New Ethanol Mandate to Breach 10% 'Blend Wall' Satisfies Nobody - Except EPA

new ethanol mandate to breach 10 8216 blend wall satisfies nobody except epa

Serendipitously, Sajeev Mehta’s post about the possible damage to older cars from gasoline-ethanol blends went up just a few days after the U.S. Environmental Protection Agency proposed a new mandate to mix another 700 million gallons of biofuels — including 300 million gallons of corn-based ethanol — into the country’s fuel supply.

The objective of the new mandate: hit a 18.8 billion gallon 2017 target for biofuels.

The move has both critics and supporters of ethanol unhappy.

Corn farmers and ethanol producers* point to the fact that the new 2017 target is still short of what Congress stipulated in a 2007 amendment to the 2005 Renewable Fuels Standard (RFS).

The EPA used its authority, written into that law, to temporarily waive the standard.

The Renewable Fuels Association said in a statement, “For months, EPA has been saying it plans to put the program ‘back on track.’ Today’s proposal fails to do that. The agency continues to cater to the oil industry by relying upon an illegal interpretation of its waiver authority and concern over a blend wall that the oil industry itself is creating.”

For its part, the oil industry isn’t pleased either. Critics of ethanol as a fuel say the RFS predates the significant increases in oil and natural gas production due to horizontal drilling and fracking, and that the standard is simply no longer needed because of abundant fossil fuel supplies.

The American Petroleum Institute said, “Consumers’ interest should come ahead of ethanol interests. EPA is pushing consumers to use high ethanol blends they don’t want and that are not compatible with most cars on the road today. The administration is potentially putting the safety of American consumers, their vehicles and our economy at risk.”

Chet Thompson, president of the American Fuel & Petrochemicals Manufacturers, issued a statement saying, “While we support the Environmental Protection Agency’s (EPA) continuing use of its statutory waiver authority to reduce the unrealistic mandated biofuel volumes for 2017, the proposed volumes still go beyond marketplace realities. EPA’s proposal threatens to force consumers to use more biofuel than vehicles, engines and fueling infrastructure can handle.”

Those claims about putting our vehicles at risk and blending more biofuel than vehicles can handle is based on the so-called “blend wall” of 10 percent that critics say will damage car engines. Isaac Orr, of the Heartland Institute, a free-market think tank, says the biofuel percentage will rise to 10.44 percent under the new rules.

As Sajeev pointed out, however, the damage to cars from current ethanol blends appears to be tolerably minimal, and not worth the additional cost of higher octane fuels that aren’t blended with alcohol. I’m not sure that a fraction of a percent is going to make a big difference with the automotive fleet, much of which is flexfuel capable, but there are millions of gasoline engines that could be more negatively affected. Small gasoline engines that power lawn mowers, gardening equipment, and snow blowers, as well as the motors that run small boats and snowmobiles, are less tolerant of ethanol. Some owners blowers and weed whackers are used to the idea of those machines being disposable, only good for a year or two if fueled by ethanol blended fuel.

My working headline for this post originally ended “New Rule Satisfies Nobody,” but that’s not entirely true. The acting assistant administrator for the EPA’s Office of Air and Radiation, Janet McCabe, said that, “This administration is committed to keeping the RFS program on track, spurring continued growth in biofuel production and use, and achieving the climate and energy independence benefits that Congress envisioned from this program.” McCabe called the RFS a “success story,” pointing to the U.S. as the largest producer of biofuels in the world.

Under federal rule-making legislation, the EPA is accepting comments on the proposed changes until July 11. A public hearing on the increased biofuels mandate will be held in Kansas City on June 9.

* One exception is Koch Industries, the fifth largest producer of ethanol in the U.S. The Koch brothers oppose the ethanol mandate and renewable fuel subsidies on libertarian grounds.

    i just wish I had a choice.... My cars don't care, but I'd like to buy real gas for my jetski...I've rebuilt the carbs twice. The closest real gas to me is over 150 miles away. What was a good idea at the time is now corporate welfare for Big Ag.

    A cash cow for companies like ADM , and a political snowjob by self interested politians like Chuck Grassley. Ethanol blends have done no real good and have indeed proved harmful as well as useless. Yet another case of money influence screwing the public good.

      I would nominate Iowa as having just about the worst senators of any state at the moment, Chuck Grassley and Joni Ernst are both unbearable. Ugh. I didn't vote for Ernst, and this fall will be the first time I can even vote for or against Grassley.. he shouldn't count on my vote.

  • 285exp I am quite sure that it is a complete coincidence that they have announced a $7k price increase the same week that the current administration has passed legislation extending the $7k tax credit that was set to expire. Yep, not at all related.
  • Syke Is it possible to switch the pure EV drive on and off? Given the wonderful throttle response of an EV, I could see the desirability of this for a serious off-roader. Run straight ICE to get to your off-roading site, switch over the EV drive during the off-road section, then back to ICE for the road trip back home.
  • ToolGuy Historical Perspective Moment:• First-gen Bronco debuted in MY1966• OJ Simpson Bronco chase was in 1994• 1966 to 1994 = 28 years• 1994 to now = 28 yearsFeel old yet?
  • Ronnie Schreiber From where is all that electricity needed to power an EV transportation system going to come? Ironically, the only EV evangelist that I know of who even mentions the fragile nature of our electrical grid is Elon Musk. None of the politicians pushing EVs go anywhere near it, well, unless they are advocating for unreliable renewables like wind and solar.
  • FreedMike I just don’t see the market here - I think about 1.2% of Jeep drivers are going to be sold on the fuel cost savings here. And the fuel cost savings are pretty minimal, per the EPA: fuel costs for this vehicle are $2200 and $2750 for the equivalent base turbo-four model. I don’t get it.
