National Pipeline Mapping System

National Pipeline Mapping System

The federal government provides online maps through the National Pipeline Mapping System (NPMS) that show the approximate location of gas and hazardous liquids transmission pipelines in relation to specific addresses, major roads, zip codes, cities and counties. NPMS also provides non-emergency contact information for transmission pipeline operators in your community.

Watch the short video below to learn how to use NPMS to find information about pipelines located near your school. NPMS is available online at www.npms.phmsa.dot.gov.  Click on the “NPMS Public Map Viewer” button to begin your search.
