SAVANNAH -- A fuel tank ruptured Sunday on a ship at Georgia Ports' Ocean Terminal, causing what was described as a "significant" oil spill on the Savannah River just west of the Talmadge Bridge, closing the river to vessel traffic and filling the air with pungent diesel fumes.
U.S. Coast Guard Petty Officer Bobby Nash said late Sunday the river would remain closed as cleanup efforts continue overnight.
"The source of the actual spill has been secured," Nash said shortly before 9 p.m. "No more fuel is coming out."
The 625-foot Liberty, owned by American Roll-on Roll-off Carrier LLC, was damaged as it was departing the port facility about 11:30 a.m, puncturing its hull and rupturing its starboard fuel tank.
The puncture had the potential to release as much as 65,000 gallons of fuel. By nightfall Sunday, an estimated 7,000 gallons of diesel had spilled.
Coast Guard Lt. Greg Riley said, "We have spill-containing booms as far down river as Fort Jackson and along River Street. We have a unified command center set up with industry and inter-agency partners. We have a lot of equipment deployed and more on standby."
He added: "It's red dye diesel, which is low-sulfur, so it's not a hazmat situation. Still, it's never good when you have that much fuel in the river."
Representatives of the Georgia Department of Natural Resources' Environmental Protection Division sampled the air and determined the incident posed no risk to public health, according to GPA spokesman Robert Morris.
Coast Guard Air Station Savannah conducted a flight to assess the environmental impact, and Coast Guard Marine Safety Unit Savannah was coordinating cleanup efforts, conducting shoreline assessments and investigating the cause of the incident, Nash said.
Jenifer Kimble, a spokeswoman for Crowley Maritime Corp., representing the vessel's owner, said assessments of the damage are under way.
"We're working with local authorities and the Coast Guard," she said. "Obviously the safety of the people of Savannah and surrounding environment is our top priority at this time."
Hazardous materials technicians from Savannah Fire & Emergency Services were also mobilized in a supportive role until about 6 p.m., said Mark Keller, spokesman for the fire department.
"We're there in an advisory role," Keller said. "We've got some containment equipment that can be utilized if needed."

The "red dye" in the fuel is more harmful to aquatic life than the removed sulfur would have been.
