a) Aircraft Machine and Paint Shops. Aircraft
machine and paint shop wastes include many types of lubricating
and cutting oils, hydraulic fluids, paints, paint strippers,
solvents, degreasers, washdown waters, and plating wastes. Do
not discharge these wastes to a building drain system. Collect
in separate systems and route to oily or industrial wastewater
treatment systems. Check the compatibility of wastewater
mixtures and the hazardous waste nature of the mixture.
b) Fuel Transfer Operations. Spills may occur during
fuel transfer operations. If possible, use dry absorbents to
pick up oil and dispose of them as solid waste material. Check
flash point of the spent material for possible hazardous waste
characteristics.
c) Runway Operations. At airports subjected to cold
weather, deicing fluids such as ethylene glycol are used to keep
runways from icing over. Deicing fluids are generally washed
off by rainfall or snowmelt into runway storm sewers.
3.3
Discharge Criteria. Oily wastes must be treated to
comply with Federal, state, and local regulations. The effluent
from the oily waste treatment plant may be discharged to either
navigable waters or to a POTW. The NPDES permit determines the
effluent quality requirements for discharge to navigable waters.
Effluent quality requirements for discharge to POTWs are
determined by local and municipal authorities and, therefore,
may vary from place to place. The effluent quality requirements
most typically encountered, and for which treatment system
design criteria are developed herein, are as follows:
