The operator of the trans-Alaska pipeline system pushed back to Friday its goal for resuming the flow of oil through the 800-mile (1,300-kilometer) line shut down earlier this week after a contained spill.
Operator Alyeska Pipeline Service Co. had hoped to restart the line Thursday night.
But spokeswoman Michelle Egan says the process of getting back on-line is taking longer than expected. She says a restart as early as "first thing" Friday morning appears more likely.
