What is a Smog Watch?
A Smog Watch is a call-to-action issued by the Clean Air Agency to encourage individuals and businesses to reduce their smog-producing activities during summer hot spells. By issuing a Smog Watch, we help protect public health and ensure the region does not exceed the federal health standard for ozone.
A Smog Watch is issued when agency meteorologists predict elevated smog levels within the next 48 hours and are expected to persist for several days. During a Smog Watch, we encourage people to voluntarily take steps that will keep smog levels from rising even higher.
Don’t get bogged by smog: Here’s what you can do
By adopting some of these permanent behaviors, we can all do our part to reduce smog, and protect our health and our environment:
Drive less – and bus, bike, walk, or carpool more. Cars and trucks typically produce more than 700,000 pounds of smog-forming pollutants on a summer day in Puget Sound region.
Stash the gas mower. Reducing use of gasoline powered yard equipment, or opting for electric or manually powered devices instead, helps keep smog levels down.
Try pollution-free water recreation. Motor boats produce about 85,000 pounds of smog-forming pollutants each summer day in the Puget Sound region – try sailing, canoeing or kayaking instead.
Quit idling around. Idling for longer than 30 seconds actually burns more fuel than turning off and restarting your engine. Turn off your engine instead. You’ll save money too!
Refuel when it’s cool. Refueling your vehicles in cooler evening hours reduces the opportunity for Volatile Organic Compounds released by gasoline to turn into ozone.
