GRAND FORKS, N.D., Jan. 7, 2026 /Ethanol Producer Magazine/ –The U.S. EPA in December 2025 released a draft permit for a Class VI carbon dioxide injection well for a project under development by PureField Carbon Capture LLC that would capture and sequester CO2 produced at PureField Ingredient’s ethanol plant.
PureField Ingredients operates a 55 MMgy ethanol plant in Russell, Kansas. If approved, the permit would allow for the capture and geological sequestration of up to 150,000 metric tons of CO2 annually for a period of 12 years—equating to a total permitted injection volume of 1.8 million metric tons of CO2. The CO2 would be injected into the Arbuckle Group, a porous underground geologic formation, at a dept of 3,448 feet below ground surface.
According to the EPA, the proposed carbon capture and sequestration (CCS) project includes monitoring wells within and above the injection zones, as well as soil vapor, seismic and ecology stress observation stations.
During the 12-year injection period and for 50 years after injection has ceased, the permit would require PureField Carbon Capture to test and monitor the condition of the wells, injection pressure, and the location and size of the injected CO2 plume.
A public comment period on the draft Class VI permit is open through Feb. 1. The EPA will also hold a public availability session and a public hearing on Jan. 22 in Russell, Kansas. Additional information is available under Docket ID EPA-R07-OW-2025-3852 on the Regulations.gov website.
