control over facility operations than if a private facility were simply encouraged to set up operations and accept C &D wastes originating in Orange County. Other public - private partnership arrangements are also possible. Any public - private arrangement would require using a contractor with a proven track record in this arena due to the high risk of such operations and high failure rate acrooss the nation. There is often a differential between reported true recycling and actual practice. For example materials reported as "beneficial fill" may go to improve a road on -site or fill in a " low area". Another approach could entail building, owning and operating our own facility. Under this sceanrio, any revenue from tipping fees or sale of materials would come to us. In December 1996, staff conducted an analysis of constructing a semi - automated construction and demolition waste recycling facility with some hand - picking and some automated sorting.. (The whole December 1996 memorandum is available on request) An update to the costs of the facility shows an estimated first year cost of $2.09 million including land, equipment, labor and maintenance. Annual costs including an eight year amortization would be about $650,000. The cost per ton estimate is increased from $53.00 per ton to about $56 per ton, assuming one- third of incoming materials can be recycled, including wood, metal, drywall and reusables. This does not include the heavy construction debris of rock, block, brick and concrete that could be used as aggregate in road construction because the crushed mixed inert loads won't passs NCDOT compaction regulations and the cost of locally available rock is currently too low to make crushing the inert fraction a worthwhile endeavor. Inert debris is much cheaper to landfill. If this material becomes marketable, the percentage recyclable could increase to an estimated 70 %. Key issues: Siting, designing, building and operating such a facility is a major undertaking. Most facilities investigated take in far more than the 30,000 tons per year of C &D we average. Many restrict materials to exclude the heterogeneous mix with accept to landfill now. Cost: Processing facilities are capital and equipment intensive. They can also employ a significant amount of manual labor to hand -pick materials, high grade metal loads and perform the many other tasks associated with such a maintenance - intensive operation. A more detailed, updated cost estimate could be provided if the Board were interested in this approach to managing C &D. D. Differential Fees/Bans It is certainly feasible to extend the current set of differential fees and bans at the landfill to include a greater variety of materials than the yard waste and corrugated cardboard now banned from landfilling. Similar bans /penalties could be extended to include regulation of haulers and 31
