Ethanol Groups Push EPA to Consider Future E85 Use in New Vehicles

With a recent expansion of government programs to help E85 use expand across the country, ethanol industry groups this week asked the EPA to maintain and bolster an important factor used by the agency to incentivize E85 use.

The so-called 'F factor' is used by EPA to estimate the volume of E85 fuel expected to be consumed by flexible-fuel vehicles during the life of the vehicles.

The factor is the basis for a credit available to automakers for compliance with EPA's light-duty vehicle greenhouse gas program and corporate average fuel economy program. A higher F factor is an incentive for automakers to produce more FFVs.

In comments submitted to the EPA on Monday, the Renewable Fuels Association called on the agency provide a long-term "floor" and "more robust" E85 use factors for future model year vehicles.

"Based on our discussion with automakers, it is clear that manufacturers will hesitate to invest in certain technologies, like FFVs, unless there is some assurance that those vehicles technologies will help enable CAFE and GHG standard compliance over multiple model years," Kelly Davis, RFA vice president for regulatory affairs, said in comments.

"Fuel blenders and retailers also need multi-year certainty regarding the likely mix of light-duty vehicles so that they may appropriately direct their investments in wholesale and retail fuel infrastructure."

Davis said restoring a "more meaningful E85 usage factor" for FFV production would help to level the playing field that currently favors battery electric, plug-in hybrid electric, fuel cell and compressed natural gas vehicles.

"While we agree with EPA that automakers should be encouraged to produce vehicles that reduce petroleum consumption to improve energy security, save the U.S. money, and reduce climate change impacts, we believe incentives to stimulate the production of such vehicles should be constructed fairly and consistently," she said in comments.

As part of its comments, RFA submitted an analysis comparing the number of E85 stations listed on the association's crowd-sourced database to the number of E85 stations listed by the Alternative Fuels Data Center. The former lists just more than 5,000 E85 stations, while AFDC's database lists about 3,600. There are more than 22 million FFVs on U.S. roads.

EPA relies on the AFDC database to inform its projections of future E85 availability and station growth. RFA asked the agency to use the database to inform future analyses.

EPA previously released a draft determination in March 2013 and proposed an F factor of 0.20 for the 2016 model year. EPA's proposal assumed an FFV produced for that model year would use E85 approximately 20% of the time across its lifespan.

In October of 2014, EPA finalized an F factor of just 0.14, or 14%, for model years 2016-2018. The 0.14 F factor was carried over for model year 2019. Then on Aug. 20, 2020, the EPA extended the 0.14 F factor to model year 2020 and later vehicles.

"ACE supports an F factor of at least 0.20 for model year 2021 and later vehicles, and we encourage EPA to consider new, forward-looking data which indicate E85 use will significantly rise in the future," Brian Jennings, chief executive officer of the American Coalition for Ethanol, said in comments to the agency.

"Until such time EPA establishes a 0.20 or greater F factor, ACE strongly encourages the agency to maintain the 0.14 F factor, so the value does not default to zero."

Maintaining the current factor is important because there are more stations that sell E85 than originally assumed by EPA and the U.S. Department of Energy, the number of stations will "significantly" increase thanks to nearly half a billion dollars of infrastructure investment, Jennings said, and volumes of E85 will rise as station owners utilize carbon credit and renewable identification number value to price the fuel at retail."

Growth Energy Senior Vice President of Regulatory Affairs Chris Bliley, said in comments the agency has to account for a growing E85 market.

"Recent trends in government and private investment in biofuels infrastructure and updated data on E85 availability all lead to growth in higher biofuel blends," he said. "EPA should seize on that data to provide appropriate, immediate credit to automakers to continue to produce flex-fuel vehicles to run on these higher biofuel blends."

In Growth Energy's written comments, the group provided a detailed analysis on the benefits of an updated F factor, noting any upward revision should take immediate effect so it continues to accelerate automaker investment and innovation.
