When constructed, this project will transport natural gas liquids from Ohio and the Pittsburgh area to the Marcus Hook facility for both domestic distribution and export The Manner East 2 pipeline is an approximately $2.5 Billion underground pipeline system, consisting of up to two (2) pipelines approximately 350 miles in length. The first, a 20-inch pipeline would have an initial capacity of approximately 275,000 barrels a day with the ability to expand to approximately 450,000 barrels a day to carry natural gas liquids such as propane, ethane and butane east from Ohio and West Virginia into Pennsylvania.

A second pipeline of 16-inches in diameter is being considered as a part of the expansion of the Mariner East 2 system The additional pipeline (if justified) would have an additional capacity of approximately 250,000 barrels a day. Both pipelines would be installed as a part of one construction project.

The steel pipe ,walls of the two pipes being installed are 3/8 inches to 1/2 inches thick.
