Mr. Himanshu Mehta 11 July 2008 Page 3 design and permit the closure system for the C&D placement on Segment 1 slopes in order to meet the closure requirements of the solid waste regulations. In June 2006, FDEP issued the SWDD with a permit for the vertical expansion that includes the construction of a liner system over the top deck of Segment 1 and raising the final elevation of the entire lined area of the Class I landfill to elevation 185 ft NGVD (Permit Modification No. 5031-0128769-012). This additional permitted capacity extends the life of the Class I landfill until January 2011, based on projected waste acceptance rates. As previously discussed, the current FDEP permits for C&D placement on Segment 1 with 5 percent top deck slopes is projected to reach final grades in March 2009 before the Class I landfill vertical expansion can be constructed. However, the vertical expansion represents the next phase of the scheduled capacity additions to the Class I landfill. Its projected delay due to the decline in the deliveries of C&D debris for landfill disposal, places it on the critical path of the capacity addition schedule. Geosyntec prepared a Minor Modification Permit Application for the reduction in slope of the overlay liner on top of Segment I to expedite construction of the vertical expansion. The application is currently on file with the FDEP and is under review. Also, Geosyntec has begun the construction procurement services for the vertical expansion. On 10 April 2008, an inspection conducted by the FDEP at the IRCL noted the seepage of leachate from the south slope of the Class I landfill. Subsequent inspections also discovered leachate seepage on the north slope of Segment 2. In response to the FDEP's concerns, Waste Management (WM) informed the FDEP that a final cap would be constructed following the completion of the north slope of Segment 2 to El. 95 ft NGVD. On 19 June 2008, the SWDD requested, via email, that Geosyntec submit a proposal to provide engineering services for the construction of the partial closure of the north and south slopes of Segment 2 and the Infill Area to be executed concurrently with the construction of the vertical expansion. This proposal describes services to be provided in fulfillment of that request. PROPOSED SCOPE OF WORK This project includes professional engineering services for design, permitting, and construction of the partial closure of the north and south slopes of the Infill and Segment 2 of the Class I landfill at the IRCL facility. The scope of work is based on the requirements of Chapter 62-701, Florida Administrative Code (FAC) and Geosyntec's understanding of the project based on information provided by the SWDD.
