The $2.3bn+ Sable oil pipeline restart in California has been blocked despite the project having President Trump’s backing. The Trump administration is eager to restart oil pipelines off California’s Central Coast. However, the judge noted that the recent executive order does not override state regulations concerning oil operations. It remains unclear exactly what effect the ruling may have on pipeline operator Sable Offshore Corp.
The firm has been marred in various legal challenges from California authorities. Environmental groups, however, celebrated the ruling as a “win for the rule of law.” Moreover, Governor Gavin Newsom called it a “rebuke of the Trump administration and Sable’s ploy to illegally use emergency powers to bypass state laws.”
Last month, the Trump administration invoked the Defense Production Act when it directed Sable to commence operations. It was mandated to send crude flowing through a network of undersea and on-land oil lines. The administration argued that the order preempted several California laws, regulations and court orders. These riles had for months blocked the pipeline’s restart. Trump has been fundamental in implementing oil pipeline projects such as the contentious NESE pipeline project in New York. The project had also been paused following state altercations on its development.
Outlook on the Sable Oil Pipeline Restart in California
In the recent ruling, preliminary injunctions issued last summer were upheld against Sable, hindering the oil pipeline restart in California. Furthermore, it prohibited the pipeline system’s restart until the Houston-based company adheres to all state and local regulations. “Nothing … permits a party subject to a [Defense Production Act] order to violate other laws,” Geck wrote in the ruling. She cited case law from two other similar federal court decisions, which “strongly implies that the [Defense Production Act] order, by itself, does not permit the violation of applicable state regulatory law.”
Experts say Geck’s ruling could signal how other judges — including in upcoming federal court cases — may rule on the Trump administration’s push to restart the pipelines. Conversely, Sable has repeatedly clashed with state and local regulators as it has worked to restart the pipelines. The lines run through Santa Barbra, San Luis Obispo and Kern counties. However, they are linked to three offshore oil rigs.
Trump administration officials have rushed to support the project. They argue it will increase domestic oil production, especially as gas prices soar because of the war with Iran. The lines had sat unused since 2015, when a pipe rupture caused one of the state’s largest oil spills. Much about the project, however, remains tied up in legal challenges.
