Natural gas and hazardous liquid pipelines will have to install automatic shutoff valves (ASVs), remote control valves (RCVs) or equivalent technology on all newly constructed or entirely replaced pipelines that have nominal diameters of 6 inches (152.4 mm) or greater if the Pipeline and Hazardous Materials Safety Administration (PHMSA) finalizes a proposal it issued in February.
