The federal government 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.
You can also use NPMS to access contact information for transmission pipeline operators in your community. Operator contact information can be sorted by state, county or zip code and typically includes the operator’s name, product transported, contact name and phone number. The U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA) manages NPMS.
Currently, NPMS does not include gathering or distribution pipelines. Some states regulatory agencies also provide maps showing the general location of pipelines in their state. Call 811 or your local One-Call center to have gathering or distribution lines located and marked before digging.
