No AGE or subcontractor <br /> personnel will be allowed into any excavation greater than five bsg without proper excavation <br /> shoring and/or sloping techniques in-practice. <br /> 4.2. 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. The <br /> exposed ends of the sample sleeve will be covered with Teflon 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 by hand sampling methods using a stainless steel or carbon <br /> steel trowel, or by pressing a brass sampling sleeve into the soil stockpile. <br /> Following sample collection, each sample sleeve will be labeled with the boring location, depth, <br /> time,date and sampler's initials.Appropriately sealed and labeled samples will be placed in a chilled <br /> container under ice and transported under chain-of-custody procedure to a DHS-certified laboratory. <br /> 4.3. EQUIPMENT DECONTAMINATION <br /> Prior to each sample collection, all sampling tools used for sample collection will be thoroughly <br /> rinsed with clean water after being washed with a solution of Alconox and water. <br /> Advanced GeoEnviron mental <br />
