The wet process phosphoric acid production plant. was first licensed by the Florida Bureau of Radiation Control for the processing and disposal of technically-enhanced concentrations of naturally-occuring radioactive materials (TENORM) in 1983. TENORM occurs as radium scale (radium 226) in pipes and process equipment, and in the associated process-area soils. The Florida Burea of Mine Reclamation administeres a premit for the operation and closure of the phosphogypsum stack; the onsite repository for te mine spoils. The phosphogypsum stack also serves as the repostitory for the mine spoils. The phosphosgypsum stack also serves as the repository for TENORM-contaminated equiptment and soils.
