3. <br /> oStep - Remove man-way cover or fill neck and confirm that product <br /> has been removed. If for some reason the product has not been <br /> removed, contact SPTCo. for removal . The tank should then be <br /> inerted to remove all vapors using dry ice as described in Section <br /> 2.4. <br /> o Stop - Continue excavation operations until the tank is free and <br /> clear for removal . As mentioned above, contaminated soils ( if <br /> present) and clean soils will be segregated. If contaminated <br /> ' soils are present, they will be either drummed or stockpiled on <br /> bermed visquene for off-site disposal . The decision to drum or <br /> stockpile soils will be based on soil volume and site access. <br /> ' o Sttep4 - Use cable rigging fastened to the tank to lift the tank <br /> from the excavation. A backhoe will be used to remove the tank from <br /> ' the excavation. <br /> o Stg5 - After the tank have been removed from the excavations, the <br /> soils underlying the tank will be inspected for the presence of <br /> product. The field engineer will then make a decision regarding the <br /> need for additional excavation. When contamination is evident, <br /> additional excavation will be performed until clean soil is <br /> ' encountered or until further excavation is no longer feasible. As <br /> mentioned above, any contaminated soil , encountered will be placed <br /> in drums or stockpiled on visquene. Samples will be analyzed within <br /> 48 hours for the constituents described in Section 2.3. The need <br /> for additional excavation operations will be dependent upon the <br /> results of the chemical analyses. <br /> o Sten 6 - The excavated tank(s) will be manifested and transported as <br /> hazardous waste in compliance with the C.A.C. Title 23, Subchapter <br /> 16 Underground Tank Regulations. This will be accomplished by H 8 H <br /> Ship Service located in San Francisco, California. <br /> o Ste{ 7 - After excavation and sampling Operations have been <br /> completed, the pit will be backfilled and the site restored to its <br /> original condition. Closure and restoration will be in accordance <br /> with the procedures outlined in Section 2.5. <br /> 2.3 Soil Sample Collection and Analyses <br /> Subsequent to tank removal and excavation operations, a soil sample will be <br /> obtained below each tank at least one foot below the backfill material and <br /> ' approximately one third of the way in from the end of each tank. The soil <br /> will be obtained from the bottom of the pit with the backhoe. The soil <br /> ' samples will be collected using two-inch by four-inch brass sample tubes <br /> CanonieE nv i ronmenta l <br />
