Tampa-By a 6-1 margin, The Mosaic Co. received approval from the Hillsborough County, Fla., County Commission to file an application for a permit to expand its Four Corners Mine by approximately 1,500 acres. At the meeting on March 11, nearby residents sought to complain about noise and pollution from the mining, but were told they would have to wait until a hearing is held on the actual application. The company was expected to file in four-to-five months.
