The third tank was removed at 2:30 p. m. It was 2,000-gallons in capacity. This tank was moderately rusted, and was somewhat softer and less solid than tanks 1 and 2. In addition, the soil beneath the tank in the excavation was slightly cemented by iron oxide (rust). However, no holes were observed in the tank. 4.0 COLLECTION AND ANALYSIS OF SOIL SAMPLES After all tanks were removed, an excavator from Bob Evans Trucking was used to remove approximately two feet of soil from beneath the tanks. Upgradient then collected eight samples from the excavator bucket, using a percussion slide hammer loaded with 2 x 3-inch brass sample sleeves. Two samples were collected from beneath tank 3, and three samples were collected from beneath tanks 1 and 2. In addition, six samples were collected from the product line trenches. These samples were spaced at 20-foot intervals, and were collected from the base of the sidewalls after all sloughed soil had been cleared away. Mr. Jerry Yoshioka of PHS/EHD witnessed the sampling. After Mr. Yoshioka left the site, five additional samples were collected from the soil stockpiles. The approximate locations of all samples are shown in Figure 2. The samples were immediately sealed with Teflon sheets, capped, and placed in a cooled ice chest. When all samples had been collected, they were transported under chain-of-custody to Excelchem Environmental Laboratories in Roseville for analysis. Hydrocarbon odors were evident in only one of the 19 samples (JL-P-3). This sample was taken from beneath the south end of the western dispenser island (Figure 2), from gray, discolored soil that was obviously contaminated with gasoline. Therefore, the four samples from the dispenser trenches were analyzed on 24-hour turnaround to expedite any soil remediation that might be necessary. Upgradient also requested the laboratory to composite the five stockpile samples into a single sample for analysis and to run this sample on expedited turnaround as well. Excelchem analyzed the samples for Total Petroleum Hydrocarbons in the gasoline range(TPH-g) and the volatile aromatic hydrocarbons benzene, toluene, ethylbenzene, and xylene (BTEX). The stockpile composite was also analyzed for reactivity, corrosivity, and ignitability (RCI) and for the five priority metals (Cr, Cd, Pb, Ni, and Zn) in the event that gasoline was detected and it became necessary to transport the stockpile to a disposal facility. The laboratory report is included as Attachment A. 5.0 EXCAVATION BACKFILL Immediately after the soil samples were collected, Bob Evans Trucking began backfilling the tank excavation with the stockpiled soil. This was done in order to allow truck access to the diesel fueling facility, which had been significantly impacted by the restricted access caused by the tank removal 2
