Stormwater Management Program Overview

The Clean Water Act is a Federal Law, passed in 1972, goals of eliminating releases to water of high amounts of toxic substances, eliminating additional water pollution. In 1980, efforts were included in the clean water act to curtain water pollution from runoff and storm water systems. As authorized by the Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) permit program controls water pollution by regulating point sources that discharge pollutants into waters of the United States. Point sources are discrete conveyances such as pipes or man-made ditches. Individual homes that are connected to a municipal system, use a septic system, or do not have a surface discharge do not need an NPDES permit; however, industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters. In 1999, federal regulations extended coverage of the NPDES program to Municipal Separate storm sewer systems (MS4’s) serving populations less than 100,000. Permitting is managed by Pennsylvania Department of Environmental Protection (PaDEP). Hampden Township is required to comply with the NPDES program as a MS4.  To view the Township’s MS-4 Permit click on the following link.

The NPDES stormwater program requires permittees to develop a stormwater management plan that provides the details of how the community will comply with the requirements of the permit. Permits are based on 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

Hampden Township is fully committed to the Municipal Separate Storm water System requirements. Our goals are to protect water quality, and follow the requirements of the Clean Water Act. We would also ask our citizens to be good stewards of the natural resources we all share. Some of the ways you can be a good citizen is to dispose of water properly, clean up after your pets, use fertilizers properly and efficiently to prevent its runoff and store materials that could pollute the water in a safe place. Stormwater is not treated in any way before it reaches the waterways. We also encourage our citizens to monitor the storm inlets in your neighborhoods. No one should dump anything into the storm water system, if you see someone doing this, contact the Township at (717) 761-0119.
