LOS ANGELES --- Airport commissioners have approved the purchase of 30 alternative-fuel buses and trucks for use at Los Angeles International Airport (LAX) as part of the ongoing effort to replace gasoline-powered vehicles in the airport's fleet with alternative-fuel vehicles. The airport 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 $7,885,648 from North American Bus Industries. Reynolds Buick Pontiac GMC Trucks will provide the refuse trucks at $265,337 and the stakebed trucks at $383,228. Officials at Los Angeles World Airports (LAWA), the city department that owns and operates LAX and three other Southern California airports, have said that plans are underway 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.
