CalARP

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 chlorine gas, ammonia gas, and other toxic gases.  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 call the CalARP Specialist at (619) 338-2453.
