oil along the railroad tracks at/near the Anaheim Stadium Metrolink/Amtrak Station and the potential presence of agricultural chemicals (due to former agricultural land use on surrounding areas from at least 1938 through at least 1952), and heavy metals and creosote (from treated railroad ties associated with the railroad tracks). Potential impacts to Site groundwater resulting from upgradient off-Site facilities where releases are known to, or may, have impacted shallow groundwater. 1.1 SITE DESCRIPTION The Site is an irregularly-shaped property consisting of nine parcels or portions thereof, which are occupied by commercial buildings, a former operations-and-maintenance facility, a lumber facility, a portion of the Los Angeles to San Diego (LOSSAN) Railroad Corridor, and the Anaheim Stadium Metrolink/Amtrak Station, or are vacant land. The vacant parcels are generally small areas along the LOSSAN Railroad Corridor that do not have associated addresses. The approximate location of the Site, with respect to surrounding topographic features, is shown on Plate 1. 1.2 SITE HISTORY Available historic information reviewed during Kleinfelder’s Phase I ESA of the Site indicates that the eastern portion of the Site (east of the approximate present-day ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 4 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com location of State Route 57) appeared to be part of the Santa Ana River from at latest 1938 through 1952. Also during this period, the area of the Site which is presently occupied by the Anaheim Stadium Metrolink/Amtrak Station appeared to have been used for agricultural purposes (orchards). By at latest 1976 the Site was partially developed east of South Douglass Road and the Metrolink/Amtrak Station was in operation. Construction of the remaining developed portions of the Site took place subsequent to 1976. 1.3 PROJECT UNDERSTANDING We understand that the Site is proposed to be re-developed as a major transit center that will provide Metrolink, Amtrak, and fixed-route bus service, and function as a regional gateway for the future California High Speed Train. 1.4 ASSESSMENT OBJECTIVES The objective of this Limited Preliminary Phase II ESA was to assess RECs and potential RECs identified in Kleinfelder’s Phase I ESA (Kleinfelder, 2009). The scope of services included the following: Performing a geophysical survey to locate identifiable subgrade utility lines in the immediate vicinity of proposed boreholes. Performing soil sampling activities, including the use of hollow-stem auger drilling and direct-push Geoprobe® technologies. Performing laboratory analysis of soil samples. Evaluating the results and documenting the assessment’s findings and conclusions in this report. ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 5 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com 2 FIELD ACTIVITIES Kleinfelder provided personnel to perform a geophysical survey and drilling/soil sampling with the assistance of our contractors. Kleinfelder also documented observations in the field, submitted samples for laboratory analyses, evaluated the field and analytical data, and prepared this report of findings. The following provides a description of field activities performed as part of this Limited Preliminary Phase II ESA. 2.1 HEALTH AND SAFETY PLAN AND RELATED ACTIVITIES Prior to the initiation of field activities Kleinfelder prepared a Site-specific health and safety plan (HSP). The HSP included information concerning anticipated chemical and physical hazards that would potentially be encountered, and environmental monitoring equipment to be used during field activities. Ambient air monitoring and screening of soil samples for total VOCs with a photo-ionization detector (PID) were performed during sampling activities. Site safety was discussed with the drilling subcontractor on-Site prior to sampling. A cellular phone was available at the Site to facilitate potential emergency response. Additionally, directions to the nearest hospital were included with the HSP presented to field personnel. 2.2 UTILITY CLEARANCE Underground Service Alert (DigAlert) provided a partial location service for major utility lines free of charge. California law requires at least 48 hours (2 business days) advance notification of DigAlert prior to performing intrusive activities, and Kleinfelder provided the required notification in accordance with State requirements to arrange for utility marking within accessible areas. Because DigAlert may not mark underground utilities on private property, a geophysical services subcontractor was contracted to locate and mark detectable utility lines at proposed sampling locations. Geophysical instruments were used to survey the sampling locations for underground obstructions prior to initiation of intrusive field ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 6 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com activities. Visual inspections of the sampling areas were also performed to assess potential subsurface obstructions. 2.3 SOIL SAMPLING The following sections discuss the soil sampling activities performed during this assessment. 2.3.1 Sampling Program The proposed sampling approach included the collection of soil samples from identified areas of potential environmental concern. The soil sampling was performed using a combination of drilling methods, including a conventional hollow-stem auger drill rig used between September 22 and 25, 2009, and a direct-push Geoprobe® drill rig used on October 15 and 16, 2009. Prior to drilling, direct-push sampling locations on asphalt concrete pavement and concrete were cored using a core drill. Each boring location was subsequently cleared using a hand auger to a depth of approximately 5 feet bgs, during which time a near-surface soil sample sample of first-encountered soil) from each boring was collected using the “grab” sampling method. Kleinfelder’s subcontractor California Pacific Drilling (Cal Pac) performed drilling of Borings B-1 through B-5 and Boring W-1 with a truck-mounted drill rig using hollow-stem augers. After collection of the “grab” near-surface sample, soil samples were collected from each of these borings using a California-modified split spoon sampler driven approximately 18 inches for each sample interval. These soil samples were collected beginning at a depth of approximately 5 feet bgs, then at approximately 10 feet bgs, and continuing at approximate 10-foot intervals beneath to a maximum depth of 50 feet bgs. Kleinfelder’s subcontractor HydroGeoSpectrum (HGS) performed direct-push drilling at 16 boring locations (KA-1 through KA-16) using a conventional truck-mounted ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 7 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com Geoprobe® drill rig or limited-access direct-push drill rig, as dictated by Site access conditions. Following collection of a “grab” near-surface sample at each location, soil samples were collected at varying depths, beginning at a depth of approximately 3 feet bgs at selected locations and continuing to a maximum depth of approximately 25 feet bgs. For each specified sampling location and depth, the Geoprobe® soil sampling system was attached to deployment rods, advanced to the desired sampling depth, and subsequently driven approximately 2 feet (unless refusal was encountered) to acquire the soil sample. 2.3.2 Soil Sample Collection Kleinfelder field personnel performed the soil sampling under the technical guidance of a State of California Professional Geologist (PG). The near-surface soil samples were collected using a decontaminated hand auger and placed into 8-ounce glass jars and pre-preserved volatile organic analysis (VOA) vials as further discussed below. Relatively-undisturbed soil samples were collected from the hollow-stem auger borings using a split-spoon sampler lined with 2.5-inch diameter by 6-inch long stainless steel sleeves, and from the direct-push borings using a Geoprobe® soil sampler lined with acetate sleeves. For each specified sampling depth in each boring, a portion of the retrieved soil core sample was cut off and covered with Teflon® sheeting followed by tight-fitting plastic caps. Soil samples were screened in the field using a PID calibrated to a 50-part per million by volume (ppmv) hexane standard. The PID had a detection limit of 0.1 ppmv. A portion of the soil from each sample interval was placed in a clean, resealable plastic bag that was subsequently sealed. The bag remained sealed at ambient air temperature for approximately 10 minutes to allow potential VOC vapors to volatize into the bag’s headspace. Then the probe tip of the PID was placed into the bag by unsealing a small length of the seal, and the VOC vapor reading was recorded on the log of boring (see logs provided in Appendix ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 8 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com For soil samples intended for VOC analysis, a portion of the soil sample was placed in pre-preserved, laboratory-prepared VOA vials in accordance with US EPA Method 5035. Each soil sample was labeled with a unique sample identification number, the project number, and date, and placed in an ice-chilled cooler for delivery under chain-of-custody (COC) protocol for analysis to Enviro-Chem, Inc. in Pomona, California. Except for Boring W-1, after completion of soil sampling each boring was back-filled with bentonite slurry or hydrated bentonite chips or granules, and then the surface was patched with asphalt or concrete if appropriate to match the surrounding area. Boring W-1 was subsequently converted to a geotechnical monitoring well. 2.3.3 Borehole Logging Kleinfelder field personnel, under the technical guidance of a State of California PG, examined the sampled soil and classified it in general accordance with the Unified Soils Classification System (USCS), using visual-manual procedures as described in ASTM International (formerly known as American Society for Testing and Materials) Designation D 2488-93. Additional geologic observations were noted as appropriate. 2.3.4 Equipment Decontamination Drilling equipment used in Kleinfelder’s assessment was decontaminated prior to use by high-pressure hot water washing. Soil sampling equipment was cleaned prior to collecting each sample by washing in a non-phosphate detergent Liquinox®) and tap water wash, using a brush to dislodge soil, dirt, or other encrusted materials, and then double rinsing in distilled water. ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 9 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com 2.3.5 Investigation-Derived Waste For soil borings drilled using the hollow-stem auger drill rig, soil cuttings were collected and contained in labeled Department of Transportation (DOT) 17H, 55-gallon drums, and temporarily stored on the Site pending profiling and disposal. Rinse water generated during cleaning of equipment was also collected and contained in labeled DOT 17H, 55-gallon drums pending disposal. For soil borings drilled using direct-push equipment, the soil sampling generated minimal to no soil cuttings. ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 10 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com 3 ANALYTICAL PROGRAM The following is a summary of the analyses performed on soil samples collected from the Site. Based on field observations and Site use, soil samples from the following borings were analyzed for the indicated constituents: Soil samples collected from Borings B-1 through B-5 and Boring W-1 were analyzed for TPH-CCID using US EPA Method 8015B, VOCs including fuel oxygenates using US EPA Methods 5035/8260B, OCPs using US EPA Method 8081A, PCBs using US EPA Method 8082, and Title 22 Metals using US EPA Methods 6010B/7471A. Soil samples collected from Borings KA-1 and KA-2 were analyzed for TPH-CCID using US EPA Method 8015B, VOCs using US EPA Methods 5035/8260B, and Title 22 Metals using US EPA Methods 6010B/7471A. Soil samples collected from Borings KA-3, KA-4, KA-6, and KA-9 were analyzed for TPH-CCID using US EPA Method 8015B, VOCs using US EPA Methods 5035/8260B, OCPs using US EPA Method 8081A, PCBs using US EPA Method 8082, and Title 22 Metals using US EPA Methods 6010B/7471A. Soil samples collected from Borings KA-5, KA-7, KA-8, KA-13, and KA-16 were analyzed for TPH-CCID using US EPA Method 8015B, VOCs using US EPA Methods 5035/8260B, OCPs using US EPA Method 8081A, and PCBs using US EPA Method 8082. Soil samples collected from Borings KA-10 through KA-12 were analyzed for TPH-CCID using US EPA Method 8015B and VOCs using US EPA Methods 5035/8260B. ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 11 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com Soil samples collected from Borings KA-14 and KA-15 were analyzed for TPH-CCID using US EPA Method 8015B, VOCs using US EPA Methods 5035/8260B, and PCBs using US EPA Method 8082. The soil analytical laboratory reports and chain-of-custody records are provided in Appendix B. ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 12 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com 4 RESULTS 4.1 FIELD RESULTS The soils encountered in the borings consisted of interbedded layers of sand, silty sand, clayey sand, sandy silt, gravel, clay, and sandy clay. Based on Kleinfelder’s review of the logs, sands and silty sands appear to predominate at relatively shallow depths (to approximately 20 to 60 feet bgs depending on the location), whereas silts and clays tend to predominate at deeper depths (to approximately 80 to 85 feet bgs), although the deeper soils in Borings B-4, B-5, and W-1 include interbedded sand, silty sand, and gravel. Groundwater was encountered in only four of Kleinfelder’s borings, at an approximate depth of 83 feet bgs in Boring B-2, 58 feet bgs in Boring B-3, 87 feet bgs in Boring B-4, and 25 feet bgs and 56 feet bgs in Boring W-1. Based on deeper soil samples that were not wet in Borings B-3 and W-1, the groundwater encountered in these borings appears likely to have been perched. Groundwater was not encountered in the remaining borings, although the geotechnical soil sample collected from 51 feet bgs in Boring B-1 exhibited free water, suggesting a possibility of perched groundwater at this location also. A more-detailed description of the interpreted soil profile at each of the boring locations, based on the logged soil samples, is presented in Appendix A. The indicated groupings represent the predominant materials encountered, although relatively thin, discontinuous layers of different material may occur within the major divisions. Petroleum hydrocarbon odors were noted in the two soil samples collected from Boring KA-12 at approximately 15 feet bgs and 19 feet bgs. There were no noticeable chemical/hydrocarbon odors or staining in the soil samples collected from the remaining borings. VOC vapors were detected by the PID in the screened soil samples from the following borings: Boring B-1 – Five samples, at concentrations ranging from 0.5 ppmv to 2.0 ppmv. Boring B-2 – 12 samples, at concentrations ranging from 1.1 ppmv to 4.6 ppmv. Boring B-3 – Six samples, at concentrations ranging from 0.5 ppmv to 2.3 ppmv. Boring B-4 – Six samples, at concentrations ranging from 0.4 ppmv to 3.6 ppmv. ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 13 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com Boring B-5 – Eight samples, at concentrations ranging from 0.9 ppmv to 3.1 ppmv. Boring KA-15 – Two samples, at concentrations ranging from 0.2 ppmv to 0.4 ppmv. Boring KA-16 – Two samples, at concentrations ranging from 0.2 ppmv to 0.8 ppmv. 4.2 SOIL ANALYTICAL RESULTS Analytical results for organic constituents (TPH-CCID, VOCs, OCPs, and PCBs) are summarized in Table 1. Analytical results for Title 22 Metals are summarized in Table 2. Approximate boring locations are shown on Plate 2. A summary of soil analytical results for the areas assessed follows: TPH in the diesel and oil ranges were detected in the 20-foot bgs soil sample collected from Boring KA-7, at respective concentrations of 15.4 mg/kg and 109 mg/kg. Boring KA-7 was drilled on the north side of former “Hydraulic Lift The chromatograms for the diesel- and oil-range results were reported by the analytical laboratory to not match that of the diesel or motor oil standards. No TPH in the gasoline, diesel, and oil ranges was detected at or above the PQLs in the remaining analyzed soil samples. The VOC toluene was detected in 16 soil samples collected from various depths (maximum of approximately 50 feet bgs) in three borings (B-1, B-2, and B-4). Toluene was detected at a maximum concentration of 0.035 mg/kg in the 20-foot bgs soil sample collected from Boring B-2. Toluene was not detected in samples from the remaining borings. The VOC MEK was detected at a concentration of 0.039 mg/kg in the 20-foot bgs soil sample collected from Boring B-2, but was not detected at or above the PQL in either the other analyzed samples from this boring or in samples from other borings. ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 14 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com No other VOCs were detected at or above the laboratory PQLs in the analyzed soil samples. The organochlorine pesticide DDT was detected in the 10-foot bgs soil sample collected from Boring B-2 at a concentration of 0.002 mg/kg. No other OCPs were detected at or above the laboratory PQLs in this sample. No OCPs were detected at or above the laboratory PQLs in the remaining analyzed soil samples. No PCBs were detected at concentrations at or above the laboratory PQLs in the analyzed soil samples. Nine of the 17 CCR Title 22 Metals were detected at or above their respective PQLs in some or all of the analyzed soil samples. Cadmium was detected in three samples, at a maximum concentration of 0.669 mg/kg in the 1-foot bgs sample from Boring KA-1. Cobalt was detected in 15 samples, at a maximum concentration of 4.69 mg/kg in the 5-foot bgs sample from Boring KA-2. Nickel was detected in 42 samples, at a maximum concentration of 18.8 mg/kg in the 20-foot bgs sample from Boring B-5. Lead was detected in 52 samples, at a maximum concentration of 33.8 mg/kg in the 5-foot bgs sample from Boring KA-2. Copper was detected in 55 samples, at a maximum concentration of 57.1 mg/kg in the 40-foot bgs sample from Boring B-2. Vanadium was also detected in 55 samples, at a maximum concentration of 55.4 mg/kg in the 20-foot bgs sample from Boring B-5. Barium was detected in 58 samples, at a maximum concentration of 157 mg/kg in the 20-foot bgs sample from Boring B-5. Chromium and zinc were detected in all 59 soil samples, at respective maximum concentrations of 27.6 mg/kg and 97.8 mg/kg, in the 20-foot bgs sample from Boring B-5. The remaining eight CCR Title 22 Metals were not detected at or above their respective PQLs in the 59 soil samples analyzed for metals. The eight metals that were not detected were antimony, arsenic, beryllium, mercury, molybdenum, silver, selenium, and thallium. ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 15 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com 5 EVALUATION, CONCLUSIONS, AND RECOMMENDATIONS Detected concentrations of analytes in soil were compared to the April 2009 RSLs for Industrial Soil tabulated by US EPA (US EPA, 2009) and to Soil for Commercial/Industrial Land Use published by the California Environmental Protection Agency (Cal/EPA) in January 2005 (Cal/EPA, 2005), providing that the specific analyte had an RSL and/or The RSLs and are human health risk-based tools for evaluating and cleaning up contaminated sites. They are considered to be protective for humans (including sensitive groups) over a lifetime. Residential values are lower and therefore more conservative than the corresponding values for Commercial/Industrial Use, but because residential Site use is not presently planned, the commercial/industrial values were judged to be appropriate for use in the comparison with Site data. Generally, if contaminant concentrations fall below RSLs and no further action or study is warranted, so long as the exposure assumptions match those taken into account by the screening value calculations. Analyte concentrations in soil were also compared to CCR Title 22 hazardous waste thresholds the TTLC values and 10 times the STLC values) and to the Federal and CCR Title 22 TCLP values, again providing that there were such values for the specific analyte. If a constituent’s concentration in waste soil exceeds the constituent’s TTLC value (assuming there is one), then the waste is California-hazardous. If a constituent’s concentration in a soil waste is 10 times its STLC value or higher, then analysis for the soluble constituent is required to determine if the waste is California-hazardous. Certain constituents also have Federal and/or CCR Title 22 TCLP values, which are used to further assess whether a waste is RCRA-hazardous. If a constituent concentration in a soil sample is 20 times its TCLP value or higher, analysis for the soluble constituent is warranted to determine if the material may be a hazardous waste. Based on the results and findings of this assessment, Kleinfelder concludes the following: Diesel-range and oil-range TPH, at respective concentrations of 15.4 mg/kg and 109 mg/kg, were detected in one soil sample, collected at 20 feet bgs from ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 16 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com Boring KA-7, which was drilled on the north side of the location of former “Hydraulic Lift The fact that the chromatograms for the diesel- and oil-range results were reported by the analytical laboratory to not match that of the diesel or motor oil standard suggests the presence of hydraulic oil in this sample instead of diesel fuel and motor oil. Although the total TPH concentration of 124.4 mg/kg does not necessarily warrant action, the 20-foot bgs sample was the deepest sample collected from this boring, so it is not known whether TPH concentrations increase below a depth of 20 feet. For this reason, additional assessment of the vertical extent of impact to soil in this area is recommended, especially if Site redevelopment will involve excavation in this area. DDT was detected at a concentration of 0.002 mg/kg in one soil sample, collected from approximately 10 feet bgs in Boring B-2, which was drilled in the central portion of the Site’s 1750 South Douglass Road parcel. The detected concentration is far below the US EPA Industrial Soil RSL of 7.0 mg/kg and the Soil Commercial/Industrial Land Use of 6.4 mg/kg. Based on this, in Kleinfelder’s opinion no further study with regard to concern for human health is warranted. Additionally, the detected DDT concentration is far below the CCR Title 22 TTLC value for DDT of 1.0 mg/kg, and also far below 10 times the CCR Title 22 STLC value for DDT of 0.1 mg/L. Since DDT does not have a TCLP value and the detected DDT concentration is less than 10 times the DDT STLC value and also below the DDT TTLC value, on the basis of these results the tested soil would be considered non-hazardous waste. DDT was not detected at or above the laboratory PQLs in the deeper soil samples (20, 30, 40, and 50 feet bgs) analyzed from this boring. No additional assessment is recommended for DDT. The VOC toluene was detected at a maximum concentration of 0.035 mg/kg in 16 soil samples collected from various depths (to a maximum of approximately 50 feet bgs) in Borings B-1, B-2, and B-4. In addition, the VOC MEK was detected in one soil sample, collected from approximately 20 feet bgs from Boring B-2, at a concentration of 0.039 mg/kg. Based on our evaluation of the data and our knowledge of the Site, the source of these VOC constituents is not readily apparent. The detected maximum concentrations of toluene and MEK ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 17 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com are below their respective US EPA Industrial RSLs of 46,000 mg/kg and 195,000 mg/kg. Toluene and MEK do not have soil and the presence of these VOCs may pose indoor air intrusion concerns should a building be constructed in the vicinity of the sampled locations. Before a building is constructed in the area of these locations, we recommend assessment of the potential for indoor air intrusion by performing a limited soil vapor study. MEK has both a Federal and CCR Title 22 TCLP value of 200 mg/L. The detected 0.039 mg/kg concentration of MEK is far below 20 times the TCLP value, so on the basis of these results the tested soil would not be considered a hazardous waste. The detected concentrations of metals in the soil samples analyzed for these constituents are below hazardous waste thresholds including TTLC values, 10 times the STLC values, and 20 times the TCLP values. The detected metal concentrations in the soil samples are also below their respective RSLs and Kleinfelder therefore recommends no further assessment concerning the detected metals. TPH, VOCs, and OCPs were not detected at or above PQLs in the remaining soil samples collected from these and other sampled locations. No additional assessment of these other areas is recommended. PCBs were not detected at or above PQLs in the soil samples. No additional assessment for PCBs is recommended. In summary, petroleum hydrocarbons in the diesel and oil ranges were detected in a soil sample collected at approximately 20 feet bgs from Boring KA-7, in the area of the former location of “Hydraulic Lift This is the area of a historic petroleum hydrocarbon release known to have impacted soil, where remedial excavation was performed under oversight of OCHCA, which issued a November 21, 2008 “no further action” letter (OCHCA Case No. 08IC027) confirming completion of the remedial action. Because the 20-foot bgs sample was the deepest sample collected by Kleinfelder from this boring, it is not known whether higher TPH concentrations may be present below a depth of 20 feet bgs. We therefore recommend further assessment of the extent of impact to soil in this area, especially if Site redevelopment will involve excavation here. ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 18 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com In addition, VOC constituents were encountered at various depths, up to 50 feet bgs, in soil samples from Borings B-1, B-2, and B-4. Based on our evaluation of the data and our knowledge of the Site, the source of these VOCs is not readily apparent. Before a building is constructed in the vicinity of these sampled locations, we recommend assessment of the potential for indoor air intrusion by performing a limited soil vapor survey. Based on laboratory analytical results for the other analyzed constituents and areas of potential concern, no apparent significant impact has resulted from former Site operations in the other areas investigated. Kleinfelder’s scope of services did not include soil sampling within the railroad right of way on the Site or sampling of groundwater beneath the Site. To minimize risk, we therefore recommend performing soil sampling to assess for petroleum hydrocarbons, agricultural chemicals, heavy metals, and creosote in the vicinity of the railroad right of way, and performing groundwater sampling to assess for potential impact to groundwater beneath the Site resulting from upgradient off-Site facilities where releases are known to, or may, have impacted shallow groundwater. If unanticipated suspect soil contamination is encountered during future Site redevelopment activities, Kleinfelder recommends stopping construction activity in the area, implementing appropriate health and safety procedures, and notifying Kleinfelder so that we may perform further assessment. ---PAGE BREAK--- 103567-ENV2/LBE9R038 Page 19 of 21 December 23, 2009 Copyright 2009 Kleinfelder 620 W. 16th Street, Unit F Long Beach, CA 90813 pI [PHONE REDACTED] fI [PHONE REDACTED] kleinfelder.com 6 LIMITATIONS This work was performed in a manner consistent with that level of care and skill ordinarily exercised by other members of Kleinfelder’s profession practicing in the same locality, under similar conditions and at the date the services are provided.
