WORK ORDER NUMBER 44 LANDFILL GAS FLARE SKID IMPROVEMENTS AND PIPELINE EXTENSION EXHIBIT A SCOPE OF WORK PROJECT UNDERSTANDING Indian River County (County) solid waste disposal district (SWDD) currently relies on a candlestick flare for landfill gas (LFG) emissions. The current blower flare skid was installed in 2004 and is in need of updating and reconfiguration for overall performance and efficiency, and to accommodate the renewable natural gas (RNG) project that is in development with the Indian River Eco District (IRED). In addition, SWDD is working with a third -party to install a leachate evaporation system that may utilize landfill gas as a fuel source. To accommodate the RNG and evaporation projects, modifications to the LFG skid and an extension to the LFG pipeline are required. The proposed modifications will improve the LFG collection and control system by providing reliable vacuum pressure to the gas wellfield and ensure continuous delivery of dry, pressurized LFG to the evaporation and RNG projects. Kimley-Horn and Associates, Inc. (Consultant) has partnered with BioGas Engineering (BioGas) to design, permit and bid the proposed improvements. The BioGas proposal is incorporated herein and provided as Attachment 1 to this Scope of Work for informational purposes. The Consultant team will design, permit, and prepare a bid package for the proposed improvements as outlined in the following Scope of Services. Services during construction are not included in this Scope of Services. SCOPE OF SERVICES Task 1: Landfill Gas Pipeline Design The Consultant will prepare the design of an LFG pipeline to deliver LFG from the flare skid to the proposed location of the evaporation system (adjacent to the existing biosolids dewatering facility). The route of the pipeline will be identified in Task 1 and utilized as the basis of this design. The design will provide for a common utility trench that will house: 1. LFG transmission line from flare to the evaporation system; 2. Compressed air line for pneumatic valves and pumps (if required); 3. Any other future lines required by the County; and 4. Any control conduits required to communicate between new flare skid and the evaporation system. This task will include route analysis, site survey, geotechnical data collection, site survey details, trench detail, pipe sizes, conduit types/sizes, roadway crossing details, pavement restoration cross sections/details, maintenance of operations/traffic information, erosion Page 1 of 8
