Mandatory Phosphate Program

The Mandatory Phosphate Program (MANPHO) is responsible for administering the rules related to the reclamation of lands mined for phosphate after July 1, 1975, and the rules related to Environmental and Wetland Resource Permits for phosphate mined lands. (Chapters 378, Part II, and 373, Part IV, Florida Statutes; Chapters 62C-16, 62-312, 62-4, 62-343, 62-341, and 40X -4, Florida Administrative Code). Of the commodities mined in Florida, phosphate mining is the most land intensive, disturbing between 5,000 to 6,000 acres annually; approximately 25-30% of these lands are isolated wetlands or wetlands connected to waters of the state

Program Dealings

  • The Florida Legislature mandated reclamation of lands mined for phosphate after July 1, 1975. Part of our extensive evaluations in reclamation design includes analysis of water quantity impacts, consideration of best available technology, and focusing on preservation of wildlife habitat and resources. Reclamation standards for phosphate lands are detailed in Chapter 62C-16 of the Florida Administrative Code. Reclamation standards for phosphate lands include contouring to safe slopes, providing for acceptable water quality and quantity, revegetation, and the return of wetlands to premining type, nature, function, and acreage.
  • The Integrated Habitat Network (IHN) plan is the focus for the reclamation and permitting efforts for phosphate mining in Central Florida. The IHN is based on a conceptual reclamation plan for the entire phosphate-mining district (approximately 1.3 million acres of land). The goals of the IHN are: replace drainage and hydrologic functions disrupted by mining operations; and, provide quality wildlife habitat and corridor by maximization of habitat replacement, protection and connection. The IHN is not a permit nor is it an approval.
  • Phosphate mining occurs primarily in the central Florida area (Polk, Hillsborough, Manatee, and Hardee counties). One phosphate mining company operates in North Florida (Hamilton County). The phosphate-mining district covers approximately 1.3 million acres of land known as the “Bone Valley”.
  • There are 27 phosphate mines covering more than 491,900 acres. The smaller phosphate mine is approximately 5,000 acres with the largest being approximately 100,000 acres in size. Routine compliance inspections are conducted for mines regulated by the Mandatory Phosphate program to ensure reclamation activities are in compliance with reclamation rules.
  • All phosphate lands disturbed after July 1, 1975 have a mandatory reclamation requirement. As of December 31, 2009, approximately seventy-one percent (71%) of the land mined for phosphate since July 1, 1975 have been reclaimed. The rest of the acreage is under different types of mining operations.
