The Department is initiating rulemaking to revise subsection 62-621.500(1), F.A.C., the existing Generic Permit for Discharges from Fresh Citrus Fruit Packinghouses to Percolation Ponds, providing permit requirements that meet a level of protection commensurate with potential environmental impacts, based on long-term monitoring data from existing citrus packinghouse facilities under individual permits. The Department proposes to accomplish this by standardizing ground water monitoring, reducing the number of parameters and frequency of effluent and ground water sampling and development of standardized Best Management Practices (BMPs) that can be implemented at all facilities covered under the generic permit.
