    About This Site

    Complyrpedia is the knowledge base for businesses that are required to comply with California environmental regulations

California Environmental Reporting System (CERS)


The California Environmental Reporting System (CERS) is a statewide database. It consolidates hazardous material data and gives emergency managers access to improve emergency response.
From the CERS website:
The California Environmental Reporting System (CERS) is the statewide web-based system that supports the electronic exchange of required Unified Program information among businesses, local governments and the U.S. EPA. Assembly Bill 2286 (Feuer), effective January 1, 2009, requires all Unified Program regulated businesses and local regulating Unified Program Agencies (UPAs), to report and submit mandatory Unified Program information electronically, through CERS or a local UPA portal.
Unified Program information required to be submitted and reported electronically to CERS includes, but is not limited to facility data regarding hazardous material regulatory activities (such as, hazardous materials business plans, site maps, and chemical inventories), underground and above ground storage tanks, hazardous waste generation, and inspection, compliance and enforcement actions. Additional information regarding CERS electronic reporting requirements can be found at:

What to expect during an inspection

The CERS inspection mostly happens at the office of your inspector. The inspector will review your submissions to make sure they have been renewed annually and that they are complete. The inspector might conduct a site inspection to verify the accuracy of your submission. It is not uncommon to have a submission rejected for any one of a number of reasons.
