...AIR QUALITY ALERT IN EFFECT UNTIL MIDNIGHT EDT TONIGHT...
The officials at the Office of Sustainability for the City of
Indianapolis have called for a Knozone Action Day, IN EFFECT UNTIL

A Knozone Action day means that a combination of high temperatures,

where high levels of ozone emissions may exceed federally mandated
standards.
Fine particulate levels are expected to be in the Unhealthy for
Sensitive Groups range. Active children and adults, and people with
respiratory disease, such as asthma should limit prolonged outdoor
exposure.
Here are some recommended actions that the public can take:
* Walk, bike, carpool or use public transportation.
* Avoid using the drive-through and combine errands into one trip.
* Avoid refueling your vehicle or using gasoline-powered lawn
equipment until after 7pm.
* Turn off your engine when idling for more than 30 seconds.
* Conserve energy by turning off lights or setting the air
conditioner to 75 degrees or above.
