Sanitary Landfill Design and Operation  General.  Sanitary landfilling is an engineered solid waste
disposal process which minimizes the environmental hazards and nuisances of
land disposal.  Solid waste is delivered to a carefully selected and prepared
site, deposited into a trench or controlled area, compacted, and covered with
soil or other material daily.  Landfills must conform to EPA and/or state
requirements.  Potential regulations at the state and federal level would
require double liners with leachate collection and groundwater monitoring for
all new landfills.  Sanitary landfills have advantages not common to most other
methods of refuse disposal:  they do not require large operating crews; they
can receive all categories of solid wastes, except hazardous waste; they can
accommodate large fluctuations in the daily accumulation of refuse without
additional personnel or equipment; and they provide reasonable control of
vectors and pollution.  The sanitary landfill is capable of accepting a wide variety
of solid waste types.  Nearly all rubbish, garbage, trash, ashes, solid
organic waste, and miscellaneous solids may be disposed of safely. Most
domestic-type solid waste can be disposed of without presorting, or in
combination with the following solid waste reduction techniques:
incineration, baling, compacting, or shredding.  Certain waste products are not appropriate for sanitary
landfill operations.  These include hazardous waste; toxic substances;
liquids; untreated infectious waste; and volatile, explosive, or flammable
wastes.  Measures shall be taken to ensure that these solid waste products are
not delivered to the landfill site.  Plans for separation and removal of
accidental deliveries shall be kept current.  Sanitary Landfill Design.  The objectives of a landfill
design are to (1) ensure compliance with pertinent regulatory guidelines/
requirements; (2) provide adequate present and long-term protection of the
environment; (3) achieve cost-efficient utilization of site manpower,
equipment, volume, and soil; and (4) direct and guide operators toward proper
construction and operation of the landfill.  This section provides guidance on
design considerations for a sanitary landfill to achieve these objectives.  Regulations and Permits.  Many regulatory and approving
agencies require permits before a landfill can be constructed or operated.  A
conceptual landfill design is generally an integral part of the application
