The graphic above shows expected air quality conditions for the Denver metro area. During the winter high pollution season (November through March) the graphic indicates whether an air quality Action Day is currently in effect. During an air quality Action Day, indoor burning is restricted in the seven-county Denver-metro area, including Denver, Boulder, Broomfield, Douglas, Jefferson, and areas west of Kiowa Creek in Adams and Arapahoe counties. The only exceptions to the indoor restrictions are for people living above 7,000 feet; those who use Phase II EPA certified stoves, Colorado approved pellet stoves, approved masonry heaters or those whose stoves or fireplaces are their primary source of heat. For more information on indoor restrictions follow the links below.
Residents are also asked to voluntarily limit driving on Action Days.
On days that are not air quality Action Days, no restrictions are in place.
