The Energy Department is loaning Marathon Petroleum Co., a refining company, one million barrels of crude oil from the nation’s Strategic Petroleum Reserve after Hurricane Isaac forced the suspension of Gulf of Mexico oil production.

“Today’s announcement is part of the broader federal effort to respond to those impacted by Hurricane Isaac,” Energy Secretary Steven Chu said in a statement. “This emergency loan from the Strategic Petroleum Reserve will help ensure Marathon’s refining operations have the crude oil they need to continue operating.”
