Stormwater Management / MS4

Municipal Separate Storm Sewer System (MS4) Program  Municipalities throughout the country are under a federal mandate requiring a stormwater management program for reducing pollution impacts from stormwater runoff.  In 2003, Hampton Township was issued a Municipal Separate Storm Sewer System (MS4) Permit through the Pennsylvania Department of Environmental Protection (PADEP) and the Environmental Protection Agency.  Implemented through the Clean Water Act, the permit’s numerous requirements are through six Minimum Control Measures (MCMs).  These six MCMs consist of the following:


      -  MCM #1 Public Education and Outreach
           Educate the public on stormwater pollution and prevention through various distribution methods.

-  MCM #2 Public Involvement and Participation
Promote environmental events for the public to participate.

-  MCM #3 Illicit Discharge, Detection and Elimination
Develop, implement, and enforce a program to detect and eliminate stormwater pollution.

-  MCM #4 Construction Site Stormwater Runoff Control
Reduce stormwater pollution from construction sites within the Township.

-  MCM #5 Post Construction Stormwater Management
Encourage activities such as low impact development, a post construction runoff ordinance, and operation and maintenance of stormwater best management practices.

-  MCM #6 Pollution Prevention and Good Housekeeping
 Educate and train municipal staff to prevent and reduce stormwater pollution from municipal buildings and operations

The PADEP requires the municipalities to submit Progress Reports in order to track progress on each permittee’s stormwater management program.  For the Township’s 2013-2018 MS4 permit, Hampton is required to adhere to the following deadlines:

  • Progress Report 1 due January 4, 2015
  • Progress Report 2 due January 4, 2017
  • Progress Report 3 due May 7, 2018
  • Permit Renewal for 2018 to 2023 MS4 Permit due May 7, 2018

What is Nonpoint Source (NPS) Pollution?

The PA Department of Environmental Protection is responsible for administering the MS4 program, which requires the Township to develop and implement an ongoing program to reduce adverse water quality and aquatic habitat conditions by instituting the use of controls on nonpoint source (NPS) pollution. Nonpoint source (NPS) pollution, unlike pollution from industrial and sewage treatment plants, comes from many diffuse sources. NPS pollution is caused by rainfall or snowmelt moving over and through the ground. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters and ground waters.

As a Resident, How Can You Help?

Being informed on stormwater management is a great way to help the Township meet regulatory compliance for its permit.  Reading through the articles below can provide valuable knowledge on stormwater.  By being an informed citizen, you can help mitigate or stop the harmful effects of stormwater pollution.  Getting involved at environmental events (stream cleanups, recycling, composting, etc.) and reporting stormwater pollution to the Township are ways that you can improve stormwater management within Hampton Township.

Preventing Pollution in Stormwater Runoff

Pollutants and contaminants are carried via stormwater runoff and deposited in our areas lakes, rivers and streams.  This can cause serious damage to the wildlife and ecosystems in the waters of the Commonwealth.  Please read through the following guides prepared by the PADEP for valuable tips in reducing stormwater runoff and potential pollutants.
