Pipeline
From Wikimarcellus
Major natural gas pipelines are being expanded throughout the Appalachian region where the Marcellus shale formation is found. Two of the major ones are the Millennium Pipeline in New York State and the Tennesee Pipeline that cuts through Pennsylvania. There are many smaller gathering pipeline systems operated by individual natural gas exploration and production companies.
