Tampa-The Mosaic Co. has announced it has received approval of its permit from the U.S. Army Corps of Engineers for its 10,000-plus acre expansion at its South Fort Meade Mine in Central Florida. The company said work on the new area would begin next month. The Corps gave its approval after the U.S. Environmental Protection Agency and U.S. Fish and Wildlife Service offered their approvals. The process to obtain permitting from all local, state, and federal agencies took many years. The mine was opened in 1995 in Polk County and produces about 6.6 million tons of phosphate rock a year. The mine will result in about $42 million in benefits for Hardee County and employ about 250 workers, as well as a large number of contractors.
