Report an Air Pollution Complaint

Air quality complaints may be reported online or by phone. The Air District will keep the complainant's personal information confidential, such as name, address, and telephone number, to the fullest extent permitted by law. Members of the public may also choose to report complaints anonymously.

When reporting an air quality complaint, provide as much information as possible. Providing detailed descriptions of the complaint can better help the Air District inspector locate the source of emissions and identify compliance concerns or violations of air quality regulations.

Accessibility and Non-Discrimination Provision

From time to time, the Air District may receive an air quality complaint in which the complainant states that they believe they or others were denied full and equal access to an Air District program or activity because of a protected status, including those identified in the Air District’s Accessibility and Non-Discrimination Policy, which prohibits discrimination on the basis of race, national origin, ethnic group identification, ancestry, religion, age, sex, sexual orientation, gender identity, gender expression, color, genetic information, medical condition, or mental or physical disability, and other protected statuses.

Air District staff who receive or investigate such a complaint shall promptly notify their manager of the allegation and the manager shall refer the complaint to the Air District Non-Discrimination Coordinator.
