Pipeline Safety

More than 2.2 million miles of pipelines and mains quietly, reliably and efficiently deliver natural gas everyday for use by residential, commercial and industrial customers.

Almost all of the natural gas consumed in the United States is produced domestically and delivered via a transmission and distribution infrastructure that has an outstanding safety record.

Pipeline Markers

Whether you are at home, at work, or in a public place, it’s likely you are in an area served by natural gas pipelines. Since pipelines are underground, line markers are sometimes used to indicate their approximate location along their route. The markers display the material transported in the line, the name of the pipeline operator, and the telephone number where the operator can be reached in the event of an emergency. Markers only indicate the general location of a pipeline and cannot be relied upon to indicate the exact position. Because many lines are not marked, it is critical that you Call Before You Dig (800.922.4455) prior to any excavation.

Our Commitment to Safety

We work with industry groups to continually enhance natural gas pipeline safety and training methods. At the state level, we work with regulators on programs designed to ensure the safe operation of the natural gas distribution system for customers and residents. And, as new technologies are developed in natural gas pipeline design, construction, inspections, and operations, we will continue to invest in pipeline integrity programs that will allow for the safe and reliable delivery of natural gas.

Excess Flow Valve Notice

An Excess Flow Valves (EFV) is a device designed to shut off the flow of natural gas automatically if the service pipe breaks between the natural gas main in the street and the customer’s gas meter. Customers may request to have an EFV installed on their service if one does not already exist, and if the service allows for the proper installation of this device.
