The National Air Pollution Control Administration has asked airline officials to stop the dumping of jet fuel into the air after takeoff. This fuel seeps from the engines into holding tanks during stops. Such dumping is likely to increase air pollution problems in neighborhoods around airports.

Citing National Airport in Washington, D.C., John T. Middleton, NAPCA's Commissioner, said castoff jet fuel amounts to an estimated 110 tons a year, and such quantities ‘could have significant effects on the health and welfare of people who live and work near the airport.’
