National Pollutant Discharge Elimination System (NPDES) Permit

Components of the City’s NPDES Municipal Separate Storm Sewer System Permit include:

1. Public Education and Outreach: Perform educational outreach regarding the harmful impacts of polluted stormwater runoff. 

2. Public Participation/Involvement: Comply with State and local public notice requirements and encourage other avenues for citizen involvement.

3. Illicit Discharge Detection and Elimination: Implement a plan to detect and eliminate any non-stormwater discharges to the MS4 and create a system map showing outfall locations. 

4. Construction Site Runoff Control: Implement and enforce an erosion and sediment control program for construction activities.

5. Post-Construction Runoff Control: Implement and enforce a program to address discharges of post-construction stormwater runoff from new development and redevelopment areas. (NOTE: This minimum control measure is met by the State’s stormwater permitting program under the Water Management Districts, as a “qualifying alternative program,” thus there is no additional requirement for St. Johns County for this measure.)

6. Pollution Prevention/Good Housekeeping: Implement a program to reduce pollutant runoff from municipal operations and property and perform staff pollution prevention training.
