Project Overview

The 1,230-mile Appalachia-to-Texas (ATEX Express) pipeline is designed to transport natural gas liquids (NGL) from the Marcellus-Utica Shale region of Pennsylvania, West Virginia and Ohio to the Texas Gulf Coast near Houston. ATEX Express will deliver ethane, which is valuable to petrochemical plants as a feedstock.

Approximately 1,230 miles.

The northern portion of the ATEX pipeline will involve the construction of 369 miles of 20-inch diameter pipeline from Washington County, Pennsylvania to Seymour, Indiana where it will connect with an existing Enterprise pipeline. That pipeline, which currently transports refined products from the Gulf Coast to the Midwest, will be placed into ethane service and the flow direction will be reversed. At its southern terminus ATEX Express will have access to a new 55-mile pipeline to be built by Enterprise Products that will extend from Beaumont, Texas to the company’s NGL storage complex at Mont Belvieu, Texas.

Projected In-Service Date:
Subject to the required regulatory approvals, the pipeline is expected to begin service in the first quarter of 2014.

Enterprise Products Partners, L.P.

The pipeline will have an initial capacity of 125,000 BPD and could be expanded to 260,000 BPD as demand increases. The project is supported by long-term transportation agreements.

Economic Benefits
There will be multiple benefits for states and local communities along the proposed pipeline route in addition to the country as a whole.

  • Jobs – The project is expected to generate as many as 4,000 construction and full-time jobs in addition to employment resulting from increased production activity, as well as new and expanded ethylene plants in the U.S.
  • Revenue – States and counties will benefit from taxes generated by continued operation of the pipeline and related economic activity.
  • Increased Local Commerce – Due to the influx of activity during construction, the project is expected to boost the sale of goods and services in communities along its route.
  • Greater Supply and Energy Independence – Ultimately, the pipeline will benefit the United States by promoting the development and use of domestic energy. Increased fractionation activity will promote greater supply and improved economics for local propane distributors.
  • Landowners – Property owners along the route would be compensated for the use of the portion of their land that is used for pipeline right-of-way.
