File Report <br />April 7, 1998 <br />EPA method 8020*. <br />*Note: RCP is not responsible for closure or subsurface leakage from this facility's tanks or piping under the terms of it's <br />lease agreement and is responsible for only diesel identified in the spill report. Regardless of this fact, RCP felt it <br />necessary to identify any and all contamination possible in this area for its "worst case" determination. <br />Analytical Results <br />Results of these analysis showed limited impact to the subsurface soils at the suspected <br />primary entry point of the suspected diesel contamination. Table 1 shows elevated <br />levels of diesel and what appears to be weathered gasoline at the point of impact. <br />However, these levels are substantially reduced within the first foot of depth. <br />Table 1 <br />Analytical Results <br />Sample Diesel Weathered Benzene Toluene Ethyl Total <br />I.D.

The following factors were used in RCP's review. <br />5 <br />RCP0407
