  "High Pollution Advisory" or "HPA" means the highest concentration of pollution may exceed the federal health standard. Active children, adults and people with lung disease such as asthma should reduce prolonged or heavy outdoor exertion. Maricopa County employers enlisted in the Travel Reduction Program are asked to activate their HPA plans on high pollution advisory days.

The Arizona Department of Environmental Quality (ADEQ) is issuing a High Pollution Advisory (HPA) for ozone effective September 4, 2020, in the Phoenix area. ADEQ recommends that people limit outdoor activity while the HPA is in effect, especially children and adults with respiratory problems. Ground level ozone forms when two types of pollutants—volatile organic compounds (VOCs) and nitrogen oxides (NOx)—react in sunlight. These pollutants come primarily from automobiles, but also from other sources including industries, power plants, and products, such as solvents and paints. Generally, the highest levels of ozone occur in the afternoon.
