The Arizona Department of Environmental Quality (ADEQ) has activated an Ozone High Pollution Advisory for Maricopa County, set for today, until tomorrow. According to the advisory, ozone levels are expected to climb high enough to surpass the federally designated health standard for ozone.

Ozone at ground level is created when various emissions from vehicles, operational equipment, and industrial processes react with sunlight. Notably, due to the increased intensity of sunlight during the warmer months, ozone pollution often spikes in the spring and summer.

The advisory from the ADEQ indicates that while some individuals may be more susceptible, all residents of Maricopa County could experience adverse effects from heightened ozone levels, which can harm the respiratory system and provoke asthma episodes. According to Maricopa County Air Quality Department, children, who frequently play outside and whose lungs are still developing, along with adults who have lung diseases, are particularly vulnerable.

The public is urged to minimize time spent outdoors during the High Pollution Advisory, especially those with respiratory conditions. ADEQ and MCAQD have proposed a series of actions that both individuals and businesses can undertake to decrease ozone pollution. Among these recommendations are promoting telework to cut down on traffic, driving less frequently, carpooling where possible, and opting for public transit.

Restrictions accompanying this advisory include a ban on wood burning in residential fireplaces, chimeneas, outdoor fire pits, and any similar venues within Maricopa County. This rule applies to both private individuals and businesses, regardless of whether they possess burn permits for open burning. Additionally, government employees and contractors are prohibited from operating leaf blowers, and residents are encouraged to refrain from using them during the advisory period. The use of off-road vehicles is advised against as well.
