Office of Environmental Services 1715 Chester Ave. Bakersfield, CA., 93301 Subject: Site Characterization Report Schwebel Petroleum Company Bulk Plant 900 Sacramento St. Bakersfield, CA. I I I I Mr. Underwood: This Site Characterization Report (Report) is submitted by Soils Engineering, Inc. (SEI) following the completion of field activities and the receipt of analytical test results at the Schwebel Petroleum Company Bulk Plant located at 900 Sacramento Street in Bakersfield, CA. (site). SEI advanced 5 soil borings to a depths ranging from 35 feet to 81 feet in the area of the former underground storage tank (UST's) areas to collect soil samples for chemical analysis. The environmental investigation was conducted in accordance with a Site Characterization Workplan (Workplan) dated July 22, 1999 prepared by SEI and approved by the Bakersfield Fire Department Office of Environmental Services (BFDES) in a letter dated August 6, 1999. I I I I I BACKGROUND On August 4, 1998 BC Enterprises (BCE) removed one (1) 550-gallon waste oil UST and on May 7, 1999 BCE removed six (6) 6,000 gallon UST's. Elevated petroleum hydrocarbons were detected in soil samples collected beneath the waste oil UST and beneath the product pipeline extending from the 6 UST's to the northern and eastern dispensers and at the eastern end of the east-central tank (sample TK-3). The UST's evidently contained motor oils, gasoline, diesel, and mineral spirits over the period of operation. The BFDES requested additional site characterizations be conducted beneath the former waste oil UST and the former 6,000 gallon UST's to determine the lateral and vertical extent of the petroleum release. The Department of Toxic Substance Control (DTSC) is the lead agency for the closure of the former waste oil tank which was part of a Hazardous Waste Storage area. A separate Site Characterization & Closure Plan for the former waste oil tank will be prepared.

Soil boring B-2 was placed near the center of the 6 former 6,000 gallon UST's and associated product piping and drilled to a depth of 81' bgs.. Soil boring B-3 was placed on the eastern edge of the former UST's approximately 25 feet east of B-1 and advanced to a depth of 40' bgs.. Soil boring B-4 was placed 18 feet southwest of B-2 near the southern edge of the former UST's and drilled to a depth of 35' bgs.. Soil boring B-5 was located at the former solvent dispenser approximately 23 feet north of B-2 to a depth of 40' bgs.. Soil boring B-6 was placed approximately 20 feet northeast of B-5 to define the lateral extent of contamination north of B-5 and drilled to a depth of 40' bgs.. A California registered geologist supervised the drilling process. Soil samples were collected at 5 to 10 foot intervals and evaluated in the field for petroleum hydrocarbons (staining and odor), soil type and photo-ionization detector (PID) readings. A soil sample from each sampling interval was sealed, labeled and placed in an iced cooler. See Plate 2 for soil boring locations. The augers were steamcleaned between borings and the sampling equipment decontaminated between sampling intervals to prevent cross-contamination. The soil borings were backfilled with neat cement. The soil cuttings were stockpiled in a roll-off bin and covered by plastic sheeting. A composite soil sample (ROB-l) was collected from the stockpiled cuttings and analyzed for profiling purposes prior to disposal/recycling activities. Analytical Testing Selected soil samples from the soil borings were analyzed for Total Recoverable Petroleum Hydrocarbons (TRPH), Total Petroleum Hydrocarbons as gasoline (TPHg), Total Petroleum Hydrocarbons as diesel (TPHd), and for benzene, toluene, ethylbenzene, and total xylenes (BTEX), and MTBE at a State certified analytical laboratory. In addition soil sample B3-30' was analyzed for fuel f'mgerprinting and for volatile organics by EPA Method 8260. The composite soil sample ROB-1 from the stockpiled soil was analyzed for volatile organics by EPA Method 8260, TPHg, TPHd, TRPH, BTEX and MTBE, pH and CAM 17 Metals. FINDINGS Soil Characteristics Soil encountered in the 5 soil borings conducted at the site in general consisted of silty sand (SM) and well graded sand (SW) to a depth of approximately 25' bgs. underlain by Clayey Silt (ML) to a depth of approximately 35 ' bgs.. Clayey Sand (SC) and Sand (SW) with some gravel was I I I I Site Characterization Report 900 Sacramento St.., Bakersfield, CA. Schwebel Petroleum Co. SOILS ENGINEERING, INC. File Number 99-9015 October 28, 1999 Page 3 I I I I I I I I ! I I I I I i encountered from 35' to 43 feet bgs.. Sandy Silt (ML) and Silty Sand (SM) with some intervals of gravel (mainly 62' to 63' and 71' to 73') was observed from 43' to 81' in boring B-2. Petroleum stained soil was encountered in boring B-2 from 15' to 30' bgs., in B-3 from 12' to 25' bgs., and in B-5 from 15' to 30' bgs.. No petroleum staining was present in soil from borings B-4 and B-6. Petroleum odor was evident in soil boring B-2 from 10' to 75' bgs., in B-3 from 12' to 40' bgs., in B-5 from 15' to 35' bgs.. Below a depth of 30' bgs. the petroleum odor (if present) was predominately solvent-like (mineral spirits). The highest PID readings (over 1000 ppm) were recorded in boring B-2 from 45' to 70' bgs.. No petroleum odor was encountered in soil borings B-4 and B-6. See attached Boring Logs in Appendix B for more detail. Analytical Results of Soil Samples The analytical results of the selected soil samples analyzed from the soil borings are presented on Table 1. The analytical results indicate significant petroleum hydrocarbons are present from 30' to 60' at soil boring B-2, from 30' to greater than 40' at boring B-3 and from 20' to 35' at boring B-5. Elevated benzene concentrations were reported in soil samples B2-45' (4.35 ppm), and B2- 50' (12.8 ppm). No significant MTBE concentrations were reported in any of the soil samples analyzed by EPA Method 8260. The main contaminant below a depth of 30' bgs. appears to be mineral spirits, which is reported as TPHd on the analytical reports. Metal concentrations were in the normal range for the composite soil sample ROB-1 from the stockpiled soil cuttings. See attached analytical reports in Appendix A. CONCLUSIONS Based on field observations and soil sample analytical results SEI concludes the following: 1) Petroleum hydrocarbons are present in soil from 30' to 60 feet bgs. at soil boring B-2 in the central area of the former UST's, from 30' to at least 40' bgs. at B-3, and from 20' to approximately 35' bgs. at B-5. See Plate 3A and 3B for hydrocarbon plume cross-sections. The lateral extent of the petroleum hydrocarbon plume is approximately 40' in diameter east- west and 30' north-south. 2) Benzene concentrations in soil samples were highest at a depth of 50' at boring B-2 at 12.8 ppm. 3) The majority of the petroleum hydrocarbon plume is apparently mineral spirits, which is reported as TPHd in the analytical reports. The highest TPHd result is 23,600 ppm at 50' in boring B-2. 4) No MTBE concentrations were reported in the contaminated soil sample (B3-30') analyzed by EPA Method 8260. MTBE concentrations reported by EPA Method 8020 are not as reliable as results utilizing EPA Method 8260. I I I I Site Characterization Report 900 Sacramento St.., Bakersfield, CA. Schwebel Petroleum Co. SOILS ENGINEERING, INC. File Number 99-9015 October 28, 1999 Page 4 I I I I I I I I I I I I I I i 5) Hydrocarbon stained soil is present between approximately 15' to 30' bgs. in borings B-2, B- 3, and B-5. 6) No significant petroleum hydrocarbons are present at borings B-4 and B-6 to a depth of 35' and 40' bgs., respectively. 7) Depth to groundwater in this area as reported by the Kern County Water Agency is approximately 220' bgs. or approximately 160' below the base of the TPHd plume at B-2. 8) The nearest public drinking water well (currently inactive) is over 500' north (upgradient) of the site. REMEDIAL ALTERNATIVES The following remedial alternatives are presented for the site. Natural Attenuation The petroleum hydrocarbon plume extends to a depth of approximately 60' bgs. in the area of boring B-2. With the depth of groundwater reported at 220' bgs. there is approximately 160' of soil buffer zone between the base of the hydrocarbon plume and the unconfined aquifer beneath the site. It is highly unlikely that the petroleum hydrocarbon plume will ever migrate to the groundwater. The nearest drinking water well (California Water Service Station 78-01) to the plume area is over 500' north (upgradient) and completed in a zone hundreds of feet deeper than the base of the plume. The source of the petroleum hydrocarbon plume, the former UST's and solvent dispenser, have been removed and will not continue to add to the plume. The levels of benzene are low in the soil especially in the top 30' bgs. (all ND), with the likely elevated cancer risk to the on-site employees very low. If the petroleum hydrocarbons are left in-place they will continue to bio-degrade over-time further reducing any current environmental risks. The hydrocarbon plume does not appear to be a significant threat to the groundwater beneath the site or to on-site workers. As part of this remedial action alternative SEI recommends an asphalt cover be placed over the former UST area to prevent water infiltration and minimize the potential for the hydrocarbon plume to migrate deeper. If necessary, a detailed Risk Assessment will be prepared fully evaluating the risks to the groundwater and to on-site workers. Costs for this alternative are less than $10,000. SEI recommends this remedial alternative. Excavation of Petroleum Hydrocarbon Plume The petroleum hydrocarbon plume extends to a depth of approximately 60 feet bgs. near boring B-2 and is in a confined area between the railroad tracks to the south and the aboveground tanks to the east. An excavation to a depth of 60' bgs. with a diameter of at least 30' in the area of borings B-2 and B-3 would not be feasible. The stability of the aboveground tanks and pumps to the east would be compromised and the railroads tracks to the south may be impacted by an excavation of this extent. Estimated cost for this type of excavation with extensive shoring of the SOILS ENGINEERING, INC. Site Characterization Report File Number 99-9015 900 Sacramento St.., Bakersfield, CA. October 28, 1999 Schwebel Petroleum Page 5 ¢o~ sidewalls on the east and south would be well over $100,000. Based on the above information this remedial alternative is not recommended for this site. Vapor Extraction of Petroleum Hydrocarbons petroleum hydrocarbon plume at may The the site removed extraction. This would involve the installation of ntultiple vaI depths of 40' to 60' bgs. in the area of soil borings ]i-2, B-3 of silt from 25' to 35' and 40' to 80' it may be difficult to ex vapor extraction.

Operation and maintenance of the vapor' extractim approximately 6 to 12 months. After va,por con~:entrations con£u-mation soil borings (at least 3 to 60 bgs.) ~vould be analyzed for TPHg, TPHd, and BTEX to evaluate th e reductioi the soil after vapor extraction. If the analytical rest lts indicat( closure of the site would be recommended. Estimated cost for vapor extraction system for a period of 1 year would be $90,00. RECOMMENDATIONS SEI recommends the implementation of the natural attenuation remedial alternative with the placement of an asphalt over the in-place petroleum hydrocarbon plume. cap SEI recommends that remedial alternatives for the former waste oil tank area be included in a the DTSC. A of this and closure will also be submitted the separate report tO copy report plan tO BFDES. o o Please call Soils En=ineerin~, Inc. at (661) 831-5100 if you have any questions concerning this Report. Sincerely, Robert J. Becker, R.G. Environmental Division Manager~ The petroleum hydrocarbon plume at the site may be removed by the remedial alternative vapor This would involve the installation of multiple vapor extraction wells (at least 5) to depths of 40' to 60' bgs. in the area of soil borings B-2, B-3 and B-5. Since there is a great deal of silt from 25' to 35' and 40' to 80' it may be difficult to extract the plume cost effectively by A vapor extraction pilot test (VET) would be performed on the vapor extraction wells (VEW's) to determine the effectiveness of vapor extraction at this location and to determine the appropriate flow rates, size and type of vapor extraction unit. If the VET shows that vapor extraction would be effective at the site, an authority to construct (ATC) permit would be acquired from the Kern County air pollution control district (APCD). Once the ATC permit is approved, vapor extraction piping connecting the VEW's to the vapor extraction system would be Operation and maintenance of the vapor extraction system would be conducted for After vapor concentrations have been reduced significantly, con£u-mation soil borings (at least 3 to 60' bgs.) would be drilled with collected soil samples analyzed for TPHg, TPHd, and BTEX to evaluate the reduction of the petroleum hydrocarbons in If the analytical results indicate a significant reduction in the soil Estimated cost for the installation and operation of a vapor extraction system for a period of 1 year would be $90,000 to $120,000.
