California Accidental Release Prevention (Cal ARP) Program 

The California Accidental Release Prevention Program (Cal ARP) requires any business that handles more than threshold quantities of an extremely hazardous substance per California regulations to develop a Risk Management Plan (RMP). The RMP is implemented by the business to prevent or mitigate releases of regulated substances that could have off-site consequences through hazard identification, planning, source reduction, maintenance, training, and engineering controls.


California Code of Regulations:  Title 19, Division 2, Chapter 4 (Area Plan) and 4.5 (Cal ARP)
