The Environmental Protection Agency has released new rules to reduce ozone pollution.  The Austin area has managed to stay on the right side of current rules, but the new standards will be harder to meet.

This week the US Environmental Protection Agency is expected to announce new limits on the amount of ozone Americans breathe. Those limits could force Austin and other Texas cities to reduce ground-level ozone pollution in an effort to mitigate the pollutant’s harmful health effects.

Over the objections of Texas officials, the Obama administration on Wednesday proposed a long-delayed rule to slash levels of ozone – a smog-forming pollutant known to worsen asthma, lung disease and heart conditions.

The regulation is the latest example of the federal Environmental Protection Agency's use of the Clean Air Act to crack down on the pollution wafting from factories, power plants and tailpipes.


Update: Today's the third Ozone Action Day of the year. Austin remains dangerously close to falling out of attainment of the clean air standard of 75 parts of ozone per billion. At last check, Austin was at 72.

“Being a non-attainment area it’s much harder to recruit business. It also accounts for a lot of absenteeism in schools because a lot of children have asthma and air pollution has been found to directly exacerbate asthma in children," Deanna Altenhoff, Executive Director of Clean Air of Central Texas, said.

Central Texas is under an Orange ozone alert, meaning the air is unhealthy to people who have breathing difficulties. It happens on the day a report is issued that claims the state could see more ozone action days in the future.

The EPA has once again delayed releasing stricter ground-level ozone standards. Those were supposed to be issued on July 29. This is the fourth time the EPA has delayed releasing exact standards.

The Bush Administration set the ozone standard at 75 parts per billion in 2008 even after EPA scientists had recommended a more stringent standard. The EPA has indicated that the new standard would fall between 60 to 70 parts per billion.

EPA press secretary Brendan Gilfillan issued this statement in announcing the delay.

It's that time of year again. 

April 1 to October 31 is ozone season in Central Texas.  These are the months when we expect the highest amounts of ground level ozone in the air. Last year, the Austin area came dangerously close to falling out of attainment of the federal clean air standard of 74 parts of ozone per-billion.  With the Environmental Protection Agency set to announce even stricter standards, it could be even harder for the region to stay in attainment this year.
