In a recently released draft report, the U.S. Chemical Safety Board (CSB) proposes recommendations for substantial changes to the way refineries are regulated in California. Entitled “Regulatory Report: Chevron Richmond Refinery Pipe Rupture and Fire,” the CSB draft calls on California to replace the current patchwork of largely reactive and activity-based regulations with a more rigorous, performance-based regulatory regime – similar to those successfully adopted overseas in regions such as the United Kingdom, Norway, and Australia – known as the “safety case” system.
