2.0 Project Activities and Site Background <br /> 2.1 Site Description <br /> The Company's Stockton Service Center is located at 4040 West Lane in Stockton, California <br /> w <br /> (Figure 1). The soil remediation activities addressed by this HASP will be performed at the <br /> i , <br /> gasoline and diesel refueling facility located on the north side of the vehicle maintenance garage. <br /> 2.2 Description of Hazardous Substances On-site <br /> Soil samples have been collected at the site. Total petroleum hydrocarbons as gasoline (TPH-g) <br /> were detected at concentrations ranging from 1.4 milligrams per kilogram (mg/kg)to 450 mg/kg. <br /> Total petroleum hydrocarbons as diesel (TPH-d) were detected at concentrations ranging from <br /> 67 mg/kg to 7,000 mg/kg. Benzene was not detected. Toluene was detected in one sample at a <br /> concentration of 0.017 mg/kg. Ethylbenzene was detected at concentrations ranging from <br /> 0.031 mg/kg to 0.041 mg/kg. Xylenes were detected at concentrations ranging from 0.16 mg/kg <br /> to 0.18 mg/kg. Methyl tertiary butyl-ether(MTBE)was not detected. Lead concentrations <br /> ranged from 5.6 mg/kg to 27 mg/kg. <br /> 2.3 Project Scope <br /> The scope of the project will consist of reconnaissance soil sampling to determine the extent of <br /> TPH contamination, excavation and disposal of contaminated soils and confirmation sampling. <br /> I <br /> r! <br /> i <br /> I <br /> a <br /> i <br /> i <br /> I <br /> I <br /> M <br /> 1 <br /> sucDP-N:IConsrrleingidaraLSharedlProjectsiPJ7l78d07,aadoc1 <br /> !2/7100 2-1 <br />
