ANCHORAGE - Alaska and Alyeska officials say the crude oil spill at a pipeline station near Delta Junction apparently was held within a lined, bermed containment area.
The Department of Environmental Conservation says about 56,000 gallons of pooled oil from the estimated 210,000 gallon spill has been removed. It was sent to the tanker terminal in Valdez for recycling.
The Anchorage Daily News reports the cleanup work now focuses on saturated gravel above the liner at Pump Station 9.
Meanwhile, state and federal authorities are investigating what went wrong in the May 25 spill that shut down the pipeline for three days.
Crews were testing a backup system when batteries failed and a storage tank overflowed.
