Gasoline and Vapors

EPA Low Sulfur Gasoline Information
New standards have been developed to reduce the sulfur content of gasoline by up to 90 percent and therefore reduce harmful air pollution.

Clean Gasoline Program for Southwest Pennsylvania
Seven counties are provided with gasoline with lower evaporability in the summer to reduce ozone pollution. In 2017 the Environmental Quality Board proposed regulations that would effectively repeal those requirements once EPA approves a demonstration by the department that the rule repeal would not affect the continued attainment or maintenance of a National Ambient Air Quality Standard or any other applicable requirement of the Clean Air Act.  In March 2018, the Department opened public comment on a revision to the State implementation plan that provides to EPA the demonstration required by the Clean Air Act and requests that the EPA remove the seven county summertime gasoline rule from the plan.  

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.
