Ozone Season 2014

The 2014 ozone season is over and Central Texas recorded its cleanest year, by far, since we began monitoring for ozone in 1997.

The U.S. Environmental Protection Agency (EPA) uses a three-year average to calculate a region’s compliance with its health-based ozone standard of 75 parts per billion (ppb). Central Texas had a 63 ppb reading this year, giving us a three-year average of 69 ppb, well within EPA’s current requirement.

For more information on what Central Texas is doing to address air quality, see the region’s Ozone Advance Program Action Plan.
