Forecast: Forecast Legend

The Action Forecast uses an Unrestricted, Voluntary and Mandatory advisory format to help control solid fuel emission. The Action Forecast is based on Utah Administrative Code: R307-302: Solid Fuel Burning Devices in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah, and Weber Counties. This system is also used to advise industry operations and vehicle drivers.

Action Legend: PM 2.5 | Ozone

Unrestricted Action
Solid fuel burning devices may be used, including wood and coal burning stove and fireplaces, but visible emissions must meet air quality regulations (see R307-302-5). No restrictions, but visible emissions from solid fuel burning devices must meet air quality regulations (see R307-302-5). Individuals are encouraged to limit emissions and choose cleaner transportation options.
Voluntary Action
Individuals are asked to voluntarily not use solid fuel burning devices, including wood and coal burning stove and fireplaces; reduce/stop open burning, and TravelWise by consolidating trips. Industry should optimize operations to minimize air pollution emissions. Individuals are asked to voluntarily TravelWise by consolidating trips and choose cleaner transportation options. Limit volatile organic compound (VOC) emissions.
Mandatory Action
Solid fuel burning devices must not be used, including wood and coal burning stove and fireplaces. Open burning may not occur; including fire pits, fire rings, and campfires. TravelWise by consolidating trips. Industry should optimize operations to minimize air pollution emissions. Employers activate madatory trip reduction programs. Individuals should TravelWise by consolidating trips and choose cleaner transportation options. Limit volatile organic compound (VOC) emissions.

The Health Forecast uses EPA's Air Quality Index (AQI)
