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

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 August 11 to 400 PM Friday August 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. Friday, August 12, 2022.  Ozone concentrations in the
Unhealthy for Sensitive Groups category are likely both Thursday
and Friday during the afternoons and evenings. On Thursday, ozone
concentrations in the Unhealthy for Sensitive Groups category are
likely throughout the northern Front Range region. On Friday,
ozone concentrations in the Unhealthy for Sensitive Groups
category will mainly be confined to locations in and near the
Denver metro area, along with southern parts of Weld County. 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
or heavy outdoor exertion.
