Stormwater runoff is rainfall or melting snow that flows over the land or through pipes, and stormwater management facilities into streams, rivers, wetlands, and estuaries. Stormwater runoff contains pollutants such as landscaping fertilizer, heavy metals and oil from vehicles, fecal coliform from pet waste, and sediment from eroding land.  Untreated stormwater discharged into waterways often creates unlivable conditions for fish and other aquatic life, loss of aesthetics, and human health issues.

Because polluted stormwater is a national concern, in 1972 Congress mandated amendments to the Federal Clean Water Act requiring the implementation of controls designed to prevent harmful pollutants from being washed by storm water runoff into local water bodies. The amendments require certain jurisdictions to obtain NPDES Municipal Separate Storm Sewer System permits. Visit the Environmental Protection Agency and Maryland’s NPDES Municipal Stormwater Permits for more information. 

Watershed Protection and Restoration Fund

Established on June 18, 2013, the purpose of the Watershed Protection and Restoration Fund (WPRF) is to provide financial assistance for the implementation of local stormwater management plans through stormwater management practices and stream and wetland restoration activities, as set forth in Section 4-201.1 of the Environment Article of the Annotated Code of Maryland.  The WPRF is a flat rate charged to all improved properties in Charles County, unless otherwise exempted.  If your property should be exempt from the WPRF, an appeal or hardship form should be completed as appropriate.  If you would like to receive up to 50% reduction of the rate, review the credit application below for qualifications, and complete as applicable.

Illicit Discharge Program

An illicit discharge is any discharge to a municipal separate storm sewer system that is not composed entirely of stormwater runoff except discharges from common residential outdoor uses, firefighting activities, or from any legally permitted discharge.  In the event an activity is found to discharge sewage, industrial waste, or other waste into the storm sewer system, the County shall notify the person performing such activities, and shall order such activities be stopped or conducted in such a manner as to avoid the discharge of sewage, industrial wastes, or other wastes into the storm sewer system.  The County’s regulations regarding Illicit Discharge are located in the Storm Drainage Ordinance, Section 19.2.

Summary of the 2014 NPDES MS4 Annual Report

In 2014, Charles County continued watershed restoration efforts to provide management of stormwater runoff from impervious area in the Development District.  The  Acton Lane, Fox Run and Ryon Woods restoration projects were completed, and now provide stormwater management for 19 acres of impervious surface.  These projects are anticipated to improve water quality and aquatic habitat in receiving streams.  Expanding the computer mapping of stormwater infrastructure continued, which will ultimately enhance the ability to manage the storm sewer system.  

Details of these efforts and additional efforts are included in the 2014 NPDES MS4 Annual Report.  For copies of the report appendices please contact the Planning Division at 301-645-0540 or by e-mailing Planning@CharlesCountyMD.gov.
