Idle Reduction Requirement - Salt Lake City

In order to reduce PM10 air pollution levels, the Salt Lake City-County Board of Health has adopted regulations governing a diesel vehicle emissions inspection and maintenance program, including idling restrictions for diesel vehicles. An owner or operator of a diesel powered vehicle is not permitted to idle the vehicle for more than 15 minutes. Vehicles may be exempt from these restrictions under the following conditions: a) supplying power to a refrigeration unit to cool trailer contents, b) providing heat or air conditioning to a sleeper unit of the vehicle, or c) emergency vehicles. However, exempt vehicles may not idle for more than 15 minutes if located within 500 feet of any residence. (Reference Salt Lake City-County Health Regulation 28)
