Chapter 148: Stormwater Managementfrom The Codebook of the Township of Concord

What builders need to know about stormwater in Concord Township

New Federal Stormwater Management regulations require municipalities in urbanized areas to apply for a National Pollutant Discharge Elimination System (NPDES) permit to discharge stormwater from Municipal Separate Storm Sewer Systems (MS4).

Concord Township is concerned about the protection of its water resources and its watersheds, for the health, safety and quality of life of its current and future residents. Watersheds are areas of land that drain to creeks and other bodies of water. Our creeks are a source of public drinking water supply and provide for habitat and food sources for aquatic life and wildlife, and are attractive settings for fishing, hiking, and other forms of water-based recreation. These streams flow into and impact the water quality of the Delaware Estuary, which is a vital ecological and food resource to our region. Our creeks are also an important part of the scenic beauty, character, and “legacy” of our community.

These water resources are threatened by the impacts of increased stormwater runoff from new impervious surfaces, point source discharges, and non-point source pollution, which results when pollutants are washed into stormwater. This is the focus of the new stormwater law and the new stormwater permits issued to municipalities.

It is a violation of these new laws and the township’s “MS4″ stormwater permit to discharge polluted water into storm drains or onto paved areas which flow to storm drains. Potential pollutants include detergents, chlorine, grease, oil, gasoline, chemicals, or sediment.

Concord Township is working in conjunction with the Chester-Ridley-Crum Watersheds Association
and the Partnership for the Delaware Estuary to promote clean water practices and good stormwater management in our community.

Concord Township is working with the Chester Ridley Crum Watersheds Association (CRC) to improve water quality in our local streams. Your responses to a quick five-minute survey will help us efficiently meet state requirements for public education and outreach on storm water and create programs that will improve our streams.

A video entitled “Stormy Weather – Clean Water Begins and Ends with You” is available from the Rachel Kohl Community Library. This video takes a gritty look at the hazards of stormwater runoff in Philadelphia. The densely populated urban watershed – with its concentrations of people, pets, vehicles and other pollution sources – poses extreme risks to the health of rivers. In this video you will explore the issues, meet organizations that are enhancing the quality of your rivers, and discover how you can help protect your drinking water supply.
