St. Johns County National Pollutant Discharge Elimination System (NPDES) Permit

In June of 2003, St. Johns County began implementation of the NPDES Phase II Stormwater Management Program as required by the Florida Department of Environmental Protection (FDEP).

The permit will help St. Johns County and its residents protect the environment from stormwater pollution. Find out more about stormwater and stormwater pollution, and advice on reducing and preventing stormwater pollution in your own neighborhood.
