U.S. Department of TransportationThe National Pipeline Mapping System (NPMS) is a geographic information system (GIS) created by the U.S. Department of Transportation, Pipeline and Hazardous Materials Safety Administration (PHMSA), Office of Pipeline Safety (OPS) in cooperation with other federal and state governmental agencies and the pipeline industry. The NPMS consists of geospatial data, attribute data, public contact information, and metadata pertaining to the interstate and intrastate hazardous liquid trunklines and hazardous liquid low-stress lines as well as gas transmission pipelines, liquefied natural gas (LNG) plants, and hazardous liquid breakout tanks jurisdictional to PHMSA. The Pipeline and Hazardous Materials Safety Administration uses the NPMS as a tool to support various regulatory programs, pipeline inspections, and authorized external customers.See the NPMS website for the most recent version of pipeline data.Filesutil-npmsengPublicNational Pipeline Mapping System [Minnesota]OtherMinnesotaMinnesota Geospatial Commons
