Pipeline
From Wikimarcellus
Major natural gas pipelines are being expanded throughout the Appalachian region where the Marcellus shale formation is found. Two of the larger ones are the Millennium Pipeline in New York State and the Tennessee Pipeline that cuts through Pennsylvania. There are many smaller gathering pipeline systems operated by individual natural gas exploration and production companies.
In general, the unavailability of pipeline capacity has been a restraining influence upon Marcellus shale development. So far drilling has concentrated on southwestern and northeastern Pennsylvania where interstate pipelines already traverse.
Due to the regulatory hurdles involved in building new pipeline, those companies with some already existing pipeline capacity are at a distinct competitive advantage. For example, EQT Corporation and NiSource are two companies that already have pipelines in Pennsylvania and West Virginia. EQT's makes five interstate pipeline connections. In order to take advantage of this existing capacity, according to a July, 2009 report, EQT was in the process of rerouting its western flowing pipelines in order to transport Marcellus shale gas in the opposite direction towards east coast markets.
