2137-AF06 201810 The Regulatory Plan and the Unified Agenda of Federal Regulatory and Deregulatory Actions 2137 Pipeline and Hazardous Materials Safety Administration PHMSA 2100 Department of Transportation DOT Pipeline Safety: Amendments to Parts 192 and 195 to Require Valve Installation and Minimum Rupture Detection Standards

PHMSA is proposing to revise the Pipeline Safety Regulations applicable to newly constructed or entirely replaced natural gas transmission and hazardous liquid pipelines to improve rupture mitigation and shorten pipeline segment isolation times in high consequence and select non-high consequence areas. The proposed rule defines certain pipeline events as "ruptures" and outlines certain performance standards related to rupture identification and pipeline segment isolation. PHMSA also proposes specific valve maintenance and inspection requirements, and 9-1-1 notification requirements to help operators achieve better rupture response and mitigation. These proposals address Congressional mandates, incorporate recommendations from the National Transportation Safety Board, and are necessary to reduce the serious consequences of large-volume, uncontrolled releases of natural gas and hazardous liquids.
