0 <br />sampling, thus avoiding loss of volatile constituents. All soil samples will be placed in the <br />appropriate sample container, taped, labeled, placed in a resealable plastic bag, and stored in a <br />cooler containing ice. <br />2.4.5 Open Pit Water Sampling <br />Water samples will be taken from within the excavation pit if the ground -water level is <br />higher than the bottom of the excavation. To collect a water sample from the tank excavation <br />pit, a teflon bailer will be submerged allowing water to slowly fill the bailer. If the sampling <br />point is beyond the collector's reach, a rope will be used to lower the bailer into the pit. In either <br />case, the bailer will be submerged and removed to minimize surface disturbance. The real and <br />duplicate sample for each analyte will be taken from the same bailer of ground water. <br />2.4.6 Site Closure and Finishing <br />After completing the soil excavation and sampling, the excavation pit will be backfilled <br />with clean soil or gravel and compacted in one foot lifts. The site will then be covered with an <br />asphalt patch to be compatible with the surrounding pavement. <br />2.4.7 Handling Contaminated Materials <br />The tank removal activity may generate a variety of contaminated materials. The <br />following describes methods of handling various types of contaminated materials that may be <br />generated. All contaminated materials will be handled under proper manifests and by licensed <br />transport and disposal facilities. <br />Contaminated Soils <br />All contaminated soils will be stockpiled on plastic sheeting next to the excavation. These <br />soil piles will be covered with plastic sheeting until they are transported off-site. Contaminated <br />soil will be disposed of at a Class I or II landfill, depending on the contaminated soils <br />characteristics determined from soil pile sample analyses. <br />Tank Rinsates <br />Tank rinsate materials, generated during cleaning of the tank, will be handled as <br />hazardous waste and will be disposed of at an appropriate facility. These materials will be <br />collected with a vacuum truck for transport to the disposal facility. <br />14 <br />
