Fire Pits, and Chimineas During the Holidays
What is a No Burn Day? When air pollution levels are on the
rise and weather conditions create dry, stagnant air, the
Maricopa County Air Quality Department will issue a "No Burn
Day." Restrictions last for a 24-hour period, starting at
midnight, and include a ban on woodburning activity including
fireplaces, fire pits or open outdoor fires.
The purpose of the No Burn Day restriction is to avoid adding
pollution to our air when the forecast suggests air quality will
approach or exceed the federal health standard. Learn more at
Fireplaces and Winter Air and
Residential Wood-Burning Q&A.
