Willow Road, 5 miles west and 2 miles south of Odell, Gage County, Nebraska. The potential emissions of regulated air pollutants (in tons per year (tpy)) at this facility will be: 8.39 tpy of Particulate Matter (PM), 8.39 tpy of PM ≤ 10 microns (PM10), 8.39 tpy PM ≤ 2.5 microns (PM2.5), 4.29 tpy Sulfur Dioxide, 76.82 tpy Oxides of Nitrogen, 77.82 tpy Carbon Monoxide, 45.00 tpy Volatile Organic Compounds, and 0.96 tpy of Formaldehyde (largest quantity individual Hazardous Air Pollutant (HAP), 1.39 tpy total HAPs, and 151,613.80 tpy Greenhouse Gases CO2 equivalents (CO2e).
