The 50-mile, 12-inch pipeline connects growing supplies of ethane from the Marcellus and Utica producing regions with interconnections at the Houston, Pa. ethane hub. Existing third-party pipelines at the hub transport natural gas liquids north to the Sarnia, Ontario petrochemical markets. Planned third-party pipeline projects at the hub will transport NGLs east to various domestic and waterborne markets.


Williams owns 100 percent of the Ohio Valley Ethane Pipeline and is the operator of record.
