Stormwater runoff is generated when precipitation from rain and snow melt events flow over land and impervious surfaces and does not infiltrate into the ground. The runoff from streets, lawns, farms, construction and industrial sites pick up fertilizers, dirt, pesticides, oil, grease and many other pollutants and discharge into our lakes, streams and rivers. This untreated discharge is detrimental to our water quality as it can adversely affect our drinking water supply and environment. Best Management Practices (BMPs) such as detention/retention/infiltration basins, are already in place to help keep our water clean.
Chalfont Borough regulates stormwater management through a permit that is obtained from the Pennsylvania Department of Environmental Protection (PADEP) through the National Pollution and Discharge Elimination System Phase II (NPDES)/Municipals Separate Storm Sewer System (MS4). This is a federal requirement from the United States Environmental Protection Agency (USEPA) that is administered by the PA DEP. The PA Stormwater Best Practices Manual and MS4 Overview & Fact Sheets are in the links below:
This NPDES Permit is broken up into six minimum control measures to be regulated and enforced by the Borough. These minimum control measures include:
Chalfont Borough has begun monitoring and testing storm sewer outfalls that have flow during dry periods. The Borough asks all residents to cooperate with the inspectors, as some outfalls are located on private properties.
For any questions or concerns regarding stormwater or to report illicit discharges to the storm sewer system please call the Borough at 215-822-7295.
There are many ways you can help the Borough with its stormwater program and participate in volunteering programs that will keep trash, debris and other pollutants out of the storm sewer system. For more information on ways to get involved with your community, please visit the following sites:
