7.8 Management. The manager of a landfill site has the following
a) Assure that operations are in conformance with design plans and
b) Strive to make daily operations run smoothly.
c) Maintain site security.
d) Purchase equipment and assure appropriate maintenance.
e) Personnel training and safety.
f) Personnel and user relations.
7.9 Costs. It is important to keep cost records. Figures 27 through 29
illustrate cost accounting forms for land, equipment, and other facilitie
The figures are taken from SCS Engineers, Sanitary Landfill Design and
Operations Practices. Some of the columns may therefore not be applicabl
to the Navy.
Sanitary landfill costs can be categorized into capital costs and
7.9.1 Capital Costs. Capital costs are meant to include all initial
expenses required prior to the startup of operation. Capital costs
a) Land acquisition.
b) Planning and design.
c) Site preparation (i.e., clearing and grubbing, road
construction, surface water and leachate controls, soil stockpiles,
d) Facilities (i.e., offices, personnel shelters, garages, etc.).
e) Equipment purchase. The cost of equipment may be the greatest
portion of initial expenditures. The landfill equipment market is
competitive, but rough approximations of costs can be obtained from a loc
equipment supplier. As a rule of thumb, a piece of landfill equipment us
for excavating, spreading, and compacting has a useful life of 5 years or
10,000 operating hours, whichever comes first. Due to the high cost of
equipment, however, it may be prudent to overhaul the machine at the end
5 years or 10,000 operating hours, and then replace the machine after
another 2 to 3 years, or 5,000 to 7,000 hours.
7.9.2 Operating Costs. Operating costs are expenses incurred during the
ongoing operation of the landfill.
It is common to compute operating costs as cost per unit of solid was
received. This is usually expressed in dollars per ton, or occasionally
dollars per cubic yard. Figure 30 is an example of an accounting form us
to record operating costs. Using the depreciation schedule, capital and
operating costs are combined and expressed as total costs per unit of sol
waste disposed. A more complete discussion of landfill costs is presente
in Booz, Allen, and Hamilton, Cost Estimating Handbook for Transfer,
Shredding, and Sanitary Landfilling of Solid Waste.
