Spare the Air in the San Francisco Bay Area

 Winter Spare the Air logo

The 2018/2019 Winter Spare the Air season runs from November 1 through February 28.

When air quality is forecast to be unhealthy, the Air District will issue a Winter Spare the Air Alert.

When a Winter Spare the Air Alert is in effect, it is illegal to burn wood, manufactured fire logs, pellets, or any other solid fuels in your fireplace, woodstove or outdoor fire pit.

During the winter season, wood smoke is the largest source of harmful particulate pollution. On this website, residents can find information about the health effects of wood smoke, as well as detailed information about the Wood Burning Rule and how to comply with it. Here are answers to some Frequently Asked Questions about the Winter Spare the Air program.

You can also file a wood smoke complaint online.

It’s Your Air. Protect It.
