Our MS4 Program

The objective of the 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). The six MCMs are:

  1. Public Education
  2. Public Involvement/Participation
  3. Illicit Discharge Detection and Elimination
  4. Construction Site Stormwater Runoff Control
  5. Post-Construction Stormwater Management
  6. 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.
