Environmental authorities in Alaska have announced they are investigating an oil spill that occurred last week at Hilcorp Energy’s Drift River shipping terminal.
A report from the Alaska Department of Environmental Conservation (ADEC) said the spill was caused by over-pressurization of a 20-inch fill line when workers were emptying two tanks to prepare for an inspection that happens once a decade.
Initial signs indicate that only around 40 gallons spilled. There were no signs of wildlife being harmed.
Hilcorp is headquartered in Houston, Texas.
The Drift River terminal is located on the west bank of Cook Inlet in the south of Alaska.
ADEC personnel will monitor the clean-up operation.
