UPDATE: December 4 at 3:30 p.m.
Crews from Grant PUD and GrayMar Environmental resumed efforts to clean up a mineral-oil spill in the Columbia River at Priest Rapids Dam, PUD announced.
The spill occurred on December 3 during maintenance of a generating unit.
“While these kinds of spills are rare, we do take them very seriously,” said Jeff Grizzel, Grant PUD’s Senior Vice President of Power and Marketing Operations. “We have a spill response plan that includes regular training. We are now following that plan and using that training to work as quickly as possible to safely remove oil from the river.”
Absorbent booms were installed at Vernita Bridge, about nine miles downriver from the dam, to address the spill. The cause and quantity of the spill remain under investigation.
Grant PUD is working with the state Department of Ecology on the cleanup.
Boaters are advised to avoid the river between Priest Rapids Dam and Pasco during this effort.
Those spotting oiled wildlife downstream are urged to contact the Washington Department of Fish & Wildlife at 800-222-4737.
