In addition, the EPA indicated it will require stations that sell E15 to also have a pump with a dedicated E10 hose for use by motorcycles and other vehicles the EPA hasn’t approved for E15 use.
Much ado about nothing. The EPA is not requiring anybody to sell E15. They are just saying that "if you do", you must also continue to sell E10 for vehicles that should not use E15. Because of this requirement, it seems unlikely that anybody will choose to sell E15.
in CO, they want to start selling it soon. There are warnings on some of my local gas stations that the change could be coming. Perhaps with the change to the law it will be delayed a bit.
