Table 4-14 identifies the capital and annual operating costs for typical capac- ities of facilities and programs that could be expected for development in the region (see the development programs for waste reduction and resource recovery). The annual operating cost includes the debt service which has been amortized over 20 years. Costs For The Waste Reduction and Resource Recovery System, 1990 A waste management system tf,at could meet that goal is presented in Table 4-15. The proposed waste management system includes combustion facilities, composting sites for yard waste, co -composting facilities, transfer stations, region -wide source separation programs and three new landfills. By far the most expensive waste facilities are the combustion units, either mass burn or RDF. The primary costs for combustion units are for the boilers, heat recovery systems and pollution control equipment. Some savings on capital expenditures are realized if existing boilers are retrofitted to burn RDF. The combustion and processing components of the waste reduction/resource recovery development program will cost about $220 million. The co -composting component of the waste reduction and resource recovery devel- opment program calls for two co -composting facilities to manage the heavy organic residue from RDF facilities. These facilities are less costly to con- struct and operate than the combustion facilities. Total capital cost for two co -composting facilities with a capacity of 300-600 tons per day are about $40 million. The region will also need many sites to compost yard and garden wastes. The most significant cost of these facilities are the operating costs. There is little capital cost involved based on a system that utilizes available public land. County or local public works departments are likely operators of these facilities. Recycling programs and facilities, similar to yard and garden waste composting facilities, have greater operating costs than capital costs. By far, the largest cost of recycling programs are the collection costs. One or two recy- clables processing facilities are needed in the region !, manage daily about 1,000 tons of recyclables. Capital costs for equipmen,d recyclable process- ing facilities are about S7.5 million. Existing recy ie processing opera- tions could be used, expanded or modified thereby redu ng public costs. Several transfer stations will likely be needed within the region to consoli- date waste or recyclables for shipment to processing facilities. It is diffi- cult to determine the number of facilities that will be needed until the other centralized processing facilities are located. Occasionally, the transfer stations may be physically linked with the RDF processing facilities. For planning purposes the waste recovery/resource recovery development program estimates that five transfer stations would be built that would handle about 500 tons per day. The total capital costs of the proposed system are about $345 million. Annual operating costs are about $122 million. The annual household cost for refuse disposal would increase by about $30 to $55 from the current annual cost of $95. The commercial and industrial sector would incur an overall increase of about $34 million or $35 per ton for refuse disposal assuming one-half of the waste generated in the region is of commercial or industrial origin.
