4C TRANSFER AND HAUL <br /> Transfer Station Costs <br /> The net annual owning and operating costs and eneray consumption of <br /> the two transfer station concepts developed in Chapter 3 are as follows : <br /> Annual Annual <br /> �� <br /> T e Energy Consumption <br /> Net Costs (IKMBTU) (1) <br /> Direct Dump <br /> Top-Loaded Trailers $410,000 2,941 <br /> Hydraulic Compaction <br /> Rear-Loaded Trailers with $448,000 3,986 <br /> Stationary Compactors <br /> Haul Cost <br /> Collection Fleet: <br /> The construction of the proposed transfer station will not eliminate <br /> collection vehicle haul costs. However, it significantly reduces <br /> haul times and therefore increases the productivity of each vehicle. <br /> With increased productivity, the number of vehicles required to <br /> collect the solid wastes generated is reduced. The makeup of the <br /> reduced collection fleet is as follows : <br /> Type Vehicles Sp ares Crew Size <br /> Rear-End Loaders 12 1 3 <br /> Rear-End Loaders 5 1 2 <br /> Front-End Loaders 5 1 2 <br /> Drop-Box Trucks 5 1 1 <br /> The shorter distance to the proposed transfer station permits collec- <br /> tion crews to spend a greater percentage of their time collecting <br /> solid waste and a smaller percentage hauling solid waste. The per- <br /> centage of time spent in the haul operation by the various collection <br /> - vehicles is as follows: <br /> Time Spent <br /> Type in Haul (2) <br /> Rear-end Loaders 7 <br /> Front-end Loaders 10 <br /> Drop-box Trucks 27 <br /> (1) <br /> MIBTU = Million BTU <br /> (2) See Appendix C for derivation. <br /> - 20 - <br />
