Himanshu Mehta, P.E. 7 May 2008 Page 2 Geosyntec consultants report for the 8,000 -gallon AST located at the landfill, (vii) preparation of a Phase I ESA for the parcel located west of the Gifford Convenience Center, and (viii) completion of a NEPA Categorical Exclusion Package in accordance with 23 CFR Part 771.117. Please be advised that since the 8,000 -gallon AST along Gifford Road is double -walled, pursuant to Rule 62-761.800(4)(b), Florida Administrative Code (F.A.C.), a formal closure assessment will not be required for this location; however, IRC has requested limited soil and groundwater sampling to document that the AST located on the parcel has not negatively impacted site soil and/or groundwater. We have developed a task -based approach to accomplish this work in an organized and cost- effective manner. Additionally, Geosyntec met with petroleum subcontractors, PR&D, HCC, and FECC to obtain cost estimates for the work to be performed by a licensed pollutant storage tank contractor. HCC provided the lowest total bid at $57,295 (with an estimated additional $1,500 for bollards), PR&D total bid was $100,703, and FECC did not submit an estimate for the work. HCC was selected to provide subcontractor services on the referenced project. The remainder of this letter provides a description of the proposed scope of work. A budget estimate to accomplish the work described herein is provided in Exhibit 2. SCOPE OF WORK Task 1— Landfill AST Fueling Area Design Task 1 includes costs associated with the preparation of a set of design drawings for the proposed fueling area at the IRC landfill. It is anticipated that three drawing sheets will be prepared, including a plan drawing which shows the proposed grading and dimensions of a concrete pad with turn around area, ramp, callouts for curb details (if warranted), cross-sections location, control points, etc. and two sheets with cross-sections, coordinate table for control points, and details such as curb, area inlets, best management practices, etc. Geosyntec will provide draft copies of the drawing set for IRC SWDD review prior to finalizing the drawings and initiating any construction activities. Task 2 — Gifford Road Soil and Groundwater Sampling, AST Removal and Relocation Task 2 includes costs associated with the relocation of the approximately 12,000 -gallon double - walled AST to the IRC landfill. Prior to AST closure, Geosyntec personnel will mobilize to the site and perform four soil borings around the AST. Continuous soil samples will be collected from land surface to the water table and screening with a flame ionization detector (FID). Based XR08051 R/CCR08045 R.DOC engineers I scientists I innovators
