Local Government Contacts

Your local agencies that have jurisdiction over air, water, Certified Unified Program Agencies (CUPA), household hazardous waste, and other local programs are good starting points for information regarding environmental issues. To assist you in finding those contacts, DTSC has linked the county names on the map to documents that contain county-by-county agency listings. Click on the name of a county to get to the local environmental agency list.
