Ozone Planning

The Air Quality Program’s goal is to remain in attainment (compliance) with EPA's National Ambient Air Quality Standard for ozone.

The Air Quality Program's Ozone Reduction Initiative includes:

Vehicle owners can help reduce ground-level ozone by following these tips:

  • Refuel your vehicle during the coolest times of day
  • Maintain proper tire pressure to boost your car's performance and our air quality
  • Turn off your engine instead of idling to save gas and reduces emissions
  • Bike, carpool, or use public transit to reduce emissions from vehicles

Ways to limit your exposure to ground-level ozone:

  • Exercise indoors or early in the day when ozone levels are lowest. As the day progresses and the temperature rises, ozone levels also get higher.
  • Stay away from high-traffic areas. Don’t walk, jog, or cycle along the freeway or places where cars tend to idle.
  • Use ozone-reducing air filters indoors to control the ozone entering your home.
