The Savannah air monitoring station is located downwind of St. Joseph to help determine the exposure of a segment of residents in the St. Joseph metropolitan area to ground-level ozone and to monitor attainment of the ambient air quality standards.

Ozone (O3) Data*

The federal season for ground-level ozone runs from March 1 through October 31. Ground-level ozone forms when pollutants emitted by cars, factories, power plants and other sources react chemically in the presence of heat and sunlight. Ozone at ground level is a harmful air pollutant as opposed to ozone in the upper atmosphere, which protects us from ultraviolet light.

As of 2015, the federal standard for ground-level ozone is 70 parts per billion. An area is in compliance if the design value is at or below this standard. A design value for ozone incorporates data from three years. The department and
EPA calculate the design value by 1) ranking the daily eight-hour ozone values for three consecutive years; 2) extracting the fourth-highest value for each year; and 3) averaging the three figures.
