IDEM forecasts Air Quality Action Day for Thursday in 4 regions including West Central Indiana

The Indiana Department of Environmental Management (IDEM) has forecast an Air Quality Action Day (AQAD) for Thursday, June 20, 2024, in four Indiana regions.

Ozone levels are expected to be in the Unhealthy for Sensitive Groups range (Orange) in the following areas:

Central/East Central Indiana, including the cities of: Bloomington, Brookville, Columbus, Frankfort, Indianapolis, Greensburg, Kokomo, Lebanon, Martinsville, Muncie, Richmond and all other cities within the area. Southeast Indiana, including the cities of: Brownstown, Corydon, Jeffersonville, Madison, New Albany, Salem, Versailles and all other cities within the area. Southwest Indiana, including the cities of: Bedford, Bloomfield, Evansville, Huntingburg, Mount Vernon, Paoli, Princeton, Rockport, Tell City, Vincennes and all other cities within the area. Western/West Central Indiana, including the cities of: Crawfordsville, Covington, Delphi, Fowler, Greencastle, Lafayette, Newport, Monticello, Spencer, Sullivan, Terre Haute and all other cities within the area.

Continuing high temperatures that are expected to reach the lower 90’s, along with modest humidity, may lead to ozone levels that reach the Unhealthy for Sensitive Groups (USG) in those regions. IDEM forecasted Air Quality Action Days indicate anticipated higher levels of ground-level ozone and fine particulate matter only. Other factors may affect overall air quality.
