EPA looking into the safety of E20 and  E30,  Those little stickers announcing  that the fuel you're about to put into your tank contains up to 10 percent  ethanol are getting pretty ubiquitous, aren't they? But pumps that can dispense  E20 or E30 are less common, and they may never take off because the EPA is  worried that the higher ethanol content in the fuel can damage cars that are not  equipped to deal with the biofuel. Since these "blender pumps" operate the same  way as standard gasoline pumps and customers might inadvertently put them in  non-E85 ready vehicles, the EPA is stepping in to stop them from operating in  some areas, like South Dakota. The EPA is researching whether 20 or 30 percent  ethanol-blended gasoline meets Clear Air Act standards and how it affects  engines.
Rick  Pigors, manager at the Farmers Union Co-op, told the Aberdeen News  that if the EPA shuts the E30 pump down, he expects people will put standard  gasoline and E85  into their tanks to arrive at a mix of about E30. It's not precise, but it's  what his customers want.
