The Environmental Protection Agency (EPA) is seeking public comments on a waiver application to increase the amount of ethanol that can be blended into a gallon of gasoline to up to 15 volume percent (E15).
Since 1978, the limit has been at 10 volume percent ethanol (E10) for conventional (non flex-fuel) vehicles. The application for a waiver came from Growth Energy and 54 ethanol manufacturers and was submitted March 6, 2009. Current statute calls for EPA to make a decision within 270 days of receipt, which is December 1, 2009, EPA said in its information.
More information on the E15 request is posted online at epa.gov.
