Williams, one of the premier natural gas companies in the United States, announced that it is seeking authorization from the Federal Energy Regulatory Commission (FERC) to expand the 60 percent Williams-owned Transco, the nation's largest volume and fastest growing interstate natural gas pipeline system running over 10,000 miles in length.

The project, dubbed Atlantic Sunrise, will transport 1.7 billion cubic feet of natural gas per day to markets in the Mid-Atlantic and Southeastern United States.

“Atlantic Sunrise is a vital piece of North American energy infrastructure needed to transport low-cost, abundant supplies of natural gas from the Marcellus producing region in Pennsylvania to hungry markets along the Atlantic Seaboard,” said Rory Miller, senior vice president of Williams Partners’ Atlantic-Gulf operating area.
