Removal- Alternatives <br /> i--„ Unrestricted excavation - As discussed in the Problem <br /> �-- Assessment Report, we anticipate that soils beneath the store <br /> contain detectable concentrations of gasoline hydrocarbons at or <br /> above targeted clean-up levels. Unrestricted excavation would <br /> require completely closing the site, possibly demolishing the <br /> f � 1 store, and removing existing underground tanks and parking pave- <br /> ment.' if operations were to continue after remediation, the . <br /> ' facility would need to be completely rebuilt. Therefore, unre E <br /> f stricter? excavation is not believed practical and is refected. <br /> Restricted Excavation - Restricted excavation would <br /> require excavating soils outside the footprint of the convenience <br /> store. such excavation could be performed in conjunction with <br /> the planned removal of the underground gasoline storage .tanks. in <br /> the front of the building. The store would possibly be closed <br /> temporarily. It is. estimated that approximately 1100 cubic yards <br /> -of--soil would need --to. be-excavates: from--the southern-and-eastern <br /> sides of the building. Excavation would be carried out using <br /> standard construction e <br /> r <br /> quipment and practices_. This alternative <br /> z' <br /> of soil removal is believed practical. <br /> r <br /> :. 14 <br /> e. <br /> r., <br />
