410 PM MDT Thu Aug 5 2021

...ACTION DAY FOR MULTIPLE POLLUTANTS FROM 400 PM THURSDAY UNTIL
400 PM FRIDAY...

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

WHAT...Action Day for Multiple Pollutants.

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

WHEN...400 PM Thursday August 05 to 400 PM Friday August 06

IMPACTS...Action Day for Multiple Pollutants 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 6, 2021.  Concentrations of both ozone
and fine particulate matter are expected to reach the Unhealthy
for Sensitive Groups category on Thursday and Friday. Elevated
levels of ozone and fine particulates are possible throughout the
Colorado Front Range region including Colorado Springs, the Denver
Metro area, Boulder, Fort Collins, Greeley, and surrounding areas.
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:
https://www.colorado.gov/airquality/colorado_summary.aspx

HEALTH INFORMATION...Increasing likelihood of respiratory symptoms
in sensitive individuals, aggravation of heart or lung disease and
premature mortality in people with cardiopulmonary disease and
older adults. People with heart or lung disease, older adults, and
children should reduce prolonged or heavy exertion.
