Spare the Air in the San Francisco Bay Area

brown logo

The 2016/2017 Winter Spare the Air season runs from November 1 through February 28. 

Each day by early afternoon, the Air District will issue an air quality forecast for the next day. If air quality is forecast to be unhealthy, a Winter Spare the Air Alert will be called. The alert will be in effect the entire next day, for a full 24 hours.

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.
