Everyone deserves to breathe fresh air. In Northern Sonoma County, we’re surrounded by vineyards and farms, with plenty of open space to explore. We’re lucky to work and play outside most of the year. That’s why clean air is so important.
At the Northern Sonoma County Air Pollution Control District (NoSoCo Air), we’re responsible for regulating the air quality in our region. We’re proud to help ensure our environment remains healthy, beautiful, and sustainable.

There are two Air Districts in Sonoma County. Find out if you’re part of NoSoCo Air.
