A BIPARTISAN group of US Senators is urging the US Environmental Protection Agency (EPA) to approve higher percentages of ethanol blended gasoline for use in non-flex fuel vehicles.
The letter points to new innovation and investment in the renewable fuels industry that's pushing ethanol production to what's known as the 'blend wall'.
The Senators say that's already impacting the ethanol industry with respect to investment in new biorefineries and second-generation biofuels.
According to the letter, an interim blend between E10 and E15 is necessary to meet the new US renewable fuel targets and to keep the renewable fuels industry growing.
As second generation biofuels are developed and commercialised, the Senators stress the importance of supporting the steady expansion of markets for ethanol with a move to a higher percentage of ethanol blended gasoline in the near future.
The letter to EPA Administrator Lisa Jackson was signed by a group of prominent mid-western states' Senators.
