An official website of the United States government.

Due to a lapse in appropriations, EPA websites will not be regularly updated. In the event of an environmental emergency imminently threatening the safety of human life or where necessary to protect certain property, the EPA website will be updated with appropriate information. Please note that all information on the EPA website may not be up to date, and transactions and inquiries submitted to the EPA website may not be processed or responded to until appropriations are enacted.

We've made some changes to EPA.gov. If the information you are looking for is not here, you may be able to find it on the EPA Web Archive or the January 19, 2017 Web Snapshot.

Gasoline Standards

State Gasoline Standards

The federal Clean Air Act establishes national fuel emission standards, but also allows states to adopt unique fuel programs to meet local air quality needs. The combination of federal and state fuel programs is intended to balance the importance of standard fuel quality across the country with the need for sufficient flexibility to address specific air quality issues at the state or local level.
