WHEN...400 PM Friday July 12 to 400 PM Saturday July 13

IMPACTS...Ozone Action Day Alert is now in effect for the Front
Range Urban Corridor. Request to limit driving gas and diesel-
powered vehicles is now in effect until at least 4 p.m. Saturday,

of ozone on Friday and Saturday. The highest concentrations of
ozone are most likely for locations in and near the Denver Metro

Front Range region. For areas included in this advisory that are
not expected to reach the Unhealthy for Sensitive Groups (USG) air
quality designation, we request that activities, such as driving

impacts on neighboring air quality. Additional air pollution in
this region may directly worsen air quality or contribute to
precursors which may also adversely affect air quality.  For
