EP EL Paso Corp. (Holding Co.)

El Paso Corporation (NYSE: EP) announced today that it has filed with the Federal Energy Regulatory Commission (FERC) an application, under Section 7(c) of the Natural Gas Act, for a certificate of public convenience and necessity to construct and operate the Ruby Pipeline.

"Additional capacity out of the Rockies is urgently needed, and Ruby is the right solution to help end users and producers," said Jim Cleary, president of El Paso's Western Pipelines. "We have completed the environmental, archaeological, and subsurface assessments for our proposed route and are on track to be in service in March 2011, pending FERC approval."

The proposed 675-mile, 42-inch interstate natural gas pipeline will access growing sources of supply from multiple Rockies' basins and make those supplies available to Nevada, California, and Pacific Northwest markets. Ruby is expected to have an initial design capacity of up to 1.5 billion cubic feet per day.

El Paso Corporation provides natural gas and related energy products in a safe, efficient, and dependable manner. The company owns North America's largest interstate natural gas pipeline system and one of North America's largest independent natural gas producers. For more information, visit www.elpaso.com.
