In accordance with the federal Clean Air Act (CAA), the US Environmental Protection Agency (EPA) establishes fuel quality standards to help protect public health and the environment from harmful gaseous and particulate emissions from motor vehicles and engines. 

EPA issued standards in 1973 which called for a gradual phasedown of lead to reduce the health risks from lead emissions from gasoline. Beginning in 1989, EPA required gasoline to meet volatility standards (in two phases) to decrease evaporative emissions of gasoline in the summer months. Upon passage of the 1990 CAA amendments, EPA began monitoring the winter oxygenated fuels program implemented by the states to help control emissions of carbon monoxide. It also established the reformulated gasoline (RFG) program which is designed to reduce emissions of smog-forming and toxic pollutants. EPA also set requirements for gasoline to be treated with detergents and deposit control additives. More recently, EPA has set standards for low sulfur gasoline and low sulfur diesel which will help ensure the effectiveness of low emission-control technologies in vehicles and reduce harmful air pollution.

Mobile Source Air Toxic (MSAT) Emissions home page Contains regulations, reports, and guidances regarding air toxic emissions from motor vehicles. On March 29, 2001, EPA promulgated new regulations setting standards for gasoline toxics performance levels. These MSAT regulations require each refinery and importer to meet refinery/importer-specific compliance baselines for conventional and reformulated gasolines. To determine these compliance baselines, refineries and importers need to apply to EPA for a toxics baseline.
