Kern County District Attorney's Office I Consumer and Environmental Protection Unit 1215 Truxtun Avenue 'l Bakersfield, California 93301 · Subject: Annual Remediation Report January 1 through December 31, 2003 I Former Sunland Oil Refinery 2152 Coffee Road, Bakersfield, California Cleanup and Abatement Order No. 95-702 ! Dear Mr. Mitchell: Telephone I On behalf of World Oil Corp., (World), Earth Tech, Inc. has prepared this annual 562.95 ~. 2000 remediation summary report for the former Sunland Oil Refinery (Sunland) located in Bakersfield, California (Figure 1). The remediation data collected and F acs i mile monitoring activities conducted during January through December 2003 are summarized in this report. 5 6 2.9 51.210 0 I INTRODUCTION ,, i 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 i 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 report regarding the status of site i remediation efforts to contain and remediate groundwater and soil impacted by petroleum hydrocarbons under CAO No. 95-702. The Sunland facility is divided into three main areas: the former West Tank Farm (WTF), the former refinery plant/former South Tank Farm (STF), and the North Tank Farm (NTF) (Figure 2). I EXECUTIVE SUMMARY I Based on a review of the remedial activities performed during this reporting period, the following summary and conclusions are presented: I o Remedial Activi .ty - From January 1, 2003 through December 31, 2003, the high capacity vapor extraction system (HCVES) removed approximately 1,299,316 pounds (lbs) of total petroleum hydrocarbons I (TPH) as soil gas and ,925 lbs of methyl tertiary butyl ether (MTBE) E A R T H ~'~ 1' E C H I A '~ INTERNATIONAL LTD. COMPANY I Mr. John T. Mitchell, Esq. , 2 i Kern County District Attorney~ Offic~e March 30, 2004 from the subsurface. A cumulative total of 6,063,564 and 30,106 lbs of TPH and MTBE, respectively, have been removed to date (see Figures 3 I and 4). Approximately 1,318 gallons of liquid petroleum hydrocarbons (LPH) were removed during the reporting period via stinging of selected wells and/or as vapor condensate. I o Proposed Assessment Activities - Installation of four proposed off-site multi-nested groundwater monitoring wells located down gradient and I northwest of the site, at the Pacific Gas and Electric (PG&E) Kern Steam Plant, in order to define the leading edge of the MTBE plume in groundwater. Also, soil vapor extraction (dual-nested) and air-sparge I wells will be installed around the of the PG&E (triple-nested) perimeter sub-station located east of Coffee Road and north of the railroad tracks. The proposed air sparge (AS) and vapor extraction (VE) wells will be I connected to the existing treatment system (located at Refinery) the former via proposed subsurface a conveyance piping installed across old Coffee Road to an existing header (located on the North side of the railroad I tracks). In January 2004 Evans Land Surveying and Mapping will be surveying I the well elevations all existing remediation and groundwater casing on monitoring wells located within the former Refinery and South Tank Farm. I REMEDIAL ACTIVITY FOR 2003 I Soil and Groundwater Remediation Remedial activities at the former Sunland facility began on March 22, 1996 with vapor extraction and air sparging remediation systems. VE and AS systems were operated at the STF until June 19, 1998 and at the WTF until July 30, 1998. Installation of the HCVES replaced the former influent vapor treatment system I and operation of the HCVES and AS systems started on September 16, 1998. Figure 2 shows the treatment compound location. I During the reporting period (January 1 through December 31, 2003), remedial operations were performed in accordance with the requirements contained in the i operational permit(s). .During the reporting period, the HCVES removed approximately 1,299,316 and 1,925 lbs of hydrocarbons and MTBE, respectively. A cumulative total of 6,063,564 lbs of hydrocarbons and 30,106 lbs of MTBE I have been removed to date (Figures 3 and 4). HCVES operations for the reporting period are summarized in Appendix A. Approximately 1,318 gallons of liquid petroleum hydrocarbons (LPH) were removed during the reporting period via stinging (43.4 gallons) and/or as vapor condensate associated with the operation of the HCVES. LPH removal via I conducted from wells MW-9R, MW-16, SE-SVE 42c, SE-SVE-43c, stinging was E A R T H ~m,~ T E ¢ H I A ~I~CD INTERNATIONAL LTl>. COMPANY Mr. John T. Mitchell, Esq. 3 Kern County District Attomey's Office March 30, 2004 I SE-VE-47c, SE-VE-48c, SE-VE-73b, SE-VE-74b, SE-VE-75b, SE-VE-76b, during this reporting period. The total volume of LPH removed since December I 1996 is approximately 5,308 gallons. LPH removal activities are summarized in Appendix B. I During this reporting period, Earth Tech performed routine system operation and maintenance (O&M). A number of major equipment maintenance were conducted, including replacement of one blower, cleaning the flare burner tips, I replacement of valves on the wellfield manifolds, and replacement of knock out pumps. I AS conducted from March through July 2003. AS well AS-79c operations were was cycled 4 hours on, 8 hours off, within the ranges recommended by The Source Group in the SVE/AS Pilot Test Report (The Source Group, April 2002). I For this the AS in between June 1 reporting period, system operation was to July 7, 2003, with the exception of June 9, 2003, when the air compressor was serviced. On July 7, 2003, the AS system was deactivated due to the lack of groundwater in the AS wells. Earth Tech prepared a report entitled Monitored Natural Attenuation Progress Report, for the former Sunland Oil Refinery, Bakersfield, California (Attachment F). The report includes results of monitored natural attenuation (MNA) parameters analyses (Tables F-1 and F-2) with 'a discussion of the results and I recommendations. This MNA report and results of general minerals analysis are presented in Table 4, as requested by the RWQCB in their letter to World Oil i dated September 7, 2001. Monitoring Monitoring was performed during weekly operation of subsurface conditions and maintenance (O&M) of the HCVES and LPH removal system and during semi- annual groundwater gauging and sampling. During HCVES operation, weekly I O&M activities included measuring extraction flow rates, system total influent hydrocarbon concentrations in the vapor stream, system vacuum, processing temperatures and utility usage for electricity and supplementary natural gas. I Individual remediation wells were monitored for groundwater and product levels, hydrocarbon concentrations in the vapor stream, vacuum, and condensate/product removal activities a minimum of once a month. Vapor samples were collected I from the flare inlet header(s) for laboratory analysis once a month. From weekly data and monthly data, the system was adjusted to optimize removal of subsurface i contaminants. Based on laboratory analyses, extracted total petroleum hydrocarbon, benzene, and MTBE in soil vapor have increased from January 2003 through July 2003 i compared December 2002 and decreased from August 2003 through December to 2003. E A R T H T E C H A ~CO INTERNATIONAL LTD* COMPANY Mr. John T. Mitchell, Esq. , 4 Kern County District Attomey~s Offic_~__~e March 30, 2004 Groundwater monitoring and sampling activities were performed in March and September 2003. Figure 5 is a site map showing the groundwater monitoring well locations. The groundwater elevation data and analytical results for the two sampling events are summarized in Tables 1, 2, 3 and 4. On November 25, 2003 Earth Tech submitted a request to the CVRWQCB to discontinue the sulfate and chloride inorganic analysis in wells SE-MW-20(S), SE-MW-29(D), SE-MW-24(S) based on historical analytical data. Since 1998, the reported chloride and sulfate concentrations detected in the groundwater samples from these wells have shown a downward trend and have not exceeded the WDR levels. In addition, the long term monitoring performed by World demonstrates that the inorganic concentrations observed in the Pond Area soils have not impacted the groundwater in the area. From March 2003 to October 2003, the semi-annual groundwater monitoring data indicated that the groundwater level in wells have dropped an average of 6.3 feet. The calculated groundwater gradient ranged from 0.0074 feet/foot (0.7%) to 0.009 feet/foot to the northwest, from the Kern River. (0.9%) away Groundwater data, summarized in the 2003 Semi-Annual Groundwater Monitoring Status Reports, are presented and in Appendix C. Groundwater contour and hydrocarbon concentration maps for 2003 are also presented the 2003 Semi-Annual Groundwater Monitoring Reports. ASSESSMENT FOR 2003 In December 2002 and in July 2003, nine additional on-site remediation wells were installed at the former STF site. The installation of five triple-nested combination air sparge (AS)/vapor extraction (VE) wells (AS/VE-73 through AS/VE-76 and AS-VE-81) and four triple-nested AS wells (AS-77 through AS- 80) was performed in accordance with the Workplan for Additional Off-Site Investigation and Remedial Optimization (Workplan) dated October 31, 2002 and approved by the CVRWQCB on January 10, 2003. SCHEDULE O&M of the remediation system will continue as scheduled in 2004. The next groundwater monitoring and sampling event is scheduled for March 2004. Approval for accessing the off-site PG&E Kern Steam Plant was granted by PG&E on December 15, 2003. Therefore, the off-site investigation which includes the installation of four offsite groundwater investigation wells, and eleven dual-nested VE wells and triple-nested AS wells on property owned by PG&E will be conducted per the approved Workplan dated January 10, 2003, in March of' 2004. The CVRWQCB will be notified prior to performing the well installation activities. E A R T H ~ T 'E C H A ~"~0 INTERNATIONAL LTD. COMPANY I Mr. John T.

Extraction from the well was terminated prior to water entering the vacuum track tank. (2) Flexible PVC stingers were installed to use the existing vapor extraction system (or other vacuum source, i e.g., vacuum truck) to remove LPH from the source wells. If the vapor extraction system is used, the . LPH is extracted via air lift created by the vacuum extraction blowers and LPH accumulates in the knockout vessels during HCVES operation. If a vacuum truck is used, the LPH is extracted directly through stingers into the vacuum truck for transport and disposal off-site. I (3) Excluding LPH and water from well stinging. · (4) All liquid generated by the HCVES system was incinerated by the flare in May and October 2002, including condensate and the LPH stung from wells in May 2002. (5) The total volume of condensate generated during HCVES operations was visually estimated as 5 to 25 pement LPH i observed in the liquid generated. The LPH volume generated by the HCVES does not include LPH from well stinging.

Extraction from the well was terminated prior to water entering the vacuum truck tank. (2) Flexible PVC stingers were installed to use the existing vapor extraction system (or other vacuum source, I e.g., vacuum truck) to remove LPH from the source wells. If the vapor extraction system is used, the LPH is extracted via air lift created by the vacuum extraction blowers and LPH accumulates in the knockout vessels during HCVES operation. Ifa vacuum truck is used, the LPH is extracted directly through stingers into the vacuum truck for transport and disposal off-site. ~l (3) Excluding LPH and water from well stinging. · (4) All liquid generated by the HCVES system was incinerated by the flare in May and October 2002, including condensate and the LPH stung from wells in May 2002. (5) The total volume of condensate generated during HCVES operations was visually estimated as 5 to 25 percent LPH i observed in the liquid generated. The LPH volume generated by the HCVES does not include LPH from well stinging. (6) The total recyclable liquid removed from the site this period includes the liquid removed from the HCVES knock-out tanks, the above-ground storage tanks, stung wells, and non-hazardous purge water removed from drums. !

No.: RWQCB - Central Valley Region Mr. Brace Myers / File No. CAO 95-702 I WORK PERFORMED June 2003 -November 2003: 1. Earth Tech performed operations and maintenance- (O&M) of the high capacity vapor extraction I . system (I-ICVES) and air sparge (AS) system dttd~g this reporting period, June 1, 2003 through November 30, 2003. 2. For this reporting period, the AS system was in operation between June 1 to July 7, 2003, ~with the I exception of Jtme 9, 2003, when the ak compressor was serviced. On July 7, 2003, the AS system was deactivated due to the lack of groundwater in the AS wells. I 3. LPHs were removed from the South Tank Farm (STF) wells SE-AS/VE'47c, SE-VE-48c, SE-VE- · 49c, AS/VE-73c, AS/V'E-74c ASNE-75c, and from the former West Tank Farm (WTF) wells MW- 9R, MW-16, SE-SVE-42c and SE-SVE-43c, during this monitoring period using a vacuum track. The LPH waste was disposed of at DeMenno Kerdoon, Comptoa, California. I 4. Earth Tech monitored the groundwater levels, LPH levels, and measured ASNE remediation well hydrocarbon concenlrations and vacuum pressures on June 24 and 25, 2003, July 23 and 24, 2003, I August 18 and 19, 2003, September 23, 2003, and October 24 and 25, 2003. Each SVE well was · adjusted for extraction according to the hydrocarbon vapors measured in each well. Groundwater and LPH levels in the groundwater monitoring wells were also gauged on September 22, 2003 as part of the semi-annual monitoring program I .5. Wayne Perry, Inc. (Wayne Pen'y), purged and sampled the on- and off-site groundwater monitoring wells between September 22 and 26, 2003. For this period, approximately 1,645.4 gallons of I ground water was purged from wells. Wayne Perry also measured natural attenuation parameters and general minerals, as requested by RWQCB (RWQCB Letter dated September 7, 2001). 6. Earth Tech prepared a report entitled Monitored Natural Attenuation Progress Report, 2~ Half I 2003 for the Former Sunland Oil Refinery, Bakersfield, California (Attachment F). The report includes results of monitored natural attenuation (MNA) parameters analyses (Tables F-1 and F-2) with a discussion of the results and recommendations. This MNA report and results of general minerals analyses are presented in Table 4, as requested by the RWQCB in their letter to World Oil I dated September 7, 2001. H ~ 'r I: ¢ H INTERNATIONAL LTD. COMPANY I WORK PROPOSED FOR NEXT REPORTING PERIOD (December 2003 through May 2004) 1. Conduct groundwater well gauging, purging, and sampling in March or April 2004. ! 2. Continue O&M of the HCVES and LPH removal.system. I 3. Install additional groundwater monitoring wells down gradient of the site (PG&E property) in order to define the MTBE plume in groundwater, upon approval of an access agreement by PG&E. Install new offsite AS and VE wells and connect these wells into the existing HCVES/AS system.

Using a SolinstTM Water Level Meter and/or an oil/water interface probe, each well shall be gauged for depth to groundwater, depth to floating product, if present, and total well depth. Gauging devices shall be decontaminated between each well using a triple-rinse method of tap water with non-phosphate detergent, tap water and then deiomzed water. Wells shall be gauged in expected sampling order of increasing hydrocarbon concentrations to deter potential cross-contamination. The sampling sequence will be based on the analytical results obtained during the previous sampling event. Wells showing petroleum hydrocarbon sheen during gauging or purging will be sampled only if no sheen was observed following purging and recovery. Wells containing floating product will not be sampled; however, the thickness of floating product in these wells shall be measured and recorded, and then the free product removed by bailing or vacuum truck. Groundwater Purging and Samolin~ Off-Site Monitoring Wells During the semi-annual groundwater sampling, off-site monitoring wells (SE-MW-51, GlVIX- MW-60, GMX-MW-61 and GMX-MW-62S) that were constructed with more than 20 feet of submerged well screen, shall be purged and sampled using low-flow (micro-purge) methods as long as the water column was greater than 20 feet. The purpose of the micro-purge technique was to obtain relatively depth-discrete samples to assess the vertical distribution of hydrocarbon constituent concentrations in wells completed with longer screen intervals. The micro-purge, depth-discrete samples shall be collected using a 2-inch diameter Grudfos Rediflow submersible pump, or equal, at two vertical depth intervals at each well. The pump shall be initially lowered to a depth of approximately 5 feet below the measured groundwater surface to purge and collect the first sample. The second sample shall be collected in the lower portion of the well-screen interval at a depth of approximately 100 feet bgs. Purging shall be initiated and maintained at the lowest rate attainable by the pump (normally 100, but up to 300 milliliters per minute) to vertical within the well. Water levels shall be monitored during purging to mixing confirm that the draw down during purging is negligible. Purging shall continue until a minimum of two discharge-line volumes are removed and the water quality parameters (pH, conductivity, turbidity, and temperature) stabilize. Following purging at each specific depth, groundwater samples shall be collected from the discharge line of the pump and Iraasferred directly into sample containers provided by the laboratory. The containers shall be capped with TeflonTM septa, labeled, and placed on ice for transport to American Analytics, a State-certified laboratory located in Chatsworth, California. The pump shall be decontaminated between samples with a non-phosphate detergent wash-water solution that is cycled through the pump followed with a &ionized water rinse. New disposable tubing shall be used on each subsequent well. On-Site Monitoring Wells For the on-site monitoring wells, at least three casing volumes of groundwater shall be removed from each well using a PVC bailer or submersible pump. During purging, water parameters including pH, temperature, conductivity, and turbidity shall be monitored to calculate stabilization within 10 percent of each parameter and ensure that groundwater representative of the aquifer enters the well. The bailer shall be decontaminated between each well using a triple- rinse method of tap water and non-phosphate detergent, tap water and then ionized water. The pump shall be decontaminated by cycling the wash-water through the pump followed with a deionized water rinse. Wells shall also be purged in expected order of increasing hydrocarbon concentration to prevent cross-contamination. After purging, wells shall be allowed to recharge to at least 80 percent of their original capacity prior to sampling. Groundwater samples shall be collected using a polyethylene disposable bailer attached to a new nylon cord. Samples shall be transferred to containers provided by the laboratory appropriate to the analysis performecL The containers shall 'be capped with TeflonTM septa, labeled and placed on ice for transport to New (nylon c~d, bailer, etc.) shall be used on each American Analytics. sarnpling equipment subsequent well to prevent cross-contamination. Quality Assurance / Quality Control (OA/OC) Saml)les Quality control samples submitted to the laboratory shall include the following: · Duplicated groundwater samples, · Laboratory-prepared trip blanks. One trip blank shall be kept in the sample cooler and submitted with each set of g~:oundwater samples to the laboratory. Chain-of Custody protocol shall be executed in the field immediately following sample collection to accompany the samples to the laboratory. Liquid-Phase Hydrocarbon (LPH) Removal LPH shall be removed from wells using one of the following methods: · Flexible PVC stingers that extract the LPH via airlift created by the vacuum extraction blower, · Dedicated submersible pumps, · Vacuum ~uck service. Waste Disposal Purge water generated during this momtoring event will be stored at the site in labeled steel, 55- gallon drums and will be transported under a bill..of-ladmg to DeMenno/Kerdoon in Compton, by Asbury Environmental Services. Removed product and condensate generated from the I-ICVES will also be stored on site in 55- gallon drams, pending transportation and disposal by Asbury Environmental Services.

Introduction Earth Tech, on behalf of World Oil Corp. (World Oil), has evaluated ~the results of monitored natural attenuation (MNA) parameters collected in the second half of 2003 and prepared this report for the former Sunland Oil Re£mery (the Site), at 2152 Coffee Road, Bakersfield, California (Figure 1). This study was prepared as requested by the RWQCB in their correspondence to World Oil dated September 7, 2001. The IvlNA sampling began with the second half 2001 sampling event and was continued through the second half 2003 sampling event. Wells for monitoring were selected based upon their locations relative to the groundwater plume as Upgradient wells, source area (primarily the former South Tank Farm [STF]) wells, downgradient wells and cross gradient wells (shown in Figure 2 and Tables F-l). These wells were monitored for general groundwater qualities and geochemical conditions of the aquifer. The monitoring parameters include oxidation-reduction potential (ORP), dissolved oxygen (DO) concentration, pH, temperature, specific electrical conductivity, sulfate, nitrate, ferrous iron, methane and alkalinity. This report evaluates the MNA data, which are presented in Tables F-1 and F-2, and provides recommendations. F-2. Monitored Natural Attenuation.(1VINA) When a petroleum hydrocarbon is released into a subsurface environment, indigenous microorganisms begin to aerobically biodegrade presence the contaminants in the of sufficient oxygen. However} as the microorganisms degrade the hydrocarbons, the available oxygen is rapidly utilized and the contaminated area evolves into an anaerobic (oxygen deficit) environment. The hydrocarbons continue to biodegrade anaerobically, although the rate of degradation slows down. The transition from aerobic to anaerobic environment during the biodegradation of COCs involves a series of oxidation-reduction reactions and the process heavily depends upon the availability oftemfinal electron acccptors CI'EAs). TEAs must be present in sufficient quantity to accept electrons released from hydrocarbons (i.e., electron donors) as they degrade. Important TEAs in order from most to least preferred reactions, include (after oxygen): nitrate (NO'3), manganese 0Vm+4), ferric iron (Fe3~), sulfate (SO4'2), and carbon dioxide (CO2). Important metabolic by-products, which are produced during the electron transfer process for biodegradation of the Site COCs, include manganese (Mn+2), ferrous iron (Fe+2), methane (CH4), and alkalinity (in lieu of CO2). To demonstrate the availability of TEAs production by-products, and of metabolic groundwater samples were collected at selected wells for analyses of DO, ORP, nitrate, ferrous iron, sulfate, methane and alkalinity. The data will be used to verify the biological activity at the Site and evaluate the of MNA. progress I i Baseline Study of Monitored Natural Attenuation Parameters The Former Sunland Oil Refinery Second Half2003 · I I F-3 MNA Sampling Results -1 MNA sampling events have been conducted biannually since October 2001. MNA parameters I were collected, at upgradient wells MW-101L SE-MW-22, and SE-MW-25; at source area wells SE-MW-gR and SE-MW-23S; at cross gradient wells SE-MW-20S, SE-MW-21, SE-MW-26, SE- I MW-27 and SE-MW-62S; and at the downgradient wells SE-MW-51, GMX-MW-60, GMX-MX- 61, TSG-MW-67A/B/C. Note that wells SE-MW-9lL GMX-MW-62S, SE-MW-51 and TSG- ' MW-67A were not sampled for MNA parameters after March 2002 because free product was i present at wells SE-MW-9R and wells GMX-MW-62S, SE-MW-51 and TSG-MW-67A were dry. The results for the September/October 2003 MNA sampling event are presented in Table F-1 and the results of all MNA sampling events are summarized in Table F-2. The October 2002 I event served as the baseline event since air operation and/or air testing monitoring sparge sparge was performed from October 2001 through March 2002. ~ As discussed above, the preferred TEA is oxygen under aerobic conditions and as such, dissolved ' · oxygen should be depleted in the areas containing the highest hydrocarbon concentrations. As the oxygen is utilized in the source areas, nitrate, ferric iron, sulfate and CO2 will be consumed as I TEAs by indigenous microorganisms in sequence t° sustain the biological activity. Metabolic by- product indicators such as ferrous iron and methane are produced in the aquifer as femc iron and CO2 are utilized. Carbon dioxide is also the end product of the hydrocarbon biodegradation. The I increase of alkalinity (in lieu of CO2) is also expected at the area containing the highest hydrocarbon concentrations. I Dissolved Oxygen (DO) The DO concentrations are generally lower in the source area, where Site COCs are present. Based on the September/October 2003 data, the pre-purged DO measurement is 0.5 mg/L at I well SE-MW-23D and is 3.4 mg/L at well SE-MW-20S. The pre-purged DO source concentrations at the upgradient, cross gradient and downgradient wells ranged from 10.0 mg/L to 15.5 mg/L. I Oxidation-Reduction Potential (ORP) I The groundwater ORP is an indicator to the overall redox conditions of the aquifer and the changes of ORP in groundwater are usually mediated by biological activity. In general, a positive ORP greater than 50reV is indicative of the presence of dissolved oxygen and would potentially I support aerobic microbial activity. A negative ORP 'less than -50mV is indicative of the lack of DO and' hence would support anoxic or anaerobic microbial activity. The ORP levels would be lower in areas that have exhibited the highest Site COC concentrations due to the utilization of i oxygen for ~biodegradation. The second half 2003 ORP data showed that OR.Ps were less than -50mV at wells SE-MW-23D, SE-MW-20S and TSG-MW-67B. The downgradient well TSG-MW-67C also had ORP I The DO and ORP data wells SE-MW-23D and SE-MW-20S in measurement below 0. at were agreement and were expected because of the presence of Site COCs at those wells. However, negative OR.Ps at TSG-MW-67B/C did not agree with DOs, which suggest the oxidative Iconditions at TSG-MW-67B/C. TEPH (C6-C14, 0.21 mg/L), toluene (0.0011 mg/L), total xylene (0.0034 rog/L) and MTBE (0.0031 rog/L) were detected at TSG-MW-67B and no COCs were detected at TSG-MW-67C. Additionally, metabolic by-products, ferrous iron and methane, were I ,I Baseline Study of Monitored Natural Attenuation Parameters The Former Sunland Oil Refinery Second Half 2003 not detected at TSG-MW-67B/C. Data suggested that Site COCs has low or no impact on TSG- MW-67B/C and the anaerobic biological activity is negligible. Nitrate (NOr~) Nitrate serves as .a TEA through the processes of denitrification and nitrate reduction. The depletion of nitrate occurs, as aquifer conditions become more oxygen deficient. Nitrate was not detected at SE-MW-23S/D in September/October 2003. The historical nitrate data also indicated that nitrate has not been detected at wells SE-MW-9R, SE-MW-238 and GMX-MW-60. The non-detections of nitrate revealed that nitrate has apparently been fully utilized within the source area, but there is sufficient nitrate upgradient and doWngradient of the nutrients for continued degradation of the contaminants and to source area to supply necessary' continue to serve as a TEA. Ferric (Fe+~) and Ferrous (Fe+2). Iron Ferric iron (Fe.3) is the next most preferred TEA. Available Fe+3 on soil surface can serve as a TEA and be reduced to soluble Fe+2. The utilization ofFe+3 is generated resulting in the presence of Fe+2 within the area exhibiting the highest hydrocarbon concentrations. In September/October 2003, wells SE-MW-23S/D exhibited Fe+2 concentrations and Fe+2 was not detected at all upgradient, cross gradient and downgradient wells. The analytical results indicated that a significant iron reduction zone is present in the source area. Sulfate (SOl~) Sulfate is the next most preferred TEA and as such, sulfate concentrations should also be depleted or low within the area exhibiting the highest hydrocarbon concentrations. The analytical results reduction is evident in the area. Well SE- show significant sulfate zone not necessarily source MW-23S contains high sulfate concentration (590 mg/L) compared to the sulfate concentrations. at the upgradient wells MW-10R (15 rog/L) and SE-MW-25 (21 rog/L). The sulfate data suggest {:hat sulfate-reduction bacteria may be inhibited or the source of sulfate may be present at the Site that contributes sulfate into aquifer. Methane (CH~) Mcthanogenesis is most likely to occur in a source area due to the extremely reduced environment and the presence of a high organic carbon content. Methane is the ultimate reductive metabolic product of carbon dioxide and the detection of methane in groundwater is indicative of very low oxidation-reduction potential. As expected, the elevated methane concentrations were detected at wells SW-MW-23S/D in the source area and well SE-MW-20S where reduced conditions were evident. Alkalinity (COz) Alkalinity can be used as a valuable indicator of microbial activity. It reflects the buffering capacity of groundwater and is most influenced by the CO~ content that originates from the dissolution of carbonates in the aquifer, atmospheric CO~, and the respiration of microorganisms. As the sequential TEAs are utilized, CO2 is the last preferred TEA, but it is also produced at each metabolic step and is the end product during contaminant degradation. Therefore, alkalinity can produce equivocal results (i.e., it is being generated and depleted simultaneously). The alkalinity Baseline Study of Monitored Natural Attenuation Parameters The Former Sunland Oil Refinery Second Half2003 varies and does not necessarily reflect a pattern that would suggest the presence of a CO2 reduction zone. However, elevated alkalinity is generally observed in the area containing high cOncentrations of biodegradable hydrocarbons. Alkalinity data were presented in Table 4 and were collected in September/October 2003 at upgradient wells MW-10R and SE-MW-25, source wells SE-MW-23S/D, and downgradient wells GMX-MW-67B/C. The results revealed that the highest alkalinity (200 rog/L) was detected at SE-MW-23D. However, alkalinity was not detected at SE-MW-23S which contained 2.4 mg/L methane. Thus, alkalinity results have not suggested the presence of a CO2 reduction zone, but have suggested the production of high CO2 concentrations via the biodegradation of hydrocarbons in the source area. F4 Recommendations Based upon the observed data, natural attenuation of petroleum hydrocarbons is occurring in the subsurface at the Former Sunland Refinery. We recommend the continued monitoring of the geochemical indicator parameters (i.e., pH, temperature, specific conductivity, ORP, DO, nitrate, ferrous iron, sulfate, methane and alkalinity) to track and further evaluate the ongoing natural attenuation processes.

(World), Earth Tech, Inc. (Earth Tech) respectfully requests a minor modification to the current sampling strategy for the Sunland Oil Refinery (Site). Currently, groundwater monitoring wells SE-MW-20(S), SE-MW-24(S), and SE-MW-29(D), T e I e p h o n e associated with the Pond Area, are analyzed for sulfate and chloride on a semi-annual bases, to demonstrate that the past usage of the Ponds have not impacted groundwater. We would like 562.95 ~. ~ o o o to request that sampling for sulfate and chloride at these wells be terminated, based on historical data at these locations. A summary of the Pond Area background, and our rationale Facsimile for discontinuing analyses for sulfate and chloride at these wells is provided below. Bacl~round 562.95 ~ · 2 ~ o o The Pond Area formerly (formerly or currently) contained four wastewater ponds, designated Pond 1 through Pond 4, which accepted refinery wastewater generated from petroleum processing units and non-processing units such as cooling towers (SECOR, 1997). The wastewater ponds are located west of the Coffee Road overpass, south of the ATSF railroad tracks, and east of the Pacific Gas and Electric (PG&E) easement. The refinery wastewaters were discharged in a concrete-lined Pond (Pond 1), which subsequently flowed into the remaining 3 unlined Ponds. Sunland suspended their refining operations on iMarch 30, 1995. In February and October 1997, SECOR conducted a subsurface investigation beneath the ponds, and based on the results, the RWQCB indicated that no further action was required in the wastewater pond area (RWQCB letter dated February 10, 1998). However, at the time, the RWQCB was concerned about the elevated inorganic concentrations detected in soil samples collected from beneath the pond areas, and the potential for these inorganic compounds to migrate to groundwater. Since 1998 World has complied with the RWQCB directive to conduct groundwater monitoring and sampling of select wells in the Pond Area for chloride and sulfate. Groundwater Monitoring (1996-present) From September 10, 1996, to September 2003, World conducted 12 semi-annual sampling events on existing monitoring wells. Two down-gradient Pond Area monitoring wells SE- MW-20(S) and SE-MW-29(D), and a west tank farm (WTF) monitoring well SE-MW-24(S) were monitored for chloride and sulfate concentrations as required by.the Central Valley Regional Water Quality Control Board (RWQCB) Order No. 90-86. The chloride concentrations in these wells decreased from 220 mg/l in September 1996 to 56 rog/l, in September 2003: The sulfate concentrations have increased in these same 3 wells over the last sampling events from October 2002 to September 2003, although concentrations have E A R T H T E C A ~'~ INTERN,AT/O/VA/LTD. ~OMPAIVY Mr. Bruce Meyers Page 2 Central Valley Regional Water Quali~y Control Board November 25, 2003 remained substantially lower than the Waste Discharge Requirements (WDR) of 200 mg/1 and 100 mg/l, respectively, since 1998 (Table 1). Also, based on Title 22 of the California Code of Regulations, Chapter 15, Article 16, Secondary Drinking Water Standards (SDWS) in Section 64449, Secondary Maximum Contaminant levels (MCL)-Table 64449-B, the chloride and sulfate concentrations detected in the 3 monitoring wells were below the MCL of 250 mg/1 for each analyte. Conclusions In summary, based on SECOR's Pond Closure Report (1997) and historical groundwater ~monitoring results, Earth Tech concludes the following: · The 1997 wastewater pond closure activities conducted by SECOR were adequately completed and no further action in the Pond Area was granted to World Oil by the RWQCB. · Since 1998, World Oil has performed groundwater monitoring to demonstrate that the inorganic constituents from the Pond Area have not migrated to groundwater, groundwater concentrations in key monitoring wells have remained below the Waste Discharge Requirement (WDR) levels outlined in Order 90-86. · In the last 5 years, the reported chloride and sulfate concentrations detected in the groundwater samples have shown a downward trend and have not exceeded the WDR levels. Based on the above, Earth Tech recommends that the chloride and sulfate inorganic groundwater analysis at wells SE-MW-20(S), SE-MW-29(D), SE-MW-24(S) be discontinued since the observed concentrations are currently, and have historically been below the WDRs. In addition, the long term monitoring performed by World demonstrates that the inorganic concentrations observed in the Pond Area soils have not impacted the groundwater in the area.
