California Air Resources Board

Air pollution complaints from the public are an important tool to help identify noncompliance with air quality regulations and community concerns. Enforcement staff receives complaints from the public by phone, email, and online reporting. Complaints that fall under CARB’s authority are referred internally for investigation and those that fall under local jurisdiction are referred to the local air districts for investigation. Enforcement staff documents CARB’s and air districts’ investigations and findings. When appropriate, Enforcement staff may participate in complaint investigations with air district staff. For complaints that are not related to air pollution, staff work with the reporting party to ensure the complaint is routed to the proper regulatory agency for investigation and resolution.
