IlLionudakis Firewood, Inc. Page 5 of 9 Samples collected for Baker Tank 2 analysis were analyzed for the following: • TEPHk and TEPHmo by EPA method 8015M • VOCs by EPA method 8260B • Semi-Volatile Organics (Full Scan)by EPA method 8070C • Dissolved Metals by EPA method 200.8 2.2 Storm Drain Test Analytical Results All analyzed petroleum hydrocarbon constituents, volatile organic compounds, and semi-volatile organic compounds from both sampling events were not reportable above laboratory detection limits. Dissolved metals were below Maximum Contaminant Levels (MCLs), Action Levels, or Notification Levels established by California Department of Public Health and the Department of Health Services. Figure 3 presents a map of the storm drain system and indicates the sample locations. Analytical results from the Storm Drain Test are summarized in Table 3. Analytical results from the Baker Tank 2 are summarized in Table 4 and Table 5. Field Notes are included as Attachment B-1 and Laboratory Analytical Reports are included as Attachment C-1 and C-2. 3.0 SOIL BORING INVESTIGATION 3.1 Permitting and Pre-Field Work Activities A soil boring permit (SR# 0058733) was obtained from EHD prior to drilling activities. A copy of the permit is included as Attachment D-1. Mr. David Irey and EHD were notified at least 72 hours prior to conducting drilling activities. 3.2 Soil Boring Investigation On November 24, 2009, an experienced Ground Zero geologist under supervision of a professional geologist was on-site to oversee the advancement of seven (7) soil borings using GeoProbe® drilling equipment owned and operated by V&W Drilling (C57# 720904). A grid pattern of six sampling locations was determined prior to drilling (GPI-GP6). EHD reviewed field data and request one additional boring location (GP7). The borings were grouted to surface with neat cement. Drill cuttings produced were placed in a properly labeled DOT approved 55-gallon drum, temporarily stored on-site, and disposed of with excavated material. Based on the Geoprobe® investigation an estimate of the volume of soil requiring disposal was prepared for landfill disposal purposes. Soil samples were collected continuously in each of the borings from the surface to a depth of 20 feet bgs. Soil samples were collected in clear commercial liners for lithologic identification, subjective analysis with a PID, and selected laboratory analysis. Based on field observations and PID measurements, five selected soil samples were submitted for laboratory analysis to confirm the diesel contamination detected during the EHD investigation and to profile the soil for disposal. Sections of the liners were cut to length, sealed with Teflon®tape, capped, uniquely labeled, and G:IGROUNDZEILIONUDAKISIReportslSite Assessment and Excavation Report.doc March 2010
