Report an Air Pollution Complaint

The Air District responds to and investigates all air pollution complaints. Resolving air quality problems is one of the Air District’s highest priorities. 

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.
