EPA regulations require that each manufacturer or importer of gasoline, diesel fuel, or a fuel additive have its product registered prior to its introduction into commerce. In some cases, EPA requires testing of these fuels and fuel additives for possible health effects. EPA also requires that gasoline contain a certified detergent in order to reduce emissions. EPA issued standards in 1973 that called for a gradual phase-down of lead to reduce the health risks from lead emissions from gasoline, culminating in the Clean Air Act Amendments of 1990 and EPA regulations banning lead in motor vehicle gasoline after 1995.
Beginning in 1989, EPA required gasoline to meet volatility standards to decrease evaporative emissions of gasoline in the summer months when ozone levels are typically at their highest. In the early 1990s, EPA began monitoring the winter oxygenated fuels program implemented by the states to help control emissions of carbon monoxide during the winter months, and established the reformulated gasoline (RFG) program to reduce emissions of smog-forming and toxic pollutants.
More recently, EPA promulgated new regulations setting standards for gasoline toxics performance levels and standards for low sulfur gasoline to reduce harmful air pollution and help ensure the effectiveness of advanced emission control technologies in vehicles. Read more basic information.
