NPMS Public Viewer 1.2

The NPMS Public Viewer iPhone app, developed by US DOT PHMSA, allows the user 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. A user may choose one county’s pipelines or the pipelines closest to the user’s current location. For more information about the NPMS, go to www.npms.phmsa.dot.gov.
