Stormwater Pollution Prevention Inspector — no specific state certification required, but must be trained and knowledgeable in stormwater BMPs

Discharge Standards

Turbidity Limit

Florida's water quality standards are set by rule and apply based on water body classification (Class I through Class V). Special protection applies to Outstanding Florida Waters (OFWs).

Post-Construction

Yes
Post-construction stormwater management is primarily regulated through the Water Management Districts' Environmental Resource Permit (ERP) program. Florida has 5 water management districts with varying specific requirements.

State-Specific Notes

Florida is unique in having a dual-permit system: the FDEP Generic Permit (stormwater) AND the Water Management District ERP (stormwater and flooding/floodplain). Both may apply to the same project. Projects in wetlands face additional scrutiny.
