Interactive map of pipelines in the United States

Screenshot of the National Pipeline Mapping System Public Viewer

The National Pipeline Mapping System (NPMS) Public Viewer from the Pipeline and Hazardous Materials Safety Administration allows users to view pipelines and related information by individual county for the entire United States. The map includes:

  • Gas and hazardous liquid pipelines
  • Liquefied natural gas (LNG) plants
  • Breakout tanks (tanks used for storage or flow relief)
  • Pipeline accidents and incidents going back to 2002

Users can click on individual pipelines to find operator information and contact details, pipeline status and length, and the commodity being carried by the pipeline. For accidents, available information includes the date of the accident, the name of the operator, the material released, the total volume lost and recovered, and the cause of the accident.

The map does not include gathering or distribution pipelines, so it does not show pipelines that deliver gas to people's homes. The minimum accuracy of the pipeline information on the viewer is +-500 ft. For higher precision in locating pipelines, more information, and contact details for the NPMS, visit the NPMS FAQs.
