![]() These sediments are the limestone, shell and dolomite formations that are mined today. ![]() Over the millennia, their remains slowly built up layers of sediment thousands of feet thick. When they die, the shells fall to the sea bed. Many invertebrate animals (animals without backbones) take calcite from sea water to construct their shells. During this time, limestones formed by chemical deposition and the accumulation of shells from sea creatures. ![]() Limestone, shell and dolomite are types of marine deposits that have accumulated in Florida over millions of years during times when the state was covered over with seawater or shallow marshes. Permits or authorizations from other local, state or federal agencies may also be required prior to mining.Ĭlick for a full-page interactive map of non-phosphate mine boundaries in Florida. Florida utilizes a joint application for ERP and 404 for more information regarding the 404 permitting program, please see the State 404 Program page, Chapter 62-331, F.A.C., and the 404 Applicant's Handbook.

For mining activities that involve dredging or filling in state-assumed waters, a State 404 (dredge and fill) permit would also be required. ![]() An Environmental Resource Permit (ERP) is also required for limestone, shell and dolomite mining projects. Reclamation standards for limestone, shell and dolomite mining are detailed in Part II of Chapter 211, Florida Statutes (F.S.), Part III of Chapter 378, F.S., and Chapter 62C-36, Florida Administrative Code (F.A.C.). ![]() The Mining and Mitigation Program administers reclamation, environmental resource/stormwater management, and federally-delegated dredge and fill (State 404) permit programs for mining operations in Florida, including limestone, shell and dolomite mines. ![]()
