Stage II Gasoline Vapor Recovery Regulations
Gasoline dispensing pump vapor control devices, commonly referred to as Stage II Vapor Recovery Control, are systems that control volatile organic compound (VOC) vapor releases during the refueling of motor vehicles. This process takes the vapors normally emitted directly into the atmosphere when pumping gas and recycles them back into the fuel storage tanks, preventing them from polluting the air. The Stage II system controls the release of VOC, benzene and toxics emitted from gasoline.
Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island and Vermont have regulations that require Stage II vapor recovery at certain gasoline stations depending on the amount of gasoline pumped at the facility and the facility's location. The map below shows the counties in New England where stage II vapor recovery controls are required to be installed.
