Final Work Plan for an Engineering Evaluation/Cost Analysis in Support of the Risk-Based Approach to Remediation at Area D, Ellsworth Air Base, Rapid City, South Dakota

摘要

This work plan was prepared by Engineering Science, Inc. (ES) and describes the scope of work required for the collection and analysis of data to complete an engineering evaluation/cost analysis (EE/CA) in support of a risk- based remediation decision for soil and ground water contaminated with fuel hydrocarbons at Area D Bulk Fuel Storage (Area D) at Ellsworth Air Force Base (AFB), Rapid City, South Dakota. Area D, a petroleum, oil, and lubricant (POL) tank farm, is part of the base-wide fuel distribution system. This work plan is the equivalent of a treatability study test design (TSTD) for the field test of the risk-based approach to the remediation of Area D. This innovative technology is sponsored by the Air Force Center for Environmental Excellence (AFCEE) at Brooks AFB, under contract F41624-93-C-8044, 'Risk-Based Approach to Fuel Spill Remediation'. The Area D demonstration is a component of a multisite initiative being sponsored by AFCEE to demonstrate how quantitative fate and transport calculations and risk information based on site-specific data can be integrated to quickly determine the type and magnitude of remedial action required at a site to minimize contaminant migration and receptor risks.
