<HD SOURCE="HED">SUPPLEMENTARY INFORMATION:</HD>
PHMSA received a special permit request from SNG, a subsidiary of Kinder Morgan, on December 27, 2023, seeking a waiver 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 changes from a Class 1 to Class 3 location.
The Cypress Line Pipeline segment is a 24-inch-diameter natural gas transmission pipeline, 0.176 miles in length, located in Chatham County, Georgia. The maximum allowable operating pressure for the Cypress Line Pipeline segment is 1,250 pounds per square inch gauge. This special permit is being requested to allow SNG to operate the Cypress Line Pipeline Segment 727 in a Class 3 location at its current operating pressure by implementing enhanced integrity management procedures in lieu of replacing pipe or lowering the operating pressure, as required by Part 192.
PHMSA previously published this request on April 24, 2024, with the public comment period closing on May 24, 2024. The special permit request letter, proposed special permit with conditions, environmental assessment (EA), and all other pertinent documents for the original special permit are available in Docket No. PHMSA-2023-0136 in the Federal Docket Management System located at
<E T="03">www.regulations.gov.</E>
Following the closure of the comment period, PHMSA began reviewing its special permit process to determine if special permit conditions could be streamlined in order to ease unnecessary burdens on applicants. As part of that process, PHMSA gave SNG the option of seeking reconsideration of its application and conducting another round of public notice and comment. SNG exercised that option. As a result, the proposed conditions in this new version of the special permit have been revised from the version previously noticed.
Since the issuance of the original EA, on July 1, 2025, DOT published DOT Order 5610.1D: Procedures for Considering Environmental Impacts, which outlines DOT's processes and requirements for complying with NEPA under 42 U.S.C. 4321
<E T="03">et seq.</E>
PHMSA has incorporated the following Categorical Exclusion (CE) from DOT 5610.1D into its implementing procedures:
<E T="03">1. Granting, renewing, or denying a special permit related to waiving class location or odorization requirements, following the procedures set forth in 49 CFR 190.341, including the identification of any enforceable conditions, imposed pursuant to 49 CFR 190.341(d)(2), that are required to prevent and address pipeline safety and environmental risk.</E>
On August 13, 2025, Environmental Protection Specialists from PHMSA independently reviewed the special permit request for compliance with the National Environmental Policy Act (NEPA). Based on the scope of the action, PHMSA has further determined that no extraordinary circumstances apply. In order to ensure continued human and environmental safety, the operator must fulfill the mitigation conditions of the special permit; continue to employ good operating practices; and continue to follow any additional applicable permitting requirements, State laws, or other pre-existing Federal requirements related to environmental protection. Should conditions change, or should extraordinary circumstances materialize, the operator must contact PHMSA for reevaluation. The proposed action is hereby categorically excluded from further NEPA review. The finalized CE will be published at
<E T="03"> https://www.phmsa.dot.gov/planning-and-analytics/environmental-analysis-and-compliance/implementing-procedures.</E>
The website also includes information on DOT Order 5610.1D.
The special permit request and revised proposed special permit with conditions for the above-listed SNG pipeline segment are available for review and public comment in Docket No. PHMSA-2023-0136. PHMSA invites interested persons to review and submit comments on the special permit request and proposed special permit with conditions in the docket. 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.
