There was an oil spill at the Valdez Marine Terminal in Alaska Saturday, said officials at the state Department of Environmental Conservation.
The spill appears to be less than 200 gallons of crude oil from the Alaska North Slope, but in the environmentally-sensitive Alaska region, any spill takes on deep importance.
The spill ended up discovered Saturday morning by a worker during routine rounds.
The department said oil reached the water but no one observed any type of sheen on the water.
The cause of the spill is under investigation. The department says the oil might have leaked from loading arms into containment. The department said there was no impact to the trans-Alaska pipeline.
The department will continue to monitor and clean the area.
Skimming vessels have been deployed to the spill site.
