SWPPP (Storm Water Pollution Prevent Plan)

Through the City of Roseville’s Municipal Separate Storm Sewer System (MS4) Permit, Roseville is required to develop, implement, and enforce a SWPPP.  The SWPPP is designed to reduce the discharge of pollutants from the MS4 to the Maximum Extent Practicable (MEP), to protect water quality, and to satisfy the appropriate water quality requirements of the Clean Water Act.

Stormwater Pollutants
Rain and melting snow act like a water hose, washing the landscape free of loose dirt and grime.  While a good washing helps spruce up our communities after a long winter or summer dry spell, it does little for the health of our rivers, lakes and wetlands.  That is because materials washed off the hard surfaces in our towns and cities eventually end up in the water, where they can become harmful pollutants.

Pollution caused by rain and snow melt washing the landscape goes by several names.  It is called stormwater pollution because it is caused by storms.  It is called runoff pollution because it is carried by rain and snow melt runoff, and non-point source water pollution, a technical name meaning it is different than point source water pollution. Point source water pollution is the type of water pollution that comes from an industrial or wastewater discharge pipe — a definite point, or location, on the landscape.

Controlling stormwater pollution is a challenge because sources of pollution come from many locations across the landscape and is associated with weather — something we cannot control. Controlling stormwater pollution requires everyone’s action, from the homeowner to the business owner, from the road builder to the street sweeper.

The main stormwater pollutants harming Minnesota’s water are:
  • Sediment
  • Nutrients
  • Bacteria
  • Toxics
  • Heat
Public Meetings
The Roseville Public Works, Environment and Transportation Commission holds an annual public meeting on the Municipal Separate Storm Sewer System (MS4) and Storm Water Pollution Prevention Plan (SWPPP). Public comments received during this meeting are included in the city’s annual report to the Minnesota Pollution Control Agency. 

Annual reports submitted to the PCA are listed below, along with the most recent MS4 Permit the City holds. These documents are available for download, or can be picked up from the Engineering Department. in City Hall.
