...OZONE ACTION DAY ALERT FROM 400 PM FRIDAY UNTIL 400 PM
SATURDAY...

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 Friday June 11 to 400 PM Saturday June 12

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. Saturday, June 12, 2021.  Ozone concentrations are expected
to reach the Unhealthy for Sensitive Groups category on Saturday.
The highest concentrations of ozone are most likely for locations
in the southern and western portions of the Denver Metro area, and
northward along the Front Range and lower foothills to include
Boulder, Longmont, and Fort Collins. 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.
