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

Fremont County, Wyoming; Goshen County, Wyoming; and Hot Springs County, Wyoming.  The Fremont County Seat is Lander, Wyoming; the Goshen County Seat is Torrington, Wyoming; and the Hot Springs County Seat is Thermopolis, Wyoming.
