SOIL DISPOSAL <br /> After soil disposal characterization,the hydrocarbon-impacted excavated soil will be transported to <br /> the appropriate, licensed landfill for disposal. <br /> 4.0. FIELD PROCEDURES <br /> All field procedures will be overseen by an AGE representative under the supervision of a California <br /> Registered Geologist.Procedures for soil excavation,soil sampling and equipment decontamination <br /> are outlined below. <br /> 4.1. SOIL EXCAVATION PROCEDURES <br /> The soil will be excavated using an excavator and stockpiled on-site, covered by a plastic tarp. The <br /> excavated soil will be field screened for the presence of volatile organic compounds using an OVM. <br /> Based on OVM readings and field observations,the excavated soil will be segregated into clean soil <br /> and impacted soil; only soil exhibiting hydrocarbon odors or measured OVM readings will be <br /> disposed to a licenced landfill. <br /> Prior to disposal,the hydrocarbon-impacted soil will be characterized by aDHS-certified laboratory. <br /> After soil characterization,trucks will be utilized to transport the waste material for proper disposal. <br /> The open excavation area will be surrounded by temporary fencing. No AGE or subcontractor <br /> personnel will be allowed into any excavation greater than five feet bsg until proper excavation <br /> shoring and/or sloping techniques have been emplaced. <br /> 4.2. SOIL SAMPLING PROCEDURES <br /> Soil samples collected from the base and sidewalls of the excavation will be obtained using the <br /> excavator. Soil samples will be collected from the bucket of the excavating equipment with a metric <br /> soil sampling hammer and one 6-inch long by 2-inch diameter brass sleeve,from the excavated soil <br /> Advanced GwEnvironmental,Inc. <br />
