Subject: First Half 2008 Remediation Progress Report December 1, 2007 through April 30, 2008 Former Sunland Oil Refinery, 2152 Coffee Road, Bakersfield, California Cleanup and Abatement Order No. 95 -702 SJVAPCD Authority to Construct Permit No. S- 4294 -1 -1 Dear Mr. Carlson: On behalf of World Oil Corp. (World), The Source Group, Inc. (SGI) submits this First Half 2008 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 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 First Half 2008 reporting period (Figure 5); 5. First Half 2008 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 2e and Table 3); 7. Summary of Individual Well Data (Table 4) 8. Analytical laboratory reports and chain -of- custody records for vapor samples collected during the reporting period (Attachment A); 9. Individual well vapor concentration and vacuum data (Attachment B); 10. Copies of Waste Manifest forms (Attachment C); and 11. Daily field logs (Attachment D). The HCVES system operated in flare mode approximately 2,306 hours during the reporting period. An estimated 30.5 tons of hydrocarbons were extracted and destroyed by the John Zink Flare during this reporting period, bringing the cumulative total of hydrocarbons treated to 3,885.9 tons since the inception of vapor extraction at the site on March 22, 1996. An estimated 262 pounds of MtBE were extracted and destroyed by the John Zink Flare during the reporting period, bringing the cumulative total of MtBE treated to 19.9 tons since October 1996, the earliest date MtBE data was available. Approximately 12,400 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 299 West Hillcrest Drive Telephone: (805) 373 -9063 Suite 220 Facsimile: (805) 373 -9073 Thousand Oaks, California 91360 e-mail: mlabrenz @thesourcegroup.net Mr. Daniel Carlson, CVRWQCB First Half 2008 Remediation Progress Report May 30, 2008 Page 2 Compton, California for disposal /recycling. Approximately 620 gallons of LPH was collected by the HCVES (visually estimated at 5 percent of the liquid collected in the condensate knockout tanks). With the exception of product removal during the semi - annual groundwater monitoring event, in -well product was neither bailed nor removed via vacuum truck during the reporting period. In total, approximately 620 gallons of LPH were removed from the site during the reporting period and the total amount of LPH removed since December 1996 is approximately 15,629 gallons. 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.

Vice President, Environmental Affairs World Oil Corporation 9302 South Garfield Ave. South Gate, CA 90280 -3896 REVIEW OF 2006 AND 2007 SEMI- ANNUAL GROUNDWATER MONITORING AND STATUS REPORTS, REMEDIATION PROGRESS REPORTS, AND 2006 AND 2007 ANNUAL REMEDIATION SUMMARY REPORTS, FORMER SUNLAND OIL REFINERY, BAKERSFIELD, KERN COUNTY We reviewed the following reports prepared by The Source Group, Inc. (TSG) of Thousand Oaks, California and submitted to this office on behalf of World Oil Corporation (World): • 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, and • Annual Remediation Summary Report (2007) dated 13 March 2008. Our comments on the above reports are summarized below.. For reference, monitoring well locations are depicted in the enclosed Figure 3 from the Semi- Annual Groundwater Monitoring and Status Report — Second Half — 2007, dated 21 December 2007. • Select analytical results for groundwater samples collected in 2006 and 2007 are presented in the enclosed Table 1. Several results for methyl tertiary butyl ether. (MTBE) and benzene exceed their respective Primary and/or Secondary Maximum Contaminant Level for.public drinking water supply systems (§ 64444, Title 22, California Code of Regulations). California Environmental Protection Agency Cd Recycled Paper osT r5 t 'P� -ter «i ,Mr. John P. Hundley, P.G. - 2 - 25 August 2008 Based upon the analytical results of groundwater sampling, the lateral and vertical extent of the petroleum hydrocarbon degradation in groundwater has not yet been adequately defined. Analytical results of groundwater sampling now indicates that the plume extents to depths of at least 200 feet in the areas of wells SE- MW -20D, TSG MW -8313, and TSG- MW -115C and possibly deeper. In addition, the groundwater degradation extends at, least 2,900 feet west northwest (downgradient) of what is anticipated to be the main source area at the former Sunland refinery. With wells TSG - MW -115.6 and C located approximately 115 feet east of the western PG &E property boundary, it appears likely that the plume extends to the northwest, beyond the western PG &E property boundary, and beneath the adjacent property to the west. The remediation system at the site has been in operation since March 1996, a total of 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. By 10 October 2008, please submit the following to this office: An addendum report. addressing specific comments (open bullets) to the reports reviewed in the enclosed Regional Water Board staff memorandum, and A draft fact sheet on the investigative /remedial work completed to date and the findings. World shall also provide to this office a list of parcels, including Assessor Parcel Number (APNs), located within 500 feet of the site; the associated names and addresses of property owners and residents for each parcel, and any other interested parties or groups. For this purpose the "site" refers to properties directly impacted by or which overlie any portion of the known extent of petroleum hydrocarbons in soil or. groundwater. Once the draft fact sheet is approved by this office, World shall distribute the fact sheet to the property owners, residents, and other interested parties on the list described above. By 31 October 2008, please submit the following to this office: An 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, isopleth maps depicting concentration contours of all constituents of concern in each hydrostratigraphic unit identified and updated geologic cross - sections depicting geology, well construction details, analytical data on soil samples, and groundwater analytical results including isopleth maps depicting concentration contours of all constituents of concern in each hydrostratigraphic unit identified. The report shall provide sufficient detail to be the basis for and shall also propose additional investigative work to fully delineate the lateral and vertical extent of groundwater impacted by petroleum hydrocarbons, and A more extensive remediation progress report that includes, but is not necessarily limited to, 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, amount and type of hydrocarbon product(s) remaining in the subsurface including floating product on the water table; hydrocarbon vapor concentrations from individual wells and the high capacity vapor extraction system influent over time; graphical data presentations, such as isopleth concentration contours on plan view maps and cross Mr. Jahn P. Hundley, P.G. - 3 - 25 August 2008 sections, depicting changes over time in. the distribution of petroleum hydrocarbons and current conditions;. an evaluation of the impacts, both positive and negative, of recent fluctuations in the groundwater table elevation on remediation efforts; sufficient information, analysis and conclusions to support recommendations regarding changes to or why no changes to the remediation efforts are warranted; and an updated estimate as to the time required under currently known conditions to.complete remediation of the site. Additional comments are provided in the enclosed Regional Water Board staff review memorandum. We would like to emphasize that the number of comments addressed in the enclosed memorandum involves 10 technical report submittals covering a two -year period. It is not our intent, in preparing this review, to appear to diminish the efforts and accomplishments World has made thus far in recovering approximately 3,876 tons of petroleum hydrocarbon constituents from soil and groundwater. Once World and its consultant have had a chance to review this letter and enclosed memorandum, a meeting to discuss our comments, the general project status, and the future approach to the project may be beneficial. I would suggest this meeting be held prior to the above due dates. We look forward to this meeting and our future discussions. Please contact Daniel Carlson of this office at (559) 444 -2484 if you have any questions regarding this matter or to schedule a meeting. PO4��Vw' 'Wj"-,-7 RUSSELL W.

California Environmental Protection Agency �a Recycled Paper Former Sunland Oil Refinery - 2 - 25 August 2008 2006 Semi - Annual Groundwater Monitoring and Status Reports First Half 2006 Semi - Annual Groundwater Monitoring and Status Report Total petroleum hydrocarbons as gasoline (TPHg) concentrations from wells SE -MW- 23S and TSG- MW -113C were the highest reported during the March 2006 sampling event. Groundwater samples collected from wells SE -MW -23S and TSG- MW -113C are reported to have TPHg concentrations of 18,000 and 12,000 micrograms per liter (Ng /L), respectively. The concentration in SE -MW -23S is consistent with historical results. The concentration in TSG- MW -113C is significantly lower than the previous 1,200,000 pg /L reported for the second half of 2005. Neither well had detectable concentrations of methyl tertiary butyl ether (MTBE). The highest concentration of MTBE, 140 pg /L, was detected in well SE- AS /MW -28D. The second highest concentration of MTBE, 120 pg /L, was detected in well TSG -MW- 83A. This well is approximately 2,000 feet west - northwest (downgradient) of what is anticipated to be the main MTBE source area, the South Tank Farm (STF), at the former Sunland refinery. In our 20 March 2006 review letter regarding the Second Half 2005 Semi - Annual Groundwater Monitoring and Status Report, based upon an analysis of historic MTBE data across the site, Regional Water Quality Control Board (Regional Water Board) staff suggested that the "lagging" benzene associated with a "slug" type MTBE release may have reached its peak concentration in well GMX- MW -62D in September 2005. The results of the current monitoring event indicated that benzene was not detected in well GMX -MW -62D, which appears to confirm that the benzene "slug" in groundwater has now migrated past well GMX -MW -62D. Well GMX -MW -62D is very near well TSG= MW -83A, discussed above, which is approximately 2,000 feet west - northwest (downgradient).of the STF at the former Sunland refinery. • Groundwater elevations at the site peaked in September 1999 and then declined until after March 2005 at which time groundwater elevations began to rise. Since March 2005, the elevations rose. approximately 15 to 20 feet in wells not in the immediate vicinity of active air sparging and vacuum extraction activities. • The groundwater flow direction during this monitoring event was. generally to the northwest at a gradient of approximately 0.010. This is in general agreement with . recent monitoring results. Second Half 2006 Semi - Annual Groundwater Monitoring and Status Report TPHg concentrations from wells SE- MW -20S and SE- MW -23D were the highest reported during the October 2006 sampling event. Groundwater samples collected from wells SE- MW -20S and SE -MW -23D are reported to have TPHg concentrations of 5,700 and 16,000 pg /L, respectively. The concentration in SE- MW -20S is consistent with historical results. The concentration in SE -MW -23D is slightly higher than the previous monitoring period, but is significantly lower than most historical results. MTBE Former Sunland Oil Refinery - 3 - 25 August 2008 was detected in well SE- MW -20S at .a concentration of 16 lag /L, but was not detected in well TSG- MW -23D. The highest concentration of MTBE, 230 lag /L, was detected in well TSG- MW -83A. The second highest concentration of MTBE, 76 lag /L, was detected in two wells: SE- AS/MW-28(D) and TSG- MW -83B. Wells TSG -MW -83A and B are approximately 2,000 feet west - northwest (downgradient) of what is anticipated to be the main MTBE source area, the STF, at the former Sunland refinery. • The results of the subject monitoring event indicated that benzene was again not detected in well GMX- MW -62D, which appears to further confirm that the benzene "slug" in groundwater has now migrated past well GMX -MW -62D. Well GMX -MW -62D is very near well TSG -MW -83A, discussed above, which is approximately 2,000 feet west - northwest (downgradient) of what is anticipated to be the main MTBE source area, the STF, at the former Sunland refinery. • Groundwater elevations at the site peaked in September 1999 and then declined until March 2005 at which time groundwater elevations began to rise. Since March 2005, the elevations continued to rise. Since the previous monitoring report, groundwater elevations rose approximately 5 to 12 feet in wells not in the immediate vicinity of active air sparging and vacuum extraction activities. • The groundwater flow direction during.this monitoring event was generally to the northwest at a gradient of approximately 0.012. This in general agreement with historic monitoring results. 2006 Semi - Annual Remediation Progress Reports First Half 2006 Remediation Progress Report • The high capacity vapor extraction system (HCVES) operated approximately 2,440 hours during the reporting period (67 percent of the time). • An estimated 134,310 pounds of hydrocarbons were extracted and destroyed by a thermal oxidizer during the reporting period. This brings the cumulative total of hydrocarbons treated to 7,579,730 pounds since vapor extraction was initiated at the site on 22 March 1996. • An estimated 1,056 pounds of MTBE was extracted and destroyed by the thermal oxidizer during the reporting period. This brings the cumulative total of MTBE treated to 39,158 pounds since October 1996; the earliest date data was available for MTBE. • Approximately 2,070 gallons of liquid petroleum hydrocarbons (LPH) was collected by the HCVES and from affected wells by a vacuum truck. As of the reporting period, the total amount of LPH removed since December 1996 is approximately 10,676 gallons. Former Sunland Oil Refinery - 4 - 25 August 2008 Second Half 2006 Remediation Progress Report • The HCVES operated approximately 2,061 hours during the reporting period (40 percent of the time). • An estimated 57,557 pounds of hydrocarbons were extracted and destroyed by a thermal oxidizer during the reporting period. This brings the cumulative total of hydrocarbons treated -to 7,637,287 pounds since vapor extraction was initiated at the site on 22 March 1996. • An estimated 12 pounds of MTBE was extracted and destroyed by the thermal oxidizer during the reporting period. This brings the cumulative total of MTBE treated to 39,170 pounds since October 1996; the earliest date data was available for MTBE. • Approximately 1,180 gallons of LPH was collected by the HCVES and an additional 78 gallons of LPH manually bailed or vacuumed from affected wells by a vacuum truck. As of this reporting period, the total amount of LPH removed since December 1996 is approximately 11,934 gallons. • Operational time during this reporting period was reduced due to conversion of the . HCVES from thermal to catalytic mode of operation. The Report indicates the. HCVES was off line from 31 July 2006; the catalyst installed in September 2006; and start-up testing was performed on 4.October 2006 under the supervision of San Joaquin Valley Air Pollution Control District staff. During the conversion, LPH continued to be collected from affected wells. o The language of the text suggests 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. o 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. 2006 Annual Remediation Summary Report • For calendar year 2006, approximately 86 tons of hydrocarbons and 0.5 tons of MTBE were removed by the HCVES from the subsurface below the former Sunland refinery site. Approximately 2,832 gallons of LPH were also removed via stinging of selected wells and as vapor condensate. • In response to a request from our office, TSG conducted a drinking water well survey west of the PG&E Kern Steam Plant property and also prepared a workplan for the installation of additional groundwater monitoring wells to monitor site constituents Former Sunland Oil Refinery - 5 - 25 August 2008 west/northwest of the former Sunland refinery site. On 17 July 2006 TSG submitted to our office the document entitled Well Installation Workplan and Water Well Summary dated 13 July 2006. We approved the well installation workplan in our letter dated 6 September 2006. The Report indicated that pre - installation activities were completed in late 2006 and the well installation was scheduled for early 2007. 2007 Semi - Annual Groundwater Monitoring and Status Reports First Half 2007 Semi - Annual Groundwater Monitoring and Status Report Groundwater samples were collected for the first time from the new groundwater monitoring wells; TSG -MW -114, A/B /C; TSG -MW -115, A/B /C; and TSG -MW -116 A/B /C; installed in January 2007. These wells were installed to provide additional vertical and lateral delineation of the western edge of the contamination plume in groundwater. TPHg concentrations from wells SE- MW -23D and SE- MW -20D were the highest reported during the April 2007 sampling event. Groundwater samples collected from wells SE -MW -23D and SE- MW -20D are reported to have TPHg concentrations of 2,600 pg /L and 1,800 pg /L, respectively. The concentration in SE- MW -23D is lower than the previous monitoring period and is significantly lower than most historical results. The concentration in SE- MW -20D is consistent with historical results. MTBE was not detected in well TSG -MW -23D, but was detected in well SE- MW -20D at a concentration of 98 pg /L. • The highest concentration of MTBE, 110 fag /L, was detected in newly installed well TSG- MW -115B. This well is approximately 2,900 feet west - northwest (downgradient) of what is anticipated to be the main MTBE source area, the STF, at the former Sunland refinery. The second highest concentration of MTBE, 98 pg /L, was detected in well SE- MW -201D. • The highest concentration of benzene, 22 pg /L, was detected in newly installed well TSG- MW -115C. This well is approximately 2,900 feet west - northwest (downgradient) of what is anticipated to be the main source area at the former Sunland refinery. The second highest concentration of benzene, 5.8 pg /L, was detected in well TSG- MW -85C. In our 20 March 2006 review letter regarding the Second Half 2005 Semi - Annual Groundwater Monitoring and Status Report, based upon an analysis of historic MTBE data across the site, Regional Water Board staff suggested that the "lagging" benzene associated with a "slug" type MTBE release may have reached its peak concentration in well GMX- MW -62D in September 2005. The. results of the previous and current monitoring events indicated that benzene was not. detected in well GMX -MW -62D, which appears to again confirm that the referenced benzene "slug" in groundwater has now migrated past well GMX- MW -62D. Well GMX -MW -62D is approximately 2,000 feet west - northwest (downgradient) of what is anticipated to be the main MTBE source area (STF) at the former Sunland refinery. Former Sunland Oil Refinery - 6 - 25 August 2008 • Groundwater elevations at the site peaked in September 1999 and then declined. until March 2005 at which time groundwater elevations began to rise. Since March.2005, the elevations continue rise. Since the last monitoring report, groundwater elevations rose approximately 6 to 8 feet in wells not in the immediate vicinity of active air sparging and vacuum extraction activities. This brings the total rise in the groundwater surface from March 2005 until April 2007 to 30+ feet in wells not in the immediate vicinity of active air sparging and vacuum extraction activities. Other wells show an apparent rise of approximately 45 feet but how much of this apparent rise may be influenced by the remediation activities of air sparging and soil vapor extraction is not known. • The groundwater flow direction during this monitoring event was generally to the northwest at a gradient of approximately 0.009. This is in general agreement with recent monitoring results. o World failed to include analyses for oxygenates during the first semi - annual period 2007 groundwater 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 826013 and the results reported for all constituents for the next two monitoring events. Once the results are available and reviewed a determination can be made whether continuation of these analyses is warranted. Second Half 2007 Semi - Annual Groundwater Monitoring and Status Report • The highest TPHg. concentrations reported during the October 2007 sampling event are from wells SE- MW -23D and SE- MW -23S. Groundwater samples collected from wells SE -MW -23D and SE -MW -23S are reported to have TPHg concentrations of 30,000 and 3,100 pg /L, respectively. MTBE was not detected in either well. The highest concentration of MTBE, 210 pg /L, was. detected in well TSG- MW -83B. This well is approximately 2,000 feet west - northwest (downgradient) of what is anticipated to be the main MTBE source area at the former Sunland refinery. The second highest concentration of MTBE, 130 pg /L, was detected in well TSG -MW -1158. This well is approximately 2,900 feet west - northwest (downgradient) of what is anticipated to be the main MTBE source area at the former Sunland refinery. • The highest concentration of benzene, 15 pg /L, was detected in newly installed well TSG- MW -115C. This well. is approximately 2,900 feet west - northwest (downgradient) of what is anticipated to be the main source area at the former Sunland refinery. The second highest concentration of benzene, 8.7 pg /L, was detected in well SE -MW -23D. In our 20 March 2006 review letter regarding the Second Half 2005 Semi - Annual Groundwater Monitoring and Status Report, based upon an analysis of historic MTBE data across the site, Regional Water Board staff suggested that the "lagging" benzene associated with a "slug" type MTBE release may have reached its peak concentration in well GMX- MW -62D in September 2005. The results of the two previous and current monitoring events indicated that benzene was not detected in well GMX -MW -62D, which appears to further confirm that the referenced benzene "slug" in groundwater has Former Sunland Oil Refinery - 7 - 25 August 2008 now migrated past well GMX- MW -62D. Well GMX -MW -62D is approximately 2,000 feet west - northwest (downgradient) of what is anticipated to be the main MTBE source area, the STF, at the former Sunland refinery. • In this same 20 March 2006 review letter, Regional Water Board staff further suggested that based upon these same calculations the core of the MTBE "slug" should be located about 700 to. 1,000 feet downgradient of well GMX- MW -62D, at that time, or near the western PG &E property boundary. This estimate appears to have been correct based upon the detection of MTBE and benzene at concentrations that exceeds their respective Primary MCL for drinking water in new wells TSG -MW -115 B and C, constructed in January 2007, located near the PG &E boundary. • Using the same seepage velocity for MTBE of 0.8 to 1.1 feet per day, previously calculated by Regional Water Board staff, and continuing the migration to the northwest since March 2006, the "slug" of MTBE may have migrated to date an additional 600 to 800 feet downgradient of new wells TSG -MW -115 B and C and beneath the adjacent property. This new estimated extent of the plume is approximately 3,600 feet downgradient of what is anticipated to be the main MTBE source area at the former Sunland refinery South Tank Farm. • Groundwater elevations at the site peaked in September 1999 and then declined until March 2005 at which time groundwater elevations began to rise. For the first time since March 2005, groundwater elevations declined at the site. Since the last monitoring report, groundwater elevations declined approximately 6 to 10 feet in wells not in the immediate vicinity of active air sparging and vacuum extraction activities. • I reviewed groundwater elevations in wells located together and within and down gradient along the contamination plume. From these I calculated vertical hydraulic gradients. The vertical hydraulic gradient at wells GMX- MW -62(S) and TSG- MW -83B was calculated to be 0.094 and 0.157 for April and October 2007, respectively. The vertical hydraulic gradient at wells TSG- MW -115A and TSG- MW -115C was calculated to be 0.066 and 0.121 for April and October 2007, respectively. Comparison of groundwater elevations in the B and C wells of the TSG -MW -114 through 116 well clusters indicated negligible differences in wells TSG -MW -114 and 115. However, the difference in groundwater elevations for TSG- MW -116B and C were 5.12 feet lower and 6.48 feet lower in the C well in April and October 2007, respectively. The .B well is screened from 160 -170 feet below ground surface (bgs) and the C well is screened from 198 -208 feet bgs. Review of the continuous core log for well 116 B/C indicates silt (ML - 65% silt, 20% fine sand, and 15% clay) was encountered from 175 to 182 feet bgs, between the screened intervals of these wells. Additional zones logged as silty sand (with up to 25% silt) were also encountered in the interval between the screens in wells 116B and C. Collectively, this suggests some hydraulic separation may exist between the zones monitored by each well. • The groundwater -flow direction during this monitoring event was generally to the northwest at a gradient of approximately 0.006. This is in general agreement with recent monitoring results. Former Sunland Oil Refinery -8- 25 August 2008 o 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 VI). 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. o 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. Once the results are available and reviewed a determination can be made whether continuation of these analyses is warranted. 2007 Semi - Annual Remediation Progress Reports . First Half 2007 Remediation Progress Report • The HCVES. operated, in catalytic mode, approximately 2,815 hours during the reporting period (78 percent of the time). • An estimated 16.8 tons (33,600 pounds) of hydrocarbons were extracted and destroyed by the catalytic oxidizer during this reporting period. This brings the cumulative total of hydrocarbons treated to 3,835.4 tons since vapor extraction was initiated at the site on 22 March 1996. • An estimated 101 pounds of MTBE was extracted and destroyed by the catalytic oxidizer during the reporting period. This brings the cumulative total of MTBE treated to 19.6 tons since October 1996; the earliest date data was available for MTBE. • Approximately 1,682 gallons of LPH was collected by the HCVES and an additional 133 gallons of LPH was manually bailed or removed from affected wells by a vacuum truck. In total, 1,815 gallons of LPH were removed from the site during the reporting period and the total amount of LPH removed since December 1996 is approximately 13,749 gallons. • Table 3 in the Report fails to include 7" in the "Note" column for monitoring performed on 22 January 2007 indicating that HCVES influent samples were collected for laboratory analysis. Second Half 2007 Remediation. -Progress Report o 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. Former Sunland Oil Refinery - 9 - 25 August 2008 • An estimated 2.0 tons (40,000 pounds) of hydrocarbons were extracted and destroyed by the flare during the reporting period. This brings the cumulative total of hydrocarbons treated to 3,855.4 tons since vapor extraction was initiated at the site on 22 March 1996. • An estimated 328 pounds of MTBE was extracted and destroyed by the flare during the reporting period. This brings the cumulative total of MTBE treated to 1.9.8 tons since October 1996; the earliest date data was available for MTBE. o 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 Second Half 2007 Period Total, New LPH Project Total . 13,749 gallons 1,338 gallons 15,087 gallons (not 15,009 as reported) World needs to recheck the LPH calculations and amend the text and Table 1 of the Report as necessary. o Data within the Report indicates that the entire HCVES was off from 12 April 2007 through 6 June 2007; almost 2 months. World needs to provide an explanation of why the HCVES was off during this period. o In Table 2g, the AS System Process Summary lists the "Air Sparge Flow Rate Per Well" as 39,217 scfm, which appears incorrect. World needs to check and amend as necessary. o 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. o Figure 5 in the Report depicts periods when the HCVES, the South Tank Farm (STF) air sparging (AS), and WTF'AS systems are "On" or "Off'. 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. o 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. Former Sunland Oil Refinery _10- 25 August 2008 • In Attachment D, the first set of field vapor extraction monitoring logs do not identify the technician's name, initials, and date the readings were taken. o 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 [aboveground storage tank]. 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 system shut down note may belong on the 23 August 2007 field log. World needs to review and clarify. o Similar to the issue discussed in the previous comment, the 30 August 2007 HCVES / AS Monitoring Log does not indicate HVCES Blower 2 departure status, AS STF departure status, nor the AS WTF arrival and departure status. World needs to ensure that the HCVES / AS Monitoring Logs are properly completed in the field by personnel monitoring the system. o 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. o 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. o 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 on the Depth to Water and ,Depth to Product are present in the table. Examples in the 6 June 2007 measurements include wells AS -81 b and SE- MW -9(R); well MW -5 in the 15 August 2007 measurements. Similarly, there are 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. o World needs to provide an explanation as to why concentration or vacuum data for the vapor extraction wells (TSG —VE -90 through TSG- VE -96), located on PG &E property, are not included in the tables contained in Attachment B of the Report. o 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. Former Sunland Oil Refinery - 11 - 25 August 2008 2007 Annual Remediation Summary Report The Report indicates that for the calendar year 2007, the high capacity vapor. extraction system removed and destroyed approximately 30 tons of petroleum hydrocarbons and 0.3 tons of MTBE from the subsurface below the former Sunland refinery site. Approximately 1,680 gallons of LPH were also removed via stinging of selected wells and as vapor condensate. This brings the cumulative total to 3,856 tons and 20 tons of hydrocarbons and MTBE, respectively, removed to date. o 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. o 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. In the Annual Remediation Summary Report (2006) (2006 Summary under the heading Assessment Activities, the report summarizes our request for the installation of additional groundwater monitoring wells for the purpose of monitoring site constituents west and northwest of the former Sunland refinery site. Our request was made to further assess the lateral and vertical extent of groundwater impacted by petroleum hydrocarbons migrating from the Sunland site. The 2006 Summary Report also states that SGI submitted a workplan for well installations, that our office approved the workplan, and that SGl completed pre - drilling activities in late 2006. The 2006 Summary Report also stated, "Well installation was completed in early 2007, and will be documented within the Annual Remediation Summary Report for calendar year 2007'. However, no such documentation of the well installations was found in the Annual Remediation Summary Report for 2007. World should revise the Assessment Activities section of the Report to include a discussion of the installation of the three well clusters TSG- MW- 1 14A/B/C, - 115A/B /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. Although the analytical results of sampling these new wells are contained within Table 1 — Historical Groundwater Analysis and Gauging Results, and in the two Groundwater Hydrocarbon Concentration Maps within the Report, the results and conclusions should be discussed in the Report text 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, at depths from approximately 160 to 210 feet and 2,900 feet west - northwest (downgradient) of the anticipated source area of the former Sunland refinery. o On page 3, paragraph 1, the Report states in pertinent part, "Vapor samples were collected from the inlet header(s) for laboratory analysis once a month ". In my review of the two semi- annual remediation progress reports, there are no analytical results Former Sunland Oil Refinery -12- 25 August 2008 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 process /influent vapor samples were collected for analysis. o In addition, process /influent 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 could not be collected in April and June 2,007 due to "system off -line" and yet samples were apparently collected 21 May 2007 even though the entire remediation system was off - line from 13 April 2007 through 6 June 2007. Summary Comments • Selected results for groundwater samples collected in 2006 and 2007 are presented in the enclosed Table 1. Monitoring well locations are depicted in the enclosed Figure 3 from the Semi - Annual Groundwater Monitoring and Status Report — Second Half — 2007, dated 21 December 2007. Based upon the above, the lateral and vertical extent of the petroleum hydrocarbon contamination in groundwater has not yet been defined. Analytical results of groundwater sampling now indicates that the plume of degradation, which exceeds the Primary MCLs for some constituents, extents to depths of at least 200 feet in the areas of wells SE- MW -20D, TSG- MW -83B, and TSG- MW -115C and possibly deeper. In addition, the groundwater degradation extends at Feast 2,900 feet west northwest (downgradient) of what is anticipated to be the main MTBE source area at the former Sunland refinery. Based upon previous Regional Water Board staff estimates of the rate of contaminant plume migration, the plume may now have migrated to the northwest approximately 600 to 800 feet beyond wells TSG -MW -115 Band C. Since wells TSG- MW -115B and. C are located approximately 115 feet east of the western PG &E property boundary, it appears likely that the plume of groundwater degradation extends to the northwest beyond the western PG &E property boundary, and beneath the adjacent property to the west. o 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 Former Sunland Oil Refinery -13- 25 August 2008 maps depicting concentration contours of all constituents of concern in each hydrostratigraphic 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. o Based upon 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 Assessor Parcel Number (APNs), located within 500 feet of the site; the associated names and addresses of property. owners and /or 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. o 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 an updated estimate as to the time required under currently known conditions to complete remediation of the site.

Both reports were prepared and submitted by The Source Group, Inc. (SGI) of Thousand Oaks, California on behalf of World Oil Corporation (World). Our comments on these reports are presented below.. For reference, monitoring well locations are depicted in Figure 3 from the Semi - Annual Groundwater Monitoring, and Status Report – First Half– 2008 enclosed with the Regional W,?*— r -B^ ^rd staff revielm memorandum. First Half 2008.Groundwate'r'.Monitokng and Status Report • In this report, World included analytical results for wells TSG- MW- 114A -C, - 115A -C, and - 116A -C from the current and the past two monitoring events for some of the fuel oxygenates required in the Regional Water Board letter titled Well Installation Work Plan Review dated .6 September 2006. However, the report indicated that analyses for methanol and ethanol were not included but would be included in the second half 2008 and first half 2009 sampling events. In addition to ethanol and methanol, samples should also be analyzed. for 1,2 dichloroethane using USEPA Method 8260B and the results reported for the next two monitoring events. Once-the results are available and reviewed, a determination can be made whether continuation of these analyses is warranted; • The text of the report indicates that, "The previously identified fuel oxygenates were not detected in groundwater above the method detection limits within any of the three sampling events ".. This is incorrect, Table 5 of the report indicates that tert-Butyl alcohol was detected in well TSG- MW -115B during the 3 October 2007 sampling event at a concentration, of 13 yg /L. -A review ofthe.jaboratory reports contained within 'Appendix C confirmed that the 13 pg/L result is correct; "fir this`sarne section of the report, text; the -most recently iristalled wells, Which wer`e`-` sarh. pled for fuel oxygenates, are referred.to as SGI- MW- 114A -C, 'SGI =MW 115A =C, and SGI -MW - 116A -C.

For reference, monitoring Well lo6ation's,-are depicted in the enclosed, Figure 3 from the Semi-' Annual Groundwater Monitoring and Status Report — First Half — 2008. First Half 2008 Groundwater Monitoring and Status Report • The report documents activities performed from 1 January 2008 through 31 May 2008. The groundwater sampling event took place on 25-28 March 2008, • Since the last monitoring event in October 2007, groundwater elevations have declined approximately 5-7 feet in monitoring wells to the west and northwest of the Site and approximately 10-11 feet in the southeast portion of the Site, • The groundwater flow direction during this monitoring event was generally to the northwest at a gradient of approximately 0.005. This is in general agreement with recent monitoring results, • The highest TPHg concentrations reported,d u ring this sampling event are.frommells SE-MW-23S and-SE -'MW -23D with. concentrations of 18-,000 and 17,000 pg/L,,, respectively. MTBE, was not detected: in either well. However, total xylenes was: detected in well SE -MW -23D, .screened from 160.to 165 feet below ground surface, at a concentration of 3,650 pg/L, which exceeds the Primary Maximum Concentration Limit California Environmental Protection Agency Q? Recycled Paper Former Sunland Oil Refinery - 2 - 16 December 2008 of 1,750 pg /L established by the California,. Department of Public Health for public drinking water systems. Well SE- MW -23D is at the. former South Tank Farm, • The highest concentration'of.MTBE,� 120 yg /L,. was detected in. well TSG -MW -1156.

The . second- highest concentration .of "MTBE, 11,0 pg /L, was detected in well, TSG- MW -83B. This well is approximately. 2,000 feet west- northwest,(downgradient) of what.is anticipated to be the main MTBE source area at the former Sunland refinery., The MTBE results for these two wells are reasonably consistent with previous results, The highest concentration of benzene, 2.8 pg /L, was detected in well MW -19. This well is near the main source area at the former Sunland refinery. The second highest concentration of benzene, 2.0 pg /L, was detected in well TSG- MW -115C, located approximately 2,,900 feet west - northwest (downgradient) of the anticipated main source area, In this report, World included analytical results for wells TSG- MW- .114A -C, - 115A -C, and - 116A -C from the current and the past two monitoring events for some of the fuel oxygenates required in the Regional Water Board letter titled Well Installation Work Plan Review dated 6 September 2006. However, the report indicated that analyses for methanol* and ethanol were not included but would be included in the second half 2008 and`fi�sf half'2009-sampling events; In` addition to'"ethanol and'methanol,: samplesahould .also. be analyzed .for:1:;2 =' dichlor "oethane using:08EPA. Method 8260B.'and the _eesu Its, reported for all ~, T constituents for the -next two monitoring. events. 'Onceahedresults.'are available arid reviewed, a determination can be made whether continuation of these analyses is warranted, The text of the report indicates that, "The previously identified fuel oxygenates were not detected in groundwater above the method detection limits- within any of the three sampling events ". This is incorrect. Table 5 of the report indicates that tert-Butyl alcohol was detected in well TSG -MW -1158 during the 3 October 2007 sampling event at a concentration of 13 pg /L. A review of the laboratory reports contained within Appendix C confirmed that the 13 pg /L result is correct, In this same section of the report, the most recently installed wells, which were sampled for fuel oxygenates, are referred to as SGI- MW- 114A -C, SGI -MW - 115A -C, and SGI - MW - 116A -C. All other references to these wells in this report and in previous correspondence to this office has named these wells TSG- MW- 114A -C, TSG -MW - 115A -C, and TSG -MW - 116A -C, • In Table 4; the results"for�MTBE in well SE =MW =20(8) forthe'dates'of,6 October 2007 and 27 March 2008 are incorrectly reported as 0.005 milligrams�.per liter (mg /L). The correct results, for both these dates is <0.002 mg /L (i.e., not detected); Former Sunland Oil Refinery - 3 - 16 December 2008 • Several of the "Well Purging, Sampling and Inspection- Forms" contained within. Appendix D of the report indicate that all the turbidity values recorded during purging are -5.0, assumed to be nephelometric turbidity units. It is unclear why the recorded values would often be negative.. This was found:on the forms for:wells GMX- MW -60, TSG-MW -115A TSG- MW=114A; TSG- MW- 67A,1-.TSG= MW -67B; and TSG= MW- .11"6A. No instrument calibration logs were,found in.the report. Further,'the form. for well :TSG- MN 114A records` the turbidity of -5.0 for each of four casing-volumes, purged. However, in the "Comments" column of the form it states, "Water-cloudy purged.an extra casing volume." If the purge waterwas sufficiently cloudy to require the purging of an extra casing volume, how can the turbidity values of -5.0 be valid, and The report states that a soil gas survey was performed at the site on 31 March through 10 April 2008. The purpose of the survey was to assess the presence of volatile organic compounds (VOCs) and methane concentrations in near - surface soil in the vicinity of the former refinery, south tank farm, and west tankrfarm areas.. 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 air sparge (AS) systems were shutdown on 17 March 2008 (two weeks prior to testing) and the high capacity vapor extraction system (HCVES) was shutdown on 24 March 2008 (one week prior to testing) to allow the subsurface to, equilibrate prior to soil vapor testing. The probes were installed from 31 March through 4 April 2008 and soil gas samples were collected from 2 April through 10 April 2008. After.:some initial: restart problems were resolved, the remediation systems (AS and HCVES) were:: back in, operation on, 24. April 2008.

It is also my understanding that a copy of the risk assessment report will be submitted to this office when finalized. First Half 2008 Remediation Progress Report . ,.- • The report documents the remediation system operation and activities performed from 1 December 2007 through 30 April 2008. • The HCVES operated, in flare mode, approximately 2,306 hours during the reporting period (63 percent of the time). The reduced operating time during, this reporting period is due the HCVES and the AS system being offline for a period. to perform the soil gas survey at the site discussed above, •' An estimated 30.5ao.n5 -(61:,000-pp.unds) of hydrocarbons were extracted, and, destroyed by the-John Zink Flare.(flare) during.this reporting period. This brings,the cumulative total of hydrocarbons treated to 3,885.9 tons since vapor extraction was initiated at the site on 22 March 1996, Former Sunland Oil Refinery - 4- -16 December 2008 r • An estimated 262 pounds of MTBE was extracted and destroyed by the flare during the reporting' period. This brings the cumulative total of MTBE treated to 19.9 tons since October 1996;. the earliest date data was available for MTBE, • Approximately 620 gallons of liquid petroleum hydrocarbons (LPH) was collected by the HCVES during,the'reporting period. The report states that this brings the total- amount' of LPH removed since December 1996 to approximately 15,629 gallons.. However, a previous comment to the Second Half 2007 Remediation Progress Report suggested that the calculated project total LPH removed should be 15,087 gallons at the end of that reporting period. Therefore, I believe the actual total LPH removed is now actually 15,707 gallons, not the 15,629 reported, and • Table 4 of the report indicates that monitoring well MW -16 and ASNE -75c contained 11.15 feet and 2.53 feet of petroleum hydrocarbon product, respectively. However, the text of the report states, "With the exception of product removal during the semi - annual groundwater monitoring event, in -well product was neither bailed nor removed via vacuum truck during the reporting period ". With the accumulation of product in well MW -16, World needs to ensure that wells which are accumulating product are measured and the free product removed on a more frequent basis than semi - annually.
