Williams receives key Pennsylvania DEP and U.S. Army Corps of Engineers permits for Atlantic Sunrise Project

Williams reported yesterday that the Pennsylvania Department of Environmental Protection (PADEP) and U.S. Army Corps of Engineers have issued required permits for the Atlantic Sunrise pipeline project – an expansion of the existing Transco natural gas pipeline to connect abundant Marcellus gas supplies with markets in the Mid-Atlantic and Southeastern U.S.

The company received the Chapter 105 (Water Obstruction and Encroachment) and Chapter 102 (Erosion and Sediment Control) permits from PADEP on Aug. 30 and the Clean Water Act Section 404 permit from the U.S. Army Corps of Engineers on Aug. 29.

The receipt of these remaining state and federal permits will allow the company to immediately commence the process of requesting a Notice to Proceed with construction from the Federal Energy Regulatory Commission (FERC), targeting commencing greenfield pipeline construction in Pennsylvania this fall. The full project capacity is scheduled to be placed into service in mid-2018.

The FERC authorized the project in February 2017, concluding that environmental impacts associated with the project would be reduced to “less than significant levels” with the implementation of mitigation measures proposed by the company and FERC.
