Reporting Odors and Emissions and other Air Contaminants

The San Diego County Air Pollution Control District monitors and investigates air quality complaints about the emissions of air contaminants – including smoke, dust and odors – which have the potential to cause injury, nuisance or annoyance. The APCD commonly investigates improper asbestos removal, gasoline dispenser nozzle problem, unpermitted equipment and operation, and illegal burning in addition to smoke, dust, and odors.

Complaint information is forwarded to a District inspector as soon as possible for investigation and resolution. However, complaints received outside of normal business hours (M-F, 8 AM-5 PM) may be investigated the next business day. If a business is in violation of any air quality rules or regulations, the District may issue a Notice of Violation. If a Notice of Violation is issued, the business must take action to correct the violation and may pay a monetary penalty to the District.

When an air quality problem is observed at a stationary source, call 858-586-2650 or email You can also submit complaints using the Tell Us Now app (available for download for mobile devices).
