Regulations for Solid Fuel Burning Devices

These regulations cover Box Elder, Cache, Davis, Salt Lake, Tooele, Utah, and Weber Counties and include fireplaces and wood, pellet, and coal burning stoves.

Winter inversions trap microscopic particles called PM2.5 in the air. The use of solid fuel burning devices, such as fireplaces wood, pellet, and coal burning stoves contributes PM2.5 emissions to the atmosphere. Winter inversions cannot be controlled, so PM2.5 emissions must be reduced during inversion periods to meet National Ambient Air Quality Standards (NAAQS).

The Division of Air Quality operates air monitoring equipment to measure the concentration of PM2.5 in the atmosphere. This information, with weather forecasting and computer modeling is used to determine the action level for solid fuel burning devices. The following chart explains the three action levels.

Wood Burn Action Level

Unrestricted Action

Wood, pellet and coal burning stoves and fireplaces may be used but please use them in a proper manner to reduce smoke emissions.

Voluntary Action

Voluntarily do not use wood, pellet, coal burning stoves or fireplaces. Reduce vehicle use by consolidating trips. Industry should optimize operations to minimize air pollution emissions.

Mandatory Action

Wood, pellet and coal burning stoves or fireplaces must not be used. Reduce vehicle use by consolidating trips. Industry should optimize operating conditions to minimize air pollution emissions.

MapThe three action levels affect all residents living in the following areas:

  • All regions of Salt Lake and Davis counties.
  • All portions of the Cache Valley.
  • All regions in Weber and Utah counties west of the Wasatch mountain range.
  • In Box Elder County, from the Wasatch mountain range west to the Promontory mountain range and south of Portage.
  • In Tooele County, from the northernmost part of the Oquirrh mountain range to the northern most part of the Stansbury mountain range and north of Route 199.

The current action level is reported twice daily to local media outlets (newspapers, TV, and radio stations). You can also find the action level on our Website and register to receive Email air quality alerts.
