Take notice that on August 27, 2025, Tennessee Gas Pipeline Company, L.L.C. (Tennessee) requested that the Commission grant an extension of time, until December 31, 2027, to construct and place into service its 507G Line Abandonment Project (Project) located in Acadia, Vermilion, Iberia, and St. Mary Parishes, Louisiana as authorized in the Order Approving Abandonment (Order). [^1] The Order required Tennessee to complete abandonment of the facilities within one year of the date of the Order, or by July 24, 2026.
[^1]*Tennessee Gas Pipeline Company, L.L.C.,* 192 FERC ¶ 61,079 (2025).
Tennessee states that it is in the process of obtaining permits needed to start the abandonment activities, but it needs more time than originally anticipated to obtain them and to coordinate with landowners to avoid unnecessary crop damage, and to implement measures to protect threatened and endangered species.
This notice establishes a 15-calendar day intervention and comment period deadline. Any person wishing to comment on Tennessee's request for an extension of time may do so. No reply comments or answers will be considered. If you wish to obtain legal status by becoming a party to the proceedings for this request, you should, on or before the comment date stated below, file a motion to intervene in accordance with the requirements of the Commission's Rules of Practice and Procedure (18 CFR 385.214 or 385.211) and the Regulations under the Natural Gas Act (NGA) (18 CFR 157.10).
As a matter of practice, the Commission itself generally acts on requests for extensions of time to complete construction for NGA facilities when such requests are contested before order issuance. For those extension requests that are contested, [^2] the Commission will aim to issue an order acting on the request within 45 days. [^3] The Commission will address all arguments relating to whether the applicant has demonstrated there is good cause to grant the extension. [^4] The Commission will not consider arguments that re-litigate the issuance of the certificate order, including whether the Commission properly found the project to be in the public convenience and necessity and whether the Commission's environmental analysis for the certificate complied with the National Environmental Policy Act (NEPA). [^5] At the time a pipeline requests an extension of time, orders on certificates of public convenience and necessity are final and the Commission will not re-litigate their issuance. [^6] The Director of the Office of Energy Projects, or his or her designee, will act on all of those extension requests that are uncontested.
[^2] Contested proceedings are those where an intervenor disputes any material issue of the filing. 18 CFR 385.2201(c)(1).

[^5] Similarly, the Commission will not re-litigate the issuance of an NGA section 3 authorization, including whether a proposed project is not inconsistent with the public interest and whether the Commission's environmental analysis for the permit order complied with NEPA.
