Idaho DEQ Air Quality Forecast and Caution

DEQ extends statewide air quality advisory

Friday, August 21, 2015

BOISE — Continuing smoke impacts from wildfires have prompted the Idaho Department of Environmental Quality (DEQ) to extend a statewide air quality advisory over the weekend.

This advisory is in effect until 2:00 pm on Monday, August 24, at which time conditions will be evaluated again on a county‑by‑county basis. This advisory does not apply to lands within Indian reservation boundaries or to activities associated with fire suppression.

“Air quality remains in the Moderate to Unhealthy categories throughout most of the state. Although changing weather may bring intermittent periods of clearing, significant clearing of smoke is not forecast to occur over the next couple of days,” said DEQ’s Smoke Management Program Coordinator Morrie Lewis.

Under this advisory, all open burning is prohibited, including campfires, recreational fires, weed control burning, and residential burning.

Daily updates on air quality conditions at various locations in Idaho are available on DEQ's Air Quality Reports and Forecasts and Current Wildfire Smoke Information webpages. For areas where air quality monitors are not available, the Visibility Range and AQI Table can help determine the necessary precautions to take.

DEQ is extending an Air Quality Forecast & Caution Date/Time Issued: Friday, August 21, 2015/1:00 p.m. Next Update: Monday, August 24, 2015/2:00 p.m.

Due to widespread wildfire smoke impacts, the Idaho Department of Environmental Quality (DEQ) has issued an Air Quality Forecast and Caution to notify residents of the state of Idaho outside of reservation boundaries of degraded air quality.  Air quality is currently within theMODERATE to UNHEALTHY categories and is forecast to remain that way over the next couple of days. The pollutant of concern is Fine Particulate Matter (PM2.5).

Air Quality Index (AQI):

Range Category Meaning 0 to 50 Good Air quality is considered satisfactory, and air pollution poses little or no risk 51 to 100 Moderate Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution. 101 to 150 Unhealthy for Sensitive Groups Members of sensitive groups may experience health effects. The general public is not likely to be affected. 151 to 200 Unhealthy Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects. 201 to 300 Very Unhealthy Health warnings of emergency conditions. The entire population is more likely to be affected. 301 to 500 Hazardous Health alert: everyone may experience more serious health effects.
