About NPMS Public Viewer

The Pipeline and Hazardous Materials Safety Administration’s (PHMSA) National Pipeline Mapping System (NPMS) has developed the NPMS Public Viewer iPhone app to allow the public to view hazardous liquid and gas transmission pipeline maps. The user can see who operates a pipeline, what it transports, and who to contact for further information. To get started, a user may choose one county or offshore area (including state waters or federal waters) or choose to see pipelines closest to the user’s current location. For more information about the NPMS, or to access the full desktop browser version of the NPMS Public Map Viewer, go to the NPMS website at https://www.npms.phmsa.dot.gov/.
