r <br /> contamination was apparent in the fuel pipe trenches. Confirmatory in-situ . <br /> soil samples were collected from UST excavations on February 8, and from the <br /> fuel and oil pipe trenches on February 21 (Table 1). Removal of USTs and <br /> w confirmatory sampling was performed in the presence of and with the <br /> concurrence of San Joaquin County Public Health Services Department and City <br /> of Stockton Fire Department personnel. Soil sampling is discussed in Section <br /> 3.2 and analytical results are discussed in Section 5.0. <br /> Mr _ <br /> i Excavated soils were placed in stockpiles and segregated as originating from <br /> 9<, <br /> either the "new" excavation, the fuel UST excavation, or the motor aind used <br /> oil UST excavation. Composite soil' samples were taken from stockpiles in <br /> order to determine appropriate disposal methods. Soil, sampling is discussed <br /> in Section 3.2 and analytical results and disposal are discussed in Section <br /> i , 5.0. <br /> 2.0 SCOPE OF WORK <br /> -yF✓ <br /> IT'S work pertained to environmental aspects of UST removal and replacement, <br /> r4! and characterization and disposal of stockpiled soils from the UST excays- <br /> tions. Specifically, IT'S scope of work included: <br /> Preparing a Site Safety Plan for UST removal <br /> • Coordinating destruction of monitoring well MW-2 <br /> • Observing UST removal <br /> • Coordinating sampling and inalysis of in-situ soil samples from UST, <br /> piping and other excavations <br /> • Coordinating interim remediation activities, as necessary, to allow <br /> station reconstruction to continue <br /> Coordinating sampling, analysis and disposal of stockpiled soils <br /> Preparing a Tank Closure Report. <br /> 1 , <br /> 2 . <br /> �,A:ENG:9199/041591 <br />
