Facts
- 15 counties in metro Atlanta have been classified by the U.S. EPA as a serious nonattainment area for ground-level ozone, a major component of smog.
- For many days during smog season - May 1 to September 30 - ozone levels are likely to exceed federal limits.
- Poor air quality threatens our economic prosperity, poses risks to human health, and is detrimental to the environment.
- Smog is created from a combination of pollutants that come from vehicle emissions, industrial and utility plants, and other sources, including nitrogen oxide (NOx), volatile organic compounds (VOCs) and particulate matter (PM).

Recipe for Smog:
Ozone forms over the course of the day as temperatures rise and air moves across the region, and levels can vary significantly over the day. Highest ozone levels usually occur on summer afternoons between two and seven p.m.
