Gasoline Dispensing Facilities (Stage 1)

Stage I Gasoline Vapor Recovery System

In the Stage I gasoline recovery system, the truck tank captures displaced vapors while filling underground storage tanks (USTs).  The truck returns the vapor to the bulk gasoline terminal for processing.  The Stage I gasoline vapor recovery system collects 96% of the vapors that would have otherwise been emitted to the atmosphere to form ground level ozone which negatively impacts air quality.
