Yesterday, the OMB’s Office of Information and Regulatory Affairs (OIRA) announced that it had received a notice of proposed rulemaking (NPRM) from the DOT’s Pipeline and Hazardous Materials Safety Administration on “Pipeline Safety: Repair Criteria for Hazardous Liquid and Gas Transmission Pipelines”. The advanced notice of proposed rulemaking for this action was published on May 21st, 2025.
According to the Spring 2025 Unified Agenda entry for this rulemaking:
“PHMSA plans a notice of proposed rulemaking that would modify the thresholds at which operators would be required to repair hazardous liquid pipelines, commonly referred to as anomaly repair criteria,” on pipelines located in high-consequence areas (HCA) and could-affect HCAs,” and develop new repair criteria for hazardous liquid pipelines in non-HCAs. PHMSA is also examining changes to the repair criteria for gas transmission pipelines, including the anomaly thresholds for cracks, dents, and certain seam types.”
