Exhibit 1 - LANDFILL CLOSURE, LANDFILL GAS <br />MANAGEMENT SYSTEM EXPANSION AND CELL <br />CONSTRUCTION PROJECTS <br />The consultant/engineer should specifically provide FDEP permitting and detailed construction <br />design and bid documents for landfill closure, landfill gas system expansion and cell construction <br />projects at the Indian River County Landfill facility over the next 10 years. The design, permitting <br />and construction of Segment 3 Cell 3 is in the capital improvement plan for the 2022/23 — <br />2023/24 Fiscal Year. Ancillary services related to leachate equipment, transfer or treatment, well <br />installation/abandonments, swale/road improvements and other services that are part of or <br />related to the major closure or cell construction work is considered part of the scope of work. The <br />requirements for these projects include: <br />A. FDEP Permit Form(s) <br />Preparing and completing the FDEP Form 17-701.900(1) titled "Application for a Permit to <br />Construct, Operate, Modify or Close a Solid Waste Management Facility" and will include the <br />engineering reports and drawings in support of the permit application as required by the form. <br />Prepare and complete FDEP forms as necessary for projects during the scope of this agreement. <br />B. Class I Landfill Partial Closure Design and Permitting <br />a. Consists of the design and permitting of the partial closure and GMS <br />upgrade/expansion of the Segment 3 (north and south slopes) landfill up to final <br />design grades ranging from approximately El. 17o ft to El. 18o ft National <br />Geodetic Vertical Datum of 1929 (NGVD 29). <br />b. Layout and grading of the side slopes and top decks of Segment 3; <br />C. Specification of components and materials of the final cover system (vegetative <br />layer, cap protective layer, and geosynthetics); <br />d. Evaluation of percolation through and liquid head build-up in the final cover <br />system using the hydrologic evaluation of landfill performance (HELP) model; <br />e. Evaluation of stability and settlement of the final cover system; <br />f. Design of the final cover drainage system to collect and convey the water that <br />percolates through the vegetative and cap protective layers; <br />g. Design of the surface water drainage system to collect and convey the storm water <br />runoff from the final cover system to the perimeter toe ditch; <br />h. Development of typical final cover system details (configuration of the final cover <br />system at the side slope swales, and other details as appropriate) as required for <br />the permit application; <br />i. Development of a construction quality assurance (CQA) plan; <br />j. Development of technical specifications; and <br />k. Development of financial assurance calculations. <br />C. Design for Expansion of the Landfill Gas Management System <br />Segment 1, the Infill Area, Segment 2 and Cell 1 of Segment 3 of the IRCL has an existing landfill <br />Gas Management System consisting of vertical and horizontal gas extraction wells, gas collection <br />lateral and header pipes, a condensate management system, a blower system, and flare station. In <br />addition, side -slope collectors have been utilized on the east slope of Segment 3 Cell 1. Using the <br />currently permitted GMS design and based on the existing conditions at the site and current <br />projected waste filling rates and waste stream properties, the Consultant will design the GMS <br />expansion to cover the proposed partial closure areas and design upgrades to optimize the existing <br />GMS. This will include tying in the existing GMS components with the future LFG collection <br />system to the extent practicable. The GMS should be designed to utilize existing GMS features to <br />16 <br />
