Mr. Himanshu Mehta 15 December 2009 Page 5 • compile a list of enforcement actions; • provide a signed and sealed boundary survey, legal description and topographic survey of the property in accordance with Rule 62-701.730(2)(b), FAC; • calculate the remaining landfill life; • prepare a financial assurance cost estimate for closure and long-term care of the landfill in accordance with Rule 62-701.730(11)(b), FAC and complete FDEP Form 62- 701.900(28); and • complete the required FDEP Form 62-701.900(1), and prepare a transmittal letter to FDEP that summarizes the permit renewal package. We propose to combine this renewal permit application with the Substantial Modification Permit Application for the Segment 2 Landfill Lateral Expansion in an effort to save SW -DD an application fee of $20,000. Geosyntec will provide four complete copies of the application to FDEP Central District and two copies to SWDD. Phase 3 — ERP Modification Permit Application Under this phase, Geosyntec will prepare an ERP modification pen -nit application for submittal to FDEP. Geosyntec will model the drainage of storm water runoff at the landfill site for 25- year/24-hour design storm event, using the latest version of the Interconnected Channel and Pond Routing (ICPR) Model, developed by Streamline Technologies of Winter Park, Florida. This model was used in previous studies to perform hydrologic and hydraulic analyses of storm water management system for the IRC landfill site. Geosyntec will base the modeling on existing basins system developed by others and trapezoidal perimeter ditch configuration. This basins system will be modified to reflect the changes in the site configuration and the anticipated changes in the total impervious area of each of the basin. The modeling output will be used to size the conveying conveyance channels to ensure that the landfill site complies with the permit requirements. Geosyntec will prepare designs for the perimeters ditch to convey stormwater runoff from a 25 -year 24-hour storm, a retaining wall to provide additional ditch capacity around the leachate lift station and a section of paved road to provide access to the groundwater and landfill gas migration monitoring wells. Geosyntec will prepare the Modification Permit Application for the landfill site's ERP. The application will include the engineering reports and drawings in support of the permit application in accordance with Chapter 62-330 FAC. Geosyntec will provide four complete copies of the application to FDEP Central District and two copies to SWDD. 1L90232 IRC LF Permittina.doc engineers I scientists I innovators
