Metro Goverment Predicts Unhealthy Air Tomorrow, Thursday

The Louisville Air Pollution Control District is forecasting unhealthy levels of ozone for Independence Day and July 5.

The high temperatures and lack of wind will trap pollution near the city, raising ozone levels. The city's air is expected to be a 122 on the Air Quality Index tomorrow, which is unhealthy for sensitive groups. It's predicted to be slightly lower on Thursday--a 116--but still unhealthy for sensitive groups. These are the 15th and 16th Air Quality Alerts of the summer.

A federal court of appeals has ruled that the Environmental Protection Agency can regulate carbon emissions from vehicles and power plants.

A coalition of energy companies, manufacturers and individual states—including Kentucky and Indiana—challenged the rules in court. They argued that a core provision—the finding that greenhouse gases, like carbon dioxide are pollutants and pose a danger to human health—wasn’t based on science. And without that finding, they argued the federal government couldn’t set standards for vehicle and power plant carbon dioxide emissions.

Reducing Idling Could Lead to Fewer Air Quality Alerts

So far this year, there have been ten days when air quality is forecasted to be bad in the Louisville area, and as the summer wears on there will be many more. The weather plays a big part in these days of unhealthy air, and pollution from industries contributes, too. But individual actions can also affect the air.

Air Quality Alert Called For Saturday, Sunday

Louisville’s Air Pollution Control District has called an Air Quality Alert for this weekend.

The alerts this weekend are the ninth and tenth times this year the Air Pollution Control District has forecasted that ozone levels will be unhealthy for sensitive groups. But the alerts are forecasts—and the actual air quality has only been unhealthy twice so far.
