(SEI) following the completion of field activities and the receipt of analytical test results at the former hazardous waste storage area of Schwebel Petroleum Company Bulk Plant located at 900 Sacramento Street in Bakersfield, CA. (site). SEI advanced 1 soil boring to a depth of 40 feet in the area of the former 550-gallon hazardous waste oil underground storage tank (UST) 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) and the Department Of Toxic Substance Control (DTSC). 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 DTSC has requested a closure plan be prepared for the hazardous waste storage area. I A separate Site Characterization Report has been prepared by SEI for the 6 fuel UST's dated October 28, 1999.

File Number 99-9015 November 1, 1999 Page 2 I I i I I I I I I I I I I I I SCOPE OF WORK CONDUCTED Drilling of Soil Boring BI to 40' SEI utilized an SEI owned and operated Hollow-stem auger drill rig to advance 1 soil boring to a depth of 40 feet below ground surface (bgs) at the former hazardous waste oil UST location. Five additional soil borings were advanced in the area of the former fuel UST's as shown on the attached Plot Plan (Plate 2). A California registered geologist supervised the drilling process. Soil boring B-1 was initially advanced to a depth of 20' bgs. on September 1, 1999. On September 24, 1999 the boring was advanced an additional 20' to a depth of 40' bgs.. 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-1) was collected from the stockpiled cuttings and analyzed for profiling purposes prior to disposal/recycling activities. Analytical Testing Selected soil samples from the soil boring 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 BI-10' was analyzed for purgeable halocarbons by EPA Method 8010, and CAM 17 Metals. 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 soil boring B 1 consisted of fill in the top 5 feet, underlain by silty sand (SM) and well graded sand (SW) to a depth of approximately 29' bgs.. A Silt (ML) was encountered from a depth of 29' to a depth of approximately 40 ' bgs.. Petroleum stained soil and odor was encountered in boring B-1 from the surface to approximately 13' bgs.. No petroleum staining or odor was present from approximately 13' to 40' bgs.. The highest PID reading was recorded in boring B-1 at 5' (1500 parts per million (ppm)) and 10' (1450 ppm).. PID readings decreased significantly at a depth of 15' bgs. with the highest PID I I I I I I i I I I I I I I I I I Site Characterization Report & Closure Plan 900 Sacramento St.., Bakersfield, CA.

See attached Boring Log in Appendix B for more detail. Analytical Results of Soil Samples The analytical results of the selected soil samples analyzed from the soil boring B- 1 are presented on Table 1. The analytical results indicate detectable petroleum hydrocarbons are present from near surface to approximately 20' bgs.. The highest hydrocarbon concentration reported was 24,400 ppm TPHd at 10'. No benzene concentrations were reported in any of the 5 soil samples analyzed from boring B-1. No significant MTBE concentrations were reported in any of the soil samples analyzed. Soil sample B 1-10' had 105 parts per billion (ppb) tetrachloroethene reported. Metal concentrations were in the normal range for soil sample B 1-10' and for the composite soil sample ROB-1 from the stockpiled soil cuttings. See attached analytical reports in Appendix A. Disposal of Soil Cuttings The soil cuttings in the roll-off bin were disposed of as non-hazardous Corporation in Bakersfield, CA.. See attached non-hazardous manifest. waste at SoilRem CONCLUSIONS Based on f'teld observations and soil sample analytical results SEI concludes the following: 1) Detectable petroleum hydrocarbons are present in soil from near surface to approximately 20 feet bgs. at soil boring B- 1 in the central area of the former waste oil UST. Below a depth of 13' bgs. the petroleum hydrocarbon staining and odor decrease significantly. The lateral extent of the petroleum hydrocarbon plume is estimated at less than 15' in diameter. Benzene concentrations in soil samples were all less than the detection limit (<5 ppb) in the soil samples. 2) The majority of the petroleum hydrocarbo,n plume is apparently in the diesel fuel range with some gasoline range constituents reported in the top 10'. The highest TPHd result is 24,400 ppm at 10' and the only TPHg result above detection limits is 615 ppm at 10' in boring B-1. 3) Depth to groundwater in this area as reported by the Kern County Water Agency is approximately 220' bgs. or approximately 200' below the base of the TPHd plume at B-1. If the most significant portion of the hydrocarbon plume is removed (top 15') it is highly unlikely that the remaining residual hydrocarbons will be a threat to the groundwater beneath the site or to on-site workers. 4) The nearest public drinking water well (currently inactive) is over 500' north (upgradient) of the site and is not threatened by this plume.

I ! I I I I I ! CLOSURE PLAN The following is a Closure Plan for the permanent closure of the hazardous waste storage area. Introduction The 550-gallon hazardous waste oil UST and drum storage area were removed in August, 1998 from the site. The UST was properly decontaminated with the resulting rinsate disposed of as Non-RCRA hazardous waste at an approved facility. After decontamination the UST was removed and disposed/recycled at an approved facility. Soil samples collected beneath the former waste oil UST indicated elevated petroleum hydrocarbons were present beneath the former UST location. Site characterization activities conducted during this investigation indicate that detectable petroleum hydrocarbons extend to a depth of approximately 20' bgs. with an estimated lateral extent of approximately 15'. Excavation of Petroleum Hydrocarbon Plume Detectable petroleum hydrocarbons extend to a depth of approximately 20 feet bgs. beneath the former hazardous waste oil UST. Since the top 13' of soil is significantly stained and contains the highest concentrations of TPHd and TPHg an excavation to a depth of 15' bgs. with a diameter of approximately 15' in the area of the former hazardous waste oil UST is recommended. A backhoe or excavator should be utilized to remove an estimated 125 cubic yards (190 tons) of petroleum hydrocarbon impacted soil. The sidewalls of the excavation should be sloped to ensure adequate stability of the excavation during removal activities. The area should be fenced to prevent unauthorized entry during excavation activities. Once the majority of the petroleum hydrocarbon plume is removed with no significant staining or odor remaining, bottom and sidewall samples should be collected to evaluate the remaining petroleum hydrocarbons within the excavation. The remedial goals proposed for this site will be TPHd less than 5,000 ppm, TPHg less than 100 ppm, and benzene less than 1 ppm. Soil samples (estimated at 5) will be analyzed for TPHd, TPHg, and BTEX & MTBE by an on-site mobile laboratory or on a fast turnaround at a local laboratory. Once these remedial goals are achieved the excavation will be backfilled and compacted with clean fill up to match existing grade. An asphalt cap will be placed over the excavation to prevent water infiltration. Disposal Of Petroleum Impacted Soil The removed soil will be placed on and covered with plastic. The soil will be profiled for recycling/disposal and transported under a non-hazardous manifest to a licensed non-hazardous waste facility, which accepts the profiled soil. I I SOILS ENGINEERING, INC. I Site Characterization Report & Closure Plan File Number 99-9015 900 Sacramento St.., Bakersfield, CA. November I, 1999 I SchwebeI Petroleum Co. Page 5 Reporting IA Closure Report will be completed describing the field work conducted with analytical results of soil samples, non-hazardous waste manifests, and conclusions and recommendations for the site. Estimated cost for this type of excavation is less than $25,000. I Health & Safety Plan All employees that will work at the site will have received the Health and Safety training required I by OSHA for hazardous waste site operations (29 CFR 1910.120). Diesel and fuel gasoline constituents are the identified hazardous substances at this site. Highly volatile components, such as benzene, pose the greatest health hazard. Because of the outdoor location and the intermittent I operations, not likely that personnel will be exposed to nature of excavation it considered elevated levels of hydrocarb.o,n vapors for any length of time. Under these conditions personnel will work under "Class D' protection. A PID or FID will be used to monitor ambient I concentrations of organic vapors. Personnel will have access to air-purifying respirators (APR) with organic vapor canisters that can be donned if conditions warrant. I detailed site specific Health and Safety Plan, will be distributed to and adhered to by all A contractor personnel, subcontractors, and all site visitors. A "tailgate' safety meeting will be held i at the site prior to commencing operations during which all site hazards and the Health and Safety Plan will be reviewed. See attached Health & Safety Plan (Appendix C).

SECTION 1 FACILITY BACKGROUND 1.1 SITE DESCRIPTION The Schwebel Petroleum bulk plant is located at the southeast corner of the intersection of South Union Avenue and Watts Drive in Bakersfield, CA.. The site is a bulk plant for the storage of petroleum hydrocarbon products such as oils and lubricants. Six (6) six- thousand gallon underground storage tanks (UST's) were located west of the aboveground storage tanks, along with a 550 gallon waste oil UST on the western portion of the site. 1.2 SITE HISTORY 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). See attached Table 1 for analytical results of soil samples collected beneath the UST's, and product piping which was conducted by Holguin, Fahan & Associates (HFA). See Plate 3 for sample locations (HFA). 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. In September, 1999 SEI advanced 6 soil borings at the site collecting soil samples for analytical testing. Hydrocarbon plumes are present beneath the former waste oil UST to a depth of approximately 20' and beneath the east-central area of the former fuel UST's between 30' to 60' bgs.. PROPOSED SCOPE OF WORK Excavation of Hydrocarbon Impacted Soil Detectable petroleum hydrocarbons extend to a depth of approximately 20 feet bgs. beneath the former hazardous waste oil UST. Since the top 13' of soil is significantly stained and contains the highest concentrations of TPHd and TPHg an excavation to a I I I !

File No. 99-9015 November, 1999 Page No. 2 I I I I I I I I I I I I I I I depth of 15' bgs. with a diameter of approximately 15' in the area of the former hazardous waste oil UST is recommended. A backhoe or excavator should be utilized to remove an estimated 125 cubic yards (190 tons) of petroleum hydrocarbon impacted soil. The sidewalls of the excavation should be sloped to ensure adequate stability of the excavation during removal activities. The area should be fenced to prevent unauthorized entry during excavation activities. Once the majority of the petroleum hydrocarbon plume is removed with no significant staining or odor remaining, bottom and sidewall samples should be collected to evaluate the remaining petroleum hydrocarbons within the excavation. The remedial goals proposed for this site will be TPHd less than 5,000 ppm, TPHg less than 100 ppm, and benzene less than 1 ppm. Soil samples (estimated at 5) will be analyzed for TPHd, TPHg, and BTEX & MTBE by an on-site mobile laboratory or on a fast turnaround at a local laboratory. Once these remedial goals are achieved the excavation will be backfdled and compacted with clean fdl up to match existing grade. An asphalt cap will be placed over the excavation to prevent water infiltration. Disposal Of Petroleum Impacted Soil The removed soil will be placed on and covered with plastic. The soil will be profiled for recycling/disposal and transported under a non-hazardous manifest to a licensed non- hazardous waste facility, which accepts the profiled soil. PROJECT SCHEDULE AND WORK PLAN 2.1 PROJECT SCHEDULE The field activities will follow those outlined in the attached Site Characterization Workplan. They are scheduled to be completed within one to two working days followed by a Site Characterization Report describing the findings of the field work. 2.2 WORK PLAN At least 48 hours prior to conducting the field work, Soils Engineering, Inc. (SEI) will notify the DTSC & BFDES of the time and date. An estimated 200 tons of hydrocarbon impacted soil will be removed and disposed of per regulatory requirements. A Closure Report will be prepared detailing the field work performed, analytical results, plot plans, with conclusions and recommendations for the site. I I i I I I ! I I I I I !

Engineering and administrative I I I 1 Site-Specific Health & Safety Platt Schwebel Petroleum Co. 900 Scaramento St., Bakersfield, CA. SOILS ENGINEERING, INC. File No. 99-9015 November, 1999 Page No. 5 I I I I I I I I I I I I I I I controls will be employed if required to abate windbome dust. These will include items such as water spray and/or administrative controls such as reducing site activities that produce windborne dust. 4.3 DERMAL EXPOSUREHAZARD Contact of sufficient duration to cause significant absorption of toxic components is highly unlikely. Repeated daily or prolonged contact over a period of time may however, lead to absorption through the skin, irritation and dermatitis. For this reason direct skin contact shall be avoided by wearing protective gloves and clothing. However, if contact does occur, the exposed areas shall be washed with soap and water and rinsed thoroughly. 4.3.1 Eye Contact If eye contact is made with any chemical materials at the site, the eye shall be flooded with water for at least 15 minutes. Medical attention shall be obtained as soon as possible. 4.3.2 Skin Contact Skin exposure shall be treated by washing with soap and water. Any contaminated clothing shall be removed and affected areas washed with soap and water. 4.4 OTHER HAZARDS Attention must be paid to other possible hazards on the site including, but not limited to: - improper use of hand tools - rotating machinery such as pumps - dehydration of the personnel - tripping on objects or open ditches - falling objects from the overhead work - lack of oxygen through blockage of the mask - overhead power lines 4.5 HEAT STRESS PREVENTION The SSO shall monitor ambient temperature and use the following work/rest regimes as a guide.

File No. 99-9015 November, 1999 Page No. 6 I I I I I I I I I I I I I I I For ambient temperature below 80°F, standard rest breaks (e.g. 15 minutes every 4 hours) should be used. For temperature above 80°F, the following regime should be followed. Temperature Work Rest Comments (a) 80 to 85°F 2 hr. 5 min. Review heat stress in a safety meeting. Schedule a beverage break every 2 hrs., at a minimum. 80 to 90°F 2 hr. 15 min. Seated rest. Drink at least 8 ounces at each break. Above 90oF 1.5 hr 15 min. As stated above. Rest area to be shaded. SECTION 5 JOB HAZARD SUMMARY Exposure to chemical hazards may occur when contaminated soils are brought to the surface during excavation activities. As each of task begins, the potential risk of exposure increases. Consequently, level C personal protective equipment shall be available at the site. If monitoring of the breathing zone establishes another action level, the personal protection level may be upgraded. Nearby residents or workers are at a sufficient distance that they shall be at no significant risk. The SSO shall determine if any further action is required. SECTION 6 EXPOSURE MONITORING PLAN 6.1 DRILLING The exposure monitoring activities shall be conducted or directed by the SSO during those activities that require such monitoring. At a minimum, the breathing zone shall be monitored for organic vapors during drilling activities. This shall be accomplished by use of a Foxboro OVA, HNU or Photovac PID portable analyzer. A Gastech LEL explosive meter shall be used to warn of any explosive hazards during these activities.

File No. 99.9015 November, 1999 Page No. 7 I I I I I I I I I I I I I I ! 6.2 ACTION LEVELS Action levels for explosive hazards are set at 25% of the lower explosive limit (LEL). In the event that enough combustible vapor is present to sustain readings at or near 25% of LEL work shall cease until an evaluation is perform by the SSO and a determination can be made. Action levels for organic vapors in the breathing zone shall be based on readings obtained by the portable equipment mentioned. The PID instrument determines the total organic vapor present in the breathing zone. Readings of 0 to 300 ppm (TWA for gasoline is 300 ppm)shall be considered level D without respirators. Readings of 300 ppm or greater for 5 minutes or longer shall trigger an action level to upgrade to level C or modified level D with respirators. SECTION 7 PERSONAL PROTECTIVE EQUIPMENT The respiratory and skin protection requirement shall be initially set at level "D" without respirators. This indicates that inhalable airborne substances are known, and concentrations of chemicals in the atmosphere are not expected and are well below TLV- STEL levels. The use of the f6'iliS~ing personal protection equipment is mandatory. 7.1 EQUIPMENT REQUIRED FOR FIELD PERSONNEL - Hard hat - Boots (with steel toes) Nitrile, or equivalent, work gloves - Eye protection 7.2 LEVEL C PERSONAL PROTECTIVE EQUIPMENT - Half-mask air purifying respirator necessary. - Tyvek protective coveralls - Gloves (latex and/or Nitrile) with organic vapor cartridge when 7.3 EQUIPMENT TO BE USED OR AVAILABLE ON SITE: - First-aid kit with eyewash I I I I SOILS Site-Specific Health & Safety Plan Schwebel Petroleum Co. 900 Scaramento St., Bakersfield, CA.

Work areas shall be delineated to protect the general public from exposures and hazards. If level C protection becomes necessary then zones and access points shall be clearly indicated. A restricted area for contamination reduction shall be maintained at the exit to the exclusion zone. Protective clothing and equipment as required by this health and safety plan shall be worn at all times in the exclusion zone and shall only be removed in the designated decontamination corridor at the exit. The areas outside the contamination reduction area, is considered a clean area. SECTION 9 DECONTAMINATION PROCEDURES Decontamination of equipment shall be conducted when necessary. However, if it becomes necessary to upgrade to a protect level greater that "D", then an Exclusion Zone shall be established and an area in the Contamination Reduction Corridor (CRC) shall be used as a decontamination area. The CRC controls access into and out of the Exclusion Zone and confines personnel and equipment decontamination activities to a limited area.
