Just days before the fourth anniversary of the 2010 Deepwater Horizon disaster and oil spill, the Coast Guard has moved cleanup of Louisiana's coast to a new phase, allowing BP to end its "active" efforts in the area. Earlier Tuesday, the Coast Guard issued a directive transitioning the cleanup to a phase in which Coast Guard teams, BP cleanup crews and equipment will be pre-positioned to respond to new reports of oil as needed. BP said in a news release that the Coast Guard's directive ended patrols of the final three miles of affected shoreline in Louisiana. The move completes a cleanup operation that ended in Florida, Alabama and Mississippi last June. BP executive Laura Folse says BP has spent more than $14 billion on response since the accident happened.
