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 13 to 400 PM Friday August 14
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 14, 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 Friday afternoon across the 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 Fort Collins, including areas
west of I-25 within the lower foothills on Thursday and Friday.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
