SOIL EXCAVATION PROCEDURES <br /> Soil will be excavated using a backhoe or excavator. Soil will be leaded into end dump loaders for <br /> disposal at Forward Landfill or temporarily stored on plastic for loading and disposal. Excavated soil <br /> will be field screened for the presence of VOCs using an OVM. Based on OVM readings and field <br /> observations, excavated soil will be segregated into stockpiles of clean soil (if appropriate) and <br /> impacted soil. <br /> The vertical limit of the excavation will be a maximum of 8 feet bsg. The lateral limits of the <br /> excavation will be determined by field observations. The maximum lateral dimensions of either side <br /> of the excavation will not exceed 25 feet in either direction, unless the vertical extent of the <br /> contamination has been determined and the lateral extent is more extensive than vertical extent. <br /> The open excavation area will be backfilled with clean fill and crushed rock or pea gravel. No AGE <br /> or subcontractor personnel will be allowed into any excavation greater than five bsg without proper <br /> excavation shoring and/or sloping techniques in-practice. <br /> 4.1.1. Soil Sampling Procedures <br /> Soil samples collected from the base and sidewalls of the excavation will be obtained using a <br /> backhoe or excavator. Soil samples will be collected from the bucket of the excavating equipment <br /> by pressing a 3-inch long by 2-inch diameter brass sleeve into the excavated soil material using a <br /> metric soil sampling hammer. The exposed ends of the sample sleeve will be covered with Teflon <br /> sheets, capped and sealed with tape. <br /> Soil samples will be collected from soil stockpiles by digging approximately one foot into the soil <br /> stockpile. Soil samples will be collected pressing a brass sampling sleeve into the soil stockpile with <br /> a metric soil sampler. <br /> Following collection and preservation, each sample sleeve will be labeled with the boring location, <br /> depth, time, date and sampler's initials. Appropriately sealed and labeled samples will be placed in <br /> a chilled container under ice and transported under chain-of-custody procedure to a DHS-certified <br /> laboratory. <br /> Advanced CeoEnvironmental,Inc. <br />
