Industry statistics show that the most common cause of pipeline damage is excavation activity.  Protect your employees, equipment and reputation by knowing where pipelines are located and how to respond to or prevent a pipeline leak or rupture.

Always contact your local One-Call center, or call 811, to have pipelines and other underground utility lines marked prior to starting an excavation project.  Once lines have been located, respect the marks and use appropriate equipment and excavation procedures near the pipeline.

More than two million miles of pipelines crisscross the United States safely transporting energy products every day.  Pipeline operators monitor their lines 24 hours a day, seven days a week and regularly inspect lines to ensure safe operations.  If you have questions about how to properly dig near a pipeline or how to interpret the marks, contact the pipeline operator.
