Iowa has generally good air quality thanks to low population density and open terrain. Agricultural operations, especially large hog confinements and ethanol plants, are the primary air quality concerns in rural areas.
Iowa DNR Air Quality Bureau manages standards. Large livestock operation permits required. Ethanol plant emission limits.
No current nonattainment areas. Iowa generally meets all federal air quality standards.
