In 1987, the Board of Supervisors passed legislation urging Muni “to take certain steps to minimize air pollutant emissions,” and get workers trained “in the latest emissions reduction techniques.”

Fine words. But, in 1996, representatives from the San Francisco budget analyst’s office staked out bus yards in the wee hours, and observed Muni employees idling diesel coaches for up to four-and-a-half hours; “Pollution Menace at Muni, Audit Finds,” screamed the eventual front-page headline in the San Francisco Examiner.  That story revealed the city analysts’ grim tabulation of Muni’s dirty habit: Those idling buses needlessly discharged the equivalent amount of pollutants as 56,000 cars—every single day.

In 2013, your humble narrator staggered up to a Muni yard at 4 a.m. and documented that it was all still happening. The first rays of sunlight revealed an oily haze enveloping the yard—the byproduct of scores of buses idling for hours on end.

Idling a bus for more than five or 10 minutes, by the way, is not only wasteful and unnecessary, but is also a violation of state law

Idling buses for hours—damaging their engines, wasting money and fuel, and polluting the environment—has been a problem at Muni for decades. And, a few months ago, the phone calls started coming in: It’s still happening…

Muni has long idled its buses indefinitely, and, barring decisive action, will continue to do so indefinitely. It does so despite the explicit instructions of the manufacturer of its diesel engines, and against the recommendation of every vehicle manufacturer on God’s green earth. It does so in the face of economic, mechanical, and environmental rationales and in violation of common sense and common decency.
