Stormwater Regulations and the MS4 Permit

The City is regulated under a stormwater permit issued by the Virginia Department of Environmental Quality which allows the City to discharge stormwater from its municipal separate storm sewer system (MS4) directly into local waterways.

Under this permit, the City must implement a series of programs intended to reduce pollutants entering the City’s stormwater system and thereby protecting (and improving) the water quality in the City's waterways. These programs include:

  • ​Constructing stormwater management projects that improve water quality

  • Implementing an erosion and sediment control program for construction sites

  • Implementing a stormwater management program to control runoff from development areas

  • Maintaining and operating City-owned facilities, roads, and parking lots to minimize polluted runoff

  • Controlling the storage and application of pesticides, herbicides, and fertilizer at City facilities and on City property to minimize polluted runoff

  • Locating and eliminating illicit discharges and improper disposal into the storm sewer system

  • Inspecting sanitary sewers to prevent leaks into the storm sewer system

  • Developing and implementing a program to reduce floatable trash in waterways

  • Implementing programs to prohibit the disposal of used motor vehicle fluids, household hazardous waste, sanitary sewage, grass clippings, leaf litter, and animal wastes into the storm sewers

  • Coordinating with the Fire Department and other City departments to prevent, contain, and respond to spills that may discharge pollutants into the storm sewer system

  • Identifying polluted stormwater discharges from industrial and high-risk facilities

  • Inspecting, operating, and maintaining the storm sewer system and all City-owned stormwater management facilities

  • Implementing a program to ensure that privately-owned stormwater management facilities are maintained and inspected regularly

  • Mapping the storm sewer system including each outfall and the area draining to the storm sewer system

  • Controlling polluted stormwater runoff from all City-owned properties with good housekeeping and pollution prevention measures

  • Developing and implementing a public education plan to minimize pollutants in stormwater runoff

  • Conducting stormwater training for municipal employees

  • Coordinating with the Virginia Department of Transportation (VDOT) where the City's storm sewer is interconnected with VDOT's storm sewer

  • Developing and implementing action plans to reduce pollutants and excess nutrients from entering the Chesapeake Bay and other waterbodies with TMDLs​​

  • Monitoring Stormwater Quality
