Stormwater Pollution Impact

The National Pollutant Discharge Elimination System (NPDES) is a federal program administered by the Environmental Protection Agency (EPA) which regulates discharges into waterbodies of the United States. Historically, this was mostly limited to Wastewater Treatment Facilities and Industrial Dischargers. In the late 70s and early 80s, the U.S. EPA began looking at the effects of stormwater pollution and runoff, and determined that approximately 13% of rivers and streams, 18% of lakes, and 32% of estuaries were impaired as a result of stormwater. As more open land is developed, the impacts associated with stormwater increase. The impervious surfaces associated with developed areas result in increased stormwater volume, velocity, and flooding. Pollutants picked up by the runoff and deposited in waterbodies, such as suspended solids, fecal coliform, metals, and oils, result in reduced habitat areas and aquatic populations, decreased groundwater supplies, health issues, and reduced recreational areas. EPA then began developing a set of regulations to minimize the impacts of stormwater.

Regulations / MS4

The stormwater regulations, or MS4 Program (Municipal Separate Storm Sewer System) was implemented in stages.

  • Phase I of this program was initiated in 1990 and regulated stormwater discharges from 11 industrial categories, construction sites disturbing more than 5 acres, and medium and large municipalities.
  • Phase II of this program was implemented in 1999. This phase expanded the definition of "No Exposure" for light industrial, and regulated construction sites between 1 and 5 acres and small municipalities, such as South Hadley.

Control Measures

The Stormwater NPDES General Permit for small MS4's was issued for 5 years, and specified the minimum control measures that communities had to implement and reporting requirements. The 6 minimum control measures are:

  • Public Education and Outreach
  • Public Participation and Involvement
  • Illicit Discharge Detection and Elimination (IDDE)
  • Construction Site Runoff Control
  • Post Construction Site Runoff Control
  • Pollution Prevention / Good Housekeeping

Each individual community selected the Best Management Practices (BMP's) it would use to comply with each component over the course of the 5 years.

Regional Stormwater Committee

The Town of South Hadley is a member of a Regional Stormwater Committee, coordinated by the Pioneer Valley Planning Commission (PVPC). The primary objective of this committee is to develop and distribute materials to comply with the Public Education and Outreach and Public Participation and Involvement BMP's, but on a regional rather than community level. Alone, and in partnership with other organizations like "Think Blue", the committee has done a lot of outreach utilizing all types of media - radio, television, and print. Most recently is the development of stormwater fliers for general business (PDF), and specific ones for the automotive (PDF) and food service (PDF) sectors. There is also one on the importance of scooping the poop (PDF) for pet owners.
