Air Quality Alert

Boulder-Weld-Adams-Denver-Jefferson-Douglas-Arapahoe-

910 AM MDT Thu Aug 13 2020

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

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 Wednesday August 12 to 400 PM Thursday August 13

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. Thursday, August 13, 2020.  Due to wildfire smoke
transported into the Front Range, Ozone and Fine Particulate
concentrations could both reach the Unhealthy for Sensitive Groups
category at times through Thursday afternoon across the northern
Colorado Front Range region. The greatest air quality impacts are
expected to be for locations within the Denver Metro area, as well
as northward along the I-25 corridor to Longmont, including areas
west of I-25 within the lower foothills.  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.
