Start Preamble November 17, 2006.

The staff of the Federal Energy Regulatory Commission (FERC or Commission) will prepare an environmental impact statement (EIS) that discusses the environmental impacts of the High Plains Expansion Project (project) involving construction and operation of by Colorado Interstate Gas Company (CIG) in Weld, Morgan, and Adams Counties, Colorado. These facilities would consist of about 170 miles of 24-inch and 30-inch-diameter pipeline in four separate pipeline segments. The EIS will be used by the Commission in its decision making process to determine if the project is in the public convenience and necessity.

The project is currently in the preliminary stages of design and at this time a formal application has not been filed with the Commission. For this project, the Commission is initiating the National Environmental Policy Act (NEPA) review prior to receiving the formal application. This pre-filing process allows interested stakeholders to become involved early in the project planning and to identify and resolve issues before a formal application is filed with the FERC. A docket number (PF06-36-000) has been established to place information filed by CIG and related documents issued or received by the Commission, into the public record.[1] Once a formal application is filed with the FERC, a new docket number will be established.

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. Please note that the scoping period will close on January 6, 2007. Details on how to submit comments are provided in the Public Participation section of this notice.

This notice is being sent to potentially affected landowners along the Project route; federal, state, and local government agencies; elected officials; environmental and public interest groups; Native American tribes; and local libraries and newspapers.

With this notice, we [2] are asking federal, state, and local agencies with jurisdiction and/or special expertise with respect to environmental issues to cooperate with us in the preparation of the EIS. These agencies may choose to participate once they have evaluated the proposal relative to their responsibilities. Agencies which would like to request cooperating status should follow the instructions for filing comments described later in this notice. We encourage government representatives to notify their constituents of this planned project and encourage them to comment on their areas of concern.

Some affected landowners may be contacted by a project representative about the acquisition of an easement to construct, operate, and maintain the proposed pipeline. If so, the company should seek to negotiate a mutually acceptable agreement. In the event that the Project is certificated by the Commission, that approval conveys the right of eminent domain for securing easements for the pipeline. Therefore, if easement negotiations fail to produce an agreement, the 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?” 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 (

Summary of the Proposed Project

CIG is proposing to expand its existing pipeline system along Colorado's Front Range in order to provide additional transportation services to this rapidly growing market. Specifically, CIG is proposing to construct approximately 170 miles of 24-inch and 30-inch-diameter pipeline in four separate pipeline segments in Weld, Morgan, and Adams Counties, Colorado as described below. The general locations of the proposed pipelines are shown in the figure included as Appendix 1 [3] .

The Project consists of the following facilities:

  • Line 250A—64.5 miles of 30-inch-diameter pipe and 20.5 miles of 24-inch-diameter pipe and 2 interconnect meter station facilities;
  • Line 251A—58 miles of 24-inch-diameter pipe and 2 interconnect meter station facilities;
  • Line 252A—14.9 miles of 30-inch-diameter pipe and 1 interconnect meter station facility;
  • Line 253A—6.1 miles of 24-inch-diameter pipe and 2 interconnect meter station facilities;
  • Seven new meter stations and eighteen new block valves; and
  • Pig launcher/receivers at the beginning and ending of the four new pipeline segments.

The entire project when completed would carry a total capacity of approximately 874,000 decatherms of gas per day. CIG is requesting approval such that the facilities are completed and put into service by August 2008. CIG proposes to begin construction in February 2008.

Land Requirements for Construction

CIG would use a typical 100-foot-wide construction right-of-way for the project. Additional work area would be required at certain feature crossings (e.g., waterbodies, wetlands, roads, and railroad crossings), staging areas, pipe yards, contractor's yards, and widening of certain access roads.

Based on preliminary information, it is estimated that construction of the proposed facilities would disturb about 2,000 acres of land. Of the 2,000 acres, about 1,000 acres would be temporary disturbed and about 1,000 acres would be permanently maintained for operation of the pipeline within a 50-foot-wide permanent right-of-way, and as aboveground facility sites.

Following construction, all temporary workspaces would be restored and allowed to revert to its former use.

The EIS Process

The FERC will be the lead federal agency for the preparation of the EIS. Start Printed Page 68602NEPA requires the FERC to take into account the environmental impacts that could result from an action when it considers whether or not an interstate natural gas pipeline should be approved. The Commission will use the EIS to consider the environmental impacts that could result if the project is authorized under section 7 of the Natural Gas Act. NEPA also requires us to identify and address concerns the public may have about proposals to be considered by the Commission. This process is referred to as “scoping.” The main goal of the scoping process is to focus the analysis in the EIS on important environmental issues and reasonable alternatives. By this Notice of Intent (NOI), the Commission staff requests agency and public comments on the scope on the issues to be addressed in the EIS. All comments received will be considered during the preparation of the EIS.

Although no formal application has been filed, the FERC Staff have already initiated a NEPA review under the FERC's Pre-Filing Process, which was established in Docket No. PF06-36-000. The purpose of the Pre-Filing Process is to seek public and agency input early in the project planning phase and encourage involvement by interested stakeholders in a manner that allows for the early identification and resolution of environmental issues. As part of the Pre-Filing Process review, FERC staff representatives will participate in an interagency scoping meeting in the project area to solicit comments and concerns about the project from other jurisdictional agencies.

With this notice, the Commission requests federal, state, and local government agencies with jurisdiction and/or special expertise with the respect to environmental issues to express their interest in becoming cooperating agencies for the preparation of the EIS. These agencies may choose to participate once they have evaluated the proposal relative to their responsibilities. Agencies that would like to request cooperating status should send a letter expressing that interest and expected level of involvement to the Secretary of the Commission at the address provided in the public participation section of this notice.

The FERC's independent analysis of the issues will be included in a draft EIS. The draft EIS will be mailed to federal, state, and local government agencies; elected officials; environmental and public interest groups; Native American tribes; affected landowners; other interested parties; local libraries and newspapers; and the FERC's official service list for this proceeding. A comment period will be allotted for review of the draft EIS. We will consider all timely comments on the draft EIS and revise the document, as necessary, before issuing a final EIS.
