The U.S. Environmental Protection Agency (EPA) sets National Ambient Air Quality Standards (NAAQS) to protect the public from the harmful effects of air pollutants. Revised in 2015, the current NAAQS for daily maximum ozone is 70 parts per billion (ppb). All areas in Minnesota currently meet the ozone NAAQS. However, an area can meet the federal regulatory requirements and still experience days where air quality is a health concern, particularly for vulnerable populations.
The Minnesota Pollution Control Agency (MPCA) monitors ozone pollution at locations across Minnesota from March through October each year. Because ozone formation requires high temperatures and sunlight, ozone concentrations are not expected to exceed the standards outside of the warmest months of the year.
