Special Message

The Idaho Department of Environmental Quality (DEQ), Idaho Department of Lands (IDL), and Idaho Department of Health and Welfare (DHW) are asking the public to refrain from all nonessential open burning activities as communities respond to the spread of the novel coronavirus (COVID-19).

 

To avoid additional health impacts, the public should take standard preventative measures to protect their health from smoke exposure and refrain from residential open burning (tree limbs, leaves, yard trimmings, garden waste) and other nonessential open burning activities (including the use of burn barrels and fire pits) until further notice. If open burning is essential please follow best smoke management practices.

 

Local officials may have already prohibited open burning in your area. Prior to burning, contact your local fire agency to verify open burning is allowed.

 

DEQ, IDL, and DHW encourage the public to use alternative burning options:

  • Lawn mulching — Leave grass clippings on your lawn to add nutrients back into the soil and improve lawn health.
  • Composting — Compost yard waste to recycle organic material and add nutrients back into the soil.
  • Chipping — Add chipped brush, pruning, or wood waste to your compost pile or soil to increase nutrient content.
  • Curbside pickup — Collect and separate yard waste, organic material, and recyclables and set them out for curbside collection. Check with your local government or waste management company for local services.
  • Landfills — Many landfills offer free or reduced fees for yard waste.

 

Before conducting any outdoor burning please contact your local fire district. For more information call the Lewiston Region's AQ Hotline at 208-373-0313.

For more information on Regional Air Quality please visit the Lewiston Region web page.

Note: Advance registration with DEQ is required before conducting crop residue burning on lands other than the five Indian Reservations in Idaho. Visit DEQ's Crop Residue Burning Web Page to see requirements and apply for a permit. Click HERE for Crop Residue Burning Map

This Air Quality forecast represents the expected level of pollution for the area. The forecasted AQI is the average for the entire day. There may be short periods of time throughout the day when air quality is greater or less than the forecasted AQI. The forecast is produced by DEQ staff located in the regional office nearest the area represented.

The AQ Forecast Discussion section describes the weather and other pertinent factors contributing to the air quality condition for the day.
