13 ~~ <br />3, Transfer Station Option to Shin Waste Out of Coun <br />Although we are not awaze of any transfer stations built solely to handle construction and <br />demolition wastes, it is possible to construct such a facility. We believe the cosu would be similaz <br />to those of a conventional transfer station. We have used cost estimates for the transfer station from <br />the WESTON study on out-of-county disposal options from July 1995 escalated for three yeazs at <br />39o per year. Those costs include equipment, building and utilities. No additional personnel would <br />be required since personnel now operating the construction and demolition waste landfill would be <br />employed. A range of costs is shown from using the privately owned landfill in Wake County at <br />$22 per ton tipping fee at a 35 mile distance to using the next nearest known facility, 70 miles away <br />aE $25 per ton tipping fee: More detail is shown in attachment 3. <br />Cost estimate: $897,500 for construction. Plus $50,000 for solid waste plan administrator <br />Tipping fee: $32.11 to $44.18 per ton including transportation, final disposal and transfer station <br />costs amortized over 10 years. <br />Pros and Cons of Transfer Station <br />Pros of Transfer Stations "~ <br />• Smaller land requirement than the landfill or landfill plus processing scenario <br />• Relatively simple operation, low potential for odors without putrescible wastes <br />Cons of Transfer Station <br />• Significant new capital costs to acquire land, construct and permit <br />• Assume all tipping fee revenues would have to cover costs of operation, leaving <br />no other revenues available for financing other measures. <br />• Waste reduction goals cannot be met under this scenario <br />Option 4 Manually-Oriented Waste Recv~clina Facility <br />This facility includes a covered tipping floor onto which construction and demolition wastes are <br />dumped. Recyclable wood and metals are separated primarily by hand-picking. Some mechanical <br />equipment is used to spread loads and remove large or bulky items. This approach differs from the <br />semi-automated facility described next in option S. This facility does not have the trammel screen <br />and conveyor belt with picking stations that are included in the more automated facility. There is <br />one less picker in this facility. and the building is smaller. The facility would consist of a 100' x <br />200' building under a roof with a grapple crane, .five pickers and a foreman. The pickers would <br />manually remove recyclable or reusable materials from the construction and demolition wastes. <br />Materials to be removed would be 5096 of clean wood and 5090 of clean metals delivered to <br />facility. Detailed costs are shown in attachment 4. <br />Estimated Cost: $1,080,000 _ <br />Annualized cost and cost per ton diverted: $464,000/5,100 tons = $90.98 <br />
