Description:  TITLE: Pipeline Safety: Requirement of Valve Installation and Minimum Rupture 
Detection Standards  
AGENCY: Pipeline and Hazardous Materials Safety Administration (PHMSA), DOT  
ACTION: Final rule  
SUMMARY: PHMSA is revising the Federal Pipeline Safety Regulations applicable to most newly 
constructed and entirely replaced onshore gas transmission, Type A gas gather ing, 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 equivalen t technologies, and establishes minimum performance standards 
for those valves' operation to prevent or mitigate the public safety and environmental consequences

  of pipeline ruptures. This final rule establishes requirements for rupture -mitigation valve sp acing, 
maintenance and inspection, and risk analysis. The final rule also requires operators of gas and 
hazardous liquid pipelines to contact 9 -1-1 emergency call centers immediately upon notification of 
a potential rupture and conduct post -rupture investi gations and reviews. Operators must also 
incorporate lessons learned from such investigations and reviews into operators' personnel training 
and qualifications programs, and in design, construction, testing, maintenance, operations, and 
emergency procedure  manuals and specifications. PHMSA is promulgating these regulations in 
response to congressional directives following major pipeline incidents where there were significant 
environmental consequences or losses of human life. The revisions are intended to a chieve better 
rupture identification, response, and mitigation of safety, greenhouse gas, and environmental justice 
impacts.  
The effective date of this final rule is 5 October 2022.
