G <br />r <br />f. <br />u <br />u <br />n <br />it <br />r <br />The tank was triple rinsed by IT Corporation representatives on January 18, 1995. The <br />rinsate was removed using a vacuum truck provided by Ramos Environmental Services. The <br />total volume of rinsate water removed was 160 gallons. The rinsate was transported by <br />Ramos Environmental under manifest control (No. 92325735) to their facility in Sacramento, <br />California, for recycling (Appendix A). <br />Tank removal activities resumed on January 19, 1995. Immediately prior to removal, the tank <br />was inerted with approximately 40 pounds of dry ice. Atmospheric readings were measured <br />inside the tank under the direction of Inspector Robert McClellon of the San Joaquin County <br />Environmental Health Division. Permission to remove the tank was granted. <br />Upon removal, the tank appeared sound; no petroleum hydrocarbon odors or stained soils <br />were encountered. No staining was encountered beneath the piping and no groundwater <br />infiltrated the excavation or the piping trench. <br />The removed tank was loaded onto a flat-bed truck and transported by Erickson, Inc., to their <br />facility in Richmond, California, for cleaning and recycling. The tank was transported under <br />manifest control (95206026) to the Erickson facility in Richmond for recycling. Documents <br />pertaining to the transport and disposal of the tank are included as Appendix B. <br />2.2 Soil Sampling <br />Under the direction of Inspector Robert McClellon on January 19, 1995, five soil samples <br />were collected from the excavation base after removal of the excavation fill material. Two <br />soil samples were collected from beneath the tanks piping upon its removal. In addition, two <br />four point composite soil samples were taken from the excavation overburden spoils pile <br />(Figure 3). <br />The soil samples from the tank excavation floor were collected from native soil in the <br />backhoe bucket utilizing two-inch by six-inch brass sleeves. The piping and stockpile <br />samples were collected directly, using a soil coring device and attached slide hammer. Soil <br />sampling locations are shown on Figure 3. After collection and labeling, the samples were <br />immediately put on ice and cooled to approximately 4°C. Chain of Custody documentation <br />accompanied all samples from the time of collection to the time of delivery to the on-site <br />MZ/02-17-96/UST/95-0033.nbr 2 <br />
