Be Aware: Pipelines in Your Community

About Arkansas Oklahoma Gas Corp.

Natural Gas is an important source of energy for America’s homes and businesses. Arkansas Oklahoma Gas Corporation (AOG) is privileged to provide energy to our customers in Arkansas and Oklahoma by transporting natural gas through a network of underground pipelines. Year after year, pipelines prove to be one of the safest and most reliable modes of energy transportation. AOG is dedicated to the continued safe operation of our pipelines for your protection and the protection of the environment. We are committed to an outstanding safety record. We maintain 24-hour surveillance and perform routine inspections, computer monitoring, corrosion protection, maintenance/testing programs, and employee training.

Maintaining safety and integrity of pipelines

AOG works hard to maintain the integrity and safety of our pipeline systems. We stay in touch with industry and government organizations to monitor potential threats and study new technologies that will help keep our facilities as safe and secure as possible. AOG will operate, and maintain the facilities in accordance with applicable Federal pipeline Safety standards established by the Department of Transportation. These regulations are intended to protect the public and the environment and to ensure pipeline integrity and safety. Some segments along transmission pipelines have been designated as High Consequence Areas (HCA's) and supplemental hazard and assessment and prevention programs (called Integrity Management Programs) have been developed.

High Consequence Areas

AOG operates natural gas pipelines ranging from ¾-inch to 12-inch in diameter and at pressures from ounces to several hundred PSIG. An odorant is added to all AOG pipelines and facilities. AOG serves Crawford, Sebastian, Franklin, Yell, and Scott counties in Arkansas and Sequoyah, Latimer, Haskell, Le Flore, and Delaware counties in Oklahoma.

How can you tell where a pipeline is located?

The U.S. Department of Transportation requires the use of signs to indicate the location of underground pipelines. Markers like these are located at road, railroad, and navigable waterway crossings. Markers are also posted along the pipeline right-of-way.

The markers will say "Warning Gas Pipeline" and will have AOG’s Name and Phone Number where we can be reached in the event of an emergency.

Are pipeline markers always placed on top of the pipeline?

Markers only indicate the approximate location of the underground pipeline. They are normally not placed directly on top of the pipeline.

  • Signs located near roads, railroads, waterways & along fence lines & pipeline right-of-ways

  • Plastic Posts

  • Pipeline casing vent

It’s a federal crime to remove or deface a pipeline marker sign. Safety is Everyone's Responsibility. Pipeline marker signs are important to public safety.


811 is a new federally-mandated number designated by the FCC to consolidate all local "Call Before You Dig" numbers and help save lives by minimizing damages to underground utilities. One easy phone call to 811 starts the process to get your underground piplines and utility lines marked for FREE. When you call 811 from anywhere in the country, your call will be routed to your state One-Call Center. Once your underground lines have been marked for your project, you will know the approximate location of your pipelines and utility lines, and can dig safely. More information regarding 811 can be found at

Landowners & Right-of-Way

Because pipelines must cross the countryside to deliver products over long distances, the pipeline has many neighbors. The pipeline crosses under creeks and rivers, highways and roads, farmers’ fields, parks, and may be close to homes, businesses or other community centers.

Written agreements, or easements, between landowners and pipeline companies allow pipeline companies to construct and maintain pipeline rights-of-way across privately owned property. Most pipelines are buried below ground in a right-of-way. The working space needed during initial construction may be temporarily wider but the permanent right-of-way width varies depending on the easement, the pipeline system, the presence of other nearby utilities and the land use along the right-of-way. Many of the rights-of-way are 50 feet wide, but may be wider or narrower in specific locations.

These rights-of-way are kept clear to allow the pipeline to be safely operated, aerially surveyed and properly maintained. Pipeline companies are responsible for maintaining their rights-of-way to protect the public and environment, the line itself, and other customers from loss of service. This includes keeping rights-of-way clear from encroachments of any kind including buildings or structures built on top of AOG facilities.

While permanent pipeline markers are located at roads, railways and other intervals along the rights-of-way, these show only the approximate location of the buried pipelines. The depth and location of the pipelines vary within the rights-of-way.

Signs of a Natural Gas Pipeline Leak:

Despite AOG’s best efforts and government oversight, leaks from pipelines do sometimes happen. The best way for you to detect a leak in your neighborhood is to use your senses of sight, smell, and sound. You may have a leak if:

  • you see dead or discolored vegetation that is otherwise green along a pipeline ROW, or see dirt or water blowing near the pipeline ROW;
  • you smell an unusual or pungent, sulfur-like odor along a pipeline ROW;
  • you hear an unusual hissing or roaring sound along a pipeline ROW.

What to do:

  • Leave the area immediately;
  • Call AOG toll-free at (800) 842-5690 or (479) 784-2052 & give the location;
  • Warn others to stay away;
  • Keep ignition sources away from the area and avoid creating a spark;

Public Awareness Survey

We are currently conducting a public awareness survey. Your response will allow us to measure the overall understanding of pipeline safety in America, and assist in the continuous improvement of our communications.
