Where Will the E3 Pipeline Run
and How Will it Work?

Where will the pipe run?

The pipeline will be located primarily on road right-of-ways or existing rail or utility easements. This means that the vast majority of the pipeline will run in areas where other utilities such as electric, telephone, cable, sewer, and water already exist. In some areas a new easement will be required to construct the pipeline.

An easement is a purchased right to install the pipeline underground on private property. The landowner will continue to own and use the property. In the event an easement is needed, a representative from ESNG will work directly with the impacted party.

How will the pipe be laid?

The pipe is usually laid after trenching and will sit approximately 3-4 feet below the surface (measured from the top of the pipe) both on and off-shore. To avoid certain geological obstructions and to avoid any negative environmental impact, the pipe may be laid deeper than 3-4 feet below the surface in certain areas.

Wherever an off-shore trench is made to lay the pipe, the substrate will be replaced and allowed to naturally silt in over-top of the pipe. During construction off-shore, the water quality and turbidity will be monitored to ensure no lasting impact will be created on any of our natural resources. Once the pipe has been laid and the dirt or sediment has been replaced over the pipe, normal conditions will be allowed to restore. On land, it is fine to maintain lawns or open fields in the replaced topsoil above the pipe, but trees and shrubs would not be allowed.

How long will the construction take and how might my property be affected?

Unfortunately, any type of construction may create an inconvenience for a period of time. Please be assured that ESNG is aware of this and will use the most non-intrusive and rapid forms of construction available. Following construction, all areas will be promptly restored to a condition equal to their pre-construction state. This includes replacing grass, landscaping, driveways, fences and other structural, vegetative, or aesthetic features. In easement areas, however, we will not replace trees. Rather, we will maintain a clear right-of-way for future surveys and maintenance.

ESNG is committed to providing a safe and environmentally sound project to each landowner whose property is affected during construction and/or right-of-way restoration.

How big is the pipe?

The inside diameter of the pipe will vary between 24, 16, 10 and 6 inches. The pipe is manufactured of high quality carbon steel. Each weld is radiographically inspected (x-rayed) and the new pipe is pressure tested after installation to a minimum of 150% of the final operating pressure authorized.

What happens if there is a problem with one of the pipes?

If there is an unusual operating condition or other problem on the pipeline, company personnel can remotely or manually close valve locations throughout the length of the pipeline. We operate and man a 24-hour / 7-days a week / 365-days a year Gas Control Operations Center where we continuously monitor the pipeline and can quickly respond to any situations.
