Final Environmental Impact Statement


Final Environmental Impact Statement for the Leach XPress and Rayne XPress Expansion Projects (Docket Nos. CP15-514-000 and CP15-539-000)
Issued: September 1, 2016

The staff of the Federal Energy Regulatory Commission (Commission or FERC) has prepared a final environmental impact statement (EIS) for the Leach XPress and Rayne XPress Expansion Projects (or Projects).

The Leach XPress Project proposed by Columbia Gas Transmission, LLC (Columbia Gas) includes a total of approximately 160 miles of new 20- to 36-inch-diameter pipeline, three new compressor stations, modifications at two existing compressor stations, three new regulator stations, modifications at one existing regulator station, 13 bi-directional pig launcher and/or receiver facilities1, nine mainline valves, and five new odorization stations in Pennsylvania (Greene County), Ohio (Fairfield, Hocking, Jackson, Lawrence, Monroe, Morgan, Muskingum, Noble, Perry and Vinton Counties) and West Virginia (Marshall and Wayne Counties). The Leach XPress Project would also include the abandonment in-place of 28.2 miles of an existing 20-inch-diameter natural gas pipeline, beginning at the existing Crawford Compressor Station in Fairfield County, Ohio and traversing south to Hocking County, Ohio before terminating at the existing McArthur Regulator Station in Vinton County, Ohio.

The Rayne XPress Expansion Project proposed by Columbia Gulf Transmission, LLC (Columbia Gulf) would involve the construction and operation of the new Grayson Compressor Station in Carter County, Kentucky, the new Means Compressor Station in Menifee and Montgomery Counties, Kentucky, and modification of the existing Means Measurement and Regulation Station in Montgomery County, Kentucky.

The EIS has been prepared in compliance with the requirements of the National Environmental Policy Act (NEPA), the Council on Environmental Quality regulations for implementing NEPA (40 Code of Federal Regulations [CFR] 1500Ė1508), and FERC regulations implementing NEPA (18 CFR 380).

The conclusions and recommendations presented in the EIS are those of the FERC environmental staff. Input from the following cooperating agencies, including the U.S. Environmental Protection Agency, the U.S. Army Corps of Engineers (COE), the U.S. Fish and Wildlife Service (FWS), the Kentucky Department of Environmental Protection, the Ohio Environmental Protection Agency, the Pennsylvania Department of Conservation and Natural Resources and Department of Environmental Protection, and the West Virginia Division of Natural Resources and Department of Environmental Protection was considered during the development of our conclusions and recommendations. However, these agencies could develop their own conclusions and recommendations and would adopt the final EIS per 40 CFR 1506.3 (where applicable) if, after an independent review of the document, they conclude that their permitting requirements have been satisfied.

We determined that construction and operation of Columbia Gasí LX Project would result in some adverse environmental impacts. These impacts would occur during both construction and operation of the Project on vegetation, aquatic resources, wetlands, and wildlife as discussed in Section 4. However, if the proposed Project is constructed and operated in accordance with applicable laws and regulations, the mitigating measures discussed in this final EIS, and our recommendations, these impacts would be reduced to less than significant levels. Forest clearing resulting from the LX Project would result in significant impacts; however, due to the expected regrowth of these forests outside the permanent right-of-way and Columbia Gasís proposed mitigation, we conclude that the permanent conversion of forested land would be reduced to less than significant levels. This conclusion is based on a review of the information provided by Columbia Gas and Columbia Gulf and further developed from environmental information requests, field reconnaissance, scoping, literature research, alternatives analyses, and contacts with federal, state, and local agencies, Native American tribes, and other stakeholders. Although many factors were considered in this determination, the principal reasons are:

  • the Projects would minimize impacts on natural and cultural resources during construction and operation by implementing Columbia Gasí and Columbia Gulfís project-specific Environmental Construction Standards (which incorporates FERCís Upland Erosion Control, Revegetation, And Maintenance Plan and FERCís Wetland and Waterbody Construction and Mitigation Procedures), Spill Prevention, Containment and Control Plan, Winter Construction Plan, Horizontal Directional Drill Contingency Plan, Unanticipated Discoveries and Emergency Procedures, Procedure Guiding the Discovery of Unanticipated Cultural Resources and Human Remains, Blasting Plan, Traffic Control Plan, Longwall Mining Plan, and Fugitive Dust Control Plan.


  • We would complete Endangered Species Act consultation under Section 7 with the U.S. Fish and Wildlife Service prior to allowing any construction to begin.


  • We would complete the process of complying with Section 106 of the National Historic Preservation Act and implementing the regulations at 36 CFR 800 prior to allowing any construction to begin.


  • Columbia Gas and Columbia Gulf would be required to obtain applicable permits and provide mitigation for unavoidable impacts on waterbodies and wetlands through coordination with the U.S. Army Corps of Engineers and applicable state agencies.


  • We are recommending that Columbia Gas finalize a Migratory Bird Conservation Plan that includes documentation of its consultation with the U.S. Fish and Wildlife Service regarding avoidance, minimization, and mitigation measures.


  • We would provide oversight of an environmental inspection and mitigation monitoring program that would ensure compliance with all mitigation measures that become conditions of FERC authorizations and other approvals.


In addition, FERC staff developed other site-specific mitigation measures that Columbia Gas and Columbia Gulf should implement to further reduce the environmental impacts that would otherwise result from construction of the Projects.

The FERC Commissioners will take into consideration staffís recommendations when they make a decision on the individual Projects.
