Abstract: The Environmental Protection Agency (EPA) compiles data on emission tonnages of air pollutants for US counties.  US Air Quality Gradebook ("AirGrades") source sheets give the percentage contributions from specific air pollution sources.  This source sheet is for

Johnson County, Kansas; Kearny County, Kansas; and Kingman County, Kansas.  The Johnson County Seat is Olathe, Kansas; the Kearny County Seat is Lakin, Kansas; and the Kingman County Seat is Kingman, Kansas.
