The Indiana Department of Environmental Management (IDEM) has forecasted another statewide Air Quality Action Day (AQAD) for ozone for Friday, June 30.

Note: IDEM forecasts are based, solely or in part, on data from air quality monitors located throughout the state. IDEM encourages residents to heed the forecast. Air quality information for all Indiana counties can be found at SmogWatch.IN.gov. 

Some municipalities have additional open burning restrictions on AQADs. For more information, see idem.IN.gov/openburning/laws-and-rules.

Hoosiers are encouraged to visit SmogWatch.IN.gov to view current and forecasted conditions and subscribe to email alerts.

IDEM encourages everyone to help reduce PM2.5 by making changes to daily habits. You can:

  • Carpool or use public transportation.
  • Avoid using the drive-through and combine errands into one trip.
  • Turn off engines instead of idling for long periods of time.
  • Avoid using gas-powered equipment.
  • Conserve energy by turning off lights and setting the air conditioner to a higher setting;
  • Use propane gas instead of charcoal when grilling outdoors;
  • Reminder: Indiana’s open burning laws make it illegal to burn trash and generally prohibit open burning, visit IN.gov/openburning for more information.

Air Quality Action Days are in effect from midnight to 11:59 p.m. on the specified date. Anyone sensitive to changes in air quality may be affected when ozone levels are high. Children, the elderly, and anyone with heart or lung conditions should reduce or avoid exertion and heavy work outdoors.

Ground-level ozone is formed when sunlight and hot weather combine with vehicle exhaust, factory emissions, and gasoline vapors. Ozone in the upper atmosphere blocks ultraviolet radiation, but ozone near the ground is a lung irritant that can cause coughing and breathing difficulties for sensitive populations.

IDEM examines weather patterns and current ozone readings to make daily air quality forecasts. Air Quality Action Days generally occur when weather conditions such as light winds, hot and dry air, stagnant conditions, and lower atmospheric inversions trap pollutants close to the ground.
