The Department, in coordination with the water management districts, proposes to develop a new Chapter 62-347, F.A.C., to develop updated stormwater quality treatment design and performance standards. These design and performance standards will update the existing criteria and reflect new research on design and performance standards, and particularly today’s understanding of the impact of nutrient discharges from surface water management systems on water quality. The goal of the rule is to provide stormwater quality treatment design and performance standards that can be applied state-wide. The proposed rule will apply to new systems.
