Gasoline and Vapors
EPA Low Sulfur Gasoline Information

California Air Resources Board, Vapor Recovery
The Board evaluates new and modified vapor recovery systems that "recycle" gasoline vapors generated while fueling vehicles.
Stage II Vapor Recovery Systems
A system designed to capture gasoline vapors that would otherwise escape into the atmosphere as vehicles are refueled.
Suspension of Enforcement
Systems are required for about 1,600 gasoline dispensing facilities in Allegheny, Armstrong, Beaver, Bucks, Butler, Chester, Delaware, Fayette, Montgomery, Philadelphia, Washington and Westmoreland Counties. Due to the diminishing emission reduction benefits of Stage II controls, the Department has issued two notices of the Suspension of Enforcement of the Stage II Vapor Recovery Requirements, one on August 18, 2012, and one on November 12, 2016.
