Lower corn prices

The Iowa Corn Growers Association estimates the proposal could cut by 1.3 billion bushels the amount of corn needed to make ethanol through 2016. That equals about 10 percent of the nation’s corn supply.

The weaker demand comes at a time when the nation has record corn supplies in bins, and farmers are struggling with reduced income projections.

Chad Hart, an Iowa State University economist, said he expects ethanol plants will continue to produce more than the levels set by Congress, offsetting lower corn demand. “It basically will hold the industry where it’s at,” he said.

Iowa economy, jobs

Groups such as the Iowa Renewable Fuels, the Iowa Corn Growers and others worry that EPA’s proposal will hurt the struggling rural economy. Already, U.S. farmers are expected to see a 32 percent income drop this year, primarily from lower commodity prices and record production.

Monte Shaw, executive director of the Iowa Renewable Fuels Association, anticipates that some U.S. biodiesel plants will be shuttered. While the biodiesel goals would grow from 1.63 billion gallons in 2014 to 1.9 billion gallons in 2017, U.S. capacity is around 2 billion gallons.

“Some plant somewhere will absorb that hit,” he said.

Price at the pump

Shaw believes that Iowans and other U.S. consumers are missing out at the pump with less aggressive ethanol goals. Iowa motorists, he calculates, could conservatively save $60 million by using E15 gasoline with 15 percent ethanol. Most motorists use E10 gasoline. E15 saves drivers 5 to 10 cents per gallon, he said.

Most consumers, however, probably are unaware they could be saving money, said Hart, the ISU economist. “You can’t miss what you don’t have.”

Lost opportunities

The biggest impact will be lost opportunities, with proposed “status quo” levels that aren’t likely to spark new development, especially the next generation of ethanol production.

Shaw said Iowa and the U.S. lose out to other countries, without stronger market demand.

Iowa is home to three cellulosic ethanol plants. Plants in Emmetsburg and Nevada use corn cobs, stalks and other crop residue to make ethanol; in Galva, the plant uses corn fiber within the kernel.

Shaw said DuPont, developing the Nevada plant, expected to license the technology across the U.S., but has primarily found interest in Europe, China and other countries.

In a statement, DuPont said the “uncertainty over the RFS has already reduced the investment momentum in the advanced and cellulosic sectors in the United States.”
