Gas Pipeline Safety

Safety is our Top Priority

Safety is the top priority for Mobile Gas and the natural gas industry. In fact, according to U.S. Department of Transportation statistics, the natural gas pipeline transportation system is the safest form of energy transportation. In addition to complying with federal and state regulations, Mobile Gas undertakes a number of initiatives to ensure the safe operation of our natural gas pipeline system, including damage prevention programs, visual pipeline inspections, leak surveys, corrosion prevention, and public awareness and consumer education campaigns.

Markers Indicate Major Pipelines Near you

Pipeline markers indicate major pipelines in the area. Most natural gas pipelines are buried underground. Markers indicate only the general, not exact, location of pipelines. Markers also do not indicate the depth or number of pipelines in an area. To identify operators of major gas pipelines in your area and view maps with the general locations of these pipelines, visit the National Pipeline Mapping System’s website.

In most cases, underground gas lines on your property are not marked. Be sure to always call 8-1-1 before starting any excavation work, even when markers are located within your planned work area. This will provide you with more accurate indications of where pipelines and other utilities are located. Carefully dig around marked pipelines to avoid damaging any pipelines that may be close to the ground surface.


Contractors and Excavators

A major cause of pipeline leaks is third-party damage. This is damage caused by contractors or excavators digging, grading, and performing other types of work along roadways and on public and private property. Damage can occur on any size project so, whether you are building a major development or simply doing a little landscaping, always call 8-1-1 at least two days before starting the work.

No damage is too small to report. A slight gouge, dent, or scraped coating on a pipeline can eventually become a leak. Even if you think the damage to a pipeline or its attached components is minor, you should still notify Mobile Gas immediately by calling 251-476-8052. This will allow Mobile Gas to take steps to prevent pipeline problems in the future.

Excess Flow Valves

Safety is a core value at Mobile Gas. We take this responsibility seriously, so we want to inform you about a recent federal regulation concerning gas pipeline safety. You have the option to request installation of an Excess Flow Valve (EFV) on your existing gas service line. An EFV is a mechanical safety device installed near the gas main on the natural gas service line to your meter. In the event of a service line break, this device would activate to minimize the flow of gas. For example, if an excavator accidentally digs into your gas service line in your yard, the EFV would automatically minimize the flow of gas at the location of the damage.

EFV Information and Conditions

To install an EFV, an excavation is required where the existing natural gas service line connects to the natural gas main. Your gas service would also be interrupted for a short period of time while we install this equipment. Many customers already have an EFV installed on their existing service line. To find out if you have one, look at your gas meter and see if there is a small tag attached to the meter setup that identifies an EFV being on the service. EFVs will not operate on all gas service lines, however. If you are interested, we will need to do an analysis to determine if one is possible for your service. If your service is determined to be eligible and you choose to add the optional equipment, you will be charged a one-time fee to cover the cost of the installation. Our goal is to keep the cost of this installation as low as possible. The minimum cost is expected to be $1200. Costs may increase with restoration efforts, including paving and reseeding grassy areas. To learn more, please give us a call: 251-476-8052
