Sable Offshore Corp. has resumed operations of a controversial California pipeline network for the first time in a decade, following an executive order from President Trump.  

The Houston-based company announced Monday that it has restored oil flow through the infrastructure spanning Santa Barbara, San Luis Obispo, and Kern counties, after the U.S. Energy Secretary Chris Wright invoked the Defense Production Act (DPA) on Friday.

The move marks a dramatic escalation in a jurisdictional battle between the Trump administration and California officials over energy policy and environmental safeguards.

The pipeline network, part of the Santa Ynez Unit, has been shuttered since 2015 when a corroded pipe burst, causing one of the worst oil spills in California history.

Justifying the move, President Trump and Energy Secretary Chris Wright argued that national energy security supersedes state regulations. 

California Gov. Gavin Newsom slammed the move, calling it an "illegal" attempt to restart a line whose operators face criminal charges and multiple court prohibitions.

The resumption comes despite a Saturday directive from the California Department of Parks and Recreation ordering Sable to "immediately remove the pipeline" from Gaviota State Park. The agency formally denied Sable’s operating application, citing the project’s incompatibility with protected lands.

In response, Sable filed a federal lawsuit Sunday seeking to confirm its right to operate under the presidential order.

"Sable Offshore is putting California consumers first by increasing the domestic supply of crude oil into the California market by approximately 17%," said Sable CEO Jim Flores. The company expects to begin sales by April 1 at a rate of 50,000 barrels per day.

Environmental groups, including the Center for Biological Diversity, called the use of the DPA a "radical and unprecedented" abuse of power, noting that the project remains the largest single source of greenhouse gas emissions in Santa Barbara County.

Following the resumption order, the California State Lands Commission held an emergency meeting Monday night to consider litigation regarding violations of federal consent decrees that previously delegated pipeline oversight to the state.
