**SUPPLEMENTARY INFORMATION:**
PHMSA received a special permit request from Portland Natural Gas Transmission System (PNGTS) on March 27, 2024, seeking the addition of a new special permit segment and, on April 16, 2024, seeking a special permit segment extension to be incorporated into special permit PHMSA-2006-24058. Both the new segment and extension request are a part of the active permit's special permit inspection area. Special permit PHMSA-2006-24058 allows PNGTS 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 1 to a Class 3 location.
Special permit PHMSA-2006-24058 is active and was granted on May 22, 2023; [^1] it is effective until May 22, 2033 for four special permit segments, which include 9,905 feet (approximately 1.876 miles) of the PNGTS natural gas transmission pipeline system located in the States of Maine and New Hampshire. The new special permit segment is requested for 2,625 feet (approximately 0.497 miles). The special permit segment extension is requested for an additional 4,678 feet (approximately 0.886 miles). If granted, the special permit segments would total 17,208 feet (approximately 3.259 miles).
[^1] Special Permit PHMSA-2006-24058 was originally issued on December 17, 2007 and renewed on May 22, 2023.
The active special permit segment, requested new special permit segment, and requested extension, are as follows:
| SPS No. | Status | County, state | Outside | Line name | Length | Year | Maximum |
| --- | --- | --- | --- | --- | --- | --- | --- |
| 2 | Active Segment | Cumberland, ME | 24 | PNGTS Mainline | 4,766 | 1998 | 1,440 |
| | Extension | Cumberland, ME | 24 | PNGTS Mainline | 4,678 | 1998 | 1,400 |
| 5 | New Segment | Cumberland, ME | 24 | PNGTS Mainline | 2,625 | 1999 | 1,440 |
Upon receipt of this request, PHMSA reviewed the final environmental assessment (FEA) and 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.
PNGTS's new special permit segment and extension request, active special permit with conditions, and FEA are available for review and public comment in Docket No. PHMSA-2006-24058. PHMSA invites interested persons to review and submit comments in the docket on both the special permit segment extension request and 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. Comments received after the closing date will be evaluated if it is possible to do so without incurring additional expense or delay. 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 October 1, 2025 under authority delegated in 49 CFR 1.97.

Acting Associate Administrator for Pipeline Safety.
