Find Pipelines Near Your School to help you quickly respond to a pipeline problem and protect students, staff and facilities.
Permanent Pipeline Markers
Pipeline
 operators place permanent signs, called pipeline markers, along 
transmission, gathering and hazardous liquids pipeline routes, at 
roadway and railway crossings and at aboveground facilities to identify 
the general location of a pipeline. Lines maintained by your local gas company typically do not have permanent pipeline markers.
Markers can vary in size, shape and color, but all markers include 
important information about the pipeline, including the product 
transported, the pipeline operator’s name and the operator’s emergency 
contact number.  Line markers do not indicate depth of the line, the 
number of lines in the area or the exact location of a pipeline.
If you are planning an excavation or building project on your school 
property, even if you have identified a pipeline marker, you must call 
811 or your local One-Call center to have pipelines located and marked 
before digging.  Depending on the specifics of your school’s project, 
the pipeline operator may elect to be on-site during excavation.
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, please contact the pipeline operator. 
School Pipeline Safety Map (available for participating schools)
If
 your school participates in the School Pipeline Safety Partnership 
program, you can access an online aerial map of your school showing the 
general location of nearby pipelines by accessing your school’s pipeline safety information page.
In addition to a map, school pipeline safety pages include the pipeline 
operator’s emergency contact number, information about the pipeline and 
what it transports, and non-emergency contact information for local 
pipeline and school personnel.
 
National Pipeline Mapping System Maps (available for all schools)
The federal government provides online maps to help you locate pipelines in 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 also 
provides non-emergency contact information for transmission pipeline 
operators in your community.

Aboveground Facilities
In addition to underground pipelines, your school may be located near 
aboveground components of the pipeline system, including compressor and 
pumping stations, metering stations and storage facilities.  Pipeline 
markers are posted to identify aboveground facilities as well.
Metering stations and compressor and pumping stations are located along 
gathering and transmission lines.  Metering stations measure flow of 
product in and out of the pipeline system, and compression and pumping 
stations push products through the pipeline.  Storage facilities store 
natural gas or other products.  If you have questions about an 
aboveground facility near your school, contact the operator listed on 
the pipeline marker for more information.
