<br />March 2, 2007 <br />Page 2 <br />' Due to the depth of the pipeline and the alluvial nature of the soil, a significant excavation was <br />required to uncover and repair the pipeline. Between October 30'x' and November 2"d . 2006, <br />approximately 468 cubic yards of contaminated soil were excavated and segregated on site for later <br />' disposal. Clean overburden was also segregated and was used on site for construction till in the <br />immediate area of the release. <br />' Fig e roll off boxes were provided by BFI/Allied Waste to store the contaminated soil. When these <br />boxes were filled, the remaining soil was placed on plastic sheeting within a bermed area and <br />covered with plastic sheeting. Soil samples from the contaminated soil stockpile and roll off boxes <br />\?ere collected and analyzed. Based on these data, waste profiles were submitted to Waste <br />' Management and BFI/Allied Waste for approval to transport the contaminated soil to their facilities. <br />Upon approval, the five roll off boxes (approximately 36 yards) were transported to BFI's Tower <br />Road landfill for disposal. The "bulk" soil was loaded into dump trucks and transported to Waste <br />t Management's Buffalo Ridge landfill in Keenesburg, Colorado landfill for disposal on December 6'h <br />and 7'h. 2006. Disposal at the Keenesburg landfill was considered to be more efficient and cost <br />el'Iectke than the To\\er Road landfill. Manifests forthese shipments are attached. <br />RMPS mobilized five vacuum trucks to the release site to collect the gasoline from the excavation <br />and from the pipeline. In addition to the gasoline collected, a significant quantity of water and slurry <br />were captured with the gasoline since it was floating on top of the bentonite slurry. The vacuum <br />trucks were sent directly to RMPS Dupont, Colorado terminal to offload the gasoline/slurry/water <br />mixture.
