For the first time since September, state officials have declared today an Ozone Action Day in the Austin-area. The declaration means weather conditions are expected to be conducive to lower-than-normal air quality.
The Air Quality Index is forecast to bad enough to affect sensitive groups, such as those with asthma or heart disease, elderly people and children. The general public should be okay.
The U.S. Environmental Protection Agency sets a minimum standard for ozone of 75 parts per billion.
“Our standard last year, we ended the 2013 ozone season at 73 parts per billion, so we’re actually okay, for now, but EPA expects to announce a new ozone standard in December of this year,” Clean Air Force of Central Texas director Sarah Holland says.
