Coast Guard officials said Friday there appears to be no oil leaking from the drilling rig that exploded in the Gulf of Mexico earlier this week.
However, Coast Guard Rear Adm. Mary Landry said that authorities would continue to monitor the situation.
"We have positioned resources to be ready to respond should a spill occur... We will continue to monitor 24/7 for the next several days," she said.
A layer of oil surrounded the burning Deepwater Horizon oil rig, even before it sank Thursday.
Officials had feared 336,000 gallons of crude oil a day could be rising from the sea floor 5,000 feet below.
"If it gets landward, it could be a disaster in the making," said Cynthia Sarthou, executive director for the environmental group Gulf Restoration Network.
Officials are now working to contain the oil that spilled after Tuesday's blast in hopes of preventing any threat to the Louisiana coast's ecosytem.
Workers' Survival Chances 'Slim'
Meanwhile, with each hour that passes, hope is fading for the families of those 11 crew members who went missing after Tuesday's massive explosion.
"Just come home," said Tracey McCay, friend of a missing worker. "That's all we want. Now. We can't wait another day."
The U.S. Coast Guard now calls the chances of survival "slim." Rescue crews called off the search before dawn Friday morning.
"They may have been onboard the rig and unable to evacuate," Transocean Vice President Adrian Rose said.
One-hundred and fifteen workers were able to evacuate and survived the blast. Family members eagerly waited to reunite with them.
"I just arrived and he'll be here in an hour, can't wait to hug him," said Jed Kersey, father of a survivor.
Now, in addition to the hundreds of thousands of gallons of crude oil that could come from the site, the rig also carried about 700,000 gallons of diesel fuel.
Meanwhile, the family of one of the missing workers has filed a law suit against the owners and operators of the rig, alleging negligence.
