7 Fourth Quarter 208 Remediation Progress Report. Introduction On behalf of SFPP, L.P. (SFPP), an operating partnership of Kinder Morgan, Inc. (Kinder Morgan), CH2M HILL Engineers, Inc. (CH2M), now a wholly owned subsidiary of Jacobs Engineering Group Inc. (Jacobs), prepared this report to summarize remediation activities performed at the SFPP Norwalk Pump Station located within the Defense Fuel Support Point (DFSP) Norwalk, at 56 Norwalk Boulevard, Norwalk, California (the site; Figure ) during the fourth quarter 208 reporting period. This progress report is submitted pursuant to a request from the California Regional Water Quality Control Board, Los Angeles Region (Water Board) in its letter dated October 25, 2006 (Water Board, 2006). Additional site background information can be found in the report titled, Conceptual Site Model and Proposed Alternate Interim Remedy for Soil, Groundwater, and LNAPL (CH2M, 203), and in previously submitted semiannual groundwater monitoring reports. This report summarizes the remediation systems present at the site and describes remediation activities for the period of October through December 208 with documentation of the following tasks: Operations and maintenance (O&M) of remediation systems performed by Kinder Morgan field personnel Remediation system evaluation The remediation activities performed from October through December 208 and the progress achieved through those activities are summarized in the following sections.

8 Fourth Quarter 208 Remediation Progress Report 2. Remediation Systems Kinder Morgan operates remediation systems consisting of soil vapor extraction (SVE), total fluids extraction (TFE; extraction of free product and/or groundwater using a top-loading pump), groundwater extraction (GWE; extraction of groundwater using a bottom-loading pump), and treatment of extracted soil vapors and groundwater to address the south-central and southeastern areas of the site. Biosparging is also employed in the south-central area to enhance natural attenuation of hydrocarbon constituents. Operation of the West Side Barrier (WSB) GWE system for remediation of the western offsite area was discontinued in August 2008 based on the reduced lateral extent and low concentrations of volatile organic compounds (VOCs) west of the site. The objectives of the remediation systems are to contain and control the migration of hydrocarbon constituents in groundwater and soil vapor, and to remove hydrocarbon mass from soil and groundwater. The remediation systems include the following wells: South-Central Area 20 TFE wells 24 onsite and 6 offsite SVE wells (most collocated with TFE wells) 2 horizontal SVE wells horizontal biosparge well Southeastern Area (24-inch Block Valve Area) 4 TFE wells (GMW-O-5, GMW-O-8, GMW-36, and GMW-SF-9) 3 SVE wells (collocated with TFE wells) GWE well (GMW-SF-0) A summary of remediation wells in the south-central, southeastern, and WSB areas is presented in Table. Table includes well identifications, well construction details, well function, and operational status at the end of the fourth quarter 208. The remediation system layout is shown on Figure 2. A brief description of each system is provided in Sections 2. through 2.3. Kinder Morgan currently operates three refined fuel pipelines (two 6-inch and one 24-inch) that traverse the southern border of the site. These pipelines previously supplied fuel products to the former tank farm, and various block valves and other connection points were identified as potential sources of subsurface releases in the south-central and southeastern areas of the site. Between the third quarter of 206 and the second quarter of 207, the pipelines were modified to remove all valves and connections so that the pipelines now span across the site in a continuous manner, reducing the potential for future releases that could have occurred at those connection points. 2. Soil Vapor Extraction System SVE is performed using a blower to remove soil vapors from the south-central and southeastern areas of the site. The extracted vapors are conveyed to a knock-out tank that separates entrained moisture from the soil vapors. Accumulated moisture in the knock-out tank is treated by the main groundwater treatment system (GWTS) described in Section 2.2. The soil vapors are then treated in a regenerative thermal oxidizer (RTO) where VOCs are converted to carbon dioxide and water prior to being discharged to the atmosphere. Operation of the GWTS and SVE system is conducted in accordance with Permits to Operate (Permit Number [No.] G4688 A/N and No. G4687 A/N ) issued by the South Coast Air Quality Management District.

9 Fourth Quarter 208 Remediation Progress Report 2.2 Groundwater Treatment System The main GWTS processes free product and groundwater recovered from the south-central and southeastern parts of the site. Free product and groundwater recovered by pneumatically operated, top-loading total fluid pumps and bottom-loading groundwater pumps are piped to a dissolved air flotation (DAF) unit (oil-water separator [OWS]). Free product, if any, from the OWS is collected in a storage tank and recycled at an offsite location. Water from the OWS is treated using liquid-phase granular activated carbon (LGAC). Treated water is routed through an onsite 3,000-gallon equalization tank. Two fluidized bed bioreactors installed downstream of the equalization tank treat fuel oxygenates such as tertiary butyl alcohol (TBA) and methyl tertiary butyl ether (MTBE). The treated groundwater then passes through polishing LGAC units prior to discharge to a storm drain that leads to Coyote Creek. Discharge to Coyote Creek is performed in accordance with a National Pollutant Discharge Elimination System permit (Permit No. CA ; Order No. R ). 2.3 Horizontal Biosparge System In December 205, Kinder Morgan completed installation of a horizontal biosparge system in the south-central area of the site, which consists of a horizontal well and a 500-standard-cubic-foot-perminute (scfm) compressor. To reduce the potential for off-gassing of VOCs during biosparging, the SVE system has an interlock that will not allow the biosparge to operate without the SVE running. The biosparge well is constructed of 4-inch-diameter Schedule 80 polyvinyl chloride (PVC) casing and screen completed to a vertical depth of approximately 45 feet below ground surface. The lateral distance of the screen interval is 600 feet centered below the central portion of the south-central area hydrocarbon plume. Further details regarding the construction of the biosparge well are documented in the report titled, Horizontal Biosparge Well and Soil Vapor Monitoring Probe Completion Report (CH2M, 205). Pilot testing of the biosparge system commenced in early January 206 and continued through October 206. A comprehensive evaluation report that incorporates soil vapor and groundwater data was submitted to the Water Board in August 207 (CH2M, 207). Based on the favorable results of the pilot study, a second horizontal biosparge well was installed in the southeastern area of the site in November 207. The design of the second biosparge well is similar to the south-central biosparge well, consisting of 4-inch-diameter Schedule 80 PVC casing and screen completed to a vertical depth of approximately 45 feet below ground surface. The lateral distance of the screen interval is 240 feet centered below the southeastern area hydrocarbon plume. A construction completion report documenting construction activities and specifications was submitted on July 2, 208 (Jacobs, 208). The 500-scfm sparge compressor was turned off temporarily and a new air sparge compressor (883 scfm) was installed in the fourth quarter 208 to deliver ambient air to both the south-central and southeastern sparge wells. The 500-scfm and 883-scfm compressors are appropriately sized to deliver ambient air to both the south-central and southeastern sparge wells, and to allow for future system expansion. 2-2 AX049234SCO

10 Fourth Quarter 208 Remediation Progress Report 3. Operations and Maintenance During the fourth quarter 208 reporting period, O&M of the remediation systems included the following tasks: Performed ongoing weekly maintenance on the GWTS. Removed, inspected, and repaired existing TFE/GWE pumps and associated discharge lines. Installed pumps and associated equipment necessary for TFE at select wells with measurable free product. Installed the 883-scfm air compressor for the biosparge system in the south-central and southeastern wells. The remediation systems operated continuously during the fourth quarter 208, with the following exceptions: The SVE system was shut down on October 5, 208, due to a high combustion temperature on the RTO. The system was restarted on October 6, 208. The air sparge system was shut down on October 5, 208, to accommodate installation of the new air sparge system. The 883-scfm air sparge system is tentatively scheduled to come online in January 209. The GWTS was shut down from October 22 through November 9, 208, to facilitate gauging and sampling activities during the DFSP second semiannual groundwater sampling event that was conducted November 5 to November 9, 208. The SVE and air sparge systems were shut down from October 22 through November 5, 208, to facilitate gauging and sampling activities during the DFSP second semiannual groundwater sampling event that was conducted November 5 to November 9, 208, and the annual soil vapor sampling event that was conducted from November 2 to November 4, 208. The SVE system, air sparge system, and GWTS were shut down on December 22 to December 3, 208, due to the systems shutting down; the shutdowns were caused by the motors and pressure regulators of the 2007 and 2008 air compressors. The 2007 and 2008 air compressors supply air to the GWTS well pumps and the poppet valves on the RTO. During the fourth quarter 208, the GWTS was operational approximately 6 percent of the time (8 percent of the time excluding planned shutdowns and power outages). The SVE system was operational approximately 6 percent of the time (86 percent of the time excluding planned shutdowns). The biosparge system was operational 28 percent of the time (00 percent of the time excluding planned shutdowns). Table 2 presents the SVE system operation summary. Photoionization detector (PID) measurements and analytical results for extracted vapor during the fourth quarter 208 are summarized in Tables 3 and 4, respectively. The groundwater remediation system operation activities for the fourth quarter 208 are summarized in Table 5. The extracted groundwater analytical results for the fourth quarter 208 are summarized in Table 6. Table 7 presents the biosparge system operation summary. Table 8 presents the soil vapor probe analytical results for November 208. Historical (post-2007) gauging results of select TFE and SVE wells are provided in Table 9. Pre-2007 data can be found in previous semiannual groundwater monitoring reports. Water samples from the GWTS influent were collected on October 23, November 2, and December 4, 208. The water samples were delivered to Asset Laboratories (Asset) of Las Vegas, Nevada, and BC Laboratories, Inc. (BC) of Bakersfield, California, for analysis. Asset and BC are certified by the California Department of Public Health Environmental Laboratory Accreditation Program. Asset analyzed the water samples for VOCs using EPA Method 8260B. BC analyzed the water samples for total petroleum hydrocarbons (TPH) quantified as gasoline (TPH-g), TPH quantified as diesel (TPH-d), AX049234SCO 3-

11 Fourth Quarter 208 Remediation Progress Report and TPH quantified as oil (TPH-o) (collectively referred to as TPH-total) using U.S. Environmental Protection Agency (EPA) Method 805(M). Vapor samples from the SVE influent were collected on October 5, November 20, and December 7, 208. The vapor samples were delivered to Air Technology Laboratories (Air Tech), located in City of Industry, California, for analysis. Air Tech analyzed the vapor samples for the following: Fixed gases (methane, carbon dioxide, oxygen, and argon) using ASTM International (ASTM) D946 VOCs using EPA Method TO-5 Total VOCs using EPA Method TO-3 The laboratory analytical reports and chain-of-custody documents for these samples are included in Appendix A. Soil vapor sampling was conducted from soil vapor probes SVM-, SVM-2, SVM-3, SVM-5 through SVM-8, and SVM-0 through SVM-6 in the south-central area to ensure that shallow subsurface vapors do not pose an unacceptable human health risk to residents in the offsite area south of the site. SFPP s SVE system was shut down on October 22, 208, to allow the vadose zone to reach equilibrium prior to sample collection. The soil vapor probes from each monitoring location were purged and sampled using a vacuum/pressure sampling pump calibrated to a flow rate of 200 milliliters per minute in accordance with recommended flow rates in the Advisory for Active Soil Gas Investigations (DTSC, 205). The American Analytics mobile laboratory conducted these events on November 2 to November 4, 208. Results of these activities are presented in Table 8. A soil vapor sample was not collected at the deep probe of SVM-2 and shallow probe of SVM-0 due to flow restrictions (excessive vacuum) observed during purging activities with a hand-held sampling pump. Soil vapor samples also were not collected from the shallow or deep probes of SVM-4 due to property access restrictions. In accordance with the Advisory (DTSC, 205), field duplicate samples were collected at a minimum frequency of per every 20 primary samples collected. Duplicate soil vapor samples were collected at SVM-7 (3-foot depth), SVM-2 (22-foot depth), and SVM-4R (23-foot depth) during the November 208 event. The duplicate samples were collected and analyzed in the same manner as the primary samples. Ambient air samples were also collected each day of sampling and analyzed by the mobile laboratory for VOCs and TPH-g. The purpose of the ambient air samples is to quantify background concentrations of chemicals of potential concern (COPCs) near select sampling locations. American Analytics analyzed the soil vapor samples for the following: Fixed gases (methane, carbon dioxide, and oxygen) using EPA Method 3CM VOCs using EPA Method TO-5 Gasoline-range organics using EPA Method TO-3 The laboratory analytical reports and chain-of-custody documents for these samples are included in Appendix A. 3-2 AX049234SCO

12 Fourth Quarter 208 Remediation Progress Report 4. Summary of Remediation Progress Based on weekly monitoring of the influent vapor concentration, vapor extraction flow rate, and hours of operation, the total mass of VOCs removed by SVE was 8,958 pounds during the fourth quarter 208. The cumulative mass of VOCs removed since SVE was implemented in September 995 is 3,557,848 pounds (Table 2). The cumulative mass removed by SVE does not include the mass removed by naturally occurring in situ biodegradation. The highest VOC concentration measured with a PID is from the southeastern area SVE wells GMW-36, GMW-O-5, and GMW-O-8 (Table 3). Laboratory analytical data (Table 4) show that the influent VOC concentrations (benzene, toluene, ethylbenzene, and total xylenes [BTEX] and MTBE) decreased slightly from the third quarter 208 to the fourth quarter 208. A total of 544,02 gallons of groundwater was extracted during the fourth quarter 208 (Table 5). No water was extracted from the WSB area during the fourth quarter 208. Approximately 05.4 million gallons of groundwater has been extracted from the south-central, southeastern, and WSB areas since GWTS operations first began in 996. GWE was discontinued in the WSB region during the third quarter 2008 based on the reduced lateral extent and low concentrations of MTBE and,2-dichloroethane (,2-DCA) west of the site.,2-dca, MTBE, and TBA concentrations in the western area during the semiannual groundwater monitoring event conducted in November 208 did not warrant restarting the WSB system. Free product did not accumulate in the product holding tank during the fourth quarter 208. Since 995, a total of 4,426 gallons of product has been removed by TFE, vacuum truck, or manual bailing operations. The estimated mass removal (pounds) of hydrocarbons by the GWTS is shown in Table 5. Mass removal estimates between 996 and 2005 are based on BTEX and MTBE concentrations in the groundwater influent (TPH data were not available) and total volume of extracted groundwater. Mass removal estimates between 2006 and 20 are based on groundwater influent concentrations of TPH-g and TPH quantified as fuel product, and the total volume of extracted groundwater. Mass removal estimates between 202 and the fourth quarter 208 are based on groundwater influent TPH-total concentrations (TPH-total includes TPH-g, TPH-d, and TPH-o) and the total volume of extracted groundwater. Since GWE first began in 996, hydrocarbon mass removed by the GWTS is estimated to be 8,448 pounds. During the fourth quarter 208, the mass removal of hydrocarbons was estimated to be 2 pounds (Table 5). Table 6 shows the extracted groundwater analytical results for the samples collected on October 23, November 2, and December 4, 208. TPH, BTEX, and MTBE concentrations during the fourth quarter 208 were less than the concentrations reported in late 205 and early 206. This reduction in dissolved-phase hydrocarbon concentrations can be attributed to biosparge operations in the south-central area. Appendix B includes time series charts of select wells that show this general decrease in dissolved-phase hydrocarbons in the south-central area. The biosparge system operated for 649 hours in the fourth quarter 208 (Table 7). The biosparge system flow (air injection) rate ranged from 4 to 475 scfm during the fourth quarter 208. Soil vapor samples were collected from 4 locations around the south-central area biosparge well in November 208, but during equilibrium conditions with the SVE and sparge wells off. AX049234SCO 4-

13 Fourth Quarter 208 Remediation Progress Report 5. Soil Vapor Monitoring Results During the fourth quarter 208, soil vapor samples were collected during equilibrium conditions with both the SVE and biosparge systems turned off. Therefore, field VOC measurements with a PID and vacuum measurements were not collected at this time. Soil vapor samples were collected using.4-liter Summa canisters and glass syringes, and were analyzed by the American Analytics onsite mobile laboratory for VOCs using EPA Method TO-5. TPH-g was analyzed using EPA Method TO-3, and fixed gases (carbon dioxide, methane, and oxygen) were analyzed using EPA Method 3CM. Included in the TO-5 list of analytes were BTEX, MTBE, naphthalene, TBA,,2-DCA,,2,4-trimethylbenzene,,3,5-trimethylbenzene, n-butylbenzene, sec-butylbenzene, isopropylbenzene, n-propylbenzene, and 2-propanol (the leak test compound). These constituents were identified as COPCs based on the results of the 2006 soil gas investigation and human health risk assessment (Geomatrix, 2006). 5. Mobile Laboratory Results Table 8 presents the analytical results for samples collected during the November 208 sampling event. Laboratory analytical reports are included in Appendix A. A summary of results is provided below. During the fourth quarter 208 sampling event, COPCs were not detected in any of the offsite and onsite probes. Other non-copcs that were detected during this sampling event included acetone, ethanol, tetrachloroethylene (PCE), and TPH-g. There are no established screening levels for ethanol. The detected concentrations for acetone, PCE, and TPH-g were all below their respective screening levels. AX049234SCO 5-

14 Fourth Quarter 208 Remediation Progress Report 6. System Evaluation and Optimization During the fourth quarter 208, SVE well valves in the south-central area were fully open to ensure maximum vapor extraction from the offsite area. The following repairs were conducted during this reporting period: Hoses were installed in the conveyance piping for groundwater extraction well GMW-O-2 in order to have that well online. Bottom-loading pumps were purchased for wells that currently have short water columns (MW-SF-6, GMW-0, and GMW-O-8). The pumps will be installed and the wells will be put online as soon as the pumps are received. The air injection pump for the DAF unit shutdown due to the pump seizing. The air injection pump was removed and will be replaced. The 2007 and 2008 air compressors were inspected due to frequent shutdowns. The motors and the pressure regulators for both compressors required to be replaced. Installation of the 883-scfm air sparge compressor began on November 7, 208, and it will be turned on in January of 209. The SVE wells in the southeastern area also were fully open to ensure maximum vapor extraction in that area. AX049234SCO 6-

15 Fourth Quarter 208 Remediation Progress Report 7. Planned First Quarter 209 Activities During the first quarter 209, Kinder Morgan plans to continue to focus remedial efforts on the south-central and southeastern areas. The following maintenance and other activities are planned: Continue operation of the SVE system. Test and start up the 883-scfm biosparge compressor and run the south-central horizontal biosparge well using that compressor. Continue with the upgrade of the southeastern SVE wells and conveyance system. Conduct one quarterly soil vapor monitoring event for all soil vapor probes in the south-central area. Measure weekly VOC concentrations as hexane at the influent and effluent of the RTO system. Collect monthly vapor samples at the influent and effluent of the RTO system, and analyze the samples using Methods TO-5 (VOCs), TO-3 (total VOCs as hexane), and ASTM D946 (fixed gases). Continue weekly maintenance and monitoring of the south-central and southeastern SVE and TFE/GWE treatment systems, and the biosparge system. Measure quarterly individual well vapor concentrations with a PID at the manifold. Collect and analyze system influent vapor and groundwater samples. Perform as-needed carbon changeouts of the LGAC vessels. Perform as-needed monitoring and remediation well rehabilitation to remove biofouling and sediment occluding the well screens. Remove, inspect, and repair existing TFE/GWE pumps and associated discharge lines. Install pumps and associated equipment necessary for TFE at select wells with measurable free product. Replace the air injection pump for the DAF unit/ows. Repair the motors and pressure regulators for the 2007 and 2008 air compressor to run both the SVE and the GWTS pumps. The TFE, GWE, and SVE systems for the south-central and southeastern areas will continue to operate. Operation of the TFE system in the southeastern area will be monitored closely and adjustments will be made to improve fluid recovery. The horizontal biosparge system will continue to operate at ideal air flow to decrease product thickness in the south-central area. System inspections will continue on a weekly basis; system evaluation parameters will be collected as needed. The remediation activities and progress for the first quarter 209 will be described in the First Quarter 209 Remediation Progress Report, to be submitted by April 5, 209. AX049234SCO 7-

The sample(s) are tested for the parameters as indicated in the enclosed chain of custody in accordance with the applicable laboratory certifications. This is an amended report. Please disregard all previous documentation that corresponds to the page(s) enclosed. Thank you for the opportunity to service the needs of your company. Please feel free to call me at (702) if I can be of further assistance to your company. Sincerely, Quennie Manimtim Laboratory Director The cover letter is an integral part of this analytical report.

128 ASSET Laboratories Date: 5-Nov-8 CLIENT: Project: Lab Order: CH2MHill SFPP Norwalk N03275 CASE NARRATIVE SAMPLE RECEIVING/GENERAL COMMENTS: All sample containers were received intact with proper chain of custody documentation. Information on sample receipt conditions including discrepancies can be found in attached Sample Receipt Checklist Form. Cooler temperature and sample preservation were verified upon receipt of samples if applicable. Sample was analyzed within method holding time. Results were J-Flag. "J" is used to flag those results that are between the PQL (Practical Quantitation Limit) and the calculated MDL (Method Detection Limit). Results that are "J" Flagged are estimated values since it becomes difficult to accurately quantitate the analyte near the MDL. Subcontracted Analyses: EPA 805B for DRO, ORO and GRO was subcontracted to BC Laboratories, Bakersfield, CA. Total TPH was calculated and reported in the lab based on Subcon Lab's result. Analytical Comment For EPA 8260B: RPD for Laboratory Control Sample Duplicate (LCSD) is outside criteria for 2-Butanone and Acetone; however, analyte recovery met acceptance criteria. Laboratory Control Sample (LCS) recovery biased high for Acetone. Sample results were non-detect (ND) for this analyte therefore reanalysis of the samples was not necessary.

152 ASSET Laboratories Date: 2-Nov-8 CLIENT: Project: Lab Order: CH2MHill SFPP Norwalk N CASE NARRATIVE SAMPLE RECEIVING/GENERAL COMMENTS: All sample containers were received intact with proper chain of custody documentation. Information on sample receipt conditions including discrepancies can be found in attached Sample Receipt Checklist Form. Cooler temperature and sample preservation were verified upon receipt of samples if applicable. Sample was analyzed within method holding time. Results were J-Flag. "J" is used to flag those results that are between the PQL (Practical Quantitation Limit) and the calculated MDL (Method Detection Limit). Results that are "J" Flagged are estimated values since it becomes difficult to accurately quantitate the analyte near the MDL. Subcontracted Analyses: EPA 805B for DRO, ORO and GRO was subcontracted to BC Laboratories, Bakersfield, CA. Total TPH was calculated and reported in the lab based on Subcon Lab's result. Analytical Comment for EPA 8260B: RPD for Laboratory Control Sample (LCS)/Laboratory Control Sample Duplicate (LCSD) is outside criteria for Acetone, Tert-butanol and 2-Butanone. Analytes recoveries on both met acceptance criteria. CALIFORNIA P: F: Artesia Blvd., Ste B, Cerritos, CA ELAP Cert 292 Serving Clients with Passion and Professionalism EPA ID CA0638 NEVADA P: F: W.

191 ASSET Laboratories Date: 02-Jan-9 CLIENT: Project: Lab Order: CH2MHill SFPP Norwalk N CASE NARRATIVE SAMPLE RECEIVING/GENERAL COMMENTS: All sample containers were received intact with proper chain of custody documentation. Information on sample receipt conditions including discrepancies can be found in attached Sample Receipt Checklist Form. Cooler temperature and sample preservation were verified upon receipt of samples if applicable. Sample was analyzed within method holding time. Results were J-Flag. "J" is used to flag those results that are between the PQL (Practical Quantitation Limit) and the calculated MDL (Method Detection Limit). Results that are "J" Flagged are estimated values since it becomes difficult to accurately quantitate the analyte near the MDL. Subcontracted Analyses: EPA 805B for DRO, ORO and GRO was subcontracted to BC Laboratories, Bakersfield, CA. Total TPH was calculated and reported in the lab based on Subcon Lab's result.
