By boosting efforts to detect and repair excessively polluting motor vehicles, the Smog Check II program is expected to reduce the total volume of smog-forming emissions from California's motor vehicles by about 100 tons per day this can be compared to the amount of ozone-forming emissions that is produced by californias power plants ------------------------------------------------------------------------ **Bibliography**
