El Paso's Tennessee Gas Pipeline Announces 300 Line Expansion Project

HOUSTON, TX, Aug 05 (MARKET WIRE) --
Tennessee Gas Pipeline Company ("Tennessee"), a wholly owned subsidiary
of El Paso Corporation (NYSE: EP), today announced the results of a
binding open season for its 300 Line Expansion Project. Equitable Energy
LLC, a subsidiary of Equitable Energy (NYSE: EQT), executed a binding
precedent agreement for a 15-year term and was awarded 300,000 Dth/d,
which represents 100 percent of the project's capacity. The project links
Equitable's Appalachian production to northeast markets. The expansion
facilities will consist of approximately 125 miles of 30-inch pipe loop
and approximately 46,000 horsepower of additional compression facilities
to be constructed in Tennessee's existing pipeline corridor in
Pennsylvania and New Jersey. Tennessee has entered into a fixed price
agreement to lock in its pipe costs.

"We're excited to have Equitable, a major gas producer in the Appalachian
basin, become one of the largest shippers on our system," said Bryan
Neskora, Chief Commercial Officer of Tennessee. "This project strengthens
Tennessee's position in the Northeast with diversified supplies and a
significant increase in capacity to serve this region."

"Equitable's participation in this project exemplifies our commitment to
support the expansion of much needed pipeline capacity out of the
Appalachian Basin," said Randall Crawford Senior Vice President of
Equitable Resources. "The project enables Equitable to deliver more of our
produced gas to the highly valued Northeast markets."

Construction of the project is subject to regulatory approval from the
Federal Energy Regulatory Commission ("FERC") and other agencies.
Tennessee plans to file its certificate application with the FERC during
the second quarter of 2009, with phased construction anticipated during
2010 and 2011, pending receipt of the necessary regulatory approvals for
the project.
