On Friday, the DOT’s Pipeline and Hazardous Material Safety Administration published a final rule in the Federal Register (87 FR 20940-20992) for “Pipeline Safety: Requirement of Valve Installation and Minimum Rupture Detection Standards”. The notice of proposed rulemaking for this rule was published in February 2020.
According to the Summary of this final rule in the preamble this rule will:
• Revise 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,
• Require operators of these lines
to install rupture-mitigation 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,
• Establish requirements for
rupture-mitigation valve spacing, maintenance and inspection, and risk analysis,
• Require 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
investigations and reviews, and
• Require operators to 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.
The preamble to the rule provides a section-by-section analysis of the changes made to 49 CFR Part 192 for gas pipelines and Part 195 for hazardous liquid pipelines.
The effective date for this rule is October 5th,
2022.
