Custom Search Storage of bulky wastes shall include removing doors from
large household appliances and covering the items to reduce:
! any problem of an "attractive nuisance"
! accumulation of other waste and water in and around the bulky
items. Reusable waste containers emptied by hand must not exceed
75 lb when filled.  Collectors should not come in physical contact with the
waste. Procurement specifications for multiple containers shall
establish conformance with DoD Military Specifications MIL-R-2395C unless such
containers are unavailable or superior containers are desired.
Transfer and Transport
Types of Transfer Stations  There are several types of transfer station systems commonly
employed.  These are briefly described below:  Direct Dump to Container.  This is the most basic and simple
form of transfer system.  This system is employed when small volumes (100 yd3
or less) of solid wastes are handled.  Container volumes range from about 15
to 55 yd3.  Full containers are replaced with empty ones, and the full
container is transported to the disposal site by tilt-frame trucks. This type
of system is advantageous because of low capital costs and simple loading
methods.  However, because of the low solid waste densities (about 200 lb/yd3)
obtained, spare containers may be required to handle incoming waste during
peak periods.  Also, there are potential hazards associated with this method,
including leachate generation due to rainfall into the open box and the
possibility of someone falling into the container while unloading the solid
waste.  Dump into Trailer.  With this method, solid waste is dumped
from an elevated area into trailers instead of drop boxes.  It is more
commonly used than the drop box system.  Trailers are available to handle up
to and even over 130 yd3.  Open-top trailers are less expensive initially and
require less maintenance than the alternative compactor trailer types.
Disadvantages of trailer systems are the same as for the drop box systems
except haul costs are less because of the larger payload.  There are several
methods commonly employed to feed waste into transfer trailers, including:
! Direct Dump.  With this method, solid waste is dumped directly
into the trailer from the collection vehicle from an elevated
ramped area (see Figure 4-2-SA).
! Dump to Storage Pit.  For this system, solid waste collection
vehicles dump directly into a storage pit where the waste
materials are crushed by crawler tractors and then pushed over
