How to file a Complaint

If you believe that the situation is a fire endangerment issue, call your local fire department or dial 911. The Air District does not put out fires. 

In general, the quickest way to submit an air quality complaint to the District is to call (209) 533 -5691. If you call outside of regular business hours or on the weekend please leave a detailed message or you may submit your complaint via online here.

The District will log the complaint, assign it to an inspector who will then initiate an investigation within 24 hours of receipt of the complaint. Response time is  contingent upon current business hours and staff availability. 

When you call, please have the following information ready:

  • A specific description of the problem. Is it odor, smoke, or dust?
  • The location of the problem including address and cross streets.
  • If known, who is causing the issue?
  • The time, time of day and frequency the issue occurs.

The information submitted will be processed during regular business hours. Complainant information is always kept confidential.
