(primarily phenols). Paint booth sludge is also generated
intermittently when booths are cleaned. This sludge should be
evaluated for its hazardous waste nature by the EP toxicity
test. Some reduction in sludge volume can be achieved on drying
beds if proper climatic conditions exist. This reduces the cost
of ultimate sludge disposal.

Treatment System. The wastewater can be pretreated
onsite for phenol removal using the peroxide oxidation scheme
shown in Figure 5. Since wastewater volumes are small, batch
reactor tankage and onsite chemical storage requirements are
small. The effluent can be pumped to a central treatment
facility for removal of cyanide, hexavalent chrome, and other
metals. Alternatively, since volumes are small, they could be
hauled by a truck and stored at the central facility for
subsequent treatment. Because of the characteristics of paint
stripping wastes, limited or no onsite pretreatment is the
preferred method of waste handling. Treatment should be
conducted at a central facility.

Miscellaneous Shops
2.6.10.1 Operation. Naval installations include a variety of
miscellaneous operations. These include machining, parts
cleaning and overhaul, boiler operations, and vehicle and engine
repair.
2.6.10.2 Waste Characteristics. Typically, the wastes from
miscellaneous shop operations are low volume continuous
discharges or periodic batch dumps. The materials generally
included in the waste discharge are oily or of some
petrochemical base (for example, degreasing operations,
machining oils, cleaning solutions, and solvents).
2.6.10.3 Treatment System. Most waste from miscellaneous shop
operations can be handled in conjunction with other wastes
previously described in paragraphs 2.6.6 through 2.6.9.
Substitute chemicals or procedures should also be considered to
minimize troublesome wastes from miscellaneous shops. For
example, use of dry cleaning methods rather than wet cleaning
procedures as an option.
