According to the company, 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. The Ruby Pipeline is expected to have an initial design capacity of up to 1.5 billion cubic feet per day.

Jim Cleary, president of El Paso’s Western Pipelines, said: “Additional capacity out of the Rockies is needed, and Ruby is the right solution to help end users and producers.

“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 Federal Energy Regulatory Commission (FERC) approval.”

El Paso Corporation is a provider of natural gas and related energy products. The company claims to own North America’s largest interstate natural gas pipeline system and one of North America’s largest independent natural gas producers.
