Basewide Engineering Evaluation-Cost Analysis for Soil Vapor Extraction. General Evaluation Document
Abstract
This Engineering Evaluation-Cost Analysis (EE/CA) document supports soil vapor extraction (SVE) as the preferred alternative for a basewide, non- time-critical removal action to remove volatile organic compound (VOC) contamination in soils at McClellan Air Force Base (McAFB). The National Contingency Plan (NCP) requires the lead agency to conduct an EE/CA or its equivalent for non-time-critical removal actions (40 CFR 300.415). The EE/CA process is a comparative analysis of removal action alternatives and is recorded in the EE/CA document for public review and comment. A conventional EE/CA document generally supports a decision to take a removal action at a specified site or group of sites. McAFB and the regulatory agencies have modified the conventional EE/CA document to facilitate decision making and to streamline the administrative process in the McAFB Installation Restoration Program (IRP). This is accomplished by focusing on the basewide applicability of a single technology (SVE in this case), rather than on a single site. This General Evaluation Document establishes a site selection methodology that defines site conditions conductive to early action and to effective SVE application. Site Specific Documents will be written, as needed, to demonstrate that SVE should be applied in specific cases. At present, several contaminated areas have been identified for early application of SVE, and additional sites are expected to be identified in the future as site investigation and evaluation continues.
