Key Takeaways:

Repair crews have located the leak in Washington state's Olympic Pipeline, and one segment has been restarted, restoring crucial jet fuel supply to Seattle-Tacoma (KSEA) and Portland International (KPDX) airports.
Airlines are returning to normal operations, discontinuing temporary fuel stops and alternative delivery methods that were implemented during the pipeline shutdown.
While the 16-inch pipeline segment is flowing, a leak in the 20-inch segment has been confirmed and still requires repair.
The Olympic Pipeline Company and BP Pipelines recently faced a $3.8 million fine for a separate 2023 gasoline spill from the same pipeline system.

Repair crews in Washington state have found the location of the leak in the Olympic Pipeline—and it is flowing again.

That’s good news for the airlines operating out of Seattle-Tacoma International (KSEA) and Portland International (KPDX) airports. Since the discovery of the leak and the subsequent shutdown of the pipes, the facilities have relied on tankering in fuel or adjusting the routes to allow for refueling stops.
