NAAQS (2008 Proposed)


Changing Standard - Ozone

• 1979 – 0.12 ppm, 1-hr avg– Health Effects (from preamble to final

standard): • irritates mucous membranes, lung tissues• reduces lung function• causes chest tightness, coughing wheezing• increases asthma attacks• increased susceptibility to bacterial infections• accelerates aging


Changing Standard - Ozone• 2008 – 0.075 ppm, 8-hr avg

– Health Effects (from EPA presentation)
