7 demolition waste since that material may be heavier, more abrasive and generate more _ dust thus requiring more durable floors and walls and dust control than a facility for only mixed solid waste. ' Estimatins the cost of a Transfer Station 1=aciliry cost varies with size, number of bays, types of equipment, design and amenities. From discussions with engineering firms who have designed transfer stations recently in North Cazolina and nationally, we believe that a facility of 8,000 to 10,000 square feet with a minimum of two bays would be capable of handling the waste stream of 66,500 tons per year projected to be generated in Orange County by 2006, around the year the current landfill is projected to close. Facility costs could be in the range of 5200 per square foot including~all site development cosu and utilities, but exclusive of land costs. Land costs could be paid out of a fund already established for that purpose. Averaging the projected size at 9,000 square feet and estimating the cost at 5200 per square foot, the capital cost of the facility would be around S 1.80 million. Equipment, according to WE.STON's report could cost another 5300,000. Total capital cost for a transfer station would then be about 52.1 million. The transfer station could be expected to last twenty years with a 1090 annual maintenance cost to replace equipment and floors. Annualized capital cost would then be 51-15,000 over twenty years excluding debt ~~~ service. ~ ~. Operations costs are estimated at 5350,000 to include eight full-time people, utilities, benefits, repairs, leachate collection, and administration to operate approximately the same 54 hours per week that the landfill is now operated. Operating cosu do not include the post~losure monitoring costs estimated by Joyce Engineering at S50,000 annually. By federal law, landfills must be monitored for thirty years after closure. The above-stated costs do not include cost of hauling and tipping at the remote disposal site that would accept waste from the transfer station. Those cosu .range from the 524.05 ger ton thaz the Ciry of Durham recently negotiated with Carolina Container Corporation for hauling and tipping fees to the S27.~0 per ton tipping fee only offered to the Orange Regional Landfill at the Browning Ferris Industries landfill in Sampson County plus hauling costs of S I7.S0 per ton estimated by WESTON in their July 1995 report on out- of-county disposal facilities. Hauling and tipping fen contracu should be negotiated long- term to achieve the lowest prices. The cost model shown in table 1 below assumes that a twenty year contract at fixes prices (adjusted for inflation only) could be negotiated. We note that the proposed new landfill for Orange County is designed as a fifty yeaz facility. All transfer station capital and operating costs, tipping fee, hauling costs and ancillary landfill operations costs could be paid for with tipping fees as the landfill operation is now. If Orange County meets the adopted goal of 619o waste reduction per capita by ,:
