Oil spill at Puget Sound refinery contained

    Seattle (AP) - Washington state officials are monitoring an oil spill at a refinery near Puget Sound.

    The Seattle Times reports crews scrambled to contain the spill that happened late Friday at the Shell Puget Sound Refinery in Anacortes.

    It wasn’t clear Saturday how much spilled when a barge was transferring about 5 million gallons of crude oil from Alaska to the refinery. Washington State Department of Ecology spokesman Ty Keltner says it appears a much smaller quantity spilled.

    Keltner says an inspector will be assessing why the spill occurred. Workers will be looking for any oiled wildlife.

    The spill was at the end of a long pier extending into Fidalgo Bay.

    Shell says crews spotted oil coming from the barge and identified the source as a pressure-relief valve. The valve was secured, stopping the spill.
