FINAL RULE: Valve Installation and Minimum Rupture Detection Standards

PHMSA issued a Final Rule on March 31, 2022 revising the Federal Pipeline Safety Regulations applicable to most newly constructed and entirely replaced onshore gas transmission, Type A gas gathering, and
hazardous liquid pipelines with diameters of 6 inches or greater. In the revised regulations,
PHMSA requires operators of these lines to install rupture-mitigation valves (i.e., remote-control
or automatic shut-off valves) or alternative equivalent technologies, and establishes minimum
performance standards for those valves’ operation to prevent or mitigate the public safety and
environmental consequences of pipeline ruptures. The effective date of this final rule is October 5, 2022.
