The Arizona Department of Environmental Quality (ADEQ) has issued an Ozone High Pollution Advisory (HPA) for Maricopa County for Monday, July 8, and Tuesday, July 9, 2024. This advisory is due to expected ozone levels that may exceed the federal health standard.

Ground-level ozone forms when emissions from vehicles, gasoline and diesel equipment, industrial processes, and other activities react with sunlight. This type of pollution is more common during spring and summer months. Ground-level ozone can affect all residents but poses a higher risk to children, adults with asthma or other lung diseases, and older adults.

ADEQ and the Maricopa County Air Quality Department (MCAQD) recommend several measures to reduce ozone pollution:

- Promote remote work to reduce traffic.

- Carpool or use public transportation.

- Avoid long drive-thru lines by parking and going inside.

- Ride a bike or walk instead of driving.

- Sweep instead of using leaf blowers.

- Refuel vehicles after dark or during cooler evening hours.

- Use low-VOC or water-based paints and delay painting projects until advisories have passed.

- Ensure household cleaners and chemicals are sealed properly.

Residents can visit Maricopa.gov/AQ for more information on reducing air pollution.

The HPA includes restrictions such as prohibiting wood burning in residential fireplaces and outdoor fire pits in Maricopa County. Government employees are prohibited from operating leaf blowers, and residents are encouraged to avoid their use during HPAs. Off-road vehicle use should also be avoided.
