JUNEAU - Oil flow through the trans-Alaska pipeline system is again over 600,000 barrels a day after a contained spill last month that temporarily shutdown the 800-mile line.
The pipeline was idled for nearly 80 hours after operator Alyeska Pipeline Service Co. said a power failure during a planned shutdown caused normally closed valves to open. An estimated 5,000 barrels of oil spilled into a containment area. The line restarted May 28.
In April, an average of 645,113 barrels of oil per day moved through the line. On Monday, Alyeska spokesman Matt Carle said the rate was about 606,000 barrels a day.
He said a relief tank that overflowed remained off-line and that required, continual monitoring at the site continued.
