(Dominion) (NYSE: D); Duke Energy Corporation (NYSE: DUK); Piedmont Natural Gas Co., Inc. (NYSE: PNY); and AGL Resources, Inc. (NYSE: GAS). The company was created to develop, own, and operate the proposed Atlantic Coast Pipeline (ACP or Project), an approximately 603.8-mile-long interstate natural gas transmission pipeline system designed to meet growing energy needs in Virginia and North Carolina (see Appendix A, figure 1). The ACP will be capable of delivering up to 1.5 million dekatherms per day (MMDth/d) of natural gas that will be used to generate electricity, heat homes, and run local businesses. The Project will facilitate cleaner air, increase the reliability and security of natural gas supplies, and provide a significant economic boost in West Virginia, Virginia, and North Carolina. More information is provided at the company’s website at www.dom.com/acpipeline. Atlantic has contracted with Dominion Transmission, Inc. (DTI), a subsidiary of Dominion, to permit, build, and operate the ACP on behalf of Atlantic. Atlantic is seeking authorization from the Federal Energy Regulatory Commission (FERC or Commission) under Section 7(c) of the Natural Gas Act to construct, own, operate, and maintain the following proposed facilities for the ACP system: Mainline Pipeline Facilities: AP-1: approximately 333.1 miles of underground 42-inch outside diameter natural gas transmission pipeline in Harrison, Lewis, Upshur, Randolph, and Pocahontas Counties, West Virginia; Highland, Bath, Augusta, Nelson, Buckingham, Cumberland, Prince Edward, Nottoway, Dinwiddie, Brunswick, and Greensville Counties, Virginia; and Northampton County, North Carolina. AP-2: approximately 186.0 miles of underground 36-inch outside diameter natural gas transmission pipeline in Northampton, Halifax, Nash, Wilson, Johnston, Sampson, Cumberland, and Robeson Counties, North Carolina. Lateral Pipeline Facilities: AP-3: approximately 83.2 miles of underground 20-inch outside diameter natural gas lateral pipeline in Northampton County, North Carolina; and Greensville and Southampton Counties and the Cities
