Interim Soil Remediation Work Plan <br /> Former TRACY DINER <br /> 95 West Eleventh Street, Tracy, California <br /> 1.0. INTRODUCTION <br /> At the request of Mr Joe Panetta, Advanced GeoEnvironmental, Inc (AGE) has prepared this <br /> Interim Soil Remediation Work Plan for the former Tracy Diner, 95 West 10 Street, Tracy, <br /> California California The scope of work includes overexcavation and sampling of contaminated <br /> soil encountered at the site as a result of the discovery of an Underground Storage Tank(UST) The <br /> objective of the work is to remove potential contaminant sources to the ground water On the 21 <br /> October 2003 AGE discovered a previously unknown UST at the site south of the existing MW-2 <br /> Visible hydrocarbon staining was observed in the surrounding soil <br /> This work plan has been prepared in accordance with the Regional Water Quality Control Board's <br /> Tri-Regional Board Staff Recommendations for Preliminary Evaluation and Investigation of <br /> Underground Tank Sates guidelines for the investigation of UST sites <br /> 2.0. BACKGROUND <br /> . The site is located at 95 West 11`h Street,Tracy,California,in an arca of commercial and residential <br /> use The site is situated at the intersection of West Eleventh Street and Adams Street, in an area of <br /> low topographic relief, at an elevation of approximately 18 feet above mean sea level (Figure 1), <br /> Tracy Quadrangle,7 5-Minute USGS Topographic Series, 1968,photo revised 1976 The prominent <br /> features on the subject property are depicted in Figure 2 <br /> 21 REGIONAL GEOLOGIC/HYDROGEOLOGIC SETTING <br /> The site is located within the northern San Joaquin Valley which comprises part of the Great Valley <br /> geomorphic province of California The San Joaquin Valley is formed by the Great Valley <br /> geosynclme, which is a large, elongate, northwest-trending asymmetrical structural trough (basin) <br /> It is bordered by the Coast Ranges to the west, the Klamath Mountains and Cascade Range to the <br /> north, and the Sierra Nevada to the east This trough has been filled with sediments derived from <br /> both marine and continental sources The thickness of the sedimentary fill ranges from thin veneers <br /> along the valley edges to greater than 20,000 feet in the south central portion of the valley The <br /> sedimentary formations range in age with the older deposits being primarily marine in origin and the <br /> younger deposits being primarily continental Continental-derived sediments were pninanly <br /> deposited in lacustrine, fluvial, and alluvial environments with sources being the mountain ranges <br /> surrounding the valley(Olmsted and Davis, 196 1) The site is located on unconsolidated and semi- <br /> consolidated alluvium, lake, playa and terrace deposits of Quaternary age (California Division of <br /> Mines and Geology, 1977) <br /> Advanced GeoEnvuronmental,Inc <br />
