What is an Air District?

An Air District is one of 35 local regulatory agencies in California responsible for ambient (outdoor) air quality in its geographic region. Air Districts are a form of local government, created by state law and separate from county and city government.

An Air District carries out local, state and federal air quality programs which includes air monitoring, stationary source permitting, open burn permitting, performing compliance inspections, administrating grants, and responding to air quality complaints.

In 1955 the Bay Area Air Quality Management District (BAAQMD) was formed and was originally comprised of the urban counties of Alameda, Contra Costa, Marin, San Francisco, San Mateo and Santa Clara counties. Sonoma County was included as an “inactive” member at that time. In 1971 the southern portion of Sonoma County joined the BAAQMD as an active member and the northern portion of the county was established as its own Air District, The Northern Sonoma County Air Pollution Control District, primarily because of its rural nature.

The District border is complex and does not follow roads or other geo-political features. To verify if you are in our District, go to the map application on our home page and type your address into the map. It will determine if you are located in the Northern Sonoma County Air Pollution Control District or in the Bay Area Air Quality Management District (BAAQMD).

Yes, if you are in the NSCAPCD territory. “Spare the Air” is a regulation of the BAAQMD in effect from November through February that prohibits the burning of wood in woodstoves and fireplaces on days that are forecast to have poor air quality. Our District does not implement “Spare the Air Day” at this time as we do not have this regulation, and our District is in compliance with all state and federal ambienT air quality standards.

Yes. Any wood burning appliance installed, or that transfers appliance ownership in the District must be an EPA certified wood burning device. A building permit is also required from the County of Sonoma that also requires EPA certification for installation.

Vehicles registered to addresses located within the District are exempt from the bi-annual SMOG check program. Use the map application on our home page to verify you are in the District. Vehicles brought into the District from another area typically require an initial smog check. There are some addresses that are located along the District border, namely in northern Sebastopol and Sonoma County addresses listed as Calistoga, which may trigger a smog check notification from DMV. If you are located in one of these areas you may contact the District to have a “Smog check exemption” letter printed stating that vehicles registered to an address in the Northern Sonoma County APCD are exempt from the Smog check program. The letter can be taken to a DMV office to verify that the vehicle is exempt from the smog inspection program. Please call 707-433-5911 to determine if you qualify for an exemption.

Yes, with a valid District burn permit, on a permissive burn day, following all of your permit’s requirements. Only dried vegetative matter generated on the property may be burned on a permissive burn day. No open burning is allowed on a District designated “No Burn Day”. Requirements on how to carry out a compliant open burn are listed on the burn permit, including the phone number one needs to call to determine if it’s a permissive burn day. Barrel burning is always prohibited by state law. Burn permit information, including the ability to pay online for a burn permit, is listed on our Burn Permit page.

It depends on the type of building. The District implements the federal National Emission Standard for Hazardous Air Pollutants (NESHAP) for asbestos.

If your facility has a piece of equipment or process that emits to the atmosphere an air contaminant (something other than water vapor), you might, depending on how much it emits.
