JUNEAU - Expect a drop in the flow of oil through the trans-Alaska pipeline over the coming weeks.
Matt Carle, a spokesman for operator Alyeska Pipeline Service Co., says producers have begun their annual summer maintenance, which will cause flow levels to dip.
He says the line also plans to shut down once or twice this summer for its own seasonal maintenance. He says those shutdowns typically last 36 to 48 hours. The first is expected around June 19 or 20.
Last month, a contained spill shut down the 800-mile line for nearly 80 hours.
Carle said Wednesday the rate of oil moving through the line is about 610,000 barrels per day.
