IMPACTS...Ozone Action Day Alert is now in effect for the Front

areas included in this advisory that are not expected to reach the
Unhealthy for Sensitive Groups (USG) air quality designation, we

worsen air quality or contribute to precursors which may also
adversely affect air quality.  For Colorado air quality
