Efficient producer status given to 7 more Poet plants

By Susanne Retka Schill | March 27, 2017

Seven more Poet plants received letters from the U.S. EPA dated March 13 that their efficient producer status’ have been approved. Efficient producers have demonstrated their greenhouse gas (GHG) emissions show a reduction of at least 20 percent from the baseline gasoline, opening the way for the plants to generate renewable identification numbers above their grandfathered volumes.

The seven Poet Biorefinining plants include the 55 MMgy plant at Caro, Michigan, showing a 21.3 percent GHG reduction; 72 MMgy plant at Corning, Iowa, 21.1 percent reduction; 58 MMgy plant at Emmetsburg, Iowa, 23.2 percent reduction; 72 MMgy plant at Gowrie, Iowa, 22.7 percent; 58 MMgy plant at Hanlontown, Iowa, 20.5 percent; 58 MMgy plant at Hudson, South Dakota, 20.1; and 72 MMgy, Jewell, Iowa, 24.2.  The total number of Poet plants receiving EP3 status now number 15.

Plants applying for the efficient producer petition process (EP3), provide EPA data about their corn use and ethanol yield, used in the life-cycle analysis for the corn feedstock, plus data on energy consumption, used in the process emissions calculations. They are required to submit ongoing data to show the rolling daily average emissions continue to meet the target.

The EPA modeling done initially for the Renewable Fuels Standard rule found the average U.S. ethanol had GHG reductions of 16.8 percent for a natural gas fired dry mill, 100 percent DDGS production and with no advanced technologies. Nearly half of the emissions were from the controversial international indirect land use change. Existing plants at the time the rule went into effect were grandfathered in, but limited to RINs generation at their grandfathered, registered volume. To date, 75 ethanol producers that had been grandfathered in have demonstrated emissions profiles better than 20 percent.
