The Federal Clean Water Act requires Hanover County to have an MS4 permit. Virginia Department of Environmental Quality (DEQ) issues MS4 permits for the state.

• The permit covers the public system of pipes and ditches carrying rainfall from the urban areas to streams and creeks
• Developed areas contain hard surfaces such as pavement and roof tops that increase stormwater runoff volume
• Runoff and associated pollutants enter local streams through the storm sewer system faster than when the area was a natural forest or meadow
• The permit is designed to reduce pollutants entering the storm sewer system

Please contact Public Works with any stormwater pollution concerns or questions.
