The staff of the Federal Energy Regulatory Commission (FERC or Commission) will prepare an environmental assessment (EA) that will discuss the environmental impacts of the Trunkline Mainline Abandonment Project involving abandonment of facilities by Trunkline Gas Company, LLC (Trunkline) located in numerous counties in Illinois, Kentucky, Tennessee, Mississippi, Arkansas, Louisiana, and Texas. The Commission will use this EA in its decision-making process to determine whether the project is in the public convenience and necessity.

This notice announces the opening of the scoping process the Commission will use to gather input from the public and interested agencies on the project. Your input will help the Commission staff determine what issues they need to evaluate in the EA. Please note that the scoping period will close on November 26, 2012.

This notice is being sent to the Commission's current environmental mailing list for this project. State and local government representatives should notify their constituents of this proposed project and encourage them to comment on their areas of concern.

Trunkline provided landowners with a fact sheet prepared by the FERC entitled “An Interstate Natural Gas Facility On My Land? What Do I Need To Know?”. 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 also available for viewing on the FERC Web site (

Summary of the Proposed Project

Trunkline proposes to abandon by transfer to a corporate affiliate portions of its existing 100-1 and 100-2 looped [1] pipeline systems and portions of compressor stations (CS) located in numerous counties in Illinois, Kentucky, Tennessee, Mississippi, Arkansas, Louisiana, and Texas, so that they may be converted to the transmission of crude oil. Trunkline also proposes to abandon in-place 12 compressor units totaling 15,850 horsepower (hp) that are no longer needed. Trunkline states that the abandonment would result in the reduction of its certificated winter mainline capacity through the Independence CS from 1,555 thousand dekatherms per day (MDt/d) to 958 MDt/d, and the certificated capacity out of its Texas portion of its system through the Longville CS would be reduced from 1,109 MDt/d to 920 MDt/d. After abandonment, these gas volumes would continue to be transported using the 100-2 pipeline between the Kountze CS and Longville CS, and the 100-3 pipeline between the Longville CS and the Tuscola CS.

The Trunkline Mainline Abandonment Project would consist of the following:

  • Abandonment by transfer of 45.02 miles of the 24-inch-diameter 100-1 Loopline extending from Main Line Valve (MLV) 43-1 near Buna, Texas to the Longville CS near Longville, Louisiana;
  • Abandonment by transfer of 725.46 miles of the 30-inch-diameter 100-2 Loopline pipeline extending from the Longville CS to the Tuscola CS near Tuscola, Illinois;
  • Abandonment in-place of a 3,000-hp compressor unit from the Pollock CS (Louisiana); a 1,050-hp compressor unit from the Epps CS (Louisiana); four compressor units totaling 4,200 hp from the Shaw CS (Mississippi); five compressor units totaling 5,250 hp from the Independence CS (Mississippi); and a 2,350-hp compressor unit from the Joppa CS (Illinois); and
  • Abandonment of minor facilities at 163 sites across the systems, 80 of which would require ground disturbing activities.

Trunkline states that upon the grant of abandonment authority for the above facilities, its Mainline pipeline and existing compressor stations would continue to operate in interstate transportation service.

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

Non-Jurisdictional Facilities

Following transfer of the facilities, the future operator of the abandoned pipeline would perform activities that are not under the jurisdiction of the FERC (non-jurisdictional) including modification of the facilities to transport crude oil. The future operator would modify the facilities proposed for abandonment at 95 sites. These activities would include:

  • Removal and/or change out of mostly MLVs at 84 sites that overlap the abandonment work sites;
  • Construction of four new MLVs;
  • Construction of three new relays totaling 4,400 feet to make the pipeline diameter consistent, in order to enable inline inspection tools to be run through the crude oil pipeline; and
  • Construction of replacement pipelines across the Sabine, Red, Mississippi, and Ouachita Rivers using the horizontal directional drilling method.

The scope of the non-jurisdictional pipeline construction activities is still being developed. However, the current scope includes:

  • Construction of about 33.6 miles of 30-inch-diameter pipeline from the vicinity of the tank farms in Patoka, Illinois to Trunkline's existing Johnsonville CS; and
  • Construction of about 154 miles of 30-inch-diameter pipeline from about milepost 62.7 near Alexandria, Louisiana to a possible delivery point in St. James, Louisiana.

These related non-jurisdictional facilities are not subject to the FERC's environmental review procedures. In the EA, we [3] will provide available descriptions of the non-jurisdictional facilities and include them under our analysis of cumulative impacts.

Land Requirements for Construction

Trunkline's abandonment activities would require ground disturbance of approximately 10.1 acres at 80 sites and would involve the following: excavation of cross-over pipeline segments for isolation of tap valve meter and regulators, installation of hot taps on the Mainline pipeline, excavation and removal of two drip lines on Loopline 100-2, removal of a small segment of pipeline from Loopline 100-1 downstream of Mainline Valve 43-1, and capping the ends of the pipe. Upon conclusion of the abandonment activities, the disturbed acreage would be restored. In addition, Trunkline would use other areas at existing mainline valve and compressor stations to disconnect above ground piping, welding caps on the pipeline ends, or installing blind flanges. These activities would involve no ground disturbance.

The EA Process

The National Environmental Policy Act (NEPA) 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, the Commission requests public comments on the scope of the issues to address in the EA. We will consider all filed comments during the preparation of the EA.

In the EA we will discuss impacts that could occur as a result of the abandonment of the proposed project under these general headings:

  • Geology and soils;
  • Land use;
  • Water resources, fisheries, and wetlands;
  • Cultural resources;
  • Vegetation and wildlife;
  • Air quality and noise;
  • Endangered and threatened species;
  • Public safety; and
  • Cumulative impacts.

We will also evaluate reasonable alternatives to the proposed project or portions of the project, and make recommendations on how to lessen or avoid impacts on the various resource areas.

The EA will present our independent analysis of the issues. The EA will be available in the public record through eLibrary. Depending on the comments received during the scoping process, we may also publish and distribute the EA to the public for an allotted comment period. We will consider all comments on the EA before making our recommendations to the Commission. To ensure we have the opportunity to consider and address your comments, please carefully follow the instructions in the Public Participation section below.

With this notice, we are asking agencies with jurisdiction by law and/or special expertise with respect to the environmental issues of this project to formally cooperate with us in the preparation of the EA.[4] Agencies that would like to request cooperating agency status should follow the instructions for filing comments provided under the Public Participation section of this notice.

Consultations Under Section 106 of the National Historic Preservation Act

In accordance with the Advisory Council on Historic Preservation's implementing regulations for section 106 of the National Historic Preservation Act, we are using this notice to initiate consultation with applicable State Historic Preservation Offices (SHPO), and to solicit their views and those of other government agencies, interested Indian tribes, and the public on the project's potential effects on historic properties.[5] We will define the project-specific Area of Potential Effects (APE) in consultation with the SHPOs as the project develops. On natural gas facility projects, the APE at a minimum encompasses all areas subject to ground disturbance (examples include construction right-of-way, contractor/pipe storage yards, compressor stations, and access roads). Our EA for this project will document our findings on the impacts on historic properties and summarize the status of consultations under section 106.
