Los Angeles County Supervisor Don Knabe helped to retire Metro's last running diesel-fueled bus on Jan. 12. "Today is a great day for Metro and the people of L.A. County because it's an excellent day for our region's air quality," said Knabe, who chairs the Metro board of directors. "With today's retirement, Metro becomes the first major transit system in the world to run entirely on clean alternative fuels. We've been working toward this day since 1993 and now just one look at our sky helps tell the story. The air is getting cleaner, in part because Metro is getting greener." ********** Published: January 13, 2011 - Volume 9 - Issue 39
