Environmentalists are among the many who say there are questions yet to be answered now that the decision has been made to quit using crews to scour the Gulf Coast beaches of Alabama, Florida and Mississippi for tar balls left from the 2010 BP oil spill.

The search for tar balls ended this month as the coastal monitoring program reverted back to what it was before the 2010 oil spill.  The policy is that the Coast Guard will investigate any beach pollution that is reported to them.

Both BP and the Coast Guard report that there are not enough tar balls to continue the daily cleaning crews.

Beach visitors though are still reporting that they are seeing tar balls in some areas, while environmentalists says others can't even identify them.

Regular patrols continue on Louisiana's coast, and BP is still paying for cleanup work since the spill.
