In addition, this report documents the remediation status for the Site. This report has been prepared by E2C for Mr. Nassri Jaber to document site conditions as required by the State of California Regional Water Quality Control Board — Central Valley Region, the Lead Regulatory Agency in ongoing directive letters, most recently dated April 13, 2007. Discussion of Groundwater Monitoring Data The groundwater flow direction and gradient in the Second Quarter 2008 were consistent with interpreted historic flow directions and gradients. In the Second Quarter 2008 dissolved -phase COCs were reported as non - detect at well MW -1, except for TPHg being reported at a concentration of 1,630 gg /L at that well. At the upgradient (somewhat cross - gradient) monitoring well (MW -4), fuel constituents of concern (COCs) of benzene, toluene, ethylbenzene and xylenes (BTEX) and Total Petroleum Hydrocarbons as gasoline (TPHg) have been reported as non - detect for twelve (12) consecutive quarters. Similarly, at MW -2, located downgradient and cross - gradient to the southwest, COCs have been reported as non - detect for fifteen (15) consecutive quarters. At MW -1, the Source Area monitoring well, COC concentrations rebounded slightly in the First and Second Quarters 2008. In July 2007, COCs rebounded slightly at MW -3, however, have shown a declining trend since that time. At the furthest downgradient well (MW -5), sporadic low concentrations of dissolved -phase COCs were reported prior to August 2005. Since that time, all COCs have been reported as non - detect at that well. This data indicates that remedial operations at the Site had been effective in reduction of `source' mass in the Source Area vadose zone and in reduction of dissolved -phase components in groundwater throughout the Site; however, it appears that rebound in dissolved phase COCs have recently occurred in the area of well MW -1 with significant residual concentrations (that continue to show a decreasing trend) still present in the area of MW -3. Additionally, the moderate concentrations of COCs at MW -3 indicate that a groundwater `source' mass occurs in the area between MW -1 and MW -3 and may extend somewhat downgradient from MW -3; however, migration offsite has not progressed any great distance, as COCs are non - detect at MW -5. Note: 1,2- Dichloroethane (1,2 -DCA) and 1,2- Dibromomethane (a.k.a. ethylene dibromide) (EDB), were reported as non - detect in groundwater at the Site since December 2004. The analysis for 1,2 -DCA and EDB were discontinued per the RWQCB letter dated December 21, 2006. Additionally, the five fuel oxygenates of methyl tertiary-butyl ether (MtBE), di- isopropyl ether (DI PE), ethyl tertiary-butyl ether (ETBE), tertiary-amyl methyl ether (TBA) and tertiary- butyl alcohol (a.k.a. tert- butanol) (TBA) have been reported as non - detect at all wells since August 2005. E2C Remediation ' Proiect Number 1803BK26 October 6.2008 Summary of Remediation Status Remedial system influent concentration averages indicated that the thermal /catalytic oxidizer ' unit had reached the limit of its effectiveness for continual operations mode, and that the time and costs necessary to modify the remedial system to an electric /catalytic oxidizer were ' prohibitive. Therefore, the site remediation system was shut down in July 2006. Based on recent rebound of low to moderate COCs in groundwater beneath the Site, restart of the thermal oxidizer unit is, warranted. As such, E2C recommended restart of the system. The RWQCB in verbal communication with E2C concurred with this conclusion and E2C restarted ' the remedial system using thermal catalytic treatment on August' 22, 2008. Conclusions ' Based on the site assessment work, groundwater monitoring data and remedial operational data obtained at the Site to date, E2C concludes the following: • The average groundwater elevations beneath the Site decreased an average of 2.54 ' feet in the Second Quarter 2008. The groundwater flow directions were southeasterly, which were consistent with historic groundwater flow directions and gradients; • Remedial operations (using the VE/GASS) at the Site have been effective in removing ' fuel hydrocarbons from the subsurface and in controlling migration of the groundwater fuel hydrocarbon plume, evidenced by COCs being reported as non - detect for a minimum of six (6) quarters at MW -2 and MW -5. Note: Prior to that, only sporadic low ' concentrations of COCs were reported and MtBE, DIPE, ETBE, TAME and TBA have not been reported since the August 24, 2005 sampling event; • Fuel hydrocarbon concentrations (BTEX and TPHg) in groundwater had shown ' significant reductions across the Site since startup of the remediation system. However, rebound in dissolved fuel hydrocarbon concentrations have recently occurred in the area of well MW -3; ' • Fuel hydrocarbon mass removed, as of August 2, 2006, was calculated as approximately 176,152 Ibs, or approximately 27,523 gallons; and • The residual COCs in groundwater in the area encompassed by MW -1 and MW -3 ' warrant restart of the existing remedial system. Recommendations E2C makes the following recommendations based on the above conclusions and the data presented in this report: ■ Continue to monitor and sample groundwater at the Site on a quarterly basis; Analyze groundwater samples for BTEX and MtBE using EPA Method 8260b. Note: Although MtBE has been reported as non - detect since August 2005, E2C recommends that analysis for this analyte continue to verify that it does not rebound as high concentrations were originally present in groundwater; however, E2C recommends that analyses for DIPE, ETBE, TAME and TBA be discontinued; ■ Operate the remedial system using a thermal catalytic treatment method; and ' Continue to submit groundwater monitoring reports and remediation status reports to the Client, the RWQCB and the BFD on a quarterly basis. I' E2C Remediation 2 Proiect Number 1 BK2 October 6. ' 1.0 INTRODUCTION ' On April 15, 2008, E2C Remediation (E2C) conducted Second Quarter 2008 groundwater monitoring and sampling at the Minit Stop Market located at 2900 Union Avenue, Bakersfield, California (Site) (see Figure 1). In addition, this report documents the remediation status for the ' Site. This report has been prepared by E2C for Mr. Nassri Jaber to document site conditions as required by the State of California Regional Water Quality Control Board — Central Valley Region, the Lead Regulatory Agency in ongoing directive letters, most recently dated April 19, 2007. ' 1.1 Site Description ' The Site is a Texaco gasoline station and convenience store ( Minit Stop Market) located in Bakersfield, California, at 2900 Union Avenue, on the northeast corner of Union Avenue and Pacific Street (see Figure 1 for Site Location Map). The Site is located within the southwestern ' quarter of the southwestern quarter of Section 20, Township 29 South, Range 28 East, and MDBM. The Site is at an elevation of approximately 428 feet above Mean Sea Level (msl) and the topography is relatively flat with a slight slope to the southwest. The Minit Stop facility consists of a convenience store and a canopy- covered fueling area consisting of one fueling island located west of the building. The lot covers an area of approximately 14,950 square feet with one (1) structure of approximately 2,000 square feet in the east center of the parcel. Formerly located at the Site were three (3) 10,000 — gallon gasoline USTs, and four (4) multiple product dispensers (MPDs) on a single dispenser island (also, two 5,000 - gallon gasoline USTs were abandoned in place). The former USTs were located to the north and east of the present fueling area. Currently present at the Site are a 20,000 - gallon, doubled - walled, split- chambered UST and two (2) dual -sided MPDs on a single dispenser island, with the 15,000- gallon chamber used to store regular unleaded gasoline and the 5,000 — gallon chamber used to store premium- unleaded gasoline. The surrounding area consists of mixed industrial, commercial and residential uses along Union Avenue. The sites directly adjacent to the subject property are described below: • North: Located adjacent to the subject site is a service shop (Air - Draulics Sales and Service); • South: Pacific Street bounds the Site to the South and beyond is a general contractor (Silver AC & Heating); • East: An alley bounds the Site to the East and beyond is a single - family residence; and ■ West: Union Avenue bounds the Site to the West and beyond are a canal and a storage warehouse (Kern Ice & Cold Storage Co.). 1.2 Site Geology and Hydrology 1.2.1 Site Geology The property is located in the south central area of the San Joaquin Valley where the Sierra Nevada, Great Valley, and Coastal Range physiographic provinces meet. The southern end of the Sierra Nevada Province is composed of a massive block of igneous and metamorphic rock of Mesozoic age and older. This Sierran block, 40 to 100 miles wide and 400 miles long, slopes five to seven degrees beneath the San Joaquin Valley. The Coastal Range province on the west consists of tectonically deformed and fractured marine and non - marine sedimentary rocks of Jurassic, Cretaceous, and Tertiary age, which dip eastward beneath the San Joaquin Valley. The Great Valley province is a broad asymmetrical synclinal trough, which is known as the E2C Remediation Project Number 1603BK26 October 6. 2008 Sacramento Valley in the north and the San Joaquin Valley in the south. Beneath the southern San Joaquin Valley floor, the Sierran plutonic and metamorphic rock block is overlain by consolidated marine rocks of Jurassic and Cretaceous age. These rocks are overlain by continental marine and non - marine sedimentary rocks of Tertiary age, which are comprised of continental deposits of consolidated to semi - consolidated, fossiliferous sandstone, siltstone, and shale which thicken toward the south and west. The Tertiary rocks in turn, are overlain by unconsolidated continental deposits, which consist of Pliocene to Holocene river and lake sediments of gravel, sand, silt, and clay. Surface features of the floor of the San Joaquin Valley consist of dissected uplands, alluvial fans, overflow areas, and lake bottoms. Dissected uplands lie between the mountains and the nearly flat Valley floor and are manifest in low -lying hills through which perennial and intermittent streams flow. These features consist of reworked older alluvium. The alluvial fans are the sites of active stream deposition of sands and sifts derived from the Sierra Nevada and the dissected uplands. The overflow lands and lake bottoms lie in the central part of the Valley where silt and clay accumulate in quiet lake and marsh environments. The Site lies in the northeast portion of the City of Bakersfield on a geomorphologicai feature ' loosely termed "the Panorama Bluffs ". The Panorama Bluffs achieve an elevation of approximately 900 feet mean sea level (MSL) and slope to the south - southwest. The Panorama Bluffs are a slightly tilted (uplifted) erosional remnant of the deposition along the ' Kern River. The Kern River is located just north of the Bluffs at its base. The depositional environment of the bluffs is alternating between high - energy deposition (gravel, cobbles, and boulders) and low- energy deposition (silts and clays in overbank deposits). The subsurface beneath the Site is characterized by interbedded silt, clayey silt, silty to clayey sand, and sand with gravel and clay lenses. Beneath the Site, dense layers of gravel to cobbles of weathered granite exist between depths of approximately 50 feet and 75 feet below ground surface (bgs). Off the Site, in the downgradient direction at the location of MW -5, dense layers of gravels to cobbles of weathered granite exist between 30 feet and 75 feet, and between 90 feet and 105 feet bgs, with a layer of fine to medium grain size sand (SP) between them. 1,2,2 Site Hydrogeology A broad, thick hydrogeologic unit consisting of soil and rock with varying porosity and permeability underlies the Central Valley of California. Physical dimensions are approximately 50 miles wide at the widest point in the Valley, 400 miles long, and as much as 2,000 feet deep. Recharge to regional aquifers consists of infiltration of seasonal precipitation and percolation of surface waters. The Valley aquifer of greatest storage, highest quality, and greatest accessibility for domestic and agricultural use consists of the alluvial and lacustrine continental deposits extending to the depths of 1,500 to 2,000 feet beneath the San Joaquin Valley floor. Lithologic and hydraulic properties of these sediments are largely the product of the sediment source and the depositional environment. The sediments range in size from clays to boulders and include all mixtures between the extremes. Western sediments are derived largely from the Coastal Ranges, and tend to consist of shales and fine sandstones with limited permeability. Eastern sediments are derived mainly from granitic materials of the Sierra Nevada, and are generally coarser and much more permeable. Sediments encountered during the borings at the Minit Stop site consisted of alluvial and fluvial deposits of interbedded silt, clayey silt, silty to clayey sand, and sand with gravel and clay lenses. Dense layers of E2C Remediation 4 POW Number 1803BK26 October 6 2008 permeable, weathered granite gravel and cobbles exist between depths of approximately 50 feet and 75 feet bgs. Regionally, the depth to groundwater ranges between 200 and 220 feet below grade, according to the 1996 Water Supply Report published by the Kern County Water Agency in July 2000. During February 2002 drilling activities, first encountered groundwater was found at a depth of approximately 120 feet bgs. During January 2003 drilling activities, first groundwater was also encountered at a depth of approximately 120 feet. During July 2003 drilling activities, first groundwater was also encountered at a depth of approximately 119 feet bgs. See Table 3 for a summary of historical groundwater elevations. 1.3 Summary of Site History On March 18, 1999, the City of Bakersfield Fire Department (BFD) (lead agency for the Site) issued a temporary closure permit for the Site. The underground storage tank upgrades had not been completed and temporary closure was in effect as of that date. In March 2000 a Phase I Environmental Site Assessment was performed. H In May 2000, three (3) 10,000- gallon USTs', and four (4) multiple product dispensers (MPDs) on a single dispenser island and associated product piping were removed as follows. ■ Tank #1 — 10,000 - Gallon Gasoline (Removed - May 9, 2000) ' ■ Tank #2 — 10,000 - Gallon Gasoline (Removed - May 9, 2000) ■ Tank #3 — 10,000 - Gallon Gasoline (Removed - May 9, 2000) ' Upon removal of the above tanks, two (2) additional 5,000 - gallon USTs were discovered to the east of the three 10,000 - gallon USTs. The two (2) 5,000 - gallon USTs were abandoned in place in accordance with KCEHD guidelines and KCEHD permitting. ' • Tank #4 — 5,000 - Gallon Gasoline (Abandoned in place) ■ Tank #5 — 5,000 - Gallon Gasoline (Abandoned in place) ' At the time of tank removal, soil samples were collected from beneath the inverts at each end of the USTs. Soil samples were also collected beneath each MPD. Three (3) hand -auger soil borings (TK -4W, TK -5W, and TK -5E) were also slant - drilled beneath the inverts of the two (2) 5,000 - gallon newly discovered USTs, with soil samples collected at depths of 12 and 16 feet bgs in each boring. ' Elevated concentrations of adsorbed -phase Total Petroleum Hydrocarbons as gasoline (TPHg) and the volatile aromatic compounds of benzene, toluene, ethyl benzene and total xylenes (BTEX) were reported in soil samples at location TK -3E at depths of 14 and 18 feet bgs ' beneath the eastern end of the southern 10,000 - gallon gasoline UST, and in soil sample TK- 4W-16 which was collected at a depth of 16 feet bgs beneath the western end of the western 5,000 - gallon USTs. The maximum concentrations for TPHg and BTEX were reported at location TK -5E at the eastern 5,000 - gallon UST. Trace concentrations of benzene and the fuel ' oxygenate of methyl tertiary-butyl ether (MtBE) were reported in soil sample TK -3E -14 collected at a depth of 14 feet bgs beneath the eastern end of the southern 10,000 - gallon UST, but were reported as non - detect at the 18 -foot depth at that same location. TPHg, BTEX, and MtBE ' were reported as non - detect in the remaining twenty -three (23) soil samples analyzed. The fueling facilities were subsequently upgraded with a 20,000 - gallon double - walled, split chamber UST and two dual -sided MPDs on a single dispenser island. II E2C Remediation 5 Project Number 1 B03BK26 October 6. 2008 1.3.1 Site Assessment Status Groundwater Monitoring Wells To date, five (5) groundwater monitoring wells have been installed, four (4) onsite (MW -1 through MW -4) and one (1) offsite (MW -5). See Figure 2 for the monitoring well locations. Vapor Extraction and Air Sparge Wells Three (3) double - completion (two separate screen intervals, shallow and deep) vapor extraction (VE) wells and one (1) deep completion VE well have been installed at the Site. Four (4) groundwater air sparge (AS) wells have also been installed. Vapor Extraction Pilot Test Conclusions A VE Pilot Test was conducted in March 2003. The site stratigraphy and lack of resistance to flow (0.4- to 1.45- inch H2O at different wells) suggested that this site was an ideal candidate for vapor extraction. The extremely high removal rates documented also suggested that this site had a significant soil and groundwater on -site source (i.e., area requiring remediation). It was calculated that the radius of influence for a full -scale remediation would be at a minimum 55 feet, and could exceed 70 feet. It was found that the use of well VE -3S tended to dilute the influent vapor stream and should only be used during the initial stages of remediation. Use of VE-1S and VE-1D yielded the highest influent concentrations, thus the focus of remediation would be at these two (2) wells after 100% of the well field became utilized. Note: VE-1S and VE-1D are located in the highest source area of soil and groundwater impaction. Therefore these wells would yield the highest removal rates. It was estimated that hydrocarbon removal rates initially could be greater than 1,000 Ibs/day, with a subsequent decrease as remedial operations progressed. Surrounding Area Well Survey Research of the surrounding area identified six (6) water supply wells and two (2) surface water bodies within a 2,500 -foot radius of the Site. 2.0 GROUNDWATER MONlrOR/NG .. Depths to groundwater were measured and groundwater samples were collected from site monitoring wells as part of Second Quarter 2008 monitoring event. The depths to groundwater were used to calculate groundwater elevations and interpret the groundwater flow direction and gradient. The groundwater samples were chemically analyzed to evaluate groundwater chemical conditions. 2.1 Second Quarter 2008 Groundwater Monitoring On April 15, 2008 E2C conducted Second Quarter 2008 groundwater monitoring and sampling at the Site. 2.1.1 Groundwater Elevation Monitoring Each well (MW -1 through MW -5) was evaluated, using a clear bailer, for the presence of free- ' product, and none was identified. The depth to groundwater was then measured at each well to the nearest one - hundredth (0.01) of a foot, using a Solinst water level indicator. Measurements were made at the north side of the top of casing. The Solinst water level indicator, and attached measuring tape, were washed in Alconox solution and were then double rinsed in clean potable water prior to use at each well. Depth to groundwater measurements are summarized in Table 1 and with historical data in Table 3. 1 E2C Remediation Proiect Number 1803BK26 _ October 6 Based on the April 2008 measurements, the overall groundwater elevation decreased an average of 2.54 feet in the Second Quarter 2008, as compared to the First Quarter 2008 and ' groundwater flow was interpreted as southeasterly at a gradient of 0.025 ft/ft (see Figure 3). The groundwater flow direction and gradient were consistent with historic interpreted flow directions and gradients. Note: Groundwater flow and gradient beneath the Site may be influenced by recharge from the nearby canal. The canal is unlined and parallels Union Avenue along its west side. Stream flow in the canal is southerly. 2.1.2 Groundwater Sampling Methods and Procedures Groundwater at all monitoring wells. was purged using a battery- operated pump or a hand bailer. At least 3 casing volumes of groundwater was removed from each well prior to sampling. Casing volume is calculated by multiplying the height of the freestanding water ' column in the well by the cross - sectional area of the well casing. The temperature, pH and conductivity of the water were measured periodically as water was pumped from the wells to ensure sufficient purging, as indicated by stable measurements on field instruments. At each well, when measurements from the field instruments stabilized to within 10% of the previous ' measurement during purging, groundwater in the well was considered representative of the aquifer, a groundwater sample was collected. A purge data sheet for each well is included in Appendix A. Each groundwater sample was collected using a new disposable bailer. Liquid in the bailer was decanted into two 40- milliliter volatile organic analysis (VOA) vials. Each sample container was sealed using a tight fitting Teflon -lined screw cap. Care was taken so that no headspace or bubbles existed after sealing each VOA with the cap. All samples were labeled and documented on a chain of custody record immediately after sealing. After the documentation was complete, the samples were placed into an iced cooler maintained at 4° Centigrade for transport to the analytical laboratory. All downhole equipment was cleaned prior to use by washing with an Alconox solution and double rinsing clean potable water. 2.1.3 Recycling of Purge Water Groundwater sampling purge water was transported to Remedy Environmental Services of Bakersfield, California for recycling. Transport manifests and recycling certificates are presented in Appendix C. 2.1.4 Groundwater Analytical Services Groundwater samples were transported under Chain -of- Custody and were analyzed at ProVera Analytical Laboratories, Inc. (ProVera) (California State - Certified analytical laboratory #2606) in accordance with State guidelines and EPA protocols. The samples were analyzed for the following fuel hydrocarbons using the appropriate EPA Method: • BTEX using EPA Method 8260b; • The fuel oxygenates of MtBE, di- isopropyl ether (DIPE), ethyl tertiary-butyl ether (ETBE), tertiary-amyl methyl ether (TBA) and tertiary-butyl alcohol (a.k.a. tert- butanol) (TBA) using EPA Method 8260b; • TPHg using EPA Method 8015M; and • The reporting limits for BTEX and the fuel oxygenates were 0.5 µg/L (TBA at 2.5 µg /L) and 50 gg /L for TPHg. E2C Remediation Proiect Number 1803BK26 October 6. 2008 2.1.5 Summary of Second Quarter 2008 Groundwater Analytical Data A summary of reported concentrations in groundwater samples follows: ■ Benzene was reported as non - detect in all wells (See Figure 4); ■ TPHg was reported at two (2) wells (MW -1 and MW -3), at concentrations of 1,630 ltg /L ' and 1,490 gg /L, respectively(See Figure 5); • Toluene was reported at one (1) well, at a concentration of 27.3 gg /L at MW -3; ■ Ethylbenzene was reported at one (1) well, at a concentration of 39 gg/L at MW -3; ' ■ Xylenes were reported at one (1) well, at a concentration of 79.8 gg /L at MW -3; and ■ MtBE, TBA, DIPE, EtBE, TAME, 1,2 -DCA and EDB were reported as non - detect in all groundwater samples collected this quarter. 2.1.6 Quality Control Samples ' The duplicate sample collected from well MW -2 was .reported to contain similar or identical concentrations of COCs as the primary sample from that well. The trip blank was reported as non - detect for any of the COCs at their respective detection limits, and the laboratory control samples all had recoveries within acceptable ranges. These results indicated that the analytical data are usable and are of adequate quality and reproducibility to satisfy data validity requirements. 2.2 Compliance with AB 2886 Groundwater analytical data for this quarter have been uploaded to the GeoTracker data base in accordance with State of California Assembly Bill 2886 (AB 2886). Groundwater elevation data have also been uploaded to the data base. Finally, a copy of this status report has also been uploaded to the data base. Appendix D contains copies of the available upload confirmation reports through the Second Quarter 2008. Any upload confirmation reports not included in this report will be included in the next quarterly status report. 2.3 Discussion of Groundwater Monitoring Data The groundwater flow, direction and gradient in the Second Quarter 2008 were consistent with interpreted historic flow directions and gradients. In the Second Quarter 2008 dissolved -phase COCs were reported as non - detect at well MW -1, except for TPHg being reported at a concentration of 1,630 gg /L at that well. At the, upgradient (somewhat cross - gradient) monitoring well (MW -4), fuel constituents of concern (COCs) of benzene, toluene, ethylbenzene and xylenes (BTEX) and Total Petroleum Hydrocarbons as gasoline (TPHg) have been reported as non - detect for twelve (12) consecutive quarters. Similarly, at MW -2, located downgradient and cross - gradient to the southwest, COCs have been reported as non - detect for fifteen (15) consecutive quarters. At MW -1, the Source Area monitoring well, COC concentrations rebounded slightly in the First and Second Quarters 2008. In July 2007, COCs rebounded slightly at MW -3, however, have shown a declining trend since that time (see Table 3) and at the furthest downgradient well (MW -5), sporadic low concentrations of dissolved -phase COCs were reported prior to August 2005. Since that time, all COCs have been reported as non - detect at that well. 1 E2C Remediation Proiect Number 1803BK26 October 6 2008 This data indicates that remedial operations at the Site had been effective in reduction of `source' mass in the Source Area vadose zone and in reduction of dissolved -phase components in groundwater throughout the Site; however, it appears that rebound in dissolved phase COCs have recently occurred in the area of well MW -1 with significant residual concentrations (that continue to show a decreasing trend) still present in the area of MW -3. Additionally, the moderate concentrations of COCs at MW -3 indicate that a groundwater `source' mass occurs in the area between MW -1 and MW -3 and may extend somewhat downgradient from MW -3; however, migration offsite has not progressed any great distance, as COCs are non - detect at MW -5. Note: 1,2- Dichloroethane (1,2 -DCA) and 1,2- Dibromomethane (a.k.a. ethylene dibromide) (EDB), were reported as non - detect in groundwater at the Site since December 2004. The analysis for 1,2 -DCA and EDB were discontinued per the RWQCB letter dated December 21, 2006. Additionally, the five fuel oxygenates of methyl tertiary -butyl ether (MtBE), di- isopropyl ether (DIPE), ethyl tertiary-butyl ether (ETBE), tertiary-amyl methyl ether (TBA) and tertiary- butyl alcohol (a.k.a. tert- butanol) (TBA) have been reported as non - detect at all wells since August 2005. 3.0 REMEDIATION STATUS REPORT During the period of April 9, 2004 through August 6, 2006, remedial operations at the Site were conducted using combined vapor extraction/ groundwater air s ar in system VE/GASS . 9 P 9 P 9 9 Y ( ) The groundwater air sparging components performed two (2) functions: 1) increased dissolved oxygen in groundwater to enhance microbial degradation processes, and 2) mechanically stripped hydrocarbons (volatilization process). Upon volatilization, the hydrocarbons rose and were collected via the vapor extraction system. The vapor extraction system also removed ' hydrocarbons from the vadose zone. Extracted hydrocarbons were then routed in a vapor stream to a thermal treatment unit. Extraction of the hydrocarbons occurs via remediation wells consisting of three (3) multiple - completion vapor extraction (VE) wells (VE -1 D/1 S, VE- 2D /2S, and VE- 3D /3S)], one (1) deep completion VE well (VE -4), and four (4) air sparge wells (AS wells) plumbed to manifolds located in the onsite equipment compound. See Figure 2, Site Plan, for the location of the AS ' wells, VE wells and the onsite remediation equipment compound. In September 2003, the SJVAPCD issued the Permit to Operate (PTO) for the remedial equipment. On April 29, 2004, after the installation gas and electrical services by PG &E, the remediation system (utilizing a Baker Furnace 250 -CFM Thermal Oxidizer (BF 250) for effluent vapor treatment), was brought on line. On April 26, 2006, the system was switched over to Thermal /Catalytic mode for the treatment of effluent vapors. The system operated in Thermal /catalytic mode until August 20, 2006. The remediation system was to be modified to treat effluent vapors using granular activated carbon (GAC). However, the rebound of I' dissolved COC concentrations in 2007 precludes the efficient use of GAC at this time. A description of remedial systems operations is presented below. 1 3.1 Remedial System Operations — Thermal Oxidizer Mode For initial site remediation, E2C utilized the BF 250, which was designed to be modified in the field for use with a modular catalytic cell when fuel hydrocarbon concentrations declined and Istabilized at or below 2,000 parts per million by volume (ppmV). The unit's minimum operating II EC Remediation Project Number 1803BK26 October 6 2008 temperature in thermal mode was 1,400 deg. F, and its minimum operating temperature in catalytic mode was 600 deg. F. These temperatures were set to ensure cost effective vapor oxidation. The unit was equipped with a positive displacement (PD) vapor extraction blower. For improved reliability and safety, the valve controls, actuators, and components were controlled by a relay logic system. The unit was equipped with a water knockout pot, automatic air dilution, a noise - reducing muffler, and a blower sound reducing enclosure. This equipment was designed to shut down and lock out in the event of a system malfunction. The various safety features included sensors to detect high and low oxidizer bed temperatures, high and low blower pressure, high intake LEL, high and low air pressure, high and low exhaust temperature, and water knockout malfunction. The manufacturer's specifications for this remediation unit indicate that this unit has 99% (minimum) destruction efficiency. During remediation system operations, the remediation equipment was typically monitored on a weekly basis to perform routine maintenance, to record oxidizer parameters (temperature, flow rate and operating hours), to measure and document influent and effluent hydrocarbon concentrations and to optimize the wellfield. Although the oxidizer parameters were continuously recorded digitally on a Zip disk, weekly monitoring of these parameters verified continued accuracy of the measuring devices. Hydrocarbon concentrations were measured with a portable hydrogen flame ionization detector (FID) and the data is used in applicable formulas to calculate hydrocarbon mass removal rates (on both a monthly and on a cumulative basis). Adjustments were continually made to the configuration of the unit to maximize vapor flow from the wellfield, while maintaining the chamber temperature above 1,400 degrees Fahrenheit ( °F) (as required in the SJVAPCD permit) and keeping the chamber temperature below the manufacturer's recommended temperature limit of 1,850 OF in the stack. The wellfield was optimized on a weekly basis (i.e., control valves are opened and closed to achieve the highest influent concentration possible). Due to declining influent concentrations, E2C instituted a cycling program to promote fuel hydrocarbon rebound, which resulted in improved efficiency in removal costs. E2C cycled the thermal unit off for the periods of October 31, 2005 through November 11, 2005 and November ' 28 through December 12, 2005. E2C continued to enhance rebound by cycling the thermal unit off from February 7, 2006 through March 6, 2006. It should be noted that as of July 2007, the rebound of dissolved COC concentrations was ' sufficient to warrant restarting the existing remedial system. The RWQCB in verbal communication with E2C concurred with this conclusion. As such, E2C restarted the remedial system using thermal catalytic treatment on August 22, 2008, 3.2 Remedial System Operations - ThermaXatalytic Mode In early March 2006, influent concentrations remained low even after numerous cyclic optimizing episodes. These low levels of extracted influent were not cost effective for continued use of the thermal unit. As such, E2C notified the SJVAPCD of the intention to convert the thermal unit to a thermal /catalytic unit. During the remainder of March 2006, and through most of April 2006, the thermal unit was cycled off and modified for thermal /catalytic operation, which commenced on April 20, 2006. The system was operated in thermallcatalytic mode until August 2006 when it was found that influent concentrations had reduced to levels that precluded efficient continued use of the thermal /catalytic unit on a full -time run basis. Therefore, on August 2, 2006, the system was shut down pending an evaluation of the system efficiency and to determine if any modifications could be made to the system to enable more efficient operations. E2C Remediation . 10 Proiect Number 1803BK26 October 6. 2008 Prior to shutdown on August 2, 2006 the previous two (2) months of operational influent laboratory analytical data indicated influent concentrations that averaged approximately 500 ppmV, with an average flow of approximately 175 SUM, which equated to a removal rate of approximately 24 to 33 Ibs /day (approximately 850 Ibs /month). Additionally, system cycling data indicated, that following periods of shutdown, influent concentrations were lower than pre - shutdown levels and on system restart after off- cycling periods, influent concentrations would initially be high, however would rapidly decline. Finally, it was found that costs to operate this system at these levels of influent were extremely disproportionate per pound of hydrocarbon removal and did not match up to cost per pound of removal as indicated at other nearby sites undergoing remediation. The utility costs (electricity and natural gas) necessary to operate that system averaged $6,000.00 per month, which equated to approximately $38.00 per gallon of fuel removed. As these energy costs seemed extraordinarily high, E2C contacted PG &E on two (2) occasions to have PG &E verify these seemingly excessive costs and to verify that their lines were not leaking. After extensive conversations with PG &E, PG &E affirmed that there were no leaks in their lines and that their invoices were properly billed. E2C also performed extensive testing to verify that there were no leaks in the site remedial system plumbing and the BF 250 and associated equipment. None were found. Based on the above data, continued full -time use of the BF 250 in thermal /catalytic mode was deemed infeasible. E2C then performed an evaluation to see if an electrical /catalytic oxidizer unit could be utilized, which would eliminate the supplemental fuel costs, thus making the remedial operation more efficient and more cost effective. Based on the influent concentrations over the last few months of BF 250 operations, the concentrations were at the low end of the range needed for efficient use of an electric /catalytic (ECAT) oxidizer. At the time it appeared the expense necessary to meet the permitting requirements for the ECAT would not be justified by the limited ECAT run time that could be expected prior to modification of the remedial system to a granular activated carbon system (GAC) absorption system, which would be used near the end of remedial operations to polish residual fuel hydrocarbons. Although, it was found that carbon change -outs would occur frequently during the initial stages of GAC operations, a GAC remedial system would be substantially more cost effective than operation of either the BF 250 or the ECAT. 3.3 Proposed Remediation System Modifications using Granular Activated Carbon In E2C's report Fourth Quarter 2006 Groundwater Monitoring and Remediation Status Reports, dated January 18, 2007, it was recommended that the existing remediation system be modified to operate using GAC for effluent control. The RWQCB, with their letter dated April 13, 2007, approved the request for modification of the system. A brief description of proposed modifications to the remediation system is presented below. Note: It should be noted that dissolved COC have rebounded to high enough concentrations that the efficient use of GAC is not possible at this time. Based on current dissolved COC concentrations, operation of the remedial system using thermal treatment is the most appropriate measure until dissolved COC concentrations once again decrease. However, the discussion presented below is applicable to the time when dissolved COC concentrations are again low enough to warrant the proposed use of GAC. E2C Remediation 11 Proiect Number 1803BK26 October 6.2008 VE/GAC The proposed new emissions control unit will consist of a vapor phase granular activated carbon treatment unit (see Figure 7 for VE/AS /GAC Process Flow Diagram). The equipment is skid mounted and consists of an entrainment liquid separator, float switches and entrainment water pump, electrical control panel with main power switch and hour meter, vacuum pump and motor, two (2) 1,000 lb. carbon canisters in series filled with granulated activated carbon, one (1) 1,000 lb. carbon canister held in reserve, direct read flow meter, influent and effluent sampling ports for each carbon canister. The units are designed to achieve 100% adsorption efficiency. The calculated removal rate at startup, based on a flow rate of 140 scfm and influent concentration of 600 ppmV, is 27 pounds per day. Influent concentrations are likely to be much lower at the time that GAC is actually utilized for vapor treatment. E2C will operate and monitor the GAC system in accordance with the conditions stipulated in a (SJVAPCD) PTO to verify that emissions are within the permitted limits. It is anticipated that the remediation system will be restarted after a modified PTO is received from the SJVAPCD and after the carbon vessels are installed at the Site. Carbon Change -Out Based on the removal rate of 27 pounds per day, the initial calculated carbon utilization rate is 135 to 189 pounds per day. This calculation is based on an approximate carbon utilization rate of 5 to 7 pounds of 5/8 — inch coconut - shell vapor phase carbon per pound of hydrocarbon. This is calculated from carbon isotherms. Projected breakthrough of the first 1,000 -pound carbon canister is, therefore, between 5.3 and 7.4 days (10.6 to 14.8 days for 2,000 Ibs). As such, it is estimated that carbon (2,000 lbs) will require changing twenty -four (24) times in a one -year period, which is not an efficient or cost effective use of GAC. The estimated GAC usage will be re- calculated at the time GAC is actually utilized. As influent concentrations are expected to be much lower at that time, daily removal rates will also be much lower, thereby extending GAC usage time. Carbon usage can also be extended by reducing influent flow rates. 3.3.1 Air Sparge Compressor Groundwater air sparging was and will be conducted via an Ingersol -Rand 10 -hp air compressor. Needle valve flow controllers, which are set in an air sparge manifold at the equipment compound, control the airflow to the microporous sparge points set at the bottom of the AS wells. Flow of air is optimized during each weekly site visit so that the maximum air pressure available is introduced evenly to all AS wells and into the groundwater. 3.4 Compliance with SJVAPCD Permit To Operate Ongoing San Joaquin Valley Air Pollution Control District (SJVAPCD) Permit To Operate (PTO) compliance has been demonstrated during regular Site visits by measuring the VOC concentrations in the influent and effluent streams, using a PID or FID and collection and chemical analyses of TedlarO bag samples. Based on TedlarO bag data from January 2005 until August 2006, the system destruction has averaged 99.99% (see Tables 6 and 7 for summaries of TedlarO bag influent and effluent laboratory data), which meets PTO conditions. ' Field records, including sampling results, cumulative runtime, flow rate and catalytic oxidizer temperature, were and will be maintained and retained for a minimum of two (2) years. System operation temperature was maintained at a minimum of 1,400 degrees Fahrenheit ( °F) in the combustion chamber of the thermal oxidizer through March 7, 2006. II E2C Remediation 12 Proiect Number 18MK26 _ _ October 6. 2 On March 7, 2006, E2C, submitted a Vapor Extraction System Modification Notif ication (PTO # S- 4205 -1 -0) to the SJVAPCD. E2C notified the SJVUAPCD that the BF 250 unit would be ' modified to operate in thermal /catalytic mode due to decreasing influent concentrations at the site. The modified unit incorporated a catalytic cell and the minimum operating temperature for the combustion chamber of the thermallcatalytic oxidizer was maintained at or above 600 degrees Fahrenheit. On April 20, 2006, thermal/catalytic operations commenced and were terminated on August 2, 2006. At the time the remedial system will be modified to use CAC for the treatment of effluent vapors, an application will be made to the SJVUAPCD to modify the existing PTO to meet the requirements of the SJVAPCD. 3.5 Fuel Hydrocarbon Mass Removal Rates The first method to calculate mass removal rates uses a straight -line extrapolation of influent ' measurements based on actual hourly run-time. Based on this method, the mass of fuel hydrocarbons removed from startup through August 2, 2006 can be calculated at approximately 171,315 Ibs (see Table 4A). The second method to calculate mass removal uses the average ' influent concentrations over the average daily run -time per month. Based on this method, the total mass of fuel hydrocarbons removed from startup through the August 2, 2006 can be calculated at approximately 180,990 Ibs (see Table 5). The average of the above two (2) methods (176,152 Ibs) provides a conservative estimate of the total mass removed. 3.6 Discussion of Remedial Efficiency VE /GASS operational data indicated that influent concentrations to the system declined to a point that did not justify operating the thermal/catalytic unit in the continuous mode. After restart of the thermal /catalytic unit on April 20, 2006, the influent concentrations, based on ' Tedlar@ bag data, declined to less than 1,000 ppmV, even in the cycling operational mode. E2C conducted several cycling events of varying duration, and influent concentrations failed to rebound, as follows: ' • 10/31/05 (Influent = 2,350 ppmV) to 11/11/05 (Influent = 1,850 ppmV); ■ 11/28/05 (Influent = 1,589 ppmV) to 12/12/05 (Influent = 1,825 - declined to 1,000 ppmV); and ' ■ 2/7/06 (Influent = 2,850 ppmV) to 3/3/06 (Influent = 4,450 ppmV — declined to 512 ppmV) The declining influent concentration combined with the excessive energy costs indicated that use of an oxidizer unit was no longer efficient, or cost effective for the Site. 4.0 CONCLUSIONS Based on the site assessment work, groundwater monitoring data and remedial operational data obtained at the Site to date, E2C concludes the following: ■ The average groundwater elevations beneath the Site decreased an average of 2.54 feet in the Second Quarter 2008. The groundwater,flow directions were southeasterly, which were consistent with historic groundwater flow directions and-gradients; ' • Remedial operations (using the VE/GASS) at the Site have been effective in removing fuel hydrocarbons from the subsurface and in controlling migration of the groundwater ' fuel hydrocarbon plume, evidenced by COCs being reported as non - detect for a E2C Remediation 13 Proiect Number 1803BK26 October 6 2008 minimum of six (6) quarters at MW -2 and MW -5. Note: Prior to that, only sporadic low concentrations of COCs were reported and MtBE, DIPE, ETBE, TAME and TBA have not been reported since the August 24, 2005 sampling event; Fuel hydrocarbon concentrations (BTEX and TPHg) in groundwater had shown significant reductions across the Site since startup of the remediation system. However, rebound in dissolved fuel hydrocarbon concentrations have recently occurred in the area of well MW -3; Fuel hydrocarbon mass removed, as of August 2, 2006, was calculated as approximately 176,152 Ibs, or approximately 27,523 gallons; and The residual COCs in groundwater in the area encompassed by MW -1 and MW -3 warrant restart of the existing remedial system. 5.0 RECOMMENDATION'S E2C makes the following conclusions based on the above conclusions and the data presented in this report: ■ Continue to monitor and sample groundwater at the Site on a quarterly basis; • Analyze groundwater samples for BTEX and MtBE using EPA Method 8260b. Note: Although MtBE has been reported as non - detect since August 2005, E2C recommends . that analysis for this analyte continue to verify that it does not rebound as high concentrations were originally present in groundwater; however, E2C recommends that analyses for DIPE, ETBE, TAME and TBA be discontinued; • Operate the remedial system using a thermal catalytic treatment method; and • Continue to submit groundwater monitoring reports and remediation status reports to the Client, the RWQCB and the BFD on a quarterly basis.
