The incremental storage space, which will be available upon the completion of expansion facilities, is being developed in concert with National Fuel Gas Supply’s west-to-east and Appalachian Lateral pipeline transportation projects, and involves the expansion of several of National Fuel Gas Supply’s existing underground natural gas storage fields. The incremental capacity will be phased in over a two-year period, with the initial phase projected to go in service on April 1, 2011.

National Fuel Gas Supply also announced that the deadline for the Appalachian Lateral open season launched on August 5, 2008, will be extended until October 3, 2008, to coincide with the storage expansion open season.

The Appalachian Lateral open season offers capacity on a newly proposed pipeline system that will provide new interstate pipeline infrastructure to bring to Northeast markets the new gas supplies to be produced from the Marcellus Shale and other Appalachian producing formations.

The Appalachian Lateral may serve as a complement to National Fuel Gas Supply’s previously announced west-to-east project, which is designed to move Rockies Express gas supply from Ohio to the Northeast.
