Project No. 076-97005 <br /> Page No.3 <br /> collected from beneath the northern and southern ends of each gasoline UST. Refer to Figure No. 2 for <br /> soil sample locations. <br /> Subsequent to the removal of the USTs, the product pipelines associated with the fuel oil USTs <br /> were excavated and removed. The product pipelines appeared rusted. As directed by Mr. Trevena, <br /> Krazan's representative collected three soil samples (P-1 through P-3) from beneath the product <br /> pipelines on April 10, 1998. Soil samples were collected from a depth of 1.5 to 2.0 feet below the <br /> product lines. Refer to Figure No. 2 for soil sample locations. Krazan representatives also collected <br /> r <br /> three soil samples from the stockpiled soil removed from the excavation(SP-1 through SP-3), as directed <br /> by Mr. Trevena. <br /> Following sample collection, the ends of each sample sleeve were covered by Teflon film and <br /> sealed with tight fitting plastic caps secured by inert tape. The sample sleeves were labeled and placed in <br /> a cooler chest, which contained synthetic ice cooled to approximately 4 degrees Celsius (4°C). Samples <br /> were then transported under Chain-of-Custody protocol to a State-certified analytical laboratory for <br /> ` analysis. As directed by Mr. Trevena, the soil samples collected from beneath the USTs, product <br /> pipelines, and the stockpile were submitted for analysis of benzene, toluene, ethylbenzene, and xylenes <br /> (BTEX) by EPA Method 8020, and total petroleum hydrocarbons as diesel (TPH-D) by EPA Method <br /> 8015M. The results of the chemical analyses associated with the petroleum hydrocarbon constituents <br /> ` (PHCs) are summarized in Table II.
