Williams Completes Pipeline Expansion to Provide Additional Natural Gas Service to Northeast

TULSA, Okla., Nov. 19  /PRNewswire-FirstCall/ -- Williams (NYSE:WMB) today announced it has placed an expansion of its Transco natural gas pipeline system into service, increasing firm transportation capacity into the northeastern United States by 102,000 dekatherms per day.

The Sentinel expansion project was completed in two phases, the second of which was placed into service this week and increased capacity by 102,000 dekatherms per day. The first phase of the project, which was placed into service in December 2008, increased capacity by 40,000 dekatherms per day.

"This expansion allows us to continue meeting the region's growing energy needs by providing clean-burning natural gas in time for the winter heating season," said Phil Wright, president of Williams' natural gas pipeline business. "This was a challenging project in a densely-populated part of the country. We sincerely appreciate the cooperation and patience of the many landowners who worked closely with us during pipeline construction."

Phase II construction included the addition or replacement of 14 miles of pipe and eight meter station modifications at various locations in Pennsylvania and New Jersey. Phase I construction included the addition of approximately four miles of pipe in Pennsylvania, two meter station modifications and compressor station upgrades.

The Transco pipeline is a 10,500-mile pipeline system which transports natural gas to markets throughout the northeastern and southeastern United States. This expansion increases the total system capacity of the Transco pipeline to approximately 8.6 billion cubic feet per day.
