Buildings on sites that will be used for less than 10 years can be
temporary, mobile structures. If possible, structures or buildings shoul
be located on natural ground a sufficient distance from the landfill to
preclude hazard from subsurface LFG migration. A good rule of thumb is a
minimum distance of 1000 feet (310 meters) from the landfilling area.
However, a greater distance may be required if the subsurface soils are
highly permeable and upward migration of LFG to atmosphere through the
surface is impeded by vegetation or pavement. If this is impractical, th
design and location of all structures should consider gas movement and, i
located over refuse, the differential settlement caused by decomposing so
waste.
7.4.9 Aesthetics. Maintaining a satisfactory appearance at the landfill
an effective means of promoting good relations and ensuring user cooperat
in landfill operations. When clearing the area, trees and bushes can be
left at or transplanted to the perimeter of the site to provide screening
and buffering. The entrance and weigh station should be attractive, as
should other facilities. Completed areas should be landscaped as soon as
possible after completion.
7.4.10 Scales. Recording the weights of solid waste delivered to a site
can help regulate the landfill operation as well as the solid waste
collection system that serves it.
Scales range from simple, separate axle-loading scales to sophisticat
electronic scales that feature printed outputs. Usually a portable scale
is sufficient for small operations with a limited site life.
Alternatively, smaller sites may elect to use a portable scale once a
year for a week or so to record "typical" waste quantities.
The platform and scale should be compatible with the trucks and loads
that are routinely handled at the site. In most cases, a platform betwee
10 and 35 feet (3 to 11 meters) will be sufficient for collection vehicle
and one of 50 feet (15 meters) will handle most trucks with trailers. A
scale that records up to 35 tons (31 800 kilograms) should be adequate fo
most landfills.
7.4.11 Utilities. Larger landfills should have electrical, water,
communication, and sanitary services. Remote sites may have to extend
existing services or use acceptable substitutes. Portable chemical toile
can be used to avoid the high cost of extending sewer lines; potable wate
may be trucked in; and an electric generator may be used instead of havin
power lines run into the site.
Water should be available for drinking, dust control, washing mud fro
haul vehicles before entering the public road, employee sanitary faciliti
and fire control. A sewer line may be desirable, especially at large sit
for conveying leachate to the domestic wastewater treatment plant.
Telephone or radio communications may be necessary since accidents ca
occur that necessitate the ability to respond to calls for assistance.
