West Virginia's air quality is tied to its coal and chemical industries. The Kanawha Valley around Charleston has the highest concentration of chemical plants. Coal mining and power generation are declining, which is gradually improving air quality across the state.
WV DEP Division of Air Quality manages standards. Coal industry emission permits. Chemical Valley (Kanawha) enhanced monitoring.
No current nonattainment areas, though the Kanawha Valley has historically been close. Coal plant retirements are improving air quality.
