Data Request / "FOIA" Request
The public can request to view public information in writing, verbally, by fax or by e-mail. Written requests should be identified as a request for public information under the Public Records Act and directed to the Air District Clerk of the Board. Written requests should be mailed to Northern Sonoma County Air Pollution Control District, 150 Matheson Street, Healdsburg, CA 94558. The written request need not be in any particular form, but should describe the requested records with sufficient detail to enable District Staff to identify and locate the information sought. To the greatest possible extent, please include permit numbers, company and/or individual names, street addresses, names, descriptions and dates of correspondence, reports, submittals, and similar information so that the District may respond to your request. The request must also contain an address, phone number, and/or e-mail address so the District can reach you. To help assure that your request contains information enabling a prompt response, you may use the online form for Air Pollution Public Record & Information Requests.
The Public Records Act requires the District to respond to requests for public information within 10 days. The response will tell you whether the information you request is available, how you can view it or get copies, the cost of providing the copies, which (if any) of the records are not subject to disclosure (see below, Public Records Exempt from Disclosure), and how to make an appointment, if needed.
Public records are open to inspection during District office hours, 8:00 AM - 4:30 PM, Monday through Friday, except for state and District holidays or mandatory furlough days. However, for the most efficient processing, the District requests that you make an appointment so District Staff can have the records available and provide space for you to review them.
