The U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) provides online maps to help you locate pipelines in or near your community through the National Pipeline Mapping System (NPMS).
Maps generated by NPMS show the approximate location of gas and hazardous liquids transmission pipelines in relation to specific addresses, major roads, zip codes, cities and counties. NPMS does NOT include gathering or distribution pipelines. Some states regulatory agencies also provide maps showing the general location of pipelines in their state.
You can use NPMS to obtain contact information for transmission pipeline operators. Operator contact information typically includes the operator’s name, product transported, contact name and phone number. A summary of active mileage by county in xlsx format is also available from their General Public Page. The Association incorporated this data into an Access Database which can be used to generate reports by county. Click here to download the MS Access database file. If you don't have MS Access, you can request a PDF copy of the report for a specific county by sending an email to: firstname.lastname@example.org and include both the state and the county in the email.
