The Los Angeles Board of Airport Commissioners has approved the purchase of 30 alternative-fuel buses and trucks for use at Los Angeles International Airport (LAX).

Airport officials said the purchase is part of the board’s ongoing commitment to replace existing gasoline-powered vehicles in the airport’s fleet with alternative-fuel vehicles when they reach the end of their useful service life.

The board approved the purchase of 21 compressed natural-gas transit buses; three liquefied-petroleum-gas (LPG), light- and medium-duty refuse trucks; and six LPG stakebed trucks.

The 21 buses will be purchased for $7.9 million from North American Bus Industries, Inc.

Reynolds Buick Pontiac GMC Trucks, Inc. will provide the refuse trucks at $265,000 and the stakebed trucks at $383,000.

Officials at Los Angeles World Airports (LAWA), the city department that owns and operates LAX and three other Southern California airports, believe that alternative-fuel vehicles are important elements in meeting California’s future energy needs and said plans are under way to convert all of LAWA’s fleet to alternative-fuel use.

LAWA currently has more than 500 alternative-fuel vehicles in its fleet powered by liquefied natural gas, liquefied petroleum gas, compressed natural gas, electric, solar power and hydrogen fuel cell.
