Existing Controls

EPA issued standards in 1973 that called for a gradual phase down 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.

New RSF standards

The Renewable Fuel Standard (RFS) program was created under the Energy Policy Act (EPAct) of 2005, and established the first renewable fuel volume mandate in the United States. As required under EPAct, the original RFS program (RFS1) required 7.5 billion gallons of renewable fuel to be blended into gasoline by 2012. The new Renewable Fuel Standard (RFS2) goes into effect July 1, 2010 and will apply to all gasoline and diesel produced or imported in 2010. RFS2 lays the foundation for achieving significant reductions of greenhouse gas emissions from the use of renewable fuels. All renewable fuel producers must re-register under RFS2 due to the additional information required.

A variety of EPA Fuels Programs require submission of forms by manufacturers and importers of gasoline, diesel fuel (including biodiesel) and fuel additives. Some forms are used for registration of companies, facilities and products while others are used for compliance reporting.
