r Mr. Steve Sasson <br /> Page 2 <br /> The USTs removed were identified as follows: <br /> Tank #1: 4,000 gallon diesel. Lined single wall steel construction. <br /> Tank #2: 4,000 gallon unleaded gasoline. Lined single wall steel construction. <br /> Tank #3: 4,000 gallon diesel. Lined single wall steel construction. <br /> Figure 2 depicts the former locations of the USTs. The removed lines and dispensers remain <br /> on site. Vent lines will be removed during the upcoming installation of replacement tanks. <br /> Soil Sampling <br /> Under the direction of PHS/EHD, Kiff Analytical personnel collected samples from native soil <br /> within the UST it and from beneath the former dispenser island on February 3 1999. One <br /> P P m'Y , <br /> sample was collected from beneath the west end of each tank at a depth of approximately 13 <br /> feet. In addition one sample was collected from a depth of approximately 14 feet from beneath <br /> the east end of Tank #3. Two samples were collected from a depth of approximately 3 feet <br /> beneath the dispenser island. Sampling locations are depicted on Figure 2. <br /> The samples were transported under chain of custody documentation to state-certified Kiff <br /> Analytical (FLAP#2236) where each was analyzed for total petroleum hydrocarbons as gasoline <br /> (TPHg) and total petroleum hydrocarbons as diesel (TPHd) by EPA Method 8015; for benzene, <br /> toluene, ethylbenzene and xylenes (BTEX) by EPA Method 8260; and for oxygenate additives <br /> by EPA Method 8260. One four-point composite soil sample was collected from stockpiled soil <br /> and analyzed per above with the addition of total lead by EPA Method 6010. <br /> Analytical results indicate soil in the tankpit and beneath the former dispenser island is impacted F <br /> by petroleum hydrocarbons. Analytical results are summarized in Table 1. Laboratory date <br /> sheets and chain of custody documentation are included in Attachment C. <br /> Tankpit Backfill <br /> The tankpit remains open pending disposal of contaminated soil, investigation of the extent of <br /> soil contamination and possible overexcavation. A Workplan is being submitted under separate <br /> cover for a subsurface investigation. <br /> k <br /> w001=Y �F.chtl ' ull.ttr <br />
