MS4 Storm Water Discharge Permit Issues To Georgia DOT

The Georgia Environmental Protection Division (EPD) issued National Pollutant Discharge Elimination System (NPDES) Permit No. GAR041000 to the Georgia Department of Transportation (GDOT) for storm water discharges from its municipal separate storm sewer system (MS4) to waters of the State.

This first-time permit requires GDOT to reduce pollutants in storm water through six minimum control measures:


  1. Public Education and Outreach,

  2. Public Involvement/Participation,

  3. Illicit Discharge Detection and Elimination,

  4. Construction Site Storm Water Control,

  5. Post-Construction Storm Water Management, and

  6. Pollution Prevention/Good Housekeeping.

The permit covers GDOT roadway drainage, bridges, detention ponds, etc. in 145 urban areas around the State.
