Q. Once I have my burn permit can I burn whenever I want?

A. No. You must call (602) 506-6010 to gain permission from Air Quality to ensure that you aren't burning during a high pollution advisory. And you must call the local fire department for permission. This is done in case a citizen sees and calls to report smoke, the fire department won't respond to a permitted burn.

Fire department denials could happen during very windy days or when fire trucks are down or when fire personnel staffing can't support a fire that could become out of control in which case the fire department might ask you to reschedule. Fires are only to be maintained during day light hours. All fires must be out by dark.
