Another Knozone Action Day declared for Indianapolis

Indianapolis will have its sixth Knozone Action Day of the season on Wednesday.

The city's Office of Sustainability declared the Knozone Action Day, noting the possibility of poor air quality and temperatures topping 90 degrees.

Residents can limit heightened ozone levels by not using gas-powered lawn equipment, avoiding idling while driving, and refueling gas-powered vehicles and equipment until after 7 p.m.

Knozone Action Days are issued when ozone or fine particulate matter levels rise above certain thresholds. On those days, the air quality may become unhealthy for sensitive individuals, especially active children, the elderly, and anyone with asthma, lung disease, COVID-19, or other serious health problems.
