School Bus Idle Reduction Regulations
Beginning July 1, 2008, the State Board of Education is required to implement an idle reduction program for all school bus drivers in the state and adopt idle reduction standards. The Board of Education will consult with local school districts and the Utah Air Quality Board regarding program and standard development. (Reference House Bill 146, 2008, and Utah Code 41-6a-1308)
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. These regulations include idling restrictions for diesel vehicles. Specifically, an owner or operator of a diesel powered vehicle is not allowed to have the vehicle idle 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)
