The Florida DEP filed its own complaint against BP and other oil spill defendants on March 5 in U.S. District Court for the Northern District of Florida, Pensacola Division.
Dave Dunwoody, News Director at WUWF, explains the situation well:
The litigation was filed Wednesday in Panama City, by the Florida Department of Environmental Protection and Fish and Wildlife Conservation Commission. The idea is to join the existing federal lawsuit now on trial in New Orleans.
After Thursday’s Cabinet meeting, Governor Rick Scott was asked about the timing of entering the case.
"It's the right time to hold BP accountable for environmental harm to our state," said Scott. "So that's why we joined in the lawsuit."
Florida's lawsuit names the firms Anadarko, Transocean and Triton Asset Leasing as defendants. It’s separate from one filed by the state last April against BP and contractor Halliburton. That action seeks about $5.5 billion in lost revenues related to the oil spill.
In April 2011, the state rejected a chance to join the original federal lawsuit. At the time, Scott said he wanted to make sure Florida was "treated fairly" in reimbursement from BP.
Officials with the Attorney General's Office also said at that time a settlement could be reached without litigation, as early as the summer of 2011, unless the oil company refused to cooperate. Scott said if no agreement were reached, a claim would be filed through the Oil Pollution Act rather than joining the case.

Zack McDonald at The News Herald explains the nature of the federal litigation further:
Florida also is seeking damages to past and/or future removal costs and natural resource damages, including the loss of recreational and other uses of those resources.
...
The case filed is separate from the suit filed by the Attorney General's office last year. The Attorney General's suit deals with economic losses Florida suffered as a result of the Deepwater Horizon oil spill. Wednesday’s filing seeks to hold the named defendants accountable for injuries to the environment the state suffered as a result of the oil spill.
However, Attorney General Pam Bondi also is seeking a declaratory judgment establishing the liability of BP and other companies for the natural resource damages sustained as a result of the Deepwater Horizon Oil Spill.
