LOS ANGELES — On Nov. 15, the L.A. County Board of Supervisors voted unanimously on a motion by Supervisor Zev Yaroslavsky to adopt the policy of making hybrid vehicles the primary choice when replacing or acquiring sedans and light-duty trucks within the county’s fleet of approximately 15,000 vehicles. This follows the recently signed California Assembly bill AB1660 (Vehicular Air Pollution: Alternative Fuel Vehicle Purchasing Program) that provides for a “High Polluter Repair or Removal Program.” It is anticipated that this policy will assist the county in realizing substantial savings on fuel costs, as well as substantial improvement in the air quality of Los Angeles County, according to Randy Martin, fleet manager for the Internal Services Department for the county of Los Angeles.
