BP Patrols for Alabama, Florida and Mississippi end this month but some are now saying crews are needed to look for tar balls left behind.
Beach visitors say they are still stepping on tar balls. The Coast Guard investigates beach pollution and along with BP says there are not enough tar balls to warrant daily cleaning crews.
Environmentalists say many people cannot identify tar balls even if they see them, which poses a problem.
BP is still paying for cleanup work and regular patrols in Louisiana.
