This page provides information on current activities related to Mountain Valley Pipeline's (MVP's) Southgate Amendment Project. The proposed project includes the construction of approximately 31.3 miles of 30-inch diameter pipeline; with 26.1 of those miles to be located in Pittsylvania County, Virginia. (The remaining 5.2 miles of pipeline would be located in Rockingham County, North Carolina.) The purpose of the pipeline is to transport natural gas from an interconnection point with the MVP Main Line project in Virginia to an interconnection point with the East Tennessee Natural Gas, LLC, system in North Carolina.   

In Virginia, the construction of natural gas pipelines is regulated under several environmental programs.
