SF Muni continues to run on diesel, despite deadline

Although the MUNI transportation system in San Francisco does a wonderful job of getting polluting cars off the street, when it comes to managing its own polluting fleet, it comes up short:

Disappointing environmentalists and public health advocates, San Francisco's Municipal Railway has missed the first of three deadlines to phase out about 150 highly polluting diesel buses.

The first deadline, mandated by last year's voter-approved Proposition I, expired last month and required Muni to replace a quarter of the buses. The Board of Supervisors' land use committee will hold a hearing on Wednesday to examine how the transit agency is complying with the terms of Prop. I.
