AMENDMENT NO.1 <br />WORK ORDER NUMBER 44 <br />LANDFILL GAS FLARE SKID IMPROVEMENTS AND PIPELINE EXTENSION <br />EXHIBIT A <br />SCOPE OF WORK <br />PROJECT UNDERSTANDING <br />Indian River County (County) Solid Waste Disposal District (SWDD) currently relies on <br />a candlestick flare for landfill gas (LFG) emissions. The current blower flare skid was <br />installed in 2004 and is in need of updating and reconfiguration for overall performance <br />and efficiency, and to accommodate the renewable natural gas (RNG) project that is in <br />development with the Indian River Eco District (IRED). In addition, SWDD is working <br />with a third -party to install a leachate evaporation system that may utilize landfill gas as a <br />fuel source. To accommodate the RNG and evaporation projects, modifications to the LFG <br />skid and an extension to the LFG pipeline are required. The proposed modifications will <br />improve the LFG collection and control system by providing reliable vacuum pressure to <br />the gas wellfield and ensure continuous delivery of dry, pressurized LFG to the evaporation <br />and RNG projects. <br />Kimley-Horn and Associates, Inc. (Consultant) has partnered with BioGas Engineering <br />(BioGas) to design, permit and bid the proposed improvements. The BioGas proposal is <br />incorporated herein and provided as Attachment 1 to this Scope of Work for informational <br />purposes. The Consultant team will design, permit, and prepare a bid package for the <br />proposed improvements as outlined in the following Scope of Services. Services during <br />construction are not included in this Scope of Services. <br />SCOPE OF SERVICES <br />Task 1: Landfill Gas Pipeline Design <br />Subtask 1.1.3 has been amended as noted below. <br />Subtask 1.1 Preliminary Design Activities <br />1.1.1 Alignment for Survey Purposes <br />No changes. <br />1. 1.2 Survey <br />No changes. <br />1.1.3 Geotechnical Data <br />The consultant will modify the subcontract with a local geotechnical engineering <br />consultant who routinely performs work for the County on the SWDD property to <br />perform additional services to collect geotechnical data in several additional <br />176 <br />
