What is the NPDES Storm water Program?
The National Pollutant Discharge Elimination System (NPDES) Storm water Program regulates storm water discharges from three potential sources: municipal separate storm sewer systems (MS4), construction activities, and industrial activities.
Most storm water discharges are considered point sources, and operators of these sources may be required to receive an NPDES permit before they can discharge.
This permitting mechanism is designed to prevent storm water runoff from washing harmful pollutants into local surface waters such as streams, rivers, lakes or coastal waters. (Source: US EPA)
Polluted stormwater runoff is commonly transported through Municipal Separate Storm Sewer Systems (MS4s), from which it is often discharged untreated into local waterbodies.
To prevent harmful pollutants from being washed or dumped into an MS4, operators must obtain a NPDES permit and develop a stormwater management program.
Many fact sheets detailing the Minimum Control Measures (MCMs) that COLEBROOKDALE Township is required to comply with every year can be found here.
Please understand that from time to time Township employees may be on your property to inspect swales, pipes and inlets for needed repairs as a requirement of our NPDES MS4 Permit.
