The Rover Pipeline is a 713-mile pipeline which transports up to 3.25 billion cubic feet per day of domestically produced natural gas from the rapidly expanding Marcellus and Utica Shale production areas to markets across the U.S. as well as into the Union Gas Dawn Storage Hub in Ontario, Canada, for redistribution back into the U.S. or into the Canadian market.

Directional Drill

Horizontal Directional Drilling (HDD) is a steerable, trenchless method of installing underground pipe in an arc along a prescribed bore path. The use of this method greatly minimizes surface disturbance and reduces environmental impact during construction. This construction method is used to install pipeline underneath waterways, wetlands, culturally sensitive areas, congested neighborhoods and roads.

Installation of a pipeline by HDD is generally accomplished in three stages. The first consists of directional drilling a small-diameter pilot hole along a designated directional path. The second involves enlarging this pilot hole to a diameter suitable for the installation of the pipeline. While the pilot hole is being drilled and enlarged to the appropriate diameter, skilled and trained pipeliners string, or lay out, the pipe to weld the pipe sections together. Once the hole is drilled to the appropriate size, the welded pipeline is installed by connecting to a swivel and pulling the pipe back through the enlarged hole.

Receipt and
Delivery Points


Rover pipeline gathers gas from processing plants in West Virginia, Eastern Ohio and Western Pennsylvania as well as various dry gas-gathering systems for delivery to the Midwest Hub near Defiance, Ohio, where about 68 percent of the gas is delivered via interconnects with existing pipelines in Ohio and West Virginia for distribution to markets across the U.S.

The remaining 32 percent of the natural gas is delivered to markets in Michigan through an interconnect in Livingston County, Michigan, with the existing Vector Pipeline.

Transmission pipelines, like Rover, are highly regulated by federal, state and local regulatory agencies.


Rover incorporated protection of sensitive resources from route, to the design, to the build and the operation of the pipeline. During the initial conception of the pipeline and its route, we selected a path that avoided and minimized the crossing of sensitive environmental resources as our base routing guideline. This, coupled with avoidance of residences, defined the route initially and then the route was field verified by civil surveys and environmental studies that further identified sensitive areas for the project to avoid.

During the construction and planning, Rover took extreme caution when crossing sensitive environmental, wetland or resource areas. In these areas, Rover isolated the construction work area with silt fence and other erosion or sedimentation control techniques to avoid allowing sedimentation to enter into the sensitive area. Rover was able to reduce the workspace to the absolute minimum necessary and minimize disturbances to the root systems by only removing the vegetation roots in the trench and passing lanes, both of which are key precautionary measures.


Pipelines provide the most environmentally safe and most efficient means to transport the energy products that are critical to our way of life and to our economy.

At Energy Transfer and with the Rover Pipeline, safety is our top priority. Our goal is to provide safe and reliable natural gas service to the communities we cross and to the customers we serve. Rover Pipeline implements all federal standards into the design and operations of the pipeline, and in many instances, we exceed federal standards to ensure a safe and reliable pipeline.
