and aesthetic consideration. The process of site selection shall involve
specialists from military, local, state, and federal agencies as appropriate.
220.127.116.11 Site characteristics. Various sites on an installation may
be available for sanitary landfill operations. These sites shall be screened
by the facilities engineer to determine which is the most advantageous, using
various site characteristics.
Land availability. Installation planning documents shall be
consulted in order to screen the sites. Also, legal considerations,
including the investigation of legal burdens, title restrictions, and
other possible jurisdictional blocks to the use of various sites for
landfill operations, shall be reviewed. Land area requirements vary
significantly with the type of landfill operation and characteristics
of land, compaction, and volume of waste generated by the
installation. Figure 4-2-6A provides estimates of volume of
compacted solid waste.
Cover material availability. Consider the availability and
suitability of cover materials. Most well-graded soils are suitable
for daily cover, but not for intermediate or final cover and should
exist at the site or be immediately available to the site. The
quantity of cover material will vary with the design characteristics
of the site. Typical waste:cover ratios of 4:1 to 2:1 are used.
Proximity. Landfill siting shall constitute a balance between
adequate distance from housing and work areas and economical hauling
distances. The landfill shall be sited at least 750 ft from
inhabited buildings and so that prevailing winds are away from living
areas, where practical. Also, landfills must not be sited within
10,000 ft of any point of any airfield servicing jet aircraft or
within 5000 ft of an airfield servicing only piston aircraft.
Roads. Sites shall be accessible to appropriate vehicles by all-
weather roads leading from the public road system.
Underground structures. Sites traversed by pipelines or conduits for
sewage, stormwater, etc., shall be rejected unless the relocation or
protection of the pipelines or conduits is feasible. These pipelines
may serve as pathways for gas and leachate. Plans for maintenance
and repair of protected pipelines must be developed.
Landfills cannot be sited within the 100-year flood
18.104.22.168 Topography. Specialists shall evaluate alternative sites
from the viewpoint of pollution hazards and possible environmental
degradation. Military agencies and laboratories such as the Facilities Housing
Support Agency, U.S. Army Construction Engineering Research Laboratory, Naval
Civil Engineering Laboratory, Naval Energy and Environmental Support Activity,
U.S. Army Waterways Experiment Station, U.S. Army Environmental Hygiene
Agency, Air Force Engineering and Services Center, and others can provide
additional technical guidance in these areas.
