The U.S. Court of Appeals for the Ninth Circuit has not yet ruled on the merits of the challenge to PHMSA’s assertion of exclusive Federal jurisdiction over Sable Offshore Corp.’s Las Flores (Santa Ynez) pipeline segments (CA-324 and CA-325) or related restart approvals. A three-judge panel ordered additional briefing after a status conference, and a decision is expected to take months.
The 9th Circuit panel held a video status conference on 10/5/2026, and consolidated petitions from the Environmental Defense Center (and other groups) and the State of California. The panel ordered further briefing rather than issuing an immediate decision on the core jurisdictional question—whether the onshore pipeline segments engage in “interstate commerce” under the Pipeline Safety Act (making them subject to exclusive PHMSA authority rather than California’s Office of the State Fire Marshal).
Concise background summary from Grok: PHMSA reclassified the pipelines as interstate in late 2025 (asserting jurisdiction because they transport crude from Outer Continental Shelf platforms through California to a Kern County terminal, with arguments that onshore processing does not break the flow of interstate commerce). This enabled restart approvals and special permits (initially emergency, later a longer-term one) that environmental groups and California challenge as unlawful, preemptive of state authority, and deficient under the Pipeline Safety Act, NEPA, and ESA. Sable restarted operations earlier in 2026 amid related litigation (including Defense Production Act issues and consent-decree matters in district court). The Ninth Circuit cases are Environmental Defense Center et al. v. PHMSA (No. 25-8059) and the consolidated California petition (originally No. 26-508 / related Nos.).











Comments from the California AG and Sable Offshore on the special permit application to PHMSA

I’m attaching the complete comment letters from Sable Offshore and their main antagonist, California Attorney General Bonta, in response to PHMSA’s public notice and request for comments on Sable’s special permit application.
Summary of the California AG’s assertions:
“First, PHMSA is without authority to grant such a special permit because Lines CA-324/325 are intrastate pipelines and California regulators have sole regulatory oversight over any attempt to restart these Lines and issue state waivers. Second, California has vested interests in ensuring Lines CA-324/325 operate safely and PHMSA’s proposed special permit would dilute the higher state safety standards that were imposed on Sable and therefore it is inconsistent with pipeline safety. 49 C.F.R. § 190.341(d). Third, given the fact Line CA-324 already failed and caused a catastrophic oil spill in 2015 in Santa Barbara County, even if PHMSA had authority to issue a special permit (which it does not), a more robust environmental analysis needs to be performed. Fourth, PHMSA unlawfully invokes the Endangered Species Acts’s emergency consultation procedures and has given no indication that it will consult with the National Marine Fisheries Service, in violation of the Act. Finally, Secretary Wright’s March 13, 2026, order (“DPA
Order”) does not change anything about the propriety of the Application, because the DPA Order itself is unlawful.”
