(SGI) has prepared this Interim Evaluation and Remediation Progress Report for the former Sunland Refinery property located at 2152 Coffee Road in Bakersfield, California (Figure 1). This Report has been prepared in response to a directive from the Central Valley Regional Water Quality Control Board (RWQCB) within a letter to World dated August 25, 2008 (Appendix A). Within the August 25, 2008 letter, the RWQCB directed World to prepare an Interim Evaluation Report which includes the following: Site geologic data, including updated geologic cross - sections; Laboratory analytical data for soil and groundwater, including isopleth maps of constituents of concern in each hydrostratigraphic unit; Proposed additional investigative work to fully delineate the lateral and vertical extent of groundwater impacted by petroleum hydrocarbons. The RWQCB additionally requested within the August 25, 2008 letter that a "more extensive Remediation Progress Report" be prepared which includes the following: • Changes in hydrocarbon product type and concentrations in soil and groundwater relative to the initiation of remediation efforts and over the last two years; • Amount and type of hydrocarbon product remaining in the subsurface including floating product on the water table; • Hydrocarbon vapor concentrations from individual wells and the High Capacity Vapor Extraction System influent over time; • Graphical data presentations, such as isopleth concentration contours on plan view maps and cross sections depicting changes over time in the distribution of petroleum hydrocarbons; • An evaluation of the impacts of recent fluctuations in groundwater table elevations on remedial efforts; • Analysis and conclusions to support recommendations regarding changes to or why no changes to the remedial efforts are warranted; and • An updated estimate as to the time required under currently known conditions to complete remediation at the site. This Report incorporates the requested information for both the Interim Evaluation Report and the more extensive Remediation Progress Report. Pertinent historical site data, up to and including the first half 2008 semi - annual groundwater monitoring event, is presented and discussed herein. The Source Group, Inc. Mr. Russell W. Walls, CVRWQCB November 28, 2008 Interim Evaluation and Remediation Progress Report Page 2 Former Sunland Refinery 2.0 SITE INFORMATION 2.1 SITE HISTORY The former Sunland Refinery was built in 1923 and bought by Sunland Refining Corporation in 1944. In 1978, World Oil Corp. purchased the Sunland Refining Corporation. While operational, the Sunland Refinery had a rated capacity of approximately 15 million barrels per day. The Sunland Refinery ceased refining operations in 1995. Refinery infrastructure was removed between 1995 and 1999. The former Sunland Refinery was subdivided into three main areas: the former Refinery /South Tank Farm (STF); the former West Tank Farm (WTF); and the former North Tank Farm (NTF) (Figure 2). The former refinery area designations continue to be used by World as reference to site locations, even though all refinery infrastructure has been removed.' The former Refinery/STF is located west of Old Coffee Road and south of the Atchison Topeka and Santa Fe (ATSF) Railroad. This area is approximately 20 acres in size and formerly housed the main petroleum refining operations and thirty eight above ground storage tanks (ASTs) within the STF. Products stored within the former STF included crude oil, fuel oil, gasoline, diesel, and slop oil. The former West Tank Farm (WTF) is located west of Old Coffee Road, east of the new Coffee Road overpass, and south of the ATSF Railroad. This area encompasses approximately 4.7 acres and historically contained seven ASTs which stored gasoline, diesel, and stove oil. The former WTF area is currently occupied by Pan Pacific Petroleum, a hydrocarbon products transportation company. The former NTF is located east of Old Coffee Road and north of the ATSF Railroad. This area encompasses approximately 21 acres and contained 13 AST, which stored crude oil, gasoline, and diesel. Average site elevation is approximately 385 feet above mean sea level (AMSL). 2.2 REMEDIATION HISTORY Remedial activities have been conducted at the site since March of 1996, and have consisted of the following: • Soil vapor extraction to remove volatile hydrocarbon constituents within source area soils (i.e. reduce the potential for migration of constituents to underlying groundwater); • Air sparging to both strip volatile hydrocarbons from groundwater as well as promote aerobic biodegradation of organic constituents; • Liquid petroleum hydrocarbon (LPH) removal, via pneumatic pumps, vacuum extraction, and bailing to mitigate LPH as a source for continued groundwater impact; and • Natural attenuation monitoring of hydrocarbon constituents beneath and downgradient of the site. Soil vapor extraction (SVE) was initiated at the site in March of 1996 to remove volatile organic constituents (VOCs) from the vadose zone. Two Paragon thermal oxidizers were installed at The Source Group, Inc. Mr. Russell W. Walls, CVRWQCB Interim Evaluation and Remediation Progress Report Former Sunland Refinery November 28, 2008 Page 3 the site, one unit at the former WTF and a second unit within the former Refinery/STF. The Paragon units were installed to conduct SVE pilot testing and to serve as an interim remedial measure, while a High Capacity Vapor Extraction System (HCVES) was designed and constructed. Construction of the HCVES was completed within the STF remediation compound in September 1998. The HCVES utilized two 500 standard cubic feet per minute (scfm) Studerbuilt blowers and a John Zinc candle flare for vapor conveyance and abatement. The John Zinc flare was operated as the primary abatement device from September 1998 to May 2005. In May 2005, a high capacity Baker Furnace thermal oxidizer was installed at the STF remediation compound to replace the flare as the primary abatement device. The Baker oxidizer was installed in response to decreasing system influent concentrations as remediation at the site proceeded. The Baker unit, which can also be operated in catalytic mode, allows for more efficient system operation at relatively lower influent concentrations. Modifications to the HCVES Permit to Operate (PTO) were requested by World and approved by the San Joaquin Air Pollution Control District (SJAPCD) to allow the flare to remain as a back -up abatement device. Depending upon system operating parameters (principally system influent concentrations), the HCVES can be operated in flare mode, thermal oxidizer mode, or catalytic mode under the current PTO. Air sparging was initiated at the site beginning in December 1996 within the objective of 1) stripping volatile hydrocarbon constituents from groundwater and 2) promoting aerobic biodegradation of petroleum hydrocarbons within the subsurface. Currently, two 100 scfm Ingersoll Rand rotary screw air compressors (one installed within the WTF remediation compound and a second at the STF remediation compound) are utilized to inject air into sparge wells installed at the former Refinery/STFM/TF and on downgradient properties. Liquid hydrocarbon product recovery began in September 1997 with the installation of pneumatic product pumps within affected wells. Product recovery has additionally been undertaken at the site by vacuum extraction utilizing the HCVES as well as vacuum trucks and by automated bailing of affected wells. 2.3 REGIONAL GEOLOGY AND HYDROGEOLOGY The former Sunland Refinery is located within the San Joaquin Valley, which constitutes the southern portion of the Great Valley geomorphic province. The Great Valley is a topographic and structural basin bounded on the east by the Sierra Nevada, on the west by the Coast Ranges, and on the south by the Tehachapi and San Emigdio Mountains. The Sierra Nevada is a faulted block dipping gently southwestward and is composed of igneous and metamorphic rocks of pre - Tertiary age, which also comprise the basement complex of the Valley. The Coast Ranges contain folded and faulted sedimentary rocks of Mesozoic and Cenozoic age, which are similar to the rocks that immediately underlie the Valley and noncomformably overlie the basement complex. The topography of the San Joaquin Valley floor is nearly flat with slight northerly slope that has developed upon alluvial fan, lake bed, and stream channel deposits. The elevation ranges from sea level in the north part of the San Joaquin Valley to about 500 feet above seal level in the southern areas. The Source Group, Inc. Mr. Russell W. Walls, CVRWQCB November 28, 2008 Interim Evaluation and Remediation Progress Report Page 4 Former Sunland Refinery The major structural feature in the area of the site is the Bakersfield Arch. The Bakersfield Arch is an approximate east -west trending fold in the Bakersfield - Fruitvale area that is generally believed to be the cause for the thinner section of Tertiary age sediments in the middle of the southern San Joaquin Valley, north of Bakersfield and the east -west trending fold. The sedimentary section in the Bakersfield- Fruitvale area has been the object of numerous investigations related to the recovery of oil and natural gas, and the State of California Division of Oil and Gas (DOG) estimates the thickness of these sediments to be 8,500 to 11,570 feet thick. The total post- Tertiary sedimentary sequence in the San Joaquin Valley south of the Bakersfield Arch is locally up to 35,000 feet thick (Page 1986). In the Bakersfield area, Sierran basement rocks are overlain by Early to Middle Tertiary-age marine sedimentary rocks. These marine sediments are overlain by poorly consolidated continental sediments that typically contain the regional groundwater reservoirs. The continental sediments consist of alluvial fan, fluvial, and minor lacustrine deposits associated with deposition by the Kern River. These continental deposits reportedly reach an average depth of approximately 2,000 feet below ground surface (bgs) in the area of the site (Page 1986). Hydrologically, the former Sunland Refinery is located within the Kern County subbasin of the San Joaquin Valley Groundwater Basin of the Tulare Lake Hydrologic Region. The Tulare Lake Hydrologic Region covers roughly one -third of the Great Valley and within this area, a total of 13 groundwater basins and areas of potential storage have been identified (California's Groundwater, Bulletin 118, 2003). Within the Kern County subbasin, the Kern River flows in a southwesterly direction and provides significant recharge to the local groundwater system. At its closest point, the Kern River is approximately 4,000 feet south of the site. Recharge to the underlying regional aquifer (encountered beneath the site at approximately 55 to 120 feet bgs) is regulated by the Kern County Water Agency. Recharge in the vicinity of the site is a combination of both artificial and natural recharge from the Kern River south of the site. Due to the recharge by the Kern River, groundwater movement is generally to the northwest across the site. Water- bearing sediments beneath the site consist of Late Tertiary and Quaternary-age sand and gravel sediments of Sierran origin which were deposited by the Kern River. 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, low energy deposits of silt, fine sand and clay are generally encountered below 600 to 800 feet bgs and data from the Flying J Refinery east of the site suggests that a regional aquitard begins at a depth of approximately 250 feet. 2.4 SITE GEOLOGY The former Sunland Refinery is located on the eastern side of the San Joaquin Valley in close proximity to the Sierra Nevada Range. The upper several hundred feet of the stratigraphic sequence consists of alluvial deposits of the Kern River Formation which primarily include unconsolidated sand layers with secondary gravel, silt, and clay layers of variable thickness and continuity. The Source Group, Inc. Mr. Russell W. Walls, CVRWQCB November 28, 2008 Interim Evaluation and Remediation Progress Report Page 5 Former Sunland Refinery The geology beneath the site is illustrated on cross sections A -A' through D -D' which are provided on Figures 4 and 5. As shown on the cross section index map Figure 3, these cross sections provide one northwest- southeast transect (i.e. A -A'), one south -north transect (i.e. B- B'), and two southwest - nort heast transects (i.e. C -C' and D -D') as follows: Northwest- southeast trending Cross Section A -A' (Figure 5) begins west of the western PG &E property line near nested well cluster TSG- MW- 115A/B/C, trends southeast across the PG &E property before crossing the Atchison Topeka and Santa Fe Railroad (AT &SF RR) easement and "new" Coffee Road into the northern portion of the former West Tank Farm, crosses "old" Coffee Road and through the former South Tank Farm, and terminates east of the former Sunland Refinery properly line near well MW- 10(R). This cross section is generally parallel with the northwesterly groundwater flow direction identified in the shallow aquifer beneath the site; South -north trending Cross Section B -B' (Figure 5) begins in the undeveloped farmland west of the former Sunland Refinery near nested well cluster TSG- MW- 1 16A/B /C, trends north across the AT &SF RR easement into the PG &E property, crosses through nested well cluster TSG- MW- 1 15A/B/C, and terminates within the PG &E property near nested well cluster TSG- MW- 1 14A/B /C. This cross section shows soil and groundwater conditions in the vicinity of the furthest downgradient wells installed to date; • Southwest - northeast Cross Section C -C' (Figure 6) begins in the undeveloped farmland west of the former Sunland Refinery near well SE- MW -26, trends northeast across the AT &SF RR easement into the PG &E property, crosses through nested well clusters GMX- MW- 62S /D, TSG- MW- 83A/B /C, and TSG- MW- 84A/B /C, and terminates near the PG &E property tank farm near well GMX- MW -61; and Southwest - northeast Cross Section D -D' (Figure 6) begins in the southern part of the former West Tank Farm near well MW -19, trends northeast across the AT &SF RR and old Coffee Road into the former North Tank Farm near well TSG- MW -72, and terminates in the northern -most part of the former North Tank Farm near well MW -3. Both C -C' and D -D' are oriented roughly perpendicular to the northwest groundwater flow direction in the shallow aquifer beneath the site. Review of the above cross sections indicate that the lithology beneath the site consists primarily of alternating layers of poorly- to well - graded sand, gravely sand, and silty sand, with lesser amounts of sandy silt, silt, and clay to the maximum explored depth of approximately 212 feet bgs. Most of the fine grained sediments are discontinuous, however relatively continuous fine - grained strata is evident in the northwest - southeast direction at approximately 90 and 120 feet bgs (Cross Section A -A'). Cross Sections B -B' through D -D' suggest that these find - grained zones are present to the south of the site (i.e. toward the Kern River) and pinch out to the north. 2.5 SITE HYDROGEOLOGY The shallow groundwater aquifer beneath the site is unconfined and resides within Recent unconsolidated sands and silts deposited by the Kern River. Significant fluctuation in the water table elevation underlying the site has historically occurred, attributed to variation in recharge conditions at the Kern River south of the site. The water table has been encountered as shallow The Source Group, Inc. Mr. Russell W. Walls, CVRWQCB November 28, 2008 Interim Evaluation and Remediation Progress Report Page 6 Former Sunland Refinery as 55 to 60 feet below ground surface (bgs) to as deep as approximately 120 feet bgs underlying the site from the inception of recurring groundwater monitoring (March 1996) through the present. Graph 1 presents hydrographs depicting water -table elevations versus time within select groundwater monitoring wells from March 1996 (initiation of regular groundwater monitoring) through March 2008. The shallow groundwater underlying the site (less than 250 feet deep) has been divided into three shallow hydrostratigraphic zones for ongoing groundwater assessment purposes. Groundwater zones have been defined underlying the site based on depth within the aquifer in order to assess constituents of concern at discrete depths within the aquifer. The Shallow Hydrostratigraphic Zone 1A (SHZ 1A) is defined as the zone in which the unconfined water table resides, and incorporates groundwater monitoring wells screened to accommodate the fluctuating water table beneath the site. Depending upon recharge conditions related to the Kern River flow, historic water table elevations have been encountered as shallow as 55 feet bgs to as deep as 120 feet bgs beneath the site. Currently, SHZ 1A is monitored by wells screened from approximately 70 feet to 115 feet bgs. Shallow Hydrostratigraphic Zone 1 B (SHZ 1 B) is identified and monitored by wells which are screened between 115 and 184 feet bgs. Shallow Hydrostratigraphic Zone 1 C is identified and monitored by wells which are screened between 192 feet bgs and 212 feet bgs. During the March 2008 gauging and sampling event, the depth to the unconfined water table beneath the site was encountered between 95.80 feet and 112.19 feet bgs (292.80 to 273.87 feet above mean sea level). The groundwater gradient across the site in March 2008 was approximately 0.005 foot/foot ( ft/ft). Figure 6 presents the potentiometric surface map for the Shallow Hydrostratigraphic Zone 1A in March of 2008. The direction of groundwater flow beneath the site and site vicinity is to the west - northwest (away from the Kern River). A consistent west - northwesterly SHZ 1A groundwater flow direction underlying the site and site vicinity has been documented over the last 12 years of groundwater monitoring. The calculated groundwater gradient across the site has historically ranged from approximately 0.005 ft/ft to 0.01 ft/ft. Potentiometric surface elevation maps for the March 2008 time period depicting the potentiometric surface for SHZ 1 B and SHZ 1 C are included as Figures 7 and 8, respectively. Groundwater flow direction within both the SHZ 1 B and SHZ 1 C is to the west - northwest similar to SHZ 1A. The horizontal gradients for the SHZ 1 B and SHZ 1 C potentiometric surface are calculated as 0.008 ft/ft and 0.003 ft/ft, respectively, which are similar to historical horizontal gradients measured for the SHZ 1A. A general downward gradient was observed between the three hydrostratigraphic zones during the March 2008 groundwater monitoring event (Table 1). An average downward gradient of 0.142 ft/ft was calculated between SHZ 1A and SHZ 1B. An average downward gradient of 0.056 ft/ft was calculated between SHZ 1 B and SHZ 1 C. An average downward gradient of 0.130 ft/ft was calculated between SHZ 1A and SHZ 1C. Localized fine grained silt and silty sand interbeds occur within the predominantly sandy sediments encountered beneath the site and vicinity. These finer grained zones are generally believed to be laterally discontinuous, based on the lithologic logging (Figures 4 and 5). However, hydraulic confinement may occur locally in portions of the site. Based on the similarity of the hydrologic characteristics within the three identified hydrostratigraphic zones, the three zone are considered to be in general hydrologic connection, with some potential for localized confinement. The Source Group, Inc. Mr. Russell W. Walls, CVRWQCB Interim Evaluation and Remediation Progress Report Former Sunland Refinery November 28, 2008 Page 7 Aquifer testing conducted by ENSR in December of 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). Based on the dates of testing, aquifer parameters measured by ENSR represent conditions within SHZ 1A. The Source Croup, Inc. Mr. Russell W. Walls, CVRWQCB November 28, 2008 Interim Evaluation and Remediation Progress Report Page 8 Former Sunland Refinery 3.0 ASSESSMENT OF IMPACTS The source of hydrocarbon impact to soil and groundwater underlying the former Sunland Refinery is related to historic releases of petroleum products originating from above ground storage tanks, pipelines, and refinery infrastructure during the approximate 70 year operational history of the facility. As the refinery ceased operation in 1995, and all refinery infrastructure was removed between 1995 and 1999, on -site sources for continued release of petroleum constituents no longer exist. Based on the assessment data collected to date, the majority of hydrocarbon soil impact resides beneath the area of the former Refinery, former STF and former WTF (former facilities located south of the ATSF Railroad). The former North Tank Farm (located north of the ATSF Railroad) was constructed in the 1970's, and is therefore much younger than the refinery facilities on the south side of the ATSF Railroad line (Figure 2). Significant impact to soil underlying the North Tank Farm has not been encountered. Hydrocarbon constituents within soil have reached the unconfined aquifer beneath the former Refinery site. As discussed previously, depth to groundwater beneath the site has ranged from approximately 55 feet bgs to 120 feet bgs. Hydrocarbon constituents, including total extractable petroleum hydrocarbons (TEPH), total petroleum hydrocarbons as gasoline (TPHg), aromatic hydrocarbons including benzene, and the fuel oxygenate methyl tertiary butyl ether (MtBE) have been detected as dissolved -phase constituents in groundwater underlying the site. In addition, liquid phase hydrocarbons (LPH) predominately in the gasoline range are present at the groundwater interface within areas underlying the former Refinery/STFM/TF facilities. Dissolved phase TEPH, TPHg, benzene, and MtBE are present in groundwater downgradient (west - northwest) of the former Refinery area. Hydrocarbon constituents have been detected within the furthest downgradient monitoring well TGS -MW -115, which is approximately 2,900 feet from the contaminant source area (the main Refinery/STF area). Assessment of impacts has been completed through the advancement of soil borings, the installation of groundwater monitoring wells, soil vapor sampling, and groundwater sampling. 3.1 SUMMARY OF SOIL ANALYTICAL DATA Analytical data for soil has been collected during numerous previous site assessment and remediation efforts conducted at the site. A majority of the soil assessment data was collected during the installation of groundwater monitoring wells and remediation wells, both on and off the site. Within the former Refinery/STF, and former WTF area (core of the hydrocarbon plume), approximately 67 wells /boreholes have been advanced for characterization /assessment and well installation purposes. Historical soil analytical tables, which characterize soil conditions at the time the samples were collected, are included within Appendix B. With the significant remediation efforts that have occurred over the last 12 years (i.e. the significant mass of VOCs that have been removed from the vadose zone via SVE), isopleth maps based on historic soil data are not believed relevant to current conditions. Soil analytical data is The Source Group, Inc. Mr. Russell W. Walls, CVRWQCB November 28, 2008 Interim Evaluation and Remediation Progress Report Page 9 Former Sunland Refinery used to identify zones of impact within the source area and aid in the placement of remediation and monitoring wells. Progress toward vadose zone (soil) cleanup is assessed by collecting soil vapor samples from individual remediation wells within and proximal to the identified source areas. Soil vapor isopleth maps have therefore been prepared to assess current conditions beneath the site and are discussed in greater detail below. 3.2 SUMMARY OF SOIL VAPOR ANALYTICAL DATA Isopleth maps depicting VOC concentrations within three depth- discrete soil vapor extraction zones are included as Figures 9 through 17. The vadose zone underlying the site is divided into three equal 40 -foot thick depth intervals to accommodate vacuum extraction across the roughly 120 -foot thick unsaturated zone. Soil vapor extraction wells, the majority of which consist of nested casings with multiple screen zone depths, were installed to allow focused SVE within portions of the three depth- discrete zones. Included isopleth maps depict VOC influent concentrations from the Upper Vadose Zone (UVZ) [near surface to 40 feet bgs], the Intermediate Vadose Zone (IVZ) [40 feet to 80 feet bgs], and the Lower Vadose Zone (LVZ) [80 feet to 120 feet bgs]. Vapor isopleth maps were additionally contoured for three time periods (March 1999, March 2002, and January 2008) to illustrate variation in hydrocarbon vapor concentrations within individual depth zones and areas of the site over time. Soil vapor extraction within the Lower Vadose Zone is affected by groundwater fluctuations beneath the site. As discussed previously, the water table surface elevation has fluctuated as much as 50 feet underlying the site during the last 12 years of monitoring. During periods of groundwater rise, the Lower Vadose Zone becomes partially or completely saturated, restricting SVE. During periods of highest groundwater levels, the IVZ may also become partially saturated, similarly affecting SVE operations. Vapor extraction system influent concentrations, (i.e. Tedlar bag samples analyzed by a State - certified analytical laboratory) are plotted vs. time on Graph 2. A hydrograph plot for well SE- MW -23(S) (source area well) is additionally imposed on Graph 2 to illustrate the association between changes in groundwater elevation and corresponding changes in SVE influent concentration. During periods of high groundwater elevation, the LVZ and portions of the IVZ become saturated, restricting these zones from SVE and affecting a corresponding decrease in SVE influent concentrations to the remediation system. As groundwater levels decrease, a corresponding increase in SVE influent concentrations typically occurs. As the majority of hydrocarbon mass removal is achieved via SVE, monthly and /or yearly mass removal can decrease substantially during periods of high groundwater. Vapor concentrations are collected from individual remediation well casings on a periodic basis (typically monthly to bimonthly) to allow for optimization of the HCVES system as well as to assess progress toward vadose zone cleanup. Vapor concentrations from individual SVE well casings are collected via a sampling port installed within each well casing at the well head manifold and analyzed in the field using a Horiba hydrocarbon gas analyzer. Graphical representation of individual well influent concentrations for selected SVE wells over time are included within Appendix C. 3.2.1 Upper Vadose Zone Figures 9 through 11 depict VOC concentrations within the Upper Vadose Zone (near surface to 40 feet) over three time periods (March 1999, March 2002, and January 2008). A significant The Source Group, Inc. Mr. Russell W. Walls, CVRWQCB November 28, 2008 Interim Evaluation and Remediation Progress Report Page 10 Former Sunland Refinery reduction in VOC concentrations is evident within the UVZ over the period March 1999 through January 2008 as a result of SVE operations. In March of 1999, VOC concentrations greater than 1,000 part per million by volume were present over the majority of the former Refinery and STF area, as well as a significant portion of the former West Tank Farm Area. By January of 2008, the majority of UVZ wells contained VOC concentrations in the low hundreds of parts per million by volume or less. Graphs depicting influent VOC vapor concentrations over time within select UVZ SVE wells are included within Appendix C. Within the majority of UVZ wells, influent concentration trend lines show a general decrease in VOC influent concentrations with time, in response to ongoing SVE. During current SVE operations select wells screened within the UVZ continue to be operated to encourage air movement through the UVZ and promote further aerobic degradation of remaining hydrocarbons in this zone. 3.2.2 Intermediate Vadose Zone Figures 12 through 14 depict VOC concentrations within the Intermediate Vadose Zone (40 feet to 80 feet bgs) over the time period March 1999 through January 2008. Similar to the UVZ, significant VOC mass reduction has occurred within the IVZ. In March 1999 and March 2002, VOC concentrations within IVZ wells were greater than 1,000 ppmv over the majority of the former Refinery/STFNVTF areas. A significant reduction in vapor concentration within source area IVZ wells has been achieved as of January 2008 as a result of SVE operation. Graphs depicting influent VOC vapor concentration reduction over time within select IVZ source area SVE wells are included within Appendix C. Similar to UVZ wells, influent concentration trend lines for wells screened within the IVZ depict a reduction in VOC concentrations with time. The IVZ continues to be a primary target zone for continued SVE. Based upon individual well sampling, the well field operational configuration is adjusted monthly to bimonthly to maximize hydrocarbon mass removal within this zone. 3.2.3 Lower Vadose Zone Figures 15 through 17 depict VOC concentrations within the Lower Vadose Zone (80 feet to 120 feet bgs) over the time period March 1999 through January 2008. VOC concentrations detected within LVZ wells during the March 1999 sampling period ranged from 1,020 ppmv to 5,600 ppmv within the plume core. In March of 2002, VOC concentrations within the plume core were significantly greater, ranging from 10,200 ppmv to 32,000 ppmv. Increased VOC vapor concentrations within the LVZ wells in March 2002 relative to 1999 is primarily attributed to a significant decline in groundwater elevation between June 1999 (period of highest groundwater level within the 12 year remedial operations period) and March 2002 (approximate 30 foot drop in groundwater elevation). The groundwater decline allowed for a significantly greater thickness of unsaturated LVZ sediment to be available for SVE. Graphs depicting influent VOC vapor concentrations over time within select LVZ source area SVE wells are included within Appendix C. Groundwater elevation is additionally plotted to illustrate the relationship between groundwater elevation change and influent concentrations within the LVZ wells. The Source Group, Inc. Mr. Russell W. Walls, CVRWQCB November 28, 2008 Interim Evaluation and Remediation Progress Report Page 11 Former Sunland Refinery During periods of groundwater rise, LPH which resides on groundwater and/or is entrained within the fine grained sediments at approximately 90 feet bgs is mobilized upward or "smeared" into previously unsaturated sediments of the LVZ, effectively re- impacting these sediments. Thus when groundwater elevations subsequently decrease and portions of the LVZ again become available to SVE, higher influent VOC concentrations are typically achieved within LVZ wells. The LVZ is a primary target zone of ongoing SVE within the former Refinery /STF and WTF areas. Vapor concentrations within LVZ wells in January 2008 were generally lower than concentrations detected within March of 2002; however, groundwater has continued to decline through 2008 which should increase the mass removal potential from this zone in the future. 3.3 SUMMARY OF GROUNDWATER ANALYTICAL DATA Isopleth maps depicting TPHg, benzene, and MtBE in groundwater within each of the three defined shallow hydrostratigraphic zones are included as Figures 18 through 38. Isopleth maps illustrate constituent plume dimensions for three time intervals (June 1996, March 2002, and March 2008). Concentration contours representing dissolved -phase TPHg, benzene, and MtBE in groundwater for the period March 2008 are graphically depicted on Cross - Section A'A' within Figures 39 through 41, respectively. Only wells which were installed during the period represented by the data are included within the individual isopleth maps. For example, isopleth maps depicting groundwater data for June of 1996, show only the wells that were installed at that point in time. In addition, for the early time period (June 1996), TEPH data are plotted and contoured in lieu of TPHg, as TPHg was not analyzed in groundwater until later sampling events. 3.3.1 Shallow Hydrostratigraphic Zone 1A Shallow Hydrostratigraphic Zone 1A isopleth maps depicting TPH, benzene, and MtBE concentrations in June 1996, March 2002, and March 2008 are included as Figures 18 through 26. Based on the monitoring well network present in June of 1996, TPHg within SHZ 1A was found to extend from the former Refinery/STF source area to beyond monitoring well SE- MW -20S (approximately 1,400 feet to the west of the source area). Benzene is interpreted as having a similar extent to TPHg during the 1996 monitoring period. In March of 2002, TPHg and benzene were detected within SHZ 1A well TSG- MW -67A (approximately 2,900 feet northwest of the source area). However, neither TPHg nor benzene has been detected within well TSG - MW -67A during the last three semi - annual groundwater monitoring events. In March of 2008, TPHg and benzene show an evident reduction in extent and concentration in groundwater within the SHZ 1A. During the March 2008 sampling event, the maximum extent of dissolved phase TPHg within SHZ 1A wells was approximately 600 feet northwest of the source area, within well GMX- MW -60. Benzene was detected in only one SHZ 1A well (MW -19), adjacent to the refinery source area. Currently, dissolved -phase TPHg and benzene with SHZ 1A is laterally defined to the north by wells SE- MW -27, GMX- MW -61, TGS -MW -67A, TSG -MW- 84A; to the west by wells SE- MW -26, TSG- MW -114A; TSG- MW -115A, and TSG- MW -116A; and to the south by wells MW -11, SE- MW -21, and SE- MW -22. The Source Group, Inc. Mr. Russell W. Walls, CVRWQCB November 28, 2008 Interim Evaluation and Remediation Progress Report Page 12 Former Sunland Refinery In June of 1996, monitoring wells sampled for MtBE were generally upgradient of the source area, and did not contain MtBE above method detection limits. Therefore, an assumed dissolved phase MtBE plume is presented within Figure 24. Based on the monitoring well network present in March 2002, MtBE within SHZ 1A was detected within downgradient monitoring wells GMX- MW -60, TSG- MW -71, SE- MW -51, and SE- MW -20S (approximately 900 to 1,200 feet north and west of the source area). During the March 2008 sampling event, MtBE was detected in downgradient wells GMX -MW -60 and MW -13 (approximately 600 feet northwest and 1,000 feet west of the source area, respectively) Constituent concentration vs. time plots (Appendix D) depict a general trend of declining constituent concentrations in groundwater within SHZ 1A wells over time. Dissolved phase TPHg concentrations within the SHZ 1A declined by an order of magnitude within the source area, decreasing from concentrations above 100 mg /L to a high of 18 mg /L in March of 2008. Similarly, benzene concentrations declined within the plume core from a high of 41 mg /L to 0.0028 mg /L (well MW -19). The decline in constituent concentrations within SHZ 1A is attributed to ongoing remedial activities including air sparging which has been effective in stripping volatile constituents from groundwater as well as promoting aerobic biodegradation within the subsurface. 3.3.2 Shallow Hydrostratigraphic Zone 1 B Shallow Hydrostratigraphic Zone 1B isopleth maps depicting TPH, benzene, and MtBE concentrations in June 1996, March 2002, and March 2008 are included as Figures 27 through 35. Based on the monitoring well network present in June of 1996, TPHg and benzene within SHZ 1 B were found to extend from the former Refinery/STF source area to monitoring well SE -MW- 20D (approximately 1,400 feet to the west - northwest of the source area). In March of 2002, TPHg and benzene were detected within SHZ 1B wells GMX- MW -62D and TSG- MW -67B /C (approximately 2,900 feet northwest of the source area). In March of 2008, TPHg was detected within SHZ 1B well TSG- MW -115B, located approximately 2,900 feet west - northwest of the source area. Benzene was not detected above method detection limits in SHZ 1B wells during the March 2008 sampling event. Based on the current monitoring well network, dissolved - phase TPHg and benzene within SHZ 1B are laterally defined to the north by wells TSG -MW- 82A, TSG- MW -84B, TSG- 85A/B, TSGOMW -67B, and TSG -MW -1146; and laterally defined to the south by well TSG- MW -116B. Based on the monitoring well network present in June of 1996, MtBE within SHZ 1B was detected within monitoring well SE- MW -20D (approximately 1,400 feet to the west - northwest of the source area). In March of 2002, MtBE was detected within SHZ 1B wells GMX -MW -62D and TSG -MW -67B /C (approximately 2,900 feet northwest of the source area). However, MtBE has not been detected within well TSG -MW -67B /C for a period of approximately 5 years. In March of 2008, MtBE was detected within SHZ 1 B well TSG -MW -1156, located approximately 2,900 feet west - northwest of the source area. Similar to TPHg and benzene, dissolved -phase MtBE within SHZ 1 B is laterally defined to the north by wells TSG- MW -82A, TSG- 85A/B, TSG - MW -67B, and TSG -MW -11413; and to the south by well TSG- MW -116B. The Source Group, Inc. Mr. Russell W. Walls, CVRWQCB November 28, 2008 Interim Evaluation and Remediation Progress Report Page 13 Former Sunland Refinery 3.3.3 Shallow Hydrostratigraphic Zone 1C Shallow Hydrostratigraphic Zone 1C isopleth maps depicting TPHg, benzene, and MtBE concentrations in March 2008 are included as Figures 36 through 38. Wells screened within the SHZ 1 C were not installed during either the June 1996 or the March 2002 sampling event, therefore, isopleth maps relating to SHZ 1C were prepared only for the March 2008 sampling period. Benzene was detected within the furthest downgradient monitoring well (TSG- MW -115C) at a concentration of 0.002 mg /L during the March 2008 sampling event, slightly above the MCL for benzene of 0.001 mg /L. Well TSG- MW -115C represented the only SHZ 1 C well with a benzene detection during the March 2008 sampling event. TPHg was detected in only one SHZ 1C well (TSG- MW -83B) at a concentration of 0.068 mg /L. MtBE was detected within both TSG -MW- 83B and TSG- MW -115C at a concentration of 0.11 mg /L and 0.0031 mg /L respectively during the March 2008 sampling event. It should be noted that the detected MtBE within SHZ 1 C at the furthest downgradient well is below the established MtBE MCL of 0.005 mg /L. Similar to SHZ 1 B, dissolved -phase MtBE is present in groundwater to the west - northwest of the site within the SHZ 1 C in a relatively narrow configuration. Based on the current monitoring well network, dissolved -phase MtBE within SHZ 1C is laterally defined to the north by wells TSG - MW-84C, TSG -85C, TSG- MW -67C, and TSG- MW -114C; and to the south by well TSG -MW- 116C. 3.4 LIQUID PETROLEUM HYDROCARBON OCCURANCE LPH profiling was conducted in June of 1999 to assess the type of liquid phase hydrocarbon (LPH) occurring beneath the site. The results of the sampling were included within the report entitled Well Installation and LPH Sampling Report (SGI, August 1999). Eight groundwater monitoring and/or remediation wells containing LPH were sampled and analyzed for hydrocarbon speciation (C7 through C30) and MtBE by EPA Method 8260A. All of the wells used for LPH profiling were located within the former Refinery/STF source area or former WTF source area. A summary of LPH analytical results is included as Table 2. Liquid petroleum hydrocarbon residing beneath the former Refinery/STF and former WTF was predominately comprised of light end volatile hydrocarbons within the C7 to C13 range. Lesser amounts of diesel /kerosene range hydrocarbons were additionally present. MtBE was detected in two LPH samples collected from wells SE- ASNE -44 and SE- VE-47, located within the former Refinery/STF area. Thickness of LPH within site wells has historically ranged from tenths of a foot during periods of relatively lower groundwater levels to over 10 feet during periods of relatively higher groundwater levels. As discussed previously, during periods of high groundwater, the LVZ can become completely saturated with water. When this occurs, SVE wells screened within the LVZ become partially or completely submerged, limiting or preventing SVE within this zone. However, during periods of relative higher groundwater elevations, a general increase in the thickness of LPH is observed within select site wells. As depicted with graphical plots included within Appendix E, as groundwater elevation increases, measured LPH thickness generally increases within remediation /monitoring wells located within the source area. The Source Group, Inc. Mr. Russell W. Walls, CVRWQCB November 28, 2008 Interim Evaluation and Remediation Progress Report Page 14 Former Sunland Refinery Greater accumulation of LPH within source area wells during periods of high groundwater is attributed to LPH mobilization as groundwater saturates sediments through which the LPH was smeared during periods of lower groundwater. Silt and sandy silt interbeds at approximately 85 to 95 feet bgs in the source zone are believed to hold LPH during periods of lower groundwater. As recharge conditions change and groundwater begins to rise, these sediments become saturated with water, and LPH is displaced and accumulates at a more rapid pace within site wells. In some instances (see Product Accumulation Graphs for wells MW -5, SE- VE -48C, VE -75, MW- 7) well screens become completely submerged. As LPH mobilizes into wells from zones beneath the water table, the well acts as an oil trap with the potential to accumulate a significant thickness of LPH. Thus, LPH removal through the various methods of collection generally increases during periods of high groundwater. An evaluation of the changes in hydrocarbon product type has not been conducted as recent LPH sampling data is unavailable. Future LPH sampling, to be conducted during the first half 2009 groundwater sampling event, will allow a comparison of historical and current product characteristics. In addition, an estimate of the volume of LPH within the subsurface has not yet been completed. World is reviewing the current LPH data to determine an appropriate interval for calculating a true LPH thickness residing on groundwater as well as accounting for LPH which may reside within fine grained sediments at approximately 85 to 95 feet bgs. The Source Group, Inc. Mr. Russell W. Walls, CVRWQCB November 28, 2008 Interim Evaluation and Remediation Progress Report Page 15 Former Sunland Refinery 4.0 DISCUSSION 4.1 REVIEW OF REMEDIAL PROGRESS As outlined within the Corrective Action Plan (CAP) (SECOR International Incorporated, August 30, 1996), SVE was chosen as a technically sound, time- and cost - effective approach for remediation of the predominately light -end volatile petroleum hydrocarbon constituents present within soil and groundwater underlying the site. To date, the remedial activities conducted at the site have been effective in removing hydrocarbons from the subsurface media and have made significant progress in reducing contaminant concentrations in both soil and groundwater. The following bullets summarize current conditions and remedial progress which has been achieved to date: The lithology beneath the site consists primarily of alternating layers of poorly- to well - graded sand, gravely sand, and silty sand, with lesser amounts of sandy silt, silt, and clay to the maximum explored depth of approximately 212 feet bgs. Most of the fine grained sediments are discontinuous, however relatively continuous fine - grained strata is evident in the northwest - southeast direction at approximately 90 and 120 feet bgs. The shallow groundwater aquifer beneath the site is unconfined and resides within Recent unconsolidated sands and silts deposited by the Kern River. The direction of groundwater flow beneath the site and site vicinity is to the west- northwest (away from the Kern River). A consistent west - northwest groundwater flow direction underlying the site and site vicinity has been documented over the last 12 years of groundwater monitoring. The calculated groundwater gradient across the site has historically ranged from approximately 0.005 ft/ft to 0.01 ft/ft. The shallow groundwater underlying the site (less than 250 feet deep) has been divided into three shallow hydrostratigraphic zones for ongoing groundwater assessment purposes. Groundwater zones have been defined underlying the site based on depth within the aquifer in order to assess constituents of concern at discrete depths within the aquifer. The Shallow Hydrostratigraphic Zone 1A (SHZ 1A) is defined as the zone in which the unconfined water table resides, and incorporates groundwater monitoring wells screened to accommodate the fluctuating water table beneath the site. Depending upon recharge conditions related to the Kern River flow, historic water table elevations have been encountered as shallow as 55 feet bgs to as deep as 120 feet bgs beneath the site. Currently, SHZ 1A is monitored by wells screened from approximately 70 feet to 115 feet bgs. Shallow Hydrostratigraphic Zone 1 B (SHZ 1 B) is identified and monitored by wells which are screened between 115 and 184 feet bgs, Shallow Hydrostratigraphic Zone 1C is identified and monitored by wells which are screened between 192 feet bgs and 212 feet bgs. • Implemented remedial technologies, including soil vapor extraction, air sparging, and LPH extraction, are responsible for the removal of approximately 3,885 tons of petroleum hydrocarbons from the subsurface beneath the site during the period 1996 to the present. The Source Group, Inc. Mr. Russell W. Walls, CVRWQCB Interim Evaluation and Remediation Progress Report Former Sunland Refinery November 28, 2008 Page 16 • Air sparging and concurrent SVE have been effective in reducing the concentration of dissolved phase hydrocarbons in groundwater within the source area underlying the former Refinery /STFNVTF as well as directly downgradient of the site, thus reducing the future potential for hydrocarbons to occur in groundwater downgradient of the site. The lateral extent of dissolved phase TPHg, benzene, and MtBE within SHZ 1A has been defined in all directions by the current groundwater monitoring well network. Dissolved -phase TPHg, benzene, and MtBE are present in groundwater to the west - northwest of the site within SHZ 1B in a relatively narrow configuration. Based on the current monitoring well network, dissolved -phase TPHg and benzene within SHZ 1 B are laterally defined to the north by wells TSG- MW -82A, TSG- MW -84B, TSG- 85A/B, TSGOMW -67B, and TSG -MW -1148; and laterally defined to the south by well TSG -MW- 116B. Similar to TPHg and benzene, dissolved -phase MtBE within SHZ 1B is laterally defined to the north by wells TSG- MW -82A, TSG- 85A/B, TSG -MW -67B, and TSG -MW- 11413; and to the south by well TSG- MW -116B. • Dissolved -phase MtBE is present in groundwater to the west - northwest of the site within SHZ 1C in a relatively narrow configuration. Based on the current monitoring well network, the dissolved -phase MtBE within SHZ IC is laterally defined to the north by wells TSG- MW -84C, TSG -85C, TSG- MW -67C, and TSG- MW -114C; and to the south by well TSG- MW -116C. 4.2 EVALUATION OF REMEDIAL TECHNOLOGIES The current remedial technologies employed at the site continue to be effective in removing hydrocarbon mass beneath the site, as well as reducing dissolved phase hydrocarbon constituents in groundwater downgradient of the site. A major retrofit of the existing HCVES was recently completed to allow more efficient operation of the HCVES system. Remedial objectives for the site include: 1) demonstrate a stable downgradient attenuating edge for constituents of concern in groundwater with a plume dimension that does not threaten downgradient receptor wells; 2) achieve asymptotic vapor conditions within source area SVE wells; and 3) remove free liquid phase hydrocarbons (LPH) from the subsurface to achieve conditions where LPH does not accumulate within source area wells. The current remedial alternatives have been employed to achieve the stated objectives. Additional remedial alternatives, including enhanced aerobic biodegradation (oxygen and/or ozone sparge), are currently being screened to address the presence of MtBE within groundwater downgradient of the site. World will present alternatives to the RWQCB within a future submittal. 4.3 DELINEATION OF CONSTITUENTS OF CONCERN IN GROUNDWATER A workplan will be submitted to the RWQCB outlining the installation of four additional groundwater monitoring wells (TSG- MW- 1 17A/B /C /D) to be installed approximately 1,000 feet to The Source Group, Inc. Mr. Russell W. Walls, CVRWQCB November 28, 2008 Interim Evaluation and Remediation Progress Report Page 17 Former Sunland Refinery the west - northwest of existing monitoring well TSG -MW -115. The wells will be installed within an approximate 5 to 10 foot radius of each other and will be screened at discrete depth intervals within the shallow hydrostratigraphic zones defined previously. The proposed wells will be installed with the objective of defining the lateral as well as vertical extent of hydrocarbon constituents (TPHg, benzene, and MtBE) in groundwater downgradient of the former Sunland Refinery site. Individual well casings will be screened within the SHZ 1A, SHZ 1B, SHZ 1C, as well as at a depth of approximately 250 feet bgs, within what will be termed the Shallow Hydrostratigraphic Zone 1 D (SHZ 1 D). In order to install the above referenced wells, World will attempt to enter into an access agreement with the owner of the property directly west of the former PG &E Kern Steam Plant. If access is granted by the property owner, the well cluster will be installed and the well will be included within future semi - annual groundwater monitoring events. 4.4 TIME REQUIRED TO COMPLETE REMEDIAL ACTIVITES It is estimated that downgradient delineation wells proposed herein can be completed in 2009, if access is granted in a timely manner by the owner of the property west of the PG &E Kern Power Plant. The time required to complete remedial activities at the site is dependent upon a number of factors including the mass of hydrocarbon remaining within the subsurface beneath the site as well as the future performance of currently implemented remedial alternatives as related to changing site conditions (specifically groundwater fluctuation beneath the site). Currently, a formulated time to remedial completion cannot be provided; however, based on past system performance, it is estimated that at least 5 additional years of soil vapor extraction will be necessary to achieve asymptotic VOC concentrations within core area remediation wells. Air sparging and active LPH removal are also estimated to require at least 5 additional years to continue to address dissolved phase constituents in groundwater. Screening of additional remedial alternatives, including enhanced aerobic biodegradation (oxygen and/or ozone sparge) to address the presence of MtBE within groundwater downgradient of the site, will be completed following an assessment of groundwater conditions within the newly proposed downgradient delineation wells. Depending upon the outcome of the screening process, in the event that remedial equipment is required to be installed on the former PG &E facility, World will negotiate an access agreement with PG &E to provide access to the site. A formal timeframe for the implementation of additional remedial alternatives cannot be provided until the technology evaluation is completed. The Source Croup, Inc. Mr. Russell W.

Several results for methyl tertiary butyl ether (MTBE) and benzene exceed their respective Primary and /or Secondary Maximum Contaminant Level for public drinking water supply systems (§ 64444, Title 22, California Code of Regulations). California Environmental Protection Agency pa°a Recvcled Paper Mr. John P. Hundiey, P.G. - 2 - 25 August 2008 Based upon the analytical results of groundwater sampling, the lateral and vertical extent of the petroleum hydrocarbon degradation in groundwater has not yet been adequately defined. Analytical results of groundwater sampling now indicates that the plume extents to depths of at least 200 feet in the areas of wells SE- MW -20D, TSG- MW-83B, and TSG- MW -115C and possibly deeper. In addition, the groundwater degradation extends at least 2,900 feet west northwest (downgradient) of what is anticipated to be the main source area at the former Sunland refinery. With wells TSG- MW -1158 and C located approximately 115 feet east of the western PG&E property boundary, it appears likely that the plume extends to the northwest, beyond the western PG&E property boundary, and beneath the adjacent property to the west. The remediation system at the site has been in operation since March 1996, a total of 12 years. Reports indicate that as of the end of 2007, the remediation efforts have removed a total of 3,856 tons of petroleum hydrocarbons and 20 tons of MTBE from the subsurface below the former Sunland refinery site. By 10 October 2008, please submit the following to this office: An addendum report addressing specific comments (open bullets) to the reports reviewed in the enclosed Regional Water Board staff memorandum, and A draft fact sheet on the investigative /remedial work completed to date and the findings. World shall also provide to this office a list of parcels, including Assessor Parcel Number (APNs), located within 500 feet of the site; the associated names and addresses of property owners and residents for each parcel, and any other interested parties or groups. For this purpose the "site' refers to properties directly impacted by or which overlie any portion of the known extent of petroleum hydrocarbons in soil or groundwater. Once the draft fact sheet is approved by this office, World shall distribute the fact sheet to the property owners, residents, and other interested parties on the list described above. By 31 October 2008, please submit the following to this office: An interim evaluation monitoring report summarizing the geologic data and laboratory analytical data for analyses of soil and groundwater. This should include, but not be limited to, isopleth maps depicting concentration contours of all constituents of concern in each hydrostratigraphic unit identified and updated geologic cross - sections depicting geology, well construction details, analytical data on soil samples, and groundwater analytical results including isopleth maps depicting concentration contours of all constituents of concern in each hydrostratigraphic unit identified. The report shall provide sufficient detail to be the basis for and shall also propose additional investigative work to fully delineate the lateral and vertical extent of groundwater impacted by petroleum hydrocarbons, and A more extensive remediation progress report that includes, but is not necessarily limited to, changes in hydrocarbon product types and concentrations in soil and groundwater relative to the initiation of remediation efforts and over the last two years; the amount and type of hydrocarbon product(s) remaining in the subsurface including floating product on the water table; hydrocarbon vapor concentrations from individual wells and the high capacity vapor extraction system influent over time; graphical data presentations, such as isopleth concentration contours on plan view maps and cross Mr. John P. Hundley, P.G. - 3 - 25 August 2008 sections, depicting changes over time in the distribution of petroleum hydrocarbons and current conditions; an evaluation of the impacts, both positive and negative, of recent fluctuations in the groundwater table elevation on remediation efforts; sufficient information, analysis and conclusions to support recommendations regarding changes to or why no changes to the remediation efforts are warranted; and an updated estimate as to the time required under currently known conditions to complete remediation of the site. Additional comments are provided in the enclosed Regional Water Board staff review memorandum. We would like to emphasize that the number of comments addressed in the enclosed memorandum involves 10 technical report submittals covering a two -year period. It is not our intent, in preparing this review, to appear to diminish the efforts and accomplishments World has made thus far in recovering approximately 3,876 tons of petroleum hydrocarbon constituents from soil and groundwater. Once World and its consultant have had a chance to review this letter and enclosed memorandum, a meeting to discuss our comments, the general project status, and the future approach to the project may be beneficial. I would suggest this meeting be held prior to the above due dates. We look forward to this meeting and our future discussions. Please contact Daniel Carlson of this office at (559) 444 -2484 if you have any questions regarding this matter or to schedule a meeting. / Y v, VJ,- RUSSELL W. WALLS Senior Engineer.

California Environmental Prolection Agency C4 Recycled Paper Former Sunland Oil Refinery - 2 - 25 August 2008 2006 Semi - Annual Groundwater Monitoring and Status Reports First Half 2006 Semi - Annual Groundwater Monitoring and Status Report Total petroleum hydrocarbons as gasoline (TPHg) concentrations from wells SE -MW- 23S and TSG- MW -113C were the highest reported during the March 2006 sampling event. Groundwater samples collected from wells SE- MW -23S and TSG- MW -113C are reported to have TPHg concentrations of 18,000 and 12,000 micrograms per liter (Ng /L), respectively. The concentration in SE -MW -23S is consistent with historical results. The concentration in TSG- MW -113C is significantly lower than the previous 1,200,000 pg /L reported for the second half of 2005. Neither well had detectable concentrations of methyl tertiary butyl ether (MTBE). • The highest concentration of MTBE, 140 pg /L, was detected in well SE- AS /MW -28D. The second highest concentration of MTBE, 120 pg /L, was detected in well TSG -MW- 83A. This well is approximately 2,000 feet west - northwest (downgradient) of what is anticipated to be the main MTBE source area, the South Tank Farm (STF), at the former Sunland refinery. In our 20 March 2006 review letter regarding the Second Half 2005 Semi - Annual Groundwater Monitoring and Status Report, based upon an analysis of historic MTBE data across the site, Regional Water Quality Control Board (Regional Water Board) staff suggested that the "lagging" benzene associated with a "slug" type MTBE release may have reached its peak concentration in well GMX- MW -62D in September 2005. The results of the current monitoring event indicated that benzene was not detected in well GMX -MW -62D, which appears to confirm that the benzene "slug" in groundwater has now migrated past well GMX -MW -62D. Well GMX -MW -62D is very near well TSG - MW-83A, discussed above, which is approximately 2,000 feet west- northwest (downgradient) of the STF at the former Sunland refinery. Groundwater elevations at the site peaked in September 1999 and then declined until after March 2005 at which time groundwater elevations began to rise. Since March 2005, the elevations rose approximately 15 to 20 feet in wells not in the immediate vicinity of active air sparging and vacuum extraction activities. • The groundwater flow direction during this monitoring event was generally to the northwest at a gradient of approximately 0.010. This is in general agreement with recent monitoring results. Second Half 2006 Semi - Annual Groundwater Monitoring and Status Report TPHg concentrations from wells SE- MW -20S and SE- MW -23D were the highest reported during the October 2006 sampling event. Groundwater samples collected from wells SE- MW -20S and SE -MW -23D are reported to have TPHg concentrations of 5,700 and 16,000 pg /L, respectively. The concentration in SE- MW -20S is consistent with historical results. The concentration in SE -MW -23D is slightly higher than the previous monitoring period, but is significantly lower than most historical results. MTBE Former Sunland Oil Refinery - 3 - 25 August 2008 was detected in well SE- MW -20S at a concentration of 16 pg /L, but was not detected in well TSG- MW -23D. The highest concentration of MTBE, 230 pg /L, was detected in well TSG- MW -83A. The second highest concentration of MTBE, 76 pg /L, was detected in two wells: SE- AS/MW-28(D) and TSG- MW -83B. Wells TSG -MW -83A and B are approximately 2,000 feet west - northwest (downgradient) of what is anticipated to be the main MTBE source area, the STF, at the former Sunland refinery. The results of the subject monitoring event indicated that benzene was again not detected in well GMX- MW -62D, which appears to further confirm that the benzene "slug" in groundwater has now migrated past well GMX -MW -62D. Well GMX -MW -62D is very near well TSG -MW -83A, discussed above, which is approximately 2,000 feet west - northwest (downgradient) of what is anticipated to be the main MTBE source area, the STF, at the former Sunland refinery. • Groundwater elevations at the site peaked in September 1999 and then declined until March 2005 at which time groundwater elevations began to rise. Since March 2005, the elevations continued to rise. Since the previous monitoring report, groundwater elevations rose approximately 5 to 12 feet in wells not in the immediate vicinity of active air sparging and vacuum extraction activities. • The groundwater flow direction during this monitoring event was generally to the northwest at a gradient of approximately 0.012. This in general agreement with historic monitoring results. 2006 Semi - Annual Remediation Progress Reports First Half 2006 Remediation Progress Report • The high capacity vapor extraction system (HCVES) operated approximately 2,440 hours during the reporting period (67 percent of the time). • An estimated 134,310 pounds of hydrocarbons were extracted and destroyed by a thermal oxidizer during the reporting period. This brings the cumulative total of hydrocarbons treated to 7,579,730 pounds since vapor extraction was initiated at the site on 22 March 1996. • An estimated 1,056 pounds of MTBE was extracted and destroyed by the thermal oxidizer during the reporting period. This brings the cumulative total of MTBE treated to 39,158 pounds since October 1996; the earliest date data was available for MTBE. • Approximately 2,070 gallons of liquid petroleum hydrocarbons (LPH) was collected by the HCVES and from affected wells by a vacuum truck. As of the reporting period, the total amount of LPH removed since December 1996 is approximately 10,676 gallons. Former Sunland Oil Refinery - 4 - 25 August 2008 Second Half 20.06 Remediation Progress Report The HCVES operated approximately 2,061 hours during the reporting period (40 percent of the time). • An estimated 57,557 pounds of hydrocarbons were extracted and destroyed by a thermal oxidizer during the reporting period. This brings the cumulative total of hydrocarbons treated to 7,637,287 pounds since vapor extraction was initiated at the site on 22 March 1996. • An estimated 12 pounds of MTBE was extracted and destroyed by the thermal oxidizer during the reporting period. This brings the cumulative total of MTBE treated to 39,170 pounds since October 1996; the earliest date data was available for MTBE. • Approximately 1,180 gallons of LPH was collected by the HCVES and an additional 78 gallons of LPH manually bailed or vacuumed from affected wells by a vacuum truck. As of this reporting period, the total amount of LPH removed since December 1996 is approximately 11,934 gallons. • Operational time during this reporting period was reduced due to conversion of the HCVES from thermal to catalytic mode of operation. The Report indicates the HCVES was off line from 31 July 2006; the catalyst installed in September 20D6; and start-up testing was performed on 4 October 2006 under the supervision of San Joaquin Valley Air Pollution Control District staff. During the conversion, LPH continued to be collected from affected wells. o The language of the text suggests that the HCVES was back online on 4 October 2006. However, Figure 5 of the Report, that includes a graphical display indicating when the. HCVES is operational, suggests it was not back fully operational until about three weeks after the start-up testing. World needs to amend the Report text and /or Figure 5 to clarify when the HCVES was again fully operational. o Based upon data in the Report, the total down time for the HCVES for the conversion appears to be almost three months (31 July through or near the end of October 2006). This appears to be an inordinate amount of time for the HCVES to be non - operational to affect such a conversion. World needs to provide an explanation as to why the HCVES was non- operational for this length of time. 2006 Annual Remediation Summary Report • For calendar year 2006, approximately 86 tons of hydrocarbons and 0.5 tons of MTBE were removed by the HCVES from the subsurface below the former Sunland refinery site. Approximately 2,832 gallons of LPH were also removed via stinging of selected wells and as vapor condensate. • In response to a request from our office, TSG conducted a drinking water well survey west of the PG&E Kern Steam Plant property and also prepared a workplan for the installation of additional groundwater monitoring wells to monitor site constituents Former Sunland Oil Refinery - 5 - 25 August 2008 west/northwest of the former Sunland refinery site. On 17 July 2006 TSG submitted to our office the document entitled Well Installation Workplan and Water Well Summary dated 13 July 2006. We approved the well installation workplan in our letter dated 6 September 2006, The Report indicated that pre - installation activities were completed in late 2006 and the well installation was scheduled for early 2007. 2007 Semi - Annual Groundwater Monitoring and Status Reports First Half 2007 Semi - Annual Groundwater Monitoring and Status Report Groundwater samples were collected for the first time from the new groundwater monitoring wells; TSG -MW -114, A/B /C; TSG -MW -115, A/B /C; and TSG -MW -116 A/B /C; installed in January 2007. These wells were installed to provide additional vertical and lateral delineation of the western edge of the contamination plume in groundwater' TPHg concentrations from wells SE- MW -23D and SE- MW -20D were the highest reported during the April 2007 sampling event. Groundwater samples collected from wells SE -MW -23D and SE- MW -20D are reported to have TPHg concentrations of 2,600 pg /L and 1,800 pg /L, respectively. The concentration in SE -MW -23D is lower than the previous monitoring period and is significantly lower than most historical results. The concentration in SE- MW -20D is consistent with historical results. MTBE was not detected in well TSG- MW -23D, but was detected in well SE- MW -20D at a concentration of 98 pg /L. • The highest concentration of MTBE, 110 pg /L, was detected in newly installed well TSG- MW -115B. This well is approximately 2,900 feet west - northwest (downgradient) of what is anticipated to be the main MTBE source area, .the STF, at the former Sunland refinery. The second highest concentration of MTBE, 98 pg /L, was detected in well SE- MW-20D. • The highest concentration of benzene, 22 pg /L, was detected in newly installed well TSG- MW -115C. This well is approximately 2,900 feet west - northwest (downgradient) of what is anticipated to be the main source area at the former Sunland refinery. The second highest concentration of benzene, 5.8 pg /L, was detected in well TSG- MW -85C. In our 20 March 2006 review letter regarding the Second Half 2005 Semi - Annual Groundwater Monitoring and Status Report, based upon an analysis of historic MTBE data across the site, Regional Water Board staff suggested that the "lagging" benzene associated with a "slug" type MTBE release may have reached its peak concentration in well GMX- MW -62D in September 2005. The. results of the previous and current monitoring events indicated that benzene was not detected in well GMX -MW -62D, which appears to again confirm that the referenced benzene "slug" in groundwater has now migrated past well GMX -MW -62D. Well GMX -MW -62D is approximately 2,000 feet west - northwest (downgradient) of what is anticipated to be the main MTBE source area (STF) at the former Sunland refinery. Former Sunland Oil Refinery - 6 - 25 August 2008 Groundwater elevations at the site peaked in September 1999 and then declined until March 2005 at which time groundwater elevations began to rise. Since March 2005, the elevations continue rise. Since the last monitoring report, groundwater elevations rose approximately 6 to 8 feet in wells not in the immediate vicinity of active air sparging and vacuum extraction activities. This brings the total rise in the groundwater surface from March 2005 until April 2007 to 30+ feet in wells not in the immediate vicinity of active air sparging and vacuum extraction activities. Other wells show an apparent rise of approximately 45 feet but how much of this apparent rise may be influenced by the remediation activities of air sparging and soil vapor extraction is not known. The groundwater flow direction during this monitoring event was generally to the northwest at a gradient of approximately 0.009. This is in general agreement with recent monitoring results. o World failed to include analyses for oxygenates during the first semi - annual period 2007 groundwater sampling event which were required in the Regional Water Board letter titled Well Installation Work Plan Review dated 6 September 2006.. In addition to oxygenates, the samples should also be analyzed for 1,2 dichloroethane via USEPA Method 8260B and the results reported for all constituents for the next two monitoring events. Once the results are available and reviewed a determination can be made whether continuation of these analyses is warranted. Second Half 2007 Semi - Annual Groundwater Monitoring and Status Report The highest TPHg concentrations reported during the October 2007 sampling event are from wells SE- MW -23D and SE- MW -23S. Groundwater samples collected from wells SE -MW -23D and SE -MW -23S are reported to have TPHg concentrations of 30,000 and 3,100 pg /L, respectively. MTBE was not detected in either. well. The highest concentration of MTBE, 210 pg /L, was detected in well TSG- MW -83B. This well is approximately 2,000 feet west- northwest (downgradient) of what is anticipated to be the main MTBE source area at the former Sunland refinery. The second highest concentration of MTBE, 130 pg /L, was detected in well TSG- MW -115B. This well is approximately 2,900 feet west - northwest (downgradient) of what is anticipated to be the main MTBE source area at the former Sunland refinery. The highest concentration of benzene, 15 pg /L, was detected in newly installed well TSG- MW -115C. This well is approximately 2,900 feet west - northwest (downgradient) of what is anticipated to be the main source area at the former Sunland refinery. The second highest concentration of benzene, 8.7 pg /L, was detected in well SE -MW -23D. In our 20 March 2006 review letter regarding the Second Half 2005 Semi - Annual Groundwater Monitoring and Status Report, based upon an analysis of historic MTBE data across the site, Regional Water Board staff suggested that the "lagging" benzene associated with a "slug" type MTBE release may have reached its peak concentration in well GMX- MW -62D in September 2005. The results of the two previous and current monitoring events indicated that benzene was not detected in well GMX -MW -62D, which appears to further confirm that the referenced benzene "slug" in groundwater has Former Sunland Oil Refinery - 7 - 25 August 2008 now migrated past well GMX- MW -62D. Well GMX -MW -62D is approximately 2,000 feet west - northwest (downgradient) of what is anticipated to be the main MTBE source area, the STF, at the former Sunland refinery. In this same 20 March 2006 review letter, Regional Water Board staff further suggested that based upon these same calculations the core of the MTBE "slug" should be located about 700 to 1,000 feet downgradient of well GMX -MW -62D, at that time, or near the western PG&E property boundary. This estimate appears to have been correct based upon the detection of MTBE and benzene at concentrations that exceeds their respective Primary MCL for drinking water in new wells TSG -MW -115 B and C, constructed in January 2007, located near the PG&E boundary. Using the same seepage velocity for MTBE of 0.8 to 1.1 feet per day, previously calculated by Regional Water Board staff, and continuing the migration to the northwest since March 2006, the "slug" of MTBE may have migrated to date an additional 600 to 800 feet downgradient of new wells TSG -MW -115 B and C and beneath the adjacent property. This new estimated extent of the plume is approximately 3,600 feet downgradient of what is anticipated to be the main MTBE source area at the former Sunland refinery South Tank Farm. • Groundwater elevations at the site peaked in September 1999 and then declined until March 2005 at which time groundwater elevations began to rise. For the first time since March 2005, groundwater elevations declined at the site. Since the last monitoring report, groundwater elevations declined approximately 6 to 10 feet in wells not in the immediate vicinity of active air sparging and vacuum extraction activities. I reviewed groundwater elevations in wells located together and within and down gradient along the contamination plume. From these I calculated vertical hydraulic gradients. The vertical hydraulic gradient at wells GMX- MW -62(S) and TSG- MW -83B was calculated to be 0.094 and 0.157 for April and October 2007, respectively. The vertical hydraulic gradient at wells TSG- MW -115A and TSG- MW -115C was calculated to be 0.066 and 0.121 for April and October 2007, respectively. Comparison of groundwater elevations in the B and C wells of the TSG -MW -114 through 116 well clusters indicated negligible differences in wells TSG -MW -114 and 115. However, the difference in groundwater elevations for TSG- MW -116B and C were 5.12 feet lower and 6.48 feet lower in the C well in April and October 2007, respectively. The B well is screened from 160 -170 feet below ground surface (bgs) and the C well is screened from 198 -208 feet bgs. Review of the continuous core log for well 116 B/C indicates silt (ML - 65% silt, 20% fine sand, and 15% clay) was encountered from 175 to 182 feet bgs, between the screened intervals of these wells. Additional zones logged as silty sand (with up to 25% silt) were also encountered in the interval between the screens in wells 116B and C. Collectively, this suggests some hydraulic separation may exist between the zones monitored by each well, The groundwater flow direction during this monitoring event was generally to the northwest at a gradient of approximately 0.006. This is in general agreement with recent monitoring results. Former Sunland Oil Refinery - 8 - 25 August 2008 o World did not present the results of all groundwater analyses in tables within the Report. During this sampling event groundwater samples were collected from select wells and analyzed for arsenic, total chromium, and hexavalent chromium (chromium VI). However, the results of these analyses were not presented in data tables within the Report. World needs to ensure that future reports present current and historic results of all laboratory analyses of groundwater samples for arsenic, total chromium, and hexavalent chromium in a table(s) within each report, as are the results for other analyses. o World failed to incorporate analyses for oxygenates during this sampling event which were required in the Regional Water Board letter titled Well Installation Work Plan Review dated 6 September 2006. In addition to oxygenates, the samples should also be analyzed for 1,2 dichloroethane via USEPA Method 82608 and the results reported for all constituents for the next two monitoring events. Once the results are available and reviewed a determination can be made whether continuation of these analyses is warranted. 2007 Semi - Annual Remediation Progress Reports First Half 2007 Remediation Progress Report • The HCVES operated, in catalytic mode, approximately 2,815 hours during the reporting period (78 percent of the time). • An estimated 16.8 tons (33,600 pounds) of hydrocarbons were extracted and destroyed by the catalytic oxidizer during this reporting period. This brings the cumulative total of hydrocarbons treated to 3,835.4 tons since vapor extraction was initiated at the site on 22 March 1996. • An estimated 101 pounds of MTBE was extracted and destroyed by the catalytic oxidizer during the reporting period. This brings the cumulative total of MTBE treated to 19.6 tons since October 1996; the earliest date data was available for MTBE. • Approximately 1,682 gallons of LPH was collected by the HCVES and an additional 133 gallons of LPH was manually bailed or removed from affected wells by a vacuum truck. In total, 1,815 gallons of LPH were removed from the site during the reporting period and the total amount of LPH removed since December 1996 is approximately 13,749 gallons. • Table 3 in the Report fails to include 7" in the "Note" column for monitoring performed on 22 January 2007 indicating that HCVES influent samples were collected for laboratory analysis. Second Half 2007 Remediation Progress Report o The Report states that the HCVES operated, in the flare mode, approximately 2,523 hours during the reporting period (49 percent of the time). World needs to provide an explanation as to why the HCVES operated so little during this reporting period. Former Sunland Oil Refinery - 9 - 25 August 2008 • An estimated 20 tons (40,000 pounds) of hydrocarbons were extracted and destroyed by the flare during the reporting period. This brings the cumulative total of hydrocarbons treated to 3,855.4 tons since vapor extraction was initiated at the site on 22 March 1996. • An estimated 328 pounds of MTBE was extracted and destroyed by the flare during the reporting period. This brings the cumulative total of MTBE treated to 19.8 tons since October 1996; the earliest date data was available for MTBE. o Approximately 1,181 gallons of LPH was collected by the HCVES and an additional 157 gallons of LPH manually bailed or vacuumed from affected wells by a vacuum truck. In total, 1,338 gallons of LPH were removed from the site during the reporting period. The Report states that as of this reporting period the total amount of LPH removed since December 1996 is approximately 15,009 gallons. However, my calculations for LPH removal since the previous monitoring report are as follows: First Half 2007 LPH Project Total Second Half 2007 Period Total New LPH Project Total 13,749 gallons 1,338 gallons 15,087 gallons (not 15,009 as reported) World needs to recheck the LPH calculations and amend the text and Table 1 of the Report as necessary. o Data within the Report indicates that the entire HCVES was off from 12 April 2007 through 6 June 2007, almost 2 months. World needs to provide an explanation of why the HCVES was off during this period. o In Table 2g, the AS System Process Summary lists the "Air Sparge Flow Rate Per Well" as 39,217 scfm, which appears incorrect. World needs to check and amend as necessary. o In Table 3 of the Report, the column "Notes" shows no entries, which is in contrast to previous reports. World needs to explain why no "Notes" are included in Table 3 of the Report. If this is in error, World needs to incorporate the necessary information and submit an amended Table 3 to this office. o Figure 5 in the Report depicts periods when the HCVES, the South Tank Farm (STF) air sparging (AS), and WTF AS systems are "On" or "Off', Data in Figure 5 for the system status does not agree with system operational status as recorded in the High Capacity Soil Vapor Extraction /Air Sparge Monitoring Logs contained in Attachment D "O & M Field Logs" or with specific system status shown in Table 3. World needs to check, amend portions of the Report as necessary, and resubmit the amended portions of the Report to this office. o Figure 5 in the Report indicates that the air sparging system in the West Tank Farm (WTF) has operated very little since mid - January 2007. World needs to provide an explanation as to why it was operated so little. Former Sunland Oil Refinery - 10- 25 August 2008 • In Attachment D, the first set of field vapor extraction monitoring logs do not identify the technician's name, initials, and date the readings were taken. o There appears to be a possible contradiction in Attachment D, O & M Field Logs for 15 August 2007 and 23 August 2007. The former field log fails to indicate the HCVES departure status for Blower 2 and the arrival and departure status for the WTF AS system. In addition, this field log indicates in the notes /activities section that the system shut down due to a High /High condition in the AST [aboveground storage tank]. However, the HCVES system arrival and departure status indicates "On" for both. The next system check field log for 23 August 2007 indicates that the HCVES was "Off' upon arrival and in the notes /activities section it indicates that the AST was emptied. It appears that the system shut down note may belong on the 23 August 2007 field log. World needs to review and clarify. o Similar to the issue discussed in the previous comment, the 30 August 2007 HCVES / AS Monitoring Log does not indicate HVCES Blower 2 departure status, AS STF departure status, nor the AS WTF arrival and departure status. World needs to ensure that the HCVES / AS Monitoring Logs are properly completed in the field by personnel monitoring the system. o Field Memoranda, provided in Attachment D of previous reports, are not included in the current Report. World needs to include all Field Memoranda in Attachment D of all future Remediation Progress Reports. o Information in the Report indicates that the catalytic oxidizer was taken off line and the flare system brought back on line. World needs to provide an explanation as to why. o In the Summary of Individual Well Concentrations, Vacuums, and Depths to Product/Water tables, contained in Attachment B of the Report, some of the Product Thickness values are not reported even though data on the Depth to Water and Depth to Product are present in the table. Examples in the 6 June 2007 measurements include wells AS -81 b and SE- MW -9(R); well MW -5 in the 15 August 2007 measurements. Similarly, there are several other wells in the Summary tables for other dates also lacking this information. World needs to update the Attachment B tables as necessary and resubmit them to this office. o World needs to provide an explanation as to why concentration or vacuum data for the vapor extraction wells (TSG —VE -90 through TSG- VE -96), located on PG&E property, are not included in the tables contained in Attachment B of the Report. o In wells with liquid petroleum hydrocarbons but comparatively low measured hydrocarbon vapor concentrations, World needs to sample the liquid product and analyze the samples for carbon chain C -6 through C-44 to identify the hydrocarbon product and determine if this product is amenable to remediation by the HCVES. The product may be composed of less volatile hydrocarbons such as kerosene or diesel and not respond well to the HCVES. Former Sunland Oil Refinery - 11 - 25 August 2008 2007 Annual Remediation Summary Report The Report indicates that for the calendar year 2007, the high capacity vapor extraction system removed and destroyed approximately 30 tons of petroleum hydrocarbons and 0.3 tons of MTBE from the subsurface below the former Sunland refinery site. Approximately 1,680 gallons of LPH were also removed via stinging of selected wells and as vapor condensate. This brings the cumulative total to 3,856 tons and 20 tons of hydrocarbons and MTBE, respectively, removed to date. o The reported 30 tons of hydrocarbons removed in 2007 is significantly less, only 35 %, of the estimated 86 tons reported removed in 2006. The amounts of both LPH and MTBE recovered /destroyed in 2007 are also significantly less with both being about 60 %; 2,832 gallons and 0.5 tons; respectively; of that reported for 2006. World needs to provide a discussion regarding the significant decline in the amounts of these constituents removed in 2007 as compared to 2006, o Under the heading Assessment Activities, the Report states that no additional assessment activities were performed in relation to the former Sunland refinery site during calendar year 2007. 1 believe that additional information should be included in this section of the Report. In the Annual Remediation Summary Report (2006) (2006. Summary Report) under the heading Assessment Activities, the report summarizes our request for the installation of additional groundwater monitoring wells for the purpose of monitoring site constituents west and northwest of the former Sunland refinery site. Our request was made to further assess the lateral and vertical extent of groundwater impacted by petroleum hydrocarbons migrating from the Sunland site. The 2006 Summary Report also states that SGI submitted a workplan for well installations, that our office approved the workplan, and that SGI completed pre - drilling activities in late 2006. The 2006 Summary Report also stated, "Well installation was completed in early 2007, and will be documented within the Annual Remediation Summary Report for calendar year 2007'. However, no such documentation of the well installations was found in the Annual Remediation Summary Report for 2007. World should revise the Assessment Activities section of the Report to include a discussion of the installation of the three well clusters TSG- MW- 1 14A/B/C, - 115A/B /C and - 116A/B /C; the sampling of the wells during each of the two regularly scheduled semiannual sampling events in 2007; and the analytical results of those sampling events. Although the analytical results of sampling these new wells are contained within Table 1 — Historical Groundwater Analysis and Gauging Results, and in the two Groundwater Hydrocarbon Concentration Maps within the Report, the results and conclusions should be discussed in the Report text due to the significance of the detection of MTBE and benzene in excess of drinking water standards in wells TSG- MW -115 B and C, respectively, at depths from approximately 160 to 210 feet and 2,900 feet west - northwest (downgradient) of the anticipated source area of the former Sunland refinery. o On page 3, paragraph 1, the Report states in pertinent part, "Vapor samples were collected from the inlet header(s) for laboratory analysis once a month ". In my review of the two semi- annual remediation progress reports, there are no analytical results Former Sunland Oil Refinery - 12 - 25 August 2008 reported for influent vapor samples collected during the months of April and June 2007, The Process /Influent Concentrations (STF, WTF, PG &E combined) reported in Table A contained within Appendix A of the Report indicates, "System off -line" during April and June suggesting this is the reason samples were not collected these months. However, data in the respective semi - annual remediation progress reports indicated that the HCVES was operational from 1 April through 12 April and from 6 June through 30 June. Therefore, sufficient operational time existed each month during which samples could reasonably have been collected. World should modify the Report to be accurate and state when process /influent vapor samples were collected for analysis, o in addition, process /influent concentrations are reported in Table A of the Report and laboratory reports are found in Attachment A of the Second Half Semi - Annual Remediation Progress Report (2007) for samples collected on 21 May 2007 even though data from both 2007 semi - annual remediation progress reports indicates that the HCVES and air sparging systems were all off continuously from 13 April 2007 through 6 June 2007. World should explain how process /influent vapor samples could not be collected in April and June 2007 due to "system off - line" and yet samples were apparently collected 21 May 2007 even though the entire remediation system was off - line from 13 April 2007 through 6 June 2007. Summary Comments • Selected results for groundwater samples collected in 2006 and 2007 are presented in the enclosed Table 1. Monitoring well locations are depicted in the enclosed Figure 3 from the Semi - Annual Groundwater Monitoring and Status Report — Second Half — 2007, dated 21 December 2007. Based upon the above, the lateral and vertical extent of the petroleum hydrocarbon contamination in groundwater has not yet been defined. Analytical results of groundwater sampling now indicates that the plume of degradation, which exceeds the Primary MCLs for some constituents, extents to depths of at least 200 feet in the areas of wells SE- MW -20D, TSG- MW -83B, and TSG- MW -115C and possibly deeper. In addition, the groundwater. degradation extends at least 2,900 feet west northwest (downgradient) of what is anticipated to be the main MTBE source area at the former Sunland refinery. Based upon previous Regional Water Board staff estimates of the rate of contaminant plume migration, the plume may now have migrated to the northwest approximately 600 to 800 feet beyond wells TSG -MW -115 B and C. Since wells TSG- MW -115B and C are located approximately 115 feet east of the western PG &E property boundary, it appears likely that the plume of groundwater degradation extends to the northwest beyond the western PG &E property boundary, and beneath the adjacent property to the west. o With the new hydrogeologic and groundwater data now available from the installation and sampling of new groundwater monitoring wells, World needs to prepare an updated interim evaluation monitoring report summarizing the geologic data and laboratory analytical data for analyses of soil and groundwater. This should include, but not be limited to, updated geologic cross - sections depicting geology, well construction details, analytical data on soil samples, and groundwater analytical results including isopleth Former Sunland Oil Refinery -13- 25 August 2008 maps depicting concentration contours of all constituents of concern in each hydrostratigraphic unit identified. The report shall provide sufficient detail to be the basis for and should include proposals for additional investigative work to delineate the lateral and vertical extent of groundwater impacted by petroleum hydrocarbons. o Based upon the above, World needs to prepare a draft fact sheet on the investigative work completed to date and the findings. The draft fact sheet shall be submitted to this office for review and comment. World shall also provide a list of parcels, including Assessor Parcel Number (APNs), located within 500 feet of the site; the associated names and addresses of property owners and /or residents for each parcel, and any other interested parties or groups. For purposes of this requirement, "site" refers to all parcels with known contamination or which overlie known contamination that originated from the former Sunland refinery. Once the draft fact sheet is approved by this office, World will need to distribute the fact sheet to the property owners, residents, and other interested parties on the list described above, o The remediation system at the site has been in operation since March 1996, a period of approximately 12 years. Reports indicate that as of the end of 2007, the remediation efforts have removed a total of 3,856 tons of petroleum hydrocarbons and 20 tons of MTBE from the subsurface below the former Sunland refinery site. World should prepare a more extensive Remediation Progress Report that includes, but is not necessarily limited to, reporting changes in hydrocarbon product types and concentrations in soil and groundwater relative to the initiation of remediation efforts and over the last two years; the types and estimated amounts of hydrocarbon product(s) remaining in the subsurface including floating product on the water table; changes in the hydrocarbon vapor concentrations from individual wells and HCVES influent concentrations over time; graphical data presentations, such as isopleth concentration contours on plan view maps and cross sections, depicting the changes over time and current conditions; an evaluation of the impacts, both positive and /or negative, of fluctuations in the groundwater table elevation on remediation efforts; providing sufficient information, analysis and conclusions to support recommendations for changes, if any, or why no changes to the remediation efforts are warranted; and providing an updated estimate as to the time required under currently known conditions to complete remediation of the site.

February 19,2009 Mr. Russell W. Walls Senior Engineer California Regional Water Quality Control Board Central Valley Region 1685 E. Street Fresno, California 93706 Subject: WELL INSTALLATION WORKPLAN Former Sunland Oil Refinery 2152 Coffee Road Bakersfield, California Dear Mr. Walls: e n al SOURCE GROUP IHC. The Source Group, Inc. (SGI), on behalf of World Oil Corp. (World), has prepared this workplan for the installation of four off -site groundwater monitoring wells (to be designated TSG -MW- 117A/B/C/D) consisting of four separately drilled monitoring wells within a well cluster. Each of the proposed wells within the well cluster will be screened at a discrete depth interval within the aquifer with well casings installed within an approximate 5 -foot radius of each other. All of the proposed wells will be located northwest of the above - referenced site on private property west of the former Pacific Gas & Electric (PG &E) facility (Figure 1). The wells are proposed following discussions with the Central Valley Regional Water Quality Control Board (CVRWQCB) regarding hydrocarbon constituents, including MtBE, in groundwater within downgradient wells currently located on the PG &E property. The purpose of proposed well cluster TSG- MW- 1 17A/B /C /D is to allow lateral and vertical delineation of dissolved -phase MtBE in groundwater downgradient of the site. Well installation will be contingent upon obtaining a signed access agreement from the owners of the property where the proposed well cluster will be installed. It is World's understanding that the property in question is currently owned by John Balfanz Development, LLC. Health and Safety Plan All field activities will be completed with safety as a foremost concern. A site - specific health and safety plan (HASP) will be prepared for the drilling and well installation activities at the proposed location. All SGI personnel, subcontractors, and regulatory personnel performing field work on the project will be required to familiarize themselves with and sign the HASP in order to minimize safety hazards. In addition to containing Material Safety Data Sheets for the chemicals expected at the site, the HASP will identify the specific chemical compounds that are typical for refinery operations and will present their chemical properties and a task - specific health and safety risk analysis. 299 West Hillcrest Drive Telephone: (805) 373 -9063 Suite 220' Facsimile: (805) 373 -9073 Thousand Oaks, California 91360 e -mail: mlabrenz @thesourcegroup.net Mr. Russell W. Walls California Regional Water Quality Control Board February 19, 2009 Former Sunland Oil Refinery Page 2 Bakersfield, California Utility Clearance Prior to drilling, the boring locations will be clearly delineated using white marking paint. Underground Services Alert (USA) will be contacted at least 48 -hours prior to the planned subsurface exploration and requested to identify any potential underground utilities that may be near the pre- marked locations. Prior to drilling at each location, the upper 5 feet of each borehole will be excavated and widened to the width of the drill casing either by hand using a hand auger with a post -hole digger, or mechanically using an air knife rig. Well Permitting Prior to initiating fieldwork, well permits will be obtained from Kern County Environmental Health Services Department (KCEHSD) for the installation of all the aforementioned wells. Sample Collection and Analytical Methods Drilling will be performed using a sonic drilling rig and /or hollow stem auger drill rig. Soil samples for potential chemical analyses and logging purposes will be collected at a minimum of five -foot intervals to the total expected depth of 250 feet below ground surface (bgs) from the deepest borehole. Soil samples will be retained in six -inch long brass sample sleeves, sealed with Teflon® sheets and end caps, and placed in a cooler containing ice (preserved) for transportation to the laboratory. Soils will be additionally monitored for volatile organic vapors by the headspace method using a hand -held photoionization detector (PID). All samples will be submitted for analysis to State - certified American Analytics of Chatsworth, California using standard chain -of- custody protocol. Prior to drilling each boring, the drill casings will be pressure- washed to prevent cross contamination between sampling locations. All sampling equipment will be cleaned in an aqueous solution of non - phosphate cleanser, rinsed with tap water, and rinsed a second time with deionized water to prevent cross contamination between borings and sample intervals. Soil cuttings generated during drilling activities will be retained in soil bins and transported to the Former Sunland Refinery. Soil cuttings will be analyzed for constituents of concern and with either be deposited at the former Refinery site under San Joaquin Valley Air Pollution Control District oversight or disposed off site at an appropriate disposal facility. Decontamination water will be placed in labeled, DOT - approved 55- gallon steel drums and stored at the former Sunland Refinery pending disposal /recycling or treatment. All waste materials will be handled in accordance with Federal, State, and local regulations. Selected soil samples from each borehole will be analyzed for total petroleum hydrocarbons as gasoline (TPHg); benzene, toluene, ethylbenzene, total xylenes (BTEX); and methyl tertiary- butyl ether (MTBE) by EPA Method 826013. At least four soil samples will be submitted for laboratory analysis (including one from the soil /water interface). The Source Group, Inc. Mr. Russell W. Walls February 19, 2009 Page 3 Well Installation and Development California Regional Water Quality Control Board Former Sunland Oil Refinery Bakersfield, California A well cluster (i.e., a group of wells each installed into separate boreholes drilled to different depths approximately five feet apart) consisting of four single- nested wells will be installed northwest of the Former Sunland Refinery on private property west of the former PG &E facility, as shown on Figure 2. The proposed well cluster location will be near the center of the referenced property, just to the northeast of an existing irrigation well that is no longer in use. All four wells will be constructed using four -inch diameter Schedule 80 PVC casing. Each well (TSG- MW -117A, -B, -C, and -D) will be constructed within a single borehole. The proposed screened intervals of the wells will be as follows: • TSG- MW -117A: 78 to 130 feet bgs (to intercept the water table); • TSG- MW -117B: 160 to 175 feet bgs; • TSG- MW -117C: 200 to 210 feet bgs; and • TSG- MW -117D: 240 to 250 feet bgs. Each of the individual wells will be completed using 0.020 -inch slotted screens. The annuli surrounding the screened intervals will be filled with No. 2/12 sand. During installation of the filter sand in each well, the well will be surged and bailed to properly settle the filter pack and to remove fine - grained sediment from the well. Each well will be sealed with hydrated bentonite pellets followed by bentonite grout. The wells will be completed at the surface using lockable steel well monuments that will each be affixed with a security padlock. At least 72 hours after the completion of well installation, all four wells will be developed using a well development rig in order to further develop the filter pack to prevent infiltration of fine - grained formation material into the well, and to remove any fines that accumulated in the wells during drilling. The wells will be surged and bailed and /or pumped. Water quality parameters, including turbidity readings will be recorded periodically during well development to evaluate the success of the development in removing fines from the wells. Newly installed well casings will be professionally surveyed and tied into the existing surveyed monitoring well network. Reporting Following the completion of field activities, a Well Installation Report will be prepared, which will include pertinent field data, tabulated soil analytical results, soil boring logs and well completion information, and a site map depicting the new well cluster location. Laboratory reports will be provided in the report as an appendix. The report will be reviewed in its entirety and stamped by a California Professional Geologist. The new well cluster will be added to the site's semi - annual GWM &S program and will be initially sampled during the first semi - annual GWM &S event following well installation. Schedule SGI anticipates that the well installation fieldwork described herein will be completed in March or April 2009 following written approval to proceed from the CVRWQCB. The work will be contingent The Source Group, Inc. Mr. Russell W. Walls February 19, 2009 Page 4 California Regional Water Quality Control Board Former Sunland Oil Refinery Bakersfield, California upon World's procurement of a signed access agreement from the owners of the property where the proposed well cluster will be installed.

VAPOR EXTRACTION WELL INSTALLATION WORKPLAN, Former Sunland Oil Refinery, 2152 Coffee Road, Bakersfield, California (Site) dated 18 September 2009 (Workplan). The Workplan was prepared and submitted by The Source Group, Inc. (SGI) of Thousand Oaks, California on behalf of World Oil Corporation (World). Based upon our review, the Workplan is approved. Workplan Summary World proposes to install four soil vapor extraction (SVE) wells (TSG -SVE -118 (P) through TSG- SVE -121 (P)) within the former South Tank Farm area at the locations depicted on the enclosed Figure 2 from the Workplan. The SVE wells are to supplement the existing SVE wells and to extract from a deeper zone designated the Lower 2 Vadose Zone (1-2VZ), now exposed due to the continuing decline in groundwater elevations in the area. The SVE wells are proposed to be screened from depths of approximately 120 to 170 feet below ground surface (bgs). With the current water table at approximately 150 feet bgs, this will extend the life of the SVE wells should groundwater elevations continue to decline and will also allow them to currently be used as groundwater monitoring wells.. Additional details of the proposed SVE well installations are provided in the Workplan. By 1 February 2010, World shall submit an SVE well installation report containing, at a minimum, all the elements stated in the Workplan.

(World), The Source Group, Inc. (SGI) submits this Second Half 2008 Remediation Progress Report for the former Sunland Oil Refinery located in Bakersfield, California. Included with this report are the following: 1. Site location map (Figure 1); 2. Site map showing remediation well locations (Figure 2); 3. Cumulative vapor -phase hydrocarbon removal graph and MtBE removal graphs (Figures 3 and 4 respectively); 4. Graph showing high capacity vapor extraction system (HCVES) and air sparge (AS) system status and hydrocarbon mass removed during the Second Half 2008 reporting period (Figure 5); 5. Second Half 2008 HCVES, AS system, and liquid -phase hydrocarbon (LPH) recovery .summary (Table 1); 6. Monthly HCVES and AS system operational data summaries for the reporting period (Tables 2a through 2g and Table 3); 7. Summary of Individual Well Data (Table 4) 8. Analytical laboratory reports and chain -of- custody records for vapor samples collected during the reporting period (Attachment A); 9. Individual well vapor concentration and vacuum data (Attachment B); 10. Copies of Waste Manifest forms (Attachment C); and 11. Daily field logs (Attachment D). The HCVES system operated in flare mode approximately 1,724 hours during the Reporting Period. The Baker Furnace operated in thermal mode for approximately 2,374 hours during the operating period. The sum total operating time between the two vapor abatement devices was 4,045 hours during the reporting period. An estimated 65.0 tons of hydrocarbons were extracted and destroyed by the John Zink Flare and Baker Furnace thermal oxidizer during this reporting period, bringing the cumulative total of hydrocarbons treated to 3,946.7 tons since the inception of vapor .extraction at the site on March 22, 1996. An estimated 1,319 pounds of MtBE were extracted and destroyed by the John Zink Flare and Baker Furnace thermal oxidizer during the reporting period, bringing the cumulative total of MtBE treated to 20.7 tons since October 1996, the earliest date MtBE data was available. 299 West Hillcrest Drive Telephone: (805) 373 -9063 Suite 220 Facsimile: (805) 373 -9073 Thousand Oaks, California 91360 e -mail: mlabrenz @thesourcegroup.net Mr. Daniel Carlson, CVRWQCB Second Half 2008 Remediation Progress Report December 31, 2008 . Page 2 Approximately 4,000 gallons of liquid, including liquid phase hydrocarbons (LPH) . and condensate generated during soil vapor extraction were removed from the site during the reporting period by Asbury Environmental Services and transported to Demenno Kerdoon in Compton, California for disposal /recycling. Approximately 200 gallons of LPH was collected by the HCVES (visually estimated at 5 percent of the liquid collected in the condensate knockout tanks). The total amount of LPH removed since December 1996 is approximately 15,829 gallons.

SEMI- ANNUAL GROUNDWATER MONITORING AND STATUS REPORT SECOND HALF - 2008 Client: World Oil Corp. Location: Former Sunland Refinery, 2152 Coffee Road, Bakersfield California Client Contact/Phone No.: Mr. John Hundley/ (562) 928 -0100 Consulting Co. /Contact Person /Phone No.: The Source Group, Inc. / Mark Labrenz / (805) 373 -9063 The Source Group Project No.: 02 -WOC -088 Agency /Regulatory ID No,: RWQCB - Central Valley Region / Mr. Daniel Carlson / File #CAO 95 -702 WORK PERFORMED (June 2008 through December 2008): 1. Wayne Perry, Inc. (WPI) measured groundwater (and liquid petroleum hydrocarbon [LPH] levels, when present) in the groundwater monitoring wells on September 15, 2008. 2. WPI purged and sampled on- and off -site groundwater monitoring wells on September 16 through 19, 2008. Purge water was temporarily stored on site and subsequently transported to DeMenno / Kerdoon for recycling. Dissolved oxygen (DO) and oxidation - reduction potential (ORP) were additionally measured during purging of select wells as part of the ongoing natural attenuation study. 3. SGI operated the high capacity vapor extraction system (HCVES) utilizing the John Zinc Flare from June 1 (first day of second half 2008 reporting period) through July 21, 2008. The HCVES was shut down to conduct system retrofit activities from July 21 through August 14, 2008. The HCVES was brought back into operation on August 14, 2008 utilizing the Baker Furnace thermal oxidizer as the primary abatement device through the end of the reporting period (December 31, 2008). 4. SGI continued air sparging at the former West Tank Farm (WTF) and former South Tank Farm (STF) areas of the Sunland site, as well as the PG &E property north of the railroad tracks. 5. Retrofit activities were conducted on the HCVES from July 21 to August 14, 2008 in order to upgrade system operational performance. System retrofit included the replacement of the two existing knock out tanks with upgraded tanks, repositioning of the automated dilution valves, incorporation of LEL fail -safe sensors at each blower inlet, and replacement of the Eclipse Veri -Flame flame monitoring controller (which at the time had been involved in a recall due to units allowing continuous gas flow to the burn chamber in the absence of a flame). The Baker Furnace oxidizer was brought back online (thermal mode) as the primary abatement device on August 14, 2008, following the retrofit activities described above. As requested by the Central Valley Regional Water Quality Control Board (CVRWQCB) in a letter to World Oil Corp. dated November 28, 2006, additional fuel oxygenate analysis was performed on groundwater samples collected from well clusters SGI -MW -114 A/B /C, SGI -MW -115 A/B /C, and SGI -MW -116 A/B /C. Tertiary butyl alcohol (tBA), di- isopropyl ether (DIPE), ethyl tertiary butyl ether (EtBE), tertiary amyl methyl ether (TAME), ethanol, methanol, EDB, and EDC were analyzed during second half 2008 sampling episode (Table 2). Historical fuel oxygenate analysis is included within Table 5. As requested by the CVRWQCB in a letter to World dated August 25, 2008, World submitted two supplemental data reports during second half 2008. The report entitled Addendum Report in Response to RWQCB Letter Dated August 25, 2008, Former Sunland Oil Refinery, Bakersfield, California was submitted to the CVRWQCB on November 10, 2008. The report entitled Interim Evaluation and Remediation Progress Report Former Sunland Refinery, 2152 Coffee Road, Bakersfield, California was submitted to the CVRWQCB on November 28, 2008. 299 West Hillcrest Drive Telephone: (805) 373 -9063 Suite 220 Facsimile: (805)373 -9073 Thousand Oaks, California 91360 e- mail =. mlabrenz @thesourcegroup.net Date: December 31, 2008 8. As requested by the CVRWQCB in a letter to World Oil Corp. dated August 25, 2008, arsenic, total chromium, and hexavalent chromium historical groundwater analytical results from groundwater monitoring wells installed by World at the PG &E Kern Steam Plant are tabulated and included within this semi - annual groundwater monitoring report within Table 7. Laboratory reports for arsenic and chromium analysis are included as Appendix C. WORK PROPOSED FOR NEXT PERIOD (January 2009 through May 2009): 1. Complete groundwater gauging, purging, and sampling in March 2009. 2. Continue operation and maintenance of the high capacity vapor extraction system (HCVES) and air sparge (AS) system. Continue LPH removal from affected on -site wells using a vacuum truck and /or stingers. A workplan will be submitted to the CVRWQCB outlining the installation of four additional groundwater monitoring wells (TSG- MW- 1 17A/B /C /D) to be installed approximately 1,000 feet to the west - northwest of existing monitoring well TSG -MW -115. The wells will be installed within an approximate 5 to 10 foot radius of each other and will be screened at discrete depth intervals within the shallow hydrostratigraphic zones defined for the site. The proposed wells will be installed with the objective of defining the lateral as well as vertical extent of hydrocarbon constituents [total petroleum hydrocarbons as gasoline (TPHg), benzene, and methyl tertiary butyl ether (MtBE)] in groundwater downgradient of the former Sunland Refinery site. In order to install the above referenced wells, World will attempt to enter into an access agreement with the owner of the property directly west of the former PG &E Kern Steam Plant.

Appendix A Groundwater Monitoring Procedures The Some Gronp, Inc. Date: December 31, 2008 GROUNDWATER MONITORING PROCEDURES FORMER SUNLAND OIL REFINERY 2152 Coffee Road, Bakersfield, CA Groundwater Gauging. Each well was located and inspected prior to gauging by Wayne Perry, Inc. (WPI). Using a SolinstTm oil /water interface probe, each well was then gauged for depth to groundwater, depth to liquid -phase hydrocarbons (LPH) if present, and total well depth (if no LPH was present). Gauging devices were decontaminated between each well using a triple -rinse method of tap water with non - phosphate detergent, tap water, and then deionized water. The sampling sequence was based on the analytical results obtained during the previous sampling event. Wells showing petroleum hydrocarbon sheen during gauging or purging were sampled only if sheen was not observed following purging and recovery. Wells containing floating product were not sampled; however, the thickness of floating product in LPH affected wells was measured and recorded. Groundwater Purging and Sampling. Groundwater monitoring wells were purged and sampled by WPI. Wells were purged of water using either a PVC bailer, electric pump, or micro - purged using a RediFlow pump. Fast recharging wells were purged of three well casing volumes of water. Slow recharge wells were purged until dry and allowed to recover for two hours or until the well recovered 80 percent of the initial water column height before sampling. During purging, water parameters including pH, temperature, conductivity, and turbidity were monitored to ensure stabilization within 10% of each parameter and ensure that groundwater representative of the aquifer was entering the well. Additionally some groundwater monitoring wells were also measured for dissolved oxygen (DO) and oxygen reduction potential (ORP) using a field monitoring device. DO and ORP were measured through a flow cell during both the beginning of purging (identified as pre - purge) as well as at the end of purging (identified as post - purge). The bailer used for well purging was decontaminated between each well using a triple -rinse method of tap water and non - phosphate detergent, tap water, and then deionized water. The pump was decontaminated by cycling the washwater through the pump followed with a deionized water rinse. Groundwater samples were collected using a polyethylene disposable bailer attached to new nylon cord. Samples were transferred to containers provided by the laboratory appropriate to the analysis to be performed. The containers were capped with Teflon TM septa, labeled, and placed on ice for transport to State - certified American Analytics, of Chatsworth, California. New sampling equipment (nylon cord, bailer, etc.) was used on each well to deter potential cross - contamination. Quality Assurance /Quality Control (QA/QC) Samples. Quality control samples submitted to the laboratory included one laboratory- prepared trip (or travel) blank. One trip blank was kept in the sample cooler and submitted to the laboratory with the groundwater samples. WPI initiated a Chain - of- Custody record in the field immediately following sample collection to accompany the samples to the laboratory. Liquid -Phase Hydrocarbon (LPH) Removal. LPH is removed from wells using one of the following methods: • Flexible PVC stingers that extract the LPH via airlift created by the vacuum extraction blower; • Bailing of affected wells; or • Vacuum truck service. Waste Disposition. Purge water generated during this monitoring event was removed by vacuum truck and transported under manifest to DeMenno /Kerdoon in Compton. Second half 2008 waste recycling /disposal documentation is provided within Appendix E of this report. The Source Group, Inc.
