41 Orange County, NC Financial Plan and Rate Study for Solid Waste Enterprise Fund times and increase operational efficiency. In addition, efficiencies can be gained on the back end of the process as increased waste storage capacity is gained temporarily in the pushwalls or surge pit during times of peak waste acceptance. This increases the waste density (and therefore payloads) of material hauled by the trailers and reduces the number of transfer trailers needed to be purchased during the capital phase of transfer station construction. • As outlined in the Scenario 6 input parameters, the proposed transfer station should be sized to handle 250 tons per day to allow both seasonal peaks and long -term increases in waste quantities. SCS believes that typical costs for this size of station should range from 4 to $7 million, including site acquisition, design, permitting, and construction oversight. • The proposed transfer station would include a recyclable material receiving bay to serve as the receiving, handling, and transfer point for collected recyclable material delivered by Orange County and its contractors. This function is currently served at the Orange County Landfill at 1514 Eubanks Road. Additional design considerations would be needed to be made in order to accommodate the separate collection bay and additional traffic entailed by a dual - purpose facility. Typical annual operating costs of the proposed transfer station (ranging from 5 to $10 per ton) would include labor, building and site maintenance, utilities, rolling stock fuel, equipment O &M replacement, supplies, and other similar costs, which are required to manage the received waste at the station and transport it using transfer trailers to the ultimate disposal location. These costs are limited to the actual on -site operations and do not include the hauling operation costs, which typically range $10 to $20 per ton depending on haul distance. The County could consider other potential revenue options from ownership of its own transfer station. Revenue from a surcharge on the transfer station tipping fee and /or a flat host fee surcharge could supplement the Fund's revenue or be diverted into the R &E fund in order to help offset construction/maintenance costs, operations costs, etc. A transfer station feasibility study should be conducted in order to assess the costs and benefits of implementing another revenue - producing disposal point within the County to replace the closed Orange County Landfill. 3.2.2 Transfer Station Implementation Quantitative Analysis SCS performed a basic financial analysis of the cost - benefit considerations of implementing a revenue - generating transfer station within Orange County. Capital costs of a newly - constructed co- located or combined transfer station and materials recovery facility (MRF) are estimated and presented in Hypothetical Transfer Station Net Revenue Estimate in Appendix G. Results of this analysis seem to indicate that key variables will affect the financial feasibility of implementing a transfer station with participation by Orange County, the Towns, and private collectors. Modeled cash flows from the hypothetical operation of a County -owned transfer station are shown in the context of the County budget in Scenario 6. The results of this analysis indicate the annual average expenses of the transfer station (including capital costs, operating costs, hauling costs, and disposal tipping fees over a 20 -year reference period is $3.6 Million per year. Annual average revenues over the same period are $3.8 Million per year. Note that the analysis 28
