Start Preamble March 8, 2006.

The staff of the Federal Energy Regulatory Commission (FERC or Commission) will prepare an environmental assessment (EA) that will discuss the environmental impacts of Southern Natural Gas Company's (Southern) application for its 2006 Abandonment and Replacement Project. Southern proposes to abandon, replace and modify facilities associated with its 22-inch North Main Loop Line and abandon its Pell City Compressor Station Unit No. 3 as part of an extensive pipeline integrity program. Pipeline changes would occur on Southern's existing system in Tuscaloosa County, Alabama. Abandonment of a compressor station would occur in St. Clair County, Alabama.

This notice announces the opening of the scoping period that will be used to gather environmental input from the public and interested agencies on the project. Scoping comments are requested by April 10, 2006.

With this notice, the staff of the FERC is asking other Federal, State, local and tribal agencies with jurisdiction and/or special expertise with respect to environmental issues to cooperate with us in the preparation of the EA. These agencies may choose to participate once they have evaluated Southern's proposal relative to their responsibilities. Agencies that would like to request cooperating status should follow the instructions for filing comments described in Appendix 1.

This notice is being sent to potentially affected landowners; Federal, state, and local government agencies; elected officials; environmental and public interest groups; Native American Tribes, other interested parties; local libraries and newspapers. State and local government representatives are asked to notify their constituents of this planned project and encourage them to comment on their areas of concern.

If you are a landowner receiving this notice, you may be contacted by a pipeline company representative about the acquisition of an easement to construct, operate, and maintain the proposed facilities. The pipeline company would seek to negotiate a mutually acceptable agreement. However, if the project is approved by the Commission, that approval conveys with it the right of eminent domain. Therefore, if easement negotiations fail to produce an agreement, the pipeline company could initiate condemnation proceedings in accordance with state law.

A fact sheet prepared by the FERC entitled “An Interstate Natural Gas Facility On My Land? What Do I Need To Know?” is available for viewing on the FERC Web site ( This fact sheet addresses a number of typically asked questions, including the use of eminent domain and how to participate in the Commission's proceedings. It is available for viewing on the FERC Internet Web site (


Pipeline Abandonment, Replacement and Modification

Southern's 22-inch McConnells North Main Loop Line, which is part of its North Main Line System in Tuscaloosa County, Alabama, was commissioned in 1946 and is proposed for retirement as part of the application. Because of a reduction in contracted capacity in this area due to capacity turnback and capacity shift, this section of the line is no longer needed. However, to continue to provide reliable and safe gas supplies to the western Alabama region, Southern proposes to replace a section of the abandoned 22-inch McConnells North Main loop Line by extending the existing 24-inch 2nd North Main Loop Line.

Compressor Station Abandonment

The Pell City Compressor Station was built in 1989 to deliver firm contract volumes on the Gadsden Lateral Line. Since the Gadsden Lateral Line has not been operating at full contract capacity, the Pell City Unit No. 3 has not been required to deliver peak day demand on the Gadsden Lateral Line. Recent capacity turnback on the Gadsden Lateral Line makes it possible to abandon the Pell City Unit No. 3 since it is no longer required to meet firm peak day requirements.

Summary of the Proposed Project

Tuscaloosa, Alabama

  • Abandon in place 4.55 miles of the McConnells 22-inch North Main Loop Segment from Milepost 260.74 to Milepost 265.29. This portion of the McConnells North Main Loop Segment would be pigged, filled with nitrogen, and capped before being abandoned in place.
  • Abandon and remove 6.36 miles from Milepost 265.29 to Milepost 271.65. Southern proposes to remove all pipeline and associated piping assemblies along this 6.36 mile route, with the exception of the North River crossing at Milepost 269.45 and any uncased road crossings. The uncased road crossing would be cut and capped on each side of the road crossing and filled with grout for abandonment in place. The cased road crossings that are left void would also be filled with grout and abandoned in place. Start Printed Page 13381
  • Install a new anchor block and blowoff/crossover assembly at Milepost 271.65, and, if necessary, continue maintenance by installing sleeves on coupled joints from Milepost 271.65 to Milepost 271.73.
  • Extend its 24-inch 2nd North Main Loop Line by constructing, installing and operating 6.1 miles of 24-inch pipeline from Milepost 142.6 to Milepost 148.7 (Tuscaloosa County, Alabama). This segment of the 24-inch 2nd North Main Loop Line is parallel to Milepost 265.3 to Milepost 271.6 of the 22-inch North Main Loop Line, which is proposed to be abandoned above. Installation of the proposed 2nd North Main Loop Segment would be within the same location and same ditch line as Southern's 22-inch North Main Loop Line after the abandonment and removal of the 6.36 miles described above.
  • Connect the proposed 2nd North Main Loop Segment to the existing 24-inch 2nd North Main Loop Line by removing the existing weld cap and making a tie-in at Milepost 142.56. It would also be necessary to install a new blowoff/crossover assembly at Milepost 148.93, which would be connected to the crossover assembly installed at Milepost 271.65 on the 22-inch North Main Loop Line as detailed above.

St. Clair County, Alabama

  • Abandon in place its Pell City Compressor Station Unit No. 3 (St. Clair County, Alabama) at Milepost 352.8 on Southern's North Main and North Main Loop Lines. All existing gas piping systems would be disconnected including fuel gas and blind flanges would be installed at these points. Additionally, electric power would be disconnected from the unit such that all control systems would be inoperable. The unit would then be purged with nitrogen and prepared for long term storage in place.

The location of the project facilities is shown in Appendix 2.[1]

Land Requirements

Abandonment, replacement and modification of the proposed facilities would require the temporary disturbance of about 105.24 acres of land, the majority of which is within Southern's existing 100-foot right-of-way. Additional extra work spaces of 10.32 acres) would be required at road and waterbody crossings.

Following construction, permanent land acquisition of 0.16 acres would be maintained as part of the right-of-way for the maintenance of the 24-inch 2nd North Main Loop Line Replacement section. The remaining acreage required during construction would be restored and allowed to revert to its former land uses.

The EA Process

We [2] are preparing this EA to comply with the National Environmental Policy Act (NEPA) which requires the Commission to take into account the environmental impacts that could result from an action whenever it considers the issuance of a Certificate of Public Convenience and Necessity. NEPA also requires us to discover and address concerns the public may have about proposals. This process is referred to as “scoping.” The main goal of the scoping process is to focus the analysis in the EA on the important environmental issues. By this Notice of Intent, the Commission staff requests public comments on the scope of the issues to address in the EA. All comments received are considered during the preparation of the EA. By this notice, we are also asking Federal, state, and local agencies with jurisdiction and/or special expertise with respect to environmental issues to formally cooperate with us in the preparation of the EA. Agencies that would like to request cooperating status should follow the instructions for filing comments below.

Our independent analysis of the issues will be in the EA. Depending on the comments received during the scoping process, the EA may be published and mailed to Federal, state, and local agencies, public interest groups, interested individuals, affected landowners, newspapers, libraries, and the Commissions official service list for this proceeding. A comment period will be allotted for review if the EA is published. We will consider all comments on the EA before we make our recommendations to the Commission.

Currently Identified Environmental Issues

In the EA, we will discuss impacts that could occur as a result of the construction and operation of the project. We will also evaluate reasonable alternatives to the proposed project or portions of the project.

We have already identified several issues that we think deserve attention based on a preliminary review of the proposed facilities and the environmental information provided by Southern. This preliminary list of issues may be changed based on your comments and our analysis.

Project-related impact on:

  • 7 residences/structures within 50 feet of the construction workspace.
  • 1 active private well within 32 feet of the construction workspace.
  • 2.6 acres of upland forest.
  • Four federally-listed threatened and endangered species potentially in the project area.
  • 9 emergent wetland crossings 3.5 acres.
  • 23 water body crossings.
  • Road crossings.
