Permitting and Engineering Division
Notice is given to the public, according to Chapter 10 of Nebraska Administrative Code Title 129 - Nebraska Air Quality Regulations, that the Department is proposing to issue an air construction permit to KAAPA Partners Aurora, LLC (FID 87072), an existing ethanol plant (Standard Industrial Classification code 2869), for the modification of two (2) anhydrous ethanol tanks, ethanol loadout operations, DDGS operations, and carbon sequestration operations located at 2103 Harvest Drive, Aurora, Hamilton county, Nebraska.
The anticipated change in emissions of regulated air contaminants in tons per year (tpy) due to the proposed permit revision at this facility will be: -68.95 tpy of Particulate Matter (PM); -66.95 tpy of PM ≤ 10 microns (PM10); -64.73 tpy PM ≤ 2.5 microns (PM2.5); -83.85 tpy Sulfur Dioxide; -57.37 tpy Oxides of Nitrogen; -146.22 tpy Carbon Monoxide; -35.50 tpy Volatile Organic Compounds; -1.60 tpy of Acetaldehyde; and -0.47 tpy total Hazardous Air Pollutants (HAP). There are currently no Counties classified as being in non-attainment with the State Total Reduced Sulfur (TRS) standards. It is the source’s responsibility to ensure no take of threatened or endangered species result from the proposed revisions to the ethanol plant.
The Department proposes to issue a construction permit with specific conditions, based on Title 129, which allows for the increase in capacity of two (2) new anhydrous ethanol storage tanks, the modification of fermentation operations to integrate carbon sequestration operations, the addition of combined emissions limits to the RTO units involved in DDGS operations, and the modification of ethanol loadout operations to replace an existing flare and remove a flare that was not constructed. DDGS drying operations also includes an operational limitation to limit the four (4) dryers to 12,270 combined hours of operation per year. Modifications to ethanol loadout operations also includes an operational limitation that allows for only six (6) of the seven (7) loadouts to be used during any single liquid product loading event.
The proposed permit and supporting materials are available Wednesday, April 1st, 2026 through Thursday, April 30th, 2026 at the NDWEE, 245 Fallbrook Blvd, Suite 100, Lincoln, Nebraska 68521 and electronically at https://dwee.nebraska.gov.
