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 Thursday July 04 to 400 PM Friday July 05

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. Friday,
July 5, 2024.  Light winds and sunny skies are expected to allow
ozone levels to reach the Unhealthy for Sensitive Groups category
on Thursday and Friday. The highest concentrations are expected in
locations in and near the Denver Metro area. 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.
