**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 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.

Acting Associate Administrator for Pipeline Safety.
