Transportation Separate Storm Sewer System (TS4) General Permit
The Water Quality Unit oversees compliance on the Transportation Separate Storm Sewer System (TS4) Permit. The TS4 permit (effective 11/29/2017) is an all-encompassing permit for the Vermont Agency of Transportation that regulates stormwater discharges from VTrans road and non-road developed lands. It is specific to the unique linear nature of VTran’s infrastructure and allows several stormwater programs to be rolled into one comprehensive regulatory program.
