Ten years ago the amount of gasoline vapor lost during refueling operations was only a small fraction of the total hydrocarbons poured into our atmosphere. But as the control of other sources has improved, emissions from vehicle refueling have become a much larger percentage of total emissions. This has led EPA and local enforcement agencies to include control of refueling emissions in their implementation plans. The results of some research are discussed, including: (1) systems for minimizing the emissions; (2) test procedures for measuring the emissions at service stations; and (3) regression equations for predicting the amount of the emission under a wide range of conditions. Two methods of emission control are being developed for use at service stations: the vapor balance system and the vacuum assist system with secondary recovery. With both systems, two hoses are attached to the fuel dispensing nozzle. One hose carries the dispensing fuel to the vehicle tank, and the other routes the gasoline vapor back to the underground storage tank.
