Vice President, Environmental Affairs World Oil Corporation 9302 South Garfield Ave. South Gate, CA 90280 -3896 REVIEW OF WELL INSTALLATION REPORT, FORMER SUNLAND OIL REFINERY, BAKERSFIELD, KERN COUNTY (a Arnold Schwarzenegger Governor We reviewed the report titled Well Installation Report, Former Sunland Oil Refinery, 2152 Coffee Road, Bakersfield, California (Report) dated 28 February 2007. The Report was prepared and submitted to our office on behalf of World Oil Corporation (World) by The Source Group, Incorporated (SGI) of Thousand Oaks, California. The Report documents field activities to install three well clusters; each with an A, B, and C casing; in general compliance with the workplan titled Well Installation Workplan and Water Well Survey Summary (Workplan) dated 13 July 2006. We approved the Workplan in a letter dated 6 September 2006 with the condition that in addition to the analysis for MTBE, the initial few rounds of sampling from the proposed new wells include chemical analysis for other fuel oxygenates including methanol, ethanol, tertiary butyl alcohol (TBA), di- isopropyl ether (DIPE), ethyl tertiary butyl ether (ETBE), and tertiary amyl methyl ether, (TAME). In a 20 November 2006 letter, SGI requested an extension until 28 February 2007 to submit the well installation report, which was. granted in the Regional Water Board letter dated 28 November 2006. The enclosed memorandum contains a detailed summary and technical review of the Report' by Regional Water Board staff. After reviewing the Report, we have the following comments: Inconsistencies were found in well installation information provided in the approved Workplan, the Application and Permit for Monitoring Wells submitted to the Kern County Environmental Health Services Department (Kern County Well Permits), and the specifics of the well construction as documented in the Report. These inconsistencies include the schedule. of the PVC well casings installed, the diameter of the well casings, the number of borings into which the casings were installed, and the diameter of these borings. World needs to submit information clarifying-the-above inconsistencies. 2. The Report did not indicate that the B- and C -Zone well casings were installed with centering guides (centralizers) as required by California State Well Standards to ensure California Environmental Protection Agency 0a Recycled Paper Mr. John P. Hundley - 2 - 22 July 2008 the casing(s) remain in the center of the boring to ensure even thickness of annular seal and /or gravel pack during placement. World needs to clarify if the B- and C -Zone casings are equipped with centralizers or what other measures were taken to ensure the casings remained centered in the borehole during well construction. 3. The boring log for TSG- MW -116A directs the reader to see the boring log for well TSG - MW -115 B/C for lithologic descriptions. Weil TSG -MW -115 B/C is located approximately 630 feet away from well TSG- MW -116A. The reference to well TSG - MWA 15 B/C for lithologic descriptions appears to be an error. World needs to confirm if this is a typographical error and amend the appropriate page of the boring log for TSG- MW -116A and resubmit it to this office. 4. The text of the Report indicates that borings drilled with the Sonic rig produced a continuous core of soil material for logging lithology. The boring log for TSG -MW -116 B/C does not indicate that the boring was logged by continuous core as, is indicated in the boring logs for wells TSG -MW -114 B/C and 115 B /C. World needs to confirm that the boring for well TSG -MW -116 B/C was logged by continuous core. Additional detail is provided in the enclosed Regional Water Board staff review memorandum.

Carlson SIGNATURE: 0 Arnold Schwarzenegger Governor Engineering Geologist PG No. 5379, CEG No. 1695, CHg No. 488 SUBJECT: REVIEW OF WELL INSTALLATION REPORT, FORMER SUNLAND OIL REFINERY, BAKERSFIELD, KERN COUNTY reviewed the report titled Well Installation Report, Former Sunland Oil Refinery; 2152 Coffee Road Bakersfield, California (Report) dated 28 February 2007 and received by our office on 2 March 2007. The Source Group, Inc. (SGI) of Thousand Oaks, California, prepared the Report and submitted it to this office on behalf of World Oil Corp. (World). Three well clusters (each cluster comprised of an A, B, and C casing) were installed west and northwest of the former refinery site. One cluster was installed west of the refinery in an area historically used for agricultural purposes. The two remaining well clusters were installed on the former PG &E Kern Power Plant property, near the western property boundary. Figures 1 and 2 from the Report are attached for reference. Background In a 20 March 2006 review letter, our office requested submittal of a workplan for the installation of additional monitoring wells west of the source area at the former Sunland Refinery. This request was based upon our previous analysis of site groundwater quality data and trends. Our analysis suggested the methyl tertiary-butyl ether (MTBE) had migrated over 2,600 feet downgradient of the source area, and continued to migrate at concentrations exceeding applicable drinking water standards. There were no groundwater monitoring wells in that area at that time. In response to our request, SGI, on behalf of World, submitted a workplan for the installation of additional groundwater monitoring wells dated 13 July 2006 and received by our office on 17 July 2006. The proposed scope of work included the installation of three monitoring well clusters, each screened at three depth intervals, approximately 2,500 feet west of the source area. Two of the well clusters would be installed north of the Atchison, Topeka and Santa Fe railroad tracks on the western boundary of the PG &E Kern Power. Plant property. The-third well cluster would be installed on the Sunland Oil property south of the railroad tracks. The wells would be added to the next and subsequent semi - annual groundwater sampling events and reported in the semi - annual groundwater monitoring and sampling reports. California Environmental Protection Agency 0 Recycled Paper Sunland Well Installation Report - 2 - 22 July 2008 In our letter dated 6 September 2006, the workplan was approved with addition of the following: 1. In addition to analysis for MTBE, the initial few rounds of sampling from the proposed new wells should include chemical analysis for other fuel oxygenates including Methanol, Ethanol, Tertiary Butyl Alcohol (TBA), Di- Isopropyl Ether (DIPE), Ethyl Tertiary Butyl Ether (ETBE), and Tertiary Amyl Methyl Ether (TAME). Well Installation The three well clusters, designated TSG- MW- 1 14A/B/C through TSG- MW- 1 16A/B/C were installed from 15 January to 21 January 2007. In order to provide additional vertical and lateral delineation of the western (downgradient) edge of the contamination plume, the wells were installed at the following depth intervals: A -Zone - approximately 80 to 130 feet below ground surface (bgs), B -Zone - approximately 165 to 175 feet bgs, and the C -Zone - approximately 200 to 210 feet bgs. Each A -Zone well was completed in an individual 8 -inch OD hollow stem auger borehole. The B- and C -Zone wells were installed in the same borehole drilled /installed using a Sonic drilling rig equipped with 8 -inch OD casing. The Sonic drilling method allows collection of a continuous core, which was lithologically logged, using the Unified Soil Classification System, and monitored for volatile organic vapors using a hand held. photoionization detector. Samples were collected from the core every five feet for possible laboratory analysis. Five samples, at 20 -foot intervals, were submitted for analysis from borings TSG -MW -114 and —115 and four samples from TSG -MW -116. Soil samples were analyzed for total petroleum hydrocarbons as gasoline (TPHg); benzene, toluene, ethylbenzene, total xylenes (collective known as BTEX); and MTBE by EPA Method 8260, and for TPH- carbon chain distribution (TPHcc) by EPA Method 8015M. The Report text indicates that all monitoring wells were constructed of 2 -inch diameter Schedule 40 PVC casings and 0.020 -inch slotted screens. Each well was screened in approximately the intervals described above. The filter pack is comprised of No. 2/12 sand. Each sand pack interval was sealed with hydrated bentonite chips /pellets as a transition seal followed by bentonite grout to near ground surface. Each of the six borings was completed at the surface with a steel monument set in concrete. All groundwater monitoring wells were developed using a development rig on 24 January 2007. Each well was surged with a rubber surge block and purged using a submersible pump of no less than three well volumes of groundwater. Soil observed from the core consisted primarily of poorly - graded sand and silty sand, with lesser amounts of silt with sand and silt interbeds..Groundwater was encountered during drilling at approximately 105 feet bgs. The wells were surveyed on 22 February 2007 by a Professional Licensed Land Surveyor for compliance with GeoTracker submittal requirements. The Report states -that the survey data will be included with the next semi - annual groundwater monitoring and sampling report. Petroleum hydrocarbon constituents were not detected above laboratory method reporting limits in any of the soil samples submitted for analysis. The wells were sampled as part of the Sunland Well Installation Report - 3 - 22 July 2008 next semi - annual sampling event at the site. Results of the first and subsequent groundwater sampling events were reported in their respective semi - annual groundwater monitoring and status reports. I will provide comments to results of the groundwater sampling in our comments to each respective groundwater monitoring report. Comments The Report states, "The installation of the G wells was performed in accordance with SGI's Well Installation Workplan and Water Well Survey Summary, dated July 13, 2006 ". However, our review found several inconsistencies between the Workplan and the Report as follows: Inconsistencies were found in well installation information provided in the approved Workplan, the Application and Permit for Monitoring Wells submitted to the Kern County Environmental Health Services Department (Kern County Well Permits), and the specifics of the well construction as documented in the Report. These inconsistencies include the schedule of the PVC well casings, the diameter of the well casings, the number of borings into which the casings were installed, and the diameter of these borings. Schedule of PVC Well Casing Installed - The approved workplan states, "All monitoring wells will be constructed of either two -inch diameter (shallow and middle zones) or four -inch diameter (deep zone) Schedule 40 PVC casings and 0.020 -inch slotted screens ". The 6 September 2006 Regional Water Board letter approving the workplan stated our understanding of the proposed work, "The upper well casings] and screens will be constructed of 2 -inch diameter Schedule 40 PVC; the deeper zone casing of 4 -inch diameter PVC'. The Kern County Well Permits, contained within Appendix B of the Report, agrees with the casing diameters proposed for each zone but indicates that all casings will be Schedule 80 PVC, not Schedule 40 as stated in the approved Workplan. The Report text states on Page 3, "All monitoring wells were constructed of two -inch diameter. Schedule 40 PVC casings and 0.020 -inch slotted screens ". However, the Boring/Well Construction Logs contained within Appendix C of the Report indicate that TSG -MW -114 B/C and TSG -MW -116 B/C are constructed with two - inch diameter Schedule 80 PVC well casing and that all A -Zone wells and TSG - MW -115 BIC were installed with two -inch diameter Schedule 40 PVC well casing. World needs to clarify what schedule(s) of PVC well casing were installed in these wells and, if different than what was approved in the Workplan and the Kern County Well Permits, provide an explanation as to why construction deviated from the approved specifications. 2. Well Casing Diameter - As stated in No. 1 above and addressed in both the approved workplan and the approved Kern County Well Permits, the proposed well casing diameters were two -inch in the A- and B -Zone wells and four -inch in the C -Zone wells. However, the Report indicates that two -inch diameter casing was used for all wells. World needs to provide an explanation as to why construction of the C -Zone wells deviated from the approved workplan and the approved Kern County Well Permits. Sunland Well Installation Report - 4 - 22 July 2008 3. Number of Borings / Dual Completion Wells — The approved workplan states, "World is proposing to install a total of three (3) new off -site groundwater monitoring well clusters west of the former Sunland Refinery". It further states, "World will install groundwater well clusters (three individual well casings) at each of the three proposed locations allowing assessment of discrete groundwater depth intervals at each proposed monitoring location ". The Report also states, "Wells will either be drilled using a hollow stem auger drill rig, sonic drill rig, or mud rotary drilling rig ". No mention is made about installing dual completion wells, i.e., two casings within the same borehole. The Kern County Well Permits, contained within Appendix B of the Report, indicates. the A -Zone wells will be drilled using hollow stem auger drilling an 8 -inch diameter boring. The approved Kern County Well Permits for the B -Zone and C -Zone wells indicates that the wells will be drilled using Sonic drilling methods and that the borehole diameters for the B -Zone and C -Zone wells will be 7 inches and 8 inches, respectively. This clearly indicates that the B -Zone and C -Zone wells will be installed within separate boreholes. However, the Report states, "The A -Zone casings are installed in separate boreholes from the BIC -Zone casings ", and further states, "All six well nests (three single and three dual) were completed at the surface with steel monument casings set in concrete." These statements, as well as the boring /well construction logs in Appendix C of the Report, clearly indicate that the B -and C -Zone casings at each well cluster are installed in the same borehole as dual completion wells. The dual completion wells do not conform to the well construction specifications in the approved workplan or the approved Kern County Well Permits. A review of the project file did not reveal any record of subsequent communication with this office proposing or approving such changes. Therefore, World did not install the wells in accordance with the approved well installation workplan or the approved Kern County Well Permits. In addition, this modification to the approved workplan also brings into question issues regarding State Well Construction Standards, which are discussed below. 4. Boring Diameters — The approved workplan states, "Wells will either be drilled using a hollow stem auger drill rig, sonic drill rig, or mud rotary drilling rig". The diameter of each boring is not specified. The Kern County Well Permits indicate that the diameter of each boring for the A -Zone wells will be 8 inches, 7 inches for the B -Zone wells, and 8 inches for the C -Zone wells. The Report indicates that borings for the A -Zone wells are 8 inches in diameter, in accordance with the well permits. .Borings for the B/C -Zone dual completion wells are stated to be drilled "...using a Sonic drilling rig equipped with 8 -inch OD casing". Information in the Report indicates that the B/C -Zone dual completion wells are installed in 8 -inch diameter boreholes and that the well casings are both two -inch PVC. Manufacturing specifications for PVC well casing- indicates that -two -inch Schedule 40 and Schedule 80 PVC well casing both have an OD of 2.375 inches. Therefore, regardless of whether the casings installed are either Schedule 40 or Schedule 80, the two casings together have a combined outside dimension of 4.750 inches. When installed in an 8 -inch diameter boring, the two Sunland Well Installation Report -5.- 22 July 2008 casings leave only 3.25 inches remaining or approximately 1.6 inches of annular space; which is less than the minimum 2 inches required by California State Well Standards (Bulletin 74 -81 and 74 -90) to ensure adequate filter pack thickness and annular seal. • The Report did not indicate that the B- and C -Zone well casings were installed with centering guides (centralizers) as required by California State Well Standards to ensure the casing(s) remain in the center of the boring to ensure even thickness of annular seal and /or gravel pack during placement. World needs to specify if the B- and C -Zone casings were equipped with centering guides. The boring log for TSG- MW -116A directs the reader to see the boring log for well TSG - MW -115 B/C for lithologic descriptions. Well TSG -MW -115 B/C is located approximately 630 feet away from well TSG- MW -116A. The reference to well TSG - MW -115 B/C for lithologic descriptions appears to be a typographical error. World needs to confirm if this is a typographical error and amend the appropriate page of the boring log for TSG- MW -116A and resubmit it to this office. The text of the Report indicates that borings drilled with the Sonic rig produces a continuous core of soil material for logging lithology. The boring log for TSG -MW -116 B/C does not indicate that the boring was logged by continuous core as is indicated in the boring logs for wells TSG -MW -114 B/C and 115 B /C. World needs to confirm that the boring for well TSG -MW -116 B/C was logged by continuous core and if so amend the appropriate page of the boring log for TSG -MW -116 B/C and resubmit it to this office. The text of the Report states, "Each well was surged with a rubber surge block and purged using a submersible pump of no less that three well volumes of groundwater". World should note that in describing the well development the reference to pumping of no less that three well volumes of groundwater should not be used as a criterion for determining if development is complete. Surging and pumping a well for development should continue until the discharge water is visibly clear and the purge parameters are stable. Future well installation reports should include a well development log for each well documenting in detail the steps and progress of well development including but not necessarily limited to time, gallons pumped, visual description of the discharge water, purge parameters values during pumping, etc. Attachments DLC:dlc R:lcleanuplCleanuplProjects\DLC Projects\Sunland Refinery (former)1Sunland Well Install Review Memo 072108.doc I 1 I I I "O TSC 1kI- 114B /C 15G- 114A 1 I I 1 -O 8 196- w- 1158/C Esc-�r -115 1 Rmeciale Hqi+vay58 - .__._.. 1 - - - - - - - - SE- W -291 u , - 1SG- MW- 1168 /C IW -116J1 SE -YE/ I MW -14+ ` SE -WW -26 I SE -1 - 16(R)i 1 I I I I I 1 I I I I I I I I SE-MW-21+ v f iS l' --r CIZ I >, t OftEMALdhis o?­,740a and Santa Fe Radroad - /D TSC-W -113c NN-5+ YW-4 4W -16 F b•:.a ow 24 t NW-15 i IA9-i19i�- SE -2$ -�- Iflll -12 o I• i 0 ,y' L `V SE- WW -22+ o ii ii 1t =I t� WW -10(R )4 t f t; ?i V1i i� 3 't I I - SE -mw- J I` General Site Legend: — - - Sunland Property Boundary -- -- - Center Line of Coffee Road 6 Ft.

(World) dated August 25, 2008, pertaining to review of the following reports: • First Half 2006 Semi - Annual Groundwater Monitoring and Status Report dated 1 June 2006, • Second Half 2006 Semi - Annual Groundwater Monitoring and Status Report dated 1 January 2007, • First Half 2006 Semi - Annual Remediation Progress Report dated 1 June 2006, • Second Half 2006 Semi - Annual Remediation Progress Report dated 1 January 2007, • Annual Remediation Summary Report (2006) dated 28 March 2007, • First Half 2007 Semi - Annual Groundwater Monitoring and Status Report dated 1 June 2007, • Second Half 2007 Semi - Annual Groundwater Monitoring and Status Report dated 21 December 2007, • First Half 2007 Semi - Annual Remediation Progress Report dated 1 June 2007, • Second Half 2007 Semi - Annual Remediation Progress Report dated 28 December 2007, • Annual Remediation Summary Report (2007) dated 13 March 2008. In their letter, the RWQCB directed World to "prepare an Addendum Report addressing specific comments (open bullets) to reports reviewed..." in an RWQCB staff memorandum that was attached to the referenced letter. The "open bullet" comments from the staff memorandum are listed below along with World's responses to those comments. A number of comments request corrections or additions to specific reports. In response to those requests, corrections were made to the reports specified. SGI has identified a input error within the "Cumulative TPH Removed" column of Table 3 of the Second Half 2006 Semi - Annual Remediation Progress Report. While this error was small, the error was propagated through subsequent Remediation Progress Reports. As such, SGI has provided slip sheets for affected 2006 and 2007 Remediation Progress Reports, and has included the slip sheets within the attachments to this submittal, In the case of the Second Half 2007 Semi - Annual Remediation Progress Report, a revised copy of the entire report is included herein. The RWQCB should insert correction sheets where applicable and should replace the hard copy of the Second Half 2007 Semi - Annual Remediation Progress Report with the revised copy. PDF copies of the revised reports will also be uploaded to the GeoTracker database. 299 West Hillcrest Drive Telephone: (805) 373 -9063 Suite 220 Facsimile: (805) 373 -9073 Thousand Oaks, California 91360 e -mail: mlabrenz @thesourcegroup.net Response to RWQCB Letter Dated August 25, 2008 November 10, 2008 Former Sunland Refinery Page 2 Bakersfield, CA Second Half 2006 Remediation Progress Report 1) The lanauaae of the text suaaests that the HCVES was back online on 4 October 2006. However, Figure 5 of the Report, that includes a graphical display indicating when the HCVES is operational, suggests it was not back fully operational until about three weeks after the start-up testing. World needs to amend the Report text and /or Figure 5 to clarify when the HCVES was again fully operational. SGI performed start -up testing of the HCVES system in catalytic mode on October 4, 2006, as described within the text of the report. This testing is reflected in graphical format on Figure 5 by a single line depicting operation (testing) of the system on October 4. Following the October 4 start- up testing, the system was manually shut down pending test evaluation. Upon receipt of test results, the system began full operation in catalytic mode on October 23, 2006: The start-up date of October 23 is supported by Figure 5 as well as included within the field notes. Text within the Second Half 2006 Remediation Progress Report has been amended to better clarify the chronology of system startup. The amended text is included herein as Attachment A. 2) Based upon data in the Report. the total down time for the HCVES for the conversion appears to be almost three months (31 July through or near the end of October 2006). This appears to be an inordinate amount of time for the HCVES to be non - operational to affect such a conversion. World needs to provide an explanation as to why the HCVES was non- operational for this length of time. Prolonged downtime was necessary to conduct required repairs to the Baker Furnace oxidizer. During the change over from thermal mode to catalytic mode, a system design flaw /manufacturing error was discovered, which did not permit rapid change over of the system from thermal mode to catalytic mode. The system was designed with two exhaust stacks so that the heat exchanger could be protected from the excessive heat generated during thermal oxidation. A large damper valve directs flow to one of the two exhaust stacks (catalytic stack or thermal stack) that process /discharge the vapors. However, during change over to catalytic mode, it was discovered that the large damper valve which directs flow to either the catalytic stack or thermal stack underwent metal fatigue and warping that in turn caused a failure of the valve stem bearings. As the damper valve assembly was inoperable and of poor design, it was necessary to remove the entire damper valve assembly from the unit. The system was redesigned to allow discharge only through the catalytic stack. System retrofit activities required confined space entry into the system, and welders that were 40 -hour trained in order to complete the necessary repairs. Engineering redesign and retrofit activities required prolonged system downtime. The Source Group, Inc.

Second Half 2007 Semi - Annual Groundwater Monitoring and Status Report 4) World did not present the results of all groundwater analyses in tables within the Report. During this sampling event groundwater samples were collected from select wells and analyzed for arsenic, total chromium, and hexavalent chromium -(chromium V0. However, the results of these analyses were not presented in data tables within the Report. World needs to ensure that future reports present current and historic results of all laboratory analyses of groundwater samples for arsenic, total chromium, and hexavalent chromium in a table(s) within each report, as are the results for other analyses. Arsenic, total chromium, and hexavalent chromium historical groundwater analytical results for former Sunland Refinery groundwater monitoring wells will be tabulated and included within future semi - annual groundwater monitoring reports. 5) World failed to incorporate analyses for oxygenates during this sampling event which were required in the Regional Water Board letter titled Well Installation Work Plan Review dated 6 September 2006. In addition to oxygenates, the samples should also be analyzed for 1,2 dichloroethane via USEPA Method 8260B and the results reported for all constituents for the next two monitoring events.

Response to RWQCB Letter Dated August 25, 2008 November 10, 2008 Former Sunland Refinery Page 4 Bakersfield, CA Second Half 2007 Remediation Proaress Report 6) The Report states that the HCVES operated, in the flare mode, approximately 2,523 hours during the reporting period (49 percent of the time). World needs to provide an explanation as to why the HCVES operated so little during this reporting period. Downtime, which occurred within the first month (May 2007) of the reporting period, is a function of the change over from catalytic oxidizer to the candle flare. Details of the change over are summarized further in the response to question 8 below. Throughout the second half 2007 semi - annual reporting period, the HCVES system was cycled on and off in an attempt to increase influent concentrations to the system and optimize mass removal vs. operating costs following a period of increasing well submergence. Groundwater elevations across the site had been steadily rising from approximately March 2005 through the first half of 2007. Groundwater elevations rose between 30 and 40 feet over the area of the former Sunland Refinery site. Rising groundwater levels considerably reduced the lower vadose zone available for soil vapor extraction. With much of the target zone submerged, influent concentrations to the HCVES decreased substantially. Cycling was an attempt to increase the concentrations into the system; however, such cycling decreased the overall system operational time. Significant increases in influent concentrations were not achieved during the cycling and thus system cycling was discontinued at the end of October 2007. 7) Approximately 1,181 gallons of LPH was collected by the HCVES and an additional 157 gallons of LPH manually bailed or vacuumed from affected wells by a vacuum truck. In total, 1,338 gallons of LPH were removed from the site during the reporting period. The Report states that as of this reporting period the total amount of LPH removed since December 1996 is approximately 15,009 gallons. However, my calculations for LPH removal since the previous monitoring report are as follows: First Half 2007 LPH Project Total 13,749 gallons Second Half 2007 Period Total 1,338 gallons New LPH Proiect Total 15,087 gallons World needs to recheck the LPH calculations and amend the text and Table 1 of the Report as necessary. The 1,338 gallons of LPH reported within the Second Half 2007 report was in error. The accumulated LPH value for Second Half 2007 should have been reported as 630 gallons (estimate 5 percent of total liquid removed from the site by vacuum truck). Therefore, the LPH accumulated total has been recalculated as 14,379 gallons. SGI has corrected the references (Page 2 of text and Table 1) in the enclosed Second Half 2007 Remediation Progress Report (Attachment D) as well as the reference within the Annual Remediation Summary Report (2007) included as Attachment E. The Source Croup, Inc. Response to RWQCB Letter Dated August 25, 2008 November 10, 2008 Former Sunland Refinery Page 5 Bakersfield, CA 8) Data within the Report indicates that the entire HCVES was off from 12 April 2007 through June 6 2007, almost 2 months. World needs to provide and explanation of why the HCVES was off during this period. Prolonged downtime was the result of a system malfunction that required engineering analysis / repairs to address system safety and operational concerns. On April 13, 2007, during a system restart, the system experienced a rapid temperature rise. Excessive thermal vapor expansion caused damage to the catalytic cell shelf as well as the catalytic access door, and the system was shut down. The rapid rise in temperature was experienced during startup of the system and raised questions as to the reliability of the Baker System control logic and system design. Both SGI as well as a third party engineering group conducted an evaluation of the system safety controls and design. Upon evaluation, it was determined that remediation activities should continue utilizing the John Zinc Flare, as further study was required to fully understand the cause of the oxidizer upset. The time required to complete the change from the catalytic oxidizer to the flare reflects the engineering analysis that was conducted and the importance of assuring safe operation of the HCVES. The system has subsequently undergone a major retrofit, including replacement of the two existing knock out tanks with upgraded tanks, repositioning of the automated dilution valves, incorporation of LEL fail -safe sensors at each blower inlet, and replacement of the Eclipse Veri- Flame flame monitoring controller (which at the time had been involved in a recall due to units allowing continuous gas flow to the burn chamber in the absence of a flame). 9) In Table 2g, the AS System Process Summary lists the "Air Sparge Flow Rate Per Well" as 39,217 scfm, which appears to be incorrect. World needs to check and amend as necessary. The Air Sparge Flow Rate Per Well within Table 2g should have read 5 — 15 scfm. Table 2g has been amended in the enclosed Revised Second Half 2007 Remediation Progress Report (Attachment D). 10) In Table 3 of the Report, the column "Notes" shows no entries, which is in contrast to previous reports. World needs to explain why no "Notes" are included in Table 3 of the Report. If this is in error, World needs to incorporate the necessary information and submit an amended Table 3 to this office. Notes providing detail on system operational parameters were inadvertently omitted from Table 3. The table has been revised to include entries within the "Notes" column. A corrected Table 3 is included within the enclosed Revised Second Half 2007 Remediation Progress Report (Attachment D). The Source Group, Inc. Response to RWQCB Letter Dated August 25, 2008 Former Sunland Refinery Bakersfield, CA November 10, 2008 Page 6 11) Figure 5 in the Report depicts periods when the HCVES, the South Tank Farm (STF) air sparging system (AS), and the WTF AS systems are "On" or "Oft'. Data in Figure 5 for the system status does not agree with system operational status as recorded in the High Capacity Soil Vapor Extraction /Air Sparge Monitoring Logs contained in Attachment D "O &M Field Logs" or with specific system status shown in Table 3. World needs to check, amend portions of the Report as necessary, and resubmit the amended portions of the Report to this office. The data has been rechecked and the figure revised. An amended Figure 5 and an amended Table 3 have been included within the enclosed Revised Second Half 2007 Remediation Progress Report (Attachment D). 12) Figure 5 in the Report indicates that the air sparging system in the West Tank Farm (WTF) has operated very little since mid- January 2007. World needs to provide an explanation as to why it was operated so little. Groundwater elevation across the former Sunland Refinery site increased consistently from March 2005 through April 2007. Groundwater elevation rose approximately 40 feet in the vicinity of the former West Tank Farm and former Refinery/South Tank Farm. The rise in groundwater elevation across the site created conditions in which greater volumes of water were being entrained into the SVE conveyance system, an issue that was particularly acute within the West Tank Farm. Troubleshooting of the system revealed that "short circuiting" of air /water from sparge wells installed at the Pan Pacific Facility (former West Tank Farm) into SVE wells (which are generally screened deeper than SVE wells at the Refinery/South Tank Farm) was responsible for a majority of the water being entrained within the SVE system. Excess water generated in early 2007 accumulated within the SVE trunk line connecting the West Tank Farm to the main remediation compound located within the former Refinery/South Tank Farm area, Water accumulation within the trunk line restricted vapor flow through the line, limiting SVE effectiveness. As the majority of hydrocarbon mass removal is attributed to SVE, air sparging was reduced at the West Tank Farm in order to continue effective SVE operation within this area. The West Tank Farm air sparge system was therefore operated very little during 2007 in order to alleviate the production and accumulation of water within the SVE West Tank Farm conveyance system, as the system was not designed to handle the quantity of water which was being produced. Groundwater began to decline in elevation beginning in the second half 2007 reporting period. The air sparge system at the former West Tank Farm has been operated continuously since early November 2007 when operation became more feasible, and water production declined. 13) There appears to be a possible contradiction in Attachment D, O &M Field Logs for 15 August 2007 and 23 August 2007. The former field log fails to indicate the HCVES departure status for Blower 2 and the arrival and departure status for the WTF AS system. In addition, this field log indicates in the notes/activities section that the system shut down due to a High /High condition in the AST faboveground storage tankl. However, the HCVES system arrival and departure status indicates "On" for both. The next system check field log for 23 August 2007 indicates that the HCVES was "Off" upon arrival and in the notes /activities section it indicates that the AST was emptied. It appears that the The Source Group, Inc. Response to RWQCB Letter Dated August 25, 2008 November 10, 2008 Former Sunland Refinery Page 7 Bakersfield, CA system shut down note may belong on the 23 August 2007 field log. World needs to clarify and review. Blower 2 did not operate during the entire reporting period. Future field sheets will be completed so that blower status is clearly discernable. The WTF AS system was off from May 1 through November 1, 2007, with the exception of one period (Sept 5 through Sept 11). The field sheet should reflect system "off' on arrival and departure throughout this time period, with the exception of the period outlined above. Future field sheets will be completed so that AS system status is clearly discernible. The STF status on departure for August 15, 2007 should be noted as "Off," not "On" (hour meter, electric meter, and the gas meter all had identical readings from 8/15 to 8/23). The above ground storage tank high leveled on August 15 during line purging and subsequently shut the system down during the period that the technician was onsite. Due to a full AST, the technician could not restart the system that day. On August 23, 2007, a vacuum truck removed fluids from the AST and the system was restarted. 14) Similar to the issue discussed in the previous comment. the 30 Auaust 2007 HCVES / AS Monitoring Log does not indicate HCVES Blower 2 departure status, AS STF departure status, nor the AS WTF arrival and departure status. World needs to ensure that the HCVES /AS Monitorina Loas are property completed in the field by personnel monitorina the system. SGI will continue to work with the on -site technicians to supply complete and accurate log sheets, and make every effort to immediately catch /correct any errors /omissions. 15) Field Memoranda, provided in Attachment D of previous reports, are not included in the current Report. World needs to include all Field Memoranda in Attachment D of all future Remediation Progress Reports. SGI has discontinued the use of Field Memoranda and has instructed the field technician to complete all field notes within the "Notes" section of the field O &M log. In this manner, all information pertaining to the O &M visit is included on one field sheet. 16) Information in the Report indicates that the catalytic oxidizer was taken off-line and the flare system brought back on line. World needs to provide an explanation as to why. As discussed in the response to RWQCB question Number 8, the Baker Furnace experienced a system malfunction that required engineering analysis /repairs to address system safety and operational concerns. On April 13, 2007, the system experienced a rapid rise in temperature. Excessive thermal vapor expansion caused damage to the catalytic cell shelf as well as the catalytic access door. In lieu of complete cessation of soil vapor extraction, the John Zinc flare was brought on -line on May 21, 2007 to continue vapor extraction operation during the period that engineering evaluation and system repair were being conducted on the Baker oxidizer. The Source Group, Inc. Response to RWQCB Letter Dated August 25, 2008 November 10, 2008 Former Sunland Refinery Page 8 Bakersfield, CA The HCVES has subsequently undergone a major retrofit, including the replacement of the two existing knock out tanks with upgraded tanks, repositioning of the automated dilution valves, incorporation of LEL fail -safe sensors at each blower inlet, and replacement of the Eclipse Veri- Flame flame monitoring controller (which at the time had been involved in a recall due to units allowing continuous gas flow to the burn chamber in the absence of a flame). The Baker Furnace oxidizer was brought back online (thermal mode) as the primary abatement device on August 14, 2008 following the retrofit activities described above. J In the Summary of Individual Well Concentrations, Vacuums, and Depths to Product/Water tables, contained in Attachment B of the Report, some of the Product Thickness values are not reported even though data of the Depth to Water and Depth to Product are present in the table. Examples in the 6 June 2007 measurements include wells AS -81b and SE- MW -9(R); well MW -5 in the 15 August 2007 measurements. Similarly, there were several other wells in the Summary tables for other dates also lacking this information. World needs to update the Attachment B tables as necessary and resubmit them to this office. The summary. tables presenting individual well concentrations, vacuums, and depths to product/water have been reviewed and revised. Corrected summary tables (June 6, 2007, August 15, 2007, and October 10, 2007) have been included within Appendix B of the enclosed Revised Second Half 2007 Remediation Progress Report (Attachment D). 18) World needs to provide an explanation as to why concentrations or vacuum data for the vapor extraction wells (TSG -VE -90 through TGS- VE -96), located on the PG &E property, are not included in the tables contained in Attachment B of the Report. Individual well concentrations are collected in order to optimize the HCVES, with the general objective of maximizing influent hydrocarbon concentrations to the system to the extent possible. Therefore, optimization entails the adjustment of individual well casing valves to optimize flow rates and influent concentrations. Wells TSG -VE -90 through TSG -VE -96 are located north of the Atchison Topeka and Santa Fe Railroad tracks on property owned and operated by Pacific Gas and Electric (PG &E). The above referenced soil vapor extraction wells were installed concurrently with air sparge wells operating with the objective to strip dissolved phase volatile hydrocarbons from groundwater immediately downgradient of the former Refinery / South Tank Farm. The purpose of vapor extraction wells TSG -VE -90 through TSG -VE -96 is to mitigate potential fugitive emissions related to sparging within this area. As such, wells TSG -VE -90 through TSG -VE -96 are always open or partially open to the SVE system. SGI does not regularly include the wells in question within the monthly or bi- monthly optimization, as their status does not change relative to influent concentrations. SGI does monitor these wells periodically. As these wells are positioned a significant distance from the source area and primarily for air sparge recovery/emissions control, individual well vapor concentrations within the above referenced wells have historically registered less than 100 ppmv. The Source Group, Inc. Response to RWQCB Letter Dated August 25, 2008 November 10, 2008 Former Sunland Refinery Page 9 Bakersfield, CA J In wells with liquid petroleum hydrocarbons but comparatively low measured hydrocarbon vapor concentrations, World needs to sample the liquid product and analyze the samples for carbon chain C -6 through C -44 to identify the hydrocarbon product and determine if this product is amenable to remediation by the HCVES. The product may be composed of less volatile hydrocarbons such as kerosene or diesel and not respond well to the HCVES. World will conduct speciation of liquid petroleum hydrocarbons in the future to determine the types of product which occur within the subsurface. 2007 Annual Remediation Summary Report 20) The reported 30 tons of hydrocarbons removed in 2007 is significantly less, only 35 %, of the estimated 86 tons reported removed in 2006. The amounts of both LPH and MTBE recovered / destroyed in 2007 are also significantly less with both being about 60 %; 2,832 gallons and 0.5 tons; respectively; of that reported for 2006. World needs to provide a discussion regarding the significant decline in the amounts of these constituents removed in 2007 as compared to 2006. The reduction in hydrocarbon mass removal in 2007 relative to 2006 is attributed to two site conditions. The primary contributing factor affecting the relative reduction in hydrocarbon mass removal in 2007 was the rise in groundwater levels across the site which subsequently reduced the vadose zone area available for SVE. A secondary contributing factor was related to the lower HCVES uptime in 2007 relative to 2006. Groundwater elevations across the site (including the source area underlying the former Refinery / South Tank Farm and West Tank Farm) continued to rise into early 2007, effectively reducing the vadose zone available for soil vapor extraction. Volatile hydrocarbons captured within the unsaturated vadose zone by the HCVES account for a majority of hydrocarbon mass removal at the site. Hydrocarbon mass within the upper vadose zone (surface to 40 feet bgs) and intermediate vadose zone (40 to 80 feet bgs) underlying the site has been significantly reduced by the operation of the HCVES. Significant remaining hydrocarbon mass continues to reside within the lower vadose zone (90 to 120 feet bgs). However, over the last two years, rising groundwater elevations have saturated the lower vadose zone, limiting SVE at these deeper depths. In 2007, SVE continued to be employed across the site; however, lower influent concentrations were experienced due to the restricted vadose zone available to SVE. The HCVES up time was not as great in 2007 as compared to 2006 (5061 hours vs. 5710 hours). As discussed in previous responses, reduced HCVES uptime was a function of system shutdown and subsequent required engineering analysis as well as cycling of the HCVES in an attempt to increase influent hydrocarbon concentrations to the system. The Source Group, Inc. Response to RWQCB Letter Dated August 25, 2008 November 10, 2008 Former Sunland Refinery Page 10 Bakersfield, CA 21) Under the heading Assessment Activities, the Report states that no additional assessment activities were performed in relation to the former Sunland refinery site during calendar year 2007. 1 believe that additional information should be included in this section of the Report. (section omitted). World should revise the Assessment Activities section of the Report to include a discussion of the installation of the three well clusters TSG -MW- 114A/B /C, - 115AIB /C and - 116A/B /C, the sampling of the wells during each of the two regularly scheduled semiannual sampling events in 2007, and the analytical results of those sampling events .... (section omitted). The results and conclusions should be discussed in the Report test due to the significance of the detection of MTBE and benzene in excess of drinking water standards in wells TSG -MW -115 B and C, respectively, of depths from approximately 160 to 210 feet and 2,900 feet west - northwest (downgradient) of the anticipated source area of the former Sunland refinery. The Annual Remediation Summary Report (2007) has been amended to include a discussion of the well installation activities which occurred in January 2007. Corrected text for the Annual Remediation Summary Report (2007) is included as Attachment E. 22) On page 3, paragraph 1, the Report states in pertinent part, "Vapor samples were collected from the inlet header(s) for laboratory analysis once per month" In my review of the two semi - annual remediation progress reports, there are no analytical results reported for influent vapor samples collected during the months of April and June 2007. The Process /Influent Concentrations (STF, WTF, PG &E combined) reported in Table A contained within Appendix A of the Report indicates, "System off - line" during April and June suggesting this is the reason samples were not collected these months. However, data in the respective semi - annual remediation progress reports indicated that the HCVES was operational from 1 April through 12 April and from 6 June through 30 June. Therefore, sufficient operational time existed each month during which samples could reasonably have been collected. World should modify the Report to be accurate and state when orocess/influent vapor samples were collected for analysis. The HCVES was shutdown by the technician on April 13, 2007, as a result of the system malfunction described in greater detail within response 8 and 16 above. At the time of shut down, the influent vapor sample for the month of April had not yet been collected. Following the system shut down, the system was not started through the end of the month due to safety concerns. Therefore, an influent vapor sample was not collected or analyzed for the month of April 2007. The HCVES was temporarily restarted in flare mode on May 21, 2007. Influent vapor samples were collected from the HCVES on May 21 as well as on June 20, 2007. However, the June 2007 laboratory report was inadvertently omitted from the Second Half 2007 Semi - Annual Remediation Progress Report. The laboratory report documenting the June 2007 influent laboratory data, as well as sections of the Second Half 2007 Remediation Progress Report which require amendment (Tables 1, 2b, and 3), are included within the enclosed Revised Second Half 2007 Remediation Progress Report (Attachment D). The Source Group, Inc. Response to RWQCB Letter Dated August 25, 2008 Former Sunland Refinery Bakersfield, CA November 10, 2008 Page 11 23) In addition, processlinfluent concentrations are reported in Table A of the Report and laboratory reports are found in Attachment A of the Second Half Semi - Annual Remediation Progress Report (2007) for samples collected on 21 May 2007 even though data from both 2007 semi- annual remediation progress reports indicates that the HCVES and air sparging systems were all off continuously from 13 April 2007 through 6 June 2007. World should explain how process /influent vapor samples were apparently collected 21 May 2007 even though the entire remediation system was off -line from 13 April 2007 through 6 June 2007. As described above, the system was temporarily restarted in flare mode on May 21, 2007, at which time a process influent sample was collected. Table 3 of the Second Half 2007 Semi - Annual Remediation Progress Report, which showed system startup on June 6, 2007, was incorrect. Table 3 of the Second Half 2007 Remediation Progress Report has been amended to reflect the system operational status during the flare startup period, and is included within the enclosed Revised Second Half 2007 Remediation Progress Report. Summary Comments 24) With the new hydrogeologic and groundwater data now available from the installation and sampling of new groundwater monitoring wells, World needs to prepare an updated interim evaluation monitoring report summarizing the geologic data and laboratory analytical data for analyses of soil and groundwater. This should include, but not be limited to, updated geologic cross - sections depicting geology, well construction details, analytical data on soil samples, and groundwater analytical results including isopleth maps depicting concentrations contours of all constituents of concern in each hydrostrati rg aphic unit identified. The report shall provide sufficient detail to be the basis for and should include proposals for additional investigative work to delineate the lateral and vertical extent of groundwater impacted by petroleum hydrocarbons. An Interim Evaluation Report will be submitted to the RWQCB in a separate submittal. 25) Based on the above, World needs to prepare a draft fact sheet on the investigative work completed to date and the findings. The draft fact sheet shall be submitted to this office for review and comment. World shall also provide a list of parcels, including Assessors Parcel Number (APNs), located within 500 feet of the site; the associated names and addresses of property owners andlor residents for each parcel, and any other interested parties or groups. For purposes of this requirement, "site" refers to all parcels with known contamination or which overlie known contamination that originated from the former Sunland refinery. Once the draft fact sheet is approved by this office, World will need to distribute the fact sheet to the property owners, residents, and other interested parties on the list described above. Please see Attachment F for the Draft Fact Sheet and Assessors Parcel Number / property owner information. The Source Group, Inc. Response to RWQCB Letter Dated August 25, 2008 Former Sunland Refinery Bakersfield, CA November 10, 2008 Page 12 26) The remediation system at the site has been in operation since March 1996 a period of approximately 12 years. Reports indicate that as of the end of 2007, the remediation efforts have removed a total of 3,856 tons of petroleum hydrocarbons and 20 tons of MTBE from the subsurface below the former Sunland refinery site. World should prepare a more extensive Remediation Progress Report that includes, but is not necessarily limited to, reporting changes in hydrocarbon product types and concentrations in soil and groundwater relative to the initiation of remediation efforts and over the last two years; the types and estimated amounts of hydrocarbon product(s) remaining in the subsurface including floating product on the water table; changes in the hydrocarbon vapor concentrations from individual wells and HCVES influent concentrations over time; graphical data presentations, such as isopleth concentration contours on plan view maps and cross sections, depicting the changes over time and current conditions; an evaluation of the impacts, both positive and /or negative, of fluctuations in the groundwater table elevation on remediation efforts: providing sufficient information, analysis and conclusions to support recommendations for changes, if any, or why no changes to the remediation efforts are warranted; and providing and updated estimate as to the time required under currently known conditions to complete remediation at the site. A more extensive Remediation Progress Report will be submitted to the RWQCB in a separate submittal.

An estimated 58,140 pounds of hydrocarbons were extracted and destroyed by the thermal oxidizer during this reporting period, bringing the cumulative total of hydrocarbons treated to 7,637,870 pounds since the inception of vapor extraction at the site on March 22, 1996. An estimated 12 pounds of MtBE were extracted and destroyed by the thermal oxidizer during the reporting period, bringing the cumulative total of MtBE treated to 39,170 pounds since October 1996, the earliest date data was available for MtBE. 299 West Hillcrest Drive Telephone: (805) 373 -9063 Suite 220 Facsimile: (805) 373 -9073 Thousand Oaks, California 91360 e -mail: mlabrenz @thesourcegroup.net Mr. Bruce Myers, CVRWQCB January 1, 2007 Second Half 2006 Remediation Progress Report Page 2 Approximately 11,800 gallons of liquid, including liquid phase hydrocarbons (LPH) and condensate generated during soil vapor extraction were removed from the site during the reporting period by Asbury Environmental Services and transported to Demenno Kerdoon in Compton, California for disposal /recycling. Approximately 1,180 gallons of LPH was collected by the HCVES (visually estimated at 10 percent of the liquid collected in the condensate knockout tanks) and a further 78 gallons of LPH manually bailed or vacuumed from affected wells by a vacuum truck. In total, 1,258 gallons of LPH were removed from the site during the reporting period and the total amount of LPH removed since December 1996 is approximately 11,934 gallons. During the reporting period, the HCVES was converted from thermal to catalytic mode of operation. The HCVES and AS systems were manually shutdown on July 31, 2006. The catalyst was installed in September 2006 and start-up testing was performed on October 4, 2006 under the supervision of San Joaquin Valley Air Pollution Control District (Mr. John Roach). Following the October 4 start-up testing, the system was manually shut down pending. test evaluation. Upon receipt of test results, the system began full operation in catalytic mode on October 23, 2006. During the period that the HCVES and AS system were inoperative, monitoring of free product accumulation in the remediation wells continued and, where present, LPH was removed from the subsurface by manual bailing (temporarily stored in the West Tank Farm above - ground storage tank per SJVAPC permit) and mechanical extraction using a mobile tanker equipped with a vacuum pump. The volume of LPH removed is included in the totals expressed above.

(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, 2006 through December 31, 2006 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 existing North Tank Farm (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, 2006 through December 31, 2006, the high capacity vapor extraction system (HCVES) removed approximately 92 tons of total petroleum hydrocarbon (TPH) mass and 0.5 tons of methyl tertiary butyl ether (MTBE) from the subsurface. A cumulative total of 3,825 and 20 tons of hydrocarbons and MTBE, respectively, have been removed to date. Approximately 3,408 gallons of liquid phase hydrocarbons (LPH) were removed during the reporting period via stinging of selected wells and as vapor condensate. 299 West Hillcrest Drive Telephone: (805) 373 -9063 Suite 220 Facsimile: (805) 373 -9073 Thousand Oaks, California 91360 e -mail: miabrenz @thesourcegroup.net Mr. John T. Mitchell, Kern County District Attorney's Office March 28, 2007 Annual Remediation Summary Report (2006) Page 2 Assessment Activities - As requested by the CVRWQCB in a letter to World dated March 20, 2006, World conducted a drinking water well survey west of the PG &E Kern Steam Plant property as well as prepared a workplan for the installation of additional groundwater monitoring wells for the purpose of monitoring site constituents west/northwest of the Sunland site. SGI submitted the document entitled Well Installation Workplan and Water Well Survey Summary to the CVRWQCB on July 13, 2006. This document presented the results of the water well survey as well as outlined the proposed installation of groundwater monitoring well clusters at three locations west of the Sunland and PG &E sites. SGI's workplan was approved by the CVRWQCB in a letter to World dated September 6, 2006. Following CVRWQCB approval of the Well Installation Workplan, World secured an access agreement with PG &E and SGI completed necessary well permitting, drilling subcontract, and pre -field activities in late 2006. Well installation was completed in early 2007, and will be documented within the Annual Remediation Summary Report for calendar year 2007. REMEDIAL ACTIVITIES FOR 2006 Remedial activities at the former Sunland Oil 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 influent vapor treatment system and operation of the HCVES and AS systems started on September 16, 1998. Construction activities related to installation of a thermal oxidizer and 4,000 gallon AST at the site began in early December 2004 and continued through April 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. Figure 3 shows the layout of existing remediation wells and the treatment compound locations. System Operations and Monitoring During the reporting period (January 1, 2006 through December 31, 2006), remedial operations were performed in accordance with the requirements contained in the operational permit(s). During the reporting period, the HCVES removed approximately 92 tons of petroleum hydrocarbons and 0.5 tons of MtBE. A cumulative total of 3,825 tons of hydrocarbons and 20 tons of MtBE have been removed to date (Figure 4 and 5). HCVES operations for the reporting period are summarized in Appendix A. Due to reduced influent hydrocarbon concentrations associated with ongoing remediation, and also the trend of regionally rising groundwater, the HCVES was converted from thermal to catalytic mode of operation in 2006. The HCVES and AS systems were manually shutdown on July 31, 2006. The catalyst was installed in September 2006 and start-up testing was 'performed on October 4, 2006 under the supervision of San Joaquin Valley Air Pollution Control District ( SJVAPCD). During the period that the HCVES and AS system were inoperative, monitoring of free product accumulation in the remediation wells continued and, where present, LPH was removed from the subsurface by manual bailing (temporarily stored in the West Tank Farm above - ground storage tank per SJVAPCD permit) and mechanical extraction using a mobile tanker equipped with a vacuum pump. Approximately 3,408 gallons of liquid phase hydrocarbons (LPH) were removed during the reporting period via stinging and /or as vapor condensate associated with the operation of the HCVES. Stinging was conducted from wells MW -16, SE- VE -47c, SE- VE -48c, GMX- ASNE -63b, GMX -ASNE- The Source Group, Inc. Mr. John T.

The total volume of LPH removed since December 1996 is approximately 12,294 gallons. LPH removal activities are summarized in Appendix A. Air sparging was used for the remediation of dissolved phase hydrocarbons as well as the enhancement of vapor phase hydrocarbon recovery. Wells SE- AS -31d, SE- AS -45c, SE- AS -46c, SE- AS -86c, SE- AS -87c, SE- AS -88c, SE- AS -89c, TSG- AS -104c, TSG- AS -105c, TSG- AS -106c and TSG- AS -108c have either been installed expressly for this purpose, or subsequently adapted, and were all employed in air sparging during the reporting period. Monitoring of subsurface conditions was performed 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. Individual remediation wells were monitored for groundwater and product levels, hydrocarbon concentrations in the vapor stream, vacuum, and condensate /product removal activities once. a month. Vapor samples were collected from the oxidizer inlet header(s) for laboratory analysis once a month. From weekly data and monthly data, the system was adjusted to optimize removal of subsurface contaminants. ASSESSMENT ACTIVITIES As requested by the CVRWQCB in a letter to World dated March 20, 2006, World conducted a drinking water well survey west of the PG &E Kern Steam Plant property as well as prepared a workplan for the installation of additional groundwater monitoring wells for the purpose of monitoring site constituents west/northwest of the Sunland site. SGI submitted the document entitled Well Installation Workplan and Water Well Survey Summary to the CVRWQCB on July 13, 2006. This document presented the results of the water well survey as well as outlined the proposed installation of groundwater monitoring well clusters at three locations west of the Sunland and PG &E sites. SGI's workplan was approved by the CVRWQCB in a letter to World dated September 6, 2006. Following CVRWQCB approval of the Well Installation Workplan, World secured an access agreement with PG &E and SGI completed necessary well permitting, drilling subcontract, and pre - field activities in late 2006. Well installation was completed in early 2007, and will be documented within the Annual Remediation Summary Report for calendar year 2007 GROUNDWATER MONITORING Groundwater monitoring and sampling events were performed in March and September 2006. 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 and 2. Over the reporting period, the calculated groundwater gradient ranged from 0.010 feet/foot to 0.012 feet/foot to the northwest, away from the Kern River, which is consistent with the gradient measured The Source Group, Inc.

(World), The Source Group, Inc. (SGI) submits this Second Half 2007 Remediation Progress Report for the former Sunland Oil Refinery located in Bakersfield, California. Included with this report are the following: 1. Site location map (Figure 1); 2. Site map showing site -wide remediation well locations (Figure 2); 3. Cumulative vapor -phase hydrocarbon removal graph and MtBE removal graphs (Figures 3 and 4 respectively); 4. Graph showing high capacity vapor extraction system (HCVES) and air sparge (AS) system status and hydrocarbon mass removed during the Second Half 2007 reporting period (Figure 5); 5. Second Half 2007 HCVES, AS system, and liquid -phase hydrocarbon (LPH) recovery summary (Table 1); 6. Monthly HCVES and AS system operational data summaries for the reporting period (Tables 2a through 2g and Table 3); 7. Analytical laboratory reports and chain -of- custody records for vapor samples collected during the reporting period (Attachment A); 8. Individual well vapor concentration and vacuum data (Attachment B); 9. Copies of Waste Manifest forms (Attachment C); and 10. Daily field logs (Attachment D). The HCVES system operated in flare mode approximately 2,717.1 hours during the reporting period. An estimated 15.8 tons of hydrocarbons were extracted and destroyed by the John Zink Flare during this reporting period, bringing the cumulative total of hydrocarbons treated to 3,851.2 tons since the inception of vapor extraction at the site on March 22, 1996. An estimated 308.7 pounds of MtBE were extracted and destroyed by the John Zink Flare during the reporting period, bringing the cumulative total of MtBE treated to 19.8 tons since October 1996, the earliest date data was available for MtBE. 299 West Hillcrest Drive Telephone: (805) 373 -9063 Suite 220 Facsimile: (805) 373 -9073 Thousand Oaks, California 91360 e -mail: mlabrenz @thesourcegroup.net Mr. Anthony Medrano, CVRWQCB December 28, 2007 Second Half 2007 Remediation Progress Report (Revised November 10, 2008) Page 2 Approximately 12,600 gallons of liquid, including liquid phase hydrocarbons (LPH) and condensate generated during soil vapor extraction were removed from the site during the reporting period by Asbury Environmental Services and transported to Demenno Kerdoon in Compton, California for disposal /recycling. Approximately 598.5 gallons of LPH was collected by the HCVES (visually estimated at 5 percent of the liquid collected in the condensate knockout tanks) and a further 31.5 gallons of LPH was manually bailed or vacuumed from affected wells by a vacuum truck. In total, 630 gallons of LPH were removed from the site during the reporting period and the total amount of LPH removed since December 1996 is approximately 14,379 gallons. Monitoring of free product accumulation in the remediation wells continued and, where present, LPH was removed from the subsurface by manual bailing or mechanical extraction using a mobile tanker equipped with a vacuum pump. The volume of LPH removed is included in the totals expressed above. We appreciate your attention to this project and if you have any questions or need additional information, please contact Mr. John Hundley of World Oil Corp. at (562) 928 -0100 or the undersigned at (805) 373 -9063.

Deputy District Attorney Kern County District Attorney's Office Consumer and Environmental Protection Unit 1215 Truxtun Avenue Bakersfield, California 93301 Subject: Annual Remediation Summary Report (2007) January 1 through December 31, 2007 Former Sunland Oil Refinery, 2152 Coffee Road, Bakersfield, California Cleanup and Abatement Order No. 95 -7.02 Dear Mr. Mitchell: On behalf of World Oil Corp. (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, 2007 through December 31, 2007 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 (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, 2007 through December 31, 2007, the high capacity vapor extraction system (HCVES) removed approximately 32 tons of total petroleum hydrocarbon (TPH) mass and 0.2 tons of methyl tertiary butyl ether (MTBE) from the subsurface. A cumulative total of 3,858 and 20 tons of hydrocarbons and MTBE, respectively, have been removed to date. Approximately 2,295 gallons of liquid phase hydrocarbons (LPH) were removed during the reporting period via stinging of selected wells and 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 Annual Remediation Summary Report (2007) March 13, 2008 Page 2 Assessment Activities — Between January 15 and 21, 2007, three groundwater monitoring well clusters (TSG- MW- 114A/B /C through TSG- MW- 116A/B /C) were installed off site, west and northwest of the former Refinery site. The objective of the well installation activities was to provide additional vertical and lateral delineation of the western edge of the groundwater plume. One nested well cluster was installed west of the Refinery, in an area historically used for agricultural purposes. The two remaining nested well clusters were installed on the former PG &E Kern Steam Plant property, near the western property boundary. The wells were developed using a Smeal rig on January 24, 2007, and a wellhead survey was conducted by Evans Land Surveying and Mapping on February 22, 2007. Well installation details were submitted to the CVRWQCB by SGI in a report entitled Well Installation Report, dated February 28, 2007. REMEDIAL ACTIVITIES FOR 2007 Remedial activities at the former Sunland Oil 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 influent vapor treatment system and operation of the HCVES and AS systems started on September 16, 1998. Construction activities related to installation of a thermal oxidizer and 4,000 gallon AST at the site began in early December 2004 and continued through April 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. Figure 3 shows the layout of existing remediation wells and the treatment compound locations. System Operations and Monitoring During the reporting period (January 1, 2007 through December 31, 2007), remedial operations were performed in accordance with the requirements contained in the operational permit(s). During the reporting period, the HCVES removed approximately 32 tons of petroleum hydrocarbons and 0.2 tons of MtBE. A cumulative total of 3,858 tons of hydrocarbons and 20 tons of MtBE have been removed to date (Figure 4 and 5). HCVES operations for the reporting period are summarized in Appendix A. Due to mechanical problems with the thermal /catalytic oxidizer, SGI switched to the John Zink Flare in May. During the period that the HCVES and AS system were inoperative, monitoring of free product accumulation in the remediation wells continued and, where present, LPH was removed from the subsurface by manual bailing (temporarily stored in the. West Tank Farm above - ground storage tank per SJVAPCD permit) and mechanical extraction using a mobile tanker equipped with a vacuum pump. Approximately 2,295 gallons of liquid phase hydrocarbons (LPH) were removed during the reporting period via stinging and /or as vapor condensate associated with the operation of the HCVES. Stinging was conducted from wells MW -5, MW -7, SENE -47c, SENE -48c, GMX - ASNE -63b, GMX - ASNE-64b, GMX - ASNE -65b, TSG- VE -69b, TSG- VE -69c, TSG- VE -70c, ASNE -75c, TSG- VE -97, TSG -VE -100, TSG -VE -101, TSG -VE -111 and TSG- VE -113c and 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 14,589 gallons. LPH removal activities are summarized in Appendix A. The Source Group, Inc. Mr. John T. Mitchell, Kern County District Attorney's Office Annual Remediation Summary Report (2007) March 13, 2008 Page 3 Air sparging was used for the remediation of dissolved phase hydrocarbons as well as the enhancement of vapor phase hydrocarbon recovery. Wells AS -73D, AS -74D, AS -75D, AS -76D, AS- 77, AS -78c, AS -79D, AS -80c, AS-81D, SE- AS -86c, SE- AS -87c, SE- AS -88c, SE- AS -89c, TSG -AS- 103c, TSG- AS -104c, TSG- AS -105c, TSG- AS -106c, TSG- AS -107c and TSG- AS -108c have either been installed expressly for this purpose, or subsequently adapted, and were all employed in air sparging during the reporting period. Monitoring of subsurface conditions was performed 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. 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 2007 Between January 15 and 21, 2007, three groundwater monitoring well clusters (TSG- MW- 1 14A/B /C through TSG- MW- 1 16A/B /C) were installed off site, west and northwest of the former Refinery site. The objective of the well installation activities was to provide additional vertical and lateral delineation of the western edge of the groundwater plume. One nested well cluster was installed west of the Refinery, in an area historically used for agricultural purposes. The two remaining nested well clusters were installed on the former PG &E Kern Steam Plant property, near the western property boundary. Each well cluster consisted of three well casings, including an A- casing (screen depths ranging from 78 to. 130 feet bgs), a B- casing (screen depths ranging from 160 to 175 feet bgs), and a C- casing (screen depths ranging from 198 to 208 feet bgs). For each well cluster, the A- casing was installed within a dedicated boring. The B- casings and C- casings for each well cluster were installed as nested casings within a common borehole. The wells were developed using a Smeal rig on January 24, 2007, and a wellhead survey was conducted by Evans Land Surveying and Mapping on February 22, 2007. Well installation details were submitted to the CVRWQCB by SGI in a report entitled Well Installation Report, dated February 28, 2007. The wells were included within the semi - annual groundwater monitoring and sampling events conducted during 2007. GROUNDWATER MONITORING Groundwater monitoring and sampling events were performed in April and October 2007. 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 and 2. The Source Croup, Inc. Mr. John T. Mitchell, Kern County District Attorney's Office Annual Remediation Summary Report (2007) March 13, 2008 Page 4 Newly installed groundwater monitoring well clusters TSG- MW- 114A/B /C through TSG- MW- 116A/B /C were first sampled during the first and second half 2007 sampling events. Petroleum hydrocarbon constituents were not detected within groundwater collected from wells TSG- MW- 1 14A/B /C or TSG - MW-116A/B/C. Petroleum hydrocarbon constituents were detected within the B- casing and C- casing at well TSG -MW -115. Benzene was detected at 22 pg /L and 15 pg /L in TSG- MW -115C during the first half and second half 2007 sampling periods, respectively. MtBE was detected at 110 pg /L and 130 pg /L within TSG- MW -115B during the first half and second half 2007 sampling periods, respectively. Over the reporting period, the calculated groundwater gradient ranged from 0.006 feet /foot to 0.009 feet/foot to the northwest, away from the Kern River, which is consistent with the gradient measured in previous years. Groundwater data, summarized in the 2007 Semi - Annual Groundwater Monitoring and Status Reports, are presented in Appendix B. Groundwater contour and hydrocarbon concentration maps for 2007 are included in Appendix C. SCHEDULE Operation of the remediation system and semi annual groundwater monitoring will continue in 2008. The next groundwater monitoring and sampling event is scheduled for April 2008.

DRAFT Fact Sheet on Cleanup Activities for Former Sunland Refinery 2152 Coffee Road, Bakersfield, California November 2008 Summary The Central Valley Regional Water Quality Control Board (Water Board) has prepared this Fact Sheet to provide the public with an update on soil and groundwater cleanup activities being conducted at the Former Sunland Refinery facility in Bakersfield, California. Background The Former Sunland Refinery (the Site) is located at 2152 Coffee Road in Bakersfield, California, at the intersection of Coffee Road and the Atchison Topeka and Santa Fe Railroad. The Site covers approximately 200 acres, and was comprised of a main refinery area, three tank farms used for bulk storage of feedstocks and refined products (designated the South, West, and North Tank Farms) and support infrastructure including wastewater ponds and maintenance /storage areas. The Former Sunland Refinery operated from 1923 to 1995. The main refinery facilities included crude oil processing towers and a catalytic reformer unit. World Oil Corp. purchased the Sunland Refinery in 1975 and operated the facility until its closure in 1995. While operating, the facility refined crude oil into numerous fuel products including gasoline, diesel, kerosene, and jet fuel. Following the closure of the refining facility in 1995, decommissioning and demolition of the refinery and tank farms located south of the Atchison Topeka and Santa Fe Railroad occurred from 1995 through 1999. With the exception of the fire water system (fire water tank and piping), all above ground refinery infrastructure was removed from the site. Above ground infrastructure (tanks and pipelines) located within the tank farm north of the railroad (North Tank Farm) was removed in 2006 and 2007. The land use in the surrounding area is generally commercial and industrial, with some residential. Page 1 of 3 During the refinery's approximately 70 years of operation, petroleum hydrocarbons were released into the soil underlying the Site. Hydrocarbon contaminants migrated down through the soil, encountering and impacting groundwater beneath the Site. The Water Board is the lead agency overseeing the investigation and cleanup at this Site. Wastewater Pond Closure Wastewater from the former refinery was discharged into wastewater ponds located on the former West Tank Farm. Pond closure was undertaken in 1997 and consisted of removal of residual pond bottom wastes, removal of the concrete pond liner and subsequent soil and groundwater assessment in the vicinity of the ponds. In February 1998, the Water Board determined that closure activities associated with the wastewater disposal ponds were adequately completed. Site Investigations Under Water Board oversight, World Oil Corp. has conducted extensive onsite and offsite investigations to define the extent of soil and groundwater contamination beneath the Site and areas down - gradient of the Site. To date 116 groundwater monitoring and remediation wells have been installed at the site. The investigations detected petroleum hydrocarbon compounds in both soil and groundwater beneath the Site and downgradient of the Site to the west / northwest. The investigations indicated that the source area exists on the Site, beneath the former refinery area and former South and West Tank Farms, located south of the Atchison Topeka and Santa Fe Railroad. Investigations off -site have determined that dissolved phase hydrocarbon constituents extend offsite in groundwater to the west / northwest of the Site approximately 2,400 feet. Hydrocarbon constituents have been detected in groundwater underlying the Former Kern Steam Plant located northwest of the Site. The lateral extent of groundwater impact to the northwest has not yet been defined. Primary contaminants of concern within soil and groundwater include petroleum hydrocarbons in the gasoline, diesel and oil range, aromatic hydrocarbons including benzene, and the fuel additive methyl tertiary -butyl ether (MtBE). Total petroleum hydrocarbons as gasoline are present in areas underlying the Site at concentrations that exceed taste and odor thresholds. Benzene and MtBE are present in groundwater underlying portions of the Site at concentrations that exceed Primary Maximum Contaminant Levels (MCLs) for drinking water. The shallow groundwater within the Site vicinity typically flows in a north /northwest direction. Shallow groundwater beneath the Site is not used as a drinking water supply; as the City of Bakersfield (Vaughn Water) supplies drinking water to the Site and neighboring areas. Cleanup Activities Remedial activities at the Former Sunland Refinery began on March 22, 1996. The cleanup actions and current status of each action are summarized as follows: Soil Vapor Extraction (SVE) System. In 1996, World Oil Corp. installed a soil. vapor extraction (SVE) system at the Site, and expanded the system to a High Capacity Vapor Extraction System (HCVES) in 1998. The HCVES is capable of large scale removal and destruction of fuel hydrocarbons utilizing a candle flare or a thermal oxidizer. The system is designed to remove total petroleum hydrocarbons and associated constituents from unsaturated soil. World continues to operate the HCVES system. 2. Air Sparging (AS) System. Concurrent with SVE operations, World installed an air sparging system which injects air into the underlying groundwater. Air sparging volatilizes hydrocarbon constituents contained Page 2 of 3 within the groundwater. Hydrocarbon constituents which are volatized from groundwater and subsequently migrate into shallower unsaturated soils are captured using vapor extraction and processed /destroyed by the abatement device (flare or thermal oxidizer). The AS well network is designed to remove volatile hydrocarbon constituents in groundwater that are migrating in a northwesterly direction. World continues to operate the air sparging system. Free Product Removal. When present in onsite wells, liquid petroleum hydrocarbon or LPH is removed from affected wells by either bailing, pumping, or vacuum extraction. LPH removed from the subsurface is temporarily stored in an above ground storage tank (AST) onsite and subsequently recycled at regular intervals: Monitored Natural Attenuation. Dissolved phase contaminants in groundwater are reduced over time through a process called natural attenuation. World continues to monitor wells throughout the plume area to verify the effectiveness of natural attenuation in reducing petroleum hydrocarbon concentrations. Project Documents Site investigation and remediation documents and other Site documents are available at the Water Board offices. Water Board Oversight The Water Board oversees more than 000 site cleanup cases in the Central Valley, including more than 000 leaking underground fuel tank cases. Water Board staff direct investigation or cleanup work and set cleanup standards under Water Code authority. Responsible parties (e.g. past operators) propose specific measures, perform the actual work, and submit technical reports documenting task completion. As part of this process, we circulate key documents, such as draft cleanup plans, to interested persons and provide an opportunity for comment on these documents. Interested persons include other agencies, local officials, non - profit organizations, and interested landowners and resident /occupants in the Site vicinity.

Location: Former Sunland Refinery, 2152 Coffee Road, Bakersfield, California Client Contact/Phone No.: Mr. John Hundley/ (562) 928 -0100 Consulting Co. /Contact Person /Phone No.: The Source Group, Inc. / Mark Labrenz I (805) 373 -9063 The Source Group Project No.: 02 -WOC -085 Agency /Regulatory ID No.: RWQCB - Central Valley Region / Mr. Daniel Carlson / File #CAO 95 -702 WORK PERFORMED (January 2008 through May 2008): 1. Wayne Perry, Inc. (WPI) measured groundwater (and liquid petroleum hydrocarbon [LPH] levels, when present) in the groundwater monitoring wells on March 24, 2008. 2. WPI purged and sampled on- and off -site groundwater monitoring wells on March 25 through 28, 2008. 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. SGI operated the high capacity vapor extraction system (HCVES) utilizing the John Zink flare as the primary abatement device during the first half 2008 monitoring period. SGI is currently corresponding with the San Joaquin Valley Air Pollution Control District (SJVAPCD) regarding permit requirements necessary to replace two entrainment knock out tanks within the South Tank Farm remediation compound. For details of the remediation operations please see the First Half 2008 Remediation Progress Report prepared by SGI. 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, and in addition, performed routine bailing of LPH from affected wells during the first half 2008. 5. SGI conducted a soil gas survey at the former Sunland Refinery from March 31 through April 10, 2008: The soil gas survey was conducted in order to assess the presence of volatile organic compounds (VOCs) in near - surface soil in the vicinity of the former refinery/STF and the former WTF area (currently the Pan Pacific Petroleum facility). Soil gas samples were collected from 58 discrete locations within the former Refinery area at two depth intervals (5 feet and 15 feet below ground surface). The remediation system was shut down prior to testing to allow the subsurface to equilibrate prior to soil vapor testing. The air sparge systems were shut down on March 17, 2008 (two weeks prior to testing) and the soil vapor extraction system was shut down on March 24, 2008 (one week prior to testing). Soil vapor probes were installed from March 31 through April 4. Soil gas samples were collected from April 2 through April 10. Following the soil vapor testing, the system was temporarily re- started on April 11, 2008. However, indications based on vacuum readings showed a potentially broken conveyance line (assumed a soil vapor probe had been advanced through the conveyance line), and the system was shut down. Testing within the following week showed that conveyance lines were not broken during the testing and the system was re- started on April 24, 2008. Soil gas survey results are presented in a report entitled Results of Soil Gas Survey, Former Sunland Oil Refinery (SGI, May 13, 2008), and will be submitted to the Central Valley Regional Water Quality Control Board in a separate submittal. 6. As requested by the Central Valley Regional Water Quality Control Board (CVRWQCB) in a letter to World Oil Corp. dated November 28. 2006, additional fuel oxygenate analysis was performed on groundwater samples collected from well clusters SGI -MW -114 A/B /C, SGI -MW -115 A/B /C, and SGI -MW -116 A/B /C. Tertiary butyl alcohol (tBA), di- isopropyl ether (DIPE), ethyl tertiary butyl ether (EtBE), and tertiary amyl methyl ether (TAME) were analyzed during first half 2008 sampling episode (Table 2). In addition, the first The Source Group, Inc. Date: May30, 2008 half 2007 and second half 2007 additional fuel oxygenate results are also included within this submittal and summarized in Table 5. The previously identified fuel oxygenates were not detected in groundwater above the method detection limits within any of the three sampling events. Methanol and ethanol were not analyzed during the previous reporting period; however, groundwater from the three well clusters will be analyzed during the upcoming sampling events (second half 2008 and first half 2009) for methanol and ethanol. WORK PROPOSED FOR NEXT PERIOD (June 2008 through December 2008): 1. Complete groundwater gauging, purging, and sampling in August 2008. 2. Continue operation and maintenance of the high capacity vapor extraction system (HCVES) and air sparge (AS) system. Continue LPH removal from affected on -site wells using a vacuum truck and/or stingers. 3. Remediation system maintenance will be conducted during the second half of 2008 and include the replacement of two existing entrainment knock out tanks. The current entrainment knock out tanks are approximately 10 -years old and are showing signs of wear. San Joaquin Valley Air Pollution Control District has been notified of the planned replacement and is currently in the process of making a determination as to the need for changes to the existing Permit to Operate. 4.

Page 7 of 7 The Source Group, Inc. Appendix A Groundwater Monitoring Procedures The Source Group, Inc. Date: May 30, 2008 GROUNDWATER MONITORING PROCEDURES FORMER SUNLAND OIL REFINERY 2152 Coffee Road, Bakersfield, CA Groundwater Gauging. Each well was located and inspected prior to gauging by Wayne Perry, Inc. (WPI). Using a Solinstrm 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, California. 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 2008 waste recycling /disposal documentation is provided within Appendix E of this report. In addition, waste recycling /disposal documentation for first half 2007 and second half 2007 monitoring and sampling events are also included within Appendix E. The Source Group, Inc.

(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, 2007 through December 31, 2007 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 (Figure 2). 1 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, 2007 through December 31, 2007, the high capacity vapor extraction system (HCVES) removed approximately 30 tons of total petroleum hydrocarbon (TPH) t mass and 0.3 tons of methyl tertiary butyl ether (MTBE) from the subsurface. A cumulative total of 3,856 and 20 tons of hydrocarbons and MTBE, respectively, have been removed to date. Approximately 1,680 gallons of liquid phase hydrocarbons (LPH) were removed during the reporting period via stinging of selected wells and 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 13, 2008 Annual Remediation Summary Report (2007) Page 2 1 Assessment Activities - No additional assessment activities were performed in relation to the ' former Sunland Refinery site during calendar year 2007. ' REMEDIAL ACTIVITIES FOR 2007 Remedial activities at the former Sunland Oil 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 ' influent vapor treatment system and operation of the HCVES and AS systems started on September 16, 1998. Construction activities related to installation of a thermal oxidizer and 4,000 gallon AST at the site began in early December 2004 and continued through April 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. Figure 3 shows the layout of existing remediation wells and the treatment compound locations. ISystem Operations and Monitorin During the reporting period (January 1, 2007 through December 31, 2007), remedial operations ' were performed in accordance with the requirements contained in the operational permit(s). During the reporting period, the HCVES removed approximately 30 tons of petroleum hydrocarbons and 0.3 tons of MtBE. A cumulative total of 3,856 tons of hydrocarbons and 20 tons of MtBE have been ' removed to date (Figure 4 and 5). HCVES operations for the reporting period are summarized in Appendix A. Due to mechanical problems with the thermal /catalytic oxidizer, SGI switched to the John Zink Flare in May. During the period that the HCVES and AS system were inoperative, monitoring of free product accumulation in the remediation wells continued and, where present, LPH was removed from the subsurface by manual bailing (temporarily stored in the West Tank Farm above - ground storage tank per SJVAPCD permit) and mechanical extraction using a mobile tanker equipped with a vacuum pump. ' Approximately 1,680 gallons of liquid phase hydrocarbons (LPH) were removed during the reporting period via stinging and/or as vapor condensate associated with the operation of the HCVES. Stinging was conducted from wells MW -5, MW -7, SE- VE -47c, SE- VE -48c, GMX - ASNE -63b, GMX- ' ASNE -64b, GMX - ASNE -65b, TSG- VE -69b, TSG- VE -69c, TSG- VE -70c, ASNE -75c, TSG- VE -97, TSG -VE -100, TSG -VE -101, TSG -VE -111 and TSG- VE -113c and 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 12,246 gallons. LPH removal activities are summarized in Appendix A. ' Air sparging was used for the remediation of dissolved phase hydrocarbons as well as the enhancement of vapor phase hydrocarbon recovery. Wells AS -73D, AS -74D, AS -75D, AS -76D, AS- 77, AS -78c, AS -79D, AS -80c, AS -81 D, SE- AS -86c, SE- AS -87c, SE- AS -88c, SE- AS -89c, TSG -AS- 103c, TSG- AS -104c, TSG- AS- 105c, TSG- AS -106c, TSG- AS -107c and TSG- AS -108c have either been installed expressly for this purpose, or subsequently adapted, and were all employed in air sparging during the reporting period. IThe Source Croup, Inc. Mr. John T. Mitchell, Kern County District Attorney's Office March 13, 2008 Annual Remediation Summary Report (2007) Page 3 Monitoring of subsurface conditions was performed 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. 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. GROUNDWATER MONITORING Groundwater monitoring and sampling events were performed in April and October 2007. 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 and 2. Over the reporting period, the calculated groundwater gradient ranged from 0.006 feet/foot to 0.009 feet/foot to the northwest, away from the Kern River, which is consistent with the gradient measured in previous years. Groundwater data, summarized in the 2007 Semi - Annual Groundwater Monitoring and Status Reports, are presented in Appendix B. Groundwater contour and hydrocarbon concentration maps for 2007 are included in Appendix C. SCHEDULE Operation of the remediation system and semi annual groundwater monitoring will continue in 2008. The next groundwater monitoring and sampling event is scheduled for April 2008.

SGI continued operation of the oxidizer in catalytic mode as the primary abatement device during the first half.2007 monitoring period. A. SGI continued air sparging at the former West Tank Farm (WTF), former South Tank Farm (STF) areas of the Sunland site as well as the PG &E property north of the railroad tracks, and in addition, performed routine bailing of LPH from affected wells during the first half 2007. 5. in response to a CVRWQCB letter to World dated March 20, 2006, World conducted a drinking water well survey west of the PG &E properly and prepared a workplan for the installation of additional groundwater monitoring wells for the purpose of monitoring site constituents westinorthwest of the Sunland site. SGI submitted Well Installation Workplan and Water Well Survey Summary to the CVRWQCB on July 13, 2006. This workplan was approved by the CVRWQCB in a letter to World dated September 6, .2006. World then secured an access agreement with PG &E and SGI completed necessary well permitting, drilling subcontract, and pre -field activities during second half 2006. The well clusters (TSG -MW- 114A/B/C through TSG- MW- 115AIB /C) were installed between January 15 and 21, 2007.

Each well was located and inspected prior to gauging by Wayne Perry, Inc. (WPI). Using a SolinstTM 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 1 10% of each parameter and ensure that groundwater representative of the aquifer was entering the well. r .I 'The bailer 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, California. 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 three laboratory- prepared trip (or travel) blanks. One trip blank was kept in the sample cooler and submitted to the laboratory with each set of 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.
