Regarding Smoke from Clarksburg Traveling into Sacramento

We apologize for the smoke that impacted so many communities and residents in the Sacramento region. Yesterday the District approved an ag burn in Clarksburg that the farmer lost control of and as a result sent smoke into the air and through the valley.

District staff were on site last night and are there this morning doing an active investigation, working hard to resolve this issue. The fire is out but continues to smolder and emit smoke. The smoke will linger through the day and should hopefully disperse with the aid of the delta breeze.

We recommend reducing exposure to the smoke by staying indoors and reducing outdoor heavy exertion.

We appreciate the concern from residents and again we apologize for the smoke impacts and are working to get this resolved.

Third Consecutive Day of Spare The Air Issued

(Davis, CA) – A third consecutive Spare The Air alert has been issued for the greater Sacramento region for Thursday, August 3, 2017 with the AQI for ground-level ozone pollution expected to reach 126 or higher, which is unhealthy for sensitive groups. This is the 11th Spare The Air issued for the season so far.

High temperatures combined with stagnant air conditions and a ridge of high pressure contributed to the initial Spare The Air alert on Tuesday, August 1. The ridge of high pressure continued to sit in place Wednesday while light winds and lingering smoke from several wildfires in Northern California contributed to the poor air quality.

Those sensitive to air quality, such as young children, the elderly, women who are pregnant, and people with heart or lung disease and asthma should limit their outdoor activity. To help reduce smog, residents are asked to drive less. Carpooling, riding transit, telecommuting, trip-linking, bicycling and walking are excellent ways to reduce driving.

This alert includes the air districts in Placer, Feather River, El Dorado, Sacramento Metropolitan and Yolo-Solano. The Yolo-Solano Air Quality Management District supports all of Yolo County and portions of Solano County that include Dixon, Vacaville and Rio Vista.

Spare The Air is an educational and advisory program that runs every year from May to October in the greater Sacramento region.
