Title: Pipeline Safety: Repair Criteria for Hazardous Liquid and Gas Transmission Pipelines 
Abstract:

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.
