Ms . Polly Kratman GeoSyntec Consultants <br /> Indian River County <br /> 7 June 2005 <br /> Page 7 <br /> (terraces) will be evaluated . GeoSyntec will evaluate total and differential settlements <br /> in the components of the liner and cover systems of the landfill . <br /> A hydrologic and hydraulic analysis will be performed to evaluate the peak runoff <br /> rates and volumes from the proposed final cover system. Hydraulic analysis and design <br /> of the components of the final cover drainage system will be performed . The final <br /> cover system drainage layer will be designed to : (i) minimize infiltration into the <br /> existing and new landfills ; (ii) minimize erosion of cover materials ; (iii) carry the <br /> calculated flow and thereby ensure stability of the cover system ; and (iv) comply with <br /> the cover requirements . <br /> For budget estimating purposes , it has been assumed that no further geotechnical <br /> and hydrogeological investigations are needed to complete the permit application for <br /> the vertical expansion and that available data are adequate for settlement and slope <br /> stability calculations . <br /> OperatingPlans <br /> The CQA Plan will specifically address geosynthetics installation, soil <br /> construction, preparation of record drawings , and reporting requirements in accordance <br /> with applicable sections of Chapter 62 -701 , F . A . C . The Operations Plan will address <br /> the waste filling sequence during the vertical expansion, and will be prepared with input <br /> from Waste Management, Inc . of Florida (WMIF) , IBC ' s current contract operator of <br /> the Class I landfill . The Leachate Management Plan will address changes to the <br /> leachate collection, transmission and disposal system , and will specifically address <br /> relocation of the existing lift station for the Infill Area. The Closure Plan will be <br /> revised to incorporate changes resulting from the vertical expansion, and will include a <br /> new financial assurance cost estimate for closure and long-term care of the proposed <br /> expansion. <br /> FDEP Class I Landfill Permit Application <br /> GeoSyntec will prepare the application for a Class I Solid Waste Disposal Facility <br /> (Permit Application) . The Permit Application will include the engineering reports, <br /> permit drawings and operating plans required in accordance with Chapter 62 - 701 , <br /> F .A. C . The Permit Application will be signed and sealed by a registered professional <br /> engineer in the State of Florida. <br /> XL05065VI050010-final <br />
