    EPA scales back on ethanol requirements | StateImpact Pennsylvania

    The Shell station at 12th and Vine Streets in Philadelphia offers gasoline mixed with corn-based ethanol and features a mural paying homage to corn.
    The EPA is cutting back on the amount of corn-based ethanol American refineries will be required to blend into their gasoline supplies, a victory for the oil industry and lawmakers who have been fighting the mandate.
    That means what you’re pumping at the gas station will have less ethanol in it, an alcohol made from distilling corn that emits less carbon dioxide than when gasoline burns.
    The announcement comes just days after an Associated Press investigation showed the hidden environmental costs of the ethanol mandate, known as the “renewable fuel standard.”
    More from the Wall Street Journal:
    The EPA’s proposal, which will be open to 60 days of public comment before being made final in the spring of next year, trims volume requirements for all kinds of biofuels. The EPA proposed that between two billion and 2.5 billion gallons of advanced biofuels be blended into the nation’s fuel supply. That’s significantly less than the 3.75 billion gallons mandated by the 2007 law for advanced biofuels, a category that includes fuels made from things other than corn.
    Those volumes would leave between 12.7 billion and 13.2 billion gallons of corn ethanol in the nation’s fuel mix. The EPA’s proposal would cut ethanol volumes not just lower than what was expected for 2014, but lower than what was mandated in the last two years.

    An administration official said the EPA remained committed to promoting biofuels and called the new levels “a sustainable path forward that allows for steady growth.”
    The EPA says it is trying to fix a problem known as the “blend wall,” which occurs when the annual requirement mandated by Congress exceeds the amount of ethanol that can be mixed into conventional blends of gasoline.
    The EPA’s decision is being praised by oil refiners who have been lobbying to eliminate the ethanol mandate altogether. Refineries can pay to opt out of the ethanol program by buying credits which Senator Pat Toomey (R-PA) argues is hurting refineries like those in southeast Pennsylvania. Toomey said the reduced standards don’t go far enough.
    “Even at the rolled back 2012 levels, these fuel standards are causing inflation at the grocery store, harming the environment, and amount to corporate welfare showered on a favored industry with the American people footing the bill,” he said in a press release following the announcement.
    The “favored industry” Toomey is speaking of is agriculture. Corn-producing states in the Midwest have been experiencing a boom since the ethanol mandate was passed by Congress in 2007. As the Associated Press reported, that boom has resulted insignificant environmental impacts like fertilizer pollution in waterways, the loss of preserved farmland and wetlands, and increases in greenhouse gas emissions.
    The agriculture and ethanol industries say the EPA’s decision will hurt farmers.
    “They’re capitulating to the oil companies,” Bob Dinneen, president of the Renewable Fuels Association, told the Washington Post. “The RFS was about forcing marketplace change… and EPA is giving the oil companies a get [out] of jail free card.”

    ...really not cutting back on ethanol%...just really correcting an error made by Congress in 2007. Congress had requested adding even more ethanol which is not working out, in part due to reduced demand for gasoline. I am not a big ethanaol fan, but OK makes some sense...we probably should have capped it at 5%.

    Evidently, all of the fuel and energy, as well as water, spent in plowing, cultivating and harvesting the fields, and processing became a diminishing return and became a zero or negative offset compared to the use of petroleum which has been proved more plentiful than expected.

    Increase in fuel economy has lessened demand for all fuels and driven down the cost to the end user, which is actually good for the economy.

    Cellulosic ethanol production remains a good investment.

    I really hope that people will continue to drive cars that get really good mpg. I think that will be important for our future. and I am really glad that we are not importing as much fuel from the middle east.

    In the late 1990's and early 2000's Ford and the EPA developed "Gasohol" using inexpensive Methanol produced form methane (natural gas) and coal.

    We should be using that instead of ethanol produced from corn. In China, it is illegal to make fuel from food.

    Ethanol from corn is used only because of the farm lobby in the US.

    Yep, if we're going to use ethanol, I rather see it made from waste than food.

    It's nice to see the recognition between the type of ethanol sources. But I sure hope people don't get confused. There's a plant about to open up in northern Iowa that will be using the cobs of the corn to produce ethanol. So technically, it's still corn, but waste rather than the food part. With all the anti-corn lobbying now, you could see that becoming a misunderstood issue.

    Talk about waste, if they could make ethanol out of politicians I'd be all for it. Maybe we could just squeeze it out of them. ;)

    Methanol from methane is a simple one step process. Methane is simply outgassed from garbage dumps. The BMW plant, here, down the street from me uses garbage dump methane. There are garbage dumps from the Ancient Roman Era still outgassing methane.

    Ethanol, even from waste products, takes a lot of energy and water. It has to be transported by truck or rail tank cars.

    Locally produced methanol produced from local garbage dumps will not require long distance transportation.


    Ethanol is political, and it benefits the farm lobby.

    Generalizations don't help.

    On the local level, it works fine and did for many years.

    Issues didn't arise until it was scaled up to the national level.

    Unfortunately, almost everything in this world is about politics and money.

    It's the Golden Rule.

    Those who have the gold, make the rules. They make the decisions on what they produce and generally "rules" over all of use who have less gold.

    I live in Oklahoma and when corn was used more for ethanal production, the price of cattle feed went up. Then price of beef went up. Then price of fuel went up. Then we started running low on corn. And cash to by corn.
    The corn cobb thing sounds really promising. How about cow patties and buffalo chips for fuel. Free and pluntiful.

    One corn fuel I like the idea are those corn pellet stoves for home heat.
    At least there you are not having to expend the energy to distill 12% ethanol out of the water.

    That might work better than the cow patties and buffalo chips. :)

    Which probably have a better chance of being made into diesel fuel. :D

    just a bunch of crap! the focus of the future in energy should be reduce waste and convert waste into useable energy. I saw a dairy that used the crap to make methanol and ran a generator that powered the dairy and had extra power to spare. they then bagged up the solids and sold for garden use. many think the earth is warming so lets catch as much sun as we can and use it to heat and power stuff.

    Several farms do this. It might be feasible for the large ones to convert some of the methane to methanol. Compresses it to run tractors likely has the lower upfront investment though.

    The only thing ethanol has going for it is that it is less toxic in the environment in the case of spills. Using the same feedstock, we can make about the same amount of butanol though. It has a higher btu content, and is more compatible with vehicles on the run now. It could possibly be pumped through the existing gasoline pipeline. That depends more on how powerful a cleanser is in the system than material compatibility. Ethanol is a strong one, and the cleaning out of decades of gunk could clog the system. At least, thousands of gallons of ethanol fuel blend will require filtering or become waste until the system is clean.
