Notice is given to the public, according to Chapter 14 of Title 129 - Nebraska Air Quality Regulations, for a Class II operating permit for Siouxland Ethanol, LLC (FID # 85434) an ethanol manufacturing plant (Standard Industrial Classification code 2869) located at 1501 Knox Boulevard, Jackson, Dakota County, Nebraska. The potential emissions of regulated air pollutants (in tons per year (tpy)) at this facility will be: 62.25 tpy of Particulate Matter (PM), 48.99 tpy of PM ≤ 10 microns (PM10), 24.64 tpy PM ≤ 2.5 microns (PM2.5), 3.18 tpy Sulfur Dioxide, 94.74 tpy Oxides of Nitrogen, 97.20 tpy Carbon Monoxide, 89.32 tpy Volatile Organic Compounds, 9.76 tpy of Acetaldehyde, 1.76 tpy of Acrolein, 0.06 tpy 1,3-Butadiene, 2.34 tpy Hexane, 0.35 tpy Polycyclic Organic Matter, 0.16 tpy Vinyl Chloride, 0.33 tpy Vinylidene Chloride, 15.07 tpy total HAPs, and 382,051.59 tpy Greenhouse Gases CO2 equivalents (CO2e).

Dakota County meets the National Ambient Air Quality Standards (NAAQS) for those pollutants subject to a NAAQS and is expected to continue in that status. Dakota County is unclassifiable in regard to the state Total Reduced Sulfur (TRS) standards and no TRS emissions are expected from this project. No impact is anticipated on habitat for any rare or threatened species.
