Himanshu Mehta, P.E. 7 May 2008 Page 3 Geosyntec consultants upon the FID responses, one representative soil sample (location with highest FID response or location immediately adjacent to dispenser) will be submitted to a fixed base analytical laboratory. The collected soil sample will be analyzed for BTEX/MTBE by EPA Method 8260, PAHs by EPA Method 8310, and TRPH by FL -PRO. In addition to the soil samples, Geosyntec will provide oversight and sampling of a temporary monitoring well installed using a direct -push technology (DPT) drill rig. Collect groundwater samples from the temporary monitoring well will be laboratory analyzed for BTEX/MTBE by EPA Method 8260, PAHs by EPA Method 8310, total lead by EPA 6020 or equivalent, and TRPH by FL -PRO. Geosyntec will provide oversight and coordination with our proposed subcontractor, HCC. The AST will be unbolted from its concrete pad, rigged for loading, and loaded onto a transport vehicle with a crane. The AST will then be transported to the IRC landfill and offloaded with a crane. Upon removal of the AST, the existing concrete pad (dimensions of approximately 40 ft by 10 ft by 12 -inches thick) will be broken up, bumper posts removed, and the debris will be transported to the IRC landfill for disposal. The area where the concrete was removed will be backfilled, as warranted, and re -graded to promote drainage. Task Assumptions: • No costs are included for the disposal of the concrete material or bumper posts at the IRC landfill; it is assumed that any tipping fees associated with the concrete/debris disposal will be handled internally by IRC SWDD. • The double -walled AST meets the closure exemption requirements of Chapter 62- 761.800(4)(b), F.A.C. Collected soil and groundwater samples are being collected as a component of due diligence activities associated with the parcel. • The AST is assumed to be empty, additional budget may be required if a vacuum truck is required to empty the AST contents. • No costs are provided for any testing/certification of the integrity of the AST. • No costs are included for paving the area where the AST is removed. Task 3 — IRC Landfill Fueling Area Construction and AST Installation Task 3 includes costs associated with the construction of the fueling area by PR&D, Geosyntec inspections, the placement of the AST, and the installation of a high-speed fuel dispenser (two dispensers) with a card reader system, card encoder, modem and provision of 100 cards to IRC SWDD. Prior to construction activities, HCC will obtain construction permits from IRC. For XR08051 R/CCR08045 R. DOC engineers I scientists I innovators
