Our regional offices evaluate air quality trends year-round to address and forecast pollutant levels, smoke events, and other weather-related issues that affect local communities. These efforts are based on a variety of factors such as, but not limited, to topography, emission sources, and residential heating practices.
The Treasure Valley is the largest and most highly populated urban area in Idaho and a significant percentage of the state’s industry and business.
Due to topography and weather patterns, the area is subject to inversions in the winter and ozone and wildfire pollution in the summer. Air quality improvement plans have been implemented to address carbon monoxide and particulate pollution.
