TULSA, Okla. -- (Business Wire)

Williams Partners L.P. (NYSE:WPZ) continues to gauge interest for the remaining capacity on Atlantic Access, a proposed expansion of its Transco interstate pipeline. As a result of discussions with potential shippers and other market inquiries, Transco is proposing certain modifications to the project, including increasing the total firm transportation capacity, offering additional firm transportation paths, and revising the proposed in-service date to December 2015.

The revised open season will run from April 16 to July 13, 2012, to obtain shipper commitments for the Atlantic Access project, which connects natural gas supplies originating in western West Virginia and Pennsylvania to growing markets in the Northeast, Mid-Atlantic, Southeast and Gulf Coast regions.

Williams (NYSE: WMB) owns approximately 69 percent of Williams Partners, including the general-partner interest.

The revised proposal is a result of feedback from producers and more closely aligns future infrastructure with the timing and geographical needs of the market. The proposed Atlantic Access project now increases capacity for the pipeline from 1.8 million dekatherms per day (MMdt/d) to 2.3 MMdt/d in order to transport growing supplies of natural gas from northern Pennsylvania bi-directionally along Transco’s existing Leidy Line to Leidy and other premium markets along the Atlantic seaboard.

Transco is now proposing a total of six firm transportation paths under the project. Two of the three original paths have been fully subscribed. The modified proposal provides a westward path to Leidy and two new paths eastward from the supply area to growing natural gas markets in both the northeast and the southeast U.S. For further details about the transportation paths, please view the Supplemental Open Season.

The capacity, scope and cost of the Atlantic Access project will be shaped by the results of the open season. The proposed project will be subject to approval by the Federal Energy Regulatory commission and other agencies.
