Northwest Clean Air Agency

Northwest Clean Air Agency Working to protect and improve air quality in Washington's Island, San Juan, Skagit, and Whatcom counties.

Since the passage of the Washington State Clean Air Act in 1967, the Northwest Clean Air Agency has been the primary government agency responsible for protecting the air in Island, Skagit and Whatcom counties. We are responsible for enforcing federal, state and local air quality regulations at stationary sources of air pollution in our jurisdiction. In addition to regulating businesses, we focus on informing the public about air quality issues and how to make clean air choices.

NWCAA AQ FORECAST: Expect Good air quality this holiday weekend for Island, San Juan, Skagit, and Whatcom counties, as wind and rain will continue to help keep the air clean.

Extreme eastern portions of Whatcom County will be in the Moderate to Unhealthy range due to wildfire smoke from the nearby Border 2 and Luna fires.

Recent rain and fire suppression efforts have brought containment of the Little Giant Fire north of Leavenworth to 73%. This, along with weather conditions limiting fire growth, has led to a dramatic reduction in smoke production from the fire in recent days.

There may still be periods of elevated haze this weekend due to wildfire smoke, but impacts are expected to be minor.
