SECTION B <br /> SAMPLING AND ANALYSIS PLAN <br /> B1.0 SITE BACKGROUND <br /> Tracy Auxiliary Field No. 5 is located in the City of Tracy, San Joaquin County, <br /> California. The Field was operating as an auxiliary landing field during the period <br /> form 1942 to 1947. It is currently operated as Tracy Municipal Airport, but there <br /> was not much on-going activity at the airport during the site visit in mid-March, <br /> 1995. <br /> Site environmental setting data are not available at the Corps of Engineers Office <br /> for review. The COR and technical manager have been contacted for this <br /> information. <br /> Major tasks in this Delivery Order include: <br /> • Removal and disposal of one 10,000-gallon underground storage tank. <br /> • Disposal of contaminated soil, if any. <br /> • Removal and disposal of 100 linear feet of fuel lines. <br /> B2.0 DATA QUALITY OBJECTIVES <br /> The chemical data obtained at the Tracy Municipal Airport is intended to provide the <br /> concentrations of total petroleum hydrocarbons (TPH)-diesel, TPH-gasoline, <br /> aromatic hydrocarbons, and lead in soil and water if groundwater is encountered <br /> during excavation. The chemical data will be used to document the levels of <br /> petroleum contamination remaining in soil after the excavation of the UST and fuel <br /> lines. <br /> Other important measures of project data quality such as precision, accuracy, <br /> representativeness, completeness, and comparability are described in the CDQMP <br /> of the GMP. <br /> B3.0 SAMPLING OBJECTIVES <br /> • To obtain representative samples for laboratory analysis for TPH-diesel, <br /> TPH-gasoline, aromatic hydrocarbons, and lead. <br /> • To obtain defensible data for the proper, legal disposal. <br /> • <br /> B-1 <br />
