Storm Water


Storm water runoff is generated when precipitation from rain and snow melt events flows over land or impervious surfaces and does not percolate into the ground. As the runoff flows over the land or impervious surfaces (paved streets, parking lots, and building rooftops), it accumulates debris, chemicals, sediment or other pollutants that could adversely affect water quality if the runoff is discharged untreated. The primary method to control storm water discharges is the use of best management practices (BMPs). In addition, most storm water discharges are considered point sources and require coverage under an NPDES permit. For more information about the Stormwater program, visit EPA’s web site for the Stormwater Basic Information page.

Small Municipal Separate Storm Sewer System (MS4)
Federal regulations that were issued by the United States Environmental Protection Agency (EPA) established permit requirements within the National Pollutant Discharge Elimination System (NPDES) for discharge to surface water from certain MS4s. The intent of these regulations is the improve water quality of the waterways in the United States. The permit requirement applies to small MS4s that have been designated by Pennsylvania Department of Environmental Protection (PEDEP).
