Here’s what you can do for our air With weather conditions as they are, you may soon hear that the city has called for a Knozone Action Day. According to a release from the City of Indianapolis, these come when conditions in the atmosphere are favorable for the formation of ground-level ozone, or smog. Smog restricts the ability of your lungs to process oxygen, irritates your throat, makes you cough and your chest feel tight. Don't mow until 6 p.m. on Knozone days. People with asthma or other respiratory diseases are especially at risk. To help make a visible difference in Central Indiana’s air quality, follow these steps to help us all breathe a little easier at work, at home and at play.  What you can do: • Wait to fill your gas tank or mow your lawn until after 6 p.m.

• Keep your car tuned up and tires properly inflated.

• Avoid using drive-thru windows; go inside instead.

• Walk or ride your bike short distances, instead of driving.

• Carpool or take the bus. Call IndyGo at 317-635-3344 for route information.

• Use water-based paints and solvents.

• Plan outdoor activities for early morning or evening when ozone levels are lower, especially if you have asthma or other lung diseases.

• Combine small errands into one trip.

• Be careful not to spill fuel when filling gas tanks for your car or lawn equipment.

• Avoid burning yard debris.

What businesses can do:• Fuel fleet vehicles late in the day.

• Limit or halt non-essential operations like asphalting a parking lot or painting a building.

• Distribute e-mail or voice mail reminders on Knozone Action Days.

• Limit truck deliveries.

• Organize company carpools or vanpools. Contact Central Indiana Commuter Services at 317-327-RIDE for more information.

• Flex work schedules so operations don’t occur at peak ozone hours.

• Subsidize IndyGo transportation. Call 317-635-3344 for more information.

Knozone is a voluntary air pollution reduction program for Indianapolis-Marion County and is funded through a federal Congestion Mitigation and Air Quality grant. Now in its 10th year, the program educates the public about the effects of ground-level ozone (smog) and fine particles (soot) on public health and the environment. For more information, visit or call 317-327-4AIR for current air quality information.
