Dispenser and Product Line Soil Sampling Results Report Panella Trucking, Inc., 5000 E. Fremont St., Stockton, California Page 2 Laboratory results showed sample EX -1- 10 to be below laboratory lower detection limits of 1 mg/Kg motor oil (Tables 1). Additionally, two 4:1 composite soil sample (SP -1 — SP -4 COMP) and (EX -(A -B) — (C -D) COMP)) were collected from the soil stockpile generated during the upgrade activities to profile the excavated soils for disposal purposes. Analytical Methods The soil samples were collected in accordance with Apex Standard Operating Procedures (Appendix A) and transported under chain -of -custody (COC) documentation to California Laboratory Services of Rancho Cordova, California, a State -certified analytical laboratory, and analyzed for the constituents listed below: Analysis Abbreviation Designation USEPA Method No. Extractable Petroleum Motor Oil Range TPHmo 8015M Hydrocarbons Motor Oil Hydrocarbons Total Petroleum Diesel Range TPHd 8015M Hydrocarbons as Diesel Hydrocarbons Benzene BTEX Aromatic Volatile 8260B Toluene Eth (benzene Organics Xylenes Total CAM 5 Metals 6000/7000 Series The two stockpiles analytical results were utilized by Panella for soil disposal profiling. The one stockpile associated with sample SP -1 -SP -4 Comp was disposed of at Forward Landfill in Manteca (Forward). The second stockpile associated with sample EX -(A -B) — (C -D) was analyzed for Fish Toxicity at the request from Forward Landfill (96 -hour survival Fathead Minnows). This test showed the soils to be Non -Hazardous (Table 2). This stockpile was then disposed of at Forward. The laboratory analytical reports and chain -of -custody forms are included as Appendix B. SUMMARY OF FINDINGS Based on soil laboratory analytical results, the maximum concentration of TPHmo and TPHd was detected at 12,000 milligrams per kilogram (mg/kg), and 110 mg/kg, respectively. The TPHmo maximum concentration soil samples D-24', PL -104' and EX -1-7'. The TPHd maximum concentration soil sample PL -1-4'. TPHmo and TPHd concentrations were reported in stockpile sample SP -1 -SP -4 COMP at 170 and 150 mg/kg, respectively. TPHmo concentrations were reported in stockpile sample EX -(A- B) -(C -D) COMP at 16,000 mg/Kg. The remaining constituents in both stockpile samples were reported below laboratory detection limits. Analytical results are summarized on Tables 1, 2 and 3. Panella Trucking is currently processing disposal with Forward Inc Landfill, Manteca, CA
