beneath the former fuel dispenser location. In addition, four soil samples (SP-1, SP-2, SP-1- <br /> D, and SP-2-D) were taken from the excavation overburden spoils pile, to facilitate soil <br /> disposal (Figure 4). <br /> The soil samples from the tank excavation side walls were collected from native soil in the <br /> backhoe bucket, utilizing two-inch by six-inch brass sleeves. The dispenser and stockpile <br /> samples were collected using a sample coring device, containing two inch by six inch brass <br /> sleeves. The sample corer was driven into each desired sampling location using an attached <br /> slide hammer. The backhoe was not used to obtain the dispenser or stockpile samples. Soil <br /> sampling locations are shown on Figures 3 and 4. <br /> After collection and labeling, the samples were immediately put on ice and cooled to <br /> approximately 4°C. Chain of Custody documentation accompanied all samples from the time <br /> of collection to the time of delivery to the onsite Sparger Technology Incorporated laboratory. <br /> Copies of the Analysis Request and Chain of Custody records for these samples are included <br /> ' in this UST removal report as Appendix D. <br /> 2.3 Sample Analysis <br /> The methods utilized in the analysis of the soil samples were modified EPA Method 8015 <br /> with a gasoline standard and Method 8020 used for BTEX distinction. The duplicate <br /> composite stockpile soil samples (SP-1-D and SP-2-D) were additionally analyzed for total <br /> lead and reactivity, corrosivity, and ignitability (RCI) to facilitate disposal, using EPA method <br /> 7420 and California Title 22 Section 66261.21 - 66261.23 methodology respectively. <br /> A state-certified mobile laboratory operated by Sparger Technology Incorporated, was utilized <br /> onsite for the gasoline and BTEX analysis of the original soil samples (5) collected during <br /> ' tank excavation. Duplicate composite stockpile soil samples (SP-1-D and SP-2-D) were <br /> collected for the purpose of additional analysis, which the mobile lab was not able to perform. <br /> ' The duplicate soil samples were analyzed (for total lead and RCI) by McCampbell Analytical <br /> Incorporated in Pacheco, California. <br /> ' Analysis of soil samples collected from the unleaded gasoline tank excavation side walls (TP- <br /> A and TP-2) and beneath the dispenser island ('Dispenser") revealed no detectable <br /> concentrations of petroleum hydrocarbons. <br /> MZ104-11-95/UST/95.0102.NBR 3 <br />
