Mountaineer XPress pipeline project will transport gas from the Marcellus and Utica shale plays in the Appalachian Basin. The pipeline will start near the Ohio River in Marshall County and head south to Wayne County, through West Virginia counties bordering eastern Ohio. The project includes three new compressor stations and modifications to three existing compressor stations.
