On July 8, 2026, PHMSA published a Notice of Proposed Rulemaking (NPRM) that would modernize the federal repair criteria for hazardous liquid and gas transmission pipelines. If adopted, these would be the first significant updates to the repair requirements in nearly 20 years.
The proposal is intended to better align the regulations with current engineering practices, inspection technologies, and repair methods while reducing unnecessary operational disruptions. PHMSA estimates the proposed changes could save pipeline operators approximately $390 million over time by allowing greater flexibility in evaluating and repairing certain pipeline conditions without compromising safety.
Among the proposed changes are updates to repair criteria for dents, gouges, cracks, corrosion, and other anomalies identified during integrity assessments. The rule would also revise repair schedules, clarify existing requirements, and incorporate modern engineering assessment methods that have become common throughout the industry.
This proposed rule follows PHMSA’s 2025 Advance Notice of Proposed Rulemaking, which sought public feedback on opportunities to improve the effectiveness and efficiency of the current repair regulations.
Pipeline operators, engineers, and integrity management professionals should review the proposal carefully to understand how the revisions may affect inspection programs, repair decision-making, and compliance strategies. Comments on the proposed rule are due by September 8, 2026.
