Our MS4 Program
The objective of the Prince William County Public School Storm Sewer System (MS4) program is to protect our local waterways by managing stormwater pollutants by implementing six best management practices (BMPs, or minimum control measures (MCMs). Those six MCMs are:
- Public Education
- Public Involvement/Participation
- Illicit Discharge Detection and Elimination
- Construction Site Stormwater Runoff Control
- Post-Construction Stormwater Management
- Pollution Prevention/Good Housekeeping for Municipal Operations
Our MS4 program is required and part of the Virginia Pollutant Discharge Elimination System. The program is regulated by the Virginia Department of Environmental Quality.
Any comments or questions for additional information on the MS4 program/Annual Report may be obtained from the following Environmental Program Managers:
