Comprehensive Plan Solid Waste Sub -Element To reduce solid waste volume, the County has contractors that provide for tire removal and for yard waste grinding and removal services. While tires are hauled off-site, a portion of the ground yard waste is used for daily cover on the Class I landfill, and the remaining yard waste is hauled off-site. According to FDEP solid waste reports, Indian River County and its adjacent counties have seen slight, but steady, increases in the per capita tonage of solid waste disposed of each year. The average tons/capita/year for the State of Florida is nearly double that of the County's. In order to further reduce the amount of solid waste being disposed of at the landfill, there are two principal options. First, the County can expand its existing recycling system, disposing the remainder of solid waste in the landfill. Second, the County can contract with a regional landfill to transfer solid waste to that disposal site. Another option for reducing the amount of solid waste requiring landfill disposal is Waste to Energy (WTE) conversion. WTE converts solid waste to energy. This is a new technology that requires an in depth study to determine if it could work for the County. With the proposed INEOS New Planet Bio project, the SWDD has initiated the process of establishing a WTE facility to convert solid waste to energy and ethanol. In the future, the county should assess the performance of that facility and should support the project if the assessment shows that the project is successful. Proiection of Future Demand and Landfill Capacity Since the time horizon of this Comprehensive Plan update is 2030, future solid waste demand must be projected to that year. For solid waste, demand projection is based on two components: population growth and solid waste generation rates. Landfill Capacity One of the County's principal responsibilities is to ensure that sufficient landfill capacity is available for disposal of processed or raw waste. According to the Solid Waste Master Plan, the County must maintain a disposal capacity of at least three years to allow for sufficient time to permit and construct a new active landfill segment, when necessary. Currently, the SWDD utilizes two approaches to ensure that there is adequate landfill capacity. These are: (1) developing new landfill capacity, and (2) implementing programs to reduce the demand for landfill disposal. To increase the disposal capacity for Class I waste and C&D debris, the SWDD has optimized the design of the Class I landfill between Segments I and II. Also, the SWDD recently obtained permits for additional C&D disposal on the side slopes of Segment I to increase the C&D disposal capacity. To increase the disposal capacity of the landfill footprint area, the SWDD obtained permits for a vertical expansion of the Class I landfill to elevation 185 feet National Geodetic Vertical Datum (NGVD). Construction of the vertical expansion began in May 2009 and was completed in October 2009. Besides those initiatives, a 70 -acre Segment III Class I cell is being designed and permitted for future construction. This cell will accommodate another 8.4 million cubic yards of Class I waste and C&D debris. SWDD has also obtained permits for a 33 -acre component of the Segment III landfill Community Development Department Indian River County 21
