A TC Pennit #0230001 Dear Mr. Paxson, INTRODUCTION The remediation project at the Favorite Foods facility at 201 Union Ave. in Bakersfield, California is now complete. The last weekly sampling event took place on December 6, 1991 and a request for closure report was submitted to the Kern County Department of Environmental Health Services (KCDEHS) on January 6, 1992. The KCDEHS agreed with our request to discontinue vapor extraction at the site and closure is presently. awaiting the submittal of a risk assessment BACKGROUND RESNNGroundwater Resources Inc.(RESNA) started construction of the vapor extraction system at the site on June 21, 1991 after receiving an authority to construct pennit (#0230001) from the Kern County Air Pollution Control District (APCD). The equipment was installed and testing of the system was started on June 28, 1991. A four-hour test was performed on July 11, 1991 in which air samples were collected every hour for four hours. During the week following the four-hour test, the system was sampled once a day. On July 22, 1991 an inspection was perfonned by the APCD in which they checked the system for completeness. Verbal approval of the system was given by APCD inspector Mr. Gilbert Navarro. The system ran consistently (24 hours a day) from July 16, 1991 to November 4, 1991, when the system was shut-down for a two-week period to see if vapor concentrations would significantly increase after re-start. MONITORING Initial monitoring indicated a high methane content in the vapor stream causing higher then predicted Lower Explosion Limit (LEL) readings between and after the carbon canisters (see attached field data sheets). An air sample was collected and analyzed to confirm the methane content. Methane has continued to decrease in the vapor stream as the project has progressed. Sampling of the vapor extraction system took place once a week as required by the APCD since the first week. Air samples have been collected in Tedlar bags from the inlet, between the carbon drums, and at the stack to detect concentrations of gasoline and diesel constituents in the vapor MAILING ADDRESS: p, 0, BOX 9383, BAKERSFIELD, CA 93389 (805) 835-7700 FAX (80S) 835-771 7 e Kern County APCD ) . .,' &FJ1ation Quarterly Report March 3, 1992 Page 2 - -"""!JJ:6 J!II! ......"..... stream at these locations. Using both analytical data and field data, the rate of pounds of hydrocarbons extracted has been calculated (see attached tables). The tables present two sets of calculated data; the first is pounds per day extracted based on analytical data from inlet air samples (after dilution, just before passing through the carbon) and pounds per day extracted using analytical data from the extraction well (RW-l, before dilution). These two values show a good correlation. On December 10, 1991 the accumulated pounds extracted were approximately 547 pounds. Inlet air samples analyzed have shown a steady decrease in gasoline vapor content in the extracted air stream. Initial pounds of product extracted were approximately 36 pounds per day, which decreased to 0.94 pounds per day by December 6, 1991. Chart 1, shows this decline in pounds of product extracted per day. Chart 2 shows accumulated pounds of volatile organic compounds (VOC's) extracted. Samples taken from the extraction well (RW-1), inlet port (after dilution), and between 1 & 2 carbon drums have been analyzed by RESNA's gas chromatograph (GC) for Total Petroleum Hydrocarbons (TPH) as gasoline. Selected air samples have been analyzed by both RESNA's GC and by a certified laboratory to ensure that RESNA's GC is giving viable numbers. All stack samples have been analyzed by a certified analytical laboratory. Copies of the certified analytical reports for the last quarter are enclosed for your review. The first granulated activated carbon (GAC) canister was replaced on August 6, 1991, after approximately 347 pounds of VOC's were adsorbed. Elevated Hnu and LEL readings indicated break-through had occurred. The second GAC canister was moved into the first position and the third canister (not used yet) was moved into the second position. Approximately 153 pounds of VOC's were adsorbed in this drum before the initial two GAC canisters were replenished with new carbon on October 8, 1991 and the spent carbon was transported off-site to be regenerated. The final GAC drum adsorbed approximately 47 pounds of hydrocarbons before the system was shut- down. The spent carbon will be transported off-site and regenerated The system was shut-off on November 4, 1991 following a weekly sampling event. The system was restarted on November 19, 1991, and air samples were collected with-in 30 minutes of the re- start Analytical results were compared to past concentrations to see ü hydrocarbon concentrations increased significantly or stayed the same following the shut-down period. Based on RESNA's gas chromatograph, concentrations increased from 0.095 ug/cc to 0.16 ug/cc TPH gasoline. This increase is minimal compared to original concentrations seen at the start-up of the project (38 ug/cc). The system continued to run until December 10, 1991. Two confinnation borings were drilled on December 23, 1991. Analytical results showed that the volatile organic compounds had been removed, but heavy end hydrocarbons remained in-place. A risk assessment dealing with the remaining hydrocarbon plume will be submitted to the KCDEHS shortly. If there are any questions concerning this project please contact me at (805) 835-7700.

A TC Pennit #0230001 Dear Mr. Paxson, INTRODUCTION The remediation project at the Favorite Foods facility at 201 Union Ave. in Bakersfield, Calüornia is currently on schedule. RESNNGroundwater Resources Inc.(RESNA) started construction of the vapor extraction system at the site on June 21, 1991 after receiving an authority to construct permit (#0230001) from the Kern County Air Pollution Control District (APCD). The equipment was installed and testing of the system was started June 28, 1991. A four-hour test was performed on July II, 1991 in which air samples were collected every hour for four hours. During the week following the four-hour test, the system was sampled once a day. On July 22, 1991 an inspection was performed by the APCD in which they checked the system for completeness. Verbal approval of the system was given by APCD inspector Mr. Gilbert Navarro. The system has been running consistently (24 hours a day) since July 16, 1991 with no mechanical problems. MONITORING . Initial monitoring indicated a high methane content in the vapor stream causing higher then predicted Lower Explosion Limit (LEL) readings between and after the carbon canisters (see attached field data sheets). An air sample was collected and analyzed to confirm the methane content. Methane has continued to decrease in the vapor stream as the project has progressed. Sampling of the system has been taking place once a week as required by the APCD since the first week. Air samples have been collected in tedlar bags from the inlet, between the carbon drums, and at the stack to detect concentrations of gasoline and diesel constituents in the vapor stream at these locations. No gasoline constituents have been reported in any of the stack samples analyzed. U sing both analytical data and field data, the rate of pounds of product extracted has been calculated (see attached tables). The tables present two sets of calculated data; the first is pounds per day extracted based on analytical data from inlet air samples (after dilution, just before passing through the carbon) and pounds per day extracted using analytical data from the extraction well (RW-1, before dilution). These two values show a good correlation. As of October 3, 1991 the accumulated pounds extracted were approximately 500 pounds. MAILING ADDRESS: P. O. BOX 9383, BAKERSFIELD, CA 93389 (805) 835-7700 FAX (805) 835-771 7 e e Mr.Thomas Paxson ~ern CQunty APCD CanÜítilln Quarterly Report October 7, 1991 Page 2 --~Æ""::~ Inlet air samples analyzed have shown a steady decrease in gasoline vapor content in the extracted air stream. Initial pounds of product extracted were approximately 36 pounds per day, which has decreased to 0.76 pounds per day as of October 3, 1991. Chart 1, shows this decline in pounds of product extracted per day. Chart 2 shows accumulated pounds of volatile organic compounds (VOC's) extracted. Samples taken from the extraction well (RW-l), inlet port (after dilution), and between 1 & 2 carbon drums have been analyzed by RESNA's gas chrçmatograph (GC) for Total Petroleum Hydrocarbons (TPH) as gasoline. Selected air samples have been analyzed by both RESNA's GC and by a certified laboratory to ensure that RESNA's GC is giving viable numbers. All stack samples have been analyzed by a certified analytical laboratory. Copies of the certified analytical reports are enclosed for your review. The first granulated activated carbon (GAC) canister was replaced on August 6, 1991, after approximately 347 pounds of VOC's were adsorbed. Elevated Hnu and LEL readings indicated break-through had occurred. The second GAC canister was moved into the first position and the third canister (not used yet) was moved into the second position. Approximately 150 pounds of VOC's have been adsorbed in the current first drum as of October 3, 1991. Higher Hnu and LEL readings taken on October 3, 1991 have indicated that the current first GAC canister is close to break-through. The initial two GAC canisters are scheduled to be replenished with new carbon on October 8, 1991 and the spent carbon will be transported off-site to be regenerated Aerobic degradation of diesel constituents in the vadose plume will continue as the more volatile hydrocarbon constituents are extracted. The next quarterly report will be submitted in January, 1992. If there are any questions concerning this project please contact me at (805) 835-7700. Sincerely, . ~fl~ Robert 1.

RE: Carnation/Favorite Foods 201 Union St. Bakersfield, CA Dear Mr.Driggs, Groundwater Resources Inc. (GRl), sampled the soil pile at the above mentioned site on December 20, 1990. A total of eight soil samples were taken from the pile. This is the second sainp1ing event for this soil pile, and the first since spread aeration started. The samples were taken at a minimum depth of 3-inches below the sUIface of the soil. A brass tube was driven into the soil to collect the sample. The samples were sealed, labeled, and put in an ice chest before transport to SMC Laboratories, Bakersfield, CA. under a chain of custody document. Two composite soil samples were analyzed for TPH diesel, oil and grease, and BTXE. Each composite consisted of four samples divided into an N (north) and S (south) section of the soil pile. See Table 1 and enclosures for complete analytical results.

CARNATION, INC. 1.0 INTRODUCTION Groundwater Resources Inc. (GRl), a RESNA company, has prepared this vapor extraction pilot study report forthe Carnation Favorite Foods facility located at 201 Union Avenue in Bakersfield, California (Plate 1). This report details the pilot study results and includes a plan for the full scale vapor extraction system. The plan includes well spacing, vacuum rates, hydrocarbon recovery rates, time required for clean up and vapor treatment technology. The Kern County Air Pollution Control District has been contacted and their pennit applications will be submitted as required. An exemption was obtained from the APCD to perfonn this pilot test. 2.0 BACKGROUND In October of 1987 five underground fuel storage tanks were removed from the above mentioned site (see Plate 2). These included a 3000 gallon fuel oil and diesel tank, a 7,500 gallon gasoline tank, a 1,000 gallon new oil tank, a 1,000 gallon waste oil tank, and a 7,500 gallon diesel tank. Evidence of the removal of a fanner fuel tank was also uncovered and was identified as a phantom tank in previous reports. Soil samples for the preliminary site assessment were collected, as required, from beneath each tank, and the dispenser island. The preliminary site assessment report dated November 2, 1987 was prepared and submitted by William H. Park and Associates (W.H.P.). The analytical results showed hydrocarbon contamination at the fuel oil and diesel tank, at the new oil tank, and at the dispenser island. The other tanks showed no appreciable contamination and no further assessment was needed at those locations. On November 12th and 13th, 1987 a site characterization study was perfonned by W.H.P on the west end of the new oil tank and below the dispenser island (see Plate 2). A total of six test holes were drilled, three test holes at each area, and samples were analyzed for the proper hydrocarbon constituents. Test hole C, drilled at the dispenser island, detected contamination between 10 and 20 feet, with a high of 37,445.96 ppm TPH(diesel) at 15 feet. The other two holes drilled at the dispenser island showed only minor hydrocarbon constituents. All three test holes located near the new oil tank showed oil and grease contamination, with a high of nearly 100,000 ppm at 20 feet in test hole B. These test holes defmed the hydrocarbon plume vertically and laterally and W.H.P. estimated the volume of the plume was about 110 cubic yards of soil. On January 28, 1988 W.H.P. drilled four additional test holes (F,G,H,I) to see if the hydrocarbon plume extended beneath the shop building west of the dispenser island (see Plate 2). Analytical results for test hole F showed 3,696.5 ppm TPH diesel and 7,072.99 ppm TPH gasoline at five feet. Test hole G showed only gasoline contamination of 5,209.76 ppm at five feet. This contamination did not extend past ten fee.t and appeared to be not very extensive (see Plate 6 for cross-section of hydrocarbon plume). MARCH 8, 1991/Page 1 GROUNDWATER RESOURCES INC. e e ....íi- . CARNATION, INC. In their report dated March 30, 1988 W.H.P recommended that the hydrocarbon contaminants near the island dispenser and under the shop building be left in place since it is composed of heavy end hydrocarbons and should not be a threat to the groundwater (estimated to be 200 feet below the surface) or to the public. The other alternative suggested, is to excavate the vadose plumes, but any excavation work would jeopardize the structural integrity of the shop building. Excavated soil from previous work was stockpiled on-site and is currently being aerated. Laboratory results are shown in Tables I and II. On August 30, 1990, ORI submitted a workplan to further assess the soil surrounding the former dispenser island. On September 28 and 29, 1990, ORI drilled two soil bòrings and installed 4-inch diameter schedule 40 PVC casing into one of the borings (ORI-1), for future remediation of the soil by vapor extraction. In a site mitigation report dated December 7, 1990 ORI recommended drilling and installing two more vapor extraction wells near the former diesel dispenser for remediation purposes. On January 10, 1991, two vapor extraction wells were drilled and installed (see Plates 3 through 5 for boring logs). A vapor extraction pilot study was peIformed on the three vapor extraction wells on February 12, 1991. This report details the findings of this vapor extraction pilot study and the full scale vapor extraction system to be used. 3.0 VAPOR EXTRACTION PILOT STUDY, FEBRUARY 12, 1991 3.1 Procedures A150 scfm vacuum pump was used to extract vapors from recovery wells RW-1 RW-2, and ORI-I. Static pressure changes were measured using a manometer attached to neighboring well heads. Air samples were taken periodically to determine vapor concentrations at differing vacuums. An Organic Vapor Analyzer (OV A) was used to monitor vapors before and after entering the four granulated activated carbon drums set up in series. A magnehelic gauge was used to measure vacuums extracted from the well head (in inches of water) and a vacuum gauge measured vacuums in inches of mercury. 3.2 Findings 3.2.1 Field Data Vadose well ORI -1 was tested first. The vacuum extraction system was hooked up to the top of the four-inch casing of ORI-I. Initial flow rates were with RW-2 and RW-1 closed. Vacuum was 4-inches of Hg (mercury) and 60-inches of water. The test on ORI-1, RW-1, and RW- 2 each ran for 20 minutes. One air sample was taken during the testing of ORI-I. The manometer was first hooked up to the top of RW-1 to MARCH 8, 1991/page 2 OROUNDW A TER RESOURCES INC. rv££ OIL "It.

The pressure drop at RW-I increased to 0.8-inches of water after 10 minutes of operation. The manometer was next hooked up to RW-2 and a pressure drop of 0.2- inches of water was recorded after 1 minute, which stabilized at OAO-inches of water after 10 minutes of operation. As shown by Plate 7, the static pressure drops were greatest between RW-I aÌ1d GRI-l. The radius of influence (with 0.25-inch of water pressure drop) is 11 feet in the east-west and 7 feet in the north-south direction. Vapor extraction well R W -1 was tested next and is located in the center of the three spot pattern (including RW-2 and GRI 1). A vacuum of 1.5 inches of Hg was recorded throughout this test. The greatest pressure drop was seen at RW-2 (5.2-inches of water), and the least at GRI-I (O.3-inches of water). Plate 8 shows contours of static pressure drops during this testing of RW-1. Radius of influence calculated for RW-I was 35 feet in the east-west direction and 10 to 12 feet in the north-south direction. One air sample was taken during this test. Vadose well RW- 2 was opened during this test to see if it would change any of the pressures recorded. No appreciable differences were seen with RW-2 open. Vapor extraction well RW - 2 was tested last and showed a pressure drop of 0.8-inches of water at GRI-I and 2A-inches of water at RW -1. Plate 9 shows contours of the static pressure drops observed during the testing of RW-2. Radius of influence was also calculated for RW-2 (see Plate 9 & 10). One air sample was taken during this test. Table 3 shows complete field data collected during this testing. Organic Vapor Analyzer (OVA) readings taken during the vapor ex- traction test of GRI-I were between 400 to 500 ppm before the carbon drums and 2.5 to 100 ppm after the drums. OV A readings taken during the vapor extraction test of RW-I were over 1000ppm before the carbon drums. OV A readings after the carbon drums were 35 to 150 ppm. OVA readings during testing of RW-2 were allover 1000 ppm before the carbon drums and between 100 and 200 ppm after the carbon drums. See Table 3 for fIeld readings.

'.;;-; e e .... CARNATION, INC. 3.2.2 Laboratory Results A total of three air samples were taken during the vapor extraction testing. One from each of the vapor extraction wells. These samples were maintained under a chain of custody document from collection to delivery to SMCLaboratories of Bakersfield, California. These samples were analyzed for BTXE and TPH gasoline and diesel. The highest concentrations were seen in the air sample from RW -1 with a benzene concentration of 1.9 ugm/cc and TPH gasoline concentration of 38 ugm/ cc. For RW-2 the concentrations were 0.0052 ugm/cc benzene and ND (none detected) for TPH gasoline. Analytical results for GRI-l were ND for both TPH gasoline and benzene, but minor concentrations of toluene (0.0068 ugm/cc), total xylenes (0.03 ugm/cc), and ethylbenzene (0.012 ugm/cc) were detected. TPH diesel concentrations were ND for all three air samples analyzed. See Table 4 and Appendix A for complete analytical results.

An average porosity of 40% was detennined in laboratory testing (see Appendix D) and was used in these calculations. With an extraction . flow rate of 100 cubic feet per minute the estimated pore volume turnover rate is every 56.55 minutes or about or 25.5 times a day. See Appendix B for calculations. 3.2.4 Inlet Wells During the vapor extraction testing of R W -1, R W - 2 was uncapped to see what effect this would have on vapor concentrations and pressures at MARCH 8, 1991/Page 5 GROUNDWATER RESOURCES INC. " It e CARNATION, INC. RW-1. No appreciable difference was seen in pressure or in hydrocar- bon vapor concentrations recorded. This data indicates that inlet wells may not be needed at this location. This can be further tested during the actual operation of the vapor extraction system. 4.0 VAPOR EXTRACTION WELLS 4.1 Locations OR! recommends that there is not a need for additional vapor extraction wells at this site. The affected area within the TPH dieseVgasoline soil plume is effectively covered with the three vapor extraction wells already installed at the site. The plume and vapor extraction well radii of influence are shown on Plate 10. 5.0 DESCRIPTION OF TREATMENT SYSTEM The proposed treatment system will process soil vapors utilizing granulated activated carbon (Plate 11). 5.1 (1 h ~~ ~'0~ Treatment of Soil Vapors The soil vapors will be collected from a series of vapor extraction wells using a 2 HP regenerative blower capable of sustaining an average pressure drop of 2 inches of mercury at 100 SCFM. A 100 SCFM blower will evacuate the total pore volume of the soil plume every 169 minutes with all three wells hooked into the system (see Appendix B for calculations). Vapor extraction tests on all vapor recovery wells at the site resulted in vapor concentrations up to 38 ugm/ccTPH gasoline at a flow rate of 50 CFM (see laboratory results, Table 4 and Appendix A). From this data, expected initial concentrations from the vapor extraction system would be ap- proximately 51.24 pounds of product per day. The total volume of diesel and gasoline in the vadose plume is estimated to be 500 gallons or about 3,000 pounds of product. This estimate was calculated using laboratory results and calculated cubic feet of contaminated soil at certain concentrations. Since the majority of the soil contamination is from diesel fuel, there will be non-mobile heavy hydrocarbons that will not be removed by vapor extraction. The goal of this remediation project is to remove the volatile hydrocarbon constituents (BTXE) from the soil and eliminate the threat to biological receptors and to the groundwater beneath the site. The wells will be manifolded together and equipped with individual shut off and air bleed valves. This configuration will allow for individual testing and sampling of each well. Selected individual wells will also be closed or reopened periodically to alter preferred vapor flow paths and provide for more efficient removal of volatiles. Alternating wells can also be used as air intake wells to enhance vapor migration. GROUNDWATER RESOURCES INC. MARCH 8, 1991/Page 6 ,.~~ ' e e CARNATION, INC. The effluent air stream will be injected into vapor phase granular activated carbon (OAC) containers. The adsorption ratio for vapor phase carbon is approximately 20% for diesel and gasoline. An estimated 15,000 pounds of carbon will be used to completely remove the vadose plume. The air stream will be monitored in accordance with the County of Kern Air Pollution Control District pennit require- ments. The OAC will be regenerated as needed with proper manifesting of this material off-site. 5.2 System Monitoring All of the system operations will be controlled by a programmable controller which will be linked via telephone modem to a computer at OR!. The computer will monitor all system operations. 5.3 Equipment Specifications The remediation system will consist primarily of: Two 2000 pound canisters of vapor phase granular activated carbon, model V2OO0, manufactured by Barneby & Sutcliffe Corporation One Programmable Logic Controller, model PC 1200, manufactured by Westinghouse One Rotron Regenerative Blower, model DR 505 AX58, 120 SCFM Equipment perfonnance specifications are presented in Appendix C 6.0 SYSTEM OPERATION The remediation system will be operated on a 24 hour basis. The proposed system has been designed to be flexible and can allow for increases in vapor flow rates if necessary. Compliance sampling of the air emissions will be perfonned on a regular basis as required by the Kern County APCD. A quarterly report containing all of the sampling data (including influent and effluent . concentrations), well head pressure readings, and system operational and maintenance data will be submitted to the Kern County Department of Environmental Health Services (KCDEHS) and the Kern County APCD 7.0 CONFIRMATION OF CLEANUP Confmnation of clean-up in the vadose soil can be accomplished by detennining hydrocarbon concentrations in soil samples from borings or by non detectable concentrations in emissions from MARCH 8, 1991/Page 7 OROUNDW A TER RESOURCES INC. · e ~ CARNATION, INC. various vapor extraction wells. After completion of the remediation project, the wells will be abandoned following KCDEHS guidelines. Estimated time for cleanup of the vadose plume is four to six months.

Processor Power Supply The power supply within the processor pro- vides low voltage DC power for the proces- sor and 1/0 modules. Available I/O Power is: PC 1100 . .. . .. ... . . . ..... 2 Amps PC 1200 or 1250.... . . .. .2.5 Amps Processor Keyswitch The processor keyswitch, a standard feature of Westinghouse 1000 Series programmable controllers, prevents unauthorized program- ming of the processor. When the unit's key is in the RUN position, the processor exe- cutes the user's reference ladder program. The user cannot alter the program when in this mode (unless on-line programming has been selected),; however, the user can moni- tor program operation and change data stored in registers (for example, timer and counter preset values). or force contacts On or Off. In the STOP position, all outputs are dis- abled and the user has full access to modify the ladder diagram andlor register contents. e Descriptive Bulletin , 6·355 Page 3 Memory Utilization The 1000 Series processors use one sixteen- bit word of memory for each contact and for each coil. Nodes, branches, and unused contact positions do not consume any words of memory. This Memory Miser fea- ture of the Westinghouse programmable controllers provides up to 36% better mem- ory utilization than competitive units. On-line Programming The on-line programming option for West- inghouse Programmable Controllers enables the user to enter, delete, and alter a refer- ence ladder diagram while the processor is executing a program (i.e.. Processor Key- switch in RUN position). When program- ming on-line, the user can modify his diagram without disruption to the control operations, thus reducing equipment down- time. A dipswitch located behind the pro- cessor's face plate can be set by the user to select this option. t' () - Descriptive Bulletin 16-355 Page 4 Memory Sizes PC,l100 processor: 1536 words (1.5 K); and 3584 words (3.5 K).

The PC-1200 supports 128 discrete inputs, 128 discrete outputs, 64 register inputs, and 64 register outputs. In addition, the PC-1200 supports 896 internal logic coils and up to 1792 holding registers. Each logic coil may be used as many times in the program as the application requires. The PC-1250 supports 256 discre~e inputs, 256 discrete outputs, 128 register inputs, and 128 register outputs. In addition, the PC-1250 supports 896 internal logic coils and up to 1792 holding registers. Each logic coil may be used as many times in the pro- gram as the application requires. Scan Rate The PC-11 00 processor has a typical scan rate of 7 milliseconds per 1000 words of . memory. The PC-1200 and PC-1250 processors have a typical scan rate of .67 milliseconds per 1000 words of memory. Battery Backup Three AA alkaline cells maintain the CMOS memory of a PC-1100 for a minimum of three months in the event of a power outage. A single AA lithium battery will maintain the CMOS memory of a PC-1200 or PC-1250 for a minimum of one year. Computer Interface Option A second RS-232,C port that is modem compatible is available with the Advanced and Advanced II instruction sets using the Nl-1075B Communications Adapter module.
