Puget Sound Clean Air Agency

Local air quality affects how we live and breathe. Like the weather, it can change from day to day or even hour to hour.

The Puget Sound Clean Air Agency (PSCAA) reports actual levels of particulate matter (PM), ozone and other common pollutants in the air. PSCAA also provides forecasts so residents can see what today and tomorrow’s air quality might bring; this is especially helpful for those with health conditions impacted by poor air quality.

A key tool in this effort is the Air Quality Index, or AQI. PSCAA, along with other state and local air agencies and the EPA, use the AQI to provide simple information on local air quality, the health concerns for different levels of air pollution, and how all of us can protect health when pollutants reach unhealthy levels.

Get reports from around the Puget Sound area with high levels of air pollution, locations of monitoring sites, and sources of pollution, as well as reports (by pollutant).

The Bellevue Fire Department works closely with PSCAA to help enforce regulations specifically concerning outdoor burning. Small, recreational fires are allowed with restrictions. Open burning is prohibited in Bellevue.
