Williams Receives FERC Approval to Place Atlantic Sunrise Project into Full Service; Plans to Place Project into Service Oct. 6

Williams today reported that the Federal Energy Regulatory Commission (FERC) has approved the Company’s request to place its Atlantic Sunrise project into full service. The Company plans to place the project into full service on Oct. 6, 2018.

Backed by long-term shipper commitments, the historic project increases the design capacity of the Transco pipeline, the largest-volume natural gas pipeline system in the United States, by 1.7 billion cubic feet per day (approximately 12 percent) to 15.8 billion cubic feet per day. In the process, the project further strengthens and extends the bi-directional flow of the Transco system, directly connecting Marcellus gas supplies with markets as far south as Alabama.

“This project makes the largest-volume pipeline system in the country even larger, further executing on our strategy to connect premier natural gas supply areas with the best markets in the country,” said Alan Armstrong, Williams president and chief executive officer. “The project is significant for Pennsylvania and natural gas-consuming markets all along the East Coast, alleviating infrastructure bottlenecks and providing millions of consumers direct access to one of the most abundant, cost-effective natural gas supply sources in the country.”

Williams Chief Operating Officer Micheal Dunn added, “I’m proud of our project team for their focus and carefully executing this complex project in a safe and environmentally responsible manner. Their efforts have truly distinguished this project, positively collaborating with regulators, key stakeholders and communities to overcome challenges and install this critical infrastructure thoughtfully without experiencing any significant injuries or environmental issues. Even in the final months of construction, as some segments of the project area sustained more than 20 inches of rainfall, our teams acted quickly to restore the right-of-way and ensure environmental compliance requirements were met.”
