A numerical rating system, as illustrated in Table 9, can help rank
the sites in order of preference. Note that a rating system can provide
reasonable approximation of the best site location, but engineering
judgement will still be essential in deciding on the final site location.

Transfer Station Costs.
Costs to be considered are as follows:
a)
Capital Costs.
1)
Design engineering and environmental impact statement (EIS)
preparation.
2)
Legal costs (permitting, etc.).
3)
Land acquisition.
4)
Site improvement overhead (SIOH).
5)
Site preparation.
6)
Concrete structures, foundations, and buildings.
7)
Security system.
8)
Landscaping.
9)
Transfer bins, tractors, and trailers.
10)
Wheel or track loader.
11)
Equipment for leveling and tamping solid waste in transfer
trailers.
b)
Annual Costs.
1)
Transfer bins, trailers, and tractors
(a) Operations and Maintenance (O & M).
(b) Taxes, licenses, and insurance.
2)
Labor.
3)
Transfer station O & M.
4)
Building amortization (as applicable).
5)
Transfer station equipment O & M (as applicable).
Once these costs are developed, a comparison with direct haul versus
transfer vehicle can be made and the most viable system selected. Figure
presents an illustration of direct haul versus transfer haul cost compari
curves.
