Albemarle County is one of several local entities responsible for implementing a municipal stormwater program under the National Pollutant Discharge Elimination System administered by the Virginia Department of Environmental Quality (DEQ).  The permit authorizes the County to discharge pollutants (from stormwater) into local waters from a municipal separate storm sewer system, or MS4.

The 5-year permit requires the County to develop and implement a Program Plan to manage stormwater and reduce impacts to waterways. Our first permit was issued in 2003; subsequent permits were issued in 2008, 2013, and 2018.The Program Plan describes how the County intends to meet specific requirements called for in each of the following six Minimum Control Measures (MCM):

  • public education and outreach
  • public involvement and participation
  • illicit discharge detection and elimination
  • construction site stormwater runoff control
  • post-construction stormwater management in new development and redevelopment
  • pollution prevention / good housekeeping

We are currently operating under and periodically enhancing a Program Plan to address the permit requirements, including pollutant load reductions as part of the Chespeake Bay TMDL. We encourage the public to review these plans and submit comments to the staff contact at the bottom of this page. Our Program Plan will be revised prior to April 30, 2019 to meet requirement of the 2018-2023 permit.
