Draft Environmental Impact Statement for the Proposed Southeast Supply Header Project (Docket Nos. CP07-44-000 & CP07-45-000)
Issued: April 27, 2007

The FERC staff has prepared a draft environmental impact statement (EIS) for the Southeast Supply Header, LLP's (SESH) proposed Southeast Supply Header Project (Project).

In order to provide needed new transportation capacity that significantly enhances access to reliable, onshore gas supplies to serve growing demand in the Southeast including Florida, SESH proposes to construct and operate approximately 270 miles of natural gas pipeline and associated ancillary facilities capable of transporting up to approximately 1.14 billion cubic feet per day of natural gas. Specifically, SESH proposes to construct and operate:

    • Approximately 104 miles of 42-inch-diameter natural gas pipeline extending southeasterly from Richland Parish, Louisiana to Lawrence County, Mississippi;

    • Approximately 165 miles of 36-inch-diameter natural gas pipeline extending southeasterly from Lawrence County to Mobile County, Mississippi;

    • Approximately 1.7 miles of 6-, 16-, 20-, 24- and 42-inch laterals in Jefferson Davis, Covington, and Forrest Counties, Mississippi and Mobile, Alabama;

    • Three new natural gas mainline compressor stations: the Delhi, Gwinville, and the Lucedale Compressor Stations, located in Richland Parish, Louisiana, and Jefferson Davis and George County, Mississippi, respectively;

    • two natural gas booster compressor stations, the Collins Booster Station and Petal Booster Station in Covington and Forrest County, Mississippi, respectively; and

    • Other ancillary facilities including thirteen meter and regulator (M&R) facilities, eighteen mainline valves, two tap valves, and three pig launcher and/or receiver facilities.

    This draft EIS was prepared to satisfy the requirements of the National Environmental Policy Act (NEPA) and was prepared in cooperation with the United States Army Corps of Engineers, Fish and Wildlife Service, National Park Service, and the Environmental Protection Agency.

    The FERC staff concludes that if the proposed Project is found to be in the public interest and is constructed and operated in accordance with SESH's proposed minimization and mitigation measures as well as its recommended mitigation measures, the proposed facilities would have limited adverse environmental impacts. The FERC staff reached this conclusion based in part on:

      • SESH would implement its Plan and Procedures which would minimize and mitigate impacts to natural resources during construction and operation of the Project;

      • SESH's proposed route incorporates 70 route modifications developed during the Pre-Filing and NEPA process in response to issues and concerns identified by landowners and reviewing government agencies;

      • SESH would implement an environmental inspection and monitoring program that would ensure compliance with all proposed and recommended mitigation measures;
      • Thirty-one HDDs would be utilized to minimize impacts on special-status waterbodies;

      • Consultation with the FWS as required by Section 7 of the Endangered Species Act would be completed and any appropriate mitigation implemented prior to approval to begin construction;

      • Consultation with the State Historic Preservation Officers and Advisory Council on Historic Preservation as required by Section 106 of the National Historic Preservation Act would be completed before construction would be allowed to begin; and

      • Consistency determinations by the states of Mississippi and Alabama in accordance with the Coastal Zone Management Act would also be required prior to construction.

      The FERC Commissioners will take into consideration staff's recommendations and the final EIS when they make decisions on the Project.
