Remediation (E2C) has prepared this No Further Action Request (NFAR) report for the Minit Stop Market (Site) located at 2900 Union Avenue in Bakersfield, California (see Figure 1). The Regional Water Quality Control Board — Central Valley Region (RWQCB) document Appendix A — Reports, TO — Regional Board Staff Recommendations for Preliminary Investigation and Evaluation of Underground Storage Tanks Sites dated April 16, 2004 was used in preparing this NFAR. The purpose of the NFAR report is to provide a document upon which a regulator may make an objective decision regarding the requested closure of the site. 1.1 Current Site Conditions and Site History 1.1.1 Current Site Conditions 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 underground storage tanks (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.). ' 1.1.2 Site History Based on a review of available documents, a summary of the Site history follows. ' On March 18, 1999, the City of Bakersfield Fire Department (BFD) 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. ' The Eldorado Bank retained DCI Services to perform a Phase I Environmental Site Assessment on the subject property located at 2900 Union Avenue. The purpose of this due diligence ' investigation was to assess the subject property for evidence of hazardous waste contamination E2C Remediation 3 Proiect Number 1803SK29 October 9. 2009 and the possibility of underground storage tanks, in a effort to minimize the subject property owner's exposure to liability pursuant to Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). A records review and environmental database survey of the subject site and surrounding sites was performed. In addition, a site reconnaissance survey was conducted on March 2, 2000. DCI reported that based on prior site usage, interviews with the owners and persons knowing past history, review of available records, and a physical site inspection, it did not appear that hazardous substances had impaired the subject site. DCI further reported that the underground storage tanks had passed a leak detection test performed in 1998. However, underground storage tank upgrades had not been completed and temporary closure was in effect. DCI further stated that the owner had contracted with an underground tank company to perform the necessary work to bring the site into compliance with current regulations. 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. E2C Remediation Proiect Number 1803SK29 October 9. 2009 1.1.3 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 (Le., 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 VEA S and VEA D 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 -1 S and VE -1 D 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 pounds per day (lbs /day), with a subsequent decrease as remedial operations progressed. 1.2 Site Geo logy 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 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 silts 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. E2C Remedlation 5 Proiect Number 1803BK29 October 9. 2009 The Site lies in the northeast portion of the City of Bakersfield on a geomorphological 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 Boring Logs and Cross - Sections Copies of the boring logs are included in Appendix A. Copies of the cross - sections and the cross - section transect plot are included in Appendix B. 1.3 Site Hydrogeo/ogy 1.3.1 Site Hydrogeo/ogy 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 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. ' Historical groundwater flow at the Site has been interpreted as generally southeasterly at moderate gradients, approximating 0.020 to 0.035 ft/ft. These conditions were interpreted for the Second Quarter 2009 (see Figure 3). ' EzC Remediation 6 PPr fact Number 1803BK29 October 9. 2009 ' 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. ' 1.3.2 Groundwater Elevations and Depths to Water Site - speck hydrogeologic characteristics show depths to groundwater levels have ranged from approximately one hundred eleven (111) to one hundred twenty -nine (129) feet bgs (see ' Table 1 for summary of historical groundwater elevation data). Groundwater elevations in wells have been used to estimate groundwater flow directions. 1.4 Sensitive Potential Receptors 1.4.1 Wells Research of the surrounding area identified six (6) water supply wells within a 2,500 -foot radius of the Site. Descriptions of each well are provided as follows: Well CWS 22 -02 is located approximately 2,350 feet west - southwest of the Site at 706 Espee Street (northeast corner of Espee and "Q" Streets). According to the CWS, the well has been non - operational since April 2002 due to water quality problems caused by high iron and manganese concentrations. The well was located during the field reconnaissance and was non - operational at that time. Well CWS 33 -02 is located approximately 2,150 feet northeast of the Site at 522 33`d Street. Total depth of the well is 600 feet and the casing is 16 inches diameter decreasing to 12 inches diameter. The well is pumped at a depth of approximately 320' feet though according to the CWS it has been non - operational for several years due to high iron and manganese contents in the water. The well was located during the field reconnaissance and was non - operational at that time. Well CWS 34-02 is located approximately 2,100 feet north - northeast of the Site at 317 34"' Street. Total depth of the well is 600 feet and the casing is 16 inches diameter. The well is pumped at a depth of approximately 320 feet though according to the CWS it has been non- operational since 2000 due to high iron and manganese contents in the water. The well was located during the field reconnaissance and was non - operational at that time. Well CWS 58 -01 is located approximately 2,500 feet northeast of the Site at 267 Bernard Street (across from Green Frog Market just west of the southwest corner of Bernard Street and Alta Vista Drive). According to the CWS, the well has been non - operational since 1991 or 1992 due to high iron and manganese contents in the water. The well was non - operational during the field reconnaissance. Well CWS 78 -01 is located approximately 1,900 feet south - southeast of the Site at 1030 Sacramento Street (southwest corner of Sacramento and Lake Streets). According to the CWS, the well is approximately 600 feet deep and has a sanitary seal to a depth of 50 feet. The well has been taken out of service due to high iron and manganese contents in the water. The well was observed to be non - operational during the field reconnaissance. Well CWS 140 -01 is located approximately 1,900 feet southwest of the Site at 503 Espee Street (just south of the Highway 178 overpass). According to the CWS, the well has a total depth of 825 feet. Well screen interval data was not available. The depth to water during pumping was last measured in 2002 at a depth of 220 feet and according to the CWS production superintendent, this likely represents a drawdown of about 20 feet. Production from this well in 2002 was 801 acre -feet of water (approximately 261 million gallons). This E2C Remediation Project Number 1803BK29 October 9. 2009 represents a pumping rate of approximately 500 gallons per minute (gpm) based on continuous pumping during 2002. The water is piped to storage tanks located at the intersection of Mount Vernon Avenue and Bernard Street and is used for domestic purposes. There is currently no water quality issues associated with this well according to the CWS. The well was operational during the field reconnaissance. 1.4.2 Surface Water Research of the surrounding 'area identified two (2) surface water bodies within a 2,500 -foot radius of the Site. There are two unlined canals located west of Union Avenue across from the Site. The nearest canal, the East Side Canal, is located approximately 25 feet west of Union Avenue and trends north -south in the Site vicinity. The canal passes into a culvert on the north side of Niles Street that turns east - southeast into an unlined section of the canal that runs parallel to Lake Street. The second canal, the Kern Island Canal, is located approximately 600 feet west of and trends sub - parallel to Union Avenue. The canal passes into a culvert on the north side of Niles Street that runs beneath Highway 178 and continues southward past Golden State Avenue (Highway 204). Water was observed to be flowing in both canals during the field reconnaissance. 1.5 Site Areas of Impact ' At the Site, the detected impact to soil and groundwater are as follows: Soil: ' Soil impact was first discovered during tank removal operations. The date the discharge began and the source and the cause of the discharge is unknown. Fuel hydrocarbons were detected in soil from 14 to 18 feet below ground surface (bgs) during tank removal operations in May ' 2000 as follows: • Eastem end of southern 10,000 gallon tank; • Western 5,000 gallon tank; ' • Eastern 5,000 gallon tank; and 0 Western end of western 5,000 gallon tank. In January 2001 additional site characterization was performed. Concentrations of TPHg were reported in all samples analyzed from boring B -1 at concentrations ranging from 2,000 milligrams per kilogram (mg /Kg) to 6,300 mg /Kg. Concentrations of benzene and MtBE were reported in samples from B -1 ranging from 3.7 mg /Kg to 10 mg /Kg and 34 mg /Kg to 480 mg /Kg, respectively. Analytes were reported as non - detect in samples from boring B-2, analyzed to a depth of 35 feet bgs, and boring B -3, analyzed to a depth of 50 feet bgs. The lateral extent of hydrocarbon- impacted soils was not established due to drilling refusal at borings B -2 and B -3 at 50 feet bgs. Selected soil samples collected during February 2002 from soil borings B1 -RD, 62 -RD, B3 -RD, and B -4 were chemically analyzed. A summary of the concentrations of detected analytes follows: TPHg was reported in samples collected from soil boring B1 -RD at a maximum concentration of 1,610 mg /Kg at a depth of 110 feet bgs; however, TPHg was previously reported by Holguin, Fahan and Associates, Inc. at a maximum concentration of 6,300 mg /Kg at a depth of 30 feet bgs adjacent to this location; TPHg was reported in samples collected from borings B2 -RD, 133 -RD, and B -4 at a maximum concentration of 9.75 mg /Kg at B3 -RD at a depth of 102 feet bgs; Benzene was reportedly only detected in samples from boring 131 -RD at a maximum concentration of 58.8 mg /Kg; and EzC Remediation 8 Proiect Number 1803BK29 October 9. 2009 • MtBE was reportedly detected in samples from boring B1 -RD at a maximum concentration of 138.9 mg /Kg, B3 -RD at a maximum of 4.2 mg /Kg, and B -4 at a maximum of 8.2 mg /Kg. MtBE was reportedly not detected in samples from 132 -RD. Fuel hydrocarbons were detected in soil samples collected during January and February 2003 at depths ranging from 20 to 125 feet bgs during the drilling of MW -2 through MW-4 and VE -1 through VE -3. Fuel hydrocarbons were detected in July 2003 in soil from 90 to 120 feet bgs during the drilling of AS -1 and AS -2. Tables 2A and 2B summarize historical soil sampling data for the Site. Historical impact to soil is depicted in a plan view map and cross - sections that are presented in Appendix C. Appendix C, Figure 10 depicted the approximate lateral extent of fuel hydrocarbon impacted soils beneath the Site. Impacted soils occurred over an area of approximately 7,500 square feet (sf), as depicted on Appendix C, Figure 10. The thickness of the impacted soils varied based on location. Appendix C, Figures 11A through 12B depict cross - sections of the Site that showed approximate extent of impact at depth. Appendix C, Figures 11A and 11B depicted TPHg and MtBE impacts, respectively, along Cross- Section A -A'. Appendix C, Figures 12A and 12B depicted TPHg and MtBE impacts along Cross - Section B -B'. Based on available data, approximately 22,000 cubic yards of fuel hydrocarbon- impacted soils were estimated to have occurred beneath the Site with the degree of impaction varying dependent upon location and distance from the source area, which appears to be located near well MW -1. Groundwater: E2C initiated groundwater monitoring at the Site by sampling well MW -1 on February 19, 2002. TPHg, MtBE, and total xylenes were reported in MW -1 at concentrations of 380 µg /L (390 µg /L in duplicate), 1,570 µg/l_ (1,770 µg /L in duplicate), and 130 gg /L (140 "/L in duplicate), respectively. Benzene, toluene, and ethylbenzene were reported as non - detect in the samples. Subsequently, monitoring was performed on a quarterly basis through April 2009. Historical groundwater monitoring data for the Site is summarized in Table 3. 1.6 Volume of Excavated Soil Soil excavation did not occur at the Site. 1.7 Fate of Monitoring Wells Five (5) groundwater monitoring wells (MW -1 through MW -5) are present at or near the Site. Each of these wells were monitored and sampled on a quarterly basis through the Second Quarter 2009. Additionally, four (4) air - sparge wells (AS -1 through AS-4) and four vapor extraction wells (VE -1 S -1 D, VE- 2S -2D, VE- 3S -3D, and VE-4) are also present at the Site. 1.8 Tabulated Analytical Results Historical soil analytical data is summarized in Tables 2A and 2B. Historical groundwater monitoring analytical data for the Site are summarized in Table 3. Summaries of influent and effluent vapor analytical data are presented in Tables 6 and 7. 1.9 Concentrations and Mass Changes over Time Concentrations of constituents of concern (COCs) in groundwater have shown dramatic decreases over time, such that in April 2009 all COCs were reported as non - detect. A comparison plot of historical MtBE concentration trends at MW -1, MW -2 and MW -3 from May 2002 to April 2009 is presented in Figure 6. E2C Remediation 9 Project Number 1803BK29 October 9, 2009 1. 10 Current Extent of Groundwater Impact The most recent groundwater analytical data from April 22, 2009, are depicted on plots included as Figures 4 and 5 and are summarized following: • Benzene was reported as non - detect in all wells (See Figure 4); • TPHg was reported as non - detect in all wells (See Figure 5); and • Toluene, ethylbenzene, xylenes, MtBE, tertiary butyl ether (TBA), di- isopropyl ether (DIPE), ethyl tertiary butyl ether (ETBE), and tertiary amyl methyl ether (TAME) were reported as non - detect in all groundwater samples collected this quarter. 1.11 Remedial Methods This Section presents a summary of the remediation status of the site. 1.11.1 Summary of Historical Remedial Actions During the period of April 9, 2004 through August 6, 2006, remedial operations at the Site were conducted using a combined vapor extraction /groundwater air sparging system (VE/GASS). 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-1D/1S, 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 San Joaquin Valley Air Pollution Control District (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 dissolved COC concentrations in 2007 precluded the efficient use of GAC at that time. A description of remedial systems operations is presented below. 1.11.2 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 ' stabilized at or below 2,000 parts per million by volume (ppmV). The unit's minimum operating 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, E2C Remediation 10 Proiect Number 1803BK29 October 9. 2009 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. 1.11.3 Remedial System Operations - Thermal /Catalytic 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 operations that are more efficient. 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 SCFM, 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 E2C Remediation 11 Proiect Number 1803SK29 October 9. 2009 ' 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 could 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. However, as of July 2007, the rebound of dissolved COC concentrations was sufficient to warrant restarting the existing remedial system using the catalytic treatment mode. E2C restarted the remedial system using thermal catalytic treatment on August 22, 2008 and continued through June 5, 2009. Note: Electrical difficulties plagued the remediation system in the Second Quarter 2009. Initially, the blower motor for the soil vapor extraction (SVE) portion of the remediation system burned out in early May 2009. The blower was subsequently replaced and the remediation system was restarted in late May 2009. However, on June 5, 2009 the remediation system shut down again. E2C determined that the motor starter burned the contactor to the groundwater air sparging system (GASS) compressor. E2C made numerous attempts in June and July 2009 to fix the 'GASS compressor. Ultimately, a licensed electrical contractor fixed the remediation system. The SVE portion of the remediation system operated cyclically from August 28 to September 4, 2009 and from September 14 to September '18, 2009, primarily to evaluate influent vapor rebound. The GASS operated continuously from August 28 to September 18, 2009. Based on groundwater analytical data from March 6 and April 22, 2009, it appears that the remedial system using thermal catalytic treatment has reduced COC concentrations in groundwater to non - detect in all wells. 1.11.4 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 and from August 22 to September 18, 2009 were calculated at approximately 178,848 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 1 startup through the August 2, 2006 and from August 22 to September 18, 2009 were calculated at approximately 186,115 Ibs (see Table 5). The average of the above two (2) methods (182,482 Ibs) provides a conservative estimate of the total mass removed. ' E2C Remediation 12 Prolect Number 1803BK29 October 9. 2009 1.11.5 Evaluation of Influent Vapor Rebound Two periods of remedial operations utilizing soil vapor extraction (SVE) and groundwater air - sparging (GASS) occurred at the Site, from April 9, 2004 through August 6, 2006 and from August 22, 2008 to June 5, 2009. From April 9, 2004 through August 6, 2006, the SVE/GASS operated for 12,011.6 hours. During this period of operation, field influent vapor concentrations averaged 5,790.6 parts per million by Volume (ppmV), decreasing from approximately 50,000 ppmV on April 9, 2004 to 540 ppmV on August 6, 2006. Laboratory influent vapor concentrations averaged 2,106.7 ppmV from January 31, 2005 to July 24, 2006 (See Table 4A). An estimated 173,133 pounds (Lbs) of fuel hydrocarbons were removed from beneath the Site during this period of operations at a removal rate of 14.4 pounds per hour (Lbs /hr). A significant mass of fuel hydrocarbons were removed during this first period of operation. From August 22, 2008 through June 5, 2009, the SVE/GASS operated for 4,580 hours. During this period of operation, field influent vapor concentrations averaged 568.8 ppmV, decreasing from 2,850 ppmV on September 5, 2008 to 35 ppmV on June 5, 2009, when the SVE/GASS was turned off. Laboratory influent vapor concentrations averaged 676.5 ppmV from August 25, 2008 to September 22, 2008 (See Table 4A). An estimated 5,714 Lbs of fuel hydrocarbons were removed from beneath the Site during this period of operations at a removal rate of 1.25 Lbs /hr. The SVE portion of the remediation system operated cyclically from August 28 to September 4, 2009 and from September 14 to September 18, 2009, primarily to evaluate influent vapor rebound. The GASS portion of the remediation system operated continuously from August 28 to September 18, 2009. During this period of operation, extensive monitoring data were obtained. SVE/GASS operating parameters (operating hours, flowrate, destruction chamber and stack temperatures) were recorded, and field influent/effluent hydrocarbon concentrations were measured and recorded (field measurements are summarized in Table 4A). Additionally, hydrocarbon concentrations were measured in the field with a portable flame ionization detector (FID). Influent and effluent vapor samples were collected almost daily via Tedlar® bags during the August and September 2009 rebound monitoring period to assist in verification of fuel hydrocarbon removal rates. These vapor samples were chemically analyzed for the following COCs using the appropriate EPA Method: ■ TPHg using Modified EPA Method TO -3; and I , BTEX, 1,2- dichloroethane (1,2 -DCA), ethylene dibromide (EDB) and MtBE using EPA Method TO -15. ' The detection limits utilized are as follows: ■ 0.1 ppmV for Modified EPA Method TO -3; and ■ 0.01 ppmV for EPA Method TO -15. Note: Although not required to assess hydrocarbon t rebound, EDB was analyzed at a much lower detection limit of 0.53 parts per billion by volume (ppbV) due to its extremely toxic nature. n Influent vapor analytical data from August and September 2009 indicated that benzene, 1,2 -DCA and EDB were non - detect and TPHg, toluene, ethylbenzene, xylenes and MtBE were reported at very low concentrations. Influent vapor analytical data are summarized in Tables 6 E2C Remediation 13 Project Number 1803BK29 October 9. 2009 and 8, while effluent vapor analytical data are summarized in Table 7. Copies of influent and effluent vapor analytical reports for August and September 2009 are presented in Appendix D. From August 28, 2009 through September 18, 2009, the SVE/GASS operated for.293 hours. During this period of operation, field influent vapor concentrations averaged 28.4 ppmV, ranging from a high of 35 ppmV on September 3 and 4, 2009 to a low of 10 ppmV on September 14, 2009. Field influent vapor concentrations were never higher than the 35 ppmV measured on June 5, 2009 when the SVE/GASS was previously turned off. Laboratory influent vapor concentrations averaged 1.844 ppmV from August 29, 2009 to September 17, 2009 (See Table 4A). Based on laboratory data, an estimated 0.978 Lb of fuel hydrocarbons were removed from beneath the Site during this period of operations at a removal rate of 0.0036 Lb /hr. Based on the influent vapor data from August and September 2009, hydrocarbons did not rebound and soil beneath the Site appears to have been effectively remediated. As such, the continued operation of the SVE/GASS is not warranted. 1.12 Remaining Mass in Soil and Groundwater Soil Analytical results of the August and September 2009 influent vapor sampling (See Section 1.11.5), indicate that fuel - related hydrocarbons were either non - detect (benzene, 1,2 -DCA and EDB) or detected at very low concentrations (TPHg, toluene, ethylbenzene, xylenes and MtBE) (See Table 8). Based on this data, little or no hydrocarbon mass remains in vadose zone soil beneath the Site. Groundwater Based on recent groundwater analytical results in which all COCs in groundwater were reported as non - detect, it appears that little or no hydrocarbon mass remains in groundwater at the Site. If COCs had been detected in groundwater, then the residual mass of COCs in groundwater could be calculated using the following formulas: • Volume = Length X Width X thickness of water - bearing column X 7.34 gallons /cubic foot = gallons; • Residual mass in pounds = gallons *3.28 liters /gal *influent (Ng /L) /1,000,000 pg /gram *l lb/454 grams; and ■ Concentration = total of COCs in highest concentration well. 1.13 Risk Assessments Since benzene was reported as non - detect in groundwater at all groundwater monitoring wells at the Site in March and April 2009 (See Table 3) and was also reported as non - detect in influent soil vapors during September 2009 (See Tables 6 and 8), a Tier 2 risk assessment is not required. 1.14 Fate and Transport Modeling Fate and transport modeling is not applicable for this Site because all COCs have been reported as non - detect in groundwater. 1.15 Water Quality and Human Health impact ' Recent fuel hydrocarbon analytical data for groundwater was compared to water quality numerical limits adopted by the RWQCB to assess water quality and human health impact. The most recently available groundwater analytical data for TPHg and selected fuel ' E2C Remediation 14 IPPr iect Number 1803BK29 October 9. 2009 hydrocarbon constituents (March 6 and April 22, 2009 and earlier for some constituents) are compared to water quality numerical limits in Table 9 and as follows: TPHg ' TPHg was reported as non - detect (< 50 µg /L) in all groundwater monitoring wells on March 6 and April 22, 2009.

However, as individuals are not drinking groundwater at this location, human health is not being impacted. Lead Lead was reported as non - detect (detection limit of 0.05 pg /L) in groundwater monitoring._well MW -1 on December 9, 2002. Water quality numerical limits for lead were not exceeded. 1.16 List of Technical Reports A list of Technical reports is presented in Appendix F. 1.17 Additional Comments Supporting Site NFAR Remedial efforts at the Minit Stop Market Site have been highly effective. This is supported by all COCs being reported as non - detect in groundwater in the First and Second Quarters 2009. Additionally, based on August and September 2009 influent vapor analytical data, rebound has not occurred and little or no hydrocarbon mass remains in soil beneath the Site. Based on these data, the site warrants case closure and No Further Action. Note: Upon approval of this NFA Request, E2C will prepare a Site Decommissioning Workplan for RWQCB review and approval. After approval of the Workplan, E2C will obtain the necessary permits, after which, E2C will mobilize to the Site and properly abandon the monitoring and remediation wells in accordance with State and Local Agency guidelines. E2C will also decommission the remaining remediation system appurtenances and demobilize them from the Site. Upon completion of the Site Decommissioning activities, a Site Decommissioning Report of Findings will be submitted as the final step in obtaining the NFA Letter.
