Home My WebLink AboutANNUAL REMEDITION SUMMARYREP. 4/1/1999 /HIc't'tl(dll't~llgl/ March 30, 1999 John T. Mitchell, Esq. Deputy District Attorney Kern County District Attorney's Office Consumer and Environmental Protection Unit 1215 Truxtun Avenue Bakersfield, California, 93301 RE: ANNUAL REMEDIATION SUMMARY REPORT - SUNLAND OIL REFINERY 2152 Coffee Road, Bakersfield, California Final Judgement Pursuant to Stipulation (KCSC No. 228 399-RA) Cleanup and Abatement Order No. 95-702 Dear Mr. Mitchell: Tills annual~emediation summary report was (SECOR) on behalf of World Oil Corp. (WORLD) for the Sunland Oil Refinery site (Sunland) in Bakersfield, California (Figures 1 and 2). This report summarizes the remediation data and efforts for the calendar year 1998. INTRODUCTION This report on WORLD's remedial activities in compliance with the California Regional Water Quality Control Board - Central Valley Region's (CRWQCB) Cleanup and Abatement Order (CAO) No. 95-702 dated April 27, 1995, has been prepared pursuant to the "Final Judgement Pursuant to Stipulation" (KCSC No. 228 399-RA). The CAO directs Sunland Refining Corporation to address petroleum hydrocarbon impacted soil and groundwater documented at the subject site during previous soil and groundwater investigations. Item 8 of the Final Judgement requires the submittal of an annual summary regarding the status of site remediation efforts to contain and cleanup groundwater and soil contamination under CAO No. 95-702. The Sunland facility is divided into three main areas: the former West Tank Farm (Figure 3), the refinery plant/former South Tank Farm (Figure 4), and the existing North Tank Farm (Figure 5). John T. Mitchell, Esq. Kern County District Attorney's Office March 30, 1999 Page 2 E~C~IVESUMM~Y Based on the progress of 1998 remedial activities outlined above, the following summary and conclusions are presented: · Remedial Activity - During 1998, approximately 175,581 pounds of total hydrocarbon mass have been removed from the subsurface. The two soil remediation systems located at both the former West and South Tank Farms were removed and replaced by a single high-capacity extraction system (HES). The HES was started on September 16, 1998. Hydrocarbon mass removed from the subsurface utilizing the HES is approximately 31,909 pounds through the end of 1998. · Off-site Assessment Activities - Assessment to characterize the extent of contaminants in groundwater, as required in CAO 95-702, has been completed in all directions including the down-gradient direction to the nOrthwest. On August 27, 1998, SECOR installed one downgradient groundwater monitoring well at PG&E's Kern Steam Plant. Data and analytical results from the downgradient well installation are transmitted to the CRWQCB in a well completion summary report and semi-annual monitoring report in compliance with the Corrective Action Plan, dated August 30, 1996. R'EMEDIAL ACTIVITY FOR 1998 Soil and Groundwater Remediation Soil Vapor Extraction (SVE) and Air Sparging (AS) remediation systems were operated at the South Tank Farm (STF) until June 19, 1998 and at the West Tank Farm (WTF) until July 30, 1998. These systems were removed during installation of the HES in preparation for the startup of the HES. The automatic liquid-phase hydrocarbon (LPH) recovery system was monitored every other month during the first half of 1998. Due to reduced product levels in the wells and rising groundwater table elevation, the LPH was monitored on a quarterly basis for the second half of 1998. During the year, the SVES/AS and HES systems removed a combined total of 175,581 pounds of hydrocarbons. Through the end of 1998, soil vapor extraction is responsible for removing a cumulative total of 387,146 pounds of hydrocarbons from subsurface soil and groundwater since remedial operations began in March 22, 1996 (Figure 6). Vapor extraction and air sparging operations are summarized in Appendix A. Through the end of 1998, approximately 525 gallons of LPH have been removed by a combination of hand bailing and pumping (176 gallons in calendar year 1998). LPH recovery operations are summarized in quarterly tables presented in Appendix B. SECOR John T. Mitchell, Esq. Kern County District Attorney's Office March 30, 1999 Page 3 Monitoring Monitoring of subsurface conditions during remedial activities has been performed through weekly operation and maintenance (O&M) of SVE/AS, LPH, and HES systems and through semi-annual groundwater gauging and sampling. During SVES and HES operation, weekly O&M activities entail measuring system parameters including extraction flow rates, system vacuum, processing temperatures, and utility usage for electricity and supplementary natural gas. Hydrocarbon concentrations in the vapor stream are measured for the total system and from individual extraction wells. From the weekly data, efficiency of the system is calculated, operation of the system is optimized, and the mass of volatile hydrocarbons removed from the subsurface is calculated. Operational data is summarized in quarterly reports (Appendix A), and the cumulative mass of extracted hydrocarbons is plotted (Figure 6). Based on laboratory analyses of extracted total petroleum hydrocarbon (TPH) and benzene, hydrocarbon concentrations in vapor have remained relatively constant over the course of the year, indicating that the mitigation process is effective and that sufficient hydrocarbon remains in the subsurface to operate the systems at full capacity. Semi-annual groundwater monitoring has measured a gradual increase in groundwater elevations (average of 4 to 8 feet) from first quarter 1998 through third quarter 1998 (Table 1). Measurements obtained by SECOR during the August 1998 site groundwater monitoring event showed the depths to groundwater beneath the site ranging from approximately 53 to 86 feet bgs. The calculated groundwater gradient was approximately 0.0117 feet/foot (1.17%) to the northwest, away from the Kern River. Groundwater data is summarized in the 1998 Semi-Annual Monitoring and Status Reports presented in Appendix C. Groundwater contour and hydrocarbon concentration maps for 1998 are presented in Appendix D. tIES Remediation Installation From June through September 1998, Unit Construction Company conducted the installation of a high capacity, emission control device (flare) and associated piping. The HES incorporates soil vapor extraction remediation activities for both the West and South Tank Farm areas. Subsurface piping connected to a John Zink Company flare (situated on the former South Tank Farm) conveys soil vapors from existing wellheads. Thirteen (13) wells located on the South Tank Farm and twelve (12) wells located on the West Tank Farm are connected to the HES. A common 6-inch diameter underground conveyance line carries vapors from the West ~'ank Farm manifold area to the HES compound. SECOR John T. Mitchell, Esq. Kern County District Attorney's Office March 30, 1999 Page 4 OFF-SITE ASSESSMENT FOR 1998 Compliance with the CAO for the Sunland Refinery includes defining "the lateral and vertical extent of contaminants in groundwater" (Item 3). The extent of hydrocarbon impacted groundwater had been completed in every direction except in the down-gradient direction to the northwest. In 1997 and early 1998, WORLD completed negotiations to obtain access to the Pacific Gas and Electric Company's (PG&E) Kern Steam Plant to initiate off-site assessment in the northwest downgradient direction. On August 27, 1998, sEcoR installed one downgradient groundwater monitoring well (SE-MW- 51) to a depth of 105 feet below ground surface on PG&E's facility (Figure 2). No detectable TPHg, TPHd or BTEX concentrations were detected in the soil samples. MTBE was identified in soil sample SE-MW-95 at a concentration of 0.2 mg/kg. Groundwater analytical results revealed that total petroleum hydrocarbons were present at 1.1 mg/L but did not match a gasoline pattern. MTBE was identified in groundwater Sample SE-MW-5.1 at a concentration of 3.89 mg/L. Data are supplied to the CRWQCB as part of the semi-annual groundwater monitoring report and off-site monitoring well installation report.

(WORLD), has revised the Overview for Tank Cleaning portion of the protocols for the cleaning of three aboveground storage tanks (ASTs) 74001, 74002, and 15056 at Sunland Refinery's North Tank Farm. The original protocol submittal was dated June 29, 1998. The Ambient Air Monitoring section was revised to include monitoring during loading and degassing operations, and the AST Ventilation/Degassing section was modified to include notification and permitting requirements for degassing activities. I trust these modifications meet your requirements. SECOR will notify the district 48 hours before cleaning operations are initiated. Thank you for your prompt attention to this matter. If you have any questions or concerns, please contact either of the undersigned at (805) 230-1266. Sincerely, SECOR International Incorporated Karl D. Bowers, R.G.

(WORLD) and SECOR International, Incorporated (SECOR) have prepared the following protocols to remove fluids, sediments, and/or sludge and clean three above ground storage tanks (ASTs) within the North Tank Farm (NTF) facility, located adjacent to the Sunland Refinery. Specifically, the following tanks will be emptied and cleaned: Tank Number Contents Tank Size 74001 Sediment/Sludge 74,000 barrels 74002 Water 74,000 barrels 15056 Former Diesel 15,000 barrels Vapor Emi.qsion Controls Emissions controls are not anticipated during AST cleaning activities, since the tanks involved most recently held materials with Total Vapor Pressure (TVP) less than 1.5 pounds per square inch (psi). To prevent the potential for exceeding the lower explosive limit (LEL) and/or nuisance vapors, ambient air will be monitored for vapors exceeding 20 percent of LEL. Carbon canisters for control of loading emissions from the vacuum trucks will be on site and available for connection to the exhaust vents. Ambient Air Monitoring SECOR personnel will conduct ambient hydrocarbon monitoring using a Lower Explosive Limit (LEL) meter during loading and degassing operations. The monitoring will be conducted downwind of the vacuum truck vent. If monitoring detects 20 percent or greater of the LEL, loading operations will be shut down and the fire department and District will be notified. Personnel conducting LEL monitoring will also perform olfactory monitoring for odors which might potentially cause a nuisance. Any detected nuisance odors will be abated by sealing any vapor leaks and replacing spent carbon. AST Number 74001 - Sediment/Sludge Removal The liquid contents of AST 74001 were previously removed. The tank bottom (sediment, sludge, and residual liquid) will be removed with a Supervac and transferred to on site vac-bins. Sludge contents of AST 74001 were previously sampled for characterization and determined to be non-hazardous. Solids will be allowed to settle out and water will be removed with vacuum trucks and transferred to on site Baker tanks for temporary storage or directly off site for disposal. Solids and liquids will be sampled and characterized for disposal. AST Number 74002 - Liquid and Sediment/Sludge Removal AST 74002 contains approximately 630,000 gallons of water generated from former gravity separation from hydrocarbons and consolidated in 74002. Water will be treated using a Transportable Treatment Unit (TTU) designed and operated by Envent Corporation (Envent), The TTU is operated under Permit-by-Rule under Department of Toxic Substance Control (DTSC) and Environmental Protection 1 of 3 Overview for AST Cleaning - No. 1 Sunland Refining Corporation North Tank Farm Authority (EPA) authorizations, and is permitted with the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD). The treatment system consists of a poly surge tank, generator, air compressor, filter system, water conditioner, stripper, and an oxidizer. Treated water will be temporarily stored in a clean AST (AST No. 15055) on the tank farm or in Baker tanks before discharge. Following treatment of the majority of the water, the oily water from top of the water column in AST 74002 will be removed to vacuum trucks for shipment to the Las Palmas facility for recycling. Treated water in AST 15055 or the Baker Tank will be transported by truck to a pre-approved sewer discharge location. Discharge will be performed in accordance with the Industrial Wastewater Discharge Permit obtained from the Bakersfield Public Works Department, Wastewater Division. Treated water will be tested periodically to assure compliance with the required discharge limits in the permit. AST Number 15056 - Sediment/Sludge Removal The liquid contents of AST 15056 were previously removed. The tank bottom (residual sediment/sludge and liquid) will be removed with a Supervac and transferred to on site vac-bins. Sludge contents of AST 15056 were previously sampled for characterization and will be transported to Las Palmas for recycling. AST VentilationfDegassing and Conf'med Space Entry Permitting The District does not have a rule for ventilating and cleaning ASTs, therefore, a variance or emission controlled degassing may be required. World will be prepared to degas the ASTs with emission controls before allowing personnel to enter the ASTs for cleaning. If initial monitoring detects 20 percent or greater of the LEL, cleaning operations will be shut down, the fire department and District will be notified, and degassing of the AST will be arranged. If degassing with vapor controls is required, a company permitted by the SJVUAPCD will conduct degassing operations. Degassing with blowers to a thermal oxidizer or internal combustion engine will be used to control nuisance odors and reduce vapor concentrations to 10 percent LEL or less before ventilating to ambient air and initiating cleaning activities. An AST with vapor concentrations greater than 10 percent LEL is a confined space with hazardous atmosphere and requires'a permit for entry and the hazard eliminated (29 CFR 1910.146). Paragraph (c)(5)(i) of 29 CFR 1910.146 covers permit space entry where it can be demonstrated that forced air ventilation alone will control all hazards in the space. Alternate procedures specified in paragraph (c)(5)(ii) of this section for entering a tank may be used where paragraph (c)(5)(i) is not applicable. AST Cleaning Activities AST cleaning will be initiated following the removal of residual liquid, excess sediment/sludge, and high vapor concentrations (> 10% LEL) from each of the three tanks. AST cleaning will entail removing residual sludge/liquid from the bottoms of the tanks. Residual sludge and sediments will be moved out of the tanks using high-pressure water and squeegees. Residual liquids will be removed with vacuum trucks and transferred to Baker tanks for temporary on-site storage, sampling, and characterization. Residual sludge and sediments will be transferred to, lined bins, for temporary on-site 2 of 3 Overview for AST Cleaning 1 Sunland Refining Corporation North Tank Farm storage, sampling, and characterization. Minimizing the generation of excess residual liquids through the washing of ASTs, Vacuum trucks, and Baker tanks is essential. Prior to the removal of the waste materials from the site, the material will be sampled and characterized for waste disposal under appropriate manifest within 90-days of removal from the AST.

These trends can then be correlated with dissolved-phase hydrocarbon trends in these three wells allowing a comparison to be made. When sufficient data are collected, the Student's T-test for statistical comparison, will be utilized to evaluate differences of specified parameters (Cl' and SOn) in groundwater samples between the background control well (SE-MW-24) and the two downgradient wells (SE-MW-20 and SE-MW-29). The Student's T-test is a statistical calculation recommended in 40 CFR 265.93(b) and in the EPA's document entitled User Documentation for A Ground Water Information Tracking System with Statistical Analysis Capability. A minimum of four groundwater sampling events from each well is necessary to perform a statistical comparison. In general the sample should be of normal distribution and free of outliers (i.e. anomalous data). A calculated t-statistic (test statistic) is compared from the means and variance between the control well and each downgradient well and compared to the tabulated t-statistic. If the comparison for the downgradient shows a significant change, the well will be re-sampled and split samples collected for a qualitative check. Four sampling events of the three aforementioned wells will be performed and statistical calculations completed. As subsequent sampling events are performed, the analytical data from each well will be incorporated into the statistical comparison. Based on the results of the statistical analysis, recommendations will be made accordingly regarding the potential effects of chlorides and sulfates.

SUBJECT: REQUEST FOR BIANNUAL MONITORING AND ADDITIONAL MONITORING FOR CHLORIDES AND SULFA TES, SUNLAND REFINING CORPORA TION, BAKERSFIELD, KERN COUNTY I have reviewed the subject document along with historical monitoring reports pertaining to the subject facility'. The document was dated 15 April 1998 and prepared by SECOR International, Inc. (SECOR). The following is an evaluation of thc request to monitor groundwater on a biannual basis rather than the current quarterly basis, and an evaluation of the proposal to sample two downgradient monitoring wells for chlorides and sulfates. INTRODUCTION Sunland Refining Corporation occupies approximately 200 acres of land adjacent to the Kern River channel in the northwestem portion of the City of Bakersfield. The site consisted of three tank farms (West, North and South Tank Farms) that contained, before decommissioning activities, approximately 40 aboveground tanks. The South Tank Farm contains the main refinery facilities (now undergoing decommissioning), which included crude oil processing towers and a catalytic reformer unit. Cleanup of soils/groundwater is on a time schedule regulated by Cleanup and Abatement Order No. 95-702. Currently two Paragon ET-250's soil vapor extraction systems and two air sparging systems are operational at the site, located at both the West and South Tank Farm areas. To date, the soil vapor extraction systems have removed approximately 211,565 pounds of hydrocarbons from subsurface soil and groundwater. In addition, a free product removal system is operational at the former West Tank Farm. Approximately 347 gallons of liquid phase hydrocarbons have been removed to date. REQUEST FOR BIANNUAL SAMPLING The latest quarterly monitoring report represents the ninth submitted since the first quarter 1996. A request to change the monitoring frequency to a biannual event was first proposed to staff in a doctunent dated 14 October 1997. At that time the request was not approved due to the threat of a wet winter possibly raising the groundwater level and remobilizing petroleum constituents trapped within the vadose zone soil matrix. SECOR was requested to sample for two additional quarters before the request would again be considered. Since the fourth quarter 1997, groundwater levels rose approximately one to three feet, however, contaminant concentrations actually declined in all wells except SE-MW-23, which is an interior monitoring well within the former South Tank Farm. Given this information, and REQUEST FOR BIANNUAL GROUNDWATER MONITORINO 2 SUNLAND REFINING CORP. BAKERSFIELD, KERN COUNTY considering the current success of the air sparging/soil vapor extraction system, changing the frequency of monitoring from qu.arterly to biannual is acceptable. REQUEST TO SAMPLE MONITORING WELLS FOR SALT LOADING DA TA Board staff provided oversight on the decommissioning activities of four wastewater disposal ponds located on the West Tank Farm and provided comments on closure activities by correspondence dated 10 February 1998. Since subsurface soil samples from beneath the footprints of the disposal ponds showed elevated concentrations of chlorides and sulfates, Sunland was asked to address the relevancy of this to overall refinery closure activities. To address this issue, SECOR proposes to sample two downgradient (1 shallow, SE-MW-20(S); 1 deep, SE-VE/MW-29(D)) monitoring wells for these constituents and incorporate this into their sampling and analysis plan. When enough groundwater data has been collected to establish a trend for chlorides and sulfates, a determination will be provided concerning the relevancy of this data to overall refinery closure activities. CONCLUSION 1. The request to switch from quarterly to biannual monitoring at the Sunland Refinery is acceptable. 2. The proposal to sample two downgradient monitoring wells for data on the effects of chlorides and sulfates on overall refinery closure activities is appropriate, however, additional information on how this data is to be analyzed (statistical analysis, correlation with previous data, threat to groundwater vs. hydrocarbons) should be provided. Our mission is to preserve and enhance the quality of California's water resources, and ensure their proper a/location and e.~cient use for the benefit of present and future generations. · - II .' . ~ ~ "--. . %, ~,,~; . ~ mmmo ~/ ..... ::::::::::::::::::::::: :=::::::::::~.~: ~e: ' . ~ ~.~ ...... ~ .. ~===~=~..~ o ' .... ~ · · ' ....... ::==~ ........ ~' ,::'~,~ ~ o .." . o ~: ~.~:=W~b · ~ ..~.~.....~.b~:.~'..... :~.~.~-,~ ~; ~ ~, ~ .... ~... .-,~o,~ :, , ... ~. ,., ................. . :,..~ . ~;~ ./~ ;: --:: ,.~....-/~,,., · ' ~] ~ar~ ~ : ·: ~...- ..... : .... . ,~ .. ~:~ ,~ . ~ ................... ~ ~ ~: . ~=~ , ---~,~:~ ~(.' ~. .' :.~ /' ,., .... o ~~~' ., . .o .. . ~ ?:~:. :::qi(~:.... -. ......... 2~~ ~ ;~o .~0.~. ~, .... ,," , ..'-'...' .- .............. ... ,~o-- ~ ~ ~, ,,7~ '~k 28 , . . . ~7~- ~=o ....... .,i' . q"-'. ~P ........ .." ~ ,, ~ · . ~ ~ ~. -- , '/ · -..'~-3~. .'

(SECOR) is providing provisions to avoid sample dilution during groundwater sampling, a rationale for monitoring well placement in the Workplan, dated March 12, 1998, and a time schedule, as requested. Groundwater Sampling Groundwater samples collected from the proposed monitoring well will follow the procedures outlined in the SECOR Workplan dated March 12, 1998. The sample will be collected from the upper 18-inches of the water column. The groundwater samples collected will be submitted to a California State certified laboratory for analyses under chain-of-custody protocol. The samples will be analyzed for speciated TPH by EPA Method 8015 Modified, and BTEX and MTBE by EPA Method 8020. To avoid sample dilution, the chain-of-custody will specify detection limits. If dilution is necessary because a sample is anticipated to have elevated concentrations, a practical quantification of the sample will be requested. Monitoring Well Placement The location of proposed Monitoring Well SE-MW-51(P) is in the downgradient direction (northwest) from the former South Tank Farm and Refinery. This downgradient direction was determined by adding the groundwater flow direction vectors from the two areas with the highest TPHg and benzene concentrations or Liquid Phase Hydrocarbons (LPH) together to get a downgradient vector along which the proposed well could be located. After requesting access to the PG&E property to install the well, SECOR was successful in arranging a meeting with PG&E personnel at the subject site to discuss the location of the well. Based on the facility operations and structures, a location was agreed upon for the installation of the downgradient groundwater monitoring well, which would not interfere with ongoing operations and was centrally located and sufficiently downgradient for initial assessment. This location is also removed from potential source areas at PG&E, such as the ponds. A workplan amenable to both World and PG&E was then negotiated and submitted to the CRWQCB. Moving the proposed well location further west, and north of SE-MW-20 would be in a downgradient direction of that well but only from a limited number of wells with reported TPHg and benzene concentrations. In addition, a well in this location would not be directly downgradient from the South Tank Farm and Ref'mery which is the L4447 Mr. David Troop, California Regional water Quality Board June 29, 1998 Page 2 main source area of dissolved- and liquid-phase hydrocarbons. Based on the summary of the PG&E data in the aforementioned CRWQCB letter, it appears that temporary wells (B-2, B-3, and B-4) were installed in the downgradient direction of SE-MW-20. Groundwater grab samples collected for analysis from these temporary wells show non-detectable TPHg concentrations (<500 ug/1). Though the PG&E data is limited, the concentrations suggest that the extent of hydrocarbon impact to groundwater west of proposed Well SE-MW- 51(P) and north of SE-MW-20 maybe limited and not provide additional pertinent information. Moving the proposed well or installing a second well would require additional negotiations with PG&E, which could be time consuming and delay compliance with the CAO. Obtaining a representative groundwater sample from the initial downgradient well for comparison with the PG&E grab sample will help in determining if further groundwater assessment is warranted and where additional off-site wells may be needed. Time Schedule SECOR anticipates that the CRWQCB will review SECOR's Workplan clarifications within approximately one to two weeks of receipt. One to two weeks will then be required for permitting, scheduling, and notifications of the involved parties. Fieldwork is anticipated for the beginning of August 1998. Fieldwork will require approximately two days to complete (one day for well installation and a partial day for groundwater purging and sampling), depending on the encountered field conditions. Soil analytical results should be received from the laboratory within two weeks of the drilling. The final assessment report will be submitted to the RWQCB, WORLD, and PG&E approximately four weeks after the final analytical results are received. Conclusions At this time, SECOR recommends proceeding with the plan to install one centrally located downgradient monitoring well at the SE-MW-51(P) location. Based on the results from the proposed well, recommendations for additional assessment can be proposed to fill in data gaps, if warranted.

TROOP Senior Engineer Staff Engineer DATE: 22 May 1998 SIGNATURE: SUBJECT: WORKPLAN FOR INSTALLATIONAND SAMPLING OFA GROUNDWATER MONITORING WELL, SUNLAND REFINER Y, BAKERSFIELD, KERN COUNTY I have reviewed the subject report (Report), dated 12 March 1998 and prepared for World Oil Corporation (World), for plume delineation activities at Sunland Refinery (Sunland). The following represents my impression of the proposed work. INTRODUCTION Sunland Refining Corporation occupies approximately 200 acres of land adjacent to the Kern River channel in the northwestern portion of the City of Bakersfield. The site, which has been undergoing decommissioning activities, consisted of three tank farms (West, North and South Tank Farms) which contained approximately 40 aboveground tanks. The South Tank Farm contained the main refinery facilities including crude oil processing towers and a catalytic reformer unit. For approximately forty years, the company discharged wastewater generated from crude oil refining activities to a series of wastewater ponds located in the West Tank Farm. Discharge to the ponds has halted and the ponds have subsequently been decommissioned and closed. Cleanup of soils and groundwater is on a time schedule regulated by Cleanup and Abatement Order No. 95-702. The lateral extent of affected groundwater remains undefined to the northwest direction from the west tank farm. For approximately the past two years World has been negotiating with PG&E in order to gain access to property which is utilized by the Kern Steam Plant. Access has apparently been granted by PG&E to World for placement of one off-site monitoring well, which forms the basis of this Report. SUMMARY OF PROPOSED WORK In order to achieve lateral plume delineation, World has proposed placing a single monitoring well on land owned by. PG&E that houses the Kern Steam Plant. The proposed groundwater monitoring well will be pladed approximately 800 feet north of the West Tank Farm boundary. No rationale was provided in the work plan for selecting this location versus a location closer and/or in a more westerly direction. This comment has been relayed to Word's consultant and a response should be provided prior to drilling activities. The rationale for siting an additional monitoring well more westerly is tied to current sampling data from Sunland monitoring well SE-MW-20, which is a nested well completed in the shallow and deeper groundwater-bearing zones. Recent sampling data from the first quarter ReCyCled Paper Our mL~ion i~ to prezerve and enhance ']~ quality of California3 ~m,e, re,ource$, and em'ute their proper allocation and e.~cient use for the benefit of present and future generation.t ' SUNLAND REFINERY - 2 - 22 May 1998 PROPOSED OFF-SITE MONITORING WELL BAKERSFIELD, KERN COUNTY sampling event reveal benzene concentrations of 1300 pg/l and 1600 p.g/l in the shallow and deeper zones, respectively. In addition, TPHg concentrations were 5200 pga and 6900 p.g/l respectively in the shallow and deep zones. Since the groundwater gradient tends to trend almost exclusively to the northwest, the currently proposed monitoring well location will not achieve delineation in the area north and northwest of SE-MW-20. This issue should be addressed in the aforementioned request for the rationale on well placement. The single monitoring well will consist of a four-inch diameter PVC pipe with 0.02 PVC screen. Soil sampling will be conducted at five foot intervals with soil samples screened for laboratory testing based upon the results of field testing utilizing either a photo or flame-ionization detector and lithology. Monitoring well screen length has been proposed to extend 25 feet above and below the groundwater surface for a total screen length of fifty feet. The rationale for such an extended screen length was not provided in the report, however, a call to World's consultant attributed this to the dynamic groundwater conditions. Given the history of dynamic groundwater fluctuations in this area, this is appropriate provided provisions to avoid sample dilution are provided to staffpfior to groundwater sampling. PG&E Until .recently, very little geotechnical work had been conducted at the PG&E facility except for shallow soil sampling (3 to 5 feet in depth) as a result of the Coffee Road realignment project. These shallow borings on PG&E property showed the presence of surficial soil contaminants like kerosene and diesel. A check of Regional Board and Kern County Environmental Health Department (KCEHD) records show no regulatory actions to date at this facility. It was noted that in discussions with KCEHD personnel that PG&E had recently advanced a series of five deep soil borings. PG&E voluntarily provided Board staff with the laboratory results of these borings in a document received 17 April 1998. The on-site PG&E investigation involved advancing a series of borings, of which five were advanced to groundwater and three were shallow hand auger borings. Figure 1 shows the approximate location of the deep borings in relation to Sunland refinery. Table 1, below, provides the specifics of this sampling · event. Three of these borings 03-2, B-3, and B4) are located north of Sunland's former West Tank Farm, and provide additional off-site sampling data for shallow groundwater quality. Each of the five deep soil borings were advanced using hollow stem auger drilling techniques. Soil samples were collected at depths of 5, 10, 20, 40, and 60 feet below ground surface (bgs). Samples below this depth were collected at thirty foot intervals and also within ten feet of the groundwater surface (70 to 115 feet bgs). Following completion of soil sampling, each boring was converted into a temporary monitoring well constructed with four-inch diameter PVC blank casing and ten foot factory slotted sc~en. Following insertion of the casing, groundwater was allowed to enter the screened area and return to static levels, at which time a disposable bailer was lowered and samples extracted.. Nothing was provided with the results to indicate that the temporary wells were purged prior to sampling. Groundwater samples were filtered in the field prior to testing.

All of these soil borings were below their respective method detection level except B-3, which at 80 feet bgs showed a total concentration of gasoline hydrocarbons of 1600 pg/kg. Since shallower soil samples were below detection levels, it is possible that the presence of hydrocarbons at this depth might be indicative of groundwater transport rather than a surface event such as a spill or leak. Conversely, given that mils in this area are sands and gravels, and B-3 was advanced within the footprint of a former drainage pond, facilitated transport from percolation of surface water could also explain the nondetectable concentration found in shallower soil samples. What actually accounts for presence of hydrocarbons at this depth depends, in large part, on past land use patterns and the constituents present in past discharges to the drainage pond. The one time groundwater sampling event at PG&E provides some information on the lateral extent of petroleum hydrocarbons possibly emanating from the Sunland refinery. Care should be exercised in interpreting these results for the following reasons: a) No BTEX analyses were conducted on groundwater samples. b) Sampling for dissolved constituents was not conducted. c) Groundwater samples were indicative only of water table surface conditions as they existed at that time. CONCLUSIONS 1. Provisions to avoid sample dilution should be provided prior to sampling groundwater. 2. The rationale for monitoring well placement should be submitted and should include the rationale for not siting an additional monitoring well(s) in the area north/northwest of monitoring well SE-MW- 20.

(WORLD), SECOR International Incorporated (SECOR) is pleased to present the first quarter groundwater monitoring report for the Sunland Oil Refinery. In addition, SECOR has prepared this cover letter to request California Regional Water Quality Control Board - Central Valley Region (RWQCB) approval to begin biannual groundwater sampling at the Sunland site. This letter also addresses Item 1 of the RWQCB letter dated February 10, 1998, requesting further examination of chloride and sulfate concentrations detected during the wastewater pond closure activities and their relevancy to overall refinery closure activities. Biannual Monitoring Quarterly groundwater monitoring has been conducted at the site for nine consecutive quarters beginning in the first quarter of 1996. The data collected during these nine sampling events is presented in the summary Tables 1 and 2 within the attached quarterly groundwater monitoring report. This request for biannual monitoring is a follow-up to the initial request of October 13, 1997. At that time, the RWQCB required an additional two consecutive quarters of monitoring, to evaluate the effects of expected high rainfall totals during the winter months. This follow-up request for biannual sampling is based of the following site conditions: · Hydrocarbon concentrations in groundwater have remained relatively stable across the site for nine consecutive quarters through the first quarter of 1998 despite higher groundwater levels. The groundwater gradient has been consistently directed toward the northwest. The lateral limit of petroleum hydrocarbon impact in groundwater, as defined by unimpacted perimeter monitoring wells, has also been stable over the past nine quarters. · Groundwater sampling ccmducted to date indicates that the lateral extent of dissolved-phase hydrocarbons in groundwater has been adequately defined in all directions except to the northwest. WORLD has acquired access to the PG&E power generating facility for additional assessment to the northwest of the subject site. A Workplan for the installation of one down-gradient well on the PG&E site has been submitted to the RWQCB for approval. Fieldwork will commence upon receiving RWQCB approval. L4270 Mr. David Troop Regional Water Quality Control Board April 15, 1998 Page 2 · Potential hydrocarbon sources beneath the former West and South Tank Farm are being actively remediated. Currently two Paragon ET-250's, and two air sparging systems are operational at each site. In addition, a free product removal system is operational at the former West Tank Farm. Through the end of 1997, over 211,500 pounds of hydrocarbon have been removed from the subsurface, which will reduce the hydrocarbon impact to groundwater over time. Based on the information presented above, SECOR believes that biannual groundwater monitoring is justified and requests that the RWQCB modify the monitoring requirements as such. We propose that the second and fourth quarter 1998 groundwater sampling be eliminated and that groundwater sampling be conducted only during the first and third quarters of 1998. Wastewater Pond Closure In correspondence dated February 10, 1998, the RWQCB requested additional evaluation of the potential impact of elevated chloride and sulfate concentrations detected beneath the former wastewater ponds on overall ref'mery, closure activities. On behalf of WORLD, SECOR proposes that down- gradient monitoring wells SE-MW-20(S) and SE-VE/MW-29(D) be sampled for chloride and sulfate concentrations during future biannual monitoring events. This additional sampling is proposed to address the potential impact to groundwater from the chlorides and sulfates concentrations detected in soil during closure activities. Once sufficient groundwater data is collected to establish a trend for chlorides and sulfates in groundwater, a determination can be made about the relevancy to overall refmery closure activities if any. Closing We appreciate your attention to this project, and if you have any questions or need any additional information, please feel free to contact either of the undersigned at (805) 230-1266.

Each well was located and inspected upon arrival at the site. Using a SolinstTM Water Level Meter and/or an oil/water interface probe, each well was then gauged for depth to groundwater, depth to floating product (if present) and total well depth. Gauging devices were decontaminated between each well using a triple-rinse method of tap water and non-phosphate detergent, tap water, and then deionized water. Wells were also gauged in expected order of increasing hydrocarbon concentrations to prevent cross-contamination. The sampling sequence was based on the analytical results obtained during the previous quarters sampling event. Groundwater Purging. Each well was purged following gauging. At least three casing volumes of groundwater was removed from each well using a PVC bailer. During purging, water parameters including pH, temperature, conductivity, and turbidity were monitored to calculate stabilization within 10 % of each parameter and ensure that groundwater, representative of the aquifer, was entering the well. The bailer was decontaminated between each well using a triple-rinse method of tap water and non-phosphate detergent, tap water, and then deionized water. Wells were also purged in expected order of increasing hydrocarbon concentrations 'to prevent cross-contamination. Groundwater Sampling. After purging, wells were allowed to recharge to at least 80 % of their original capacity prior to sampling. Groundwater samples were collected using a polyethylene disposable bailer attached to clean string. Samples were decanted into containers provided by the laboratory appropriate to the analysis to be performed. The containers were capped with TeflonTM septa, labeled, and placed on ice for' transport to State-certified American Analytics Laboratory, in Chatsworth, California. New sampling equipment (string, bailer, etc.) was used on each well to eliminate the possibility of cross-contamination. A quality control sample was collected and submitted with the groundwater samples to the laboratory. A trip blank, provided by the laboratory, was kept in the sample cooler with the collected groundwater samples and handled similarly. SECOR initiated a Chain-of-Custody Record in the field immediately following sample collection to accompany the samples to the laboratory. Product Removal. Product Removal was conducted from wells MW-7, MW-9, MW-16, and MW-42, using the automated liquid petroleum hydrocarbon (LPH) recovery system. Removed product is stored in a poly-tank for later transport to a recycling facility. Currently only wells MW-7 and MW-42 are online due to the low product thickness in the other wells. Waste Disposition. Purge water generated during this monitoring event was stored on-site in labeled and sealed 55-gallon drums. Purge water drums were stored on pallets in a secured area of the South Tank Farm pending off-site recycling. Purge water was trucked to DeMenno/Kerdoon in Compton for recycling. Bailed product is currently stored onsite awaiting proper disposal. Waste recycling/disposal documentation will be provided to the RWQCB upon receipt.

(WORLD) for the Sunland Oil Refinery site (Sunland) in Bakersfield, California (Figures 1 and 2). INTRODUCTION This report on WORLD's remedial activities in compliance with the California Regional Water Quality Control Board - Central Valley Region's (CRWQCB) Cleanup and Abatement Order (CAO) No. 95-702 dated April 27, 1995, has been prepared pursuant to the "Final Judgement Pursuant to Stipulation" (KCSC No. 228 399-RA). The CAO directs Sunland Refining Corporation to address petroleum hydrocarbon impacted soil and groundwater documented at the subject site during previous soil and groundwater investigations. Item 8 of the Final Judgement requires the submittal of an annual summary regarding the status of site remediation efforts to contain and cleanup groundwater and soil contamination under CAO No. 95-702. This report summarizes the remediation data and efforts for the calendar year 1997 and where appropriate includes short descriptions of planned remedial activities for 1998. The Sunland facility is divided into three main areas: the former West Tank Farm (Figure 3), the refinery plant/former South Tank Farm (Figure 4), and the existing North Tank Farm (Figure 5).

Kern County District Attorney's Office March 30, 1998 Page 2 E~C~IVESUMM~Y Based on the progress of 1997 remedial activities outlined above, the following summary and conclusions are presented: · Remedial Activity - Soil and groundwater remediation is proceeding as planned on both the former West and South Tank Farms using soil vapor extraction, air sparging, and liquid petroleum hydrocarbon recovery systems (West Tank Farm only). For 1997., approximately 169,200 pounds of hydrocarbon mass have been removed from the subsurface at a steady rate. Monitoring of remedial progress by hydrocarbon concentrations in extracted soil vapor and groundwater indicate sufficient hydrocarbon mass remains in the subsurface to continue active remediation in accordance with the compliance tasks for containment and cleanup required in CAO 95-702. The existing remedial system will be upgraded to a high-capacity extraction system in 1998. · Wastewater Pond Closure - Based on pond closure activities that have been performed, as well as the analytical data collected during this investigation and the Salt Load Investigation, SECOR concluded that the former wastewater pond facility and underlying soils represent a low environmental risk to groundwater underlying the site. On February 10, 1998, the CRWQCB agreed with SECOR's findings that the decommissioning and closure of the ponds were adequate and that characterization and disposal activities removed possible hazards associated with the ponds. · Well Installations - A total of 18 remediation and monitoring wells were installed in 1997 to accommodate the construction of the Coffee Road overpass' in the Greater Bakersfield Separation of Grade District (SOGD) right-of-way or to upgrade the remediation systems for additional vapor extraction and air sparging. Of the 18 wells seven were installed for the future installation of the high capacity extraction system. · Off-Site Assessment - Assessment to characterize the extent of contaminants in groundwater, as required in CAO 95-702, has been completed in all directions except the down-gradient direction to the northwest, where the dissolved-phase plume extends off site. In 1997 and early 1998, WORLD completed negotiations for access to PG&E's Kern Steam Plant for the installation of one off-site groundwater monitoring well. Final assessment activities are planned for 1998. REMEDIAL ACTMTY FOR 1997 Soil and Groundwater Remediation Soil Vapor Extraction (SVE) and Air Sparging (AS) remediation systems were operated at the South Tank Farm (STF) for all of 1997 and at the West Tank Farm (WTF) since April of 1997. In addition, during September 1997, a liquid-phase hydrocarbon (LPH) recovery system was installed SECOR John T. Mitchell, Esq. Kern County District Attorney's Office · March 30, 1998 Page 3 at the WTF to replace hand bailing product recovery from certain wells. Operation of the LPH system is ongoing. Hydrocarbon recovery data for each of the remediation systems located at the site is provided below and in previously submitted quarterly status reports, SVE/AS remedial operations are summarized in the monthly and quarterly tables presented in Appendix A. During the year, the SVE systems operating at the former South and West Tank Farms removed a total of 169,200 pounds of hydrocarbons. Through 1997, SVE is responsible for removing a cumulative total of 211,565 pounds of hydrocarbons from subsurface soil and groundwater since remedial operations began in March 22, 1996 (Figure 6). Through the end of 1997, more than 347 gallons of LPH have been removed by a combination of hand bailing and pumping (approximately 300 gallons in calendar year 1997). LPH recovery Operations are summarized in quarterly tables presented in Appendix B. Monitoring Monitoring of subsurface conditions during remedial activities has been performed through weekly operation and maintenance (O&M) of SVE/AS systems and through quarterly groundwater gauging and sampling. Weekly O&M activities entail measuring system parameters including extraction flow rates, system vacuum, processing temperatures, and utility usage for electricity and supplementary natural gas. Hydrocarbon concentrations in the vapor stream are measured for the total system, and from individual extraction wells by screening instrumentation in the field and from samples collected for laboratory analyses. From the weekly data, destructive efficiency of the system is calculated, operation of the system is optimized, and the mass of volatile hydrocarbons removed from the subsurface is calculated. Operational data is summarized in quarterly reports (Appendix A), and the cumulative mass of extracted hydrocarbons is plotted (Figure 6). In 1997, the SVE systems operated at a destructive efficiency of 99.7% to 100%. The systems were operational approximately 89 % of the year. Based on laboratory analyses of extracted total petroleum hydrocarbon (TPH) and benzene, hydrocarbon concentrations in vapor have remained relatively constant over the course of the year, indicating that the mitigation process is effective and that sufficient hydrocarbon remains in the subsurface to operate the systems at full capacity. Quarterly groundwater monitoring has measured a gradual increase in groundwater elevations (average of 16.5 feet) from fourth quarter 1996 through fourth quarter 1997 (Table 1) due to an increase in groundwater recharge in the region due to heavy snow pack in the Sierra Nevada Mountains and above-average seasonal rains in recent years. Hydrocarbon concentrations in groundwater have remained relatively consistent over time in the majority of the wells with a slight decrease in concentration and lateral extent in the south tank farm area. A slight increasing trend in hydrocarbon concentrations and the lateral extent of product has been noted beneath the former West Tank Farm, concurrent with the increase in groundwater elevations (Table 2). Measurements obtained by SECOR during the December 1997 site groundwater monitoring event showed the depths to groundwater beneath the site ranging from approximately 60 to 96 feet bgs: SECOR John T. Mitchell, Esq. Kern County District Attorney's Office March 30, 1998 Page 4 The calculated groundwater gradient was approximately 0.013 feet/foot (1.3%) to the northwest, away from the Kern River. Groundwater data is summarized in the 1997 Quarterly status reports presented in Appendix C. Quarterly groundwater contour and hydrocarbon concentration maps for 1997 are presented in Appendix D. Remediation Plans The design for installation of a high capacity, emission control device (flare) to upgrade the existing remedial systems operating on the former West and South Tank Farms has been finalized. The high-capacity remediation system has been permitted and the Authority to Construct (ATC) has been received from the Air Pollution Control District (APCD). Delivery and installation of the high capacity system is scheduled for the Second Quarter of 1998. WASTEWATER DISCHARGE POND CLOSURE The four wastewater discharge ponds located west of the former west tank farm (now west of the Coffee Road overpass) were decommissioned in July through October 1997. The ponds comprised a portion of the Sunland Oil Refinery's wastewater treatment facility (Figure 7). Closure activities that were completed in 1997 consisted of the following: · Characterization, removal, and disposal of sludge from Ponds 1 and 2; Demolition of the concrete liner within Pond 1; · Collection of soil samples from beneath each of the four ponds for laboratory analysis; · Backfilling the ponds and grading the site level; and · Preparation and submittal of a closure report to CRWQCB. Approximately 2 feet of sludge was present Within the bottoms of both Pond 1 and Pond 2. Between July 30, 1997 and August 6, 1997 all waste material was removed and disposed of properly. Following characterization of the concrete liner in Pond 1 as non-hazardous, the surface of the pond was steam cleaned on August 21 and 22, 1997 to remove sludge residue from the concrete prior to recycling. The cleaned concrete liner was removed on August 28, 1997. Subsurface soil underlying the four former wastewater ponds was not impacted by petroleum hydrocarbons below a depth of 5 feet bgs, thus historic operation of the ponds has not contributed petroleum constituents to the subsurface. However, limited areas of heavier-end (C~6-Cn~) hydrocarbon impact were encountered within soil comprising the berm of Pond 1 as a result of hairline cracks within the pond liner. The lateral and vertical extent of these impacted areas was minimal and does not represent a significant environmental concern. The CRWQCB concurred that 'the risk associated with the surface hydrocarbons was insignificant and allowed the limited areas of impacted soil to be used as backfill during the grading of Pond 1. [4 ~ ~ 7 SECOR John T. Mitchell, Esq. Kern County District Attorney's Office March 30, 1998 Page 5 Soil samples collected from the vadose zone beneath the ponds contained chloride concentrations ranging from 170 to 360 mg/kg and sulfate concentrations ranging .from ND (< 10 mg/kg) to 730 mg/kg. The chemistry of wastewater entering the ponds was analyzed during the Salt Load Investigation performed by SECOR in October 1996 and found to be dominated by chloride ions and sulfate ions. Detected chloride and sulfate ions in subsurface soil are therefore likely the result of wastewater infiltration through the vadose zone underlying the ponds. Pond grading and backfilling was performed in two episodes. Ponds 3 and 4 and portions of Pond 2 were backfilled between February I and February 11, 1997. Pond 1 and the remaining areas of Pond 2 were completely backfilled between October 6 and October 10, 1997. SECOR generated and submitted a closure report to the CRWQCB entitled: Wastewater Pond Closure Report dated December 22, 1997. REMEDIATION AND MONITORING WELL INSTALLATIONS During 1997 (including the last two weeks of 1996), 16 new wells and two redrilled wells were installed at the Sunland Refinery. All work was completed under the oversight of the CRWQCB. · Six air sparging (AS) wells: Two air sparging wells, SE-AS-30 and -31, were completed within the refinery area and four air sparging wells, SE-AS-32, -33, -39, and -41, were completed within the former West Tank Farm, between the Greater Bakersfield Separation of Grade District (SOGD) right-of-way and Coffee Road; · Five vapor extraction/air sparging (VE/AS) wells: Wells SE-VE/AS-34 through SE-VE/AS-38 were installed within the SOGD right-of-way; · One soil vapor extraction (SVE) well: Well SE-SVE-40 is installed within the former West · Tank Farm; and · Two groundwater monitoring wells (MW), SE-MW-9(R) and SE-MW-18(R): These two wells were installed adjacent to the SOGD right-of-way. Both wells are replacement wells, which were required due to the abandonment of the original groundwater wells that were located within the footprint of the SOGD right-of-way. · Seven additional SVE wells (SE-VE-47, -48, -49, and -50) and AS/SVE nested wells (SE-AS/VE-44, -45, and -46) were installed on the former South Tank Farm. The new remediation wells were installed for later connection by common conveyance piping and manifold to the planned high capacity remediation system. The locations of all wells drilled during the current phase of drilling are depicted in Figure 2. L4117 SECOR John T. Mitchell, Esq. Kern County District Attorney's Office March 30, 1998 Page 6 OFF-SITE ASSESSMENT Compliance with the cAo for the Sunland Refinery includes defining "the lateral and vertical extent of contaminants in groundwater" (Item 3). The extent of hydrocarbon impacted groundwater has been completed in every direction except in the down-gradient direction to the northwest. In 1997 and early 1998, WORLD completed negotiations to obtain access to the Pacific Gas and Electric Company's (PG&E) Kern Steam Plant to initiate off-site assessment. On behalf of WORLD and with concurrence from PG&E, SECOR submitted a Workplan to the CRWQCB for off-site assessment of soil and groundwater conditions to be completed in the second quarter of 1998. The proposed groundwater monitoring well will be installed north-northwest of the former West Tank Farm, on the PG&E Kern Steam Plant property. Assessment of the extent of hydrocarbon impacts will be completed when the characterization of the down-gradient direction is performed. The location of proposed monitoring well SE-MW-51(P) is shown on Figure 2.

(WORLD), presents this Workplan to conduct additional assessment for the Sunland Refinery, located at 2152 Coffee Road in Bakersfield, California (Figure 1). The additional work is required to evaluate the extent of adsorbed- and dissolved-phase petroleum hydrocarbons in soil and groundwater northwest of the former West Tank Farm, as directed by the California Regional Water Quality Control Board - Central Valley Region (Attachment A) [RWQCB; lead agency]: This document is also intended to support remedial action, as proposed pursuant to Cleanup and Abatement Order (CAO) No. 95-702, dated April 27, 1995, issued by the RWQCB. The CAO directs Sunland Refinery to address petroleum hydrocarbon impacted soil and groundwater documented at the subject site during previous soil and groundwater investigations. The additional assessment will include the advancement of one soil boring (SE-MW-51) which will be completed as a groundwater monitoring well. The proposed groundwater monitoring well will be located north-northwest of the former West Tank Farm, on the Pacific Gas and Electric Company's (PG&E) property, know as the Kern Steam Plant. This Work'plan presents the objectives and methods for installing one groundwater monitoring well and collecting groundwater samples. 2.0 SITE BACKGROUND From 1985 through 1996, soil and groundwater assessments were conducted at the site. Assessment activities included two soil vapor surveys in 1987 by Environmental Research and Technology (ERT) (65 and 39 vapor points, respectively) and the drilling of 47 soil borings by five different consultants (including the installation of 19 groundwater monitoring wells). In 1996, SECOR installed 10 additional wells at the site, including two nested wells adjacent to the wastewater discharge ponds. Through October 1997, SECOR installed 17 additional wells at the site, including; seven soil-vapor extraction, eight air sparging-soil vapor extraction and two air sparging wells. Previous site work indicates the presence of petroleum hydrocarbons in vadose zone soil beneath the site. The vadose zone extends from near surface grade to approximately 66 to 100 feet beneath the site. Based upon the information collected during site assessment activities conducted since 1985, lateral delineation of the hydrocarbon plume in soil has been achieved in all directions except to the northwest of the subject site. The vertical extent of hydrocarbons in soil is limited by unconfined groundwater ranging from approximately 66 to 100 feet bgs (as measured September 8, 1997). 2.1 SITE GEOLOGY AND HYDROGEOLOGY Soils encountered to the maximum depth of approximately 197 feet below ground surface (bgs) beneath the site consist primarily of well-graded to poorly-graded sands, gravelly sands, silty sands, and minor interbeds of silt and sandy clay. SECOR Offsite Well Installation Workplan Sunland Refinery March 12, 1998 Bakersfield, California Page 2 Water-bearing sediments beneath the site consist of late Tertiary and Quaternary age sand and gravel deposits of Sierran origin. Lacustrine deposits, contemporaneous with the Corcoran Clay Formation, are reported to separate the upper and lower confined aquifers. Well data suggests that the Corcoran Clay or equivalent aquitard does not underlie the site (Dale, 1966); however, lower-energy deposits of silt, fine sand and clay are generally encountered below 600 to 800 feet bgs. Groundwater flow direction is interpreted as being westward in the vicinity of the site, based on September 1993 measurements (KCWA, 1994). Measurements obtained by SECOR during the August 1997 site groundwater monitoring event showed the depths to groundwater beneath the site ranging from approximately 58 to 100 feet bgs. The calculated groundwater gradient was approximately 0.017 feet/foot (1.7%) to the northwest, away from the Kern River. Aquifer testing conducted by ENSR in December 1988 revealed an apparent groundwater velocity of 10 and 25 feet per day, with a transmissivity of approximately 1,000 to 2,500 gallons per day per foot (gpd/ft) (ENSR, 1989). Data for past groundwater monitoring episodes indicates a wide fluctuation in the depth to groundwater over time for the unconfined aquifer beneath the site. Heavy snow pack in the Sierra Nevada Mountains and above-average seasonal rains in recent years have contributed to a rise in the groundwater levels measured at the site. 3.0 DRILLING, WELL INSTALLATION, SAMPLING AND REPORTING 3.1 PRE-FIELD ACTIVITIES All field activities will be completed with safety as a foremost concern. A site-specific health and safety plan (HASP included as Appendix B) has been prepared for the drilling and well installation activities. All SECOR employees at the site, as well as any other on-site subcontractors or regulatory personnel will be required to familiarize themselves with and sign the HASP in an attempt to minimize safety hazards. Prior to drilling SE-MW-51, the boring will be pre-marked and cleared of underground utilities by PG&E, Underground Service Alert, and a private geophysical locating firm. In addition, the upper five feet of the borehole will be excavated with a hand auger and widened to the width of the augers with a post-hole digger. The proposed location of SE-MW-51 is depicted in Figure 2. 3.2 SOIL BORING AND SAMPLING An experienced SECOR geologist or environmental scientist working under the direct supervision of a California Registered Geologist will conduct all sampling. Prior to drilling the soil boring, the augers will be steam cleaned to prevent cross-contamination from previous sampling events. Soil sampling will be conducted at five-foot depth intervals for the purposes of chemical analyses and Unified Soils Classification System (USCS) descriptions. Laboratory analyses of selected soil samples will be based upon field photo-ionization detector (PID) or flame-ionization detector (FID) screening levels and SECOR Offsite Well Installation Workplan Sunland Ref'mery March 12, 1998 Bakersfield, California Page 3 lithology. Soil samples for potential chemical analyses will be immediately sealed with TeflonTM film and capped to avoid possible loss of volatile constituents. The sample sleeves will be labeled and placed in a chilled cooler for delivery to the analytical laboratory. All sampling equipment will be cleaned in an aqueous solution of Liquid-NoxTM cleanser or equivalent, rimmed with tap water, and rinsed a second time with deionized water to prevent cross-contamination between sampling intervals. Soil cuttings generated during drilling activities will be placed in DOT- approved 55-gallon drums. Each collected soil sample will be submitted under chain-of-custody protocol to a California State- certified analytical laboratory for analysis. No less than five soil samples will be selected for chemical analysis. The soil samples will be analyzed for total petroleum hydrocarbons as gasoline and diesel (TPHg and TPHd) by EPA Modified Test Method 8015, and for volatile aromatic compounds (BTEX) by EPA Method 8020. 3.3 GROUNDWATER MONITORING WELL INSTALLATION AND SAMPLING The following procedures will be used when installing the monitoring well at the site. The well borehole will be drilled using the procedures described above. SE-MW-51 will be constructed with 4-inch diameter schedule 40, PVC well screen (0.02-inch slot) and schedule 40, polyvinyl chloride (PVC) casing. The well screen will extend approximately 25 feet below the observed groundwater surface and 25 feet above. Clean filter pack (No. 2/12 sand) will be placed into the well annulus. The filter pack will extend approximately two feet above the top of the monitoring well screen. Low permeability bentonite clay will be placed above the filter pack. The seal will have a minimum thickness of five feet. A grout seal will be installed from the top of the bentonite clay to approximately three feet below ground surface. The surface will be completed with a 12-inch diameter, traffic-rated well box. The anticipated well construction detail is presented as Figure 3. Prior to installation, the well will be permitted with the Kern County Environmental Services Department. During well installation and prior to installing the bentonite seal, the well will be properly developed using the drill rig. To properly place the sand pack, the well will be surged with a rig-mounted, surge block for at least 15 minutes, or until settling of the sand ceases. The newly installed well will be professionally surveyed for precise horizontal and vertical coordinates. Horizontal coordinates will be determined to the nearest foot relative the existing well network and nearby municipal benchmark. The elevation of the measuring point and land surface at each well will be surveyed to the nearest 0.01 foot relative to the National Geodetic Datum (mean sea level). Groundwater sampling is currently conducted at the Sunland Refinery on a quarterly basis under the requirements set forth by the RWQCB. If scheduling permits, the monitoring well installed on the PG&E facility property will be sampled concurrently with the wells at the Sunland Refinery. During each sampling event, the wells without liquid-petroleum hydrocarbons (LPH) are gauged, purged, and sampled for analyses. Liquid level measurements will be referenced to a surveyed measuring point (notched and labeled with indelible ink), located on the top of the PVC well casing. All water and SECOR Offsite Well Installation Workplan Sunland Refinery March 12, 1998 Bakersfield, California Page 4 product level measurements will be taken at least two times to check the reproducibility of the measurement data. If it is found that the measurement cannot by reproduced, a second set of data will be collected. Water level data will be collected until levels can be reproduced. Prior to sampling, the well will be purged of no less than three volumes of water to ensure that representative formation water is sampled. Groundwater generated during sampling activities will be placed in DOT-approved 55-gallon drums. Wells are to be purged in order of expected increasing hydrocarbon concentration to minimize potential cross-contamination. Well purging procedures to be used priOr to groundwater sample collection are as follows: 1) Identify the well and record its designation and pertinent information on the header of the Groundwater Sample Field Data Sheet. 2) Compute the volume of groundwater in the well casing using total height of the water column and diameter of the well casing. 3) Record field parameters (e.g., temperature, pH, specific conductance or electrical conductivity, and turbidity) at equal time intervals during purging. At least one reading will be collected during purging of each well casing volume of groundwater. Stable consecutive readings (within 20 percent of previous readings) will be obtained for all of these parameters prior to sample collection. 4) Containerize purge/development water in DOT-approved drums or proper container for characterization and subsequent disposal/recycling under proper manifest. Drums will be labeled with a waste label and indelible ink, sealed, and relocated to the Sunland Refinery. 5) Items, such as bailers, rope, cleaning rags, and gloves, will be disposed of in a proper manner. 6) If measurable LPH is observed in the well, the depth to product and water will be recorded on the water-sampling log, however, groundwater will not be purged and a grOUndwater sample will not be collected. Each collected water sample will be submitted under chain-of-custody protocol to the analytical laboratory for analysis. The groundwater samples will be analyzed for speciated TPH by EPA Method 8015 Modified, and BTEX and MTBE by EPA Method 8020. 3.4 SOIL CUTTINGS AND WASTEWATER HANDLING Soil cuttings, purge water, and decontamination water generated during drilling and sampling activities will be placed in labeled, DOT-approved, 55-gallon steel drums and stored on-site pending receipt of the analytical results. Soil cuttings and wastewater will be characterized as hazardous or non-hazardous based on the hydrocarbon source and laboratory analyses. SECOR Offsite Well Installation Workplan Sunland Refinery March 12, 1998 Bakersfield, California Page 5 All drams will be labeled with contents, depths, and generator information. The Sunland Refinery will be noted as the generator. Following receipt of analytical results for soil and groundwater the waste will be removed from the PG&E facility by a licensed hauler under appropriate manifest or bill of lading. All waste will be properly disposed of or recycled in accordance with applicable Federal, State, and local regulations under the Sunland Refinery's existing EPA ID number(s), where appropriate. Characterization and transportation activities will comply with required regulations, including 40 CFR Parts 261,263; 49 CFR Parts 171,172; and CCR Tile 22. Based on the results of initial groundwater sampling, the collected purged groundwater will be evaluated for hazardous-waste characteristics. If determined to be non-hazardous for the hydrocarbon constituents of concern, primarily benzene, SECOR or WORLD's purging contractor will transport the purged groundwater from the PG&E facility to the Sunland Refinery during subsequent quarterly sampling events for temporary storage prior to removal to a recycling facility. 4.0 REPORT PREPARATION A copy of the soil boring logs, and as built of the groundwater monitoring well will be submitted to the Kern County Environmental Services Department within 14 days following the completion of the well. In addition, a draft copy of the assessment report will be submitted to WORLD approximately two weeks following receipt of the soil analytical results. After incorporating any revisions, the final report will be submitted to WORLD, PG&E and the Central Valley Regional Water Quality Control Board (RWQCB). The assessment report will document the methodologies used for data collection and present the findings of the investigation. Analytical data will be presented in tabular format and annotated on the appropriate figures. Figures will include a site location map, site map, and hydrocarbon concentrations in soil map. The report will contain all pertinent documentation such as permits, laboratory reports, disposal/recycling certifications, and chain-of-custody forms. The final report will be reviewed in its entirety and signed by a State of California Registered Geologist. 5.0 PROJECT SCHEDULE SECOR anticipates that the RWQCB will review SECOR's Workplan within approximately two to three weeks of receipt. One to two weeks will then be required for permitting, scheduling, and notifications of the involved parties. Fieldwork is anticipated for the first half of April 1998. Fieldwork will require approximately 11/2 to two days to complete (one day for well installation and a partial day for groundwater purging and sampling), depending on the encountered field conditions. Soil analytical results should be received from the laboratory within two weeks of the drilling. The final assessment report will be submitted to the RWQCB, WORLD, and PG&E approximately three to four weeks after the final analytical results are received. SECOR Offsite Well Installation Workplan Sunland Refinery March 12, 1998 Bakersfield, California Page 6 6.0 STANDARD LIMITATIONS This work plan has been prepared as a guidance document for a planned field investigation. Situations may arise during the fieldwork that may require modifications to the work plan. Should any modifications be necessary, the changes will be documented in the field records. If actual field conditions result in deviation from this work plan, PG&E, WORLD, RWQCB and KCEHSD will be notified. The exact duration of the fieldwork is unknown and is dependent upon conditions encountered in the field. For purposes of this work plan, the time required for well installation is estimated to be eight to ten hours. All work will be performed under the supervision of a California Registered Geologist as defined in the Registered Geologist Act of the California Code of Regulations.

SCOTT NEVINS FROM: DAVID D. TROOP Seni°r Engineer Staff Enginee, gr DATE: 24 October 1996 SIGNATURE: SUBJECT: REVIEW OF CORRECTIVE ACTION PLAN, SUNLAND REFINERY, BAKERSFIELD, KERN COUNTY I have reviewed the work described in the 30 August 1996 report entitled "Corrective Action Plan", which discusses various technologies for remediation of' affected soils and groundwater at Sunland Refinery. The following is a summary of site conditions and an evaluation of the proposed work. BACKGROUND Sunland Refining Corporation occupies approximately 200 acres of land adjacent to the Kern River channel in the northwestern portion of the City of Bakersfield The site consists of three tank farms (West, North and South Tank Farms) that contain approximately 40 aboveground tanks. The South Tank Farm contains the main refinery facilities including crude oil processing towers and a catalytic reformer unit. The company discharges wastewater generated from crude oil refining activities to a series of unlined percolation ponds located in the West Tank Farm. The discharge of the wastewater is regulated by Waste Discharge Requirement Order No. 90-86. Cleanup of soils/groundwater is on a time schedule regulated by Cleanup and Abatement Order No. 95-702. Sunland historically discharged approximately 16,000 gpd of process wastewater which is treated using the PPI separator and settling tank. After treatment, process wastewater is discharged to the first of four ponds on the west side of the refinery. The first pond (pond I) is concrete lined and utilizes sprayers for additional hydrocarbon volatilization and treatment. A steel skin surrounding the ouffall location is used to trap oil and grease. A stem-driven pump suctions off wastewater from below the water level inside the skin and pumps it through 10 sprayers surrounding the pond. The first pond flows by gravity into the second pond via an underwater pipe. SOIL AND GROUNDWATER ~?ONDITION$ The subject site is underlain by highly sandy soils of ancient river fan deposits. Sedimentary deposits younger than the Kern River formation are present, and consist of alluvial fan, valley stream and flood plain deposits. These are as much as 200 feet thick and consist primarily of unconsolidated sands, some silt and clay deposits, and scattered gravel. Groundwater depths encountered at the last quarterly monitoring event ranged from 80 io 130 feet below ground surface (bgs), and has a gradient calculated at around 0.0! 7 fi/fi to the northwest to west. SUNLAND REFINER~ .'~2 ~ -2- CORRECTIVE ACTION BAKERSFIELD, KERN COUNTY CURRENT STATUS OF INVESTIGATIVE/REMEDIAL A(3'TIVITIE$ I. GROUNDWATER According to Cleanup and Abatement Order (C&A) No. 95-702, the Discharger was to complete the following tasks (Table 1) within the following timeline: .T. able 1. Review of Compliance with Specific Tasks of C&A Order No. 95-702 TASK COMPLIANCE DATE STATUs 3. Complete all work necessary 1 July 1996 Incomplete. The lateral extent to define the lateral and vertical of degraded groundwater has extent of contaminants in been defined except to the groundwater, northwest border of the refinery. The vertical extent of affected groundwater has not been fully defined. 4. Provide a technical report that 1 September 1996 Incomplete. Other than contains a plan and time schedule proposing and conducting pilot to contain and cleanup degraded tests, no complete plan or time groundwater, schedule has been provided. The company has initiated some air sparging pilot testing. 6. Imtiate containment and I November 1996 cleanup of contaminants in groundwater. A review of Table 1 reveals that the delineation of the lateral' extent of groundwater degradation appears complete except to the northwest direction from the west tank farm, while the vertical extent of affected groundwater remains undefined; and a plan and time schedule to contain and cleanup degraded groundwater has not yet been provided. The Discharger is not in compliance with Tasks 3 & 4 of C&A Order No. 95-702. 1I. SOILS A 90 day, continuous operation soil vapor extraction system (SVES) pilot test was conducted in the area of the proposed overpass. Results of the pilot test showed soil vapor extraction to be a viable remedial altemative as approximately 6000 pounds of hydrocarbons were removed from vadose zone soils and destroyed. The Discharger is in the process of relocating and reinstalling the existing SVES and mobilizing an additional SVES to augment the existing system. Wastewater discharged to disposal pond I has contained excessive concentrations of benzene, chloride, nitrogen, TDS, and EC. Evidence in the file indicates past discharges to this pond have, at various times, SUNLAND REFINERY -3- CORRECTIVE ACTION PL.~,N BAKERSFIELD, KERN COUNTY contained sufficient benzene concentrations to be classified as a hazardous waste under Title 22, California Code of Regulations, Section 66261.24. There are questions about: 1. Whether or not hydrocarbon pollutants currently exist in the soil profile 2. The pollutant cOncentrations 3. The vertical extent of these concentrations 4. The potlntial of the pollutants to migrate to groundwater in the future 5. What remedial measures are necessary to protect groundwater from soil pollutants in the future In order to characterize soils below the ponds, the Discharger proposes: a. To extend a single soil boring in between ponds 1 and 2, which are separated from each other by an 8 foot-wide berm. b. To place another boring in close proximity to the ponds. It is questionable whether the proposed borings will provide the information needed to close the ponds, or to provide assurances that there is no threat to underlying groundwater. Since the refinery is underlain by coarse grained sediments, soil degradation caused by past disposal practices might constitute a fairly small plume directly underneath the footprint of a disposal pond. The proposed borings, located x- distance away from the ponds, will not address this possibility. REVIEW OF APPROPRIATE CLEANUP TECHNOLOGIES Each alternative was evaluated individually, and then compared with other alternatives against the set of evaluation criteria developed by the EPA under CERCLA, and the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). The evaluation criteria are: l. Overall protection of human health and the environment 2. Long term effectiveness and permanence 3. Reaction of society, mobility, or volume through treatment 4. Short-term effectiveness 5. Implementability 6. Cost 7. State acceptance 8. Community acceptance Both the soil vapor extraction system in conjunction with an air sparging system were chosen as preferred treatment technologies. This system has shown a high degree of implementability and effectiveness in remediating sites with both groundwater and soil contamination. Based on the coarse-grained lithology predominant at the site, in addition to the data collected during the 90 day SVES pilot test, the Discharger anticipates that pressure communication and air flow through the subsurface can be induced by soil vapor extraction. The Discharger is proposing to conduct a pilot test for the combined treatment technologies during the month of October. The SVES system will be operated at a flow rate greater than the air sparging injection rate to ensure that the injected air is recovered by the SVES. During the pilot test, the following data collection procedures will be conducted: ~; SU~'NLAND REFINE .~- -4- CORRECTIVE ACTION PL. _N BAKERSFIELD, KERN COUNTY A Measure and record EC, concentrations of dissolved oxygen (DO), carbon dioxide, and BOD at the sparginoJmonitoring points every 30 minutes to assess'system effectiveness and DO propagation. B. Monitor static/dynamic pressure and pressure transmission at the sparging and monitoring points, respectively. C. Monitor depth to groundwater in adjacent monitoring wells. D. Collect groundwater samples from the sparge point and monitoring locations for analyses of speciated TPH and BTEX. SUMMARY' AND CONCLUSIONS 1. The work conducted to evaluate alternatives to remediate affected soil and groundwater to background levels appears appropriate for this phase. 2. Delineation of the lateral extent of groundwater degradation appears complete except to the northwest direction from the west tank farm, while the vertical extent of affected groundwater remains undefined. There is no plan and time schedule to contain and cleanup degraded groundwater; therefore, the Discharger is not in compliance with Tasks 3 & 4 of C&A Order No. 95 -702. 3. It does not appear that the work proposed will provide sufficient information to select an appropriate closure method for the discharge ponds.

Included with the report is a site location map, site maps depicting well locations and system piping layout, a graph of cumulative pounds of hydrocarbons removed versus time, a summary of operational data for the reporting period (Tables 1 through 5), and laboratory analytical reports and chains-of-custody. During the reporting period, all operations were performed in accordance with the requirements outlined in the permit. During the reporting period, approximately 34,835 pounds of hydrocarbons were removed via vapor extraction. Remediation via vapor extraction accounts for a cumulative total of 211,565 pounds of hydrocarbons. During the reporting period, liquid-phase hydrocarbon recovery pumps (Wells MW-7, SVE-MW-9R, MW-16, and SE-VE-42) removed approximately 104.7 gallons of hydrocarbons. The total amount of LPH removed (including hand bailing) since December 1996 is approximately 347,7 gallons. Should you have any questions or need additional information, please do not hesitate to contact either of the undersigned at (805) 230-1266.

Transfer water from Tank 37103 to Tank 74002 via refinery piping, by gravity feed and transfer of the water/oil interface to baker tanks by .hose or vacuum truck. 2. Install a valve in the discharge line of Tank 37103 outside the containment berm in a designated truck loading area. 3. To load the crude oil, place the tanker truck or vacuum truck at the designated loading location. 4. Apply truck brakes. 5. Due to the low TVP measured in Tank 37103, no emission controls are required. Emission controls (i.e. carbon absorption canisters) will be standing by on site if needed. 6. To prevent the potential for nuisance vapors, SECOR will monitor emissions at the loading area at the pump exhaust for LEL and olfactory detection. If monitoring instruments detect 20 percent or greater of the LEL, loading operations will be shut down and emissions from the truck's pump will be treated through carbon canisters connected to the truck's pump. 7. Hook up truck's grounding cables to grounding rod. 8. Connect truck to tank at the discharge line valve using 3-inch hose with camlock fitting. 9. If necessary connect carbon treatment unit to truck vent using 3-inch hose with camlock fitting. 10. Open valves and pump crude oil into the truck with the truck's pump. 11. If a tanker truck is used, open the truck's dome and visually monitor fill levels within the tanker. 12. Monitor for hydrocarbon vapors down wind of the loading truck. If monitoring detects 20 percent or greater of the LEL, loading operations will be shut down to inspect for possible leaks in the transfer system and/or to add emission controls. 13. If needed, outfit the vacuum truck of tanker truck with emission controls (i.e. carbon absorption canisters placed at effluent vent of the truck's pump). 14.

Permit Services Manager - Southern District San Joaquin Valley Unified Air Pollution Control District 2700 "M" Street, Suite 275 Bakersfield, CA 93301-2370 RE: REQUEST FOR PRIORITY PROCESSING APPLICATION FOR ATC - MODIFICATION OF DISTRICT ATC #S-207-37-2 Sunland Refining Corporation / North Tank Farm / Crude Oil Loading Rack 1850 Coffee Road, Bakersfield, California SJVUAPCD Facility ID: S-207 Dear Mr. Goff: SECOR International Incorporated (SECOR), on behalf of World Oil Corp. (WORLD) and Sunland Refining Corporation (Sunland), request priority processing for modifications to the Permit To Operate (PTO) for the existing crude oil loading rack on the North Tank Farm of the Sunland Refinery. The loading rack is permitted to load diesel fuel or fuel oils #2 through #6 as Permit Unit S-207-37-2 (attached) of the PTO for the North Tank Farm. The only modification SECOR requests in the attached application is to include the term "crude oil" to allow the loading of tanker trucks with crude oil currently stored in aboveground storage tank (AST) 37103 in the North Tank Farm. Per the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD) approved protocols for removing AST 37103 from service, crude oil will be transferred via the loading rack to tanker trucks (attached) when the requested permit modifications are approved. This will be a one-time operation to remove crude oil stored in the North Tank Farm. No changes in equipment are proposed. The only change requested is the type of material put through the loading rack. Per recent SJVUAPCD requirements for the proposed transfer, the crude oil in AST 37103 was sampled and tested for true vapor pressure (TVP) at storage temperature. TVP results at one and eight feet into the crude oil were 0.56 psia @ 58 degrees F and 0.59 psia @ 57.4 degrees F, respectively. With a TVP of less than 1.5 psia, vapor control provisions should not be required as long as the cargo tank's previous load consists of similar materials, such as crude oil, diesel, or fuel oils #2 through #6. Priority processing is requested to expedite the removal of petroleum from AST 37103 so the tank can be cleaned and removed from service in compliance with the stipulations and deadlines of the Final Judgment between WORLD and the SJVUAPCD and the Kern County District Attorney. Mr. Tom Goff- SJVUAPCD Sunland Refinery / Loading Rack January 19, 1998 Page 2 Due to the high cost of installing monitoring equipment for a tank with no commercial use at this time, WORLD has elected to empty, clean, and remove the AST from service by the March 1, 1998 deadline. Failure to meet this deadline could result in additional punitive actions by the District Attorney and additional costs to WORLD. To complete cleaning activities the crude oil must be removed by the end of January 1998. , Protocols for crude oil removal and laboratory data documenting the true vapor pressure and Reid vapor pressure of the crude oil in AST 37103 are attached. This information has previously been sent to Mr. Jon Adams of the SJVUAPCD regarding decommissioning the floating roof ASTs in the North Tank Farm. Also included is a check for $60.00 for the application fee. Thank you for your prompt attention to this matter and in facilitating WORLD's efforts to meet SJVUAPCD requirements at the North Tank Farm.

ATION LOCATION: 1850 COIa'q::'EE RD, BAKEI~SFI~-.D SUNLAND REFINING CORPORATION North Tank Farm PROTOCOL No. 1 Loading Rack Protocol for Crude Oil Transfer AST 37103 The following protocol will be followed in the draining and loading of crude oil from tank 37103 to the loading rack for transfer to trucks: 1. Transfer water from Tank 37103 to Tank 74002 via refinery piping, by gravity feed. 2. Blind all other ASTs piping to isolate the loading rack vapor-recovery system on AST 37103. 3. Due to the low TVP and Reid vapor pressure (RVP) measured in Tank 37103, no emission controls (i.e. carbon absorption canisters) is required. 4. To prevent the potential for nuisance vapors, SECOR will monitor emissions at the loading rack for LEL and olfactory detection. If monitoring detects 20 percent or greater of the LEL, loading operations will be shut down and emissions from the loading rack will be treated through carbon canisters connected to the vent location. 5. If needed, outfit the existing loading rack with emission controls (i.e. carbon absorption canisters placed at effluent vent of the vapor recovery compressor). 6. Place truck at loading location at the loading rack. 7. Apply truck brakes. 8. Connect truck to loading rack via the bottom loading system with vapor recovery. 9. Open valves. Fill truck at a slow pumping rate (~A - 1 hour) to prevent excessive vapors. 10. Verify that truck and rack have sufficient venting protection. Check that pressure gauge and venting compressor are operational. 11. Fill the truck using loading rack pump. 12. Continue to monitor for hydrocarbon vapors down wind of emission controls. If monitoring detects 20 percent or greater of the LEL, loading operations will be shut down to inspect for possible leaks in the vapor recovery system and/or to remove spent carbon. 13. Upon completion, close valves and disconnect hoses. 14. Transport crude oil offsite for sale. 15. Maintain a log sheet showing a summary of crude oil removed from site including: · Start and finish gauge readings · Temperature · Tank number · Date and time of transfer loll Analytical ~ Consulcin9 Services 4309 Armour Avenue (805) 395-0539 Bakersfield, California 93308 FAX (805) 395-3069 Secor Laboratory No: 71631-10 2190 Conejo Ridge Ave Ste 200 Date Received: 12/23/97 Thousand Oaks, CA 91360 Date Reported: 01/07/98 Contract No.: Attention: Phil Kinney Date Sampled: '12/23/97 Time Sampled: 15:05 Sample Type: Oil/Petrcleum Sample Description: Tank 37103 @ 1' Sampled by S.

Each well was located and inspected upon arrival at the site. Using a SolinstTM Water Level Meter and/or an oil/water interface probe, each well was then gauged for depth to groundwater, depth to floating product (if present) and total well depth. Gauging devices were decontaminated between each well using a triple-rinse method of tap water and non-phosphate detergent, tap water, and then deionized water. Wells were also gauged in expected order of increasing hydrocarbon concentrations to prevent cross-contamination. The sampling sequence was based on the analytical results obtained during the previous quarters sampling event. Groundwater Purging. Each well was purged following gauging. At least three casing volumes of groundwater was removed from each well using a PVC bailer. During purging, water parameters including pH, temperature, conductivity, and turbidity were monitored to calculate stabilization within 10% of each parameter and ensure that groundwater, representative of the aquifer, was entering the well. The bailer was decontaminated between each well using a triple-rinse method of tap water and non-phosphate detergent, tap water, and then deionized water. Wells were also purged in expected order of increasing hydrocarbon concentrations to prevent cross-contamination. Groundwater Sampling. After purging, wells were allowed to recharge to at least 80% of their original capacity prior to sampling. Groundwater samples were collected using a polyethylene disposable bailer attached to clean string. Samples were decanted into containers provided by the laboratory appropriate to the analysis to be performed. The containers were capped with TeflonTM septa, labeled, and placed on ice for transport to State-certified American Analytics Laboratory, in Chatsworth, California. New sampling equipment (string, bailer, etc.) was used on each well to eliminate the possibility of cross-contamination. A quality control sample was collected and submitted with the groundwater samples to the laboratory. A trip blank, provided by the laboratory, was kept in the sample cooler with the collected groundwater samples and handled similarly. SECOR initiated a Chain-of-Custody Record in the field immediately following sample collection to accompany the samples to the laboratory. Product Removal. Product Removal was conducted from wells MW-7, MW-9, MW-16, and MW-42, using the automated liquid petroleum hydrocarbon (LPH) recovery system. Removed product is stored in a poly-tank for later transport to a recycling facility. Currently only wells MW-7 and MW-42 are online due to the low product thickness in the other wells. Waste Disposition. Purge water generated during this monitoring event was stored on-site in labeled and sealed 55-gallon drums. Purge water drums were stored on pallets in a secured area of the South Tank Farm pending off-site recycling. Purge water was trucked to DeMenno/Kerdoon in Compton for recycling. Bailed product is currently stored onsite awaiting proper disposal. Waste recycling/disposal documentation will be provided to the RWQCB upon receipt.

Task 7 of the CAO requires the submittal of a "report of work accomplished to contain and cleanup contaminants in ground water" January 1 and June 1 of each year until cleanup is completed. During the period from June 1, through December 31, 1997, Operation and Maintenance of soil vapor extraction (SVE) and air sparging (AS) systems located at both the former South and West Tank Farms was conducted. In addition, during September 1997, a liquid-phase hydrocarbon (LPH) recovery system was installed at the West Tank Farm. Operation of the LPH system is ongoing. Hydrocarbon recovery data for each of the remediation systems located at the site is provided below and in the quarterly reports. During the reporting period, the SVE systems operating at the South and West Tank Farms removed 65,646 and 43,856 pounds of hydrocarbons, respectively. To date, SVE is responsible for removing 209,580 pounds of hydrocarbons from subsurface soil and groundwater. As presented in SECOR's Corrective Action Plan, dated August 30, 1996, air sparging is also being performed at both the former South and West Tank Farms in conjunction with the soil vapor extraction systems at the site. From August 26 through September 5, 1997, SECOR personnel installed a liquid-phase hydrocarbon (LPH) recovery system at the West Tank Farm. This system replaced hand bailing of LPH from monitoring wells MW-42, MW-9R, MW-7 and MW-16. To date, more than 360 gallons of LPH has been removed by a combination of hand bailing and pumping.

Delivery and installation of the high capacity system will be completed following receipt of the Authority to Construct (ATC). On December 9, 1997, SECOR received a draft copy of the ATC. Following finalization of the draft ATC, system installation bidding, and contractor selection, the system installation is proposed for the First Quarter of 1998. During the reporting period, seven additional SVE wells (SE-VE47, -48, -49, and -50) and AS/SVE nested wells (SE-AS/VE-44, -45, and -46) were installed on the former South Tank Farm (Figure 2). The new remediation wells were installed for later connection by common conveyance piping and manifold to the planned high capacity remediation system. In addition, the wastewater discharge ponds were decommissioned in July through October 1997. SECOR has generated and has submitted a closure report to the CRWQCB entitled: Wastewater Pond Closure Report, dated December 22, 1997.
