4 28 rural collection and a volume based system or collection ban in place, we assume an overall, a diversion rate of 26 pounds per household per month , double the 13 pounds per household per month now diverted . The urban rate is now about 32 pounds per household per month. That includes all existing and new materials. It does not distinguish between materials diverted at the curb or drop off sites. Service would remain biweekly. E. Multifamily recycling. This is a mature program operating since October, 1991, now with 165 sites in Carrboro and Chapel Hill. We assume that multifamily service will be provided at every dumpster site within the multifamily complexes instead of the approximately one-third of dumpster sites now with recycling carts. We estimated 500 total multifamily dumpsters throughout the County, based on municipal reports and on a rule of thumb of 25 units per site. The cost estimate we used was corroborated with the multifamily service provider. Any actual expansion would have to be negotiated. We assumed a 25% increase in materials now collected and additional collection of 25% of the new materials including office paper, mixed paper, gable top boxes and#5 and#7 plastic bottles. F. Drop-off sites and convenience centers While we do not show any increases in service levels in this sector, we assume that some of the increased recycling projected in each subsector will actually occur at the drop off sites. No additional tonnage is attributed to the sites since they are not an economic subsector. We expect there will be some reduction in solid waste tonnage disposed of at the convenience centers. G. Materials Recovery Facility. We do not operate such a facility nor is there a commingled materials recovery facility operating in the Triangle region now. We estimated the cost per ton to process materials at a materials recovery facility based on a six facility average including that at four private facilities operating around the nation, a quotation from a private MRF operator to operate a facility in Orange County based on our tonnage and the tip fee estimated by WESTON for their minimum diversion scenario . The WESTON tip fee estimate included materials revenues. The total new and old recycling tonnage for all programs operated by Orange Community Recycling was then considered as processed at the MRF and multiplied by the average MRF operating cost to derive a total processing cost. That.was added to the new system cost in columns two and three. Ill. Total Solid Waste System Costs and Diversion Rates A. The summary table includes the following: 1. Existing system costs of collecting and landfilling of solid waste plus collection costs for recyclables, landfill operation costs for mixed solid wastes. 2. New cost of additional waste prevention and recycling programs averaging WESTON's cost estimates and diversion rates for the minimum diversion system and staff estimates of system costs and diversion rates by subsector. We assume for this report that the MRF is privately bui!:, owned and operated but sited on publicly owned land.
