Saturday, August 11, 2012, is a Spare the Air Day in the San Francisco Bay Area.

Concentrations of ground-level ozone pollution are forecast to be unhealthy. Hot temperatures and light winds will combine to produce poor air quality for the Bay Area.

To help prevent smog, please:

- Carpool or vanpool with friends or co-workers
- Take public transportation
- Telecommute -- work from home instead of driving to work
- Link necessary trips and postpone errands if possible
