Ozone Standards

ASU Workshop on EPA Ozone Standards (Feb. 24, 2015)

The US EPA has proposed a new rule that would alter the National Ambient Air Quality Standard for Ozone, from the current 75 parts per billion to between 65 and 70 ppb.  ASU hosted a workshop on Feb. 24th, 2015, to discuss how ozone is formed, how it is measured in Arizona and the wider West, and the potential implications of the EPA’s new ozone proposal. Slides presented at the workshop are available from the links below.
