ST. PETERSBURG, Fla. (AP) - The State's Emergency Operations Center has transitioned to a partial activation in response to the BP oil spill.

State officials said Thursday that because of the success of the so-called "static kill" of the deepwater well off the Louisiana coast - and because the threat of heavy oil to the state of Florida has been reduced - the EOC is scaling back efforts.

State emergency management says it will continue to work with federal, state and local authorities to respond to any future impacts to Florida's coastline.

Also on Thursday, BP began pumping a steady stream of fresh cement into its blown-out oil well, hoping to seal for good the ruptured pipe that blew its top months ago and spewed crude into Gulf of Mexico in one of the world's worst spills.
