    E.P.A. Approves Higher Ethanol Levels in Gas

    By MATTHEW L. WALD

    WASHINGTON — The Obama administration made a gesture of support for the ethanol industry on Wednesday, with a declaration by the Environmental Protection Agency that gasoline retailers can sell fuel blends containing up to 15 percent ethanol for use in late-model cars.

    But it was unclear when drivers might find the new fuel mix. Numerous other changes would have to occur before gas stations will begin selling the blend, known as E15, including many approvals by states and significant changes to the infrastructure at most gas stations.

    The ruling, which was requested by ethanol producers, was widely expected but is the subject of heated debate over whether E15 is safe for cars and other gasoline-powered devices. Fuel sold today typically contains as much as 10 percent ethanol, but automakers and other critics say that a higher blend of ethanol could corrode engines.

    The agency said Wednesday that government testing found the blend would not damage the engines in cars with a model year of 2007 or later — about one in seven cars on the road — and would not cause unacceptable increases in air pollution. The agency is still testing cars for the 2001 to 2006 model years and expects to issue a ruling on those as soon as next month.

    Ethanol producers called the ruling a “good first step,” which ended the 30-year-old cap of 10 percent on ethanol for ordinary cars. “We know we have challenges on which we have to move forward,” said Tom Buis, chief executive of Growth Energy, the industry group that petitioned the E.P.A. for the change.

    Oil producers, gasoline retailers and the makers of gasoline-powered equipment denounced the decision, many of them in the hours before it was released. A spokeswoman for the auto manufacturers — which generally support renewable fuels but want additional testing before more ethanol is used in cars not designed for it — described the announcement as “ethanol creep.”

    Gina McCarthy, the E.P.A. assistant administrator for air and radiation, said that the decision advanced an important national goal of reducing oil consumption. The federal government would like to see Americans use 36 billion gallons of alternative fuels by 2022, including 21 billion from advanced biofuels beyond the corn-based ethanol that is prevalent now. Currently, the industry says it can produce about six billion gallons of corn ethanol a year.

    It was not clear why the agency made an announcement on one group of cars when a decision on another group is coming in a month or two, but analysts suggested that election-year politics played a role.

    Kevin Book, an analyst at ClearView Energy Partners, a research firm, said that in the midterm Congressional elections in three weeks, “there are nine at-risk Democrats from the top 10 ethanol producer states. If you’re fighting for every seat in a midterm election, you can’t afford to wait until the rule is finished.”

    But Ms. McCarthy said the agency was obligated to respond to a petition by an ethanol producer group, Growth Energy. It had originally intended to reply this summer.

    The first group of cars affected is small. R. L. Polk, the auto industry consultant, said that as of January, there were 231 million vehicles of the model year 1981 or later, of which 35 million, or 15 percent, were covered by Wednesday’s decision. Another 85 million vehicles, or 37 percent, are in the group for which a ruling could come next month. But the newer vehicles are driven more miles and burn a disproportionate share of the fuel.

    The fuel itself gets a mixed reception from environmental advocates. Ethanol production consumes prodigious quantities of natural gas, diesel fuel and other inputs that lead to carbon dioxide emissions. And it contributes to the demand for corn, helping to drive up the cost of that commodity, raising food prices and diverting farmland that could be used for growing crops for human consumption.

    It also pits farmers against car owners. Ethanol can eat away at the seals in engines and fuel systems that are not designed for its use. The E.P.A. said that cars sold in the 2007 model year and later were more able to withstand ethanol because they were built to tighter pollution standards and that older cars might be able to accept higher blends as well.

    But the automakers and fuel suppliers fear liability if the higher-ethanol fuel damages engines. Hand-held garden equipment and boat engines could fail in ways that create safety problems, people in those industries say.

    Ethanol also evaporates more easily than gasoline, which can put an ingredient of smog into the air.

    A more practical barrier to widespread adoption of E15 are the gas stations that would sell it. Even if a station has enough pumps to offer a new grade of fuel, most have too few underground tanks, experts say.

    Stations that sell regular, midgrade and premium fuel typically do it with one tank of regular and one of premium; the pump blends the two for midgrade. For them, going to E15 would mean giving up sales of premium, said Prentiss E. Searles, the marketing issues manager at the American Petroleum Institute, the trade group for the oil industry.

    “If you’ve got a limited number of vehicles that can use E15, it doesn’t make a lot of sense,” Mr. Searles said.

    John Eichberger, a spokesman for the National Association of Convenience Stores, which represents 115,000 of the about 160,000 locations in the United States that sell gasoline, said that some gas stations might sell E15 by giving up selling diesel fuel.

    Mr. Eichberger said many other state and federal regulations would have to change before E15 could be legally sold. But the basic problem, he said, was that “we don’t have a retail infrastructure that can handle the product, we don’t have consumers ready to buy it, and we don’t have the auto industry ready to approve the use in their cars.”

    Even gas pumps aren’t certified for E15, Mr. Eichberger said.

    He and others said that once the fuel was offered for some cars, it would be mistakenly used in others. It is likely to sell for less per gallon, making it look attractive to buyers, although it may turn out to be more expensive per mile, because ethanol has less energy than gasoline.

    But Todd Becker, the chief executive of Green Plains Renewable Energy, said that the decision “tells the investment community that this is an expanding sector of the energy market.” Ethanol’s biggest problem, he said, is access to the retail market, which he complained was controlled by oil companies.

    The problems of E15 could mirror those of E85, an 85 percent blend of ethanol. While the auto companies have made millions of vehicles that can use it, most of them still fill up on regular gas because very few places sell E85.

    Offering Donors Secrecy, and Going on Attack

    By JIM RUTENBERG, DON VAN NATTA Jr. and MIKE McINTIRE

    The American Future Fund, a conservative organization based in Iowa, has been one of the more active players in this fall’s campaigns, spending millions of dollars on ads attacking Democrats across the country. It has not hesitated to take credit for its attacks, issuing press releases with headlines like “AFF Launches TV Ads in 13 States Targeting Liberal Politicians.”

    Like many of the other groups with anodyne names engaged in the battle to control Congress, it does not have to identify its donors, keeping them — and their possible motivations — shrouded from the public.

    But interviews found that the group was started with seed money from at least one influential Iowa businessman: Bruce Rastetter, a co-founder and the chief executive of one of the nation’s larger ethanol companies, Hawkeye Energy Holdings, and a rising force in state Republican politics. And hints of a possible agenda emerge from a look at the politicians on the American Future Fund’s hit list. Most have seats on a handful of legislative committees with a direct say in the ethanol industry.

    Re: EPA in Forefront in Rational Use of Energy

    The ONLY time one should have ethanol blended into gasoline is when the real temperature outside is near -40F (-40C). Wind-chill does not count.......Otherwise, ethanol is a waste of money because ethanol does NOT have the energy content of gasoline; its octane is much lower. Ethanol, therefore, is a filler, not a fuel.

    And the rip-off is three-fold: 1.) Ethanol-blended fuel is nearly the same price as regular gas, so it costs more to drive per mile; 2.) Ethanol-blended fuel burns faster, so you have to fill-up every day, even driving in-town. It's a joke on the consumer. 3.) Food prices rise, especially the price of corn and corn-flakes. Also, farmland is taken-out of food production, so food prices rise due to a shortage of land, not just corn.

    Ethanol is another scam perpetrated by the EPA and its eco-frauds. Their accounting is suspect, as usual. Ethanol is a big money-loser for everyone, except for grain-farmers, Congress, lobbyists, and oil refiners.

    A cleaner fuel? What does that mean, especially when the consumer has to burn more of it to travel the same distance?

      One bullet, two heads: when big government = big corporations who do you shoot? Which is most essential to the continuation of everyday life? It's a tossup to me since the healthiest parts of the economy have no lobby and the most destructive, private elements have all the influence.

        It seems that way to me too. I suspect it's because the healthiest parts do not require substantial government influence while the destructive, parasitic parts need a strong host to suck blood from. That just seems like common sense though.

        Also the price of beef and other meats where corn is a feedstock goes up.

          You got to love this part though:

          "It also pits farmers against car owners. Ethanol can eat away at the seals in engines and fuel systems that are not designed for its use. The E.P.A. said that cars sold in the 2007 model year and later were more able to withstand ethanol because they were built to tighter pollution standards and that older cars might be able to accept higher blends as well.

          Safety, smafety. And those new engines are MORE ABLE to withstand the ethanol.....

          ...great, so the seals won't fail as quickly as compared to the newer cars....

          Give credit to the EPA, they're going to reverse engineer us into the dark ages.

            You are generally correct in your main points, Steve (allowing for some dramatic exaggeration of severity). I did much formal published research on ethanol and other alternative fuels years ago.

            I would, however, correct your use of "octane" above. The octane rating of a fuel is completely unrelated to its energy content. Instead, it tells you something about its combustion characteristics, more specifically about how prone it is to detonation in a spark-ignited engine, commonly called “knock”. The alcohols fuels actually have superior octane ratings.

                Yes.

                Inside the cylinder of a spark-ignited engine, you want combustion to begin at the spark plug and have the flame front spread outwards in all directions evenly. Of course, pressures and temperatures are high in the cylinder just before the spark plug fires, and once combustion begins they jump up even more. Sometimes a second or third fire breaks out, and the whole air/fuel charge burns much more rapidly. The result is an undesired spike in pressure that creates a rattling sound you can hear; we call it knock. It can damage the engine parts.

                As you increase engine compression ratio, the tendency to knock goes up. You get higher performance from a higher compression engine, but must use higher octane fuel to fight against knock. That’s why high performance and luxury cars use premium fuel.

                Alcohol fuels are resistant to detonation. Blending in ethanol to gasoline improves the octane rating but lowers the energy content of the fuel. Racing cars with unusually high compression engines run very well on alcohol.

                Oh no; we've hijacked another thread to talk cars and engines.

                  I think you meant to say they won't fail as quickly as compared to the older cars.

                  As the owner of a 1999 Honda, I do worry somewhat about reports of ethanol damaging seals of older cars. I plan to drive this thing until the wheels fall off. Fortunately public transit and walkable destinations limit how much I drive, so I expect the car to last me a long time, if it doesn't corrode in the driveway.

                  Here's a couple more unhappy bits of info.

                  From a Congressional Research Service report:

                  Currently, no automaker warranties its vehicles to use gasoline with higher than 10% ethanol.
                  So you pump your relatively new car full of E15 and it causes problems... you take it to the dealer mechanic and they say, no warranty coverage for you?

                  Also, Underwriters Laboratories has said:

                  Under normal business conditions, E10 at the dispenser can vary from about seven to 13 percent ethanol.
                  So who knows how much ethanol you're really getting?

                    I drive a 1995 mazda, and live in illinois which in order to satisfy the corn lobby here I think our gas has been ethanted since that time. I think I have been using 10% ethanol for the entire life of the vehicle. I drive the car nearly every day and have 195K on it. I have never had a fuel or engine related problem. So 10% seems OK. Of course I cannot speculate on what 15% might do.

                      I was listening to a radio show yesterday where they were discussing the use of Ethanol in gasoline. The caller claims he got worse mileage with Ethanol and the host claimed it damages engines. He also claimed ethanol is merely a subsidy for the corn growers.

                        It will definately give lower MPG; ethanol has less BTU per gallon than gasoline has. When you blend ethanol (or methanol) into gasoline you lower the energy content of the fuel. Blended to E20 (20% ethanol and 80% gasoline) the fuel will drop your MPG 7.7%.

                        It won't damage your engine. Up to the amount your car manufacturer warranties (usually E10 or E15) you're all clear. Higher blends than that could possibly soften or erode seals or elastomeric tubing, but I wouldn't worry up to E20.

                        Every Indy car has run on pure alcohol since the mid 1960s. Recently they changed from methanol to ethanol for publicity reasons, urged by the ethanol industry. The cars still go 200+ MPH (but they had to change the rules to allow bigger engines for ethanol -less energy in the fuel).

                        Best info source is the National Renewable Energy Lab. Here's a link to a recent ethanol news blurb. http://www.nrel.gov/features/20090918_ethanol.html
                        They also have more serious scientific papers available there.

                        Widespread use of ethanol fuel is a major goal of the corn industry and ADM; the vehicle fuel market is a huge, even compared to food. Those agri-business players will never stop pushing for it.

                        Glancing over the news release and the report referenced, I was surprised to see the problems that small utility engines have with E20 -chain saws and weed trimmers don't run well on E20 without some serious adjustment!

                            The effect of E20 on the little engines is to make the carburetors run too lean for the E20; they idle too fast and run hot. Machines like chainsaws and weed trimmers have a centifugal clutch, so the darn things race and engage the cutter upon starting with E20.
                            Modern cars are fuel injected and computer controlled, so they automatically adust themselves to ethanol blends.

                              1) My dad had to replace a gasket/valve/rubber thing on the heads of his 1997 van, It was old but, the car only has 120,000 mileage and you would expect the head gasket to not completely rot through like it did.

                              2) I have had to adjust my leaf blower with these 2 screws for idle speed and mixture whenever I mix in new gas, could be for ethanol adjustment, weird though.

                              3) The fresh water which is drained from aquifers and wells will lead to shortages in the future. This is probably the most over looked part of the ethanol lie.
