The Colorado Department of Public Health and Environment has
issued the following...

WHAT...Ozone Action Day Alert.

WHERE...Douglas, Jefferson, Denver, western Arapahoe, western
Adams, Broomfield, Boulder, Larimer, and Weld Counties

WHEN...400 PM Saturday June 22 to 400 PM Sunday June 23

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. Sunday,
June 23, 2024.  Increased concentrations of ozone continue to be
of concern on Saturday and Sunday. Ozone concentrations in the
Unhealthy for Sensitive Groups category are most likely for
locations in and near the Denver Metro area, particularly in
locations to the south and west, including the foothills. 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 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

HEALTH INFORMATION...Increasing likelihood of respiratory symptoms
and breathing discomfort in active children and adults and people
with lung disease, such as asthma. Active children and adults, and
people with lung disease, such as asthma, should reduce prolonged
or heavy outdoor exertion.
