The Clean Water Act

The Clean Water Act is the federal legislation that governs stormwater management. Stormwater point discharges to waters of the U.S. are regulated using National Pollutant Discharge Elimination System (NPDES) permits. In 1999, federal regulations extended coverage of the NPDES program to local separate storm sewer systems (MS4’s) serving populations less than 100,000. East Pennsboro Township is required to comply with the NPDES program as a MS4. Under the NPDES stormwater program, permittees must develop a stormwater management plan that provides the details of how the community (East Pennsboro Township) will comply with the requirements of the permit. Permits are based on a framework of six minimum control measures:

  • Public education and outreach
  • Public participation and involvement
  • Illicit discharge detection and elimination
  • Construction site runoff control
  • Post-construction storm water management in new development and redevelopment
  • Pollution prevention and good housekeeping for municipal operations and maintenance
More information on this program is available from the Pennsylvania DEP website

East Pennsboro Township Municipal Separate Storm Sewer Systems (MS4)

The goals of all MS4s programs and East Pennsboro Township are to reduce the discharge of pollutants from the township, to protect water quality and to satisfy requirements of the Clean Water Act. East Pennsboro Township would like you to remember that the water and any items that go into a storm sewer go directly into streams. This water is not cleaned in any way and does not go to the waste water treatment plant. East Pennsboro Township needs all of its residents to assist us in keeping our storm water and storm water sewer system clean by doing the following:

  • Dispose of water properly
  • Clean up after your pets
  • Use fertilizers properly and efficiently to prevent excess runoff
  • Store materials that could pollute storm water indoors
  • Keep grass cutting off of the street

What Residents can help watch for:

  • Sediment leaving a construction site in stormwater
  • Spills (Chemical, Gas, Oil)
  • Illegal dumping activity into streams or storm sewers (PLEASE CALL 911 FIRST)
  • Dry weather flows from outfall pipes into streams (72 hours after a rain storm)
Please monitor storm water inlets near your property. Residents may be the first to recognize “illicit” discharges dumping into storm sewers or coming out of from storm sewer outfalls. If you see an “illicit” discharge please contact Stormwater Concerns at 717-732-0711 Option * (star) or the Township Police at 717-732-3633.

A Visit from the Township

As outlined in Section 22-726 of the East Pennsboro Stormwater Ordinance, private stormwater facilities must be inspected by a qualified professional hired by the property owner at a minimum of once per year. The Township also has the responsibility to review these private facilities to ensure adequate operation and maintenance is being performed by the property owner. Therefore, on occasion you may see a Township inspector with identification show up to observe and record the condition of these private stormwater facilities. Please allow these inspectors access to where they need to go. If you have any questions about the program, please call the Stormwater Concerns hotline at 717-732-0711 Option * (star) to discuss.


East Pennsboro Township is partnering with the Cumberland County Planning Department, GreenTreks and other Municipalities to give residents a place to see and post about stormwater activities in their community.
