FIELD PROCEDURES <br /> All field procedures will be overseen by an AGE representative under the supervision of <br /> a California Professional Geologist. Procedures for soil excavation, soil sampling, and <br /> equipment decontamination are outlined below. <br /> 3.1 . SOIL EXCAVATION PROCEDURES <br /> Soil will be excavated using a deep reach excavator. Following excavation, soil will be <br /> placed into end-dump trucks for transportation to Forward Landfill. Excavated soil will <br /> be field screened for the presence of volatile organic compounds using an OVM. Based <br /> on OVM readings and field observations, excavated soil will be segregated into clean <br /> soil (if appropriate) and impacted soil; only soil exhibiting hydrocarbon odors or <br /> measured OVM readings will be transported for disposal. <br /> The open excavation area will be surrounded by temporary fencing. No AGE or <br /> subcontractor personnel will be allowed into any excavation greater than five feet bsg <br /> without proper excavation shoring and/or sloping techniques in-practice. <br /> 3.2. SOIL SAMPLING PROCEDURES <br /> Soil samples collected from the base and sidewalls of the excavation will be obtained <br /> using a backhoe or excavator. Soil samples will be collected from the bucket of the <br /> excavating equipment with a metric soil sampling slide-hammer and one 6-inch long by <br /> 2-inch diameter steel sleeve, from the excavated soil material. The exposed ends of the <br /> 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 <br /> the soil stockpile. Soil samples will be collected by hand sampling methods using a <br /> stainless steel or carbon steel trowel, or by pressing a steel sampling sleeve into the <br /> soil stockpile. <br /> Following sample collection, each sample sleeve will be labeled with the boring location, <br /> depth, time, date and sampler's initials. Appropriately sealed and labeled samples will <br /> be placed in a chilled container under ice and transported under chain-of-custody <br /> procedure to a CDPH-certified laboratory. <br /> 3.3. EQUIPMENT DECONTAMINATION <br /> Prior to each sample collection, all sampling tools used for sample collection will be <br /> thoroughly rinsed with clean water after being washed with a solution of Alconox. <br /> Advanced GeoEnvironmental Inc. <br />
