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

Bedford County, Tennessee; Benton County, Tennessee; and Bledsoe County, Tennessee.  The Bedford County Seat is Shelbyville, Tennessee; the Benton County Seat is Camden, Tennessee; and the Bledsoe County Seat is Pikeville, Tennessee.
