MS4 Program Plan

Virginia Stormwater Management Act, the Virginia Stormwater Management Program (VSMP) Permit regulations, and the Clean Water Act regulate discharges from municipal separate storm sewer systems (MS4) as point source discharges. Publicly owned systems such as storm drains, pipes, ditches or swales collecting or moving water to surface waters must obtain permit coverage and develop a stormwater management program.

MS4 programs must be designed and implemented to control the discharge of pollutants from their storm sewer system to the maximum extent practicable in a manner that protects the water quality in nearby streams, rivers, wetlands and bays.

The General Permit for the Discharge of Stormwater from Small MS4s regulates stormwater discharges from MS4s, such as, Department of Defense facilities. The general permit requires small MS4s develop, implement, and enforce a program that includes the following "minimum control measures:"

1) Public Education and Outreach

2) Public Involvement and Participation

3) Illicit Discharge Detection and Elimination

4) Construction Site and Stormwater Runoff Control

5) Post-Construction Stormwater Management in New Development and Development on Prior Developed Lands

6) Pollution Prevention and Good Housekeeping for Municipal Operations
