California Dear Mr. Hardin: This report summarizes the progress of the ground water recovery system and vapor extraction system (VES) activities for July 1996 through December 1996 at the former Navy Oil Company Lease site in Bakersfield, California. Enclosed are three copies, one for your file, one to forward to Mr. Brian Pitts at the Kern County Department of Environmental Health Services (KCDEHS), and one to forward to Mr. Howard Wines at the City of Bakersfield Fire Department, Office of Environmental Services. Key activities included monthly monitoring and maintenance of the VES and ground water recovery system, and ground water monitoring. 1.0 INTRODUCTION 1. Figure 1 (attached) shows the ground water recovery system and the VES. 2. Fuel hydrocarbons are being extracted from the vadose zone through four vapor extraction wells (E-l shallow [E-IS], E-l deep [E-ID] and E-2 and E-3). The fuel vapors are destroyed in a thermal oxidizer permitted by the San Joaquin Valley Air Pollution Control District (SJV APCD). Samples of vapor from each extraction well are collected monthly to track the progress of the YES. The monthly monitoring indicates that over the second half of 1996, the VES is extracting and burning on the average of approximately 98 pounds of hydrocarbons per day. 3. Ground water impacted with low levels of dissolved phase fuel constituents (benzene, toluene, xylene and ethylbenzene [BTXE]) is extracted from two ground water monitoring wells, MW -4 and MW -7. The extracted ground water is pumped into a holding tank and then discharged into the city industrial sewer under an Industrial Wastewater Discharge (IWD) Permit issued by the City of Bakersfield Public Works Department. The effluent is sampled semiannually for IWD Permit compliance and parameter concentrations have consistently been below permit limitations. Approximately 90,350 gallons of ground water have been extracted and discharged from July through December 1996. @ . . . TIIC Environmental Solutions Inc. Mr. Mick Hardin February 5, 1997 Page 2 2.0 GROUND WATER MONITORING 1 . Semiannual sampling and gauging of seven monitoring wells onsite were completed on December 19, 1996, and included the following activities: · Measurement of depth to ground water. · Measurement of thickness of free product, if present. · Sampling and analysis of one sample from each monitoring well for volatile fuel hydrocarbons (VFH), extractable fuel hydrocarbons (EFH), and BTXE by United States Environmental Protection Agency (EPA) Methods 80l5M/8020. Figure 1 shows the locations of the onsite monitoring wells. VOLUME OF GROUND WATER RECOVERED 1 . Table 1 provides a summary of the volume of ground water pumped from MW -4 and MW -7 during the second half of 1996. Approximately 90,350 gallons of water were discharged into the industrial sewer from June 28, 1996 through December 19, 1996. To date, approximately 236,150 gallons of water have been recovered from ground water pumping activities. 2. The flow meter on the inlet of the ground water storage tank failed on December 19, 1996, and was replaced on January 2, 1997. GROUND WATER AND PRODUCT MEASUREMENTS 1 . On December 18 and 19, 1996, depth to ground water and free product thickness were measured in MW-2, -3, -5, -6, and -8. Ground water levels were not measured in MW -1, -4 and -7 since MW -4 and MW -7 are fitted with recovery pumps and MW -1 is within an area used by the City of Bakersfield for stockpiling rubble and debris and was not accessible (i.e., covered with rubble). 2. Table 2 summarizes the historic water level and product thickness data. Free product was not detected in the monitoring wells, however an oily sheen and a hydrocarbon odor were present in samples taken from MW-2, -4, and -7. Generally, ground water elevations were approximately 0.97 feet higher than the previous monitoring event in June 1996. GROUND WATER OUALITY 1. Ground water samples collected from MW-2, -3, -4, -5, -6, -7 and -8 were analyzed for BTXE by EPA Method 8020, and for EFH and VFH by EPA Method 8015M. The results are summarized in Table 3. The laboratory reports and Chain-of-Custody fonns are included in Attachment A. @ . ,. . TIIC Environmental Solutions/ne. Mr. Mick Hardin February 5, 1997 Page 3 2. Analytical results for Monitoring Wells MW-3, -5, -6 and -8 show EFH, VFH and BTXE concentrations have consistently remained below detection. 3. Monitoring Wells MW-2, -4, and -7 previously contained free product floating on the ground water, but remediation activities have removed the free product and only an oily sheen was observed in each of these three wells. Analytical results indicate that dissolved phase EFH, VFH and BTXE concentrations in MW-2, -4 and -7 have decreased significantly over the last five quarterly monitoring events. IWD PERMIT COMPLIANCE SAMPLING 1 . Samples of ground water discharged into the city sewer were collected on December 19, 1996, and analyzed for the parameters required by the IWD Permit. 2. On November 26, 1996, Ms. Lara Kimm and Mr. Timothy Ryan from the City of Bakersfield Wastewater Division performed their annual inspection of the site. They observed the ground water storage tank and reviewed sample collection procedures. On December 19, 1996, Ms. Lara Kimm observed the collection of the samples for IWD Permit compliance. 3 . The analytical results indicate that the effluent parameters are within the IWD Permit limitations. A copy of the laboratory reports were forwarded to the City of Bakersfield ' Public Works Department and to the KCDEHS. A copy of the last monitoring report submitted to the City of Bakersfield is included in Attachment B. 3.0 V APOR EXTRACTION SYSTEM 1 . The YES is monitored monthly to ensure the equipment is operating properly and to monitor the progress of remediation. Photoionization detector (Pill) readings of influent and effluent volatile organic compound (VOC) concentrations indicated that the thermal oxidizer was operating within the parameters of the SJV APCD Permit limits. PERFORMANCE TRACKING 1 . Pill readings and flow rates from each of the four extraction wells are summarized in Table 4. The PID readings are used for field-tracking of hydrocarbon levels in the soil vapor. 2. YES vent well vacuum measurements are summarized in Table 5. The results show vacuum levels in the vent wells which indicate the YES is effective to the perimeter of the soil plume. 3 . Vapor samples were collected from the four extraction wells on a monthly basis to track the fuel hydrocarbon levels in the soil vapor and to also calculate the number of pounds of hydrocarbons destroyed. The samples were analyzed by a state-certified laboratory , (¡) . . . TIIC Environmental Solutions Inc. Mr. Mick Hardin February 5, 1997 Page 4 and the results are shown in Table 6. The laboratory reports are included in Attachment C. The samples were tested for the following parameters: · VFH: EPA Method 8015M · BTXE: EP A Method 8020 Based on the VFH analysis results (see Table 6) and the flow from each well (Table 4), the pounds of VOCs destroyed each month since startup on December 7, 1994 are shown below. These results indicate the pounds ofVOCs destroyed per day have decreased from 300 to 400 pounds per day during the first months of startup to less than 100 pounds per day in December. The supporting calculations are shown in Attachment D.

TIIC Environmental Solutions Inc. Mr. Mick Hardin February 5, 1997 Page 5 4.0 SITE CLOSURE STATUS 1 . Site remediation including active ground water removal and soil YES has been ongoing since 1993. To date, all ofthe free floating product has been removed and low levels of dissolved phase hydrocarbons are present in only three of the eight ground water monitoring wells. Additionally, VOC concentrations in the soil gas from the vapor extraction wells have decreased significantly. 2. Based on the current monitoring results, the following verification sampling will be . conducted to evaluate the cleanup status of the vadose zone soil. · The YES will be shut down for approximately one month to allow vapors in the soil to accumulate. · The YES would then be restarted and a soil gas sample collected from each extraction well and analyzed for VOCs. If VOC content is low (i.e., little to no rebound), then the YES would be operated through June 1997 and a verification soil sampling program as described in Chapter 8.0 of the Phase II Remediation Status and Phase ill Remediation W orkplan (December 1993) would be implemented. This program would involve five borings and analysis of several soil samples for total fuel hydrocarbons and BTXE by EPA Methods 8015/8020.IfVOC content is high, indicating an accumulation of soil vapors and a remaining reservoir of fuel that can be removed from the soil mass (i.e., a high degree of rebound), the YES would be restarted and operated beyond June 1997. 3. Verification sampling results would be transmitted under separate cover. Please call if you have any questions. Sincerely, ~~ Tim C. Lassen, P.E.

California Dear Ms. Kimm: This letter summarizes the 1996 effluent monitoring results for July through December 1996 for the discharge located at the Santa Fe Railway Company site at 1433 Union Avenue, Bakersfield, California. The discharge is regulated by Industrial Wastewater Discharge (IWD) Permit No. 2-BK-0020. Pursuant to the IWD permit, headspace is monitored monthly for lower explosive limit (LEL). Samples of the discharged water are collected for laboratory analyses on a semiannual basis and were collected on December 19, 1996. The monthly headspace monitoring results are summarized below and the semiannual analytical results are summarized in Table 1 (attached). The laboratory analysis report is attached and key points are summarized below. · The total volume of ground water discharged from July 1 to December 19, 1996 was 90,350 gallons. · The average discharge per day was 525 gallons (0.0005 mgd), well below the pennitted flow of 0.003 mgd. · The LEL in the headspace of the temporary holding tank ranged from <0.01 percent to 0.<;>3 percent. · As shown in Table 1 (attached), the monitoring parameters did not exceed -the effluent limitations. Pursuant to the IWD Permit, the annual inspection was conducted on November 26, 1996 by representatives of the City of Bakersfield Public Works Department and TRC Environmental Solutions, Inc.
