The County of San Diego Department of Environmental Health (DEH), Hazardous Materials Division (HMD) is the local agency responsible for implementing the CalARP Program in San Diego County. The goal of the CalARP Program is to reduce the likelihood and severity of consequences of extremely hazardous materials releases. Examples of extremely hazardous materials (Regulated Substances) include toxic gases such as chlorine, ammonia, sulfur dioxide and other toxic materials. The HMD coordinates with facilities that handle extremely hazardous materials to evaluate the risks of covered processes and require appropriate Risk Management Programs (RMP) at these facilities. A successful RMP includes all of the following elements:  

  • Worst-case release scenario with community effects
  • Hazard Assessment for Regulated Substances and the processes where these substances are used
  • Accidental release prevention program  
  • Equipment, procedures and training to prevent releases and mitigate releases  
  • Comprehensive emergency response plan  

The focus of the CalARP Program is prevention through planning and hazard awareness.  For more information regarding the local implementation of the CalARP Program, please contact the CalARP Supervisor, Maryam Sedghi  by e-mail at or by phone at (858) 505-6893.

California Environmental Reporting System (CERS) and CalARP

At this time there are no CalARP-specific CERS reporting requirements, however, all CUPA-regulated businesses are required by law (Assembly Bill 2286) to submit business information through CERS for the following elements:

  • Unified Program Facility Permit
  • Hazardous Materials Business Plan (HMBP)
  • Hazardous Waste
  • Hazardous Waste Onsite Treatment
  • Hazardous Waste and Materials Tank Closures
  • Remote Waste Consolidation
  • Recyclable Materials Reports
  • Underground Storage Tanks (UST)
  • Aboveground petroleum storage over 1,320 gallons (APSA/SPCC)

CERS has already been pre-populated with your existing facility information and is available to you through the CERS Business Portal.  For directions on how to access your facility information, please refer to our CERS Information website.  

Please do not submit your Risk Management Plan or other CalARP documents through CERS. You may e-mail, fax or mail documents to the CUPA.
