Crews working for the London-based energy company BP have excavated more than 100 feet of the Olympic Pipeline near Everett, Washington, but have yet to identify the source of a refined product leak that has kept the crucial fuel line shut down for nearly two weeks.

The ongoing disruption has prompted Washington Governor Bob Ferguson to declare an emergency following the widespread disruptions caused by the shutdown. 

The shutdown has significantly impacted jet fuel deliveries to Seattle-Tacoma International Airport (Sea-Tac), which is dependent on the pipeline for a substantial portion of its supply.

In a statement released Friday, a BP spokesperson confirmed that excavation and inspection of the pipeline would continue overnight, noting that the line remains closed. The company provided no timeline for restarting the 400-mile system.

The pipeline, which runs from northern Washington down to Oregon, transports gasoline, diesel, and jet fuel throughout the region.

The initial leak was first reported on November 11. According to BP, crews briefly restored one of the two lines east of Everett earlier this week in an attempt to alleviate supply issues while the main investigation continued. 

However, the restored line was quickly shut down again, halting all refined product deliveries across the system once more.

Governor Ferguson’s emergency declaration, issued on Wednesday, acknowledges the supply chain crisis caused by the closure. 

The declaration allows the state to take necessary steps to maintain essential services and mitigate the economic impact of the fuel shortage across the region.
