WHEN...400 PM Friday July 19 to 400 PM Saturday July 20

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,

Moderate to Unhealthy for Sensitive Groups range on Friday and

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 non-ZEV vehicles (i.e.,
gas or diesel), be reduced to lessen the 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 Colorado air quality
