Two barges hit the bridge before dawn on Sunday, but only one was leaking. It had eight compartments carrying a total of 668,000 gallons of oil. One of those compartments was punctured, and it had about 86,000 gallons of light crude oil in it.
Jozsef said Coast Guard officials continue to estimate that about 7,000 gallons of oil are unaccounted for, but some of it may have seeped into void spaces on the barge rather than into the river.
The oil was being contained with boom, and skimmers were sucking up the crude, Jozsef said.
