Use the resources below to learn more about how to safely farm and ranch near pipelines and underground utility lines.
Permanent signs are often placed along the route of underground pipelines and utilities to remind you that lines are located nearby.
Marker signs include the name of the operator, type of line and emergency contact number. Line markers identify the general, but not exact, location of underground lines.
Utility service lines maintained by your local gas company may not have permanent pipeline markers.
Pipeline markers are important safety signs. It is a federal crime to willfully deface, damage, remove or destroy a pipeline marker. If you notice a damaged marker, or accidentally damage a marker, please contact the pipeline or utility line operator.
Pipeline and utility line operators use flags, paint and stakes to mark the location of their lines. Underground pipelines are marked with yellow flags and paint, and electric lines are marked with red flags and paint.
The National Pipeline Mapping System’s (NPMS) Public Viewer allows you to view and print maps of hazardous liquid & gas transmission pipelines.
Maps generated by NPMS show the approximate location of transmission pipelines in relation to specific addresses, major roads, zip codes, cities and counties. Maps do not allow you to identify the exact location of pipelines and should not be used as a substitute for calling 811 prior to agricultural excavation or digging activities.
Watch a tutorial video for how to use NPMS.
You can also use NPMS to access contact information for transmission pipeline operators in your community. 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 state regulatory agencies also provide maps showing the general location of pipelines in their state.
When you call 811, the three-digit number to request an underground line locate, pipeline operators and local utilities will come mark the location of lines they operate free of charge.
Visit www.call811.com to learn more about the services provided by 811 centers near you and the information you’ll be asked to provide when you call.
When planning large projects or land contour activities, including installing ponds, lakes or drainage ditches, call 811 to inquire about a planning ticket that will initiate a consultation meeting with underground pipeline and utility line operators during the planning phase of your project. Planning tickets may not be available in all locations.
Watch the 811 video to learn more about how the 811 service works.
