The Arizona Department of Environmental Quality (ADEQ) has announced a High Pollution Advisory (HPA) for December 19 and 20, due to expected elevated levels of particulate matter 2.5 (PM2.5), commonly known as soot, in Maricopa County. This advisory is issued when pollutant levels are anticipated to surpass federal health standards.

The Maricopa County Air Quality Department (MCAQD) has implemented a "No Burn Day" policy for the county during the advisory period. As part of this, restrictions include prohibiting wood burning in residential fireplaces and outdoor fire pits, banning leaf blowers on government properties, and disallowing off-road vehicle use.

Individuals with heart or lung conditions, older adults, and children may experience adverse effects from PM2.5 exposure. Such particles can penetrate deeply into the respiratory system causing irritation and exacerbating existing health issues like asthma and heart disease.

Employers are urged to activate their HPA Plans immediately. ADEQ advises the public to minimize outdoor activities during the advisory period, particularly those with respiratory concerns.

To mitigate air pollution, residents and employers are encouraged to visit Maricopa.gov/AQ for more information on reducing emissions, utilize carpooling or public transportation options through ShareTheRide.com, and avoid dust-generating activities such as driving on unpaved roads.

PM2.5 originates from various sources including motor vehicles, industrial processes, power generation, and residential heating appliances like wood stoves.
