PHMSA Pipeline Repair Criteria Modernization (Gas Transmission & Hazardous Liquid)

Current understanding

PHMSA has issued a proposed rule to modernize anomaly response and repair criteria for gas transmission and hazardous liquid pipelines, incorporating engineering concepts developed over the past two decades. The practical effect would be to update timelines, thresholds, and methods operators use when responding to detected pipeline defects. Status: proposed rule.
