Start Preamble

On June 30, 2020, Columbia Gulf Transmission, LLC (Columbia Gulf) filed an application in Docket No. CP20-490-000 requesting a Certificate of Public Convenience and Necessity, pursuant to Sections 7(b) and 7(c) of the Natural Gas Act, to abandon, replace, and operate certain natural gas pipeline facilities. The proposed project is known as the Mainline 300 Replacement Project (Project) and consists of the abandonment and replacement of two segments of the 36-inch-diameter Mainline 300 totaling approximately 775 feet. The Project is located in Menifee and Montgomery Counties, Kentucky. Due to increased population density in the area along certain discrete sections of Mainline 300, Columbia Gulf is required, pursuant to Part 192 of the U.S. Department of Transportation regulations to replace segments of its existing Mainline 300 pipeline to meet the Class 3 pipeline design requirements.

On July 9, 2020, the Federal Energy Regulatory Commission (Commission or FERC) issued its Notice of Application for the Project. Among other things, that notice alerted agencies issuing federal authorizations of the requirement to complete all necessary reviews and to reach a final decision on a request for a federal authorization within 90 days of the date of issuance of the Commission staff's Environmental Assessment (EA) for the Project. This instant notice identifies the FERC staff's planned schedule for the completion of the EA for the Project.

Schedule for Environmental Review

Issuance of EA—January 20, 2021

90-day Federal Authorization Decision Deadline—April 20, 2021

If a schedule change becomes necessary, additional notice will be provided so that the relevant agencies are kept informed of the Project's progress.

Project Description

The Project would involve the construction and operation of the following facilities:

  • Replacement of approximately 760 feet of existing 36-inch-diameter pipeline, with approximately 760 feet of new, 36-inch-diameter natural gas transmission pipeline from Milepost (MP) 6.8 to MP 6.9; and
  • Replacement of approximately 15 feet of existing 36-inch-diameter pipeline, with approximately 15 feet of new, 36-inch-diameter natural gas transmission pipeline from MP 6.9 to MP 6.9.


On July 31, 2020, the Commission issued a Notice of Intent to Prepare an Environmental Assessment for the Proposed Mainline 300 Replacement Project and Request for Comments on Environmental Issues (NOI). The NOI was sent to affected landowners; federal, state, and local government agencies; elected officials; environmental and public interest groups; Native American tribes; other interested parties; and local libraries and newspapers. In response to the NOI, the Commission did not receive any comments.Start Printed Page 63112
