Air Quality Alert

COC013-123-001-031-059-035-005-014-069-282200-
Boulder-Weld-Adams-Denver-Jefferson-Douglas-Arapahoe-
Broomfield-Larimer-
910 AM MDT Mon Sep 28 2020

...ACTION DAY FOR PARTICULATES FROM 400 PM SUNDAY UNTIL 400 PM
MONDAY...

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

WHAT...Action Day for Particulates.

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

WHEN...400 PM Sunday September 27 to 400 PM Monday September 28

IMPACTS...Action Day for Particulates is now in effect for the
seven-county Denver-Boulder metropolitan area. Requests to limit
driving of non- ZEV vehicles (i.e., gas or diesel) are now in
effect until at least 4 PM Monday, September 28, 2020.  Decreased
activity at local wildfires has resulted in much improved air
quality for most of the Front Range region. However, parts of
central and western Larimer and Boulder Counties could still see
periods of brief to heavy smoke through Monday afternoon due to
their proximity to the Mullen and Cameron Peak wildfires.  For
areas included in this advisory that are not expected to exceed
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...If smoke is thick or becomes thick in your
neighborhood you may want to remain indoors. This is especially
true for those with heart disease, respiratory illnesses, the very
young, and the elderly. Consider limiting outdoor activity when
moderate to heavy smoke is present. Consider relocating
temporarily if smoke is present indoors and is making you ill. If
visibility is less than 5 miles in smoke in your neighborhood,
smoke has reached levels that are unhealthy.
