CONCORD -- Poor air quality will waft into the new year as the 24th "Spare the Air" alert was issued for Wednesday.

The Bay Area Air Quality Management District has banned wood burning both indoors and outdoors on Jan. 1, making it illegal to burn wood, manufactured fire logs or solid fuels for 24 hours.

This wood-burning ban will be in effect for Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, southern Sonoma and southwestern Solano counties.

First-time violators of the ban may be subject to a $100 fine or be given the option of taking a wood smoke awareness class. Subsequent violations will result in fines of $500 or more.

The Winter Spare the Air season lasts until Feb. 28.
