Notice is given to the public, according to Chapter 14 of Title 129 - Nebraska Air Quality Regulations, that the Department is proposing to issue a Class I operating permit to Omaha Public Power District (OPPD) – Nebraska City Station (Facility 58343) for an electrical generation power plant (Standard Industrial Classification code 4911 Electric Services) located at 5264 L Road, Nebraska City, Otoe County, Nebraska. The potential emissions of regulated air pollutants (in tons per year (tpy)) at this facility will be: 1,824.12 tpy of Particulate Matter (PM), 1,780.95 tpy of PM ≤ 10 microns (PM10), 1,776.08 tpy PM ≤ 2.5 microns (PM2.5), 17,389 tpy Sulfur Dioxide, 6,140 tpy Oxides of Nitrogen, 18,662.04 tpy Carbon Monoxide, 204.75 tpy Volatile Organic Compounds, 61.64 tpy of Hydrofluoric Acid, 82.57 tpy of Hydrochloric Acid, 8.73 tpy of Cyanide, 185.37 tpy total HAPs, and 12,610,094 tpy Greenhouse Gases CO2 equivalents (CO2e).

Otoe County meets the National Ambient Air Quality Standards (NAAQS) for those pollutants subject to a NAAQS and is expected to continue in that status. Otoe 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.
