• BP confirms leak in 20-inch segment, repairs planned
• Washington and Oregon declared fuel emergency due to closure
• Shutdown disrupted fuel supplies to Seattle-Tacoma Airport

NEW YORK, Nov 25 (Reuters) - BP (BP.L) , opens new tab said on Tuesday it had partially restarted the 400-mile Olympic Pipeline after crews identified the source of a leak of refined products east of Everett, Washington.

Washington declared a fuel emergency last week and Oregon followed suit on Monday in response to the system shutdown, which has disrupted jet fuel supplies to Seattle-Tacoma International Airport.

The Olympic Pipeline moves refined petroleum products including gasoline, diesel and jet fuel from northern Washington to Oregon and consists of one 16-inch diameter pipeline and one 20-inch pipeline.

Crews restored the 16-inch segment of the pipeline system on Tuesday morning after finding no indications of a leak, BP said in an emailed statement. After conducting tests, they were able to confirm a leak in the 20-inch segment and repairs are being planned.

BP did not provide timelines for repair of the 20-inch pipe and the full restart of the system.

A refined products discharge on the Olympic Pipeline was first reported on November 11. BP shut the entire pipeline system a week later, halting product deliveries.

Major carriers including Alaska Airlines (ALK.N) , opens new tab and Delta Air Lines (DAL.N) , opens new tab have implemented plans to minimize the impact of the pipeline disruption on flights out of Seattle-Tacoma International Airport during the busy Thanksgiving travel week by hauling extra fuel via tanker trucks and inbound flights and adding fuel stops to outbound flights.

"Delta is operating our full Seattle hub schedule and has discontinued fuel stops on select long-haul flights," the carrier said on Tuesday.

"We have discontinued all planned fuel stops but will continue to tanker and truck in additional fuel on a reduced basis as the pipeline increases to normal capacity," Alaska Airlines said.
