Hazardous Materials (CUPA)
Certified Unified Program Agency (CUPA)
The Unified Hazardous Waste and Hazardous Materials Management Regulatory Program (Unified Program) was established in 1993 to protect public health and safety, and to restore and enhance environmental quality, and sustain economic vitality through an effective and efficient implementation of the Unified Program. San Mateo County Environmental Health Services was designated by the State Secretary for Environmental Protection as the Certified Unified Program Agency (CUPA) for San Mateo County in 1996.
Compliance is achieved through routine inspections of regulated facilities, and investigation of citizen-based complaints and inquiries regarding improper handling and/or disposal of hazardous materials and/or hazardous wastes.
If your facility needs to be regulated for any of the CUPA programs listed below, you need to obtain a permit by registering your facility with San Mateo County Environmental Health Services. Please contact the designated district inspector for assistance with the registration process.
A complete list of active and inactive hazardous waste (CUPA) regulated facilities is now available on the County’s Open Data site. The list is updated monthly. Site-specific information can be found on the State’s Regulated Site Portal. This site includes activities related to hazardous materials and waste, state and federal cleanups, impacted ground and surface waters, and toxic materials. It is maintained by the California Environmental Protection Agency and the information is updated monthly. On this site, you will find information about regulated facilities, chemical storage, open violations. If you would like additional details about a particular facility, please make a file review request.
