Job No. 4780200 . - Page 3 ' analysis. One additional boring will be drilled at the location of the former dispenser. This boring will be 4-feet deep and one soil sample will be collected from the bottom (4 feet). These samples will be analyzed for Total Petroleum Hydrocarbons as gasoline (TPHg), Benzene, ' Toluene, Ethyl benzene, and Xylenes (BTEX). ' • Drill one soil boring at the former location of the 1 ,000-gallon diesel UST. This boring will be drilled to a depth of approximately 20 feet. ' Soil samples will be collected at 5-foot intervals for subsequent analysis. A soil sample will be collected from the former dispenser location. All ' samples will be analyzed for TPH as diesel (TPHd) and BTEX. • Drill one soil boring at the former location of the 8,000-gallon, leaded gasoline UST. This boring will be drilled to a depth of approximately 20 feet. Soil samples will be collected at 5-foot intervals for subsequent ' analysis. A 10-foot deep boring will also be advanced at the former location of the dispenser serving this UST. Two soil samples will be ' collected from this boring at depths of approximately 5 and 10 feet. A third soil boring will be drilled to an approximate depth of 4 feet in the area where it is believed that two former fuel dispensers serving this UST were located. A sample will be collected from a depth of 4 feet in ' this boring. All samples will be analyzed for TPHg, BTEX, Total Lead, and Volatile Organic Compounds (VOCs). VOC analysis will be ' conducted using EPA test method 8240. ' • Two discrete soil samples will be collected from the existing stockpile of soil. These two samples will be composited at the laboratory and ' analyzed for TPHg, TPHd and BTEX, Total Lead, and VOCs. ' • Soil generated during drilling will be stockpiled with the existing stockpile of soil. The open boreholes will then be backfilled with a neat cement ' grout as required by the SJCPHS. ' EC, Inc.
