Start Preamble June 12, 2009.

The staff of the Federal Energy Regulatory Commission (FERC or Commission) has prepared an environmental assessment (EA) on the natural gas pipeline facilities proposed by Southern Natural Gas Company (SNG) for the South System Expansion III Project (SSE III Project) and by Southeast Supply Header, LLC (SESH) for the Joint Pipeline Expansion Phase II Project (JPE Phase II Project) in the above-referenced dockets.

The EA was prepared to satisfy the requirements of the National Environmental Policy Act. The staff concludes that approval of the proposed project, with appropriate mitigating measures, would not constitute a major federal action significantly affecting the quality of the human environment.

The EA assesses the potential environmental effects of the construction and operation of the proposed natural gas pipeline facilities including:

SSE III Project

  • The Thomaston-Griffin Branch Third Loop (Thomaston-Griffin Loop), 31.2 miles of 36-inch-diameter pipeline loop in Upson, Lamar, and Spalding Counties, Georgia;
  • The South Atlanta-Austell Replacement, replacement of 10.9 miles of the existing 18-inch-diameter pipeline with 30-inch-diameter pipeline in Fulton and Clayton Counties, Georgia, and construction of the Plant McDonough Meter Station in Fulton County;
  • The South Main Third Loop Line (Gwinville Loop), 12.0 miles of 36-inch-diameter pipeline loop in Jefferson Davis and Simpson Counties, Mississippi;
  • The South Main Third Loop Line (Enterprise Loop), 7.7 miles of 36-inch-diameter pipeline loop in Lauderdale County, Mississippi, and Choctaw and Sumter Counties, Alabama;
  • An additional 10,310 horsepower (hp) of compression and associated ancillary facilities installed at SNG's existing Bay Springs Compressor Station in Jasper County, Mississippi;
  • The South Main Third Loop Line (Bay Springs Loop), 2.4 miles of 36-inch-diameter pipeline in Clarke County, Mississippi;
  • The South Main Fourth Loop Line (Gallion Loop), 5.2 miles of 36-inch-diameter pipeline loop in Hale and Perry Counties, Alabama;
  • The South Main Replacement (Elmore Replacement), replacement of 11.7 miles of 16-inch-diameter pipeline with 42-inch-diameter pipeline in Elmore County, Alabama; and
  • An additional 7,000 hp of compression and associated ancillary facilities at the existing Ellerslie Compressor Station in Harris County, Georgia.

SNG would construct its proposed facilities in three phases beginning in the first quarter of 2010, and all facilities would be in service by the second quarter of 2012.

JPE Phase II Project

  • An additional 12,891 hp (15,000 hp nominal) of compression and associated ancillary facilities at the existing Delhi Compressor Station near Delhi, Richland Parish, Louisiana; and
  • An additional 12,712 hp (15,000 hp nominal) of compression and associated ancillary facilities at the existing Gwinville Compressor Station near Gwinville, Jefferson Davis County, Mississippi.

SESH would begin construction in October 2009, and proposes an in-service date in July 2010.

The EA has been placed in the public files of the FERC. A limited number of copies of the EA are available for distribution and public inspection at: Federal Energy Regulatory Commission, Public Reference Room, 888 First Street, NE., Room 2A, Washington, DC 20426, (202) 502-8371.
