Energy Secretary orders Houston-based Sable Offshore to restore California operations, escalating federal-state dispute over pipeline oversight

Federal directive targets stalled restart of Santa Ynez Unit and Las Flores Pipeline System

The U.S. energy secretary has directed Houston-headquartered Sable Offshore Corp. to restore operations tied to the Santa Ynez Unit, an offshore oil complex in federal waters off Santa Barbara County, California. The directive centers on resuming production and associated pipeline activity that has been largely dormant since the 2015 Refugio-area spill and the shutdowns that followed.

The order arrives amid overlapping disputes about safety oversight and jurisdiction for the Las Flores Pipeline System, which includes onshore lines that traverse Santa Barbara and Kern counties and connect offshore production to onshore processing and onward transport.

Background: a restart effort shaped by the 2015 spill and a 2020 consent decree

The Santa Ynez Unit includes three offshore platforms—commonly identified as Hondo, Harmony and Heritage—along with offshore pipelines, the onshore Las Flores Canyon processing facilities, and onshore pipeline segments. The system has been the focus of a prolonged restart campaign since Sable acquired the assets from ExxonMobil in early 2024.

The 2015 pipeline rupture near Refugio State Beach prompted a broad regulatory response and litigation that culminated in a 2020 federal consent decree. That decree established conditions for restarting the pipeline system, and it has remained central to subsequent disputes over which regulator has authority to sign off on a restart and what approvals are required.

Key legal and regulatory fault line: state oversight versus federal preemption

California officials have argued the state retains authority over the onshore pipeline segments and related environmental and coastal approvals. Federal officials have advanced a different theory: that the onshore Las Flores Pipeline qualifies as an interstate pipeline because it begins at federal offshore platforms and connects inland, shifting primary safety jurisdiction to federal pipeline regulators.

In January 2026, California filed suit challenging federal approval steps that would enable the pipeline restart. The state’s complaint framed the dispute as one of regulatory authority and public safety for hazardous infrastructure running through coastal and inland communities.

Defense Production Act becomes part of the federal strategy

In early March 2026, the Justice Department’s Office of Legal Counsel issued a memorandum addressing whether a presidential order under the Defense Production Act could preempt conflicting state laws and compel resumed operations connected to the Santa Ynez Unit and pipeline system. The opinion concluded that an order issued under congressionally delegated authority may carry the force of federal law under the Supremacy Clause and could preempt contrary state restrictions.

What happens next

• Litigation remains active in multiple venues, including challenges linked to state pipeline safety requirements, coastal permitting disputes, and federal-state jurisdictional claims.

• Regulators have also sought public input on aspects of the pipeline restart process, underscoring that the legal pathway and compliance obligations are still contested.

• Sable has separately examined alternatives to moving crude through the onshore pipeline system, including offshore storage and tanker-based transport strategies, which would raise additional permitting and oversight questions.

The directive intensifies a high-stakes conflict over whether federal emergency and national-security authorities can override California’s regulatory framework for restarting long-idled coastal oil infrastructure.

For Houston’s energy sector, the dispute places a locally headquartered operator at the center of a national debate over emergency authorities, pipeline safety governance, and the limits of state control when oil production occurs in federal waters but depends on coastal and inland infrastructure to reach market.
