E15 is here.

In June 2012, the U.S. Environmental Protection Agency cleared the final hurdle on E15 for consumer use. By raising the "blend wall" in gasoline from E10 to E15, Growth Energy is accelerating the use of renewable fuel, increasing energy security, creating U.S. jobs, and improving the environment by displacing conventional gasoline with low-carbon ethanol.


In March 2009, Growth Energy filed its Green Jobs Waiver to the U.S. Environmental Protection Agency seeking approval to blend up to 15 percent ethanol in gasoline, from the current cap of 10 percent ethanol. By raising the “blend wall” from E10 to E15, the Growth Energy Green Jobs Waiver would accelerate the use of renewable fuel, increase energy security, create U.S. jobs, and improve the environment by displacing conventional gasoline with low-carbon ethanol.

The EPA has issued its final decision to allow E15 in cars 2001 and newer. This decision will apply to 239 million cars on the road today — meaning that E15 will now be allowed in all the autos manufactured in the last decade (equal to more than 80 percent of all the vehicles on the road today).

Now that tests are complete, EPA’s approval of E15 can and should be extended to older vehicles to make real progress in reducing America’s dependence on foreign oil. Growth Energy is working with the Department of Energy to conclude testing on vehicles manufactured prior to 2001.

A full move to E15 creates a bigger market for American ethanol that could help create as many as 136,000 new jobs in the United States and eliminate as much as 8 million metric tons of GHG emissions from the air in a year — the equivalent of taking 1.35 million vehicles off the road. Increasing the domestic, renewable fuel supply would also displace some of the 7 billion gallons of oil that is imported every day into the United States from countries such as Venezuela, Saudi Arabia and Nigeria.

Original Documents

On March 6, 2009, Growth Energy officially filed a waiver to the Clean Air Act requesting approval for use of an ethanol-gasoline blend containing up to 15 percent ethanol by volume. Read the cover letter to EPA (PDF) and waiver application (PDF). 

Growth Energy's comments on the waiver filed with EPA (PDF)

On Nov. 30, 2009, the EPA responded (PDF) to our waiver request with notification that testing on vehicle durability was not complete and expected data from those tests to be available by mid-June, 2010. Listen to press conference audio on this decision to delay the waiver grant.

On June 17, 2010, Growth Energy sent a letter to President Obama (PDF) urging him to take whatever steps are necessary to accelerate the Department of Energy testing required for the Green Jobs Waiver application. Listen to press conference audio about the letter and EPA's decision to delay the waiver grant again.

On October, 13, 2010, EPA responded (PDF) to Growth Energy with a partial grant of the Green Jobs Waiver. Read their press release at EPA.gov.

EPA responded to Growth Energy's waiver application on Nov. 4 2010 in the Federal Register. Read the decision of the Administrator as printed in the Federal Register (PDF).

EPA issued the second part of the waiver on January 21, 2011. The text of that waiver can be read here.

On June 28, 2011, EPA released its label for fuel pumps dispensing E15 and issued its final label rule in the Federal Register on July 25, 2011.

On April 2, 2012, EPA approved the first applications for registering ethanol for use in making E15. For more information, see the E15 Registration page and the Registration and Health Effects Testing page.

On February 17, 2012, EPA released an evaluation of information submitted by Growth Energy and the Renewable Fuels Association for satisfying the emissions and health effects data requirements for registration of E15. The Evaluation Document concludes that the submission would be sufficient to satisfy those requirements. Fuel and fuel additive manufacturers who wish to register E15 may choose to rely on the submission for completing their applications.

On June 15, 2012, EPA approved the first plans for satisfying the misfueling mitigation conditions of the E15 partial waivers.

In 2015, the USDA provided more than $100 million in partnership with private and state funding to provide nearly 5000 pumps for higher ethanol blends in 21 states.

Today, E15 is being offered by more than 355 retail stations in more than 26 states including major retailers such as Sheetz, Kum & Go, Murphy USA, and Minnoco giving consumers a low-cost, higher octane fuel choice at the pump.
