Patronize gas stations that have vapor-recovery nozzles (those black, accordion-looking plastic devices attached to the nozzle) whenever you can. They capture the gasoline vapors that escape from automobile tanks when they are being refueled. The vapors are returned to the underground gasoline storage tank through special hoses and pipes. The underground tank is also equipped with a vapor recovery system that works hand-in-hand with the vapor controls on the gasoline pump. This two-step vapor recovery process ensures efficient capture of gasoline vapors. [6]
