Reduce Wood Smoke in Our Region
Each county in the Sacramento region has its own program for dealing with wood smoke pollution.

Check Before You Burn is the Sacramento Metropolitan AQMD's law that restricts or prohibits wood burning in Sacramento County and its cities of Citrus Heights, Elk Grove, Folsom, Galt, Isleton, Rancho Cordova and Sacramento when PM2.5 pollution is forecast to be unhealthy to breathe - Check Before You Burn

Check Before You Burn season is in effect. Thank you for not burning. Your compliance on no-burn days reduces pollution and positively impacts the health of our residents.

Yolo-Solano AQMD issues voluntary Don't Light Tonight advisories for Yolo County and northeastern Solano County. For information on wood smoke and fireplaces in Placer and El Dorado counties, please visit their websites: Placer County APCD and El Dorado County AQMD.

Air Quality Forecast and Weather Discussion
Sunday, moderate north-northwesterly winds through the midday hours will effectively disperse pollutants in the Sacramento area. Therefore, despite light southeasterly winds in the afternoon and evening limiting mixing, particle levels will be low-Moderate. Monday and Tuesday, an upper-level ridge of high pressure will build over northern California, reducing atmospheric mixing. In addition, calm to light winds will inhibit dispersion, and temperature inversions each night will trap pollutants near the ground. Furthermore, pollutant carryover from day to day will be high. As a result, particle levels will be high-Moderate on Monday and Unhealthy for Sensitive Groups on Tuesday.
