1 September 9, 2015 Attn: Mr. Paul Cho California Regional Water Quality Control Board Los Angeles Region 320 West 4 th Street, Suite 200 Los Angeles, California RE: Mr. Cho: Report of August, 2015, Pipeline Release Defense Fuel Support Point Norwalk Norwalk Boulevard, Norwalk, California Contract No. SPO D-54 Project No. 04-LA-007 This report was prepared by (SGI), to document a pipeline release that occurred on August, 2015, at the Defense Fuel Support Point (DFSP) Norwalk in Norwalk, California (Figure 1). Pipeline Release and Response The release occurred while uncovering an 8-inch-diameter buried pipeline in the western portion of the Powerine Basin in the north-central area of the site (Figure 2) at approximately 8:15 AM on August, The pipeline excavation was approximately 80 feet long, nine feet wide, and between two and three feet deep. The release was discovered when the excavator operator observed a neon green colored liquid leaking from the pipeline. The site geologist noted a sweet odor from the released liquid; hydrocarbon odors were not observed. The area was immediately secured and a vacuum truck provided and operated by Nieto and Sons Trucking from Brea, California, was mobilized to the site. The vacuum truck arrived on site at approximately 9:30 AM and began recovering the released liquid. The released fluid was recovered from the excavation and the vacuum truck also recovered as much as possible from the broken pipeline. Approximately 160 gallons were recovered. Soil exposed to the liquid was excavated and placed on plastic sheeting pending characterization. The damaged section of the pipeline was removed and the pipeline was capped. The Regional Water Quality Control Board (Mr. Paul Cho) was notified on August 11, 2015, by telephone. Attachment A provides a completed copy of an incident report form summarizing the release and actions taken after the pipeline was damaged. Photographs of the pipeline release and recovery operations are provided as Attachment B. Former DFSP Norwalk Terminal Manager, Mr. John Rifilato, was contacted to inquire whether he had any information regarding the released liquid. According to Mr. Rifilato, he could not provide specific details of what was used to fill the line; however, he did recall that the Powerine line was taken out of service in the early 1990 s (Mr. John Rifilato, personal communication, August 24, 2015). Sampling and Analytical s Pipeline Liquid Based on the neon-green color of the liquid, the presence of dyed ethylene glycol was suspected to be present. A sample of the liquid was collected and submitted to Advanced Technical Laboratories (ATL) in Signal Hill, California, for analysis of ethylene glycol in accordance with Telephone: (562) Facsimile: (562) Signal Hill, California nirish@thesourcegroup.net

2 Report of August, 2015, Pipeline Release September 8, 2015 Defense Fuel Support Point Norwalk, Norwalk Boulevard, Norwalk, California Page 2 Environmental Protection Agency (EPA) Method 8015B. The sample was non-detect (<200 milligrams per liter [mg/l]) for ethylene glycol. The laboratory report is provided in Attachment C. Because ethylene glycol was not detected in the liquid sample, a second sample was collected on August 17, 2015, and submitted to Ozark Underground Laboratory, Inc., in Protem, Missouri, to test for the presence of tracer dyes. Ozark Underground Laboratory is a private consulting and contract studies firm that provides groundwater tracing throughout North America. Since 1973, the Ozark Underground Laboratory has designed and either conducted, or assisted with, over 4,000 groundwater traces in the United States, Canada, Australia, Barbados, Indonesia, New Zealand, and Peru. Their experience with tracer dyes and testing make them ideally suited for this evaluation. The results of analysis indicated the presence of the tracer dye, fluorescein, at a concentration of 89.2 parts per million (ppm). The laboratory report is provided in Attachment C. Sampling and Analytical s Soil Samples Ten soil samples were collected from the excavation sidewalls (four samples: POWERINE-TRENCH-1 through POWERINE-TRENCH-4) and floor (six samples: POWERINE-TRENCH-5 through POWERINE-TRENCH-) on August 11, 2015, and submitted for analysis of total petroleum hydrocarbons (TPH; carbon chain characterization) in accordance with EPA Method 8015M, volatile organic compounds (VOCs) in accordance with EPA Method 8260B, and Title 22 metals in accordance with EPA Method 60B. Analytical results are summarized in Table 1 (TPH) and Table 2 (metals). The laboratory report is provided as Attachment D. TPH was reported in two of the ten pipeline excavation samples (Table 1). Sample POWERINE-TRENCH-3 was reported to contain 330 milligrams per kilogram and sample POWERINE-TRENCH-4 was reported to contain 120 mg/kg TPH. TPH was not detected in the remaining eight samples at or above the -mg/kg practical Quantitation Limit (). VOCs were not detected at or above the s in any of the pipeline excavation samples. Analytical results for metals in pipeline excavation soil samples are summarized in Table 2. Title 22 metals were detected at low concentrations, consistent with local background concentrations; antimony, beryllium, cadmium, molybdenum, selenium, silver, and thallium were not detected in any of the analyzed trench samples at or above s (Table 2). Waste Disposition Because the analytical results indicated that no RWQCB-approved cleanup goals were exceeded, we recommend that the excavation be filled with native soil. Drums containing the recovered liquid were picked up on September 3, 2015, by American Integrated Services, Inc., from Wilmington, California, and transported under manifest to Crosby and Overton in Long Beach, California, for disposal. A copy of the hazardous waste manifest is provided as Attachment E. Work Completed to Identify Underground Pipelines DFSP Norwalk Buried pipelines were historically used to convey fuel products to and from the ASTs and pumping stations located at DFSP Norwalk. Buried pipelines were also used to deliver water via the fire hydrant system that serviced the entire facility. Additionally, intra-facility storm drains Telephone: (562) Facsimile: (562) Signal Hill, California nirish@thesourcegroup.net

3 Report of August, 2015, Pipeline Release September 8, 2015 Defense Fuel Support Point Norwalk, Norwalk Boulevard, Norwalk, California Page 3 were used to convey rainwater from the tank basins to the oil/water separate that was formerly present in the southwest corner of the facility. During 2012, the underground petroleum pipelines, fire water lines, storm drain lines, and oil/water separator were removed. This work was documented in Parsons February 13, 2013, report entitled Concrete Demolition and Soil Confirmation Sampling Completion Report (Parsons Report). In conjunction with that project, a geophysical survey was completed to evaluate the presence and location of buried pipelines located at the facility. Based on the results of that survey (See Attachment F), the identified underground pipelines were removed. However, it appears that the Powerine basin was not included in that survey and thus the pipeline encountered during SGI s work in August 2015 had not been identified or removed. The map of buried pipelines and the Parsons Report provides substantial documentation as to the efforts made to identify and remove buried pipelines from the facility. The pipeline that was recently encountered should therefore be considered an anomaly and no additional buried pipelines are expected to be encountered. Further evidence that all underground pipelines have been removed from the site will be provided upon completion of exploratory trenches in those areas of the facility that are currently believed to be clean, and thus require no soil excavation for purposes of removing contaminated soil.
