‘Don’t Light Tonight’ Season Has Begun

NOVEMBER 1, 2016 — The Yolo-Solano Air Quality Management District (AQMD) today announced that it has launched its 2016-17 Don’t Light Tonight season on Tuesday, November 1.

Smoke from the use of fireplaces and woodstoves is a major source of local wintertime air pollution. Yolo-Solano AQMD issues Don’t Light Tonight advisories when weather conditions are forecast to trap wood smoke near ground level where it is breathed by residents.

When a Don’t Light Tonight advisory is in effect, residents should refrain from burning wood. Wood smoke and other fine particulate pollution is most dangerous to young children and the elderly and causes asthma attacks and other respiratory symptoms.

“We can all help protect clean air this winter by heeding Don’t Light Tonight advisories,” said Mat Ehrhardt, Yolo-Solano AQMD’s executive director. “Wood smoke impacts the health of your family and neighbors. By choosing not to burn when advisories are in effect, you’re making a difference.”

Yolo-Solano AQMD has a network of air monitors around the region that measure pollution concentrations. Local air quality was unhealthy for sensitive groups did not exceed the federal health standard for fine particulate pollution during the 2015-16 winter season. Twenty Don’t Light Tonight were called.

Yolo-Solano AQMD does not issue citations for compliant wood burning as the advisories are voluntary. Don’t Light Tonight advisories apply to all of Yolo County and the northeastern portion of Solano County including Dixon, Rio Vista and Vacaville.

Residents concerned with smoke in their neighborhood should contact Yolo-Solano AQMD at (530) 757-3650.

The easiest way to be notified about Don’t Light Tonight advisories is to sign up for EnviroFlash alerts. You will be sent an email or text message when an advisory has been called for the next day. Sign up at

You can also call the Don’t Light Tonight hotline at (530) 757-3787 to find out daily status. Yolo-Solano AQMD will also post any advisories on its Facebook page at
