Stage I & II Testing

Gasoline Dispensing Facilities

 

Gasoline belongs to a category of chemicals known as volatile organic compounds (VOC), which are the main precursor of ozone formation. As part of a strategy to reduce ground level ozone, Stage I & II  permits may be necessary in your area.

 

Wholesale, retail, and commercial distribution points for gasoline are required to have Stage I and systems to reduce VOC’s released into the surrounding environment by 95%.

 

When a tanker truck delivers gasoline to a station, the new fuel entering the underground tank forces accumulated gasoline vapors out of the tank into the air. With a properly-functioning Stage I vapor recovery system, these vapors are returned to the tanker truck through a vapor recovery line, instead of into the air.

 

Stage II vapor recovery systems recover vapors that would escape while refueling a vehicle at the pump. Specially-designed nozzles and hoses prevent the escape of vapors as gasoline is pumped into the vehicle by returning vapors to the underground storage tank or an incinerator.
