7:25 AM SEPTA bus idling at curbside. I believe the bus # was 5762 (but I did not jot the number down today). SEPTA idling at this location is a recurrent issue. This suggests that SEPTA is either unable or unwilling to enforce rules upon their drivers. It would be helpful to know if any other authorities have taken steps to enfore anti-idling rules. The recommendation has been made to call Air Management, but their phone goes to voicemail when I have tried calling in the early AM.
