(World), The Source Group, Inc. (SGI) is pleased to submit this Annual Remediation Summary Report for the former Sunland Oil Refinery located in Bakersfield, California ' (Figure 1). The remediation data obtained and monitoring activities conducted during January 1, 2009 through December 31, 2009 are summarized in this report. INTRODUCTION This report has been prepared pursuant to the "Final Judgment Pursuant to Stipulation" (KCSC No. ' 228 399-RA). The Final Judgment directs Sunland Refining Corporation to comply with the California Regional Water Quality Control Board —Central Valley Region's (CVRWQCB) Cleanup and Abatement Order (CAO) No. 95-702 dated April 27, 1995. Item 8 of the Final Judgment requires the submittal of an annual summary regarding the status of site remediation efforts to ' contain and remediate groundwater. and soil impacted by petroleum hydrocarbons under CAO No. 95-702. ' The former Sunland Refinery site is divided into three main areas: the former West Tank Farm (WTF), the former refinery plant/former South Tank Farm (STF), and the former North Tank Farm (NTF) (Figure 2). EXECUTIVE SUMMARY ' Based on a review of the remedial activities performed during this reporting period, the following summary and conclusions are presented: ' Remedial Activities — From January 1, 2009 through December 31, 2009, the high capacity vapor extraction system (HCVES) removed approximately 522 tons of total petroleum hydrocarbon (TPH) mass and 4.6 tons of methyl tertiary butyl ether (MtBE) from the subsurface. A cumulative total of 4,474 and 26 tons of hydrocarbons and MtBE, respectively, have been removed to date. Approximately 1,650 gallons of liquid phase hydrocarbons (LPH) were removed during the reporting period as vapor condensate. 299 West Hillcrest Drive Telephone: (805)373-9063 Suite 220 Facsimile: (805)373-9073 Thousand Oaks, California 91360 e-mail: mlabrenz @thesourcegroup.net Mr. John T. Mitchell, Kern County District Attorney's Office March 31,2010 Annual Remediation Summary Report(2009) Page 2 1 Assessment Activities — On February 19, 2009, SGI submitted a workplan to the CVRWQCB for ' the installation of four additional groundwater monitoring wells (TSG-MW-1 17A/B/C/D) to be installed approximately 1,000 feet to the west_northwest of existing monitoring well TSG-MW-115. The well installation was conditionally approved by the CVRWQCB in a letter to World dated June 12, 2009. World is continuing to work with the property owner to finalize an access agreement prior to installing the wells. ' REMEDIAL ACTIVITIES FOR 2009 Remedial activities at the former Sunland Refinery facility began on March 22, 1996 following the ' installation of a vapor extraction system and an air sparging system. The vapor extraction and air sparging systems were operated at the STF until June 19, 1998 and at the WTF until July 30, 1998. Installation of a HCVES (utilizing a John Zink flare as an abatement device) replaced the former ' vapor treatment system and operation of the HCVES and AS systems started on September 16, 1998. A Baker Furnace thermal oxidizer and 4,000-gallon above ground storage tank were added to the STF remediation compound in early 2005. Following completion of oxidizer installation in April of ' 2005, system operation began With the thermal oxidizer as the main abatement device in early May 2005. Due to dropping water levels, which has increased the soil column available to soil vapor extraction (SVE), hydrocarbon mass removal rates have increased, necessitating switching ' abatement devices from the thermal oxidizer to the John Zinc flare. The switch from the thermal oxidizer to the flare took place on May 29, 2009. Figure 3 shows the layout of existing remediation wells and the treatment compound locations. ' System Operations and Monitoring ' During the reporting period (January 1, 2009 through December 31, 2009), remedial operations were performed in accordance with the requirements contained in the operational permit(s). During the reporting period, the HCVES removed approximately 522 tons of petroleum hydrocarbons and 4.6 tons of MtBE. A cumulative total of 4,474 tons of hydrocarbons and 26 tons of MtBE have been ' removed to date (Figures 4 and 5). HCVES operations for the reporting period are summarized in Appendix A. ' Due to dropping water levels, which has increased the soil column available to SVE, hydrocarbon mass removal rates have increased, necessitating switching abatement devices from the thermal oxidizer to the John Zinc flare. The switch from the thermal oxidizer to the flare took place on May ' 29, 2009. A letter to the San Joaquin Valley Air Pollution Control District (SJVAPCD) was submitted on June 3, 2009, documenting the change in abatement device use. SGI operated the HCVES utilizing the John Zinc flare as the primary abatement device through the second half 2009 reporting ' period. Approximately 1,650 gallons of LPH were removed during the reporting period as vapor condensate associated with the operation of the HCVES and manual bailing from wells TSG-SVE-120 and -121. All extracted liquids were transported by Asbury Environmental Services to Demenno Kerdoon in Compton, California for disposal/recycling. The total volume of LPH removed since December 1996 ' is approximately 16,849 gallons. LPH removal activities are summarized in Appendix A. Due to dropping water levels, selected air sparge well casings were modified to accommodate soil vapor extraction and tied via above ground vapor conveyance lines to the HCVES. The deep ' The Source Group,Inc. ' Mr. John T. Mitchell, Kern County District Attorney's Office March 31,2010 Annual Remediation Summary Report(2009) Page 3 sparge casing from air sparge wells SE-AS-30, SE-AS-31, AS-77, AS-78, AS-79, and AS-80, as well ' as the sparge casing from dual purpose wells ASNE-73, ASNE-74, and ASNE-76 were converted to allow soil vapor extraction. Well modification was completed on June 10, with system restart on June 12, 2009. ' Air sparging was used for the remediation of dissolved phase hydrocarbons as well as the enhancement of vapor phase hydrocarbon recovery. Wells SE-AS-30, SE-AS-31, SE-ASNE-45, ' SE-ASNE-46, TSG-ASNE-52, TSG-ASNE-53, TSG-ASNE-54, TSG-ASNE-55, GMX-ASNE-63, GMX-ASNE-64, GMX-ASNE-65, AS-73, AS-76, AS-77, AS-78, AS-80, AS-81, TSG-AS-86, TSG- AS-87, TSG-AS-88, TSG-AS-89, TSG-AS-103, TSG-AS-104, TSG-AS-105, TSG-AS-106, TSG-AS- 107 and TSG-AS-108 were all employed in air sparging during the reporting period. ' During second quarter 2009, SGI discontinued air sparging at the former WTF and former STF areas of the Sunland site, as well as the PG&E property north of the railroad tracks due to dropping ' groundwater levels. Currently installed sparge wells are screened at levels that currently do not encounter groundwater. ' Monitoring of subsurface conditions was performed periodically during weekly operation and maintenance (O&M) of the HCVES as well as during periods of LPH removal and during semi- annual groundwater gauging and sampling. During HCVES operation, weekly O&M activities included measuring.extraction flow rates, total system influent hydrocarbon concentrations in the vapor stream, system vacuum, processing temperatures and utility usage for electricity and supplementary natural gas. Selected individual remediation wells were monitored approximately once a month for groundwater and product levels, hydrocarbon concentrations in the vapor stream, and vacuum. Vapor samples were collected from the inlet header(s) for laboratory analysis once a month. From weekly data and monthly data, the system was adjusted to optimize the removal of subsurface contaminants. ASSESSMENT ACTIVITIES FOR 2009 ' On February 19, 2009, SGI submitted a workplan to the CVRWQCB for the installation of four additional groundwater monitoring wells (TSG-MW-1 17A/B/C/D) to be installed approximately 1,000 ' feet to the west-northwest of existing monitoring well TSG-MW-115. The proposed wells will be installed as a well cluster (individual wells installed into separate boreholes drilled approximately five feet apart) with the objective of defining the lateral as well as vertical extent of hydrocarbon constituents [total petroleum hydrocarbons as gasoline (TPHg), benzene, and MtBE] in groundwater downgradient of the former Sunland Refinery site. On April 17, 2009, World received correspondence from the CVRWQCB requesting additional information be provided regarding well ' installation. On May 22, 2009, SGI submitted a Revised Well Installation Workplan to the CVRWQCB for the installation of the above referenced wells. The Revised Well Installation Workplan was conditionally approved by the CVRWQCB in a letter to World dated June 12, 2009. ' World issued a letter to the property owner on June 24, 2009 requesting permission to access the property (APN 368-010-13), west of the PG&E Former Kern Power Plant for the purpose of installing monitoring well cluster TSG-MW-1 17A/B/C/D. World and the owner of the offsite property (APN ' 368-010-13) were in negotiations throughout the remainder of 2.009 regarding the access agreement for well installation. ' The Source Group,Inc. ' Mr. John T. Mitchell, Kern County District Attorney's Office March 31, 2010 Annual Remediation Summary Report(2009) Page 4 ' On May 15, 2009, SGI installed Bio-Trap samplers into wells TSG-MW-20D and TSG-MW-115B in order to conduct microbial testing to confirm that in-situ biodegradation of MtBE and tert-butanol (tBA) may occur in groundwater underlying the site. The Bio-Trap samplers were retrieved on June ' 30, 2009. Analysis of the results from the Bio-Trap samples is in progress. On September 18`h, 2009, SGI submitted a workplan for the installation of four additional SVE wells ' to be installed within the former South Tank Farm/Refinery area. The workplan was approved br the CVRWQCB in a letter to World dated October 12, 2009. During the period November 16 through November 23rd, 2009, four new SVE wells (TSG-SVE-118 through TSG-SVE-121) were installed to supplement existing SVE wells and to allow soil vapor extraction within newly exposed vadose zone at a depth from 120 feet to approximately 150 feet bgs. The new wells were additionally screened approximately 20 feet into groundwater to accommodate a potential further decrease in groundwater elevation. The wells can additionally be used as groundwater monitoring ' points to monitor groundwater conditions within the source area. The four new wells were tied into the HCVES between December 7 and December 11, 2009. ' GROUNDWATER MONITORING ' Groundwater monitoring and sampling events were performed in March and October 2009. Groundwater monitoring well locations are depicted on the site map included as Figure 2. The groundwater elevation data and analytical results for the two sampling events are summarized in ' Tables 1, 2, and 3. Over the reporting period, the calculated groundwater gradient ranged from 0.003 feet/foot to 0.004 ' feet/foot to the west and west-southwest, which is similar with the gradient measured in previous years. Groundwater data, summarized in the 2009 Semi-Annual Groundwater Monitoring and Status Reports, are presented in Appendix B. Groundwater contour and hydrocarbon concentration maps for 2008 are included in Appendix C. SCHEDULE ' Operation of the remediation system and semi annual groundwater monitoring will continue in 2010. The next groundwater monitoring and sampling event is scheduled for March 2010. 1 ' The Source Croup,Inc. Mr.John T.

Wayne Perry, Inc. (WPI)measured groundwater(and liquid petroleum hydrocarbon [LPH] levels,when present)in the groundwater monitoring wells on March 16, 2009. ' 2. WPI purged and sampled.on-and off-site groundwater monitoring wells on March 17 through 20, 2009 and May.21,2009. Purge water was temporarily stored on site and subsequently transported to DeMenno /Kerdoon for recycling. Dissolved oxygen(DO)and oxidation-reduction potential(ORP)were additionally measured during purging of select wells as part of the ongoing natural attenuation study. During the initial ' sampling event of March 17 through 20,2009,groundwater samples from wells TSG-MW-114A-C,TSG- MW-115A-C, and TSG--MW-116A-C were to be analyzed for ethanol and methanol. However, due to a sampling oversight, these analytes were not included for analysis. Wells TSG-MW-1 14B/C,TSG-MW- ' 115C, and TSG-MW-1 16B/C were re-purged by WPI on May 21, 2009 and sampled for ethanol and methanol. The A-casings for each of the aforementioned wells were dry during the first half 2009 sampling event and were therefore not sampled. Groundwater from well TSG-MW-115B was additionally not sampled for ethanol nor methanol during the first half 2009 sampling event due to the fact that a Bio- ' Trap sampler was installed within this well on May 15, 2009, precluding the collection of a groundwater sample during the May 21,2009 sampling event. 3. SGI operated the high capacity vapor extraction system (HCVES) utilizing the Baker Furnace thermal oxidizer as the primary abatement device through the first half 2009 reporting period. 4. SGI continued air sparging at the former West Tank Farm (WTF)and former South Tank Farm (STF) ' areas of the Sunland site, as well as the PG&E property north of the railroad tracks. 5. On February 19, 2009,SGI submitted a workplan to the CVRWQCB for the installation of four additional groundwater monitoring wells(TSG-MW-1 17A/B/C/D)to be installed approximately 1,000 feet to the west- , northwest of existing monitoring well TSG-MW-115. The proposed wells will be installed as a well cluster (individual wells installed into separate boreholes drilled approximately five feet apart)with the objective of defining the lateral as well as vertical extent of hydrocarbon constituents[total petroleum hydrocarbons as ' gasoline (TPHg), benzene, and methyl tertiary butyl ether (MtBE)] in groundwater downgradient of the former Sunland Refinery site. On April 17,2009,World received correspondence from the CVRWQCB .requesting additional information be provided regarding well installation. A Revised Well Installation Workplan was submitted to the CVRWQCB on May 22, 2009. ' 6. On May 15,2009,SGI installed Bio-Trap samplers into wells TSG-MW-20D and TSG-MW-115B in order to conduct microbial testing to confirm that in-situ biodegradation of MtBE may occur in groundwater underlying the site. 299 West Hilicrest Drive Telephone: (805)373-9063 ' Suite 220 Facsimile: (805)373-9073 Thousand Oaks, California 91360 e-mail: miabrenz@thesourcegmup.net ' Date: June 1, 2009 WORK PROPOSED FOR NEXT PERIOD (June 2009 through December 2009): ' 1.

' Date: June 1 2009 ' GROUNDWATER MONITORING PROCEDURES FORMER SUNLAND OIL REFINERY 2152 Coffee Road, Bakersfield, CA 1 Groundwater Gauging. Each well was located and inspected prior to gauging by Wayne Perry, Inc. (WPI). Using a Solinstr oil/water interface probe, each well was then gauged for depth to ' groundwater, depth to liquid-phase hydrocarbons (LPH) if present, and total well depth (if no LPH was present). Gauging devices were decontaminated between each well using a triple-rinse method of tap water with non-phosphate detergent, tap water, and then deionized water. The sampling ' sequence was based on the analytical results obtained during the previous sampling event. Wells showing petroleum hydrocarbon sheen during gauging or purging were sampled only if sheen was not observed following purging and recovery. Wells containing floating product were not sampled; ' however, the thickness of floating product in LPH affected wells was measured and recorded. Groundwater Purging and Sampling. Groundwater monitoring wells were purged and sampled by ' WPI. Wells were purged of water using either a PVC bailer,electric pump, or micro-purged using a RediFlow pump. Fast recharging wells were purged of three well casing volumes of water. Slow recharge wells were purged until dry and allowed to recover for two hours or until the well recovered ' 80 percent of the initial water column height before sampling. During purging, water parameters including pH, temperature, conductivity, and turbidity were monitored to ensure stabilization within 10% of each parameter and ensure that groundwater representative of the aquifer was entering the well. Additionally some groundwater monitoring wells were also measured for dissolved oxygen ' (DO) and oxygen reduction potential (ORP) using a field monitoring device. DO and ORP were measured through a flow cell during both the beginning of purging (identified as pre-purge)as well as at the end of purging (identified as post-purge). ' The bailer used for well purging was decontaminated between each well using a triple-rinse method of tap water and non-phosphate detergent, tap water, and then deionized water. The pump was ' decontaminated by cycling the washwater through the pump followed with a deionized water rinse. Groundwater samples were collected using a polyethylene disposable bailer attached to new nylon cord. Samples were transferred to containers provided by the laboratory appropriate to the analysis ' to be performed. The containers were capped with TeflonTm septa, labeled, and placed on ice for transport to State-certified American Analytics,of Chatsworth, Califomia. New sampling equipment (nylon cord, bailer, etc.)was used on each well to deter potential cross-contamination. ' Quality Assurance/Quality Control (QA/QC)Samples. Quality control samples submitted to the laboratory included one laboratory-prepared trip (or travel) blank. One trip blank was kept in the ' sample cooler and submitted to the laboratory with the groundwater samples. WPI initiated a Chain- of-Custody record in the field immediately following sample collection to accompany the samples to the laboratory. ' Liquid-Phase Hydrocarbon (LPH) Removal. LPH is removed from wells using one of the following methods: • Flexible PVC stingers that extract the LPH via airlift created by the vacuum extraction ' blower; • Bailing of affected wells; or Vacuum truck service. ' Waste Disposition. Purge water generated during this monitoring event was removed by vacuum truck and transported under manifest to DeMenno/Kerdoon in Compton. First half 2009 waste recycling/disposal documentation is provided within Appendix D of this report. t1 The Soume Group,Inc. 1 ' SEMI-ANNUAL GROUNDWATER MONITORING AND STATUS REPORT SECOND HALF-2009 ' Client: World Oil Corp.

Wayne Perry, Inc. (WPI)measured groundwater(and liquid petroleum hydrocarbon [LPH]levels, when present)in the groundwater monitoring wells on October 5, 2009. 2. WPI purged and sampled on-and off-site groundwater monitoring wells on October 6 through October 9, ' 2009. Purge water was temporarily stored on site and subsequently transported to DeMenno/Kerdoon for recycling. Dissolved oxygen(DO)and oxidation-reduction potential(ORP)were additionally measured during purging of select wells as part of the ongoing natural attenuation study. ' 3. Due to dropping water levels,which has increased the soil column available to soil vapor extraction(SVE), hydrocarbon mass removal rates have increased, necessitating switching abatement devices from the thermal oxidizer to the John Zinc flare. The switch from the thermal oxidizer to the flare took place on May 29, 2009. A letter to the San Joaquin Valley Air Pollution Control District(SJVAPCD)was submitted on June 3,2009, documenting the change in abatement device use. SGI operated the high capacity vapor extraction system (HCVES) utilizing the John Zinc flare as the primary abatement device through the second half 2009 reporting period. t4. Due to dropping water levels,selected air sparge well casings were modified.to accommodate soil vapor extraction and tied via above ground vapor conveyance lines to the HCVES. The deep sparge casing ' from air sparge wells SE-AS-30, SE-AS-31, AS-77, AS-78, AS-79, and AS-80, as well as the sparge casing from dual purpose wells ASNE-73,ASNE-74, and ASNE-76 were converted to allow soil vapor extraction. Well modification was completed June 10, with system restart on June 12, 2009. 5. During second quarter 2009, SGI discontinued air sparging at the former West Tank Farm (WTF)and ' former South Tank Farm (STF) areas of the Sunland site, as well as the PG&E property north of the railroad tracks due to dropping groundwater levels. Currently installed sparge wells are screened at levels that currently do not encounter groundwater. ' 6. On May 15,2009,SGI installed.Bio-Trap samplers into wells TSG-MW-20D and TSG-MW-115B in order to conduct microbial testing to confirm that in-situ biodegradation of MtBE and 1BA may occur in ' groundwater underlying the site. The Bio-Trap samplers were retrieved on June 30,2009. Analysis of the results from the Bio-Trap samples is in progress. 7. On May 22, 2009, SGI submitted a Revised Well Installation Workplan to the Central Valley Regional ' Water Quality Control Board (CVRWQCB)for the installation of four additional groundwater monitoring wells(TSG-MW-1 17A/B/C/D)to be installed approximately 1,000 feet to the west-northwest of existing monitoring.well TSG-MW-115. The well installation was conditionally approved by the CVRWQCB in a letter to World Oil Corp. dated June 12, 2009. World Oil Corp. issued a letter to the property owner on ' June 24, 2009 requesting permission to access the property in question for the purpose of installing the well cluster. No response was received to the initial request, therefore, a second letter dated July 29, 2009 was sent to the property owner. In August of 2009, World received a telephone call from the ' property owner, in which the property owner verbally denied access to their property. On October 15, ' 1 The Source Croup,Inc. 1 ' World sent a letter to the CVRWQCB requesting assistance in accessing the property(APN 368-010-13), west of the PG&E facility. 8. On September 18th,2009,SGI submitted a workplan for the installation of four additional SVE wells to be ' installed within the former South Tank Farm/Refinery area. The workplan was approved by the CVRWQCB in a letter to World Oil Corp.on October 12,2009. During the period November le through November 23`t, 2009, four new SVE wells (TSG-SVE-118 through TSG-SVE-121) were installed to ' supplement existing SVE wells and to allow soil vapor extraction within newly exposed vadose zone at a depth from 120 feet to approximately 150 feet bgs. The new wells were additionally screened approximately 20 feet into groundwater to accommodate a potential further decrease in groundwater ' elevation. The wells can additionally be used as groundwater monitoring points to monitor groundwater conditions within the source area. The four new wells were tied into the HCVES between December 7 and December 11, 2009. ' WORK PROPOSED FOR NEXT PERIOD (January 2010 through May 2010): ' 1. Complete groundwater gauging, purging, and sampling in March 2010. 2. Continue operation and maintenance of the high capacity vapor extraction system (HCVES). Continue liquid-phase hydrocarbon(LPH)removal from affected on-site wells using a vacuum truck and/or stingers, t where necessary. 3. Continue to work with the CVRWQCB as well as the property owner to access the property west of the former PG&E Kern Power Plant for the purpose of installing additional groundwater monitoring wells for ' the purpose of down-gradient delineation.
