tf 40 • 40 ATTACHMENT B PE OF SERVICES AND SCHEDULI INDIAN RIVER COUNTY SOLID WASTE DISPOSAL DISTRICT ENGINEERING SERVICES FOR LANDFILL GAS TO ENERGY FEASIBILITY STUDY Project Understanding The Indian River County Solid Wastc Disposal District (SWDD) operates a Class I Landfill and other solid waste management facilities in Indian River County. Decomposition of municipal solid waste results in the production of landfill gas. Landfill gas is typically composed of A0- 50°fo methane, 40-50% carbon dioxide and small amounts of nitrogen and other compounds. Landfill gas has been used for a number of years as an energy source for numerous applications ranging from boiler fuel to electrical power generation. In order to determine the feasibility of converting landfill gas from the Indian River County landfill into a useable form of energy, a study of gas production and various use options should be undertaken. Landfill gas generated by the landfill would be extracted from the landfill through the installation of a series of wells or collectors. These wells would be installed across the surface of the landfill. A vacuum source (blower) would be installed to withdraw the gas from the landfill at a controlled rate and deliver it through a pipeline to a point of use. As a backup to the energy system, a landfill gas flare would be installed to burn landfill gas during maintenance periods or other system interruptions. Task 1.0 - PREPARATION OF FEASIBILITY STUDY In order to determine the best option, or mix of options for energy generation, CDM would perform the following investigative steps: Conduct computer modeling of gas production rates and predict the amount of gas available presently and for 20 years into the future. Review the energy using equipment now installed and planned for the future at Indian River Correctional Institution, and other potential landfill gas customers. Establish conceptual designs for development and distribution of the gas to IRCI. Development schemes should contemplate using the gas for reciprocating engine electric power generation, gas turbine or fuel cell electric power generation. Differences in cost of equipment for both the developer and the user will be examined for these various uses.
