Transcontinental Gas Pipe Line Company, LLC; Notice of Availability of Draft General Conformity Analysis for the Atlantic Sunrise Project

In accordance with the National Environmental Policy Act of 1969, the Clean Air Act, and the Federal Energy Regulatory Commission's (Commission or FERC) regulations, Commission staff has prepared this draft General Conformity Determination (GCD) for the Atlantic Sunrise Project (Project) to assess the potential air quality impacts associated with the construction of natural gas transmission facilities proposed by Transcontinental Gas Pipeline Company, LLC (Transco).

The FERC staff concludes that the Project would achieve conformity in Pennsylvania through the transfer of Emission Reduction Credits. FERC staff will issue a final GCD to address any changes necessary and respond to comments.

The Project would involve the construction and operation of about 199.4 miles of pipeline facilities and appurtenant aboveground facilities, including:

• 185.9 miles of new natural gas pipeline in Columbia, Lancaster, Lebanon, Luzerne, Northumberland, Schuylkill, Susquehanna, and Wyoming Counties, Pennsylvania (58.7 miles of 30-inch-diameter and 127.3 miles of 42-inch-diameter pipeline);
• 11.0 miles of new pipeline looping in Clinton and Lycoming Counties, Pennsylvania (2.5 miles of 36-inch-diameter and 8.5 miles of 42-inch-diameter pipeline);
• 2.5 miles of 30-inch-diameter pipeline replacements in Prince William County, Virginia;
• two new compressor stations in Columbia and Wyoming Counties, Pennsylvania (Compressor Stations 610 and 605);
• additional compression and related modifications to two existing compressor stations in Columbia and Lycoming Counties, Pennsylvania (Compressor Stations 517 and 520) and one in Howard County, Maryland (Compressor Station 190);
• other modifications would be taking place at Compressor Stations 145, 150, 155, 160, 170, 185, and 190 across Maryland, North Carolina, and Virginia;
• two new meter stations and three new regulator stations would be constructed and operated in Pennsylvania. There would also be modifications at an existing meter station, and the construction and operation of additional ancillary facilities would occur in Pennsylvania; and
