Document Summary

This is a Level 4 Limited Scope Remedial Action Plan (LSRAP) prepared by FRS Environmental Remediation, Inc. (dba The FGS Group) for the Florida Department of Environmental Protection's Bureau of Petroleum Storage Systems. The document addresses remediation of the Springhill Road Grocery facility located at 6011 Springhill Road, Tallahassee, Leon County, Florida (Facility ID: 37/8944286). The plan was developed under Preapproval Task Assignment GC723-031D and follows a pilot test conducted in December 2012, with a Pre-RAP meeting held on February 11, 2013.

The remedial action strategy employs a combined air sparging (AS) and soil vapor extraction (SVE) system to address remaining soil and groundwater contamination following previous large-diameter auger (LDA) excavation activities. The system design includes thirteen air sparging wells installed to 38 feet below land surface and five new SVE wells plus twelve existing LDA recovery wells installed to 20 feet depth, all operating simultaneously. The total estimated capital cost is $296,500, with four-year active remediation operations and maintenance costs of $507,600. A subsequent one-year post-remedial action monitoring period is estimated at $21,000, and system decommissioning and well abandonment costs are projected at $42,000. The total project cost including all phases is $867,100. The estimated project life is three to four years from installation completion, with the agreement ceiling amount set at $870,000 and an initial funding increment of $879,271.20, with initial milestone funding beginning June 1, 2013.
