The documents posted on this site are XML renditions of published Federal

The OFR/GPO partnership is committed to presenting accurate and reliable
regulatory information on FederalRegister.gov with the objective of
establishing the XML-based Federal Register as an ACFR-sanctioned
publication in the future. While every effort has been made to ensure that
the material on FederalRegister.gov is accurately displayed, consistent with
the official SGML-based PDF version on govinfo.gov, those relying on it for
legal research should verify their results against an official edition of
the Federal Register. Until the ACFR grants it official status, the XML
rendition of the daily Federal Register on FederalRegister.gov does not
provide legal notice to the public or judicial notice to the courts.

Confidential Business Information: Confidential business information (CBI) is commercial or financial information that is both customarily and treated as private by its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. 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. Unless you are notified otherwise, PHMSA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this notice. Submissions containing CBI should be sent to Lee Cooper, DOT, PHMSA-PHP-80, 1200 New Jersey Avenue SE, Washington, DC 20590-0001. Any commentary PHMSA receives that is not specifically designated as CBI will be placed in the public docket for this matter.

SUPPLEMENTARY INFORMATION:

On January 22, 2026, PHMSA received a special permit application from Sable requesting a waiver of the requirement in 49 CFR 195.452(h)(4)(iii)(H) to remediate certain longitudinal seam weld corrosion on hazardous liquid pipelines within 180 days of discovery. The waiver would apply to two segments of the Santa Ynez Pipeline System, an interstate hazardous liquid pipeline facility that transports crude oil produced on the Outer Continental Shelf through an onshore processing facility located in Santa Barbara County, California, to a terminal located in Kern County, California. The two segments that would be subject to the waiver are known as Lines CA-324 and CA-325 (including CA-325A and CA-325B). On February 24, 2026, PHMSA published a notice to solicit public comment on a request for a special permit submitted by Sable Offshore Corp. (Sable). The comment period is currently set to expire on March 26, 2026.

On March 13, 2026, the Secretary of Energy, acting under authority delegated ( printed page 13699) in Executive Order “Adjusting Certain Delegations Under the Defense Production Act,” directed Sable to restart transportation of crude oil on the pipeline segments subject to this special permit request pursuant to the Defense Production Act (DPA). PHMSA is issuing this notice to extend the comment period until 14 days after the date of this notice to give the public time to review the proposed special permit in light of the Secretary's recent action. In particular, PHMSA is soliciting public comments on any potential impact that the DPA order might have on this proceeding, including whether the special permit remains necessary and, if so, whether safety or environmental analysis should be adjusted in light of the restart of the pipeline segments.

At the conclusion of the extended comment period, PHMSA will review the comments received from this notice as part of its evaluation to grant or deny the special permit request.

Issued in Washington, DC, under authority delegated in 49 CFR 1.97.

Linda Daugherty,

Acting Associate Administrator for Pipeline Safety.
