If your comments responsive to this notice contain commercial or financial information that is customarily treated as private, that you treat as private, and that is relevant or responsive to this notice, it is important that you clearly designate the submitted comments as CBI. Pursuant to 49 Code of Federal Regulations (CFR) § 190.343, you may ask PHMSA to give confidential treatment to information you give to the agency by taking the following steps: (1) mark each page of the original document submission containing CBI as “Confidential”; (2) send PHMSA, along with the original document, a second copy of the original document with the CBI deleted; and (3) explain why the information you are submitting is CBI.

SUPPLEMENTARY INFORMATION:

PHMSA received a special permit request from CGT, a subsidiary of TC Energy, on March 27, 2024, seeking the addition of a new special permit segment to be incorporated into special permit PHMSA-2008-0066. The new segment request is a part of the active permit's special permit inspection area (SPIA #2). Special permit PHMSA-2008-0066 allows CGT to deviate from the Federal pipeline safety regulations in 49 CFR 192.611(a), (d), and 192.619(a), where a gas transmission pipeline segment has undergone a change from a Class 2 to a Class 3 location.

Special permit PHMSA-2008-0066 is active and was granted on July 21, 2021

1

and is effective until July 21, 2031 for 41 special permit segments, which include 146,027 feet (approximately 27.657 miles) of the CGT natural gas transmission pipeline system located in the state of Tennessee. The new special permit segment is requested for 7,900 feet (approximately 1.496 miles). If granted, the special permit segments would total 153,927 feet (approximately 29.153 miles).

Special Permit PHMSA-2008-0066 was originally issued on March 2, 2010 and renewed on July 21, 2021.

Upon receipt of this request, an Environmental Protection Specialist from PHMSA's Environmental Analysis and Compliance Division reviewed the Final Environmental Assessment (FEA) and its findings. In consideration of this, PHMSA finds that the expansion of the proposed special permit would not result in significant impacts to the human environment. Furthermore, the existing FEA and Finding of No Significant Impact remain adequate, pursuant to the National Environmental Policy Act of 1969, as amended (42 U.S.C. 4321

et seq.

). No further environmental assessment is required for this proposal.

CGT's new special permit segment request, active special permit with conditions, and FEA are available for review and public comment in Docket No. PHMSA-2008-0066. PHMSA invites interested persons to review and submit comments in the docket on the new special permit segment request. Please submit comments on any potential safety, environmental, and other relevant considerations implicated by the special permit request. Comments may include relevant data.

Before issuing a decision on the special permit request, PHMSA will evaluate all comments received on or before the comments closing date. PHMSA will consider each relevant comment it receives in making its decision to grant or deny this special permit request.

Issued in Washington, DC, on June 24, 2025 under authority delegated in 49 CFR 1.97.

Linda Daugherty,

Acting Associate Administrator for Pipeline Safety.
