As part of the Clean Air Act and laid out Environmental Protection Agency regulations, fuel manufacturers are required to register their products and additives with the EPA before they can be produced, shipped and sold for use in motor vehicles. Therefore, in the case of E15 (gasoline with a 15 percent ethanol content) EPA approval must be granted before the process to produce and distribute it can begin.
Now, the EPA has granted first application approval for E15, so although we’ve still got a ways to go before it shows up at your local gas emporium, the ball has started rolling.
To help expedite the process of E15 availability, the Obama Administration has put in place a strategy to help filling station owners install some 10,000 blender pumps over the next five years.
Because E15 is not recommended for use in vehicles older than the 2001 model year as well as many small engine devices such as lawn mowers, snow blowers and some boats; pumps that dispense the new fuel will be clearly labeled to make customers aware of the 15 percent ethanol blend (running E15 in older vehicles and small engines can cause corrosion and damage to certain parts of the fuel system due to the types metals employed, notably aluminum).
Additionally, the Department of Energy and Department of Agriculture (via the Recovery Act and 2008 Farm Bill) are encouraging further development in the field of bio fuel technology by issuing grants, loans and loan guarantees to individuals and organizations actively involved in this area.
