ERP Dredging and Filling

What is Dredge and Fill?

Dredging means excavation in wetlands or other surface waters or excavation in uplands that creates wetlands or other surface waters. Filling means deposition of any material (such as sand, dock pilings or seawalls) in wetlands or other surface waters.

The surface waters regulated under the dredge and fill program include bays, bayous, sounds, estuaries, lagoons, rivers, streams, the Gulf of Mexico, the Atlantic Ocean, most natural lakes, and all waters and wetlands (natural or artificial).

Ultraviolet (UV) Disinfection for Domestic Wastewater

The vast majority of domestic wastewater treatment facilities in Florida use chlorination for disinfection. However, there are some rather significant concerns associated with chlorination including the production of potentially hazardous byproducts (chlorinated organic compounds), toxicity concerns from chlorine residual for the biota in receiving surface waters, and the potential hazards associated with handling the chlorine at the treatment plant.
