table. This can performed with synthetic liners or clays with low permeability (10 7
cm/sec percolation rates).
(b) The location of the landfill in relation to inhabited buildings is usually
determined by local ordinances, economic considerations, etc. Nonetheless, 750 feet
away from these buildings can be used as a rough guide.
(c) The hauling distance should be kept (roughly) to a maximum of 3
miles in order to reduce hauling costs. All-weather access roads should be provided if
there is no established road already present.
(d) Provision to prevent run-on and run-off of storm water (berms [ledge
at top/ bottom of slope] and drainage gullies) must be implemented to prevent erosion
and protect the surrounding environment.
(e) In cold areas where the frost line extends 2 feet below the surface of
the earth, landfills should not be constructed.
(4) Surveillance by medical personnel (preventive medicine personnel) is
necessary to ensure that spillage of wastes are kept to a minimum and coverage done
as frequently (at least daily) as necessary to prevent fly breeding and rat infestation.
Frequent covering also reduces the inflow of rainfall or run-off into the fill, thus
preventing the pollution of nearby ground or surface waters by leaching at the bottom.
(5) The landfill should be surrounded by 8-foot-high security fences to retain
blown paper and other lightweight material and to prevent unauthorized access. When
the trench method is used, the trench should be sealed twice weekly.
c. Incineration. Incineration is a method used at some installations for disposal
of garbage and combustible rubbish. Compliance with air pollution regulations requires
costly control devices on incinerators. Therefore, they are used primarily where land
area is insufficient for developing sanitary fills and where incineration is the best method
for disposal of regulated medical waste. Incineration will be dealt with in greater detail
in Section III of this lesson.
1-10. RECYCLING (SALVAGE)
a. The recycling program is administered by the installation DRMO. Recycling
includes anything which has market value and upon which contractors are willing to
submit bids. Examples of recycling commodities are hog food garbage, grease, bones,
wastepaper and cardboard, bottles, tin cans, waste motor oil (crankcase draining), tires,
batteries, scrap lubber, and innumerable other items. The DRMO decides when
materials will be segregated and placed for collection as recycling and when they will be
placed as refuse. The DRMO arranges for the issuance of appropriate regulations by
the installation headquarters.
