...OZONE ACTION DAY ALERT FROM 400 PM TUESDAY UNTIL 400 PM
WEDNESDAY...

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 Tuesday August 03 to 400 PM Wednesday August 04

IMPACTS...Ozone Action Day Alert is now in effect for the Front
Range Urban Corridor. Requests to limit driving of non-ZEV
vehicles (i.e., gas or diesel) are now in effect until at least 4
p.m. Wednesday, August 4, 2021.  Although ozone will generally be
at moderate levels on Tuesday, higher ozone concentrations are
expected Wednesday afternoon and early evening. Ozone
concentrations in the Unhealthy for Sensitive Groups category will
be most likely Wednesday afternoon and early evening for southern
and western portions of the Denver metro area, including Highlands
Ranch and Golden. 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 conditions, forecasts and advisories, visit:

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
