Air Quality Requirements

All Contractors are required to comply with The Moscone Center Air Quality Program designed to achieve clean air operating goals established by the City & County of San Francisco.


Compliance includes the installation of catalytic converters on all motorized vehicles, monitoring of gasoline and diesel vehicles, installation of “Clean Air Catalyst” units on all contractor-owned or operated diesel tractors as of 7/1/02, and other approved methods of air quality control.


All vehicles not in compliance with specified operating limits will be removed from The Moscone Center immediately. Please contact Moscone Management for specific details of the program.
