STORMWATER BASIC INFORMATION
Overview
Stormwater runoff is generated when precipitation from rain and snowmelt 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 stormwater discharges is the use of best management practices (BMPs). In addition, most stormwater discharges are considered point sources and require coverage under an NPDES permit. |
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 to 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). Perkiomen Township has been designated by the PADEP as one of these small MS4s. Perkiomen Township’s NPDES Permit Number is 130069. Below is the Annual Reports for Perkiomen Township. A copy of the exhibits are on file at the Perkiomen Township Administration Building.

Stormwater Management Ordinance
Under the MS4 Program, Perkiomen Township is required to adopt, implement, and enforce a Stormwater Management Ordinance. On July 5, 2022, Perkiomen Township adopted a new Stormwater Ordinance, Ordinance No. 239 – Perkiomen Township Stormwater Ordinance No. 2022. | Ordinance No. 239 Perkiomen Township – 2022 Stormwater Ordinance – Adopted |
Minimum Control Measures (MCM)
Under the MS4 Stormwater Management Program, the PADEP established six (6) MCMs:

What You Can Do To Help
As stormwater flows over driveways, lawns, and sidewalks, it picks up debris, chemicals, dirt, and other pollutants. Stormwater can flow into a storm sewer system or directly to a lake, stream, river, wetland, or coastal water. Anything that enters a storm sewer system is discharged untreated into the waterbodies we use for swimming, fishing, and providing drinking water. Polluted runoff is the nation’s greatest threat to clean water. By practicing healthy household habits, homeowners can keep common pollutants like pesticides, pet waste, grass clippings, and automotive fluids off the ground and out of stormwater. Adopt these healthy household habits and help protect lakes, streams, rivers, wetlands, and coastal waters. Remember to share the habits with your neighbors! |

Stormwater Discharges from Construction Activities
Overview
The NPDES stormwater program requires construction site operators engaged in clearing, grading, and excavating activities that disturb 1 acre or more, including smaller sites in a larger common plan of development or sale, to obtain coverage under an NPDES permit for their stormwater discharges. In Pennsylvania, the Department of Environmental Protection (PaDEP) is authorized to implement the Stormwater NPDES Permitting Program. For more information regarding NPDES stormwater permitting from construction activities, please visit PaDEP’s website at www.dep.state.pa.us. |
