The U.S. Coast Guard on Monday said it expects a “tapered” resumption of vessel traffic in the Houston Ship Channel after an oil barge spill shut it for a third day but gave no timeline for the reopening. “We will begin process of tapered - more like a tapered, not a floodgate - resumption of marine traffic,” Capt. Brian Penoyer, commander Coast Guard sector Houston-Galveston and captain of the Port of Houston, told reporters on Monday, with no hint of when. The shutdown stopped oil deliveries to Houston-area refineries, or one-tenth of U.S. refining capacity, and forced the second-largest refinery in the country to curb production.
