Alba's design value for ozone peaked at 78 parts per billion (ppb) during the 2010-2012 period.
The year 2012 was especially hot, and many sites registered higher than usual levels of ozone.
The most recent quality assured data show ozone levels below the 2015 EPA standard of 70 parts per billion.
In the Earth's lower atmosphere, near ground level, ozone is formed when pollutants emitted
by cars, factories, power plants, and other sources react chemically in the presence of sunlight.
Ozone at ground level is a harmful air pollutant. (Note that 70 parts per billion equal 0.070 parts per million.)

Ozone Data*

The federal ozone season for monitoring runs from Mar. 1 to Oct. 31.

As of 2015, the federal standard for 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.
