California Environmental Reporting System

The California Environmental Reporting System (CERS) is a statewide web-based system to support California Unified Program Agencies like Environmental Health in electronically collecting and reporting various hazardous material-related data as mandated by Section 25404(e)(2-5) of the California Health and Safety Code and 2008 Legislation (AB 2286).

This includes businesses that:

  • Handle or store hazardous materials
  • Generate or treat hazardous waste
  • Own or operate underground storage tanks
  • Are part of the California Accidental Release Prevention Program
  • Store 1,320 gallons or more of petroleum in aboveground tanks

Additional Documents

When submitting the Hazardous Materials Management Plan (HMMP) through CERS, a few of the submittal elements such as facility site maps, emergency response/contingency plans and several underground storage tank program information forms are separate documents that must be completed and uploaded to the CERS site. Links to suggested document template forms can be found on the CERS site or on the specific program page(s) for Hazardous Materials & Waste and Hazardous Material Management Plan.
