1.5 WASTE OIL SOURCES.  Large quantities of waste oils are continuously
generated by Navy and Marine Corps ships/shore activities and aircraft
facilities.  The waste oils generated from these sources are predominantly
those recovered from bilge and ballast water. These oils are composed
primarily of the fuel used by the particular ship. Lubricating oils and
similar materials from vehicles and ships rank second highest in quantity.
Contaminated high flashpoint fuels, such as JP-5, diesel, and kerosene,
rank third highest in quantities generated. Solvents and low flashpoint
fuels are generated least.  From the standpoint of utilization as a
supplemental boiler fuel, these waste oils may be grouped into three
categories:
Light waste oils - oils recovered from ship bilge/ballast water and
contaminated high flashpoint fuels; estimated to be 87 percent of
the total waste oils generated throughout the Navy.
Heavy waste oils - engine drainings, shop facility wastes, and tank
cleanings; estimated to be 9 percent of the total waste oils
generated throughout the Navy.
Low flashpoint materials - most solvents and contaminated low
flashpoint fuels; estimated to be 4 percent of the total waste oils
generated throughout the Navy.
It should be noted that the percentages are Navywide estimates only, and
may vary considerably for specific sites.  Both light and heavy waste oils
are suitable for boiler fuels, while low flashpoint materials are
undesirable as boiler fuel for safety and environmental reasons.  Of all
the waste oil the Navy generates, 96 percent is therefore considered to be
a desirable supplemental source of energy.  These waste oils are of higher
quality than the No. 6 fuel oil frequently used in boilers.
1.6 NAVY WASTE OIL GENERATION/DISPOSITION.  Over a 4-year period (1980-84)
NCEL has conducted a survey of waste oil generation and disposition by Navy
and Marine Corps shore activities.  The most recent results are given in
Appendix B.
The Navy generates roughly the equivalent of 2 million MBtu of waste
oil annually.  Only 15 percent of this is presently burned as a boiler
fuel; the remaining 85 percent is disposed of in several ways: (1) local
firefighting training; (2) Naval Supply Systems Command (NAVSUP), Defense
Logistics Agency (DLA), or Defense Property Disposal Office (DPDO) handle
resale; (3) sold or given to haulers; (4) paid to have hauled away; or
(5) stored.  This illustrates the potential for more productive use of
significant quantities of waste oil.
