where the accumulation of sludge in substantial quantities is
likely to occur on a regular basis. Sources of such sludge
are a ballast water treatment system, a contaminated fuel
recovery system, or frequent cleaning of shore or ships'
tanks. If routine cleaning of clean product storage tanks
occurs on an irregular basis, sludge removal systems are not
a) Where possible, provide pumps, tanks, and piping
to return sludge containing recoverable oil to the
contaminated oil recovery system. If this is not possible,
consider transferring the sludge to a refinery or waste oil
treatment facility. For additional details, refer to
MIL-HDBK-1005/8 or for Army projects, Corps TM 5-814-3.
b) Provide a tank or tanks with transfer pump(s) for
pumpable sludges that are unreclaimable. Include piping for
receiving sludge and for mixing other low viscosity waste oils
for thinning as required. Ensure that tanks are dike-enclosed
and have cone bottoms.
c) Provide tank heating where climate conditions
d) Coordinate sludge disposal method and design with
facility environmental office.
e) Enclose the sludge disposal facility with a
security fence to prevent unauthorized entry. Do not use this
facility for disposal of sand, gravel, rust scale, or other
solid nonpumpable matter found on tank bottoms. For further
discussion of disposal methods, refer to NAVFAC MO-230.
