This report is a technical evaluation of the impact of risk-based corrective action (RBCA) policy issues on the cost of corrective measures at leaking underground storage tanks (LUST) sites in the state of Florida. Technical information regarding environmental site conditions, remediation requirements, and related costs can greatly facilitate development of appropriate and cost-effective risk management policies. To this end, this study was undertaken to provide the Florida Department of Environmental Protection (FDEP) and other concerned parties with quantitative information related to implementation of RBCA policies for the storage tank cleanup program, as required by the recent legislative amendments (Chapter 96-277 Florida Statutes, CS for HB1127).
This project was commenced in January 1996, and preliminary findings were reviewed with representatives of FDEP and the Dade County Department of Environmental Resource Management (DERM) in June 1996. The study was modified thereafter to incorporate recommendations regarding addition/modification of policy issues and model sensitivity analyses, and a draft report was issued in October 1996. This final report has been modified to address written comments received from both the FDEP and the U.S. EPA Office of Underground Storage Tanks (OUST) on the draft report (see Attachment B). Throughout the course of this investigation, the findings have been used for technical guidance on various issues.
